[0058] As Figure 1 shown, the asset positioning and tracking method includes: step 110 and step 120.

[0059] Step 110: When the asset positioning device detects an abnormal movement of the target asset, generate a movement warning event and send it to the asset tracking platform.

[0061] In actual execution, the target asset can be in a stationary state or a moving state. The target asset can be a commodity, a device, a livestock animal, etc., and the present application does not make specific restrictions on this.

[0062] In actual execution, the asset positioning device in the target asset can obtain the positioning data of the target asset based on at least one of the global satellite navigation module, WIFI module or LORA base station module, and determine whether the target asset moves abnormally based on the positioning data of the target asset. In the case of abnormal movement of the target asset, the asset positioning device can generate a movement warning event and send it to the asset tracking platform.

[0063] In actual execution, the asset positioning device can send the movement warning event to the asset tracking platform based on a preset cycle. The asset positioning device can also send the movement warning event to the asset tracking platform when a communication connection is established with the asset tracking platform.

[0064] Step 120: The asset tracking platform obtains the movement track based on the movement warning event, and obtains the asset tracking result based on the movement track and the preset track; the asset tracking result is used to indicate whether there is a risk of the target asset being missing.

[0065] In actual execution, the asset tracking platform can obtain the movement track of the target asset based on the movement warning event. The movement track can represent the movement route of the target asset, and the movement track can include at least one discontinuity point.

[0066] In some embodiments, the asset tracking platform can parse the movement warning event, obtain at least one discontinuity point of the movement of the target asset, and obtain the movement track based on the at least one discontinuity point.

[0067] In some embodiments, the asset tracking platform can obtain at least one discontinuity point of the movement of the target asset recorded by the global satellite navigation module, WIFI module or LORA base station module based on the movement warning event generated by any one of the global satellite navigation module, WIFI module or LORA base station module, and obtain the movement track based on the at least one discontinuity point.

[0068] In actual execution, the asset tracking platform can compare the movement track with the preset track, and obtain the asset tracking result indicating whether there is a risk of the target asset being missing based on the comparison result.

[0069] In some embodiments, the asset tracking platform can calculate the difference between the movement track and the preset track, and obtain the asset tracking result indicating whether there is a risk of the target asset being missing based on the difference calculation result.

[0070] According to the asset positioning and tracking method of the present application, through an asset positioning device including a global satellite navigation module, a WIFI module, and a LORA base station module, when an abnormal movement of a target asset is detected, a movement warning event is generated and sent to an asset tracking platform. The asset tracking platform obtains a movement trajectory based on the movement warning event, and obtains an asset tracking result indicating whether there is a missing risk for the target asset based on the movement trajectory and a preset trajectory, so as to perform communication positioning on the target asset based on the asset positioning device including the global satellite navigation module, the WIFI module, and the LORA base station module, thereby expanding the asset positioning range.

[0071] In some embodiments, actual positioning data may be obtained by at least one of the global satellite navigation module, the WIFI module, or the LORA base station module; when the difference between the actual positioning data and the target position data is greater than or equal to a first threshold, a movement warning event is generated based on the actual positioning data and sent to the asset tracking platform.

[0073] In actual execution, the actual positioning data may be the coordinates of the actual geographical location where the target asset is located, such as longitude and latitude coordinates, etc.

[0074] In some embodiments, after the asset positioning device obtains the actual positioning data through at least one of the global satellite navigation module, the WIFI module, or the LORA base station module, the asset positioning device may obtain the difference between the actual positioning data and the target position data. The target position data may include the coordinates of the preset geographical location where the target asset is located, such as longitude and latitude coordinates, etc.

[0075] In some embodiments, the asset positioning device may obtain the difference between the coordinates of the actual geographical location where the target asset is located and the coordinates of the preset geographical location, so as to obtain the difference between the actual positioning data and the target position data.

[0076] In some embodiments, when the difference between the actual positioning data and the target position data is greater than or equal to the first threshold, the asset positioning device may generate a movement warning event based on the actual positioning data and send it to the asset tracking platform. For example, when the difference between the actual positioning data and the target position data is greater than or equal to 500 meters, the asset positioning device may generate a movement warning event based on the actual positioning data and send it to the asset tracking platform.

