[0058] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0059] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0060] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0061] Monitoring equipment is a recording device that uses a camera to obtain monitoring images within the acquisition range. Monitoring equipment is real-time, and people can use monitoring equipment to view the real-time status of a specified location or area, such as moving objects in the monitoring area, thereby improving the safety of the monitored area. In order to monitor a specified location or area, the monitoring equipment needs to be installed in a fixed position. However, this means that the monitoring equipment can only monitor moving objects within a fixed range, which cannot meet the travel needs of users.

[0062] When users travel, they will carry personal items, such as backpacks and handbags. However, some items are not convenient to bring into some special places, such as airports, museums, power facilities, oil depots, and factory areas. Therefore, users need to place these items in designated locations. However, if unattended, these personal items are easily discarded by others without the user's knowledge, or taken away by illegal persons without authorization, causing property losses.

[0063] In order to protect personal belongings, people can use monitoring equipment to monitor the environment around personal belongings and notify users in time when intruders appear, so that users can return to the location where they placed their personal belongings to take care of their personal belongings. However, monitoring equipment can only be installed in fixed locations, and there are still installation restrictions for some outdoor or indoor scenes. In addition, monitoring equipment has blind spots, and intruders can move around in the blind spots. There are blind spots that cannot be captured during the process of acquiring images. Therefore, monitoring equipment can be avoided by the intruder, which poses certain security risks.

[0064] In order to improve the monitoring accuracy of the monitoring equipment on mobile objects, some embodiments of the present application provide a mobile object monitoring system, which includes a mobile object monitoring device and a controller. The controller establishes a communication connection with the mobile object monitoring device to facilitate receiving monitoring data sent by the mobile object monitoring device. The mobile object monitoring device can be placed in the same place as the user's personal belongings, and uses the personal belongings as the origin of monitoring to monitor the surrounding mobile objects.

[0065] Figure 1 This is a schematic diagram of the structure of the mobile object monitoring device. Figure 1 The mobile object monitoring device includes a first radar 1, an infrared camera 2, a support rod 3, a second radar 4 and a wireless carrier device 5, wherein the support rod 3 is the main body of the mobile object monitoring device, and the support rod 3 includes a first end, a rod portion and a second end portion, wherein the second end portion is placed on the ground so that the mobile object monitoring device stands on the ground, and the first radar 1 and the infrared camera 2 are arranged on the first end portion to facilitate the acquisition of monitoring data from a high place. The monitoring accuracy of the second radar 4 and the wireless carrier device 5 is greater than that of the first radar 1 and the infrared camera 2. In order to save the installation space of the mobile object monitoring device, the second radar 4 and the wireless carrier device 5 are arranged on the rod portion of the support rod 3.

[0066] The first radar 1, the infrared camera 2, the second radar 4 and the wireless carrier device 5 can all monitor the moving object, but the monitoring accuracy of the first radar 1, the infrared camera 2, the second radar 4 and the wireless carrier device 5 is different. Among them, the monitoring accuracy of the first radar 1 is 0-100m. The first radar 1 can be a laser radar, which performs physical rotation to perform 3D scanning, comprehensively covers the moving object monitoring equipment and forms a point cloud.

[0067] The wireless carrier device 5 may be a monitoring device using ultra-wideband (UWB) identification and detection technology, and the detection range of such monitoring device is 0-200m. UWB is a wireless carrier communication technology that uses nanosecond non-sinusoidal narrow pulses to transmit data, with an operating frequency band of 3.25GHZ-6.75GHZ, and a typical frequency bandwidth of 500MHZ or 1GHZ, which can accurately obtain monitoring information of mobile objects.

[0068] The infrared camera 2 can obtain thermal imaging images of moving objects through infrared thermal imaging technology. Infrared thermal imaging technology is a passive, non-contact monitoring and identification technology that can monitor the position of moving objects by obtaining the heat inside the moving object's body, and can clearly observe the target to be monitored; it can perform intelligent video monitoring and identification of camouflaged and hidden targets; infrared thermal imaging technology can intuitively display the temperature field on the surface of an object, is not affected by strong light, and can be applied to a variety of environments.

[0069] In some embodiments, the infrared camera 2 has a recognition capability, such as recognizing the type of moving objects, recognizing the identity information of moving objects, etc. Since recognition requires close observation, the recognition distance is smaller than the identification distance. Therefore, the monitoring distance of the infrared camera is 0m-400m, and the identification distance is 0-200m.

