Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.

A first embodiment of the present invention relates to an infrared remote control device testing apparatus, as shown in fig. 1 to 2, including: the device comprises a first positioning piece 11, an infrared remote control device to be measured 12, a second positioning piece, an attenuation container 13, an infrared receiver 14 and a distance measuring sensor 15; the first positioning piece 11 is used for fixing the infrared remote control equipment 12 to be detected at a first preset position; the second positioning element is used for fixing the attenuation vessel 13 at a second preset position, wherein the second preset position is located between the first preset position and the infrared receiver 14; the attenuation vessel 13 is used for containing liquid solution; the infrared receiver 14 is used for receiving infrared rays emitted by the infrared remote control device 12 to be measured and measuring the intensity of the received infrared rays, wherein the attenuation container 13 is positioned on a path of infrared ray transmission; the distance measuring sensor 15 is used for measuring the distance between the infrared remote control device 12 to be measured and the infrared receiver 14 when the intensity reaches a preset threshold value.

When testing the remote control distance of the infrared remote control equipment 12 to be tested, the infrared remote control equipment 12 to be tested is placed at a specific position of the infrared remote control equipment testing device, the infrared remote control equipment 12 to be tested is fixed at a first preset position by using the first positioning piece 11, the infrared remote control equipment 12 to be tested emits infrared rays, the emitted infrared rays pass through the attenuation container 13 filled with liquid solution, the infrared ray intensity is attenuated by the liquid solution, and the infrared rays attenuated by the liquid solution are received by the infrared receiver 14. The infrared receiver 14 detects the intensity of the received infrared rays after receiving the infrared rays, and the intensity of the infrared rays detected by the infrared receiver 14 changes correspondingly when the distance between the infrared receiver 14 and the infrared remote control device 12 to be tested is changed. When the intensity of infrared rays detected by the infrared receiver 14 reaches a preset threshold value, the distance measuring sensor 15 arranged near the infrared ray emitting point measures the distance between the infrared receiver 14 and the infrared remote control device 12 to be measured, and since the distance between the infrared receiver 14 and the distance measuring sensor 15 and the infrared remote control device 12 to be measured is larger than the distance between the distance measuring sensor 15 and the infrared remote control device 12 to be measured, the distance between the infrared receiver 14 and the distance measuring sensor 15 is approximately equal to the distance between the infrared receiver 14 and the infrared remote control device 12 to be measured. After the distance between the infrared receiver 14 and the infrared remote control device 12 to be tested is detected, the remote control distance of the infrared remote control device 12 to be tested can be calculated according to the attenuation coefficient of the liquid solution in the attenuation container in the current infrared remote control device testing device. For example, assuming that the attenuation coefficient of the liquid solution in the attenuation container in the current infrared remote control device testing apparatus is 0.5, when it is detected that the distance between the infrared receiver 14 and the infrared remote control device 12 to be tested is 2 meters, the remote control distance of the infrared remote control device 12 to be tested is 4 meters. Thereby reducing the distance to measure the infrared remote control.

In addition, the number of the attenuation containers 13 in the infrared remote control device test apparatus may be set to one, or may be set to a plurality of, and when the number of the attenuation containers 13 is a plurality, liquid solutions of different concentrations or different kinds may be added to the respective attenuation containers 13, for example, distilled water, mineral water, or aqueous solutions with different colors may be added to the different attenuation containers 13. After adding different liquid solutions to the attenuation vessel 13, the accuracy of the attenuation coefficient of the current liquid solution can be verified using the tested infrared remote control device in order to determine a more accurate attenuation coefficient. For example, assuming that the accurate value of the remote control distance of the tested infrared remote control device is X1 m, after the self-prepared liquid solution is filled into the attenuation container 13, the infrared ray emitted from the tested infrared remote control device is received by the infrared receiver 14, when the intensity of the infrared ray received by the infrared receiver 14 reaches a preset threshold value, the distance X2 between the infrared receiver and the infrared remote control device is tested by using the distance measuring sensor 15, and the attenuation coefficients of the attenuation container 13 and the filled liquid solution are X2/X1. After the attenuation coefficient is calculated, the concentration of the liquid solution can be adjusted, so that the flexible adjustment of the attenuation coefficient is realized. For example, a sodium chloride solution with a lower concentration may be added to the attenuation container 13, and after calculating the attenuation coefficient of the solution, if the attenuation coefficient does not satisfy the requirement, the sodium chloride solution may be continuously added to the current attenuation container 13 to increase the concentration of the sodium chloride solution, and the attenuation coefficient of the liquid solution may be changed by adjusting the concentration of the liquid solution, so that the attenuation coefficient may be adjusted more flexibly. In order to make the adjusted attenuation coefficient more constant, when the concentration of the liquid solution is changed, the liquid solution having the changed concentration is preferably a solution having a uniform density.

