本发明属于电力系统实时监控图形界面技术领域，具体涉及一种用于电力实时监控系统的图形界面控制方法。The invention belongs to the technical field of real-time monitoring graphical interfaces of electric power systems, and in particular relates to a graphical interface control method for real-time monitoring systems of electric power.
背景技术Background technique
在电力实时监控系统中，图形用户界面子系统承担着人机交互枢纽的职责。通过图形界面，运行人员可以监视现场设备的实时量测量和开关量，把握系统的运行工况，对现场设备进行控制和调节，还可以查询历史数据以了解特定条件下的系统发展趋势进而辅助分析和决策。这就要求在实时监控图形界面上采用合适形式展示和操作多种来源的不同性质的系统业务数据，将界面上的图形和业务数据对应起来的过程即为图形和业务数据关联。In the power real-time monitoring system, the graphical user interface subsystem assumes the responsibility of the human-computer interaction hub. Through the graphical interface, the operator can monitor the real-time measurement and switching of field equipment, grasp the operating conditions of the system, control and adjust the field equipment, and can also query historical data to understand the system development trend under specific conditions and assist in analysis and decision making. This requires that system business data of different natures from multiple sources be displayed and operated in an appropriate form on the real-time monitoring graphical interface. The process of matching the graphics on the interface with business data is the association between graphics and business data.
业务数据的来源是多样的，有实时数据库、关系型数据库、数据文件或者其他应用系统等，不同数据来源中的业务数据的访问方式和数据格式存在着很大差异。业务数据的性质是各异的，有实时量测量、实时开关量、控制量、历史序列数据之分，不同性质的业务数据有不同的数据属性和不同的动作行为，不同的数据属性又有各自的数据类型和表示形式，因此不同业务性质数据的界面展示和互操作的方式应有所区别。There are various sources of business data, such as real-time databases, relational databases, data files, or other application systems. The access methods and data formats of business data in different data sources are very different. The nature of business data is different, including real-time measurement, real-time switching, control, and historical sequence data. Business data of different natures have different data attributes and different action behaviors, and different data attributes have their own Therefore, the interface display and interoperability methods of different business nature data should be different.
图形界面上会产生界面操作事件，业务数据源或业务数据实例也会产生业务事件，把事件的发送者和接收者关联起来，事件发生时能够根据需要响应处理这些事件，这就构成了系统的动态运行机制的有机组成部分。Interface operation events will be generated on the graphical interface, and business data sources or business data instances will also generate business events. The sender and receiver of the event are associated, and when an event occurs, it can respond and process these events as needed, which constitutes the system. An integral part of the dynamic operating mechanism.
因此，由于业务数据源及数据的巨大差异，经常会出现图形对象和业务数据关联实现起来较为复杂，导致效率低下，无法快速灵活地构建电力实时监控界面的问题。Therefore, due to the huge differences in business data sources and data, it often occurs that the association between graphic objects and business data is complicated to implement, resulting in low efficiency and the inability to quickly and flexibly build a real-time power monitoring interface.

业务数据源种类有：关系型数据库、实时数据库、内存数据、数据文件、其它应用系统等；所述的业务数据类别，根据业务含义可分为量测量、开关量、控制量等，根据时效性可分为实时数据和历史数据。The types of business data sources include: relational database, real-time database, memory data, data files, other application systems, etc.; the business data category can be divided into quantity measurement, switch quantity, control quantity, etc. according to the business meaning; according to the timeliness It can be divided into real-time data and historical data.
业务数据源和业务数据都具有属性、方法和事件信息，是根据具体系统的应用需求选取确定的。业务数据源的属性信息包含数据源名称、访问方式等；业务数据的属性信息更多的则是与其数据类别相关，如量测量具有点号、当前值、采集值、时标、品质值等属性，开关量具有点号、当前状态值、时标、闭锁标志等属性，控制量具有点号、关联量测量、闭锁标志等属性；方法是指业务数据源和业务数据对外提供的动作行为，如数据源的连通、断开，业务数据上的业务处理；事件则是业务数据源和业务数据内部状态改变时的对外通知。Both business data sources and business data have attributes, methods and event information, which are selected and determined according to the application requirements of the specific system.

