Description

Technical Field

[0001] This application relates to the technical field of weaponry and equipment, and particularly to a method and system (platform) for realizing rapid response of mortars. Background Art

[0002] A mortar is a short-barreled, high-angle, high-trajectory-curve artillery that uses a base plate to withstand the recoil force and fires fin-stabilized projectiles. It has a simple structure, is lightweight and flexible, has a low cost, a short minimum range (as short as only 50 meters), a high firing rate (up to 30 - 50 rounds per minute), and good killing effect on unprotected targets. It is suitable for shooting at targets behind shelters and on reverse slopes. Since its invention in 1904, mortars have been widely used in wars, especially in mountain warfare and trench warfare, and are used in cooperation with small infantry units (companies, platoons, squads). They are the standard fire support weapons for infantry. As an effective weapon for infantry close-range fire support, they are still widely equipped by modern armies of various countries, especially one of the main suppression firepower equipment of border defense forces in alpine mountainous environments.

[0003] In the alpine mountain battlefield environment of our country, there are a large number and various types of border defense monitoring devices with a wide monitoring range. The anti-sneak attack combat system and mode of border defense companies are mainly as follows: Manually dig a base plate pit at a fixed position, place the base plate in the base plate pit and complete the setup of the gun; A fixed observation post composed of the company commander, scouts, calculators, communication soldiers, etc. observes the enemy situation. After discovering a target, the scout measures data such as the distance, direction to the target, and direction to the gun. The calculator checks the firing table to calculate the firing elements including the elevation and direction. The communication soldier tells the firing elements to the mortar; After receiving the firing elements, the mortar position gives the mortar a firing direction and sets the elevation, loads the shell and fires at the target.

[0004] When the current border defense forces conduct mortar shooting, they mainly determine the firing elements manually based on the positions of three parties. Specifically, the three "points" of the observation post, the target, and the mortar position usually form an obtuse triangle, with the observation post position as the obtuse vertex. As Figure 1 shown, usually the observation post sends the distance and azimuth angle to the target it obtains to the combat personnel at the mortar position. The combat personnel correct the firing elements according to experience (estimating the trigonometric relationship), or even directly approximate the distance and azimuth angle from the observation post to the target as the distance and azimuth angle from the position to the target. This calculation method actually calculates the relative position of the target; and when the target moves within a large range, usually the correction amount based on the observation post position is directly used as the correction amount for the position to execute.

[0005] Therefore, when refitting and aiming the existing technology, the accuracy is not high, the efficiency is low, and there may be human errors, and it is more difficult to operate at night. In addition, the observation post takes a long time to deploy and is difficult to meet the requirements of rapid response in anti-surprise attacks; the selection of the location of the observation post is limited and it is difficult to meet the requirements of battlefield survival. In short, the existing technology is difficult to meet the higher requirements of rapid response operations. Summary of the Invention

[0006] For this reason, the present application provides a method and platform for rapid response of mortars to solve the problems of low accuracy and low efficiency in refitting and aiming of the existing technology.

[0007] In order to achieve the above object, the present application provides the following technical solutions:

[0008] A method for realizing rapid response of a mortar, comprising the following steps:

[0009] (1) Measuring the coordinates of the reconnaissance equipment, the distance and direction of the reconnaissance target: Real-time obtaining the satellite positioning coordinates of the reconnaissance equipment itself, the distance and azimuth angle of the reconnaissance equipment to the target through the reconnaissance equipment with self-positioning function;

[0010] (2) Measuring the coordinates of the mortar: Obtaining the satellite positioning coordinates of the mortar through the self-positioning module configured for the mortar;

[0011] (3) Calculating the absolute distance and absolute direction between the gun and the target: Calculating the absolute distance and absolute azimuth angle of the mortar to the target according to the satellite positioning coordinates of the reconnaissance equipment itself, the distance and azimuth angle of the reconnaissance equipment to the target, and the satellite positioning coordinates of the mortar;

[0012] (4) Calculating the firing data: Looking up the firing table and calculating the firing data including the elevation and direction according to the absolute distance and absolute azimuth angle of the mortar to the target, and the necessary meteorological conditions;

[0013] (5) Assigning the firing direction and setting the elevation: Assigning the firing direction to the mortar according to the direction; Setting the elevation for the mortar.

[0014] Optionally, both the self-positioning function of the reconnaissance equipment and the self-positioning module configured for the mortar adopt Beidou positioning technology.

