With the development of intelligence in the industrial industry, more and more intelligent instruments and meters are being applied in various industrial settings. Compared with traditional mechanical instruments, intelligent instruments have the advantages of easy installation, beautiful appearance, high measurement accuracy, and convenient parameter modification. Here are some relevant knowledge about intelligent instruments and meters, to share with everyone.

1. The basic working mode of intelligent instruments and meters:

① Base type instrument: Users press the buttons on the panel to issue commands to the instrument. Modifying parameters is particularly convenient.

② Remote control instrument: Users command and control the instrument through an external microcomputer

2. The working characteristics of intelligent instruments and meters:

① High measurement accuracy and considerable cost-effectiveness;

② Capable of conducting indirect measurements;

③ Capable of automatic calibration;

④ Capable of automatically correcting errors;

⑤ Capable of self diagnosis;

⑥ Capable of implementing complex control functions;

⑦ Allow flexible changes to the functionality of the instrument;

⑧ It is convenient to form a complex control system with multiple instruments through a standard bus.

3. Design Ideas for Intelligent Instruments

① Functional requirements for analytical instruments and formulation of overall design plan

② Determine the hardware structure and software algorithm

③ Developing logic circuits and programming

④ Debugging and performance testing of instruments

4. The advantages of modular design

Regardless of hardware or software, each module is relatively independent, so it can be independently developed, thus simplifying complex development work. The modular design approach facilitates the decomposition of development work and the division of labor and cooperation among design and development personnel, thereby improving work efficiency and development speed.

From the current trend of industrial development, intelligent instruments and meters are far from reaching the height they can develop. In the near future, the replacement of traditional instruments with intelligent instruments is irreversible.
