[0020] The application is further described below with reference to the drawings. DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the application clearer, the technical solutions of the application are described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the application, rather than all the embodiments. Based on the embodiments of the application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the application.

[0022] The first embodiment of the application provides a method for controlling an optoelectronic radar based on a targeting pod interface, as shown in FIG. 1, which specifically comprises the following steps: Figure 1

[0023] Step S1: obtaining an interface protocol of each instruction key of a targeting pod operation interface;

[0024] In this embodiment, the interface protocol of the targeting pod operation interface comprises target selection, target selection+, target selection-, adjustment item, adjustment item+, adjustment item-, snow plow, interception, laser radiation, follow-up LOS, follow-up coordinate point, manual search and fixed axis.

[0025] Step S2: establishing a mapping relationship between each interface protocol and a working task of the optoelectronic radar; ​

[0026] In this embodiment, according to the interface protocol-task form, the mapping relationship includes: follow-LOS-follow radar, follow coordinate point-follow line of sight, snow plow-flat display scanning, image stitching-long distance search, manual search-side scanning and tracking, fixed axis-vertical scanning, interception-tracking target, laser radiation-laser radiation, adjustment item-azimuth search range or elevation search range adjustment, adjustment item-azimuth search range or elevation search range is sequentially increased, adjustment item-azimuth search range or elevation search range is sequentially reduced, target selection-target selection, target selection-target number is sequentially increased, target selection-target number is sequentially reduced,

[0027] Step S3, according to the work task to determine the working mode, and in the working mode, combined with the mapping relationship, the seeker pod operation interface is used to control the photoelectric radar to execute the work task; wherein, the working mode includes search mode and gaze mode, and the initial state of the seeker pod operation interface is gaze mode.

[0028] Specifically, since the working mode of the seeker pod is only gaze mode, the initial state of the seeker pod operation interface is gaze mode, and the working mode of the photoelectric radar includes search mode and gaze mode, so the working mode needs to be switched, and the work task is executed in the working mode.

[0029] Since the main action interval of the seeker pod is on the ground, the detection center is usually followed by other sensors or waypoints, the adjustment amount is small and the adjustment opportunity is not much. The main action interval of the photoelectric radar is in the air, the adjustment range is large and the adjustment probability is large, so the original method of adjusting the detection center of the carrier cannot be used for the head cabin section of the photoelectric radar. It is necessary to adjust the detection center according to the commonly used task interval of the photoelectric radar.

[0030] Step S31, the machine system zero position is taken as the detection center, and when the detection position change instruction is received, the detection center of the photoelectric radar is adjusted, and the adjustment formula is:

[0031]

[0032]

[0033] In the formula, a is the detection center of the photoelectric radar, is the azimuth of the carrier direction control key before moving, is the azimuth moving speed coefficient of the carrier direction control key, is the azimuth moving speed of the carrier direction control key, b is the detection elevation center of the photoelectric radar, is the elevation of the carrier direction control key before moving, is the elevation moving speed coefficient of the carrier direction control key, The carrier direction control key is a cursor on the carrier.

[0034] The switching of the working mode and the detection center adjustment function are realized by the photoelectric radar master control module. After pressing the interface instruction key, the task system sends a command to the photoelectric radar according to the interface protocol. The photoelectric radar master control module receives the command and converts it into a corresponding working task according to the mapping relationship, and runs the working mode switching and detection center adjustment functions.

[0035] In step S32, the working mode is determined according to the working task. When the working mode is determined to be the gaze mode, the infrared video is acquired, the infrared video is processed, the composite video containing characters is obtained, the composite video is sent to the carrier task system, and the carrier task system displays the composite video on the operation interface. After receiving the interception instruction, the photoelectric radar tracks the target closest to the distance detection center.

[0036] When the working task of the follow-up radar and the follow-up sighting line is executed, the photoelectric radar cabin section adopts the gaze mode to detect a specified position in a small range, and the output video changes little. Specifically, the infrared video output by the infrared detector is filtered to obtain a digital video. In the digital video, the pixel gray value is set to 255 / 0 to superimpose characters, forming a composite video. The characters include working mode and target information. The composite video is displayed on the sighting pylon operation interface, as shown in Figure 2 . Figure 2 The character "light radar" represents the current working product as a photoelectric radar, the character "follow-up sighting line" represents the current working mode as a follow-up sighting line, the character "range: 2, 2" represents the current field of view range as 2°x2°, the character "center: -30, 2" represents the current azimuth follow-up center as -30° and the pitch follow-up center as 2°, and the character "target: -30.2, 1.7" represents the target azimuth angle as -30.2° and the pitch angle as 1.7°.

