[0058] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0059] The target perception method provided by the embodiments of the present application can be applied in an application environment as shown in Figure 1 . Among them, the target base station 102 communicates with the server 104 through the network. The data storage system can store the data required to be processed by the server 104. The data storage system can be integrated on the server 104, or placed on the cloud or other network servers. According to the target position of the perception target, the perception region type corresponding to the perception target is determined; and according to the perception feature parameter of the perception target, the perception event level to which the perception target belongs is determined, and then, according to the perception region type and the perception event level, the energy-saving perception strategy suitable for the perception target is determined, so as to realize the perception of the perception target based on the energy-saving perception strategy. The server 104 can be realized by an independent server or a server cluster composed of multiple servers.

[0060] In an embodiment, as shown in Figure 2 , a target perception method is provided, which is taken as an example to illustrate the target base station 102 in Figure 1 , including the following steps:

[0061] S201, according to the target position of the perception target, the perception region type corresponding to the perception target is determined.

[0062] It should be noted that the region range corresponding to different candidate region types can be determined in advance, and then the awareness region type corresponding to the awareness target is determined according to the belonging relationship between the target position and the region range corresponding to different candidate region types.

[0063] In an embodiment of the present application, when it is necessary to determine the awareness region type corresponding to the awareness target according to the target position of the awareness target, the following content can be specifically included: determining the region range corresponding to each candidate region type; and taking the candidate region type whose region range contains the target position as the awareness region type corresponding to the awareness target.

[0064] The candidate region types include a core region, a warning region, and a far region. The awareness performance of the core region is high as a whole (false alarm rate, missing detection rate, position accuracy, etc.), and part of the awareness performance of the warning region and the far region is high (false alarm rate, missing detection rate, etc.).

[0065] Further, the region range corresponding to different candidate region types can be set or adjusted according to actual conditions, and each region range corresponding to different candidate region types is not limited herein.

[0066] As an example, if the region ranges of the core region, the warning region, and the far region are as shown in FIG. 8, the region ranges corresponding to different candidate region types are divided by different colors. Figure 3

[0067] S202, determining the awareness event level to which the awareness target belongs according to the awareness characteristic parameter of the awareness target.

[0068] The awareness characteristic parameter corresponds to the specific type of the awareness target, for example, in the case of a vehicle as the awareness target, the awareness characteristic parameter is the driving speed of the awareness target; in the case of a drone as the awareness target, the awareness characteristic parameter is the flight height of the awareness target; in summary, the specific parameter type of the awareness characteristic parameter is not limited in the present application, and the specific parameter type of the awareness characteristic parameter can be set or adjusted according to actual conditions.

[0069] It should be noted that the parameter range corresponding to each candidate event level can be determined in advance, and then the awareness event level to which the awareness target belongs is selected from each candidate event level according to the containing relationship between the awareness characteristic parameter of the awareness target and the parameter range corresponding to each candidate event level.

[0070] In an embodiment of the present application, when it is necessary to determine the awareness event level to which the awareness target belongs according to the awareness characteristic parameter of the awareness target, the following content can be included: determining the parameter range corresponding to each candidate event level; and taking the candidate event level whose parameter range contains the awareness characteristic parameter as the awareness event level to which the awareness target belongs. ​

[0071] The candidate event level includes an emergency event level, a regular event level and a delayable event level. The emergency event refers to a high-index requirement event, the regular event refers to a medium-index requirement event, and the delayable event refers to a low-index requirement event.

[0072] Taking a perceived target vehicle as an example, if the perceived target vehicle moves at a high speed and there is a risk of collision, it corresponds to an emergency event; if the perceived target vehicle moves at a constant speed, it corresponds to a regular event; and if the perceived target vehicle is stationary, it corresponds to a delayable event.

[0073] Further, the region range corresponding to different candidate region types can be set or adjusted according to actual conditions, and the region range corresponding to each different candidate region type is not limited herein.

[0074] S203, determining an energy-saving perception strategy suitable for the perceived target according to the perception region type and the perception event level.

