Abstract
The invention discloses a balance chair controller which comprises a box. A multi-axis gyroscope sensor is connected with the side wall of a side of the box, an ultrasonic distance measuring sensor isarranged on a side of the multi-axis gyroscope sensor, an electric quantity acquisition sensor which is connected with a side wall of the box is mounted on a side of the ultrasonic distance measuringsensor, a circuit board is arranged inside the box, a CPU (central processing unit) is connected onto the circuit board, a motor driver is arranged on a side of the CPU, and a buzzer is arranged on aside of the motor driver. The balance chair controller has the advantages that current chair posture can be sensed by the gyroscope sensor, and chair states can be adjusted by wheelchair driving execution components (push rod motors) to have initial values after Kalman filtering setting is carried out; vehicle operating states can be measured and calculated by vehicle backing radar of wheelchairsby the aid of gyroscope modules, and users can be prompted for rear obstacle conditions according to ultrasonic distance measuring results if the vehicle operating states are vehicle backing states;motors can be controlled by the motor driver by the aid of PID (proportion, integration and differentiation) methods, and accordingly the system response speeds can be obviously increased.
