Abstract
The invention provides a small-size dual-power control switch, and the switch comprises a control chip, triodes, and bidirectional silicon controlled rectifiers. A main power supply controls the forwarding rotation of a motor through the control chip, the main triode and the main bidirectional silicon controlled rectifier. A standby power supply controls the reverse rotation of the motor through the control chip, the standby triode and the standby bidirectional silicon controlled rectifier. The switch achieves the control of double power supplies through the triodes and the silicon controlled rectifiers, can effectively reduce the occupied space, reduces the size of the area of the PCB, enables a product to be smaller and more exquisite, enables the weight of the silicon controlled rectifiers to be light, and enables the portability of the product to be better. The triodes are high in control speed, and the control time is commonly hundreds of ns or shorter. The switch can receive signal and be switched off in a short time, so the switch can play a good role in quickly switching on/off a circuit.
Description
Technical field
The invention belongs to electronic control technology field, especially relate to a kind of small capacity double power control switch.
Background technology
In prior art, the switching device of small capacity double power control switch many employings physical construction, volume greatly, heavier, restricted lifetime, response time is long, line construction is more complicated, so how to design the problem that a kind of volume is little, lightweight, the response time is short, circuit is simple, cost-saving motor small capacity double power control switch becomes those skilled in the art's research.
Summary of the invention
In view of this, the present invention is intended to propose the motor small capacity double power control switch that a kind of volume is little, lightweight, the response time is short, circuit is simple, cost-saving.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of small capacity double power control switch, comprise primary power part and standby power supply part, CPU controls the base stage of the main triode of described primary power part, the collector of described main triode connects 5V power supply through a resistance, the emitter of described main triode connects the control pole of main bidirectional triode thyristor, and during described main bidirectional triode thyristor conducting, motor rotates forward; Described CPU controls the base stage of the standby triode of described standby power supply part, and the collector of described standby triode connects 5V power supply through a resistance, and the emitter of described standby triode connects the control pole of standby bidirectional triode thyristor, motor reversal during described standby bidirectional triode thyristor conducting.
Described triode model is 9014.
Described controllable silicon model is BTA12-800B.
The model of described CPU is STM8S005K6.
Relative to prior art, small capacity double power control switch of the present invention has following advantage:
1. transformer and the excessive problem of relay footprint area ratio are all need to solve all the time.The present invention adopts triode and controllable silicon to control dual power supply, can effectively reduce taking of space, makes product can be smaller and more exquisite while reducing the area of pcb board, and silicon controlled is lightweight simultaneously, and product portability can be allowed better.
2. triode control rate is fast, and generally even shorter at hundreds of ns, can complete break-make at short time acknowledge(ment) signal, this can play good effect in the circuit needing quick on-off.
3. traditional transformer and relay 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 removal relay, transformer can be taken away after using controllable silicon replacement relay, this not only greatly reduces the weight of controller entirety, also reduce the difficulty of maintenance operation, whole pcb board almost all can use surface mount elements, remaining direct insertion element can be easy to be many when pipelining, improve output and reduce hidden danger.
