Description

Technical Field

[0001] This invention relates to the field of Bluetooth Mesh network technology, and in particular to a silo management method and system based on Bluetooth Mesh monitoring and control. Background Technology

[0002] Bluetooth Mesh is a wireless communication network topology based on Bluetooth technology. Bluetooth Mesh allows for the creation of large-scale multi-point to multi-point networks between devices, where each device is treated as a node and can exchange information, forming a self-organizing, self-healing network system. It uses a "flooding" or "directed broadcast" method to propagate data within the network. Upon receiving information, each node determines whether to process the information based on its destination address, or continues forwarding it to neighboring nodes until the information reaches its destination or a timeout occurs.

[0003] Traditional silo management relies primarily on manual inspections and wired sensors, which presents several technical bottlenecks: manual recording of material level data can be delayed by up to several hours, making it unsuitable for handling sudden material shortages or overflows; wired sensors require penetration of the silo wall, which is difficult to implement in explosion-proof / corrosive environments (increasing costs by 300%); and mechanical level gauges require quarterly calibration, posing significant risks for high-altitude operations.

[0004] To address these issues, there is an urgent need for a silo management method and system based on Bluetooth Mesh monitoring and control. Summary of the Invention

[0005] To address the aforementioned issues, this application proposes a silo management method and system based on Bluetooth Mesh monitoring and control. The silo management method based on Bluetooth Mesh monitoring and control includes the following steps:

[0006] S1. Obtain material warehouse site information, analyze the material warehouse site information to determine the material warehouse site range, material warehouse location, material warehouse category and travel route;

[0007] S2. Construct a network framework based on the silo site area, silo location, silo type, and travel route;

[0008] S3. Determine the type and number of Bluetooth sensors and set their locations based on the type of goods in the silo. Generate a Bluetooth information topology network based on the network framework and the number and location of the Bluetooth sensors.

[0009] S4. Monitor and control the silo based on Bluetooth information topology network.

[0011] Determine the area of ​​the network framework based on the site boundaries of the silo.

[0012] Determine the route, generate the network main line based on the route, and divide the network framework area into several node intervals through the network main line;

[0013] Determine the network mainline width and establish the mainline signal range based on the route width;

[0014] Determine the location of the silo and mark the silo nodes in the node interval;

[0023] The repeated lines of the secondary signal are obtained by performing line repetition statistics and then marked.

[0024] The bin node that has an initial signal repeat line and a secondary signal repeat line is defined as the target adjustment bin node.

[0025] Auxiliary signal lines are established for the sensor position nodes of the target silo node to obtain the Bluetooth information topology network.

[0030] Establish twist nodes in the plane of the reference signal line and the current secondary signal repetition line;

[0031] Connecting the target sensor node, the torsion node, and the signal range loop yields a triple signal line, which in turn forms a Bluetooth information topology network.

The current silo node, its sensor nodes, primary signal lines, secondary signal lines, and tertiary signal lines are simulated to eliminate signal conflicts in the Bluetooth information topology network. The Bluetooth information topology network with the highest signal transmission speed is then selected to obtain the currently accessible Bluetooth information topology network for Bluetooth information transmission.

[0039] The accuracy and smoothness of the discharge are determined by the weight sensor.

[0040] If a blockage occurs, a signal is sent to the vibration sensor to cause the hopper to vibrate;

[0041] If everything goes smoothly, no action is taken.
