Ethernet-based intelligent terminal interaction system

Abstract

The invention relates to an Ethernet-based intelligent terminal interactive system, which comprises a master station and at least two terminals, wherein the master station sends a command to the terminals and receives data uploaded by the terminals; the at least two terminals are connected to the master station to realize information transmission; the terminal and the adjacent terminal are connected in an Ethernet mode to form an Ethernet local area network, so that information sharing between the terminals is realized; and one or more terminals serve as relay stations and are connected to themaster station and are used for forwarding the command or transmitting the data. Compared with the prior art, through the intelligent terminal interaction system provided by the invention, the stability of data transmission can be effectively improved, the pressure of the master station is reduced, and the stability of the system is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to an intelligent terminal interaction system based on Ethernet. Background technique [0002] The existing communication system still uses the "one-to-many" transmission method of one master station corresponding to multiple terminals for information transmission, and the interconnection and intercommunication between terminals cannot be realized, and information sharing cannot be realized. Such as figure 1 As shown, each terminal only realizes information uplink and downlink with the main station, and there are many shortcomings in this communication method. [0003] For example, for the power terminal system, some electric energy meter devices have poor GPRS signal due to their poor environment. The task assigned by the station, or when some electric energy meters report data to the master station, due to poor communication quality, the reported data items lose data, and the master st...

Problems solved by technology

[0003] For example, for the power terminal system, some electric energy meter devices have poor GPRS signal due to their poor environment. The task assigned by the station, or when some electric energy meters report data to the master station, due to poor communication quality, the reported data items lose data, and the master station cannot receive complete data, resulting in low collection rate and missing power data

[0004] Although researchers have tried to realize information interaction between terminals through 485 lines, this method has disadvantages such as low bus utilization rate, low data transmission rate and slow speed of single-master network, no fault tolerance mechanism and high communication failure rate, which cannot meet the actual requirements.
