Personnel And Vehicles. Ground Motion Sensor Detection System

The moving target' s seismic signal can be acquired by a single-axis seismometer. As to the software, it realized feature extraction and target identification from the seismic signals of representative moving targets using the zero-crossing method in time domain. Then this paper creates a pertinency arithmetic depend on seismic signal to locates the moving target.In the hardware design of the system, the system' s circuits are presented in detail. The system includes the signal conditioning circuit, the data acquisition circuit, the serial communication circuit, the power circuit and so on. Also the points that we should pay attention to are given.In the software design of the system, the methods of the design are given in detail, we introduce serial communication and program serial communication software and the computer' s graphic user interface design are also introduced.This paper' s whole design is built on the unattended ground sensor (UGS) system. The system make use of wire communication and the computer can receive the identifying result in 1000 meters depend on the wire communication system. The system can alarm person intrusion and vehicle intrusion, and can distinguish person from vehicle.
