Description

technical field [0001] The invention relates to the technical field of signal acquisition systems, in particular to a wireless network acquisition system for pipeline water leakage signals. Background technique [0002] The application of network information technology has brought a huge impact on human life and social economy. It mainly covers a variety of new network communication technologies: wireless communication technology, sensor technology and information distributed processing technology. [0003] Water is the foundation of the survival of all living things. The factors that lead to the shortage of water resources today are not only the lack of fresh water resources and human pollution, but also the waste of water resources. This has a profound negative impact on people's lives and even economic development. . The leakage of pipes we encounter daily is one of the main phenomena of waste of water resources. At the same time, many secondary disasters may also occur...

Problems solved by technology

However, water pipes are prone to water leakage. When the pipe leaks, it will interact with the surrounding environment to generate vibrations of different frequencies, and the water leakage signal is generated from this.

The work of data collection of water leakage signals is generally carried out by hand-held related test instruments to obtain on-site sensor data. The data collected in this way is not real-time enough, the error is relatively large, and the uncertainty of the harsh on-site environment makes it difficult to collect on-site data. implementation so it is difficult to meet people's requirements for real-time field data
