Abstract
A dual-sensor signal collecting circuit comprises circuit (11), a second sensor signal collecting circuits, an AD sampling circuit, an AND gate determination circuit and a collected signal averaging circuit. Output ends of the sensor signal collecting circuits are connected to respective input ends of the AND gate determination circuit, respective input ends of the collected signal averaging circuit and a first AD sampling port of the AD sampling circuit; an output end of the AND gate determination circuit is connected to a power supply end of the collected signal averaging circuit; an output end of the collected signal averaging circuit is connected to the first AD sampling port of the AD sampling circuit. When the sensors operate normally, the collected signal averaging circuit outputs an average sampling value to the first AD sampling port, when one is damaged, a sampling value of the one operating normally is output to the first AD sampling port.