[0070] The second radar 4 can use a millimeter wave radar, which uses frequency modulated continuous wave (FMCW) technology and can effectively monitor moving objects in the area. The millimeter wave radar has a speed measurement range of 0±20m / s and an angle measurement resolution of 12deg. The millimeter wave radar has an angular detection range of 90°-150° and a distance detection range of 500-600m.

[0071] Therefore, the monitoring accuracy of the second radar 4 is greater than that of the infrared camera 2, the monitoring accuracy of the infrared camera 2 is greater than that of the wireless carrier device 5, and the monitoring accuracy of the wireless carrier device 5 is greater than that of the first radar. In order to achieve cross-monitoring to improve monitoring accuracy, the first radar 1 is configured to monitor moving objects in the first preset area, the wireless carrier device 5 is configured to monitor moving objects in the second preset area, the infrared camera 2 is configured to monitor moving objects in the third preset area, and the second radar 4 is configured to monitor moving objects in the fourth preset area. Figure 3 As shown, the fourth preset area includes the third preset area, the third preset area includes the second preset area, and the second preset area includes the first preset area.

[0072] In some embodiments, the controller can obtain the activity position of the mobile object through the mobile object monitoring device, and then monitor the mobile object through the first radar 1, infrared camera 2, second radar 4 and wireless carrier device 5 according to the area where the activity position is located to obtain mobile monitoring information.

[0073] In some embodiments, in order to facilitate information transmission between the controller and the mobile object monitoring device, such as Figure 1 As shown, the mobile object monitoring device may also be provided with a wireless transmission device 6, which may be provided on the rod portion of the support rod 3, and the wireless transmission device 6 may include a wireless transmission module such as a Bluetooth module and a WiFi module. The wireless transmission device 6 is configured to send the mobile monitoring information to a terminal device bound to the mobile object monitoring system through the communication channel. The user may establish a binding relationship between the terminal device and the mobile object monitoring device in advance, and view the monitoring screen obtained by the mobile object monitoring device and the corresponding mobile monitoring information in real time through the terminal device.

[0074] In some embodiments, when the mobile object monitoring device is placed outdoors, it may encounter natural factors such as windy and rainy weather or uneven ground. At this time, the mobile object monitoring device is prone to tilt due to the above natural factors, resulting in falling and damage. In order to improve the stability of the placement of the mobile object monitoring device, the mobile object monitoring device may also include a support rod bracket 7, a bracket plate 8 and a ground nail 11, wherein the support rod bracket 7 can be set at the second end of the support rod, and the support rod bracket 7 can include at least three bracket legs to improve the stability of the placement of the mobile object monitoring device.

[0075] The first end surface of the bracket plate 8 can be set at the bottom of the bracket leg of the support rod bracket 7. The bracket plate 8 can be a plate-like structure, and a movably connected between the bracket plate 8 and the support rod bracket 7 can be used to adjust the placement angle of the bracket plate 8 according to the ground on which it is placed, thereby improving the stability of the mobile object monitoring equipment.

[0076] In some embodiments, Figure 2 As shown, a fixing claw 10 can be provided on the second end face of the bracket plate 8. The fixing claw 10 is a tooth-like structure. When placing the mobile object monitoring equipment, the fixing claw 10 can be wedged into the ground, thereby increasing the friction between the support rod bracket 7 and the ground, and improving the stability of the support rod bracket 7 on the smooth plane.

[0077] In some embodiments, a ground nail hole 9 may be further provided on the support plate 8. After the mobile object monitoring device is placed on the ground and kept stable, a ground nail 11 may be passed through the ground nail hole 9 to fix the support plate 8 to the ground. In order to improve the stability of the fixation of the support plate 8, the nail head area of ​​the ground nail 11 is larger than the cross-sectional area of ​​the ground nail hole 9.

[0078] In some embodiments, the mobile object monitoring device can perform a 360° monitoring scan based on the user's personal belongings as the origin, and the scanning area is circular. Since the monitoring accuracy of the first radar 1, the infrared camera 2, the second radar 4 and the wireless carrier device 5 are different, for different areas, devices with corresponding monitoring accuracy can be used for monitoring. For example, the second radar 4 with the highest monitoring accuracy can monitor a wider range and can monitor long-distance moving objects, while the first radar 1 has the lowest monitoring accuracy and can only monitor short-distance moving objects.

