It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0048] At present, due to frequent network interactions and communication protocol problems, the electronic tags used in cold chain transportation consume a lot of power, which affects the endurance of the electronic tags during long-term transportation. Among them, related technologies reduce the number of communications by reducing the acquisition frequency of sensors, but this method is difficult to flexibly respond to complex and changing transportation environments and the needs of different transportation environments. In addition, the communication protocol used fails to transmit data efficiently, and the communication overhead is large for interactive scenarios with small data volumes; the communication frequency of the electronic tags is single, and power consumption management is insufficient.

[0049] In response to the above problems, an embodiment of the present application provides a communication method for an electronic tag, which can dynamically adjust the communication frequency with the cloud platform in combination with the status data collected by the sensor, thereby significantly reducing the power consumption of the electronic tag during cold chain transportation and improving the battery life of the electronic tag.

[0050] The architecture of the electronic tag communication system is introduced below through embodiments.

[0051] See also Figure 1 , Figure 1 This is a schematic diagram of the architecture of the electronic tag communication system provided in the embodiment of the present application. Figure 1 As shown, the system includes an electronic tag 10 and a cloud platform 20. The electronic tag 10 includes a processor 101, a positioning sensor 102, a mobile communication module 103, a temperature sensor 104, a humidity sensor 105, and a display screen 106. The cloud platform 20 includes a Constrained Application Protocol (CoAP) communication module 201, as well as basic services, other platform services and other modules.

[0052] Exemplarily, the mobile communication module 103 of the electronic tag 10 communicates with the CoAP communication module 201 of the cloud platform 20 based on the CoAP protocol; the CoAP protocol is suitable for the transmission of small data packets, thereby reducing the power consumption generated during the communication process.

[0053] The mobile communication module 103 may be a 4G module or a cellular module, which implements low-power network interaction based on a 4G CAT1 network, thereby reducing power consumption of the electronic tag 10 during communication.

[0054] Exemplarily, the positioning sensor 102 is used to collect the location information of the electronic tag 10; the temperature sensor 104 is used to collect the temperature information of the environment in which the electronic tag 10 is located, and the humidity sensor 105 is used to collect the humidity information of the environment in which the electronic tag 10 is located; the processor 101 is used to obtain the status information of the electronic tag 10, such as the location information, temperature information and humidity information, and dynamically adjust the communication frequency with the cloud platform 20 based on the status information; when the status information does not change or the change is small, the communication frequency is reduced and unnecessary network interactions are reduced, thereby reducing the power consumption of the electronic tag 10 and extending the service life of the electronic tag 10.

[0055] The specific implementation process of the electronic tag communication method is introduced below through an embodiment.

[0056] See also Figure 2 , Figure 2 The following is a schematic diagram of the implementation flow of the communication method of the electronic tag provided in the embodiment of the present application. Figure 2The subject of the execution of this method may be Figure 1 The electronic tag 10 shown in FIG. 1 includes a positioning sensor 102. The method may include the following steps:

[0057] S201, obtaining position information collected by a positioning sensor based on a first collection period.

[0058] In the embodiment of the present application, the positioning sensor of the electronic tag can be a global positioning system (GPS) sensor. The first acquisition period can be a short time, such as 1 second or 1 minute, or a few minutes or several hours, which can be configured based on the application scenario. For example, in the transportation process of cold chain logistics, valuables, etc., the positioning sensor can be set to collect location information in real time, such as once per second.

[0059] For example, the collected location information may include geographic location data such as longitude, latitude, altitude, and metadata such as collection time. The electronic tag may send the collected location information to a cloud platform for subsequent monitoring, tracking, analysis, and processing.

[0060] S202, when the change rate of the location information is less than the location change frequency threshold, the communication cycle with the cloud platform is adjusted from the first communication cycle to the second communication cycle; wherein the first communication cycle is greater than or equal to the first collection cycle, and the second communication cycle is greater than the first communication cycle.

