Description
Technical field
The invention belongs to industrial automation control system technical field, is related to a kind of various PLC functions controls run based on PC
Fabrication and its using method.
Background technology
PLC is usually that a kind of PLC of model only possesses certain specific function and specific using method.If you will use
Other functions, such as you can only change PLC during the function of Rhizoma Sparganii Q series of PLC or other producers PLC.It is right so to will result in
The high problem of system conversion time length and input cost, particularly in school, this application places are more projected.Ask for this
Topic, is connected with electric control panel by serial communication with VB language design computer upper computer softwares, obtains the defeated of PLC control system
Enter signal.Then pass through host computer（PLCSIM communication softwares）With PLC producers engineering software artificial debugging environmental interaction, PLC journeys
Sequence performs computing and produces corresponding result, is then connected with electric control panel by serial communication, PLC peripheries output signal defeated
Go out to corresponding port, so as to control corresponding actuator.Such system can complete the function of a PLC substantially.This
If sample I only need to when will change PLC system change software design patterns, it is not necessary to change hardware device, it is also possible to reduce
The use cost of PLC.
Mainstays of the PLC as industry automatic control, using widely in Industry Control.One important technology
Popularization, be unable to do without input and configuration that each compound proofreads the subject.But due to PLC technology mainly run into during popularization with
The problem of lower several respects：1st, PLC prices itself are high.2nd, PLC experience systems typically by Jiao Yi device fabrications company being relatively fixed
Task as a kind of carrier, carry out manufacture sale.Even if a very simple training platform, price all can be very high.Here
The price of PLC is even more and is higher by general selling price.3rd, under Multiple Type PLC use environments, if will be equipped with corresponding
The PLC of model, not only input cost is high, and takes real training place greatly, causes the problem that later maintenance cost is high.4th, PLC factories
The computer debugging system of family is a kind of entirely virtual analogue system, it is impossible to which directly and quickly connecting hardware carries out debugging fortune
OK, if hardware debugging will be carried out, still to be debugged by PLC entities.So complete virtual artificial debugging can be caused
PLC some unstable signals, uncertain signal and live interference signal cannot carry out artificial debugging.Impact system it is complete
Debugging, it is impossible to allow emulation and be formed in situ seamless docking.Good professional quality cannot be formed using PLC processes so.5、
When PLC some signals are debugged and are monitored, the display lamp or on-line monitoring program of overview PLC, if but adjust
Examination station（Engineer station）Can all cause to monitoring input/output signal in the case of very long with the distant or PLC program in PLC scenes
Aspect and observation internal PLC signal be not directly perceived.Cause the debugging system time long, the troublesome phenomenon of program maintenance.
The content of the invention
In order to overcome the disadvantages mentioned above of prior art, the present invention to provide a kind of various PLC function controls run based on PC
Card and its using method, it can replace the function of PLC hardware, by computer upper computer software and electric control panel, pass through
Interact with the simulated environment of PLC producers, form a system, such system is filled with respect to PLC producers PLC entities or PLC real trainings
Low cost is put, the use of main compatibility different model PLC, when PLC type is changed, it is only necessary to which upper computer software sets PLC machine
Type, it is easy to operate.Its hardware device need not be changed when PLC system is changed.Simultaneously in debugging routine or system,
The debugging that the various signals of PLC accelerate program is observed by the display lamp or FPDP visual pattern of host computer, journey is reduced
The maintenance time of sequence, so as to strive for more real training times, PLC binding posts typically adopt screw stationary structure, such as fruit
Want Jing often to carry out system line connection in instruction study, due to misoperation or operation excessively frequently, the terminal of PLC can be caused
Fatal destruction, and this device compresses binding post using the screw that screwless connection terminal replaces PLC traditional, it is relative to improve
The agility of PLC system connection, and the abrasion of PLC binding posts is reduced, to sum up contrasted, substantially reduced PLC system reality
The cost of instruction.
The technical solution adopted for the present invention to solve the technical problems is：A kind of various PLC functions controls run based on PC
Outside single-chip microcomputer, PLC system and PCL in fabrication, including host computer, PLC computer debugging systems, electric input and output panel
Hardware system is enclosed, is installed on VB exploitation software, with PLC computers debugging system and electric input and output panel in host computer
Single-chip microcomputer interaction data, includes input/output switching signal and high-speed pulse signal in interactive packet, basic to realize
Digital output modul or stepping servo control, complete the debugging and control of PLC program.
A kind of using method of the various PLC function controls cards run based on PC, its step is：Host computer is developed using VB
Communication software is interacted with the single-chip microcomputer in PLC computers debugging system and electric input and output panel simultaneously, completes indirectly PLC
The debugging and control of program, it is main to adopt PLC Serial Communications and microcomputer series interface communication technology to complete leading between them
News interaction, electric input and output panel mainly by single-chip microcomputer be control core, control hardware system input and output carry out letter
Number collection and
Object control.
The electrical control input and output panel consists predominantly of power module：24V、5V；Communication module：Serial ports leads to
Letter, usb communication；Single-chip Controlling input/output module：Input is made up of photoelectric coupled circuit, and output is made up of relay circuit.
