Description
Technical field
The present invention relates to Zigbee communication technical field more particularly to a kind of communication means.
Background technology
Zigbee protocol is born in 2004, is the protocol of wireless local area network based on IEEE802.15.4 standards.Its feature
It is short distance, low complex degree, self-organizing, low-power consumption, low data rate, safe and reliable.The target of ZigBee technology is to be directed to work
Industry, home automation, remote measuring and controlling, the industries such as automotive automation, agricultural automation and medical treatment and nursing.Though ZigBee technology is
Have more than 10 years history, also begin to be widely used in industry-by-industry, but up to the present, most factories, office building and
Average family uses this kind of commodity/device not yet, that is to say, that also belongs to using the various products of the technological development at present
It is especially domestic in the starting stage, still there is extensive foreground.ZigBee equipment is broadly divided into two kinds：Full-function device FFD
(full-function devices) and half function device RFD (reduced-function devices).Full-function device energy
Enough play the part of routing/coordinator (Router/Coordinator) or terminal device (End-Device) role.
In the prior art, the FFD and RFD of existing ZigBee systems are communicated there are two types of pattern：Time slot (Beacon
Enabled, also known as beacon are enabled) communication pattern and non-temporal slot (Nonbeacon Enabled, also known as non-beacon are enabled) communication
Pattern.Both communication patterns respectively have following features：
Time slot communication pattern is using uncontested access (contention free) mechanism, and communication is by road every time
By/coordinator (FFD) initiation, will not conflict, each step takes less, also compares fixation, about 1.5ms~2.0ms.Time slot communicates
The pattern communication time is although short, but wants periodic wakeup receiving time mark post (Beacon), also increases call duration time indirectly, increases
Energy consumption, shortens the use life cycle of battery.
Non-temporal slot communication pattern using competition random access (contention based) pattern, referred to as " carrier/
Wave is intercepted multiple access conflict and is avoided " CSMA-CA (Carrier Sense Multiple Access with Collision
Avoidance access mechanism), every time communication are initiated by terminal device (RFD), and when encountering conflict, terminal device needs to wait for
Some time unit, is then initiated again, thus often step take it is less fixed, especially when a routing/coordinator have it is more
It is communicated when terminal device busy even more so.
As shown in Figures 1 to 4, the communication steps of communication means are at least 2 steps at present, and up to 5 steps, step is more, the time
Long, energy consumption is big, shortens battery life；Terminal communication can clash, and often step communication is time-consuming unstable, in multi-terminal network
It influences particularly evident.
Invention content
In view of the above-mentioned problems, a kind of communication means of the present invention has the advantages that time slot communication pattern, terminal device is not
It can conflict, communication steps are few, take less and stablize, communication process is made to become simple, while energy consumption is also reduced.

~4.0ms.Each time beat is 0.5s, and the self communication period of each terminal device 103 is up to 7.8125ms,
Then 101/ router 102 of coordinator can connect 64 equipment, ensure that it is steadily communicated；When the transmission terminal
When device data or the control data, then 101/ router 102 of the coordinator and the terminal device 103 are every 0.5s
It sends primary；And when sending the heartbeat data, then the terminal device 103 is primary every Nx0.5s transmissions, and N is described
The quantity of terminal device 103, in this way can be to avoid continually sending heartbeat data, and battery energy consumption is caused to increase, while can be with
Ensure that the terminal device 103 can obtain clock data and calculate the self communication period, ensures the accurate stable of call duration time.
Further include in the step 1：When first equipment is sent in self communication time slot to second equipment
When device data, first equipment caches the device data；
Further include in the step 2：When second equipment sends the second control data to first equipment, institute
State the second equipment caching the second control data.
Data are cached, when data send or receive process in when something goes wrong, data can be retransmitted.
Further include in the step 1：In the case where first equipment receives the first control data, described first
Equipment verifies the first control data；
If verification passes through, the first reply data is sent to second equipment；Otherwise, the heart is sent to second equipment
Hop count evidence, so that second equipment retransmits the first control data in next time beat.
Further include in the step 2：
In the case of second equipment receives the terminal device data, second equipment is to the end
End equipment data are verified；
If verification passes through, second equipment sends second reply data to first equipment；Otherwise, described
Second equipment sends the clock data to second equipment, so that first equipment retransmits the device data.
The length of the self communication time slot is at least 2.5 times that step 1 and step 2 the sum of actually take.
When first equipment is the self communication at the time of retransmitting the device data to second equipment
The median of gap.
