Street lamp lighting factory solar street lamp hardware technology

Solar street lamp USES AT89C52 single chip microcomputer as the control yuan, SCM accept photoelectric sensor signal after A/D conversion, the sunlight is strong at this time compared with minimum system design tracking threshold, when less than the threshold, chasing devices remain in situ, when the sun



the solar street lamps Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 Using AT89C52 【 AT89C52 is a low voltage, high performance CMOS 8-bit microcontroller, containing 8 k bytes of the tablets can be repeatedly wipe Flash read-only program storage data and 256 bytes of random access memory ( RAM) , the device adopts high density of ATMEL company, nonvolatile storage technology production, MCS - compatibility standards 51 instruction system, built-in general 8-bit CPU and Flash memory cell, AT89C52 single chip microcomputer has been widely used in the electronics industry. 】 Single-chip microcomputer as the control yuan, SCM accept photoelectric sensor signal after A/D conversion, the sunlight is strong at this time compared with minimum system design tracking threshold, when less than the threshold, chasing devices remain in situ, when the sunlight intensity is higher than the threshold, microcontroller start dealing with four quadrant photoelectric sensor signal, judge the sun position, the whole day start operation system, adjust the solar panels ( Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 The location of the. At the time of night. Sunlight light in less than a certain threshold, the photoelectric sensor output signal is weak, even no, then determine whether the lights in the work time, pyroelectric infrared sensor 【 Pyroelectric infrared sensor is introduced in the structure field effect tube, its aim is to complete the impedance transformation. 】 Began operating, pedestrian detection lit LED points. 1 the design of the position tracking system, solar street lamp solar position tracking device with the method of apparent sun tracking combined with photoelectric tracking, the system by the control unit processing through the AD conversion 【 The AD conversion is the analog-to-digital conversion. 】 After sun light intensity signal and photoelectric sensor setting threshold to compare with the processor, judge whether the weather is suitable for tracking the sun at the moment, if the light is suitable for the A/D converter ( A/D converter is AD converter, usually refers to an analog signal into digital signal of electronic components. 】 With signal processor transformation and deal with four quadrant photoelectric sensor, signal control, control of step motor' Stepper motor is the electrical pulse signal into angular displacement or linear displacement of open loop control motor, is a modern digital process, the main components of control system, has extensive application. 】 Operation, adjust the solar panels of the main optical axis 【 Parallel to the main shaft of light through the lens to the intersection point, after the intersection point is called the focus. 】 To make it with the sun's rays parallel solar panels in the plane perpendicular to the sun's rays.
