Wireless safety inspection system based on coal mine track electric locomotive power supply device

Abstract

The invention belongs to the technical field of coal mine track electric locomotive safety monitoring and relates to a wireless safety inspection system based on a coal mine track electric locomotivepower supply device. The system comprises a storage battery, a temperature detection module, a voltage detection module, a current detection module, a positioning module, a processor module, a data storage module, a wireless communication system and a monitoring terminal; the storage battery is in signal connection with the temperature detection module, the voltage detection module, the current detection module and the positioning module; According to the system of the invention, real-time on-line monitoring can be carried out on overcharge, overdischarge, short circuit, battery box overtemperature and other states of a single storage battery in the coal mine track electric locomotive power supply device, a single battery fault can be efficiently and accurately discovered, and early warning of the fault is realized, so that a battery pack is protected to the greatest extent, the service life of each battery is prolonged, and the cycle life of each battery is prolonged. More importantly, potential safety hazards of the power supply device are further eliminated, and meanwhile, data receiving accuracy is ensured through parallel work of multiple wireless communication modes.

Description

technical field [0001] The invention relates to the technical field of safety monitoring of coal mine rail electric locomotives, in particular to a wireless safety inspection system based on a power supply device of coal mine rail electric locomotives. Background technique [0002] In the production process of coal mines, underground locomotive transportation is one of the important and necessary modes of transportation. It not only undertakes the task of transporting underground personnel, but also undertakes important transportation tasks such as underground gangue, materials, equipment, etc., which is directly related to coal mine production. efficiency and effectiveness. Importantly, it is also a major source of hidden dangers in coal mine safety production. According to the statistics of major coal mine accidents in the country, mine transportation casualties in my country account for about 26% to 30% of the total accidents, ranking second in all kinds of personal casu...

Problems solved by technology

[0003] In order to eliminate the potential safety hazards caused by cable temperature under abnormal conditions, the traditional method is to increase the cross-sectional area of ​​cables to realize the dispersion of transmission energy. There has not been a precedent in coal mines. The main reason is that the transmission of energy information and the connection between equipment and devices are likely to cause safety hazards, and the safety elements are strict to an absolute degree.

However, in the operation of underground locomotives, long-term use of the power supply will often cause a series of problems, such as overheating of the battery box, overcharging and overdischarging, and short circuit, which will easily lead to damage to the power supply unit and reduce the service life. More importantly, the power supply unit Security risks caused by exceptions
