Design of Electronic Seal Terminal for Tank Vehicles

Abstract

Based on ARM Cortex-M3 processor LM3S2948 as the core of the vehicle terminal and used enhanced 8051 MCU STC12C5A60S2 as the core of the control board of the electronic seal, an electronic seal terminal for tank vehicles is designed. Combined the control board with the vehicle terminal to achieve the tank vehicles ports’ open and close, the communication between control board and vehicle terminal accomplish the control of ports, the 3G network communication between vehicle terminal and the central server accomplish the data’s up and down. This paper, began with the hardware design of electronic seal terminal, put forward the flow chart of the software design of electronic seal terminal, as well as the communication protocol between vehicle terminal and control board and the communication protocol between vehicle terminal and central server.
