    • A transmission control system for a transmission system including a plurality of transmission lines inclusive of closed loops has a plurality of network control processors (NCPs) and devices connected thereto, respectively. Upon issuing of data by a device, an identification code, such as identification number or code allocated inherently to the, is added to the data to be sent to the associated NCP connected to that device, while upon reception of data from the associated NCP, the identification code is checked to avoid duplicate reception of the same data. Also, inter-networking devices may be provided to check the duplicated relaying of the same data between loops. To this end, the transmission control system includes a plurality of transmission lines, a plurality of devices connected to the plurality of transmission lines, respectively, and interconnecting units for interconnecting the plurality of transmission lines through the devices. Each of the devices operates to send out onto the transmission line a message including data generated by the device and to which is added an identification code for identifying the data, and to store the identification code contained in a message upon reception thereof from the transmission line. Upon reception of a message from one of the connected transmission line, the interconnecting unit transmits to the other connected transmission line the message having the identification code which does not coincide with the identification code having been stored before reception of the message from the one connected transmission line.
    • 包括闭环的多个传输线的传输系统的传输控制系统分别具有多个网络控制处理器(NCP)和与其连接的设备。 在通过设备发布数据时,在连接到该设备的相关联的NCP的数据中添加诸如标识号或本身分配的代码的识别码,而在从相关联的NCP接收到数据时, 检查识别码以避免相同数据的重复接收。 此外,可以提供网络间设备来检查循环之间相同数据的重复中继。 为此,传输控制系统分别包括多条传输线,连接到多条传输线的多个设备,以及用于通过设备互连多条传输线路的互连单元。 每个设备操作以向传输线路发送包括由设备生成的数据的消息,并且添加了用于识别数据的识别码,并且在从传输线接收到的信息中存储包含在消息中的识别码 。 在从所连接的传输线中的一个接收到消息时,互连单元向另一个连接的传输线发送具有与从所连接的传输中接收到消息的接收之前已经存储的识别码不一致的识别码的消息 线。

    • The present invention provides, in a system having a plurality of transmission control units which are connected to at least one circular type transmission line, a method of automatically checking the overlap of the addresses of the transmission control units in the circular type transmission system or automatically detecting the structure of the system. In addition, in a double loop transmission system which accompanies bypassing, a bypass route is constructed in correspondence with the occurrence of a fault in the system, and hence, the structure of the system changes. A conventional double loop transmission system does not include means to recognize the structure under which the system is presently operating, and this has been problematic in the maintenance of the system. The present invention is characterized in that the transmission control unit sends an address train message when, for example, it is to be started or it releases the bypass route, that the transmission control units having received the address train message enter their own addresses in succession so as to deliver the resulting messages to a transmission line, and that the source transmission control unit analyzes an address string in the message so as to check the presence or absence of the transmission control unit having the same address as the address of its own. Moreover, the analysis makes it possible to recognize the system structure at that time.
    • 本发明提供一种具有与至少一个圆形传输线连接的多个传输控制单元的系统,该方法可自动检查圆形传输系统中的传输控制单元地址的重叠或自动地检查 检测系统的结构。 此外,在伴随旁路的双环路传输系统中,与系统中的故障的发生相对应地构造旁路路由,因此系统的结构发生变化。 常规的双回路传输系统不包括识别系统当前正在工作的结构的装置,并且这在系统的维护中是有问题的。 本发明的特征在于,发送控制单元在例如要启动或释放旁路路由时发送地址列车消息,接收到地址列车消息的发送控制单元连续地输入自己的地址 以便将所得到的消息传递到传输线,并且源传输控制单元分析消息中的地址串,以便检查具有与其自身的地址相同的地址的传输控制单元的存在或不存在。 此外,分析使得可以识别当时的系统结构。
