Description

Technical Field

[0001] The present invention relates to the field of device retrieval, and particularly to a device retrieval method, apparatus, medium and device. Background Art

[0002] With the continuous development of technology, the management and monitoring requirements for devices and items are increasing day by day, especially in some fields that require strict supervision, such as medical devices and precious items. In these fields, the loss of devices or items not only causes economic losses, but may also affect normal operation and management. However, the existing device monitoring and retrieval technologies have some deficiencies and cannot fully meet the requirements in practical applications.

[0003] Deficiencies of the prior art:

[0004] Limitations of single positioning technology:

[0005] Existing device monitoring systems usually rely on a single positioning technology, such as GPS or base station positioning. These technologies may not be able to provide accurate location information in some environments (such as indoors or signal-blocked areas), resulting in inaccurate or unavailable positioning of devices or items.

[0006] High power consumption problem:

[0007] Existing device monitoring systems often need to perform positioning and communication frequently, which results in high power consumption of the device and short battery life. Especially in some scenarios that require long-term monitoring, the high power consumption problem seriously affects the usability and reliability of the device.

[0008] Difficulty in near-field retrieval:

[0009] When a device is lost, the existing retrieval methods usually rely on remote positioning information. However, in actual operation, users need to perform near-field searches near the last known location of the device. Although existing near-field communication technologies (such as Bluetooth) can be used for short-range positioning of devices, their accuracy is limited and they are easily interfered with in complex environments.

[0010] Management complexity:

[0011] Existing device monitoring systems usually require complex device management and data processing processes. Users need to monitor and manage the location information of devices through multiple platforms or tools. This complexity increases the management cost and operation difficulty and reduces the usability of the system.

[0012] These deficiencies result in the inability of the prior art to accurately retrieve the required devices. Summary of the Invention

[0013] The present invention provides a method, apparatus, medium, and device for retrieving a device to solve the problem in the prior art that the required device cannot be accurately retrieved.

[0014] In a first aspect, the present application provides a method for retrieving a device, including:

[0015] Receiving the first location information of the first device sent by the device management software; wherein, the first location information is generated by the device management software according to the stored historical location information, and the historical location information is sent by the first device to the device management software;

[0016] After establishing a connection with the first device according to the first location information and a preset near-field communication method, performing UWB communication and outputting the real-time location information of the first device.

[0017] The present application first receives the first location information of the first device sent by the device management software. This information is generated based on the historical location information stored in the device management software, and these historical location information are sent by the first device itself and stored in the device management software. This process ensures the accuracy and timeliness of the location information, providing a reliable data basis for subsequent device positioning and retrieval. Subsequently, the system establishes a connection with the first device using a preset near-field communication method and outputs the real-time location information of the first device through UWB communication technology. UWB communication, with its high precision and low power consumption characteristics, further improves the accuracy and efficiency of positioning. In this way, the present application not only realizes the real-time monitoring and precise positioning of the device, but also ensures the convenience and reliability of device management through an efficient communication mechanism. The present application effectively solves the problem in the prior art that the required device cannot be accurately retrieved.

[0018] As a preferred embodiment of the first aspect, the receiving the first location information of the first device sent by the device management software is specifically:

[0019] The first location information includes second location information, third location information, or fourth location information;

[0020] Wherein, the second location information is obtained by GPS or Beidou or GLONASS satellite positioning of the positioning and retrieval module preset in the first device;

[0021] The third location information is obtained by reporting the positioning of the 4G or 5G network base station of the positioning and retrieval module preset in the first device;

[0022] The fourth location information is obtained by scanning the WiFi hotspot of the positioning and retrieval module preset in the first device.

