| This article base on the "the Zhang Jiajie YuYuan tunnel safety monitoring system" project and the relevant national standards, design the YuYuan tunnel monitoring system overally, and study the related key technologies for the tunnel operating energy saving.Firstly, according to the actual situation of the YuYuan tunnel, combined with relevant national standards, tunnel monitoring system is divided into the central monitoring subsystem, the ventilation control subsystem, the illumination control subsystem, the traffic guidance control subsystems, the video monitoring subsystem and the fire alarm subsystem. And the article analyze the needs of the functional requirements of the monitoring subsystems and other monitoring functions. Then in this article, the overview of the overall design of the tunnel monitoring system were described through monitoring system monitoring rating classification, field device configuration, monitoring network design, system control processes. Finally, it studies the tunnel lighting and ventilation energy-saving control technology, and described the process of establishing fuzzy control system based on fuzzy control technology. It verify the effectiveness of the fuzzy control technology through the simulation of the control process and the output of the fuzzy control. And it realizes the fuzzy control algorithm in PLC and designs the lighting HMI and the ventilating HMI by the WinCC software. |
