A kind of dual-mode equipment of supporting purple honeybee and bluetooth can be divided into communication and use occasion: but single net, two net and network selection.Single net refers in the communication occasion scope of equipment only have the equipment of supporting purple honeybee or the equipment of supporting bluetooth; Two nets refer in the communication occasion scope of equipment to have the equipment of supporting purple honeybee, also have the equipment of supporting bluetooth; But network selection refers to have the equipment of supporting purple honeybee and bluetooth simultaneously in the communication occasion scope of equipment.
Dual-mode equipment carries out power management with reference to following principle: in single net, and the idle purple honeybee of this device sleeps or bluetooth module and related hardware; In two nets, press communications protocol separately, manage purple honeybee or bluetooth module and related hardware; But in network selection, according to using scene and application, select transmission network efficiently, dormancy is operational module not.Under two purple honeybee patterns,, then can select to close the respective nodes and the purple honeybee role device of one of them ZigBee network if there is no need to set up two ZigBee networks.
Under single purple honeybee pattern or single bluetooth mode, carry out separately according to bluetooth or ZigBee protocol that network is set up and node adds, route forms and maintenance, and flow process such as transfer of data.Under purple honeybee and bluetooth mode, can select according to operating position, can adopt timesharing and real-time network mode to carry out network management: the time share network mode is on the Industrial Scientific Medical ISM band of 2.4G, and ZigBee protocol and Bluetooth protocol use and supervising the network in turn; The real-time network mode is that ZigBee protocol and Bluetooth protocol use and supervising the network simultaneously on the Industrial Scientific Medical ISM band of 2.4G.Under the time share network mode, utilize global clock and arbitration mechanism, select time-sharing format and strategy.For example: purple honeybee and bluetooth mode use the time share network mode down, can be divided into continuous timeslice the service time of purple honeybee and blueteeth network, node under purple honeybee and the bluetooth determines whether to use the special time sheet according to the global clock that two role device provide, and purple honeybee and blueteeth network can use in turn; If purple honeybee and blueteeth network are according to the specific (special) requirements (as real-time) of using, need to use continuously or for a long time total 2.4G frequency range, then need to file an application, and arbitrate according to the operating position of purple honeybee and blueteeth network by two role device to two role device; If confirmation request is then repartitioned their service time of scope and at interval.
Under purple honeybee and bluetooth mode, if the application of purple honeybee and blueteeth network itself is just relevant, as the data correlation, then can determine the utilization rate of two networks according to the practical application characteristics, be responsible for continuous acquisition data in a small amount such as ZigBee network, when data accumulation arrives to a certain degree, re-use blueteeth network data are outwards transmitted.So just form, ZigBee network is long and short at interval service time, and blueteeth network relatively shorter and long at interval network handling characteristics service time.
Under the real-time network mode, purple honeybee and Bluetooth protocol use and supervising the network simultaneously; Because ZigBee protocol and Bluetooth protocol are taked the communication mechanism of direct sequence spread spectrum (DSSS) and frequency-hopping spread spectrum (FHSS) respectively on the Industrial Scientific Medical ISM band of 2.4G.If purple honeybee and Bluetooth protocol use simultaneously, then may bump, purple honeybee equipment is very little to the interference of bluetooth equipment, bluetooth equipment has certain influence to purple honeybee equipment.If the packet error rate of purple honeybee equipment (PER, Packet Error Rate) is higher than certain threshold values, then can be switched to the time share network mode.But in two nets and network selection, if bump in purple honeybee and the blue-teeth data transport process, then purple honeybee role device is selected transmits data packets again according to actual needs.
Under purple honeybee and bluetooth mode, take routing algorithm based on ZigBee protocol.If there are two role device, then this equipment should be to this its pair of network registry role's device type, and routing algorithm is with this reference as the selection route.For this reason, in the using standard Profile and routing table of purple honeybee, should increase the device type explanation of two role device.
Under purple honeybee and bluetooth mode, just like the lower network way to manage (ZB wherein, BT represents purple honeybee role device and bluetooth role device respectively; PAN ZB and PAN BT represent the ZigBee network and the blueteeth network of formation respectively):
◆ set up network and add network, with reference to figure 6;
Step 60: beginning;
Step 61: purple honeybee role device ZB scanning is also selected clean channel, sets up ZigBee network PAN ZB;
Step 62: if there is purple honeybee node C, application adds ZigBee network PAN ZB, if having then execution in step 63; Otherwise, execution in step 64;
Step 63: whether node C passes through the authentication of PAN ZB, if pass through then execution in step 65; Otherwise, execution in step 611;
Step 64: node C detects and has or not bluetooth service and other no bluetooth equipments, if having then execution in step 68; Otherwise, execution in step 610;
Step 65: node C adds PAN ZB, execution in step 66;
Step 66: whether node C contains bluetooth module, if having then execution in step 67, otherwise, execution in step 611;
Step 67: node C registers its device type, execution in step 64 to ZigBee network and blueteeth network;
Step 68: whether node C sets up according to application need and adds blueteeth network, execution in step 69 then if desired, otherwise, execution in step 610; According to application need is exactly using standard and application scenarios according to bluetooth or purple honeybee, determines whether to set up and add blueteeth network; For example:, can transmit by blueteeth network if there is multi-medium data in the network;
Step 69: node C connects with bluetooth equipment by beep-page message (Page Message) or query messages thereafter (Inquiry message), forms blueteeth network PANBT, execution in step 611;
Step 610: node C enters to hold concurrently and listens pattern (Sniff Mode);
Step 611: finish.
