Multi-network integration mine wireless Internet of Things communication system

Abstract

The invention relates to the technical field of wireless Internet of Things, and only discloses a multi-network integration mine wireless Internet of Things communication system. The multi-network integration mine wireless Internet of Things communication system comprises a ground monitoring center, mine intrinsic safety type communication nodes, a mine intrinsic safety type personnel tracking andpositioning card, a mine intrinsic safety type miner positioning communication terminal and a mine intrinsic safety type signal repeater; the ground monitoring center is composed of a system server,a gigabit switch, a radar transceiver and a UPS power supply; the ground monitoring center is mainly used for receiving, processing and storing data sent by an underground wireless network, and displaying processed data on display equipment of the monitoring center in real time; and the communication nodes are wirelessly connected and automatically networked. Equipment circuits adopt low power consumption design, and the battery replacement cycle is long. The multi-network integration mine wireless CommTrac Internet of Things system has the current international advanced level and is sensitiveand accurate in monitoring, real-time and visual in map display, stable and reliable in performance and easy to use and maintain.

Description

technical field [0001] The invention relates to the technical field of wireless internet of things, in particular to a multi-network fusion mining wireless internet of things communication system. Background technique [0002] The existing systems on the market are complex and cumbersome to install: the underground part of the existing coal mine safety monitoring system generally consists of sensors, substations, power boxes (or electric control boxes), master stations (or transmission interfaces), remote terminals, network interface cables and junction box etc. Some of the equipment needs to use flameproof shells, which are very heavy and troublesome to carry. [0003] The various parts of the underground are connected by explosion-proof cables, requiring more than a dozen construction workers to carry out complex installation and construction of equipment and cables. Due to the complex construction conditions underground, there are many unforeseen factors, and the constru...

AI Technical Summary

Problems solved by technology

[0003] The various parts of the underground are connected by explosion-proof cables, requiring more than a dozen construction workers to carry out complex installation and construction of equipment and cables. Due to the complex construction conditions underground, there are many unforeseen factors, and the construction period is long. If the existing coal mine safety monitoring system fails , since each part is connected by wire, it is necessary to check the equipment and cables near the fault point one by one to troubleshoot

The efficiency of troubleshooting is low, which affects the production of coal mines

[0004] The connection between each equipment of the coal mine safety monitoring system needs to be debugged one by one before it can be used. The operation of the system is complicated. The existing underground personnel positioning system can only count the approximate location of the personnel, which is not conducive to the communication and rescue of personnel. When changing the working face, Due to the cumbersome equipment and complicated wiring of the coal mine safety monitoring system, equipment and cables are often abandoned due to construction costs, and the equipment reuse rate is low

[0005] In the event of a mine disaster, due to underground power failure, the coal mine safety monitoring system cannot work, and cannot detect the location of underground personnel and harmful gas data in time, and cannot provide assistance for mine rescue.
