[Abstract]:Based on the mechanism that prefabricated beams need maintenance after manufacture, this paper puts forward a method to change the traditional manual maintenance work to intelligent automatic and remote monitoring. A remote control system for spray maintenance of beam yard is developed, which is composed of PLCU 3G network and configuration elements. It reduces the errors and unmonitored phenomena brought by the original manual maintenance, changes the operation parameters of the beam yard on line through the touch screen and PC monitoring center, and realizes the purpose of real-time monitoring the beam yard and recording the query afterwards. It provides a new way to improve the quality of precast beam. The overall design of the application system includes the hardware and software design of PC remote control monitor platform based on GSM network, the data fusion of many beam factories, the operation control of beam factory, the industrial touch screen control system, the multi-channel spray control system, and the field industrial wiring. Wireless data transmission module DTU and other system hardware networking and software design. PC remote monitoring PC is based on the force control Force/Control software development platform, software content includes: user operation authority setting, online display beam field operation status, setting parameters monitoring; The operation parameters of beam yard are saved by database SQL2000, and the spraying parameters of beam yard are monitored in real time at the same time, and the data of the whole maintenance process of each concrete bridge unit are refined to the data record of the whole maintenance process of each concrete bridge unit. It provides an important basis for the analysis of quality accident. In order to meet the mobile characteristics of road construction and facilitate the construction of network at any time when the site changes, the data exchange between the central control computer and the pre-beam factory is through the 3G network of DTU. The industrial touch screen is used to control the beam field. The operation state and parameters of the beam field are changed by RS232 bus and PLC connection. The touch screen is used to control the operation conveniently, and it has several serial data interfaces. At the same time, it is connected with PLC controller. According to the characteristics of large area of beam yard, the optimized wiring. PLC lower position machine mainly realizes the control of dozens of solenoid valves in the field from the aspects of saving wire and improving reliability. It can work reliably in the harsh environment. It can directly drive the work of electromagnetic water valve and water source high power pump, which have large current impact and are prone to circuit faults. Through its RS485 serial interface, it communicates with wireless data transmission module (DTU) and receives the instruction of remote host computer with DTU. Complete the data return operation. The advantage of the system is that the PLC operating program can work independently when the upper computer stops running. In this paper, the layout of the field control cabinet to the multiway water solenoid valve and the reasonable connection mode of the field line are designed. The designed system has been used in the Xingping section of Railway 24 of the West and North Ring Line for one and a half years. Has met the customer's request, has accumulated the successful experience for popularizes the application.
