Abstract

The invention provides an underground positioning and safety monitoring system on the basis of a communication network, which comprises a ground control center, a plurality of personnel positioning terminals, a plurality of short message positioning terminals, a plurality of voice communication positioning terminals, a plurality of wireless positioning base stations and a base station gateway. The personnel positioning terminals carry out timing on broadcast signals by broadcast bands; the base station gateway or the wireless base stations receive the broadcast signals, acquire contents and the signal strengths of the broadcast signals, encapsulate information according to a protocol, transmit the information to the ground control center by the network for positioning processing, and acquire corresponding position information; meanwhile, a mobile node adopts a timing POLL mechanism to receive a downlink command of a data center so as to realize bidirectional data transmission, and a network base station controls illumination equipment to realize energy-saving production according to existence or non-existence of the mobile node in a current region. The underground positioning and safety monitoring system has the characteristics of high reliability, simplicity in construction and accuracy in position.

Description

technical field [0001] The invention relates to the technical field of mine personnel positioning and safety monitoring, in particular to an underground positioning and monitoring management system and method based on wireless communication. Background technique [0002] Environmental and safety monitoring of coal mine production is a crucial issue in the production process of the coal mine industry. In addition, production efficiency and energy-saving management are also key links for coal enterprises to improve economic benefits. At present, my country's coal enterprises have successively adopted management information systems, environmental monitoring systems, personnel positioning management systems, etc., but these systems generally start from a single business and are separated from each other. Personnel positioning, environmental monitoring, equipment control and other aspects are the key business links of underground positioning and safety monitoring system. Analysi...
