Downhole emergency rescue broadcasting system and broadcasting control method thereof

Abstract

The invention discloses a downhole emergency rescue broadcasting system and a broadcasting control method thereof and relates to the field of broadcasting communication. The system comprises a host system and a switch which are located on the ground, and a plurality of downhole flameproof players, a downhole switch and an environment collection device. The host system is connected with the switchthrough utilization of a network cable. A host ARM processor is set in the host system. The host ARM processor is used for obtaining an operation instruction and converting the operation instruction into a CAN command. The downhole switch is connected with the plurality of flameproof players and the environment collection device through utilization of an Ethernet ring network. Playing ARM processors and address setting devices are set in the plurality of flameproof players. According to the system and the method, the host system is associated with various control hosts on the ground, a CAN busconnected with the ground switch and the downhole switch, the plurality of flameproof players are connected through utilization of the Ethernet ring network, and regional management is carried out onthe players through utilization of the address setting devices, so safety management and dispatching and commanding capabilities are improved.

Description

technical field [0001] The invention belongs to the field of broadcast communication, and in particular relates to an emergency rescue broadcast system for underground and a broadcast control method thereof. Background technique [0002] my country is a country rich in coal, poor in oil, and low in gas. This characteristic determines that coal will occupy a dominant position in primary energy production and consumption and will not change for a long time. At present, my country's available coal reserves account for about 11.67% of the world's coal reserves, ranking third in the world. my country is the largest coal-producing country in the world today, and its coal production accounts for more than 35% of the world's total. my country is also the country with the largest coal consumption in the world. Coal has always been the main energy source and important raw material in our country. However, the automatic mining of coal mining enterprises in my country is still relative...
