Abstract:

In view of the shortcomings of the existing technology, an intelligent security lockout system based on RFID technology is designed. This system integrates RFID technology, Internet of Things technology, artificial intelligence technology, and automation control technology to achieve the intelligentization and automation of the security lockout system jobs. In this design, a security lockout system including a device layer, a lockout hardware layer, a lockout working layer, and a management layer was constructed, and a communication module supporting the IEC 61850 communication protocol was used for data communication, so that the upper management center could directly obtain the underlying RFID device information. The system also designs RFID smart locks including tags, readers, and data management systems. The nRF905 radio frequency transceiver chip is used to receive and transmit security fault data. The lockout control circuit with D triggers is used to receive fault signals. It also controls the PWM pulse operation and executes the blocking operation. Experiments show that the method studied in this paper has short response time, fast calculation speed, high accuracy and good stability.