[0077] In actual execution, the mobile alarm event may include the alarm time, actual positioning data, target location data, etc. The alarm time represents the time when the asset positioning device generates the mobile alarm event.

[0078] According to the asset positioning and tracking method of the present application, through an asset positioning device including a global satellite navigation module, a WIFI module, and a LORA base station module, actual positioning data is obtained; when the difference between the actual positioning data and the target location data is greater than or equal to the first threshold, a mobile alarm event is generated based on the actual positioning data and sent to the asset tracking platform. The asset tracking platform obtains the mobile trajectory based on the mobile alarm event, and based on the mobile trajectory and the preset trajectory, obtains an asset tracking result for indicating whether there is a missing risk of the target asset, so as to perform communication positioning on the target asset based on the asset positioning device including the global satellite navigation module, the WIFI module, and the LORA base station module to expand the asset positioning range.

[0079] In some embodiments, when the satellite signals received by the global satellite navigation module meet the requirements of the positioning accuracy, the global satellite navigation module can obtain the actual positioning data of the target asset.

[0080] In actual execution, the satellite signals may be Global Positioning System (GPS) satellite signals or Beidou satellite signals, and the global satellite navigation module can be used to receive Global Positioning System (GPS) satellite signals and Beidou satellite signals. The global satellite navigation module can obtain the actual positioning data of the target asset based on the GPS satellite signals or Beidou satellite signals.

[0082] In actual implementation, the wireless network information may include a wireless access point (AP), a media access control address (MAC), the wireless network signal strength, etc. The WIFI module can pre-store a location mapping library based on the MAC address. The location mapping library based on the MAC address includes the MAC addresses of multiple wireless networks and the location coordinates corresponding to the MAC addresses. The WIFI module can obtain in real time the wireless network information such as the detected wireless access point (AP), the media access control address (MAC), and the wireless network signal strength. Based on the wireless network information, it compares and searches the location mapping library based on the MAC address, and determines the location coordinates corresponding to the found wireless network information as the actual positioning data of the target asset.

[0083] In some embodiments, when the satellite signals received by the global satellite navigation module do not meet the requirements of the positioning accuracy and the WIFI module cannot obtain the wireless network information, the LORA base station module can obtain the base station communication information and generate the actual positioning data based on the base station communication information; the base station communication information includes the communication round-trip time and the communication signal strength with at least two base stations around the target asset.

[0084] In actual implementation, the base station communication information may include the communication round-trip time (RTT) with the LORA base station and the communication signal strength (such as the RSSI signal strength). The LORA base station module can pre-store the location coordinates of all LORA base stations, and obtain the RTT and the communication signal strength of the communication with each LORA base station during the communication with at least two LORA base stations. Based on the RTT and the communication signal strength of the communication with each LORA base station, the distance between each LORA base station is obtained, and based on the distances between all the LORA base stations for communication and the location coordinates of each LORA base station, the actual positioning data of the target asset is obtained in a three-point positioning manner.

[0085] In some embodiments, the interference can be reduced by controlling the signal transmission power of the LORA base station.

[0086] According to the asset positioning and tracking method of the present application, when the satellite signals received by the global satellite navigation module meet the positioning accuracy requirements, the global satellite navigation module obtains the actual positioning data of the target asset; when the satellite signals received by the global satellite navigation module do not meet the positioning accuracy requirements and the WIFI module obtains the wireless network information, the WIFI module generates the actual positioning data based on the wireless network information; when the satellite signals received by the global satellite navigation module do not meet the positioning accuracy requirements and the WIFI module cannot obtain the wireless network information, the LORA base station module obtains the base station communication information and generates the actual positioning data based on the base station communication information, so that when the satellite signals received by the global satellite navigation module do not meet the positioning accuracy requirements, the actual positioning data can still be obtained through the WIFI module or the LORA base station module, so as to solve the problem of being unable to obtain the actual positioning data in the case of no satellite signal.

[0087] In some embodiments, the WIFI module can obtain the target routing information table; the target routing information table includes the media access control addresses, wireless network signal strengths, and position coordinates corresponding to the wireless networks of at least two wireless network access points or wireless network routers obtained by the WIFI module; when the change of the target routing information table based on the pre-stored initial routing information table is greater than the second threshold, a mobile alarm event is generated based on the target routing information table and sent to the asset tracking platform.

