Embodiment 1
[0043] Such as figure 1 Shown, a kind of automobile impact signal detection method, its steps are as follows:
[0044] Step 100 The acceleration sensor collects the acceleration signals of the car in the horizontal front-back direction, the horizontal left-right direction, and the direction perpendicular to the horizontal plane. The single-chip microcomputer collects the data from the acceleration sensor and processes the data. The acceleration sensor and the single-chip microcomputer are integrated in the same printing In the circuit board (PCB, Printed Circuit Board), it is installed on the top of the inner side of the car and communicated with the monitoring module. The horizontal front and rear directions of the acceleration sensor are parallel to the windows on both sides of the car; the single-chip microcomputer reads the acceleration in the acceleration sensor through the SPI bus Data signal; after parking, the impact signal detection system is automatically activated t...
Embodiment 2
[0062] A car shock signal detection device is characterized in that it includes an acceleration sensor and a single-chip microcomputer, and the acceleration signals collected by the acceleration sensor in the three directions of the horizontal front-back direction, the horizontal left-right direction, and the direction perpendicular to the horizontal plane are used as the acceleration signals in three directions , characterized in that it includes a reading module, a noise reduction module, a combination processing module, a storage module, a first calculation module, a first comparison module, a second calculation module, a second comparison module and a monitoring module.
[0063] After parking, the impact signal detection system is automatically started to detect the impact signal. The reading module reads the acceleration signals in the x, y, and z directions collected by the acceleration sensor. Represents the acceleration signal value in the horizontal left and right dire...
