1. Concept of remote meter reading system
The remote meter reading system aims to realize real-time and reliable remote reading of data, not limited to power consumption, but also to make statistics on more complex data, such as voltage imbalance rate and harmonics.
2. Remote meter reading system framework
The frame diagram of remote meter reading system is as follows. The electricity meter belongs to the bottom field equipment layer.
1) Application layer of energy efficiency management
The human-computer interaction center can complete energy monitoring, energy consumption analysis, comparative ranking, energy management and online reporting of energy data through large screen, PC, mobile notebook, mobile phone, tablet and other visual interaction tools.
2) ECS layer
As the brain of the energy management system, it integrates three functional centers: data server, interface server and application server, which can process various data transmitted by the network communication layer, and store, forward, analyze and manage the data.
3. Network communication layer
RS485, Ethernet GPRS, 4G, NB ot. lora, Zigbeeifi and other transmission modes are used on the site to connect the power acquisition module in the area to the corresponding communication management machine; Each communication manager connects to the server through the user LAN.
4) Field equipment layer
The field equipment layer is responsible for collecting and uploading the parameters of electricity, water, gas and warm environment. The field equipment layer is composed of multi-function electric energy meter, multi-function electric energy meter, intelligent water meter, intelligent gas meter, temperature and humidity sensor and other acquisition equipment.

3. What is a rail type electric energy meter?
The rail electric energy meter is a terminal electric energy meter. The traditional wall mounted installation is widely used, which has the disadvantages of large volume and inconvenient installation. However, the rail type ammeter adopts modular design, which has the advantages of small size, easy installation, easy networking, etc., and is easy to realize the measurement of terminal lighting energy, which is convenient for the transformation of the lighting system to install electricity meters.
4. When does the remote meter reading system choose the rail type electric energy meter?
Due to its miniaturization structure, the rail type watt hour meter can be conveniently used together with the miniature circuit breaker and installed in the terminal lighting box. It provides an effective solution for the power metering of low-voltage lighting terminals. It can be widely used in buildings, shopping malls, exhibition centers, schools, airports, ports and factories.
When the installation space of the meter is not large enough and the installation is difficult, the rail type meter can be selected, and different types of rail type meters can be selected according to the data type of meter reading.