[0088] In actual execution, the pre-stored initial routing information table may include the media access control addresses, wireless network signal strengths, and position coordinates corresponding to the wireless networks of at least two wireless network access points or wireless network routers obtained by the WIFI module in the asset positioning device when the target asset is located at the initial position.

[0091] In some embodiments, the difference between the coordinate positions corresponding to the routing information in the target routing information table and the coordinate positions corresponding to the routing information in the initial routing information table can be obtained, and when the difference is greater than the second threshold, a mobile alarm event is generated based on the target routing information table and sent to the asset tracking platform.

[0092] In some embodiments, the asset tracking platform can parse mobile alarm events to obtain mobile anomaly breakpoints; the mobile anomaly breakpoints include the position coordinates of the target asset moving abnormally at the target moment; the asset tracking platform generates a mobile trajectory of the actual movement of the target asset within the target time period based on the mobile anomaly breakpoints; when the difference between the mobile trajectory and the preset trajectory is greater than or equal to a third threshold, an asset tracking result indicating that the target asset has a high risk of disappearance is generated. Among them, the mobile alarm events include a first alarm event, a second alarm event, and a third alarm event; the first alarm event is a mobile alarm event generated when it is detected that the target asset moves abnormally based on the actual positioning data obtained by the global satellite navigation module; the second alarm event is a mobile alarm event generated when it is detected that the target asset moves abnormally based on the actual positioning data obtained by the WIFI module; the third alarm event is a mobile alarm event generated when it is detected that the target asset moves abnormally based on the actual positioning data obtained by the WIFI module or the target routing information table.

The third alarm event can be a mobile alarm event generated by the LORA base station module when the difference between the actual positioning data and the target position data is greater than or equal to a first threshold.

[0094] In some embodiments, the asset tracking platform can arrange at least one first alarm event, at least one second alarm event, and at least one third alarm event according to the alarm time, and sequentially parse each first alarm event, second alarm event, and third alarm event respectively to obtain mobile anomaly breakpoints. In some embodiments, the asset tracking platform can parse the first alarm event to obtain the actual positioning data of the target asset at a certain moment, compare the actual positioning data at that moment with the target position data, and obtain the mobile anomaly breakpoint based on the comparison result.

[0095] In some embodiments, the asset tracking platform can parse at least one second alarm event to obtain the actual positioning data of the target asset at a certain moment, compare the actual positioning data at that moment with the target position data, and obtain the mobile anomaly breakpoint based on the comparison result.

[0096] In some embodiments, the asset tracking platform may analyze at least one third warning event, obtain the actual positioning data of the target asset at a certain moment, compare the actual positioning data at that moment with the target location data, and obtain a mobile anomaly breakpoint based on the comparison result.

[0097] In some embodiments, the asset tracking platform may generate a movement trajectory of the actual movement of the target asset within the target time period based on the mobile anomaly breakpoint. In some embodiments, the asset tracking platform may connect at least one mobile anomaly breakpoint based on the target moment corresponding to at least one mobile anomaly breakpoint to generate a movement trajectory of the actual movement of the target asset within the target time period. The target time period includes the target moments corresponding to each mobile anomaly breakpoint among at least one mobile anomaly breakpoint.

[0098] In some embodiments, the asset tracking platform may compare the movement trajectory with a preset trajectory. When the difference between the movement trajectory and the preset trajectory is greater than or equal to a third threshold, an asset tracking result indicating that the target asset has a high risk of being missing is generated.

[0099] In some embodiments, the difference between each mobile anomaly breakpoint in the movement trajectory and a preset breakpoint may be obtained, and then the differences between each mobile anomaly breakpoint and the preset breakpoint are accumulated to obtain the total difference as the difference between the movement trajectory and the preset trajectory. When the difference between the movement trajectory and the preset trajectory is greater than or equal to a third threshold, an asset tracking result indicating that the target asset has a high risk of being missing is generated.

[0100] In some embodiments, the difference between the last mobile anomaly breakpoint in the movement trajectory and the preset breakpoint may be obtained as the difference between the movement trajectory and the preset trajectory. When the difference between the movement trajectory and the preset trajectory is greater than or equal to a third threshold, an asset tracking result indicating that the target asset has a high risk of being missing is generated.

