Background

At present, in the field of touch technology, a common infrared transmitter often causes a problem of abnormal transmission due to damage of a part of infrared transmitting tubes, and an infrared receiver often causes a problem of abnormal reception due to damage of a part of infrared receiving tubes, thereby causing low touch test data or no touch on the local part. Meanwhile, if damaged lamp tubes exist in the infrared transmitting tube and the infrared receiving tube, the touch device needs to be disassembled for maintenance, so that the maintenance cost is high, and the touch device is particularly easy to damage secondarily due to disassembly for maintenance.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed description will be omitted.

Although relative terms, such as "upper" and "lower," may be used in this specification to describe one element of an icon relative to another, these terms are used in this specification for convenience only, e.g., in accordance with the orientation of the examples described in the figures. It will be appreciated that if the device of the icon were turned upside down, the element described as "upper" would become the element "lower". When a structure is "on" another structure, it may mean that the structure is integrally formed with the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure via another structure.

The terms "a," "an," "the," "said" are used to indicate the presence of one or more elements/components/etc.; the terms "comprising" and "having" are intended to be inclusive and mean that there may be additional elements/components/etc. other than the listed elements/components/etc.; the terms "first" and "second", etc. are used merely as labels, and are not limiting on the number of their objects.

As shown in fig. 1 to 2, the present disclosure firstly provides an infrared emitter 1, in which each infrared emitting tube in the infrared emitter 1 can be independently controlled. Therefore, the infrared emitter 1 can enable all the infrared emission tubes to work alternatively, and when all the infrared emission tubes work, the sensitivity of the infrared emitter 1 can be increased; when the infrared emission tubes are alternately operated, in the case where one of the infrared emission tubes is damaged, the other infrared emission tube can be used instead of the operation thereof. Therefore, the infrared emitter 1 provided by the disclosure does not need to be dismantled and maintained when the infrared emitting tube is damaged, and only the replaced infrared emitting tube needs to be opened. Furthermore, compared with the prior art, the method and the device can reduce a large amount of overhaul cost and can prevent the problem of secondary damage to the machine caused by dismantling the machine.

Specifically, as shown in fig. 1 to 6, the infrared emitter 1 provided by the present disclosure may include: a first infrared emission tube 11, a second infrared emission tube 12 and a first control assembly.

Wherein the first infrared emission tube 11 may also have two ends, i.e. a first end and a second end. The first terminal may be a positive terminal, and the second terminal may be a negative terminal.

The first end of the first infrared-emitting tube 11 may be connected to a first voltage 15, and the first voltage 15 may be a positive voltage. The first infrared-emitting tube 11 may be an infrared-emitting lamp, which may emit infrared rays. The infrared emitter 1 provided by the present disclosure may have a plurality of first infrared emitting tubes 11, and the plurality of infrared emitting tubes may be arranged in parallel, but is not limited thereto, and the first infrared emitting tubes 11 may also be arranged in other manners, such as circular, etc., which is within the protection scope of the present disclosure.

Further, the second infrared-emitting tube 12 may have two ends, i.e., a first end and a second end. The first terminal may be a negative terminal, and the second terminal may be a positive terminal.

The first terminal of the second infrared-emitting tube 12 may be connected to a second voltage 16, the second voltage 16 may be a negative voltage, and the negative voltage may be a ground voltage. The first infrared-emitting tube 11 may also be an infrared-emitting lamp that can emit infrared rays. The infrared emitter 1 provided by the present disclosure may have a plurality of second infrared emission tubes 12, and the plurality of second infrared emission tubes 12 may be arranged in parallel, but is not limited thereto, and the second infrared emission tubes 12 may also be arranged in other manners, such as circular, etc., which is within the protection scope of the present disclosure.

In an embodiment of the present disclosure, as shown in fig. 1 to 2, the infrared emitter 1 may further include a first circuit board 19, and the first circuit board 19 may be a printed circuit board, but is not limited thereto, and may also be other types of circuit boards, which may be selected according to actual needs. The first infrared emission tubes 11 may be disposed on the first circuit board 19, and the first infrared emission tubes 11 may be sequentially arranged along an extending direction of the first circuit board 19. The first circuit board 19 may be rectangular, but is not limited thereto, and may also be in other shapes, which may be selected according to actual needs, and the disclosure is not repeated herein.

