Detailed Description
In order to more clearly illustrate the present invention, the present invention will be further described with reference to examples and drawings. Like parts in the drawings are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and that this invention is not limited to the details given herein.
At present, when a shooting task, particularly an individual shooting task such as a sniping task, is executed, a shooter mainly utilizes simple measurement and a table of own organization to calculate shooting data, and the method is relatively complex in organization, consumes time and cannot guarantee accuracy. In many emergency situations, even simple measurement cannot be completed, and the measurement can be estimated only by experience of a shooter, so that shooting precision is seriously affected, and task failure is caused.
The inventor finds that a handheld weather meter and a handheld laser distance meter exist in the prior art, a shooter can measure weather data by using the handheld weather meter and the handheld laser distance meter, but the measured data are isolated and dispersed, the use of the data is still manually calculated or estimated, the efficiency is low, and the accuracy is difficult to guarantee.
In view of this, as shown in fig. 1, an embodiment of the present invention provides an auxiliary shooting apparatus including: a mobile terminal 110, a handheld weather meter 120, and a handheld laser rangefinder 130. Wherein,
A handheld weather meter 120 for collecting weather data;
A hand-held laser rangefinder 130 for acquiring a distance and a pitch angle of a target;
A mobile terminal 110 for displaying a first interface including a weapon selection control; responding to the first operation of the weapon selection control, determining the weapon type, acquiring the corresponding bullet type coefficient and resistance coefficient and displaying a second interface comprising a reading control and a starting control; in response to a second operation on the read control, reading weather data collected by the handheld weather meter 120; and responding to the third operation of the starting control, carrying out ballistic calculation according to the bullet type coefficient and the resistance coefficient, the meteorological data and the distance and pitch angle of the target, obtaining a pitch correction amount and a direction correction amount, and outputting the pitch correction amount and the direction correction amount.
The auxiliary shooting device provided by the embodiment has the advantages of portability, easiness in operation, high automation and the like, can provide accurate correction units or starting units for a shooter in various environments, enables the shooter to obtain accurate gauge and direction anytime and anywhere, and is particularly suitable for scenes in which the shooter performs individual shooting tasks. The correction data includes a pitch correction amount and a direction correction amount, and for a straight aiming weapon with low trajectory extension such as a sniper rifle, a machine gun, an assault rifle, and the like, the mobile terminal 110 outputs the correction data, and the shooter aims at the target according to the correction data. The starting data comprise a gauge (pitch angle can also be called as a high-low angle and represents the gauge) and a direction (horizontal angle), wherein the gauge and the direction are pitch correction amount and direction correction amount obtained by ballistic calculation respectively, and the starting data are output by the mobile terminal 110 for curved fire weapons with relatively curved ballistic trajectory such as antitank rockets, grenades launchers, strakes, rapid-fire mortars and the like, and the shooter can shoot after starting data according to the setting of an operation rule.
In one possible implementation, the mobile terminal 110 and the handheld weather meter 120 are connected by a data line.
In one possible implementation, the meteorological data includes wind speed data, wind direction data, air temperature data, and barometric pressure data.
In a specific example, the handheld weather instrument 120 includes a micro ultrasonic anemometer, a micro temperature, humidity and pressure integrated sensor, and the like, and the handheld weather instrument 120 has the performance of waterproof, dampproof, low temperature resistance, and the like, can measure weather data such as wind speed, wind direction, air temperature, air pressure, humidity, and the like in real time, and transmits the weather data to the mobile terminal 110 in real time through a data line. For example, the handheld weather meter 120 is configured to be highly sensitive, and is held by a shooter for weather data acquisition at 20 cm from the ground, so that the target is not easily exposed. Specifically, the handheld weather meter 120 includes components such as an ultrasonic anemometer, an air temperature sensor, an air pressure sensor, and a humidity sensor, wherein the ultrasonic anemometer as a main body is designed in a serial manner, and is designed compactly on the basis of ensuring the performances such as dust prevention, water prevention, drop prevention, explosion prevention, and the like. The various sensors are bonded within the flashing and transmit data to the mobile terminal 110 via a data line, such as a serial line.
