Problems solved by technology

[0010] The above-mentioned value document identification system has the following disadvantages: due to the differences in the physical dimensions of various value documents, the data sizes of various value documents are not the same
However, the size of the storage space of each storage unit of the above-mentioned system is fixed. When a piece of valuable file data occupies less space, part of the storage space will inevitably be vacant, resulting in a waste of storage resources and a decrease in the utilization rate of the storage space. Low

Abstract

The invention discloses a valuable file identification method and a valuable file identification system. The method comprises the following steps of: storing the acquired valuable file data into a toroidal enclosed storage area, and recording an initial address and an ending address of a storage space of each piece of valuable file data; and reading each piece of valuable file data from the toroidal enclosed storage area in a first-in first-out order according to the initial address and the ending address, and identifying the legality of each valuable file, wherein the ending address of the storage space of the ith piece of valuable file data is succeeded by the initial address of the storage space of the (i+1)th piece of valuable file data; and when the toroidal enclosed storage area is full, the subsequent data covers the data which is stored for the longest time in the toroidal enclosed storage area. The method can save storage resources and improve the utilization rate of the storage space.

Description

technical field [0001] The invention relates to the technical field of identification of valuable documents, in particular to a method and system for identifying valuable documents that can improve storage space utilization. Background technique [0002] Valuable documents such as banknotes and securities have a large circulation in people's lives and involve a wide range of areas. Anti-counterfeiting identification of valuable documents can prevent the circulation of counterfeit bills and protect people's property safety. [0003] The existing valuable document identification system is based on a point trigger strategy, and photoelectric sensors are installed at the front and rear ends of the identification device as trigger devices for the "start" and "end" of the identification system. Its workflow is as follows: [0004] Step 1, after the current valuable document enters the transmission device, the transmission device transmits the valuable document to the effective de...
