  • Detection circuit and system for detecting detector removal failure
    Patent number: 12488676
    Abstract: The present application relates to a detection circuit for detecting a detector removal fault. The detection circuit comprises: a switching circuit. The switching circuit comprises one or more switching elements; an energy storage element; and a control circuit for controlling the energy storage element to discharge by controlling the one or more switching elements to perform an opening or closing action. The control circuit is configured to cause the energy storage element to discharge based on a first loop if the detector is removed from the diode bases, and to cause the energy storage element to discharge based on the first loop and a second loop including the terminal resistor if the detector is not removed from the diode bases. The control circuit is further configured to detect the detector removal fault based on an output voltage of the area monitoring module during discharge process.
