    • The invention relates to a method of transmitting user data via a communications medium (2) between subscribers (3) connected to the communications medium (2), wherein the data are transmitted in recurrent cycles (8) and at least one slot (9, 10) in each cycle (8) is intended for the user data of at least one subscriber (3). In order to permit a particularly efficient data transmission via the communications medium (2) at least one of the slots (10) is used to transmit the user data of different subscribers (3) (A, C, F) in different cycles (8). In addition, a bus guardian (6) of one subscriber (3) determines whether the subscriber (3) may transmit user data in the current slot (9, 10) of the current cycle (8), the bus guardian (6) having at least indirect access to a universal condition available throughout the entire communications system (1). In particular, an internal counter of the bus guardian (6) is synchronized to a universal cycle counter.
    • 本发明涉及一种通过连接到通信介质(2)的用户(3)之间的通信介质(2)发送用户数据的方法,其中数据以循环周期(8)和至少一个时隙(9, 每个周期(8)中的10)用于至少一个订户(3)的用户数据。 为了允许经由通信介质(2)的特别有效的数据传输,使用时隙(10)中的至少一个用于以不同的周期(8)发送不同用户(3)(A,C,F)的用户数据 )。 另外,一个用户(3)的总线监控器(6)确定用户(3)是否可以在当前周期(8)的当前时隙(9,10)中发送用户数据,总线监控器(6)具有 至少间接访问整个通信系统(1)中可用的通用条件。 特别地,总线监控器(6)的内部计数器与通用周期计数器同步。

    • In order to carry out in a communication system (1) a temporal synchronization of clocks in a particularly rapid and efficient manner, a method is proposed which has the following steps: acquiring state values which are dependent on a time base (10); filing each acquired state value at a position in a first list L comprising (k+l) positions, if the acquired state value is smaller than or equal to the (k +1) smallest element of the list L, where k is a predefinable error tolerance; filing the acquired state value at a position in a second list H comprising (k+l) positions, if the acquired state value is greater than or equal to the (k+1) greatest element of the list H; forming a mean value from the (k+1) smallest element of the list L and the (k+l) greatest element of the list H, if the number of acquired state values is greater than or equal to (2k+2); determining a correction value as a function of the mean value; and correcting a current state value of the clocks that are to be synchronized.
    • 为了以特别快速和有效的方式在通信系统(1)中执行时钟的时间同步,提出了一种方法,其具有以下步骤:获取取决于时基(10)的状态值; 如果所获取的状态值小于或等于列表L的(k + 1)最小元素,则在包括(k + 1)个位置的第一列表L中的位置处归档每个获取的状态值,其中k是可预定义的 误差容差 如果获取的状态值大于或等于列表H的(k + 1)个最大元素,则在包括(k + 1)个位置的第二列表H中的位置处归档所获取的状态值; 如果所获取的状态值的数目大于或等于(2k + 2),则从列表L的(k + 1)最小元素和列表H的(k + 1)最大元素形成平均值; 确定作为所述平均值的函数的校正值; 并且校正要同步的时钟的当前状态值。

    • The present invention relates to a method of controlling a lighting system, the lighting system being arranged as a wireless network comprising a controller and a plurality of operating nodes arranged to communicate with each other, wherein the method comprises the steps of synchronizing the operating nodes with the controller, determining, from the plurality of operating nodes, a set of operating nodes that are located within a predetermined operating area, estimating a state-shift delay based on a maximum communication delay between the controller and the set of operating nodes located within the predetermined operating area, communicating the estimated state-shift delay to the plurality of operating nodes, and communicating a state-shift command to the plurality of operating nodes. An advantage with the invention is that the visual artifact of the state- shift may be essentially removed as the time synchronization and timer interrupt alignment together with the estimated state-shift delay allows for the plurality of nodes to shift state at essentially the same time.
    • 本发明涉及一种控制照明系统的方法,所述照明系统被布置为包括控制器和布置为彼此通信的多个操作节点的无线网络,其中所述方法包括以下步骤:将所述操作节点与 所述控制器从所述多个操作节点确定位于预定操作区域内的一组操作节点,基于所述控制器与位于所述操作区域内的所述一组操作节点之间的最大通信延迟来估计状态移位延迟 将所述估计状态移动延迟传送到所述多个操作节点,以及将状态转移命令传送到所述多个操作节点。 本发明的优点在于,由于时间同步和定时器中断对准以及估计的状态移位延迟允许多个节点在基本上相同的时间移位状态,所以可以基本上去除状态移位的视觉伪影。
