Design of Pipeline Displacement Detecting System Based on ZigBee Wireless Sensor Networks
Most of the gravity-dropped slurry pipelines are underlaid in mountainous areas which are vulnerable to disasters,such as debris flow and landslide.The accumulation of displacement of the pipeline caused by those disasters is very likely to cause pipeline fracture.To solve this problem,a design of detection system for displacement of the pipe which is based on ZigBee wireless sensor network and MEMS accelerometer be put forward.This system adopts modular design which includes central processing unit,data acquisition module,serial communication module and human-computer interface.Different detecting points of the pipeline can realize wireless networking and communication by ZigBee Protocol stack.Detecting points use sensor collecting displacement data and uploading data by wireless network step-by-step,last through serial port to upper computer in central control room and display,save it.And according to those data,it can issue warnings in the event of exceeding threshold.Experiments show that the system has a good stability of communication and can collect pipeline displacement data effectively,when the displacement of pipeline exceeding a threshold,it can effective issue warnings.
