水下信号是流量测验的关键信息,要想使测流历时短、测流精度高,特别是能够被计算机识别,就必需有可靠稳定的编码和传输方式。本文简要介绍了实现缆道水下信号无线传输的一种方式。 Underwater signal is the key information of the flow test. If it is necessary to make the measurement flow lasted short and the accuracy of the flow measurement high, especially if it can be recognized by the computer, it is necessary to have a reliable and stable coding and transmission method. This article briefly describes a way to achieve wireless transmission of cable under water signals.
