Experiment on Automatic Control Engineering of Water Supply and Drainage System in Station Area of Qinghai-Tibet Railway
According to the special natural environment characteristics of the Qinghai-Tibet Plateau and the requirements of unattended railway management, the intelligent measurement and control system composed of PLC modules, collection modules and digital probes was used in the experiment. This system has the characteristics of all-digital, easy networking, easy expansion, high reliability and so on. The application of three-tier network structure and control logic to the practical engineering of Qinghai-Tibet Railway shows that the system is reliable and feasible.
