Manually and the automatic-switching type Lighting Control Assembly

Technical field

The invention belongs to control device, particularly a kind of manual and automatic-switching type Lighting Control Assembly.

Background technology

At present, develop rapidly along with China's economy, the day by day shortage of the non-renewable energy resources such as coal, oil, natural gas, national energy, supply of electric power growing tension, the phenomenon that can waste electric energy still exists, and as all existing the people from lamp bright phenomenon still in the campus and in community illumination or the classroom, and existing illuminating lamp majority is manually to open and close by the people to control, seldom there is intellectuality and automation control to throw light on, so not only wasted electric energy but also waste money.

Summary of the invention

The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of and can satisfy various occasion lighting requirements, saves energy, manual and automatic-switching type Lighting Control Assembly easy to use.

The technical scheme that technical solution problem of the present invention adopts is: manual and automatic-switching type Lighting Control Assembly comprises RS485 network, RS232/RS485 transducer, PC software platform, be characterized in connecting the RS232/RS485 transducer at two-wire RS485 network, RS232/RS485 transducer two-wire connects the PC software platform, connects several controllers one, two, three, four at two-wire RS485 network ... N; Each single controller connects to form by lower column circuits: adopt the ATMEGA128 single-chip microcomputer as control circuit in the controller, power circuit in the controller, photoelectric detective circuit, infrared thermal release electric human body detection circuit, address encoding circuit, system clock circuit, manual switch circuit, crystal oscillating circuit, reset circuit, program download circuit all unidirectional output connects control circuit, the unidirectional output of control circuit connects the control relay drive circuit, the front panel circuit, the unidirectional output of relay drive circuit connects the control lighting apparatus, and RS485 bus transmission circuit is connected with the RS485 network bi-directional.

The invention has the beneficial effects as follows: manually and the automatic-switching type Lighting Control Assembly by the light in photoelectric sensor and the infrared thermal releasing human body detection module collection field of illumination, the information such as personnel's distribution, lighting apparatus is realized intelligent control, can be under the prerequisite that satisfies the normal illumination demand, saves energy effectively, native system is applicable to the classroom in the campus, the illumination control in dormitory and the biotope, be provided with automatic and hand switch in the control system, easy to use.
