Big data system architecture intelligent universal meter

Abstract

The invention discloses a big data system architecture intelligent universal meter, belonging to the field of intelligent manufacturing and being a new generation intelligent universal meter. The universal meter is provided with seven keys including a resistor key omega, a DC voltage key DV, an AC voltage key AV, a DC current key DV, an AC current key AA, a multifunctional key M and a reset key R, and the keys substitute more than twenty shifts of a digital universal meter; one-key shifting and one-station measurement are realized; only two input jacks including a VA omega and a COM are provided, a meter pen is pulled out or plugged never; an Ohm shift has three functions of measuring on and off of a resistor, a diode and a buzzer; the big data system architecture and data integration storage processing are used as a core technology for an instrument, the conventional layered structure is broken, merging with a network is realized, and an AC-DC dual-purpose 5V power supply is used. The big data system architecture intelligent universal meter breaks technology and structure patterns of the existing digital instrument, and the core technology supports creation of the new generationintelligent instrument series productions.

Description

technical field [0001] Belonging to the field of intelligent manufacturing, it is an intelligent multimeter that completely subverts the existing technology. Background technique [0002] Digital multimeters originated in the era of industrial automation and are widely used in various fields of production and life in human society. In the forty years since its introduction, its popularity has reached ubiquitous proportions. After entering the new century, its basic architecture and core technology have seriously deviated from the requirements of the information age, making data collection one of the major bottlenecks in big data, Internet of Things and artificial intelligence technologies. The backwardness of digital multimeter technology is mainly manifested in the following aspects: [0003] one. The structure is complex and the use is cumbersome. [0004] There are more than 20 measurement gears of resistance, voltage and current of the digital multimeter with manual ...

AI Technical Summary

Problems solved by technology

During the measurement process, the test leads are frequently inserted and inserted between the voltage and current jacks, which is not only troublesome, but also often loosens the binding posts, which affects the measurement accuracy at least, and must be repaired after opening the cover.

What is even more troublesome is that the milliampere level and the ampere level use two kinds of fuses, and the fuse will be blown if you are not careful; because of the greater risk of large current measurement, high-end multimeters use expensive fast-acting fuses However, when measuring large currents, technicians are still in fear, and even have to temporarily switch to low-grade multimeters

Despite decades of research and development by countries all over the world, the measurement and protection technology of multimeter high current has not achieved a qualitative breakthrough

[0006] 2. Backward software and core technology

For the protection of high-current gear, except for the use of fast fuses, the industry has no good solution.

[0008] 3. Worldwide, there is no progress in the technology research and development of smart multimeters

[0011] The intelligentization of multimeters has become a technical problem that people have been eager to solve but have not been successful in the world.
