[0003] In smart office applications, existing radar sensors can be used to control office appliances, such as lights, air conditioners, and fans, based on the detection of users and their trajectories.

[0048] Please refer to Figure 1 This application provides a radar interaction system 100, which includes a radar sensor 1, an interaction platform 2, and a server 3. The interaction platform 2 is communicatively connected to both the radar sensor 1 and the server 3, and is used to configure the radar sensor 1 in response to user operations, while storing the configuration in the server 3. In this embodiment, the configuration is used to configure the desired sensing area 101 and the undesired sensing area 102 of the radar sensor 1, so that the radar sensor 1 only acquires and processes the sensing data of the desired sensing area 101.

[0049] Please refer to the following: Figure 2 , Figure 2The field of view (FOP) of the radar sensor is illustrated. The FOP of radar sensor 1 includes a desired sensing area 101 and a non-desired sensing area 102. The desired sensing area 101 further includes an alarm area 1011. Here, the FOP refers to the area covered by the field of view of radar sensor 1, the desired sensing area 101 refers to the area within the FOP of the radar sensor 1 that it intends to sense, and the non-desired sensing area 102 refers to the area within the FOP of the radar sensor 1 that it does not intend to sense. The alarm area 1011 is a specific area within the desired sensing area 101. When a target object enters the alarm area 1011 and the target object is a person, radar sensor 1 will not only sense the target object but also issue an alarm or record the target object (e.g., record the person's movement trajectory). In this embodiment, the alarm area 1011 can be set at any other location within the desired sensing area 101 as needed. For example, assuming the desired sensing area 101 is an office area, the alarm area 1011 can be set at the entrance / exit of the office area. Understandably, the entrances and exits of the office area are the main passageways for people to enter and exit. Setting alarm zone 1011 at the entrances and exits of the office area can ensure that any behavior of entering or leaving the office area can be detected immediately and accurately. This helps to more accurately detect and indicate the entry of personnel.

[0050] Please refer to the following: Figure 3 , Figure 3 This is a schematic diagram of the radar sensor 1. The radar sensor 1 includes a setting unit 11, a monitoring unit 12, and a processing unit 13. The setting unit 11 is used to set the desired sensing area 101 according to the setting information. The monitoring unit 12 is used to activate the radar sensor 1 to obtain sensing data within the field of view area 10. The processing unit 13 is used to filter the sensing data within the desired sensing area 101 from the sensing data within the field of view area 10, and to sense the target object within the desired sensing area 101 according to the sensing data. The setting unit 11 can obtain the setting information from any platform, such as a hardware platform, a software platform, or a cloud service platform. In this embodiment, the setting information of the setting unit 11 comes from the interactive platform 2, which is a software platform. The interactive platform 2 can be installed on any electronic device such as a computer or mobile device, and is not limited here.

[0051] Please refer to the following: Figure 4 , Figure 4This is a schematic diagram of the interactive platform 2. The interactive platform 2 includes several units, including but not limited to a boundary area setting unit 22, an intrusion area setting unit 23, and a field of view setting unit 24. Furthermore, the interactive platform 2 provides a radar chart 213, which is divided into several blocks. These blocks can be any of the boundary area 2131, intrusion area 21311, and invalid area 2132. The setting information for the boundary area 2131, intrusion area 21311, and invalid area 2132 respectively includes the spatial location information of the desired sensing area 101, the alarm area 1011, and the undesired sensing area 102. Understandably, the boundary area setting unit 22, the intrusion area setting unit 23, and the field of view setting unit 24 are respectively used to set the boundary area 2131, the intrusion area 21311, and the invalid area 2132 in the radar chart 213, and send the setting information of the boundary area 2131, the intrusion area 21311, and the invalid area 2132 to the radar sensor 1, and then set the desired sensing area 101, the alarm area 1011, and the undesired sensing area 102 of the radar sensor 1 based on the setting information of the boundary area 2131, the intrusion area 21311, and the invalid area 2132.

