[0002] 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.

[0003] Passive IoT technology solves this problem. For example, related technologies have proposed a solution to remotely drive passive IoT devices using macro or micro base stations in a communication network through radio frequency signals.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] The cloud processing layer can perform data mining, machine learning, edge computing, hazard warning, real-time monitoring, and automatic control.

[0060] The application layer can involve various vertical industry scenarios such as chemical industry, electricity, brewing, gas, mining companies, and industry.

[0061] 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.

[0062] Based on this, the embodiments of the present application provide a passive IoT device driving method, a communication device and an indoor distributed system, which can utilize the remote unit in the indoor distributed system to directly drive the passive IoT device through a radio frequency signal, thereby solving the problems of passive IoT devices not being able to work properly or frequently disconnecting, communication delays, etc.

[0063] The following is an introduction with reference to the accompanying drawings.

[0064] Figure 2 The schematic diagram of the composition of the room distribution system provided in the embodiment of the present application. Figure 2As shown, the indoor distribution system may include a base band unit (BBU) 100, a remote radio unit hub (RHUB) 200, and a pico remote radio unit (PRRU) 300. The BBU 100 and the RHUB 200 may be connected by wire. For example, the BBU 100 and the RHUB 200 may be connected by wire through a cross-floor optical fiber. The RHUB 200 and the PRRU 300 may be connected by wire. For example, the RHUB 200 and the PRRU 300 may be connected by wire through an optical-electrical hybrid cable.

[0065] Taking the example that the indoor distributed system is set in a building with three floors, the building can be equipped with a BBU, that is, the BBU 100 can include a BBU. Each floor can be equipped with a RHUB, that is, the RHUB 200 can include three RHUBs. Each floor can be equipped with multiple PRRUs, that is, the PRRU 300 can include multiple PRRUs ( Figure 2 In the example, two PRRUs are arranged on each floor, and a total of six PRRUs are arranged on three floors.) As an example, the BBU 100 may be arranged in a weak current room of the building.

[0066] The BBU 100 may be used to obtain a downlink baseband signal and transmit the downlink baseband signal to the PRRU 300 via the RHUB 200 .

[0067] Among them, the downlink baseband signal may include driving instructions for passive IoT devices.

[0068] For example, taking the user equipment remotely controlling the passive IoT device as an example, the user equipment can send a radio frequency signal including a driving instruction to a macro base station or a micro base station, and the macro base station or the micro base station can receive the radio frequency signal from the user equipment and convert the radio frequency signal into a (downlink) baseband signal. The macro base station or the micro base station can transmit the (downlink) baseband signal to the BBU 100 via an optical fiber.

[0069] The PRRU 300 may be configured to send a driving signal to the passive IoT device in response to a driving instruction in a downlink baseband signal, receive an uplink signal sent from the passive IoT device, and generate an uplink baseband signal based on the uplink signal (via the RHUB 200) and send the signal to the BBU 100.

[0070] The passive IoT device may be a passive electronic tag (such as a passive radio frequency identification (RFID) tag) or a passive sensor or other IoT device. The embodiment of the present application does not limit the specific form of the passive IoT device.

[0071] The following is an introduction to the passive IoT device driving method provided in the embodiment of the present application.

[0072] The embodiment of the present application first provides a passive Internet of Things device driving method, which can be applied to a remote unit in a room distribution system (such as the above-mentioned PRRU 300). Figure 3 A schematic diagram of a passive IoT device driving method provided in an embodiment of the present application. Figure 3 As shown, the method includes the following steps:

[0073] S101. The remote unit sends a driving signal to the passive IoT device.

[0074] 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.

[0075] S102. The remote unit receives an uplink signal sent from a passive IoT device.

[0076] For example, the receiving module inside the passive IoT device can capture the driving signal from the remote unit and convert it into usable electrical energy, which can be used to drive the passive IoT device for subsequent data collection, generate uplink signals based on the collected data, and send uplink signals to the remote unit.

[0077] 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.

[0078] For example, taking the 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 remote unit 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 remote unit. In this way, when the goods have not been shipped out of the warehouse, the passive electronic tag on the goods can receive the driving signal and send an uplink signal to the remote unit. The uplink signal can be understood as the cargo information used to represent the goods 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 remote unit. According to the uplink signal obtained by the remote unit, the current inventory in the logistics warehouse can be determined.

[0079] 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.

[0080] For example, if the passive IoT device is a passive sensor, the passive sensor can be set up in a brewery. The remote unit can send a driving signal to the passive sensor. When the driving signal is received, the passive sensor can use MDFC technology to convert the driving signal into usable electrical energy, and use this electrical energy to collect data such as temperature and humidity in the brewery, convert this data into an uplink signal and send it to the remote unit. In this way, the staff can remotely monitor the temperature and humidity of the brewery.

[0081] 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.

[0082] 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.

[0083] In the passive IoT device driving method provided in the embodiment of the present application, the remote unit in the indoor distributed system can send a driving signal to the passive IoT device and receive an uplink signal from the passive IoT device. Since the indoor distributed system is deployed indoors, there is no need to consider the impact of the building's exterior wall on the wireless signal, and the indoor distributed system is closer to the passive IoT device, with less signal attenuation. The indoor distributed system can 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 delays of the passive IoT.

