Description
Technical field
Light control field is by the on a large scale control of PLC technology realization to the LED light fixture.
Background technology
Along with people more come height for the degree of awareness of LED light fixture, its range of application is also more and more wider, relates to all trades and professions such as house, traffic, medical treatment, logistics, production.The well-known characteristics such as energy-conservation, durable that have except himself, speed of photoresponse, controllability also are by force the key factors that people select it.
Therefore the core of LED light fixture is light-emitting diode, is exactly a kind of electronic devices and components in fact, and easier realization is to the control of this class light fixture, and the mode of control is diversity more also, mainly based on brightness adjustment control.Present LED light fixture light modulation on the market at present adopts controllable silicon to regulate basically, but because the general efficient of power supply of LED light fixture is all lower, and can only realize substantially regulating one to one, and can't realize that one-to-many is regulated or multi-to-multi is regulated.Can't satisfy some adjustings of public domain usefulness lamp on a large scale.
Summary of the invention
In order to overcome above-mentioned difficulty, the invention provides the control system of the LED light fixture of a kind of interference-free, system stability, reliable, accurate positioning.
The present invention takes following technical scheme to realize: utilize power carrier to realize the LED light fixture is carried out the integrated system of Long-distance Control, comprise input module, A/D modular converter, power carrier sending module, power carrier receiver module, PWM control module; The connected mode of above-mentioned module is: described input module, described A/D modular converter and described power carrier sending module are formed light-adjusting module, described power carrier receiver module and described PWM control module are formed the control receiver module, described input module is connected with described A/D modular converter, described A/D modular converter is connected with described power carrier sending module, described power carrier sending module is connected with described power carrier receiver module, and described power carrier receiver module is connected with described PWM control module.
The present invention can also take following technical scheme to realize:
Described input module can for 1 also can be for a plurality of, and the information source terminal be installed in led light source two video cameras at the scene,
The mode that described A/D modular converter utilizes picture control to combine with computer vision technique is converted to digital signal with field condition,
Comprise the light source governor circuit in the described PWM control module, this circuit adopts the LM3402 chip.
Advantage of the present invention and beneficial effect are embodied in the following aspects:
1 owing to input module among the present invention adopts video camera as information source, simultaneously in the A/D modular converter, used computer vision technique, therefore can realize to by to led light source tracking and the analysis of moving object at the scene, simultaneously keep the low-light (level) level according to the moving object movement locus generation area that realizes moving not, the motion generation area is kept high illumination level, and then realize maximized energy-conservationly, and prolonged useful life of light fixture.
The locate mode that 2 picture controls are combined with computer vision technique can reliably be located the coordinate of object in the space on a large scale exactly, for the brightness of control light fixture provides reliable information.
3 owing to power application ZAP among the present invention is carried out the transmission of signal, therefore saves the expense that this system implements, and is convenient to safeguard.
