Voltage signal or current signal, the plug from falling sensor senses plug and comes off from interface, plug from falling detector unit
It is normal operation to judge that the plug comes off from interface, therefore will not stop the power supply to the interface, and such operator is pulling out
After lower handle plug, can at once plug an other handle and be operated, and not affect power supply of the HPI to handle.When
Operator be not turned off bat-handle switch, when not cutting off handle power supply, plug from falling detector unit there is no bat-handle switch pass
Signal is closed, the plug from falling sensor senses plug and comes off from interface, plug from falling detector unit judges the plug from connecing
It is improper operation that mouth comes off, therefore stops the power supply to the interface, prevents unexpected generation.
In other implementations, plug from falling detector unit can by other means judge that the plug is de- from interface
It is normal operation to fall.For example, also there is pressure sensor, when operator normally plugs handle plug, behaviour on the plug
The hand of author can give the certain chucking power of the plug or grip pressure power, and the pressure sensor believes the pressure state for detecting
Number plug from falling detector unit is passed to, so as to judge that coming off for plug is the normal operation behavior of operator, otherwise judge to insert
Head come off for abnormal operation.And for example, infrared sensor is there is also mounted near the interface, when operator normally plugs handle
During plug, infrared sensor can experience the position of operator's hand, so as to judge that coming off for plug is that operator normally grasps
Make behavior, otherwise judge coming off for abnormal operation for plug.And for example, acceleration transducer is also equipped with the plug, by
In plug is improper come off when, the plug can be subject to many acceleration bigger than normal operating, therefore from acceleration transducer
Measured value may determine that whether coming off for plug is the normal operation behavior of operator.
