    摘要: A very useful data transmission system having a plurality of transmission modules connected to a single cable in a multidrop manner is disclosed herein. The system features its ability to check the transmission state at the level of individual modules through use of a proper code notation (typically, Manchester code). The system detects a specific module with proper signals lasting at the same level for more than a given time, except cable outputs, and treats it as involving a faulty condition and compels the transmission state to a halt, thus preventing only the faulty module or modules from transmitting signals thereby avoiding breakdown of the whole system.

    摘要: A data transmission method over building wiring includes a plurality of transmission sections. One of these sections is selected from the plurality of transmission sections to be a data transmission source machine for providing data. The data is transmitted from the data transmission source to the remaining transmission sections. If a transmission section is not selected it is used to relay the data to one of the remaining transmission sections wherein it is received by a final data transmission section. A data transmission section used in the method, comprises a data receiving part for receiving the transmitted data, a relay counter part for counting the number of relaying the transmitted data, and data relaying part for steps of relaying the-received data.
