Description

Self-adapting intelligent solar traffic light
Technical field
The utility model belongs to Application of Solar Energy field, particularly relates to a kind of intelligent solar traffic lights.
Background technology
Solar electrical energy generation is to utilize the photovoltaic effect of interface luminous energy directly to be changed into a kind of technology of electric energy.Photovoltaic effect is called for short " photovoltaic effect ", refers to produce between different parts that illumination is combined inhomogeneos semiconductor or semiconductor and metal the phenomenon of potential difference (PD).First it is the process that is converted into electronics, luminous energy and is converted into electric flux by photon (light wave); Secondly be, to form voltage course.There is voltage, just as having built dam high, if be communicated with, will form the loop of electric current between the two.The advantage of photovoltaic generation is the less regional limits that is subject to because the sun is shining all over the earth, photovoltaic system also has advantages of noiseless, low pollution, without consume fuel and erect power transmission lines can generate electricity on the spot power supply and build the same period short.
Utilizing solar power system to carry out accumulation of energy charging to accumulator is common technology, traditional sun power is after luminous energy arrives the conversion of electric energy, charge to accumulator through controller for solar, or electric energy is through controller for solar and the backward AC load power supply of inverter, or solar panel is directly powered to DC load, after accumulator electric-quantity abundance, need only on the market at present user at the sun power using to charge in batteries and do not cut off charger input power, charger will charge to battery always, can shorten like this life-span of charger, increase the failure rate of charger, easily cause other dangerous accidents, while stopping sun power to charge in batteries, should first disconnect being connected between charge controller and solar panel, being connected between rear disconnection charge controller and accumulator, otherwise easily cause battery charger failure.In prior art, also there is the shortcoming of waste electric energy.
Simultaneously, once the voltage of solar panel is lower than battery tension, charging process will stop, until the power up of solar panel, in daily life, because illumination does not stop to change, therefore be also extremely unstable to the charging of accumulator, if too frequent to the charging of accumulator, easily reduce the life of storage battery, and greatly reduce charge efficiency.Due to above shortcoming, cause the accumulator of solar recharging can not be widely used in every field, limit scientific and technical progress.
Aspect raising solar energy utilization ratio, sun location tracking has been proved becomes Main Means.So-called sun location tracking, refers to the position angle of adjusting solar panel, makes its sensitive surface keep being all the time tending towards vertical relation with sunray, is similar to the principle of sunflower, and object is to allow effective sensitive surface collect more sun power.Receive flat board for same sun power, the sun power receiving in the time that it is vertical with solar radiation direction is roughly 3 times of the solar radiation energy receiving when it is fixed towards south.
Utilizing at present sun power to carry out in the systems such as photovoltaic generation, solar water, the installation direction of solar panel is to be generally fixed installation according to local situation at sunshine, therefore overwhelming majority time sunray is also not exclusively vertical with the phototropic face of solar panel, and utilization and the conversion ratio of sun power are lower.For improving the absorption conversion efficiency of solar panel, certain methods and technology are used to regulate solar panel, make sunray as far as possible vertical sand shooting to solar panel.Traditional method mostly is and records local running track from sun, then automatically carries out the adjustment of solar panel by the track of the sun according to the information of record.The cog belt driving group synchronous tracking sunlight automatically tracking device based on running track from sun to earth that the active solar energy tracing method that for example China Patent No. 200910100808.6 is announced and device and 200910086319.X announce, all to utilize the running orbit of time signal and the sun to follow the tracks of, the problem that these class methods exist has: the one, and the sun irradiation angle difference of various places, therefore different regions must be recorded different running track from sun information and be moved by different information, and workload is large; The 2nd, the information of record is many, computing more complicated; The 3rd, when overcast and rainy, sunray does not have obvious directive property, but electric system still power consumption carry out work.
