    • The present invention relates to a node in distributed communication system operating under a time triggered protocol, further it relates to distributed communication system and to a monitoring device coupled to such node of a communication system. To provide a node in a distributed communication system, a distributed communication system and a monitoring device increasing the error detection and reducing complexity for providing a high availability for systems which require a non 100% fail safe solution a node is proposed comprising: a communication controller (15) coupled to a receiving and a transmission path, a host (13) for performing an application, and a monitoring device (16) coupled at least to one of a transmission path of the communication controller (15), an interface (91) between communication controller (15) and the host (13), and to internal lines of the communication controller (15), wherein the monitoring device (16) is provided for evaluating information provided by the communication controller (15) to monitor at least one state of the communication controller (15), wherein in case of detecting a non-defined state the host (13) is informed for performing predetermined actions in respect to the state of the communication controller (15). Thereby, an easy cost reduced solution is provided adapted to detect a predetermined number of faults in a distributed communication system.
    • 本发明涉及在时间触发协议下运行的分布式通信系统中的节点,此外还涉及分布式通信系统和耦合到通信系统的这种节点的监控设备。 为了在分布式通信系统中提供节点,分布式通信系统和监视设备增加了错误检测并降低了复杂度,以便为需要非100%故障安全解决方案的系统提供高可用性,该节点被提出包括:通信控制器 (15),耦合到接收和传输路径,用于执行应用的主机(13)和至少耦合到所述通信控制器(15)的传输路径之一的监视设备(16),接口(91) )和通信控制器(15)的内部线路之间,其中所述监视设备(16)被提供用于评估由所述通信控制器(15)提供的信息以至少监视至少 通信控制器(15)的一个状态,其中在检测到未定义状态的情况下,主机(13)被通知以针对所述通信的状态执行预定动作 使用控制器(15)。 因此,提供了适于检测分布式通信系统中的预定数量的故障的简单的成本降低的解决方案。

    • The present invention relates to a clock supervision unit (100) and an electronic system clocked by at least one clock (c*) and using the clock supervision unit (100). The clock supervision unit (100) analyzes the at least one clock (c*) based on a monitor clock (m*) provided together with the at least one clock (c*) or separately to the clock supervision unit (100). The clock supervision unit (100) at least comprises an activity unit (210), a deviation unit (220) and an auxiliary clock generator (240). The auxiliary clock generator (240) outputs an auxiliary clock (a*). The activity unit (210) detects the presence of the monitor clock (m*) based on the auxiliary clock (a*) and the presence of the auxiliary clock (a*) based on the monitor clock (m*). The deviation unit (220) detects clock faults in the monitor clock (m*) based on the auxiliary clock (a*). With the clock supervision unit (100) according to the present invention, the at least one clock (c*) can be supervised in more detail and it is possible to react on different clock faults in the at least one clock c* with different error handling procedures, e.g. by initiating a shutdown of the devices controlled by the electronic system.
    • 本发明涉及时钟监控单元(100)和由至少一个时钟(c *)定时并使用时钟监控单元(100)的电子系统。 时钟监视单元(100)基于与至少一个时钟(c *)一起提供的监视时钟(m *)或单独地与时钟监视单元(100)分析至少一个时钟(c *)。 时钟监控单元(100)至少包括活动单元(210),偏差单元(220)和辅助时钟发生器(240)。 辅助时钟发生器(240)输出辅助时钟(a *)。 活动单元(210)基于辅助时钟(a *)和基于监视时钟(m *)的辅助时钟(a *)的存在来检测监视时钟(m *)的存在。 偏差单元(220)基于辅助时钟(a *)检测监视时钟(m *)中的时钟故障。 利用根据本发明的时钟监视单元(100),可以更详细地监视至少一个时钟(c *),并且可以对具有不同错误的至少一个时钟c *中的不同时钟故障作出反应 处理程序,例如 通过启动由电子系统控制的设备的关闭。