业务数据适配器模块的作用是对界面系统屏蔽不同业务数据源及业务数据的差异，使前者可以采用统一的方式访问业务数据。它是从实际业务需求出发，在对具体的业务数据源和业务数据进行分析归纳的基础上而实现的。The function of the business data adapter module is to shield the difference between different business data sources and business data from the interface system, so that the former can access business data in a unified way. It starts from actual business needs and is realized on the basis of analyzing and summarizing specific business data sources and business data.
(2)编写界面上每类图形的访问代理：根据界面上每种图形的特点，将其属性、方法和事件信息封装成图形对象访问代理，图形对象访问代理主要与图形对象的种类相关，不会频繁变动。(2) Write the access agent for each type of graphics on the interface: according to the characteristics of each type of graphics on the interface, encapsulate its attributes, methods and event information into a graphic object access proxy. The graphic object access proxy is mainly related to the type of graphic object. Will change frequently.
界面图形种类有直线、折线、弧线、矩形、圆形、扇形、多边形、文字、图片等基本形状，以及由基本图形组合而成的复合形状。The types of interface graphics include basic shapes such as straight lines, polylines, arcs, rectangles, circles, sectors, polygons, text, and pictures, as well as compound shapes composed of basic graphics.
每种界面图形都有属性、方法和事件信息，这些信息由于主要与图形种类相关而保持了相对稳定。图形对象的属性信息包括位置、尺寸、颜色、可见性等；方法信息则主要是对其属性的修改，如移动、放大、缩小、闪烁、显隐；事件信息是由鼠标、键盘等界面操作(包括鼠标点击、鼠标双击、鼠标右键点击、获取焦点等通知)和定时器等系统事件触发的图形对象状态变更通知。Each interface graphic has attribute, method and event information, which remains relatively stable because it is mainly related to the graphic type. The attribute information of the graphics object includes position, size, color, visibility, etc.; the method information mainly refers to the modification of its attributes, such as moving, zooming in, zooming out, flashing, showing and hiding; the event information is operated by the mouse, keyboard and other interfaces ( Including mouse clicks, mouse double clicks, mouse right clicks, focus acquisition notifications, etc.) and graphical object state change notifications triggered by system events such as timers.
图形对象访问代理可以对图形对象的属性、方法和事件信息进行访问控制，还可以屏蔽图形对象的内部实现细节。每一个图形对象都有且仅有一个访问代理。The graphic object access agent can control the access to the properties, methods and event information of the graphic object, and can also shield the internal implementation details of the graphic object. Each graphics object has one and only one access proxy.
(3)将图形对象访问代理和业务数据适配器模块按照属性、方法和事件关联起来，建立图形对象和业务数据之间的对应关系。(3) Associating the graphic object access agent with the business data adapter module according to attributes, methods and events, and establishing the corresponding relationship between the graphic objects and business data.
根据具体业务应用功能的数据展示和互操作需求，绘制实时监控界面时，首先启动实时界面编辑工具，加载图形对象模板、所需的业务数据适配器模块和图形业务数据关联模块。在编辑工具中新建图形界面数据文件，使用图形模板绘制图形对象，通过图形业务数据关联模块把图形对象代理和业务数据适配器关联起来。According to the data display and interoperability requirements of specific business application functions, when drawing the real-time monitoring interface, first start the real-time interface editing tool, load the graphic object template, the required business data adapter module and the graphic business data association module. Create a graphical interface data file in the editing tool, use the graphical template to draw the graphical object, and associate the graphical object agent with the business data adapter through the graphical business data association module.
图形对象模板中包含了图形对象本体及其访问代理信息，绘图就是主要通过实例化各种图形模板实现的。界面上的图形对象本体信息会被保存到界面数据文件中。The graphic object template contains the graphic object ontology and its access agent information, and the drawing is mainly realized by instantiating various graphic templates. The graphic object ontology information on the interface will be saved to the interface data file.
图形业务数据关联模块的作用是在图形对象和业务数据的属性、方法和事件信息之间建立对应关系，这种对应具体表现为图形对象代理和业务数据适配器之间的关联关系。图形业务数据的关联关系信息，包括其中所涉及到的业务数据适配器模块的名称与配置等信息，会被保存到界面数据文件的相关图形对象中。The function of the graphic business data association module is to establish a corresponding relationship between the graphic object and the attribute, method and event information of the business data. This correspondence is embodied as the relationship between the graphic object proxy and the business data adapter. The association relationship information of the graphic business data, including the name and configuration of the business data adapter module involved therein, will be saved in the related graphic objects of the interface data file.
