Abstract

Provided in the embodiments of the present invention are a data transmission method and system therefor, an electrical gateway and a master station. The method comprises: an electrical gateway receiving first data frames sent from a plurality of terminal devices respectively, the data portion of each such data frame including the reporting data of a terminal device; the electrical gateway analysing each first data frame and acquiring and storing the reporting data from each such frame; on the basis of the stored reporting data, the electrical gateway generating a second data frame, the data portion whereof includes a plurality of reporting data sets, then sending the second data frame to the master station. Under the technical solution of the present invention, an electrical gateway, by means of storing reporting data from terminal devices and transmitting in a single connection to a master station the reporting data from a plurality of terminal devices, reduces the number of communications between itself and the master station, thus also reducing wireless network traffic and limiting waste of network resources.

Description

technical field [0001] The invention relates to power communication technology, in particular to a data transmission method, system, power gateway and master station. Background technique [0002] Distribution Line Message Specification (DLMS) is an international standard protocol for communication in the power industry. At present, the terminal equipment monitoring system based on DLMS mainly includes a main station, a power gateway and multiple terminal equipments. Among them, the master station and the power gateway generally carry out data transmission through wireless networks, such as the third-generation mobile communication (3rd-Generation, 3G) network and the general packet radio service (General Packet Radio Service, GPRS) network; the power gateway and the terminal The device generally performs data transmission through a local home area network (Home area network, HAN), such as a power line carrier communication (Power Line Carrier Communication, PLC) or a radio...
