[0041] The Beidou satellite navigation system provides high-precision positioning services outdoors, but in indoor environments, it is difficult to achieve effective positioning because the satellite signal is severely attenuated by buildings. While Wi-Fi, Bluetooth, and UWB positioning technologies have certain application potential indoors, signal coverage and stability are still insufficient.

[0042] In an exemplary technology, the present application embodiment provides an IT asset location tracking system based on BDS and Bluetooth technology, such as Figure 1 As shown, it includes: a Bluetooth device 10, a positioning device 20, a positioning server 30, and a monitoring system 40. Among them:

[0043] The Bluetooth device 10 is installed indoors. The positioning device 20 is installed on the IT asset. The positioning device 20 supports outdoor communication with the Beidou satellite navigation system 50 to obtain satellite positioning information, and the positioning device 20 supports indoor scanning of the Bluetooth device 10 to obtain Bluetooth positioning information. The positioning server 30 communicates with the positioning device 20. The positioning server 30 is used to determine the location information of the positioning device 20 based on the satellite positioning information and the Bluetooth positioning information, and uses the location information of the positioning device 20 as the location information of the IT asset. The monitoring system 40 communicates with the positioning server 30. The monitoring system 40 is used to receive, store and display the location information of the IT asset.

[0044] The Bluetooth device 10 refers to a device capable of Bluetooth communication with the positioning device 20. The Bluetooth device 10 is fixedly installed at a known position indoors. Based on this, when the IT asset is indoors, the specific position of the IT asset indoors can be determined based on the Bluetooth wireless communication between the Bluetooth device 10 and the positioning device 20. The installation of the positioning device 20 can be determined according to the form of the IT asset. For example, when the IT asset is a notebook, a mobile phone or other device, the positioning device 20 can be a positioning device 20 integrated in the notebook or mobile phone, as long as it can support Bluetooth communication and Beidou satellite navigation system 50 communication.

[0045] Beidou Navigation Satellite System 50 (BDS, also known as COMPASS, Chinese transliteration name: BeiDou) has a global horizontal positioning accuracy of better than 9 meters, a vertical positioning accuracy of better than 10 meters, a speed measurement accuracy of better than 0.2 meters per second, and a timing accuracy of better than 20 nanoseconds. Through the communication between the positioning device 20 and the Beidou Navigation Satellite System 50, IT assets can be accurately positioned outdoors.

[0046] The above-mentioned IT asset location tracking method and system based on BDS and Bluetooth technology, by setting a positioning device 20 that supports satellite communication and Bluetooth communication on the IT asset, can achieve accurate positioning of IT assets based on BDS outdoors and based on Bluetooth indoors during the movement of IT assets, thereby ensuring accurate positioning of IT assets at any location. When the positioning server 30 communicates with the positioning device 20, the satellite positioning information and Bluetooth positioning information fed back by the positioning device 20 can be used to determine the location information of the IT asset and send it to the monitoring system 40. Users can view the location information of the IT asset based on the monitoring system 40 to form spatial information management of the IT asset.

[0047] In one exemplary technique, Figure 2 As shown, the Bluetooth device 10 includes: a plurality of Bluetooth beacons 11. The plurality of Bluetooth beacons 11 are distributedly installed indoors. The positioning device 20 supports scanning the Bluetooth beacons 11 to obtain Bluetooth positioning information.

[0048] Among them, the Bluetooth beacon 11 is a small, low-power Bluetooth device that can continuously broadcast its unique identifier (UUID) and other relevant information (such as location coordinates, signal strength, etc.). The Bluetooth beacon 11 is installed at a fixed location indoors (the location is known), such as on a wall or ceiling, so as to form a stable signal network in the indoor environment. The Bluetooth beacon 11 is distributedly installed in various corners and key locations indoors (such as on the ceiling and walls), which can achieve full coverage and precise positioning indoors. This distribution method ensures that no matter where the IT assets are indoors, they can at least receive signals from one or more Bluetooth beacons 11.

[0049] When the positioning device 20 enters the coverage range of the Bluetooth beacon 11, it starts to scan and receive signals from these Bluetooth beacons 11. The positioning device 20 calculates the relative position of the positioning device 20 relative to these Bluetooth beacons 11 by analyzing the received signal strength, signal arrival time difference (TDOA), signal arrival angle (AOA) and other signals of the Bluetooth beacon 11. Furthermore, the positioning device 20 can also convert these relative positions into absolute coordinates based on triangulation positioning method, fingerprint positioning method, etc., so as to achieve precise positioning.

[0050] Optionally, the Bluetooth beacon 11 may be a Bluetooth beacon 11 that supports Bluetooth 5.1 and above, thereby further improving the stability of signal transmission and the accuracy of positioning.

