Underground monitoring network system based on ZigBee network nodes

Abstract

The invention discloses a monitoring network system based on ZigBee network nodes, which comprises a ground safety monitoring system, a ZigBee wireless sensor network and a CAN network, wherein the ground safety monitoring system collects and analyzes various kinds of underground data, judges an underground safety condition according to the underground data, decides a dealing measure and issues early-warning information, the ZigBee wireless sensor network collects the parameters of an underground environment and the data of personal information, and the CAN network is connected with the ground safety monitoring system and the underground ZigBee wireless sensor network; and information issued by the ground safety monitoring system to an underground part is transmitted to the ZigBee wireless sensor network. The invention adopts a wireless sensor network technology, i.e. a ZigBee and is a self-organization wireless network taking data as a center, and nodes in the network are dense, have large number and are disposed at a very extensive area; the topological structure of the network is dynamically changed, and the network has the properties of self organization and self regulation; and the invention combines the function of the data transmission mode of a traditional coal mine safety system and has very good flexibility, extensibility, self-organization capability of the network, low cost, low power consumption and high safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of underground coal mine safety monitoring, in particular to an underground monitoring network system based on ZigBee network nodes. Background technique [0002] As my country's basic energy and important raw materials, coal occupies an extremely important strategic position in the national economy. In my country's energy structure, coal accounts for about 70% of my country's primary energy production and consumption structure, and it is expected to still account for more than 50% by 2050. Therefore, coal will still be the main energy source in my country for quite a long time, and the energy structure dominated by coal will be difficult to change in the short term. [0003] Recently, with the increasing demand for coal, coal mine accidents in our country are on the rise again, and the safety situation of coal mines is worrying. my country's coal mine safety information technology is not highly networked,...

Problems solved by technology

Due to the limited number of such specialized personnel, and considering the randomness of inspectors' inspections of various areas, it is impossible to cover all areas underground

Moreover, when the gas content in the air is high, the oxygen content can be reduced, causing suffocation, and personally arriving at the information collection point to collect gas information, there are still personal safety issues for the collection personnel
