Abstract
The invention provides a new radio frequency self-awakening communication method applied to electronic shelf label systems, wherein in the communication method, an independent self-awakening control function is added to control a sleeping status and a working status of a radio frequency transceiving module and a microcontroller; when both the radio frequency transceiving module and the microcontroller are in the sleep status, only the self-awakening control function is remained, and the function consumes extremely low power. Therefore, the method is capable of greatly prolonging the service life of an electronic shelf label terminal so as to reduce the use cost of the electronic shelf label system.
Description
Technical field
The present invention relates to a kind of communication means that reduces the twireless radio-frequency communication system power dissipation, be particularly useful for adopting the electronic bin tag system of twireless radio-frequency communication.
Background technology
Along with the continuous development of retail business, type of merchandize is more and more, and advertising campaign is more frequent, and the management of electronic article shelf label and replacing demand constantly increase.But increasing considerably of human cost and papery electronic shelf label cost develops to retail business and brought resistance.Now, along with the application of wireless technology, the electronic bin tag system of papery electronic shelf label occurred being used for replacing, this system can revise the price of display of commodity in real time accurately.Such as; Notification number is in the patent document of CN201876908U; Mentioned a kind of electronic bin tag system, system is by a station server, a repeater; A plurality of electronic shelf labels and a portable electronic tag management devices are formed, and server is revised the price of respective electronic shelf label through repeater.This electronic bin tag system can be revised the price on the label in real time accurately, and has saved the cost of labor of changing.
In the general electronic bin tag system; In order to reduce the power consumption of electronic shelf label, generally all can upgrade and the two kinds of operating states of sleeping, in the ordinary course of things for each electronic shelf label terminal is provided with; The electronic shelf label terminal is in sleep state; When needs carry out Data Update to it, need earlier it to be waken up, and then carry out transfer of data.But the mode of waking up that traditional electronic bin price tag system adopts is the microcontroller timing wake-up, initiatively wakes up after the sleep at set intervals.When microcontroller wakes up, again wireless transport module is opened the wake-up signal of search repeater.The benefit of this kind mode is that wireless transport module is in zero current condition when microcontroller is in the state of sleep, has saved a lot of power consumptions.But when microcontroller woke up, wireless transport module also will be wanted initialization, and initialized electric current is very high, and the initialized time of while is also long, and the power consumption of this moment is very high.
Summary of the invention
The present invention is exactly in order to solve the above problems, and has proposed a kind of newly, is applied in radio-frequency module in the electronic bin tag system from waking communication means up.
The technical scheme of this communication means is; The electronic shelf label terminal has to be upgraded and the two kinds of operating states of sleeping; When the electronic shelf label terminal was in sleep state, only reservation was independently in running order from waking control module up, and other functional module all is in sleep state.Detect the wake-up signal that whether has from repeater from waking control module timing wake-up radio frequency transceiving module up; Two kinds of situation appear: first kind, if having, wake the operating state that control module can keep wireless radio frequency modules certainly up; Wake microcontroller simultaneously up; Carry out transfer of data, upgrade the displaying contents of electric paper display then, upgrading finishes then continues to get into sleep state; Second kind, if do not have, to wake control module certainly up and then can control radio frequency transceiving module entering sleep state, whole electronic shelf label terminal keeps sleep state.
The invention has the beneficial effects as follows that the microcontroller of electronic bin tag system abandoning tradition wakes mode up, adopt independently and wake control module up certainly, control the operating state at whole electronic shelf label terminal.Adopt the mode of waking control module certainly up to have and wake the lower power consumption performance of mode up, therefore can the power consumption at whole electronic shelf label terminal be remained on extremely low level than microcontroller.

Embodiment
For a better understanding of the present invention, further explain the present invention below in conjunction with accompanying drawing.
Fig. 1 representes the structure chart at electronic shelf label terminal among the present invention.The electronic shelf label terminal is by microcontroller, and the device display screen wakes control module and radio frequency transceiving module certainly up and forms.Microcontroller is responsible for the integral body control at terminal, comprises the reception and the parsing of data, the driving of electric paper display.Be responsible for timing wake-up radio frequency transceiving module detection wake-up signal and wake the renewal that microcontroller carries out electric paper display up from waking control module up.Radio frequency transceiving module is responsible for the reception and the transmission of real data.Electric paper display is responsible for the pricing information of display of commodity, and Electronic Paper has the characteristic that power down keeps displaying contents simultaneously.
Fig. 2 representes the working timing figure of electronic bin tag system.Electronic shelf label among the figure representes that partly the electronic shelf label terminal is every wakes the Tsearch time up automatically through after the length of one's sleep of Tsleep, and removal search is from the wake-up signal of repeater.Repeater among the figure is partly represented; Repeater can continue to send the wake-up signal of Twake-up time; If the electronic shelf label terminal detects this wake-up signal, need to continue the wake-up waiting signal and send completion, get into the process of transfer of data subsequently; If do not detect wake-up signal, then keep sleep state.
Fig. 3 representes the workflow diagram at electronic shelf label terminal.Generally speaking, the electronic shelf label terminal is in sleep state, and wake the detection wake-up signal every then length of one's sleep at a distance from Tsleep automatically up, if do not have wake-up signal then get back to sleep state.If detect wake-up signal, then carry out transfer of data, check then more whether transfer of data is successful; As unsuccessful, then transmit again according to retransmission mechanism, the number of transmissions determines according to set point at most; Up to transmission success, after the success, sleep state is got back at the electronic shelf label terminal.
Claims (5)
1. claim 1 has the electronic bin tag system from arousal function, and by a station server, many repeater are formed with several electronic shelf labels.
2. claim 2 has in the electronic bin tag system of arousal function, is used to show that the electronic shelf label of shelf label information need have independently from waking controlled function up.
3. waking up and communicate by letter that all to have adopted frequency be the radio wave of 2.4GHz between the claim 3, repeater and electronic shelf label.
4. claim 4, electronic bin tag system is from waking communication means up, and its step can be divided into: (1) electronic shelf label terminal is in sleep state under normal conditions, only keeps from waking controlled function up in running order; (2) wake control module timing wake-up 2.4G transport module certainly up and remove to detect wake-up signal from repeater; (3) in a single day detect wake-up signal, wake control module certainly up and microcontroller is waken up the renewal work of carrying out transfer of data and display screen; (4) transmission is accomplished, and electronic shelf label gets into sleep state.
5. claim 5, based in the claim 4 wake communication means certainly up, repeater needs to continue to send a period of time when sending wake-up signal, to guarantee that the electronic shelf label terminal is waken up.
