Description

Technical Field

[0001] The present invention relates to the technical field of nuclear power plant digitization, and in particular to a method for generating a digital RP certificate for a nuclear power plant. Background Art

[0002] The usage mode of the traditional radiation control area pass (RP certificate) is: anyone entering the radiation control area in a nuclear power plant must apply for a radiation control area pass, and manually scan the RP certificate QR code to identify and verify the person's identity and enter the radiation control area.

[0003] At present, to apply for a pass to the radiation control area, one must first apply for a certificate in the personal dose management system (PDMIS). After approval, the staff needs to go to the certificate office to undergo identity verification, whole body counter (WBC) internal radiation monitoring, RP certificate collection, and information confirmation authorization. After the RP certificate is processed, the staff can enter the radiation control area by reading the RP certificate QR code through the reader at the sanitary entrance and exit of the radiation control area or manually entering the 8-digit employee code to enter the personnel identity identification, verification, and enter the radiation control area.

[0004] Long-term practice has found that the existing certificate application process has problems such as long application time, many manual intervention items, high risk of human error, low work efficiency, few ways to obtain information, and the inability to apply for certificates during non-working hours. In addition, using a reader to read the QR code of the certificate or manually entering the personnel code may cause the risk of maliciously using someone else's identity or using someone else's identity to enter the radiation control area due to misoperation. The carrying of physical RP certificates may also cause the risk of foreign objects in the nuclear island. Summary of the invention

[0005] The purpose of the present invention is to provide a method for generating a digital RP certificate for a nuclear power plant, so as to improve the management level of passes for radiation control areas.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] In one aspect, the present invention provides a method for generating a digital RP certificate for a nuclear power plant, comprising:

[0008] Step 1: Digitize key information and generate a digital identity;

[0009] Step 2: Bind the key information in step 1 to generate a digital RP certificate;

[0010] Step 3: Register the digital identity of the digital RP certificate on the blockchain;

[0011] Step 4: The user's facial biometric information is bound to the digital RP certificate, and the digital RP certificate is used by facial scanning.

[0012] In some embodiments, step 1 specifically includes:

[0013] Step 1.1: Encrypt the applicant’s ID number and facial information to generate an encrypted ASCII string;

[0014] Step 1.2: Encrypt the approval confirmation information, the approver’s work ID number, and the approver’s facial information to generate an encrypted ASCII string;

[0015] Step 1.3: Encrypt and calculate the approved whole body counter monitoring data and the work ID number and face information of the whole body counter approver to generate an encrypted ASCII string;

[0016] Step 1.4: Encrypt the information confirmation authorization result, the operator's work ID number, and the facial information to generate an encrypted ASCII string.

[0017] In some embodiments, the key information includes personal identity, personal dose management system application process approval results, whole body counter monitoring data, and information confirmation authorization results.

[0018] In some embodiments, step 2 specifically includes:

[0019] Step 2.1: Generate a unique identifier;

[0020] Step 2.2: Bind application record;

[0021] Step 2.3: Encrypt the digital identity of the individual, the approval result of the personal dose management system application process, the whole body counter monitoring data, and the information confirmation authorization result by using an elliptic curve;

[0022] Step 2.4: Generate an encrypted digital RP certificate.

[0023] In some embodiments, the personal digital identity of the applicant is used as the unique identifier of the applicant.

[0024] In some embodiments, each login record includes a digital identity of a personal identity encrypted digital string, a personal dose management system application process approval result encrypted digital string, a WBC monitoring data encrypted digital string, and an information confirmation authorization result encrypted digital string.

[0025] In some embodiments, the digital RP certificate and metadata generated in step 2 are registered on the blockchain along with a unique identifier.

[0026] In some embodiments, the metadata includes creator, creation date, person's facial biometric information, and full body counter history data.

[0027] On the other hand, the present invention provides a computer device, including a memory and a processor, wherein the memory stores computer-readable instructions, and when the processor executes the computer-readable instructions, the steps of the method for generating a digital RP certificate for a nuclear power plant are implemented.

[0028] On the other hand, the present invention provides a computer-readable storage medium having computer-readable instructions stored thereon, and the computer-readable instructions, when executed, implement the steps of the method for generating a digital RP certificate for a nuclear power plant.