[0015] Optionally, in step (1), the target video is also obtained simultaneously and sent to the mobile terminal.

[0016] A mortar rapid response platform, comprising:

[0017] A reconnaissance and positioning system, comprising at least one reconnaissance equipment and a first self-positioning module, for real-time obtaining the satellite positioning coordinates of the reconnaissance equipment itself, the distance (also known as "reconnaissance target distance") and azimuth angle (also known as "reconnaissance target direction") of the reconnaissance equipment to the target;

[0018] A mortar carrier device is provided at a position for stably installing a mortar; the mortar carrier device is further configured with a second self-positioning module for obtaining the satellite positioning coordinates of the mortar.

[0019] A mobile terminal is used to obtain the satellite positioning coordinates of the reconnaissance device itself, the distance and azimuth angle of the reconnaissance device to the target, and the satellite positioning coordinates of the mortar, calculate the absolute distance and absolute azimuth angle of the mortar to the target, and combine with the simple meteorological conditions and look up the (electronic) firing table to calculate the firing data of the elevation and direction.

[0020] A mortar carrier device is provided at a position for stably installing a mortar; the mortar carrier device is further configured with a second self-positioning module and an absolute direction indicator. The second self-positioning module is used to obtain the satellite positioning coordinates of the mortar, and the absolute direction indicator is used to display the current firing direction of the mortar so that the user can check whether the firing direction of the mortar is consistent with the direction in the calculated firing data (the mortar can directly set this direction value in combination with an instrument that can indicate the absolute direction and thus accurately aim at the target without performing the traditional pre-relative orientation operation).

[0021] The positions for installing the mortar can be divided into prepared positions and unprepared positions.

[0022] For a prepared position, the mortar carrier device can adopt an omnidirectional mortar turntable that supports 360° omnidirectional rotation, and the mortar installed on the omnidirectional mortar turntable can follow the rotation; the omnidirectional mortar turntable is used to adjust the firing direction of the mortar according to the direction of the firing data and accurately aim at the target.

[0023] Further optionally, the omnidirectional mortar turntable adopts the form of a hollow rotating platform and is configured with a servo motor controlled by PLC programming; the hollow rotating platform includes a bracket, a driving gear, an annular driven gear, and an annular fixed disk; the servo motor is fixedly connected to the bracket, the driving gear is coaxially connected to the output shaft of the servo motor, and the annular driven gear is located on the same horizontal plane as the driving gear and meshes with each other; the annular driven gear is coaxially arranged with the annular fixed disk, and the whole is movably connected to the bracket and limited within the bracket. The annular fixed disk is fixed on the upper surface of the annular driven gear, and the upper surface of the annular fixed disk is used to fixedly install the mortar operation platform.

[0024] Further optionally, the omnidirectional mortar turntable is further configured with a backup power supply and is in hot standby.

[0025] For an unprepared position, the mortar carrier device uses a prefabricated base plate to lay on the position to replace the base plate pit to bear the base plate of the mortar, eliminating the need for manual excavation of the base plate pit and overcoming the difficulty of difficult excavation of the base plate pit in harsh battlefield environments such as alpine mountains.

[0026] Further optionally, the upper surface of the prefabricated seat plate pad is a "Y"-shaped pit that fits the bottom of the seat plate, and there are multiple pits distributed on the lower surface. The prefabricated seat plate pad as a whole has a bent shape: the bottom end of the "Y" shape is low, and the symmetric top ends of the "Y" shape are high, so that the seat plate of the mortar is placed on the prefabricated seat plate pad with a suitable front-low and rear-high inclination angle.

[0027] Optionally, the absolute direction indicator adopts a three-dimensional electronic compass or a compass. For example, a three-dimensional electronic compass can be fixedly installed on the rotating part of the omnidirectional mortar turntable (used for fixedly installing the mortar operation platform), and the user can judge whether the current firing direction of the mortar is consistent with the direction in the calculated firing data accordingly; when a three-dimensional electronic compass is not equipped, a compass can also be simply fixed on the rotating part of the omnidirectional mortar turntable or even the mortar body.

[0028] Optionally, the quick reaction platform of the mortar further includes a simple meteorological device for obtaining real-time meteorological information of the target area and sending it to the mobile terminal; the meteorological information includes information such as temperature, wind direction and wind speed.

