By means of the motor drive motor, power supply, control and management of a plurality of direct current motors in the same group of direct current power supply loop can be realized, and the motor drive circuit is suitable for multi-motor and multi-dimension controlled buildings, household electric devices and facilities.
Description
Technical field
The present invention relates to a kind of motor-drive circuit, be mainly used in and building and many motors of household electric device, the equipment of various dimensions control are realized power supply, controlled and management, as electric furniture, electrically driven curtain, power window etc.
Background technology
At present, what in most building, electronic facility adopted substantially is that fixed electrical machinery adds conveyor track mode, as electrically driven curtain, Electric sofa, power window etc., but along with intellectuality and the diversified development of facility in the building such as furniture, door and window, fixed motor can not meet changeable function application demand, as mobile door and window, active box (drawer) etc., simultaneously, also the flexibility characteristics adapting to install is difficult to, as DIY combined furniture etc.Therefore, removable motor driver will become the most feasible selection.But the Power supply and control of removable motor driver becomes again a large difficult point, in power supply, or use battery but the persistence that motor runs cannot be ensured, or outer active line but the convenience of fail safe and installation is difficult to again guarantee.In control, portable motor driver can only adopt wireless, but the wireless communication mode of routine cannot ensure the reliability of its communication and powerful networking capability.
Summary of the invention
Pin prior art of the present invention is not enough, provide realize the multiple direct current machines in same group of direct current power supply loop power supply, control and management, be suitable for many motors, building that various dimensions control and household electric device and facility.The supply line making full use of motor realizes, to the control and management of many group motors, achieving simple installation and reliable communication under safing prerequisite.
Technical scheme: a kind of motor-drive circuit, the direct-flow input end access rectifier bridge stack of any positive-negative polarity of bus, forms one of rectifier bridge stack output port of fixing both positive and negative polarity and rectifier bridge stack output port two after its rectification;
The input of single-pole single-throw(SPST relay is connected in two of rectifier bridge stack output port; One of normally closed output of dpdt relay connects one of rectifier bridge stack output port, the output port of two order single-pole single-throw relays of the normally closed output of dpdt relay;
One of normally closed output of dpdt relay and dpdt relay connect one of direct current machine input after often opening two short circuits of output; Direct current machine input two is connect after two of the normally closed output of dpdt relay often opens one of output short circuit with dpdt relay.
Microprocessor connects bus modem, single-pole single-throw(SPST relay and dpdt relay respectively.
Bus modem directly obtains from one of direct-flow input end or rectifier bridge stack output port and two of rectifier bridge stack output port the modulated communication signal coming from bus and input, and the signal after demodulation is sent to microprocessor, meanwhile, Microprocessor S3C44B0X instruction is sent in bus after modulating.
Microprocessor is implemented to control to the state of single-pole single-throw(SPST relay and dpdt relay by after the bus signals analyzing and processing coming from bus modem.
Single-pole single-throw(SPST relay realizes establishing by cable the confession of direct current machine and closing by microprocessor-based control.
Dpdt relay switches the polarity that direct current machine exports under micro-processor control, is in forward or reverse state to reach direct current machine.
Beneficial effect of the present invention: the present invention is directed to portable electric machinery control device and facility same group power and many motors in bus loop, various dimensions control and management, particularly for the removable storage space, packaged type power window, packaged type electrically driven curtain etc. of electric furniture, the present invention installs simple, safe and reliable, with low cost, has high practical value and universal value.
