1、 Product Overview and Core Positioning
4G metering instruments are industrial grade intelligent power meters based on mobile communication networks.
• Core function: Accurate measurement and metering of power parameters.
Core feature: Built in 4G communication module, no additional gateway required, data can be directly uploaded to the cloud platform or monitoring center through 4G network.
Core value: It solves the limitations of traditional electricity meters that require wiring or rely on Wi Fi, making it particularly suitable for application scenarios where deployment is decentralized, there is no local network, and on-site wiring is difficult, achieving rapid deployment of "power on, go online".
2、 Main product model series
Ankerui offers 4G communication versions for multiple series of electricity meters, mainly covering the following models:
1. AEM series (network power meters):
•型号示例: AEM72-4G, AEM96-4G, AEM320-4G 等。
• Features: This is the main series with comprehensive functions, capable of measuring all power parameters (three-phase/single-phase), energy metering (four quadrant), demand statistics, and supporting 2-31st harmonic measurement. Usually provides multiple specifications (such as direct access, via transformer access).
2. ADW series (wireless multifunctional power meter):
•型号示例: ADW300-4G, ADW350-4G 等。
• Features: Designed specifically for the Internet of Things, in addition to basic power parameter measurement, many models also support multi rate energy statistics, DC measurement (ADW350), and other functions, making them very suitable for energy management and sub metering for industrial and commercial users.
3. ADL series (rail mounted energy meter):
•型号示例: ADL200-4G, ADL400-4G 等。
• Features: Installed with standard DIN35mm guide rails, it is compact in size and easy to install. It is mainly used for energy metering and monitoring of branch circuits, such as floor distribution boxes and production line equipment in shopping malls and factories.
3、 System composition and working principle
1. Terminal equipment (4G meter itself):
Installed in the distribution box, collect raw data such as voltage and current on site, calculate and process them to obtain the required power parameters and energy values.
The built-in 4G CAT1 communication module (low power consumption, wide coverage, moderate cost) automatically dials to access the mobile public network.
2. Data transmission network:
• The 4G network of the operator (China Mobile, China Unicom, China Telecom) is used as the transmission channel, and data is accessed to the Internet through the base station.
3. Monitoring platform:
Acrel Cloud: This is a commonly used method. After the electricity meter is powered on, it automatically registers and connects to the Anke Cloud platform. Users can access data through PC web pages, mobile apps, and WeChat mini programs without the need to build their own servers.
Third party platforms or local monitoring systems: The electricity meter also supports sending data (usually in JSON format) to the user's designated private cloud, public cloud (such as Alibaba Cloud, Tencent Cloud), or local energy monitoring system through standard network protocols such as MQTT, HTTP, TCP/IP.
4、 Core functional features
1. "Cloud end" direct communication: No gateway collection required, simplifying system structure, reducing costs and fault points.
2. Minimalist deployment: Only wiring (power and CT) is required on site, and the network will automatically connect after power on, greatly reducing installation and debugging time.
3. Remote operation and maintenance: The platform allows for remote parameter settings, software upgrades, and fault diagnosis of instruments, resulting in high operation and maintenance efficiency.
4. Multi scenario applicability: not limited by geographical distance and local network environment, especially suitable for:
Distributed sites: communication base stations, photovoltaic power stations, wind power stations, charging piles, outdoor box transformers.
Mobile or temporary equipment: temporary power supply for construction sites, ship power supply, containerized equipment.
• LAN free locations: renovation of old buildings, scattered shops, agricultural irrigation pump stations.
5. Stable and reliable: Industrial grade chips and communication modules are used to adapt to high temperature, high humidity, and electromagnetic interference in electrical environments.
6. Data Security: Supports SSL/TLS encrypted communication to ensure the security and privacy of data during transmission.
5、 Typical application scenarios
Energy management for industrial and commercial users: Conduct unified electricity monitoring and energy consumption analysis for stores, factories, and office buildings scattered in different areas.
Photovoltaic operation and maintenance monitoring: Monitor the power generation efficiency, grid connection point power quality, and grid connected electricity of distributed photovoltaic power plants.
• Operation and management of charging stations: As the internal measurement of DC charging stations or the superior measurement of AC charging stations, it realizes remote management of electricity consumption and costs.
Smart City/Internet of Things: Used for power monitoring of urban infrastructure such as smart street lights, smart manhole covers, and 5G micro base stations.
Environmental protection and energy-saving projects: As a key data collection device for energy auditing and energy-saving renovation, it verifies the energy-saving effect.
6、 Value brought to users
Low cost deployment: saves a lot of procurement and installation costs for communication cables and gateway equipment.
Efficient operation and maintenance: Achieve unmanned operation and remote completion of most management tasks, reducing manual inspection costs.
Data driven decision-making: By providing accurate energy consumption data, users can discover areas for energy efficiency improvement and achieve energy conservation and consumption reduction.
• Safety warning: Real time monitoring of abnormal electrical parameters to prevent electrical fires and equipment failures.