[0023] In this preferred embodiment, when the present application receives the first location information of the first device sent by the receiving device management software, the location information covers multiple sources: the second location information is obtained based on GPS, Beidou or GLONASS satellite positioning, ensuring high-precision positioning in open environments; the third location information is obtained by reporting the positioning of 4G or 5G network base stations, which is suitable for complex scenarios such as building occlusion in urban environments; the fourth location information is obtained by scanning WiFi hotspots, further enhancing the positioning ability in indoor environments. This multi-technology fusion method enables the system to flexibly select the most suitable positioning method under different environmental conditions, thereby improving the accuracy and reliability of the location information and providing solid technical support for device monitoring and recovery.

[0024] As a preferred embodiment of the first aspect, after receiving the first location information of the first device sent by the receiving device management software, it further includes:

[0025] According to the preset mobile network, upload the first location information to a preset server so that the server stores and processes the first location information.

[0026] In this preferred embodiment, the present application realizes the centralized management and efficient utilization of device location information by uploading the first location information of the first device to a preset server for storage and processing. Specifically, after receiving the first location information sent by the receiving device management software, the system uploads this location information to the server using the preset mobile network (such as 4G / 5G). The server, as the centralized storage and processing center of data, can uniformly manage, analyze and back up the location information from multiple devices. This centralized management not only improves the security and reliability of the data, but also facilitates subsequent data query, analysis and monitoring. For example, managers can quickly obtain the historical location trajectory of the device through the server, conduct real-time monitoring and anomaly analysis of the device, thereby effectively improving the efficiency and accuracy of device management. In addition, the processing ability of the server can also support more complex data analysis and prediction functions, providing data support for the optimal scheduling and resource management of the device.

[0027] As a preferred embodiment of the first aspect, after establishing a connection with the first device according to the first location information and the preset near-field communication method and performing UWB communication, the real-time location information of the first device is output, specifically:

[0028] According to the first location information, determine the first estimated area of the first device;

[0029] According to the first estimated area, a preset Bluetooth module, and a preset near-field communication method, after scanning and identifying the broadcast information of the first device, establish a Bluetooth connection with the positioning and retrieval module of the first device, and communicate with the first device according to a preset first UWB module to obtain the relative position information of the first device;

[0030] Output the real-time positioning information of the first device according to the relative position information.

[0031] In this preferred embodiment, the present application realizes high-precision real-time positioning of the first device by combining estimated area positioning, Bluetooth connection, and UWB communication. Specifically, first, determine the first estimated area of the first device according to the first position information, which provides a general position range for subsequent near-field communication and reduces unnecessary search time. Then, use the preset Bluetooth module and near-field communication method to scan and identify the broadcast information of the first device within the estimated area and establish a Bluetooth connection. This process is not only fast and low-power but also ensures accurate connection with the target device. Subsequently, communicate with the first device through the preset first UWB module to obtain relative position information, further improving the positioning accuracy. Finally, output the real-time positioning information of the first device according to the relative position information, providing accurate device location for users and significantly improving the efficiency and reliability of device retrieval. This multi-step positioning method combines the advantages of different technologies, ensuring both fast positioning and high precision, and is applicable to device monitoring and retrieval scenarios in various complex environments.

[0032] As a preferred embodiment of the first aspect, the specific manner of receiving the first position information of the first device sent by the receiving device management software is as follows:

[0033] Receive the first position information of the first device sent by the receiving device management software according to a preset low-power method and a preset time interval.

[0034] In this preferred embodiment, the system of the present application does not continuously receive position information but receives it according to a preset low-power strategy and time interval. This strategy effectively reduces the energy consumption of the device during data transmission, extends the battery life of the device, and makes it more suitable for long-term monitoring and management tasks. At the same time, by reasonably setting the time interval, the system can ensure the real-time nature of the position information while avoiding resource waste and increased energy consumption caused by overly frequent data transmission. This design that balances energy consumption and information update frequency not only improves the feasibility and economy of the device in practical applications but also enhances the stability and reliability of the entire monitoring system, enabling it to adapt to more application scenarios, such as mobile devices with high battery life requirements or usage in remote areas.

The present application first receives the first location information of the first device sent by the device management software. This information is generated based on the historical location information stored in the device management software, and these historical location information are sent by the first device itself and stored in the device management software. This process ensures the accuracy and real-time nature of the location information, providing a reliable data basis for subsequent device positioning and retrieval.

[0073] S01: Receive the first location information of the first device sent by the device management software; wherein, the first location information is generated by the device management software according to the stored historical location information, and the historical location information is sent by the first device to the device management software.

[0074] As a preferred embodiment of Embodiment 1, the receiving of the first location information of the first device sent by the device management software is specifically:

[0075] The first location information includes second location information, third location information or fourth location information;

[0076] Wherein, the second location information is obtained by GPS or Beidou or GLONASS satellite positioning of the preset positioning and retrieving module in the first device;

[0077] The third location information is reported and obtained by 4G or 5G network base station positioning of the preset positioning and retrieving module in the first device;

[0078] The fourth location information is obtained by WiFi hotspot scanning of the preset positioning and retrieving module in the first device.

[0079] In this preferred embodiment, when the present application receives the first location information of the first device sent by the receiving device management software, the location information covers multiple sources: the second location information is obtained based on GPS, Beidou or GLONASS satellite positioning, ensuring high-precision positioning in open environments; the third location information is obtained by reporting the positioning of 4G or 5G network base stations, which is suitable for complex scenarios such as building occlusion in urban environments; the fourth location information is obtained by scanning WiFi hotspots, further enhancing the positioning ability in indoor environments. This multi-technology fusion method enables the system to flexibly select the most suitable positioning method under different environmental conditions, thereby improving the accuracy and reliability of the location information and providing solid technical support for device monitoring and recovery.

[0080] Furthermore, after the first location information of the first device sent by the receiving device management software, it further includes:

[0081] According to the preset mobile network, upload the first location information to a preset server so that the server stores and processes the first location information.

[0082] By uploading the first location information of the first device to a preset server for storage and processing, the present application realizes the centralized management and efficient utilization of device location information. Specifically, after receiving the first location information sent by the receiving device management software, the system uses the preset mobile network (such as 4G / 5G) to upload this location information to the server. As the centralized storage and processing center of data, the server can uniformly manage, analyze and back up the location information from multiple devices. This centralized management not only improves the security and reliability of the data, but also facilitates subsequent data query, analysis and monitoring. For example, managers can quickly obtain the historical location trajectory of the device through the server, conduct real-time monitoring and anomaly analysis of the device, thereby effectively improving the efficiency and accuracy of device management. In addition, the processing ability of the server can also support more complex data analysis and prediction functions, providing data support for the optimized scheduling and resource management of the device.

[0083] S02: After establishing a connection with the first device according to the first location information and the preset near-field communication method, perform UWB communication and output the real-time location information of the first device.

[0084] As a preferred embodiment of Embodiment 1, the step of performing UWB communication and outputting the real-time location information of the first device after establishing a connection with the first device according to the first location information and the preset near-field communication method is specifically:

[0085] After establishing a connection with the first device according to the first position information and a preset near-field communication method, UWB communication is performed to output the real-time positioning information of the first device, specifically as follows:

[0086] Determine a first estimated area of the first device according to the first position information;

[0087] According to the first estimated area, a preset Bluetooth module, and a preset near-field communication method, scan and identify the broadcast information of the first device, establish a Bluetooth connection with the positioning and retrieval module of the first device, and communicate with the first device according to a preset first UWB module to obtain the relative position information of the first device;

[0088] Output the real-time positioning information of the first device according to the relative position information.

[0089] More specifically, after the present application obtains the position information of the device or item to be retrieved through device management software, the retrieval device arrives at that position. The retrieval device uses its Bluetooth module to scan the broadcast information of the positioning and retrieval module and establishes a Bluetooth connection after discovering the target device. During this process, the retrieval device can display the approximate distance from the target device according to the received broadcast signal strength. Both the retrieval device and the positioning and retrieval device are equipped with power supply batteries, and disposable batteries, rechargeable batteries, or built-in batteries can be selected. The positioning and retrieval device can be embedded in the device or item to be retrieved. After the Bluetooth connection is established, the retrieval device activates its UWB module and notifies the positioning and retrieval device to activate its UWB module through Bluetooth, and then realizes high-precision positioning through UWB communication, thereby retrieving the target device.

