The Research Of Mass Storage Measurement Technology

In the transport packaging process,it is an important means to resolve the rationality of packing goods for monitoring and analying the damage of packages.It is an important means to monitor the transportation process of the packages,collect and storge the parameters,reappear the evolution of the parameters in the process of transportation, provide the basis for packaging design and can improve the quality of the packaging design.This topic foces on the storage and reappearation of the system data.This system uses AT89S52 microcontroller as the controlling chip,based on USB HOST technology and uses U disk as a storage medium,record useful data for a long time,develop the software of reproducing data and verify the system stability and reliability through experimental.The main research contents of this topic:1,Through the two aspects analysis of the current storage measurement technology and the circulating environment of packages,the large-capacity data storage program is proposed using U disk as storage devices based on USB HOST technology and has a reasonable choice of three-dimensional accelerometer,three-dimensional rotation rate,three-dimensional magnetic field,temperature 10 parameters and storage the data.2,It researches USB host development system to achieve the microprocessor AT89S52, USB host chip CH375, the cache chip,62256 and U disk hardware connection.It uses C51 language to complete the preparation of the next-bit machine software including the software such as the host controller driver,U disk drive,file system implementation,data reception storage.3,In the VC++6.0 platform,it analys the data storage format and complete the intelligent data logger data analysis software using MFC programming.It can convenience to observe trend of each parameter. 西安理工大学硕士学位论文4,It is proved by experimental validation that it will be stored in large amounts of data through data analysis software reproduce using a variety of U disk storage for a long time aiming for multi-parameter testing and verify system stability and reliability.The experimental results show that the system is stable and reliable.The data storage module can be easily transplanted into a self-storage capacity,and can be changed according to actual requirements.It's maximum storage capacity is up to 4G and reproduction of data can be applied to U disk with a generic.This is conducive to long-distance,long in the transport of real-time record of a complete packaging process parameters and can reproduce the transport packaging process parameter variation.
