Design of Vehicle Terminal for Train Monitoring and Alarming Based on GSM/GPS
This thesis reasonably designs the hardware of the urban railway train monitoring alarm vehicle terminal,based on the hardware and software micro-structure of the C8051F340 microcontroller processor and requirements of the actual urban railway train monitoring alarm vehicle terminal system,analyzes the current running train's position,speed,running direction and other related information which are from the GPS module,communicates data using GSM module.Software is part of the modular design,it chooses C programming language,in order to avoid traffic congestion,ensures the reliability of data transmission,GPS module receives data through the serial port interrupt,GPS receiver module achieves the current train's running position,speed,run direction information,GSM module also uses the serial port interrupt to send data,transmits the information safely and reliably to the monitoring center.
