Description
Technical field
The utility model belongs to automatic scanning apparatus field, specifically relates to a kind of input and output control enclosure being applicable to scanner system.
Background technology
The high-tech product that scanner is combined closely as technology such as optics, machinery, electronics, software application is the main computer input apparatus of the third generation after keyboard and mouse.Vitals in scanner is code reader, utilizes code reader to obtain one-dimension code or Quick Response Code.And be connected by input and output control enclosure between scanner with equipment, but existing input and output control enclosure being just provided with various slot, performance is single, cannot programme, and extendability is inadequate, cannot meet the demand of user flexibly.
Utility model content
Technical problem to be solved in the utility model is that the input and output control enclosure performance overcome in prior art between scanner and equipment is single, and the shortcoming that cannot programme, provides a kind of input and output control enclosure.
The utility model solves the technical scheme that its technical matters adopts: input and output control enclosure, comprise PCB, PCB is provided with control chip, opto-coupler chip, RS232 chip, signal input module and signal output module, described control chip is connected with opto-coupler chip, RS232 chip is connected with control chip, and signal input module and signal output module are connected with control chip and opto-coupler chip respectively.
Concrete, described control chip is STC chip.
Further, described STC chip is the chip of STC12C5A32S2 model.
Preferably, signal input module comprises at least two signal input interfaces, and signal output module comprises at least two signal output interfaces.
The beneficial effects of the utility model are: structure is simple, are easy to manufacture, are easy to operation, can need change input/output signal and data layout, carry out data processing, improve ease of use, expand the scope of application according to client.The utility model is applicable to scanner system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, describe the technical solution of the utility model in detail.
As shown in Figure 1, input and output control enclosure of the present utility model comprises PCB, PCB is provided with control chip, opto-coupler chip, RS232 chip, signal input module and signal output module, 1 ~ 8 pin of described control chip is connected with the pin of opto-coupler chip, the pin of RS232 chip is connected with the pin of control chip, and signal input module and signal output module are connected with control chip and opto-coupler chip respectively.Based on realizing effect and cost consideration, described control chip is STC chip, concrete, is the chip of STC12C5A32S2 model.
Signal input module comprises at least two signal input interfaces, and signal output module comprises at least two signal output interfaces.Specific implementation process need arranges input conversion and expansion module and exports conversion and expansion module on these input and output control enclosure, and described input conversion is connected with signal input module and signal output module with expansion module respectively with expansion module and output conversion.Conversion and expansion module comprise conversion and expanded circuit and multiple distinct interface, and multiple distinct interface is by change and the interface in expanded circuit and the external world carries out data transmission.
Scanner is connected with control chip by signal input module, control chip control inputs output signal and communication data.
Its principle is as follows: utilized by control chip and obtain data message, transmitted, then utilize opto-coupler chip control inputs to output signal by RS232 chip.Solve between bar code information and equipment at scanner and do bridge between communication, realize the call between machine and machine, and can manual control.In addition, the number of signal input interface and signal output interface can increase, and control chip can be changed, and the size of PCB can be changed, and expands usable range of the present utility model, improves ease of use.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
