Embodiment Construction

[0036] In order to make the purpose, technical solution and purpose of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. The specific examples mentioned here are only for explaining the present invention, not limiting the present invention.

[0037] The soft panel involved in this embodiment includes a display interface and a control terminal interface. Functional modules include USB-OTG high-speed data transmission module; oscilloscope related data acquisition and processing module; signal generator related data acquisition and processing module; WIFI data access module. The flow chart of soft panel and function realization is as follows: figure 1 as shown,

[0038]According to the implementation method of the present invention, it can be seen that the function implementation of the portable instrument is divided into two different levels of hardware implementation according to the s...

Abstract

The present invention relates to the technical field of virtual instruments, and particularly to an Android based method for implementing a portable virtual instrument, comprising: using an Android device as a terminal to display a signal waveform and a soft interface that controls an output function of a peripheral circuit; with collaboration of an embedded peripheral STM32 and in combination with an internal ADC and an external high-speed ADC, implementing a signal acquisition hardware circuit and a signal generator hardware circuit at two levels, and transforming the Android device into a 60 MHz oscilloscope, a 200 MHz signal generator, and a + / -15V direct current (DC) power supply; and adding a WIFI module to store and access experimental data. According to the invention, with collaboration of the embedded peripheral, the portable Android device is used as a display and control terminal. The portable Android device is applicable to teaching, to some extent can replace a conventional instrument, and has high commercial value and high practical value.

Description

technical field [0001] The invention relates to the technical field of virtual instruments, in particular to an Android-based implementation method of a portable virtual instrument, which is suitable for industrial measurement, "pocket laboratory", home medical and health care instruments, and the like. Background technique [0002] Traditional instruments such as oscilloscopes and signal sources are too bulky to be moved to classrooms. Therefore, in colleges and universities, the basic courses of electronic circuits and experimental courses are often separated into two parts and taught separately, resulting in the separation of classroom and experiment. The emergence of this phenomenon will often aggravate the problems that college students at this stage place more emphasis on "theory" than "practice", "books" rather than "hands-on", and focus on single major learning and lack of combined learning of software and hardware. [0003] The concept of virtual instrument propose...
