[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field based on the present application belong to the scope of protection of the present application.

[0062] In order to realize the setting of radar warning rules, an embodiment of the present application provides a method for issuing warning rules, the method comprising: displaying a background image, wherein the position of the radar and the defense zone within the effective detection range of the radar are marked in the background image; obtaining the cutting line radius for the defense zone; dividing the defense zone into multiple sub-defense zones in the background image according to an arc cutting line formed with the position of the radar as the center and the cutting line radius as the radius; setting a warning rule for at least one of the multiple sub-defense zones; issuing the position of the sub-defense zone with the warning rule and the corresponding warning rule to the radar. In the embodiment of the present application, the position of each sub-defense zone and the warning rule of each sub-defense zone are issued to the radar, thereby realizing the setting of the radar warning rule.

[0063] The following is a detailed description, see Figure 1 , Figure 1 The first schematic diagram of the method for issuing warning rules according to an embodiment of the present application includes:

[0064] S101, displaying a background image, wherein the background image is marked with a position of a radar and a defense zone within an effective detection range of the radar.

[0065] The method for issuing warning rules in the embodiment of the present application can be implemented by an electronic device. In one example, the electronic device can be a smart phone or a computer. The background image is marked with the location of the radar and the defense area within the effective detection range of the radar. In one possible implementation, the background image can also be marked with the effective detection range of the radar. The effective detection range of the radar refers to the range that the radar can detect. In one example, the effective detection range of the radar can be as follows: Figure 2 As shown in the figure. A defense zone refers to a polygonal area within the effective detection range of the radar that needs to be monitored by the radar. It is used for the deployment of the radar area. The defense zone can be defined and set according to the actual situation. For example, if the radar needs to monitor the area where Airport A is located, the area where Airport A is located can be set as the defense zone. In an example, the defense zone within the effective detection range can be as follows Figure 3 The background image is marked with the effective detection range of the radar, which allows users to intuitively observe the effective detection range of the radar and facilitate the user's sub-zone division operation.

[0066] The background image can be any image, such as a solid color image or an image with a specified pattern. In a possible implementation, the background image is an electronic map of the detection scene of the radar. The detection scene is a real-world scene that needs to be detected by the radar. The electronic map of the detection scene can directly use an existing electronic map, or a special electronic map can be established for the detection scene. The establishment method of the electronic map can refer to the relevant electronic map establishment method, which is not specifically limited in this application. In one example, the electronic map of the detection scene can use a GIS (Geographic Information System) map.

[0067] In one example, the electronic map is marked with the location of the radar, the effective detection range of the radar, and the defense zone within the effective detection range of the radar. The steps of obtaining the electronic map of the detection scene include:

[0068] Step 1: Obtain the position of the radar in the detection scene, the effective detection range of the radar, and the position of the defense zone within the effective detection range of the radar.

[0069] Step 2: Mark the position of the radar in the electronic map of the detection scene according to the position of the radar in the detection scene.

[0070] Step three: marking the location of the effective detection range of the radar in the detection scene and the location of the radar in the electronic map.

[0071] Step 4: Mark the position of the defense zone in the electronic map according to the position of the defense zone within the effective detection range of the radar in the detection scene and the position of the effective detection range of the radar in the electronic map.

[0072] In an embodiment of the present application, an electronic map of the detection scene is used as a background image, which makes it convenient for users to intuitively obtain the radar, the effective detection range of the radar, and the position of the defense zone within the effective detection range of the radar in the detection scene, and facilitates users to intuitively observe the corresponding position of each sub-defense zone in the detection scene, thereby facilitating the division of sub-defense zones.

[0073] S102: Obtain a cutting line radius for the defense zone.

[0074] Get the cutting line radius input by the user according to the displayed background image. In one example, the user can directly input the length of the cutting line radius to obtain the cutting line radius. In one example, the cutting line radius can be obtained by the position of the user's touch screen or mouse focus relative to the radar.

[0075] In a possible implementation, obtaining the cutting line radius for the defense zone includes: after receiving a cutting preparation instruction, determining the cutting line radius according to the current focus position in the background image with the position of the radar as the origin and the position of the focus as the other end point of the radius.

