[0074] Embodiment 2: Hualong One nuclear safety-level DCS hard logic design and inspection system, which is used to implement the Hualong One nuclear safety-level DCS hard logic design and inspection method recorded in Embodiment 1, such as Figure 2 As shown, it includes analysis module, algorithm library, database, design module, QR generator, assembly module and inspection module.
[0075] Among them, the analysis module is used to allocate the design input into emergency shutdown function, containment isolation function, safety spray function, safety injection function, main feedwater isolation, main steam isolation, and auxiliary feedwater startup according to the hard logic functions of the Hualong One nuclear power plant; the algorithm library is used to abstract the algorithm into combinable function block particles according to the basic design principles of the hard logic in the Hualong One nuclear power plant, and combine the function block particles to form the control logic of the corresponding nuclear power plant according to the actual design requirements of different nuclear power plants; the database is used to record the key information, logic block diagram and design summary information of the design process; the design module is used to implement electrical design work and component space layout; the QR generator is used to generate QR for verification by recording the key information of the design process; the assembly module is used to carry out assembly activities according to the design summary information; the inspection module is used to inspect the assembly activities according to the design summary information and QR.

Specifically, the logic principle design module is used to carry out detailed electrical design work down to the level of devices and their connection relationships based on the logic block diagram; the auxiliary design module is used to complete the electrical design work of cabinet-level power supply and instrumentation and control alarms; the space layout design module designs the spatial layout of components in the DCS cabinet based on the results of the electrical design work; among them, the design drawing verification information after the spatial layout of components is completed is stored in the key information for forming QR and for inspection.

[0079] The basic design input framework is shown in the figure Figure 3 The possible values of each dimension are shown in Table 1. The attributes of each dimension are combined to complete the specific design input analysis. The attribute parameters of each dimension are the content sent by the analysis module to the summary unit.

[0081]

The relationship requirements of A1-A9 are mapped to the basic logic schematic diagram to obtain the logic schematic diagram, where A1-A9 are reflected in the marked schematics in the figure.
[0083] In the present invention, the power supply design includes aspects such as power supply voltage, redundant power supply, and powered equipment, and attributes such as current type need to be set separately, as shown in Table 2.
[0084] Table 2 Power supply design parameters
[0085]
[0086]
[0087] The instrumentation alarm design includes air switch trip alarm, cabinet high temperature alarm, cabinet door open alarm, etc., which need to set parameters such as switch quantity, temperature control limit, signal transmission / self-alarm, etc., as shown in Table 3 and Figure 4 shown.
[0088] Table 3 Instrumentation and control alarm design parameters
[0089]
[0090] The space layout design module divides the cabinet installation space into front view (F area), rear view (R area), left view (A area), and right view (B area), and numbers the installation areas from top to bottom according to independent installation panels, such as F01.
[0091] Among them, the application of QR code can effectively record the key information of the entire design process and effectively and conveniently verify the above information in the inspection stage. The QR generator receives summary data, including design input baseline information, algorithm library version, analysis module and design module verification information MD5.
[0092] like Figure 5 As shown, the QR code generator includes a data analysis and processing module, a QR code generation module, and a QR code printing module.
[0093] The data analysis and processing module includes a data analysis module and a data processing module. Among them, the data analysis module receives summary information, sorts the information, and calculates the length. The data processing module organizes the above information into a standard string and sends it to the QR code generation module. The QR code generation module includes a QR code generation module and a QR code storage and search module. The QR code generation module generates a two-dimensional code and stores it in the QR code storage and search module. The QR code storage and search module classifies and stores the generated QR codes in the system for easy search and search. The QR code printing module realizes the physical printing function of the QR code, and can select the printing size, color, etc. according to actual needs, and provide the QR code for the inspection module.
[0094] Example 3: Taking a typical Hualong One nuclear safety-level DCS as an example, some of its design inputs are as follows: Figure 6 shown.
[0095] The analysis module analyzes the above design input into the form shown in Table 4, taking the containment isolation phase A logic in column B as an example, Figure 7 shown.
[0096] Table 4 Design input analysis form
[0097]
[0098] like Figure 8 As shown in the figure, in terms of auxiliary function design, C1, C2, and C3 in the figure respectively mark the impact of the three design parameters of the number of air switches, temperature alarm limit, and alarm display type on the detailed electrical design. Taking 12-way air switches, 45℃ alarm limit, and alarm display as door open alarm as an example, the design drawings are obtained, as shown in Fig. 9 shown.
[0099] The summary unit collects key information from the analysis module and the design module to form a summary. The analysis module provides the design input baseline version B, the algorithm library version 4.0-9, and the attribute value column data content of the above parameter table. The design module provides the attribute value column data content of the above parameter table to form a summary. The summary is processed into a standard string by the data analysis processing module and sent to the QR code generation module for storage and printing for the verification module.
[0100] In this embodiment, the summary information includes: B; 4.0-9; E35...93A (MD5 code of the analysis module parameter table); C49...6B7 (MD5 code of the design module parameter table), and the above character string generates a QR code.
[0101] Set the front view of the cabinet as F zone, the first installation plate as F01 zone, and number them from top to bottom. Similarly, set the rear view of the cabinet as R zone. According to the space design, arrange the safety injection logic in F03-F06 zone, the containment isolation phase A logic device in F07-F09 zone, and the containment isolation phase B in R03-R06 zone.
[0102] After the design is completed, the design data forms an assembly database, including equipment information, parameter information, connection information, marking information, and installation layout information. The design of the containment isolation phase A series B of a typical Hualong One nuclear power plant forms the following database, with only partial information as an example, as shown in Table 5.
[0103] Table 5 Partial example of assembly database
[0104]
[0105] The assembly module carries out assembly work according to the data in the assembly database.
[0106] The inspection module first uses QR to check whether the design input baseline version and algorithm library version are correct, then checks whether the design drawing is consistent with the parameter table of the QR code, and then checks whether the assembly wiring is consistent with the design drawing to complete the inspection work.
[0107] During the inspection, the inspector scans the QR code and obtains the string "B; 4.0-9; E35…93A; C49…6B7". The first semicolon is the input baseline version B, followed by the algorithm library version 4.0-9, the analysis module parameter table MD5 code E35…93A, and finally the design module parameter table MD5 code C49…6B7. Compare the MD5 code of the design file to ensure that the design file version is correct and has not been tampered with.
[0108] Working principle: The present invention constructs a method of input analysis-data integration-electrical design. At the same time, based on the key information summary of each link, it uses QR code (QR) technology to carry out strict design process control, prevent version management confusion, and realize anti-tampering function.
