【摘要】:針對遠(yuǎn)程自動抄表系統(tǒng)數(shù)據(jù)采集和存儲的高可靠性要求,設(shè)計一種掉電安全和資源緊湊的輕量級Flash文件系統(tǒng)。該文件系統(tǒng)采用分層、模塊化和跨平臺設(shè)計,方便移植到包括ARM Cortex-M系列單片機(jī)在內(nèi)的各種資源緊張的MCU平臺,具有較高的靈活性和通用性。為實現(xiàn)數(shù)據(jù)掉電安全,采用類似于日志文件系統(tǒng)的設(shè)計思想。將Flash空間劃分為5個區(qū)域,使用若干物理頁面作為管理區(qū),記錄文件系統(tǒng)的安全寫入和擦除操作。使用Freescale MK60硬件平臺和MQX操作系統(tǒng)對該Flash文件系統(tǒng)進(jìn)行測試和現(xiàn)場驗證,結(jié)果表明,該文件系統(tǒng)資源占用少、可靠性高,能滿足遠(yuǎn)程自動抄表系統(tǒng)數(shù)據(jù)存儲要求。
[Abstract]:According to the high reliability of remote automatic meter reading system of data acquisition and storage requirements, design a power down safety and resources compact lightweight Flash file system. This file system uses a hierarchical, modular design and cross platform, easy to transplant to include all kinds of resources of ARM Cortex-M series single-chip microcomputer in the tension in the MCU platform, has high flexibility and universal. To achieve power down data safety, the design is similar to the log file system. The Flash space is divided into 5 regions, the use of some physical pages as a management area, file system security write and erase operation. Using the Freescale MK60 hardware platform and MQX operating system test and field test of the results show that the Flash file system, the file system occupies less resources, high reliability, can satisfy the remote automatic meter reading system data storage requirements.
