Embodiment Construction

[0027] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0028] In the prior art, a mesh network is formed between sensor nodes, and then APs are connected to a central terminal through a star network. The disadvantage of this design is that the system cannot be applied to the application of ultra-long-distance sensor nodes. At the same time, a large number of mesh networks are used in sensor nodes, resulting in high energy consumption of a large number of nodes. Therefore, embodiments of the present invention such as figure 1 As shown, a two-layer MAC sensor network control system is provided, which includes multiple sensor nodes 11, ...

The method is applied to an access point AP in a wireless sensor network, and the APs in the wireless sensor network form a mesh network, and each AP manages a plurality of sensor nodes, and the method includes: receiving a message frame, and determining the received message frame The frame type of the message frame; according to the frame type, determine the processing mode of the message frame. The embodiments of the present invention are applicable to the monitoring process of transmission lines.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a double-layer MAC sensor network control method, device and system applied to transmission line monitoring. Background technique [0002] The wireless sensor network is composed of a large number of ubiquitous tiny sensor nodes with communication and computing capabilities densely deployed in unattended monitoring areas. It is an "intelligent" autonomous measurement and control network system that can independently complete specified tasks according to the environment. [0003] The main problems of wireless sensor networks are signal coverage and energy consumption. The application of wireless sensor networks in industrial monitoring and other aspects requires nodes to be powered by batteries, and the network life should reach 2-3 years, and the problem of energy consumption is more prominent. However, the existing wireless sensor network uses mesh networ...