[0102] In some embodiments, the asset tracking platform can parse the first warning event to obtain a mobile breakpoint; when the distance between the coordinates of the mobile breakpoint and a first preset coordinate point is greater than a fourth threshold, the mobile breakpoint is determined as a mobile abnormal breakpoint.

[0132] To better understand the asset positioning and tracking method provided by the embodiments of the present application, the following further elaboration is provided. It should be understood that the following discussion is only exemplary.

[0133] This application provides an asset positioning and tracking method, and the specific steps can be as follows Figure 3 as shown:

[0134] Step 310: When the satellite signals received by the global satellite navigation module meet the requirements of positioning accuracy, the global satellite navigation module obtains the actual positioning data of the target asset.

[0135] In actual implementation, the satellite signals can be Global Positioning System (GPS) satellite signals or Beidou satellite signals, and the global satellite navigation module can be used to receive Global Positioning System (GPS) satellite signals and Beidou satellite signals. The global satellite navigation module can obtain the actual positioning data of the target asset based on GPS satellite signals or Beidou satellite signals.

[0136] In some embodiments, the global satellite navigation module can sequentially obtain GPS or Beidou satellite signals, and obtain the number of satellites and the quality of satellite signals.

[0137] Step 313: When the satellite signals received by the global satellite navigation module do not meet the requirements of positioning accuracy and the WIFI module obtains wireless network information, the WIFI module generates actual positioning data based on the wireless network information; the wireless network information includes the media control addresses and signal strengths of at least two wireless network access points or wireless network routers around the target asset.

[0138] In actual implementation, the wireless network information can include wireless access points (Access Point, AP), media access control addresses (Media Access Control Address, MAC), wireless network signal strengths, etc. The WIFI module can pre-store a location mapping library based on MAC addresses, and the location mapping library based on MAC addresses includes the MAC addresses of multiple wireless networks and the location coordinates corresponding to the MAC addresses. The WIFI module can obtain wireless network information such as the detected wireless access points (AccessPoint, AP), media access control addresses (Media Access Control Address, MAC), and wireless network signals (such as 2.4GHz Wi-Fi signals) in real time, compare and search the location mapping library based on MAC addresses, and determine the location coordinates corresponding to the found wireless network information as the actual positioning data of the target asset.

[0139] In some embodiments, a location mapping library can be constructed based on a handheld terminal or a drone to obtain wireless access points, MACs, wireless network signal strengths, and corresponding coordinates.

[0140] Step 316: When the satellite signals received by the global satellite navigation module do not meet the positioning accuracy requirements and the WIFI module fails to obtain wireless network information, the LORA base station module obtains base station communication information and generates actual positioning data based on the base station communication information; the base station communication information includes the communication round-trip time and communication signal strength with at least two base stations around the target asset.

[0141] In actual execution, the base station communication information can include the communication round-trip time (Round-Trip Time, RTT) and communication signal strength (such as RSSI signal strength) with the LORA base station. The LORA base station module can pre-store the location coordinates of all LORA base stations and obtain the RTT and communication signal strength (such as the signal strength of sub-GHz band LORA signals) for communication with each LORA base station during communication with at least two LORA base stations. Based on the RTT and communication signal strength for communication with each LORA base station, the distance to each LORA base station is obtained, and based on the distances to all the LORA base stations for communication and the location coordinates of each LORA base station, the actual positioning data of the target asset is obtained by means of trilateration.

[0142] In actual execution, the actual positioning data can be the coordinates of the actual geographical location of the target asset, such as longitude and latitude coordinates, etc.

[0143] In some embodiments, the asset positioning device can include a global satellite navigation module, a WIFI module, a LORA base station module, an energy harvesting front end, an energy harvesting module, a battery module, and a microcontroller unit (MCU). The energy harvesting front end is used to obtain electrical energy based on photovoltaic or vibration, the energy harvesting module is used to transmit the electrical energy obtained by the energy harvesting front end to the battery module, and the microcontroller unit can manage the charging or discharging of the battery module.

