Diesel Engine Measurement and Control System Based on Virtual Instrument Technology [Copy link]

The diesel engine test instrument based on virtual instrument technology


has gone through three stages: analog instrument, digital instrument and intelligent instrument. The basic structure of analog instrument is
composed of various circuits composed of magnetic mechanical analog devices, with low accuracy, slow speed and poor adaptability; while digital instruments such as digital tachometers are mainly composed of digital devices,
which have greatly improved the test accuracy, speed and instrument life than analog instruments. With
the development of digital signal processing technology and large-scale development, intelligent instruments with microcomputers as the core have emerged, but because they exist in the form of functional simulation, they are not
active in development or application. In the late 1980s, the performance of microcomputers was greatly improved, and the successful application of general software development platforms for test analysis led to
the emergence of instruments. Using virtual instrument technology, users can customize the functions of instruments and create 32-bit compilers, thereby improving
the running speed of tasks such as assembly and testing.