[0029] Compared with the prior art, the present application has at least the following beneficial effects:

[0030] In the present application, by respectively configuring satellite positioning modules for the reconnaissance device and the mortar, the absolute distance and absolute azimuth angle from the position to the target are calculated through the satellite positioning coordinates of the reconnaissance device itself, the distance and azimuth angle of the reconnaissance device to the target, and the satellite positioning coordinates of the mortar; compared with the distance and direction obtained by the prior art based on relative orientation and approximate calculation, the distance between the gun and the target measured by the present application based on positioning technology, and the absolute direction of the mortar pointing to the target calculated based on coordinates are determined, eliminating the accidental errors such as the low accuracy of the observation equipment in the prior art, and eliminating the systematic errors brought by the relative orientation method in the prior art, thereby improving the accuracy of the mortar firing data. At the same time, the automation of the reconnaissance device greatly improves the execution efficiency of calculating the mortar firing data.

[0031] Based on the present application, the reconnaissance and positioning system replaces the traditional observation post. From the limitation of the past fixed observation post that must be able to simultaneously have a clear view of the mortar and the target and other combat conditions, it has changed to a mobile reconnaissance and positioning system that secretly approaches, lurks and precisely measures the target, overcoming the systematic errors brought by factors such as the uncertain operation accuracy during manual observation, relaxing the requirements for combat conditions, greatly strengthening the adaptability to the battlefield environment, and being more in line with the actual combat needs under modern warfare. At the same time, the number of commanders in the observation post is reduced, the command level is optimized and reduced, and the combat command and control efficiency is enhanced.

[0032] Based on the present application, the mobile terminal replaces the traditional computing soldiers and communication soldiers. The past wired telephone password transmission is transformed into data transmission including coordinates, distance, azimuth, and target real scene, etc. The target information is digitalized, and the transmission efficiency is enhanced. At the same time, the precise modeling calculation software and electronic firing tables in the mobile terminal overcome the problem of slow manual calculation in the past, eliminate the systematic errors brought by the approximate calculation model, and improve the efficiency and accuracy of calculating firing elements.

[0033] The present application also arranges an omnidirectional mortar turntable to assist combat personnel in automatically giving the mortar firing direction, further improving the speed of mortar installation, aiming and modification, and thus enhancing the rapid strike ability of the mortar.

[0034] The present application also takes into account the problem of difficult installation of the base plate in the alpine mountain battlefield environment, configures a portable prefabricated base plate pad, replaces manual excavation of the base plate pit on non-established positions, quickly lays and bears the base plate, further improving the speed of using the mortar, and thus enhancing the rapid strike ability of the mortar.

[0040] The following further details the present application through specific embodiments in conjunction with the drawings.

[0041] In the description of this application: Unless otherwise specified, "a plurality of" means two or more. Terms such as "first", "second", "third", etc. in this application are intended to distinguish the objects being referred to, and do not have special significance in terms of technical connotations (for example, they should not be understood as emphasizing importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0042] As Figure 2 shown, a method for realizing rapid reaction of a mortar in this application includes the following steps:

[0043] (1) Measuring the coordinates of the reconnaissance equipment, the distance and direction to the target being observed: Real-time obtain the satellite positioning coordinates of the reconnaissance equipment itself, the distance and azimuth angle of the reconnaissance equipment to the target through the reconnaissance equipment with self-positioning function;

[0044] (2) Measuring the coordinates of the mortar: Obtain the satellite positioning coordinates of the mortar through the self-positioning module configured for the mortar;

[0045] (3) Calculating the absolute distance and absolute direction between the mortar and the target: Calculate the absolute distance and absolute azimuth angle of the mortar to the target based on the satellite positioning coordinates of the reconnaissance equipment itself, the distance and azimuth angle of the reconnaissance equipment to the target, and the satellite positioning coordinates of the mortar;

[0046] (4) Calculating the firing data: Look up the firing table and calculate the firing data including the elevation and direction based on the absolute distance and absolute azimuth angle of the mortar to the target, and the necessary meteorological conditions;

[0047] (5) Assigning the firing direction and setting the elevation: Assign the firing direction to the mortar according to the direction; Set the elevation for the mortar.

[0048] The self-positioning function of the above-mentioned reconnaissance equipment and the self-positioning module configured for the mortar can adopt Beidou positioning technology.

[0049] The reconnaissance equipment measures the distance and azimuth angle to the target, and the specific measurement method is not limited; for example: the double-observation intersection method using two cameras simultaneously aiming at the target, or using a single camera with a laser rangefinder, etc.

[0050] This application breaks through the limitation that the observation post must be able to have a clear view of both the mortar and the target at the same time, reduces the traditional firing preparation time, simplifies the firing command hierarchy, improves the aiming accuracy of the mortar, thereby enhancing the combat flexibility and strike mobility of the mortar, and greatly improving the first-round hit probability and the speed and accuracy of firing correction.

[0051] In one embodiment, the calculation of the target position is mainly performed by the support software of the mobile terminal, and the combat personnel assign the firing direction and set the elevation according to the firing data calculated by the mobile terminal.

[0052] The system platform includes:

[0053] A reconnaissance and positioning system, including at least one reconnaissance device and a first self-positioning module, for real-time obtaining the satellite positioning coordinates of the reconnaissance device itself, the distance and azimuth of the reconnaissance device to the target, and the target video information;

[0054] A mortar carrier device for stably setting a mortar; the mortar carrier device is further configured with a second self-positioning module and an absolute direction indicator, wherein the second self-positioning module is used to obtain the satellite positioning coordinates of the mortar, and the absolute direction indicator is used to display the current firing direction of the mortar, so that the user can check whether the firing direction of the mortar is consistent with the direction in the calculated firing data.

[0055] A mobile terminal for obtaining the satellite positioning coordinates of the reconnaissance device itself, the distance and azimuth of the reconnaissance device to the target, the satellite positioning coordinates of the mortar, and the target video information, calculating the distance and absolute azimuth of the mortar to the target, and calculating the firing data including elevation and direction in combination with simple meteorological conditions and referring to (electronic) firing tables.

[0056] For a prepared position, the above-mentioned mortar carrier device can adopt an omnidirectional mortar turntable, which supports 360° omnidirectional rotation, and the mortar installed on the omnidirectional mortar turntable can follow the rotation; the omnidirectional mortar turntable is used to adjust the firing direction of the mortar and accurately aim at the target; the omnidirectional mortar turntable is further configured with a three-dimensional electronic compass for displaying the geographic azimuth angle and checking whether the firing direction of the mortar is consistent with the direction in the calculated firing data.

[0057] For a non-prepared position, the above-mentioned mortar carrier device adopts a prefabricated base pad to replace the base pit dug manually to bear the base of the mortar.

[0058] The above absolute direction indicator can use a three-dimensional electronic compass or a conventional compass. Preferably, a three-dimensional electronic compass is used to measure and display the direction angle of the mortar, which mainly consists of a magnetometer, a biaxial inclinometer sensor, an MCU (micro control unit), a temperature sensor, etc. Among them, the magnetometer uses three mutually perpendicular magnetic sensors, and the sensors on each axis detect the geomagnetic field intensity in that direction. The magnetometer uses the geomagnetic field to determine the north pole; the biaxial inclinometer sensor performs tilt compensation when the magnetometer is not horizontal to realize the measurement of the magnetic field direction in three-dimensional space; the MCU processes the signals of the magnetometer and the biaxial inclinometer sensor, as well as data output and soft iron and hard iron compensation. The sensor in the forward direction, called the X direction, detects the vector value of the geomagnetic field in the X direction; the sensor in the right or Y direction detects the vector value of the geomagnetic field in the Y direction; the sensor in the downward or Z direction detects the vector value of the geomagnetic field in the Z direction. The analog output signal generated by the sensor is amplified and then sent to the MCU for processing. By using a 12-bit A / D converter, the magnetometer can distinguish magnetic field changes less than 1 milligauss, so as to accurately measure the magnetic field intensity in the X and Y directions of the milligauss order.

[0059] The direction angle value can be determined by the component vector values of the geomagnetic field in X and Y: Azimuth = arcTan(Y / X). This relationship holds only when the magnetometer is parallel to the earth's surface.

