Abstract

A river model test multi-channel wireless transmission and receiving communication system comprises an upper computer and a plurality of lower computers. The upper computer is formed by a main control computer, a communication controller and bit stream adapter and a wireless communication module. The main control computer is used for user interaction, code stream calculation, channel setting and channel management. The communication controller and code stream adapter is used for controlling the connection of the wireless communication module. The wireless communication module is used for transmitting and receiving data. The main control computer is connected with the communication controller and code stream adapter which is connected with the wireless communication module. Five wireless channel modules are arranged in the wireless communication modules to be used for representing five types of channels used in a river model wireless communication system, and each wireless channel module manages the data transmission and receiving of a corresponding wireless channel. By means of the system, appropriate wireless channels can be selected automatically to transmit data, the transmission is rapid, and the efficiency is high.

Description

technical field [0001] The invention relates to the fields of adaptive channel switching and data management of multi-channel wireless communication for river engineering model tests, in particular to an adaptive wireless communication control system for river engineering model tests. Background technique [0002] In large-scale river engineering model tests, water level, flow velocity, sand content and wave height are the four commonly used objects to be monitored. There are hundreds of monitoring points, high measurement frequency, and large data transmission volume. All of these cannot be completed by relying on a single wireless channel Real-time detection of parameters. At the same time, the host computer needs to process these measurement data in real time to achieve real-time monitoring. Therefore, multi-channel simultaneous data transmission between wireless modules is required to meet real-time monitoring requirements. For different experimental sites, the actual nu...
