Application and design method of an early warning management system for CDQ hoist operation

Abstract

The invention discloses an application and design method for a dry-quenched coke lifting machine operation early-warning management system, and belongs to the field of production equipment for dry-quenched coke in the coal chemical industry. The dry-quenched coke lifting machine operation early-warning management system comprises a signal acquisition structure and an automatic processing system. The signal acquisition structure comprises approaching limits in all positions, lifting encoders, a line feed encoder, a lifting motor frequency converter communication module, a line feed motor frequency converter communication module, a lifting machine steel wire rope roller and a line feed motor reducer. The automatic processing system comprises an industrial computer and a programmable logic controller (PLC) network module which is connected with the industrial computer. The industrial computer and the PLC network module are connected through a network. The PLC network module is installed on an original PLC control system of a dry-quenched coke lifting machine. According to the application and design method for the dry-quenched coke lifting machine operation early-warning management system, the limiting signals in all positions and operating parameters of all encoders and all frequency converters are compared and verified, so that the operation state of the dry-quenched coke lifting machine is reflected really, and the purposes that early warning is conducted quickly and accurately and fault message is recorded are achieved.

Description

technical field [0001] The present invention relates to the field of coke dry quenching equipment in the coal chemical industry, and more specifically, relates to the application and design method of a system capable of performing early warning management on the operation of a coke dry quenching hoist. Background technique [0002] The CDQ hoist is one of the important equipments for CDQ production in the coal chemical industry. It is a special equipment for transporting the red coke that needs to be CDQ to the CDQ tank. Its main function is to lift and move the coke tank trolley The coke tank of red coke, the high-temperature red coke produced by the coke oven is put into the dry quenching tank to achieve the purpose of dry coke quenching. [0003] At present, the CDQ body and the CDQ hoist are controlled by two different control systems, and the simple control information exchange is only completed through hard wiring between the two systems, while the control signals and ...

Problems solved by technology

Once the hoist breaks down, professionals must open the hoist control program to analyze and deduce one by one. The technical requirements are high, and it is difficult and time-consuming to analyze the fault. Even so, it may be due to lack of corresponding history Data cannot accurately reproduce the fault at that time, causing the CDQ hoist system to become a "black box", which cannot be effectively managed, and the operation warning is impossible to talk about
