The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, the utility model comprises the revolving door 1 that is installed on the rotation door-hinge 5, the dc brushless motor that is connected with rotation door-hinge 5 and the doorframe 4 that matches with revolving door; It is characterized in that: human body get into or Way out post the PVDF piezoelectric transducer assembly with the doorframe equal height near the doorframe side; The input of force feedback circuit is connected with the PVDF piezoelectric transducer; The output via controller of force feedback circuit is connected with dc brushless motor; Hall element in the dc brushless motor and controller are formed feedback circuit, realize the control of direct current brushless motor speed.
As shown in Figure 2, when the end effector finger surface that the PVDF piezoelectric transducer is housed began to touch object, the PVDF film was produced electric charge owing to contact the effect of step stress, through charge amplifier, generated the contacting feeling signal.Contact pressure is induced the caused signal of telecommunication, the control System Discrimination signal of telecommunication, the counter-rotating of control direct current generator, and then the action of control revolving door.
As shown in Figure 3; Described PVDF piezoelectric transducer assembly; Comprise by PVDF film (8) and be attached to the PVDF piezoelectric transducer that the copper sheet (7) of PVDF film both sides is formed that draw positive and negative electrode, PVDF piezoelectric transducer two sides is stained with electro-insulating rubber epidermis topping (6) respectively; Electro-insulating rubber epidermis topping with plane is attached near the doorframe side, has zigzag electro-insulating rubber epidermis topping towards human body.
As shown in Figure 4, described force feedback circuit comprises charge conversion circuit, low-pass filter circuit, power frequency trap circuit, gain adjusting circuit, A/D sample circuit; The signal of PVDF piezoelectric transducer is connected with the controller input behind charge conversion circuit, low-pass filter circuit, power frequency trap circuit, gain adjusting circuit and A/D sample circuit.
Signal processing circuit acquired signal process, when the sensor contact object of finger, or object is when sliding on its surface, sensor output charge signal.Adopt charge amplifier to convert charge signal into voltage and amplification, must carry out LPF then.There is tangible power frequency to disturb in the output signal, increases the notch filter of one-level 50Hz again.Filtering signal is amplified and analog-to-digital conversion.
