手動啟停(ting)也好，其(qi)本質是不(bu)同的(de)來(lai)源的(de)啟停(ting)指令，其(qi)程序作(zuo)用是一(yi)樣的(de)，但(dan)樓主卻(que)使用了兩種邏(luo)(luo)輯(ji)來(lai)做同一(yi)件事情，這是簡單邏(luo)(luo)輯(ji)還(huan)好做，但(dan)是復雜邏(luo)(luo)輯(ji)控制要實(shi)現就顯得雜亂(luan)了。既然有START FAILED，那也會有STOP FAILED。出錯(cuo)判(pan)斷時間，調節不(bu)靈活，不(bu)如直接用定時器(qi)，但(dan)卻(que)是個FC。電(dian)機的(de)狀態(tai)邏(luo)(luo)輯(ji)也是不(bu)甚合理。
