Technical Field

The invention relates to a length measuring device and a length measuring system.

Background

Generally, a tape measure is formed in the form of a tape, the surface of which is marked with a scale showing the length for measuring the amplitude or width of a certain space, or measuring the size, length or width of an object to be measured.

There are many kinds of tape measures, and a typical tape measure includes a ruler wound in a coil form, the surface of which is marked with scales, and a case having an inner space for storing the ruler and an entrance for guiding the introduction and extraction of the ruler located in the inner space, so that a user can measure the length of an object to be measured by drawing out the marked ruler and reading the scales located at the end of the ruler and near the main body to the end of the object. The tape measure of this type has the disadvantage that the length of the object to be measured can only be determined by visual inspection, and therefore requires a long time to measure.

Therefore, in order to compensate for this disadvantage, a tape measure has been developed in which the result is marked with a digital code while measuring the distance. The prior art in this regard is korean patent laid-open publication No. 2000-0024064 (5.6.2000), which discloses a "tape measure" that detects and displays on a Liquid Crystal Display (LCD) a digital code display portion constructed as a woven structure of conductors woven between the warp and weft directions of a fiber texture. However, the tape measure may have errors in real-time measurement due to the distance between the conductors. Furthermore, the tape measure has a disadvantage in that the measured length must be manually recorded since a Liquid Crystal Display (LCD) can only display the length and has no storage means.

Fig. 1 is a diagram showing the concept of a length measuring system according to an embodiment of the present invention.

Referring to fig. 1, a length measuring system 1 includes a user terminal 30, and the user terminal 30 includes a length measuring device 10 and a measuring application 300. The length measuring device 10 measures the length of an object or the distance of the object and displays the measured length or distance on a display 200, which will be described below with respect to the display 200. Further, the length measuring device 10 converts the measured length or distance into a digital signal, and transmits it to the user terminal 30 through communication.

The user terminal 30 has a communication module (not shown) for visually displaying the length or distance on the screen of the user terminal by receiving data of the length measuring device 10. The user terminal 30 may be any device that can be installed with a measurement application, such as a smart phone, a Personal Digital Assistant (PDA), a tablet computer, a notebook computer, etc. Also, the length measuring device 10 and the user terminal 30 may use a data communication method of effectively transmitting data, such as radio frequency communication, wireless internet access (WiFi), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), bluetooth, infrared data organization (IrDA), Zigbee protocol (Zigbee), Ultra Wideband (UWB), and the like. In the present embodiment, for convenience of description, a communication method using bluetooth is described, but is not limited thereto.

Fig. 2 is a perspective view schematically showing a length measuring apparatus according to an embodiment of the present invention, fig. 3 is a sectional view schematically showing the length measuring apparatus according to the embodiment of the present invention, and fig. 4 is a block diagram of the length measuring apparatus according to the embodiment of the present invention.

Referring to fig. 2 to 4, the length measuring device 10 may include a housing 110, a strap 120, a reel 130, a first measuring part 140, a second measuring part 150, a distance measuring part 160, an electronic level 170, a control part 180, a storage part 190, a display part 200, a switch part 210, a stopper 220, a first communication part 230, and a power supply part 240.

The housing 110 is protected by accommodating the respective components of the length measuring device 10 therein. The shape of the housing 110 may be any shape capable of accommodating the respective constituent elements. In addition, the housing 110 may have a lead-out port 111 for leading in or out the tape 120, which will be described later.

The belt 120 is accommodated inside the housing 110, and one end thereof is introduced or drawn out to the outside of the housing 110. The band 120 has a scale formed on one side thereof with a certain interval so that a user can read the scale of the drawn band 120 to measure the length of the object. Further, a barcode 121 is formed on one surface of the belt 120. For example, the barcode 121 may be formed by combining shapes of black and white bars of different thicknesses so that the first measurement part 140 described later can recognize the length of the tape 120 drawn to the draw-out port 111.

In addition, the belt 120 may further include a hook 122 for maintaining a state of being hung at the outlet 111 of the case 110. Although the band 120 is shown in the embodiment, the present invention is not limited thereto, and the band 120 may be deformed into various forms (e.g., a wire, a string, or a band).

The reel 130 winds the tape 120 and rotates as the tape 120 is drawn in and out. For example, the reel 130 may be coupled inside the case 110 so that the center portion is rotated, and may wind the tape 120. The reel 130 may include an elastic member wound in a coil shape and connected with the band 120. When the band 120 is drawn out, an elastic member (not shown) may be compressed and deformed, and the band 120 is wound and introduced by elasticity that restores its original shape. At this time, the housing 110 may be provided with a holder 112 at one side to fix the strap 120.

