Embodiment 1

[0026] Such as figure 1 As shown, the present invention provides a preferred data acquisition system 100 , which includes: a terminal 104 and a remote device 102 .

[0027] Wherein, the remote device 102 includes: a splitting unit 1022, configured to split the data packet to be transmitted into multiple data blocks, and assign a unique identifier to each data block; a first sending unit 1024, configured to send The terminal sends multiple data blocks and an identifier corresponding to each data block.

[0028] The terminal 104 includes: a receiving unit 1042, configured to receive multiple data blocks sent by the remote device and an identifier corresponding to each data block, wherein the remote device splits the data packet to be transmitted into multiple data blocks, and A unique identifier is assigned to each data block; the processing unit 1044 is used to store the received multiple data blocks and the identifier corresponding to each data block on the local storage devi...

Embodiment 2

[0035] based on Figure 1-4 The preferred data acquisition system shown, the present invention also provides a preferred data acquisition method, such as Figure 5 As shown, the specific steps of the method include:

[0036] S502: The terminal receives multiple data blocks sent by the remote device and the identifier corresponding to each data block, wherein the remote device splits the data packet to be transmitted into multiple data blocks and assigns a data block to each data block. unique identification;

[0037] S504: The terminal stores the received multiple data blocks and the identifier corresponding to each data block in the local storage device;

[0038] S506: The terminal judges whether there is a data block that needs to be resent by the remote device among the multiple data blocks;

[0039] S508: If it exists, the terminal acquires the data block that needs to be resent by the remote device from the local storage device according to the identifier corresponding...

Abstract

The invention discloses a data acquisition method, a terminal and a far-end device. The data acquisition method comprises that the terminal receives a plurality of data blocks transmitted by the far-end device and identifications corresponding to the data blocks, wherein the far-end device divides a data packet to be transmitted into the plurality of data blocks and distributes one unique identification for each data block; the terminal stores the plurality of received data blocks and the received identifications corresponding to the data blocks in a local storage device; the terminal judges whether data blocks required to be re-transmitted by the far-end device exist in the plurality of data blocks or not; and the terminal acquires the data blocks required to be re-transmitted by the far-end device from the local storage device according to the identifications corresponding to the data blocks required to be re-transmitted by the far-end device on yes judgment. By adopting the data acquisition method, the terminal and the far-end device, the problem that normal system operation is difficultly ensured when data traffic of a data center increases rapidly due to limited device processing capability is solved, and the effects of reducing the network traffic and improving network response speed are achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data acquisition method, a terminal and a remote device. Background technique [0002] The current electric power information network is generally deployed in a distributed manner. The grassroots and the headquarters are connected through optical fibers. A data center is built at the headquarters, which serves as the core of the network. There will be certain problems in the data center deployed in a centralized manner. The main reason is that the processing capacity of the equipment is limited, which is too different from the wire-speed forwarding speed of the switch. Therefore, it is difficult for the data center to ensure the stability of the system when the data traffic increases sharply. The operation of the traditional method of increasing the access speed by continuously increasing the bandwidth has very little effect. How to reduce the network traffic and effectively...