[0079] To this end, the first preset area is the monitoring range of the first radar 1 with the personal item as the origin. For the sake of ease of description, the embodiment of the present application defines the location of the personal item as the center location. Figure 4 It is a route map for the mobile object to enter the first preset area. Figure 4 When the mobile object enters the first preset area, the controller can obtain the first area position of the mobile object through the first radar 1, wherein the first area position is the position of the mobile object in the first preset area. Thus, the first distance between the first area position and the center position is calculated, and the first distance is differentially calculated to obtain the first instantaneous speed of the mobile object.

[0080] In some embodiments, when the mobile object enters the second preset area, since the second preset area includes the first preset area, when the mobile object enters the common area of ​​the second preset area and the first preset area, the first radar 1 and the wireless carrier device 5 can monitor the mobile object at the same time. When the mobile object enters the second preset area outside the first preset area, the first radar 1 cannot monitor the mobile object. At this time, the controller can identify the wireless carrier tag of the mobile object through the wireless carrier device 5. If the mobile object carries a wireless carrier tag, the mobile object is marked as a permitted object. If the mobile object does not carry a wireless carrier tag, the mobile object is marked as a non-permitted object. Figure 5 As shown, the wireless carrier device 5 only monitors permitted objects within the second preset area.

[0081] In some embodiments, Figure 6As shown, the controller can also obtain the second area position of the permitted object and the first activity time of the permitted object through the wireless carrier device 5, wherein the second area position is the position of the permitted object in the second preset area, and the first activity time is the time difference between the moment when the permitted object enters the second preset area and the current moment. Then, the controller can calculate the second distance between the second area position and the center position, and differentiate the first activity time according to the second distance to obtain the second instantaneous speed. In this embodiment, since the permitted object is in a moving state, the second distance is a variable that changes in real time. For this reason, the controller can also correct the first activity time according to the time consumed by the movement when the permitted object is in a moving state, and calculate the second instantaneous speed in real time.

[0082] In some embodiments, when the mobile object enters the third preset area, since the third preset area includes the second preset area, when the mobile object enters the common area of ​​the third preset area and the second preset area, the wireless carrier device 5 and the infrared camera 2 can monitor the mobile object at the same time. When the mobile object enters the third preset area outside the second preset area, the wireless carrier device 5 cannot monitor the mobile object. At this time, the controller can obtain a thermal imaging image of the mobile object through the infrared camera 2. The thermal imaging image is generated according to the heat of the mobile object and may include information such as the body shape of the mobile object. The controller can determine the type of the mobile object according to the body shape of the mobile object, and the type may include humans, animals or other objects.

[0083] The monitoring distance of the infrared camera 2 is greater than the recognition distance. The monitoring distance of the infrared camera is 0m-400m, and the recognition distance is 0-200m. To this end, the monitoring area formed by the recognition distance of the infrared camera 2 can cover the second preset area. When the mobile object enters the second preset area, the controller can also obtain the character image of the mobile object through the infrared camera 2, and match the character information in the character database according to the character image. Among them, the character database includes pre-entered character information. The character database can be stored in the memory of the mobile object monitoring device or in the cloud server. If the character database is stored in the cloud server, after obtaining the character image, the controller can initiate an activation request to the cloud server to activate the cloud server and retrieve the character database to match the character information.

[0084] Figure 7 This is a flowchart of how the controller matches character information based on character images. Figure 7If the person information is matched in the person database, it means that the moving object is an object whose person information has been entered. Then, an identity tag can be added according to the moving object to permit the moving object's activities. If the person information is not matched in the person database, the moving object may be an intrusion object. Then, a risk tag can be added according to the moving object and the moving object's activities can be continuously monitored.

[0085] In some embodiments, since the second radar 4 has the highest accuracy, the second radar 4 can monitor the mobile object in the fourth preset area, and the fourth preset area includes the third preset area. When the mobile object enters the third preset area, the controller can also obtain the third area position of the mobile object and the second activity time of the mobile object through the second radar 4, wherein the third area position is the position of the mobile object in the third preset area, and the second activity time is the time difference between the moment when the mobile object enters the third preset area and the current moment. In addition, the controller can calculate the third distance between the third area position and the center position, and the third distance is the straight-line distance from the current position of the mobile object to the center position. After the controller calculates the third distance, it can perform a differential calculation on the second activity time according to the third distance to obtain the third instantaneous speed.