In a specific example, the mobile terminal 110, which is the core of the auxiliary shooting device provided in this embodiment, is, for example, a smart phone or a small tablet computer, and is, for example, customized to have no wireless communication function, and has dustproof, waterproof, anti-drop, anti-explosion, and other properties. Taking a smart phone as an example, as the smart phone of the mobile terminal 110, for example, an Android operating system is adopted, and a communication mode can be set by a shooter. Has a touch screen and may be provided with a speaker and/or a headphone interface. The smart phone is further provided with an interface (e.g., type_c interface) for connecting data lines such as serial lines, and the serial communication distance is not less than 5 meters. For example, one end of a data line, such as a serial port line, is connected to the type_c interface of the smart phone, and the other end of the data line is connected to the handheld weather instrument 120 through an aviation plug, so that the smart phone is directly connected to the handheld weather instrument 120. For batteries, the smartphone, for example, a lithium polymer battery pack with 12V6AH built in, can operate continuously for more than 10 hours. The smart phone as the mobile terminal 110 is used for reading the meteorological data collected by the handheld meteorological instrument 120, performing analysis (ballistic calculation or shooting data calculation), and displaying the pitching correction amount and the direction correction amount required by the shooter or outputting the pitching correction amount and the direction correction amount required by the shooter through the touch screen.
In one particular example, mobile terminal 110 is designed with a database, such as a database for storing bullet-type coefficients and drag coefficients for each weapon type, which may be a lightweight database, such as the SQlite3 database, due to the small amount of data involved.
In a possible implementation, the mobile terminal 110 is further configured to display an ammunition selection control on the first interface;
The mobile terminal 110, configured to determine a weapon type, obtain a corresponding bullet type coefficient and a drag coefficient, and display a second interface including a reading control and an initiating control in response to a first operation of the weapon selection control, includes: responsive to a first operation of the weapon selection control and a fifth operation of the ammunition selection control, a weapon type and ammunition type are determined, corresponding bullet type coefficients and drag coefficients are obtained, and a second interface comprising a reading control and an activation control is displayed.
Thus, the auxiliary shooting device provided by the present embodiment can be applied to a case where one weapon is equipped with a plurality of types of ammunition. Continuing with the previous example, the database is used, for example, to store a bullet type coefficient and a drag coefficient for each ammunition type for each weapon type.
In a possible implementation manner, the mobile terminal 110 is further configured to display a data item on the second interface, where the data item includes at least one of a distance of the target, a pitch angle of the target, and meteorological data.
In a possible implementation manner, the data items include a distance of the target and a pitch angle of the target, and the mobile terminal 110 is further configured to obtain the distance and the pitch angle of the target in response to a fourth operation on the data items of the distance of the target and the data items of the pitch angle of the target.
Because wireless technologies such as WiFi, bluetooth, etc. are highly susceptible to interference in the battlefield, the present implementation adopts a manner in which the measurement results are manually input to the mobile terminal 110 by the shooter of the distance and pitch angle of the target acquired by the hand-held laser rangefinder 130. In addition, the mobile terminal 110 may be connected to the handheld weather meter 120 through a data line, and the handheld laser rangefinder 130 obtains the distance and pitch angle of the target and transmits the obtained distance and pitch angle to the mobile terminal 110 through the data line.
In one specific example, the hand-held laser rangefinder 130 includes an eyepiece display screen and an angle sensor (gyroscope), such as a laser range finding altitelescope, further such as a monocular laser range finding altitelescope. For example, the laser ranging altimeter telescope is designed in a one-key operation mode, that is, the laser ranging altimeter telescope is provided with a locking key, for example, after a shooter uses an aiming point of a division line center of the laser ranging altimeter telescope to aim at a target, the laser ranging altimeter telescope is used for acquiring a distance and a pitch angle (a pitch angle can also be called as a height angle) of the target aimed at by the aiming point in response to the operation of the shooter pressing the locking key, and the distance and the pitch angle are displayed on an eyepiece display screen, for example, as shown in fig. 2, the distance and the pitch angle of the target are 806m, and the pitch angle is 58.8 degrees, so that the shooter can apply, for example, clicking a data item frame to a data item of the distance of the target and a data item of the pitch angle of the target displayed on a second interface according to the distance and the pitch angle of the target, for example, a fourth operation of inputting a numerical value on a popup touch keyboard window is performed by the mobile terminal 110 in response to the fourth operation. In addition, the laser ranging altimeter telescope has the following design: long standby time, short distance measurement interval, 1500 meters of measurement range (namely, the distance and pitch angle of the target within 1500 meters can be measured), less than 5 meters of distance measurement error, and the like.
In one possible implementation of the present invention,
The handheld weather instrument 120 is configured to collect weather data in real time;
The mobile terminal 110 is configured to read, in response to the second operation of the reading control, weather data that is newly collected by the handheld weather meter 120 at a set time interval; in response to the third operation of the start control, after the latest collected meteorological data of the handheld meteorological instrument 120 is read each time, ballistic calculation is performed according to the bullet type coefficient and the resistance coefficient, the meteorological data, and the distance and pitch angle of the target, so as to obtain a pitch correction amount and a direction correction amount, and output the pitch correction amount and the direction correction amount.
