OPERATIONAL CONTROLLER OF HYDRAULIC FARM WORKING MACHINERY

摘要

PURPOSE: To improve the extent of reliability in view of operations by detecting any operational failure in an automatic stopping mechanism and giving notice to an operator of it. ;CONSTITUTION: An operating state comparing means H judges that an actual operating state has exceeded the allowable operating state on the basis of an allowable operating state signal of farm working machinery A to be outputted out of an allowable operating state outputting means E and an actual operating state signal of the machinery A to be outputted out of a farm working machinery operating state detecting means F, thereby outputting an operating state excess signal. Likewise, a stop judging means I outputs a stop judging signal of a hydraulic actuator B on the basis of this operating state excess signal and an operating direction signal out of an operating direction detecting means D, and a stop signal outputting means J outputs a stop signal to an operation stopping means G. On the other hand, an operational failure judging means L receives the stop signal and an operating state signal out of an operating state detecting means K and in the case where the operating state signal is a signal other than the signal conformed to a stop state of the hydraulic actuator B, it outputs an operational failure signal, thereby starting an alarm generating means M.;COPYRIGHT: (C)1995,JPO