[0051] In one embodiment, the positioning device 20 includes a positioning card, and the Bluetooth beacon 11 broadcasts a Bluetooth signal. After the positioning card scans the beacon signal, it integrates the beacon broadcast information, and sends the positioning card information and the beacon information forwarded by the positioning card to the positioning server 30 through 4G / 5G or a wired local area network. The data packet is parsed by the positioning alarm algorithm to calculate the specific location of the positioning card (Bluetooth positioning information). Then, the positioning information is sent to the central server of the monitoring system 40. After receiving the location information, the central server will store it in the database. These data are usually stored in the form of timestamps and longitude and latitude coordinates for subsequent analysis and processing.

[0052] In one embodiment, the positioning device 20 starts scanning the Bluetooth beacon 11 only when entering a room, so as to reduce energy consumption.

[0053] The positioning device 20 can determine whether the IT asset is indoors based on the satellite positioning information and pre-stored map information. The map information may include 3D building information.

[0054] In one exemplary technique, Figure 3 As shown, the Bluetooth device 10 includes: a Bluetooth base station ( Figure 3The Bluetooth base station is installed indoors and is equipped with an array antenna for measuring the signal arrival angle. The positioning device 20 includes a Bluetooth tag, and the Bluetooth tag communicates with the Bluetooth base station via Bluetooth wireless communication.

[0055] Among them, the Bluetooth base station is installed indoors, and each Bluetooth base station is equipped with an array antenna (with a known direction) for measuring the angle of arrival (AOA) of the signal. The Bluetooth tag is a small device that conducts Bluetooth wireless communication with the Bluetooth base station. It can be active (with its own power supply, actively sending signals) or passive (sending signals after being activated by an external device). The Bluetooth tag is placed on the IT asset. When the IT asset carries the Bluetooth tag and enters the coverage range of the Bluetooth base station, the Bluetooth tag will establish communication with the base station and send a Bluetooth wireless signal. The array antenna receives the Bluetooth wireless signal from the Bluetooth tag and calculates the arrival angle of the Bluetooth wireless signal by analyzing the time difference or phase difference between the Bluetooth wireless signal reaching different antennas. The precise location of the tag is calculated based on the arrival angle data measured by multiple base stations using algorithms such as triangulation or multilateral positioning.

[0056] The communication between the Bluetooth tag and the base station can be bidirectional, that is, the Bluetooth tag can send a signal to the Bluetooth base station, and the Bluetooth base station can also send instructions or confirmation information to the Bluetooth tag.

[0057] The IT asset location tracking system based on BDS and Bluetooth technology provided in the embodiment of the present application realizes a high-precision indoor positioning function by combining the wireless communication of Bluetooth base stations and Bluetooth tags and the signal measurement technology of array antennas.

[0058] In one embodiment, specifically, a coordinate system can be established with a Bluetooth base station. The Bluetooth tag transmits a radio signal at a position above the ground level. The wireless signal from the Bluetooth tag to the base station is used as a spatial vector. The array antenna of the base station is used to measure the arrival angle (pitch angle and azimuth angle) of the signal to determine the unique signal vector in space. The intersection of the signal vector and the tag plane is the target position of the measurement, that is, the position of the IT asset. A larger coverage area can be achieved by deploying multiple Bluetooth base stations, and the use of multiple Bluetooth base station heading solutions can improve positioning accuracy.

[0059] In an exemplary technology, there are multiple Bluetooth base stations, and the multiple Bluetooth base stations are distributed and installed on the indoor ceiling. The base station on the ceiling can more easily cover the entire indoor space and reduce blind spots. In an indoor environment, the signal propagating downward from the ceiling is often more stable than propagating from the ground or the side because there are fewer obstacles on the ceiling. When an IT asset equipped with a Bluetooth tag moves indoors, it can establish communication with multiple base stations, thereby providing more accurate location information.

[0060] In an exemplary technology, the positioning server 30 is used to determine the location information of the positioning device 20 according to the Bluetooth positioning information corresponding to multiple Bluetooth base stations.

[0061] Among them, the positioning server 30 has a powerful computing capability, can process a large amount of data in real time, and quickly calculate the location information of the positioning device 20, which is suitable for the location information calculation scenario of massive IT assets. The positioning server 30 uses these Bluetooth positioning information, combined with triangulation positioning, multilateral positioning, fingerprint positioning and other algorithms, to calculate the three-dimensional position (x, y, z) of the positioning device 20.

[0062] In one exemplary technique, Figure 2 As shown, the monitoring system 40 includes: a LAN switch 41, a client 42, and a PC positioning platform 43. Among them:

[0063] The LAN switch 41 communicates with the positioning device 20 via a VPN network, and the LAN switch 41 communicates with the positioning server 30. The client 42 communicates with the LAN switch 41. The PC positioning platform 43 communicates with the client 42.

