How Prepaid Electric Meters Can Effectively Prevent Electricity Stealing
Many customers have called through our website to inquire how prepaid meters can effectively prevent electricity theft, so today we will explain how prepaid meters can effectively prevent electricity theft.
1. Security of card data. Although the data of the ordinary memory card is encrypted and processed, the microcontroller in the IC card prepaid electric energy meter needs to complete a lot of real-time work. So, the data cannot be encrypted in a more complex way. In addition, it is not easy for ordinary memory card electric energy meters to realize the encryption of the meter A card, but there will be leakage or decryption, and false cards will appear, causing huge economic losses to the power supply department. Although the logical encryption card can realize one table one card, so that the system will not crash. But from the mouth of a memory oscilloscope, the key to 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 leakage or decryption, there is no need to purchase the 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 meter reading microcontroller program of the IC card prepaid meter card is read, resulting in the encryption element being known to the hacker. Due to tight schedules or unstable production in many watch factories, card watch microcontrollers use OTP records. And many single-chip computers can read the machine code of the solid state and its program due to the comparison during the programming process. The source program can be obtained through disassembly, and the methods of stealing electricity and making fake cards can be mistaken by dividing the source program.
3. The IC card prepaid electric 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 collision caused by short-term low voltage and abnormal voltage recovery), and poor interference ability (such as electronic rectifiers, negative ion generators, ultraviolet disinfection lamps, with switches). Due to poor anti-interference capabilities such as power supply equipment, microwave ovens or large load switches (such as welding, impact drills, radios, mobile phones, etc. being transmitted near the meter), and no damaged electrical equipment, users will not buy card electricity, resulting in unconsciousness in steal.
4. The card table prevents the problem from leaving traces of malicious attacks. It is speculated and introduced that malicious attackers will insert metal sheets into the booth to short-circuit the booth. Some nodes use metal hooks and AC 220 volts to burn out the main IC, and use a DC voltage power supply to burn out the electronic modules. Plus electrostatic high voltage. URE (such as gas ignition gas) is a master control IC method, such as breaking a trace of the instrument to achieve the purpose of stealing.
The above is what we have compiled for you about how to effectively prevent electricity theft with prepaid electricity meters. Through the sharing of this content, everyone has a certain understanding of how prepaid meters can effectively prevent electricity theft. If you want more in-depth understanding of how prepaid electricity meters can effectively prevent electricity theft market information.
