Embodiment
Below in conjunction with accompanying drawing the present invention is described further:
As depicted in figs. 1 and 2, multi-functional electrician's experimental box shell 1 of the present invention is a body structure, and casing adopts transparent organic glass 2 as surface encapsulation.Shell 1 is embedded in a control panel (not shown); Control panel is provided with charge/discharge module, civil power AM access module, voltage/current sampling module, inverter, driving circuit, controller, daylight lamp load and display; Solar simulator, solar panel and accumulator that said shell is connected with control panel outward in addition, wherein solar simulator and solar panel are an integral body.Wherein the output terminal of solar panel links to each other with the input end of controller; The input end of voltage/current sampling module links to each other with the output port of controller; The input port of display links to each other with the output port of voltage/current sampling module; The input port of driving circuit links to each other with the output port of controller, and the input port of inverter links to each other with the output port of driving circuit, and the output of inverter links to each other with daylight lamp; The output port of controller links to each other with the input port of charge, and the input port of accumulator links to each other with the output port of charge.
Elder generation's energized during the test beginning, the bulb in the solar simulator begins luminous, regulates the bulb angle as required, and light irradiance reaches the certain standard value, and controller triggers electronic load scans solar panel with the mode of voltage I-V characteristic.Electronic load is accomplished the time of scanning solar panel I-V characteristic; One section metastable interval of irradiance matches in the pulsed light that must be sent with solar simulator; Meanwhile; The voltage/current sampling module to gather respectively the solar panel two ends voltage and with the output current of solar panel, when controller accomplish at the appointed time with voltage system from I-V characteristic short-circuit end after the open end been scanned, the total data finishing collecting; This moment, controller began according to fixing rule; The light irradiance that the output current and the voltage of measured solar panel is normalized to standard gets on, and controller shows through the electric current revised and voltage data and with these data storage through display, thereby has accomplished the test of I-V characteristic.
Multi-functional electrician's experimental box of the present invention adopts hybrid power supply circuit solar powered and mains-supplied; When the output current of solar panel when the voltage/current detection module detects output current greater than the setting value of electric current operate as normal, controller control charge/discharge module is to charge in batteries, when the light of solar simulator dies down; Controller detect light a little less than; The output electric energy can not satisfy the work of daylight lamp, detects the voltage at accumulator two ends again, if when the voltage of accumulator is between the operate as normal setting value; Give the daylight lamp electric through charge/discharge module controls accumulator, stop simultaneously to charge in batteries; If controller detects the voltage of accumulator and is lower than normal working voltage setting value following in limited time this moment, solar power supply circuit quit work, controller inserts civil power through civil power AM access module, for experimental box provides power supply.
The present invention adopts visualization window; Solar panel, civil power provide the multifunctional laboratory box of power supply jointly; Satisfy the experiment demand of traditional specialty and emerging specialty, satisfied the requirement of managing real Integrated Teaching, improved students'ability for practice; Excited Students'learning enthusiasm, the modularization of experimental box is formed maintenance and the maintenance of also being convenient to laboratory worker simultaneously.
