Description

Technical Field

[0001] The invention relates to the technical field of fire fighting, in particular to a graphical programming method for a fire fighting linkage system. Background Art

[0002] The fire linkage system is an indispensable and important part of modern buildings. It is used to automatically control various fire fighting equipment to work together when a fire occurs to minimize the losses caused by the fire. However, the traditional fire linkage system has some problems and challenges in programming.

[0003] First of all, the traditional fire linkage system usually adopts text programming, which requires programmers to have certain professional knowledge and skills. Since text programming is more complex, prone to errors and difficult to debug, it brings a lot of workload and pressure to programmers.

[0004] Secondly, the linkage logic of the fire linkage system is usually complex, involving the relationship between multiple fire protection equipment. In the traditional text programming method, programmers need to manually write a large amount of logic code, which is not only inefficient but also prone to errors. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a graphical programming method applied to the fire linkage system. Programming is performed through a graphical interface, so that programmers can implement the fire linkage program through constructed programming elements according to the project fire linkage requirements, and then realize the linkage of the fire linkage system. In addition, the graphical programming method also has partitions and custom hierarchical labels for fire equipment types and component units, which makes it easy for programmers to check for deficiencies and reduce fault tolerance. Programming is performed through a graphical interface, so that programmers can intuitively construct the fire linkage program, avoiding complex text programming and improving programming efficiency and accuracy. At the same time, because the graphical interface is easy to understand and operate, the technical requirements for programmers are also reduced.

[0006] In order to solve the above technical problems, the present invention provides a graphical programming method applied to a fire linkage system, wherein the graphical programming system is based on graphical programming software and comprises the following steps:

[0007] S1: Establish the following programming elements in the tool interface of the graphical programming software, including: program elements, providing linkage of the same rules between elements; program elements are automatically divided into conditional elements and action elements, the conditional elements are used to input sub-elements and logical relationships, and the action elements are used to input linkage actions; custom type elements: set fire equipment types and components; expression elements: used to define and reuse defined logical expressions; partition elements: used to define physical location fire partitions or logical groupings of multiple fire facilities, and list hierarchical sub-partitions, and partition setting programming labels; entity elements: provide specified fire facilities, fire facility components or entities in partitions that have occurred specified events; virtual partition elements: provide wildcard conditions for defining partition dimensions; virtual host elements, used to define wildcard conditions and corresponding actions for host dimensions;

[0008] S2: According to the multiple project linkage requirements compiled by the fire protection project, the physical fire protection facilities, fire protection equipment components and fire protection zones required to be configured in each linkage requirement are input into the custom type element one by one for custom setting, and are partitioned in the partition element;

[0009] S3: According to each linkage requirement described in the step, first determine which type of entity element, virtual element or virtual host element it belongs to; according to the selected element type, drag the custom type element and partition element configured in step S2 to the corresponding automatically generated conditional element and action element; if there is a defined expression element, directly input it into the conditional element.

[0010] A further optimization scheme is: in step S2, if the program element required by the linkage is an entity element, the following steps are executed: under the condition element, according to a specific linkage requirement program, several sub-condition elements are defined; the defined fire-fighting facilities, components or partitions are set under the condition element; the defined fire-fighting facilities / component units / partitions are set under the action element.

[0011] A further optimization scheme is as follows: in step S2, if the program element required by the linkage is a virtual partition element, the following steps are executed: define several sub-conditional elements for the conditional element according to the linkage requirement program, set the partition root element under the conditional element, and generate a virtual partition conditional element; and set several sub-conditional elements, set them under the virtual partition conditional element according to the defined custom type elements, and configure the facility types and event types within the partition that meet the conditions; set them under the action element according to the partition root element, and generate a virtual partition action element; set the defined custom type elements under the virtual partition action, and configure the fire protection facility types that meet the execution action.

[0012] A further optimization scheme is: in the steps, a virtual partition action element is generated under the action element according to the partition root element setting, specifically: first, the partition label of the partition element is set to indicate that the partition with this label executes the action; the partition type is set to specify the relationship between the partitions that meet the conditions: current partition, parent partition or adjacent partition.

[0013] A further optimization scheme is: in step S2, if the program element required for linkage is a virtual host element, the following steps are executed: the fire-fighting facility root element is set under the condition element of the virtual host element to generate a virtual host condition element, and under the condition element of the virtual host element, several sub-level conditions are set as needed; the defined custom type element is set to the virtual host condition or sub-level condition, and the corresponding configured fire-fighting facility type and event type are input; the fire-fighting facility root element is set in the action element to generate an action element of the virtual host element; the defined custom type element is set under the action element of the virtual host element.

[0014] A further optimization plan is: the fire-fighting equipment includes but is not limited to: automatic fire alarm system, gas fire extinguishing system, fire door system, emergency lighting and evacuation system, electrical fire system and fire water system.

[0015] A further optimization scheme is as follows: the partition refers to configuring each building, each unit or each floor as a partition, and the hierarchy is building>unit>floor, and the adjacent relationship of each floor is represented by a defined order.

[0016] According to claim 4, the graphical programming method for fire linkage system is characterized in that it supports sub-level partitions to make partitions hierarchical, supports partition setting labels for classifying partitions and programming with labels.

[0017] A further optimization scheme is: the conditional element is used to input sub-elements and the logical relationship is: AND, OR, COUN or Not relationship, COUNT represents the number of conditions that are met, and supports sub-conditional elements.

[0018] Another technical solution disclosed in the present invention is: a computer device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that the processor executes the computer program to implement any one of the graphical programming methods for fire linkage systems claimed in the claims.

[0019] The technical effect of the present invention is that the graphical programming method applied to the fire linkage system disclosed in the present invention is programmed through a graphical interface, so that the programmer first constructs the programming elements according to the project fire linkage requirements, and then constructs the entity program, the partition wildcard program and the host wildcard program. The wildcard program is matched with the fire linkage requirements to realize the writing of the fire linkage program, and then realize the linkage of the fire linkage system. In addition, the programming method of the present invention has the fire equipment type and the component unit has partition and custom hierarchical labels, which makes it easy for programmers to check for deficiencies and reduce the fault tolerance rate.
