Abstract
The invention provides a dual-power supply control switch of a motor. The dual-power supply control switch comprises a control chip, an optical coupler and a bidirectional silicon-controlled rectifier, wherein a main power supply controls the motor to positively rotate through the control chip, the optical coupler and the bidirectional silicon-controlled rectifier, and a standby power supply controls the motor to reversely rotate through the control chip, a standby optical coupler and a standby bidirectional silicon-controlled rectifier. In the dual-power supply control switch, the optical coupler and the silicon-controlled rectifier are used for controlling dual power supplies, the space occupancy can be effectively reduced, the area of a printed circuit board is reduced, and a product can be more compact; meanwhile, the weight of the silicon-controlled rectifier is light, and the product can be higher in portability; the duty ratio of the optical coupler is adjustable, and the optical coupler is high in interference resistant capability and high in isolation between strong electricity and weak electricity; and moreover, the optical coupler belongs to a current type device, and the voltage noise can be effectively suppressed.
Description
Technical field
The invention belongs to electronic control technology field, especially relate to the two power control switch of a kind of motor.
Background technology
In prior art, the switch device of the two power control switch many employings physical construction of motor, volume is big, relatively heavy, restricted lifetime, time of response is long, line construction is more complicated, so how designing the problem that the two power control switch of motor machine that a kind of volume is little, weight is light, circuit is simple, cost-saving becomes those skilled in the art's research.
Summary of the invention
In view of this, the present invention is intended to propose the two power control switch of motor machine that a kind of volume is little, weight is light, circuit is simple, cost-saving.
For achieving the above object, the technical scheme of the present invention is achieved in that
The two power control switch of a kind of motor, comprise primary source part and standby power supply part, CPU controls the anode of the key light coupling of described primary source part, the plus earth of described key light coupling, the collector electrode of described key light coupling connects 5V power supply through a resistance, the emtting electrode of described key light coupling connects the control pole of main bidirectional thyristor, and during described main bidirectional thyristor conducting, motor rotates forward; Described CPU controls the anode of the standby optocoupler of described standby power supply part, the plus earth of described standby optocoupler, the collector electrode of described standby optocoupler connects 5V power supply through a resistance, and the emtting electrode of described standby optocoupler connects the control pole of standby bidirectional thyristor, motor reversal during described standby bidirectional thyristor conducting.
Described optocoupler model is TLP290.
Described silicon controlled rectifier model is BTA12-800B.
The model of described CPU is STM8S005K6.
Relative to prior art, the two power control switch of motor of the present invention has following advantage:
1. the present invention adopts optocoupler and silicon controlled rectifier to be controlled by two power supply, it is possible to effectively reducing the taking of space, the product that simultaneously makes of the area reducing pcb board can be smaller and more exquisite, and the weight of silicon controlled rectifier is light simultaneously, it is possible to allow product can Portability better;
2. opticcoupler dutycycle is adjustable, and its immunity from interference is strong, and the isolation performance between strong and weak electricity is fine, and in addition, optocoupler belongs to current mode device, can effectively be suppressed by voltage noise.
3. traditional transformer and rly. belong to power device, there is the phenomenon burning out motor when in use, and it is too heavy and repair and replacement are quite loaded down with trivial details, while removing rly., transformer can be taken away after using silicon controlled rectifier to replace rly., this not only greatly reduces the weight of controller entirety, also reduce the difficulty of maintenance operation, whole pcb board almost can all use surface mount elements, remaining direct insertion element can be easy many when pipelining, it is to increase output also reduces hidden danger.
4. the present invention can also save the diode that absorbs inverse electromotive force, it is possible to reduces the use of element, thus reduces the probability and cost made mistakes.