Further, the first circuit board 19 may have a first region 191 and a second region 192. Here, a first distance may be provided between two adjacent first infrared emission tubes 11 in the first region 191, and a second distance may be provided between two adjacent first infrared emission tubes 11 in the second region 192. The first interval may be greater than the second interval, and at least one second infrared emission tube 12 may be disposed between adjacent two first infrared emission tubes 11 in the first region 191. It will be appreciated that the first spacing needs to be at least greater than the size of one of the second infrared-emitting tubes 12.

In one embodiment of the present disclosure, on the first circuit board 19, two second regions 192 may be respectively disposed at two ends of the first region 191, that is: the first region 191 may be located at the center of the first circuit board 19, and the second regions 192 may be located at both ends of the first circuit board 19. By so arranging, the density of the first infrared emission tubes 11 at the center of the first circuit board 19 can be made smaller than the density of the first infrared emission tubes 11 at the edge of the first circuit board 19. Thus, the present disclosure can save cost and reduce power consumption while satisfying infrared emission accuracy by this arrangement.

Further, the first interval between adjacent two first infrared-emitting tubes 11 located in the first region 191 may gradually increase from the center of the first circuit board 19 to both ends of the first circuit board 19. It is understood that the first distance between two first infrared-emitting tubes 11 closer to the center of the first circuit board 19 is larger, and the first distance between two first infrared-emitting tubes 11 farther from the center of the first circuit board 19 is smaller. With this arrangement, the accuracy of infrared emission can be further improved.

As shown in fig. 3 to 4, the first control assembly may include a first switch controller 13 and a first signal controller 14. Wherein the first switch controller 13 may be connected to the second end of the first infrared emission tube 11 and the second end of the second infrared emission tube 12. The first signal controller 14 may be connected to the first switch controller 13, and the first signal controller 14 may input a first control signal to the first switch controller 13, the first switch controller 13 may output a first switch signal or a second switch signal to the first infrared transmitting tube 11 and the second infrared generating tube, respectively, according to the first control signal, and the first infrared transmitting tube 11 and the second infrared transmitting tube 12 may be turned on according to the first switch signal and may be turned off according to the second switch signal.

Wherein the first switching signal may be a high level signal, and when the high level signal is inputted, the first switching controller 13 is in an open state so that at least one of the first infrared transmitting tube 11 and the second infrared transmitting tube 12 may be opened. The second switching signal may be a low level signal, and when the low level signal is input, the first switching controller 13 is in an off state, and both the first infrared transmitting tube 11 and the second infrared transmitting tube 12 are in an off state. Accordingly, the present disclosure can independently control the turn-on and turn-off of the respective infrared emission tubes by the first switch controller 13 and the first signal controller 14, and can control the first infrared emission tube 11 and the second infrared emission tube 12 to be all turned on and off and the alternate operation of the first infrared emission tube 11 and the second infrared emission tube 12.

In one embodiment of the present disclosure, the first signal controller 14 may include a first signal output terminal 141, and the first switch controller 13 may include a first switch control component. The first switch control assembly may include: a first switching control element 131, a first not gate circuit 132, a first or gate circuit 133, and a second switching control element 134.

Wherein the first terminal of the first switching control element 131 may be connected to the first signal output terminal 141, that is: the first terminal of the first switching element may be a control terminal. A second terminal of the first switching control element 131 may be connected to the second terminal of the first infrared-emitting tube 11 and the third voltage 17, and the second terminal of the first switching control element 131 may be capable of outputting a first switching signal or a second switching signal. When the first voltage 15 is a positive voltage, the third voltage 17 may be a negative voltage, which may be a ground voltage.

The input terminal of the first not gate circuit 132 may be connected to a first signal input terminal, and the first control signal input from the first signal input terminal can be converted into an opposite signal output by the first not gate circuit 132, for example: when the first control signal inputted from the first signal input terminal is a high level signal, the output terminal of the first not gate circuit 132 outputs a low level signal, and vice versa.

