Description
Technical Field
The invention belongs to the technical field of computer aided drawing, and relates to a method for automatically generating a cross-functional partition signal list by software.
Background
The nuclear power plant instrument control system is divided into a protection system and a control system. The nuclear power plant design requires that the protection system and the control system must be separated from each other to avoid interconnection, or that proper functional independence be employed to prevent interference between the two. Thus if a signal is shared between the protection system and the control system, appropriate isolation measures need to be ensured and the signal system must determine the security classification in terms of a high-level system.
The functional partitions are divided into a plurality of functional partitions, and the functional partitions are specially designed for guaranteeing the safety of the nuclear power plant according to a diversity principle, a redundancy design principle and a longitudinal defense design principle. Therefore, the nuclear power plant instrumentation control system design covers a variety of functional partitions, such as a 1E-level shutdown safety channel 1 functional partition represented by 1E/IPS/IP, an NC-level A-column functional partition represented by NC/IPP/A, a NCS-level post-accident cabinet A-column functional partition represented by NCS/SA/A, a NCS-level DAS dedicated cabinet represented by NCS/DAS, and the like.
Functional partitioning is represented on a design drawing of the instrument control system, a partition line (such as a dash-dot line) is needed to distinguish blocks, and blocks in different functional partitions represent that the block functions are realized by a cabinet of the functional partition. The signals of different functional partitions are exchanged, and according to the design principle of the nuclear power plant instrument control system, the exchanged signals can be sent to the target cabinet position through the isolating device. The isolation device is represented on the drawing as a special block connected with 2 functional partitions, and its own partition should be in a higher-level functional partition. For the exchanged signals, after passing through the isolation block/the isolation distribution block (the isolation distribution block is a special block, the function level of the functions/signals changes after passing through the isolation distribution block, and the signals after the isolation distribution must be sent to another cabinet in the implementation of the instrument control function), the functional partition changes. The isolation blocks/isolation allocation blocks are drawn on the drawing in the high-level functional partitions.
Signals crossing functional partitions need to be listed one by one to count the number of signals required to pass through the isolation devices in the whole nuclear power plant project, so that the scale of different isolation devices is estimated, but finished product drawing software of the instrument control system (or other complete set of design platform software containing drawing of the instrument control system) on the market cannot provide the function.
Disclosure of Invention
The invention aims to provide a method for automatically generating a cross-functional partition signal list by software, which can automatically generate the cross-functional partition signal list in a design drawing of a system of an instrument through computer aided drawing software.
In order to achieve the purpose, in a basic implementation mode, the invention provides a method for automatically generating a cross-functional partition signal list by software, wherein the method automatically generates the cross-functional partition signal list in a nuclear power plant instrument control system design diagram by computer aided drawing software and sequentially comprises the following steps of:

Detailed Description
The following describes the embodiments of the present invention further with reference to the drawings.
An exemplary process flow of the method for automatically generating a cross-functional partition signal list by software of the present invention is shown in fig. 1, which automatically generates a cross-functional partition signal list in a design drawing of a system of instruments through computer-aided drawing software (such as ACP1000FD-SAMA drawing automation design software developed and commercially available by the company of china nuclear power engineering, inc.) comprising the following steps.
(1) Defining the isolation block/isolation allocation block as a standard mold block and defining its input/output roll name
The isolation blocks/isolation allocation blocks are defined as standard mold tiles (as shown in fig. 2) and their input/output point names are defined. IN FIG. 2, 8 isolation/distribution modules are shown, the isolation blocks are single-input, single-output types (e.g., isolation_connect), and only have one input point IN1 and one output point OUT1; the isolation distribution block is of a single input and multiple output type (iso & split_contact) and comprises 1 input point IN1 and 5 output points (OUT 1/2/3/4/5); the input/output signal characteristics of the isolated signals are the same (a block corresponds to a block, a contact corresponds to a fault contact), but the functional classification is different. The tile input/output connection points are arranged in a left-in right-out/up-in and down-out manner. Considering that the signal characteristics of the isolation performed by the isolation blocks/the isolation distribution blocks are different, the isolation blocks/the isolation distribution blocks each include 4 types, i.e., iso & split_block, isolation_block, iso & split_float, isolation_float, iso & split_contact, isolation_contact, iso & split_analog, isolation_analog, respectively. Isolation blocks (isolation) are used to isolate a single signal, while isolation distribution blocks (iso & split) are used to isolate and distribute the same source signal to different functional partitions.
(2) Defining and entering parameter information of isolation blocks/isolation distribution blocks
The definition of the isolation block/isolation allocation block parameter information is shown in fig. 3. Each isolation block/isolation allocation block has a parameter of 'figure number' and is information automatically filled in by software. Each connection point contains 4 parameters, namely "connection tile ID", "signal type", "connection tile name", "connection tile functional partition". After the signals pass through the isolation block/the isolation distribution block, the functional partition is changed, the isolation block/the isolation distribution block is drawn in the high-level instrument control partition on the drawing surface, and the functional partition information of the connection point of the isolation block/the isolation distribution block is manually defined and cannot be automatically generated, so that a parameter of 'connecting the functional partition of the image block' is manually filled by a plotter.
(3) Drawing of pictures
When drawing the instrument control drawing, the plotter first needs to drag the die block from the die library to the drawing area. However, since the types of signals that need to be isolated are different, the types of isolation blocks/isolation distribution blocks are numerous. If the processing is not performed by a software method, 4 die blocks with basically the same appearance and different connection point definition types/block names are only present in the die gallery, and a plotter can find the die selection difficult. In view of the simplicity of the mold gallery selection area and the ease of use, the present invention contemplates a pop-up window-spacer selection window as shown in fig. 4. The plotter drags the tile into the drawing area and the software pops up a window so that the isolation signal type is selected to obtain the isolation block mold tile. Thus, the mould gallery area has only 2 isolation type blocks, and is simple and clear.
(4) Storing the isolation blocks/isolation allocation blocks to a database and automatically exporting by software a list of cross-functional partition signals
The data patterns stored to the database by the isolation block/isolation allocation block are shown in table 1. The principle of software automatic export of cross-functional partition signal list is: screening all isolation blocks/isolation distribution blocks in the database, and outputting information stored in the database into a pattern shown in table 2 aiming at the isolation blocks; for the isolated allocation blocks, the information stored in the database is output as a pattern shown in table 3. Thus, the cross-functional partition signal list can be automatically derived. The user can clearly see where the signal from which block of the graph is passed through to convert the signal into what functional partition.
