Abstract
The disclosed Internet storage oscilloscope is capable of measuring and displaying waveform of electric signal. Through wired or wireless link, WEB browser, searching engine of measuring probe, WEB server/ collection server of waveform of electric signal are connected to TCP/IP network each other. After receiving collection command sent from WEB browser, the measuring probe carries out data collection. Through TCP/IP network, the collected data are transmitted to allochthonic WEB browser. The WEB browser displays waveform of the electric signal in time domain and spectrogram.
Description
Affiliated technical field
The present invention relates to a kind ofly carry out the technical method that electric signal waveform is measured transmitting and displaying by the TCP/IP network, is the distributed storage oscilloscope that is used for electric signal measurement, belongs to measuring instrument.
Background technology
At present, the measuring probe of general-purpose oscilloscope and electric signal waveform display unit all are integrated in the middle of the same instrument.The virtual oscilloscope that exists on the market or the measuring probe of logic scope and electric signal waveform display unit still are integrated in the middle of the same instrument, and just its signal processing and demonstration utilize software to realize.But, when the waveform observer not at the scene of electric signal measurement point, or do not carry general-purpose oscilloscope, or will observe the electric signal waveform of a plurality of measurement points on the diverse geographic location simultaneously the time, general-purpose oscilloscope then can not play a role, as the electric signal measurement of following situation:
1. the different circuit module development group of company or scientific research institutions are positioned at the diverse location of the earth, need to observe the electric signal waveform of the other side's circuit module point between them sometimes.
2. the remote circuit MEASUREMENT TEACHING and the guidance of colleges and universities.
3. the long-range Bioelectrical Wave of hospital is measured.
4. some hazardous area of industrial circle is not suitable for artificial field observation electric signal waveform.
5. under situation about moving, carry out the measurement of certain fixing point electric signal waveform etc.
Summary of the invention
In order to overcome the shortcoming of general-purpose oscilloscope under the above-mentioned situation, the invention provides a kind of internet storage oscilloscope, this internet storage oscilloscope carries out data acquisition by measuring probe, carry out image data transmission by the TCP/IP network, the WEB browser by the strange land carries out time domain waveform and frequency spectrum shows.The WEB browser can search the IP address of specified point measuring probe by the measuring probe search engine.
The technical solution adopted for the present invention to solve the technical problems is: internet storage oscilloscope is formed by the individual measuring probe of 1 to n (n is a positive integer) that can separate on the geographical position, WEB browser, measuring probe search engine and with their interconnected TCP/IP networks.Wherein measuring probe is made up of WEB server, electric signal waveform acquisition server and A/D converter, and the WEB server both may reside in the measuring probe physically, also may reside in the measuring probe search engine.The TCP/IP network refers to utilize ICP/IP protocol to carry out the network that information transmits, and both can be the Internet in the global range, also can be LAN (local area network (LAN)), WLAN (wide area network), Intranet network or wireless network.The WEB browser refers to the WEB browser on any operating system platform.The WEB browser is a client, and measuring probe is a server.
Be connected in any WEB browser on the TCP/IP network and can search the IP address (IPV4 or IPV6) of the measuring probe m that will visit by the measuring probe search engine, the WEB browser loads the service routine menu that occurs behind this IP address based on WEB, the Man Machine Interface input data necessary acquisition parameter (as acquisition rate, sampling number or sampling time etc.) that operating personnel provide according to program.Carry out data necessary encryption, packing data after these acquisition parameters are identified, be transmitted to the electric signal waveform acquisition server that is arranged in measuring probe by the TCP/IP network then.Acquisition server carries out that data are unpacked, obtains relevant acquisition parameter behind the data decryption the acquisition parameter that receives, acquisition server sends instructions to the A/D converter measurement point is carried out the electrical waveform collection then, and the data of collection are temporarily stored in the data buffer zone of acquisition server; After collection was finished, acquisition server carried out data encryption, packing data with the data of gathering, and by the TCP/IP network ciphered data is sent to the WEB browser of far-end then; The WEB browser is temporary in the data of receiving in the local data buffer zone, is decrypted after Data Receiving finishes, and then carries out necessary signal processing, and the time domain electrical waveform and the spectrogram of synthetic acquired original point indicate time domain or frequency domain canonical parameter simultaneously at last.
The invention has the beneficial effects as follows, no matter when and where,, just can carry out long-range electric signal waveform and measure demonstration as long as can go up the Internet.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a network structure of the present invention.
1.WEB browser among the figure, 2. measuring probe search engine, 3.WEB server/electric signal waveform acquisition server, 4.A/D converter, 5. signal acquisition point, 6. measuring probe, 7.TCP/IP network, the 8. internetwork link of equipment and TCP/IP.The link here is meant wired or wireless link.Measuring probe is a kind of instruction from the WEB browser to be made an explanation, and the device that data after the back initiatively will be handled send the WEB browser to is gathered, handled to the signal of telecommunication of signal acquisition point.
Embodiment
In Fig. 1, WEB browser (1), measuring probe search engine (2), WEB server/electric signal waveform acquisition server (3) are interconnected by wired or wireless link (8) and TCP/IP network (7) respectively, A/D converter (4) links to each other with WEB server/electric signal waveform acquisition server (3), and A/D converter (4) also links to each other with signal acquisition point (5).WEB server/electric signal waveform acquisition server (3) and A/D converter (4) constitute measuring probe (6).
Claims (6)
- An electric signal waveform measure, storage, transmission and the internet storage oscilloscope that shows, will be not on the measuring probe in same geographical position and WEB browser logic, do not link up by the TCP/IP network, send the signal of telecommunication of measuring probe collection the WEB browser of strange land to, the WEB browser becomes time domain waveform and spectrogram to show the digital signal conversion of receiving.The TCP/IP network refers to the Internet net (the Internet), LAN (local area network (LAN)), WLAN (wide area network), Intranet network or wireless network.
- 2. according to claims 1 described internet storage oscilloscope, the signal of telecommunication utilizes the WEB browser to carry out the waveform demonstration.
- 3. according to claims 1 described internet storage oscilloscope, the hardware carrier of WEB browser is any hardware carrier that PC, notebook computer, portable terminal, GSM mobile handset, 3G mobile, PDA etc. can carry the WEB browser.
- 4. according to claims 1 described internet storage oscilloscope, each measuring probe can be gathered multiple signals.
- 5. according to claims 1 described internet storage oscilloscope, the IP address of the WEB server of each measuring probe can search by the measuring probe search engine.