Because weather conditions, particularly wind speed and wind direction, may change at any time, in this implementation, the handheld weather meter 120 collects weather data in real time, and the mobile terminal 110 reads the latest collected weather data of the handheld weather meter 120 once every one to three seconds, for example, and performs ballistic calculation according to the latest collected weather data to obtain and output the latest pitch correction amount and the latest direction correction amount, so that the pitch correction amount and the latest direction correction amount can be ensured to adapt to the influence of external condition changes at any time, and shooting accuracy is ensured.
In a specific example, for core function-ballistic calculation of the mobile terminal 110, the mobile terminal 110 accurately simulates a real trajectory using a bullet factor and a resistance factor corresponding to a selected weapon ammunition based on a C43 (43 years law of resistance) ballistic factor, for example, the mobile terminal 110 performs a ballistic integration calculation using a langerhans-kuda method according to the bullet factor and the resistance factor, the meteorological data, and the distance and pitch angle of the target. The corresponding ballistic section can be intercepted through the complete ballistic shape, the distance and the pitch angle of the target, and the ballistic space position is pre-calculated so as to calculate the correction data or the starting data of the weapon.
Among them, the Longer-Kutta method (Runge-Kutta methods) is an important class of implicit or explicit iterative method for solution of nonlinear ordinary differential equations in numerical analysis, which is a single-step algorithm with wide application of high precision in engineering, including the well-known Euler method, for numerically solving differential equations.
Further, the mobile terminal 110 performs trajectory integration calculation by using a rongeur-kuda method according to the bullet shape coefficient and the resistance coefficient corresponding to the weapon type and the ammunition type selected by the shooter based on the C43 trajectory coefficient and the weather data including wind speed, wind direction, air temperature and air pressure acquired by the handheld weather instrument 120 in real time, so as to calculate the trajectory curve of the projectile, calculate the intersection point of the trajectory curve and the target vertical plane or the horizontal plane (for example, for a direct aiming weapon, calculate the intersection point of the trajectory curve and the target vertical plane, for a curved fire weapon, calculate the intersection point of the trajectory curve and the target horizontal plane, but refer to the intersection point position of the other plane), and thus calculate the trajectory correction amount according to the calculated trajectory correction amount, calculate the intersection point with the two planes again, and finally determine correction units or start units through repeated correction and trajectory calculation. The trajectory correction amount is estimated in the case that the trajectory and the target do not coincide in one trajectory integral calculation, and then the trajectory integral calculation is performed again until the trajectory curve coincides with the target, and three to four trajectory integral calculations are generally performed, wherein the density of integral points can be adjusted according to the curvature of different trajectory segments, so that the calculation amount of the trajectory integral calculation is reduced, and the time taken by three continuous trajectory integral calculations is not more than 0.1 seconds.
For example, the handheld weather instrument 120 may be provided with a switch such as a key, and the handheld weather instrument 120 is turned on in response to the operation of the switch by the shooter, and the acquisition of weather data is continued after the turn-on; or the handheld weather instrument 120 is configured to be connected with the mobile terminal 110 through a data line, namely triggered to be started so as to continuously collect weather data; or the handheld weather meter 120 is configured to be turned on to continuously collect weather data after receiving an on signal sent by the mobile terminal 110 in response to an on-collecting operation applied by a shooter (for example, the mobile terminal 110 displays an on-collecting control on a first interface, a second interface or the like, and the on-collecting operation is that the shooter clicks the on-collecting control).
In one possible implementation, the mobile terminal 110 outputting the pitch correction amount and the direction correction amount includes: and displaying the pitch correction amount and the direction correction amount on a third interface for the shooter to view.
In one particular example, mobile terminal 110 may also display the full ballistic coefficient and the ballistic trajectory at a third interface for viewing by a shooter.
In one possible implementation, the mobile terminal 110 outputting the pitch correction amount and the direction correction amount includes:
in the case of a weapon of the direct aiming type:
for a direct aiming weapon adopting an optical sighting telescope, a dividing line, a reference aiming point and an actual aiming point determined according to the pitching correction amount and the direction correction amount of the optical sighting telescope are graphically displayed on the third interface;
for a direct-view weapon using a mechanical sighting telescope, the target profile reference point and the actual aiming point determined from the pitch correction and the direction correction are graphically displayed on the third interface.