[0064] The LAN switch 41 not only communicates with the positioning device 20 through the VPN network, but also directly communicates with the positioning server 30, playing the role of data transfer and routing. VPN (Virtual Private Network) is a technology that establishes an encrypted channel on a public network to achieve secure communication between remote users or devices.

[0065] Specifically, the LAN switch 41 communicates with the positioning device 20 via a VPN network, ensuring the security and reliability of data transmission. The client 42 communicates with the positioning server 30 via the LAN switch 41 to obtain and display the location information of the positioning device 20.

[0066] The PC positioning platform 43 is a PC-based application or software platform 43 that supports monitoring functions. The PC positioning platform 43 communicates with the client 42, receives and processes location information from the client 42, and provides additional functions such as a visualization interface, an alarm function, and a historical track query.

[0067] In an exemplary technology, the location information of the IT asset includes time data and coordinate data, and the monitoring system 40 is further used to generate and display the current location and historical location trajectory of the IT asset based on the stored time data and coordinate data.

[0068] The location information of IT assets refers to the geographical location and spatial location of IT assets at a specific point in time. Location information consists of time data and coordinate data. Time data records the time point when the location information is collected, while coordinate data describes the specific location of the IT asset at a specific point in time (such as longitude and latitude, floor, room number, etc.). The monitoring system 40 stores the location information of IT assets, and generates and displays the current location of the IT assets (the location of the IT assets at the time of the most recent location information collection) and the historical location trajectory of the IT assets based on this location information (the path that the IT assets have moved through in the past period of time, usually represented by a series of coordinate points arranged in chronological order, and by connecting these coordinate points to form a continuous trajectory line, thereby intuitively showing the movement of IT assets). Users can intuitively understand the trajectory of IT assets in the monitoring system 40 and realize the spatial management of IT assets.

[0069] Among them, the current location and historical location trajectory of IT assets can be displayed in the form of charts, maps, etc., which is convenient for users to view and manage.

[0070] In an exemplary technology, the positioning device 20 is used to package satellite positioning information and Bluetooth positioning information into a data packet and send the data packet to the positioning server 30; the positioning server 30 is used to parse the data packet according to the positioning engine algorithm to calculate the location information of the positioning device 20.

[0071] Specifically, the positioning device 20 packages the satellite positioning information and Bluetooth positioning information from different sources into a data packet so as to send it to the positioning server 30 for further processing. The data packet may also include other relevant information, such as timestamp, device ID, signal strength, etc., which helps the positioning server 30 to solve the position more accurately. The data packet from the positioning device 20 is received and parsed and the position is solved according to the positioning engine algorithm. The positioning server 30 calculates the exact location of the positioning device 20 using the positioning information in the data packet according to the positioning engine algorithm. Optionally, the positioning server 30 may also have functions such as data storage, data analysis and report generation so that users can easily view and manage positioning data.

[0072] In an exemplary technology, the positioning device 20 includes a GPS module. The Global Positioning System (GPS) is a satellite-based positioning system that can provide high-precision location information. The GPS module is installed on the monitored IT asset to receive signals from GPS satellites (in this case, the Beidou satellite positioning system) and calculate the latitude and longitude coordinates of the IT asset. The GPS module sends this positioning information to the server of the monitoring system 40 through wireless communication technology (such as GSM, GPRS, LTE).

[0073] In an exemplary technology, a method for tracking the location of an IT asset based on BDS and Bluetooth technology is provided, which is applied to the above-mentioned IT asset location tracking system based on BDS and Bluetooth technology. The method includes:

[0074] The positioning server 30 determines the location information of the positioning device 20 according to the satellite positioning information and the Bluetooth positioning information;

[0075] The positioning server 30 uses the position information of the positioning device 20 as the position information of the IT asset and sends it to the monitoring system 40;

[0076] Monitoring system 40 stores and displays location information of IT assets.

[0077] Regarding the implementation of each step in the method, reference may be made to the description in the above embodiments and will not be repeated here.

[0078] The IT asset location tracking method and system based on BDS and Bluetooth technology provided in the embodiment of the present application ensures high-precision positioning of IT assets during movement by integrating Beidou outdoor positioning and indoor Bluetooth positioning, and realizes spatial management of IT assets by uploading information to the monitoring system 40.

[0079] In one embodiment, Figure 4 As shown, the LAN switch 41 also communicates with the business server 90, which can be used to record IT asset borrowing information, change information, and other IT asset information change information caused by business execution. The monitoring system 40 can also further generate ledger track maps, equipment track maps, equipment changes, equipment borrowing records, equipment stay time monitoring, etc. based on the received IT asset location information, and the relevant content can be viewed in the PC space location function section. On the monitoring system 40 side, equipment anomaly detection records, application records, equipment space location dashboards, etc. can also be generated, and the relevant content can be viewed in the PC resource monitoring function section.