A first input terminal of the first or gate circuit 133 may be connected to a second terminal of the first switch control element 131, and a second input terminal of the first or gate circuit 133 may be connected to an output terminal of the first not gate circuit 132. The first or gate 133 can output a signal by an or operation. For example: when the first input terminal and the second input terminal both input a high level signal, the first or gate circuit 133 outputs a high level signal; the first or gate circuit 133 outputs a high level signal when the first input terminal and the second input terminal input a high level signal and a low level signal, respectively; when the first input terminal and the second input terminal both input a low level signal, the first or gate circuit 133 outputs a low level signal.

A first terminal of the second switching control element 134 may be connected to the output terminal of the first or gate circuit 133, and a second terminal of the second switching control element 134 may be connected to the second terminal of the second ir transmitting tube 12 and the fourth voltage 18. The second terminal of the second switch control element 134 can output the first switch signal or the second switch signal. When the second voltage 16 is a negative voltage, the fourth voltage 18 may be a positive voltage.

It should be noted that the first switching control element 131 and the second switching control element are opened in opposite ways, for example: the first terminal of the first switch control element 131 may be turned on by inputting a high level signal, and the first terminal of the second switch control element 134 may be turned on by inputting a low level signal.

For example, the first switching control element 131 may be a first N-type field effect transistor. The control terminal of the first N-type fet may be connected to the first signal input terminal, the output terminal of the first N-type fet may be connected to the second terminal of the first ir-emitting diode 11, and the input terminal of the first N-type fet may be connected to the third voltage 17. But not limited thereto, the output terminal of the first N-type fet may be connected to the third voltage 17, and the input terminal of the first N-type fet may be connected to the second terminal of the first ir-emitting tube 11, which may be selected according to actual needs. It should be understood that the control terminal of the first N-type fet may be the first terminal of the first switching control element 131, and the output terminal and the input terminal of the first N-type fet may be the second terminal of the first switching control element 131.

The first input terminal of the first or gate circuit 133 may be connected to the input terminal of the first N-type fet, but is not limited thereto, and the first input terminal of the first or gate circuit 133 may also be connected to the output terminal of the first N-type fet, which is also within the scope of the present disclosure.

The second switching control element 134 may be a first P-type fet. The control terminal of the first pfet may be connected to the output terminal of the first or gate 133, the output terminal of the first pfet may be connected to the second terminal of the second ir transmitting tube 12, and the input terminal of the first pfet may be connected to the fourth voltage 18. But not limited thereto, the output terminal of the first pfet may be connected to the fourth voltage 18, and the input terminal of the first pfet may be connected to the second terminal of the second ir emitting tube 12, which may be selected according to actual needs. Namely: it should be understood that the control terminal of the first pfet may be the first terminal of the second switch control element 134, and the output terminal and the input terminal of the first pfet may be the second terminal of the second switch control element 134.

When the first signal controller 14 of the present disclosure outputs a high level signal through the first signal output terminal 141, the control terminal of the first N-type fet is at a high level, and then the first N-type fet is turned on, and the first infrared emission tube 11 is turned on. At this time, the first not gate circuit 132 outputs a low level signal, the input terminal and the output terminal of the first N-type fet are at a high level, the first input terminal of the first or gate circuit 133 inputs a high level signal, the second input terminal of the first or gate circuit 133 inputs a low level signal, and the output terminal of the first or gate circuit 133 outputs a high level signal. When the control terminal of the first P-type fet receives the high level signal, the first P-type fet is turned off, and the second ir transmitting tube 12 is not turned on at this time.

When the first signal controller 14 of the present disclosure outputs a high level signal through the first signal output terminal 141 and the first infrared transmitting tube 11 is damaged, the control terminal of the first N-type field effect tube is at a high level, then the first N-type field effect tube is opened, and at this time, because the first infrared transmitting tube 11 is damaged, then the first infrared transmitting tube 11 cannot be opened. At this time, the first not gate circuit 132 outputs a low level signal, the input terminal and the output terminal of the first N-type fet are at a low level, the first input terminal of the first or gate circuit 133 inputs the low level signal, the second input terminal of the first or gate circuit 133 inputs the low level signal, and the output terminal of the first or gate circuit 133 outputs the low level signal. When the control terminal of the first P-type fet receives a low level signal, the first P-type fet is turned on, and at this time, the second ir transmitting tube 12 is turned on, so that the second ir transmitting tube 12 is used instead of the first ir transmitting tube 11 to perform work. Therefore, the problem that the first infrared transmitting tube 11 needs to be disassembled to overhaul the first infrared transmitting tube when the first infrared transmitting tube is damaged can be avoided, a large amount of disassembling cost is saved, and the machine can be protected from secondary damage.

