    摘要:

    爆炸場(chǎng)振動(dòng)測試中節點(diǎn)分布范圍廣、數量多,對各測試節點(diǎn)的狀態(tài)監控及全局管理難以有效實(shí)現,傳統測試方案中節點(diǎn)部署后難以快速更改狀態(tài)。針對上述問(wèn)題,依據模塊化、標準化和穩定性原則,設計了一種基于無(wú)線(xiàn)技術(shù)的振動(dòng)監測系統。給出了爆炸場(chǎng)振動(dòng)監測系統的基本功能單元,包括數據采集設備、無(wú)線(xiàn)組網(wǎng)設備。數據采集設備具有高精度采集、數據存儲、高精度同步、定位定姿等功能;利用無(wú)線(xiàn)網(wǎng)橋技術(shù)構建了覆蓋廣域范圍的無(wú)線(xiàn)網(wǎng)絡(luò ),支持IEEE802.11n/ac協(xié)議,實(shí)現了對遠程分布式測試節點(diǎn)的集中管理、狀態(tài)監控、數據傳輸,也可對指定測試節點(diǎn)的工作模式進(jìn)行快速設置,以滿(mǎn)足測試需求。測試節點(diǎn)的振動(dòng)測量范圍為0~10g,室外1公里數據傳輸。通過(guò)模擬測試試驗驗證了系統的有效性,各項功能滿(mǎn)足工程需要。

    Abstract:

    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 IEEE802.11n/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 0~10g, 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.