The first measurement unit 140 may generate a first measurement value of the lead length of the tape 120 by recognizing the barcode 121 of the tape 120. For example, the first measuring part 140 includes an encoder 141, and the encoder 141 recognizes the barcode 121 and outputs a corresponding pulse as the position of the belt 120 changes. The first measurement unit 140 is housed inside the housing 110 and is disposed near the extraction port 111. The first measurement unit 140 outputs a first measurement value of the lead length of the tape 120 by recognizing the barcode 121.

The second measuring unit 150 generates a second measurement value by detecting the rotation angle of the spool 130. For example, the second measurement portion 150 includes a drum 151 that rotates in association with the spool 130, a rotation transmission portion 152 that transmits the rotation of the spool 130 to the drum 151, and a rotation angle sensor 153 that generates a first measurement value by detecting a rotation angle of the drum 151. The drum 151 rotates according to the rotation of the reel 130 transferred by the rotation transfer portion 152. At this time, the rotation angle sensor 153 detects the amount of change in the rotation angle of the drum 151, and outputs a second measurement value of the lead-out distance of the belt 120.

The rotation angle sensor 153 may be an oscillation type sensor in which a gear-like ferromagnetic material is disposed at a part of the rotation axis of the drum 151, and the number of convexities and concavities is measured by an electromagnetic coil placed in the vicinity thereof, thereby measuring the number of rotations or the rotation angle. However, the present invention is not limited thereto, and the rotation angle sensor 153 may be any sensor that detects the rotation angle of the drum 151, such as a hall effect sensor, a magnetoresistive sensor, a power generation sensor, an electronic sensor, a photoelectric sensor, or the like.

The distance measuring unit 160 may be disposed at one side of the housing 110, and generate a distance measurement value by remotely measuring a distance of an object. Taking a face of the housing 110 as an example, the distance measuring part 160 may be coupled to a face where the drawing port 111 is located, thereby performing measurement in the drawing direction of the belt 120. Further, the distance measuring section 160 may perform measurement by adjusting the measurement angle. The distance measuring part 160 may include a distance measuring sensor 161, an angle adjusting part 162, and an angle detecting sensor 163.

The distance measuring sensor 161 measures the distance to the object. For example, the distance measuring sensor 161 may receive a signal reflected back by emitting laser light, infrared light, or ultrasonic waves toward the subject. The distance measuring sensor 161 receives the return signal and generates a distance measurement value.

Referring to fig. 5a to 5b, the angle adjusting part 162 adjusts the measurement angle of the distance measuring sensor 161. For example, one side of the angle adjusting part 162 may be coupled to the distance measuring sensor 161, and the other side may be coupled to the housing 110 in a universal joint manner.

Further, when the angle adjusting part 162 is coupled to the housing 110, it may be coupled in a form of a tip end that the distance measuring sensor 161 does not protrude outside the housing 110. At this time, the housing 110 forms a hemispherical recess, and the angle adjusting part 162 may be insert-coupled to the recess. Thus, the angle adjusting part 162 prevents the breakage by the insertion coupling.

The angle detection sensor 163 generates angle information by detecting the direction angle and the inclination angle of the angle adjustment unit 162. Here, as shown in fig. 5a, the directional angle refers to an angle formed by a dotted line formed from the origin in an arbitrary direction and a moving direction of the moved distance measuring sensor, and as shown in fig. 5b, the inclination angle refers to an angle formed by an initial longitudinal direction of the angle adjusting part 162 and a longitudinal direction of the angle adjusting part 162 after adjustment.

When the distance measuring part 160 measures the distance to the object, the distance measuring part 160 may be adjusted to an arbitrary angle to generate measured distance information including angle information detected from the measured distance and angle detecting sensor 163.

Returning again to fig. 4, the electronic level 170 may measure the levelness of the length measuring device 10. For example, the electronic level 170 may include a gyroscope and measure the levelness of the length measurement device 10 such that the generated measurement distance information includes level information. Here, a method of measuring the levelness using a gyroscope is disclosed, and a description thereof will be omitted.

