[0001] The present application generally relates to the field of radar networking, and more specifically to a dynamic adjustment method and system for multi-radar networking. Background Art

[0002] With the rapid development of modern IoT devices, people are inseparable from these IoT devices in their lives. Radar, as a radio frequency sensor similar to infrared and ultrasonic sensors, plays a fundamental role in the detection entrance of IoT devices.

[0003] Most radar modules on the market are single-radar detection modules without networking functions. Even if there are a few radar modules equipped with networking functions, they mostly report their status to the gateway in a one-way manner, and do not further optimize the radar module in networking and communication with the gateway. Therefore, the radar module usually maintains the factory configuration during operation. This makes it impossible to adjust the configuration parameters of the radar module according to the on-site environment, resulting in uneven performance of the same radar module in complex environments.

[0014] The features and exemplary embodiments of various aspects of the application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the application. However, it is obvious to those skilled in the art that the application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the application by illustrating the example of the application. The application is by no means limited to any specific configuration proposed below, but covers any modification, replacement and improvement of elements, parts and algorithms without departing from the spirit of the application. In the accompanying drawings and the following description, known structures and technologies are not shown to avoid causing unnecessary ambiguity to the application.

[0015] Taking into account the deficiencies of the existing solutions mentioned in the above background technology, the present application proposes a dynamic adjustment method and system for multi-radar networking, which enables the configuration parameters of radar modules in the multi-radar networking to be dynamically adjusted according to the on-site environment, so as to better adapt to the application requirements of actual complex environments.

[0016] Figure 1 The structure of the radar module is shown in Figure 1. Figure 1 As shown, a conventional radar module usually consists of the following three parts: a radar chip, an algorithm chip, and a wireless chip. The radar chip is used to transmit and receive radar signals, and then provide corresponding electronic signals. The algorithm chip is used to collect the electronic signals output by the radar chip, and perform data processing and data analysis on the electronic signals through the built-in algorithm to determine the current detection status of the radar module, such as whether there is object movement, the movement speed of the object, etc. Then, the algorithm chip outputs the calculated results (for example, the current radar detection status information of the radar module) to the wireless chip. The wireless chip is used to communicate with the upper-level module or other wireless modules of the same level through electromagnetic wave wireless signals to transmit relevant information, such as the current radar detection status information of the radar module, the setting values ​​of the configuration parameters of the radar module, etc.

[0017] In actual environments, multiple radar modules are usually deployed, and these radar modules are communicatively coupled to a gateway server to form a multi-radar networking system. Figure 2 FIG. 2 shows an exemplary multi-radar networking system according to an embodiment of the present application. Figure 2 As shown, the gateway server is coupled to multiple radar modules via a wireless network. Each radar module can report its current radar detection status information and the current setting value of the configuration parameter to the gateway server. After the gateway server collects the information reported by each radar module, it can control and manage each radar module separately.

[0018] In addition, a more common radar module configuration method is to network the radar modules in the form of groups. For example, some radar modules can form a first radar group, and some other radars can form a second radar group. By analogy, a single radar module can also be grouped separately to form a multi-radar network including multiple radar groups, which is communicatively coupled to the gateway server. Figure 3 Another exemplary multi-radar networking system according to an embodiment of the present application is shown. Figure 3 As shown, radar module 1 to radar module n are networked in the form of groups, wherein radar module 1 and radar module n are grouped separately, radar module 2 to radar module 5 form radar group 1, radar module 6 and radar module 7 form radar group 2, and so on.

[0019] As described above, the present application proposes a method and system for dynamically adjusting a multi-radar network, so that the configuration parameters of the radar modules in the multi-radar network can be dynamically adjusted according to the on-site environment. Figure 2 or Figure 3 As shown. Specifically, the multi-radar networking system may include a gateway server and a multi-radar networking communicatively coupled to the gateway server, the multi-radar networking including one or more radar groups, each radar group including one or more radar modules. In the multi-radar networking system, each radar module in each radar group may dynamically report its current radar detection state information and current setting values ​​of configuration parameters to the gateway server, the gateway server may process the information received from each radar module, and re-update the online dynamic configuration of the radar module according to the on-site environment, so that the configuration parameters of the radar module can better adapt to the application requirements of the actual complex environment.

[0020] In the multi-radar networking system according to the present application, the gateway server can realize dynamic adjustment of the multi-radar networking by interacting with each radar module in each radar group, and more specifically, realize dynamic adjustment of the configuration parameters of the radar modules in the multi-radar networking.

[0021] Figure 4 FIG. 1 is a schematic flow chart of a method for dynamically adjusting a multi-radar network according to an embodiment of the present application. Figure 4As shown, the dynamic adjustment method of multi-radar networking may include operations 410 to 430. In operation 410, the gateway server may query and record the configuration parameters to be adjusted of each radar module in the radar group after the multi-radar networking grouping is completed. Specifically, after the radar modules in the multi-radar networking are grouped, the gateway server may query and record the configuration parameters to be adjusted of each radar module. According to an embodiment of the present application, the configuration parameters to be adjusted of the radar module may include any relevant configuration parameters of the radar module, for example, the trigger threshold of the radar module, the operating frequency point of the radar module, the control duration of the control signal output by the radar module, and the like. According to actual conditions, some configuration parameters of the radar module may be dynamically adjusted, so after the radar modules in the multi-radar networking are grouped, the gateway server may query and record the configuration parameters to be adjusted of the radar module. In addition, the gateway server may record the default setting values ​​of the configuration parameters to be adjusted of each radar module, so as to serve as a reference when the configuration parameters are dynamically adjusted later. In operation 420, the gateway server may determine one or more radar modules in the radar group that need to be adjusted for configuration parameters and corresponding configuration parameter adjustment values ​​based on the current radar detection state information dynamically reported by each radar module in the radar group and the current setting value of the configuration parameter to be adjusted when the multi-radar network is working in a field environment. Then, in operation 430, the gateway server may send a configuration parameter adjustment instruction to the determined one or more radar modules to control the one or more radar modules to dynamically adjust the configuration parameters based on the configuration parameter adjustment value.

