As shown in fig. 1-2, the present disclosure first provides an infrared emitter 1, each of which infrared emitter 1 is capable of independent control. Thus, the infrared emitter 1 can enable all and alternate operation of the respective infrared emitting tubes, and the sensitivity of the infrared emitter 1 can be increased when all of the respective infrared emitting tubes are operated; when the infrared transmitting tubes work alternately, one infrared transmitting tube can be used for replacing the other infrared transmitting tube to work under the condition that the other infrared transmitting tube is damaged. Therefore, when the infrared transmitting tube is damaged, the infrared transmitter 1 does not need to be disassembled for maintenance, and only needs to be started for replacing the infrared transmitting tube. Furthermore, compared to the prior art, the present disclosure can reduce a large amount of maintenance costs, and can prevent the problem of secondary damage to the machine by disassembling the machine.

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

The first infrared transmitting tube 11 may also have two ends, namely a first end and a second end. The first end may be a positive end and the second end may be a negative end.

A first terminal 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 emission tube 11 may be an infrared emission lamp, which emits infrared rays. The infrared emitter 1 provided in 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 be arranged in other manners, such as a circle, etc., which is within the scope of the present disclosure.

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

The first end of the second infrared emitting tube 12 may be connected to a second voltage 16, and the second voltage 16 may be a negative voltage, and the negative voltage may be a ground voltage. The first infrared transmitting tube 11 may also be an infrared transmitting lamp, which emits infrared light. The infrared emitter 1 provided in the present disclosure may have a plurality of second infrared emitting tubes 12, and the plurality of second infrared emitting tubes 12 may be arranged in parallel, but not limited thereto, and the second infrared emitting tubes 12 may be arranged in other manners, such as a circle, etc., which is within the scope of the present disclosure.

In one embodiment of the present disclosure, as shown in fig. 1-2, the infrared emitter 1 may further include a first circuit board 19, where the first circuit board 19 may be a printed circuit board, but is not limited thereto, and may be another type of circuit board, 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 the extending direction of the first circuit board 19. The first circuit board 19 may be rectangular, but is not limited thereto, and may be other shapes, and may be selected according to actual needs, which will not be described herein.

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

In one embodiment of the present disclosure, on the first circuit board 19, two ends of the first region 191 may be provided with one second region 192, respectively, that is: the first region 191 may be located at the center of the first circuit board 19 and the second region 192 may be located at both ends of the first circuit board 19. By this arrangement, 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 edges of the first circuit board 19. Thus, the present disclosure can save costs and reduce power consumption while satisfying infrared emission accuracy by this arrangement.

Further, the first spacing between two adjacent first infrared emission tubes 11 located in the first region 191 may gradually increase from the center of the first circuit board 19 toward both ends of the first circuit board 19. It will be appreciated that the first distance between two first infrared transmitting tubes 11 is greater nearer the center of the first circuit board 19 and the first distance between two first infrared transmitting tubes 11 is smaller farther from the center of the first circuit board 19. 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, first switch controller 13 can be connected with the second end of first infrared transmitting tube 11 and the second end of second infrared transmitting 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, and the first switch controller 13 may output a first switch signal or a second switch signal to the first infrared emission tube 11 and the second infrared emission tube according to the first control signal, and the first infrared emission tube 11 and the second infrared emission tube 12 may be turned on according to the first switch signal and may be turned off according to the second switch signal.

The first switch signal may be a high level signal, and when the high level signal is input, the first switch controller 13 is in an on state, so that at least one of the first infrared transmitting tube 11 and the second infrared transmitting tube 12 may be turned on. The second switch signal may be a low level signal, and when the low level signal is input, the first switch controller 13 is in an off state, and the first infrared emission tube 11 and the second infrared emission tube 12 are both in an off state. Accordingly, the present disclosure can independently control the turning on and off of the respective infrared emission tubes through the first switch controller 13 and the first signal controller 14, and can control the turning on and off of the first infrared emission tube 11 and the second infrared emission tube 12 in their entirety, and the alternating 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 141 and the first switch controller 13 may include a first switch control component. The first switch control assembly may include: a first switch control element 131, a first not gate 132, a first or gate 133, and a second switch control element 134.

Wherein, the first end of the first switch control element 131 may be connected to the first signal output terminal 141, namely: 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 emission tube 11 and the third voltage 17, and the second terminal of the first switching control element 131 may be capable of outputting the first switching signal or the 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 132 may be connected to the first signal output terminal 141, and the first control signal input from the first signal output terminal 141 may be converted into an opposite signal output by the first not gate 132, for example: when the first control signal input from the first signal output terminal 141 is a high level signal, the output terminal of the first not gate 132 outputs a low level signal, and vice versa.

