项目摘要

The Ministry of Internal Affairs and Communications assigned radio waves to wireless systems that to track the behavior of animals in 2008. So we developed a grazing cow real-time monitoring device using the radio band, and verified its performance. Three Holstein cows were used for surveys. The GPS receiver and the VHF transmitter for real-time monitoring put on each cow. The data obtained via the receiving station was set to indicate the position coordinates in real time on the Web.Positioning error of positioning coordinates by the GPS receiver and the real-time monitoring device was 94.1m. The maximum and the minimum error were 745.2m and 2.4m, respectively. Positioning error depends on behaviours of cows. The error came to have a shorter at rest (72m) than at moving (80m) and grazing (147m), significantly(P<0.05).

2008年，日本总务省将无线电波分配给无线系统，以跟踪动物的行为。为此，我们研制了一种利用无线电频段的放牧奶牛实时监测装置，并对其性能进行了验证。三头荷斯坦奶牛用于调查。每头奶牛都配有GPS接收机和VHF发射机，用于实时监测。通过接收站获取的数据在Web上设置真实的表示位置坐标，GPS接收机和实时监控装置的定位坐标定位误差为94.1 m。最大误差为745.2m，最小误差为2.4m。定位误差取决于奶牛的行为。静止时的误差（72m）显著小于移动时的误差（80m）和放牧时的误差（147m）（P<0.05）。
