Description

Technical Field

[0001] This invention relates to the field of intelligent building technology, and in particular to a modeling method for intelligent building systems based on extended SysML. Background Technology

[0002] Building intelligent systems generally consist of business subsystems such as equipment monitoring, security, and fire alarm. Among them, the equipment monitoring subsystem can be further divided into subsystems such as environmental monitoring, power monitoring, and water supply and drainage monitoring; the security subsystem can be divided into subsystems such as video surveillance, intrusion alarm, access control, and patrol; and the fire alarm subsystem can be divided into subsystems such as fire alarm, fire linkage, and public address. Based on the research and development experience of complex building intelligent systems, in the early stages of system development, it is necessary to design the structural characteristics and behavioral features of the building intelligent system in detail. Generally, the following specific modeling requirements need to be met: First, a detailed design of the structural composition of each business subsystem and subsystem of the building intelligent system; Second, to facilitate the design of the measurement and control logic of each subsystem, a detailed description of the composition of the primary equipment connected to each subsystem is also required, namely the structural composition of the ventilation and air conditioning system, power supply and distribution system, and water supply and drainage system; Third, a detailed description of the status attributes of important equipment (including primary equipment and low-voltage equipment) of the building intelligent system, for example, the power transformer needs to monitor the three-phase core temperature; Fourth, a detailed design of the connection relationships and interface attributes of equipment in each business system, for example, the connection relationships of each equipment in the power supply and distribution system, power supply guarantee relationships, and communication interfaces between each sensor and controller; Fifth, a detailed design of the interactive behaviors between different business subsystems, between subsystems and equipment, and between equipment in the building intelligent system, for example, the linkage relationship between the fire alarm system and other subsystems when handling fires, the linkage and interaction relationships between various equipment, and the state change process of each equipment.

[0003] However, in recent years, with the application of technologies such as cloud computing, the Internet of Things, and edge computing, building intelligent systems have become increasingly powerful, their structures larger, and their operational logic more complex. This rapid increase in scale and complexity presents numerous challenges to modeling and design: First, the systems involve multiple fields and disciplines, creating a professional "gap" in modeling and design. General system modelers often struggle to accurately depict the technical characteristics of HVAC, water supply and drainage, and power distribution systems, while building maintenance personnel are unfamiliar with software requirements analysis and modeling design methods and tools. Second, building intelligent systems are complex systems that deeply integrate the information and physical domains. Information system software closely collaborates with front-end sensors, controllers, and other hardware, as well as electromechanical equipment such as pumps and fans. Traditional software and information system modeling methods such as UML and SysML offer limited support, making it difficult to characterize the hardware composition and structural characteristics of building intelligent systems.

[0062] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0063] Figure 1 This diagram illustrates a flowchart of an embodiment of a building intelligent system modeling method based on extended SysML provided by the present invention. Figure 1 As shown, it includes the following steps:

[0064] S1. Extend the module definition diagram in SysML to obtain the module definition diagram of the building intelligent system.

[0065] The building intelligent system module definition diagram is used to construct the structural model of the building intelligent system. The building intelligent system module definition diagram includes: a set of building intelligent system modules, a set of building intelligent system relationships, a set of building intelligent system structural features, a set of building intelligent system behavioral characteristics, and a set of building intelligent system value types. Based on the building equipment, equipment attributes, equipment characteristics, and inter-equipment relationships corresponding to the building intelligent system, the module definition diagram in SysML is extended to obtain the building intelligent system module set, building intelligent system relationship set, building intelligent system structural feature set, building intelligent system behavioral characteristic set, and building intelligent system value type set.

[0066] In this embodiment, the Building Intelligentized System Block Definition Diagram (BIS-BDD) is a quintuple, including: a set of building intelligentized system modules, a set of building intelligentized system relationships, a set of building intelligentized system structural features, a set of building intelligentized system behavioral characteristics, and a set of building intelligentized system value types. BIS-BDD = BIS R, S C B C V T >. Specifically:

