Description

Technical Field

[0001] The present invention relates to the field of radar technology, and in particular to an adaptive anti-interference method and device based on radar equipment. Background Art

[0002] In existing technologies, microwave / millimeter-wave radar sensors primarily detect human activity using the Doppler principle or frequency-modulated continuous wave (FMCW) technology. The underlying principle is that the RF signal emitted by the radar reaches the radar's receiver via direct or reflected radiation. However, in real-world situations, if more than one radar sensor is installed in a nearby area, interference between them will occur. This manifests as the appearance of false moving objects after prolonged operation, leading to deviations in radar sensor detection results or even false detection errors. Therefore, it is crucial to provide a new anti-interference method to address the problem of mutual interference between multiple radar devices. Summary of the Invention

[0065] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0066] The terms "first," "second," and so on, in the description and claims of the present invention and the accompanying drawings are used to distinguish between different items, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product, or end comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed therein, or may optionally include other steps or elements inherent to such process, method, product, or end.

[0067] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0068] The present invention discloses an adaptive anti-interference method and apparatus based on radar equipment. These methods can reduce signal interference between multiple radar devices, thereby improving radar detection accuracy and stability during spatial scanning. These methods are described in detail below.

[0069] In order to better understand the adaptive anti-interference method and device based on radar equipment disclosed in the present invention, the scenario of adaptive anti-interference based on radar equipment is first described. Specifically, the scenario of adaptive anti-interference based on radar equipment can be as follows: Figure 1 As shown, Figure 1 FIG. 1 is a schematic diagram of a scenario of adaptive anti-interference based on radar equipment disclosed in an embodiment of the present invention. Figure 1 As shown, the radar device-based adaptive anti-interference scenario may include a gateway and radar sub-devices. There are at least two radar sub-devices, and each radar sub-device corresponds to a signal coverage area of ​​the radar sub-device. The signal coverage areas corresponding to different radar sub-devices may overlap. The radar device-based adaptive anti-interference scenario can be a home scenario, a shopping mall scenario, a company scenario, or a variety of other scenarios, which are not limited in the embodiments of the present invention. It should be noted that in the radar device-based adaptive anti-interference scenario, the device information of each radar device in the current area is obtained; based on the current operating frequency band of each radar device, the target radar device that needs to adjust the frequency band is determined, and the target frequency band number corresponding to each target radar device is determined; for each target radar device, the target frequency band number corresponding to the target radar device is sent to the target radar device, triggering the target radar device to adjust the frequency of the output signal according to the target frequency band number, so that the signal frequency output by each radar device in the current area is different. In this way, by changing the signal frequency output by each radar device, the problem of signal interference in the overlapping area between the radars can be prevented, and the interference of signals between the radar devices when there are multiple radar devices can be reduced, which is beneficial to improving the accuracy of radar device detection and improving the stability when using radar equipment for spatial scanning.

[0070] Optionally, based on the current operating frequency band of each radar device, determine whether there is a radar device with the same operating frequency band among all radar devices. If so, all radar devices with the same operating frequency band are determined as target radar devices that require frequency band adjustment.

[0071] Optionally, based on the device information of the radar devices existing in the current area, a first frequency band that meets the pre-set transmission conditions is determined from all frequency bands, and based on the spatial scanning type of each radar device, the spatial scanning frequency band corresponding to the radar device is determined, and the spatial scanning frequency band corresponding to all radar devices is determined as the second frequency band of the current area, and the resource occupancy coefficients of the first frequency band and the second frequency band are further determined. For each target radar device, based on the resource occupancy coefficient and the pre-set resource threshold, a target frequency band number that matches the target radar device is determined as the target frequency band number corresponding to each target radar device.

[0072] Further optionally, for each target radar device, the coverage area of ​​the target radar device is determined based on the current operating frequency band of the target radar device, the overlapping area is determined based on the coverage areas of all target radar devices, and the target radar device corresponding to each overlapping area is determined. For each overlapping area, the target frequency band number of each target radar device corresponding to the overlapping area is determined based on the target radar device corresponding to the overlapping area and the device information of each target radar device corresponding to the overlapping area.

