Background technology
Present industrial control system generally adopts host computer, slave computer to communicate with one another and jointly controls the form of commercial unit.Host computer adopts computing machine usually, and slave computer adopts industrial control unit (ICU) usually, for example programmable logic controller (PLC) PLC (Programmable Logical Controller).As shown in Figure 1, Fig. 1 is the basic structure synoptic diagram according to the industrial control system of prior art.Host computer and slave computer carry out communication through bus network in Fig. 1.
For example in the production run of concrete mixing plant; Generally be as slave computer and as the control core with PLC; Computing machine is sent to slave computer production as the operational order that host computer sends through bus or internetwork connection mode; And production status fed back to host computer in real time, thereby realize the production run of mixing plant.
If host computer breaks down, then slave computer can't obtain operational order, thereby influences production run.For the industrial control system of other kinds, also there is similar phenomenon.Therefore existing industrial control system reliability is not high.
The reliability of industrial control system is not high in the prior art, for this problem, does not propose effective solution at present as yet.
The utility model content
The fundamental purpose of the utility model provides a kind of industrial control system, to solve the not high problem of reliability of industrial control system in the prior art.
The industrial control system of the utility model comprises interconnected main frame and industrial control unit (ICU), and wherein main frame is used for providing the industrial control unit (ICU) operation required production data to industrial control unit (ICU), and system also comprises the data processing equipment that is connected with industrial control unit (ICU); Data processing equipment is used to preserve the production data of reception, and is used for when satisfying, production data being offered industrial control unit (ICU) pre-conditioned.
Technical scheme according to the utility model; Through data processing equipment is connected with industrial control unit (ICU); When satisfying, production data is offered industrial control unit (ICU) pre-conditioned, like this when host computer crashes suddenly or be out of control; Can replace host computer to continue production run by data processing equipment, thereby help to improve the reliability of industrial control system.
Description of drawings
Figure of description is used to provide the further understanding to the utility model, constitutes the application's a part, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is the basic structure synoptic diagram according to the industrial control system of prior art;
Fig. 2 is the synoptic diagram according to the basic structure of the industrial control system of the utility model embodiment.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the utility model.
Fig. 2 is the synoptic diagram according to the basic structure of the industrial control system of the utility model embodiment; As shown in Figure 2, this system mainly comprises main frame 21, industrial control unit (ICU) 22 and data processing equipment 23, and wherein industrial control unit (ICU) 22 can be PLC; Data processing equipment 23 can have touch-screen; Can realize man-machine interaction through touch-screen, for example import production data through touch-screen, receive and preserve by data processing equipment 23 by personnel.Data processing equipment 23 can also have the port of Data Receiving so that receive production data and preservation through wired or wireless mode.Main frame is used for providing the industrial control unit (ICU) operation required production data to said industrial control unit (ICU) as host computer.Main frame and as connecting through industry ethernet between the industrial control unit (ICU) of slave computer.
In the present embodiment with data processing equipment have touch-screen (hereinafter abbreviating this data processing equipment as " touch-screen "), industrial control unit (ICU) is that PLC is that example describes.
Present embodiment is through touch-screen is connected with PLC, and after main frame sent to PLC with production data, backup read and saved as to touch-screen can with this production data from PLC; Also can be in touch-screen direct target setting value, carry out with the PLC system that data transmit and exchange, for example mixing time, discharging time etc. write the PLC system with the production data of outside input; Can also PLC internal system data be read in touch-screen, realize the real-time demonstration of analog quantity, the setting of desired value and generation warning message etc.Can be connected through RS485 bus or RS232 bus between touch-screen and the main frame.
When proper communication, host computer and PLC carry out communication through the bus network connected mode, and at this moment, PLC only accepts the host computer order.Send a command to PLC by host computer, and sensor, Displaying Meter etc. will be sent into PLC by coherent signal handle, realize the mutual conversion of analog quantity and data volume.Simultaneously, also can be in touch-screen direct target setting value, carry out communication through splicing ear and PLC, convert analog quantity into data volume, control the operation of production system.As shown in Figure 2, RXD, TXD are the splicing ear of touch-screen and PLC.
Under pre-conditioned satisfied situation; Touch-screen is sent to PLC with manufacturing parameter, and for example this condition can be that touch-screen is received the peripheral operation signal, when host computer crashes suddenly; The Systems Operator manually switches to slave mode with touch-screen; This blocked operation promptly produces above-mentioned peripheral operation signal, and this moment, touch-screen was sent to PLC with production data or the Systems Operator of the backup service data through the touch-screen input, thereby realized that touch-screen replaces host computer to continue to produce.In addition, touch-screen can regularly or irregularly send Query Information to main frame, and main frame responds after receiving this Query Information, promptly sends response message to touch-screen.Above-mentioned so pre-conditioned also can be that touch-screen is not received the response message that main frame sends.
Show set relevant parameters value respectively in the viewing area of touch-screen, in digital memory, occupy corresponding storage area, simultaneously; Be mapped through the address of digital memory table and the position of PLC digital storage area; PLC is according to the data read command of touch-screen, and is in service in system, will send into PLC by coherent signal by sensor, Displaying Meter etc. and handle; Thereby realize the temporary transient function that replaces host computer, production run can not stopped suddenly.
Technical scheme according to the utility model embodiment; Data processing equipment is connected with industrial control unit (ICU); In this data processing equipment, preserve production data, like this, when host computer crashes suddenly or is out of control; Can replace host computer production by this data processing equipment, help to guarantee the continuity of production run.The technical scheme of present embodiment is applicable to abominable industrial environment, and enantiotropy is good, and is simple to operate, and antijamming capability is strong, helps to improve the reliability of industrial control system.
