Abstract

The invention discloses a process-oriented joint scheduling method for data perception and dynamic priority transmission, comprising the following steps: step 1, setting standard data, collecting field data with sensors and transmitting them to a fuzzy controller; step 2, correcting The collected data is fuzzed, prioritized, and used for protocol conversion with an embedded processor; Step 3: Send the data after protocol conversion to the wireless receiver; Step 4: Send the received data to the server for processing Data analysis and processing; Step 5, the server controls the corresponding device to perform the corresponding adjustment action. The invention can make the industrial field network have expansibility and compatibility, effectively solve the problems of system delay and key data loss caused by heterogeneous protocols in the industrial field, and effectively solve the problem of data concurrency in the embedded system.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a process-oriented joint scheduling method for data perception and dynamic priority transmission. Background technique [0002] Due to the different communication protocols used by industrial equipment manufacturers, the industrial communication protocols are seriously fragmented, the interconnection between equipment is difficult, and the isolated island and local single-point monitoring make the underlying key data unable to be effectively sensed. Accurate detection and real-time perception and feedback control are challenging. For the large-scale process industry, especially the steel manufacturing industry, its process characteristics are complex, multi-process cascade, and the parameters / states of the industrial process have spatiotemporal correlation and high-dimensional dynamics. A large number of heterogeneous industrial devices on site make it difficult to tr...
