Alarm, or a beep sound alarm. The mercury switch K2 is mounted at the rear end of the bracket cover 9, perpendicular to the center line of the bracket cover 9, and inclined at a position of 30 to 45 degrees from the horizontal plane.

When taxiing, first charge the power supply E1 through the charging interface. After the charging is completed, the main switch is turned on to supply power to the main control board 6, and the main control board 6 starts to work. The first pressure sensor S1 and the second pressure sensor S2 respectively mounted on the bracket cover 9 collect the human body pressure information, transmit it to the main control board 6 for processing, and then send a control signal to the driving motor D, so that the driving motor D drives the pulley 2 Rotate to achieve forward, backward, acceleration, deceleration, stop and other actions. In the power-off mode, the corresponding power indicator light 10 is on, and the main control board 6 sends a signal to control the pulley 2 to move forward. When the power source E1 needs to be charged, the main control board 6 sends a signal to control the driving motor D to start the charging mode, and the driving motor works in the power generation mode, and the current generated by the motor is rectified by the rectifier, and then converted into a set voltage by the voltage conversion module to be a power source.

The comparator determines the human body pressure information collected by the first pressure sensor S1 and the second pressure sensor S2. When the signal of the first pressure sensor S1 is greater than the signal collected by the second pressure sensor S2, the corresponding body leans forward. It is the mark position of the forward slide, and it needs to be accelerated. At this time, the output of the comparator is a positive potential, and the signal is processed by the main control core board to issue a command to drive the motor to work, and the skater advances; if the signal of the first pressure sensor S1 When the signal is smaller than the signal collected by the second pressure sensor S2, the corresponding body is backward tilting, which is the position of the flag that slides backward or stops, and it is judged that the brake needs to be braked or retracted. At this time, the output of the comparator is a negative potential, which will be controlled by the main control core board. After the signal is processed, a command is issued to drive the motor to reverse the reverse direction, and the skater retreats. If braking is required, the motor can be operated in a power generation state, the power source can be charged, and the mechanical energy can be converted into electric energy. Of course, the coaster can also be stopped by using reverse braking or energy braking.

The comparator U1 in the present invention uses an op amp chip. Of course, the potential comparison function can also be implemented in the main control chip U2 by using a program, and the main control chip U2 uses the NM1530 core.

The voltage conversion module DC-DC in the present invention is used to adjust the DC voltage to a suitable value.