[0061] In the embodiment of the present application, the electronic tag compares the position information collected twice adjacent to each other based on the position information collected by the positioning sensor to determine whether the position information has changed and the rate of change of the change.

[0062] Normally, the positioning sensor of the electronic tag collects location information once and sends it to the cloud platform once, that is, the communication cycle with the cloud platform can be the first collection cycle (in this case, the first communication cycle is the same as the first collection cycle); in scenarios where the location information has not changed, such as when stopping for a rest during transportation, continuously sending location information to the cloud platform consumes more power.

[0063] This application adjusts the communication frequency or communication cycle with the cloud platform based on the judgment of the location information. For example, the collection cycle of the positioning sensor is once every 5 minutes, and the location change frequency threshold can be 1 time / 5 minutes. If the location information collected twice is the same, it means that the location information has not changed, and the change rate of the location information is 0. At this time, the location information can be reported based on the first collection cycle of the positioning sensor, and the location information can continue to be collected at the next collection time, and compared with the location information collected last time, and the communication cycle with the cloud platform can be dynamically adjusted based on the comparison result.

[0064] Among them, the location change frequency threshold can be configured based on different application scenarios. For example, it can be set in combination with the change range. When the distance change is less than the set first distance threshold (such as the distance difference between the location information collected twice is small), even if the location information collected twice is different, it is possible to temporarily not report it and store the collected location information. When the distance from the location information collected at the time of non-reporting reaches the set second distance threshold, the reporting of the location information can be triggered once, and the stored unreported location information can be sent to the cloud platform at the same time, thereby realizing dynamic adjustment of the communication cycle and reducing power consumption caused by frequent interactions.

[0065] It should be noted that the first communication cycle can be the same as the first acquisition cycle, or can be longer than the first acquisition cycle; for example, if the first acquisition cycle is 5 minutes and the collected location information keeps changing, the first communication cycle can also be set to 30 minutes (at this time, the time interval of the first communication cycle is longer than the time interval of the first acquisition cycle); the second communication cycle can be any time interval longer than the first communication cycle when the location information remains unchanged or changes slightly, and can be dynamically adjusted or set based on the change of the location information. The various thresholds, the first acquisition cycle, the first communication cycle, and the second communication cycle that supports dynamic adjustment set in the electronic tag can be configured by receiving the configuration information sent by the cloud platform, and can also be set by receiving the configuration instructions input by the user. The communication frequency is adjusted from the first communication cycle to the second communication cycle with a longer time interval to reduce unnecessary communications and save power.

[0066] S203: Send status information to the cloud platform according to the second communication cycle.

[0067] In the embodiment of the present application, the status information may include location information, environmental information, and device information. When the location information has not changed and the environmental information is within a preset range of change, the electronic tag extends the communication cycle from the first communication cycle to the second communication cycle, reduces the communication frequency with the cloud platform, extends the communication time interval, thereby reducing unnecessary communication, and sends a small data packet corresponding to the status information to the cloud platform, thereby reducing the power consumption generated during the communication process.

[0068] The environmental information may include temperature and humidity information of the transportation environment, and the device information may include battery power, Mac address, device model and other information.

[0069] like Figure 3As shown, the time interval of the first collection cycle is less than the time interval of the second communication cycle. For example, if the location information does not change from the 1st collection point to the 6th collection point in the first collection cycle, the electronic tag can adjust the communication cycle from the first communication cycle to the second communication cycle; if the location information does not change at all, a value of location information can be reported for multiple collection moments. If the location information changes within the preset distance range, that is, the change is very small, then based on the adjusted second communication cycle, multiple location information is reported at one time, that is, a value of location information is reported for each collection moment. The specific reporting form can be set based on the actual application scenario and the change of location information.

