Abstract
The invention discloses an intelligent control system of an LED (Light-Emitting Diode) city public illumination lamp, comprising an upper computer, a communication module, a sensor group, a microprocessor, a power adjusting circuit, an LED drive and a dimmable lamp, wherein the microprocessor is connected with the upper computer through the communication module; the sensor group is connected with the microprocessor; and the microprocessor is connected with the LED drive and the dimmable lamp through the power adjusting circuit. The intelligent control system has the advantages that pedestrian or vehicle information is obtained by the microprocessor through a video sensor; the adjacent lamps are lightened in advance through the communication module so as to achieve a pre-illuminating function; when no pedestrians or vehicles exist, a standby micro-power illumination state is delayed; and the requirements of road illumination are met through the intelligent control system and electric energy is saved.
Description
Technical field
The present invention relates to a kind of light fixture intelligence control system, especially relate to a kind of LED city luminaire for public lighting intelligence control system.
Background technology
The electricity consumption of present many cities public illumination is in the controlled state of extensive style, exists big defective, causes waste of electric energy.Even if adopted some power-economizing methods or equipment, such as closing midnight, this lacks safety guarantee; At a distance from one bright one or at a distance from two bright one, this can cause road lighting inhomogeneous; Adopt the compensator transformer step-down, light source life can be influenced; Need be equipped with special-purpose modes such as Power Regulation ballast but become power, this is a cost to reduce road illumination.Bright lamp rate has become the tender subject that the people extremely pays close attention in the public illumination of city on the other hand, and the general local visiting method that adopts is wasted man-hour, and can not in time be found damaged condition.The energising of carrying out after daytime light fixture being keeped in repair detects, and takes for mismanagement, has only the bright lamp rate that improves city illumination just can obtain good social effect.The pressure of energy-saving and emission-reduction aspect has to lighting time is controlled, and social benefit and economic benefit can not be taken into account.Suburb or newly-built people from development zone vehicle flowrate are few, and the north almost can not see the pedestrian later at 10 in evening, and at the latest also with regard to 12 o'clock, seasonality is particularly outstanding in the inner city, for few part pedestrian street lamp Chang Liang, cause a large amount of wastes of the energy.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can satisfy lighting requirement, the LED city luminaire for public lighting intelligence control system that can economize on electricity again,
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of LED city luminaire for public lighting intelligence control system; It is characterized in that comprising that host computer, communication module, sensor groups, microprocessor, power conditioning circuitry and LED drive and the tunable optical light fixture; Described microprocessor is connected with described host computer through communication module; Described sensor groups is connected with described microprocessor, and described microprocessor drives with described LED through power conditioning circuitry and the tunable optical light fixture is connected.

Described power conditioning circuitry comprises AC input circuit, filtering and rectification circuit, passive power factor corrective circuit, isolating transformer, photoisolator and constant-flow driver; The AC input circuit is connected with the passive power factor corrective circuit through filtering and rectification circuit; The passive power factor corrective circuit is connected with constant-flow driver through isolating transformer; The pwm signal output of microprocessor is connected with constant-flow driver through photoisolator, and constant-flow driver drives with LED and the tunable optical light fixture is connected.
Also comprise radio receiving transmitting module, described radio receiving transmitting module is connected with described microprocessor.
Also comprise automatic failure detection circuit; Described automatic failure detection circuit comprises described host computer and described current sensor; Described current sensor is connected with constant-flow driver; Detect the current value of constant-flow driver, be sent to the A/D unit of microprocessor after the amplification of current value process, the Filtering Processing, microprocessor sends to host computer with digital signal after treatment through radio receiving transmitting module.
Also comprise the electric power facilities anti-theft detection module, described electric power facilities anti-theft detection module comprises described host computer and described radio receiving transmitting module, and host computer passes through the described radio receiving transmitting module communication state of poll microprocessor at set intervals.
Described communication module comprises wired communication bus, JTAG debugging interface and internet interface.
Compared with prior art; The invention has the advantages that microprocessor passes through video sensor and obtains pedestrian or information of vehicles, adjacent light fixture is lighted, reach the function of illumination in advance through communication module; After not having pedestrian or vehicle; Time-delay gets into standby micropower illumination condition, has both satisfied the demand of road lighting through intelligentized control system, has saved electric energy again.
Gather pavement image in real time; When moving target and dynamic benchmark have difference output; Control system is through calculation process, and light fixture produces response, sends the specific protocol packet through the data link between the light fixture; The control system of the adjacent light fixture in the notice left and right sides is transmitted packet, reaches the prevision illumination purposes.After target disappeared, the setting standby power is closed or be reduced to light fixture, satisfies basic brightening effect.In pavement image acquisition process process; The translational speed of considering vehicle can reach 42m/s; Have only under the sample rate of the satisfying 30fps situation just can reach identification requirement, high to processor requirement, its operational capability can not be lower than 20MIPS; And through the optimization aim extraction algorithm, thereby realize the control of throwing light on as required of single lamp.
