Embodiment 1

[0023] see figure 1 ~ Image 6 , a detection and protection system for preventing false starts of electric vehicles, including a pressure sensor 1 installed at the saddle position of the electric vehicle to detect the pressure of the saddle, the pressure sensor 1 is connected to a signal conversion circuit 2, and the signal conversion circuit 2 is connected to a single-chip microcomputer control Circuit 3, the single-chip microcomputer control circuit 3 is connected to the relay drive circuit 4; the signal of the pressure sensor 1 passes through the signal conversion circuit 2, and then enters the single-chip microcomputer control circuit 3, and the single-chip microcomputer control circuit 3 drives the relay according to the set logic to control the starting circuit of the electric vehicle On and off; the power supply circuit 5 supplies power to each circuit of the system.

Embodiment 2

[0025] This embodiment is basically the same as Embodiment 1, and the special features are as follows: the specification model of the silicon pressure sensor is PX138-0.3D5V, the excitation voltage is DC 8V, and the storage temperature is -40~125°C. The pressure sensor can provide differential pressure, gauge pressure or absolute pressure measurement, has a precision 5V output range, accurate temperature compensation and constant excitation voltage.

[0026] The signal conversion circuit Such as figure 2 , the pressure sensor (1) is connected in series with a fifth resistor R5, and then connected to the second operational amplifier Q2A, pin 2 is directly connected to pin 1, and a sixth resistor R6 and the first A parallel structure composed of twelve capacitors C12 is then converted to an output signal.

[0027] The system control board adopts the slot P2 with 3 ports as the interface to receive the signal from the sensor, and the three ports of the slot are the positive t...

Abstract

The invention relates to a detection protection system preventing mis-starting of an electric bicycle. The detection protection system comprises a pressure sensor which is mounted at the position of a saddle of the electric bicycle and used for detecting the pressure of the saddle, the pressure sensor is connected with a signal conversion circuit, the signal conversion circuit is connected with a single-chip microcomputer control circuit, and the single-chip microcomputer control circuit is connected with a relay drive circuit. Signals of the pressure sensor pass through the signal conversion circuit and then enter the single-chip microcomputer control circuit, and the single-chip microcomputer control circuit drives a relay according to set logic to control on and off of a starting circuit of the electric bicycle. A power supply circuit supplies power to all circuits of the system. The detection protection system preventing mis-starting of the electric bicycle provides starting safety protection for each electric bicycle.

Description

technical field [0001] The invention relates to the field of signal detection, in particular to a detection and protection system for preventing electric vehicles from starting by mistake. Background technique [0002] An electric vehicle is a vehicle that uses a battery as an energy source, and converts electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed. With the growth of the consumer group of electric vehicles, it also brings a series of safety problems. The starting method of the electric scooter is simple, you only need to turn the speed handle after twisting the switch, and you can ride. But it is precisely because of this simple startup method that in some cases, some security risks will be formed. For example, when buying vegetables in the vegetable market, it is not uncommon for children to be injured due to misuse of the electric car key by parents forgetting to unplug it. [0003...
