Specifically, as shown in fig. 3 to 5, the main control board for realizing the steering function is an Arduino development board 14, which is installed in the slot 11 at the side opposite to the Maxibit development board 13, and the steering display device is a dot matrix screen 18. The Arduino development board 14 is integrated with a MEMS accelerometer, through which acceleration change information of the electric bicycle in the vertical axis direction can be calculated to determine steering information of the electric bicycle. If the increment value of the MEMS accelerometer on the Y axis is calculated, the electric bicycle is indicated to turn in one direction when the increment value is positive, and the surface turns in the other direction when the increment value is negative. In this embodiment, when the increment value is detected to be greater than or equal to 300 during the running of the electric bicycle, the electric bicycle is indicated to turn right, and at this time, a right arrow is displayed on the dot matrix screen 18; when the increment value is detected to be smaller than-300, the electric bicycle is indicated to turn left, and a left arrow is displayed on the dot matrix screen 18. The steering information of the electric bicycle can be clearly known by the following vehicles.

Considering that the performance of the development board is limited, most of the processing power of the development board is consumed when video recording is performed. Therefore, the utility model adopts two development boards (Maxibit development board 13 and Arduino development board 14) to respectively realize different functions and improve the processing efficiency.

It should be noted that other development boards may be used instead of the Maxibit development board 13 and the Arduino development board 14, and a gyroscope may be used instead of the MEMS accelerometer to obtain the direction change information to realize the function of steering detection.

As shown in fig. 1 or 6, the apparatus for realizing the overspeed detection and reminding functions includes a speed detection device and a voice device. A speed detecting device is installed at the top end of the housing 10 for obtaining the running speed of the electric bicycle.

The GPS speed sensor 17 is connected with a satellite to acquire position information in real time, and calculates the speed of the electric bicycle according to the position information at different moments. The GPS speed sensor 17 is widely used in automobiles, and will not be described here.

The Arduino development board 14 calculates the speed of the electric bicycle according to the data of the GPS speed sensor 17, and determines whether the electric bicycle is overspeed, and if overspeed, sends a play voice signal to the speaker 15 to play a prompt sound. For example: when it is detected that the speed of the electric bicycle exceeds 13km/h, the horn 15 plays "please decelerate".

When the electric bicycle turns, the horn 15 can also play the turning voice, for example: when the electric bicycle turns left, the horn 15 plays "turn left, please note".

It should be noted that the GPS speed sensor 17 may be replaced by another device capable of measuring speed.

In one example, the Arduino development board 14 and the mobile terminal are also formed as a set of blinkers (an internet of things solution), and then the mobile terminal can view the electric bicycle speed data and steering data obtained on the Arduino development board 14.