In addition, a plurality of attenuation containers 13 are arranged in sequence along the infrared radiation direction, each attenuation container 13 is a container in a regular shape, for example, the attenuation container 13 can be a rectangular glass groove, the rectangular glass groove is used for contacting infrared rays close to one plane of the infrared remote control equipment to be tested, and the infrared rays vertically enter the rectangular glass groove, so that the rectangular glass groove cannot refract the infrared rays, the transmission direction of the infrared rays cannot be changed, the influence on the infrared ray transmission angle is avoided to a greater extent, and the influence on the test result of the final remote control angle is avoided. Secondly, in order to further reduce the attenuation of the infrared rays by the attenuation vessel 13, the attenuation vessel 13 may be provided as a transparent vessel, thereby increasing the permeability of the attenuation vessel 13.

In addition, the first positioning element 11 of the infrared remote control device testing apparatus includes a fixing plate and a fastener 112, as shown in fig. 2, the fixing plate includes a first baffle 111 and a second baffle 113 that limit the boundary of the left and right directions of the infrared remote control device 12 to be tested, and a supporting plate that limits the boundary of the lower side of the infrared remote control device 12 to be tested, the positions of the first baffle 111, the second baffle 113 and the supporting plate can be changed by using the fastener 112, so as to change the range size of the first preset position, so that the first preset position can accommodate and fix the infrared remote control devices 12 to be tested with different specifications. Taking the second baffle 113 and the fastener 112 as an example, the position of the second baffle 113 is specifically described to be changed, as shown in fig. 3, the fastener 112 includes a nut structure and a stud structure, the nut structure is fixed at a specific position of the infrared remote control device testing apparatus, the stud structure is a movable structure, by rotating the nut structure, the stud structure is controlled to move left and right relative to the nut structure, and the position of the second baffle 113 can be adjusted along with the left and right movement of the stud structure, for example, when the stud structure moves left, the position of the second baffle 113 can move left along with the change of the stud structure, so that the right side boundary position of the first preset position where the infrared remote control device 12 to be tested is located is changed. Similarly, the positions of the first baffle and the supporting plate can be adjusted by using the nut structure and the stud structure of the fastener 112 in a matching manner, so that the position of the infrared remote control device 12 to be tested is adjusted as required, and the infrared emission lamp of the infrared remote control device 12 to be tested is opposite to the emission hole at the center of the infrared remote control device testing device.

In addition, the retainer plate includes a spring 114, a hollow plate 115, a first support 116 and a second support 117, as shown in fig. 2, the spring is inside the hollow plate, the first support and the second support are at both ends of the spring, and part of the first support and part of the second support are outside the hollow plate; when the first barrier 111 and the second barrier 113 move inward, the first support and the second support are pressed by the first barrier and the second barrier to change the length of the spring, and the change in the length of the spring changes the length of the blade.

