Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments.
Referring to fig. 1 to 4, the AI cloud system for identifying paper money devices provided by the present invention includes an AI cloud platform and at least one paper money device connected to the AI cloud platform via a network, wherein the AI cloud platform includes a paper money identification device, a data acquisition system, a model trainer and an operation system, a data input end of the model trainer is respectively connected to the data acquisition system and the operation system, and a data output end of the model trainer is respectively connected to the paper money identification device and the paper money device.
The paper money identification device is in data connection with the paper money device and is used for identifying paper money to be detected by the paper money device in real time or identifying difficult paper money and feeding back an identification result to the paper money device in real time.
The paper currency recognition device recognizes paper currency through the exceptional recognition rule trained by the model trainer through data fed back by the data acquisition system and the operation system.
The paper money device is in data connection with the data acquisition system, and the data acquisition system is used for acquiring the data of the paper money recognized by the paper money device and sending the data to the model trainer.
The data acquisition system acquires the data of the paper money recognized by the paper money recognizer, wherein the data comprises the serial number of the paper money recognizer, the serial number of the paper money, recognition time, the acquired paper money information (such as fluorescence information, magnetic information, infrared penetration information, laser information and anti-pinching information, the acquired information depends on the detection principle of the paper money recognizer), recognition results (true and false, denomination and country) and front and back pictures (optional) of the paper money.
And the operation system is used for marking the reported identification data or inputting the wrong index of the paper money by an operator and sending the index information data to the model trainer. The operator records the error indexes of the paper money, including a fake-money blacklist (the blacklist is used for vivid fake-money identification and comprises denomination, issuing time and serial number) and error identification label data (paper money device serial number and paper money serial number).
And the model trainer performs paper money model training according to the data provided by the data acquisition system and the operation system to generate a new paper money recognition model and sends the data of the new paper money recognition device to the paper money recognition device and the paper money device. Through AI cloud, real-time update paper currency identification rule, false paper money blacklist improve the discernment degree of accuracy of paper currency ware, reduce fortune dimension cost.
The model trainer forms different characteristics according to different positions of paper money based on collected data, and then learns by using a corresponding machine learning algorithm, such as Bayesian classification, decision tree and the like.
Reducing unidentified banknotes: the collected paper money pictures and the paper money information are labeled by operators, and the machine learning is utilized to become a new identification model.
And distributing a fake banknote blacklist recorded by the operator.
Based on unsupervised clustering learning, feature clustering is carried out on the paper money data reported in real time, clustering abnormity of some exceptional feature (key) features is alarmed in real time, operators are informed to observe in real time, and a large amount of new counterfeit paper money is prevented from being identified.