[0144] In some embodiments, the asset positioning device can further include an analog-to-digital converter, which can be used to obtain the output current of the energy harvesting front end based on a preset period to identify whether the energy harvesting front end is harvesting energy normally. The analog-to-digital converter can also be used to obtain the input current of the battery module to identify whether there are situations of undervoltage, insufficient power, or overvoltage in the asset positioning module.

[0145] In some embodiments, the asset positioning device can also obtain the energy acquisition situation of the energy acquisition front end (such as vibration or light change situation) and the power status of the battery module through an analog-to-digital converter to predict the operating time of the asset positioning device.

[0146] Step 319: When the difference between the actual positioning data and the target position data is greater than or equal to the first threshold, generate a first warning event, a second warning event, and a third warning event based on the actual positioning data.

[0147] In some embodiments, when the difference between the actual positioning data and the target position data is greater than or equal to the first threshold, the asset positioning device can generate a movement warning event based on the actual positioning data and send it to the asset tracking platform. For example, when the difference between the actual positioning data and the target position data is greater than or equal to 500 meters, the asset positioning device can generate a movement warning event based on the actual positioning data and send it to the asset tracking platform.

[0148] In actual execution, the first warning event, the second warning event, and the third warning event can all include the warning time, the actual positioning data, the target position data, etc. The warning time represents the time when the asset positioning device generates the movement warning event.

[0149] In some embodiments, when the difference between the actual positioning data of the target asset obtained by the global satellite navigation module and the target position data is greater than or equal to the first threshold, the global satellite navigation module can generate a first warning event.

[0150] In some embodiments, when the difference between the actual positioning data of the target asset obtained by the WIFI module and the target position data is greater than or equal to the first threshold, the global satellite navigation module can generate a second warning event.

[0151] In some embodiments, when the difference between the actual positioning data of the target asset obtained by the LORA base station module and the target position data is greater than or equal to the first threshold, the global satellite navigation module can generate a third warning event.

[0152] Step 322: The asset positioning device scans the base station signal and determines the target base station based on the base station signal.

[0153] In actual execution, the target base station can be a LORA base station.

[0154] In some embodiments, the target base station can be a satellite base station. When the surrounding base station signal cannot be obtained, the asset positioning device can connect to the satellite base station (such as the LORA satellite base station).

[0155] In actual execution, the asset positioning device can scan base station signals and determine the base station with the strongest signal strength among at least one scanned base station signal as the target base station.

[0156] Step 325: The asset positioning device sends a connection establishment request to the target base station.

[0157] Step 328: The target base station performs security verification based on the connection establishment request and, if the verification passes, sends confirmation connection information to the asset positioning device to establish a communication connection with the asset positioning device.

[0158] In some embodiments, after obtaining the connection establishment request sent by the asset positioning device, the target base station can perform security verification based on the connection establishment request, such as verifying the identity of the asset positioning device. If the verification passes, it sends confirmation connection information to the asset positioning device to establish a communication connection with the asset positioning device.

[0159] In some embodiments, if the asset positioning device fails to establish a communication connection with the target base station, the asset positioning device stores a mobile warning event.

[0160] In some embodiments, when the target base station performs security verification based on the connection establishment request and, if the verification fails, sends rejection connection information to the asset positioning device, the asset positioning device fails to establish a communication connection with the target base station.

[0161] In some embodiments, if the asset positioning device fails to establish a communication connection with the target base station, the asset positioning device can store the mobile warning event and, when the communication connection with the target base station is successfully established in the next cycle, send the mobile warning event to the target base station so that the target base station forwards the mobile warning event to the asset tracking platform.

[0162] Step 331: The asset positioning device sends the first warning event, the second warning event, and the third warning event to the target base station so that the target base station forwards the mobile warning event to the asset tracking platform.

[0163] Step 334: The asset tracking platform analyzes the first warning event to obtain the mobile discontinuity point.

[0164] In actual execution, after obtaining the first warning event generated by the global satellite navigation module, the asset tracking platform can, based on the actual positioning data in the first warning event, obtain the mobile discontinuity point representing the moving coordinates of the target asset at the target moment, and obtain the distance between the coordinates of the mobile discontinuity point and the first preset coordinate point. The first preset coordinate point can be the preset coordinate point of the target asset at the target moment.

