The following is a specific description, referring to FIG. 1. FIG. 1 is a first schematic diagram of the method for issuing early warning rules in the embodiment of the present application, including:

S101. Display a background image, wherein the background image is marked with a position of a radar and at least one defense zone within an effective detection range of the radar.

The method for delivering an early warning rule in the embodiment of the present application may be implemented by an electronic device. In one example, the electronic device may be a smart phone or a computer. The position of the radar and at least one defense zone within the effective detection range of the radar are marked in the background image. In a possible implementation manner, the effective detection range of the radar may also be marked in the background image. Radar refers to a device that uses radio to find targets and determine their spatial positions. The effective detection range of radar refers to the range that radar can detect. In one example, the effective detection range of radar can be shown in Figure 2. The defense area refers to the polygonal area that needs radar monitoring within the effective detection range of the radar. It is used for the deployment of the radar area. The defense area can be customized according to the actual situation. For example, if the radar needs to monitor the area where airport A is located, you can set the area where airport A is located as a defense zone. In an example, at least one defense zone within the effective detection range may be as shown in FIG. 3 . The background image is marked with the effective detection range of the radar, which is convenient for the user to observe the effective detection range of the radar intuitively, and is convenient for the user to divide the sub-zones.

The background image can be any image, such as a solid color image or an image with a specified pattern. In a possible implementation manner, the background image is an electronic map of a detection scene of the radar. The detection scene is a real-world scene that requires radar detection. The electronic map of the detection scene can directly use the existing electronic map, or create a special electronic map for the detection scene. For the establishment method of the electronic map, please refer to the relevant electronic map establishment method. , is not specifically limited in this application. In an example, the electronic map of the detection scene may use a GIS (Geographic Information System, geographic information system) map.

In an example, the position of the radar, the effective detection range of the radar, and at least one defense zone within the effective detection range of the radar are marked in the electronic map. The steps for obtaining the electronic map of the detection scene include:

Step 1, acquiring the position of the radar in the detection scene, the effective detection range of the radar, and the position of at least one defense zone within the effective detection range of the radar.

Step 2: According to the position of the radar in the detection scene, mark the position of the radar in the electronic map of the detection scene.

Step 3: According to the effective detection range of the radar in the detection scene and the position of the radar in the electronic map, mark the position of the effective detection range of the radar in the electronic map.

Step 4: Mark the position of at least one defense zone in the electronic map according to the position of at least one 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.

In the embodiment of the present application, the electronic map of the detection scene is used as the background image, which is convenient for the user to intuitively obtain the radar, the effective detection range of the radar, and the position of at least one defense zone within the effective detection range of the radar in the detection scene, which is convenient for the user to intuitively The ground observation of the corresponding positions of each sub-defense zone in the detection scene facilitates the division of sub-defense zones.

S102. Acquire a cutting line radius for the at least one defense zone.

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

In a possible implementation manner, the acquiring the radius of the cutting line for the at least one defense zone includes: after receiving the cutting preparation instruction, according to the position of the current focus, using the radar's The position is the origin, and the radius of the cutting line is determined by taking the position of the focal point as the other end point of the radius.

In one example, function buttons can also be displayed while displaying the background image, wherein the function buttons include a cutting button, and the user clicks the cutting button through the touch screen or the mouse, that is, receives the user's cutting preparation instruction and enters the defense zone cutting state , the focus position is transformed into a cutting icon. Among them, the cutting line radius is the line segment from the radar to the focal point.

The scale of the background image is similar to the scale of the electronic map. It 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 defense zone in the background image and the real detection scene. The size ratio of the defense zone. 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 centered on the radar, and the distance from the focus to the radar is the radius (that is, The arc made by line radius). During the process of focus movement, the real length of the cutting line radius in the real detection scene can also be calculated and displayed in the background image according to the real-time scale, that is, the real distance from the cutting line to the radar in the real detection scene. The display position of the real length can be customized according to the actual situation, for example, the real length can be displayed near the focal point in the background image, or the real length can be displayed near the arc cutting line in the background image, etc.

In the embodiment of this application, the real 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, and the accuracy of sub-defense zone cutting can be improved.

S103. Divide the at least one defense zone into multiple sub-defense zones in the background image according to the arc cutting line formed with the position of the radar as the center and the radius of the cutting line as the radius.

There may be only one defense zone within the effective detection range of the radar, or there may be multiple defense zones; A line cutting line, which divides the at least one defense zone into a plurality of sub-defense zones in the background image, including: taking the position of the radar as the center and the radius of the cutting line as the radius, in the radar of the background image Determine the arc cutting line within the effective detection range; for each defense area, if the arc cutting line is not included in the defense area, the defense area will be directly regarded as a sub-defense area; if the arc cutting line is included in the defense area, the The arc cutting line divides the defense zone into multiple sub-defense zones.

