Technical field
The utility model relates to data control unit, especially a kind of digital data control device.
Background technology
Industry spot has a large amount of digital quantity signal control device., standard simple for the wiring of the control that makes digital quantity signal and transmission generally adopt control module to carry out.But the digital quantity control module cost height of prior art does not have the design protection circuit and removes interfered circuit in circuit, and therefore work is stable inadequately, even can't operate as normal when electromagnetic interference (EMI) is strong, and in addition, speed is also on the low side.
A kind of high speed of market demand, simple in structure, cost is low, the digital data control device of working stability and dependable performance.
The utility model content
The utility model is intended to the above-mentioned deficiency and the market demand at prior art, releases a kind of 16 road digital quantity Data Control boxes, it has at a high speed, simple in structure, cost is low, the characteristics of working stability and dependable performance.
For this reason, the utility model 16 road digital quantity Data Control boxes adopt following technical scheme:
Structure the utility model 16 road digital quantity Data Control boxes comprise buffer circuit, front-end protection filtering circuit and 8 passage output interfaces that two-way is parallel, also comprise microprocessor, communication interface and 485 communication modules; Microprocessor is with the data input buffer circuit, and the output terminal of buffer circuit is connected with front-end protection filtering circuit input end, and the output terminal of front-end protection filtering circuit is connected with 8 passage output interfaces; Microprocessor also is connected with 485 communication modules, and 485 communication modules also are connected with communication interface.
Technique scheme is further set forth:
Described microprocessor is eight bit microprocessors.
Simultaneously, also have the power supply adjusting module, reset/watchdog circuit, and the clock circuit be connected with microprocessor, the power supply adjusting module also links to each other with the external power source interface.
16 road digital quantity Data Control boxes of the present utility model; microprocessor is handled data; calculate; after handling by buffer circuit and front-end protection filtering circuit successively again; control signal is passed to 8 passage output interfaces; by 8 passage output interfaces control signal is transmitted to the multiple controlled device of industry spot, with operation or the work of controlling them.
Also can be sent to host computer (PC computer), by the real-time video data of host computer BGTIO software (with vivid graphics mode) by the data that 485 communication modules are crossed microprocessor processes.By 485 communication modules and communication interface, the digital data that microprocessor processes can be crossed sends the corresponding management module to again, or the data of corresponding management module are sent to microprocessor control.
The utility model is compared with prior art, its beneficial effect is: one, by two 8 parallel passage output interfaces control signal is transmitted to the plurality of devices of industry spot, promptly quite together with 16 digital quantity Data Control module combinations, make more convenient, the simplification of field wiring, and make structure become letter, cost descends.Two, this product is controlled the plurality of devices of industry spot in real time by pull-down pattern, can bear the highest 50V voltage, and the pull-down current maximum can reach 250MA,, volume is small and exquisite, installs simply, and antijamming capability is strong, can be mounted to controlled plant inside.Its three, microprocessor is further handled data, calculates, and by 485 communication modules image data is sent to host computer (PC computer) again, by host computer BGTIO software with the real-time video data of vivid graphics mode.Four, the security and stability that the front-end protection filtering circuit can improve entire circuit is set.Its five, purposes is wide, can be widely used in the digital quantity control of industry spot.Its six, multiple communication baud rate is adjustable, 9600～115200bit/s.
Description of drawings
Fig. 1 is the utility model circuit block diagram.
Embodiment
Below, in conjunction with the accompanying drawings, introduce embodiment of the present utility model.
As shown in Figure 1, the digital control box of the utility model 16 way switch amounts comprises buffer circuit, front-end protection filtering circuit and 8 passage output interfaces that two-way is parallel, also comprises microprocessor, communication interface and 485 communication modules; Microprocessor is with the data input buffer circuit, and the output terminal of buffer circuit is connected with front-end protection filtering circuit input end, and the output terminal of front-end protection filtering circuit is connected with 8 passage output interfaces; Microprocessor also is connected with 485 communication modules, and 485 communication modules also are connected with communication interface.
8 passage output interfaces are input to digital signal the controlled device of industry spot.Microprocessor is selected eight bit microprocessors for use, and its accepts the digital quantity signal from communication interface etc., and can store, and simultaneously, the digital data of putting in order is exported to buffer circuit.Buffer circuit can suppress the influence to circuit of superpotential or excess current.The front-end protection filtering circuit prevents to produce and disturbs in the circuit or the non-switching value target signal filter that produces of surrounding environment.
During use, provide the direct supply of 5V or 12V or 24V to microprocessor, digital quantity signal is input to industry spot by 8 passage output interfaces by the external power source interface.And 485 communication modules are received on 485 networks by communication interface, the utility model just constantly input digit amount signal to the controlled device of industry spot.
The above, it only is preferred embodiment of the present utility model, be not the technician who technical scope of the present utility model is imposed any restrictions the industry, under the inspiration of the technical program, can make some distortion and revise, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model above any modification, equivalent variations and modification that embodiment did.
