Demonstrate,prove each intelligent display terminal ED without interference with each other.
2. the packet of AP and intelligent display terminal ED controls the amount of storage that can reduce system data.
3. broadcast wakeup function can make intelligent display terminal ED complete data communication with AP within the given time, other
The intelligent display terminal ED that need not communicate continues dormancy, to reduce system power dissipation.
4. the intelligent display terminal ED that it is administered by AP is grouped according to performance, frequency, signal strength signal intensity, to reach
Frequency misplaces, and increases antijamming capability.
Brief description
Fig. 1 is the schematic diagram of one embodiment of the present invention.
Fig. 2 is the ordering strategy schematic diagram of AP and intelligent display terminal ED in the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is made to describe into a line：
As shown in Figure 1-2, the present invention is by least one intelligent display terminal ED, at least one AP and cloud service management software
Three part compositions, using ordering strategy, broadcast wakeup, packet controls, automatic frequency-hopping technology to realize reliable and stable, anti-interference
Strong wireless bin tag system, is implemented as follows：
AP and intelligent display terminal ED adopts ordering strategy：AP specifically at least includes two groups of radio-frequency modules and at least one is fixed
When device, the first timer time of AP is divided into N decile, and the first radio-frequency module is used for and is in unregistered intelligent display terminal
ED carries out communication interaction data, and will be sent to background service management software, background service in the information of this intelligent display terminal ED
Management software analyzes and processes, if this intelligent display terminal ED is in the system, notes that AP allows this intelligent display terminal ED to note
Volume, AP distributes a timeslice to this intelligent display terminal ED, specially supplies its communication, this intelligent display terminal ED also here
Wake up from sleep state in timeslice and is communicated with AP, this communication is responsible for completing by the second radio-frequency module, thus can be by
Intelligent display terminal ED in system each to interact with AP it is ensured that intelligent display terminal ED will not according to exclusive timeslice
With timeslice have multiple seizing communication it is ensured that each intelligent display terminal ED is without interference with each other；
The Handshake Protocol of AP and intelligent display terminal ED is broadcast wakeup：AP by each timeslice broadcast come with intelligence
Display terminal ED can be shaken hands, comprised intelligent display terminal ED in broadcast the need of entering row data communication, Yi Jihe
The time of Shi Jinhang communication and communication time, upon receipt of needing data communication, intelligent display terminal ED can be given
Data communication is completed with AP in time.The intelligent display terminal ED that other need not communicate continues dormancy, to ensure low-power consumption；
The packet of AP and intelligent display terminal ED controls：Due to the need of communication only notifying an intelligent display terminal ED
Need the data volume of 1BIT, therefore can optimize and distribute M intelligent display terminal ED to piece at the same time, in this timeslice this
A little display terminals wake up, from sleep state, the broadcast message receiving AP, thus can increase the intelligent display terminal ED that AP is managed
Quantity from original N number of, expand N*M to, the data of required broadcast wakeup intelligent display terminal ED or n times, that is, each
Timeslice broadcasts all intelligent display terminal ED message of packet under this time piece.
Communicate between AP and intelligent display terminal ED and adopt automatic frequency-hopping：First institute is scanned by AP and intelligent display terminal ED
In place's environment, the RSSI value of each frequency, then will be worth uniform transmission to background service management software, background service management software
By the RSSI value situation of each frequency of analytical calculation, choose the frequency wherein meeting requirement, form list, be distributed to AP, AP
Again list is sent to intelligent display terminal ED by broadcast, ensuing communication just can be synchronized by this list
Frequency hopping, to complete the frequency of automatic tripping institute serious interference.
Listed above be only the present invention be embodied as example, the invention is not restricted to above example son, can also have
Many similar structures change designs.Those of ordinary skill in the art can directly derive from present disclosure or associate
All deformation, be all considered as protection scope of the present invention.
