[0055] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] It should be noted that, in the embodiments of the present application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0057] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second", etc. are not limiting the quantity and execution order.

[0058] The Internet of Things (IoT) is a network based on information carriers such as the Internet or traditional telecommunications networks that allows all independently addressable objects to be interconnected. With the rapid development of the IoT, it is expected to promote the intelligent interconnection of billions or even tens of billions of objects.

[0059] The Internet of Things is usually composed of active IoT devices. Active IoT devices refer to IoT devices that rely on power (such as AC or battery) to achieve data transmission, processing or control. Many active IoT devices in the Internet of Things are difficult to power because they are widely distributed, need to be flexible and mobile, or are used in extreme environments.

[0060] Passive IoT technology solves this problem. Passive IoT can be composed of passive IoT devices. Passive IoT devices do not need built-in batteries or are connected to the mains. They can function by collecting environmental energy, so they have a long service life, are more compact, simplify maintenance, and improve safety and efficiency. As the demand for IoT continues to grow, passive IoT technology is expected to support a larger scale of terminal node devices and achieve larger-scale sensing perception and transmission connections.

[0061] For example, the related technology proposes a solution of using macro base stations or micro base stations in the 5G communication network to remotely drive passive IoT devices through radio frequency signals.

[0062] For example, Figure 1 The following is a schematic diagram of the composition of the 5G passive sensor Internet of Things system. Figure 1 As shown, the Internet of Things system includes: a cloud processing layer, a communication layer, a passive sensing layer, and an application layer.

[0063] Among them, the perception layer can rely on various microwave direct drive frequency conversion (MDFC) sensors to collect environmental information such as tags, temperature, vibration, and humidity.

[0064] The communication layer can rely on macro base stations or micro base stations to drive the sensors of the perception layer and transmit the information from the perception layer to the cloud processing layer.

[0065] The cloud processing layer can perform data mining, machine learning, edge computing, hazard warning, real-time monitoring, and automatic control.

[0066] The application layer can involve various vertical industry scenarios such as chemical industry, electricity, brewing, gas, mining companies, and industry.

[0067] However, using macro base stations or micro base stations to drive passive IoT devices is prone to various problems, such as passive IoT devices failing to work properly or frequently disconnecting, communication delays, etc.

[0068] Based on this, the embodiments of the present application provide a passive Internet of Things device driving method, a communication device and a program product, which can add a relay device between the base station and the passive Internet of Things device, and drive the passive Internet of Things device in a third-party relay manner, thereby solving the problems of passive Internet of Things devices not being able to work normally or frequently disconnecting, communication delays, etc.

[0069] The following is an introduction with reference to the accompanying drawings.

[0070] Figure 2 A schematic diagram of the composition of a relay system provided in an embodiment of the present application. Figure 2As shown, the relay system may include multiple relay devices ( Figure 2 In the figure, two relay devices, relay device 100 and relay device 200, are used as examples. Each relay device can drive one or more passive IoT devices ( Figure 2 In the figure, the relay device 100 corresponds to driving the passive Internet of Things device 300, and the relay device 200 corresponds to driving the passive Internet of Things device 400 is taken as an example).

[0071] Among them, the relay device of the relay system can be a mobile relay terminal, or it can also be a fixed radio frequency base station. The embodiment of the present application does not limit the specific form of the relay device. The passive Internet of Things device can be an Internet of Things device such as a passive electronic tag (such as a passive radio frequency identification (RFID) tag) or a passive sensor. The embodiment of the present application does not limit the specific form of the passive Internet of Things device.

[0072] For example, taking the relay device 100 driving the passive IoT device 300 as an example, the outdoor macro station 500 can send a driving instruction to the relay device 100 through a radio frequency signal (such as a 5G air interface signal), and the driving instruction can be used to instruct the passive IoT device 300 to drive. The relay device 100 can respond to the driving instruction and send a driving signal to the passive IoT device 300. The passive IoT device 300 can use the MDFC technology to convert the driving signal into usable electrical energy, and use this electrical energy to send an uplink signal to the relay device 100.

