A State Monitoring and Comprehensive Diagnosis Method for Arc Opening and Closing Gates

Abstract

The invention relates to the online detection and fault diagnosis technology and particularly relates to a comprehensive state monitoring and diagnosis method for an arc-shaped opening and closing gate. A corresponding control signal and a feedback signal of an actuator from a gate control system are read; a health state of the gate control system is determined according to the logic and couplingrelationship between the signals; a health state of a gate page is determined, a health state of a gate arm is determined, a health state of a gate hinge is determined, a health state of a gate body structure is obtained, and a part of the gate body needing to be repaired is further given; health state data of the gate control system and health state data of the gate body structure are synthesizedto obtain health state data of the arc-shaped opening and closing gate; the health state data is received through an industrial computer, LABVIEW is utilized for signal processing and data calculation, and the fault diagnosis algorithm is utilized to obtain the health state monitoring result of the arc-shaped opening and closing gate. The method is advantaged in that effective reference can be provided for health state monitoring and diagnosis of the arc-shaped opening and closing gate.

Description

technical field [0001] The invention belongs to the technical field of online detection and fault diagnosis, and in particular relates to a state monitoring and comprehensive diagnosis method of an arc-shaped opening and closing gate. Background technique [0002] The arc opening and closing gate is a commonly used gate type in hydropower plants. It usually includes a gate body structure and a control part. The control part also includes a gate lifting system, a gate opening and closing system, and a hoisting system. These systems are not only independent to a certain extent, but also have great influence on each other. The health status of any system cannot be accurately judged by a single factor. It is very difficult to perform status diagnosis and health status judgment on the entire gate. To diagnose the status of the entire gate, it is necessary to know each part of the gate, the internal composition of the system, the relationship between internal components, and the...

Problems solved by technology

[0003] Traditional gates do not carry out state monitoring. Even if there are a few gate systems in the name of monitoring, what they actually do is only to display the state of the gate. If there is no dedicated person to pay attention to the display parameters at all times, it will not play a practical role in monitoring.
