Abstract

Currently, power grid sector is experiencing rapid development. The scale of the network is increasing and the degree of automation is being implemented. With these changes, the requirements for switching, testing equipment, and troubleshooting electrical equipment are increasing. A traditional tamper-proof system that uses computer keys has a number of limitations. For example, it does not provide sufficient mobility, after which the operators must be within range of the computer. In addition, this system may be vulnerable to attacks. This article proposes a new generation of five online microcomputer anti-blocking systems based on NFC (Near Field Communication) technology. This system has a number of advantages compared to the traditional system: mobility allows them to work in any place where there is access to the network, informativeness allows them to make a more informed decision, intelligence to completely prevent accidents, safety allows to prevent false activation of equipment. This project applies the smart phone client to the anti-missing lock function of the power grid, develops the mobile phone client on the Qt on Android platform, builds and perfects the eight functions of the mobile terminal five-proof system, and applies the NFC technology to unlock the mobile phone front end. The skill of the client and the mobile phone are skillfully combined to solve the problem that the data communication between the personnel and the background is difficult. A new NFC-based tamper-proof system is a promising solution that has the potential to revolutionize the power grid industry. This system has several advantages over the traditional system and can help operators make switching operations safer, more efficient and more economical.
