Before-destroy detection device and method for damaged RMB notes

Abstract

The invention provides a before-destroy detection device for damaged RMB notes. The device comprises a product feeding conveyer, a detection imaging device, a data storage device and a PLC control system device. The detection imaging device includes four independent product number detection units and a metal foreign matter detection unit, the units are positioned in different positions of the product feeding conveyer respectively, and each of the four independent product number detection units includes a whole-bag number detection unit and a bundle detection unit. A destroy product conveying system is designed, a production information and number detection system is installed on the conveying system, the states of the destroy products are monitored in real time, alarm against abnormity ofthe products is more timely, digital risk is prevented effectively, damage of abnormal product destroy on equipment is reduced, and an image identification method is used to monitor the product digital safety before destroy of the damaged RMB notes.

Description

technical field [0001] The invention belongs to the technical field of image recognition, and in particular relates to a detection device and a detection method for damaged RMB before destruction. Background technique [0002] RMB destruction equipment is a large-scale special equipment developed for the destruction of damaged RMB. The production and processing process of the old banknotes recovered from commercial banks by the Banknote Processing Center of the People's Bank of China includes sorting, counting, labeling, packing, unpacking, counting and secondary review, and destruction. In these links, the production process of product destruction is divided into two business processes: machine automatic destruction and manual destruction. Automatic destruction is mainly aimed at recovering products with better quality. Manual destruction is aimed at products that are of poor recycling quality and cannot be automatically destroyed by machines. These products are completely...

Problems solved by technology

In the actual operation process, digital security is extremely important. Due to abnormal conditions such as loose bundles and loose handles, the number of bundled products is less than 10 after being bundled, resulting in digital risks. At the same time, due to human factors, the products are mixed with metal coins. When these products are crushed in the machine, it will cause damage to the machine. Mixing other products of the same type will cause digital security. At the same time, the process stipulates that the envelopes mixed in the product must be manually confirmed.

At present, in these production processes, it is completely dependent on the manual operation of each station, so there are certain risks and hidden dangers of digital security
