Description
Technical field:
The invention belongs to sewing machine technique field, refer in particular to a kind of arrangements for speed regulation with superpower antijamming capability.
Background technology:
Hall element is a kind of Magnetic Sensor.Magnetic field and change thereof can be detected with it, can use in the various occasion relevant with magnetic field.The speed regulator of Sewing machines is exactly the relative position utilizing Hall element and magnet steel, and the principle producing different voltage value carries out speeds control to motor.Its operation principle is: the single-chip microcomputer controlling motor, according to the voltage output value of the Hall element of speed regulator inside, goes to control the starting and stopping of motor and the rotating speed of motor by certain algorithm.But the switching over of the power device due to electric machine controller; produce the driving pulse comprising repeatedly high-frequency harmonic with abrupt change edge; and there is stray capacitance and inductance in the connection electric wire between controller and speed regulator; and produce damped oscillation by the excitation of certain subharmonic; therefore; the output signal of speed regulator is subject to very big interference; cause Sewing machines cisco unity malfunction; main manifestations is that operationally velocity perturbation is very large for motor; can not stop in time during shutdown; the phenomenon that cannot stop can be produced time serious, had a strong impact on quality and the serviceability of Sewing machines.Therefore need to carry out anti-interference process to speed regulator.
The anti-interference process of current speed regulator inside mainly the power supply of speed regulator inside, between add electric capacity and inductance, some resistance capacitances are added at Hall element periphery, such improvement also also exists certain weak point: the area not only increasing the inner PCB of speed regulator, and adds cost.
Summary of the invention:
The object of this invention is to provide a kind ofly effectively can filter various interfering signal, the reliability that greatly strengthens whole system, the arrangements for speed regulation with superpower antijamming capability that reduce system cost.
The present invention is achieved in that
Have arrangements for speed regulation for superpower antijamming capability, comprise the controller controlling motor speed and the speed regulator providing signal to controller, three of the Hall element in described speed regulator are parallel with electric capacity between pin and ground.
The pin 1 of above-mentioned Hall element is connected with power supply, pin 2 ground connection, between pin 3 and earth connection, be connected with electric capacity.
Capacity >=100 nanofarad of above-mentioned electric capacity.
The advantage that the present invention gives prominence to compared to existing technology is:
The present invention is by studying in great detail external disturbance and Hall element, propose a solution effectively, a filter capacitor is increased at the signal end of the Hall element of speed regulator inside, can effectively filter various interfering signal, and in Single Chip Microcomputer (SCM) program, special treatment is carried out to the signal of speed regulator, like this compared with current existing speed regulator system, strengthen the reliability of whole system widely, and decrease the cost of whole system.
Accompanying drawing illustrates:
Fig. 1 is principle schematic of the present invention;
Fig. 2 is the schematic diagram of Hall element of the present invention.
Detailed description of the invention:
With specific embodiment, the invention will be further described below, see Fig. 1-2:
Have arrangements for speed regulation for superpower antijamming capability, comprise the controller 20 controlling motor 10 rotating speed and the speed regulator 30 providing signal to controller 20, three of the Hall element 40 in described speed regulator 30 are parallel with electric capacity 50 between pin and ground.
The pin 1 of above-mentioned Hall element 40 is connected with power supply, pin 2 ground connection, is connected with electric capacity 50 between pin 3 and earth connection, and what electric capacity 50 adopted is filter capacitor.
As shown in Figure 1, the structure of controller 20 is as follows: power module 60 provides working power for each submodule.Single-chip microcomputer 70 controls modules co-ordination.Panel 80 for providing human-computer interaction interface, as display real-time speed, various optimum configurations etc.Speed regulator 30 is for controlling the speed of motor 10.Motor 10 operates for driving machine spindle.
When power device 90 receives the control signal of single-chip microcomputer 70, output drive signal controls the action of motor 10, because power device 90 is operated in the on off state of high frequency, externally can produce strong interfering signal.
The relative position that the magnet steel 100 of speed regulator 30 is different from Hall element 40 can make speed regulator 30 export different voltage values.Single-chip microcomputer 70, by the voltage of analog interface sampling speed regulator 30, changes into according to certain algorithm the voltage value sampled the order controlling motor 10 in inside.When the interfering signal interference being subject to power device 90, the signal meeting distortion sampled, causes whole system malfunctioning.
The present invention is between the pin 3 and ground of Hall element 40 and connect an electric capacity 50 output voltage of speed regulator 30 will be made substantially not to be subject to the impact of power device 90 interfering signal, strengthened the reliability of governing system further by the control algolithm of the improvement of single-chip microcomputer 70 simultaneously, because only have in the interference that power device 90 produces those High-frequency Interference can by power supply, holding wire etc. passes and comes, and after increasing this electric capacity 50, just can basic filtering interference signals.The capacity of electric capacity 50 is proper, generally be arranged on more than 100 nanofarads, select according to actual conditions, the interference that the electric capacity 50 of suitable capacity just can be coupled in this frequency range, because High-frequency Interference is straight-through load concerning electric capacity 50, interfering signals whole so has just been consumed by this electric capacity 50, and the frequency of useful signal is very low relative to this interference, signal useful so just can ignore electric capacity 50, normally carries out signal transmission.
Above-described embodiment is only one of preferred embodiment of the present invention, not limits practical range of the present invention with this, therefore: all equivalence changes done according to shape of the present invention, structure, principle, all should be covered by within protection scope of the present invention.