[0073] The outdoor macro station 500 may be a base station (BS), a base transceiver station (BTS), a 3G base station (NodeB), a 4G base station (evolved NodeB, eNB), or a 5G base station (next generation NodeB, gNB), etc. The embodiment of the present application does not limit the specific type of the outdoor macro station 500.

[0074] In some embodiments, the relay device can be set within a preset range of the passive Internet of Things device.

[0075] The preset range may be less than or equal to the coverage range of the relay device. For example, the preset range may be a radius of 10 meters, a radius of 20 meters, a radius of 50 meters, or a radius of 100 meters, etc. The embodiment of the present application does not limit the specific value of the preset range.

[0076] In some embodiments, the relay device may be located between the base station and the corresponding passive IoT device. In other words, the relay device and the base station are located on the same side of the corresponding passive IoT device, and the distance between the relay device and the corresponding passive IoT device may be smaller than the distance between the passive IoT device and the outdoor macro station 500.

[0077] For example, the distance between the relay apparatus 100 and the passive IoT device 300 may be smaller than the distance between the outdoor macro station 500 and the passive IoT device 300 .

[0078] For another example, the distance between the relay device 200 and the passive IoT device 400 may be smaller than the distance between the outdoor macro station 500 and the passive IoT device 400 .

[0079] Above Figure 2 The relay system provided in the embodiment of the present application is introduced by taking the relay device directly communicating with the base station as an example. Optionally, the base station can also communicate with other distributed relay devices through a main relay device. Figure 3 A schematic diagram of another relay system provided in an embodiment of the present application. Figure 3 As shown in the above Figure 2 Based on the components of the relay system shown, the relay system may include: a main relay device 600. The above relay devices 100 and 200 may be understood as multiple distributed relay devices. The main relay device 600 has a communication connection with multiple distributed relay devices, and the main relay device 600 has a communication connection with the outdoor macro station 500.

[0080] The main relay device 600 may be used to mutually transmit signals between the outdoor macro station 500 and the distributed relay devices.

[0081] For example, taking the above-mentioned relay device 100 driving the passive IoT device 300 as an example, the outdoor macro station 500 can send a driving instruction to the main relay device 600 through a radio frequency signal (such as a 5G air interface signal), and the driving instruction can be used to instruct the driving of the passive IoT device 300. The main relay device 600 can forward the driving instruction to the relay device 100. The relay device 100 can respond to the driving instruction and send a driving signal to the passive IoT device 300. The passive IoT device 300 can use MDFC technology to convert the driving signal into usable electrical energy, and use this electrical energy to send an uplink signal to the relay device 100. The relay device 100 can forward the uplink signal to the main relay device 600. The main relay device 600 can generate an uplink radio frequency signal based on the uplink signal and send it to the outdoor macro station 500.

[0082] In some embodiments, the main relay device 600 and the distributed relay devices may use relay signals to transmit driving instructions and uplink signals.

[0083] For example, the main relay device 600 may send a downlink relay signal to the distributed relay device, wherein the downlink relay signal includes a driving instruction. The distributed relay device may send an uplink relay signal to the main relay device, wherein the uplink relay signal includes an uplink signal.

[0084] Optionally, the main relay device 600 may be connected to the distributed relay devices by wire. In this case, the relay signal may be understood as a baseband signal.

[0085] Optionally, the main relay device 600 may be wirelessly connected to the distributed relay devices. In this case, the relay signal may be understood as a radio frequency signal.

[0086] The following is an introduction to the passive IoT device driving method provided in the embodiment of the present application.

[0087] The embodiment of the present application first provides a passive Internet of Things device driving method, which can be applied to a relay device (such as the above-mentioned relay device 100 or relay device 200, which can be referred to as a first relay device for the sake of distinction). Figure 4 A schematic diagram of a passive IoT device driving method provided in an embodiment of the present application. Figure 4 As shown, the method includes the following steps:

[0088] S101: A first relay device obtains a driving instruction from a base station.

