Utility model content
The purpose of this utility model is to provide a kind of civilian power supply product detecting instrument, can allow consumer very simply use this instrument to detect the power source products such as the portable power source, charger, battery of mobile phone of purchase, thereby can demonstrate very intuitively the quality of product.
For achieving the above object, the utility model provides following technical scheme:
A kind of civilian power supply product detecting instrument, comprise MCU processing module, the input end of described MCU processing module connects respectively button, inner adjustable constant-flow load, and at least one Universal USB input interface for being connected with tested power supply/charger, the output terminal connecting fluid crystal display screen of described MCU processing module.
As further program of the utility model: the input end of described MCU processing module also connects at least one Universal USB output interface for external load.
Existing detecting instrument be all to adopt special connecting line to connect with being connected of test product, compared with prior art, the beneficial effects of the utility model are: the utility model uses at present the most popular general USB connecting line on the market, to facilitate ordinary consumer to use; The utility model is also in integrated inner adjustable constant-flow load, and user can select directly to use inner adjustable constant-flow load to test or external load test.Use inner adjustable constant-flow load directly to test the worry of having saved terminal block, operate easier.
Brief description of the drawings
Fig. 1 is the structured flowchart of civilian power supply product detecting instrument.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of civilian power supply product detecting instrument, comprise MCU processing module, the input end of described MCU processing module connects respectively button, inner adjustable constant-flow load, and at least one Universal USB input interface for being connected with tested power supply/charger, the output terminal connecting fluid crystal display screen of described MCU processing module.
As further program of the utility model: the input end of described MCU processing module also connects at least one Universal USB output interface for external load.
The using method of function to the each module of the utility model, and instrument below describes in detail:
One, the content that LCDs shows comprises: the nominal output voltage of test product, nominal output current, the nominal capacity of the charging energy-storing class power supply products such as portable power source, battery of mobile phone.The operating voltage of test product, working current, actual discharge capacity (mAh), actual discharge energy (mWh), test duration shows, test product type shows, conversion efficiency demonstration, show with the product scoring mark drawing according to professional algorithm measurement, displaying contents can switch by button.
Two, this instrument has more than one conventional USB input interface and more than one USB output interface at least, the output port of the input interface of instrument access power source products, and the output interface of instrument can connect mobile phone, connect the load that load or instrument carry.By supply voltage and the electric current of detecting instrument input port, then after professional algorithm process, can analyze the quality of detected product.
Three, user can be by parameters such as the nominal voltage of key-press input test product, nominal current, nominal capacitys, test product is accessed to the input interface of instrument, output interface can connect external standard termination or directly use instrument internal load, and connected mode is all to adopt the most frequently used USB interface in life to connect.And do not need the special professional connecting line of buying.
Four, the detection method of portable power source, battery of mobile phone
First portable power source needs being detected, battery of mobile phone is full of electricity, then connects portable power source or battery of mobile phone with usb data line, selects portable power source/battery of mobile phone detection with button, then inputs the nominal voltage of portable power source or battery of mobile phone, nominal current, (default parameters is the parameters such as nominal capacity: nominal voltage 5.0V, nominal current 0.5A, nominal capacity 5000mAh), press beginning key, instrument is according to the portable power source setting, battery of mobile phone trace routine starts the no-load voltage of automatic testing product, no-load current, underloading voltage, underloading electric current, middle live is pressed, middle live stream, heavy duty voltage, heavy duty electric current, short-circuit protection, the projects such as overcurrent protection, and be recorded in the memory element of instrument internal, and then with constant-current discharge (constant-current discharge electric current can be adjusted with button as required in test process), detect virtual voltage and the actual current of test product, record discharge time, and the electric current and voltage data of sampling are stored in internal circuit, treat portable power source, after the complete discharge off of battery of mobile phone, automatically stop detecting hummer prompting, the flicker of LED lamp.Instrument by storage data analysis comparison: average voltage, average current, output ripple, actual discharge capacity, no-load voltage, no-load current, underloading voltage, underloading electric current, heavily loaded voltage, heavily loaded electric current, short-circuit protection, overcurrent protection.After analyzing relatively, go out the score of this product according to the different weight calculation of each test item.
