Description
Technical Field
The present invention relates to the field of mobile communications, and in particular, to a method and apparatus for electronic price tag reservation and image brushing, and a computer readable storage medium.
Background
The electronic price tag system comprises a background server, a base station and an electronic price tag terminal. The background server is used as a producer of an information source and is responsible for generating picture resources; the base station is used as a transfer medium and is responsible for transmitting the picture resources to the electronic price tag in a short-distance communication mode (such as Bluetooth or private 2.4G protocol); the electronic price tag is used as a terminal and is responsible for receiving the picture and displaying the picture to a user.
The pictures of the server sometimes need to be immediately presented to the user, for example, if a commodity in a supermarket is subjected to price adjustment, the price pictures on the electronic price tag need to be immediately updated; however, some scenes are not immediately displayed, but are delayed, for example, a holiday, a merchant is about to do an activity, the activity price is effective at a certain moment, and price tags of a large number of commodities are changed simultaneously.
Aiming at the requirement of delayed drawing of the electronic price tag, namely reservation drawing, the existing scheme is that the picture is transmitted to the electronic price tag for caching in advance, after the drawing brushing time is up, a base station initiates a display notice, and the cached picture is refreshed on a screen after the price tag receives the notice. The scheme can meet the requirements of most commercial superenvironments. However, for other scenarios, for example, the base station has a problem before the time of reserving the drawing, and some institutions such as temple will take the electronic price tag as the souvenir of their institutions (the electronic price tag is essentially, but the appearance can be of various types), send the electronic price tag to members, and need the price tag to display different contents every day (for example, display different momordica every day), so the electronic price tag is selected as the core of the souvenir, mainly because the electronic price tag is of a low-power design, and the battery can meet the power consumption requirement of 2-3 years. Under the application scene, after the member holds the souvenir and returns home, the member is separated from the environment of the base station, and the base station cannot give a command to give the price tag to display the reservation map.

Based on the above mobile terminal hardware structure, various embodiments of the method of the present invention are provided.
FIG. 2 is a first flowchart of the electronic price tag reservation brush method of the present invention. The embodiment provides a method for brushing an electronic price tag reservation, which comprises the following steps:
s1, after a base station receives picture resources to be reserved and displayed, which are sent by a server, generating a picture pushing task to be reserved and displayed, and discharging the picture pushing task into a scheduling queue of the base station;
s2, when the base station dispatches the current picture pushing task according to the dispatching queue, calculating to obtain the delay display time of the electronic price tag corresponding to the picture resource according to the current time and the reserved display time contained in the picture pushing task;
and S3, transmitting the picture resource and the delay display time to the electronic price tag through the base station, so that the electronic price tag takes the delay display time as a starting value of own delay picture brushing time, and updating the delay picture brushing time when the electronic price tag wakes up each time until the delay picture brushing time is less than or equal to zero, and displaying the picture resource.
Referring to fig. 10, in this embodiment, a server generates all picture resources to be reserved for display, pushes the picture resources to a base station, and the base station arranges the picture pushing tasks into its own scheduling queue, where each picture pushing task includes several key elements: task ID, picture resource, price tag ID, reservation display time. When the base station dispatches a certain picture pushing task, calculating the time of delayed display of the bidding price according to the current time and the reservation time, transmitting the delay time to the price when the base station transmits the picture to the price, caching the reservation picture to a flash by the price, setting delay picture brushing time DelayTime for the picture, and subtracting the awakening period from DelayTime to update the value after each awakening of the price. When the delay brushing time DelayTime is less than or equal to 0, the picture is immediately displayed on the price tag screen.
Referring to fig. 3, optionally, after receiving a picture resource to be reserved and displayed sent by a server, the base station generates a push-graph task to be reserved and displayed, and queues the push-graph task into its own scheduling queue, including:
s11, the base station receives the picture resources to be reserved and displayed by the electronic price tags through a TCP/IP communication protocol;
s12, creating the image pushing task corresponding to each electronic price according to the task ID, the image resource index, the price ID and the reserved display time of each electronic price.
Referring to fig. 4, optionally, when the base station schedules the current push-map task according to the scheduling queue, calculating, according to the current time and the reserved display time included in the push-map task, a delay display time of the electronic price tag corresponding to the push-map task for the picture resource, including:
s21, the base station dispatches the current electronic price tag and the corresponding map pushing task according to the task ID and the dispatching queue;
s22, taking the difference value between the reserved display time and the current time as the delay display time.
