Abstract

The utility model discloses an air compressor plant long-distance networking control system which comprises an air compressor controller, a client, a first PLC (Programmable Logic Controller) master station, a second PLC master station and an Ethernet switch, wherein the air compressor controller is connected by a communication network cable and is connected with the first PLC master station by a bus; the first PLC master station, the second PLC master station and the client are accessed to the Ethernet switch; the Ethernet switch is accessed to a steel works production network to realize the connection with the whole steel works production network; the first PLC master station reads the operation state of the air compressor and writes the state into the second PLC master station; after the second PLC master station analyzes the state, a control instruction is sent to the steel works production network by the Ethernet switch to control the work of the air compressor; the client reads the operation state parameter of the second PLC master station, and displays the operation state parameter on a monitoring interface; when a fault occurs to a monitoring point, a red alarm signal is displayed or the equipment hops and stops, and long-distance concentrated automatic control is thus realized.

Description

A kind of air compressor plant long-distance on-line control system

Technical field

The utility model belongs to air compressor plant control system, is specifically related to a kind of air compressor plant long-distance on-line control system.

Background technique

Often there is multiple air compressors in steel works air compressor plant at present, between each air compressor, be single devices, mutually, it doesn't matter, do not possess multiple linkage control function, when air compressor catastrophic failure, operator can not carry out emergency reaction in time, very easily causes supply gas pressure unstable, affects normal production run; Do not possess remote control function, operator needs local operation, and oneself is placed in to high-decibel noise source for a long time, and the harm operator person is healthy.

Model utility content

The utility model aims to provide a kind of system that can realize multiple air compressors networking control, and this system can centralized automatic control, can know in time guilty culprit place when realizing operator's remote operation and breaking down.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of air compressor plant long-distance on-line control system, comprise air compressor controller, client computer, a PLC main website, the 2nd PLC main website and Ethernet switch, between air compressor controller, connect by communication netting twine, and access a PLC main website by bus; The one PLC main website, the 2nd PLC main website and client computer were all connected in access network based on ethernet switchboard and are realized and networking; Ethernet switch access steel works is produced in net and is realized with whole steel works and produce being connected of net.

The utility model, by multiple air compressors is carried out to long-distance on-line control, can allow operator carry out remote job, prevents from being placed in for a long time the health of human body destruction that high-decibel noise source causes operator; There is monitored picture simultaneously, can show in time fault point, make operator open in time emergency preplan.

Brief description of the drawings

Fig. 1 is the theory diagram of air compressor plant described in the utility model long-distance on-line control system.

Embodiment

As Fig. 1, a kind of air compressor plant long-distance on-line control system, comprises multiple air compressors controller, a PLC main website, the 2nd PLC main website, client computer and Ethernet switch.

In present embodiment taking 7 air compressor controllers as example, comprise 1# air compressor controller, 2# air compressor controller, 3# air compressor controller, 4# air compressor controller, 5# air compressor controller, 6# air compressor controller and 7# air compressor controller, wherein between 1# air compressor controller and 2# air compressor controller, be connected by communication netting twine, between 2# air compressor controller and 3# air compressor controller, be connected by communication netting twine, between 3# air compressor controller and 4# air compressor controller, be connected by communication netting twine, between 4# air compressor controller and 5# air compressor controller, be connected by communication netting twine, between 5# air compressor controller and 6# air compressor controller, be connected by communication netting twine, between 6# air compressor controller and 7# air compressor controller, be connected by communication netting twine, 7# air compressor controller is connected with the 2nd PLC main website by bus.

Thereby the 2nd PLC main website, a PLC main website, client computer are all arranged in Ethernet realization networking by realization in access network based on ethernet switchboard, Ethernet switch realizes in netting by the production of access steel works and whole steel works is produced being connected of net.

Between the one PLC main website and air compressor controller, carry out communication by MOD-BUS agreement, the one PLC main website processes the Communication with air compressor controller, a PLC main website and the 2nd PLC main website carry out the mutual of read and write by Ethernet switch simultaneously, the one PLC main website by and air compressor controller between carry out communication and read in compressor operation state, and this state is write to the 2nd PLC main website, the 2nd PLC main website receives this communication information, produces online sending controling instruction the work of air compressor is controlled after analysis by Ethernet switch to steel works.

Client access the 2nd PLC main website also reads in the compressor operation status parameter in the 2nd PLC main website, as the startup of air compressor plant, interlocking, lubricant oil situation, exhaust pressure, temperature, cooling water, filter etc., and these states are shown on the monitoring interface of client computer, in the time breaking down in monitoring point, design shows or equipment stop jumping with red alarm signal, automatically controls thereby realize remote centralized.

The disclosed air compressor plant of the utility model long-distance on-line control system, can realize the remote operation of air compressor plant and the timely demonstration of fault.

Claims

1. an air compressor plant long-distance on-line control system, comprise air compressor controller and client computer, it is characterized in that: also comprise a PLC main website, the 2nd PLC main website and Ethernet switch, between air compressor controller, connect by communication netting twine, and access a PLC main website by bus; The one PLC main website, the 2nd PLC main website and client computer were all connected in access network based on ethernet switchboard and are realized and networking; Ethernet switch access steel works is produced in net and is realized with whole steel works and produce being connected of net.