[0086] In some embodiments, when a moving object enters the fourth preset area, the controller can also obtain the fourth area position of the moving object through the second radar 4, and calculate the fourth distance between the fourth area position and the center position, and finally perform differential calculation based on the fourth distance to obtain the fourth instantaneous speed.

[0087] In some embodiments, the mobile object monitoring system may further include an alarm device, which may be electrically connected to the controller. When the mobile object monitoring device detects that a mobile object has entered the first preset area, it indicates that the current mobile object is relatively close to the center position and there is a certain risk. At this time, the controller may control the alarm device to generate an alarm message. The alarm message may include a person image or thermal imaging image captured by the infrared camera 2, and the current instantaneous speed of the mobile object. The alarm message may also include an estimated time for the mobile object to move from the current position to the center position.

[0088] After the alarm device generates the alarm information, the alarm device will return the alarm information to the controller, and the controller can send the alarm information to the user's terminal device to prompt that a moving object moves to the first preset area.

[0089] In some embodiments, the controller can calibrate the mobile monitoring information according to the position of the mobile object. For example, when the mobile object enters the first preset area, the monitoring ranges of the first radar 1, the infrared camera 2, the wireless carrier device 5 and the second radar 4 all cover the first preset area. Therefore, the first radar 1 can obtain the first instantaneous speed of the mobile object, the infrared camera 2 can identify the person information based on the thermal imaging image and the person image, the wireless carrier device 5 can calculate the second instantaneous speed of the mobile object, and the second radar 4 can calculate the third instantaneous speed of the mobile object. The controller can generate mobile monitoring information based on the first instantaneous speed, the second instantaneous speed, the third instantaneous speed and the person information.

[0090] For another example, when a moving object enters the second preset area, the monitoring ranges of the infrared camera 2, the wireless carrier device 5 and the second radar 4 all cover the second preset area, the infrared camera 2 can identify the person information based on the thermal imaging image and the person image, the wireless carrier device 5 can calculate the second instantaneous speed of the moving object, and the second radar 4 can calculate the third instantaneous speed of the moving object. The controller can generate mobile monitoring information based on the second instantaneous speed, the third instantaneous speed and the person information.

[0091] In the above embodiment, the moving object needs to pass through the fourth preset area, the third preset area, the second preset area and the first preset area in sequence to reach the center position. Every time the moving object passes through a preset area and enters the next preset area, a layer of monitoring will be added. The closer the moving object is to the center position, the higher the monitoring accuracy.

[0092] In some embodiments, in order to improve the accuracy of mobile monitoring information, such as Figure 8 As shown, the controller can control the mobile object monitoring device to calculate the first instantaneous speed, the second instantaneous speed, the third instantaneous speed and the fourth instantaneous speed of the mobile object according to the current position of the mobile object, and the average speed of the mobile object can be calculated according to the first instantaneous speed, the second instantaneous speed, the third instantaneous speed and the fourth instantaneous speed. Since the above-mentioned monitoring components can cross-monitor, the mobile monitoring information can be calibrated according to the average speed. For example, for a permitted object, the mobile monitoring information can be calibrated according to the first instantaneous speed, the second instantaneous speed, the third instantaneous speed, the fourth instantaneous speed and the character information. For a non-permitted object, since the wireless carrier device 5 cannot perform monitoring on the non-permitted object, the controller can only calibrate the mobile monitoring information according to the first instantaneous speed, the third instantaneous speed, the fourth instantaneous speed and the character information, thereby improving the accuracy of the mobile monitoring information.

[0093] It can be seen from the above technical solutions that the present application provides a mobile object monitoring system, including a mobile object monitoring device and a controller that establishes a communication connection with the mobile object monitoring device. The mobile object monitoring device monitors mobile objects in different monitoring areas through a first radar, an infrared camera, a second radar, and a wireless carrier device arranged on a support rod, wherein the first radar monitors mobile objects in a first preset area, the wireless carrier device monitors mobile objects in a second preset area, the infrared camera monitors mobile objects in a third preset area, and the second radar monitors mobile objects in a fourth preset area, and the above preset areas are in an inclusive relationship. The present application obtains the active position of the mobile object, and uses a corresponding monitoring method to monitor the mobile object according to the area where the active position is located. Multiple monitoring methods are calibrated with each other to improve the accuracy of monitoring the mobile object.
