放牧家畜质量自动称量系统的设计与试验

Design and experiment of livestock auto weighing system

为解决放牧家畜在称质量过程中存在的费时、费力、精度差以及较危险等问题,利用RFID技术,通过自主开发的计算机程序,将家畜电子耳标、阅读器与电子秤有机结合,实现放牧家畜自动称质量功能。试验结果表明,与以往普通台秤或电子秤相比,这种新型的自动称质量系统可减少称质量时间70%以上,节省劳动力50%以上,同时避免称家畜质量时人员发生危险和对家畜造成的伤害。利用放牧家畜自动称质量系统可实现对家畜个体体重和体况等的有效监测。

In order to save time and labor and reduce risk of injury to the livestock or to the people while measuring changes in the body weight monitoring of grazing livestock, a new livestock weighing system was invented and evaluated in this paper, which involved an E-tag fitting to each animal, and using a RFID reader, an electrical scale and special sotiware. The result showed that the new livestock weighing system can save more than 70 percent of labor and 50 percent of the weighing time compared to the traditional way, and avoid the dangers associated with handling large livestock. By using of the E-tag based on the RFID technology, the monitoring of body weight and body condition for individual livestock is now possible.
