Safety pre-warning system of mining equipment

Abstract

The invention discloses a safety pre-warning system of mining equipment, and is mainly characterized by comprising a power supply and distribution detection device, a motor state detection device, a distributed fiber temperature measuring device, a fiber grating temperature measuring device and a safety pre-warning platform, wherein the safety pre-warning platform comprises an industrial computer, a temperature measuring system software, a GSM (Global System for Mobile Communication) and an alarm device, the power supply and distribution detection device comprises a main switch board room measuring circuit, a power utilization device front measuring circuit and a power supply loop measuring circuit, the motor state measuring device comprises a power line, the distributed fiber temperature measuring device comprises a detection fiber and a fiber temperature measuring host, and the fiber grating temperature measuring device comprises a fiber grating sensor and a fiber grating temperature measuring host. According to the invention, by utilizing passive, electromagnetic interference resistant, electrically insulated and corrosion-resistant fiber grating technology and distributed fiber technology, a power carrier technology without laying an additional signal line is unnecessary, the system is safe and reliable, and provides guarantee for effective operation of the mining equipment.

Description

technical field [0001] The invention belongs to the technical field of mine safety production, in particular to a mine equipment safety early warning system. Background technique [0002] With the rapid development of social economy, the demand for energy is increasing day by day. Coal resources, as an important basic energy, play a pivotal role in the development of social economy. Therefore, the safe development of mineral resources has become an important factor affecting the rapid development of society. As the main part of mine safety production, mine equipment can operate normally during the working period, which directly affects the mine safety production and the output of mineral resources. [0003] In recent years, the state has paid more and more attention to safety production, but safety accidents have occurred frequently. With the increase of mining depth and the decrease of mine quality, the safety management of key areas such as mining, ground pressure, venti...

Problems solved by technology

[0004] The current status of mine equipment detection: the motors of the underground driving face are detected by motor status, but in view of the complex environment on site, the roadheaders and shearers move frequently, the laying of signal lines is easy to be broken, and the signal is not transmitted to the ground; cables and belts are used as mine One of the causes of the fire, the current protection is mainly based on point measurement and manual detection, the detection is incomplete, and the risk of fire is high; the state quantities such as switch contacts and connection temperature of the switch cabinet, frequency conversion machine and motor are not detected, due to production Explosion-proof is required in the process, and it is more sensitive to the faults of contacts and connection points. The faults of contacts and connection points may cause production stoppage accidents, and cause short-circuit explosions and flammable gas explosion accidents, which seriously affect personal and property safety. An important source of accidents that affect production safety; environmental testing such as underground roof pressure is mainly based on point measurement and manual measurement, and the detection is incomplete and has a large detection blind spot
