A fault diagnosis method and system for an automatic production line of prefabricated concrete structures

Abstract

The present invention provides a prefabricated assembling concrete structure automatic production line fault diagnosis method and system, belonging to the building industrialization technology field. The real-time operation state of the automatic production line of a prefabricated assembling concrete structure is monitored, and automatic and rapid diagnosis and alarm and fault location can be realized. The method comprises: setting the automatic production line fault diagnosis system into two levels consisting of a field pre-diagnosis layer and a concentration analysis layer, the controller of the field pre-diagnosis layer performs primary localization of the fault phenomenon through logic determination to set a primary fault code for each fault state and upload data; and the concentration analysis layer analyzes the primary fault code of each fault state to deduce a final fault diagnosis result. The maintenance time is reduced, and the influence and the loss caused by production line faults are reduced.

Description

technical field [0001] The invention belongs to the technical field of building industrialization and relates to a fault diagnosis system for an automatic production line of a prefabricated concrete structure. Background technique [0002] In recent years, the country has actively promoted green buildings and building materials, vigorously developed steel structures and prefabricated buildings, and the industrialization of construction has ushered in unprecedented opportunities. PC (Prefabricated Concrete Structure) is a "prefabricated concrete structure". It is a concrete structure formed by prefabricated concrete components, assembled, connected, and partially cast in place. It is the development trend of the future construction industry. [0003] The PC automatic production line is mainly used for mass production of architectural concrete prefabricated components (including prefabricated laminated floors, interior and exterior wall panels, stairs, etc.), which requires ex...

Problems solved by technology

[0004] In the existing technology, the PC automatic production line is in the initial stage of development. There are not many manufacturers engaged in the development of the PC automatic production line, and their main energy is also in the development of the function of the stand-alone equipment. There is no precedent for the fault diagnosis system and method for the PC automatic production line. When an abnormality occurs in the operation of the production line, it is often found manually, and then goes to the site to investigate the cause and perform maintenance, which is time-consuming and laborious
