Engineering machinery assembly line online perception system

Abstract

The invention discloses an engineering machinery assembly line online perception system and belongs to the field of intelligent manufacturing. The engineering machinery assembly line online perceptionsystem comprises an automatic production line; the automatic production line comprises a plurality of assembling stations; a field sensor, an equipment sensor, an information scanning terminal and astation controller are arranged on each assembling station, the field sensor and the equipment sensor are connected with the station controller by ZigBee communication, and the information scanning terminal is connected with the station controller by RS485 communication; all the station controllers in the same workshop are connected with an industrial control computer by CAN buses; and all the industrial control computers are connected with a server by Ethernet, and the server is connected with a factory monitoring center. According to the engineering machinery assembly line online perceptionsystem disclosed by the invention, online acquisition on multi-source data in the industrial field is based on network interconnection, real-time perception and dynamic control on the production process and rapid response and processing on an abnormal condition can be implemented, and data support is provided for line body balanced analysis, system autodiagnosis, product quality tracing, flexiblemanufacturing and the like.

Description

technical field [0001] The invention relates to the field of intelligent manufacturing, in particular to an online sensing system for an assembly line of construction machinery. Background technique [0002] At present, there are more than 10 million construction machinery and equipment in service in the world, including 4 million in-service equipment in my country, which are distributed on construction sites in more than 150 countries and regions. The final product assembly (final assembly) of construction machinery, equipment manufacturing and other types of enterprises is a complex activity involving many factors such as materials, personnel, and machines. [0003] The production process perception of construction machinery mainly refers to the perception of various production process states in the assembly workshop, involving production execution status, production quality management and other aspects. In the traditional production process information acquisition mode, ...

AI Technical Summary

Problems solved by technology

In the traditional production process information acquisition mode, even with the help of other information systems, there are still problems such as time-consuming, lagging, and no value-added information collection: production execution status information such as production status, production progress, and inspection results Production quality information is manually entered into the information system; however, as the scale of the production process becomes increasingly complex and production factors change randomly, the information in the production process presents a multi-source and massive feature. If If the traditional model is adopted again, problems such as time-consuming, lagging, and errors will become more prominent. At the same time, it will also take up the labor time of workers and waste production resources.
