Abstract

The invention discloses a metering support method of a measurement software module of a virtual instrument, comprising the steps: inserting an external interface device, and loading the measurement software module of the virtual instrument; reading an integrity check code of the external interface device, comparing the check code with a check code of the measurement software module, and judging the integrity of a software; acquiring the user certificate of the measurement software module, reading traceable digital certificate of the external interface device and a user authority list, and authenticating the identity of a user; and prompting to upgrade the software. The method can greatly inhibit illegal replacement, alteration and circumvention for the measurement software module of the virtual instrument, avoid the unauthorized change being easily carried out on metering parameters, obviously improve the integrity, the reliability and the safety of the measurement software of the virtual instrument, thus being capable of solving the metering problems of an existing virtual instrument and a software thereof, and finally leading the measurement of the virtual instrument to be normalized.

Description

technical field [0001] The invention relates to a measurement support method of a virtual instrument measurement software module, which is applied in the field of virtual instrument measurement. 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 evaluation of measurement and control instruments, covering virtual However, there are still few researches on integrity protection technology and effectiveness evaluation for virtual instrument applic...