[0076] In one example, function buttons can be displayed while displaying the background image, wherein the function buttons include a cutting button. When the user clicks the cutting button by touching the screen or using the mouse, the user's cutting preparation instruction is received, the defense zone cutting state is entered, and the focus position is transformed into a cutting icon. The radius of the cutting line is the line segment from the radar to the focus.

[0077] In a possible implementation, the method further includes: displaying a real length of the cutting line radius in the detection scene based on a scale of the background image.

[0078] The scale of the background image is similar to that of an electronic map, and is used to indicate the ratio of the effective detection range of the radar in the background image to the effective detection range of the radar in the real detection scene. It can also be understood as the ratio of the defense zone in the background image to the defense zone in the real detection scene. In one example, after the focus enters the effective detection range of the radar, the corresponding arc cutting line can be displayed according to the current focus position. The arc cutting line is an arc with the radar as the center and the distance from the focus to the radar as the radius (i.e., the cutting line radius). During the movement of the focus, the background image can also calculate and display the actual length of the cutting line radius in the real monitoring scene according to the real-time scale, that is, the actual distance from the cutting line to the radar in the real monitoring scene. The display position of the actual length can be customized according to the actual situation. For example, the actual length can be displayed near the focus in the background image, or the actual length can be displayed near the arc cutting line in the background image, etc.

[0079] In the embodiment of the present application, the actual length of the cutting line radius in the detection scene is displayed, so that the length of the arc cutting line from the radar can be accurately known, which can improve the accuracy of sub-defense zone cutting.

[0080] S103, dividing the defense zone into a plurality of sub-defense zones in the background image according to an arc cutting line formed by taking the position of the radar as the center and the cutting line radius as the radius.

[0081] There may be only one defense zone or multiple defense zones within the effective detection range of the radar; in a possible implementation, the defense zone is divided into multiple sub-defense zones in the background image based on an arc cutting line formed with the position of the radar as the center and the cutting line radius as the radius, including: determining an arc cutting line within the effective detection range of the radar in the background image with the position of the radar as the center and the cutting line radius as the radius; for each defense zone, if the defense zone does not include the arc cutting line, the defense zone is directly used as a sub-defense zone; if the defense zone includes the arc cutting line, the defense zone is divided into multiple sub-defense zones by the arc cutting line.

[0082] The arc cutting line formed by the radar position as the center and the cutting line radius as the radius passes through at least one defense zone. The arc cutting line divides the defense zone it passes through into multiple sub-defense zones. For the convenience of description, the defense zone that does not need to be divided and is not passed through by the arc is also called a sub-defense zone, thereby obtaining multiple sub-defense zones. In an example, Figure 8 As shown, defense zone A does not include the arc cutting line, and defense zone A is directly used as a sub-defense zone; defense zone B includes the arc cutting line and is divided into two sub-defense zones by the arc cutting line; defense zone C includes the arc cutting line and is divided into two sub-defense zones by the arc cutting line.

[0083] In the process of displaying the background image, the complete arc cutting line can be displayed, or only the arc cutting line within the defense zone can be displayed. In a possible implementation, the method also includes: taking the position of the radar as the center of the circle and the radius of the cutting line as the radius, displaying the arc cutting line within the effective detection range of the radar of the background image, or displaying the arc cutting line within the defense zone of the background image.

[0084] S104: Setting an early warning rule for at least one of the multiple sub-defense zones.

[0085] The user sets an early warning rule for at least one of the multiple sub-defense zones according to actual setting requirements. In some scenarios, although there are multiple sub-defense zones, early warning rules only need to be set for some specific sub-defense zones. Therefore, early warning rules can be set for some of the multiple sub-defense zones, while other sub-defense zones may not be set. In an example, for example Figure 8 As shown, zone A is a sub-zone, zone B is divided into two sub-zones by an arc cutting line, and zone C is divided into two sub-zones by an arc cutting line. According to actual setting requirements, warning rules can be set for only one of the five sub-zones, or warning rules can be set for multiple sub-zones among the five sub-zones separately.

