Compared with the old-fashioned IC card prepaid meter, the remote-controlled meter is more intelligent and convenient, and its remote charging without media is a trick! This kind of electric meter has five features:
1. APP, PC multi-platform, remote operation anytime, anywhere.
2. Support remote meter reading, recharge (Alipay, online banking), reset, power on and off.
3. In case of low battery, it will alarm and trip automatically in case of arrears.
4. Self-service recharge by tenants, intelligent management by landlords.
5. Set the power threshold to avoid potential safety hazards.

With so many smart functions, let's take a look at its system principle.
Principle of Intelligent Prepaid Meter System
Prepaid electricity meters generally consist of metering chips, high-speed data processors, data interfaces, communication modules and other equipment. Under the control of the high-speed data processor, the real-time parameters of the grid operation are accurately obtained through the metering chip, and the data is processed according to the corresponding tariffs. The results are stored in the data memory, and information and data are provided to the external interface at any time exchange.
Power-off principle of smart prepaid meters: The built-in magnetic latching relay in this type of meter automatically realizes the function of pulling and closing, and the meter can directly cut off the power or switch on the power. In this way, the power supply will be automatically cut off after the prepaid power is used up, and the electricity will be used after payment, effectively solving the problem of difficult charging.
The current artificial intelligence technology has been put into use in many industries. It can be said that the use of smart devices and big data to solve the problems of industry development has become the first choice of many companies now. It promotes the transformation of enterprises and social growth through better services and more efficient work efficiency. Zhejiang Yongtailong Electronics Co., Ltd. has been keeping up with the pace of the times, has been working hard in the field of smart meters, and has the courage to innovate in technology and applications.