In one particular example, a weapon type selection interface (first interface) is shown in FIG. 3, where a shooter may select a weapon type by clicking on various weapon type selection item controls, and mobile terminal 110 determines the weapon type in response to the shooter's clicking operation. It will be appreciated that figure 3 shows only three types of sniper rifle type weapons, and that the present embodiment may support a greater number of weapon types, including, by way of example, 7 broad categories of 15 weapon types, including 3 sniper rifle, 3 machine guns, 4 mortars, 2 antitankles, 1 grenade launcher, 1 sealess cannon, and 1 rapid fire mortar, and display interactions may be performed using a hierarchical interface display (i.e., the weapon type selection interface includes a category selection interface, and if the shooter selects a sniper rifle, a selection interface for a particular type of sniper rifle such as that shown in figure 3) or the like. In addition, the ammunition selection control may be designed similar to the weapon type selection item control shown in FIG. 3.
Continuing the foregoing example, as shown in fig. 4, the computing interface (second interface) displays a reading control "reading weather instrument", a starting control "trajectory calculation" and data items of all weather data and target distance and target pitch angle data items located at the upper part, and a shooter can click the reading control "reading weather instrument" to enable the mobile terminal 110 to read the weather data collected by the handheld weather instrument 120 and display the weather data in the data items of all weather data, can click the target distance data item and the target pitch angle data item to perform input operation so that the mobile terminal 110 obtains the distance and pitch angle of the target, can click the data items of all weather data to perform manual correction, and in addition, the shooter can set parameters such as display units of weather data such as air pressure and wind direction, set parameters such as on-site magnetic declination angle according to different weapon requirements, set a mode of the mobile terminal 110 to read the weather data collected by the handheld weather instrument 120 according to a reading setting control (not shown in fig. 4) to perform single reading or intermittent continuous reading, and the like.
Under the calculation interface shown in fig. 4, after the shooter determines the meteorological data, the target distance and the target pitch angle, the shooter can click the start control "ballistic calculation" to make the mobile terminal 110 perform ballistic calculation to obtain the pitch correction amount and the direction correction amount, and jump to the result display interface (third interface) for display output. Or the shooter clicks the start control "ballistic calculation" to make the mobile terminal 110 enter the confirmation interface shown in fig. 5, where the confirmation interface displays an inputtable return-to-zero distance data item, an uncorrectable weather data item, an uncorrectable target distance and pitch angle data item, a return control for returning to the calculation interface shown in fig. 4, and a confirmation calculation control, and the mobile terminal 110 performs ballistic calculation to obtain a pitch correction amount and a direction correction amount in response to the shooter clicking the confirmation control in the confirmation interface shown in fig. 5 and jumps to a result display interface (third interface) to perform display output, and may display the pitch correction amount and the direction correction amount in the pitch correction amount data item and the direction correction amount data item in the confirmation interface, respectively, as shown in fig. 5, to perform display output.
Continuing with the previous example, for a direct view weapon employing an optical sighting telescope, the result display interface (third interface) is shown in fig. 6, where the result display interface displays a pitch correction amount data item and a direction correction amount data item for displaying a pitch correction amount and a direction correction amount, respectively, and also graphically displays a division line of the optical sighting telescope, a reference aiming point 610, and an actual aiming point 620 determined according to the pitch correction amount and the direction correction amount, so that the pitch correction amount and the direction correction amount are more intuitively presented, and a shooter can directly aim at a reference.
Continuing with the foregoing example, for a direct view weapon employing a mechanical sighting telescope, the result display interface (third interface) is shown in fig. 7, where the result display interface displays a pitch correction amount data item and a direction correction amount data item that respectively display a pitch correction amount and a direction correction amount, and graphically displays a target contour, a target contour reference point (the chest center position of the outline of the human upper body), and an actual aiming point 710 determined according to the pitch correction amount and the direction correction amount, so that the pitch correction amount and the direction correction amount are more intuitively presented, and a shooter is facilitated to directly aim at a reference.
In one specific example, for a moving object, the direction and speed of movement of the object may be obtained by, for example, a laser range finder, and the direction and speed of movement of the object may be combined in ballistic calculation to obtain a pitch correction amount and a direction correction amount considering the amount of advance.
In one specific example, to increase applicability, mobile terminal 110 also includes specialized computing tools for forward, reverse, sort out junction results, etc., to provide the ability to handle more complex situations. In addition, the database of the mobile terminal 110 also stores military expertise, data and the like, so that users can review the data in time.
