ReceiveRFID()；ReceiveRFID();
信号处理单元判断牲畜是否正常活动的指令：Instructions for the signal processing unit to judge whether the livestock is moving normally:
Compare()；compare();
信号处理单元向输出单元发送异常报警信号的指令：Instructions for the signal processing unit to send an abnormal alarm signal to the output unit:
SendAlert()；SendAlert();
本发明的系统和装置采用在牲畜上佩戴牲畜传感器来监测牲畜是否活动以及是否在限定范围内来防止盗窃的技术，具有成本低廉、简单方便等特点，更适用于养殖行业进行活体牲畜的养殖管理等。牲畜传感器的防盗范围由无线射频模块的通讯距离决定，并可在有效范围内，通过软件进行距离设置。处理器在以下几种情况发出报警信号：在用户自定义的一段时间内，没有收到牲畜传感器发回的信息；牲畜传感器发回的信息中，运动量无变化。The system and device of the present invention adopt the technology of wearing livestock sensors on livestock to monitor whether the livestock is active and whether it is within a limited range to prevent theft. It has the characteristics of low cost, simplicity and convenience, and is more suitable for the breeding management of live livestock in the breeding industry wait. The anti-theft range of the livestock sensor is determined by the communication distance of the radio frequency module, and within the effective range, the distance can be set through software. The processor sends out an alarm signal in the following situations: within a period of time defined by the user, no information sent back from the livestock sensor is received; in the information sent back by the livestock sensor, there is no change in the amount of movement.