[0060] When the magnetometer is tilted, a large error will occur in the azimuth value, and the size of this error depends on the position of the magnetometer and the size of the tilt angle. To reduce the influence of this error, a biaxial inclinometer sensor is used to measure the pitch angle and the roll angle. The pitch angle is the angle change in the direction from front to back; the roll angle is the angle change in the direction from left to right. The data of the pitch angle and the roll angle are converted and calculated to "pull" the vectors of the magnetometer in the three axes back to the horizontal position. The standard conversion calculation formula is as follows: Xr = Xcosα + Ysinαsinβ - Zcosβsinα, Yr = Ycosβ + Zsinβ. Among them, Xr and Yr are the values to be converted to the horizontal position, α is the pitch angle, and β is the roll angle. Usually, a ceramic matrix electrolyte sensor is used to measure the pitch angle and the roll angle, and the inclination angle value is obtained after compensation by the temperature sensor on the circuit board.

[0061] The Beidou positioning technology and the method of installing a laser rangefinder and a gyroscope sensor on the monitoring device are used to locate the target. When necessary, a single soldier can carry a positioning rangefinder to complete the positioning. Then the mortar locates its own coordinates, and the mobile terminal calculates the coordinate deviation angle between the mortar and the target. The motor of the omnidirectional mortar turntable rotates the coordinate deviation angle to align the firing direction of the mortar with the target, completing the assignment of the firing direction.

[0062] The functions of the above-mentioned mobile terminal can be realized by the mobile terminal on the battlefield, or jointly realized by the mobile terminal on the battlefield and the terminal of the command post (border defense company) far away from the battlefield.

[0063] For example, the mobile terminal on the battlefield can directly communicate with the reconnaissance and positioning system to obtain reconnaissance data (the satellite positioning coordinates of the reconnaissance equipment itself, the distance and azimuth angle of the reconnaissance equipment to the target, the satellite positioning coordinates of the mortar, and the target video information), and report it to the command post (the mobile terminal of the command post can also communicate with the reconnaissance and positioning system to obtain the above-mentioned reconnaissance data); after receiving the strike order issued by the command post, the personnel on the battlefield use the mobile terminal on the battlefield to calculate the distance and absolute azimuth angle of the mortar to the target, and combine the simple meteorological conditions and look up (electronic) firing tables to calculate the firing elements including elevation and direction.

[0064] Another example is that the mobile terminal on the battlefield may not communicate with the reconnaissance and positioning system, but the terminal of the command post communicates with the reconnaissance and positioning system to obtain reconnaissance data (the satellite positioning coordinates of the reconnaissance equipment itself, the distance and azimuth angle of the reconnaissance equipment to the target), and sends it to the mobile terminal on the battlefield together with the strike order; the mobile terminal on the battlefield calculates the distance and absolute azimuth angle of the mortar to the target based on the above-mentioned reconnaissance data and the satellite positioning coordinates of the mortar obtained separately, and combines the simple meteorological conditions and looks up (electronic) firing tables to calculate the firing elements including elevation and direction.

[0065] The main components in the system platform are further described in detail below:

[0066] A. Reconnaissance and positioning system

[0067] The reconnaissance and positioning system includes a camera, a Beidou positioning module, and a laser ranging module. The reconnaissance and surveillance equipment can be fixedly installed at a certain geographical location, or loaded on an unmanned aerial vehicle, a small ground unmanned reconnaissance vehicle, or carried by an individual soldier acting as an observation post. By adding a positioning (direction) module and a ranging module to the existing fixed cameras, unmanned aerial vehicles and other reconnaissance and surveillance equipment on the border defense, the self-coordinates and the distance and azimuth angle to the target can be measured. The selected modules should be suitable for harsh battlefield environments such as high altitude and severe cold, and can accurately measure the self-coordinates of the reconnaissance and surveillance equipment and the distance and azimuth angle to the target; the following advantages are specifically brought:

[0068] First, the number of personnel in the observation post is reduced. The traditional observation post of 4 to 6 people is changed to an intelligent camera, an unmanned aerial vehicle, or an individual soldier carrying advanced reconnaissance equipment acting as an observation post.

[0069] Second, the speed of observing the target is improved. The traditional manual observation is changed to the automatic observation of the reconnaissance equipment.

[0070] Thirdly, the traditional command method is simplified. The two-level command of the traditional "observation post commander - position commander" can be changed to the one-level command of "position commander".

