Description
Technical field
The present invention relates to network data communication agreement and data transaction field, relate in particular to a kind of agreement and DTU (Data Transfer unit) and method.
Background technology
In relating to the system of transfer of data, often have and need to belong to the process that the data of heterogeneous networks forward each other, transmit.While data content wherein also need to convert and process in the process of protocol conversion.
In the application of sensor network and Internet of Things, communication system is one of them important component part.At present in most of sensor networks or Internet of Things communication system, great majority transmission is to adopt communication, communication network wherein generally comprises two or several parts: a part is to adopt low rate, in-plant communication, as the mode of ZigBee communication, for collection and the short range transmission of data; A part is the wireless or wire communication mode that adopts two-forty in addition, can adopt the modes such as WiFi, 3G and Ethernet, for the long-distance transmissions of network main line.
In general application system, low rate, short-range communication mode are used in the data perception and collection of front end more, use a plurality of data acquisition nodes to carry out the collection of data to a plurality of positions in short range or a plurality of parameter, afterwards, a plurality of data acquisition nodes are used the mode of wireless near field communication to transfer data to a gateway node of a localized network at its place.And this gateway node has several data transmission and the ability forwarding, one side can receive closely, the data of the node of low-speed communication network, there is again on the other hand ability remote, high-speed transfer, by using the modes such as WiFi, 3G or Ethernet to send data in the server of far-end, the data content in communication protocol also can carry out suitable conversion in the process forwarding.Far-end server also can transfer to gateway by modes such as WiFi/3G or Ethernets by the data of needs transmission, by gateway forwards to the data acquisition node closely, in low-speed communication network.Therefore,, in data transmission procedure, gateway device has just played extremely important effect in Internet of Things application system.
Because, there is more variation according to the difference of application in the process that the physical layer in network, media Access Layer and network layer data content all can be used at the network equipment in the diversity of network transmission system.In addition, because the design of each exploitation Internet of Things application system is different, host-host protocol just presents more version.In the application process of system, because instructions for use and the condition of system also often can change, in the agreement of front network or the quantity of network node of perception part, also can regularly change.In application system, through the data content in the agreement of gateway forwards, also can change due to the needs that heterogeneous networks partly transmits.
At present, in most application, the gateway device adopting is often just its function have been carried out to fixed constraints after Development and Production finishes, its conversion regime for the data division in agreement is often fixing form, and normally used mode is that the data message that system front end sensing network is gathered directly transfers to upper end network or carries out, after some fixing conversions, data message is transferred to upper end network by another communication protocol.
That is to say, the effect that most gateway plays is that the data of heterogeneous networks are forwarded, and for the forwarding form of data message, mostly is transparent transmission mode or according to fixing format transformation, agreement is changed.For the situation that front network host-host protocol changes or number of nodes of sensing network, scale etc. change, the gateway device of most can not configure neatly, gateway device can not adapt to new communication data agreement, so solution is to adjust the host-host protocol of front end sensing network and the agreement of system background process service simultaneously, the agreement of the front-end and back-end of system can be consistent, thereby can effectively complete collection and the transmission of data.
In this case, if work as the data acquisition network agreement of front end, there is variation, the protocol changes that the processing protocol of back-end services system just must conform to it, or adopt new gateway device to change the conversion regime of data protocol.Like this, will increase the workload of whole system exploitation or operation, simultaneously because needs change background service system or upgrade, the stability of system also likely can reduce.
And for Internet of Things application system, the developer of gateway and user are different often, user is determined by developer for forwarding and the conversion process of gateway protocol and data content, namely when the mode of the needed protocol forward of user or data conversion treatment mode wherein change, can only require the equipment supplier of developer or gateway to change gateway, to adapt to user's demand.The inefficiency that the gateway of this mode has just caused application system to use, and the inconvenience of user's use.
