[0002] A distributed control system is a new generation of instrument control system based on microprocessors, which adopts the design principle of decentralized control function, centralized display operation, and comprehensive coordination. It is also called DCS (Distributed Control System). As a general process control platform, the distributed control system plays a key role in the operation of industrial process systems. Currently, the common application needs are that when power plant operators need to switch from monitoring pictures, alarm systems and other software to corresponding logic diagrams for logic analysis. Taking a 1000MW unit DCS as an example, there are about 15,000 to 20,000 tag names for this type of unit. When an accident occurs in the power plant, it is difficult for maintenance personnel to quickly locate the control logic configuration of the equipment through detailed tag names. In addition, for accident analysis, when a device moves abnormally, a comprehensive logic analysis of the entire device system is often required. For example, when a primary fan fails, a comprehensive analysis of the drive motor, moving blade adjustment, and lubricating oil system of the primary fan is often required. However, when designing the control logic of the controlled device, in order to improve the reliability of the control system, the above-mentioned subsystems are dispersed in different control units, which affects the quick positioning of the control logic.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0018] A DCS control logic fast automatic positioning method is provided for the present application. Figure 1 The method mainly includes the following steps: Step S1, the system finds the corresponding algorithm module according to the tag name or the description information of the algorithm module input by the user.

[0019] Step S2, the algorithm module is found according to the algorithm module, the controller where the algorithm module is located is found, all configuration page information is read from the controller, and the algorithm module graphics of each algorithm module and the corresponding reference relationship in the configuration page view are drawn.

[0020] Step S3, all algorithm module information in the configuration page is read, and the configuration page logic diagram of each algorithm module and the corresponding reference relationship in the configuration page view is drawn. Based on the configuration page logic diagram, the algorithm module is automatically positioned according to the input matching query algorithm module.

[0022] Specifically, in step S1, the tag name of the algorithm module is the key of the hash table, denoted as tagname, and the description information of the algorithm module is the value of the hash table, denoted as description value. The set of the tag name and the description information of the algorithm module in all controllers is established, and the tag name and the description information of all algorithm modules are stored in the key-value pair in the hash table hash<tagname, description>.

[0023] The system searches for the corresponding algorithm module from the hash table according to the input tag name or description information of the algorithm module, and uses the following method: Traverse the hash table, take out each tagname or description value in the hash table, and perform string fuzzy matching with the query condition input by the system. The corresponding algorithm module is found through the tag name or description information of the algorithm module.

[0024] As shown in Figure 2 In step S2, the controller where the algorithm module is located is found according to the algorithm module, and all configuration page information is read from the controller, including the following contents: According to the tag name tagname of the algorithm module, the controller where the algorithm module is located is found, and the handle value svc_handle of the algorithm module and the handle value svc_paren_thandle of the configuration page where the algorithm module is located are read from the controller where the algorithm module is located. All configuration page information is read from the controller where the algorithm module is located, and each configuration page information is stored in a structure Diagram. The structure Diagram is defined as follows: diagram_tagname is the tag name of the configuration page; diagram_description is the description of the configuration page; diagram_handle is the handle number of the configuration page; diagram_parent_handle is the handle value of the parent node to which the configuration page belongs; All read configuration page information is saved in the hash table diagram_hash<diagram_handle, diagram>, and the key value of the hash table is diagram_handle, and the value of the hash table is the structure Diagram object.

[0025] Based on the above reading all configuration page information from the algorithm module in the controller, draw configuration page view of each algorithm module and the corresponding reference relationship algorithm module graph element, the process is as follows: Traverse the hash table diagram_hash<diagram_handle, diagram>, take out the i-th hash table in the configuration page handle number diagram_hash[i]->diagram_handle, judge whether the algorithm module corresponding to the configuration page diagram_hash[i]->diagram and the handle value svc_parent_handle of the configuration page where the algorithm module is located (according to the reference information to judge whether the algorithm module is in the same controller) is the same, if the same, find the input algorithm module corresponding to the configuration page diagram_hash[i]->diagram, draw the configuration page logic diagram; If not, read all algorithm modules and algorithm module pin reference information in the algorithm module corresponding to the configuration page diagram_hash[i]->diagram from the controller, according to the algorithm module and the algorithm module pin reference information read, draw the algorithm module graph element of each algorithm module and the mutual reference relationship between the algorithm modules in the configuration page view, the algorithm module graph element is the graph element with algorithm module type in the configuration page view, which is composed of algorithm module pin connection and algorithm module pin label.