[0084] In addition, the remote units and remote unit hubs in the indoor distributed system are usually connected by optical-electric hybrid cables, and the remote unit hubs and baseband units are usually connected by cross-floor optical fibers, which are relatively simple to construct and deploy. Later network optimization is more convenient, and the signal quality can be improved by adding indoor remote units in signal blind spots. In addition, the indoor distributed system can also provide better indoor positioning services.

[0085] The above-mentioned S101 is introduced below.

[0086] In some possible embodiments, a preset time interval is set in the remote unit. The above S101 may specifically include the following steps:

[0087] Step 1a: The remote unit periodically sends a driving signal to the passive IoT device at a preset time interval.

[0088] The preset time interval may be preset in the remote unit. For example, the preset time interval may be set to 1 second, 1 minute, 5 minutes, 10 minutes, 1 hour, 5 hours, 1 day, or 1 week, etc. The embodiment of the present application does not limit the specific value of the preset time interval.

[0089] In a possible implementation, the preset time interval may be manually set in the remote unit by a staff member.

[0090] For example, the staff can enter the setting interface of the remote unit according to the instructions provided by the remote unit manufacturer. The setting interface may include a setting item for the preset time interval. The staff can enter a specific duration in the setting item to set the preset time interval.

[0091] In another possible implementation, the preset time interval may also be determined according to the downlink baseband signal sent by the baseband unit. In this case, the above step 1a may specifically include the following steps:

[0092] Step 1.1a: The remote unit receives a downlink baseband signal from the baseband unit.

[0093] The downlink baseband signal may include a driving instruction for a passive IoT device and a preset time interval.

[0094] The specific process of generating the downlink baseband signal in step 1.1a can refer to the above Figure 2 It has been described in detail and will not be repeated here.

[0095] Step 1.2a: In response to the driving instruction, the remote unit periodically sends a driving signal to the passive IoT device at a preset time interval.

[0096] In some other possible embodiments, the driving signal sent each time may also be sent by the baseband unit to instruct the remote unit. In this case, the above S101 may specifically include the following steps:

[0097] Step 1b: The remote unit receives a downlink baseband signal from the baseband unit.

[0098] Among them, the downlink baseband signal includes driving instructions for passive IoT devices.

[0099] Step 2b: The remote unit sends a driving signal to the passive IoT device in response to the driving instruction.

[0100] In some embodiments, after receiving the uplink signal, the remote unit may further generate an uplink baseband signal based on the uplink signal and send the signal to the baseband unit.

[0101] In some embodiments, as described above, the passive IoT device can be specifically implemented as a passive electronic tag, which can be set on the goods in the logistics warehouse. In this case, the remote unit can also implement some edge computing functions to facilitate the operation and management of the logistics warehouse. For example, the method can also include the following steps:

[0102] Step 1c: The remote unit obtains the inventory list.

[0103] Among them, the inventory list is used to indicate the entry and exit status of goods in the logistics warehouse, and passive electronic tags are set on the goods in the logistics warehouse.

[0104] For example, the baseband unit may have a communication connection with a management system of a logistics warehouse, and the management system may synchronize the inventory list to the remote unit through the baseband unit.

[0105] For another example, a logistics warehouse may include an outbound port and an inbound port. An inbound barcode scanner may be provided at the inbound port. When goods enter the warehouse, the inbound barcode scanner may scan and obtain the barcode on the goods to record the entry. When goods leave the warehouse, the outbound barcode scanner may scan and obtain the barcode on the goods to record the exit. The remote unit may have a communication connection with the inbound barcode scanner and the outbound barcode scanner, and determine and dynamically update the inventory list based on the inbound record and the outbound record.

[0106] Step 2c: The remote unit determines the existence of the target passive electronic tag in the logistics warehouse based on the inventory list, and outputs a prompt message.

[0107] The target passive electronic tag is a passive electronic tag whose goods are shown as not shipped out in the inventory list and to which the remote unit does not send an uplink signal after sending a driving signal; the prompt information is used to prompt that the target passive electronic tag is faulty.

[0108] For example, the logistics warehouse may also include a terminal device of a staff member, and the terminal unit may send a prompt message to the terminal device of the staff member. The prompt message may be, for example, a pop-up window, a text message, or a voice message, etc. This embodiment of the application does not limit this.

[0109] In the passive IoT device driving method provided in the embodiment of the present application, the remote unit can also obtain the inventory list, and determine the target passive electronic tag whose goods are shown as not shipped out in the inventory list and have no feedback after the remote unit is driven, and output a prompt message to prompt that the target passive electronic tag is faulty. By comparing the feedback of the inventory list and the passive electronic tag, the passive electronic tag fault can be discovered in time, which helps to quickly locate and solve the fault, reduce the impact of equipment failure on the normal operation of the business, and help maintain the normal business operation of the logistics warehouse. In addition, the remote unit reduces the need for manual detection and reduces operation and maintenance costs through automated and intelligent fault detection.

[0110] The above-mentioned passive IoT device driving method provided by the embodiment of the present application is introduced by taking the remote unit in the room distribution 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 baseband unit in the room distribution system (such as the above-mentioned BBU 100). Figure 4 A schematic diagram of another passive IoT device driving method provided in an embodiment of the present application. Figure 4 As shown, the method comprises the following steps:
