Problems solved by technology

However, the power consumption of broadband communication equipment based on wireless Mesh networks is relatively large, and the working power or battery capacity of these system equipment is very limited. How to ensure their standby life as long as possible is a challenge for wireless Mesh network technology in coal mine disaster relief communication applications. the puzzle
At present, the 48-hour emergency rescue communication guarantee time can be met internationally, but this is still far from the 72-hour golden time for life rescue.

Abstract

The invention provides an energy-saving mining multimedia emergency rescue communication system, which comprises the core equipment of a mining multifunctional wireless Mesh gateway, a mining multifunctional wireless Mesh router and a multimedia service server, wherein each of the gateway and the router is provided with a master control system board and a WiFi Mesh system board; the master control system board is provided with a master controller of which a power control end is connected with a WiFi Mesh system power input gating module; and the WiFi Mesh system board is provided with a subcontroller and a WiFi intelligent access card. The system is characterized in that: the master controller of the gateway is provided with a gateway energy-saving control system, while the master controller of the router is provided with a routing energy-saving control system. The gateway energy-saving control system is organically integrated with the routing energy-saving control system to implement an energy-saving control method for controlling the working state of a high-power consumption WIFI system by using a low-power consumption embedded subsystem and combining a software dormancy mechanism and a hardware dormancy mechanism, and effectively prolong the standby time of the equipment.

Description

Technical field [0001] The invention relates to the technical field of multimedia wireless communication in mines, in particular to an energy-saving multimedia emergency rescue communication system for mines. Background technique [0002] According to the current emergency rescue communication system and its technology development trend for the mine rescue team, the mine emergency rescue communication is mainly based on the wireless network-based emergency communication system and the wired network-based emergency dispatch communication system, as well as the combination of the previous two methods. Wired and wireless hybrid emergency communication system. According to the transmission service type and transmission bandwidth of the mine emergency rescue communication system, there are mainly narrowband emergency communication systems based on low-rate data transmission and broadband multimedia emergency communication systems based on high-rate data transmission. [0003] Early min...
