Abstract
The utility model discloses a Profibus-DP technology-based refrigerator unit central monitoring system, and comprises a superior computer and a plurality of refrigerator-unit control systems; each refrigerator-unit control system is connected with an on-site but through a CP communication module; the on-site bus is connected with the on-site bus communication CP5611 of the superior computer. The central monitoring system can better resolve the problem of the address inflict when multiple refrigerator-unit control systems are accessed to the screenwork, thereby realizing the central monitoring on multiple refrigerator-unit control systems on site, thus greatly reducing the labor working intensity and the labor-force cost, and also can realize the remote data transmission.
Description
Technical field
The utility model relates to a kind of monitoring system of factory, particularly a kind of monitoring system that can realize CSRC to many freezing units.
Background technology
In existing monitoring system, every C7 633P and integrated monitoring system on the spot of 0P7 monitoring face that the refrigerator set control system is Siemens PLC C, because this system need be provided with an independent control system at every freezing unit, thereby patrol and examine and the modification of parameter of this system's instrument just need special frequent the patrolling and examining and revise to the scene of instrument worker, when carrying out work night, job requirement to the workman is bigger, this with regard to invisible increase labour intensity and cost of labor, make production cost of products increase greatly, reduced the competitiveness of product in market.If monitor by central monitoring system, because in the integrated system of C7 633P and 0P7, C7 633P and 0P7 address number are fixed, though C7 633P can be provided with by STEP 7, must revise address among the 0P7 simultaneously.But the modification of 0P7 software is in the maintaining secrecy of technology, can not makes amendment original document, many C7 633P-0P7 systems connections then, it is urgent problem that different addresses is set.
The utility model content
The utility model is at the problems referred to above, and proposed a kind of central monitoring system of the address conflict problem can solve many refrigerator set control systems networkings the time.
In order to reach described purpose, the monitoring system that the utility model provides comprises:
Host computer and with many refrigerator set control systems; Its described every refrigerator set control system connects fieldbus by the CP communication module, and this fieldbus is connected with fieldbus card CP5611 in the host computer.
Above-mentioned fieldbus is the Profibus-DP bus.
Address conflict problem when the utility model can be good at solving many refrigerator set control system networkings, thereby realize many refrigerator set control systems at scene are carried out CSRC, greatly reduce labor strength and cost of labor, can also realize remote transfer of data simultaneously; The utility model is simple in structure, realizes easily.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the schematic diagram of existing monitoring system.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect
Be easy to understand,, further set forth the utility model below in conjunction with concrete diagram.
According to Fig. 1 as can be known, original system finds that by Siemens STEP7 systems soft ware the freezing unit C7 633P address of three platform independent is provided with has only 2, so can only be connected in 2 MPI networks, can't form communication network in a cover MPI communication system.But every C7 633P supports the CP communication module, and the CP communication module has the DP mouth, realizes like this three DP port address are reset, and forms the Profibus-DP bus system, realizes CSRC (as shown in Figure 2).Be implemented as follows:
What three refrigerator set control systems in this monitoring system adopted is C7 633P and the integrated monitoring system on the spot of 0P7 monitoring face of Siemens PLC C, because this system need insert the Profibus-DP network, and its C7 633P does not have the DP interface, so configuration CP communication module on every C7 633P, this CP communication module is integrated with the DP interface, promptly by this interface C7 633P is connected on the Profibus-DP bus, the Profibus-DP bus is also connected to the CP5611 address card in the host computer.Finish above-mentioned connection, in the Profibus-DP network, be the DP address by the address that C7 633P and 0P7 are set among the STEP 7, first DP address is 2, location, second tableland is 3, the 3rd is 4, address conflict problem in the time of can solving the networking of many refrigerator set control systems will can be owing to confusion takes place address conflict when itself and host computer carry out communication.
More than be one of embodiment of the present utility model,, do not spend performing creative labour, on the basis of the foregoing description, can do multiple variation, can realize the purpose of this utility model equally for those skilled in the art.But this variation obviously should be in the protection domain of claims of the present utility model.
Claims (3)
1, based on the freezing unit central monitoring system of Profibus-DP technology, this system comprises host computer and a plurality of refrigerator set control system; It is characterized in that described every refrigerator set control system connects fieldbus, the field bus communication card connection in this fieldbus and the host computer by the CP communication module.
2, the freezing unit central monitoring system based on the Profibus-DP technology according to claim 1 is characterized in that described fieldbus is the Profibus-DP bus.