[0052] Please refer to the following: Figure 5 , Figure 5 This is a schematic diagram of the cutting settings interface. In this embodiment, the interactive platform 2 provides a cutting settings interface 21 and a parameter settings interface 22. The cutting settings interface 21 includes a boundary area setting interface 211 and an intrusion area setting interface 212. That is, this embodiment supports the functions corresponding to the boundary area setting unit, intrusion area setting unit 23, and field of view setting unit 24 at the software level by setting the boundary area setting interface 211, intrusion area setting interface 212, and parameter settings interface 22 at the physical level. Specifically, the parameter settings interface 22 is used to configure the field of view area 10 in response to user operations. The boundary area setting interface 211 and the intrusion area setting interface 212 are switched by the setting boundary button 2111 and the setting intrusion area button 2121, respectively. Among them, the boundary area setting interface 211 is used to configure the desired sensing area 101 and the undesired sensing area 102 in response to user operations, and the intrusion area setting interface 212 is used to configure the alarm area 1011 in response to user operations.

[0053] In this embodiment, the cutting settings interface 21 further includes a loading trajectory button 214, a generating boundary button 215, a confirming boundary button 216, a save backup button 217, a get backup button 218, and an enable intrusion button 219. Specifically, the loading trajectory button 214 is used to map the motion trajectory of the target object currently detected by the radar sensor 1 onto the radar image 213. The generating boundary button 215 is used to automatically generate a cutting boundary based on the motion trajectory of the target object currently mapped onto the radar image 213, thereby setting the boundary area 2131. The confirming boundary button 216 is used to set the desired sensing area 101 based on the setting information of the boundary area 2131. The enable intrusion button 219 is used to set the alarm area 101 based on the setting information of the intrusion area 21311. The save backup button 217 is used to upload the current setting information of the boundary area 2131 to the server 3 to save the setting information of the boundary area 2131. The backup button 218 is used to retrieve the previously saved setting information of the boundary area 2131 from the server 3 and map the setting information of the boundary area 2131 onto the radar chart 213.

[0054] Please refer to the following: Figure 6 , Figure 6 This is a schematic diagram of the parameter setting interface. In this embodiment, the parameter setting interface 22 includes, but is not limited to, the settings for maximum detection range, minimum detection range, maximum detection angle, and minimum detection angle. The parameter setting interface 22 also includes a parameter acquisition button 221, a parameter synchronization button 222, and a parameter modification button 223. The parameter acquisition button 221 is used to acquire relevant radar parameters of the radar sensor 1 (i.e., the aforementioned maximum detection range, minimum detection range, maximum detection angle, and minimum detection angle) and map these parameters onto the interactive platform 2. The parameter modification button 223 is used to save the modifications to the relevant radar parameters on the interactive platform 2. The parameter synchronization button 222 is used to synchronize the relevant radar parameters on the interactive platform 2 to the radar sensor 1 currently connected to the interactive platform 2.

[0055] Please refer to the following: Figure 7 , Figure 7 The flowchart illustrates the region identification method for a radar sensor provided in the first embodiment of this application. The region identification method includes steps S20-S60.

[0056] Step S20: The desired sensing area of ​​the radar sensor is set according to the setting information. Specifically, the setting information includes the spatial location information of the desired sensing area 101, and the setting unit 11 sets the desired sensing area 101 of the radar sensor 1 according to the spatial location information of the desired sensing area 101. The area 10 covered by the field of view of the radar sensor 1 includes not only the desired sensing area 101 but also the undesired sensing area 102. It can be understood that the desired sensing area 101 and the undesired sensing area 102 are complementary, both covering the field of view area 10 without overlapping. That is to say, when the desired sensing area 101 of the radar sensor 1 is determined, the undesired sensing area 102 of the radar sensor 1 is also determined accordingly.

[0057] Step S40: Activate the radar sensor to obtain sensing data within the field of view. Specifically, the monitoring unit 12 controls the radar sensor 1 to activate and transmit radar signals to the field of view region 10. The monitoring unit 12 receives the reflected echo signals and obtains point cloud data based on the echo signals. This point cloud data is the sensing data within the field of view region 10.

