Background technology:
At present, the intelligent transportation apparatus for deivation is all introduced in intelligent traffic lamp control and intelligent traffic administration system field.Such device is various in style, and screen or the like is induced in outdoor LED large-size screen monitors, urban road crossing, and outdoor LED large-size screen monitors expense height is fit to the changeable occasion of information indicating; The urban road crossing is induced screen to be mainly crossing traffic guiding is provided, and works long hours, and the brightness no requirement (NR) can't be satisfied under the mal-condition (as wind sand environment), need add the high-power requirement of inducing the brightness of board light-emitting area to increase that makes.
Along with greatly developing of the industrial revolution of modernization, amblent air temperature has been subjected to great changes.Strong wind severe snow, sandstorm, thick fog weather often appear in western China, the Northeast, East China, South China.Under such inclement weather conditions, driver drives vehicle safety can not get ensureing, and is dangerous big.Generally to point out with warning lamp, safety standard, just can safety.
Summary of the invention:
The utility model provides a kind of employing light-operated technology, and according to the temporal information that the GPS module provides, comprehensive current wind speed is judged the current weather situation, and maneuver traffic induces the adaptive placed arrow type intelligent transportation of light-emitting area brightness of warning lamp to induce warning lamp automatically.
The utility model is achieved by the following technical solution: warning lamp is induced in the adaptive placed arrow type intelligent transportation of a kind of light-emitting area brightness, and its major technique feature is that it comprises power unit, control section, LED luminous component, housing parts and anti-dust part; It is that to connect the GPS time signal that the chip model is SKG17, photosensitive control module, wind speed detection module, wave point receiver module, chip respectively be the brilliance control output module of 74HC595 for the main control module of STC10C04 by model;
Described brilliance control output module is made of with the general triode 5551 of NPN type positive-negative-positive phototriode and amplification; It is to adopt blink states that warning lamp is induced in described placed arrow type intelligent transportation, and autoluminescence face adopts yellow and red LED pipe, and tow sides post superpower reflecting film, and are promptly red and white.
The utility model adopts light-operated technology, and according to the temporal information that the GPS module provides, comprehensive current wind speed is judged the current weather situation, and maneuver traffic is induced warning lamp automatically.Brightness on daytime reduces, wind speed strengthens, open automatically when visibility reduces or add the high-power brightness that makes light-emitting area, guide car is popular sail in the right direction; Night, warning lamp was induced in startup, and brightness can suitably reduce; Warning lamp can be set to close automatically under the high situation of the normal visibility of brightness on daytime, and saves energy effectively better increases serviceable life of warning lamp, and this system cost is cheap, and is easy to use.The utility model provides wind light mutual complementing interface and advanced battery charge controller, provides the RS-232 communication interface remote controlled as required.The utility model makes every effort to accomplish circuit simplification, stable performance, complete function, simple installation, and under intelligent transportation control and management domain rugged surroundings, the intellectual inducing aspect provides the placed arrow type intellectuality of high performance-price ratio and perfect in shape and function to induce warning lamp.

Embodiment:
As shown in Figure 1 and Figure 2, warning lamp is induced in the adaptive placed arrow type intelligent transportation of this light-emitting area brightness, and it comprises power unit, control section, LED luminous component, housing parts and anti-dust part; It is that to connect the GPS time signal that the chip model is SKG17, photosensitive control module, wind speed detection module, model respectively be the serial line interface RS-232 of MAX232 chip, the brilliance control output module that chip is 74HC595 for the main control module of STC10C04 by model.The powering mode of power unit employing wind energy and sun power complementation, because the big regional wind-force aboundresources of dust storm, the sunshine-duration is longer, the power supply mode of using wind-force and solar electrical energy generation complementation is relatively rationally with effective.Control section comprises light-operated part, wind speed test section, main control part.
In Fig. 2, Fig. 3,1. be wave point receiver module (ZF02-9600P), receiver module is selected general module, its output signal is for walking signal, directly deliver to P0.1 and the P0.2 port of STC10F04, use the software read port, input-buffer, obtain one group of data, the modification system needs the display message group number also can provide period configuration information.2. be the gps signal receiver module, SKG17 is the GPS module, and MAX232 is the serial signal output interface chip.3. be the brightness detection module, this module is made up of the positive-negative-positive phototriode and is amplified and form with the general triode 5551 of NPN type, and output detects the P0.3 mouth of voltage to STC10F04.4. be the wind speed detection module, this module sensors adopts air velocity transducer module, as 8455 grades all can, output detects voltage to the P0.4 port.5. be the CPU module, comprise STC10F04 single-chip microcomputer, MAX232 serial communication chip and IO mouth.6. be autoluminescence backlight lightening module.STC89C51 control 74HC595 drive point shiny red or yellow LED lamp.
As shown in Figure 4, system scheduling module is responsible for the collaborative work of each module of system, rational allocation system resource.Data transmission adopts wireless communication module to revise self-defined period information by the RS-232 data-interface, is provided with according to the period and calls basic brightness configuration information.The GPS message processing module obtains the GPS relevant information, extracts the time related information that this device needs.Photosensitive data acquisition module converts one of parameter of control brightness according to what come from the P0.3 port processing to because of looking after the different voltage datas that produce of intensity.The air speed data acquisition module generates another parameter of controlling brightness according to the voltage, the current data value that produce because of different wind speed from the P0.4 port processing.The light emitting control module is lighted and is controlled light-emitting area brightness or extinguish light emitting module according to period configuration information decision.The native system Installation and Debugging are convenient, need not senior specially trainings, and common electrician can finish relevant the installation and configuration operation.This product adopts absolute construction, and system stability is reliable.
As shown in Figure 5, the LED light-emitting area is made up of the high-brightness LED pipes of redness and yellow two kinds of colors, alternately dodges three kinds of patterns by the yellow sudden strain of a muscle of control generation of driving circuit, red sudden strain of a muscle and reddish yellow.The housing parts tow sides post the superpower reflecting film of U.S. 3M, i.e. and red (1) and white (2), arrow pattern and reflective membrane distribute as shown in Figure 5, under the automotive lamp irradiation, play effective warning function.
This system adopts STC10F04 as master controller, has finished the development and Design of hardware electrical equipment and software, and realization is glimmered, luminous this system extension of display alarm function is convenient, convenient and safe, effect obvious, obtained good social benefit.As the energy, photoresistance is as photo-sensitive cell with sun power and wind energy complementary, and LED is as the light emitting source of high brightness, just flushing, the yellow intersection glimmers, the complete red flicker of reverse side, and tow sides post the superpower reflecting film of U.S. 3M, promptly red and white, played warning function effectively.
