PURPOSE:To automatically stop the output of a microcomputer after deciding immediately occurrence of a trouble when no clock pulse is produced, by using an automatic recovering circuit to monitor the clock pulses produced from a microcomputer and producing a reset pulse when the computer has runaway so that the computer is automatically recovered. CONSTITUTION:The information received from each sensor of working parts of an agricultural machine are supplied to a microcomputer 1. A controller 5 containing an automatic recovering device 4 is connected to the computer 1 to monitor the clock pulse 2 sent from the computer 1. If the computer 1 has runaway and the output of the pulse 2 is cut, a reset pulse 3 is produced from the device 4 for automatic recovery of the computer 1. In this case, a trouble is decided if the computer 1 is not immediately recovered. Then the automatic control output is stopped and the trouble is displayed on an abnormality display device 7. At the same time, the state of the trouble is informed in voices through a voice recognizing device 8. |
