Description

Technical Field

[0001] This invention relates to the field of electronic paper technology, and in particular to an electronic paper tag monitoring method, apparatus, device, and storage medium. Background Technology

[0002] In the field of e-paper tag applications, to achieve low-power communication, e-paper tags are typically used as periodically activated listening windows, with one base station updating hundreds or thousands of tags. However, this method of updating hundreds or thousands of tags using a single base station requires the e-paper tag to maintain high power consumption in order to connect to the tag and complete the image refresh as quickly as possible when the base station initiates a connection.

[0003] The two key parameters for e-paper tag monitoring are the window and the interval. The window is the monitoring window, and the interval is the distance between two windows. To achieve low power consumption, the window duration needs to be as small as possible, and the interval as large as possible. However, in current practice, the window cannot be infinitely small, otherwise the base station will not be able to wake up the e-paper tag; while increasing the interval can reduce the power consumption of the e-paper tag, a large interval will result in a long time for the base station to wake up the tag. Summary of the Invention

[0004] This invention provides an electronic paper tag monitoring method, apparatus, device, and storage medium, which can reduce the power consumption of electronic paper tags and quickly wake up electronic paper tags and respond to connections.

[0005] To address the aforementioned technical problems, this invention provides an electronic paper tag monitoring method, comprising:

[0006] The electronic paper tag is controlled to be in an idle listening state.

[0007] When the electronic paper tag receives a wake-up command packet from the base station, it parses the wake-up command packet; wherein, the wake-up command packet includes the target tag ID and the target monitoring level;

[0008] Determine whether the target tag ID parsed from the wake-up command packet is the same as the ID of the electronic paper tag;

[0009] If the target tag ID is the same as the electronic paper tag ID, then the electronic paper tag is woken up and a connection is initiated;

[0010] If the target tag ID is different from the electronic paper tag ID, then the monitoring level of the electronic paper tag is switched to the target monitoring level.

[0011] Furthermore, the wake-up command packet issued by the base station specifically includes:

[0012] When the base station needs to initiate image scanning, it determines the target tag ID to be the electronic paper tag ID that needs to be woken up, and determines the target listening level to be the level that the electronic paper tag that does not need to be woken up needs to switch to.

[0013] Generate a wake-up command packet based on the target tag ID and the target monitoring level;

[0014] The wake-up command packet is broadcast to electronic paper tags within a preset coverage area.

[0017] For the ready listening state, set the first listening level;

[0018] For the aforementioned idle listening state, a second listening level, a third listening level, and a fourth listening level are set respectively;

[0019] When the electronic paper tag is in an idle listening state, the listening level of the electronic paper tag is determined from the second listening level, the third listening level, and the fourth listening level according to the scenario requirements.

[0020] Furthermore, the monitoring level of the electronic paper tag is switched to the target monitoring level, specifically as follows:

[0024] Historical scenario requirements are obtained, and the listening window length and window interval of the first listening level, the second listening level, the third listening level and the fourth listening level are determined through preset listening tests;

[0025] Based on the monitoring window length and window interval, the monitoring power consumption of the first monitoring level, the second monitoring level, the third monitoring level, and the fourth monitoring level is determined by the power consumption monitoring device.

[0026] This invention also provides an electronic paper tag monitoring device, comprising: a control module, a parsing module, a judgment module, a first response module, and a second response module;

[0031] The second response module is used to switch the monitoring level of the electronic paper tag to the target monitoring level if the target tag ID is different from the electronic paper tag ID.

[0032] Furthermore, the parsing module includes: a determining unit, a generating unit, and a sending unit;

[0049] Figure 5 This is a schematic diagram of one embodiment of the electronic paper tag listening device provided by the present invention. Detailed Implementation

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] See Figure 1 This is a flowchart illustrating an embodiment of the electronic paper tag monitoring method provided by the present invention. The method includes steps 101 to 105, each step being as follows:

[0052] Step 101: Control the working state of the electronic paper tag to idle listening state.

[0053] Furthermore, in this embodiment of the invention, the electronic paper tag is controlled to operate in an idle listening state, specifically as follows:

[0054] The electronic paper tag's working states include a ready listening state and an idle listening state;

[0055] For the ready listening state, set the first listening level;

[0056] For the aforementioned idle listening state, a second listening level, a third listening level, and a fourth listening level are set respectively;

[0057] When the electronic paper tag is in an idle listening state, the listening level of the electronic paper tag is determined from the second listening level, the third listening level, and the fourth listening level according to the scenario requirements.

[0058] In this embodiment of the invention, the working state of the electronic paper tag includes a ready listening state and an idle listening state. For the ready listening state, a first listening level is set. When the electronic paper tag is in the first listening level, the tag is listening at full speed, which can quickly receive connection instructions and establish a connection, thus achieving rapid wake-up. For the idle listening state, three listening levels, namely a second, a third, and a fourth listening level, are set according to different scenario requirements. By setting four listening levels through different combinations of parameters, most scenario requirements can be met.

