摘要/Abstract

摘要： 为满足育肥猪获得正常生长所需采食量并达到精准饲喂控制等需求，以育肥猪为试验对象，设计一种育肥猪精准下料控制系统。研究通过使用双侧下料器，实现对称式双边下料，提高猪群的采食效率；增设触碰开关，猪只触动后执行预设料下料，避免饲料浪费；食槽内增设料位感应探针，猪只触碰感应开关时，若探针感应不到食槽内水料，系统自动补充水料到探针处，既保证猪只正常采食，又避免饲料浪费；增设防结拱装置，通过震动电机实现破拱，防止料粉受潮影响下料。试验结果表明，与理论采食量比较，智能饲喂方式下采食量低于理论采食量；饲喂采食量比例分别为10%，30%，30%，20%及10%时，获得较佳的采食量变化曲线。综上，所设计的双侧下料的育肥猪精准下料控制系统，采用拨轮下料的控制机构与嵌入式系统的协同工作，设备控制简单，下料稳定，计量准确，与进口设备比较，成本优势明显，适合在我国大、中、小型育肥猪场推广应用。

Abstract: In order to meet the requirements of feeding intake for normal growth and accurate feeding control of fattening pigs, a precise feeding control system was designed for fattening pigs. The research is to realize symmetrical bilateral feeding by using double side feeder to improve the efficiency of pig feeding; add touch switch, and then execute preset feeding after pig touch to avoid feed waste; add material level induction probe in the feed tank, and when the pig touches the induction switch, if the probe should not feel the water in the tank, the system will automatically replenish the water to the probe, which can ensure the pig to eat normally; add arch preventing device, and the arch breaking can be realized by vibration motor to prevent the material powder from being affected by moisture. The results show that: compared with theoretical feed intake, the intake of food in intelligent feeding mode is lower than that of theoretical feed; when the feed intake ratio is 10%, 30%, 30%, 20% and 10%, the better curve of the change of intake is obtained. In conclusion, the designed precision feeding control system of double side feeding pigs adopts the coordination work of the control mechanism of the wheel feeding and embedded system. The equipment control is simple, the feeding is stable and the measurement is accurate. Compared with the imported equipment, the cost advantage is obvious, which is suitable for the promotion and application in large, medium and smallsized fattening pig farms in China.