Referring to fig. 5, optionally, the transmitting, by the base station, the picture resource and the delay display time to the electronic price tag, so that the electronic price tag uses the delay display time as a start value of a delay brushing time of the electronic price tag, and updates the delay brushing time when the electronic price tag wakes up each time until the delay brushing time is less than or equal to zero, where brushing the picture resource includes:
s31, the base station transmits the picture resource and the delay display time to the electronic price tag through a 2.4G communication protocol;
and S32, caching the picture resource and the delay display time by the electronic price tag.
Referring to fig. 11, in this embodiment, a server provides webUI (interactive interface at a web page end) for a user, so that the user can conveniently generate or import a picture resource, and send the picture resource to a base station. In this embodiment, considering that the transmission speed of the TCP/IP connection is far faster than that of the 2.4G protocol, and that the base station and the server both supply power for the wired power supply, no low power consumption mode is required, and the processing delay is small, the present embodiment uses the base station as a buffer, and needs to buffer the picture received from the server to the local first, and establish a database to save the image_task to wait for scheduling. The image_task is used as a basic unit of scheduling, key information such as a task Id, a picture resource index, a price tag Id, a reserved picture brushing time and the like is stored, and meanwhile, the image_task is also a basic unit of data transmission between the base station and the price tag. Based on this, the base station sequentially selects one task from the scheduling queue and then transmits the picture resource to the price tag using the 2.4G communication protocol. The price tag may leave the coverage area of the base station, and at this time, the price tag cannot synchronize the system time from the base station, so the price tag cannot know the current date and time, and therefore the reservation display time, such as 2022.12.5 15:05:25, cannot be directly transmitted to the price tag, but the base station calculates the delay time, and the delay time=the reservation time-current time. The base station communicates the delay time to the price tag.
Referring to fig. 6, optionally, the method further includes:
s41, after the electronic price tag leaves the coverage area of the base station, waking up according to a preset wake-up period;
s42, judging whether the delay brushing time is equal to 0xFFFFFF or not when the electronic price tag wakes up.
Referring to fig. 7, optionally, the method further includes:
s43, when the delay brushing time is equal to 0xFFFFFF, the electronic price tag enters dormancy again;
and S44, when the delay brushing time is not equal to 0xFFFFFF, taking the difference value between the delay brushing time and the wake-up period as the updated delay brushing time.
Referring to fig. 8, optionally, the method further includes:
s45, judging whether the updated delay map brushing time is smaller than or equal to zero;
and S46, when the updated delay brushing time is greater than zero, the electronic price tag enters dormancy again.
Referring to fig. 9, optionally, the method further includes:
s47, when the updated delay picture brushing time is less than or equal to zero, the picture brushing display the picture resource;
and S48, releasing the picture resource and caching the delay display time.
Referring to fig. 12, in this embodiment, a certain flash space is required when the electronic price tag caches the picture, and the cache map and the delay display time delay time are managed. The price tag is used as a low-power-consumption product, and is in a long sleep state after leaving the coverage area of the base station, the wake-up period is about 1-2 hours, after the price tag is waken-up, delayTime is required to be updated, whether overtime is generated or not is judged, if overtime is generated, the screen is immediately brushed, and the flash space of the picture cache is released.
It should be noted that, for comparison of the reservation push map and the conventional real-time push map in this embodiment: the reservation pushing picture is to push the picture into the price tag in advance, and the picture is displayed on a price tag screen until a preset moment; and the real-time pushing is to push the pictures to the price tag and then display the pictures in real time. Both targets want to display a picture on the price tag screen at a certain moment. When the number of price tags under the base station is small, the effect of the price tags is not obviously different, but when the number of price tags is large, the image pushing task queue of the base station is long, the real-time image pushing effect is difficult to achieve to be expected, for example, the user 12:00 sends out the image pushing task, the image pushing task is queued in the scheduling queue of the base station, and the image pushing task can be scheduled only when the number of price tags is 12:05, namely, the image is refreshed only after 5 minutes. The picture can be refreshed to the screen within 5 seconds of the reserved time by reserving the push picture.
To supplement this, the timing error for the subscription profile scheme is: in this embodiment, the check of the reserved time is placed on the price tag side, and thus, it is checked whether the delay display time delay time is timed out after each wakeup, and thus, the timing error depends on the wakeup period S of the price tag, and the timing error range is [0,S ].