[0026] In step S3, read all algorithm module information in the configuration page, including: Step S31, read all algorithm module information in the configuration page from the controller, represented by structure Block, display the coordinates of algorithm module, the type of algorithm module in the visual configuration page view; According to the algorithm module information read, create the representation of algorithm module graph element through the type of algorithm module svc_type, represented by Block_Element.

[0027] Use the x-axis coordinate value svc_x of the algorithm module and the y-axis coordinate value svc_y of the algorithm module to represent the coordinates of the algorithm module graph element Block_Element in the configuration page view, and display the label name svc_tagname information of the algorithm module in the algorithm module graph element.

[0028] Use hash table Block_Hash<svc_handle, Block> to store all algorithm module information in a configuration page, and find the algorithm module information according to the handle number svc_handle of the algorithm module; The algorithm module information and the algorithm module graph element information are stored in a hash table Block_Element_Hash<Block, Element>, and the algorithm module graph element is searched according to the algorithm module information.

[0029] In step S32, the reference information of all algorithm module input and output pins in the configuration page is read. The reference information of each algorithm module pin is represented by a structure body Attr_ref, and the structure body Attr_ref is defined as follows: svc_handle represents the handle number of the algorithm module; svc_parent_handle represents the handle of the configuration page to which the algorithm module belongs; attr_name represents the attribute name of the algorithm module; List<Svc_refinfo> represents the reference information of the algorithm module pin; The reference information of the algorithm module pin is stored in a linked list. If the algorithm module pin has no reference information, the linked list is empty. The reference information of the algorithm module pin is represented by a structure body Svc_refinfo, and the structure body Svc_refinfo is defined as follows: ref_svc_handle represents the handle of the algorithm module represented by the reference; ref_svc_parent represents the handle of the configuration page in which the algorithm module represented by the reference is located; ref_string represents the reference information of the algorithm module pin; The reference information of all algorithm module pins in the configuration page is stored in a linked list Attr_List<Attr_ref>.

[0030] In step S33, based on the above steps, the configuration page logical diagram of each algorithm module and the corresponding reference relationship in the configuration page view is drawn, and the process is as follows: First, the linked list Attr_List<Attr_ref> is traversed, and the i-th structure body Attr_ref object in the linked list is taken out, where i is in the range of 0 to the number M of Attr_ref contained in the linked list Attr_List<Attr_ref>, and is marked as Attr_List[i]. According to Attr_List[i], the handle value Attr_List[i]->svc_handle of the algorithm module corresponding to the algorithm module pin, the handle Attr_List[i]->svc_parent_handle of the configuration page in which the algorithm module is located, and the reference information Attr_List[i]->Ref_List<Svc_refinfo> of the algorithm module pin are taken out.

[0031] Secondly, traverse the reference information of the algorithm module pin in the linked list Attr_List[i]->Ref_List<Svc_ref_info> and take out the jth structure Svc_ref_info object in the linked list, which is represented by Attr_List[i]->Ref_List[j], where j ranges from 0 to the number N of the structure Svc_ref_info contained in the linked list Attr_List[i]->Ref_List<Svc_ref_info>; Traverse the linked list Attr_List[i]->Ref_List[j] and take out the handle Attr_List[i]->Ref_List[j]->ref_svc_parent of the configuration page where the algorithm module represented by the jth reference is located and the handle Attr_List[i]->Ref_List[j]->ref_svc_handle of the algorithm module represented by the jth reference.

