Abstract

The invention relates to a system of managing undermine worker and emergency searching people, belonging to the technique of electric information, which can solve the problems of present mine that without emergency search function. wherein, the wireless data collector uses wireless sensor to automatically collect the information sent from wireless data sender; said information via the transmission network is transmitted to the information process center; via data processing unit, said information will be displayed on the display unit; the emergency calling unit via started by person will send information; handle data collector can collect said information via wireless sensor to find the position of emergency calling unit. The invention can real-time find the dynamic distribution of undermine workers, and use the handle data collector to accurately search for the position of data sender.

Description

technical field [0001] The invention relates to a coal mine underground personnel management and emergency call and rescue system, which belongs to the field of electronics and information. Background technique [0002] At present, safety has always been an important issue in coal mine production. In order to reduce accidents and strengthen management, coal mines usually install a safety monitoring system mainly for underground personnel in coal mines. The existing safety monitoring system consists of a wireless coding transmitter, an underground data monitoring substation, a ground central station and a data transmission channel. The wireless coding transmitter sends out a radio frequency signal with representative identity characteristics, which is received by the data monitoring substation and then sent to the ground central station. The central station receives coded signals from data monitoring sub-stations, analyzes and processes them, and forms various files, so tha...
