WIFI (wireless fidelity) technology based underground intelligent mobile terminal system

Abstract

The invention provides a WIFI (wireless fidelity) technology based underground intelligent mobile terminal system which comprises an aboveground application server, an aboveground database server, a PC (personal computer) control end, a switchboard, a router, underground wireless APs (access points), and a mobile terminal with a WIFI function, wherein the aboveground application server is used for implementing the connection and data transmission with the mobile terminal, and implementing the positioning services of the underground personnel and a production and safety information search service function; and the mobile terminal can establish a connection with the aboveground application server through the WIFI module so as to inquire underground production and safety information through accessing the application server, can regularly scan and send signal strengths of surrounding underground wireless APs to the aboveground application server, and can inquire the current position and call a roadway map so as to achieve an escape navigation function. The mobile terminal system disclosed by the invention integrates functions such as bidirectional communication, safety and production information acquisition and bidirectional transmission control, personnel target orientation, escape navigation, and the like, therefore, the mobile terminal system provides important guarantee for the production safety of underground operations.

Description

technical field [0001] The invention relates to an intelligent communication system for an upper and lower well, in particular to an intelligent mobile terminal system for an underground based on WIFI technology. Background technique [0002] In the process of coal mine production, when various accidents occur, in order to be able to communicate with each other about the disaster situation at the underground site and the safety of the operators themselves and organize rescue in time, it is necessary to establish a complete communication system above and below the mine. [0003] The existing underground intelligent mobile terminal systems mainly include the following types: [0004] One is a communication system composed of PHS mobile phones, wireless base stations, and digital program-controlled switches. Workers in the mine carry PHS mobile phones. There are many base stations distributed underground, which can realize the interconnection between underground base stations...

AI Technical Summary

Problems solved by technology

[0008] (1) The first type of system can realize the voice and SMS communication between the underground and the underground, but it cannot realize the functions of personnel positioning and disaster escape navigation. This system can realize the transmission of voice or text information from the underground to the underground through different underground terminals , the disadvantage is that the information transmission from the well to the downhole cannot be realized

On the one hand, the underground staff cannot know the concentration of gas, oxygen, and carbon monoxide in the mine in time, and on the other hand, they cannot receive the coordinates of the location server for location positioning, so they cannot know their exact location. Downhole location, the escape route cannot be correctly judged, and there are potential safety hazards

[0009] (2) The second special personnel positioning system can realize the positioning of the underground staff in the above-ground dispatching room, but because the miners carry portable transmitters, which have a simple structure and cannot receive data, the underground personnel cannot One is to check your location information in time. Once you encounter a disaster situation, you cannot choose to escape and drop off in time.

In addition, the specific working environment information in the mine cannot be sent to the underground staff in time by the server on the mine, which poses a safety hazard

[0010] (3) The underground emergency paging system, underground personnel tracking system and wireless mine management and safety system developed abroad have been put into use abroad, and the communication terminal has the defects of single function and small channel capacity

On the other hand, the cost of introducing and using is relatively high
