Description

A kind of LED intelligent street lamp control system and method thereof
Technical field
The present invention relates to the control field of LED street lamp, relate in particular to a kind of intelligence control system and method thereof of LED street lamp.
Background technology
Development along with society; one of oneself problem through becoming global concern the most of energy problem; energy crisis is own through becoming the main crisis that the whole mankind faces; particularly the electric power energy of China seems that in recent years ten minutes is critical; power tense hampers our daily production, life, even badly influences the progress of Chinese economic development and social civilization.And in the whole electricity consumption of China, electric consumption on lighting occupies very big ratio again.City street lamp is part important in the modern urban construction, and it serves traffic safety and people's production, living words, has beautified the city appearance, plays a part very important for creating good investment environment.The lighting quality that meets visual performance be ensure traffic safety, social security, people is engaged in and produces and conditio sune qua non such as recreation.Along with China's rapid economy development, the quantity of illuminating street lamp is more and more, and its power consumption accounts for the ratio of total electricity consumption in city also in continuous increase.Show that according to statistics China's annual consumption aspect street lighting surpasses 1,000 hundred million yuan the electricity charge, its development speed is very surprising.At city lighting, beautify under the trend of spring tide, our electric power resource is also being engulfed in the landscape light in city power consumption.And electricity power enterprise's investment and construction need long cycle, and economic development fast needs more more sufficient supplies of electric power and consumption, and is full of contradictions between the supply and demand of electric power.The supply of electric power breach is difficult in a short time to be alleviated, and development is laid equal stress on saving, and oneself is through becoming the inevitable choice of economic construction.At this moment, lighting industry economize on electricity also becomes our inevitable choice.
The light source of street lighting use at present mainly contains two kinds: the one, and traditional high-pressure sodium lamp, the one, the energy-saving LED road lamp that country relatively advocates, usage quantity is seldom.LED (Light Emitting Diode, light-emitting diode), have numerous advantages such as volume is little, little power consumption, the life-span is long, reliability is high, response speed is fast, driving voltage is low, just will progressively replace traditional lighting technology such as incandescent lamp and fluorescent lamp, be applied to fields such as major urban arterial highway, city subsidiary road, industrial park road, urban and suburban roads.
Energy-conservation, be the synonym of LED street lamp efficiently, National Development and Reform Committee proposes, and progressively eliminate incandescent lamp in 5 years, development LED green illumination.Nanjing in 2010 once pilot all make the street lamp on the road into the LED electricity-saving lamp, but try out more than a year, effect is the ideal of expection not but.In August, 2010, the LED lamp all is replaced by at Nanjing road lamp management place extensive pilot high-pressure sodium lamp that the both sides, road are liberated in Nanjing first.On the road of 3 kilometers of liberation road total lengths, installed 170 in LED street lamp, but pilot is got off more than a year, effect is but also not as people's will.According to default useful life, LED joint street lamp at least can be with more than 5 years, but in fact less than in the time in 2 years, and the driver of liberating all LED street lamps of curb line is maintain and replace all.Poor stability, price is expensive, later period maintenance expense height.
This shows, regulate the condition of work of LED street lamp, is unusual important problem to improve its useful life.
The intelligent wireless LED street lamp control system that proposes in the prior art, it comprises road lamp management centring system and Zigbee wireless sensing control system; Each LED street lamp is equipped with wireless road lamp intelligent controller in the Zigbee wireless sensing control system, carry out networking by Zigbee node ad-hoc network between wireless road lamp intelligent controller and the wireless road lamp intelligent controller, each wireless road lamp intelligent controller has a network address unique on network, and wireless road lamp intelligent controller adds network automatically in the back that powers on; The road lamp management centring system comprises monitoring PC and server, and the road lamp management centring system is connected with wireless road lamp intelligent controller network in the Zigbee wireless sensing control system by public network; Long-distance intelligent control by to street lamp realizes the illumination as required of road, saves the energy; By the collection to street lamp information, can monitor the operating state of street lamp in real time simultaneously, and the fault of street lamp is detected positioning analysis.
