The invention relates to a self-locking system of an electric bicycle. The self-locking system comprises a single-chip microcomputer, an analog-to-digital converter, an alcohol detector, a stepping motor, a power module and an alcohol sampling system which are installed on the electric bicycle. The alcohol detector is arranged in the alcohol sampling system and connected with the single-chip microcomputer through the analog-digital converter, the single-chip microcomputer is in control connection with the stepping motor, the power module is electrically connected with the single-chip microcomputer and the stepping motor, and the stepping motor is used for driving wheels of the electric bicycle to rotate. A gas-sensitive alcohol detector is adopted, and when it is detected that the alcohol content in exhaled air of a driver exceeds the standard, a circuit is cut off and cannot operate. The self-locking system is in a non-locking state in a normal state, is locked immediately once alcohol is detected to exceed the standard, and returns to the normal state when the alcohol content is lower than a threshold value. Therefore, potential safety hazards caused by drunk driving of the electric bicycle are avoided, the driving safety is improved, and the system has a good application prospect due to the humanized design and excellent safety performance.

    本发明涉及一种电动自行车自锁系统,包括安装在电动自行车上的单片机、模数转换器、酒精探测器、步进电机、电源模块以及酒精采样系统。酒精探测器设置在酒精采样系统中,酒精探测器通过模数转换器与单片机连接,单片机与步进电机控制连接,电源模块分别与单片机以及步进电机电性连接,步进电机用于驱动电动自行车的车轮转动。采用气敏酒精探测器,在检测到驾驶员呼气中酒精含量超标时,切断电路使之无法运转。该自锁系统在正常状态下为非锁定状态,一旦检测酒精超标,立刻锁定,当酒精含量低于阀值,又恢复正常状态。从而避免了酒后驾驶电动自行车带来的安全隐患,提高了驾驶的安全性,人性化的设计和出色的安全效能使得系统具有良好的应用前景。
