The present invention encapsulates one deck SH protocol layer again on the basis of ZStack protocol stack, is mainly used in as application layer program provides data transmission interface, and carries out parsing be supplied to application layer program for receiving network packet.
In embodiments of the present invention, when application program will carry out network data transmission, first can call SH protocol layer and data transmission interface is provided, the data of application program are come in as interface parameters transmission.On Zigbee equipment, when the application data of application program is issued to Zigbee network from application layer, encapsulation process as shown in Figure 1 be experienced:
See Fig. 1, first, the application data of application program encapsulates at SH protocol layer, becomes SH Protocol layer data, and the application data of application program is by as the application data in SH Protocol layer data; Described SH Protocol layer data comprises frame head, postamble and application data, described frame head is used for store data routing iinformation, postamble is for storing checking data, and the data routing iinformation that described frame head is deposited comprises Zigbee device address, source, the target TCP/IP device address of data.
Then, SH protocol layer, using overall to SH protocol data frame head, application data and the SH protocol data postamble application data as Zigbee protocol layer, is passed to Zigbee protocol layer and again encapsulates; Finally, the data of whole Zigbee protocol layer will be sent to Zigbee telegon by Zigbee network.The application data of Zigbee protocol layer is sent to SH protocol switch by Zigbee telegon, and the application data in SH Protocol layer data according to the frame head of SH Protocol layer data and trailer information, can be forwarded to object TCP/IP equipment by SH protocol switch.
Wherein, SH protocol switch at each port monitoring reception by the packet adding specific packet header bag tail after SH protocol encapsulation.After receiving packet, cross the data type (user data or network operation data) of this packet of analysis judgment to packet header, if be network operation frame, program continues the routing address of resolving the transmission of these data of this data acquisition, increases newly the routing table in switch, upgrades; If be user data frame, the transmission types information in program meeting resolution data packet header, judge with this, this Frame be based on have the mode of link to send or based on without link mode send (have link and without link send mode just as TCP and the UDP mode of ICP/IP protocol, the mode of link is had to be exactly to ensure that data can send reliably, without the send mode of link, can not ensure that data can be sent to), after determining the send mode of data, will go to search routing table, determine transmit path, data are sent.
See Fig. 2, for Zigbee equipment a kind of in the embodiment of the present invention and TCP/IP equipment carry out the system configuration schematic diagram that communicates.System shown in Figure 2 comprises Zigbee network a, and wherein Zigbee network a comprises Zigbee equipment 1 and Zigbee equipment 2, and Zigbee network a is connected with SH protocol switch A by telegon, and SH protocol switch A is connected to TCP/IP network; TCP/IP equipment 10 and TCP/IP equipment 11 are all connected to TCP/IP network by SH protocol switch B; In system each Zigbee equipment ZStack protocol stack in be all packaged with one deck SH protocol layer.
When application layer program will to the TCP/IP network equipment (under SH protocol layer and SH protocol switch, Zigbee network equipment is equal to TCP/IP equipment) when sending data, call the data transmission interface that SH protocol layer provides, and the corresponding IP of the intended target TCP/IP network equipment, port etc., after data send, can be sent on corresponding equipment through a series of conversion and route.When TCP/IP equipment is to Zigbee equipment sending data, TCP/IP network identity according to Zigbee equipment carries out data transmission, when ZStack protocol layer receives network data, data can through SH protocol layer, packet is resolved by SH protocol layer, user data is wherein supplied to the application program of corresponding port, to corresponding application triggers AF_INCOMING_MSG_CMD event, application program takes user data away in this event handling function.
As: the Zigbee equipment 1 in Zigbee network a is for sending TCP/IP equipment 10 by data.During communication, the data of Zigbee equipment 1 are sent directly to the telegon of Zigbee network a, data are passed to SH protocol switch A(removed Zigbee protocol layer in telegon after and the application data in Zigbee protocol layer can be sent to SH protocol switch A by telegon, from the relation in Fig. 1, application data in Zigbee protocol layer is now exactly the data of whole SH protocol layer), data are sent to SH protocol switch B by TCP/IP network by the relevant information that SH protocol switch A provides according to the SH protocol layer in packet, data are routed to TCP/IP equipment 10 by the relevant information that SH protocol switch B provides according to the SH protocol layer in packet.
The embodiment of the present invention is using the ZStack protocol stack through encapsulation SH protocol layer, application layer program only needs the task by its initialization function (type function is identical with the task initialization function of former ZStack) and event handling function (event handling function of type function and former ZStack is identical) are passed to SH protocol layer provide with the form of parameter to add interface, during system cloud gray model, operating system can be application helical pitch sequence Resources allocation, and application program is carried out registering, binding with the port of specifying in application initialization function.
In Zigbee network, the node theory can held in individual network is 65535, and can support that in each Zigbee equipment the program program run is 240, and each application program is bound with the port of specifying mutually when registering.
The embodiment of the present invention adds one deck SH protocol layer in the ZStack protocol stack of each Zigbee equipment, described SH protocol layer matches with SH protocol switch, each Zigbee equipment is made to have a unique TCP/IP network identity, the present very ripe Ethernet based on ICP/IP protocol " is communicated with " with Zigbee radio sensing network phase, Zigbee net is set up for becoming a TCP/IP network equipment.Zigbee equipment and TCP/IP LA Management Room can be dependent on the unique TCP/IP network identity of each equipment and communicate.