[0071] B. Omnidirectional mortar turntable

[0072] As Figure 3 shown, the omnidirectional mortar turntable adopts the form of a hollow rotating platform and is equipped with a servo motor controlled by PLC programming; the hollow rotating platform includes a bracket 1, a driving gear 2, an annular driven gear 3 and an annular fixed disk 4; the servo motor 5 is fixedly connected to the bracket 1, the driving gear 2 is coaxially connected to the output shaft of the servo motor 5, and the annular driven gear 3 is located on the same horizontal plane as the driving gear 2 and meshes with each other; the annular driven gear 3 is coaxially arranged with the annular fixed disk 4, and the whole is movably connected to the bracket 1 and limited within the bracket 1. The annular fixed disk 4 is fixed on the upper surface of the annular driven gear 3, and the upper surface of the annular fixed disk 4 is used for fixedly installing the mortar operation platform.

[0073] The considerations are as follows:

[0074] a) Considering the problem of bearing the recoil force, the overall design of the omnidirectional mortar turntable adopts a method similar to that of a hollow rotating platform, semi-sinking into the ground to conduct the recoil force, which is more stable.

[0075] b) The omnidirectional mortar turntable is rotated by a servo motor controlled by PLC programming to meet the requirements of high precision.

[0076] c) An external encoder, that is, an angle sensor, can also be installed between the omnidirectional mortar turntable and the mortar barrel to further improve the gun position accuracy.

[0077] d) Considering the uncertainty of the battlefield, the omnidirectional mortar turntable is also equipped with a backup power supply, and the backup power supply is in hot standby usually.

[0078] By upgrading and transforming the existing mortar positions on the border defense, an omnidirectional mortar turntable that can automatically locate and turn can be built, which can automatically set the absolute direction angle to make the mortar accurately aim at the target, meeting the construction requirements of the existing position conditions for border defense combat; specifically, the following advantages are brought:

[0079] Firstly, the traditional method of assigning the firing direction of the mortar is subverted. The three-step method of assigning the firing direction of the traditional "assigning the reference firing direction - manual measurement by the observation post - single adjustment of the mortar" is changed to obtaining the absolute azimuth angle of the mortar to the target in one step by "using the coordinates of the target and the mortar".

[0080] Secondly, the traditional concept of the observation post is subverted. The traditional "observation post composed of the company commander, scouts, calculators, communication soldiers, etc." is changed to "reconnaissance equipment or individual scouts acting as mobile observation posts", greatly improving the battlefield survival ability and observation efficiency of the observation post.

[0081] Three have overturned the limitations of traditional mortar positions. The traditional fixed mortar position has been changed into an omnidirectional mortar turntable that can rotate 360°. While carrying the mortar, it can also automatically complete the assignment of the firing direction of the mortar.

[0082] The omnidirectional mortar turntable can be specifically divided into two schemes:

[0083] In the first scheme, the omnidirectional mortar turntable can only rotate horizontally. Therefore, for the elevation direction, the gun crew soldiers need to manually operate and set the sight scale by rotating the elevation mechanism of the mortar (indicating the firing distance after comprehensively considering the influencing factors of shooting under a certain charge number).

[0084] In the second scheme, the omnidirectional mortar turntable also supports setting the sight scale within the elevation angle range of 45°. Then, it can realize the full-automatic assignment of the firing direction and setting of the sight scale. The mortar operators usually only need to check and confirm.

[0085] C. Support software (involving the mobile terminal of the mortar and the terminal of the border defense company)

[0086] Develop the support software for the connection platform device with functions such as communication and calculation, which can run on the computer side and also on the handheld side such as military mobile phones. The support software is mainly used to receive the measurement data of the reconnaissance and surveillance equipment and automatically calculate the target coordinates and firing data (distance, direction); the following advantages are specifically brought:

[0087] First, the speed of calculating the firing data is faster. The traditional calculation and correction of the firing data take several minutes to complete, while the operation speed of the software is at the microsecond level. Thus, while the reconnaissance and surveillance equipment discovers the target, the firing data (gun-target distance and absolute direction angle) can be obtained for the position.

[0088] Second, the accuracy of the firing data is higher. Software calculation can effectively avoid human errors and reduce systematic errors. At the same time, the accuracy of the distance and positioning coordinates measured by the advanced reconnaissance and surveillance system is also higher than that of the traditional measurement equipment and the positioning coordinates obtained by chart work.

[0089] Therefore, compared with the traditional mortar shooting system as a whole, this weapon platform enters the combat state faster, is easier to operate, has a more simplified command process, consumes less physical strength, and requires fewer combat personnel. At the same time, the core technology and design concept of the platform can also be improved and applied to other weapon equipment such as heavy machine guns.

