Description

Nuclear power station digital RP certificate generation method Technical Field The invention relates to the technical field of nuclear power station digitization, in particular to a nuclear power station digital RP certificate generation method. Background The traditional radiation control area pass (RP card) is used in a mode that personnel entering the radiation control area in the nuclear power station need to transact the radiation control area pass, and personnel identity identification and verification are carried out by manually brushing two-dimension codes of the RP card, and enter the radiation control area. At present, the application of the pass in the radiation control area firstly requires the application of certificates in a personal dose management system (PDMIS), and after the approval is passed, the personnel is required to go to a certificate-handling room for identity verification, the irradiation monitoring in a Whole Body Counter (WBC), the RP (radio frequency) certificate acquisition and the information confirmation authorization are started for 4 steps. After RP certificate handling is completed, staff can enter personnel identity recognition and verification through two modes of reading the two-dimensional code of the RP certificate by a reader of a sanitary entrance of a radiation control area or manually inputting 8 staff codes, and enter the radiation control area. Long-term practical work finds that the existing evidence handling process has the problems of long evidence handling time, more manual intervention items, large human error risk, low working efficiency, few information acquisition paths, incapability of handling non-working time certificates and the like. In addition, the reader is used for reading the two-dimensional code of the certificate or manually inputting the personnel code, the risks that the malicious overhead other person identity and misoperation cause the user identity to enter the radiation control area and the risks that the carrying of the physical RP card can cause foreign matters in the nuclear island exist. Disclosure of Invention The invention aims to provide a nuclear power station digital RP certificate generation method which improves the management level of a pass in a radiation control area. In order to achieve the above object, the present invention provides the following technical solutions: in one aspect, the invention provides a method for generating a digital RP certificate of a nuclear power station, which comprises the following steps: Step 1, digitizing key information to generate digital identity; Step2, binding the key information in the step 1 to generate a digital RP certificate; step 3, registering the digital identity of the digital RP certificate on the blockchain; and 4, binding the face biological information of the user with the digital RP certificate, and using the digital RP certificate in a face scanning mode. In some embodiments, step 1 specifically includes: step 1.1, carrying out encryption calculation on an identity card number and face information of an applicant to generate a string of encrypted ASCII character strings; Step 1.2, carrying out encryption calculation on the confirmation information passing the examination and approval, the employee identification number of the examination and approval person and the face information of the examination and approval person to generate a string of encrypted ASCII character strings; Step 1.3, encrypting and calculating the monitoring data of the whole body counter passing the examination and approval and the employee identification number and the face information of the whole body counter examination and approval person to generate a string of encrypted ASCII character strings; and 1.4, carrying out encryption calculation on the information confirmation authorization result, the employee's card number of the operator and the face information to generate a string of encrypted ASCII character strings.
