Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular device structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.

In the prior art, because of the inconvenience of applying a pressure sensor to distance detection, the embodiment of the present invention provides a general inventive concept: the change of resistance or capacitance caused by wheel contact is adopted, so that the judgment condition that the wheel contacts the iron shoe is adopted, the inaccuracy caused by the conventional ultrasonic ranging can be abandoned based on the characteristics, the quicker and more positive response can be obtained by judging whether the wheel contacts the iron shoe relative pressure sensor, and the cost and the process condition can be met.

With respect to the above general inventive concept, an embodiment of the present invention first provides a state detection device, please refer to fig. 2, fig. 2 is a connection topology diagram of the state detection device for an iron shoe according to the embodiment of the present invention;

the state detection device 100 includes:

a touch structure 101 including a plurality of contact pieces 101a, the contact pieces 101a being sequentially disposed along a toe 201 of the skate 200, wherein the contact pieces 101a are either resistive or capacitive;

the conversion module 102 is electrically connected to the touch structure 101, and is configured to receive an analog electrical signal fed back by the touch structure 101 and convert the analog electrical signal into a digital signal;

a controller 103 configured to:

receiving a digital signal;

the coded combination of the digital signals is analyzed according to a preset mapping relationship to determine the state of the skate 200.

The touch pad 101a included in the touch structure 101 may be understood as a touch button, which may be a resistive or capacitive touch pad, and according to the basic common knowledge, an inductive capacitance or a contact resistance exists between any two conductive objects; after the wheel of the rail transit rolls on the toe 201 of the skate 200, since the wheel is a metal conductor and is relatively an ultra-large capacitance/resistance, when the contact piece 101a touches (contacts) the wheel, the induced capacitance or the contact resistance thereof changes rapidly, and according to the different positions of the contact piece 101a, the response output by the contact pieces 101a at different positions is used as a reference condition for judging the rolling position of the wheel.

Taking the contact pad 101a as a capacitive type, the contact pad 101a is connected to the toe 201 of the skate 200 by a pad, and the contact pad 101a may be grounded or in other situations. And the ground can also form an induction capacitor, and under the condition that the surrounding environment is not changed, the ground is relatively an overlarge capacitor. Therefore, the relative capacitance value between the contact piece 101a and the iron shoe 200 is a constant and small value. When a wheel is in close contact with the contact sheet 101a, the total induction capacitance value is increased by the induction capacitance formed by the wheel and the ground of the rail transit in parallel with the induction capacitance formed by the contact sheet 101a and the ground. At this time, the analog electrical signal passing through the contact pad 101a is changed.

When the capacitive contact pad 101a starts to respond, the IC of the conversion module detects that the value of the capacitance of a certain contact pad 101a has changed, and the analog electrical signal passing through the contact pad 101a changes. Since the contact piece 101a has no mechanical structure, all the detections are small changes of analog electric signals, and therefore, the contact piece is more sensitive to various interferences, and therefore, has higher accuracy.

The conversion module 102 is electrically connected to the touch structure 101 to receive an analog electrical signal fed back from the touch sheet 101a, where the analog electrical signal includes a voltage signal or a current signal, and the conversion module 102 is electrically connected to the plurality of touch sheets 101a to receive the analog electrical signal of each touch sheet 101a and to simulate a digital signal converted from the electrical signal.

The controller 103 may be a PLC controller or a programmable microcomputer, and determines the state of the skate 200 by integrating all the digital signals, according to the codes of the real-time feedback digital signals, and according to the relationship between the state preset in the database and the codes of the corresponding digital signals.

In one example, the conversion module 102 is a decoder, and converts the analog electric signal fed back by the touch sheet 101a into a digital signal to be received by an upper computer (the controller 103) and analyzed in the controller 103 to determine the state of the skate.

It can be understood that, since the touch sheets 101a are respectively disposed at different positions of the skate 200, as long as the touch sheets 101a respond correspondingly, i.e. prove that the wheels are rolled to the corresponding positions on the skate, the relative position relationship between the skate and the wheels, and the "state" of the skate at this time can be determined according to the condition reflected by the touch sheets 101 a.

