The MAC load that frame load is constituted, and the postamble constituted is verified by FCS.
Superframe description field defines super-frame durations, active period duration, contention access window duration；
GTS distribution release information describes the distribution condition that non-competing access-hours ensure time slot.
When specific implementation:
Step 1: the network in order to construct a tree topology needs global function and simplifies both equipment of function.
The difference of both equipment is as follows: can lead between full-function device and between full-function device and reduced function device
Letter；It cannot be communicated between reduced function device.When constructing network, chooses full-function device and (concentrated as network coordinator
Device).Whole network and a pan-id are identified by the way that a network name is arranged to concentrator to identify each sub-network, are such as schemed
1.Only the equipment with identical network name can be just added in the same network.Then, concentrator is set to neighbouring other
It is standby to send beacon frame, the structure of beacon frame such as Fig. 2 in a broadcast manner.Superframe description field defines super-frame durations, work
Jump window duration, contention access window duration；Ensure that time slot (GTS) distribution release information describes non-competing access
The distribution condition of period guarantee time slot；It include network name information in beacon frame load data.It, can in order to improve the utilization rate of channel
Not distribute the non-competing period, the Channel Access Mechanism of data all so is all timeslot-based CSMA/CA channel access machine
System, such as Fig. 3.Beacon frame is sent in first time slot of superframe, the structure of superframe such as Fig. 4.
Step 2: other full-function devices (ammeter) are when receiving the beacon frame of concentrator transmission in network, first
The network name whether network name for including in load data in beacon frame configures with oneself can be inquired to match.If matching, ammeter
Request can then be sent, the data frame of network is added to concentrator, the claim frame of networking such as Fig. 5.If concentrator allows the ammeter to add
Enter, then concentrator can be added in neighbor list using the ammeter as node, becomes one of the network from equipment.Net is added
Data exchange process such as Fig. 6 when network.In network, often there is more than one concentrator, an ammeter may receive simultaneously
The beacon frame of multiple concentrators.On the one hand, ammeter can be allowed to choose oneself according to the size of the beacon frame signal intensity received
Which it is added under concentrator.On the other hand, ammeter is added in the data frame that network is added in the request that can be sent in ammeter to answer
The logical device name being arranged with layer, concentrator can be according to the logical device names in the claim frame received to determine whether allowing the electricity
Network is added in table, ensures that ammeter is added under specified concentrator in this way.By the way that above-mentioned networking Rule of judgment is added
Afterwards, it can effectively control M1 and M2 and pan-id1 concentrator is added, pan-id2 concentrator, such as Fig. 1 is added in M3.
Step 3: the ammeter for having been added to network can also periodically send and be associated with the identical beacon frame of concentrator.
Other cannot receive the candidate device of concentrator beacon frame, if the beacon frame of this ammeter can be received, can pass through this
Network is added in platform ammeter.It can be global function by the slave equipment that network is added as father node for already present ammeter to set
It is standby, it is also possible to simplify function device.Ammeter can continue to send beacon frame to allow other equipment to be added as full-function device
Network.Network can be added in M4 by M3 as shown in figure 1, and then M4 can continue to send beacon frame, allow other equipment to be added.
Indoor manipulation unit cannot be further continued for sending beacon frame, can only communicate with the father node of oneself as function device is simplified.Generally
In the case of, an ammeter is not intended to indoor manipulation unit directly as concentrator all only equipped with an indoor manipulation unit
Child node, such as Fig. 1.So can be by requesting patrolling in the data frame that network is added by judgement described in step 2
Collect the addition network condition that implementor name carrys out manipulation unit in control room.Network is added when indoor manipulation unit directly transmits request
When data frame is to concentrator, concentrator directly refuses its addition.When some wants to pass through with the indoor manipulation unit that ammeter does not match
When network is added in the ammeter, ammeter can also refuse its addition.
Various embodiments of the present invention are described above, above description is exemplary, and non-exclusive, and
It is not limited to disclosed each embodiment.Without departing from the scope and spirit of illustrated each embodiment, for this skill
Many modifications and changes are obvious for the those of ordinary skill in art field.
