[Abstract]:In order to improve the automation and information level of tunnel construction ventilation system, a framework of tunnel construction ventilation monitoring system based on industrial Ethernet network is proposed. The system is composed of upper industrial control computer, lower 1200 series PLC and related modules and sensors. In the industrial control computer, Win CC software is used to compile the monitoring program to realize the real-time monitoring of the tunnel construction environment and working parameters, and the neural network algorithm is used to study the field data. The control rule of output frequency of frequency converter is obtained. 1200PLC reads sensor data through 485 cable, and the industrial Ethernet network is made up of optical fiber and wireless local area network, which can realize the sharing of system environment parameters and working parameters. The system was debugged and tested in the ventilation project department of Tianmushan Tunnel. The results show that the system can use 485 cable and Modbus protocol to read the data of multiple sensors successfully in the palm construction environment. The wireless WIFI technology can be used to realize the stability of the information between the two ends of the lining platform. The neural network model can be used to realize the nonlinear mapping between the environmental parameters of the tunnel and the frequency of the fan.