[0075] The energy-saving perception strategy includes a first energy-saving strategy and a second energy-saving strategy. The number of perception beams transmitted by the target base station in a perception cycle under the condition of performing perception operation based on the first energy-saving strategy is less than the number of perception beams transmitted by the target base station in a perception cycle under a standard state. The number of perception beams transmitted by the target base station in a perception cycle under the condition of performing perception operation based on the second energy-saving strategy is less than the number of perception beams transmitted by the target base station in a perception cycle under the condition of performing perception operation based on the first energy-saving strategy.

[0076] S204, performing perception on the perceived target based on the energy-saving perception strategy.

[0077] It should be noted that if the target base station transmits 8 pulsed perception beams and 8 continuous perception beams in a perception cycle under a standard state, the target base station transmits 4 pulsed perception beams and 4 continuous perception beams in a perception cycle under the condition of performing perception operation based on the first energy-saving strategy, and the target base station transmits 2 pulsed perception beams and 2 continuous perception beams in a perception cycle under the condition of performing perception operation based on the second energy-saving strategy.

[0078] In an embodiment of the present application, if the communication frame structure of the target base station is DDDSU, where DDDSU represents Downlink-Downlink-Downlink-Special Uplink (Downlink-Downlink-Downlink-Special Uplink); as shown in Figure 4As shown, the S time slot ratio is 10:2:2. 24 sensing symbols are configured in the 3rd D time slot and S time slot as a sensing period. In the case that the target base station does not perform the energy saving sensing strategy, the first 16 of the 24 sensing symbols are used to transmit pulse waves (P waves), each P wave occupying 2 symbols; the last 8 symbols are used to transmit continuous waves (C waves), each C wave occupying 1 symbol. When the target base station senses the sensing target based on the first energy saving strategy, the P / C wave configuration in the sensing period is halved, i.e., only 4 P waves and 4 C waves are transmitted. When the target base station senses the sensing target based on the second energy saving strategy, the P / C wave configuration in the sensing period is further halved, i.e., only 2 P waves and 2 C waves are transmitted. When the off is performed, the P / C wave configuration in the sensing period needs to follow the continuous off criterion.

[0079] Further explanation, if the energy saving sensing strategy is triggered in the current sensing period, the P / C wave of the current sensing period will be configured in the last few symbols, such as Figure 4 the case that the target base station senses the sensing target based on the second energy saving strategy in FIG. 6; if the energy saving sensing strategy is triggered before the current sensing period, or at the beginning of the current sensing period, the P / C wave will be configured first, such as Figure 4 the case that the target base station senses the sensing target based on the first energy saving strategy in FIG. 5.

[0080] The above target sensing method determines the sensing area type corresponding to the sensing target according to the target position of the sensing target, determines the sensing event level to which the sensing target belongs according to the sensing feature parameter of the sensing target, and then determines the energy saving sensing strategy suitable for the sensing target according to the sensing area type and the sensing event level, so as to realize sensing the sensing target based on the energy saving sensing strategy. According to the above content, it can be known that the sensing area type corresponding to the sensing target and the sensing event level to which the sensing target belongs are determined in the process of target sensing. In this way, the energy saving sensing strategy suitable for the sensing target is determined, and then the sensing target is sensed based on the energy saving sensing strategy. Since the number of sensing beams transmitted by the target base station in one sensing period in the case of sensing operation based on the first energy saving strategy is less than the number of sensing beams transmitted by the target base station in one sensing period in the standard state, and the number of sensing beams transmitted by the target base station in one sensing period in the case of sensing operation based on the second energy saving strategy is less than the number of sensing beams transmitted by the target base station in one sensing period in the case of sensing operation based on the first energy saving strategy. Therefore, the number of sensing beams transmitted by the base station in the target sensing process using any one of the energy saving sensing strategies is always less than the number of sensing beams transmitted by the target base station in one sensing period in the standard state, so as to realize the energy saving operation of the target base station.

[0081] As shown in FIG. 5, Figure 5As shown, when it is needed to determine the energy-saving perception strategy adapted to the perception target according to the perception area type and the perception event level, the following can be included:

[0082] S501, acquire the mapping relationship between the candidate perception strategy and the candidate area type and the candidate event level.

[0083] In the mapping relationship, the candidate perception strategies corresponding to different candidate area types and candidate event levels are recorded.

