Description
Technical field
The present invention relates to coal chemical industry dry coke quenching equipment field, more specifically to can be carried out to coke dry quenching hoister
Run the systematic difference and design method of forewarning management.
Background technique
Coke dry quenching hoister is one of the important equipment of coal chemical industry dry coke quenching production, is needing to carry out the dry red Jiao Yun put out
It is sent to the dry special equipment for putting out slot, main function is the burnt tank by being promoted with red coke being housed on traversing burnt tank trolley, by coke oven
The red coke of the high temperature produced be fitted into it is dry put out in slot, achieve the purpose that Dry Quenching.
Coke dry quenching body and coke dry quenching hoister are respectively that two sets of different control systems control at present, between two systems
Simple control information exchange is only completed by hardwire, and the control signal and detection data of elevator part lack accordingly
Historical record, when elevator part is broken down, by the existing coke dry quenching body system directly contacted with operator,
Due to lacking the historical data about elevator part, it is difficult to judge the specific failure cause of elevator.Therefore by elevator
It is necessary that historical data participation accident analysis is added in partial key signal and data.
Existing coke dry quenching hoister control system does not have independent man-machine interface, and control system is put out by hardwire with dry
Burnt ontology control system is attached, and the command information from coke dry quenching body is received, inside hoister control system PLC
Logical program, reach automatic lifting and traversing to promoting frequency converter and traveling frequency converter and being controlled.Once elevator goes out
Existing failure then must open hoister control program by professional and be analyzed and deduced one by one, and technical requirements are higher, simultaneously
The difficulty of analysis failure is big, consuming time is long；Even if often in this way, it is also possible to can not because corresponding historical data is lacked
The failure of exact reproduction at that time, causes coke dry quenching hoister system to become a black box, can not carry out to it effectively
Management, operation early warning are even more not know where to begin.
Summary of the invention
1. technical problems to be solved by the inivention
In view of the above deficiencies, the present invention provides application and the design side of a kind of coke dry quenching hoister operation pre-warning management system
Method is diagnosed, analyzed and is recorded dedicated for the operation conditions to coke dry quenching hoister.It being capable of Real-time Feedback elevator fortune
The variation tendency of row process, and change trend curve figure is saved, monitoring easy to produce and failure quickly judge.Elevator is run
In the process the detection of any limit signal lose the failures such as failure, elevator band-type brake failure, elevator car slipping carry out actively, it is automatic real
When early warning.Real-time, automatic monitoring record, friendly interface, even if not having are carried out to the key condition in hoister control program
The programming grounding in basic skills of profession also can know to cause elevator failure cause at the first time by system interface.Meanwhile hardware is put into
Few, network structure is simple.