[0029] Compared with the prior art, the method for generating a digital RP certificate for a nuclear power plant provided by the present invention has the following beneficial effects:

[0030] The existing technology is to read the QR code of the ID card through a physical reader or manually input the personnel code. In multiple work ticket modes, it must be input manually, which often leads to incorrect operation of input information and affects the traffic efficiency. Especially during overhaul, it is very easy to cause traffic congestion. The present invention greatly simplifies this process. It only needs to be authenticated by a face recognition device to pass quickly, which greatly reduces the incorrect operation of input information and improves the traffic efficiency.

[0031] Under the existing method, the carrying of physical RP certificates may also cause the risk of foreign objects in the nuclear island. The present invention replaces the physical certificate with a digital RP certificate, thereby reducing the risk of foreign objects in the nuclear island.

[0032] In the existing working mode, there is a risk that someone maliciously uses another person's identity to enter the radiation control area. The present invention eliminates this risk from a systematic perspective. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to more clearly illustrate the technical solution of the present invention, the following briefly introduces the drawings required for the technical description.

[0034] Figure 1 The present invention provides a flowchart of a method for generating a digital RP certificate for a nuclear power plant. DETAILED DESCRIPTION

[0035] The following is further explained in detail through specific implementation methods.

[0036] The present invention uses digital certificate technology to create a digital radiation control area pass (digital RP certificate), thereby replacing the use of physical RP certificates. Figure 1 As shown, the present invention provides a method for generating a digital RP certificate for a nuclear power plant, comprising:

[0037] Step 1: Digitize key information and generate a digital identity.

[0038] Key information includes personal identity (ID number and facial information), personal dose management system application process approval results, whole body counter monitoring data, and information confirmation authorization results. Through the digital RP certificate, the digital identity of these four types of information is used as proof of the uniqueness and authenticity of these four types of information. Step 1 specifically includes:

[0039] Step 1.1: Digitize personal identity. Encrypt the applicant’s ID number and facial information to generate an encrypted ASCII string.

[0040] Through the software function of the application system, the ID number and facial information of the person applying for the RP certificate are obtained; the ID number and facial information of the applicant are encrypted and calculated, and the encryption method is not disclosed to generate a string of encrypted ASCII strings. The digitization of the applicant's identity information is shown as follows:

[0041] a1=f(applicant’s identity, applicant’s facial data).

[0042] Step 1.2: Digitize the approval results of the personal dose management system application process. Encrypt the approval confirmation information, the approver's work ID number, and the approver's facial information to generate an encrypted ASCII string. The digitization of the approval results of the personal dose management system application process is shown below:

[0043] a2=f(approval result, approver’s work ID number, approver’s facial data).

[0044] Step 1.3: Digitalization of whole body counter monitoring data. Encrypt the approved whole body counter monitoring data and the work ID number and facial information of the whole body counter approver to generate an encrypted ASCII string. The digitalization of whole body counter monitoring data is shown as follows:

[0045] a3=f(WBC data, WBC approver’s work ID number, WBC approver’s facial data).

[0046] Step 1.4: Digitize the information confirmation authorization result. Encrypt the information confirmation authorization result, the operator's work ID number, and the facial information to generate an encrypted ASCII string. The digitization of the information confirmation authorization result is shown below:

[0047] a4=f(information confirmation result, face data of the person confirming the information).

[0048] Step 2: Bind the 4 types of information in step 1 to generate a digital RP certificate. Step 2 specifically includes:

[0049] Step 2.1: Generate a unique identifier. The applicant’s personal digital identity serves as the unique identifier of the applicant.

[0050] Step 2.2: Bind application record. Each login record contains the digital identities of four types of information: personal identity (ID number and face information), encrypted digital string of personal dose management system application process approval result, encrypted digital string of WBC monitoring data, and encrypted digital string of information confirmation authorization result.

[0051] Step 2.3: Data encryption. The digital identities of the four pieces of information, namely personal identity (ID number and facial information), personal dose management system application process approval results, whole body counter monitoring data, and information confirmation authorization results, are encrypted and calculated using the elliptic curve (ECC).

