Problem to be solved: to provide a system capable of quickly grasping the cause of the failure by grasping the state in the feed piping in real time.Feed hopper and feedFeed feed hopper feeds feedFeed pipe 12 to feed the supplied feedDisposed in the feed pipeThe transporting long member 14 for feeding the feed within the feed pipeOne or more proximity sensors 40 provided at one or more of the outer wall surfaces of feed pipingA computer which receives the detection data of the feed state of the feed in the feed pipe detected by the proximity sensor 40 and the state of the carrier long member 14AndComputer control unitAn abnormality in the feed pipe 12 is determined based on the feed state of the feed received from the proximity sensor 40 and the detection data of the state of the conveying long member 14.Diagram【課題】飼料配管内の状態をリアルタイムで把握して故障の原因をいち早く察知できるシステムを提供する。【解決手段】飼料供給ホッパーと、飼料供給ホッパーから飼料が供給され、供給された飼料を搬送する飼料配管12と、飼料配管12内に配置され、飼料配管内で飼料を搬送するための搬送用長尺部材14と、飼料配管12の外壁面の1又は複数個所に設けられた1又は複数の近接センサ40と、近接センサ40によって検出された飼料配管内の飼料の搬送状態及び搬送用長尺部材14の状態の検出データを受信するコンピュータと、を有し、コンピュータの制御部は、近接センサ40から受信した飼料の搬送状態及び搬送用長尺部材14の状態の検出データに基づいて飼料配管12内の異常を判断する。【選択図】図4
