Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of shutdown energy test device, as shown in Figure 1, including force snesor 1, angular-rate sensor 2 and calculating mould
Block 3, the force snesor 1 and angular-rate sensor 2 are used to be mounted on acquisition door contact interrupter process on car door by the sucker of end
In applied force and angular speed.Wherein force snesor 1 is mounted on the lower section of car door outer surface door handle, angular-rate sensor
2 installations are in the same horizontal line close to the position of body hinge.The computing module 3 includes analog acquisition card 3.1, signal isolation
Amplifier 3.2 and runs software 3.3, the analog acquisition card 3.1 and 2 communication connection of force snesor 1 and angular-rate sensor,
Collected analog data is passed through again by being transferred in runs software 3.3 after 3.2 enhanced processing of signal isolation amplifier
The shutdown energy of integral operation calculating car door.
Preferably, which further includes the remote controler for starter operation, when tester is to force snesor 1
When applying active force, the operation of software systems on computing module 3 cannot be considered in terms of, so if wanting starter just needs two
People operates respectively, then solves this problem using the remote controler, emits light wave by infrared diode, light wave is computed
The infrared signal received is transformed into electric signal by the infrared receiver in module 3, and processor is decoded, and is demodulated corresponding
Instruction completes operation requirement to reach control equipment.
Further, detection system built in the runs software, the detection system for detect car door whether be closed completely with
