Title:
POWER LINE COMMUNICATION SYSTEM, DEVICE STATE QUERY METHOD, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/246660
Kind Code:
A1
Abstract:
Provided in the present application are a power line communication system, a device state query method, and a device. The power line communication system comprises a central coordinator and a plurality of stations, wherein a target station is one of the plurality of stations at any stage; the central coordinator sends a scenario control instruction to the plurality of stations in a broadcast mode; the central coordinator sends a first query message to a plurality of first-stage stations in a broadcast mode, the first query message being used for indicating a reporting sequence of the plurality of first-stage stations reporting a device state to the central coordinator; and the target station determines, according to the first query message, a target reporting sequence of the target station reporting the device state, and sends device state information of the target station to the central coordinator when it is determined that a target reporting sequence is reached. By means of the power line communication system, a plurality of stations can report device state information in a sequence indicated by a central coordinator, without causing channel conflicts, and the central coordinator also does not need to respectively send a query message to each station in a unicast mode, thereby reducing the number of sent packets, and improving the communication efficiency.
