基于ZigBee技术的带压作业监测系统设计

针对目前带压作业有线监测系统存在的布线复杂、安全性差以及难以维护等缺点，设计了一种基于ZigBee技术的带压作业监测系统。该系统包含一个汇聚节点和多个用于参数终端采集的传感器节点，可在无线情况下安全有效地采集带压作业运行过程中的各种数据。数值模拟结果表明，通信距离小于150 m时，丢包率为0；通信距离为200 m时，丢包率为0.4%，系统可够满足实际应用中传输距离为50 m的要求。实际应用结果表明，该系统克服了传统物理布线的束缚，方便高效地实现了数据信息的采集，实现了带压作业的无线监控，在带压作业中具有广阔的应用前景。

Design of monitoring system of snubbing operation based on ZigBee technology

Aiming at the defects existing in the current wired monitoring system for snubbing operation, including complicated wiring, poor anti-interference and difficult maintenance, in this paper, we design a monitoring system of snubbing operation based on ZigBee technology. The system comprises a data base station and several multi-parameter terminal collection nodes, which can safely and effectively collect various data during the operation of snubbing operation equipment under wireless conditions. The numerical simulation results show that the packet loss rate is 0 when the communication distance is less than 150 m, and the packet loss rate is 0.4% when the communication distance reaches 200 m, which shows the system can fully meet the requirements of 50 m transmission distance in practical applications. The practical application results demonstrate that the system overcomes the constraints of traditional physical wiring, facilitates the efficient collection of data information, realizes wireless monitoring of snubbing operation and has wide application prospects in the snubbing operation system.
