What Are the Functions and Communication Methods of Smart Meters?
The electric energy meter is an important instrument for electric energy measurement. It was used earlier in my country and has a long history of use. With the continuous development of my country's economy, more and more applications of electric energy have been used, and electric energy has become an indispensable part of human social life and development. important energy sources and the requirements for the accuracy of electric energy metering are getting higher and higher. With the development of science and technology, smart electric energy meters have gradually entered the homes of ordinary people as a substitute for traditional electric energy meters. What are the functions and communication methods of smart meters?
1. What are the functions of a smart meter?
The original distribution system of the smart meter terminal realizes remote electronic control, billing, and recharging, and security control. When the promotion of apartments is customer service-oriented, the systematic application of smart meters can solve:
1). Disputes over the calculation of electricity bills due to breach of the lease.
2). Solve the problem of ladder price calculation.
3). Reduce the manpower input for the operation of fee payment.
4). Reduce the cash settlement between offline households and housekeepers.
5). Improve the service perception of residents.
6). Solve the hidden safety problems of uncontrollable power consumption.
2. What is the communication method of the smart meter?
1). RS485 communication:
Hardware: RS485+energy meter+ collector
Applicable scenarios: It is suitable for scenarios where electricity meters are centrally installed, such as residential buildings, office buildings, schools, etc.
Features: One collector can read the data of 32 electricity meters, with fast transmission speed, high data stability, and low overall cost.
2). NB-IOT/4G full wireless communication
Hardware: electricity meter + NB-IOT/4G wireless module (the module is built into the electricity meter)
Applicable scenarios: It is suitable for scenarios where electricity meters are installed separately, such as supermarkets, industrial parks, villas, etc.
Features: The meter has a built-in NB-IOT/4G wireless module, which requires no wiring or acquisition equipment, and can be installed quickly without being restricted by multiple stations.
3. RF wireless radio frequency communication
Hardware: electricity meter + RF module + collector (the module is built in the electricity meter)
Applicable Scenarios: Applicable to scenarios where electricity meters are installed in a distributed manner, such as shops, parks, factories, etc.
Features of the scheme: No communication costs, no wiring, stable signal transmission, strong anti-interference ability, and one collector can read the data of 128 electricity meters.