如图1所示，建立图形对象和业务数据的属性、方法和事件信息之间的特定对应关系，保存到图形对象信息中；修改已有的界面文件时，可以通过图形业务数据关联模块修改或者删除图形对象和业务数据之间的关联关系；在界面文件中删除某一图形对象时，其上的图形业务数据关联信息也会被同步删除。保存界面数据文件时，图形对象信息、业务数据适配器信息及图形对象与业务数据之间的关联信息会被保存到该文件中。As shown in Figure 1, establish the specific corresponding relationship between the attributes, methods and event information of the graphic object and business data, and save it in the graphic object information; when modifying the existing interface file, you can modify it through the graphic business data association module or Delete the association relationship between graphic objects and business data; when a graphic object is deleted in the interface file, the graphic business data association information on it will also be deleted synchronously. When saving the interface data file, the graphic object information, business data adapter information and the association information between the graphic object and business data will be saved in the file.
(4)根据图形对象和业务数据之间的关联关系，使图形对象和业务数据之间互相访问属性、调用方法、传递和接收事件通知，完成实时监控图形界面上的数据展示和互操作功能。(4) According to the relationship between graphic objects and business data, the graphic objects and business data can access attributes, call methods, transmit and receive event notifications, and complete the data display and interoperability functions on the real-time monitoring graphic interface.
使用图形界面系统进行实时监控时，启动实时监控界面程序，打开界面数据文件，创建其中定义的图形对象及其访问代理，在界面上根据图形对象的位置、尺寸、颜色等属性信息对其进行渲染；根据图形业务数据关联信息建立图形对象和业务数据之间的关联关系，加载其中引用的业务数据适配器模块，完成实时监控图形界面上的数据展示和互操作功能。When using the graphical interface system for real-time monitoring, start the real-time monitoring interface program, open the interface data file, create the graphic object and its access proxy defined in it, and render the graphic object on the interface according to its attribute information such as position, size, and color ; Establish the relationship between the graphic object and the business data according to the graphic business data association information, load the business data adapter module referenced therein, and complete the data display and interoperability functions on the real-time monitoring graphic interface.
图形对象和业务数据之间的关联关系是根据应用场景的实际需要而定义的灵活的、多重的、双向的对应关系。一个图形对象可以与一项或多项业务数据建立关联，反之亦然。图形对象的属性刷新和方法调用中可以访问业务数据的属性，图形对象的事件响应中也可以读取或者修改业务数据的属性、调用业务数据的方法来执行业务功能；同样地，业务数据的属性更新和方法调用中可以访问图形对象的属性，业务数据的事件处理中也可以操作图形对象的属性、调用图形对象的方法。The association relationship between graphic objects and business data is a flexible, multiple, two-way correspondence defined according to the actual needs of the application scenario. A graphic object can be associated with one or more business data, and vice versa. The attributes of business data can be accessed in the attribute refresh and method call of the graphic object, and the attribute of the business data can also be read or modified in the event response of the graphic object, and the method of calling the business data can be used to execute the business function; similarly, the attribute of the business data The properties of the graphic object can be accessed during updating and method calling, and the properties of the graphic object can also be manipulated and methods of the graphic object can be called during the event processing of business data.
电力系统的断路器设备有分合状态取值与控分、控合操作，在业务数据适配器模块中将两者分别封装成开关量和控制量业务对象；在实时监控界面上一般用矩形来表示断路器，该矩形对象可以和与此断路器相对应的开关量及控制量分别建立关联关系；该矩形的颜色属性对应开关量的当前状态值属性，红色表明断路器处于闭合状态，绿色表明断路器处于断开状态；根据断路器的当前状态，在矩形上可以通过鼠标双击调用控制量的控合、控分方法对其进行操作，使断路器设备在断开与闭合之间切换状态。The circuit breaker equipment in the power system has the value of the opening and closing state and the operation of controlling opening and closing. In the business data adapter module, the two are respectively packaged into the switching value and the control value business object; on the real-time monitoring interface, it is generally represented by a rectangle Circuit breaker, this rectangular object can establish an association relationship with the switching value and control value corresponding to the circuit breaker; the color attribute of the rectangle corresponds to the current state value attribute of the switching value, red indicates that the circuit breaker is in the closed state, and green indicates that the circuit is open According to the current state of the circuit breaker, double-clicking on the rectangle can call the control method of controlling the closing and opening of the control to operate it, so that the circuit breaker can switch between open and closed.