[0073] For example, the gateway obtains the device information of each radar sub-device in the current scene through a data statistics method, where the device information may include one or more of the identity identification information, online status information, and type quantity statistics information of each radar sub-device; the gateway determines the frequency band number with relatively loose frequency resources from all frequency bands based on the device information of each radar sub-device obtained by the data statistics method through a dynamic allocation method, where the frequency band number with relatively loose frequency resources is the frequency band number with a smaller number of online sensors; furthermore, the gateway realizes spatial scanning between the gateway and each radar sub-device through an information notification method, and each radar sub-device realizes frequency control of its output signal through a frequency resource management method, so that the signals in the overlapping areas between each radar sub-device are not interfered with.

[0074] It should be noted that Figure 1 The scenario architecture shown is only for the purpose of illustrating the use of the radar-based adaptive anti-interference method. The gateway, radar sub-devices, coverage areas, and overlapping areas involved are only schematic. The specific structure, size, shape, location, and installation method can be adjusted adaptively according to the actual scenario. Figure 1 The scenario architecture shown is not limited to this.

[0075] The above describes the application scenarios of the adaptive anti-interference method based on radar equipment. The following describes the adaptive anti-interference method and device based on radar equipment in detail.

[0076] Example 1

[0077] See also Figure 2 , Figure 2 This is a flow chart of an adaptive anti-interference method based on radar equipment disclosed in an embodiment of the present invention. Figure 2 The adaptive anti-interference method based on radar equipment described can be applied to an adaptive anti-interference device based on radar equipment, and can also be applied to a cloud server or a local server based on adaptive anti-interference of radar equipment, and the embodiment of the present invention does not limit it. Figure 2 As shown, the adaptive anti-interference method based on radar equipment may include the following operations:

[0078] 201. Obtain device information of each radar device in the current area.

[0079] In the embodiment of the present invention, the number of radar devices is at least two, and the device information includes the current operating frequency band of each radar device.

[0080] In an embodiment of the present invention, optionally, obtaining the device information of each radar device in the current area may be obtained in real time or may be obtained periodically according to a pre-set time period, which is not limited in the embodiment of the present invention.

[0081] In the embodiment of the present invention, optionally, the current area is the coverage area corresponding to all radar devices. Further optionally, the current area can be the coverage area corresponding to the radar device to be adaptively adjusted for anti-interference.

[0082] 202. Determine, based on the current operating frequency band of each radar device, a target radar device that requires frequency band adjustment, and determine a target frequency band number corresponding to each target radar device.

[0083] In the embodiment of the present invention, optionally, determining the target radar device requiring frequency band adjustment based on the current operating frequency band of each radar device may include:

[0084] Based on the current operating frequency band of each radar device, determine whether there is a radar device with the same current operating frequency band. If so, determine the coverage area corresponding to each radar device with the same current operating frequency band. Determine whether there is an overlapping area among the coverage areas corresponding to each radar device with the same current operating frequency band. If so, determine the radar device corresponding to the overlapping area as the target radar device that needs to adjust the frequency band.

[0085] 203. For each target radar device, send the target frequency band number corresponding to the target radar device to the target radar device to trigger the target radar device to adjust the frequency of the output signal according to the target frequency band number, so that the signal frequency output by each radar device in the current area is different.

[0086] In the embodiment of the present invention, optionally, the target frequency band number corresponding to each target radar device may be a different frequency band number.

[0087] In the embodiment of the present invention, optionally, after sending, for each target radar device, a target frequency band number corresponding to the target radar device to the target radar device to trigger the target radar device to adjust the frequency of the output signal according to the target frequency band number, so that the signal frequency output by each radar device in the current area is different, the method may further include:

[0088] Detect whether the number of radar devices in the current area increases;

[0089] When an increase in the number of radar devices in the current area is detected, the frequency band number of the added radar device and the coverage area corresponding to the radar device are obtained, and whether the radar device interferes with the output signals of other radar devices in the current area;

[0090] When it is determined that the radar device interferes with the output signals of other radar devices in the current area, re-triggering the operation of determining, based on the current operating frequency band of each radar device, target radar devices requiring frequency band adjustment, and determining the target frequency band number corresponding to each target radar device; for each target radar device, sending the target frequency band number corresponding to the target radar device to the target radar device to trigger the target radar device to adjust the frequency of the output signal according to the target frequency band number, so that the signal frequencies output by each radar device in the current area are different;

[0091] When it is determined that the radar device does not interfere with the output signals of other radar devices in the current area, this process can be terminated.