The controller 180 may convert the first measurement value and the second measurement value into the lead-out length information of the tape 120 by mutually rectifying them. For example, the controller 180 may correct an error of the first measurement value due to the interval of the barcode 121 using the second measurement value. Further, for an error of the second measurement value of the change in the rotation amount of the reel 130 occurring when the winding amount of the tape 120 is reduced, that is, when the diameter of the circle around which the tape 120 is wound is reduced, the controller 180 may correct the error using the first measurement value. Further, the control part 180 may correct an error of the second measurement value due to the occurrence of the gap between the tapes 120 using the first measurement value when winding the tapes 120. Further, the control unit 180 may convert the drawn length of the tape 120 or the measurement distance of the distance measuring unit 160 into data. The control unit 180 may control the respective components of the length measuring device 10.

The storage unit 190 stores lead-out length information or measurement distance information. For example, the storage section 190 may include a Magnetic medium (Magnetic Media); optical Media (Optical Media) such as compact discs (CD-ROMs) and Digital Video Discs (DVDs); Magneto-Optical Media (Magneto-Optical Media) such as Floptical Disk (Floptical Disk); hardware storage media such as a Read Only Memory (ROM), a Random Access Memory (RAM), and a flash memory store the lead-out length information or the measurement distance information. The storage section 190 stores lead-out length information or measured distance information at the time of operating the storage switch 211 by an operation of the storage switch 211 described later. The storage unit 190 may store a plurality of lead-out length information or measurement distance information.

The display unit 200 converts the lead-out length information or the measurement distance information into a numerical value and displays the numerical value. The display unit 200 can intuitively display the lead-out length information or the measurement distance information by converting the information into a numerical value. Further, the display section 200 can intuitively display by receiving the lead-out length information or the measurement distance information stored in the storage section 190. Although the position where the display part 200 is disposed is not limited, it is preferably disposed to be exposed to the outer surface of the housing 110.

The switch section 210 includes a plurality of switches for controlling the operation of the control section. The switch section 210 includes a storage switch 211, a communication switch 212, a return-to-zero switch 213, a measurement standard switch 214, and a unit change switch 215.

The storage switch 211 stores the lead-out length information or the measured distance information, or displays the lead-out length information or the measured distance information stored in the storage unit 190 on the display unit 200. For example, when the storage switch 211 is pressed for a certain time, the lead-out length information or the measurement distance information in the measurement is stored. Further, when the storage switch 211 is pressed, the control section 180 may digitize the stored drawing length information or the measured distance information and display it on the display section 200.

Also, the storage switch 211 may be configured in plurality. The plurality of storage switches 211 may be configured such that the storage section stores or outputs the lead-out length information or the measured distance information corresponding to each storage switch at each operation. However, this is just an example, and the storage switch 211 may be configured such that, when operated, the storage section 190 sequentially stores or outputs a plurality of lead-out length information or measured distance information.

The communication switch 212 is a switch for operating a first communication section 230 described later. For example, when operated, the control section operates the first communication section 230 so that the communication switch 212 can be connected to the user terminal 30. Further, during operation, the communication switch 212 may control the control section to transmit the lead-out length information or the measured distance information to the user terminal 30.

The return-to-zero switch 213 is a switch for setting the current measurement size to zero. For example, when the zeroing switch 213 is operated, the control part 180 may set the current value of the drawing length information or the measured distance information to 0, and calculate the drawing length information or the measured distance information measured thereafter based on the current value, and display it on the display part 200.

The measurement standard switch 214 may be a switch for changing a measurement standard. For example, the measurement standard switch 214 may be a switch for changing the measurement standard based on the front or rear of the length measuring device 10. In other words, when the measurement standard switch 214 is operated, the control part 180 corrects the lead-out length information or the measurement distance information by increasing or decreasing the length of the length measurement device 10.

The unit changing switch 215 is a switch for changing the measurement unit. For example, when the unit change switch 215 is operated, the control part 180 may change the unit of the lead-out length information or the measured distance information so as to be displayed on the display part 200.

The stopper 220 may restrict the extraction of the band 120. For example, as shown in fig. 3, the limiting member 220 may be disposed inside the housing 110 in a telescopic cylindrical form. The stopper 220 may have a friction member at one end thereof, and the friction member may be moved in a direction of one side of the belt 120 to generate a friction force on the belt 120, thereby applying a pressure to stop the belt 120.

