A voltage and current detection device connected with the microcontroller consists of a high current generator which is used for providing various-gear detection current to an ignition lock of an automobile to be detected, the microcontroller is connected with a photoelectric isolator, the photoelectric isolator is connected with a key plug-pull driving device and an asynchronous motor rotary driving device, the asynchronous motor rotary driving device is connected with a key spindle rotary device, the key spindle rotary device is connected with an angle encoder and a torque sensor, and signal output ends of the angle encoder and the torque sensor are connected with the microcontroller. The automobile ignition lock detecting system has the advantages that the system is fast and efficient in detection, automatically stores technical parameters of products, has friendly human-computer interface, and the like.

TW201012684 discloses a motorcycle having a multifunctional safety helmet, comprising a motorcycle, a safety helmet, and a key. The safety helmet comprises a snap ring, a sna ring checking circuit, a control system, an alcohol sensor, a temperature sensor, and a fan. The motorcycle comprises a latch circuit. The alcohol sensor senses alcohol concentration of a user after the' user wean; the safety helmet. The snap ring checking circuit senses whether or not the snap ring of the safety helmet is tightly clasped by the user; After passing the sensing detections of the alcohol concentration and the snap ring, the key is inserted to start the motorcycle. Otherwise, if the sensing detections of the alcohol concentration and the snap ring failed, the latch circuit would lock the inserting hole of the motorcycle, and an audio reminding signal is sent by an audio system of the control system. When the temperature sensor detects the temperature inside the safety helmet being too high, a message then is transmitted to actuate the fan for lowering the temperature. ·

These devices have been very useful in assisting people in providing safety while driving motorcycles and two wheelers. However, there is no system or method in the art which compels the driver to wear helmet before starting to drive the vehicle so that mishaps and injuries due to accidents can be minimized. There is hence, an unmet need of developing a system that is primarily designed to compel a driver to wear a helmet before he starts driving.
