A method, device and system for transmitting data

Abstract

Embodiments of the present invention provide a method, device, and system for transmitting data, which relate to the field of communication technology and can guarantee better real-time performance of transmitted data to a certain extent. The PLC system includes a management server, a master device, a master PLC device, a slave PLC device and a slave device. The master device and the management server are wirelessly connected, the master PLC device provides a PLC interface for the master device, and the slave PLC device provides a PLC interface for the slave device. The master device and the slave device are in the same local area network. The slave device in the PLC system sends the first uplink data to the slave PLC device; the slave PLC device forwards the first uplink data to the master PLC device; the master PLC device adds the identification information of the slave PLC device to the first uplink data, so that the first One uplink data is encapsulated into second uplink data, and the second uplink data is sent to the master device; the master device decapsulates the second uplink data, obtains the first uplink data, and then sends the first uplink data to the management server.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device, and system for transmitting data. Background technique [0002] With the continuous development of Internet communication technology, the Internet of Things communication technology has emerged as the times require, and the application of the Internet of Things is becoming more and more extensive. Multiple objects in the Internet of Things (such as multiple charging piles) can establish communication connections through networking technology, so that data can be transmitted between these objects. [0003] For example, taking the charging system in the power line communication (Power Line Communication, PLC) system as an example, usually, after the networking between multiple charging piles in the charging system is successful, the multiple charging piles can send data to the server of the operation platform. Specifically, the...

[0004] However, in the above method, since the data acquisition device in the charging system queries the status of multiple charging piles in a polling manner, when a certain charging pile among the multiple charging piles needs to send uplink data to the server of the operation platform , the charging pile may have to wait for a period of time, that is, the charging pile can only send data to the server when the data collection device inquires about the charging pile, which may result in poor real-time transmission of data
