//Project BackgroundWith the advent of the rainy season, the flood season has entered all over the country. In order to prevent rainstorm, thunder and lightning and other bad weather, prevent possible flood disasters, ensure the safety of people's lives and property, fully implement the preventive measures, and make good preparations for flood control, Jinan Boda Communication Technology Co., Ltd. and China Mobile Communications Group launched the construction of urban river flood control projects in early July.After on-site investigation, if fiber optic access is used, the connection of optical cables within the last 1 kilometer of each station in the flood control hydrological station is basically achieved through soil burial, and the soil burial range is basically within the scope of flood erosion. In case of flood season, strong winds and waves, there is a risk of optical cable damage, and the customer has strict requirements, especially during the flood season, the access business must not be interrupted, It is necessary to ensure that customer hydrological data can be transmitted normally, so wireless LAN devices are used for data transmission.One end of the wireless local area network device is installed at the hydrological monitoring station and connected to the customer side monitoring system. The other end is installed on the mobile base station side and uses the mobile base station tower for spatial elevation to achieve bridging and fighting. The two devices complete data exchange and transmit the hydrological station data back to the customer monitoring center through the mobile company transmission network.//Advantages of the plan01 adopts a wireless LAN device networking method, which not only ensures real-time, secure, and stable data transmission, but also avoids the drawbacks and difficulties of laying optical cables, ultimately ensuring data return.02 industrial grade design standard, IP68 protection level, all equipment adopts industrial grade products, effectively supporting the wireless transmission system to work stably and reliably in harsh weather environments such as heavy rainfall.03 adopts a point-to-point networking method, with simple deployment and flexible networking, which meets the transmission of project video images, voice, and monitoring data.
