Embodiment Construction
[0027] The alarm (1) equipped with a three-dimensional acceleration sensor and a single-chip microcomputer can measure the acceleration values in the X, Y, and Z axes. The alarm may be installed under the rear seat (3) or under the pedal (4) of the electric bicycle (2), Installed in the horizontal direction, the acceleration values of the three axial directions of the electric vehicle (2) can be measured in real time.
[0028] According to the measured acceleration value, the data processing method described above can be used for real-time detection and alarm for accidents that occur during the operation of the electric vehicle.

The invention relates to a data processing method of an acceleration sensor in an automatic accident alarm device for an electric bicycle. According to the method, whether an accident occurs on the electric bicycle or not and accident occurrence relevant circumstances and severity degree can be accurately determined in real time through a single chip microcomputer by means of output data of the three-dimensional acceleration sensor in an electric bicycle burglary prevention alarm.
Description
Technical field [0001] The patent of the present invention relates to an accident judging method based on acceleration sensor data processing in an automatic alarm device used in electric bicycles. Through this method, the output data of the acceleration sensor can be used to accurately judge whether there is an accident in the electric bicycle in real time, and whether the accident occurred. The circumstances and severity of the occurrence. Background technique [0002] Currently, electric bicycles are widely used due to their low cost, environmental protection, and convenience. And various alarms and anti-theft products based on electric bicycles are many. Among them, the ones that are widely used mainly include: anti-theft alarm devices based on GSM network and GPS positioning device. Most of these devices have built-in acceleration sensors, which are used as vibration and motion sensors for electric bicycles, and are used to monitor abnormal vibration and movement of e...