[0089] The driving instruction is used to instruct driving the first passive IoT device. The base station can also be understood as the outdoor macro station 500 described above.

[0090] S102: The first relay device sends a driving signal to the first passive Internet of Things device in response to the driving instruction.

[0091] The driving signal may be sent in the form of a radio frequency signal, and may also be understood as a radio frequency driving signal.

[0092] S103. The first relay device receives an uplink signal sent from the first passive Internet of Things device.

[0093] For example, the receiving module inside the first passive Internet of Things device can capture the driving signal from the first relay device and convert it into usable electrical energy, which can be used to drive the first passive Internet of Things device to perform subsequent data collection, generate an uplink signal based on the collected data, and send an uplink signal to the first relay device, etc.

[0094] As an example, the passive Internet of Things device driving method provided in the embodiment of the present application can be applied in warehousing and logistics scenarios.

[0095] For example, taking the first passive Internet of Things device as a passive electronic tag, the passive electronic tag can be set on the goods in the logistics warehouse. The first relay device can send a driving signal to the passive electronic tag. When the driving signal is received, the passive electronic tag can use the MDFC technology to convert the driving signal into usable electrical energy, and use this electrical energy to send an uplink signal to the first relay device. In this way, when the goods are not shipped out of the warehouse, the passive electronic tag on the goods can receive the driving signal and send an uplink signal to the first relay device. The uplink signal can be understood as the item information used to represent the item where the passive electronic tag is located. When the goods are shipped out of the warehouse, the electronic tag on the goods cannot send an uplink signal to the first relay device. According to the uplink signal obtained by the first relay device, the current inventory in the logistics warehouse can be determined.

[0096] As another example, the passive Internet of Things device driving method provided in the embodiment of the present application can also be applied in the winemaking field.

[0097] For example, taking the first passive IoT device as a passive sensor, the passive sensor can be set in a brewery. The first relay device can send a driving signal to the passive sensor. When receiving the driving signal, the passive sensor can use the MDFC technology to convert the driving signal into usable electrical energy, and use the electrical energy to collect data such as temperature and humidity in the brewery, convert the data into an uplink signal and send it to the first relay device. In this way, the staff can remotely monitor the temperature and humidity of the brewery.

[0098] It should be noted that the above two specific application scenarios are only examples, and the passive IoT device driving method provided in the embodiment of the present application can be applied to the above chemical, electric power, brewing, gas, mining enterprises, and industrial scenarios that require the collection and analysis of sensor signals from sensors. The embodiment of the present application does not limit this.

[0099] It should be understood that when the relevant technology uses macro base stations or micro base stations in the communication network to remotely drive passive IoT devices through radio frequency signals, the signal strength level may not meet the requirements due to building obstruction and signal attenuation, resulting in the inability to drive the passive IoT devices normally, causing the passive IoT to fail to work properly, frequently disconnect, or have communication delays, etc.

[0100] In the passive IoT device driving method provided in the embodiment of the present application, the first relay device can obtain the driving instruction from the base station, and in response to the driving instruction, send a driving signal to the first passive IoT device, and then receive the uplink signal sent by the first passive IoT device. The first relay device can expand the coverage of the base station to meet the coverage requirements of the passive IoT device, and the driving signal power of the passive IoT device is stronger and more stable, which can provide better communication quality and avoid frequent disconnection and communication delay of the passive IoT.

[0101] The above-mentioned S101 is introduced below.

[0102] In some possible embodiments, as described above Figure 2 As shown in , the first relay device (relay device 100 or relay device 200) can communicate directly with the base station (outdoor macro station 500). In this case, the above S101 can specifically include the following steps:

[0103] Step 1a: The first relay device receives a downlink radio frequency signal from a base station.

[0104] The downlink radio frequency signal includes a driving instruction.

