爆炸场振动测试中节点分布范围广、数量多,对各测试节点的状态监控及全局管理难以有效实现,传统测试方案中节点部署后难以快速更改状态;针对上述问题,依据模块化、标准化和稳定性原则,设计了一种基于无线技术的振动监测系统;给出了爆炸场振动监测系统的基本功能单元,包括数据采集设备、无线组网设备;数据采集设备具有高精度采集、数据存储、高精度同步、定位定姿等功能;利用无线网桥技术构建了覆盖广域范围的无线网络,支持IEEE802.11 n/ac协议,实现了对远程分布式测试节点的集中管理、状态监控、数据传输,也可对指定测试节点的工作模式进行快速设置,以满足测试需求;测试节点的振动测量范围为0~10 g,室外1公里数据传输;通过模拟测试试验验证了系统的有效性,各项功能满足工程需要。

In the explosion field vibration test,the nodes are distributed in a wide range and large number.It is difficult to effectively realize the status monitoring and global management of each test node.In the traditional test scheme,it is difficult to quickly change the status of the nodes after deployment.In response to the above problems,a vibration monitoring system based on wireless technology was designed based on the principles of modularity,standardization and stability.The basic functional units of the explosion field vibration monitoring system are given,including data acquisition equipment and wireless networking equipment.The data acquisition equipment has the functions of high-precision acquisition,data storage,high-precision synchronization,positioning and attitude determination;it uses wireless bridge technology to construct a wireless network covering a wide area,supports the IEEE802.11 n/ac protocol,and realizes remote centralized management,status monitoring,and data transmission of test nodes can also quickly set the working mode of designated test nodes to meet test requirements.The vibration measurement range of the test node is 0~10 g,and the outdoor data transmission is 1 km.The effectiveness of the system is verified through simulation tests,and various functions meet the needs of the project.
