Implementation Of 3D Vibration Equipment Monitoring System Based On OpenGL

In the process of industrial production and manufacturing,the equipment with stringent requirements for working environment must undergo strict screening before delivery and use of products to meet specific environmental requirements especially military equipment and automotive electronics.Vibration experiment is one of the indispensable selecting experiment.The 3D remote monitoring system overcomes the disadvantage of the traditional experimental process in which the experimenters need to enter the laboratory with small space and large noise and use a lot of time to check the operation status of the equipment for vibration.It is a more convenient,remote and traceable monitoring system for experimenters.Based on the practical application and combined with the current Windows and Linux operating systems,this paper designs a monitoring system which can monitor the operation status of each module in the vibration system to cooperate with the vibration experiment.This system provides a vivid 3D interface and convenient query operation for the experimenters.At the beginning of this paper,the research background and current situation of 3D interface are described.Secondly the cross-platform technology and mathematical theory of OpenGL ES programmable pipeline technology are studied.Thirdly,the core technology used in the design of monitoring and vibration equipment system is described in detail,focusing on the research of 3D model analysis and model picking algorithm.At the same time,the requirement,overall design and CAN communication protocol used in the monitoring vibration equipment system are described.The system consists of display and control terminal and monitoring terminal.The monitoring terminal consists of STM32F103C8T6 chip,temperature sensor,voltage acquisition circuit and CAN physical layer circuit.The monitoring terminal collects the working voltage,temperature and some important analog signals of the monitored equipment in real time,and sends the acquired data to the display and control terminal through CAN bus.The display terminal is equipped with Cortex-A9 processor,loads the three-dimensional model of the vibration equipment,and parses the realtime data sent by each monitoring terminal according to the ID number of each module,and reflects the real-time data on the three-dimensional interface.Then,the design of software and hardware in the monitoring terminal is described,as well as the specific design of each module of the display and control terminal software.Finally,the whole system is debugged and tested.The experimental results show that the system has smooth interface,stable operation.It can basically meet the functional requirements of vibration experiment.