[0090] In this preferred embodiment, the present application realizes high-precision real-time positioning of the first device by combining estimated area positioning, Bluetooth connection, and UWB communication. Specifically, first, a first estimated area of the first device is determined according to the first position information, which provides a general position range for subsequent near-field communication and reduces unnecessary search time. Then, using the preset Bluetooth module and near-field communication method, scan and identify the broadcast information of the first device within the estimated area and establish a Bluetooth connection. This process is not only fast and low-power but also ensures an accurate connection with the target device. Subsequently, communicate with the first device through the preset first UWB module to obtain relative position information, further improving the positioning accuracy. Finally, output the real-time positioning information of the first device according to the relative position information, providing the user with the accurate device position, significantly improving the efficiency and reliability of device retrieval. This multi-step positioning method combines the advantages of different technologies, ensuring both the rapidity and high precision of positioning, and is applicable to device monitoring and retrieval scenarios in various complex environments.

[0091] As a preferred embodiment of the first embodiment, the first position information of the first device sent by the receiving device management software is specifically:

[0092] According to the preset low-power method and the preset time interval, the receiving device management software sends the first position information of the first device.

[0093] More specifically, in this application, when the processor of the device to be retrieved is in the working state, it will wake up the positioning module, WIFI module, and 4G / 5G module to obtain positioning information and WIFI scan information, and send this information to the server through the 4G / 5G module. After completing the communication, the processor returns to the working state. Subsequently, the processor wakes up the Bluetooth module to enter the broadcast state, and the device to be retrieved starts Bluetooth broadcasting. If no connection request is received within a period of time, the device returns to the working state; if a connection request is received, it enters the retrieval state, and the processor wakes up the UWB module to connect with the recovery device for high-precision positioning. After completing all the work, the device enters the low-power state, at which time all modules and the processor enter the low-power mode. After a certain period of time, the processor will automatically wake up and re-enter the working state, thus realizing low-power cyclic operation.

[0094] In this preferred embodiment, the system of this application does not continuously receive position information, but receives it according to the preset low-power strategy and time interval. This strategy effectively reduces the energy consumption of the device during data transmission, extends the battery life of the device, and makes it more suitable for long-term monitoring and management tasks. At the same time, by reasonably setting the time interval, the system can ensure the real-time nature of the position information while avoiding resource waste and increased energy consumption caused by overly frequent data transmission. This design that balances energy consumption and information update frequency not only improves the feasibility and economy of the device in practical applications but also enhances the stability and reliability of the entire monitoring system, enabling it to adapt to more application scenarios, such as mobile devices with high battery life requirements or situations used in remote areas.

[0095] This application first receives the first location information of the first device sent by the device management software. This information is generated based on the historical location information stored in the device management software, and these historical location information are sent by the first device itself and stored in the device management software. This process ensures the accuracy and timeliness of the location information, providing a reliable data basis for subsequent device positioning and retrieval. Subsequently, the system uses a preset near-field communication method to establish a connection with the first device and outputs the real-time location information of the first device through UWB communication technology. UWB communication, with its characteristics of high precision and low power consumption, further improves the accuracy and efficiency of positioning. In this way, this application not only realizes the real-time monitoring and precise positioning of the device, but also ensures the convenience and reliability of device management through an efficient communication mechanism. This application effectively solves the problem in the prior art that the required device cannot be accurately retrieved.

