1. Product Background

The energy consumption monitoring and management system relies on information technologies such as computer networks, wireless communication, and metering collection. This system targets energy mediums such as electricity and water, establishing an energy consumption monitoring center for enterprises, industrial parks, and other energy-consuming units. It enables real-time collection, measurement, and analytical calculation of electricity and water usage, reflecting dynamic data changes and storing historical data for querying, thus achieving digital, networked, and visualized energy and energy-saving management. It helps factory managers understand energy costs, manages control in real time, improves management efficiency, reduces operating costs, and achieves scientific energy use and energy conservation.

Energy consumption monitoring systems have wide applications, including hospitals, residential communities, schools, industrial factories, office buildings, and commercial complexes.

2. Product Features

The energy consumption monitoring system consists of three components: the metering layer, information management layer, and application management layer. The metering terminals include electricity, water, and gas meters, while the gateway collects data from these meters. The system provides statistical analysis, presenting intuitive data visualization to management staff, allowing them to understand real energy consumption data, automatically analyze high energy consumption points, and provide energy-saving solutions for refined management.

Functions of the Energy Consumption Monitoring System

• Real-time Monitoring: Continuously monitors the usage of all users within the system, providing real-time data feedback on energy consumption.
• Data Analysis: Detailed recording and analysis of electrical usage in each circuit, displayed in tabular format, with the ability to switch to bar charts, line graphs, and other intuitive formats for comparison.
• Data Statistics: Offers comprehensive classified and detailed energy consumption statistics reports, allowing users to print daily, monthly, seasonal, and annual electricity consumption statistics at any time.
• Fault Alarm: The system issues voice alerts when there is an unexpected change in electricity load, with alarm messages sent to relevant personnel via SMS.
• Automatic Energy-saving Report Generation: Staff can review real energy consumption data for public buildings, automatically analyze high energy points, and propose energy-saving solutions for refined building management.

3. Product Design Challenges

Hardware Compatibility and Standardization: The energy consumption monitoring gateway needs to connect multiple types of sensors and metering devices from various manufacturers, using different communication protocols and data formats. Therefore, the gateway’s hardware design must consider broad compatibility and standardized interfaces for seamless device connections.

Stability and Reliability: The monitoring gateway operates 24/7, requiring high stability and reliability in hardware design, including the selection of high-quality components, proper heat dissipation design, and effective fault detection and recovery mechanisms.
