How can Smart Prepayment Prepaid Meter Effectively Prevent Power Theft?

Many customers call us through our website to inquire about how Smart Prepayment Prepaid Meter can effectively prevent theft of electricity. Today, Measuring Devices Meter Wholesale will explain how prepaid meters can effectively prevent electricity theft.

Smart Prepayment Prepaid Meter

1. Card data security. Although the data of the ordinary memory card is encrypted and processed, the microcontroller in the IC card prepaid energy meter needs to complete a large amount of real-time work, so the data cannot be encrypted in a more complicated way. In addition, the ordinary memory card energy meter is not easy to implement the encryption of the table A card, but leakage or decryption will occur, and fake cards will appear, causing huge economic losses to the power supply department. Although the logical encryption card can realize one meter and one card, so that the system will not crash, but from the mouth of a memory oscilloscope, the key of each card can be easily obtained to achieve the purpose of stealing the meter. The initialization card and production card of the above two cards form a format, but after leaking or decrypting, it is not necessary to purchase a card and electricity (the meter returns to the production state, and the electricity is in the production state). These will cause huge economic losses to the power supply sector.

2. The IC card prepaid meter card reading microcontroller program was read, resulting in the encrypted elements being known by hackers. Many watch factories use 0TP records because of tight schedules or unstable production. Many microcontrollers can read the machine code of the solid state and its programs due to comparison during the programming process. The source program can be obtained by disassembling. By dividing the source program, the methods of stealing electricity and making fake cards can be mistaken.

3. The IC card prepaid energy meter and the card meter electronic module have poor anti-interference ability. If the electronic module card meter has poor adaptability to voltage changes (such as collisions caused by low voltage over a short period of time and abnormal voltage recovery), the interference ability is poor (such as electronic rectifiers, negative ion generators, ultraviolet disinfection lamps, and switches) due to power supply equipment, microwave ovens, or Large load switch, etc.) Poor anti-interference ability (such as welding, impact drill, transmitting radio, mobile phone, etc. near the meter), and no damaged electrical equipment, users will not buy card electricity, resulting in stealing unconsciously.

4. Card table to prevent problems leaving traces of malicious attacks. According to speculation and introduction, a malicious attacker would insert a metal sheet into the booth, causing a short circuit or short circuit in the booth. Some nodes burned the main IC with metal hooks and AC 220 volts, burned electronic modules with DC voltage power, and added electrostatic high voltage. . URE (such as gas ignition gas) is a main control IC method, such as smashing a trace of the instrument to achieve the purpose of stealing.
