    • A distributed computer-implemented building automation system for supporting applications that interact with building automation devices. The building automation system has a first device and a second device interconnected across a network channel. A common object superclass stored in a computer readable memory defines a plurality of common objects through instantiation such that the common objects have attributes for storing data and have methods for processing stored data. A source object residing on the first device performs a first control method such that a first attribute of the source object is changed. A destination object residing on the second device performs a second control method using the first attribute of the source object. A surrogate object connected between the source object and the destination object has a value for the first attribute and represents the source object on the second device. The second object has access to the value of the first attribute for performing the second method.

    • A computer-implemented building automation system provides a computer software architecture that supports object-oriented system development. An application engineer designs an application to perform a building automation function that solves a problem or customer need in the context of a building automation system. In the object-oriented paradigm, standard objects are the fundamental building block used to construct an application. Based on predetermined physical relationships defined by physical laws associated with building automation functions, the present invention defines a fundamental set of control-based standard objects for constructing an application. An additional set of information-type standard objects have also been defined for use in conjunction with this set of control-based standard objects. Standard objects are interconnected by "pulling" or "pushing" information from one standard object to another standard object using common communication methods. Assembly objects and application objects are two additional types of user-defined standard objects for interconnecting standard objects, thereby constructing a building automation application.
    • 计算机实现的楼宇自动化系统提供支持面向对象系统开发的计算机软件架构。 应用工程师设计一个应用程序来执行楼宇自动化功能,以在建筑物自动化系统的上下文中解决问题或客户需求。 在面向对象的范例中,标准对象是用于构建应用程序的基本构建块。 基于与建筑物自动化功能相关联的物理规律定义的预定物理关系,本发明定义了一组用于构建应用的基于控制的标准对象。 还定义了一组附加信息类型的标准对象,以与该组基于控件的标准对象结合使用。 标准对象通过使用通用通信方式将信息从一个标准对象“拉”或“推”到另一个标准对象来互连。 组装对象和应用程序对象是用于互连标准对象的两种附加类型的用户定义的标准对象,从而构建楼宇自动化应用程序。

    • A computer-implemented building automation system is provided with an asynchronous communication architecture for supporting object-oriented applications that interact with distributed building automation devices. Standard application objects which need to be informed of changes to the value of another object's attributes use a connection object to establish an asynchronous link between standard objects. A source object has a control attribute that changes based upon the execution of this object's control method which in turn is linked to a second control attribute of a destination object. By linking these attributes, a connection object is defined to manage information being passed between these two objects. Upon instantiation of the connection object, it registers the second control attribute with the source object to receive "significant" changes in the value of its control attribute. A "significant" change is defined by a change sensitivity property associated with the control attribute, such that a message containing the value of the control attribute is transmitted to the connection object when the change in the value of the control attribute exceeds the value of the change sensitivity property. The connection object in turn writes the attribute's value from the source object to the second control attribute of the destination object. Thus, execution of the connection object happens independently from the destination object. This communication architecture also implements a reliability data structure to improve asychronous communication when the building automation system is distributed across various building automation devices.
    • 计算机实现的楼宇自动化系统被提供有异步通信架构,用于支持与分布式楼宇自动化设备交互的面向对象的应用。 需要通知对另一个对象属性的值的更改的标准应用对象使用连接对象来建立标准对象之间的异步链接。 源对象具有基于该对象的控制方法的执行而改变的控制属性,该控制方法又连接到目的地对象的第二控制属性。 通过链接这些属性,定义连接对象来管理在这两个对象之间传递的信息。 在实例化连接对象后,它将第二个控制属性与源对象注册,以便在其控件属性的值中接收“重要”更改。 通过与控制属性相关联的变化敏感度属性来定义“显着”变化,使得当控制属性的值的改变超过了控制属性的值时,包含控制属性的值的消息被发送到连接对象 改变敏感性。 连接对象又将属性的值从源对象写入目标对象的第二个控件属性。 因此,连接对象的执行独立于目标对象发生。 当建筑物自动化系统分布在各种楼宇自动化设备中时,该通信架构还实现可靠性数据结构以改善异步通信。

    • A computer-implemented building automation system is provided with an asynchronous object-oriented operating environment that is able to provide support for synchronous object execution with respect to real time, including those used to maintain closed-loop control over a system. The operating environment for supporting standard objects includes a clock mechanism for maintaining time and a scheduling mechanism for initiating the methods associated with the standard objects. A control method (i.e. PID control method) of a first standard object is scheduled for execution at a predefined schedule time with the schedule mechanism, and at some later time is initiated by the schedule mechanism. Upon execution, the control method determines an actual time of initiation by reading the clock mechanism and adjusts its control method using this actual time when the actual time exceeds the schedule time. More specifically, the actual time is determined by reading an elapsed time from the clock mechanism and computing a difference between this elapsed time and a start time that was determined by reading the clock mechanism at the time the control method was scheduled.
    • 计算机实现的楼宇自动化系统被提供有异步面向对象的操作环境,其能够相对于实时地提供对同步对象执行的支持,包括用于维护对系统的闭环控制的那些。 用于支持标准对象的操作环境包括用于维护时间的时钟机制和用于启动与标准对象相关联的方法的调度机制。 第一标准对象的控制方法(即,PID控制方法)被调度为使用调度机制在预定的调度时间执行,并且在稍后的时间由调度机制启动。 在执行时,控制方法通过读取时钟机构来确定启动的实际时间,并且当实际时间超过调度时间时,使用该实际时间来调整其控制方法。 更具体地说,通过从时钟机构读取经过的时间并计算在调度控制方法时通过读取时钟机构确定的经过时间和开始时间之间的差来确定实际时间。
