<p>PURPOSE:To secure an easy power source diagnosis by comparing the output level of the computer with the set value, memorizing the comparison result in the form of the digital information and then transmitting the information memorized to the computer when the error occurs at the computer. CONSTITUTION:The output voltage of DC power sources I0-In of the electronic computer is supplied to A/D converter 10 via analog switch 6. Switch 6 is connected by switching to converter 10 while securing the synchronization with clock 8 under the control of controller 7. Controller 7 has an access to memory 9 into which the output voltage set value of power sources I0-I7 are stored, and the set value corresponding to the power source connected to converter 10 is supplied to comparator 11. Comparator 11 gives a comparison to the information given from memory 9 and converter 10, and then writes the result into memory 12 along with error information 13 of the computer. When some error is detected at the computer, the comparison result information within memory 12 and the error information are read out simultaneously under the control of controller 7 to be transmitted to the computer. Accordingly, an easy diagnosis becomes possible for the power source at the computer side.</p> |