[0037] The gaze function is completed by the master control module, the infrared module and the image module of the photoelectric radar. The master control module realizes the analysis of the interception instruction and controls the product to enter tracking. The infrared module acquires the infrared video detected by the infrared detector in the photoelectric radar. The image module processes the infrared video and superimposes characters.

[0038] Step S33, when determining that the working mode is the search mode, acquiring the detection video of the whole field detection of the photoelectric radar, and intercepting the video of the target appearing in the detection video to obtain the target video; acquiring the target position and the state information of the photoelectric radar, and sending them to the carrier task system, which displays the target video, the target position and the state information of the photoelectric radar on the operation interface; and after receiving the interception instruction, controlling the corresponding instruction key (target selection) to select the target position on the operation interface to track the target according to the mapping relationship.

[0039] Specifically, when performing the plan position indicator (PPI) scanning, the long-range search, the side scanning and tracking, and the vertical scanning tasks, the photoelectric radar cabin section searches the specified area in a large-range scanning and fast manner, and the operation interface displays in the search mode. Since the output video quantity is large, the video cannot be displayed in real time, and multiple targets can be found in one field search. The embodiment adopts the target video + character superposition mode for display. The embodiment takes eight targets as an example for specific introduction.

[0040] All videos of each search are acquired, and the video in which the target appears is intercepted. The size of a single video is not greater than 1 / 24 of the operation interface. If the number of targets is greater than 8, the current frame video of the eight targets with high priority is intercepted according to the target priority. The eight target videos, the target position and the state information of the photoelectric radar are displayed on the operation interface. Further, the spatial simulation characters can be drawn according to the current detection center, the detection range and the coordinates of the target position, the eight target videos and the spatial simulation characters are combined to obtain a composite video, and the composite video is displayed on the operation interface.

[0041] The search operation interface is shown in Figure 3 The upper half is the target video display area, the middle is the spatial simulation character display area, and the lower half is the target position display. The functions of the instruction keys on the left are target selection, including target selection, target selection + and target selection -. The first target is selected by default. If the target selection + is pressed, the target number is increased by 1 according to the mapping table, and the target is selected to the right in turn. If the target selection - is pressed, the target is selected to the left in turn. After the target is selected, the selected target is marked in the target video display area in the form of superimposed shadow characters, and in the spatial simulation character display area in the form of blackening. The functions of the instruction keys on the right are search range adjustment, including adjustment item, adjustment item + and adjustment item -. When the search range is pressed, the "search range azimuth" and "search range pitch" characters are alternately displayed by character superposition according to the mapping table. The azimuth search range or the pitch search range is adjusted by pressing the adjustment item + and the adjustment item - buttons.

[0042] The search function is completed by a master control module, a servo module, an infrared module and an image module of the photoelectric radar, wherein the master control module realizes functions of working mode switching, target position calculation, target selection and adjustment item calculation; the servo module controls the product to search; the infrared module acquires infrared video; and the image module intercepts target video and superimposes target position and state information.

[0043] In step S34, in the initial detection state, the corresponding instruction key (laser radiation) is controlled to turn off the radiation laser of the photoelectric radar; and in the tracking process, when the instruction of starting radiation is received, the corresponding instruction key is controlled to make the photoelectric radar radiate laser.

[0044] In the embodiment, the main task of the aiming pod is to irradiate the ground and measure the distance, and the laser radiation control is closely related to the state of the carrier; the main task of the photoelectric radar is to measure the distance of the small target in the air. Therefore, in the control of the photoelectric radar, the corresponding instruction key is controlled to turn off the radiation laser of the photoelectric radar first, and if it is needed to start in the tracking process, the corresponding instruction key is controlled to make the photoelectric radar radiate laser, so as to ensure the safety of the photoelectric radar.

[0045] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent flow transformation using the content of the specification and drawings of the present application, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