[0092] It can be seen that implementation Figure 2 The described radar device-based adaptive anti-interference method can obtain device information of each radar device in the current area; determine the target radar device that needs to adjust the frequency band according to the current operating frequency band of each radar device, and determine the target frequency band number corresponding to each target radar device; for each target radar device, the target frequency band number corresponding to the target radar device is sent to the target radar device to trigger the target radar device to adjust the frequency of the output signal according to the target frequency band number, so that the signal frequency output by each radar device in the current area is different, which can reduce the interference of signals between the radar devices when there are multiple radar devices, is conducive to improving the accuracy of radar device detection, and is conducive to improving the stability when using radar devices for spatial scanning.

[0093] Example 2

[0094] See also Figure 3 , Figure 3 This is a flow chart of an adaptive anti-interference method based on radar equipment disclosed in an embodiment of the present invention. Figure 3 The adaptive anti-interference method based on radar equipment described can be applied to an adaptive anti-interference device based on radar equipment, and can also be applied to a cloud server or a local server based on adaptive anti-interference of radar equipment, and the embodiment of the present invention does not limit it. Figure 2 As shown, the adaptive anti-interference method based on radar equipment may include the following operations:

[0095] 301. Obtain device information of each radar device in the current area.

[0096] 302. Determine, based on the current operating frequency band of each radar device, whether there is a radar device with the same operating frequency band among all radar devices.

[0097] In an embodiment of the present invention, when it is determined that a radar device with the same operating frequency band exists among all radar devices, step 303 is triggered to be executed; when it is determined that no radar device with the same operating frequency band exists among all radar devices, this process can be terminated.

[0098] In the embodiment of the present invention, for example, if there are two radar devices in the current area and both currently operate in a frequency band of 10.0 to 10.2 GHz, the two radar devices are determined to be radar devices with the same operating frequency band.

[0099] 303. When it is determined that there are radar devices with the same operating frequency band among all the radar devices, all the radar devices with the same operating frequency band are determined as target radar devices that require frequency band adjustment, and a target frequency band number corresponding to each target radar device is determined.

[0100] In the embodiment of the present invention, further optionally, the method may further include:

[0101] When it is determined that there are radar devices with the same operating frequency band among all the radar devices, the radar devices with the same operating frequency band are determined as a radar device set;

[0102] For each radar device set, determine the coverage range corresponding to each radar device in the radar device set, and judge whether there is an overlapping area based on the coverage range corresponding to each radar device. If there is an overlapping area, determine the radar device corresponding to the overlapping area as the target radar device that requires frequency band adjustment. If there is no overlapping area, determine that there is no target radar device in the radar device set that requires frequency band adjustment.

[0103] In this way, it is possible to determine whether there is an overlapping area based on the coverage area corresponding to each radar device. If there is no overlapping area, there is no need to adjust the working frequency band of the radar device, which can improve the efficiency of adjusting the working frequency band of the radar device, thereby improving the efficiency of the radar device's adaptive anti-interference, and further helping to improve the intelligence of the radar device's adaptive anti-interference.

[0104] 304. For each target radar device, send the target frequency band number corresponding to the target radar device to the target radar device to trigger the target radar device to adjust the frequency of the output signal according to the target frequency band number, so that the signal frequency output by each radar device in the current area is different.

[0105] In the embodiment of the present invention, for other descriptions of step 301 and step 304, please refer to the detailed description of step 201 and step 203 in the first embodiment, which will not be repeated in the embodiment of the present invention.

[0106] It can be seen that implementation Figure 3 The described radar device-based adaptive anti-interference method can obtain device information of each radar device in the current area, and determine whether there is a radar device with the same operating frequency band among all radar devices based on the current operating frequency band of each radar device. If so, all radar devices with the same operating frequency band are determined as target radar devices that require frequency band adjustment, and the target frequency band number corresponding to each target radar device is determined. For each target radar device, the target frequency band number corresponding to the target radar device is sent to the target radar device to trigger the target radar device to adjust the frequency of the output signal according to the target frequency band number, so that the signal frequency output by each radar device in the current area is different. This can reduce signal interference between the radar devices when there are multiple radar devices, which is beneficial to improving the accuracy of radar device detection and the stability when using radar devices for spatial scanning.

[0107] In an optional embodiment, determining the target frequency band number corresponding to each target radar device includes:

[0109] Based on the first frequency band and the second frequency band, a target frequency band number corresponding to each target radar device in the current area is determined.

