According to an aspect, there is provided an elevator communication system comprising a communication bus (112) applying a master-slave protocol, a master node (100) connected to the communication bus (112), and at least one slave node (102-110) connected to the communication bus (112). The master node (100) and the at least one slave node (102-110) are configured to apply a repeating frame structure for data communication in the communication bus (112) in which a first slot of a frame is reserved for the master node (100) and each slave node (102-110) of the at least one slave node (102-110) has a dedicated slot in remaining slots of the frame. The master node (100) is configured to extend the time between consecutive frames in order to enable a power saving mode of the communication bus (112).
根据一方面,提供了一种电梯通信系统,包括应用主从协议的通信总线(112)、连接到通信总线(112)的主节点(100)和连接到通信总线(112)的至少一个从节点(102‑110)。主节点(100)和至少一个从节点(102‑110)配置为针对所述通信总线(112)中的数据通信应用重复帧结构,在所述重复帧结构中,为所述主节点(100)预留帧的第一时隙,并且在所述帧的剩余时隙中,所述至少一个从节点(102‑110)中的每个从节点(102‑110)具有专用时隙。所述主节点(100)配置为延长连续帧之间的时间,以便启用所述通信总线(112)的功率节省模式。
