Abstract:Aiming at the problem that the police dog attendance and the daily training management can not grasp the state of the police dog in real time, the monitoring node hardware system with ATxmega32E5 as the master is designed. The system includes the Beidou positioning module, the acceleration monitoring module, the heart rate acquisition module, the wireless communication module , And set up based on LabWindows / CVI set of monitoring, configuration, storage and map matching function of the host computer terminal. The monitoring node hardware system has the characteristics of miniaturization, wearability and embedding. In the actual management of the police dog, it can observe the acceleration module data and the data of the heart rate monitoring module through the host computer terminal, and master the fatigue and health status of the police dog. It is proved that the system is reliable and effective, and it can realize the accurate, real - time positioning, speed, acceleration and heart rate monitoring of the police dog, which can effectively solve the problem of real - time monitoring of police dogs.
