Car one-key start-stop key controlled by APP Wechat and based on Beidou communication

The invention discloses a car one-key start-stop key controlled by APP Wechat and based on Beidou communication. A control module is arranged on a Wechat official account on a mobile phone, the startof a car can be remotely controlled, the start key is pressed, Wechat sends a signal to a PCB which is always connected to the Internet and is powered by a rechargeable battery, and the PCB receives the start signal. A main control chip on the PCB controls a relay to close a switch of an electromagnetic coil, the electromagnetic coil generates a magnetic field, a main rod body inside the PCB is pushed outwards by a magnetic block, the end of the main rod body is in contact with contact terminals at both ends of a resistor R1, protruding elastic pieces on a second rod body at the back of the main rod body move to an electrode column, and the electrode column is pressed down. After the electrode column is pressed, the electrode column recedes to a plunger and is in contact with electrodes onthe plunger. The electrod
