Description
Technical field
The invention belongs to on-line checkings and fault diagnosis technology field more particularly to a kind of arc open-close sluice gate status monitoring
With error comprehensive diagnosis method.
Background technique
Arc open-close sluice gate is the common gate type in current hydroelectric power plant, generally comprises gate body construction part and control
Part, control section therein include gate jacking system, gate opening/closing system, hoisting system again.Between these systems both
There are certain independence, and have large effect between each other.The health status of any one system is not single
Factor can be with accurate judgement.Condition diagnosing is carried out to entire gate and health status judgement is even more to have very big difficulty
Degree.Condition diagnosing is carried out to entire gate needs to know the composition of gate various pieces and internal system, internal each component
Between relationship, it is also necessary to know the difference and connection not between homologous ray and part.This connection is only known about, while in shape
State is dispelled during diagnosing and interferes with each other the accuracy that just can guarantee its judging result between this connection.And gate is strong
Health condition diagnosing can judge the health status of gate according to certain algorithm and data relationship, when gate is good for
Can also be provided when Kang Wenti defective locations prompt and best maintenance direction, it is therefore proposed that new arc open-close sluice gate shape
State error comprehensive diagnosis method has a very important significance.
Traditional gate does not carry out status monitoring, even if with the presence of the name of a small number of gate system monitorings, practical institute
What is done is also only to carry out status display to gate status, if paying close attention to display parameters without special messenger's moment does not play monitoring yet
Practical function.
Summary of the invention
The object of the present invention is to provide one kind can be complete, accurate, comprehensive comprehensive to the progress of arc open-close sluice gate
Condition diagnosing and assessment method.
To achieve the above object, the technical solution adopted by the present invention is that: a kind of arc open-close sluice gate status monitoring and synthesis
Diagnostic method, arc open-close sluice gate include sluice control system and gate body construction, and sluice control system includes gate lifting
System, gate opening/closing system and hoisting system；Gate body construction includes that gate door leaf, support arm and branch twist；The following steps are included:
Step 1, the health status monitoring of sluice control system and diagnosis；Directly corresponding control is read from sluice control system
The feedback signal of signal processed and executing agency, according between signal logic and coupled relation judge sluice control system
Health status；
Step 2, the health status monitoring of gate body construction and diagnosis；First determine whether the health status of gate door leaf, so
The health status of gate arm is judged afterwards, finally judges the health status that gate branch twists, so that synthesis obtains gate body construction
Health status, to be in non-health gate area, carry out alarm warning, while providing the portion that gate ontology needs repairing
Position；
Step 3 closes the state of health data of sluice control system and the state of health data of gate body construction synthesis
At obtaining the state of health data of arc open-close sluice gate；
Step 4 receives state of health data by industrial personal computer, carries out signal processing using LABVIEW and data calculate, adopt
The health status monitoring result of arc open-close sluice gate is obtained with fault diagnosis algorithm.
In above-mentioned arc open-close sluice gate status monitoring and error comprehensive diagnosis method, the realization of step 1 the following steps are included:
Step 1.1, the promotion by Modbus ethernet communication reading sluice control system, decline, stopping, safety are made
Dynamic, industrial control for brake output, obtains the status signal of gate jacking system；
Promotion signal, dropping signal, stop signal, safety arrestment signal, industrial brake signal are used group by step 1.2
It is logical, complete the judgement of jacking system health status；When being promoted or dropping signal occurs simultaneously with safety arrestment signal, table
It is abnormal to show that jacking system occurs；When stop signal and safety arrestment signal occur simultaneously, indicate that jacking system is normal；
Step 1.3, the gatage read using RS232 communication modes and gate loading data obtain gate opening/closing system
Health status；
Step 1.4, the healthy shape that gate opening/closing system is judged according to the relationship between gatage and gate loading data
State；Indicate that opening/closing system is normal when gatage is in positive proportionate relationship with gate loading, when gatage and gate loading
It is abnormal in expression opening/closing system when reversed proportionate relationship；
Output voltage, the electric current, frequency, temperature of step 1.5, the rolling control frequency converter read using RS485 communication modes
Degree evidence obtains the status signal of hoisting system；
Step 1.6 is compared judgement elevator with hoist engine output electric current according to the output frequency of rolling control frequency converter
The health status of system；When hoist engine output electric current and rolling control frequency converter output frequency are at positive proportionate relationship, indicate
Gate hoisting system is normal；When hoist engine output electric current and rolling control frequency converter output frequency are at reversed proportionate relationship or at random
When relationship, indicate that gate hoisting system is abnormal；
The health status of step 1.7, comprehensive gate jacking system, opening/closing system, hoisting system, according to combinational logic algorithm
Judged, obtains the health status of sluice control system；When in gate jacking system, opening/closing system, hoisting system any one
A failure is then judged as that there are failures for sluice control system.
In above-mentioned arc open-close sluice gate status monitoring and error comprehensive diagnosis method, the realization of step 2 the following steps are included:
Step 2.1 obtains gate door leaf, support arm, branch according to the strain gauge data that Modbus232 communication protocol is read
The status signal of strand；
Step 2.3 is compared according to acquisition strain gauge data with preset threshold value, judges gate door respectively
Page, support arm, branch twist locating health, danger, failure stage, and the health status stage of comprehensive three obtains gate body construction
The health status stage.
In above-mentioned arc open-close sluice gate status monitoring and error comprehensive diagnosis method, judge that gate door leaf, support arm, branch twist institute
The health at place, danger, failure stage the following steps are included:
If step 2.3.1, gate door leaf strain gauge integrated data is more than 20% that gate operates normally data, lock
Door door leaf is failure state；
If step 2.3.2, gate door leaf strain gauge integrated data is more than 10% that gate operates normally data, lock
Door door leaf is precarious position；
If step 2.3.3, gate door leaf strain gauge integrated data is no more than gate normal operation data, gate door
Page is health status；
If step 2.3.4, support arm strain gauge integrated data is more than 25% that gate operates normally data, support arm is
Failure state；
If step 2.3.5, support arm strain gauge integrated data is more than 15% that gate operates normally data, support arm is
Precarious position；
If step 2.3.6, support arm strain gauge integrated data has more than gate and operates normally data, support arm is health
State.
In above-mentioned arc open-close sluice gate status monitoring and error comprehensive diagnosis method, the healthy shape of gate body construction is judged
The stage of state includes: the gate body construction when strain gauge data are less than or equal to the 100% of actual motion maximum data
For health；When strain gauge data are greater than the 100% of actual operating data, less than or equal to actual motion maximum data
When 115%, gate body construction is danger；When strain gauge data are greater than the 115% of actual operating data, less than or equal to real
When border runs the 130% of maximum data, gate body construction is failure.
