|
摘要
针对独立式PDE台架和外场试验在线监测需求,提出了基于无线传感器网络的在线监测方案;设计并实现了由在线监测单元和手持单元组成的在线监测系统。该系统具有小型化,集成度高,独立运行,便携性强的特点;满足爆震腔压力高速远程监测,数据实时处理、存储、管理和导出,远程控制,无线自组网等监测要求;解决了现有方案无法适应独立式PDE在线监测的问题。采用在线自动计算爆震特征参数和统计信息的方式代替手工计算,大大提高了科研效率,具有较强的实际应用价值。
An online monitoring plan based on wireless sensor network was proposed to meet requirements of bench and field test for stand-alone PDE. And an online monitoring system consisting of an online monitoring unit and a handheld unit was designed,which is characterized by miniaturization,high integration,independent operation and strong portability. It meets the requirements of remote and high-speed pressure monitoring for detonation chamber,real-time data processing,storage,management and export,remote control,wireless network self-organization etc..To make scientific research more effective,the detonation characteristic parameters and statistical information are automatically calculated instead of manual calculation.
