Description
Technical field
the utility model relates to a kind of coal preparation plant monitor network, especially by wireless sensor network application a kind of distributed wireless for coal preparation plant and fieldbus monitor network wherein.
Background technology
at present, existing Coal Washing Plant Control network comprises controls network and field apparatus network, when fieldbus breaks down, directly affect its work, poor stability, little, the intelligent degree of amount of information be low, lay that the cable amount is large, the expansion cost is high, dumb, regular maintenance is difficult.
The utility model content
in order to overcome the poor problem of existing Coal Washing Plant Control network stabilization, the utility model provides a kind of distributed wireless for coal preparation plant and fieldbus monitor network, wireless sensor network is applied in coal preparation plant's production, and combine with fieldbus and intelligent control technology, make network under normal circumstances with failure condition under all can steady operation, intelligent degree is high, is convenient to safeguard.
the utility model solves the technical scheme that its technical problem adopts: this coal preparation plant's monitor network comprises PC, observing and controlling substation, wireless monitor substation I, wireless monitor substation II and fieldbus, and wireless monitor substation I, wireless monitor substation II include single-chip microcomputer and wireless module; The serial ports of PC is connected with fieldbus, the observing and controlling substation is connected with fieldbus by its bus interface, wireless monitor substation I is connected with fieldbus by the serial ports of its single-chip microcomputer, PC, observing and controlling substation and wireless monitor substation I are passed through fieldbus transmission information in twos, between wireless monitor substation I and wireless monitor substation II, by the wireless module transmission information, single-chip microcomputer is connected by serial ports and communicates by letter with wireless module.Under normal circumstances, PC is by observing and controlling substation and fieldbus image data, if fieldbus breaks down, by wireless monitor substation II image data, two kinds of communication modes are redundancy each other, guarantees the safe and reliable of transfer of data; Wireless monitor substation II also can be arranged on wiring difficulty or the high place of wiring cost simultaneously, saves cost.
the observing and controlling substation adopts Programmable Logic Controller S7-300PLC, fieldbus adopts RS485, and the single-chip microcomputer model is PIC18F67J11, and wireless module adopts the zigbee transport module DRF1605H of ancient cooking vessel Tyke, Shenzhen Electronics Co., Ltd., be commercially available matured product, directly selection and installation gets final product.
