At least two terminals are connected with the main website, realize information transmission；
It is characterized in that：
It is connected between the terminal and adjacent end by ether net mode, forms ethernet local area network, realize terminal and terminal
Between information sharing；
It is one or several as relay station in the terminal, it is connected with the main website, to forward the order or biography
Send the data.
Further, it is handed between the terminal and adjacent end with transparent transmission or broadcast mode by ethernet local area network into row information
Mutually.
Further, the mode of the main website at least two terminal transmission order is：
The relay station receives the message commands that the main website is sent；
The relay station forwards the message commands by ethernet local area network with transparent transmission or broadcast mode to adjacent end；
The adjacent end continues to pass through described in ethernet local area network to other adjacent ends forwarding with transparent transmission or broadcast mode
Message commands, until all terminals receive the message commands.
Further, the mode of the terminal to main website upload data is：
Data are transferred to the relay station by the terminal that need to upload data in a manner of transparent transmission by ethernet local area network；
The relay station judges the data data are intended for main website if judging, by data original
Sample is transmitted to the main website.
Further, whether the relay station judges the data by identifying the destination-mac address in the data
It is sent to main website.
Further, also include to identify the information source MAC Address of the data source in the data, the main website according to
The terminal of data need to be uploaded by knowing according to the information source MAC Address.
Further, it is transmitted between the relay station and the main website by GPRS wireless public networks into row information.
Further, the relay station is received by signal and the good terminal of transmission quality is formed.
Further, the ethernet local area network connects the terminal and adjacent end using cable as transmission media.
Further, the terminal realizes the correction of upgrading, error message with terminal room by ethernet local area network；The end
End is equipped with the network interface for communication module configuration.
Compared with prior art, the utility model has the advantage of：Industry ethernet utilization rate is high, communication data transfer is fast
And be not in loss of data, communication failure rate is low, there is reliable error handle and error-detection mechanism, is realized using the networking mode
The information exchange of terminal and terminal room makes all terminals realize data sharing under a channel, can effectively avoid " a pair of
It is more " information of formula main website-existing for multiple terminals loses, and information transmits incomplete problem, improves the stability of system.
Description of the drawings
Fig. 1 is the connection diagram of one main website-multiple terminals of the prior art.
Fig. 2 is the connection diagram of intelligent terminal interactive system of the utility model based on Ethernet.
Specific embodiment
The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and it is not intended that the utility model
Limitation.
The embodiment of a kind of intelligent terminal interactive system based on Ethernet shown in Fig. 2 for being the utility model, at this
In embodiment, system tool is there are one main website, multiple terminals, compared to " one-to-many " connection of main website-terminal of the prior art
Mode (as shown in Figure 1), one or several signal transmission qualities in main website and multiple terminals in the present embodiment are good to be passed through
GPRS wireless public networks connect, and the good terminal of one or several signal transmission qualities as relay station, is come independently for forwarding
The order and upload stood carry out the data of self terminal.To realize the purpose, lead between each terminal and adjacent end in the present embodiment
Cross the connection of Ethernet networking mode, transmission media using cable, naturally it is also possible to using other transmission mediums.
Ethernet uses CSMA/CD agreements as defined in IEEE802.3 standards, has the characteristics that shared channel, can allow more
A terminal shares a channel and carries out data transmission, and realizes resource-sharing.Existing 485 line networking mode bus utilization is low,
Data transmission rate low velocity is slow, high without fault tolerant mechanism, communication failure rate, can not meet actually making for different terminals information interaction
With demand, and industry ethernet utilization rate is high, and communication data transfer speed is fast and is not in loss of data, communication failure rate
It is low, there is reliable error handle and error-detection mechanism, terminal friendship can be greatly promoted to communicate using based on the new paragon of Ethernet
Interaction performance.
Specifically, be connected between main website and the relay station chosen using GPRS wireless public networks in the present embodiment, terminal and terminal
Between cascaded by cable with ether net mode, form terminal ethernet local area network, all terminals realize number under a channel
According to shared.
If sending message commands downwards, the relay station such as terminal 1 selected receives main website by wireless public network GPRS and sends
Binary system message commands, and continue by ethernet local area network in a manner of transparent transmission or broadcast to forward the message commands, ether
Net continues to transmit the binary string to next terminal, until all terminals in LAN receive the complete phase issued with main website
Same message commands, each terminal complete the task of main website explanation according to the message commands, such as acquire correlation electric flux, data are used
Electricity, various terminals associated event data etc..
If desired data are uploaded, then ask the terminal for uploading data first will the binary system such as energy data by cable
String passes through the good terminal 1 of signal, and terminal 1 is after this transparent data frame is received, by identifying the target in the data frame
MAC Address is also intended for main website in itself to judge that the data frame is destined to terminal, if requirement is sent to main website, then the data
Frame can send main website to, while also include information source MAC Address in the data frame by intact by GPRS wireless public networks,
Main website can judge which terminal is the data be from by identifying the information source MAC Address.
It either sends message and still uploads data, all information all first pass through one or several ends as relay station
End, is then forwarded or is uploaded by the relay station again, such transmission mode avoids the connection of " one-to-many " formula main website-multiple terminals
In, probably due to certain terminal installation sites are bad, GPRS signals are bad, can not receive message commands or can not completely upload number
According to the problem of, while the pressure of main website is alleviated, so as to which the stability of entire communication system is effectively ensured.
Meanwhile the connection mode can be realized when certain terminal time of occurrence entanglements, when can will have correct with Ethernet
Between the corresponding temporal information of terminal be sent to mistake terminal, calibrated；And which can realize that remote terminal upgrades,
The terminal connected is upgraded by Ethernet transmission, speed is fast, and reliability is high.
Other than above-mentioned improvement, other similar improvement are also contained in the improvement threshold of the utility model, herein
It is not repeating.While there has been shown and described that the embodiment of the utility model, it will be appreciated by those skilled in the art that：It is not taking off
In the case of principle and objective from the utility model can these embodiments be carried out with a variety of variations, modification, replace and deform.