[0110] In this optional embodiment, the number of first frequency bands may be one or more; the number of second frequency bands may be one or more, which is not limited in the embodiment of the present invention.

[0111] In this optional embodiment, it should be noted that the first frequency band is a frequency band with a smaller number of online radar devices in a specific frequency band, that is, the idle communication resources in the first frequency band are greater than a preset resource threshold.

[0112] In this optional embodiment, determining the first frequency band and the second frequency band of the current area based on device information of radar devices existing in the current area may include:

[0113] Determine and analyze usage information of each radar device in the current area using a data statistical method, wherein the usage information of each radar device includes one or more of identity identification information, online status information, and type and quantity statistical information;

[0114] determining a first frequency band based on usage information of each radar device;

[0115] And, according to the usage information of each radar device and through a dynamic allocation method, the second frequency band corresponding to each radar device is determined.

[0116] It can be seen that the implementation of this optional embodiment can determine the first frequency band and the second frequency band of the current area based on the device information of the radar devices existing in the current area, and determine the target frequency band number corresponding to each target radar device in the current area based on the first frequency band and the second frequency band, which can improve the accuracy and reliability of determining the target frequency band number, thereby facilitating the improvement of the accuracy and reliability of anti-interference between radar devices, and further facilitating the improvement of the stability of spatial scanning of each radar device.

[0117] In another optional embodiment, determining the first frequency band and the second frequency band of the current area according to device information of radar devices existing in the current area includes:

[0118] Determine, based on device information of radar devices existing in the current area, a frequency band used by each radar device in the current area and frequency band resources corresponding to each frequency band used by each radar device;

[0119] Determining, from all frequency bands, a first frequency band that meets a preset transmission condition based on the frequency bands used by all radar devices and the frequency band resources corresponding to each frequency band used by all radar devices;

Based on the spatial scanning type of the radar device, the spatial scanning frequency band corresponding to the radar device is determined, and the spatial scanning frequency band corresponding to all radar devices is determined as the second frequency band of the current area.

[0121] In this optional embodiment, optionally, determining a first frequency band that meets a preset transmission condition from all frequency bands may include:

[0122] It is determined whether there is a frequency band in all frequency bands whose idle communication resources are greater than a preset resource threshold. If so, all frequency bands whose idle communication resources are greater than the preset resource threshold are determined as the first frequency band.

[0123] In this optional embodiment, for example, when the device information of the radar device is used to indicate that the radar device can only perform spatial scanning at a frequency of 9.8 to 10.0 GHz, the spatial scanning type of the radar device is determined to be a low-frequency transmission type, and 9.8 to 10.0 GHz is further determined as the transmission frequency band corresponding to the radar device, and 10.0 to 10.2 GHz is determined as the second frequency band of the current area.

[0124] It can be seen that implementing this optional embodiment can determine the frequency band used by each radar device in the current area and the frequency band resources corresponding to each frequency band used by each radar device based on the device information of the radar devices existing in the current area. According to the frequency bands used by all radar devices and the frequency band resources corresponding to each frequency band used by all radar devices, a first frequency band that meets the pre-set transmission conditions is determined from all frequency bands. Based on the device information of each radar device, the spatial scanning type of the radar device is determined, and the spatial scanning frequency band corresponding to the radar device is determined based on the spatial scanning type of the radar device. The spatial scanning frequency band corresponding to all radar devices is determined as the second frequency band. This can improve the accuracy and reliability of determining the first frequency band and the second frequency band, thereby improving the accuracy and reliability of anti-interference between radar devices, and further helping to improve the stability of spatial scanning of each radar device.

[0125] In yet another optional embodiment, determining a target frequency band number corresponding to each target radar device in the current area based on the first frequency band and the second frequency band includes:

[0126] Determining a first resource occupancy coefficient of the first frequency band and a second resource occupancy coefficient of the second frequency band;

[0127] For each target radar device, a target frequency band number that matches the target radar device is determined by using the first resource occupancy coefficient and the second resource occupancy coefficient in combination with a preset resource threshold, as the target frequency band number corresponding to each target radar device.

[0128] In this optional embodiment, the resource occupancy coefficient is optionally the number of times the frequency bands of the first radar and the Nth radar overlap. For example, if the frequency band of the first radar includes 9.8-10.0 GHz, and the frequency band of the second radar includes 9.8-10.0 GHz, then the resource occupancy coefficient of the 9.8-10.0 GHz frequency band is 2. Furthermore, the pre-set resource threshold may be a maximum available resource threshold. For example, if the pre-set resource threshold may be 6, and the resource occupancy coefficient of the 9.8-10.0 GHz frequency band is 2, then the 9.8-10.0 GHz frequency band may be determined as the target frequency band number corresponding to the target radar device.