When the first signal controller 14 of the present disclosure outputs a low level signal through the first signal output terminal 141, the control terminal of the first N-type fet is at a low level, and then the first N-type fet is turned off, and the first infrared emission tube 11 is turned off. At this time, the first not gate circuit 132 outputs a high level signal, the input terminal and the output terminal of the first N-type fet are at a low level, the first input terminal of the first or gate circuit 133 inputs a low level signal, the second input terminal of the first or gate circuit 133 inputs a high level signal, and the output terminal of the first or gate circuit 133 outputs a high level signal. When the control end of the first P-type field effect transistor receives a high level signal, the first P-type field effect transistor is turned off, and at this time, the second infrared emission tube 12 is also not turned on. The state of the infrared transmitter 1 at this time may be a normal scanning state which does not affect the subsequent opening of the first infrared transmitting tube 11 and the second infrared transmitting tube 12.

Further, the first switch control assembly may further include: a first current limiting resistor 135 and a second current limiting resistor 136. One end of the first current limiting resistor 135 may be connected to the first input terminal of the N-type fet, and the other end of the first current limiting resistor 135 may be connected to the third voltage 17. The first infrared transmitting tube 11 can be prevented from short-circuiting by providing the first current limiting resistor 135.

One end of the second current limiting resistor 136 may be connected to a first end of the second infrared emitting tube 12, and the other end may be connected to the second voltage 16. The second infrared transmitting tube 12 can be prevented from short-circuiting by providing the second current limiting resistor 136.

Therefore, this disclosure can control all first infrared emission tubes 11 and second infrared emission tubes 12 respectively through setting up a plurality of first on-off control assembly through a plurality of first on-off control assembly, and then makes this disclosure more accurate to all first infrared emission tubes 11 and second infrared emission tubes 12's control.

In one embodiment of the present disclosure, as shown in fig. 5, the first switch controller 13 may further include: a first processor 137 and a second processor 138, and the first processor 137 and the second processor 138 may be plural. The first processor 137 may include a first processor 137 input terminal and a plurality of first processor 137 output terminals, each of the first processor 137 output terminals may be connected to a first terminal of a first infrared emitting tube 11, and the first processor 137 input terminal may be connected to the first voltage 15. The first processor 137 may be a decoder, for example: the first processor 137 may be a decoder model 74HC138 having 8 outputs. Thus, the decoder can simultaneously control the 8 first infrared-emitting tubes 11, respectively.

The second processor 138 may include a second processor 138 input and a plurality of second processor 138 outputs, each of the second processor 138 outputs may be coupled to a first terminal of a second infrared-emitting tube 12, and the second processor 138 input may be coupled to the second voltage 16. The second processor 138 may also be a decoder, for example: the second processor 138 may be a decoder model 74HC138 having 8 outputs. Thus, the decoder can simultaneously control 8 second infrared emission tubes 12, respectively.

Thus, the present disclosure can greatly reduce the number of the first switch controllers 13 by providing the first processor 137 and the second processor 138, thereby simplifying the arrangement of the circuit.

In an embodiment of the present disclosure, the first control component may also be disposed on the first circuit board 19, but is not limited thereto, and the first control component may also be disposed at other positions, and may be disposed according to actual needs, which is within the protection scope of the present disclosure.

A first terminal of each third switching control element 139 may be connected to a second signal output terminal 142, a second terminal of each third switching control element 139 may be connected to a second terminal of one first infrared transmitting tube 11, and the third switching control element 139 may be capable of outputting the first switching signal or the second switching signal. The first terminal of the third control element may be a control terminal, and the second terminal may be an output terminal. Thus, the present disclosure can control each of the first infrared emission tubes 11 by providing the plurality of third switch control elements 139, respectively, and different switch signals can be input to each of the first infrared emission tubes 11, respectively, to control the state of each of the first infrared emission tubes 11, respectively. For example: when the first second signal output terminal 142 inputs a high level signal to the first third switching control element 139 and the second signal output terminal 142 inputs a low level signal to the second third switching control element 139, the first infrared transmitting tube 11 is turned on and the second first infrared transmitting tube 11 is turned off.

