Remote Meter Reading Principle of Smart Electric Meters in Campus Renovation?

1. Data Collection: Sensors and Metering Chips

Real-time monitoring of electricity consumption data:

Smart electric meters are equipped with high-precision sensors and metering chips, which can collect parameters such as current, voltage, power, and electricity consumption in real time, with an accuracy error usually less than ±0.5%.

Data storage and preprocessing:

After being processed by a microprocessor, the collected data is stored according to time series or event-triggered rules (such as daily timing, sudden increase in consumption), and structured data packets are generated for upload.

2. Data Transmission: Supported by Wireless Communication Technology

Selection of communication protocols and networks:

Smart electric meters adopt Low-Power Wide-Area Network (LPWAN) technologies, such as NB-IoT (Narrowband Internet of Things), 4G, or LoRaWAN. These technologies ensure wide signal coverage and strong penetration, adapting to the complex building environment of campuses.

Data encryption and secure transmission:

Data is transmitted to the cloud server through the TLS/SSL encryption protocol to prevent eavesdropping or tampering, and ensure privacy and data integrity.

3. Data Processing and Analysis: Empowered by Cloud Platforms

Automatic parsing and anomaly detection:

After receiving the data, the cloud server parses and verifies it through algorithms, identifies abnormal electricity consumption behaviors (such as short circuits, illegal use of high-power equipment), and triggers alarm or power-off instructions.

Multi-dimensional data analysis:

Combined with big data technology, it analyzes electricity consumption trends, peak-valley distribution, and energy consumption hotspots, generates visual reports, and assists schools in optimizing energy allocation.
