Abstract
The invention provides a novel communication method for an electronic goods shelf label system. By means of dual-band communication, wireless wakeup is completed with low frequency bands while data communication is completed with high frequency bands by an electronic goods shelf label terminal, low power consumption in standby of the electronic goods shelf label terminal is guaranteed, and the service life of the electronic goods shelf label terminal is prolonged.
Description
Technical field
The present invention relates to a kind of double frequency communication means of electronic bin tag system, relate in particular to the electronic shelf label that is applied to retail, logistic industry.
Background technology
All the time, the traditional retail industry all is to adopt the papery price tag to come the display of commodity price.Along with the development of retail trade, type of merchandize constantly increases, and a large amount of demand of appraising at the current rate that frequent all kinds of advertising campaigns cause generally adopts the mode of manual amendment's price tag, and still, the manual amendment has a regular hour and postpones and error rate.Papery price tag deficiency in these areas highlights.
In order to solve above these problems, some wireless electron bin tag systems have appearred, adopt communication modes such as wireless or infrared usually.Such as, publication number is in the open file of CN1506900A, has described a kind of electronic bin tag system, and communication means adopts low frequency wireless as carrier wave, and this system has only the mode of single-frequency simplex to communicate.
But still there is following problem in the above-mentioned scheme that provides.The first, the over the horizon communication system described in the US20110025461A1 open file, this mode is vulnerable to object blocks, and communication will be affected.The second, adopt radio communication, adopt like the low frequency mode in the CN1506900A open file, need the application scenario to arrange very long low frequency coiling antenna, need carry out complicated secondary construction if implement.The 3rd, adopt high-frequency communication such as the said mode of US006108367A open file, need the very long window time to monitor usually, battery life is produced very big influence.
Summary of the invention
The present invention accomplishes in view of second problem of above-mentioned proposition.Its objective is the communication technology of the electronic bin tag system that provides a kind of, enough reduce the standby current of electronic shelf label, thus extending battery life.
In order to address the above problem, the present invention adopts the lower uhf band of frequency to carry out circuit as subcarrier and wakes up, and the higher S frequency range of employing frequency communicates as the main carrier of radio communication, and then carries out the maintenance and the demonstration of processing back realization data such as decoding.This method comprises following step:
(1) repeater obtains the notice of data server, need carry out the renewal of electronic shelf label display message, to the frequency range of waking up that lower frequency is launched at the electronic shelf label terminal of respective regions, carries out circuit and wakes up;
(2) the low frequency signals energy received of electronic shelf label terminal surpasses setting threshold, and electric pulse in generations powers on its other circuit parts, the entering listening state;
(3) listening state is received the carrier wave of upper frequency, and the terminal recognition number laggard line data that matees oneself receives.
The present invention has produced positive effect: at first, the UHF carrier wave that this electronic bin tag system frequency of utilization is lower wakes up, and the raising system is to the connection rate of dormancy label; Secondly, the present invention can effectively set the regional extent and the quantity of the label of trunking control to the setting of signal energy threshold value; At last, based on equal number of labels, the present invention has improved the service efficiency of S frequency range ISM band effectively, reduce electronic bin tag system itself in the environment for use other with the interference of frequency range equipment.
Description of drawings
Fig. 1 is that repeater of the present invention is connected synoptic diagram with electronic shelf label, and as Figure of abstract;
Fig. 2 is a uhf band wake-up step synoptic diagram of the present invention;
Fig. 3 is an electronic shelf label terminal works step synoptic diagram of the present invention.
Embodiment
Fig. 1 representes that in practical implementation, repeater is connected and communication scheme with the electronic shelf label terminal.Electronic shelf label terminal and repeater all have two antennas, are respectively applied for the transmission of uhf band and S frequency range radiowave, thereby realize waking up the operation with data transmission.
Fig. 2 representes, using uhf band to carry out the wakeup process at electronic shelf label terminal, the method that has adopted the wireless receiving energy threshold to judge.Specifically comprise the steps:
(1) energy in the UHF channel is carried out detection;
(2) carrying out signal after the detection amplifies;
According to the threshold value of budget, judge that (3) energy is during greater than setting threshold, the output starting impulse.
Fig. 3 has represented the job step at electronic shelf label terminal, and is specific as follows:
(1) standby dormancy, in order to reduce the power consumption of electronic shelf label terminating circuit, S frequency range telecommunication circuit and display process circuit are in the minimum power consumption state;
(2) after the electronic shelf label terminal receives the UHF wake-up signal greater than threshold value, produce a unbalanced pulse, main circuit is powered on, change the reception waiting status then over to;
(3) terminal recognition of data transmit-receive Circuit Matching oneself number is as through then carrying out corresponding data communication;
(4) after data communication is accomplished, the electronic shelf label terminal is sent to repeater and is confirmed request.
