[0002] With the rapid development of my country's economy and cities, there are more and more deep foundation pit projects, the scale of construction is getting larger and larger, and the surrounding environment of foundation pits is becoming more and more complex. The probability of engineering accidents in foundation pits is often higher than that of main projects on the ground. , once an engineering accident occurs, it will seriously endanger the life and property safety of the country and the people. Due to the complexity, nonlinearity, and uncertainty of foundation pit engineering, it is not yet possible to find a systematic and reliable method to judge the foundation pit. Therefore, foundation pit monitoring is an important means to prevent foundation pit safety accidents

[0003] At present, the monitoring of foundation pit engineering includes manual monitoring and wired automatic monitoring. Traditional manual monitoring is mainly equipped with testers to collect on-site data, and then go to the room for data sorting, statistics, analysis and judgment of monitoring results, and issue corresponding monitoring reports. Not only Time-consuming, labor-intensive, low-efficiency, low frequency of project monitoring, and discontinuous monitoring data, resulting in greatly reduced ability to respond to emergencies, processing, and early warning; the wired network monitoring system has improved data collection methods, reducing labor costs. However, a large number of long-distance lines need to be laid to ensure the transmission of power and signals. The surrounding construction environment of the foundation pit project is very complicated, which is easy to cause damage to the wires; wired sensing devices cannot be installed in a large area and in a large density, resulting in false alarms and false alarms. The phenomenon is equally serious