同一项业务数据可能需要在不同的界面上进行相同或者不同形式的展示，比如某一电压量测量可能需要在主接线图、间隔分图、运行指标图中以文本的形式展示其当前取值；而某一分支开关量，在接线图上需要使用彩色圆形来表示其当前状态值，在信号图上使用矩形光字牌来表示其当前状态值。The same business data may need to be displayed in the same or different forms on different interfaces. For example, a certain voltage measurement may need to display its current value in the form of text in the main wiring diagram, interval sub-diagram, and operation index diagram; As for the switching value of a certain branch, it is necessary to use a colored circle to represent its current state value on the wiring diagram, and to use a rectangular light plate on the signal diagram to represent its current state value.
界面数据文件的初始化过程为：实时监控界面程序首先创建文件中定义的图形对象，每个图形对象再创建各自的访问代理；接着程序遍历处理文件中每个图形对象的图形业务数据关联信息，根据每项关联信息中的业务数据信息，加载对应的业务数据适配器，并根据其中的图形对象和业务数据对应关系，建立图形对象访问代理和业务数据适配器之间的相互引用关联。The initialization process of the interface data file is as follows: the real-time monitoring interface program first creates the graphic objects defined in the file, and each graphic object creates its own access agent; then the program traverses and processes the graphic business data association information of each graphic object in the file, according to The business data information in each associated information loads the corresponding business data adapter, and establishes a mutual reference association between the graphic object access agent and the business data adapter according to the corresponding relationship between the graphic object and the business data.
如图2所示，实时监控图形界面上数据展示功能的一次刷新过程为：界面程序遍历界面上的全部图形对象，根据每个图形对象的图形业务数据关联配置信息，由图形对象访问代理从与此图形相关联的业务数据适配器中获取相应的业务数据属性信息，由业务数据适配器执行具体的数据访问操作获取该业务数据属性，然后再由图形对象访问代理将该业务数据属性信息更新至图形对象的对应属性上，重新渲染图形对象，完成业务数据的一次界面展示。As shown in Figure 2, the refresh process of the data display function on the real-time monitoring graphical interface is as follows: the interface program traverses all the graphical objects on the interface, and according to the configuration information associated with the graphical business data of each graphical object, the graphical object access agent accesses the data from the The corresponding business data attribute information is obtained from the business data adapter associated with this graph, and the business data adapter performs specific data access operations to obtain the business data attribute, and then the graphic object access agent updates the business data attribute information to the graphic object Re-render the graphic object on the corresponding attribute, and complete an interface display of business data.
如图3所示，实时监控图形界面上互操作的一次处理过程为：通过键盘或鼠标操作某一界面图形对象时，引起其发生状态变更，该图形对象产生事件通知，然后事件传递至其访问代理，由图形对象访问代理调用指定的事件处理动作，访问业务数据属性，调用业务数据方法，执行相关业务功能，完成对事件的响应。As shown in Figure 3, the first process of interoperability on the real-time monitoring graphical interface is as follows: when a certain interface graphical object is operated by keyboard or mouse, it causes a state change, the graphical object generates an event notification, and then the event is passed to its access Agent, the graphic object access agent invokes the specified event processing action, accesses business data attributes, invokes business data methods, executes related business functions, and completes the response to events.
业务数据事件的一次处理过程为：业务数据内部状态变更产生了业务事件，该事件通知被传递至业务数据适配器，由适配器调用预先定义的事件响应动作，比如修改图形对象的属性、调用图形对象的方法，完成一次事件驱动的业务数据变更处理。One-time processing of business data events is as follows: a business event is generated when the internal state of business data changes, and the event notification is passed to the business data adapter, and the adapter invokes a predefined event response action, such as modifying the properties of the graphic object, calling the method to complete an event-driven business data change processing.