But in this implementation, the intelligent wireless controller on every LED street lamp is only realized single networking function, and information is uploaded to administrative center by network, self does not have the analysis and judgement function, to the control of the street lamp network that places one's entire reliance upon.When breaking down, network can not promptly and accurately control street lamp.
Another the high-power LED street lamp intelligent management control device that proposes in the prior art, it includes the control device box body, offer primary input port and the main output port that is used for being connected high-power LED street lamp for the civil power input on the described control device box body respectively, be characterized in: be connected with driver module on the input port, the output of driver module connects main output.The primary input end of driver module is connected with the intelligent switch control module.Be connected with time control module, induction control module, long-distance intelligent control module on the control end of intelligent switch control module respectively.Thus, the basis of controlling at the switch that routinizes of road lamp power supply increases intelligent switch control, reduces energy waste under the situation that does not influence use to greatest extent.Simultaneously, can allow high-power LED street lamp carry out best illumination according to the actual state of road environment.
But though this implementation has all kinds of control modules, the basis of controlling at the switch that routinizes of road lamp power supply has increased intelligent switch control, has reduced the waste of the energy.But do not consider the life curve formula of LED street lamp, the LED street lamp is worked long hours under big electric current and high heat, perhaps carry out light on and off control frequently, these all can seriously reduce the useful life of LED.Therefore this scheme can not be taken into account when reaching saves energy and prolong the street lamp purpose in useful life.
Though LED is energy-conservation, but it is the same with general incandescent light fitting, part energy is converted in the process of light in addition, and part energy changes into heat, especially LED is the point-like illuminating source, its heat that produces also concentrates in the minimum zone, if the heat that produces can't in time distribute, the junction temperature of PE knot will raise, wearing out of speed-up chip and potting resin also may cause solder joint to melt, and makes chip failure, and then directly influence useful life and the luminous performance of LED, especially great power LED, its caloric value is bigger, requires higher to heat dissipation technology.
Though a lot of LED products indicate that luminescent lifetime is more than 100,000 hours, but in present practical application, do not seem the so long life-span is arranged, reason is exactly that LED exists the light decay problem, in case the LED luminosity drops to below 30% of original luminance, just thinks that it is unavailable.The reason that causes the LED light decay mainly contains: a. temperature is too high to be caused.The light decay of LED street lamp is relevant with its junction temperature, and so-called junction temperature is exactly the temperature of semiconductor PN, the more high light decay that more early occurs of junction temperature, and just the life-span is more short.If from the LED street lamp life curve formula of certain producer as can be seen, junction temperature is 105 degree, and brightness is down to life-span of 70% and is had only more than 10,000 hour, 95 degree just have 20,000 hours, and junction temperature is reduced to 75 degree, and the life-span just has 50,000 hours, and 65 more can extend to 90,000 hours when spending.To reduce junction temperature exactly so prolong the key in street lamp life-span.The light of b.LED chip itself subtracts the light decay that causes with fluorescent material.Most of White LED street lamps are obtained by blue led irradiation yellow fluorescent powder.Cause that the main cause that LED street lamp high-power lamp pearly-lustre declines has two, one is the light decay of blue LED lamp pearl itself, and the light decay of blue LED lamp pearl wants fast more than the light decay of ruddiness, gold-tinted, green light LED lamp pearl.Also having one is the light decay of fluorescent material, and fluorescent material decay at high temperature is also very serious.C. the light decay that insulating cement, fluorescence glue cause in encapsulating.LED high temperature can cause that the performance of insulating cement and fluorescence glue reduces, thereby influences the luminous flux of light fixture output.The d.LED support is to the influence of light decay, and led support has copper stent and retort stand, and the thermal conductivity of copper and iron is different, and the copper good heat conductivity can be lowered the temperature to light fixture faster, and is less to the influence of light decay.
From top analysis as can be seen, under the situation that the street lamp material is determined, influencing topmost factor of LED street lamp life-span is the working temperature of street lamp, and the working temperature of street lamp and street lamp operating time, the electric current that applies voltage thereon and the street lamp of flowing through are closely bound up.