[0086] In a possible implementation, the setting of early warning rules for at least one of the multiple sub-defense zones includes: setting early warning rules for each of the sub-defense zones respectively. In one example, an early warning rule may be set separately for each sub-defense zone. In one example, early warning rules may be set for sub-areas within different radii with the radar as the center. In an embodiment of the present application, early warning rules for each sub-defense zone are set separately, thereby achieving a diverse setting of early warning rules, thereby increasing the diversity of radar early warning methods.

[0087] S105, sending the location of the sub-defense zone with the warning rule and the corresponding warning rule to the radar.

[0088] The location of the sub-defense zone with warning rules and the corresponding warning rules are sent to the radar, so that the radar can monitor the sub-defense zone according to the location of the sub-defense zone and issue a warning according to the warning rules of the sub-defense zone.

[0089] A position conversion is required from the background image to the actual detection scene. In a possible implementation, the position of the sub-defense zone with the warning rule and the corresponding warning rule are sent to the radar, including: step one, according to the position of the sub-defense zone with the warning rule in the background image, determine the position of the sub-defense zone with the warning rule in the detection scene. Step two, send the position of the sub-defense zone with the warning rule in the detection scene and the corresponding warning rule to the radar. In one example, the position of the sub-defense zone in the detection scene can be determined based on the scale of the background image. In one example, the position of the sub-defense zone in the detection scene can be determined based on the correspondence between the background image coordinate system and the detection scene coordinate system.

[0090] In the embodiment of the present application, the warning rules are sent to the radar, and the setting of the radar warning rules is realized. The sub-defense zone is cut by the arc cutting line obtained by the cutting line radius, which can reduce the inconsistency and inaccuracy of the distance from the sub-defense zone to the radar after cutting, compared with manually drawing lines to cut multiple defense zones separately.

[0091] In one example, the length of the cutting line radius can be obtained by inputting a length value, thereby obtaining the cutting line radius; in one example, the line segment between the focus of the touch screen or mouse and the position of the radar can be displayed. After obtaining the cutting execution instruction, for example, after the user clicks the left mouse button, the current line segment is used as the final input cutting line radius.

[0092] In the case where only one cutting line radius is obtained, in a possible implementation, setting an early warning rule for at least one of the multiple sub-defense zones includes: in the case where only one cutting line radius is obtained, setting a first early warning rule for the sub-defense zone on the inner side of the arc cutting line, and setting a second early warning rule for the sub-defense zone on the outer side of the arc cutting line.

[0093] In the case of obtaining only one cutting line radius, the sub-defense zone can be divided into a sub-defense zone inside the arc cutting line and a sub-defense zone outside the arc cutting line. A first warning rule is set for at least one sub-defense zone inside the arc cutting line, and a second warning rule is set for at least one sub-defense zone outside the arc cutting line. In an example, for example Figure 4 As shown, the first warning rule is set for the sub-defense zone inside the arc, and the second warning rule is set for the sub-defense zone outside the arc. The first warning rule and the second warning rule can be customized according to actual conditions, for example, they can be ordinary warning, alert warning or alarm warning, etc. The first warning rule and the second warning rule should be different warning rules.

[0094] In the case where multiple cutting line radii are obtained, in a possible implementation manner, setting an early warning rule for at least one of the multiple sub-defense areas includes:

[0095] When N cutting line radii are obtained, the first warning rule is set for the sub-defense zone inside the first arc cutting line, the N-i+1 warning rule is set for the sub-defense zone outside the Ni arc cutting line and inside the N-i+1 arc cutting line, and the N+1 warning rule is set for the sub-defense zone outside the N arc cutting line, wherein N is an integer greater than 1, i={1,2,…,N-1}, and in the arc cutting lines formed by each of the cutting line radii, in order from near to far from the position of the radar, they are the first arc cutting line, the second arc cutting line,…, the N arc cutting line.