[0058] Step S60 involves acquiring sensing data within the desired sensing area and sensing target objects within the desired sensing area based on the sensing data. Specifically, after the radar sensor 1 receives sensing data (i.e., point cloud data) within the field of view region 10, the processing unit 13 filters and processes the point cloud data based on its spatial location information. Point cloud data whose spatial location information belongs to the desired sensing area 101 is retained, while point cloud data whose spatial location information belongs to a non-desired sensing area 102 is discarded, thereby extracting the sensing data within the desired sensing area 101. In other words, the radar sensor 1 does not directly process the sensing data within the field of view region 10, but only processes the sensing data within the desired sensing area 101. Therefore, this application not only reduces the data processing load of the radar sensor 1 but also avoids interference from sensing data in a non-desired sensing area 102, resulting in more accurate sensing results.

[0059] In the above embodiment, the radar sensor 1 predetermines its desired sensing area 101 based on the set information. At the same time, the radar sensor 1 only acquires sensing data within the desired sensing area 101, so as to realize that it only senses target objects within the pre-set desired sensing area 101, thereby improving the sensing accuracy of the radar sensor 1.

[0060] Please refer to the following: Figure 8 , Figure 8The flowchart illustrates the area identification method for a radar sensor provided in the second embodiment of this application. The difference between the second embodiment and the first embodiment is that the second embodiment configures the setting information through the interactive platform 2, and the second embodiment has an additional step S10 compared to the first embodiment.

[0061] In step S10, the interactive platform responds to the user's operation settings and sends the setting information to the radar sensor. In this embodiment, step S10 includes two optional methods for configuring the setting information. One is to configure the setting information based on the motion trajectory of the target object, and the other is to configure the setting information manually by the user. It can be understood that this embodiment can configure the setting information based solely on the motion trajectory of the target object, or it can be configured solely by the user manually. In addition, it is also possible to configure the setting information based on the motion trajectory of the target object and then adjust the setting information manually by the user, which is not limited here.

[0062] Please refer to the following: Figure 9 , Figure 9 The diagram illustrates the first sub-process of the area identification method for a radar sensor provided in the second embodiment of this application. The configuration of the setting information based on the motion trajectory of the target object includes steps S101-S105.

[0063] In step S101, the interactive platform responds to the user's operation by acquiring the motion trajectory of the target object within the field of view and mapping the motion trajectory onto the radar chart. Specifically, in the cutting settings interface 21, the user clicks the load trajectory button 214, so that the interactive platform 2 responds to the user's operation by acquiring the motion trajectory of the target object within the field of view region 10 and mapping the motion trajectory onto the radar chart 213.

[0064] In step S103, the interactive platform responds to the user's operation by automatically generating cutting boundaries on the radar image based on the motion trajectory, thereby setting boundary areas and invalid areas. The cutting boundaries enclose the boundary areas, and the invalid areas are the blocks on the radar image excluding the boundary areas. Specifically, in the cutting settings interface 21, the user clicks the "Generate Boundary" button 215, causing the interactive platform 2 to automatically generate cutting boundaries on the radar image 213 based on the acquired motion trajectory. These cutting boundaries enclose boundary 2131, thus setting the boundary area 2131. Understandably, the boundary area 2131 and the invalid area 2132 correspond to the desired sensing area 101 and the undesired sensing area 102, respectively. In other words, the boundary area 2131 and the invalid area 2132 are complementary; they both cover the radar image 213 but do not overlap. That is, once the boundary area 2131 is set, the range of the invalid area 2132 is also determined accordingly.

[0065] In step S105, the interactive platform responds to the user's operation by sending the setting information of the boundary area and invalid area to the radar sensor. Specifically, in the cutting setting interface 21, the user clicks the "Confirm Boundary" button 216, causing the interactive platform 2 to respond to the user's operation by sending the setting information of the boundary area 2131 and invalid area 2132 to the radar sensor 1, thereby enabling the radar sensor 1 to determine its desired sensing area 101 and undesired sensing area 102 based on the setting information of the boundary area 2131 and invalid area 2132.

