Problems solved by technology

These safety production monitoring and monitoring systems are mostly closed systems, and the communication protocols and information exchange standards used in the systems are all formulated by the manufacturers themselves, which are strictly confidential and incompatible with each other.
Moreover, the network structure and communication mode are diverse, and it is difficult to network between different systems, and it is difficult to achieve data sharing, resulting in repeated investment in equipment. Since each system needs to establish its own communication network, repeated laying of cables (optical cables), maintenance personnel Repeated settings, resulting in unreasonable allocation of enterprise resources, and the scalability of the system is limited
[0004] In addition, most existing mine production sites where sensing devices are installed are still connected to a terminal for monitoring and control by wired sensors, which increases costs and wastes resources and is not conducive to overall monitoring and control; and in most In the application, monitoring is a long-term process. In some places, due to environmental factors, sensors and control terminals cannot be laid, so a wireless temperature sensor network is required; and it must have the characteristics of large-scale deployment and small data volume.

According to the mine safety monitoring system based on the wireless network, real-time monitoring can be achieved and abnormal conditions are warned of through a warning device. Safety accidents are reduced as much as possible and the mine safety monitoring system has the advantages of being good in openness, high in real-time performance, good in safety and the like. A high-speed channel is provided for transmission of all sorts of detecting and monitoring systems. Information sharing of a sub-system is achieved as much as possible and extension of the system is facilitated.

Description

technical field [0001] The invention relates to a safety monitoring system, in particular to a wireless network-based mine safety monitoring system. Background technique [0002] Coal mine accident is a major problem that coal mine operations often face, and it seriously threatens the life and property safety of miners. Coal mine accidents are mainly caused by poor real-time recording of gas and air humidity, and failure to take corresponding measures in time at the critical point. If the gas concentration in the mine, the gas concentration in the mine, the air humidity, and the air flow in the mine can be recorded and analyzed in time, and the alarm can be given in time, the control part can take corresponding emergency measures according to the data in the mine, so as to avoid unnecessary accidents. . [0003] At present, the following monitoring systems are used for coal mine safety: comprehensive monitoring system of working face, monitoring system of environmental par...
