    • A communication method in an automation system, wherein the system comprises an access point and client terminals that receive downlink data sent from the access point and send uplink data to the access point, and the data transmission is divided into a master multiple receiver aggregation phase and more than one slave multiple receiver aggregation phases. During the master multiple receiver aggregation phase, the access point aggregates the data to be sent to the plurality of client terminals into one packet for transmitting in the downlink, and during the slave multiple receiver aggregation phases, the access point aggregates data in which errors have occurred when being transmitted during the master multiple receiver aggregation phase into one packet for transmitting in the downlink. The method can have strict control, through the access point and over the uplink and downlink data transmission, thus enhancing the certainty during automation communication and further reducing the cycle time.
    • 一种自动化系统中的通信方法,其特征在于,所述系统包括接入点和接收从所述接入点发送的下行链路数据并向所述接入点发送上行链路数据的客户终端,所述数据传输分为主多接收机聚合阶段和 多个从站多个接收机聚合阶段。 在主多接收机聚合阶段期间,接入点将要发送给多个客户终端的数据聚合成一个分组,用于在下行链路中进行传输,而在从属多个接收机聚合阶段期间,接入点聚合错误具有的数据 当在主多个接收机聚合阶段期间被发送到一个用于在下行链路中发送的分组时发生。 该方法可以通过接入点和上行链路和下行链路数据传输进行严格的控制,从而提高自动化通信中的确定性,进一步缩短周期时间。

    • An RFID reader/writer including a reader/writer body, antennas and an antenna switching unit is provided. The reader/writer body distributes to each of its own ports a length of sustained time for transmitting a signal. One end of the antenna switching unit is connected to one port of the reader/writer body, while the other end is connected to two antennas. The antenna switching unit acquires a length of sustained time for the signal transmission distributed to the port by the reader/writer body, configures the time-length for the signal transmission and the sequence thereof of the two antennas according to the length of sustained time for the signal transmission, obtains a configuration result for signal transmission, and performs a switching control on the signal transmission of the two antennas according to the signal transmission configuration result. Further, an implementation method for the antenna switching of the RFID reader/writer is described.
    • 提供了包括读写器本体,天线和天线切换单元的RFID读写器。 读/写器主体向每个自身端口分配用于发送信号的持续时间长度。 天线切换单元的一端连接到读写器主体的一个端口,而另一端连接到两个天线。 天线切换单元获取由读写器主体分配给端口的信号传输的持续时间长度,根据持续时间的长度来配置信号传输的时间长度及其两个天线的序列 信号传输,获得用于信号传输的配置结果,并且根据信号传输配置结果对两个天线的信号传输执行切换控制。 此外,描述了用于RFID读取器/写入器的天线切换的实现方法。