◆ deviated from network
1. as if the purple honeybee role device ZB of terminal equipment, normal deviated from network then sends leave group message to its father node; If this equipment is two role device, then in network, nullify its corresponding routing iinformation content; After if the father node of purple honeybee role device ZB sends the message that needs to confirm, do not obtain the affirmation information of its child node within a certain period of time, then the ZB father node is thought that this node is improper and is left, and nullifies its routing iinformation content; After leaving, the purple honeybee role device ZB of terminal equipment enters dormancy or closed condition.
2. if the purple honeybee role device ZB of router, normal deviated from network, according to actual conditions, two kinds of processing modes can be arranged: the telegon by ZigBee network is reassigned alternate router, other correlator nodes directly add this alternate router, perhaps other correlator nodes networking more voluntarily.If the improper deviated from network of ZB, then other correlator nodes networking more voluntarily; After leaving, the purple honeybee role device ZB of terminal equipment enters dormancy or closed condition.
3. if the purple honeybee role device ZB of telegon, normal deviated from network has two kinds of processing modes: by the telegon of ZigBee network reassign telegon, order its down child node add; Perhaps, perhaps its child node networking voluntarily down.
In two role device,, need to nullify its corresponding routing iinformation content if purple honeybee role device is left ZigBee network; If purple honeybee role device is left, the bluetooth role device is not left, and then mode of operation switches to single bluetooth mode by purple honeybee and bluetooth mode of operation; If just the bluetooth role device is left, then enter single purple honeybee pattern; No matter the sort of situation needs to nullify the relevant routing iinformation of two role device.
◆ data route and transmission
Under purple honeybee and bluetooth mode, the routing management of whole network is by the routing management based on ZigBee network, in conjunction with the routing mode of blueteeth network.Here the route of indication is the route between the node of optional all composition networks off the net, comprise between the purple honeybee node, and between the bluetooth nodes, the route between purple honeybee and the bluetooth nodes.Because two role device are owing to the route that has participated in simultaneously at ZigBee network and blueteeth network, therefore can be formed in the route mapping between ZigBee network and the blueteeth network, thereby can further enlarge original route scope, improve route robustness and data transmission efficiency.
With reference to figure 5, in the present invention, there is route between two nodes, claim two nodes to reach; Otherwise, claim that two nodes are unreachable.In Fig. 5, establish arrow "-" and represent to reach by two nodes about this symbol; ZB A, ZB B, ZB C are the expression symbols of purple honeybee role device; BT A, BT B, BT C, BT D, BT E are the expression symbols of bluetooth role device; ZB/BT A, ZB/BT B, ZB/BT C are the expression symbols of two role device of purple honeybee and bluetooth.With reference to figure 5, generally speaking, between purple honeybee node and the bluetooth nodes and they separately between, existing five kinds may routing relation: 1. purple honeybee node is unreachable, as ZB A and ZB D; 2. bluetooth nodes can reach, as BT B and BT C; 3. purple honeybee bluetooth nodes is unreachable, as ZB B and BT D; 4. purple honeybee node can reach, ZB/BT A and ZB/BT B; 5. bluetooth nodes is unreachable, as BT A and BT E.
Optional off the net, the route that two role device can be set up between ZigBee network and blueteeth network is related, makes original inaccessible situation might become and can reach, and makes the situation that can reach might improve its real time of data transmission and throughput.
For example, in Fig. 5, suppose not have route between ZB A and the ZB D, off the netly may form route optional, as ZB A-ZB/BT A-BT B-BT C-ZB/BT C-ZB D.Bluetooth nodes and purple honeybee node also may become and can reach.In Fig. 5, can pass through ZB B-between ZB B and the BT D〉ZB/BT A-〉BT B-〉ZB/BT C-〉BT D realizes route.In like manner, if two bluetooth nodes are unreachable, then might become and to reach.In Fig. 5, there is not route between BT A and the BT E, then off the netly may form route, as BT A-optional〉ZB/BTA-〉ZB C-〉ZB/BT C-〉BT E.
But its corresponding routing table content in network selection comprises following form: destination node, next node, next node type, power supply state, transfer of data frequency and content, channel quality, destination node distance etc.
Under two purple honeybee patterns, dual-mode equipment can add the ZigBee network of two different channels simultaneously, does not disturb each other.PAN ID represents the unique identification number of a territory net (PAN, Personal AreaNetwork); The first territory net is the individual territory net that is established at first, and the unique identification of this territory net is counted PAN ID and is made as PAN A; The second territory net is the individual territory net of being set up in order to improve network concurrency and network transfer speeds by the node in the net of first territory, and the unique identification of this territory net is counted PAN ID and is made as PAN B.If dual-mode equipment under two purple honeybee patterns, has following network activity:
