the manual control mechanism moving position calculating module is used for calculating the actual moving position of the manual control mechanism based on the output signal of the position measuring unit to obtain the displacement change condition of the manual control mechanism;
and the hand grip resolving module identifies the hand grip of the operator based on the output signal of the force measuring unit and the set grip lower limit threshold. Namely, the hand grip force resolving module carries out calculation and identification through signals collected by the force sensor, judges the state of palm grip force change of an operator according to the value fed back by grip force data, and uses the state to control the moving speed of the manual control device in the passive mode of the rehabilitation mechanism.
In a specific embodiment of the present invention, the haptic interaction unit is a linear resonance actuator or a haptic actuator, and when it is determined that the manual control device is out of the set operation range or the grip strength of the operator is lower than the set threshold, the terminal device sends a control instruction to start the haptic interaction unit to provide corresponding reminding feedback, that is, the haptic interaction unit performs haptic interaction with the operator to provide an operation prompt for the operator, and provides a corresponding haptic interaction prompt at the moment when the operator reaches the limit operation range and releases the handle of the manual control mechanism in the passive training mode.

When the resolving module of the terminal equipment fails to resolve, namely the movement range of the manual control device of an operator exceeds the resolving range or the hand holding power of the operator is lower than the preset threshold range, an instruction is sent to the touch interaction unit of the handle of the manual control device through the wireless data communication unit to carry out hand reminding, and an instruction is sent to the force feedback control driver at the same time, so that the transmission linear servo motor of the controlled mechanism generates a reaction force to prevent the manual control device from continuously moving outwards.
In a specific embodiment of the present invention, the force feedback unit includes a servo motor and a force feedback control driver connected to each other, and when it is determined that the manual control device is out of the preset movement range, the terminal device sends a control command to enable the force feedback unit to generate a force opposite to the movement trajectory of the manual control mechanism, so as to prevent the manual control device from continuing to move outward, limit the movement of the manual control device out of the preset range, protect the mechanical structure of the manual control device, and avoid mechanical damage.