A first terminal of each of the fourth switch control elements 140 may be connected to a third signal output terminal 143, a second terminal of each of the fourth switch control elements 140 may be connected to a second terminal of one of the second infrared transmitting tubes 12, and the fourth switch control elements 140 may be capable of outputting the first switch signal or the second switch signal.

Thus, the present disclosure can control each second infrared transmitting tube 12 by providing a plurality of fourth switch control elements 140, and different switch signals can be input to each second infrared transmitting tube 12 to control the state of each second infrared transmitting tube 12. For example: when the first third signal output terminal 143 inputs a high level signal to the first fourth switch control element 140, and the second third signal output terminal 143 inputs a low level signal to the second fourth switch control element 140, the first second infrared transmitting tube 12 is turned on, and the second infrared transmitting tube 12 is turned off.

When the second signal output terminal 142 and the third signal output terminal 143 both output high level signals, the first infrared transmitting tube 11 and the second infrared transmitting tube 12 may be fully opened, and at this time, the accuracy of the infrared transmitter 1 may be increased.

An output terminal of the first controller 145 may be connected to a first signal input terminal, and a feedback terminal of the first controller 145 may be connected to a signal feedback terminal of the first driver 144. An input of the first amplifier 146 may be connected to the first infrared receiver 2, an output of the first amplifier 146 is connected to the second signal input for amplifying the signal output by the first infrared receiver 2 and transferring to the first driver 144, and the first driver 144 may feed the signal back to the first controller 145, thereby controlling the output of the first or second control signal through the first controller 145. It can be understood that: the first controller 145 may be software, and when the software receives a signal that one of the first infrared receiving tubes 21 is damaged, the software controls the driver to open the second infrared receiving tube 22 adjacent to the first infrared receiving tube 21 instead of the damaged first infrared receiving tube 21.

In an embodiment of the present disclosure, the third switch control element 139, the fourth switch control element 140, the first driver 144, the first controller 145 and the first amplifier 146 may be disposed on the first circuit board 19, but are not limited thereto, and may be disposed elsewhere, and may be disposed according to actual needs.

As shown in fig. 7 to 8, a second aspect of the present disclosure provides an infrared receiver 2 in which each infrared receiving tube in the infrared receiver 2 can be independently controlled. Therefore, the infrared receiver 2 can make the infrared receiving tubes work all and alternately, and when the infrared receiving tubes all work, the sensitivity of the infrared receiver 2 can be increased; when the infrared receiving tubes work alternately, under the condition that one infrared receiving tube is damaged, the other infrared receiving tube can be used for replacing the work. Therefore, the infrared receiver 2 provided by the present disclosure does not need to be dismantled and maintained when the infrared receiving tube is damaged, and only the replaced infrared receiving tube needs to be opened. Furthermore, compared with the prior art, the method and the device can reduce a large amount of overhaul cost and can prevent the problem of secondary damage to the machine caused by dismantling the machine.

Specifically, as shown in fig. 7 to 12, the infrared receiver 2 provided by the present disclosure may include: a first infrared receiving tube 21, a second infrared receiving tube 22 and a second control assembly.

Here, the first infrared receiving tube 21 may have two ends, i.e., a first end and a second end. The first terminal may be a positive terminal, and the second terminal may be a negative terminal.

The first terminal of the first infrared receiving tube 21 may be connected to a fifth voltage 25, and the fifth voltage 25 may be a positive voltage. The first infrared receiving tube 21 may be an infrared receiving lamp that can receive infrared rays. The infrared receiver 2 provided by the present disclosure may have a plurality of first infrared receiving tubes 21, and the plurality of infrared receiving tubes may be arranged in parallel, but is not limited thereto, and the first infrared receiving tubes 21 may also be arranged in other manners, such as a circle, and the like, and this is within the protection scope of the present disclosure.

