Precast Beam Field Sprinkler Maintenance Of Remote Monitoring System Design

In this paper, from the mechanism of the preform manufacture after the completion of the beam need maintenance starting, puts forward the artificial maintenance work instead of traditional method with intelligent automatic and remote monitoring, introduces a kind of prefabricated, based on PLC 、configuration software and GRRS network beam field spraying curing remote control system. Put an end to the original manual maintenance caused by mistakes and can not monitor phenomenon occurs, touch screen and PC monitoring center through the change online beam field operation parameters, realizes the real-time monitoring of beam field and afterwards record query function, provides a new way to improve the quality of precast beam.The overall design of the application system including software and hardware monitoring platform of PC remote control computer GSM network design, multiple beam factory based data fusion, operation control operation of industrial touch screen control system, multiple spray control PLC, industrial field wiring beam factory, the wireless data transmission module DTU system hardware and software design of network.PC remote monitoring PC is based on force control Force/Control software as a development platform, the software includes: the user permissions settings, online display running status of beam field, setting parameter monitoring; use the SQL2000 database to save the beam field operation parameters, at the same time online on the Liang Changjin line real-time monitoring, spraying parameters on the beam field generation the report, to refine the whole curing process data recording every concrete bridge unit, provide an important basis for quality accident analysis. In order to meet the mobile characteristics of road construction, easy in the site changes at any time networking, central control computer and the prefabricated beam plant data exchange through DTU of 3G network.Beam field control operation selected industrial touch screen connected to complete the change of beam field running state and parameters through RS232 bus and PLC, using the touch screen control easy to operate, it has multiple serial data interface, which is connected with the PLC controller in the completion of the station digital graphic monitoring and.According to the beam field of large area characteristics, optimized wiring from saving wires and reliability.PLC lower position machine is mainly to achieve control of the scene dozens of electromagnetic valve, can work reliably in the field under the bad environment, and candirectly drive the electromagnetic water valve and a water source high power pump current impact of large work, communication module of DTU communication through the RS485 serial interface and the wireless data, accept the remote computer program with DTU the control action is implemented. The utility model also has the advantages of PC system when stopped running, PLC can work independently.The design of the scene from the control cabinet to the multi-channel water electromagnetic valve arrangement and reasonable spot line connection methods, spent a year and a half to use design system has iron in Xi Xian Nol 24 Bureau of the Xingping section,meet customer requirements, has accumulated successful experience for application.