In summary, in the embodiment of the present invention, the contact pieces are arranged on the toe cap of the iron shoe according to the distance, and the contact pieces are resistive or capacitive, so that the characteristic of the change of the resistance or the capacitance of the contact pieces caused by the contact of the wheel with the contact pieces is used as the determination condition for the contact of the wheel with the iron shoe; and determining the final position states of the skate and the wheel according to the coding combination of the digital signals through digital-to-analog conversion. Through the mode, the problem of inaccurate measurement caused by an ultrasonic generator in the prior art can be solved, the ultrasonic generator can be produced within the range which can be realized by the current process level, and the ultrasonic generator has the characteristics of low cost, easiness in implementation and the like.

In view of the above, in order to solve the technical drawbacks of the prior art pressure sensor, a specific embodiment is provided as follows:

referring to fig. 3, fig. 3 is a schematic structural diagram of a module of a state detection device for an iron shoe according to an embodiment of the present invention;

the state detection device 100 includes:

the touch structure 101 comprises three contact pieces 101a, the contact pieces 101a are sequentially arranged along the toe 201 of the iron shoe 200, and the contact pieces 101a are capacitance contact buttons;

the conversion module 102 is electrically connected to the touch structure 101, and is configured to receive an analog electrical signal fed back by the touch structure 101 and convert the analog electrical signal into a digital signal;

a controller 103 configured to:

receiving a digital signal;

the coded combination of the digital signals is analyzed according to a preset mapping relationship to determine the state of the skate 200.

The hardware is described below:

the conversion module 102: for detecting the states of the three touch pads 101a and outputting the states to the controller 103 for calculation through three GPIOs (an interface, an optional feature). When the touch sheet 101a is not touched, three GPIOs are often "1", i.e., a first level, and when there is a corresponding button touched, the corresponding GPIO output is "0", i.e., a second level.

The controller 103: and judging whether the current skate is normally anti-slipping, anti-slipping too close and the skate is pressed tongue according to the combination of the first level and the second level output by the conversion module 102.

Touch sheet 101 a: the three touch pieces 101a are respectively associated with different skate states at different positions on the toe cap according to past experience.

Specifically, the plurality of contact pieces 101a optionally include:

a first contact piece 1011 disposed at an end of the toe 201;

a second contact piece 1012 arranged at the middle position of the toe cap 201;

a third contact piece 1013 provided at the end of the toe 201;

it is understood that the number of the contact pads 101a can be increased to improve the determination accuracy, and the improvement made in the above number is within the protection scope of the embodiment of the present invention.

When the first contact piece 1011 is contacted, the controller 103 determines normal anti-slide; determining that the second contact piece 1012 and the first contact piece 1011 are contacted together; whenever the touch sheet 101a is touched, it is determined that the toe 201 of the iron shoe 200 has been pressed, an alarm is immediately given.

Further, the state detection apparatus 100 further includes:

attitude sensor 104: for detecting whether the skate 200 is in motion or in a stationary state. The controller 103 reads the parameters of the attitude sensor 104, and only when the skate 200 is in a static state, the touch sheet 101a is started to detect, and the movement process is not detected.

Sealing layer 101 b: since the iron shoe toe cap is pressed by the train wheel for a long time, the touch sheet 101a is easily damaged, and for this reason, an inner groove is formed at the toe cap 201 of the iron shoe 200 at the position where the touch sheet 101a is installed, and the touch sheet 101a is placed in the groove and impregnated with the sealing layer 101b on the surface thereof to protect the touch sheet 101 a.

The hardware composition of the state detection apparatus 100 is explained above, and the connection relationship of each hardware and the functions performed by the hardware are further described below:

the conversion module 102 is electrically connected to the contact pads 101a (i.e. the first contact pad 1011, the second contact pad 1012 and the third contact pad 1013) independently to receive the analog electrical signal of each contact pad 101a independently; the conversion module 102 converting the analog electrical signal into a digital signal includes:

step S101, outputting a first level (namely 1) under the condition that the analog electric signal is within a preset electric signal threshold range;

step S102, in case the analog electrical signal is outside the electrical signal threshold range, outputs a second level (i.e. 0).

