| 摘要 |
The sensor signal measuring device has an A/D converter (ADC), incorporated in a micro-controller, receiving analogue signals (Vmess) from at least one sensor or sensor set (SS1,SS2), with a voltage regulator providing a supply voltage (V5int) for the micro-controller and an independent reference voltage (V5a,V5b) for each senor or sensor set. A pair of monitoring circuits (UW1,UW2) provide respective reset signals for the micro-controller when respective independent reference voltages (Ref1,Ref3) obtained from the operating voltage are outside their acceptable ranges.