[0084] It should be noted that the mapping relationship can be set or adjusted according to actual conditions, and the specific content of the mapping relationship is not limited here.

[0085] S502, select the energy-saving perception strategy adapted to the perception target from the candidate perception strategies according to the mapping relationship.

[0086] It should be noted that when it is needed to select the energy-saving perception strategy adapted to the perception target from the candidate perception strategies according to the mapping relationship, the following can be included: selecting the reference area type and the reference event level same as the perception area type and the perception event level from different candidate area types and candidate event levels; and taking the candidate perception strategy corresponding to the reference area type and the reference event level in the mapping relationship as the energy-saving perception strategy adapted to the perception target.

[0087] In an embodiment of the present application, the mapping relationship can be as shown in the following table:

[0088] Candidate region type Candidate event class Energy saving awareness policy Core region Emergency event No Core region Routine event First energy saving policy Core region Delayable event Second energy saving policy Warning region Emergency event First energy saving policy Warning region Routine event Second energy saving policy Far zone Any event Second energy saving policy

[0089] The above target perception method, by acquiring the mapping relationship between the candidate perception strategy and the candidate area type and the candidate event level, realizes selecting the energy-saving perception strategy adapted to the perception target from the candidate perception strategies according to the mapping relationship, guarantees flexible adjustment for the target base station perception state, and reduces the perception consumption of the target base station in the perception process.

[0090] In an embodiment, as shown, Figure 6 When it is needed to perceive the perception target, the following can be included:

[0091] S601, determine the area range corresponding to each candidate area type; wherein the candidate area type includes a core area, a pre-warning area and a far area.

[0092] S602, take the candidate area type whose area range contains the target position as the perception area type corresponding to the perception target.

[0093] S603, determine the parameter range corresponding to each candidate event level; wherein the candidate event level includes an emergency event level, a regular event level and a delayable event level.

[0094] S604, the candidate event level containing the parameter range of the perception feature parameter is taken as the perception event level to which the perception target belongs.

[0095] S605, obtain the mapping relationship between the candidate perception strategy and the candidate region type and the candidate event level, wherein the mapping relationship records the candidate perception strategy corresponding to different candidate region types and candidate event levels.

[0096] S606, select the reference region type and the reference event level same as the perception region type and the perception event level from different candidate region types and candidate event levels.

[0097] S607, the candidate perception strategy corresponding to the reference region type and the reference event level in the mapping relationship is taken as the energy-saving perception strategy adapted to the perception target.

[0098] S608, perceive the perception target based on the energy-saving perception strategy.

[0099] Wherein, the energy-saving perception strategy includes a first energy-saving strategy and a second energy-saving strategy, the number of perception beams transmitted by the target base station in a perception cycle under the condition of performing perception operation based on the first energy-saving strategy is less than the number of perception beams transmitted by the target base station in a perception cycle under the standard state; the number of perception beams transmitted by the target base station in a perception cycle under the condition of performing perception operation based on the second energy-saving strategy is less than the number of perception beams transmitted by the target base station in a perception cycle under the condition of performing perception operation based on the first energy-saving strategy.

[0100] The above target sensing method determines the sensing area type corresponding to the sensing target according to the target position of the sensing target, and determines the sensing event level to which the sensing target belongs according to the sensing feature parameter of the sensing target, and then determines the energy-saving sensing strategy adapted to the sensing target according to the sensing area type and the sensing event level, and realizes sensing of the sensing target based on the energy-saving sensing strategy. According to the above content, it can be known that in the process of target sensing, the sensing area type corresponding to the sensing target and the sensing event level to which the sensing target belongs are determined in advance. In this way, the energy-saving sensing strategy adapted to the sensing target is determined in a targeted manner, and then the sensing target is sensed based on the energy-saving sensing strategy. Since the number of sensing beams transmitted by the target base station in a sensing period under the first energy-saving strategy is less than the number of sensing beams transmitted by the target base station in a sensing period under a standard state, and the number of sensing beams transmitted by the target base station in a sensing period under the second energy-saving strategy is less than the number of sensing beams transmitted by the target base station in a sensing period under the first energy-saving strategy. Therefore, the number of sensing beams transmitted by the base station when using any one of the energy-saving sensing strategies for target sensing is always less than the number of sensing beams transmitted by the target base station in a sensing period under the standard state, so as to realize energy-saving operation of the target base station.