It is understood that the above steps can be implemented by a preset configuration, for example, the current is output to the contact pad 101a, since the capacitance is small when the wheel is not rolled to the contact pad 101a, and the input and output of the I/0 port connected between the conversion module 102 and the contact pad 101a are both high level, then the output analog electrical signal is approximately 5V voltage, which is represented by 1 (usually, the high level voltage of the chip is 5V). After the wheel is pressed to the contact pad 101a, the capacitance transient increases, and when the input and output of the I/0 port of the conversion module 102 are at low level, which is approximately 0V, it is represented as 0.

Still further, the controller 103 being configured to parse the coded combination of digital signals according to a predetermined mapping relationship to determine the status of the skate further comprises the controller being configured to:

step S201, receiving that the first contact piece 1011 outputs the second level, and the second contact piece 1012 and the third contact piece 1013 both output the first level, and determining that the skate 200 is in the normal anti-slide state;

step S202, receiving that the first contact piece 1011, the second contact piece 1012 output the second level, and the third contact piece 1013 outputs the first level, and determining that the skate 200 is in the anti-slipping over-close state;

in step S203, the first contact piece 1011, the second contact piece 1012, and the third contact piece 1013 are all received to output the second level, or the third contact piece 1013 outputs the second level alone, and it is determined that the skate 200 is in the dangerous state.

In summary, in the embodiment of the present invention, the plurality of contact pieces are provided at the toe cap of the skate, and the first contact piece, the second contact piece, and the third contact piece are respectively associated with the normal anti-slip state, the anti-slip close-up state, and the dangerous state, so that the analog electric signal starts to change according to the change of the capacitance caused by the contact between the wheel and the contact piece, and the first contact piece, the second contact piece, and the third contact piece are used as the determination condition for the contact between the wheel and the skate. Through the mode, the state of the skate can be judged more accurately.

In order to overcome the problem that the upper computer cannot obtain the damage information after the pressure sensor is damaged, please refer to fig. 3 and 4, fig. 4 is a schematic circuit diagram of a part of the state detection device for the skate according to the embodiment of the present invention, and the touch structure device 100 further includes:

a first interface 1014 disposed on the contact patch;

In an optional scheme of the embodiment of the present invention, a capacitance-resistance element, such as a capacitor, an inductor, a resistor, or the like, may be added to the first loop to increase the stability of the loop.

Still further, the touch structure device 100 further includes:

a super capacitor 1016 connected in parallel on the first loop to form a second loop; the second loop refers to the super capacitor connecting pin 1 and pin 2 and connecting the first loop in parallel, and after receiving the power failure of the first loop, the super capacitor 1016 discharges, thereby releasing the opposite analog electrical signal.

Further, diodes are disposed in both the second loop and the first loop, so that the second loop and the first loop have unidirectional conductivity to prevent the super capacitor 1016 from beginning to release an opposite voltage to affect the conversion module 102 when the conversion module 102 just outputs the test current. Ensuring that the super capacitor 1016 discharges to release the analog electrical signal for transmission to the conversion module 102 only in the event of a power outage in the second loop.

The controller 103 being configured to parse the coded combination of digital signals according to a predetermined mapping relationship to determine the status of the skate further comprises the controller being configured to:

after receiving the second level output by at least one of the first contact piece 1011, the second contact piece 1012 and the third contact piece 1013, receiving the second level in the reverse direction within a preset time, and determining that the corresponding first contact piece 1011, the second contact piece 1012 or the third contact piece 1013 is damaged;

when the first contact piece 1011, the second contact piece 1012, or the third contact piece 1013 is damaged, the transmission of the test current is stopped, and an alarm is given.

It is understood that the digital signals received by the controller 103 are divided into: 111 (no-contact state), 011 (normal anti-slide state), 001 (anti-slide close state) and 000 (dangerous state) and a second level, and then receiving the reversed second level (touch sheet damage), corresponding measures can be taken to ensure the safety of the rail transit after the stop through various states judged by the controller 103. And the discharge characteristic of the super capacitor 1016 is matched with the connection relation of the touch sheet 101a, so that the touch sheet 101a can be known at the first time when being damaged, and the use reliability of the state detection device 100 is improved.