[0105] In some other possible embodiments, as described above Figure 3 As shown in , the first relay device (relay device 100 or relay device 200) can be any one of a plurality of distributed relay devices, and the first relay device can communicate with the base station (outdoor macro station 500) through the second relay device (main relay device 600). In this case, the above S101 can specifically include the following steps:

[0107] The downlink relay signal includes a driving instruction.

[0108] In a possible implementation, the downlink relay signal may be sent to the first relay device after the second relay device receives the driving instruction and determines that the distributed relay device corresponding to driving the first passive IoT device is the first relay device based on the correspondence between the first passive IoT device and the device. The specific process of the second relay device sending the downlink relay signal can be referred to the following method embodiment with the second relay device as the execution subject, which will not be repeated here.

[0109] The device correspondence relationship includes identifiers of multiple passive Internet of Things devices and identifiers of relay devices corresponding to driving each passive Internet of Things device, and the first passive Internet of Things device is any one of the multiple passive Internet of Things devices.

[0110] In another possible implementation,

[0111] The downlink relay signal is sent to the first relay device after the second relay device determines that the distributed relay device closest to the first passive Internet of Things device is the first relay device based on the device location information when the third relay device fails. The specific process can also be referred to the following method embodiment with the second relay device as the execution subject, and will not be repeated here. Among them, the third relay device is a distributed relay device corresponding to the first passive Internet of Things device determined by the second relay device based on the correspondence between the first passive Internet of Things device and the device; the device correspondence includes the identification of multiple passive Internet of Things devices, and the identification of the relay device corresponding to each passive Internet of Things device, and the first passive Internet of Things device is any one of the multiple passive Internet of Things devices; the device location information includes the respective positions of the multiple distributed relay devices and the respective positions of the multiple passive Internet of Things devices.

[0112] In some embodiments, as described above Figure 2 As shown in , the first relay device (relay device 100 or relay device 200) can communicate directly with the base station (outdoor macro station 500). In this case, after the above S103, the method may further include the following steps:

[0113] Step 1c: The first relay device generates an uplink radio frequency signal based on the uplink signal and sends the uplink radio frequency signal to the base station.

In this case, after the above S103, the method can also include the following steps:

[0115] Step 1d: The first relay device generates an uplink relay signal based on the uplink signal and sends it to the second relay device, so that the second relay device generates an uplink radio frequency signal based on the uplink relay signal and sends it to the base station.

[0116] It should be noted that the passive IoT device driving method provided in the embodiment of the present application is introduced by taking driving the first passive IoT device as an example, and other passive IoT devices such as the second passive IoT device can also be driven according to the passive IoT device driving method. The embodiment of the present application does not limit this.

[0117] The passive IoT device driving method provided by the embodiment of the present application is introduced above by taking the first relay device (relay device 100 or relay device 200) in the relay system as the execution subject as an example. Next, the embodiment of the present application provides another passive IoT device driving method, which can be applied to the second relay device (that is, the above-mentioned main relay device 600). Figure 5 A schematic diagram of another passive IoT device driving method provided in an embodiment of the present application. Figure 5 As shown, the method includes the following steps:

[0118] S201: The second relay device receives a driving instruction from a base station.

[0119] The driving instruction is used to instruct driving the first passive Internet of Things device.

[0120] For example, the second relay device may receive a downlink radio frequency signal from the base station, and the downlink radio frequency signal may include a driving instruction.

[0121] S202: The second relay device generates a downlink relay signal in response to the driving instruction.

[0122] The downlink relay signal includes a driving instruction.

[0123] S203. The second relay device sends a downlink relay signal to the first relay device, so that the first relay device sends a driving signal to the first passive Internet of Things device in response to the driving instruction and receives an uplink signal sent from the first passive Internet of Things device.

[0124] The first relay device is any one of a plurality of distributed relay devices.

[0125] In some possible embodiments, before the above S203, the method may further include the following steps:

[0126] Step 1e: The second relay device determines, based on the corresponding relationship between the first passive IoT device and the device, that the distributed relay device corresponding to driving the first passive IoT device is the first relay device.

