[0051] As shown in the figure, Figure 2 is the network mode switching processing logic diagram of the communication system in this embodiment

[0052] The power pole and tower integrated communication system is a multi-network access and switching intelligent gateway device, and the overall logical control is realized by the main control unit.

[0053] The terminal data is accessed to the power pole and tower integrated communication system through the WIFI network or the Ethernet network. By default, 4G is selected for communication under normal conditions, and wireless ad hoc network communication is adopted in the absence of 4G network. 4G communication can directly transmit the data to the monitoring background.

[0054] Wide and Narrow Integrated Wireless Ad Hoc Network Communication

[0055] The wide and narrow integrated wireless ad hoc network technology is a regional coverage networking communication technology, which has the characteristics of self-organization, centerless, and high bandwidth, and is very suitable for use on the linear link of power poles and towers.

[0056] Broadband wireless ad hoc network is a self - formed mesh network. It adopts COFDM modulation and demodulation technology, has strong anti - multipath interference ability, and can better adapt to complex and changeable wireless transmission environments. COFDM, namely coded orthogonal frequency division multiplexing, is the most advanced and promising modulation technology in the world at present. Its basic principle is to convert high - speed data streams through serial - to - parallel conversion and distribute them to several sub - channels with lower transmission rates for transmission; it belongs to a multi - carrier communication scheme with overlapping frequency bands, and selects mutually orthogonal carrier frequencies as sub - carriers.

[0057] Narrow - band ad hoc network is also a kind of mesh network communication. It innovatively realizes automatic relaying between terminals, thus greatly improving the coverage effect and transmission distance. Narrow - band ad hoc network technology does not require routing. Multiple nodes automatically determine whether to start forwarding based on the received signal quality and field strength, promoting the relay from multi - hop single - point relay at the network layer to multi - hop multi - point relay at the physical layer, and from linear relay to mesh relay. It automatically relays by automatically judging the received signal quality and field strength at the physical layer and combines multi - point signals.

[0058] The narrow - band ad hoc network unit establishes a network through direct communication between networking nodes. Each node can act as an intermediate medium for communication to achieve multi - hop transmission of information, thus forming a distributed communication network. This network has the characteristics of self - organization, self - configuration, and self - healing, and can quickly build a temporary communication network without central control or the support of traditional infrastructure; the network topology is dynamically changing, so there is no established regular routing, and temporary nodes relay each other to establish communication.

[0059] The above - disclosed are only the preferred specific embodiments of the present utility model. However, the embodiments of the present utility model are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present utility model.
