Intelligent industrial control instrument suitable for integrated signal management

Abstract

The invention belongs to the technical field of chemical production equipment, and discloses an intelligent industrial control instrument suitable for integrated signal management. The instrument is provided with a central control unit, an external storage capacity expansion module, a digital decoder, an address matcher, a digital memory, a display module, a power supply module, a system reset module, a system maintenance module, a manual control module, a data interface module and a driving controller module, wherein the central control unit is respectively connected with the external storagecapacity expansion module, the digital decoder, the address matcher, the digital memory, the display module, the power supply module, the system reset module, the system maintenance module, the manual control module, the data interface module and the driving controller module. According to the scheme of the invention, serial bus data can be directly input, and multiple instruments can be connected in parallel to a serial data bus, can separately receive and read the own data through the serial bus, and can work independently; and the instrument is suitable for industrial control of various serial bus protocols, and has complete functions.

Description

technical field [0001] The invention belongs to the field of chemical production equipment, in particular to an intelligent chemical control instrument suitable for integrated signal management. Background technique [0002] A digital meter is a meter that displays the measured value digitally. An instrument that converts measurements into digital quantities and displays them in digital form. In industrial measurement, the measured variables or analog quantities such as displacement, current, voltage, and air pressure are converted into digital quantities through an analog-to-digital converter (referred to as analog-to-digital conversion). The digital instrument displays the measured value in digital form, and the reading is intuitive. Generally include: use the dial and pointer to indicate the power, use the electromagnetic force-based electrical measurement circuit, analog-to-digital conversion and digital display. Existing digital display instruments are mainly designe...

AI Technical Summary

Problems solved by technology

[0009] To sum up, the problems existing in the prior art are: the existing instruments cannot directly input and read serial bus data, the transmission distance is relatively short, and the error is large, which cannot meet the needs of producers
