Description

Technical Field

[0001] The present invention belongs to the technical field of remote control, and particularly relates to a method for remotely controlling an air defense weapon based on a Qt development platform. Background Art

[0002] In modern warfare, the types and performances of air raid targets are diverse. Therefore, relying solely on a certain weapon cannot fully achieve effective air defense. It is necessary to comprehensively use various air defense weapons to build a complete air defense system with long, medium, and short ranges, and high, medium, and low altitudes for layer-by-layer interception to achieve effective air defense purposes. Multifunctional artillery has the characteristics of simple structure, long range, and high cost-effectiveness. If a search system, a tracking system, and a fire control system are added to existing artillery, a new weapon and equipment can be added to the air defense and antimissile system, greatly improving and enhancing the ability of terminal air defense and antimissile. Artillery air defense can form a complete terminal air defense and antimissile firepower network together with small-caliber self-propelled anti-aircraft guns, missile-gun combined systems, and short-range terminal air defense missile weapons, further improving the current short-range terminal air defense and antimissile system and enhancing the terminal air defense and antimissile ability. Currently, most air defense weapons are manually controlled by operators through operation buttons. In the face of complex battlefield situations and wartime pressure, operators may not be able to make decisions quickly. The method for remotely controlling an air defense weapon based on a Qt development platform can send various data of the air defense weapon operation platform to the rear command system, and after data analysis, the commander can issue operation instructions to the air defense weapon operation platform through remote communication. This is of great significance for improving the reliability of decision-making and reducing the decision-making time. Summary of the Invention

This module is mainly logically controlled by the receiverJudge17 function, which requires an array of unsigned char type with a length of 17 and a variable of unsigned char type. Parse the status of the first shell according to the data in the fourth byte of the data packet. Use an if statement to perform an AND operation on the data in the fourth byte with the hexadecimal data 0X5A. If the operation result is 1, it means the first shell is not in place; if it is 2, it means the first shell is in place and available; if it is 4, it means the first shell is in place but unavailable; if it is 8, it means the first shell is in place with a fuse fault.

And so on for a total of thirty shells.

[0030] (3) Enter the target and environmental climate data display module according to the judgment result. This module is mainly logically controlled by the receiverJudge51 function, which requires an array of unsigned char type with a length of 51 and a variable of unsigned char type. Calculate the azimuth angle of the target detected by the radar according to the data in the second and third bytes of the data packet, and calculate the elevation angle of the target detected by the radar according to the data in the fourth and fifth bytes of the data packet. The calculation algorithm is as follows:

[0031]

[0032] Where Z f and Z g respectively represent the calculated azimuth data and elevation data, d x2 represents the data in the second byte of the data packet, d x3 represents the data in the third byte of the data packet, d x4 represents the data in the fourth byte of the data packet, d x5 represents the data in the fifth byte of the data packet.

[0033]

[0034] Where Z x represents the calculated distance data, d x6 represents the data in the sixth byte of the data packet, d x7 represents the data in the seventh byte of the data packet. Calculate the speed data of the target detected by the radar according to the data in the eighth and ninth bytes of the data packet. The calculation algorithm is as follows:

[0035] Z s = d x8 + 256d x9

[0036] where Z s represents the calculated distance data, and d x8 represents the eighth byte data in the data packet, and d x9 represents the ninth byte data in the data packet.

The calculation algorithm is the same as that for the second, third, fourth, and fifth byte calculations.

[0038] The flight time of the projectile is calculated based on the twenty - sixth and twenty - seventh byte data in the data packet. The calculation algorithm is as follows;

[0039]

[0040] where Z df represents the calculated distance data, and d x26 represents the twenty - sixth byte data in the data packet, and d x27 represents the twenty - seventh byte data in the data packet. The temperature of the environment around the launcher vehicle is calculated based on the twenty - eighth and twenty - ninth byte data in the data packet. First, the twenty - eighth byte data is shifted right by 7 bits using a shift operation to obtain the most significant bit (sign bit) of the twenty - eighth byte data to determine the positive or negative of the temperature. If the sign bit is 0, it means the temperature is positive; if the sign bit is 1, it means the temperature is negative. At the same time, the temperature is calculated based on the twenty - ninth byte data in the data packet. The calculation algorithm is as follows:

[0041] Z qw = d x29

[0042] where Z qw represents the absolute value of the calculated temperature data, and d x29 represents the twenty - ninth byte data in the data packet.