In addition, the infrared receiver 14 includes a display screen 142, which can display the intensity level of the received infrared signal, so that the received infrared intensity can be more intuitively viewed by the detected person. The infrared receiver 14 may include an indicator lamp 141, a display 142, and a plurality of keys 143, as shown in fig. 4. When the infrared receiver 14 receives the infrared signal, the indicator lamp 141 is turned on, otherwise, when the infrared receiver 14 does not receive the infrared signal, or the intensity of the received infrared signal does not reach the preset intensity, the indicator lamp 141 is turned off. The display 142 is used to display the level of signal strength of the received infrared signal. The buttons 143 are used to set the maximum value, the minimum value, and the like of the intensity level of the infrared signal displayed on the display screen 142. Wherein, the bright state of pilot lamp 141 and the numerical value that display screen 142 shows can be controlled through little processing unit, little processing unit includes an infrared receiving circuit, the circuit is walked and is shown in fig. 5, wherein, infrared receiving tube among the infrared receiving circuit is used for receiving the infrared ray, and convert light signal into the signal of telecommunication when receiving the infrared ray, make infrared receiving circuit be in the conducting state, there is the electric current circulation among the infrared receiving circuit, lead to field effect (MOS) pipe to switch on, and then diode (LED) switches on, there is the electric current to flow and control the diode lamp and give out light in the diode, diode lamp among the circuit can regard as infrared receiver's pilot lamp 141, when the diode lamp sent out light, then explain that infrared receiver receives infrared light. When the intensity of infrared rays received by the infrared receiving tube is stronger, the intensity of signals converted from optical signals to electrical signals by the infrared receiving tube is stronger, the conductivity of the infrared receiving tube is higher, the current flowing through the resistor R is higher, the voltage at two ends of the resistor R is higher, the voltage of the resistor R or the current flowing through the resistor R is measured at nodes C and D at two ends of the resistor R, and the measured voltage value or current value can reflect the intensity of infrared rays received by the infrared receiver 14. For example, if the predetermined voltage value is 4V to 5V corresponding to the first intensity level, the predetermined voltage value is 5V to 6V corresponding to the second intensity level, the predetermined voltage value is 6V to 7V corresponding to the third intensity level, and the like, when the voltage value at the two ends of the resistor R in the infrared receiving circuit is 5.2V, the display screen 142 directly displays the third intensity level, so that the intensity level can more accurately represent the intensity of the infrared signal received by the infrared receiver 14, the range of the voltage value corresponding to each level can be properly adjusted, and the definition of the intensity level is not limited. In addition, the infrared receiving circuit may measure an average value and a maximum value of a current value flowing through the resistor R over a period of time, or an average value and a maximum value of voltage values across the resistor R over a period of time, to determine the average power, the maximum power, and the like of the emitted infrared rays.

In addition, the infrared remote control device testing apparatus further includes an angle gauge, the angle gauge and the distance measuring sensor 15 may be disposed at the same side of the infrared remote control device 12 to be tested, wherein the center of the angle gauge is disposed corresponding to the distance measuring sensor 15, and is used for measuring the deflection angle of the infrared receiver 14 relative to the infrared emission direction, and the deflection angle is directly read by the angle gauge, so that the remote control angle of the infrared remote control device 12 to be tested can be more accurately measured.

Compared with the prior art, the embodiment of the invention has the advantages that the second positioning piece for fixing the attenuation container is arranged in the infrared remote control equipment testing device, the liquid solution is filled in the attenuation container, the infrared rays emitted by the infrared remote control equipment to be tested are attenuated by the attenuation container filled with the liquid solution after the infrared rays are emitted, and the attenuated infrared rays are received by the infrared receiver. In addition, an indicator light and a display screen are additionally arranged on the infrared receiver, a protractor and the like are additionally arranged on one side of the distance measuring sensor, and a tester can quickly and accurately test specific indexes such as the remote control distance, the remote control angle and the remote control power of the infrared remote control equipment to be tested.

The second embodiment of the invention relates to an infrared remote control equipment testing method, which comprises the following steps: when the infrared remote control equipment to be tested emits infrared rays, receiving the infrared rays attenuated by the liquid solution contained in the attenuation container; and when the intensity of the received infrared ray reaches a preset threshold value, determining the remote control distance of the infrared remote control equipment to be detected. It should be understood that this embodiment is a method embodiment corresponding to the first embodiment, and the embodiment can be implemented in cooperation with the first embodiment. The relevant technical details mentioned in the first embodiment are still valid in this embodiment, and accordingly, the relevant technical details mentioned in this embodiment can also be applied to the first embodiment.