Further, the second infrared receiving tube 22 may have two ends, i.e., a first end and a second end. The first terminal may be a negative terminal, and the second terminal may be a positive terminal.

The first terminal of the second infrared receiving tube 22 may be connected to a sixth voltage 26, and the sixth voltage 26 may be a negative voltage, which may be a ground voltage. The first infrared receiving tube 21 may also be an infrared receiving lamp, which may emit infrared rays. The infrared receiver 2 provided by the present disclosure may have a plurality of second infrared receiving tubes 22, and the plurality of second infrared receiving tubes 22 may be arranged in parallel, but is not limited thereto, and the second infrared receiving tubes 22 may also be arranged in other manners, such as circular, etc., which is within the protection scope of the present disclosure.

In an embodiment of the present disclosure, as shown in fig. 1 to 2, the infrared receiver 2 may further include a second circuit board 29, and the second circuit board 29 may be a printed circuit board, but is not limited thereto, and may also be other types of circuit boards, which may be selected according to actual needs. The first infrared receiving tubes 21 may be disposed on the second circuit board 29, and the first infrared receiving tubes 21 may be sequentially arranged along the extending direction of the second circuit board 29. The second circuit board 29 may be rectangular, but is not limited thereto, and may also be in other shapes, which may be selected according to actual needs, and the disclosure is not repeated herein.

Further, the second circuit board 29 may have a third region 291 and a fourth region 292. Here, a third distance may be provided between two adjacent first infrared receiving tubes 21 in the third region 291, and a fourth distance may be provided between two adjacent first infrared receiving tubes 21 in the fourth region 292. The third pitch may be larger than the fourth pitch, and at least one second infrared receiving tube 22 may be disposed between adjacent two first infrared receiving tubes 21 in the third region 291. It will be appreciated that the third distance needs to be at least greater than the size of one second infrared receiving tube 22.

In one embodiment of the present disclosure, on the second circuit board 29, two ends of the third region 291 may be respectively provided with a fourth region 292, that is: the third region 291 may be located at the center of the circuit board and the fourth regions 292 may be located at both ends of the second circuit board 29. By so doing, it is possible to make the density of the first infrared receiving tubes 21 at the center of the second circuit board 29 smaller than the density of the first infrared receiving tubes 21 at the edge of the circuit board. Therefore, the cost is saved and the power consumption is reduced under the condition that the infrared receiving precision is met through the arrangement.

Further, the third pitch between adjacent two first infrared receiving tubes 21 located in the third area 291 may gradually increase from the center of the second circuit board 29 to both ends of the second circuit board 29. It is understood that the third distance between the two first infrared receiving tubes 21 closer to the center of the second circuit board 29 is larger, and the third distance between the two first infrared receiving tubes 21 farther from the center of the second circuit board 29 is smaller. With this arrangement, the accuracy of infrared reception can be further improved.

As shown in fig. 9 to 10, the second control assembly may include: a second switch controller 23 and a second signal controller 24. Wherein the second switch controller 23 may be connected to the second end of the first infrared receiving tube 21 and the second end of the second infrared receiving tube 22.

Wherein the third switching signal may be a high level signal, and when the high level signal is inputted, the second switching controller 23 is in an open state so that at least one of the first infrared receiving tube 21 and the second infrared receiving tube 22 may be opened. The fourth switching signal may be a low level signal, and when the low level signal is input, the second switching controller 23 is in an off state, and both the first infrared receiving tube 21 and the second infrared receiving tube 22 are in the off state. Therefore, the present disclosure can independently control the turn-on and turn-off of the respective infrared receiving tubes by the second switch controller 23 and the second signal controller 24, and can control the first infrared receiving tube 21 and the second infrared receiving tube 22 to be turned on and off in their entirety and the first infrared receiving tube 21 and the second infrared receiving tube 22 to be operated alternately.

When the fifth voltage 25 is a positive voltage, the seventh voltage 27 may be a negative voltage, which may be a ground voltage.

The input terminal of the second not gate circuit 232 may be connected to a fourth signal input terminal, and the second control signal input from the fourth signal input terminal can be converted into an opposite signal output by the second not gate circuit 232, for example: when the second control signal inputted from the fourth signal input terminal is a high level signal, the output terminal of the first not gate circuit 132 outputs a low level signal, and vice versa.

