Description of drawings

Fig. 1 is the Organization Chart of the supervisory control system of the utility model embodiment;

Fig. 2 is the structural representation of the utility model embodiment sub-controller.

Embodiment

Be further described below in conjunction with accompanying drawing and the utility model of embodiment.

Embodiment of the present utility model is with reference to shown in Fig. 1-2, a kind of LED light fixture supervisory control system, comprise central controller, wireless device and sub-controller, described central controller carries out wireless telecommunications by wireless device and several sub-controllers, each sub-controller is connected with street lamp and/or Landscape Lamp by control loop respectively, and described sub-controller comprises power module, single-chip microcomputer and peripheral circuit thereof, RS232 communication interface, contactor drive control module, clock module, illuminance detection module, analog quantity testing circuit and Man Machine Interface.Wherein, central controller is PC, and described wireless device is the radio station.

Each intelligent controller is controlled 26 street lamps or 26 public lighting circuits respectively among Fig. 1.The number of intelligent controller is determined by PC in the system.This system mainly contains following function: distant control function, telemetry function, remote signalling function and warning function.

Distant control function: the scene table that will manually define, scheme table, dispatch list, primary and secondary loop configuration table, detect the parameter relevant with control such as loop configuration table and illumination pattern list and be stored in the PC, and time pass in the intelligent controller foundation as this part control strategy.If no special circumstances, intelligent controller is first to be gathered the data that the data of returning and illumination pattern list set according to the illuminance detecting unit and compares analysis, can determine a kind of in five kinds of patterns such as fine day, cloudy, cloudy, overabundant yin sky, night.Preceding four kinds of patterns are corresponding its scene directly.Yet at the pattern in night, controller also needs according to scene table, scheme table and dispatch list, obtains the scheme of execution in night on the same day, automatically performs corresponding road lamp switch scene according to the time and moves.Can manually control remote control open and close lamp in addition by the man-machine interface of PC at any time to each intelligent controller.

Telemetry function: operating personnel carry out data acquisition to each intelligent controller at any time by manual operation, and the data of collection comprise that each intelligent controller is in data such as the voltage in this moment, electric currents.And operating personnel can also detect the ruuning situation of street lamp under each intelligent controller at any time, and demonstrate geographical position and the whether normal state of operation thereof at its place in man-machine interface.

Remote signalling function: carried into execution a plan real-time time, parameter configuration table, the same day that intelligent controller can be inquired about by Surveillance center, alert data, illumination data etc., so that operating personnel understand operating state and the operational factor of each intelligent controller.

Warning function: intelligent controller carries out data acquisition at set intervals, and by analyzing the data that collect, whether judgment device breaks down then.If abnormal conditions occur, intelligent controller is closed corresponding street lamp immediately, and reports to the police to Surveillance center, shows corresponding alarm region and warning reason in man-machine interface.

For the structure of sub-controller as shown in Figure 2: single-chip microcomputer is the AVR single-chip microcomputer, described clock o'clock circuit, RS232 communication interface and single-chip microcomputer are respectively two-way communication, described contactor drive circuit is controlled by Micro Controller Unit (MCU) driving, described power module is powered to single-chip microcomputer, described analog quantity testing circuit and illuminance detection module are carried signal to single-chip microcomputer respectively, described Man Machine Interface comprises liquid crystal display circuit and keyboard interface, and described liquid crystal display circuit and keyboard interface are controlled by single-chip microcomputer respectively, also are connected with debugging interface on the described single-chip microcomputer.

The above execution mode has only been expressed a kind of execution mode of the present utility model, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.
