How to realize the remote management of smart meters?
With the continuous development of the industrialization process, bit by bit changes have penetrated into daily life. The era of 5G has arrived, and it will bring more changes to people's lives. As far as electricity meters are concerned, traditional mechanical electricity meters have gradually fallen behind the development of technology, and it is time to iteratively update to smart electricity meters. What are the important features of smart meters? It is real-time billing and remote management. Then let me focus on how to remotely manage the meter?
There are 3 major elements of the remote control system: smart meter, meter data collector and remote management software on the computer.
- Smart meter
Smart meters are the basis for remote management and the terminal equipment of the management system.The smart electricity meter first collects the user's current and voltage in real time by an A/D converter or a metering chip, and then analyzes, processes and calculates through a microprocessor, and then outputs the power and other content by means of communication and display. The electric meter has RS-485 communication and infrared communication interfaces to exchange data with external devices.
- meter data collector
The RS-485 communication interface of the smart meter is connected to the meter collector, which can simultaneously complete the data collection of multiple smart meters, run storage and send the data to the background server through GPRS communication, mainly to complete the data transmission to the upper level.
- remote management software on the computer
The remote management system performs statistical processing and analysis on the sent meter data, and performs personalized design functions according to different needs of users. It mainly realizes the remote control of the meter, remote meter reading, remote recharge, report printing and other operations, as well as the overall system running status is monitored, managed, stored, recorded, etc.
The smart meter developed and manufactured by Zhejiang Yongtailong Electronics Co., Ltd. has the characteristics of small size, good quality, light weight and easy installation.
Now introduces a three-phase four-wire smart meter with RS485 communication, which has the following characteristics:
- Load earthed detection
- Neutral Missing detection
- Terminal cover opening detection
- Strong magnetic detection
- High voltage anti-tamper(When the voltage circuit is damaged)
- RS 485 Communication with Modbus RTU protocol
- Support Two Tariffs
- This meter has white back light which increase the readability in the dark.
- 12 hours super capacitor as backup power supply to realize reading and event record during power failure
- Measure active and reactive energy
- Big LCD with 3 lines display
- Shunt Sampling
- Adopt Riveting proposal
- With Ultrasonic case and Anti-tampering screws.
