The invention discloses an electric vehicle alarm method and device and a storage medium, and the method comprises the steps: detecting a continuous voltage waveform signal generated by a vibration switch in an electric vehicle when an electric vehicle instrument shakes; determining waveform data in each period according to the continuous voltage waveform signal; according to the waveform data, all durations of the low level in a plurality of periods are calculated and obtained; the total cycle time is calculated, and according to all the duration time of the low level and the total cycle time, the low level time proportion in the total cycle time is calculated; and comparing the low-level time proportion with a preset threshold value, and when the low-level time proportion is higher than the preset threshold value, judging that the current shake meets an alarm condition, and generating alarm information. According to the invention, the low-level time ratio in the preset period is calculated based on the continuous voltage waveform signal, and the low-level time ratio is compared with the preset threshold value to judge whether to give an alarm, so that the alarm accuracy of the electric vehicle can be effectively improved.

    本发明公开了一种电动车报警方法、装置及存储介质,其中方法包括:在电动车仪表发生晃动时,检测电动车内部振动开关产生的连续电压波形信号;根据连续电压波形信号,确定每一个周期内的波形数据;根据波形数据计算得到若干个周期内低电平的所有持续时间;计算总周期时间,根据低电平的所有持续时间和总周期时间,计算得到在总周期时间内的低电平时间占比;将低电平时间占比与预设阈值进行比对,在低电平时间占比高于预设阈值时,判断当前晃动满足报警条件,并生成警报信息。本发明并基于连续电压波形信号计算得到预设周期内的低电平时间占比,通过将低电平时间占比与预设阈值进行比对以判断是否发起警报,能够有效提高电动车报警的准确性。
