Abstract
The utility model discloses an impact peak value display instrument for an oscillometer. The display instrument comprises a singlechip connected with three movable registers, wherein two of the movable registers are connected with an upper-rank nixie tube and a lower-rank nixie tube respectively, and the third movable register is connected with an input keystroke. The singlechip is further connected with a USB chip and the USB chip is connected with a USB interface. By adopting the display instrument, the peak voltage in an impact test can be displayed conveniently, straightforwardly and accurately, not only the function of the oscillometer is expanded, but also the problem of reading the peak voltage in the impact measurement is solved.
Description
Technical field
The utility model relates to a kind of display instrument, and is especially a kind of by supporting with oscillograph, can substitute the oscillograph impact peak value display instrument of traditional impact peak value voltage table.
Background technology
When the surge voltage of high-potting is measured, generally adopt impact peak value voltage table or oscillograph to measure at present.The impact peak value voltage table can only obtain the crest voltage value, can not the observation experiment waveform, and be subject to the response characteristic of peak value meter, and the undesired signal in the impact experiment might be shown as false peaks, cause measuring error.Though oscillograph is powerful, the automatic peak value read functions that it possessed is that simple single-point peak value obtains, if undesired signal is arranged, also the undesired signal peak value may be shown as false peaks.And the peak-data of obtaining and the parameter of joining sensor outward will manually calculate, and real trial voltage peak value could be shown.Have only and manually read and artificial calculating just can be obtained real peak so oscillograph reads the impulse test voltage peak,, also have the error of artificial reading so it is both inconvenient directly perceived to read the surge voltage peak value with oscillograph.
The utility model content
The purpose of this utility model provides a kind of by supporting with oscillograph, can substitute the oscillograph impact peak value display instrument of traditional impact peak value voltage table.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of oscillograph impact peak value display instrument, it is characterized in that: comprise single-chip microcomputer, described single-chip microcomputer is connected with three mobile registers, wherein two row's of being connected with charactron and following row's charactrons respectively, another one is connected with the input button, described single-chip microcomputer also is connected with the USB chip, and this USB chip is connected with USB interface.
The beneficial effects of the utility model are, the supporting TDS1000/2000 series digit storage of this product dual channel oscilloscope, the convenient visual and accurate demonstration of impulse test crest voltage both can be expanded oscillographic function, solve the problem that the shock measurement crest voltage reads again.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
Embodiment
According to embodiment the utility model is described in further detail below.
In view of the traditional surge voltage measuring method and the deficiency of instrument, we have developed this cover instrument.A kind of oscillograph impact peak value display instrument, comprise single-chip microcomputer, described single-chip microcomputer is connected with three mobile registers, wherein two row's of being connected with charactron and following row's charactrons respectively, another one is connected with the input button, described single-chip microcomputer also is connected with the USB chip, and this USB chip is connected with USB interface.
The demonstration of oscillograph impact peak value display instrument crest voltage with read, be based on TDS1000/2000 series digit storage dual channel oscilloscope as analog signal processing, utilize the USB mechanics of communication that oscillographic test waveform data are sent to display instrument, by to the Wave data Treatment Analysis, the trial voltage impact peak value is directly shown then.The supporting TDS1000/2000 series digit storage of this product dual channel oscilloscope can both have been expanded oscillographic function with the convenient visual and accurate demonstration of impulse test crest voltage, had solved the problem that the shock measurement crest voltage reads again.
The demonstration of oscillograph impact peak value display instrument crest voltage and the realization of reading are to utilize the USB mechanics of communication that oscillographic test waveform data are sent to display instrument, by data processing, the trial voltage impact peak value are directly shown then.The principle of instrument as shown in Figure 1.
This instrument adopts the master control core of MEGA32 industry single-chip microcomputer as instrument, and the communication work of control instrument, test data computing, crest voltage show.
Utilize the special-purpose communication chip CH375 of USB to realize and oscillographic data communication that in this communication link, display instrument is as main frame, oscillograph is a slave.Here we have adopted the communications protocol of USB1.0.
Instrument adopts two 8 HC164 shift register, drives two 47 sections LED respectively and shows charactron, shows as instrument.When work, two 47 sections light-emitting diode displays show the crest voltage of two channel oscilloscopes respectively.When instrument parameter is set, last row's charactron display parameter title, following row's charactron display setting value.
HC164 interface and four free-standing keyboards have been formed the key input section of instrument, can realize setting the running parameter of instrument.The instrument parameter that can set comprises passage unlatching, polarity selection, multiplying power setting, mode of operation etc.
Instrument adopts and exchanges the power supply of 220v power supply, and the DC voltage that produces 5V by rectification satisfies each parts work.
