Summary of the invention
Technical matters to be solved by this invention is the shortcoming that the IO interface overcoming existing code reader only has, provides a kind of code reader expansion input-output unit that effectively can increase IO interface number.
The technical solution adopted for the present invention to solve the technical problems is: code reader expansion input-output unit, comprise PCB, described PCB is provided with the code reader connectivity port for being connected with code reader, PCB is also provided with control chip, opto-coupler chip, RS232 chip, signal input module and signal output module, control chip respectively with code reader connectivity port, opto-coupler chip, RS232 chip, signal input module and signal output module are connected, signal input module and signal output module are also connected with opto-coupler chip respectively, also comprise conversion expansion module, described conversion expansion module comprises input conversion expansion module and exports conversion expansion module, conversion expansion module comprises conversion expanded circuit and several distinct interface, several distinct interface carries out data transmission by conversion expanded circuit with extraneous interface, described input conversion expansion module is connected with signal output module with signal input module respectively with output conversion expansion module.
Concrete, described control chip is STC chip.
Preferably, described STC chip is the chip of STC12C5A32S2 model.
Further, the housing being arranged on PCB, each chip and module-external is also comprised.
Further, PCB is also provided with relay, described relay is connected with control chip.
The invention has the beneficial effects as follows: structure is simple, be easy to operation, this expanding unit complete function, outward appearance is clean and tidy, and can need to change input and output quantity according to client, the IO interface number in effective spread signal load module and signal output module, expands the scope of application; In addition, control chip etc. can also be utilized to control signal input module and signal output module, by program by information transmission on multichannel external equipment.The present invention is applicable to code reader.
Accompanying drawing explanation