[0090] D. Prefabricated base pad

[0091] For the conventional structure of the prefabricated base plate pad, reference can be made to Chinese Patent Document CN205209344U. Further optimizations have been made in this embodiment: the upper surface of the prefabricated base plate pad is a "Y"-shaped pit that fits the bottom of the base plate, and the lower surface has several circular (preferably circular, triangles, polygons, etc. are also acceptable) pits. The overall "Y" shape of the prefabricated base plate pad has a lower bottom end and higher symmetric top ends, so that the mortar base plate shows a proper front-low and rear-high inclination angle after being placed on the base plate pad.

[0092] The prefabricated base plate pad is made of a polyester composite material that is relatively light in weight, strong in hardness and has a certain degree of deformability. The strong hardness enables it to withstand the powerful recoil within a very short time when the mortar shell is launched. The deformability plays a certain buffering role, preventing the base plate pad from rebounding the mortar base plate due to the recoil force when firing the shell.

[0093] The shape of the prefabricated base plate pad is similar to the base plate pit dug manually, and it is used to support and connect the mortar base plate on the spot during combat, eliminating the need for manual excavation of the base plate pit; specifically, the following advantages are brought:

[0094] First, the speed of setting up the base plate is faster. In the alpine mountain environment, it takes more than 10 minutes to manually dig the base plate pit in the traditional way, but it can be completed within 1 minute using the new material base plate pad, solving the difficulty of setting up the base plate in alpine mountain combat.

[0095] Second, the stability of the base plate is stronger. In the traditional method, the stability of the base plate depends on the quality of manual operation, while the shape of the new material base plate pad fits the mortar base plate better, with a better effect of withstanding the recoil force, resulting in higher shooting accuracy and probability of hitting the target.

[0096] In addition, this mortar quick reaction platform can also be incorporated into the battlefield meteorological information system (battlefield weather station) to obtain real-time meteorological information of the target area and send it to the fixed terminal of the border defense company and / or the mobile terminal of the gun crew; the meteorological information includes temperature, wind direction and wind speed. The terminal of the command post combines the position information and meteorological information related to the target to provide data support for the gun crew to select the charge number and calculate the sight. Exemplarily, the main process of assigning the firing direction and setting the sight is as follows:

[0097] 1) The camera discovers the target and measures the distance;

[0098] 2) The Beidou module locates the target, combines the gun position coordinates for orientation, and obtains the direction deviation angle of the gun platform;

[0099] 3) According to the direction deviation angle obtained by the Beidou module, the omnidirectional gun platform automatically points to the target;

[0100] 4) Information collection and analysis obtain the altitude, gun-target distance, gun-target height difference and meteorological information, and perform preliminary calculation;

[0101] 5) Mortar operators select the charge number based on the above information and the actual situation, and calculate the elevation.

[0102] Compared with the traditional way of using guns, the all-weather monitoring equipment on the platform replaces the observation post. The omnidirectional mortar turret is used for setting and aiming. Software modeling and calculation eliminate many steps of manual measurement by soldiers, such as angle and distance conversion and azimuth calibration. Therefore, this weapon platform can enter the combat state faster, with simpler operation, more streamlined command process, less physical consumption, higher stability, and fewer combat personnel.

[0103] Based on the above embodiments, a new generation of battlefield reconnaissance and surveillance equipment family integrating functions such as Beidou positioning, ranging, and direction finding can be further designed and manufactured, enabling equipment such as reconnaissance drones and helmet-mounted cameras to have the ability to locate targets upon discovery. The existing mortars are (semi)-automatically modified for loading, aiming, and firing, so that the mortars can (semi)-automatically set the firing data while discovering and locating the targets, that is, automatically complete the firing preparation. The automated and information-based combat capabilities of mortars are further enhanced.

[0104] Furthermore, in the future, the weapon platform will be upgraded with "5G+" integration, miniaturization, and full automation to achieve "Internet of Everything" for various weapons and equipment in the border battlefield environment, completely subverting the traditional mortar combat concept, and ultimately achieving the actual combat effect of "discovering and destroying targets upon discovery".

[0105] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written out should also be considered to be within the scope described in this specification.

[0106] In the above text, the present application has been described in a relatively specific and detailed manner through general descriptions and specific embodiments. It should be understood that based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; but as long as they do not depart from the technical concept of the present application, the technical solutions obtained through these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