[0067] 1)B BIS ​This refers to a collection of Building Intelligent System Blocks (BIS Blocks), which include: fans, dehumidifiers, heaters, humidifiers, air conditioners, water pumps, electric valves, water treatment equipment, transformers, low-voltage power distribution equipment, high-voltage power distribution equipment, DC power supplies, diesel generator sets, reactive power compensation cabinets, servers, switches, sensors, controllers, actuators, uninterruptible power supplies, and edge computing nodes. In short, B... BIS = {Fan, Dehumidifier, Heater, Humidifier, Air Conditioner, Pump, Electric Valve, Water Treatment Equipment, Transformer, LV Switchgear, HV Switchgear, DC Panels, Diesel Generators, StaticVar Generator, Server, Switch, Sensor, Controller, Actuator, UPS, Edge ComputingNode}. The BIS Block primarily represents common equipment in building intelligence systems. Figure 2The equipment commonly used in the various business subsystems of intelligent building systems can be divided into two main categories: primary electromechanical equipment and information equipment. Primary electromechanical equipment can be further divided into three categories: environmental supply equipment, power supply equipment, and water supply equipment. Therefore, BIS Blocks are divided into four categories: (a) Environmental protection equipment, including fans, dehumidifiers, heaters, humidifiers, and air conditioners; (b) Water supply and drainage protection equipment, including pumps, electric valves, and water treatment equipment; (c) Power protection equipment, including transformers, low-voltage switchgear, high-voltage switchgear, DC panels, diesel generators, and static var generators; and (d) Information technology equipment, including servers, switches, sensors, controllers, actuators, uninterruptible power supplies (UPS), and edge computing nodes. Figure 3 As shown, for each module b∈B BIS b is constructed by extending the blocks in SysML and is represented by the symbol <<>>.

The BIS relationship set includes: generalization, part association, reference association, and dependency; R = {Generalization, Part Association, Reference Association, Dependency}. Generalization represents inheritance relationships between modules, allowing the creation of subtypes; for example, a fan can be generalized into cleanroom fans, filter fans, etc. Part association represents structural decomposition within the BIS; for example, an environmental monitoring subsystem can be decomposed into temperature and humidity sensors, carbon dioxide concentration sensors, DDC controllers, etc. Reference association indicates that an attribute of one module needs to reference attributes of other modules; for example, the oil temperature attribute of a diesel generator module needs to reference the attribute of a related oil temperature sensor. Dependency indicates that one module depends on the definition of another module; for example, ... Figure 4 As shown, the starting of a diesel generator set depends on the coordinated operation of the water pump cooling water and the fan exhaust, which can be represented by a dependency relationship.

The BIS set includes: component attribute set, reference attribute set, value attribute set, constraint attribute set, and port set. Structural characteristics are divided into five categories, namely S... C =S C1 ∪S R ∪S V ∪S C2 ∪S P , of which S C1 This is a collection of component attributes, representing the modules of a building's intelligent system that are composed of several devices. It typically refers to the physical composition relationships. Figure 5 Taking the Fire Alarm System shown as an example, it consists of several devices, with "parts" representing the attributes of the components; S RThis is a collection of reference attributes, representing a "need" relationship, indicating that there is some connection between the two. For example, a fire alarm system needs cameras in a video surveillance system to assist in fire alarm judgment; S V This is a collection of value attributes, typically assigned a number, but can also be a boolean value or a string. For example, "temperature" refers to the cable temperature measured by a temperature sensing cable detector. C2 This represents a set of constraint attributes, typically indicating a mathematical relationship. It uses a series of value attributes to represent the constraint. For example, the temperature threshold constraint for temperature sensing cables is temperature ≥ SetValue. P Ports represent a set of ports, which can represent any type of interaction point required for modeling. They can be either hardware or software objects. For example, the communication interface of the Temperature Sensing Cables is a Smart Interface II.

[0070] 4)B C This represents the set of behavioral characteristics of a building intelligent system (BIS), which represents a series of behaviors that a building intelligent system module (BIS Block) can perform.

[0071] 5)V T This refers to the set of value types in a building intelligence system (BIS). The BIS value type set includes: a professional value type set, a structural value type set, and an enumerated value type set. In a building intelligence system, value types are defined as three types, namely V... T =V P ∪V S ∪V E Among them, V P Indicates the Professional ValueType, such as Figure 6 As shown, it is constructed by extending the SysML real number type Real, V P This mainly defines the commonly used numerical types of various measurement parameters in building intelligent systems, such as temperature values ​​(°C), relative humidity values ​​(%), pressure values ​​(MPa), and volume values ​​(m³). 3 Flow value type m 3 / h, liquid level type m, gas concentration type ppm, rotation speed type r / min, voltage type V, current type A, frequency type Hz, power type kW; professional value types are constructed by extending SysML real number type Real; V S This is a collection of Structure Value Types, typically possessing multiple value attributes. For example, the operating status of a device can be represented by 1 (normal) and 0 (fault). E This indicates an enumerated value type. For example, a three-color audible and visual alarm (a generalized instance of Actuator) outputs three colors: red, yellow, and green to represent three different alarm conditions.

[0072] S2. Expand the internal module diagram in SysML to obtain the internal module diagram of the building intelligent system.

P BIS This is used to represent the connection interface between the controller and the front-end sensors and actuators in a building intelligence system. For example, in an environmental monitoring system, the front-end analog sensors and the DDC controller are connected using an AI interface.
