Brief description of the drawings
Fig. 1 is principle of the invention block diagram.
Embodiment
Below in conjunction with Fig. 1, patent of the present invention is conducted further description.The present invention includes industrial computer, display, converter, Communication Card, PLC1, PLC2, pneumatics unit, cooling driers group, temperature and pressure transmitter, filter pump, ebullator.
Industrial computer is the control core of whole system, is monitoring software operation platform.In industrial computer, configuring USB interface realizes and being connected with converter.Be installed in industrial computer by board, the port one by Communication Card and PLC1, port 2 carry out communication with PLC2 and carry out exchanges data.Industrial computer data acquisition, analyzing stored, computing and control function are connected the demonstration output of industrial computer simultaneously with display, show with display.
Industrial computer carries out communication by converter and pneumatics unit, because the controller of pneumatics unit is only with RS485 communication interface, and adopt MODBUS communications protocol, carry out exchanges data with computing machine and must pass through converter, the control unit interface of each air compressor machine is connected on respectively on the distinct interface of converter, bus between pneumatics unit connects employing separate connection simultaneously, the data acquisition and control that ensures each air compressor machine is independent, and be independent of each other mutually, realize pneumatics unit starting, stop, load, unloading, parameter arranges, monitoring working time, current of electric, the operational factor Real-time Collections such as pressure reduction, record, control.
Industrial computer carries out data acquisition to the motor temperature of pneumatics unit, is connected, completes data acquisition and the transmission at three places before, during and after pneumatics unit spindle motor temperature by multi channel testing registering instrument with converter.
PLC1 carries out Detection & Controling by switching value contact signal to cooling driers group, PLC1 is to the inlet pressure on pipeline, top hole pressure, outlet temperature information simultaneously, the analog signals of pressure, temperature sensor output is transported to the analog module of PLC, after calculation process, send to industrial computer through Communication Card again, shown by display.
PLC2 is to recirculating cooling water system data collection and control, the startup that comprises filter pump stops, the startup of fault detect, running state monitoring, ebullator stops, running status, and cooling tower electric machine starts and stops, motor switches and cooling circulating water system inlet valve gauge tap, valve flow control, cooling water temperature detect, pressure detecting function.By sending to industrial computer through Communication Card after PLC1 calculation process, shown by display again.Communication Card and PLC1, PLC2 pass through bus mode communication, and independent, unaffected separately.
In industrial computer exploitation monitoring software, there are respectively key frame, cooling picture, real time data, historical warning, history curve, system management etc. simultaneously, and there is database storage system function, to real time data process, history data store, statistics, form daily sheet, month form, year form, overcome the loaded down with trivial details and random of manual record data.Operating personnel can carry out telemonitoring and operation to equipment by monitoring software, have improved Centralized Monitoring managerial ability.