[0127] Among them, the device correspondence relationship includes multiple passive Internet of Things devices and a relay device corresponding to driving each passive Internet of Things device, and the first passive Internet of Things device is any one of the multiple passive Internet of Things devices.

[0128] Exemplarily, the device correspondence relationship may be specifically as shown in the following Table 1:

[0129] Table 1

[0130] Identification of Passive IoT Devices Relay device identification Passive IoT Devices1 Relay device 1 Passive IoT Devices 2 Relay device 2 Passive IoT Devices 3 Relay device 3

[0131] As shown in Table 1, the table may include identification items of passive IoT devices and identification items of relay devices. Among them, the identification items of passive IoT devices may include: passive IoT device 1, passive IoT device 2, and passive IoT device 3. The identification items of relay devices may include: relay device 1, relay device 2, and relay device 3. There is a corresponding relationship between passive IoT device 1 and relay device 1, there is a corresponding relationship between passive IoT device 2 and relay device 2, and there is a corresponding relationship between passive IoT device 3 and relay device 3.

[0132] Optionally, the second relay device may use the identifier of the first passive Internet of Things device as an index, traverse the search device correspondence, determine the target identifier of the relay device corresponding to the identifier of the first passive Internet of Things device in the device correspondence, and use the relay equipment corresponding to the target identifier as the relay device corresponding to driving the first passive Internet of Things device.

[0133] The passive IoT device driving method provided in the embodiment of the present application can also add a second relay device between the base station and the first relay device as a main relay device, so as to distribute the driving instructions for driving different passive IoT devices to the corresponding driven relay devices. While further expanding the coverage of the base station, the computing requirements of the base station for distributing the driving instructions are shared, which can reduce the requirements for the computing resources of the base station.

[0134] In some other possible embodiments, before the above S203, the method may further include the following steps:

[0135] Step 1f: The second relay device determines that the distributed relay device corresponding to driving the first passive Internet of Things device is the third relay device based on the corresponding relationship between the first passive Internet of Things device and the device.

[0136] Among them, the third passive Internet of Things device is any one of the multiple passive Internet of Things devices, and the third passive Internet of Things device is different from the first Internet of Things device.

[0137] The details of step 1f may refer to the above step 1e, which will not be repeated here.

[0138] Step 2f: When the third relay device fails, the second relay device determines that the distributed relay device closest to the first passive Internet of Things device is the first relay device based on the device location information.

[0139] Among them, the device location information includes the respective locations of multiple distributed relay devices and the respective locations of multiple passive Internet of Things devices.

[0140] For example, the second relay device can calculate the distance between the first passive IoT device and the multiple distributed relay devices based on the location of the first passive IoT device and the respective locations of the multiple distributed relay devices, and then select the relay device with the shortest distance as the corresponding relay device for driving the first passive IoT device.

[0141] Optionally, before step 2f above, the second relay device may also receive heartbeat packets periodically sent by each distributed relay device. If the second relay device does not receive a heartbeat packet from a distributed relay device for more than a preset time, the second relay device may determine that the distributed relay device is faulty.

[0142] The preset duration may be preset in the second relay device. For example, the preset duration may be set to 1 minute, 3 minutes, 5 minutes, or 10 minutes, etc. The embodiment of the present application does not limit the specific duration of the preset duration.

[0143] The passive Internet of Things device driving method provided in the embodiment of the present application can also drive the first passive Internet of Things device through the first relay device closest to the first passive Internet of Things device when the third relay device corresponding to driving the first passive Internet of Things device fails. In this way, when there is a faulty relay device in the relay system, other relay devices can replace the faulty relay device to drive the passive Internet of Things device, thereby improving the reliability of the solution for driving the passive Internet of Things device.

[0144] In some embodiments, after the above S203, the method may further include the following steps:

[0145] Step 1g: The second relay device receives the uplink relay signal from the first relay device.

[0146] The uplink relay signal is determined by the first relay device based on the uplink signal.

[0147] Step 2g: The second relay device generates an uplink radio frequency signal based on the uplink relay signal and sends it to the base station.
