A certain mining plant utilizes multiple electric shovels for material transportation. During an energy consumption audit, it was discovered that these devices suffer from significant energy waste issues. On one hand, due to the large number of devices and substantial energy consumption, the overall energy usage is high. On the other hand, influenced by factors such as the mining and loading operation process and material transfer could be translated as coordination, each electric shovel experiences extended periods of standby time, resulting in high energy consumption without corresponding output and low energy efficiency. Therefore, there is a need for real-time monitoring and energy consumption management of these electric shovels to achieve energy conservation and efficiency enhancement.

In response, WideIOT offers an efficient and reliable IoT solution. By installing smart meters on each electric shovel and deploying industrial intelligent gateways to connect to the shovel's controller PLC and smart meters, real-time collection of information such as the shovel's operational status, process parameters, energy consumption data, and alarm data can be achieved. This data can then be connected to the factory management platform via 5G/4G/WIFI, enabling functions such as equipment monitoring, energy consumption management, and data analysis. This assists enterprises in making scientific and reasonable decisions, improving energy utilization efficiency and management levels.

Implemented Functions

1. Real-time Collection and Visualization: Real-time collection of the operational status and process parameters of electric shovels, with visual display on the factory management platform. This allows for quick understanding of information such as equipment operational status, voltage and current, online rate, failure rate, and the number of standby shovels.

2. Energy Data Monitoring and Reporting: Monitoring of data such as voltage, current, power, electricity consumption, and power factor for each electric shovel, with uploading to the factory management platform for categorized statistics. This enables the rapid generation of data reports and the formulation of energy-saving measures.

3. Flexible Alarm Configuration: The ability to flexibly set alarm rules, enabling automatic alarms when abnormal data is detected. Notifications can be sent via WeChat, SMS, email, etc., allowing for quick location, diagnosis, and implementation of measures to ensure production safety and energy-efficient operations.

4. Efficiency Assessment and Optimization: By comprehensively analyzing the operational and energy consumption data of electric shovels, it is possible to reasonably assess information such as equipment work efficiency, effective working time, and energy consumption per unit time. Quantitative indicators can be established, and factors influencing data changes can be identified, thereby improving utilization rates and energy efficiency.
