The device for detecting stand up action on cattle and the radio transmitting system for sending the detected standing signal to a computer were developed in 2001.1) Four mercury switch in the device were used for detecting standing action on cattle.2) The hind lower legs were suitable positions for attaching the device.3) The foals of detection were occurred when a cow scratched her head and while walking during which the devices were irregularly snaked.4) We developed the program in which the standing signal only after the succession of 10 minutes of lying position in cows should be accepted as a real standing action.The experiment of practical situation in which the cow was trained to move to the feeding station controlled by computer just after standing action were undertaken. The video recording was used to confirm the elimination spots in a pen.1) The single pen consisted of two parts were used. One part was a bed area where wood dust were applied and another was a feeding area where a feeding station was set.2) Five dry cows were used. The standing detection device were attached on the left hind leg of the animals.3) The one session were consisted of three period named preliminary periods, training periods, voluntary visiting periods.Results and discussion1) The rate of correct detection of standing up of cows was about 90%. This result was well acceptable for us.2) The results showed a trainability of cow to visit a feeding station just after standing.3) The reduction of elimination frequencies on beds were firmly expected using this system.4) The individuality of learning speed of cows were considerably varied. These results showed that the more effective training methods should developed in the future.

2001年研制了牛站立动作检测装置和将检测到的站立信号发送到计算机的无线电发射系统。1）装置中的四个水银开关用于检测牛的站立动作。2）后小腿是装置的合适位置。3）当奶牛抓头和行走时，发生检测马驹，在此期间，器械不规则地弯曲。4）我们开发了一个程序，其中只有在奶牛连续10分钟的躺卧姿势后，站立信号才应被接受为真实的站立动作。训练奶牛的实际情况实验在进行站立动作后，立即移动到由计算机控制的进料站。采用录像法确认注射笔内的消除斑点。1）使用由两部分组成的单支注射笔。一部分为铺木屑的床区，另一部分为设置饲喂站的饲喂区。2）5头干奶牛。3）一次试验分为预备期、训练期、自愿访视期3个阶段。结果与讨论1）奶牛站立试验的正确率在90%左右。结果表明：（1）奶牛在站立后可训练到饲喂站;（2）奶牛在床上的淘汰频率降低;（3）奶牛的学习速度个体差异很大。这些结果表明，更有效的训练方法，应在未来的发展。
