Solar street lamps to charge and discharge monitoring system solar energy lamp manufacturer

As is known to all, solar street light project is the representative of the national energy conservation and emissions reduction engineering project. On the light emitting component, LED itself characteristics have reached very good energy-saving effect, but the power energy has been the major manufacturers to ignore. So energy-saving power to buy



it is well known that the solar street light project is the representative of the national energy conservation and emissions reduction engineering project. On the light emitting component, LED itself characteristics have reached very good energy-saving effect, but the power energy has been the major manufacturers to ignore. So energy-saving power supply, no doubt will be street lamp power supply is the most important parts in the future. CLP huaxing with focus on power supply for many years, strive to improve the power supply quality and efficiency. LED power supply products which conversion efficiency is as high as 90% above, some products even as high as 95%, meet the requirements of all applications for high efficiency. Below to introduce solar street light for you

solar street light monitoring system is mainly composed of charging and discharging solar photovoltaic components, battery, charge and discharge controller, four major part lighting lamps and lanterns. The bottleneck of popularized solar street light is not technical problem, but the cost problem. Should on the basis of cost reduction, improve system stability and maximum effectiveness, to reasonable collocation solar cell output power and load power and battery capacity. Therefore, only from the theoretical calculation is not enough. Because the sun light 6 m street lamp price rapidly changing and charging current and discharge current are in flux, the theoretical calculation will bring bigger error. Only by adopting automatic monitoring to charge and discharge flow to accurately determine the cell in different seasons and different position of the maximum power output. To determine the battery and load is reliable.

    Using conditioning circuit of photovoltaic solar street lamps of output current and discharge current of battery and battery charging and discharging voltage of a certain frequency of data sampling, by the USB data acquisition module will collect data into the computer. On the LabVIEW software platform for timing display and statistical analysis.

battery output signals is a kind of floating. Solar street lamps use difference measurement methods will minimize to the influence of the circuit under test, at the same time also can reduce the measuring error. In this circuit, integrated operational amplifier with high accuracy, low drift is differential amplifier ICL7650 make string into differential signals over charge and discharge circuit of precise small resistance as a current detecting signal. Will be charged to the accumulator large resistor voltage divider for small signal as a voltage signal. To eliminate interference, using two equivalent resistance meet in between the two input terminal of the differential amplifier and signal ground. Gave away two differential amplifier output signal USB acquisition module of two input channels to complete the signal disposal and collection.