[0102] Based on the same inventive concept, the embodiments of the present application also provide a target sensing device for implementing the above-mentioned target sensing method. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme described in the above method, so the specific limitations in one or more target sensing device embodiments provided below can refer to the limitations of the target sensing method in the above text, which will not be repeated here.

[0103] In one embodiment, as Figure 7As shown, a target perception device is provided, comprising: a first determination module 10, a second determination module 20, a third determination module 30 and a perception module 40, wherein:

[0104] The first determination module 10 is configured to determine a perception area type corresponding to the perception target according to a target position of the perception target.

[0108] The energy-saving perception strategy comprises a first energy-saving strategy and a second energy-saving strategy, and the number of perception beams transmitted by the target base station in a perception cycle under the condition of performing a perception operation based on the first energy-saving strategy is less than the number of perception beams transmitted by the target base station in a perception cycle under a standard state; the number of perception beams transmitted by the target base station in a perception cycle under the condition of performing a perception operation based on the second energy-saving strategy is less than the number of perception beams transmitted by the target base station in a perception cycle under the condition of performing a perception operation based on the first energy-saving strategy.

[0109] In an embodiment, a mapping relationship between a candidate perception strategy and a candidate area type and a candidate event level is obtained, wherein the mapping relationship records the candidate perception strategies corresponding to different candidate area types and candidate event levels;

[0110] According to the mapping relationship, an energy-saving perception strategy adapted to the perception target is selected from the candidate perception strategies.

[0111] In an embodiment, a reference area type and a reference event level same as the perception area type and the perception event level are selected from different candidate area types and candidate event levels;

[0112] The candidate perception strategy corresponding to the reference area type and the reference event level in the mapping relationship is taken as the energy-saving perception strategy adapted to the perception target.

[0113] In an embodiment, the area ranges corresponding to the candidate area types are determined; wherein the candidate area types comprise a core area, a pre-warning area and a far area;

[0114] The candidate area type whose area range contains the target position is taken as the perception area type corresponding to the perception target.

[0115] In an embodiment, a parameter range corresponding to each candidate event level is determined; wherein the candidate event level includes an emergency event level, a regular event level and a delayable event level;

[0116] The candidate event level containing the parameter range of the perception characteristic parameter is taken as the perception event level to which the perception target belongs.

[0117] In an embodiment, if the target base station transmits 8 pulsed perception beams and 8 continuous perception beams in one perception cycle in a standard state, the target base station transmits 4 pulsed perception beams and 4 continuous perception beams in one perception cycle in the case of performing the perception operation based on the first energy-saving strategy, and the target base station transmits 2 pulsed perception beams and 2 continuous perception beams in one perception cycle in the case of performing the perception operation based on the second energy-saving strategy.

[0118] The target perception device determines the perception region type corresponding to the perception target according to the target position of the perception target, determines the perception event level to which the perception target belongs according to the perception characteristic parameter of the perception target, and then determines the energy-saving perception strategy adapted to the perception target according to the perception region type and the perception event level, so as to perform the perception on the perception target based on the energy-saving perception strategy. According to the above content, it can be known that the perception region type corresponding to the perception target and the perception event level to which the perception target belongs are determined in the process of performing the target perception. In this way, the energy-saving perception strategy adapted to the perception target is determined in a targeted manner, and then the perception on the perception target is performed based on the energy-saving perception strategy. Since the number of perception beams transmitted by the target base station in one perception cycle in the case of performing the perception operation based on the first energy-saving strategy is less than the number of perception beams transmitted by the target base station in one perception cycle in a standard state, and the number of perception beams transmitted by the target base station in one perception cycle in the case of performing the perception operation based on the second energy-saving strategy is less than the number of perception beams transmitted by the target base station in one perception cycle in the case of performing the perception operation based on the first energy-saving strategy, the number of perception beams transmitted by the base station in the process of performing the target perception by using any one of the energy-saving perception strategies is always less than the number of perception beams transmitted by the target base station in one perception cycle in the standard state. In this way, the energy-saving operation of the target base station is realized.
