A design of embedded system which aims at the application of track measurer is described. The mathematics model of orientation、 gauge, horizontal, height and mileage are put forward. The system is mainly made of Sensor, A/D Converter, ARM7 Microcontroller LPC2148 and PC Computer. the memory capacity can save more than 100kin line inspection data. With emphasis on Data Acquisition System, the mean filter method is also discussed. Compared with manual measurement, the instrument has advantages of high precision, automatical measurement and displayed in real time. According to the analysis of the software, the measurer reaches the request of design. It can be used in ballastless track construction and adjust the built line.
