1. four networks one platform type gateway hardware designs
As Fig. 1, four networks one platform type gateway 10 of the present invention comprises: network connection and protocol translation functional module 1, internet module 25, bluetooth module 22, ZigBee module 23, TD-SCDMA module 24.Internet module 25 is terminal nodes of internet, and it is connected with internet network 7 by netting twine; Bluetooth module 22 is nodes of blueteeth network, and it realizes the wireless connections of gateway 10 and blueteeth network 8; ZigBee module 23 is a ZigBee network of network node, and it is responsible for the wireless connections of gateway 10 and ZigBee network 23; TD-SCDMA module 24 is a node of TD-SCDMA network, and it realizes the wireless connections of gateway 10 and TD-SCDMA network 6.Network connects and protocol translation functional module 1 realization blueteeth network 8, ZigBee network 9, being connected and the conversion of procotol of 7 any two kinds of networks of TD-SCDMA network 6 and internet.Therefore, gateway of the present invention can be realized the ZigBee network, blueteeth network, the communication in TD-SCDMA network and the internet between any two kinds of networks.
Fig. 2 is the detailed structure view of gateway 10, and the part that network connects and protocol translation functional module 1 respective dashed 12 is included comprises: 14,15,16,17,4 usb interface modules 18,19,20,21 of 13,4 double-FIFO modules of processor.Processor 13 is connected with first usb 18 by the first double-FIFO module 17 respectively, be connected with second usb 19 by the second double-FIFO module 14, be connected with the 3rd USB interface 20 by the 3rd double-FIFO module 15, be connected with the 4th USB interface 21 by the 4th double-FIFO module 16.First usb 18 is connected with the ZigBee module 23 of band USB interface, second usb 19 is connected with the TD-SCDMA module 24 of band USB interface, the 3rd USB interface 20 is connected with the internet module 25 of band USB interface, and the 4th USB interface 21 is connected with the bluetooth module 22 of band USB interface.
It is an advantage of the present invention that 4 kinds of all mixed-media network modules mixed-medias all are connected in the gateway 10 by the USB interface access way.USB interface is supported hot plug, and therefore, the combination of gateway is very convenient, and is also very flexible.If in a certain concrete application, only have wherein three or two networks, can only connect the network that needs, and unlike the mode of being integrated and connected, each mixed-media network modules mixed-media all must appear in the gateway; If certain mixed-media network modules mixed-media or protocol translation functional module have been gone bad, only need change this module and get final product, need not abandon whole gateway.
In the four networks one platform type gateway, the network that each USB interface is fixedly connected one type, the first usb 18 corresponding ZigBee networks 9 designed as the Home Network Central Shanxi Plain, second usb 1,9 corresponding TD-SCDMA networks 6, the 3rd USB interface 20 corresponding internet network 7, the four USB interface 21 corresponding blueteeth networks 8.Carry out protocol translation with Network Recognition and when being connected at processor 13, all come work according to this fixed form, for example, the data that processor 13 acquiescences pass over from first usb 18 come from the ZigBee network exactly.
Double- FIFO module 14,15,16,17 comprises transmission FIFO and receives two fifo modules of FIFO that it can cushion data, mates the communication speed of heterogeneous networks, thereby makes the network communication of smoothness smoothly of different communication speed.
2. the processing procedure of four networks one platform type gateway
The processing procedure of this gateway 10 mainly is divided into: TD-SCDMA/ZigBee communication, TD-SCDMA/ Bluetooth communication, TD-SCDMA/ Internet traffic, ZigBee/ Bluetooth communication, ZigBee/ Internet traffic, bluetooth/Internet traffic.Be example explanation communication process with TD-SCDMA/ZigBee communication only below, the method for other inter-net communication is identical.
TD-SCDMA/ZigBee communication mainly is divided into two kinds of situations:
1) TD-SCDMA network connecting request side (being masters), ZigBee network response side (being the passive side);
2) ZigBee network connecting request side (being masters), TD-SCDMA network response side (being the passive side);
For first kind of situation, workflow diagram as shown in Figure 3, its course of work is described below:
A certain node communication among some node requests and the ZigBee in the TD-SCDMA network, this node at first sends a solicited message to the TD-SCDMA module in the TD-SCDMA network, comprise address of node information in the ZigBee network in this solicited message, after the TD-SCDMA module receives this signal, send to processor, processor obtains this signal, inquire address correspondence table at first, address spaces in the solicited message is become the address of ZigBee network node, send a connection request signal (having changed into address of node in the ZigBee network) then and give the ZigBee module, the ZigBee module is forwarded to node corresponding in the ZigBee network with request signal.If the ZigBee node can carry out data communication, then the signal of an agreement communication of loopback is given processor, after processor receives this signal, just sets up a communication port between TD-SCDMA network and ZigBee network.Processor sends the successful connection signal to TD-SCDMA module and TD-SCDMA network node then, and the network node in two networks begins data communication.If the ZigBee network node is busy, then communicate to connect failure.Data communication is divided into two kinds of situations:
1) the TD-SCDMA network node sends instruction, requires the ZigBee network node to send data;
In this case, the TD-SCDMA network node at first sends instruction to the TD-SCDMA module by wireless mode, after the TD-SCDMA module receives information, to instruct transmission FIFO to send to processor by USB interface and double-FIFO, processor carries out protocol translation with instruction, reception FIFO and USB interface by the double-FIFO interface send to the ZigBee module, send to the ZigBee network node by the ZigBee module by wireless mode.The ZigBee network node sends to the TD-SCDMA network node according to the requirement of instruction with the data message that collects.TD-SCDMA does not then do any operation if successfully receive data, if receive data failure, then when connecting, can select whether to transmit again these data according to system's setting next time.If system is set to transmit again data, then have the restriction that a maximum repeats to transmit the data number of times, lasting re-transmission requires number of times to surpass this restriction, no longer requires to retransmit.
