Description
Technical field
The utility model relates to a kind of electrical system, especially a kind of PLC analog control system.
Background technology
At present, when the PLC development system, often can only write all programs earlier, be applied in the Industry Control and go, such performance history exists very big defective, because the debugging work of PLC program can only just can be carried out later in whole hardware system installation, could carry out perfectly to system, so not only can prolong the duration, and even can be because of some details carelessness, and cause whole procedure to make amendment, increased the weight of research staff's burden; In addition, this makes some company all bear very big risk when developing new product, because research and develop model machine hastily, just can cause tremendous loss in case get nowhere, and performance history can not become quite complicated because there being reference in kind yet.And aspect teaching, the student does experiment, and during teachers ' scientific research, more impossible have enough resources to provide ready-made equipment for them, and this has caused very big restriction for carrying out of teaching and research work.
Summary of the invention
The purpose of this utility model is a kind of PLC analog control system that can simulate the system that is developed that provides for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the PLC analog control system that the utility model is designed, it mainly comprises PLC, also comprise the host computer and the sophisticated interface module that are used for analog component, communicate to connect between host computer and the sophisticated interface module, by communication that the components and parts of simulation are corresponding one by one with the address in the sophisticated interface module, PLC is connected with the host computer signal by sophisticated interface module, and the operational order of PLC is controlled the components and parts of simulating on the host computer as control signal.Described sophisticated interface module can be PLC, single-chip microcomputer or other smart machine by programming, can carry out two-way data transmission for PLC and sophisticated interface module, can be provided with two-way I/O port on the described sophisticated interface module.Connect for convenience, increase the versatility of equipment, can reach good effect again, described host computer is that RS232 is connected with sophisticated interface module, and described host computer is preferably PC or HMI.
The resultant PLC analog control system of the utility model utilizes the parts of the machinery of computer technology analog physical, sets up the control program empirical model according to commercial unit.So just, reach the limit research and development, the limit test, improve on the limit, until reaching designing requirement.The program of developing like this can be used fully in the actual industrial control and go, and according to the control program empirical model design model machine of setting up, walks a lot of detours less, shortens the research and development time greatly, saves R﹠D costs greatly.The present invention is except giving large enterprise, and scientific research office also can give the university teacher as outside the PLC analog control system, and the post-doctor is as outside the scientific research, and the graduate does graduation project and uses.

Fig. 2 is the structural representation of the utility model embodiment 1;
Fig. 3 is the picture of simulation water tower experiment.
Among the figure: PLC1, host computer 2, sophisticated interface module 3, two-way I/O port 4, water tower 5, motor 6, last water level signal switch 7, following water level signal switch 8, water tank 9.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, the described PLC analog control system of present embodiment, it mainly comprises PLC1, also comprise the host computer 2 and the sophisticated interface module 3 that are used for analog component, communicate to connect between host computer 2 and the sophisticated interface module 3, by communication that the components and parts of simulation are corresponding one by one with the address in the sophisticated interface module 3, PLC1 is connected with host computer 2 signals by sophisticated interface module 3, and the operational order of PLC1 is controlled the components and parts of simulation on the host computer 2 as control signal.Can carry out two-way data transmission for PLC1 and sophisticated interface module 3, described sophisticated interface module 3 is provided with two-way I/O port 4.Connect for convenience, increase the versatility of equipment, can reach good effect again, host computer 2 and sophisticated interface module 3 are for RS232 is connected, and host computer 2 is a PC, and sophisticated interface module 3 is a small-sized PLC1, and sophisticated interface module 3 also can be single-chip microcomputer.
The control method of above-mentioned PLC analog control system, employing analog component and utilize this element to form electrical system on host computer 2, and it is the components and parts of simulation are corresponding one by one with the address in the sophisticated interface module 3, PLC1 operates the components and parts on the host computer 2 by the corresponding address in the sophisticated interface module 3, finishes the simulation control of electrical system.Analog component and to utilize this element to form electrical system be by being installed in the configuration software analogsimulation components and parts on the PC and utilizing this element to form electrical system on host computer 2.Analog component is to carry out function modelling by the actual change rule rate to element on host computer 2, and function is consistent therewith to make the Changing Pattern of element.
In teaching in the experiment of a simulation water tower 5 being used, on the host computer picture as shown in Figure 3, the I/O port is defined as follows on the sophisticated interface module 3:
| Terminal number | Definition | Action | |
| | Water motor | 6 starts on the |
After the startup water is carried to |
| Y00 | The last water |
It is then closed that water level is higher than switch | |
| Y01 | The following water |
Water level is lower than switch and then disconnects |
The input/output terminal of PLC1 just can be operated the element in the host computer 2 with after I/O port on the sophisticated interface module 3 links to each other.Such as, the digital quantity output point Q0.1 of PLC1 is connected with X00 on the sophisticated interface module 3, PLC1 puts Q0.1 at 1 o'clock, and the water motor 6 on the host computer 2 starts and will start, and water is promptly carried to water tower 5 from water tank 9.Water tower 5 is to carry out function modelling by the actual change rule rate to water tower 5 on host computer 2, and function is consistent therewith to make the Changing Pattern of water tower 5, the function that water tower 5 adopted can pass through that cutting of the water tower 5 that adopted amassed, the power of motor 6, the pressure of water tank 9 etc. are comprehensively calculated, when the water that enter water tower 5 just can be gone up the water level switch action according to this function during to a high position.Because the model of water tower 5, the model of motor 6 is a lot, and computing method are prior aries, and those of ordinary skills calculate according to actual conditions, so do not add detailed description at this.