[0070] For example, if the location information detected by the positioning sensor remains unchanged, the time interval of the second communication cycle can be further extended. The time interval of the second communication cycle can be dynamically adjusted based on the actual changes in the location information, and can also be configured based on the configuration information issued by the cloud platform; for example, if the location information continuously collected based on the first sampling period has not changed within 12 hours, the time interval is adjusted to more than 1 day; or when the collected location information changes, a report is triggered to extend the reporting time interval and reduce unnecessary communication power consumption.

[0071] In some embodiments, the electronic tag includes a mobile communication module, and according to the second communication cycle, sends status information to the cloud platform, including:

[0072] According to the second communication cycle, the status information is sent to the cloud platform through the mobile communication module based on the restricted application protocol.

[0073] Exemplarily, the mobile communication module can be a cellular module or a 4G module; the electronic tag accesses the network through the mobile communication module, and sends status information to the cloud platform based on the first application protocol CoAP, especially for the sending of the above-mentioned small data packets, which can reduce the power consumption generated during the communication process.

[0074] Among them, the electronic tag can use 4G CAT1 mode to transmit data, with low power consumption, and can interact with the cloud platform without going through a gateway (such as a Bluetooth gateway).

[0075] Correspondingly, the CoAP communication module of the cloud platform can send configuration information and image information to the electronic tag through the CoAP communication queue; wherein the configuration information is used to configure the various thresholds, acquisition cycles, and communication cycles that need to be dynamically adjusted in the electronic tag. The cloud platform packages the image information into device instructions and puts them into the CoAP communication queue of the CoAP communication module; after the electronic tag activates the heartbeat, it establishes a communication connection with the cloud platform, obtains the image information to be displayed from the cloud platform, and after obtaining the image information, displays the image on the display screen in the form of a base map.

[0076] In some embodiments, the electronic tag further includes a temperature sensor and a humidity sensor; the method further includes:

[0077] Based on the second collection cycle, temperature information and humidity information are collected respectively by the temperature sensor and the humidity sensor; according to the second communication cycle, status information is sent to the cloud platform, including: when the temperature change value of the temperature information is within the first temperature change threshold range, and the humidity change value of the humidity information is within the first humidity change threshold range, according to the second communication cycle, the location information and all the temperature information and humidity information to be reported in the second communication cycle are sent to the cloud platform; wherein the second collection cycle is less than the second communication cycle; the status information includes temperature information, humidity information and location information.

[0078] Exemplarily, during the transportation process, the electronic tag periodically collects temperature information and humidity information through the temperature sensor and the humidity sensor respectively, and transmits the temperature information and humidity information to the processor, which determines the changes in temperature and humidity; when the temperature change value corresponding to the temperature information and the humidity change value corresponding to the humidity information are both within the preset threshold range, that is, the temperature and humidity changes are small, it is not necessary to report the temperature information and humidity information collected in each second collection period, and the temperature information and humidity information collected based on the second collection period can be saved; thereby, when sending status information to the cloud platform based on the first communication period or the second communication period with an extended time interval, all temperature information and all humidity information collected within the communication period are sent.

[0079] like Figure 3 As shown, the temperature sensor and humidity sensor (collectively referred to as temperature and humidity sensors) collect temperature information and humidity information based on the second collection period; the communication period with the cloud platform is the first communication period or the second communication period after the extended time interval. For example, when reporting based on the second communication period, when sending status information to the cloud platform at reporting time point 2, the temperature information and humidity information collected at time points 1 to 5 corresponding to the second collection period are reported together; accordingly, when sending status information to the cloud platform at reporting time point 3, the temperature information and humidity information collected at time points 6 to 10 corresponding to the second collection period are reported together, thereby maintaining data continuity. At the same time, if the location information does not change or changes slightly, the reporting form of the location information is determined based on its change.

[0080] In some embodiments, the method further comprises:

[0081] When the temperature change value is greater than the first temperature change threshold, or the humidity change value is greater than the first humidity change threshold, the collected temperature information, humidity information and location information are sent to the cloud platform according to the second collection cycle.