[0096] In the case where only N cutting line radii are obtained, the effective detection range is divided into N+1 areas by the N cutting line radii, and the first warning rule is set for at least one sub-defense area inside the first arc cutting line, the N-i+1 warning rule is set for at least one sub-defense area outside the Ni arc cutting line and inside the N-i+1 arc cutting line, and the N+1 warning rule is set for at least one sub-defense area outside the N arc cutting line. In an example, taking N as 3, for example Figure 5 As shown, in the order of the distance from the radar from near to far, they are the first arc, the second arc and the third arc, respectively. The first warning rule is set for the sub-defense zone inside the first arc, the second warning rule is set for the sub-defense zone outside the first arc and inside the second arc, the third warning rule is set for the sub-defense zone outside the second arc and inside the third arc, and the fourth warning rule is set for the sub-defense zone outside the third arc. The first warning rule, the second warning rule, the third warning rule and the fourth warning rule can be customized according to actual conditions, and each warning rule should be a different warning rule.

[0097] In one possible implementation, see Figure 6 , the method further comprises:

[0098] S106, when the radar detects the presence of a warning object in a sub-defense zone, a corresponding warning operation is performed according to the warning rule of the sub-defense zone where the warning object appears.

[0099] For example, if the radar detects the presence of a warning object in sub-defense zone A, the corresponding warning operation will be performed according to the warning rules of sub-defense zone A.

[0100] In an embodiment of the present application, when the radar detects the presence of a warning object in a sub-defense zone, the corresponding warning operation is performed according to the warning rules of the sub-defense zone where the warning object appears, so that the warning operation can be performed with independent warning units of the sub-defense zone, and the diversity of radar warning methods is increased.

[0101] In one possible implementation, see Figure 7 , the method further comprises:

[0102] S107, using a first display method to display the arc cutting line inside the defense zone, and using a second display method to display the arc cutting line outside the defense zone, wherein the first display method is different from the second display method.

[0103] S108, after obtaining the cutting execution instruction, filtering out the arc cutting line outside the defense area.

[0104] The first display mode and the second display mode can be customized according to actual conditions. For example, the first display mode is to use solid lines, and the second display mode is to use dotted lines. Figure 8 As shown, the arc cutting line represented by the dotted line is the arc cutting line outside the defense zone, which needs to be filtered out after the cutting execution instruction is obtained, and the arc cutting line represented by the solid line is the arc cutting line inside the defense zone.

[0105] For example, after the focus enters the effective detection range of the radar, the corresponding arc cutting line can be displayed according to the current focus position. The arc cutting line is an arc with the radar as the center and the distance from the focus to the radar as the radius (i.e., the cutting line radius). Among them, the arc cutting line inside the defense zone is displayed in the first display method, and the arc cutting line outside the defense zone is displayed in the second display method. After obtaining the cutting execution instruction, for example, after the user clicks the left mouse button, the arc cutting line outside the defense zone is filtered out, and the arc cutting line inside the defense zone is displayed and retained.

[0106] In the embodiment of the present application, the arc cutting lines inside and outside the defense zone are displayed in different ways, which can facilitate the distinction between the arc cutting lines inside and outside the defense zone; after obtaining the cutting execution instruction, the arc cutting lines outside the defense zone are filtered out, and useless arc cutting lines can be filtered out, thereby reducing the visual impact of useless arc cutting lines on the sub-defense zone division.

[0107] The present application also provides a warning rule issuing device, see Fig. 9 , the device comprises:

[0108] A background image acquisition module 11 is used to display a background image, wherein the background image is marked with the position of the radar and the defense zone within the effective detection range of the radar;

[0109] A cutting line radius acquisition module 12, used to acquire a cutting line radius for the defense zone;

[0110] A sub-defense zone division module 13, used to divide the defense zone into a plurality of sub-defense zones in the background image according to an arc cutting line formed by taking the position of the radar as the center and taking the cutting line radius as the radius;

[0111] An early warning rule setting module 14 is used to set an early warning rule for at least one of the multiple sub-defense zones;

[0112] The warning rule sending module 15 is used to send the location of the sub-defense zone with the warning rule and the corresponding warning rule to the radar.