[0112] The processor 202 of the positioning and retrieving device 20 and the processor 300 of the aforementioned retrieving device 30 can be implemented by software, hardware, firmware, or a combination thereof. Circuits, single or multiple application-specific integrated circuits (ASICs), single or multiple general integrated circuits, single or multiple microprocessors, single or multiple programmable logic devices, or a combination of the aforementioned circuits or devices, or other suitable circuits or devices can be used, so that the processor 202 and the processor 300 can execute the corresponding steps of the position information reporting and retrieving method.

[0113] The receiving module S10 is configured to receive the first position information of the first device sent by the device management software; wherein, the first position information is generated by the device management software according to the stored historical position information, and the historical position information is sent by the first device to the device management software.

[0114] As a preferred embodiment of the second embodiment, the receiving of the first position information of the first device sent by the device management software is specifically:

[0115] The first position information includes second position information, third position information, or fourth position information;

[0116] Wherein, the second position information is obtained by GPS, Beidou, or GLONASS satellite positioning of the preset positioning and retrieving module in the first device;

[0117] The third position information is obtained by reporting the positioning of 4G or 5G network base stations of the preset positioning and retrieving module in the first device;

[0118] The fourth position information is obtained by scanning the WiFi hotspots of the preset positioning and retrieving module in the first device.

[0119] In this preferred embodiment, when the present application receives the first position information of the first device sent by the device management software, the position information covers multiple sources: the second position information is obtained based on GPS, Beidou, or GLONASS satellite positioning, ensuring high-precision positioning in open environments; the third position information is obtained by reporting the positioning of 4G or 5G network base stations, suitable for complex scenarios such as building occlusion in urban environments; the fourth position information is obtained by scanning WiFi hotspots, further enhancing the positioning ability in indoor environments. This multi-technology fusion method enables the system to flexibly select the most suitable positioning method under different environmental conditions, thereby improving the accuracy and reliability of the position information and providing solid technical support for the monitoring and retrieval of devices.

[0120] Further, after sending the first location information of the first device by the receiving device management software, it further includes:

[0121] According to the preset mobile network, upload the first location information to a preset server so that the server stores and processes the first location information.

[0122] In this application, by uploading the first location information of the first device to a preset server for storage and processing, centralized management and efficient utilization of device location information are realized. Specifically, after receiving the first location information sent by the receiving device management software, the system uploads this location information to the server using the preset mobile network (such as 4G / 5G). As the centralized storage and processing center of data, the server can uniformly manage, analyze, and back up the location information from multiple devices. This centralized management not only improves the security and reliability of the data but also facilitates subsequent data query, analysis, and monitoring. For example, managers can quickly obtain the historical location tracks of devices through the server, conduct real-time monitoring and anomaly analysis of the devices, thereby effectively improving the efficiency and accuracy of device management. In addition, the processing power of the server can also support more complex data analysis and prediction functions, providing data support for the optimized scheduling and resource management of devices.

[0123] The communication positioning module S20 is used to establish a connection with the first device according to the first location information and a preset near-field communication method, and then perform UWB communication to output the real-time positioning information of the first device.

[0124] As a preferred embodiment of the second embodiment, the step of establishing a connection with the first device according to the first location information and a preset near-field communication method, then performing UWB communication, and outputting the real-time positioning information of the first device is specifically as follows:

[0125] The step of establishing a connection with the first device according to the first location information and a preset near-field communication method, then performing UWB communication, and outputting the real-time positioning information of the first device is specifically as follows:

[0126] Determine the first estimated area of the first device according to the first location information;

[0127] According to the first estimated area, a preset Bluetooth module, and a preset near-field communication method, scan and identify the broadcast information of the first device, establish a Bluetooth connection with the positioning and retrieval module of the first device, and communicate with the first device according to a preset first UWB module to obtain the relative position information of the first device;

[0128] Output the real-time positioning information of the first device according to the relative position information.