The method for testing the infrared remote control device in the embodiment is shown in fig. 7, and includes:

step 701, receiving infrared rays attenuated by liquid solution contained in an attenuation container when the infrared remote control device to be tested emits infrared rays.

And step 702, determining the remote control distance of the infrared remote control equipment to be tested when the intensity of the received infrared rays reaches a preset threshold value.

Specifically, the laser emission path of the distance measuring equipment is preset to be overlapped with the infrared emission path of the infrared remote control equipment testing device, so that the error of the distance measured by the distance measuring equipment is reduced. After the preparation work is finished in advance, the infrared remote control equipment to be detected is enabled to continuously emit infrared rays, the emitted infrared rays are attenuated through the attenuation container filled with the liquid solution, the infrared rays attenuated through the liquid solution filled in the attenuation container are received through the infrared receiver, the distance between the infrared receiver and the infrared remote control equipment to be detected is moved, and when the intensity of the infrared rays received by the infrared receiver reaches a preset threshold value, the remote control distance of the infrared remote control equipment to be detected is determined.

When the distance between the infrared receiver and the infrared remote control device to be measured is adjusted, the adjustment can be performed according to the on-off condition of the indicator lamp of the infrared receiver, for example, when the indicator lamp of the infrared receiver emits light, the distance between the infrared receiver and the infrared remote control device to be measured is increased, when the indicator lamp of the infrared receiver is turned off, the distance between the infrared receiver and the infrared remote control device to be measured is reduced, and finally, when the indicator lamp is in a critical state of an off state and a light-emitting state, the measured distance between the infrared receiver and the infrared remote control device to be measured is used as the remote control distance of the infrared remote control device to be measured. Or, the remote control distance may be measured according to a value displayed on a display screen of the infrared receiver, for example, when the value displayed on the display screen is greater than a preset value, the distance between the infrared receiver and the infrared remote control device to be measured is increased, otherwise, when the value displayed on the display screen is less than the preset value, the distance between the infrared receiver and the infrared remote control device to be measured is decreased, and when the value displayed on the display screen is the preset value, the distance between the measured infrared receiver and the infrared remote control device to be measured is used as the remote control distance of the infrared remote control device to be measured.

After the remote control distance of the positive direction of the infrared remote control equipment to be tested is determined, the distance between the infrared receiver and the infrared remote control equipment to be tested is adjusted to a preset distance, the adjusted infrared receiver is positioned in the positive direction of infrared emission, the direction of the infrared receiver relative to the infrared remote control equipment to be tested is adjusted until the intensity of infrared rays received by the infrared receiver reaches a preset intensity, namely, if the preset distance is 2 meters, the infrared receiver is adjusted to the positive direction of the infrared remote control equipment to be tested and is two meters away from the infrared remote control equipment to be tested, because the set preset distance is smaller than the remote control distance, the intensity of infrared rays received by the infrared receiver is certainly larger than a preset threshold value at the moment, the direction of the infrared receiver relative to the infrared remote control equipment to be tested is changed, and the receiving range of the infrared, the intensity of the infrared rays received by the infrared receiver is reduced because the emission direction of the infrared rays is not changed, the intensity of the infrared rays received by the infrared receiver is lower when the deflection angle of the infrared receiver relative to the infrared remote control device to be detected is larger, and the deflection angle at the moment is the largest remote control angle in the effective remote control range when the intensity of the infrared rays received by the infrared receiver reaches a preset threshold value, so that the remote control angle of the infrared remote control device to be detected is accurately and quickly confirmed. When the remote control angle is measured, the protractor can be used for being matched with the distance measuring sensor, so that the measured remote control angle is more accurate.

In this embodiment, the protractor and the laser range finder are used in combination, so that remote control and remote control distance can be confirmed more accurately and more quickly.