[0043] (4) Enter the vehicle and command vehicle status display module according to the determination result. This module is mainly logically controlled by the receiverJudge22 function, which requires an array of unsigned char type with a length of 22 and a variable of unsigned char type to be passed in. Parse the longitude of the command vehicle based on the data in the fourth, fifth, sixth, and seventh bytes of the data packet. First, use a shift operation to shift the data in the seventh byte 7 bits to the right to obtain the highest bit (sign bit) of the seventh byte data to determine whether it is east longitude or west longitude. If the highest bit is 0, it represents east longitude; if it is 1, it represents west longitude. After confirming the east-west longitude, calculate the specific value according to the data in the fourth, fifth, sixth, and seventh bytes. The calculation formula is as follows:

[0044] Z jd = d y4 + 2 8 d y5 + 2 16 d y6 +(0x1F & d y7 ) × 2 24

[0045] where Z jd is the longitude of the command vehicle finally obtained through the operation, d y4 represents the data in the fourth byte, d y5 represents the data in the fifth byte, d y6 represents the data in the sixth byte, 0x1F is a hexadecimal number, & represents a bitwise AND operation, d y7 represents the data in the fifth byte. Parse the latitude of the command vehicle based on the data in the eighth, ninth, tenth, and eleventh bytes of the data packet. First, use a shift operation to shift the data in the eleventh byte 7 bits to the right to obtain the highest bit (sign bit) of the eleventh byte data to determine whether it is south latitude or north latitude. If the highest bit is 0, it represents north latitude; if it is 1, it represents south latitude. After confirming the north-south latitude, calculate the specific value according to the data in the eighth, ninth, tenth, and eleventh bytes. The calculation formula is as follows:

[0046] Z wd = d y8 + 2 8 d y9 + 2 16 d y10 +(0x1F & d y11 ) × 2 24

[0047] where Z wd is the latitude of the command vehicle finally obtained through the operation, d y8 represents the data in the eighth byte, d y9 represents the data in the ninth byte, dy10 Represents the tenth byte of data, d y11 Represents the eleventh byte of data. Similarly, the longitude and latitude of the launcher vehicle are parsed based on the data from the twelfth byte to the nineteenth byte in the data packet.

[0048] Step 3: Use the QLable component to display text or image data, and use the QPushButton component to display picture data while completing the events triggered by clicking the button. The QLable component is usually used as a static display component, which is not editable and can display plain text, rich text, and images. It supports setting text alignment methods and can set styles such as the font and color of the text. By calling the setPlainText method of the ui object instantiated from the QLable component, text data such as the target azimuth, target elevation, target speed, target distance, target height, follow-up azimuth, follow-up elevation, optoelectronic azimuth, and optoelectronic elevation are displayed on the QLable component. By calling the setStyleSheet method of the ui object instantiated from the QPushButton component, text and picture data are displayed on the QPushButton component. Before displaying the picture data, a resource.qrc file needs to be created and the picture is imported. In addition to displaying picture data, the QPushButton component also binds button click and double-click events through the slot function connect. Clicking the corresponding QPushButton component can trigger the corresponding event, thereby calling the corresponding function.

