Embodiment
The present invention is further described below in conjunction with drawings and Examples.
embodiment 1, and referring to figs. 1 through Fig. 4, a kind of street lamp is responded to local controlled standard energy efficient lighting system automatically, is comprised of intelligent control box 1, solar energy module 2, PWM light modulation driver module 3, lamp stand 4 and street lamp 5, wherein: thus intelligent control box 1 is by automatic inducing moving objects with receive extraneous DMX signal and control the brightness that the PWM light modulation driver module 3 of place street lamp is controlled the place street lamp, it is the brightest that street lamp reaches, the process of brightening can be carried out curve and major key is set is brightened, and when being arranged, mobile object can send to the external world DMX signal, the transmission frequency of selecting is 2.4Hz or 5.8Hz, the transmission radius is 150-500 rice, this scope is covered to looks younger with each street lamp of the left and right on control loop, allow back and the street lamp in scope brighten in advance and the time-delay of front and the street lamp in scope dimmed, during without mobile object and DMX signal, enter receiving state signal, intelligent control box is to the PWM instruction of the street lamp output 20% at place, and street lamp continues to light according to this ratio, simultaneously, also red, green, blue can be set, yellow, green grass or young crops, purple six indication looks number to the receiving and transmitting signal pairing as the DMX signal circuit, and the signal circuit of different numberings is separate, signal does not interfere with each other, the signal of red loop transceiver emission can only be accepted by the transceiver of redness, and the signal of green loop emission can only be accepted by the transceiver of green, by that analogy.
Described intelligent control box 1 comprise CPU6, DMX signal-processing board 7, DMX wireless receiving and dispatching plate 8, doppler sensor 9, level signal change-over panel 10, Voltage stabilizing module with 11, Switch power source 12 and DC12 interface 13; Solar energy module 2 comprises solar panels 15 and storage battery 14; The built-in PWM constant current plate 16 of PWM light modulation driver module 3 and constant voltage Switch power source.
Described intelligent control box is arranged on lamp stand, and L, N are connected with the electrical network input, also can access solar energy module, and PWM light modulation driver module is arranged in street lamp.
Described doppler sensor 9 is connected with level signal change-over panel 10, level signal change-over panel 10 is connected with CPU6, CPU6 one end is connected with outside main circuit, an other end is connected with DMX signal-processing board 7, DMX signal-processing board 7 is connected with DMX wireless receiving and dispatching plate 8, DC12 interface 13 is connected with solar energy module 2, and Switching Power Supply 12 is connected with the electrical network input.
the present invention is used on road, when moving object is arranged, because moving object stops wireless signal, and because the existence of self speed, changed the frequency of transmission of wireless signals, doppler sensor 9 output signals are to level signal change-over panel 10, CPU6 incoming level signal and carry out computing, to PWM light modulation driver module 3 input pwm signals, constant voltage and pwm signal are treated to the single channel constant current by the constant current IC that can accept pwm signal on PWM constant current plate 16, can provide constant electric current for each paths of LEDs like this, thereby intelligent control box 1 is regulated the adjusting that PWM realizes street lamp 5 brightness automatically, simultaneously, CPU6 also sends signal to DMX signal-processing board 7, processes by DMX signal-processing board 7, then sends the DMX signal of corresponding numbering by DMX wireless receiving and dispatching plate 8 to the external world, at this moment, the doppler sensor 9 of the intelligent control box 1 of several (scope can arrange) corresponding numberings of back is not also sensed mobile object, and DMX wireless receiving and dispatching plate 8 enters accepting state, to extraneous search signal, in the time of the DMX signal that sends when the intelligent control box 1 of receiving the corresponding numbering in front, intelligent control box 1 will be to the street lamp output 100%PWM luminance instructions at place, this order persistence 1 minute, or customize according to engine request, in the time of in mobile object moves to the scope that next intelligent control box 1 can sense, will repeat a process, in the situation that intelligent control box 1 is responded to less than mobile object and do not received DMX signal intelligent control box 1 to the PWM instruction of place street lamp output 20%, street lamp 5 continues to light according to this ratio, and this ratio also can customize according to project situation, arrange by this algorithm, road lamp system is transformed into an autonomous monitoring vehicle stream, and the road lamp system of independently brightness being adjusted calculates to carry out theory without the situation of vehicle pass-through, can save 80% electric energy nearly.
With reference to Fig. 5, the specific algorithm of the present invention when having or not mobile object is:
When 1, mobile object being arranged, CPU sends the PWM100% luminance instructions, street lamp 100% brightness; CPU sends the DMX signal to the instruction of DMX signal transmitting and receiving plate 001 path 10 0% brightness simultaneously.
When 2, having mobile object, DMX transceiver boards to receive the signal of DMX signal 001 path 10 0% brightness, street lamp 100% brightness.
When 3, receiving the signal of DMX signal 001 path 10 0% brightness without mobile object, DMX transceiver boards, street lamp 100% brightness.
4, without mobile object, when the DMX transceiver boards is not received the DMX signal, CPU sends the instruction that PWM keeps 20% brightness, street lamp 20% brightness.
Generally speaking, if at the induction range internal induction of doppler sensor to mobile object or
When receiving the DMX100% luminance signal in the range of receiving of DMX transceiver boards, street lamp 100% brightness, if when either way not existing, the street lamp brightness that street lamp keeps engineering to set is as 20% brightness or other.
With reference to Fig. 6, the employing wireless control loop of the present invention in street lamp arranges that schematic diagram is:
Highway both sides on direction of traffic is respectively equipped with the present invention of the different DMX signal circuits numberings such as B, G, R and Y, C, M, the street lamp of B, G, R or Y, C, three numberings of M as a bit of, the arrangement that circulates of highway afterwards and the street lamp of this segment, distance between the beginning street lamp of two segments remains in the range of receiving of DMX wireless receiving and dispatching plate, the distance of DMX wireless receiving and dispatching plate can be regulated according to requirement of engineering or environmental requirement, in order to determine to arrange the street lamp of several different numberings between a bit of distance, thereby reach the optimum state of arrangement.
Embodiment 2 is on intelligent control box with the difference of embodiment 1, removes DMX wireless receiving and dispatching plate, directly selects the doppler sensor of the distance of reaction of requirement of engineering, thereby realizes mobile object several street lamp 100% brightness of front and back.
In sum, after those of ordinary skill in the art reads file of the present invention, according to
Technical scheme of the present invention and technical conceive need not creative mental labour and make other various corresponding conversion scheme, all belong to the scope that the present invention protects.
