Intelligent pump room unmanned control system
Mine automatic drainage device is based on the actual situation of the underground, in the original facilities on the basis of automation transformation, so that the equipment in the case of unattended automatic operation and self-diagnosis of a system. Through the decision-making control of industrial computers, the operating status and operating process of the equipment are automatically detected and controlled to achieve the best working condition of the equipment, so as to effectively save energy, reduce labor intensity, reduce operating costs and extend the service life of the equipment. purpose.
The mine drainage system is responsible for the important task of discharging underground water inflow and is a key link in ensuring safe production in mines. The safe, reliable, and effective operation of various equipment in the drainage system is related to the production and safety of the entire mine.
The automatic drainage device for mining is a system that automatically transforms the original facilities based on the actual situation underground, so that the equipment can operate and self diagnose without human supervision. Through the decision control of industrial computers, the operation status and process of equipment are automatically detected and controlled to achieve optimal working conditions, thereby effectively saving energy, reducing labor intensity, lowering operating costs, and extending equipment service life.
The system integrates industrial control technology and modern software technology to ensure the stability and reliability of the system, and can be networked with the comprehensive automation system of the entire mine as a subsystem of the entire mine automation system.
Drainage equipment generally has high power and power consumption. Traditional drainage can only rely on manual control of pump start and stop, and cannot utilize drainage equipment and warehouse capacity to scientifically and reasonably schedule drainage volume and time. Therefore, traditional mine drainage methods generally have the disadvantages of high energy consumption, low efficiency, and high production costs.
Based on the above reasons, achieve automatic control of mine drainage and remote monitoring of the ground:
1. The system has the function of remote/automatic/local/maintenance control conversion, which can achieve unmanned control equipment.
2. The system monitors real-time parameters such as pump room video, equipment temperature (pump bearing temperature, motor winding and bearing temperature), flow rate, water level in the water tank, pressure (including pipeline pressure, vacuum pump negative pressure, etc.), vacuum degree, and drainage volume; Remote/local control of the start and stop of drainage pumps, as well as the opening and closing status of pipeline valves.
3. The system can display cumulative quantities such as drainage volume, active power consumption, and pump operation time, and has functions such as electricity load regulation and automatic pipeline network allocation, as well as automatic analysis and calculation of pump efficiency and process energy consumption.
4. By adjusting the start stop time to avoid peak electricity load periods, effectively peak shaving and valley filling can be achieved, saving electricity costs.
5. In automatic mode, the system can intelligently select the number of startup units, startup time, prioritize the operation of high-performance water pumps, and automatically start and stop pumps based on the water level in the water tank.
6. The system has alarm and parameter alarm limit setting functions (sensor disconnection alarm, communication status alarm, valve fault alarm, operating parameter alarm).
7. The system has shutdown protection and operation protection functions.
8. The system has the function of recording and querying monitoring parameter curves.

Intelligent control system for brine mining and transportation in salt mines
The intelligent control system for well and mine salt mining and brine transportation is a control system that integrates automation, intelligence, and information technology, designed specifically for the well and mine salt mining industry. The system utilizes advanced sensors, controllers, and actuators to achieve real-time monitoring and intelligent control of the entire process of brine mining in mines, improving production efficiency, reducing energy consumption, and enhancing safety.
Mining intelligent power monitoring system
The mining power supply monitoring system has achieved intelligent monitoring and management of the mine power supply system through advanced technological means. The system utilizes the RS485 communication protocol to efficiently exchange data between the mining power supply monitoring substation and the switch intelligent comprehensive protection unit. The monitoring substation is responsible for collecting the power parameters of the switchgear and transmitting the data to the ground monitoring system backend through the mining network switch. This backend not only has the ability to remotely control substation equipment, but also shares data to the comprehensive automation platform of the entire mine through OPC protocol, achieving network publishing and sharing of data.
