Abstract

The invention discloses a system and a method for distributed standby power supply management based on a LonWorks bus. The system comprises an above-ground system and an underground system, the above-ground system comprises a monitoring host and a signal converter, the monitoring host is used for displaying finally integrated information, and the signal converter comprises a neuron chip PL3120 and a LonWorks interface. The underground system comprises the LonWorks bus, a plurality of monitoring substations, standby power supplies for the monitoring substations and a plurality of LonWorks devices, wherein the LonWorks devices are used for acquiring thermal-electric parameters such as the temperature, the electric quantity and the voltage of the standby power supplies and actively transmitting the acquired information to the LonWorks bus. The LonWorks bus is used for the standby power supply management system for a coal mine monitoring system, the standby power supplies for the monitoring substations can be simultaneously managed, and the problems of long data polling acquisition period and poor communication instantaneity when the number of substations is large or a communication data packet is large as a master-slave polling mode is adopted in existing bus communication technology are solved.

Description

technical field

[0001] The invention relates to the field of backup power management systems, in particular to a backup power management system and method for a coal mine monitoring system. Background technique

[0002] my country is a country that uses coal as its main energy source. Continuously improving the level of safety production technology in coal mines has always been the common goal of the party, government and industry. At present, most coal mines in my country have installed and used various coal mine safety monitoring systems, including: coal mine gas monitoring system, coal mine downhole personnel positioning system, signal collection and closing system, roof dynamic monitoring system, etc. These monitoring systems are usually installed in a distributed state. In the alley under the well. In order to ensure the operational reliability of these monitoring systems, each monitoring system can work normally and stably when the coal mine power grid fails, and each ...
