英文摘要:
Due to the issues of low throughput and low time synchronization accuracy when traditional power timing terminals transmit communication data, a power timing terminal for novel power system communication network security based on MQTT (message queuing telemetry transport) protocol is studied. In the hardware design of the power timing terminal, this method includes a time keeping module, a dual-mode satellite navigation receiving module, an application interface module, a display module, and a main control module. In the software design of the power timing terminal, the discrete domain sampling data model is introduced into the software design, and on this basis, the equivalent circuit of the DC/ DC converter is designed. The signal is collected using this circuit, and the collected signal is converted into data to complete data collection. The data transmission of the power timing terminal is completed through the MQTT protocol, and the design of the power timing terminal is completed by combining hardware and software design. The experimental results show that the proposed method has high time synchronization accuracy, high throughput, and low communication data transmission delay.