Here, when the drawing length information or the measured distance information stored in the storage unit 190 is output to the display unit 200, the control unit 180 controls the stopper 220 to draw the tape 120 in accordance with the drawing length information or the measured distance information. In other words, the control part 180 may limit the length of the tape draw by a length corresponding to the stored draw length information or the measured distance information. Thus, when repeated operations such as cutting sizes of the inspection objects are performed, the stopper 220 can limit the lead-out length of the tape 120 based on the lead-out length information or the measurement distance information stored in the storage unit 190 so as to perform the operations.

The first communication unit 230 communicates the lead-out length information or the measurement distance information. For example, the first communication unit 230 may transmit and receive the lead-out length information or the measurement distance information to and from the user terminal 30 by a bluetooth communication method.

The power supply section 240 supplies power necessary for the operation of each component of the length measuring device 10. For example, the power supply part 240 may be a battery. In addition, a photoelectric panel (not shown) may also be disposed at one side of the display part 200, thereby being implemented as a solar cell charged with light. However, this is just an example, and the power supply section 240 may also be in the form of an external power supply. In addition, the shape of the battery may be appropriately modified according to the size of the case.

FIG. 6 is a block diagram illustrating a measurement application according to an embodiment of the present invention.

Referring to fig. 6, the measurement application includes a second communication unit 310, a position recognition unit 320, a length output unit 330, a logical operation unit 340, a three-dimensional modeling unit 350, an image insertion unit 360, and a lead setting unit 370.

The second communication part 310 communicates data with the first communication part 230 through the communication module of the user terminal 30. The second communication unit 310 may receive the drawing length information and the measured distance information of the distance measuring unit through the first communication unit 230 or transmit the drawing length information to be stored in the storage unit 190. The lead-out length information stored in the storage unit 190 can be arbitrarily specified by the user terminal 30.

The position identifying section 320 identifies a position at which the lead-out length information is to be output. For example, the position recognition part 320 may recognize an X-axis, a Y-axis, or a Z-axis with reference to an arbitrary origin as a position where the lead length information is to be displayed. In this case, the position recognition unit 320 may sequentially recognize the lead length information transmitted from the length measuring device 10 in the X-axis, Y-axis, or Z-axis direction with reference to an arbitrary origin. As another example, the position identifying part 320 may identify a position designated by the user terminal 30 as a position where the lead-out length information is to be output. At this time, the position recognition part 320 may recognize between a pair of points input to the user terminal 30 through the touch screen 31 or a separate input device (not shown) as a position where the lead-out length information is to be output. As another example, the position identifying part 320 may identify a position at which the measured distance information is to be output from the angle information with reference to an arbitrary origin.

The length output part 330 outputs the lead-out length information of the identified position to the screen of the user terminal 30. For example, the length output section 330 may output a line having the same length accumulation as the value measured by the lead-out length information or the measured distance information to the identified position. Further, when at least one pair of points has been designated, the length output section 330 may input only a numerical value between the pair of points.

Further, the length output section may output the measured distance information to the identified position. Here, the length output unit outputs the length based on angle information and horizontal information included in the measured distance information.

The logical operation unit 340 may calculate the lead-out length information and calculate each cross-sectional area and volume. For example, when the length output unit 330 outputs the lead-out length information at the position of the x-axis, the y-axis, or the z-axis, the logic operation unit 340 may calculate the length of the x-axis, the y-axis, or the z-axis, respectively, to calculate each cross-sectional area and volume. Further, even if the elongation information is output between a plurality of pairs of dots, the logical operation section 340 can calculate the cross-sectional area and the volume of the overlapped dots.

The logical operation unit 340 may calculate the measurement distance information from the angle information, and may calculate and output the X-axis, Y-axis, and Z-axis distances. Here, the logical operation unit 340 may correct the angle information using the horizontal information. For example, the logic operation unit 340 corrects the azimuth and the inclination by generating an angle of the horizontal information of the length measuring device based on the angle information.

The three-dimensional modeling section 350 models the lead-out length information of the X-axis, the Y-axis, or the Z-axis in three dimensions. For example, when the lead-out length information of the X-axis, Y-axis, or Z-axis is intuitively output to the user terminal through the length output part 330, the three-dimensional modeling part 350 may form a three-dimensional model by combining the lead-out length information of the X-axis, Y-axis, or Z-axis.

The image inserting part 360 may insert an image designated through the user terminal 30 onto the screen of the user terminal 30 as a background. For example, the image insertion unit 360 may specify any one of the images stored in the user terminal 30 and insert the specified image as the background.

