Intelligent road lighting Control system, through the comprehensive consideration and analysis and road Ming is closely related to the intensity of illumination time, road, environment and hand it in Scene control methods of factors such as flow rate, in the microcomputer According to the preset control strategy, the road lighting into action Street lamp intelligent management and control in different conditions normally In different states implement diversified road lighting scene, To improve the quality of lighting at the same time get the best section Can effect.1. The system hardware designControl circuit mainly to light, temperature signal acquisition, data computing and analysis, and control of street lamp driver circuit according to the results of the operation. Circuit must have MD conversion function, adopt STCl2C5608AD single chip microcomputer as control unit, the single-chip computer as a single clock cycle enhanced 8051 kernel microcontroller, it contains 8 KB FLASH program memory, eight road lO MD conversion interface, can meet the need of data acquisition. Light intensity, temperature sensor using photosensitive resistance and thermal resistance, respectively. Figure 1Figure 2Photosensitive resistor Rx and resistance R2 bleeder circuit, light intensity changes, microcontroller P1.7 pin input voltage changes, and P1.7 pin can be set up for MD conversion interface, set a threshold voltage for light intensity can distinguish between day and night. Thermal resistor Rx and R3 bleeder circuit, the temperature changes, P1.5 pin voltage change, the figure 1 watch NA L/D conversion control circuit green quality can calculate the actual environment temperature and time control to modify parameters. S1 for four dial the code switch, can be used to think.1.1 hardware designSystem hardware modules include: control module, mining Use 89 c51 to realize on STC; Sensor module, Using photosensitive resistance on the surrounding environment light Sample, using photosensitive diode on-off to street lamp equipment Obstacle detection; The clock module, using DS1302 clock chip Slice; Display module, which is made up of four LED digital tube, use To display the fault street lamp number; Sound and light alarm module, Implementation of malfunctioning of the street lamp light hint; Communication moduleBlocks, used to transmit commands from PC.1.2 module functionOn STC 89 c51 based on DS1302 clock chip Provide the clock signal, according to the following time implementation control Turn off the lights.(1) : winter time 18:00 lights at night, The next morning at 7:30 to turn off the lights.(2) age season time: the evening number is turn on the light, The next morning at 6:30 to turn off the lights.(3) in the summer time: 20:00 lights at night, The next morning at 5:30 to turn off the lights.Dynamically changes of this period of time, changes in the operation A machine to complete, through the communication module will hold instructions written to STC 89 c51 chip, then changed the point open to turn off the lights During work time.Photosensitive resistance, by appropriate wavelength of light , the current will along with the increase of light intensity, thus Realize the photoelectric conversion. To die by ADC0832 device Hold number converted to provide single-chip, STC 89 c51 according to The default program realize the electric lamp switch function. (1) automatic metering, during the day (or light) When lights go out, night (dark or light) street lights automatically Light up. (2) the sensitivity is adjustable, can adjust according to need Any work under the light. (3) to prevent the instant bright light interference, the AD hoc Delay off function (to strong light, the light switch When 30 seconds to shut down automatically).Photosensitive diode is to use silicon PN knot when the light is produced A photoelectric device, light current work in reverse bias Because of the pressure. During the day light or lamp light photosensitive 2 directly Diode reverse resistance decreases, and diode conduction; Light is very Hours photosensitive diode reverse resistance increases, the diode The check. Using photosensitive diode, detection of street lamp is night Normal work. When the photosensitive diode as shows that street lamp Equipment failure or theft, acousto-optic quote on STC 89 c51 started Alarm device, at the same time in four LED digital tube display the corresponding The street number.2.The system software design The software design of this system is divided into seven parts, mainly Including the LED digital tube display program design; Light to check the Test program design; Equipment fault detection program design; when Clock driver chip design; Open to turn off the lights program design; Communication program design; Audible and visual alarm program design, etc.Software includes: main program, system initialization, anti-fuzzy functions, A/D conversion subroutine, communication processing subroutine, keyboard processing subroutine, warp/weft clock computing functions, dial the code switch handle child, switch input processing function, the switch quantity output treatment function, display function. MCU software programming to CodeVisionAVR C compiler as a development platform, USES C written in a high-level language.3.TAGUSES the wireless transceiver module and single-chip integration design, can reduce the hardware cost of the system, convenient installation, easy maintenance. Adopt type a 15 STR micropower wireless digital module, high efficiency forward error correction channel coding technology, improves the data the abrupt interference and random interference resistance ability. Using high-speed microcontroller W7E58, improve the measurement precision of the liquid level, simplified the hardware structure of the system. The system not only for level measurement is a kind of safe and effective solutions, can be applied to other material level measurement under the bad environment.Street lamp lighting system is indispensable to the road traffic Facilities, design a kind of intelligent street light control system, right Increase induced by road, improve the driving safety at night And comfort, effectively prevent criminal activity, beautify the environment, Save power resources, has a certain practical significance and can be Development value.References 1, truth, science and technology. 8051 series single chip microcomputer C program design manual M.