[0049] Step 4: Use the working state control algorithm to change the working state of the air defense weapon combat platform, use the power control algorithm to control the working state of the power supply, use the optoelectronic control algorithm to change the working state of the optoelectronic equipment, use the radar control algorithm to change the working state of the radar equipment, and use the follow-up control algorithm to change the working state of the follow-up equipment (including the follow-up equipment state and the azimuth angle and elevation angle of the follow-up equipment). Step 4 specifically includes the following steps:

[0050] (1) In the working state control algorithm, there are a total of six states: preparation configuration, marching, combat, training, supply, and fault diagnosis, which respectively correspond to six QPushButton components. When it is necessary to change the state of the air defense weapon combat platform, a secret order needs to be entered first to enter the administrator mode, and the value of the global variable kongzhimoshimima of the bool type is changed to 1. Six slot functions are used to control the six states. Clicking any QPushButton component will trigger the corresponding slot function, and the slot function will call the slots_UdpSend function to send the corresponding instruction to change the working state, and the current display state is changed through the setStyleSheet method. These six states are mutually exclusive, and only one state can be maintained at the same time.

[0051] (2) In the power control algorithm, clicking the QPushButton component of the power source triggers the signal slot mechanism and calls the slots_btnPowerControl function, which creates a power management window through PowerCtrlDlg*dlg=new PowerCtrlDlg(this). In the power management window, the slots_UdpSendPowerControl function sends instructions to change the power on and off status of the radar device, optoelectronic device, follow-up device, and control device.

[0052] (3) In the photoelectric control algorithm, by clicking the photoelectric QPushButton component to call the slots_UdpSend function to send the corresponding command, the infrared, television, and laser power-on and power-off conditions of the photoelectric device, as well as the color of the character display, character color, infrared field of view, and ranging method can be changed. By using slots_DianShiJiaoJu to create a TV focus selection form, using the QRadioButton component to create eight buttons in the TV focus selection form, and the buttons are mutually exclusive, this method can be used to control the focus of the TV.

[0053] (4) In the radar control algorithm, by clicking the QPushButton component and calling the slots_UdpSend function to send the corresponding command, the radar's rotation speed in azimuth, the tilting and erecting in pitch, and the rotation speed can be changed. The radar control module is also responsible for numbering aerial targets, manually numbering targets by calling the slots_YinDao function, and assessing the threat level of aerial targets.

[0054] (5) In the follow-up control algorithm, the follow-up device is enabled or disabled by clicking the QPushButton component. The follow-up position control window is created through the slots_SuiDongKongZhi function. The azimuth and elevation angles can be input in the window to adjust the position of the follow-up device.

[0055] Step 5: According to the threat assessment algorithm, the threat level of the aerial targets is assessed and numbered, and weighted summation is performed according to the target speed, target direction, target height and target distance. The formula is as follows:

[0056] Z wxd =0.2v+0.25q+0.25p+0.3d

[0057] Where Z wxd It represents the target threat degree after calculation, v represents the target speed, q represents the target azimuth, p represents the target elevation angle, and d represents the target distance. Then the threat degree of each target is sorted using the quick sorting algorithm. The larger the threat degree calculation value, the smaller the number.

[0058] Step 6: When the airborne target enters the optoelectronic detection range, the radar device guides the target to the optoelectronic device, and the optoelectronic device is used to track the target more accurately.

[0059] Step 7: Use the projectile mode control algorithm to select the strike mode and strike the airborne target. Trigger the signal-slot mechanism by clicking the QPushButton component of the projectile mode to call the slots_SheDanFangShi function. This function uses winFaSheQueRen = new FaSheQueRen to create a strike mode selection form. This form contains two ammunition magazines on the left and right, a total of 30 selection buttons for shells, as well as selection buttons for intelligent strike mode, single-shot strike mode, double-shot strike, and four-shot strike mode. Two arrays with a size of 15 are initialized in the strike mode selection form to store the status data of 15 shells in the left ammunition magazine and the status data of 15 shells in the right ammunition magazine respectively. 30 QPushButton components are created to trigger the signal-slot mechanism to control a total of 30 shells on the left and right, and 4 QRadioButton components are created to trigger the signal-slot mechanism to switch between the four strike modes. After selecting the intelligent strike mode, the algorithm will call a random function to randomly select the currently available shells. After selecting the single-shot strike mode, one shell needs to be manually selected from the left or right ammunition magazine. After selecting the double-shot strike mode, one shell needs to be manually selected from each of the left and right ammunition magazines. After selecting the four-shot strike mode, two shells need to be manually selected from each of the left and right ammunition magazines.
