The invention discloses a measuring device and a measuring
system with a configuration
file management function, and a configuration
file copying method. The measuring device is provided with a
control unit 2, an input unit 3, a configuration
file storage unit 5, an I / O unit 6, a
user interface unit 8 and a configuration
file management unit 9, wherein the input unit 3, the configuration
file storage unit 5, the I / O unit 6, the
user interface unit 8 and the configuration
file management unit 9 are respectively connected with the
control unit 2; the I / O unit 6 can be connected with
external storage equipment; and by using the configuration file
management unit 9, the
control unit 2 can execute configuration file
mirror image storage operation, namely storing configuration file information in the configuration
file storage unit 5 in the
external storage equipment, and can also execute configuration file
mirror image reading operation, namely executing
mirror image copying operation in the configuration file storage unit 5 according to the configuration file information in the
external storage equipment. The device of the invention is particularly suitable for a
production line which needs to switch configuration states of
measuring equipment continuously, so that a plurality of sets of equipment has the same configuration file quickly and conveniently.
