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.