A first input terminal of the first or circuit 133 may be connected to the second terminal of the first switch control element 131, and a second input terminal of the first or circuit 133 may be connected to an output terminal of the first not circuit 132. The first or circuit 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; when the first input terminal and the second input terminal input a high level signal and a low level signal, respectively, the first or gate 133 outputs a high level signal; 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 switch control element 134 may be connected to the output terminal of the first or gate 133, and a second terminal of the second switch control element 134 may be connected to the second terminal of the second infrared emission tube 12 and the fourth voltage 18. The second terminal of the second switching control element 134 is capable of outputting either the first switching signal or the second switching signal. When the second voltage 16 is a negative voltage, the fourth voltage 18 may be a positive voltage.

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

For example, the first switch control element 131 may be a first N-type field effect transistor. The control end of the first N-type field effect transistor may be connected to the first signal output end 141, the output end of the first N-type field effect transistor may be connected to the second end of the first infrared emission tube 11, and the input end of the first N-type field effect transistor may be connected to the third voltage 17. But not limited to this, the output end of the first N-type field effect transistor may be connected to the third voltage 17, and the input end of the first N-type field effect transistor may be connected to the second end of the first infrared emission tube 11, and may be selected according to actual needs. It should be understood that the control terminal of the first N-type field effect transistor may be the first terminal of the first switch control element 131, and the output terminal and the input terminal of the first N-type field effect transistor may be the second terminal of the first switch control element 131.

It is within the scope of the disclosure that the first input terminal of the first or gate 133 may be connected to the input terminal of the first N-type field effect transistor, but not limited thereto, and the first input terminal of the first or gate 133 may also be connected to the output terminal of the first N-type field effect transistor.

The second switch control element 134 may be a first P-type field effect transistor. The control terminal of the first P-type field effect transistor may be connected to the output terminal of the first or gate 133, the output terminal of the first P-type field effect transistor may be connected to the second terminal of the second infrared emitting transistor 12, and the input terminal of the first P-type field effect transistor may be connected to the fourth voltage 18. But not limited thereto, the output terminal of the first P-type field effect transistor may be connected to the fourth voltage 18, and the input terminal of the first P-type field effect transistor may be connected to the second terminal of the second infrared emitting transistor 12, and may be selected according to actual needs. Namely: it should be appreciated that the control terminal of the first P-type fet may be the first terminal of the second switch control element 134 described above, and the output terminal and the input terminal of the first P-type fet may be the second terminal of the second switch control element 134 described above.

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 field effect transistor is at a high level, and then the first N-type field effect transistor is turned on, and the first infrared emission transistor 11 is turned on. At this time, the first not gate 132 outputs a low level signal, the input terminal and the output terminal of the first N-type field effect transistor are high level, at this time, the first input terminal of the first or gate 133 inputs a high level signal, the second input terminal of the first or gate 133 inputs a low level signal, and the output terminal of the first or gate 133 outputs a high level signal. When the control end of the first P-type field effect transistor receives the high level signal, the first P-type field effect transistor is turned off, and the second infrared emission transistor 12 is not turned on.

When the first signal controller 14 of the present disclosure outputs a high level signal through the first signal output end 141 and the first infrared transmitting tube 11 is damaged, the control end of the first N-type field effect tube is at a high level, and then the first N-type field effect tube is turned on, and at this time, the first infrared transmitting tube 11 cannot be turned on due to the damage of the first infrared transmitting tube 11. At this time, the first not gate 132 outputs a low level signal, the input terminal and the output terminal of the first N-type field effect transistor are low level, at this time, the first input terminal of the first or gate 133 inputs a low level signal, the second input terminal of the first or gate 133 inputs a low level signal, and the output terminal of the first or gate 133 outputs a low level signal. When the control end of the first P-type field effect tube receives a low-level signal, the first P-type field effect tube is turned on, and at the moment, the second infrared emission tube 12 is turned on, so that the second infrared emission tube 12 is used for replacing the first infrared emission tube 11 to work. Therefore, the problem that the machine needs to be disassembled to overhaul the first infrared transmitting tube 11 when the first infrared transmitting tube is damaged can be avoided, a large amount of machine 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 field effect transistor is at a low level, and the first N-type field effect transistor is turned off, and the first infrared emission transistor 11 is turned off. At this time, the first not gate 132 outputs a high level signal, the input terminal and the output terminal of the first N-type field effect transistor are low level, at this time, the first input terminal of the first or gate 133 inputs a low level signal, the second input terminal of the first or gate 133 inputs a high level signal, and the output terminal of the first or gate 133 outputs a high level signal. When the control end of the first P-type field effect transistor receives the high level signal, the first P-type field effect transistor is turned off, and the second infrared emission transistor 12 is not turned on. The state of the infrared emitter 1 can be a normal scanning state, which does not affect the subsequent opening of the first infrared emission tube 11 and the second infrared emission 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 N-type fet input terminal, and the other end of the first current limiting resistor 135 may be connected to the third voltage 17. By providing first current limiting resistor 135, a short circuit of first infrared transmitting tube 11 can be prevented.