[0066] Please refer to the following: Figure 10 , Figure 10 The second sub-process of the area identification method for a radar sensor provided in the second embodiment of this application is illustrated. This involves manually configuring the setting information by the user, including steps S107-S109.

[0067] In step S107, the interactive platform responds to the user's operation by switching each block from a boundary area to an invalid area or vice versa, thereby setting the boundary area and invalid area. In this embodiment, in the boundary area setting interface 211, the boundary area 2131 and the invalid area 2132 correspond to the light red block and the white block in the radar chart 213, respectively. The user can manually click on the light red block to switch the corresponding boundary area 2131 to the invalid area 2132, or manually click on the white block to switch the corresponding invalid area 2132 to the boundary area 2131, thereby setting the boundary area 2131 and invalid area 2132 in the radar chart 213.

[0068] In step S109, the interactive platform responds to the user's operation by sending the setting information of the boundary area and invalid area to the radar sensor. Specifically, in the cutting setting interface 21, the user clicks the "Confirm Boundary" button 216, causing the interactive platform 2 to respond to the user's operation by sending the setting information of the boundary area 2131 and invalid area 2132 to the radar sensor 1, thereby enabling the radar sensor 1 to determine its desired sensing area 101 and undesired sensing area 102 based on the setting information of the boundary area 2131 and invalid area 2132.

[0069] Optionally, the area identification method of the radar sensor further includes setting an alarm zone 1011 for the radar sensor 1. The interactive platform 2 responds to user operations by switching each block from the intrusion zone 21311 to the boundary zone 2131 or vice versa, thus setting the intrusion zone 21311. The interactive platform responds to user operations by setting the alarm zone of the radar sensor according to the intrusion zone setting information, so that when a target object enters the alarm zone, the radar sensor is triggered to issue an alarm or record. In this embodiment, the intrusion zone 21311 corresponds to the light yellow block in the radar chart 213. In the cutting setting interface 21, the user can manually click the light yellow block to switch the corresponding boundary zone 2131 to the intrusion zone 21311, or click the light red block to switch the corresponding intrusion zone 21311 back to the boundary zone 2131. Furthermore, in some feasible embodiments, the boundary zone 2131, the intrusion zone 21311, and the invalid zone 2132 can also be set to other colored blocks, which is not limited here.

[0070] Optionally, the area identification method of the radar sensor also includes saving the boundary area setting information. Specifically, in the cutting settings interface 21, the user clicks the save backup button 217, so that the interactive platform 2 responds to the user's operation and uploads the current boundary area setting information to the server to save the boundary area setting information.

[0071] Optionally, the area identification method for radar sensors further includes acquiring boundary area setting information. Specifically, in the cutting settings interface 21, the user clicks the "Get Backup" button 218, causing the interactive platform 2 to respond to the user's operation by retrieving previously saved boundary area setting information from the server 3 and mapping the boundary area setting information onto the radar map 213 for the user to view or modify. In this embodiment, the server 3 stores boundary area setting information for different radar sensors 1. The server 3 acquires the boundary area setting information of the radar sensor 1 currently communicating with the interactive platform 2 based on the MAC address of that radar sensor 1.

[0072] Optionally, the area identification method for the radar sensor further includes setting the field of view region 10 of the radar sensor 1. Specifically, in the parameter setting interface 22, the user manually sets the radar parameters, including the maximum detection range, minimum detection range, maximum detection angle, and minimum detection angle. Then, the user clicks the "Modify Parameters" button 223, causing the interactive platform 2 to save the radar parameter settings in response to the user's operation. Finally, the user clicks the "Synchronize Parameters" button 222, causing the interactive platform 2 to set the field of view region 10 of the radar sensor 1 according to the radar parameter settings in response to the user's operation.

[0073] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.

[0074] The above-listed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
