Embodiment 1

[0094] The embodiment of the present invention provides a communication method, such as figure 1 shown, including:

[0095] 101. A multi-phase device determines a first phase corresponding to a current phase time slot; wherein, a phase time slot corresponding to a phase refers to a time period for enabling the multi-phase device to communicate with a single-phase device on the phase.

[0096] The communication method provided by the embodiment of the present invention can be applied to the power line communication technology. "Multi-phase equipment" refers to equipment powered by multiple phases, for example, it can be: two-phase equipment or three-phase equipment. "Single-phase equipment" means equipment powered from a single phase. Specifically, the multi-phase device may be a CCO (Central Coordinator, central coordinator), and the single-phase device may be an STA (station, station).

Embodiment 2

[0113] The embodiment of the present invention also provides a communication method, such as image 3 shown, including:

[0114] 301. The single-phase device receives a notification message sent by the multi-phase device, wherein the notification message carries information about a phase time slot corresponding to the phase where the single-phase device is located, and the phase time slot refers to a phase time slot used for A period of time for the single-phase device to communicate with the multi-phase device.

[0115] It should be noted that, for explanations of related content in this embodiment, reference may be made to the foregoing.

[0116] Optionally, before step 301, the method may also include the following steps 1)-3):

[0117] Step 1), the single-phase device receives the phase evaluation frame sent by the multi-phase device on each phase, wherein the phase evaluation frame carries the phase information used when sending the phase evaluation frame, and is used t...

Embodiment 3

[0135] This embodiment is described by taking the multi-phase device as a three-phase device as an example. The phases of the three-phase equipment are expressed as: A phase, B phase and C phase, and the phase lines corresponding to the A phase, B phase and C phase are respectively expressed as: A phase line, B phase line, and C phase line.

[0136] see Figure 9 , a communication method provided by this embodiment, including:

[0137] 901: The three-phase device periodically sends a phase evaluation frame on three phases to a primary single-phase device connected to the three-phase device.

[0138] Specifically: within a period T, the three-phase device sends a phase evaluation frame through the A-phase line, the B-phase line, and the C-phase line respectively in sequence. Wherein, this embodiment does not limit the sequence, for example, it may be: A-phase line, B-phase line, C-phase line, or it may be B-phase line, C-phase line, A-phase line, etc.

[0139] In this embodi...

Abstract

An embodiment of the present invention discloses a communication method, apparatus and system, relates to the field of communication, and is used to solve the problem of complex realization process due to the requirements of data synchronism between communication chips, and the problem of weak communication signal and weak communication ability of a single phase device due to the communication achieved by coupling. The communication method provided in the embodiment of the present invention includes: multiphase device determines a first phase corresponding to a current phase time slot, wherein, the phase time slot corresponding to a phase refers to a time period used for communication between the multiphase device and the single phase device at the phase; and when in the current phase time slot, communicating with the single phase device at the first phase. The technical solution provided by the embodiment of the present invention can be used in the field of power line communication.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a communication method, device and system. Background technique [0002] Most of the substations use three-phase electricity to supply power to residents, but in fact residents use single-phase electricity; the equipment powered by three-phase electricity is called three-phase equipment, and the equipment powered by single-phase electricity is called single-phase electricity. phase device. At present, the communication between three-phase equipment and single-phase equipment is generally realized through the following two schemes: [0003] Solution 1: Set up a communication chip on the phase line corresponding to each phase of the three-phase equipment. A three-phase device communicates with a single-phase device on that phase using a communication chip on each phase line. [0004] Solution 2: Set up a communication chip on phase lines corresponding to two phase...