[0022] The following will describe in more detail the dynamic adjustment method of multi-radar networking according to the exemplary embodiment of the present application, taking the trigger threshold of the radar module as an example of the configuration parameter to be adjusted.

[0023] Usually, each radar module has a built-in trigger threshold when calculating in the algorithm chip. When the result obtained after the electronic signal of the radar chip is processed by the algorithm chip is greater than this trigger threshold, the radar module will be triggered to perform radar detection, such as determining whether there is an object in motion. Since this trigger threshold is usually set by default before the radar module leaves the factory and cannot be modified by the user, the detection distance of the radar module when working in an actual complex environment is sometimes far and sometimes near. Or, in some cases, people have also thought of modifying the trigger threshold of the radar module according to the actual working environment, but most of them require the radar module to be removed from the actual product (such as a sensor lamp, a sensor module), and then the trigger threshold of the radar module is modified. Such modification operations are very unfriendly, and it seems incapable of adjusting the configuration parameters of a large number of radar modules.

[0024] According to an exemplary embodiment of the present application, a dynamic adjustment method for a multi-radar network is proposed, which can dynamically adjust the trigger thresholds of radar modules in radar groups in the multi-radar network according to the on-site environment of the multi-radar network. Figure 5 FIG. 1 is a schematic flow chart of an exemplary dynamic adjustment method for multiple radar networks according to an embodiment of the present application. Figure 5 As shown, the exemplary dynamic adjustment method of multi-radar networking includes operations 510 to 540. When the radar module leaves the factory, the trigger threshold of the radar module is usually randomly set within a range that meets the basic application scenario. For example, the trigger threshold can be set within the range of 5 to 10, and the corresponding radar detection distance is 5 to 10 meters. In an actual complex environment, when the environment area is large or the environment is complex, multiple radar modules need to be arranged. Multiple radar modules can be grouped according to area or scene, and each radar group can correspond to a simple scene with relatively balanced environmental variables. For example, in a complex hotel environment, the simple scene corresponding to the radar group can be a corridor, a banquet hall, a room, and so on. In this way, a complex environment can be converted into a collection of simple scenes with relatively balanced environmental variables through grouping.

[0025] After the radar modules are grouped, the gateway server may query and record the default trigger thresholds of the radar modules one by one, as shown in operation 510. When the multi-radar network is working in a field environment, the radar modules in each radar group will dynamically report their current radar detection status information and trigger thresholds to the gateway server. After the multi-radar network is configured in a field working environment, each radar group corresponds to a simple scene with relatively balanced environmental variables. When an object moves in the scene, since the trigger threshold configurations of the radar modules in the radar group may be inconsistent, even in the same scene, some radar modules are triggered while others are not.

[0026] In operation 520, the gateway server may receive the current radar detection state information and trigger threshold dynamically reported by the radar module in each radar group. In operation 530, when the current radar detection state information dynamically reported by the radar module in the radar group indicates that the radar module is not triggered, the gateway server may determine that the radar module is a radar module that needs to be adjusted for configuration parameters, and determine the trigger threshold adjustment value of the radar module. In operation 540, the gateway server may send a configuration parameter adjustment instruction to the radar module that has not been triggered in the radar group to control the radar module to adjust its trigger threshold to be closer to the trigger threshold of the triggered radar module based on the trigger threshold adjustment value.

[0027] For example, a radar group may include five radar modules: radar module 1 to radar module 5, and the default trigger thresholds of these radar modules are 5, 6, 7, 8, and 9, respectively. When the multi-radar network is working in a field environment, if the gateway server determines that radar module 1 to radar module 3 are triggered and radar module 4 and radar module 5 are not triggered based on the detection status information reported by these radar modules, the gateway server may send a configuration parameter adjustment instruction to radar module 4 and radar module 5 to control radar module 4 and radar module 5 to adjust their trigger thresholds so that their trigger thresholds are close to the trigger thresholds of radar module 1 to radar module 3. For example, radar module 4 and radar module 5 may respectively reduce their trigger thresholds by 1, so that the trigger thresholds of radar module 1 to radar module 5 are adjusted to 5, 6, 7, 7, and 8.

[0028] Furthermore, the gateway server may repeatedly perform operations 520 to 540 to dynamically adjust the trigger threshold of each radar module in each radar group in the multi-radar network, so that after multiple adjustments, the trigger threshold of each radar module in a radar group reaches a similar value. Note that the optimal trigger thresholds of these radar modules may be slightly different, because in an actual environment, even for two similar radar modules, their optimal trigger thresholds may be different due to factors such as installation distance, installation direction, and wall reflection.

[0029] According to Figure 5 The dynamic adjustment method of the multi-radar network shown in the invention dynamically adjusts the radar modules in one or more radar groups in the multi-radar network multiple times through the gateway server, so that the trigger thresholds of these radar modules arranged in the actual working environment can be dynamically adjusted adaptively according to the current actual working environment, thereby achieving the optimal trigger threshold suitable for the actual working environment.

[0030] In summary, the embodiments of the present application disclose a multi-radar networking system and a dynamic adjustment method of the multi-radar networking applied to the system, so that the configuration parameters of the radar modules in the multi-radar networking can be dynamically adjusted according to the actual working environment to better adapt to the application requirements of the actual complex environment.
