MUTUAL MONITORING METHOD BETWEEN COMPOSITE ELECTRONIC COMPUTER

PURPOSE:To improve the contact between electronic computers by monitoring the working states of both electronic computers with each other in a composite electronic computer system. CONSTITUTION:A master electronic computer contains a monitor program for a slave electronic computer to monitor the working state of the slave electronic computer. While the slave electronic computer contains a monitor program for a master electronic computer to monitor the working state of the master computer. If the monitor program for the slave computer detects the abnormality, an abnormal state detection message to the master electronic computer. If the monitor program for the master computer, the slave computer is suddenly stopped. Thus the abnormalities can be mutually processed in a composite electronic computer system.
