Specifically, in this embodiment, consider among the daily life, along with internet technology's update, the popularization of intelligent movement end, each big electricity merchant can make a trend in advance to different festivals, the unit price of article gets off earlier in the festivals, let the user exchange money earlier through the reservation function, then the user can in time order down and purchase own commodity to the festival on the day, along with the electricity merchant influence, the entity shop also need advance with the time, the electron price is signed exactly in order to improve entity shop competitiveness. In this embodiment, a reservation updating scheme for electronic price tags is provided, that is, the prices of the commodities can be determined before the holidays, the server is allowed to issue the picture information of the commodities to all the electronic price tags through the base station in the background at the idle time in the evening, the electronic price tags are cached firstly, and the base station is allowed to update all the electronic price tags through one-time broadcasting until the current shop door in the holidays is opened. In the above embodiment of this embodiment, the base station and the electronic price tag need to implement a reservation function, and the background server also needs to implement a function of configuring a reservation time. Based on the current technical scheme, if 7000 electronic price tags need to be updated simultaneously, 1 hour is probably needed, and if no reservation function updates the electronic price tags on the holiday day, the commodity price updating delay is caused, so that the consumption experience of the user is influenced. Therefore, in this embodiment, a new image-brushing scheme with a reservation function is proposed, that is, in the above-mentioned technology, only the image information priced tomorrow is needed to be cached in advance on the flash memory of the electronic price tag or on the screen at night.
Specifically, in this embodiment, each electronic price tag receives a broadcast packet transmitted by a broadcast gateway of the base station at a reserved time; then, each electronic price tag is detected according to the price tag ID of the electronic price tag included in the broadcast packet, namely when the price tag ID is consistent with the ID of the electronic price tag, whether the current time is in the reserved time of the picture brushing operation is further determined; then, if the current moment is at the picture-brushing operation appointment time of the electronic price tag, further determining whether the electronic price tag caches picture-brushing data; and finally, if the electronic price tag caches the image brushing data required by the image brushing operation to be executed, executing local image brushing operation according to the image brushing data without initiating a connection request to the data gateway of the base station again.
Optionally, in this embodiment, the server side is utilized to freely customize multiple reservation times, so that the contents of all price tags can be updated into the price tags in advance by staff, convenience and practicability are realized, and economic disputes caused by artificial errors easily occurring in price updating on the holiday are avoided;
optionally, in this embodiment, the electronic price tag only updates the picture information cached in the local cache to the screen, the refresh time is fast, no delay is caused, and the delayed display caused by updating all the electronic price tags at the current festival is reduced.
The embodiment has the advantages that the broadcasting packet transmitted by the broadcasting gateway of the base station according to the reserved time is received; then, if the broadcast packet comprises the price tag ID of the electronic price tag, determining whether the current time is in the reserved time; then, if the current time is in the reserved time, determining whether the electronic price tag caches the image brushing data; and finally, if the electronic price tag caches the image brushing data, executing local image brushing operation according to the image brushing data. The humanized scheme for pre-drafting the electronic price tag is realized, so that the content updating efficiency of the electronic price tag is higher, the delay of content updating is reduced, the accuracy of content updating is improved, and the user experience is enhanced.
