Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1~7, in the embodiment of the present invention, a kind of electricity based on ZigBee and WiFi protocol realization redundancy networking
Sub- price tag system, overall system design scheme are as shown in Fig. 1.
In figure, electronic shelf label 1 is distributed on the shelf 2 that quotient surpasses, using wireless between coordinator 3 and electronics price tag 2
Communication mode sets up cordless communication network, and communication protocol is improved Zigbee protocol.Meanwhile between coordinator 3 and base station 4,
Cordless communication network is set up by WiFi agreement, Ethernet is set up by wired mode between base station 4 and host computer server 5.
Server 5 installs price control software, is managed to the merchandise news of electronics price tag, when merchandise news needs to change, on
Position machine price control software changes information by Web Publishing, after corresponding electronic shelf label 1 receives information, carries out corresponding
Modification.
(2) the bis- protocol redundancy networkings of ZigBee and WiFi.
Electronics price tag demanding terminal low power dissipation design, it is suitable to be realized with Zigbee protocol, but in practical applications, node
Theoretical quantity is not achieved in number；WiFi agreement can be used for the realization of complex task, transmit a large amount of information, but number of terminal nodes
It is limited to 100 or so.Therefore, the present invention combines both, and realizes redundancy networking.
As shown in Fig. 1, between coordinator 3 and base station 4, cordless communication network is set up by WiFi agreement, can be transmitted big
The data of amount, network transmission are more unobstructed；It is set up wirelessly between coordinator 3 and electronics price tag 2 using improved Zigbee protocol
Communication network, terminal node quantity is up to thousands of, and terminal can realize low power dissipation design.Such mode can make terminal section
Points reach hundreds of thousands of, and network data transmission is not easy to block, and compensate for and use Zigbee protocol or WiFi agreement not merely
Foot.
(3) double protocol terminal designs.
Using Zigbee protocol is used between WiFi agreement, with electronics price tag 4 between coordinator 3 and base station 4, therefore, point
Terminal module that Cai Yong be not different designs.Electronics price tag 4 is designed using ZigBee module.
Server is the WEB server based on APACHE or TOMCAT.
The working principle of the invention is: a kind of electronic bin tag system for retail business of the present invention, uses
Two kinds of wireless communication protocols (Zigbee/WiFi) are combined to the completely new approach of networking.
Wherein, the hardware design block diagram of coordinator is as shown in Fig. 2, is mainly made of WiFi module and ZigBee module.
Suitable chip is chosen for ZigBee module and WiFi module and carries out networking, while adapting to system super low-power consumption, is reduced
Conversion time between mode is further reduced the consumption of energy.Electronic shelf label terminal uses the side of various modes conversion
Method, state of activation, dormant state etc., by dormant state reduce tag power consumption, thus the selection of label chip be also energy consumption it is low,
It is cheap and better performances.
Fig. 3 is coordinator node control flow chart, and coordinator node is responsible for the transmitting of the maintenance and management information of network, first
A network is first established, whether detection node number has increase and decrease, if there is commodity before new commodity or undercarriage, then electronic bin
The quantity of label can change.If change occurs in quantity, network is re-established, and carries out price judgement later, price does not change back to
Previous step, network do not update, and price, which changes, sends new price updating data.
Fig. 4 show router node control flow chart, and router node is by updating routing table and testing goal address
To be responsible for the transmitting of data.The design cycle of the electronic shelf label node of Fig. 5 can keep low-power consumption, and the most of the time is in
Sleep state, data update are waken up, and the completion of more new data is again introduced into sleep state.
Electronic shelf label node battery predictor formula:In formula, TdIndicate section
Put the number of days that can work, QbIndicate available battery capacity, TwIndicate operating time in each cycle, TsSleep time in each cycle, IwTable
Show operating current, IsIndicate quiescent current.
Show that each terminal receives by the relationship between the power consumption and propagation delay time to electronic shelf label terminal node
The average loss power of one packet:Wherein Px
Indicate that the consumption power under sleep state, Prx indicate the power consumed under reception state, what Pt was indicated is consumed under idle state
Power, Ptx indicates that the power that consumes under transmission state, Tw indicate that transceiver switchs to required for idle state from sleep state
Time, Ti indicate to be in idle condition the lower time, and Tc indicates control packet transmission time, Tx indicate to be under sleep state when
Between, Td indicates that packet transmission time, Tt indicate that transmission state and reception state are mutually converted the required time, and L expression connects
Receive the period of a data packet.
In formulaWhat is indicated is to be powered and receive control packet in sleep and idle state lower node to be consumed
Power.It indicates to send a control packet and receives power consumed by a data packet.This
Processor of the patent using the ATmega128rfal chip of super low-power consumption as electronic shelf label.
Data transfers are huge, and the data that main controller is sent are sent out by base station uniform transmission to coordinator, then by coordinator
It is sent to terminal node.Coordinator data receiver process such as Fig. 6 configures serial ports parameter under coordinator normal operation first and beats
It opens, determines whether data receive, if receiving data placing buffer area, then start serial ports and receive data, determine whether to receive
Data are completed, and completion is only received, and can just be executed to main controller and be sent success status, at the transmitting-receiving agreement of formulation
Reason.
Data transmission flow such as Fig. 7 of coordinator, coordinator receive the data of main controller transmission, then carry out destination address pair
The terminal node answered sends data, receives deletion and has sent data, does not increase then the frequency of failure 1 time, when reaching setup failed
Maximum times illustrate that node leaves network, such as Fig. 4, and network needs to update, and do not reach number, cycle criterion are carried out, until receiving
Information is deleted in response or frequency of failure maximum updates network.
