Abstract：  Aiming at the weak linkage control and high energy consumption of early tunnel monitoring systems，a reforming plan of tunnel monitoring system based on traffic flow control was proposed. On the basis of reducing the cost of renovation as much as possible，in this system，due to Kalman filtering technique，the reliable and stable alarm decision was realized； due to linkage control scheme of traffic flow control，coordinate control of the environmental detection system and traffic induction subsystem was realized，at the same time，the tunnel operation efficiency was improved effectively and the reasonable allocation of energy consumption was achieved in tunnel. The results indicate that the ARM embedded control plan of the system has the advantages，with a low cost，high performance characteristics，which is beneficial to the promotion of the system.
