| With the development of Chinese society,the supply of water resources is constantly increasing,the length of pipelines is increasing year by year,and the phenomenon of water leakage is very serious.The main problem at this stage is that the location of the leak is difficult to find and the repair cannot be carried out in time.In response to the above problems,this paper designs a system that can collect pipeline conditions in real time to protect water resources.This paper designs a ZigBee-based leak detection and monitoring system.The sound sensor collects data and transmits it to the ARM gateway through the wireless sensor network.The ARM gateway sends the data to the upper computer through WIFI.The upper computer uses the algorithm to locate the missing points,thus achieving Monitoring of pipeline conditions.The system design mainly includes four parts: wireless sensor network,ARM gateway,upper computer receiving storage and adaptive time delay algorithm positioning.The wireless sensor network establishes a tree topology through routing nodes,which expands the communication distance of the wireless sensor network.The ARM gateway is connected to the host computer to complete the function of receiving commands and returning data,and the ARM gateway and the coordinator are connected to complete the data collection and receiving functions.The upper computer mainly sends the control node command and receives the data function,and saves the collected data through the database SQL sever2008 and TXT files.Then,the collected data is used to locate the leak point of the pipeline by using an adaptive delay estimation algorithm.After the results of the system test,it is proved that the node can be arranged in a large range and selectively collect data,and the host computer can call the algorithm to process the data,thereby completing the accurate positioning of the missing point.The experiment proves the feasibility of the system and can realize real-time monitoring of the pipeline. |
