Prepaid electricity meters, also known as quantitative electricity meters or IC card electricity meters, not only have the metering function of regular electricity meters, but also require users to purchase electricity first before using it. If users do not continue to purchase electricity after using it, the power supply will be automatically cut off and stopped. Prepaid electricity meters, also known as quantitative electricity meters or IC card electricity meters, not only have the metering function of regular electricity meters, but also require users to purchase electricity first before using it. If users do not continue to purchase electricity after using it, the power supply will be automatically cut off and stopped. Used for measuring AC single-phase active energy with a rated frequency of 50Hz, achieving the management function of paying before using electricity. Advanced microelectronic technology is used for data collection, processing, and storage, and RF cards are used to transmit data. Its performance indicators comply with GB/T17215-2002 and GB/T18460.3-2001 standards. It has the characteristics of small size, high security, high reliability, and anti theft of electricity. There are two pre storage methods, one is code based and the other is write card based. The coding principle is that the management system combines user information and electricity purchase information to generate a set of encrypted codes, which are then input by the user into the electricity meter. After the meter is correctly decrypted, the pre stored electricity or amount is obtained and saved. Card writing mode: Write the pre purchased electricity or amount into a dedicated electronic card (memory), hand it over to the user to hold the electronic card and communicate with the corresponding electricity meter, and the pre purchased value will automatically be sent to the electricity meter. Electronic cards, also known as IC cards or power purchase cards, are made of specialized IC chips that have been specially packaged. Common power purchase cards are divided into contact and non-contact based on communication methods. Contact type cards include card cards and key cards, while non-contact types include radio frequency cards and remote control cards