One end of second current limiting resistor 136 may be connected to a first end of second infrared emitting tube 12 and the other end may be connected to second voltage 16. By providing second current limiting resistor 136, a short circuit of second infrared emitting tube 12 can be prevented.

Therefore, the control of the first infrared transmitting tube 11 and the second infrared transmitting tube 12 is more accurate through setting up a plurality of first switch control components, and can be controlled through a plurality of first switch control components respectively.

In one embodiment of the present disclosure, as shown in fig. 5, the first switch controller 13 may further include: the first processor 137 and the second processor 138 may be plural. The first processor 137 may include a first processor 137 input end and a plurality of first processor 137 output ends, where each first processor 137 output end may be connected to a first end of a first infrared emission tube 11, and an input end of the first processor 137 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 model 74HC138 decoder having 8 outputs. Thus, the decoder can simultaneously control the 8 first infrared transmitting tubes 11 respectively.

The second processor 138 may include a second processor 138 input and a plurality of second processor 138 outputs, each second processor 138 output may be coupled to a first end of a second infrared transmitting tube 12, respectively, 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 model 74HC138 decoder having 8 outputs.

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

Thus, the present disclosure can control each of the second infrared emission tubes 12 by providing a plurality of fourth switching control elements 140, and can input different switching signals to each of the second infrared emission tubes 12, respectively, to control the state of each of the second infrared emission tubes 12, respectively. 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 emission tube 12 is turned on and the second infrared emission tube 12 is turned off.

It will be appreciated that: the first controller 145 may be software, and when the software receives a signal that a certain first ir receiving tube 21 is damaged, it controls the driver to open a second ir receiving tube 22 adjacent to the first ir receiving tube 21, so as to replace the damaged first ir receiving tube 21.

In one 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, 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 receiver tube in the infrared receiver 2 can be independently controlled. Therefore, the infrared receiver 2 can make all the infrared receiving pipes work alternately, and when all the infrared receiving pipes work, the sensitivity of the infrared receiver 2 can be increased; when the infrared receiving tubes work alternately, one infrared receiving tube can be used for replacing the other infrared receiving tube to work under the condition that the other infrared receiving tube is damaged. Therefore, when the infrared receiving tube is damaged, the infrared receiving tube 2 does not need to be disassembled for maintenance, and only needs to be opened for replacing the infrared receiving tube. Furthermore, compared to the prior art, the present disclosure can reduce a large amount of maintenance costs, and can prevent the problem of secondary damage to the machine by disassembling 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.

The first infrared receiving tube 21 may also have two ends, namely a first end and a second end. The first end may be a positive end and the second end may be a negative end.

The first end 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.

In one embodiment of the present disclosure, as shown in fig. 1-2, the infrared receiver 2 may further include a second circuit board 29, where the second circuit board 29 may be a printed circuit board, but is not limited thereto, and may be other types of circuit boards, and may be selected according to actual needs. The first infrared receiving tube 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 be other shapes, and may be selected according to actual needs, which will not be described herein.

Further, the second circuit board 29 may have a third region 291 and a fourth region 292. Wherein, a third interval may be provided between two adjacent first infrared receiving tubes 21 in the third area 291, and a fourth interval may be provided between two adjacent first infrared receiving tubes 21 in the fourth area 292. The third interval may be greater than the fourth interval, and at least one second infrared receiving tube 22 may be disposed between two adjacent first infrared receiving tubes 21 in the third region 291. It will be appreciated that the third spacing need be at least greater than the size of one second infrared receiving tube 22.

By this arrangement, the density of the first infrared receiving tubes 21 at the center of the second circuit board 29 can be made smaller than the density of the first infrared receiving tubes 21 at the edges of the circuit board. Therefore, the infrared receiving device can save cost and reduce power consumption under the condition that the infrared receiving precision is met.

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

A first input terminal of the second or gate 233 may be connected to the second terminal of the fifth switch control element 231, and a second input terminal of the second or gate 233 may be connected to an output terminal of the second not gate 232. The second or 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 233 outputs the 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 233 outputs a high level signal; when the first input terminal and the second input terminal both input a low level signal, the second or gate 233 outputs a low level signal.
