Description

Technical Field

[0001] The present invention relates to the technical field of Bluetooth Mesh networks, and particularly to a silo management method and system based on Bluetooth Mesh monitoring and control. Background Art

[0002] Bluetooth Mesh is a wireless communication network topology based on Bluetooth technology. Bluetooth Mesh allows the creation of large-scale multi-point-to-multi-point networks between devices. Each device is regarded as a node and can transmit information to each other, forming a self-organizing and self-healing network system. It uses the method of "flooding" or "directed broadcast" to spread data in the network. After each node receives the information, it will judge whether it needs to process the information according to the destination address of the message, or continue to forward it to adjacent nodes until the information reaches the destination or times out and stops.

[0003] Traditional silo management mainly relies on manual inspections and wired sensors, and there are the following technical bottlenecks. The delay in manually recording the silo level data is up to several hours, and it is impossible to cope with sudden material shortages or overflows. Wired sensors need to penetrate the silo wall, and it is difficult to construct in explosion-proof / corrosive environments (the cost increases by 300%). Mechanical level gauges need to be calibrated every quarter, and the risk of working at heights is high.
