Title: Multiplex control device
Inventor: AMAHI YASUHIRO
IPC: G05B23/02
Filed: 1979-12-14
Abstract: PURPOSE:To increase the detection accuracy of trouble with a simple constitution, by installing the double-system control device with which the same operation is performed with the selected output at one side delivered to the process plus the diagnosis control device which has the same function as the double-system control and is used only for detection of a faulty device. CONSTITUTION:The A-system control device 10 and the B-system control device 20 fetch the process signal Si and deliver the control signal So after carrying out the prescribed operation. The signal So is usually delivered from either one of said two systems. The operation output during a sampling plus the intermediate data are sent to the diagnosis system control device 40 from both systems to give a check whether the difference of the operation results is within a prescribed range or not. If the difference is out of the prescribed range, the same operation is carried out based on the process signals Si fetched at a time. Thus the faulty system is detected by the majority logic. With this output of detection, the swtiching logic 31 switches the selected system to another if it has some trouble.
