一种基于智能终端的温度/振动点检系统设计

Temperature/Vibration Spot Inspection System Based on Intelligent Terminal

工业设备在故障发生前通常伴随着异常振动或者局部超阈值高温,针对机械设备重要环节实施振动、温度监测对机械设备安全可靠运行和故障预警具有重要意义。鉴于当前设备状态点检系统自动化程度低、数据汇总滞后等问题,提出一种基于智能终端的温度/振动点检系统。系统由状态监测层、点检终端层和数据汇总层组成。状态监测层基于红外温度传感器和ICP型加速度传感器设计了便携式状态监测节点;点检终端层以Android系统为开发平台设计了终端软件,软件功能包括:数据曲线绘制、阈值报警、历史数据查看和数据统计参量获取等;数据汇总层利用Java和MySQL设计实现了数据库服务器。系统验证实验结果表明:状态监测节点加速度、温度测量准确,相比于标准测量系统,本系统加速度测量最大相对误差为0.21%,终端软件和数据库服务器运行正常,符合预期设计目标。

Industrial equipment is usually accompanied by abnormal vibration or local over-threshold high temperature before a fault occurs.Vibration and temperature monitoring of important parts of mechanical equipment is of great significance for the safe and reliable operation of mechanical equipment and fault early warning.In order to solve the problems of low degree of automation of the current equipment status inspection system and lag in data collection,a temperature/vibration spot inspection system based on intelligent terminals is proposed.The system consists of three layers:the status monitoring layer,the inspection terminal layer,and the data summary layer.Based on an infrared temperature sensor and an ICP acceleration sensor,a portable status monitoring node is designed in the status monitoring layer.In the inspection terminal layer,the Android system is used as the development platform to design the termnal software.The software functions include that data curve drawing,threshold alarm,historical data viewing,and data statistics parameter acquisition.In the data summary layer,Java and MySQL are used to design and implement the database server.The results of system verification experiments show that the acceleration and temperature measurements of the condition monitoring nodes are accurate.Compared with the standard measurement system,the maximum relative error of the acceleration peak measurement of this system is 0.21%.The terminal software and database server are running normally,in accordance with the expected design goals.
