Virtual instrument is one of them. Virtual instrument is a programmable instrument and instrument system based on general PC, which is a computer instrument system designed and defined by users, with virtual front panel and test function realized by test software on the hardware platform with general computer as the core. In virtual instruments, hardware is only to solve the input and output of signals, and software is the key of the whole instrument. Users can construct instruments with almost any function through software. Now virtual instrument has been widely used, and has become a hot technology in the field of testing technology at home and abroad. The instrumentation technology in different stages also belongs to the instrumentation with certain physical form, which mainly relies on its own hardware to realize its functions, that is, the instrumentation with physical and specific mixed proportional entities in the traditional concept. Its common feature is that it does not first introduce the background information: the physical instrument of polimotor 1 is separated from the material foundation, but also has shape specifications Common material characteristics such as difficult to change functional characteristics and material consumption resources

traditional intelligent instruments mainly use some computer technology in instrument technology, while virtual instruments emphasize the absorption of instrument technology in general computer technology. Due to the high development of microelectronics technology, computer technology, software technology, network technology and its application in measurement technology and instruments in the electronic industry, new testing theories, new testing methods, new testing fields for analytical columns and new instrument structures are constantly emerging, which has broken through the concept of traditional instruments in many aspects

as the core of virtual instrument, the software system has versatility, popularity, visibility, scalability and upgrading, and can bring great benefits to users. Therefore, it has an application prospect and market unmatched by traditional intelligent instruments

intelligent instrument is the combination of computer science, electronics, digital signal processing, artificial intelligence, VLSI and other emerging technologies with traditional instrument technology. With the development of ASIC, personal instrument and other related technologies, intelligent instruments will be more widely used. As the core component of intelligent instruments, single chip computer technology is the driving force to promote the development of intelligent instruments in the direction of miniaturization, multifunction and more flexibility. It can be expected that intelligent instruments with various functions will be widely used in all fields of society in the near future

virtual instrument is one of them. Virtual instrument is a programmable instrument and instrument system based on general PC, which is a computer instrument system designed and defined by users, with virtual front panel and test function realized by test software on the hardware platform with general computer as the core. In virtual instruments, hardware is only to solve the input and output of signals, and software is the key of the whole instrument. Users can construct instruments with almost any function through software. Now virtual instrument has been widely used, and has become a hot technology in the field of testing technology at home and abroad

the main functions of measuring instruments are composed of three parts: data acquisition, data analysis and data display. In virtual reality system, data analysis and display are completely completed by PC software. Therefore, as long as some additional data acquisition hardware is provided, it can form a measuring instrument with PC. This kind of measuring instrument based on PC is called virtual instrument. In virtual instruments, using the same hardware system, as long as different software programming is applied, measurement instruments with completely different functions can be obtained. It can be seen that software system is the core of virtual instrument, and software is instrument

with the further updating of PC, semiconductor and software functions, the function and performance of virtual instrument have been continuously improved. Now in many applications, it has become the main alternative to traditional instruments. The various advantages of virtual instrument allow users to safely abandon the old traditional measuring equipment and accept the updated computer-based virtual instrument system

due to the continuous improvement of the performance price ratio of computers, the price of virtual instruments is more popular. Users no longer have to be limited by the use restrictions and expensive prices of traditional instruments, which further reduces the use cost, system development cost and system maintenance cost. In addition, the new notebook computer has pushed the portability and powerful functions of virtual instruments to a new level. All these will accelerate the development of virtual instrument, and make its functions and application fields continue to strengthen and expand

different from the conventional temperature calibration system, the core of the virtual instrument system is a computer. Its functional hardware is a high-precision digital multimeter with GPIB interface and a temperature regulator. The heating control route is a strong current thyristor element and trigger circuit, which receives the command signal of the temperature regulator to adjust the voltage value of the heating element in the verification furnace. If the electronic automatic switch is added, the automatic calibration of multiple thermocouples and thermometers in the same furnace can be realized

the temperature calibration system based on virtual instrument can fully meet the requirements of calibrating different thermometers with different standard equipment in the temperature calibration laboratory. Using a set of hardware equipment and different software, it can meet the calibration requirements of various temperatures and temperature ranges, and has the characteristics of high precision, high efficiency and full automation. It is the development direction of calibration equipment in modern temperature measurement room
