The utility model discloses a power supply test system of an automobile electronic product. The power supply test system of the automobile electronic product is characterized in that the power supply test system of the automobile electronic product comprises a computer, a function signal generator and a waveform amplifier; the computer is connected with the function signal generator through a communication interface and controls the work of the function signal generator; the function signal generator receives data and signals from the computer and transmits the data and the signals to the waveform amplifier which is connected with the function signal generator; and the waveform amplifier is connected with the function signal generator and a tested product respectively to receive the signals output by the function signal generator and to send signals to the tested product. Compared with the prior art, the power supply test system of the automobile electronic product has the advantages that with the system, automobile ignition voltage drop and other power supply changes can be accurately played back; and by using a simulation mode, vehicle damage and oil consumption are reduced, and the test cost is saved.
Description
Technical field
The utility model relates to the power supply test field, relate in particular to a kind ofly can extract the mains voltage waveform of automobile electronics, the test macro of conversion and playback.
Background technology
At present, the auto industry develop rapidly, many electricity or full electric car have become a kind of development trend, the quality of automobile power system performance has very important effect to the quality of automotive performance, vehicle power management or test macro are responsible for automobile power system is tested and monitored, and send the work state information of electric power system and the work state information of vehicle power management system itself to truck-mounted computer, on the other hand, vehicle entertainment system is as the part of the electronic system on the automobile, need to bear the interference of car load power environment, particularly automobile falls at the voltage that ignition point produces.Therefore, to the test job of power-supply system, just seem particularly important.
At present in the test of vehicle electronics product, the simulation igniting waits the test of power management aspect to adopt the analog waveform that is made of basic waveform (straight line, sine wave, triangular wave) to test and can only simulate theoretically, really the power supply change process of accurately playback real car.And if the test of igniting adopts real vehicle to carry out, ignition operation is larger to the infringement of vehicle frequently, and corresponding cost is also higher.
Summary of the invention
The shortcoming and defect that exists for solving above-mentioned prior art, the utility model provides a kind of and can extract the mains voltage waveform of automobile electronics, the test macro of conversion and playback.
The purpose of this utility model realizes by following proposal:
A kind of power detecting system of automobile electronics comprises computing machine, function signal generator and waveform amplifier; Described computing machine is by the connection of communication interface function signal generator and control its work, described function signal generator receives from data and the signal of computing machine and transfers to the waveform amplifier that is attached thereto, described waveform amplifier respectively function signal generator connects the signal of receiver function signal generator output, is connected with test product and signal is sent to test product.
The utility model has following advantage and beneficial effect with respect to prior art:
(1) by this system, the accurately power supply change such as playback automotive ignition pressure drop;
(2) use the mode of simulating, reduce to the infringement of vehicle and with oil, save testing cost.
Description of drawings
Fig. 1 is the system chart of the power detecting system of a kind of automobile electronics of the utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but embodiments of the present invention are not limited to this.
As shown in Figure 1, a kind of power detecting system of automobile electronics comprises computing machine, function signal generator and waveform amplifier; Described computing machine is by the connection of communication interface function signal generator and control its work, described function signal generator receives from data and the signal of computing machine and transfers to the waveform amplifier that is attached thereto, described waveform amplifier respectively function signal generator connects the signal of receiver function signal generator output, is connected with test product and signal is sent to test product.
At first, computing machine is opened the voltage oscillogram that the picture form is preserved, utilize algorithm to extract and convert to Wave data, then by communication interface data transmission is worked to signal generator and control signal generator, be given to test product after the voltage signal of signal generator output amplifies through the waveform amplifier and test.Wherein, the software processing procedure of computing machine is: open the waveform picture, picture choose a pixel that needs scope to be processed and waveform trace as a reference point after, the similarities and differences of the color of point by background in the contrast selection range and the color of reference point, extract waveform trace and select broad-brush central point as the data value of reality, and automatically calculate its corresponding magnitude of voltage.After finishing extraction, software is worked data transmission to signal generator and control signal generator by the PORT COM of computing machine and signal generator.
In a preferred embodiment, the WAVESURFER 42MXS-B oscillograph crawl form by LeCroy is the waveform picture of jpg, requires the picture can true reflected waveform ratio, and the color of waveform trace and background color have certain difference.Use on computers software, by the method for pixel color contrast, extract waveform trace and extract the central point of thick line waveform as actual voltage value by algorithm.By the parameter of setting, automatically calculate the actual value of voltage waveform, with form reservation or the storage of point.By the WF1974 signal generator of USB interface transmission NF, the control signal generator is tested.Because the voltage and the power that adopt NF WF1974 signal generator to support are all too little, need to amplify output signal, adopt the BP4620 power amplifier of NF that weak signal is amplified, voltage reaches as high as 115V, and the electric current maximum can reach 52A.Time precision is up to 10us.
Above-described embodiment only is the better embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other are any not to deviate from change, the modification done under Spirit Essence of the present utility model and the principle, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