When the lead length information input by the user terminal 30 is input, the lead setting unit 370 generates a signal for controlling the stopper in accordance with the input lead length information. For example, the drawing setting unit 370 may generate an input event in which the drawing length information can be input by the user terminal 30. When the drawing length information is input to the input event, the drawing setting unit 370 generates it as a drawing setting signal and transmits it to the second communication unit 310.

When receiving the drawing setting signal, the control section 180 of the length measuring device 10 displays drawing length information corresponding to the drawing setting signal on the display section. The control unit 180 controls the stopper 220 in accordance with the lead length information to control the lead length of the tape 120.

The application control section 380 mutually controls the respective constituent elements of the measurement application 300. Further, the application control section 380 may change the setting of the position recognition section 320 selected by the user terminal 30.

The drive measurement application will be described in detail below with reference to fig. 7 to 9.

Fig. 7 is a diagram showing an example of a drive measurement application according to an embodiment of the present invention.

Referring to fig. 7, the application control unit 380 may set the position recognition unit 320 to recognize the X-axis, the Y-axis, and the Z-axis in order as positions where the lead length information is to be output, with reference to an arbitrary origin 0. Here, the arbitrary origin 0 may be a position set in the position recognition unit 320, or the user may select the arbitrary origin 0 through the user terminal 30.

The length output unit 330 sequentially outputs the lead-out length information or the length measurement information transmitted from the length measuring device 10 to the X-axis, the Y-axis, and the Z-axis identified by the position identifying unit 320. For example, the length output unit 330 forms the first drawn length information or the length measurement information received from the length measuring device into a line on the X-axis, and outputs the line together with the length obtained as a numerical value.

The logical operation unit 340 calculates the lead-out length information and the measured distance information output from the length output unit 330, and calculates and outputs each cross-sectional area and volume. At this time, the calculation is performed in the same unit as the unit selected by the unit changing switch 215, and the calculation is output to the length measuring device.

The three-dimensional modeling section 350 models the lead-out length information of the X-axis, the Y-axis, or the Z-axis in three dimensions. The three-dimensional modeling part 350 may duplicate lines output in the X-axis, the Y-axis, and the Z-axis by a linear array, thereby forming a three-dimensional model of a hexahedron. At this time, when the user selects a setting of forming a circle diameter through the user terminal 30, the three-dimensional modeling portion 350 may be modeled in various forms (a cylindrical sphere, etc.).

Fig. 8 is a diagram showing another example of a drive measurement application according to an embodiment of the present invention.

Referring to fig. 8, the application control part 380 may change the setting of the position recognition part 320 to recognize the position designated by the user terminal 30 as the position where the lead-out length information is to be output. At this time, the position recognizer 320 forms a virtual line L1, and the virtual line L1 connects the arbitrary point P1 designated by the user through the user terminal and another arbitrary point P2. Even if the plurality of points P1, P2, P3, and P4 are designated by the user terminal 30, the position identifying part 320 can identify the virtual lines L1, L2, and L3. Further, the position recognition unit 320 may select the order of the virtual lines so that the user sets the order of the output lengths to measure the object.

At this time, the image may be inserted into the screen of the user terminal 30 through the image inserting part 360. Since the user designates a point through the image, the point can be easily designated.

The length output unit 330 sequentially outputs the lead-out length information or the length measurement information sequentially transmitted from the length measuring device 10 in the order of the virtual lines L1, L2, and L3 identified by the position identifying unit 320.

At this time, the lead-out length information and the measured distance information may be calculated by the logical operation part 340 to calculate and output a corresponding cross-sectional area and volume. Further, the three-dimensional modeling section 350 may also generate a 3-dimensional model by connecting with the virtual lines L1, L2, and L3.

Fig. 9 is a diagram showing still another example of a drive measurement application according to an embodiment of the present invention.

Referring to fig. 9, the application control section 380 may change the setting of the position recognition section 320 to recognize the position of the measured distance information output as a line based on the angle information with reference to an arbitrary origin. In this case, the length output unit 330 may generate a virtual line r based on the measured distance information and the angle information with reference to an arbitrary origin 0. The logic operation unit 340 generates an angle based on the horizontal information of the length measuring device 10 from the angle information, corrects the azimuth and the inclination, and supplies the corrected angle to the length output unit 330. The logical operation unit 340 may calculate the X-axis, Y-axis, and Z-axis distances from the corrected angle information, and output the measured distance information to the screen. Here, the three-dimensional modeling unit 350 may generate a three-dimensional model from the X-axis, Y-axis, and Z-axis distances.
