Redundancy control system and method for railway robot to automatically pass through fire exit door

Abstract

The invention discloses a redundancy control system and method for a railway robot to automatically pass through a fire exit door. The robot can be accessed into tunnel optical fiber Ethernet through tunnel WIFI (Wireless Fidelity) coverage, so as to control the state of the fire exit door; when the robot passes through the fire exit door, the fire exit door is controlled to be opened and closed; if a fire disaster or an abnormal condition occurs in a tunnel and an trunk optical fiber or WIFI coverage equipment is damaged, the inspection robot can control the fire exit door to be opened and closed through a second data link Zigbee or other near field communication manners when the inspection robot gets close to the fire exit door of the tunnel, so that a condition that the robot cannot control the fire exit door is avoided; if a power supply system of the field fire exit door is invalid, an electric mortise lock of the fire exit door is invalid, and the robot can still escape from a fireproof zone through a manner of jacking a front-end bumper.

Description

technical field [0001] The invention relates to a redundant control system and method for an orbital robot to automatically pass through a fire door. Background technique [0002] Urban cable tunnels are important public infrastructures. Generally, 110KV or 500KV high-voltage cables are installed inside. These are the main arteries of urban power supply. Once the cables explode and catch fire, it will cause more serious fires and power outages, with serious consequences. [0003] At present, the interior of the cable tunnel is composed of several fire-fighting partitions separated by fire doors. Each fire-fighting partition is equipped with fire-fighting water supply and fire-fighting supporting facilities. At present, some cable tunnels have installed intelligent inspection equipment to replace part of the work of personnel. The current inspection robots usually use direct mechanical top opening or single data link control when passing through fire doors, but both methods ...

Problems solved by technology

The current inspection robots usually use direct mechanical top opening or single data link control when passing through fire doors, but both methods have certain defects. Mechanical top opening fire doors usually do not close tightly, and after long-term operation Mechanical fatigue often has poor fi...
