Description
Technical field
The utility model provides a kind of electronic load device, particularly provides a kind of DC/AC electronic load device with oscillography function.
Background technology
Electronic load device conventional on the market generally can only by the data of display unit numeral display electric current and voltage, simultaneously, also there are some electronic load devices to be equipped with I_monitor port and can measure for user the approach that electric current provides external connected electronic equipment comparatively easy, as user carries out measurement display waveform by the oscillograph of external dedicated to the output signal of I_monitor port, but, this electronic load device exists can not facilitate user's oscilloscopic waveform detection to measured signal, and corresponding add external oscillometric device purchase cost and the problem easily disturbed of outer signal.
Utility model content
The purpose of this utility model is to provide a kind of DC/AC electronic load device with oscillography function, solve ordinary electronic load device and can not facilitate the problem that user's oscilloscopic waveform to measured signal detects and external equipment input is easily disturbed, and also solve the problem of outsourcing oscillometric device corresponding increase oscillometric device purchase cost.
To achieve these goals, the technical solution of the utility model is a kind of DC/AC electronic load device with oscillography function, display waveform is carried out to inputing or outputing signal by self oscillography function, comprise current sample module, voltage sample module, data processing unit, display unit and power cell, also comprise Oscillographic Signal processing module and oscillography display unit, be provided with Oscillographic Signal processing module in data processing unit, Oscillographic Signal processing module signal is delivered to oscillography display unit and is carried out waveform display.
The display screen of oscillography display unit and display unit is wholely set.
Display screen adopts the LCD display of 6-8 cun.
The utility model carries out corresponding extraction by digital signal processing unit and Oscillographic Signal processing module to the data after quantification to block scheduling algorithm thus the key signal that can fully reduce in waveform, final normalization data be sent to integration display large scale display screen, thus can directly user interface observe band year time voltage and current waveform and power waveform.
The beneficial effects of the utility model to facilitate user without the need to clearly understanding the instantaneous state of load and measured object thereof when other instruments and connection, for user provides a large amount of, abundant, data and waveform intuitively.
Accompanying drawing explanation
Fig. 1 is system architecture schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model embodiment.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment as depicted in figs. 1 and 2, the present embodiment provides a kind of DC/AC electronic load device with oscillography function, display waveform is carried out to inputing or outputing signal by self oscillography function, comprise the oscillography display unit of current sample module, voltage sample module, data processing unit, display unit, power cell, Oscillographic Signal processing module and 7 cun, the display screen of oscillography display unit and display unit is wholely set.
Be provided with Oscillographic Signal processing module in data processing unit, Oscillographic Signal processing module signal is delivered to oscillography display unit and is carried out waveform display.
DC/AC electronic load comprises sampling unit, and this sampling unit is used for sampling to the electric current inputted and voltage by current sample module and voltage sample module; Data processing unit, the sampled data receiving sampling unit carries out processing and produces the analog control signal for controlling power cell, and wherein, this data processing unit also comprises the funtion part for Oscillographic Signal processing module; Display unit and oscillography display unit can show through the data of data processing, current waveform, voltage waveform and power waveform etc.; Power cell, can be connected to outside determinand, and when determinand is supply unit, this power cell consumed power is drawn supply unit and carried.
