Embodiment 1

[0032] Android smartphone application software APP development uses Java as the development language, uses the open source IDE Eclipse as the development environment, uses Android SDK, Java development kit JDK, and development plug-in ADT for software development and debugging. The Android smartphone application software flow chart that the present invention develops is as Figure 4 shown.

[0033] When the smart phone with the application software installed is within the signal coverage of the wireless data acquisition device, run the application software, find the WI-FI communication unit in the wireless data acquisition device by searching, and perform a wireless connection, After the connection is successful, the functions of data collection, processing and graphic display are realized, and the interface displayed on the screen of the mobile phone is as follows: Figure 5 shown.

Embodiment 2

[0035] The application software on the computer is written using the graphical programming language LabVIEW, and the communication function with the WI-FI module is mainly realized through the TCP function and VI that comes with LabVIEW, such as Figure 6 As shown, add a "Open TCP Connection" function in the program block diagram, and set the IP address and port number (the settings here are consistent with those of the WI-FI module). The virtual oscilloscope panel designed with LabVIEW such as Figure 7 shown. After the software design is completed, it is installed on a computer with a mobile network card.

[0036] The computer with the mobile network card searches for the WI-FI signal sent by the wireless data acquisition device, and runs the installed application software at the same time. Function instructions, select the data acquisition channel, click the "acquisition" button, set the horizontal adjustment, vertical adjustment, scanning cycle and other parameters, and ...

Abstract

The invention discloses a wireless virtual oscilloscope realization system which comprises a wireless data collection device, mobile terminals and application software. The wireless data collection device is composed of a data collection module, a WI-FI communication module and a power source module, the mobile terminals are smart phones, PADs and computers with wireless network cards and are in wireless connection with the wireless data collection module in a point-to-point manner to realize bidirectional data communication, and collected waveform data are transmitted to the mobile terminals in a wireless mode. The application software installed in the mobile terminals processes, analyzes and performs waveform display on the waveform data. A method and system using a virtual instrument to remotely test time-domain signal waveform on the basis of wireless transmission technology is provided.

Description

technical field [0001] The invention belongs to the technical field of time-domain signal virtual testing, in particular to a wireless virtual oscilloscope realization system. Background technique [0002] The virtual instrument breaks through the characteristics of the traditional instrument. The data analysis function and display function of the traditional instrument are realized by the hardware, which is completed by a powerful computer, and the corresponding I / O interface equipment is configured for data collection, and then different test programs are compiled. Functional software can analyze, process and display the acquired signal data to form a complete test system with data processing function and friendly man-machine interface. [0003] Digital oscilloscope is a general-purpose desktop instrument often used in scientific research and laboratories. At present, this type of instrument is complicated to process and expensive. With the virtual instrument technology,...
