Underground robot communication control system based on Wifi

Abstract

The invention discloses an underground robot communication control system based on Wifi. The system is used for underground routing inspection and accident rescue and is particularly suitable for mines having accidents such as a gas explosion and a fire. An underground robot can reach a region where rescuers cannot reach as toxic and harmful gas exists, according to the rescue robot wireless communication control system, a new temporary Wifi network construction method is provided based on a multihop Wifi network technology, the wireless communication distance of the underground robot can be continuously increased along with advancing of the robot, and communication between the underground robot and control equipment is ensured. The problem that on the condition that an original wireless communication system in a mine cannot be used, the wireless communication distance between the underground robot and the control equipment is limited is solved.

Description

technical field [0001] The invention relates to a Wifi-based underground robot communication control system, and the system relates to the fields of wireless communication, 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 harmful gases at the accident site is ext...

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 traveling on the ground, such as wheeled, crawler, and serpentine, can communicate with the control equipment through wired communication, while robots that use flying travel should use wireless communication. At present, underground Wifi wireless communication networks have been widely used. , Wifi wireless communication has the characteristics of high data transmission, safety and reliability, flexible and convenient use, etc., but the communication distance is affected by factors such as transmission power and space blocking, which directly affects the working distance of the underground robot
