发明名称 DEVICE INSIDE OPERATION STATE MONITORING SYSTEM
摘要 <p><P>PROBLEM TO BE SOLVED: To allow a device inside monitor part to detect cutoff of a power supply in a unit and continue the operation state of monitoring an electronic circuit in the unit, when the power supply from a power voltage transducing circuit of the unit is cut off without providing a power cutoff detecting circuit in the unit. <P>SOLUTION: When there is a nonresponding unit monitoring means 6 in a poling operation performed to the respective unit inside monitoring means 6 in order for collecting monitoring results which are obtained by respective unit monitor means 6 of units 2a-2b by monitoring operations of unshown functional circuit of a function circuit part 5, the device inside monitoring means 8 detects that the unit inside power supply 16 supplied from the power voltage transducing circuit 4 is cut off, generates a unit inside monitoring standby power supply 13, which has the same voltage to the unit inside power supply 16, from a standby power supply 12 supplied from the power supply part 1 relative to a power voltage transducing circuit 7, and supplies unit inside monitoring standby power supplies 13a-13b relative to the nonresponding unit inside monitoring means 6. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p>
