1. The system hardware design
Control 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.

Photosensitive 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.

Intelligent road lighting system can according to different area Domain of different functional requirements, at different times and different every day Natural light or under different traffic flow conditions, the press According to a specific setting, realize dynamic wisdom of road lighting Can management, namely the TPO management (TIME/PLACE, TIME Location/OCCASION occasions). 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 actionStreet 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.
1.1 hardware design
System 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.
