Virtual instrument measuring support storage device

Abstract

The invention discloses a virtual instrument measuring support storage device which is used together with detected virtual instrument software. The virtual instrument measuring support storage deviceis provided with a USB interface and comprises an external casing module, a casing internal control circuit module and a built-in file system, wherein the internal control circuit module comprises theUSB interface, a flash memory, an MCU and a buffer, the MCU implements the user identity authentication and the program data integrity verification and completes the address strobe and the digital-analog conversion, and a port of the MCU is connected with the USB interface, the flash memory, the buffer and an intelligent indicator lamp module; and the built-in file system comprises an integrity verification file, a log file, a user authority list, a measuring calibration parameter file and a traceable digital certificate. The invention has the advantages of high storage reliability, portablevolume and plug-and-play.

Description

technical field [0001] The present invention relates to a virtual instrument metering support storage device, in particular to a device used in the field of virtual instrument metering, which is used in conjunction with virtual instrument measurement software, has high reliability, is portable in size, and has a plug-and-play USB device. Virtual Instrumentation supports storage devices. Background technique [0002] With the development of computer hardware and software technology and the application of virtual instruments, extensive research has been carried out on virtual instrument technology in recent years. In the field of measurement and control, international metrology institutions such as OIML and WELMEC pay attention to software characteristics such as reliability and integrity protection of measurement and control instruments, and put forward suggestions based on software protection requirements, protection methods, reliability assurance and software quality evalua...

Problems solved by technology

In the field of measurement and control, international metrology institutions such as OIML and WELMEC pay attention to software characteristics such as reliability and integrity protection of measurement and control instruments, and put forward suggestions based on software protection requirements, protection methods, reliability assurance and software quality evaluation of measurement and control instruments, covering virtual instrument types, but there are few researches on integrity protection technology and effectiveness evaluation for virtual instrument applications

[0003] At the same time, identity authentication has been studied in depth in the field of information technology, and user identity authentication based on user passwords, digital certificates, biometrics, and even multi-factors has been proposed and implemented, but identity authentication combined with virtual instrument measurement and use of copyright has not yet been completed. attract attention

[0004] Although software quality is very critical to the correct and effective work of measurement and control instruments, there is no strict standard for constructing virtual instruments in different ways and technologies. Because software quality assurance is a systematic project, it involves software design, development, use, management, maintenance and Evaluation and other aspects, but the virtual instrument software system used in distribution is a black box, and it is difficult to evaluate its reliability

Although NI and others have carried out relatively strict testing and quality control on the measurement controls and components released by themselves and third parties, the research on the operational methods for the reliability assurance and evaluation of virtual instrument software has not yet received people's attention
