The unattended system is installed in the coal mine substation, and the low-voltage and high-voltage power equipment of the substation and transformer are analyzed and monitored in a unified way. The cloud on the equipment can monitor the power operation data of the substation remotely through the mobile app terminal, mobile phone SMS, web screen, etc., which can realize the remote power shutdown, reduce the cost of enterprises, and improve the efficiency of power operation and maintenance management personnel. Cameras, door magnetic access control, temperature and humidity are installed in the whole substation to carry out real-time monitoring of the power operating environment of the coal mine substation to ensure that the operating environment of the substation is controllable; To achieve the ground substation unattended, reduce personnel and increase efficiency.

Traditional coal mine shift pain points:

To this end, Li ‘an Technology launched the e-Cloud – to provide a full set of solutions for the safety of coal mine electric power operation,

E-cloud — “Smart Power Internet of Things” aims to improve the safety of power operation and reduce operation and maintenance costs. It adopts modern information technologies such as the Internet of Things, cloud computing and big data to digitize and upgrade power equipment and operation and maintenance work. With the help of e-Cloud, it realizes intelligent power system and effectively guarantees the safe, controllable and efficient operation of power equipment.

Comprehensively solve the safety monitoring and fire prevention of power distribution system in industrial and mining enterprises. Real-time monitoring of power operation safety, security warning and alarm, real-time monitoring of electrical equipment data, such as current, voltage, power consumption, as well as environmental auxiliary control, real-time monitoring of temperature and humidity, access control system, high temperature warning, etc., through the Lian-Dianyi cloud platform. Improve the overall level of coal mine substation power safety risk management technology.

The intelligent unattended monitoring system of underground power supply in coal mine can realize the functions of unattended power supply and distribution system in coal mine substation, controllable and traceable, three early and one guarantee (early prediction, early detection, early elimination and safety protection), scheme assembly, remote closing and closing and power data analysis.

Functional application:

1. Visual display of electrical safety data

Through the function of three-dimension and system diagram, the visual monitoring of the equipment can be realized, and the electrical safety parameters, switch status and alarm information can be displayed intuitively.

It has the function of linkage warning and alarm. When an alarm occurs between electrical engineering equipment, a video will pop up at the same time to clearly query and confirm the site data information, and can notify the enterprise management staff through network phone, APP notification and other forms.

2. Refined energy management

Real-time power consumption accurate to hours, comprehensive statistics;

Power analysis in the day, accurately control the change of unit energy consumption;

Demand and extreme value management, to provide managers with unit energy load variation data;

According to the energy efficiency analysis, the comprehensive energy consumption and application of water, electricity and heat of the unit can be realized in accordance with the standard energy resource management working mode of the national first-level table, second-level table and third-level table.

3. Intelligent operation and maintenance to realize the process of work order

E-cloud has realized the intellectualization and retention of power system equipment operation and maintenance.

Maintenance personnel, from “work order generation – distribution – implementation – acceptance – evaluation – archiving”, form a one-stop service management system process, clear link, detailed process, comprehensive information technology, so that the coal mine substation power equipment through the electricity cloud to achieve the whole life of the same period management development.

4. Inspection management makes inspection work effective and comprehensive

Inspection work

Electronic id of equipment — background management plan — personnel field standard execution — the platform can automatically count and analyze the results.

The scientific testing standard configuration makes the testing content comprehensive and changes the testing work from technical personnel to responsible personnel.

Improve the safety and reliability of the unattended automatic monitoring system in coal mine substation.
