Abstract
The invention relates to a communication protocol of an upper computer centralized monitoring system for drainage workshop circulating water. The communication protocol comprises a PLC (programmable logic controller) and touch screen communication protocol 1, a PLC and upper computer communication protocol 2, a PLC and wireless station communication protocol 3, a lifting pump room and wireless station communication protocol 4 and a secondary circulating water and 3# side-filtering chemical-feeding system communication protocol 5. The communication protocol has the advantage that upper computer centralized monitoring for the drainage workshop circulating water is achieved by minimum modification and construction costs under an existing space wiring condition.
Description
technical field
The present invention relates to the communications protocol of the host computer centralized monitoring system of recirculated water between a kind of drainage car.
Background technology
Between the drainage car of Kelamayi general petrochemicals factory, the centralized monitoring system transformation of recirculated water carries out on the basis both had living space, its former design adopts communication cable to connect, transmission data mode, its shortcoming is that cable wiring manufacture cost is higher, needs to carry out larger transformation to All other routes.
summary of the invention.
The object of the present invention is to provide the communications protocol of the host computer centralized monitoring system of recirculated water between a kind of drainage car, be intended to reduce construction wiring cost, under existing space wiring situation, realize the communications protocol of the host computer centralized monitor of recirculated water between drainage car with minimum change and construction cost.For achieving the above object, the technical solution used in the present invention is
:the present invention relates to the communications protocol of the communications protocol of the host computer centralized monitoring system of recirculated water between a kind of drainage car
,filter medicine system communications protocol 5 by communications protocol between PLC and touch-screen 1, PLC and upper machine communication agreement 2, PLC and radio station's communications protocol 3, lift pump room and radio station's communications protocol 4, two-cycle and 3# side to form, it is characterized in that the two-cycle of the communications protocol of the communications protocol of the host computer centralized monitoring system of recirculated water between described a kind of drainage car and 3# is other filters medicine system 5 and adopt RS-422 communication, two-cycle side interface is set to the grand communication of agreement, and 3# other filter medicine system side is MODBUS (RTU) agreement.Between described PLC and touch-screen, communications protocol 1 adopts RS-232 communication, and agreement is NT LINK (OMRON touch-screen high-speed communication protocol).Described PLC adopts RS-232 to be connected with upper machine communication agreement 2, and agreement is HOST LINK (upper machine communication agreement).The interface of described, lift pump room and radio station's communications protocol 4 is set to HOST LINK.
