Underground robot communication control system based on wireless sensor network

Abstract

The invention discloses an underground robot communication control system based on a wireless sensor network. The system is applied to underground polling and accident rescue, and is particularly suitable for mines in which accidents such as gas explosions and fire disasters happen. An underground robot can reach areas with toxic and harmful gas which are unreachable for rescue workers. A rescue robot wireless communication control system is characterized in that on the basis of a multi-hop wireless sensor network technology, a method for building a new temporary wireless sensor network is provided in order that a wireless communication distance of the underground robot can increase continuously along with the advancing of the robot, and communications between the underground robot and control equipment are ensured. Through adoption of the underground robot communication control system, the problem of limited wireless communication distance between the underground robot and the control equipment under the condition that an original wireless communication system in a mine cannot be used is solved.

Description

technical field [0001] The invention relates to an underground robot communication control system based on a wireless sensor network, and the system relates to the fields of wireless sensor network technology, video and audio collection and the like. Background technique [0002] With the improvement of mechanization, informatization and automation of various mine production, the safety production situation of mines in China has improved year by year, and various accident rates and death rates have dropped significantly. However, the underground production environment is complex, and various accidents are inevitable. After the accident, timely grasping the situation of the underground accident scene is the key to correct and effective rescue and reducing casualties. Accidents such as underground gas explosions and fires will produce a large amount of CO, CO 2 , CH 4 and other toxic and harmful gases consume a large amount of O 2 . When the concentration of toxic and harm...

AI Technical Summary

Problems solved by technology

Since the current underground wireless communication access equipment needs to be connected to the power supply system and communication optical cables or cables, when an accident occurs, the original wireless communication system in the roadway cannot be used, and the underground robot must have its own communication system for communication.

Robots that travel on the ground, such as wheeled, crawler, and snake, can communicate with the control equipment through wired communication, while robots that use flying travel should use wireless communication. At present, underground wireless sensor networks have been widely used. Wireless sensor network communication has the characteristics of low cost, flexible and convenient networking, etc., but the communication distance is affected by factors such as transmission power and space blocking, which directly affects the working distance of underground robots.