A first input terminal of the second or gate circuit 233 may be connected to a second terminal of the fifth switching control element 231, and a second input terminal of the second or gate circuit 233 may be connected to an output terminal of the second not gate circuit 232. The second or gate circuit 233 can output a signal by an or operation. For example: when the first input terminal and the second input terminal both input a high level signal, the second or gate circuit 233 outputs a high level signal; when the first input terminal and the second input terminal input a high level signal and a low level signal, respectively, the second or gate circuit 233 outputs a high level signal; when a low level signal is input to both the first input terminal and the second input terminal, the second or gate circuit 233 outputs a low level signal.

When the sixth voltage 26 is a negative voltage, the eighth voltage 28 may be a positive voltage.

It should be noted that the opening modes of the fifth switching control element 231 and the sixth switching control element are opposite, for example: a first terminal of the fifth switching control element 231 may be turned on by inputting a high level signal, and a first terminal of the sixth switching control element 234 may be turned on by inputting a low level signal.

For example, the fifth switching control element 231 may be a second N-type fet. The control terminal of the second N-type field effect transistor may be connected to the fourth signal input terminal, the output terminal of the second N-type field effect transistor may be connected to the second terminal of the first infrared receiving tube 21, and the input terminal of the second N-type field effect transistor may be connected to the seventh voltage 27. But not limited thereto, the output terminal of the second N-type fet may be connected to the seventh voltage 27, and the input terminal of the second N-type fet may be connected to the second terminal of the first infrared receiving tube 21, which may be selected according to actual needs. It should be understood that the control terminal of the second N-type fet may be the first terminal of the fifth switching control element 231, and the output terminal and the input terminal of the second N-type fet may be the second terminal of the fifth switching control element 231.

When the second signal controller 24 of the present disclosure outputs a high level signal through the fourth signal output terminal 241 and the first infrared receiving tube 21 is damaged, the control terminal of the second N-type field effect tube is at a high level, the second N-type field effect tube is turned on, and at this time, the first infrared receiving tube 21 cannot be turned on because the first infrared receiving tube 21 is damaged. At this time, the second not gate circuit 232 outputs a low level signal, the input end and the output end of the second N-type fet are at a low level, the first input end of the second or gate circuit 233 inputs the low level signal, the second input end of the second or gate circuit 233 inputs the low level signal, and the output end of the second or gate circuit 233 outputs the low level signal.

Therefore, the problem that the first infrared receiving tube 21 needs to be disassembled to overhaul the first infrared receiving tube when the first infrared receiving tube is damaged can be avoided, a large amount of disassembly cost is saved, and the machine can be protected from secondary damage.

When the second signal controller 24 of the present disclosure outputs a low level signal through the fourth signal output terminal 241, and the control terminal of the second N-type fet is at a low level, the second N-type fet is turned off, and the second infrared receiving tube 22 is turned off. At this time, the second not gate circuit 232 outputs a high level signal, the input end and the output end of the second N-type fet are at a low level, the first input end of the second or gate circuit 233 inputs a low level signal, the second input end of the second or gate circuit 233 inputs a high level signal, and the output end of the second or gate circuit 233 outputs a high level signal.

The state of the infrared receiver 2 at this time may be a normal scanning state which does not affect the subsequent opening of the first infrared receiving tube 21 and the second infrared receiving tube 22.

Further, the second switch control assembly may further include: a third current limiting resistor 235 and a fourth current limiting resistor 236. One end of the third current limiting resistor 235 may be connected to the second input terminal of the N-type fet, and the other end of the third current limiting resistor 235 may be connected to the seventh voltage 27.

Therefore, this disclosure can control all the first infrared receiving tubes 21 and the second infrared receiving tubes 22 respectively through setting up a plurality of second switch control assemblies, and then make this disclosure more accurate to all the first infrared receiving tubes 21 and the control of second infrared receiving tubes 22.

For example: when the first fifth signal output terminal 242 inputs a high level signal to the first seventh switch control element 239 and the second fifth signal output terminal 242 inputs a low level signal to the second seventh switch control element 239, the first infrared receiving tube 21 is turned on and the second first infrared receiving tube 21 is turned off.
