Problems solved by technology

PLC technology has been widely used, but the reliability of a single controller is low. In order to further improve the reliability of PLC, in recent years, large-scale PLCs have also adopted dual CPUs to form a redundant system, or a voting system with three CPUs.

Abstract

The invention discloses a control system for synthesizing nickel carbonyl through continuous carbonylation. The control system applies interlocking logics between PLC analog quantity and digital quantity, and achieves automatic material discharge and automatic slag discharge of a production device for synthesizing the nickel carbonyl through the continuous carbonylation under a series of logic controls and interlocking conditions. The production device for synthesizing the nickel carbonyl through the continuous carbonylation comprises a storage bin, a first material bin, a second material bin,a horizontal synthesis kettle, a first slag bin, a second slag bin and a third slag bin which are sequentially connected from top to bottom. The control system is convenient to install, easy to operate, high in operating speed, high in reliability, strong in anti-interference ability, easy to use and convenient to debug and maintain.

Description

technical field [0001] The invention belongs to the field of automatic control, and in particular relates to a control system for continuous oxoformation of nickel carbonyl. Background technique [0002] Programmable logic controller (PLC) technology has been widely used in various industries at home and abroad. PLC has replaced traditional relay circuits to realize logic control and sequence control. It can be used not only for the control of a single device, but also for multi-machine group control and automated assembly lines . In the process of industrial production, there are many continuously changing quantities, such as temperature, pressure, flow, liquid level and speed, etc., which are all analog quantities. PLC uses programmable memory to store and execute logic operations, sequence control, Instructions for operations such as timing, counting, and arithmetic operations, and control various types of machinery or production processes through digital or analog input...
