Advantages Of STS Code Type Prepaid Energy Meter in Application

STS code-type prepaid electric energy meter refers to a prepaid electric energy meter that conforms to the STS standard (IEC62055 international standard) and uses a 20-digit code as the transmission medium for electricity purchase information. The STS standard is currently the only open prepaid system standard in the world. The application of this technology needs to be authorized by the STS Association, which ensures the safety of the power company when applying the STS system.

The conventional prepaid electric energy meter mainly refers to the IC card type electric energy meter, including contact type and non-contact type; its working principle is that the power supply department uses the electricity sales system to encrypt the purchased electricity and write it into the user's IC card, and then use The user recharges the electricity to the electric energy meter through the IC card, thereby realizing the transfer of the user's electricity purchase information. At present, IC card energy meters mainly have the following shortcomings:

Compatibility issues: Different IC cards use different encryption methods, and different suppliers use different ICs, which are difficult to be compatible with and have poor scalability.

Difficulty in purchasing electricity: Customers must purchase electricity at the designated business point of the power company, and the electricity purchase method is single.

Security issue: The power is stored on the card through encryption, which is easy to be damaged, lost or attacked.

Each meter needs to use an IC card, which is costly and inconvenient to use.

Compared with the traditional IC card electric energy meter, the STS electric energy meter has the advantages of convenient operation, diverse transmission media, convenient transmission, high security and compatibility with international standards. Electricity can be purchased in various ways such as SMS, online banking, and electricity sales points. And the third-party-STS protocol and key are used to encrypt the electricity meter one-to-one, so that the user information is separated from the electricity purchase information, which is more secure and reliable.