[0059] Furthermore, in this embodiment of the invention, the monitoring level of the electronic paper tag is specifically as follows:

[0060] The monitoring levels of the electronic paper tag include a first monitoring level, a second monitoring level, a third monitoring level, and a fourth monitoring level;

[0061] Historical scenario requirements are obtained, and the listening window length and window interval of the first listening level, the second listening level, the third listening level and the fourth listening level are determined through preset listening tests;

[0062] Based on the monitoring window length and window interval, the monitoring power consumption of the first monitoring level, the second monitoring level, the third monitoring level, and the fourth monitoring level is determined by the power consumption monitoring device.

[0063] In this embodiment of the invention, low-power wireless communication technology is used to achieve low-power communication for electronic paper tags. See also Figure 2 This is a schematic diagram of a monitoring window provided by the present invention. When the window duration is as short as possible and the interval is as large as possible, the power consumption of the electronic paper tag can be kept low. However, since the window cannot be infinitely small in reality, otherwise the base station would not be able to wake up the electronic paper tag, increasing the interval can reduce the power consumption of the electronic paper tag, but if it is too large, the time for the base station to wake up the tag will become very long. Therefore, it is necessary to determine the window length parameters and interval parameters for each monitoring level through testing. With the parameters determined, the monitoring power consumption of each monitoring level can be obtained through a power monitoring device. See also... Figure 3 This diagram illustrates the determination of monitoring level parameters provided by the present invention. S1 represents the first monitoring level in the ready monitoring state, while S2, S3, and S4 represent monitoring levels formed by different parameter combinations in the spatial monitoring state. When the electronic paper tag is in the spatial monitoring state, the monitoring level can be set according to the scenario requirements. For example, if power consumption requirements are high, the monitoring level can be set to S4, followed by S3, and finally S2.

[0064] Step 102: When the electronic paper tag receives a wake-up command packet from the base station, it parses the wake-up command packet; wherein, the wake-up command packet includes the target tag ID and the target monitoring level.

[0065] Furthermore, in this embodiment of the invention, the wake-up command packet issued by the base station specifically includes:

[0066] When the base station needs to initiate image scanning, it determines the target tag ID to be the electronic paper tag ID that needs to be woken up, and determines the target listening level to be the level that the electronic paper tag that does not need to be woken up needs to switch to.

[0067] Generate a wake-up command packet based on the target tag ID and the target monitoring level;

[0068] The wake-up command packet is broadcast to electronic paper tags within a preset coverage area.

[0069] In an embodiment of the present invention, see Figure 4This is a schematic diagram of a wake-up command packet provided by the present invention. The wake-up command packet includes an identification code, a command, a random code, a level, and a target ID. When a base station needs to initiate map scanning, it sends a wake-up command packet and broadcasts it to the electronic paper tags so that all electronic paper tags within the coverage area can receive the wake-up command packet. In the wake-up command packet, the target ID is the tag that needs to be woken up, and the level is the level that tags that do not need to be woken up need to switch to.

[0070] Step 103: Determine whether the target tag ID parsed from the wake-up command packet is the same as the ID of the electronic paper tag.

[0071] Step 104: If the target tag ID is the same as the electronic paper tag ID, then wake up the electronic paper tag and initiate a connection.

[0072] Step 105: If the target tag ID is different from the electronic paper tag ID, then switch the monitoring level of the electronic paper tag to the target monitoring level.

[0073] Furthermore, in this embodiment of the invention, switching the monitoring level of the electronic paper tag to the target monitoring level specifically involves:

[0074] When the target monitoring level is the first monitoring level, the monitoring level of the electronic paper tag is switched to the first monitoring level, and the working state of the electronic paper tag is switched to the ready monitoring state.

[0075] In this embodiment of the invention, when an electronic paper tag receives a wake-up command packet from a base station and parses out the target tag ID and the target listening level, each electronic paper tag compares its own ID with the target tag ID. If they are the same, it quickly wakes up and initiates a connection; if they are different, it switches its own listening level to the target listening level in the wake-up command packet so that it can be quickly woken up the next time it wakes up.

[0076] In this embodiment of the invention, since the actual refresh frequency of the electronic paper tag is not very high, the refresh frequency is generally 5 times a day, each time for 10 seconds, which only accounts for 50 / 86400 of a day, the electronic paper tag monitoring method provided by this invention can make the electronic paper tag in the monitoring state most of the time, thereby minimizing power consumption and enabling quick wake-up when needed.

[0077] The electronic paper tag monitoring method provided in this invention has the following advantages compared with the prior art:

[0078] This invention controls the electronic paper tag to an idle listening state. Only upon receiving a wake-up command packet from a base station, it compares the target tag ID in the wake-up command packet with its own ID. If they match, it quickly wakes itself up and establishes a connection with the base station. If they do not match, it switches its listening level to the target listening level in the wake-up command packet to facilitate rapid wake-up the next time it needs to be woken up. This invention maintains minimal power consumption during idle periods and wakes up and connects to the electronic paper tag as quickly as possible when the base station initiates a connection.