[0129] It can be seen that implementing this optional embodiment can determine the resource occupancy coefficients of the first frequency band and the second frequency band. For each target radar device, the target frequency band number that matches the target radar device is determined by using the first resource occupancy coefficient and the second resource occupancy coefficient, in combination with a pre-set resource threshold, as the target frequency band number corresponding to each target radar device. This can also improve the accuracy and reliability of determining the target frequency band number, thereby improving the accuracy and reliability of anti-interference between radar devices, and further facilitating improving the stability of spatial scanning of each radar device.

[0132] Determine overlapping areas based on coverage areas of all target radar devices, and determine the target radar device corresponding to each overlapping area;

[0133] For each overlapping area, determining a target frequency band number of each target radar device corresponding to the overlapping area according to the target radar device corresponding to the overlapping area and the device information of each target radar device corresponding to the overlapping area;

[0134] The number of target radar devices corresponding to each overlapping area is at least two, and the frequency band numbers of the target radar devices corresponding to the same overlapping area are different.

[0135] In this optional embodiment, the number of overlapping regions may be one or more, which is not limited in the embodiment of the present invention. Further, when it is determined that no overlapping regions exist, it is determined that the operating frequency band of the radar device in the current region does not need to be adjusted, and the process may be terminated.

[0136] In this optional embodiment, the target radar devices corresponding to different overlapping regions may optionally have the same frequency band number. For example, if overlapping region A corresponds to radar device 1 and radar device 2, and overlapping region B corresponds to radar device 3 and radar device 4, radar device 1 and radar device 3 may have the same target frequency band number.

[0137] It can be seen that implementing this optional embodiment can determine the coverage area of ​​each target radar device, determine the overlapping area based on the coverage areas of all target radar devices, and determine the target radar device corresponding to each overlapping area. For each overlapping area, based on the target radar device corresponding to the overlapping area and the device information of each target radar device corresponding to the overlapping area, the target frequency band number of each target radar device corresponding to the overlapping area is determined. This can improve the accuracy and reliability of determining the target frequency band number, thereby improving the accuracy and reliability of anti-interference between radar devices, and further facilitating improving the stability of spatial scanning of each radar device.

[0138] In yet another optional embodiment, the device information of the radar devices existing in the current area includes one or more of identity identification information corresponding to each radar device and usage information corresponding to each radar device;

[0139] Among them, the usage information corresponding to each radar device includes one or more of the online information corresponding to each radar device, the output signal type information corresponding to each radar device, and the output frequency band information corresponding to each radar device.

[0140] In this optional embodiment, the identity identification information corresponding to each radar device may optionally include one or more of the following: user information of the radar device, owner information of the radar device, identity authentication information of the radar device, and identity authority information of the radar device. Optionally, the usage information corresponding to each radar device may include one or more of the following: usage duration information of the radar device, number of usage times of the radar device, and resource usage information of the radar device.

[0141] In this optional embodiment, the online information corresponding to each radar device may optionally include one or more of the following: online duration information of the radar device and information about online resource usage of the radar device. Optionally, the output frequency band type information corresponding to each radar device includes output signal frequency information of the radar device.

[0142] It can be seen that the device information of the radar equipment existing in the current area includes one or more of the identity identification information corresponding to each radar equipment and the usage information corresponding to each radar equipment, which can improve the accuracy and reliability of determining the target radar equipment and determining the target frequency band number corresponding to each target radar equipment, thereby helping to improve the accuracy and reliability of anti-interference between radar equipment, and further helping to improve the stability of spatial scanning of each radar equipment.

If so, all radar devices with the same operating frequency band are determined as target radar devices that require frequency band adjustment, and the target frequency band number corresponding to each target radar device is determined. For each target radar device, the target frequency band number corresponding to the target radar device is sent to the target radar device to trigger the target radar device to adjust the frequency of the output signal according to the target frequency band number, so that the signal frequency output by each radar device in the current area is different. This can reduce signal interference between the radar devices when there are multiple radar devices, which is beneficial to improving the accuracy of radar device detection and the stability when using radar devices for spatial scanning.
