In this paper, we consider the special demand for the person who hinders limb, construct a toe bending angles detecting device. The disability person can control the hand prosthesis with the bended change of the toe, to deal with daily life and the ability to promote independent life.
The detecting device is mounted with a bending sensor at each toe, and the bending sensor consists of IRED (Infrared Radiation Emitting Diode), silicone tubing and phototransistor. With different degrees of toe bending, it responses with luminous flux density variation and produces different signal values. A signal transformation module is used to transform the luminous signal into a voltage signal value. Transmitting this signal to Control circuit taking MCS-51 as the core, the analog signal of the toe bending is converted to a digital signal. The signal uses wireless transmit unit to convey to receive device, and we apply the standard RS-232 communication interface to acquire the data from the receive device. The data were sent to a personal computer for real-time showing on VB windows. Then, we utilize regression analyze to obtain the relation equation preface of the voltage and angle. And then make the relation equation preface determine the crooked angle change of the toes of disability person.
