Measurement equipment with file reading function and file reading device

Abstract

The invention provides a file reading device for measurement equipment and the measurement equipment with a file reading function. The device comprises a reading unit, a display unit and a judging unit, wherein the reading unit is used for reading file information under the current directory from a memory to an internal memory of the measurement equipment when entering the current directory; the display unit is used for displaying subdirectories under the current directory on a display on the measurement equipment according to the file information in the internal memory; the subdirectories are files and / or file holders; the judging unit is used for judging whether the internal memory is enough when the reading unit reads the file information to the internal memory; when the judging unit judges that the internal memory is enough, the reading unit continues the reading until all the file information under the current directory is read into the internal memory; and the file information under the former directory is cached in the internal memory. According to the file reading device, corresponding file information is directly read from the internal memory to display when the former directory is visited for the next time, so that the reading time is saved and the users can check conveniently and rapidly.

Description

Technical field [0001] The present invention relates to the technical field of test and measurement, and in particular to a file reading device for measurement equipment and a measurement equipment with file reading function. Background technique [0002] The measuring device can read and display the files stored in the memory. The memory can be the internal memory of the measuring device itself or an external memory, such as a U disk. First, enter the current directory from the display interface of the measuring device, and read the file information in the current directory from the memory to the running memory. The file information is usually the first-level subdirectory (file and / or file) in the current directory. Folder) file name, file size, file attributes, etc., and then read the file information from the memory to display it to facilitate the user to view, select, open and other operations. The displayed content will usually be similar to that on the PC Ways to display d...
