The Research Of Highway Tunnel Monitoring System Based On FCS

Highway tunnel is a special part of the highway system. Because the tunnel has relatively small space and complex environment, and the accident happened in a tunnel is difficult to deal with, it's essential to get a monitoring system for a tunnel. The project aims to build a highway tunnel monitoring system based on Fieldbus Control System technology by studying all the aspects of a tunnel. The monitoring system uses the methord of hierarchical control, and regards the regional control layer as the foundation. The main content of this papar is to realize the hardware design of the control module for the regional control layer, and then migrant embedded real-time OS on it.The hardware design of the regional control module includes the schematic and PCB design, which use an ARM microchip as the control core. It includes CAN control module, display module, memory module, power module and reset module. The task of software design is to migrant the embedded real-time OS,μC/OS-Ⅱ, on the hardware unit. It alse include the design of the tasks in a proper way in order to implement the appropriate control procedures. The rest task is to solve the problems that affect the tasks in the real-time OS.
