Description
technical field [0001] The invention relates to a file management system, in particular to a file cabinet control circuit and control method. Background technique [0002] The traditional paper file management method simply stores file files in filing cabinets and manages them through paper records. When in use, the inquiry of archives and management of entry and exit are realized by consulting paper records, which has the disadvantage of inconvenient use and complicated management. [0003] The file management system includes filing cabinets and several small cabinets with numbers in the filing cabinets. The filing cabinets are connected to the host computer. There are access ports on the filing cabinets. The small cabinets can move up and down and in parallel in the filing cabinets. To the access port, it is convenient to enter and exit the warehouse. The small cabinet can be automatically operated by the computer software of the upper computer, or it can be controlled by...