[0129] More specifically, after the device management software of the present application obtains the location information of the device or item to be retrieved, it carries the retrieval device to that location. The retrieval device uses its Bluetooth module to scan the broadcast information of the location retrieval module and establishes a Bluetooth connection after discovering the target device. During this process, the retrieval device can display the approximate distance from the target device according to the received broadcast signal strength. Both the retrieval device and the location retrieval device are equipped with a power supply battery, and disposable batteries, rechargeable batteries or built-in batteries can be selected. The location retrieval device can be embedded in the device or item to be retrieved. After the Bluetooth connection is established, the retrieval device activates its UWB module and notifies the location retrieval device to activate its UWB module through Bluetooth, and then realizes high-precision positioning through UWB communication, so as to retrieve the target device.

[0130] In this preferred embodiment, the present application realizes high-precision real-time positioning of the first device by combining estimated area positioning, Bluetooth connection and UWB communication. Specifically, first, the first estimated area of the first device is determined according to the first position information, which provides a general location range for subsequent near-field communication and reduces unnecessary search time. Then, using the preset Bluetooth module and near-field communication method, the broadcast information of the first device is scanned and identified within the estimated area, and a Bluetooth connection is established. This process is not only fast and low-power, but also ensures accurate connection with the target device. Subsequently, communicate with the first device through the preset first UWB module to obtain relative position information, further improving the positioning accuracy. Finally, the real-time positioning information of the first device is output according to the relative position information, providing the user with the accurate device location, significantly improving the efficiency and reliability of device retrieval. This multi-step positioning method combines the advantages of different technologies, ensuring both the rapidity and high precision of positioning, and is applicable to device monitoring and retrieval scenarios in a variety of complex environments.

[0131] As a preferred embodiment of the second embodiment, the receiving the first position information of the first device sent by the device management software specifically is:

[0132] Receive the first position information of the first device sent by the device management software according to the preset low-power method and the preset time interval.

[0133] More specifically, in the present application, the processor of the retrieval device wakes up the positioning module, WIFI module, and 4G / 5G module during the working state to obtain positioning information and WIFI scan information, and sends this information to the server through the 4G / 5G module. After completing the communication, the processor returns to the working state. Subsequently, the processor wakes up the Bluetooth module to enter the broadcast state, and the retrieval device starts Bluetooth broadcasting. If no connection request is received within a period of time, the device returns to the working state; if a connection request is received, it enters the retrieval state, and the processor wakes up the UWB module to connect with the recovery device for high-precision positioning. After completing all the work, the device enters the low-power state, at which time all modules and the processor enter the low-power mode. After a certain period of time, the processor will automatically wake up and re-enter the working state, thus realizing low-power cyclic operation.

[0134] In this preferred embodiment, the system of the present application does not continuously receive position information, but receives it according to a preset low-power strategy and time interval. This strategy effectively reduces the energy consumption of the device during data transmission, prolongs the battery life of the device, and makes it more suitable for long-term monitoring and management tasks. At the same time, by reasonably setting the time interval, the system can ensure the real-time nature of the position information while avoiding resource waste and increased energy consumption caused by overly frequent data transmission. This design that balances energy consumption and information update frequency not only improves the feasibility and economy of the device in practical applications, but also enhances the stability and reliability of the entire monitoring system, enabling it to adapt to more application scenarios, such as mobile devices with high battery life requirements or situations used in remote areas.

[0135] This device can retrieve the device more accurately by using two modules to work in division and coordination. The present application first receives the first position information of the first device sent by the device management software, which is generated based on the historical position information stored in the device management software, and these historical position information are sent by the first device itself and stored in the device management software. This process ensures the accuracy and real-time nature of the position information, providing a reliable data basis for subsequent device positioning and retrieval. Subsequently, the system uses a preset near-field communication method to establish a connection with the first device and outputs the real-time positioning information of the first device through UWB communication technology. UWB communication, with its characteristics of high precision and low power consumption, further improves the accuracy and efficiency of positioning. In this way, the present application not only realizes the real-time monitoring and precise positioning of the device, but also ensures the convenience and reliability of device management through an efficient communication mechanism. The present application effectively solves the problem in the prior art that the required device cannot be accurately retrieved.
