Data Collecting And Monitoring System's Structure And Hardware Development Based On GPS

With the rapid development of the computer and positioning technology, a great number of manufacture develop their products for mobile positioning. All of these give us more convenience during travel and improve the traffic management. This paper proposed a mobile positioning system made for low-end users. This system features in low cost and high stability.This system consists of mobile positioning terminal and mornitor center all of which include software and hardware implementations. My job mainly includes: system structure proposal; hardware products selection; GPS receiver peripheral circuit and main controller module circuit design; data collection software design and implementation.This system is based on GPS technique, which can offer round-the-clock positioning function; a 2051 processor is used to expand serial interface in main controller module, so that the main processor can respond to the GPS module and GPRS/SMS module simultaneously; the communication manner between mobile terminal and mornitor center include: SMS messages and GPRS.This system is suitable for low-end users because the cost was carefeully considered when we were selecting hardware products and technique. And its function can be expanded easily by software update.
