Description

Technical Field

[0001] The invention relates to the technical field of monitoring devices, in particular to a real-time online monitoring device for a coal mine substation. Background Art

[0002] Coal mine substation is an important part of the coal mine power supply and distribution system. It mainly converts the electric energy transmitted to the mining area into voltage and voltage and then transmits it to various equipment in the mine. Ensuring its safe and reliable operation is the basic guarantee for safe production in coal mines.

[0003] However, due to the wide variety of loads in coal mines, the wide distribution of regions, and the complex geological conditions of the workplace, there are many potential safety hazards. In this case, when a substation fails, there are problems such as long troubleshooting and power outage cycles, which seriously affects coal mine safety production.

[0004] With the gradual advancement of digital mine construction, coal mine users have an urgent need for "unmanned and patrolled" underground substations. However, the current coal mine substation monitoring system mainly monitors the power supply and distribution network in real time. At the same time, there are still safety hazards in coal mine underground substations. For example, the environmental factors and human factors affecting the coal mine underground substations have not been included in the real-time monitoring range of the system, and the safety monitoring in the substation needs to be improved. To this end, we propose a real-time online monitoring device for coal mine substations. Summary of the invention

The real-time environmental information collected specifically includes environmental temperature, humidity, air quality including gas concentration, coal dust, carbon dioxide, and volume parameters. The environmental comprehensive index is obtained by quantitative analysis. At the same time, the environmental assessment index is generated based on the environmental comprehensive index and sent to the management parameter analysis module;

[0009] The inspection monitoring module is used to monitor and collect the real-time inspection process in each time period in the underground substation of the coal mine. The specific collection of the real-time inspection process includes real-time monitoring of each inspection post, real-time investigation and monitoring of each hidden danger, and standardized monitoring of the operation process to ensure that the inspection responsibility is implemented to the corresponding personnel set. The inspection comprehensive index is obtained by quantitative analysis, and the inspection evaluation index is generated based on the inspection comprehensive index and sent to the management parameter analysis module;

[0014] As a further improvement of the present invention, a quantitative analysis of the substation environment state is performed based on real-time environmental parameters to obtain an environmental comprehensive index, which specifically includes:

[0015] Step 1: Monitor and collect the real-time ambient temperature in the substation to obtain a real-time ambient temperature parameter T;

[0050] As a further improvement of the present invention, an analysis is performed based on the environmental assessment index and the inspection assessment index, specifically:

[0051] When the environmental assessment index E is less than the set assessment threshold E', the environmental comprehensive index P is formulated as P = T × a1 / T' × a1 + RH × a2 / RH' × a2 + AQI × a3 / AQI' × a3 + dB × a4 / dB' × a4, and a comparative calculation and analysis is performed to obtain the environmental early warning influencing factors, and an abnormal instruction is generated. When it is greater than the set assessment threshold, a normal instruction is generated and sent to the execution terminal;

[0052] When the inspection evaluation index N is less than the set evaluation threshold N', the inspection comprehensive index M is formulated as M=G×c1 / G'×c1+V×c2 / V'×c2+U×c3 / U'×c3 for comparative calculation and analysis to obtain the inspection warning influencing factors and generate abnormal instructions.
