Description
Technical Field
The utility model relates to a pedestrian passageway floodgate machine infrared inductive switch technical field especially relates to a circuit of multichannel infrared sensor combination output.
Background
The channel gate is a management device with common import and export, is used for managing pedestrian flow and standardizing pedestrian access, and is mainly applied to a subway gate system, a charging ticket checking gate system and the like, because the channel gate is high in intelligence, does not need manual watching inspection, saves human resources and is favored, however, a plurality of infrared sensors are required to be installed on the existing intelligent pedestrian channel gate at the same time, the used infrared sensors are basically in a level signal output mode, the existing infrared sensors in the level signal output mode are all single receiving points and single signal output, each infrared sensor has an independent power line and a signal line, so that the number of the infrared sensors which can only be installed on the pedestrian channel gate is more, the occupied space inside the machine is larger, the number of the electric wires and the cables is also more, and the working efficiency is also lower.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a circuit of multichannel infrared sensor combination output can effectively reduce infrared sensor's connecting wire quantity, practices thrift machine internal wiring space.
The utility model discloses a following technical scheme realizes:
the utility model provides a circuit of multichannel infrared sensor combination output, the circuit of multichannel infrared sensor combination output includes a plurality of independent infrared signal processing system, and is a plurality of independent infrared signal processing system connects in parallel together and uses same power supply, independent infrared signal processing system all is equipped with a signal output port, and is adjacent 2 connect a switch in parallel between the output port, when putting through arbitrary one of them during the switch, adjacent 2 the output port merges to an output signal port, works as all when the switch is put through simultaneously, all the output port merges into an output signal port.
Furthermore, independent infrared signal processing system includes infrared receiving tube, fortune is put, protection circuit, output circuit, and outside infrared light passes through infrared receiving tube, infrared receiving tube converts received signal into level signal, and level signal passes through fortune is put and is carried out amplification processing, finally follows output circuit output level signal, protection circuit is used for protecting independent infrared signal processing system.
The utility model has the advantages that:
the utility model provides a circuit of multichannel infrared sensor combination output is in the same place a plurality of independent infrared inductor, has effectively reduced connecting cable's quantity, and the infrared inductor that the combination was used is more, and the cost is saved more, and in the reduction of connecting cable quantity, also can be very big practice thrift the inside wiring space of machine, wiring time when having saved the installation machine has improved work efficiency.

Fig. 1 is a schematic diagram of a circuit structure of the circuit of the combined output of the multi-channel infrared sensor of the present invention.
Detailed Description
In order to more clearly and completely explain the technical scheme of the present invention, the present invention is further explained with reference to the attached drawings.
Referring to fig. 1, the present invention provides a circuit of multi-channel infrared sensor combination output, the circuit of multi-channel infrared sensor combination output includes a plurality of independent infrared signal processing systems 1, a plurality of independent infrared signal processing systems 1 are connected in parallel and use the same power supply to supply power, independent infrared signal processing systems 1 all have a signal output port, 2 adjacent output ports connect a switch in parallel, when switching on any one of the switches, 2 adjacent output ports merge into an output signal port, when all the switches are switched on simultaneously, all the output ports merge into an output signal port. Independent infrared signal processing system 1 includes infrared receiving tube, fortune, protection circuit 5, output circuit 6, and outside infrared light passes through infrared receiving tube, infrared receiving tube converts received signal into level signal, and level signal passes through fortune is enlargied and is handled, finally follows output circuit 6 output level signal, protection circuit 5 is used for the protection independent infrared signal processing system.
In this embodiment, each independent infrared signal processing system 1 is disposed on the same PCB, infrared light passes through an infrared receiving tube, the infrared receiving tube converts the received signal into a level signal, and the level signal is amplified by the operational amplifier, which is a high level signal or a low level signal output by the output circuit 6. When the switch is in work, any one of the switches is switched on according to needs, the adjacent 2 output ports are combined into one signal output, and a user can receive two level signals simultaneously by connecting any one of the output ports; if all the switches on the PCB are switched on simultaneously, all the output ports on the PCB are combined into 1, and at this time, no matter which path of the independent infrared signal processing system 1 has signal output, a user only needs to connect any one of the output ports; if all the switches on the PCB are turned off, each independent infrared signal processing system 1 can be used as a signal processing system which does not interfere with each other and is used for independently outputting signals, and a user only needs to connect the corresponding output port.
Of course, the present invention can also have other various embodiments, and based on the embodiments, those skilled in the art can obtain other embodiments without any creative work, and all of them belong to the protection scope of the present invention.
