An Enhanced Virtual Instrument Measurement Software Metrology Support Method and Device

Abstract

The invention discloses a reinforced virtual instrument measuring software metrology support method and a reinforced virtual instrument measuring software metrology support device. The device comprises an outer shell and an inner circuit module, wherein the inner circuit module comprises an encryption and decryption module, a flash memory module, an RAM (random-access memory) module, a USB (universal serial bus) interface module, a serial port module and a display module, which are respectively connected with an MCU (microprogrammed control unit) module, and a 3G mobile communication module connected to the serial port module. The device effectively monitors measuring software of a virtual instrument in an unavoidable way, executes work such as user identity authentication, measuring software protection, calibration parameter protection and operation log record, transmits the working condition of the virtual instrument to a background monitoring center in real time, ensures that the tested measuring software always runs in the virtual instrument and realizes a measuring function in an expected manner, and guarantees the accuracy and the reliability of the measuring process of the virtual instrument.

Description

technical field [0001] The invention relates to a measurement support method and device for an enhanced virtual instrument measurement software that can be used together with a virtual instrument, and belongs to the field of virtual instruments and measurement. Background technique [0002] The virtual instrument uses a general-purpose computer or an embedded computer as a computing platform, uses modular hardware as an acquisition device, and uses software to realize flexible and powerful measurement functions. It has flexible functions, small size, short development cycle and low development cost, and has been widely used in the fields of metering, measurement and control. [0003] When virtual instruments are used, the underlying software itself is inherently vulnerable. When virtual instruments are used in trade settlement, security protection, environmental monitoring, statutory evaluation, fair calculation, etc., they are prone to illegal tampering with software, measu...

Problems solved by technology

Although NI and others have carried out strict tests and quality checks on the measurement controls and components released by themselves and third parties, there are currently no strict specifications for the construction of virtual instruments in different ways and technologies. The research on the operational method of evaluation has not yet been paid attention to by people. At the same time, the virtual instrument software system used in distribution is usually in a black box, and it is difficult to effectively evaluate its reliability.