[0082] For example, when the temperature information changes greatly or the humidity information changes greatly, the temperature information and humidity information are sent to the cloud platform based on the collection time point to notify the cloud platform that the temperature information and humidity information in the transportation environment have changed greatly and corresponding processing operations need to be taken. For example, the first temperature change threshold can be set to +10 degrees and -10 degrees, and the first humidity threshold can be set to +15% and -15%.

[0083] It should be noted that when the location information has not changed and the changes in temperature information and humidity information exceed their corresponding thresholds, the status information will no longer be reported according to the adjusted second communication cycle. The communication cycle can be adjusted based on the changes in temperature information and humidity information, and when reporting, all stored status information to be reported can be reported together to maintain the continuity of each information.

[0084] In some embodiments, the electronic tag further includes an alarm; the method further includes:

[0085] When the temperature change value is greater than the first temperature change threshold, or the humidity change value is greater than the first humidity change threshold, an alarm message is issued through the alarm.

[0086] Exemplarily, when the temperature information and humidity information change greatly, the electronic tag sends an alarm message through an alarm; for example, an alarm sound is emitted through a buzzer or the changes in temperature and humidity are announced through voice, or a flashing signal is emitted through an LED, etc. to give an alarm.

[0087] In some embodiments, the method further comprises:

[0088] When the change rate of the location information is greater than or equal to the location change frequency threshold, the location information and all the temperature information and humidity information to be reported are sent to the cloud platform according to the first communication cycle.

[0089] Exemplarily, when the detected location information continues to change, the collected location information, temperature information and humidity information are reported based on the set first communication cycle. The first communication cycle may be greater than the first collection cycle; for example, the first collection cycle is 5 minutes, and the first communication cycle may be 30 minutes.

[0090] In some embodiments, the electronic tag further includes a display screen; the method further includes:

[0091] When the temperature change value is greater than the second temperature change threshold, the temperature information displayed on the display screen is updated; or when the humidity change value is greater than the second humidity change threshold, the humidity information displayed on the display screen is updated; wherein the second temperature change threshold is less than the first temperature change threshold, and the second humidity change threshold is less than the first humidity change threshold.

[0092] For example, when the temperature information or humidity information changes slightly, continuously updating the display on the display screen also consumes more power; the embodiment of the present application determines the timing of updating the display screen by judging the temperature change value and the humidity change value. By setting the second temperature change threshold and the second humidity change threshold, for example, setting the second temperature change threshold to 1 degree and the second humidity change threshold to 5%, when the change value exceeds the change threshold, the temperature information and humidity information displayed on the display screen are updated; and the electronic tag stores each collected temperature data in the flash memory.

[0093] The display screen may be an electronic ink screen, and may dynamically display temperature information and humidity information.

[0094] In some embodiments, the electronic tag further includes a Bluetooth module; the method further includes:

[0095] Through the Bluetooth module, it accesses the cellular gateway based on the Bluetooth protocol and communicates with the cloud platform based on the cellular gateway.

[0096] For example, when there are multiple electronic tags in the current transportation environment, it is also possible to connect to the same cellular gateway through the Bluetooth protocol based on the Bluetooth module integrated in the electronic tag, access the cloud platform based on the cellular gateway, and communicate with the cloud platform, thereby saving communication costs and further reducing the power consumption of the electronic tag.

[0097] Through the embodiments of the present application, the electronic tag communicates with the cloud platform with low power consumption based on the CoAP protocol, reducing the communication overhead between the electronic tag and the cloud platform, and is suitable for low-power consumption scenarios with small data volumes; and based on the information collected by the positioning sensor, temperature sensor, and humidity sensor, dynamically adjusts the communication frequency with the cloud platform, greatly reducing the device power consumption of the electronic tag; realizes the intelligent management of electronic tags during cold chain transportation, and significantly extends the use time of the electronic tags while ensuring the accuracy of the monitoring data, and is suitable for long-term and long-distance transportation scenarios.

[0098] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
