Design And Implementation Of Monitoring For Operation Status Of Controlled Waterway Passing Signal Revealing System

Ships passing through the controlled river section must pass according to the signal revealed by the signal station.The controlled waterway passing signal revealing system reveals automatically reveals the correct traffic signal according to the traffic dynamics of the ship and commands the ship to control the river section in order.The controlled waterway passing signal revealing system running reliably is the key to ensure the safe passage of ships.Due to the poor location environment of the signal station and inconvenient traffic,the traffic signal revealing system is prone to cause system failure owing to voltage fluctuations,electromagnetic interference,high temperature,and humidity.It cannot reveal the signal and endanger the safety of the ship.Therefore,how to further improve the reliability and stability of the system operation,reduce the failure rate,quickly locate the fault and recover the fault,and improve the system maintenance and protection capabilities are the key to the channel management department to ensure traffic safety and traffic efficiency.The paper is based on the existing technology platform,and based on the existing the controlled waterway signal revealing system operating conditions and fault maintenance requirements.It starts from the improvement of system reliability and redesigns the signal revealing controller based on PLC to monitor the operating status of each module.Through the monitoring and analysis of the operating status of each module,the fault point is identified,and a fault maintenance solution is proposed,and an operating status monitoring platform is set up to provide technical support for system maintenance.The following is the main content of the article:(1)Aiming at the current status of digital channel intelligent traffic signal revealing system and operation maintenance management design the system function and framework in detail combined with its business requirements;(2)Aiming at the unstable status of the signal revealer,PLC is used to update the controller to ensure the reliability of the traffic command;for the unstable control of the VHF radio station,a new control circuit is designed to improve the stability of the high-frequency control;(3)For the system lacks the function of monitoring the running status of each module,using multi-threading,visual modeling,human-computer interaction and other technologies,real-time analysis of the status data of the various monitoring points obtained by the lower machine PLC,accurate judgment and try to repair the fault.The main functions of the monitoring platform include fault signal judgment,fault upload,fault analysis,fault self-repair;The system based on PLC updates to design the signal revealing controller and adopts C# to construct the state monitoring system.After application test on site,the effect is good and the design goal is achieved.