2) the TD-SCDMA network node directly sends data, requires the ZigBee network node to receive data;
In this case, the TD-SCDMA network node at first sends corresponding data to the TD-SCDMA module by wireless mode, after the TD-SCDMA module receives data, transmission FIFO by USB interface and double-FIFO sends to processor with data, processor carries out protocol translation with data, reception FIFO and USB interface by the double-FIFO interface send to the ZigBee module, send to the ZigBee network node by the ZigBee module by wireless mode.After the ZigBee network node received data, that can return a data reception condition reported to the TD-SCDMA network node.If successfully receive, then return the reception successful information, make mistakes if receive, then return the information of taking defeat, according to system's setting, can select whether to require the TD-SCDMA network to transmit data again.If system is set to transmit again data, then have the restriction that a maximum repeats to transmit the data number of times, lasting re-transmission requires number of times to surpass this restriction, and it is invalid then can to give tacit consent to connection, no longer retransmits.
Consider between certain two network and monopolize network channel for a long time, can make between other network and can not communicate by letter that this gateway is when design, when requiring any two kinds of inter-network datas to communicate by letter, a frame data end of transmission can only transmit frame data, in case must connect by interrupt network at every turn.Therefore after TD-SCDMA network node or ZigBee network node transmits frame data, processor can transmission be connected ON-and OFF-command with the ZigBee network to the TD-SCDMA network, the data communication end of TD-SCDMA network and ZigBee network.
The working method of second kind of situation also is so, and the masters of request network service that different is is the ZigBee network.
The work of gateway system is mainly controlled by processor, and it adopts the communication between a kind of cycle detection method realization all-network, flow process such as schematic diagram 4, and its working method is as follows:
Gateway at first will carry out initialization operation when powering on, it is bluetooth module, the ZigBee module, the TD-SCDMA module, internet module sends to processor with address of node information in the present networks and the address information of self, processor shines upon the all-network address of node, sets up an address correspondence table.In addition, gateway is when work, if blueteeth network when having node to insert in the ZigBee network, also can be revised corresponding address correspondence table.Processor at first detects the ZigBee network and whether asks communication (whether the transmission FIFO that is double-FIFO module 17 is non-NULL).If request is arranged, then read the data among the transmission FIFO of double-FIFO module 17, judge ZigBee network requests and which network service, communication means is communicated by letter as ZigBee/TD-SCDMA; If do not have a request or a frame information sign off, then detect blueteeth network and whether ask communication (be in the double-FIFO module 16 transmission FIFO whether be empty), if request is arranged, then read the data that double-FIFO module 16 sends among the FIFO, judge blueteeth network request and which network service, communication means is communicated by letter as ZigBee/TD-SCDMA; If do not have a request or a frame information sign off, then then detect internet network and whether ask communication (be in the double-FIFO module 15 transmission FIFO whether be empty), and then detect the TD-SCDMA network and whether ask communication (be in the double-FIFO module 14 transmission FIFO whether be empty), after four kinds of networks all detect one time, begin to detect again from the ZigBee network again, periodic duty makes and can both realize communication between four kinds of any two kinds of networks of network like this.
The right of any two kinds of inter-net communications is an equality in the gateway of the present invention, and the principle of time-sharing operation is adopted in network service in the gateway.So the efficient communication speed of gateway can reduce, this just makes the application of this gateway be only limited in the network environment of low rate communication.Therefore it is fit to man of family electrical integrated control system, want based on existing multiple network in the fields such as sensing net system and Industry Control, and only need transmit the lower field of a little information or effective transmission speed between network, the application of only communicating by letter on fixed interval point when being particularly suitable for those inter-net communications is as wireless personal local area network.
The present invention describes from the hardware configuration of gateway and working method aspect, under the situation of the spirit and scope of the invention that does not break away from the appended claims and limited, can carry out the change of form and details separately.
