Embodiment
The long-range change Optimizing Control System of street lamp comprises that rack manipulation portion and lamp carry control part.Known referring to Fig. 3, rack manipulation portion is the rack of controlling a section street lamp power supply, road lamp power supply circuit, be provided with the button and the key circuit thereof that represent different power on/off number of times, key circuit outputs signal to control unit, this control unit can adopt chip STC12C5608, control unit produces and exports instruction electricity according to the Signal coding of the key circuit receiving, and controls performance element work, and performance element carries out several power on/off operation continuously to street lamp supply line.Performance element comprises output isolated controlling parts photoelectrical coupler, and output execution unit field-effect transistor.
Known referring to Fig. 1, lamp carries control part to be located in all street lamps of institute of rack manipulation portion control circuit, it comprises city's power detection circuit of being located at road lamp power supply input, this circuit is processed and judges continuous power on/off signal in the certain hour of supply line, and will judge that information conveyance is to main control chip, main control chip can adopt chip STC12C5608AD, main control chip outputs control signals to output power Circuit tuning, by the constant current control of LED street lamp and lamp plate drives street lamp brightness power sequential.Use for fear of the frequent flicker effects of street lamp in the time receiving power on/off signal, between city's power detection circuit and light source, be provided with Switching Power Supply, and be connected with main control chip by street lamp input power control unit, thereby in the time receiving make-and-break signal, close road-light light-source.Road-light light-source is LED, can be by PWM(pulse duration adjustment modes) mode adjust its bright light power output.
Utilize above-mentioned rack manipulation portion and lamp to carry the long-range change light control method of street lamp of control part as follows:
Rack manipulation portion presets several street lamp bright light power time series patterns, the continuous power on/off of the corresponding different number of times of each bright light power time series pattern, each bright light power time series pattern is equipped with a button, opening before street lamp, select corresponding button by control personnel according to needs, then press start button.At this moment street lamp interchange control cubicle is sent with selected control and is numbered corresponding coding by specific switching electricity mode, i.e. continuous power on/off for several times, if break-make is exactly for 3 times the signal of power time series pattern two; Break-make is exactly for 4 times power time series pattern three (the bright light power time series pattern table that concrete every kind of pattern is corresponding) signal etc.
For example bright light power time series pattern is as follows:
Wherein red-letter day, pattern was omnidistance total power system, and winter mode refers to March annual November to next year during this period of time; Summer mode is applicable to annual April to October.
Lamp carries control part according to the power on/off number of times of rack manipulation portion, be provided with it identical street lamp bright light power time series pattern, when carrying control part, lamp detects that supply line exists continuous power on/off phenomenon, calculate power on/off number of times, and according to the selected corresponding bright light power time series pattern (preset value of this number of times, set model and pattern count as required, but must unify with rack manipulation portion data), and by performance element control street lamp power stage.Specifically, connect after judgement place power on/off number of times, wait routine is set coding, sets output services sequential after settings code is write to EEPROM, selectes corresponding bright light power time series pattern afterwards, and carry out power stage control according to this sequential.
Rack manipulation portion exports before the control command of continuous break-make road, street lamp circuit should be in off-position, therefore selecting after a bright light power time series pattern, rack manipulation radicals by which characters are arranged in traditional Chinese dictionaries are first switched on a period of time, enter again set model, carry out power on/off output, wherein the length of above-mentioned energising a period of time should be less than energising threshold values, and energising threshold values is that lamp carries control part and determines whether just to open street lamp state;
Lamp carries the energising threshold values that control part is preset with and can be set to about 3 minutes, energising threshold values can avoid the accident in path process to open circuit, or voltage fluctuation and the wrong bright light power time series pattern that enters that causes is selected, only in the time just opening street lamp, just carry out model selection, therefore carry after control part initial work at lamp, first to judging conduction time before, if be less than just once power-off generation of threshold values conduction time, carry out the detection of power on/off number of times, if be greater than threshold values, carry out last time power time series pattern bright light, and exported by performance element power ratio control.If use and press system default power time series pattern one for the first time.
Light source frequently glimmers when selecting bright light power time series pattern, in the time that lamp carries control part and judges that power-off time is less than threshold values, cuts off street lamp power supply, road lamp power supply loop, and is judging closed circuit after bright light power time series pattern.
The corresponding different continuous power on/off number of times of bright light power time series pattern is all greater than 2 simultaneously, can avoid the accident in path process to open circuit, or voltage fluctuation and the wrong bright light power time series pattern that enters that causes is selected, detect continuous power on/off number of times and be less than 2 when lamp carries control part simultaneously, predicate invalid data, continue to detect power on/off number of times.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