[0052] Step 2.4: Generate an encrypted digital RP certificate. The calculation and generation of the digital RP certificate is as follows:

[0053] DigiRP=ECC(a1,a2,a3,a4).

[0054] Step 3: Register the digital identity of the digital RP certificate on the blockchain.

[0055] The digital RP certificate and metadata (including creator, creation date, facial biometric information, whole body counter historical data) generated in step 2 and a unique identifier are registered on the blockchain. This digital RP certificate becomes an immutable and tamper-proof digital asset. At the same time, because it is recorded on the blockchain, through the introduction of the blockchain, the historical information related to the digital RP certificate can only be queried and cannot be modified, making it a reliable way to establish uniqueness and authenticity in the digital field.

[0056] Step 4: The user's facial biometric information is bound to the digital RP certificate, and the digital RP certificate is used by facial scanning.

[0057] In addition, the present invention also provides a computer device, including a memory and a processor, the memory stores computer-readable instructions, and the processor implements the steps of the above-mentioned nuclear power plant digital RP certificate generation method when executing the computer-readable instructions.

[0058] In addition, the present invention also provides a computer-readable storage medium, on which computer-readable instructions are stored, and when the computer-readable instructions are executed, the steps of the above-mentioned method for generating a digital RP certificate for a nuclear power plant are implemented.

[0059] Computer readable media include permanent and non-permanent, removable and non-removable media that can be implemented by any method or technology to store information. Information can be computer readable instructions, data structures, program modules or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, compact disk read-only memory (CD-ROM), digital versatile disk (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices or any other non-transmission media that can be used to store information that can be accessed by a computing device.

[0060] Therefore, the present invention realizes the digitization of personal identity information, the digitization of the approval results of the application process of the personal dose management system, the digitization of the monitoring data of the whole body counter, and the digitization of the information confirmation authorization results. The present invention provides a method for binding a digital RP certificate; a method for registering on the blockchain and generating a unique identification (including historical whole body counter data).

[0061] The present invention includes historical full body counter data and supports built-in query of personal historical full body counter data. The facial biometric information of the user is used as the public key and is used in conjunction with the digital RP certificate.

[0062] The present invention does not need to change the existing physical RP certificate workflow. The application of RP certificates involves almost all personnel who enter the radiation control area, including regular employees, maintenance service providers, contractor employees, various types of staff during overhaul, and staff of government regulatory departments. Once the current work procedures (workflow) are changed, it will affect almost all of the above personnel.

[0063] When the present invention is applied, the existing workflow is not changed, and the advantages are mainly as follows:

[0064] (1) Nuclear power plants can avoid the complexity of reapplying for licenses or undergoing extensive regulatory review (such as an upgrade of the FSAR), and any technical improvements that do not change existing operating procedures are more likely to pass regulatory review;

[0065] (2) Keep the work procedures of various other business departments involved in the RP certificate application unchanged as much as possible; following the existing operating procedures can reduce the risk of human errors in key operations caused by the introduction of new technologies (new procedures) and reduce the potential risk of downtime; this is particularly important for nuclear power plants because the consequences of errors can be very serious;

[0066] (3) The various training systems and simulator systems currently used by the power plant do not require changes to standard operating procedures;

[0067] (4) Maintaining process consistency while introducing technological innovation means that the above-mentioned personnel do not have to spend extra time learning new processes, reducing negative feedback and negative evaluations from users of new technologies and RP management departments, thereby achieving a smooth transition to new technologies.

[0068] The present invention improves the reliability and non-tamperability of radiation dose data related to RP certificates by combining digital encryption technology with blockchain technology.

[0069] Through blockchain technology, the present invention can directly query historical dosage data through RP certificate number and personnel identity information, increase the ways to obtain personnel dosage information, and greatly improve the convenience of obtaining historical data.

[0070] The key links of the present invention reduce the manual intervention items, and systematically reduce the risks caused by human errors in the entire certificate application process.

[0071] The key links of the present invention are all completed automatically by the system, and the defects of the current certificate application process, such as long processing time and low work efficiency, can be overcome.

[0072] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
