Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1: the present invention includes field coil for motor, first rectification circuit, tech-generator, shaking table, optoelectronic switch, logical circuit, the time relay, electronic switch, motor, tech-generator and the second rectification circuit, one end of field coil for motor connects the test the speed positive pole of given voltage and the positive pole of the given voltage of frequency measurement, the negative pole of given voltage of testing the speed is connected with the first end of the first rectification circuit, the negative pole of the given voltage of frequency measurement is connected with the first end of the second rectification circuit, second end of the first rectification circuit is connected with the first end of tech-generator, second end of tech-generator is connected with the second end of field coil for motor and the first end of shaking table simultaneously, second end of shaking table is connected with the first end of optoelectronic switch, optoelectronic switch, the time relay is all connected with logical circuit with the first end of electronic switch, and the second end of electronic switch is connected with the first end of motor, and the second end of motor is connected with the second end of the second rectification circuit by tech-generator.
Field coil for motor is with dynamic load to rotate under the given function of current, produces and periodically vibrates.The output of motor constantly adjusts via two feedback circuits.First, the output of motor passes to the tech-generator coaxial with it and produces ac voltage signal, and this signal obtains d. c. voltage signal through overcommutation and sends into logical circuit.The output of logical circuit is the motor input signal readjusted.This circulation is the negative-feedback circuit that tests the speed.Secondly, the vibration of shaking table triggers optoelectronic switch and produces periodic pulse signal, the time that this signal period sets with the time relay compares, judge jarring machine vibration frequency size, thus triggerable electronic switch is modulated the motor input voltage on this branch road, by changing the rotating speed of input power average voltage adjustment motor, and then change the output signal of tech-generator, this signal is by the second rectification circuit, logical circuit is delivered to the form of DC voltage, participate in the speed adjustment of motor, form jarring machine vibration frequency closed-loop control device PL thus.
Embodiment is as shown in Figure 2: jarring machine vibration frequency closed-loop control device PL coordinates with peripheral circuit, and completion system starts, suspend, stop, and carries out the operation such as test period, test frequency setting.In figure, D1, D2, D3, D4 are respectively red, yellow, green and red, and the information of its representative is power-off, time-out, energising and clearing, and KT1 is the intelligent digital time relay, and KT2 is timing relay.
The present invention will modulate feedback motor input voltage by bumper vibration frequency, the feedback voltage relevant to vibration frequency is obtained by tech-generator, with the reference voltage standard of this voltage correction motor negative feedback control loop, thus form the closed-loop control of bumper vibration frequency.The technical matters solved have following some:
(1) rational vibration frequency feedback model is set up
The feedback of native system comprises two parts: the negative feedback (negative feedback of testing the speed) of adjustment motor output speed and the negative feedback (frequency measurement negative feedback) of adjustment bumper vibration frequency.Wherein the adjustment of vibration frequency is obtained by the reference voltage revising the negative-feedback circuit that tests the speed.The negative-feedback circuit that tests the speed during motor output shaft load change maintains the stable of output speed by exciting current in adjustment coil.When bumper vibration frequency changes because of the factor such as belt slip, load change, the output of feedback circuit at the corresponding levels is changed by the change of vibration frequency, the reference voltage of negative-feedback circuit and the output correction of feedback circuit at the corresponding levels is tested the speed, thus change the output speed of motor, and then the vibration frequency of bumper is adjusted automatically.
(2) switching signal is converted to suitable feedback signal
Switching signal directly as the feedback signal of circuit, can not must carry out suitable conversion.By switching signal and time signal are combined, judge switching signal and switching signal is incorporated into motor power input circuit, changing input circuit average voltage by switching signal, thus affect the output speed of motor.The tech-generator be positioned on motor output shaft is experienced this change and this change transitions is become the change of voltage.This voltage and frequency measurement negative-feedback circuit reference voltage compare, and its result, for revising the reference voltage of the negative-feedback circuit that tests the speed, forms negative-feedback circuit.
(3) choose reasonable hardware system, design system parameter carry out verification experimental verification
According to the factor such as system loading, environment for use, select the hardware of suitable parameters.According to selected hardware parameter, detailed design system control parameters, as reference voltage, negative feedback gain etc.After system building completes, security of system test to be carried out under the permissive conditions such as mains voltage variations, variation of ambient temperature, load variations, whether the environment ability to bear of checking system meets the demands, and anti-locking system is out of control, adjusts hardware or design parameter if desired.