The arc cutting line formed with the radar position as the center and the radius of the cutting line as the radius passes through at least one defense area. The arc cutting line divides the passing defense area into multiple sub-defense areas. For the convenience of description, the The defense zone that does not need to be divided is also called a sub-defense zone, so that multiple sub-defense zones can be obtained. In one example, as shown in Figure 8, the defense area A does not include the arc cutting line, and the defense area A is directly regarded as a sub-defense area; the defense area B includes the arc cutting line, which is divided into two sub-defense areas by the arc cutting line ;The defense area C includes the arc cutting line, which is divided into two sub-defense areas by the arc cutting line.

In the process of displaying the background image, the complete arc cutting line can be displayed, or only the arc cutting line in the defense zone can be displayed. In a possible implementation manner, the method further includes: using the position of the radar The arc cutting line is displayed in the effective detection range of the radar of the background image, or the arc cutting line is displayed in the defense zone of the background image.

S104. Set an early warning rule for at least one sub-zone in the plurality of sub-zones.

The user sets an early warning rule for at least one of the multiple sub-zones according to actual setting requirements. In some scenarios, although there are multiple sub-zones, early warning rules only need to be set for some specific sub-zones, so early warning rules can be set for some of the multiple sub-zones, while other sub-zones do not need to set early warning rules. In one example, as shown in Figure 8, the defense zone A is a sub-defense zone, the defense zone B is divided into two sub-defense zones by the arc cutting line, and the defense zone C is divided into two sub-defense zones by the arc cutting line, which can be set according to the actual situation. It is required to set the early warning rule for only one of the five sub-defense zones, or set the early warning rules for multiple sub-defense zones among the five sub-defense zones.

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

S105. Send the location of the sub-defense zone with the early warning rule and the corresponding early warning rule to the radar.

The position of the sub-defense area with the early warning rules and the corresponding early warning rules are sent to the radar, so that the radar can monitor the sub-defense area according to the position of the sub-defense area, and give an early warning according to the early warning rules of the sub-defense area.

It is necessary to convert the position from the background image to the real detection scene. In a possible implementation manner, sending the position of the sub-defense zone with the early warning rule and the corresponding early warning rule to the radar includes: Step 1. According to the position of the sub-defense zone set with the warning rule in the background image, determine the position of the sub-defense zone set with the warning rule in the detection scene. Step 2: Sending the position of the sub-defense zone with the early warning rule in the detection scene and the corresponding early warning rule to the radar. In one example, the position of the sub-zone in the detection scene can be determined based on the scale of the background image. In an example, the position of the sub-zone in the detection scene can be determined based on the correspondence between the background image coordinate system and the detection scene coordinate system.

In the embodiment of the present application, the early warning rules are sent to the radar to realize the setting of the radar early warning rules. Cutting the sub-defense area by the arc cutting line obtained by the radius of the cutting line, compared with manually drawing lines for multiple defense areas, can reduce the inconsistent and inaccurate distance between the cut sub-defense area and the radar; whether it is for Both regular and irregular defense zones can be divided into sub-zones with the same detection radius, and the setting of early warning rules for sub-regions with the same detection radius can be realized.

In one example, the length of the radius of the cutting line can be obtained by inputting the value of the length, so as to obtain the radius of the cutting line; in one example, the line segment between the focus of the touch screen or the mouse and the position of the radar can be displayed. After the cutting command is executed, for example, after the user clicks the left mouse button, the current line segment is used as the final input cutting line radius.

In the case where only one cutting line radius is obtained, in a possible implementation manner, the setting the warning rule for at least one sub-defense zone in the plurality of sub-defense zones includes: in the case of obtaining one cutting line radius Next, set the first warning rule for the sub-zones inside the arc cutting line, and/or set the second warning rule for the sub-zones outside the arc cutting line.

In the case that only one cutting line radius is obtained, 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, and at least one sub-defense zone inside the arc cutting line can be The first warning rule is set, and the second warning rule can also be set for at least one sub-zone outside the arc cutting line.

In an example, the setting of the early warning rule for at least one of the plurality of sub-zones includes: when a cutting line radius is obtained, setting the first warning rule for the sub-zones inside the arc cutting line An early warning rule, setting a second early warning rule for the sub-zones outside the arc cutting line. For example, as shown in FIG. 4 , the first warning rule is set for the defense sub-zones inside the arc, and the second warning rule is set for the defense sub-zones outside the arc. The first warning rule and the second warning rule can be customized according to the actual situation. For example, they can be general warning, warning warning or alarm warning. The first warning rule and the second warning rule should be different warning rules.

In the case where N cutting line radii are obtained, the first warning rule is set for the sub-defense zone inside the first arc cutting line, and the first warning rule is set for the sub-area outside the N-i arc cutting line and at the N-i+1 arc cutting Set the N-i+1th early warning rule for the sub-defense zone inside the line, and set the N+1th early warning rule for the sub-defense zone outside the Nth arc cutting line, where N is an integer greater than 1, i={1,2 ,..., N-1}, among the arc cutting lines formed by the radii of each cutting line, according to the order from near to far from the position of the radar, they are respectively the first arc cutting line and the second arc cutting line Cutting line, ..., Nth arc cutting line.

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