[0032] Finally, judge whether the handle Attr_List[i]->Ref_List[j]->ref_svc_parent of the algorithm module represented by the jth reference is the same as the handle Attr_List[i]->svc_parent_handle of the configuration page where the algorithm module is located; If the two values are the same, it means that the algorithm module and the algorithm module corresponding to the algorithm module pin are in the same configuration page. According to the handle Attr_List[i]->Ref_List[j]->ref_svc_handle of the algorithm module represented by the reference, the corresponding algorithm module information is found in the hash table Block_Hash<svc_handle, Block>, and the corresponding algorithm module graph element is found in the hash table Block_Element_Hash. In the configuration page, the two algorithm modules are connected by a wire. If the two values are different, it indicates that the algorithm module and the algorithm module pin correspond to algorithm modules in different configuration pages. The algorithm module information is found in the hash table Block_Hash<svc_handle, Block> using the algorithm module Attr_List[i]->svc_handle, and the algorithm module primitive is found in the hash table Block_Element_Hash according to the algorithm module information. A reference tag containing reference information is drawn at the pin in the algorithm module primitive, and the reference tag contains reference information Attr_List[i]->Ref_List[j]->ref_string. The reference tag indicates that the algorithm module of the current configuration page references the algorithm module of another configuration page, and on the other hand, the reference tag can jump to the group where the algorithm module represented by the reference tag is located.

[0033] Based on the configuration page logical diagram, the algorithm module matching the input query is automatically located, and the process includes: According to the input matching query algorithm module, the algorithm module primitive is matched and queried in the configuration page logical diagram. The Attr_List[i]->svc_handle obtained by traversal is matched with the handle value svc_handle of the input query algorithm module. If the two values are equal, the algorithm module primitive represented by Attr_List[i]->svc_handle is the algorithm module primitive queried by the input, which is selected and framed in the configuration page logical diagram. The algorithm module is automatically located, thereby realizing fast and automatic location of the control logic.

[0034] Step S4, according to the algorithm module reference information selected in the configuration page logical diagram, automatically jump to the configuration page where the referenced algorithm module is located, and automatically generate a jump logical diagram in the configuration page. The algorithm module corresponding to the reference information is selected in the jump logical diagram, and the process is as follows: Click the reference tag containing reference information drawn at the pin in the algorithm module primitive to jump to the configuration page where the algorithm module displayed in the reference tag is located, and draw a jump logical diagram; Click the tag of the algorithm module pin in the jump logical diagram to obtain the current algorithm module reference information Svc_ref_info, and according to the reference information Svc_ref_info, reference the configuration page handle ref_svc_parent where the algorithm module is located; According to the configuration page handle ref_svc_parent where the algorithm module is located, the configuration page is matched in the hash table diagram_hash, the hash table diagram_hash is traversed, the i-th configuration page handle number diagram_hash[i]->diagram_handle of the hash table diagram_hash is taken out, and it is judged whether the i-th configuration page handle number diagram_hash[i]->diagram_handle is same as the configuration page handle ref_svc_parent where the algorithm module is located; If the two values are same, the configuration page information does not need to be read, that is, the step of automatically positioning the algorithm module is executed from step S33; if the two values are different, the configuration page information needs to be read, that is, the step of automatically positioning the algorithm module is executed from step S32.

[0035] The method provided in the application can also realize the automatic positioning of the algorithm module by drawing the configuration page tree diagram node, and the process is as follows: The system draws the configuration page tree diagram node according to reading all the configuration page information from the controller, and the specific steps are as follows: The configuration page hash table diagram_hash<diagram_handle, Diagram> in the controller is traversed, the configuration page handle value diagram_handle in the i-th configuration page Diagram object in the hash table is taken out, and the value range of i is from 0 to the number N-1 of the configuration page Diagram elements contained in the hash table; The configuration page hash table diagram_hash in the controller is traversed, the handle value diagram_parent_handle of the parent node to which the j-th configuration page Diagram object in the hash table belongs is taken out, the value range of j is from i+1 to N, the Diagram set in which the handle value diagram_parent_handle of the parent node to which the configuration page belongs is same as the configuration page handle value diagram_handle in all nodes is found, and the Diagram set is used as List <diagram>The node is displayed as a child node of the i-th node, and the relationship between the parent and child nodes is displayed by a configuration page tree diagram; The precondition of the fast positioning is to draw the logic diagram in which the function block is located, therefore the above steps create the configuration page tree diagram node, by clicking the configuration page tree diagram node, the configuration page logic diagram is drawn by using the same method as that of drawing the configuration page logic diagram in the above-mentioned algorithm module positioning mode, and the algorithm module is positioned by the configuration page logic diagram, since the method steps of drawing the configuration page logic diagram in the algorithm module positioning mode are the same, they are not described here again.

[0036] It should be noted that the parts not involved in the present application are the same as or can be realized by using the prior art. The above description is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.< / diagram> < / diagram>