[0165] Step 337: When the distance between the coordinates of the moving breakpoint and the first preset coordinate point is greater than the fourth threshold, determine the moving breakpoint as a moving abnormal breakpoint.

[0166] In some embodiments, when the distance between the coordinates of the moving breakpoint and the first preset coordinate point is greater than the fourth threshold, determine the moving breakpoint as a moving abnormal breakpoint. For example, when the distance between the coordinates of the moving breakpoint and the first preset coordinate point is greater than 50 meters, determine the moving breakpoint as a moving abnormal breakpoint.

[0167] Step 340: The asset tracking platform analyzes the second alarm event to obtain the moving breakpoint.

[0168] In actual execution, after obtaining the second alarm event generated by the WIFI module, the asset tracking platform can, based on the actual positioning data in the second alarm event, obtain the moving breakpoint representing the moving coordinates of the target asset at the target moment, and obtain the distance between the coordinates of the moving breakpoint and the second preset coordinate point. The second preset coordinate point can be the preset coordinate point of the target asset at the target moment.

[0169] Step 343: When the distance between the coordinates of the moving breakpoint and the second preset coordinate point is greater than the fifth threshold, determine the moving breakpoint as a moving abnormal breakpoint.

[0170] In some embodiments, when the distance between the coordinates of the moving breakpoint and the second preset coordinate point is greater than the fifth threshold, determine the moving breakpoint as a moving abnormal breakpoint. For example, when the distance between the coordinates of the moving breakpoint and the second preset coordinate point is greater than 40 meters, determine the moving breakpoint as a moving abnormal breakpoint.

[0171] Step 346: The asset tracking platform analyzes the third alarm event to obtain the moving breakpoint.

[0172] In actual execution, after obtaining the third alarm event generated by the LORA base station module, the asset tracking platform can, based on the actual positioning data in the third alarm event, obtain the moving breakpoint representing the moving coordinates of the target asset at the target moment, and obtain the distance between the coordinates of the moving breakpoint and the third preset coordinate point. The third preset coordinate point can be the preset coordinate point of the target asset at the target moment.

[0173] Step 349: When the distance between the coordinates of the moving breakpoint and the third preset coordinate point is greater than the sixth threshold, determine the moving breakpoint as a moving abnormal breakpoint.

[0174] In some embodiments, when the distance between the coordinates of the movement discontinuity point and the third preset coordinate point is greater than the sixth threshold, the movement discontinuity point is determined as a movement abnormal discontinuity point. For example, when the distance between the coordinates of the movement discontinuity point and the third preset coordinate point is greater than 300 meters, the movement discontinuity point is determined as a movement abnormal discontinuity point.

[0175] Step 352: The asset tracking platform generates a movement trajectory of the target asset's actual movement within the target time period based on the movement abnormal discontinuity point.

[0176] In some embodiments, the asset tracking platform may generate a movement trajectory of the target asset's actual movement within the target time period based on the movement abnormal discontinuity point. In some embodiments, the asset tracking platform may connect at least one movement abnormal discontinuity point based on the target time corresponding to at least one movement abnormal discontinuity point to generate a movement trajectory of the target asset's actual movement within the target time period. The target time period includes the target time corresponding to each movement abnormal discontinuity point among at least one movement abnormal discontinuity point.

[0177] Step 355: When the difference between the movement trajectory and the preset trajectory is greater than or equal to the third threshold, an asset tracking result indicating that the target asset has a high risk of being missing is generated.

[0178] In some embodiments, the difference between each movement abnormal discontinuity point in the movement trajectory and the preset discontinuity point can be obtained, and then the differences between each movement abnormal discontinuity point and the preset discontinuity point are accumulated to obtain the total difference as the difference between the movement trajectory and the preset trajectory. When the difference between the movement trajectory and the preset trajectory is greater than or equal to the third threshold, an asset tracking result indicating that the target asset has a high risk of being missing is generated.

[0179] In some embodiments, the difference between the last movement abnormal discontinuity point in the movement trajectory and the preset discontinuity point can be obtained as the difference between the movement trajectory and the preset trajectory. When the difference between the movement trajectory and the preset trajectory is greater than or equal to the second threshold, an asset tracking result indicating that the target asset has a high risk of being missing is generated.
