The sun light pole lights can offer the charge and discharge monitoring system

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 beyond



it is well known that 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. 】 Project is the representative of the national energy conservation and emissions reduction project engineering. 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 beyond

dispute 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

all the applications to the requirement of 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' This controller is intelligent to adjust the working voltage of solar panels, always work in V - making solar panels A characteristic curve of maximum power point. 】 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 of solar street light power output of the battery and battery capacity Battery in the prescribed conditions ( Including the intensity of discharge termination voltage, discharge current and discharge) Sent out how much electricity or discharge duration called battery capacity, unit or a. a. h min. 】 And the load power. Therefore, only from the theoretical calculation is not enough. Because the sun light strong rapidly changing and charging current and discharge current Discharge current is on load release the stored energy battery when the formation of the current. 】

are constantly changing, 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 the modulation circuit of photovoltaic cells output current and discharge current of battery and battery charging and discharging work voltage in a certain frequency data collect solar energy lamp manufacturers, by USB' USB, which is English the Universal Serial Bus ( Universal serial bus) Abbreviations, is a foreign bus standard, used in standard computer connections and communications with external devices. 】 Data acquisition module' Data acquisition is the bridge of a computer connected to the external physical world. 】 To collect data into the computer. In LabVIEW 【 LabVIEW is a kind of program development environment, by the U. S. national instrument ( 倪) Company research and development, similar to C and BASIC development environment, but the LabVIEW and other computer language is a significant difference: the other computer language is based on text language code, and the use of LabVIEW is a graphical editing language G program, the program is in the form of block diagram. 】
