Door-passing system and method for indoor inspection robot

Abstract

The invention discloses a door-passing system for an indoor inspection robot. The door-passing system for the indoor inspection robot includes a roller shutter door, the inspection robot, a roller shutter door controller, a roller shutter door motor, a roller shutter door wireless communication module, a laser emitter and a laser receiver, wherein the inspection robot includes a robot controller, a robot wireless communication module and an obstacle avoidance device. The invention further discloses a door-passing method for the door-passing system of the indoor inspection robot. The method includes the following steps of starting a door-passing mode when the inspection robot is close to the roller shutter door; confirming whether the roller shutter door is closed completely or not; emitting laser with the laser emitter; receiving the laser with the laser receiver; correcting the position through the robot wireless communication module; sending a door-opening instruction through the robot controller; opening the roller shutter door under control of the roller shutter door controller; and controlling the roller shutter door to close after the inspection robot passes the roller shutter door. Through the door-passing system and method for the indoor inspection robot, the inspection robot can automatically judge and correct its own position and have the automation control function for automatically controlling the roller shutter door to be opened and controlling the roller shutter door to close after passing the door.

Description

technical field [0001] The invention relates to the application field of an indoor inspection robot, in particular to an indoor inspection robot door-passing system and method applied to a power system. Background technique [0002] At present, none of the inspection robots used in power systems on the market has the function of automatically opening doors and passing through door openings indoors. There are no robots on the market that are used in inspections of hydroelectric power plants, nor are there any robots that are specifically used in indoor inspections to open doors. and door control system. [0003] Many existing inspection robots already include wireless communication modules and ultrasonic obstacle avoidance devices, so they have wireless communication and ultrasonic obstacle avoidance functions, such as AGV robots used in warehouses, etc. However, these existing inspection robots follow fixed tracks, The magnetic strip is pre-laid, or the ribbon is installed,...

AI Technical Summary

Problems solved by technology

[0003] Many existing inspection robots already include wireless communication modules and ultrasonic obstacle avoidance devices, so they have wireless communication and ultrasonic obstacle avoidance functions, such as AGV robots used in warehouses, etc. However, these existing inspection robots follow fixed tracks, Pre-laid magnetic strips, or installed ribbons, etc., the door opening has no door, and the robot directly passes through the door opening along the magnetic strip without opening the door

If this working method is applied to a hydropower plant, there will always be a hole in the door opening that the robot can pass through, which will bring safety hazards to the equipment and objects in the house, and will adversely affect the safety of the hydropower plant; since the door opening is always open, it is easy to cause equipment theft. At the same time, this pre-laid track operation method requires a large amount of work and is not flexible enough. Once the environment changes and the user's needs change, the route has to be re-assumed and holes will be re-dug on the wall.

[0004] In summary, existing power systems such as hydropower plants generally do not have indoor inspection robots, or even if existing inspection robots are used, they do not have the function of automatically opening and passing doors, so it is difficult to meet the needs of power systems for efficient inspections
