为了提高我国母猪养殖设备自动化和智能化水平，设计一种由全机械式饲喂通道、精准饲喂器及智能控制器组成的群养母猪智能化精准饲喂装置,该装置采用少量多次的下料方式,以可编程控制器(PLC)作为核心控制器，实现母猪采食信息的采集与储存。性能测定分析显示，当单次下料量为100 g时，该装置的日下料量平均相对误差为2.59%，变异系数的均值为2.25%，最远识别半径为16 cm。研究结果表明，该装置具有准确识别进食母猪身份、隔离饲喂及精准下料等功能，装置的下料精度和稳定性以及识别范围均达到设计要求。
In order to improve the automation and intelligence level of sows breeding equipment in China,an intelligent and precise feeding equipment for groupbreeding sows is designed,which consists of all mechanical feeding channels,precision feeders and intelligent controllers. The device adopts a small number of feeding ways and a programmable controller as the core controller to collect and store the feeding information of sows. The performance measurement analysis showed that when the single discharge amount was 100 g,the average relative error of the daily discharge amount of the device was 2.59%,the mean coefficient of variation was 2.25%,and the maximum identification radius was 16 cm. The results show that the device has the functions of identifying feeding sows accurately,isolating feeding and precise feeding. The accuracy and stability of feeding and recognition range of the device meet the design requirements.
