Detailed Description

In order to more clearly illustrate the present invention, the present invention will be further described with reference to the following examples and the accompanying drawings. Similar parts in the figures 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 is not to be taken as limiting the scope of the invention.

The inventor finds that in the prior art, a handheld meteorological instrument and a handheld laser range finder exist, a shooter can use the handheld meteorological instrument to measure meteorological data, but the measured data are isolated and dispersed, the data are still calculated or estimated manually, the efficiency is low, and the accuracy is difficult to guarantee.

In view of the above, as shown in fig. 1, an embodiment of the present invention provides an auxiliary shooting apparatus including: mobile terminal 110, handheld weather meter 120, and handheld laser rangefinder 130. Wherein the content of the first and second substances,

a hand-held weather meter 120 for collecting weather data;

a handheld laser range finder 130 for obtaining a distance and a pitch angle of the target;

a mobile terminal 110 for displaying a first interface containing a weapon selection control; responding to a first operation of the weapon selection control, determining the type of the weapon, acquiring a corresponding bullet type coefficient and a resistance coefficient, and displaying a second interface containing a reading control and a starting control; reading meteorological data collected by the handheld meteorological instrument 120 in response to a second operation on the reading control; responding to a third operation of the starting control, carrying out ballistic trajectory calculation according to the bullet type coefficient and the resistance coefficient, the meteorological data, the distance of the target and the pitch angle, obtaining a pitch correction quantity and a direction correction quantity, and outputting the pitch correction quantity and the direction correction quantity.

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 data or starting data for a shooter in various environments, enables the shooter to obtain an accurate gauge and direction at any time and any place, and is particularly suitable for scenes in which the shooter executes individual shooting tasks. The correction data comprises a pitch correction quantity and a direction correction quantity, for the direct-vision weapons with low ballistic extension, such as a sniper rifle, a machine gun, an assault rifle and the like, the mobile terminal 110 outputs the correction data, and a shooter can shoot aiming at a target according to the correction data. The starting data includes gauge rules (the pitch angle can also be called a high-low angle, and the characterization gauge rules) and directions (horizontal angles), the gauge rules and the directions are pitch correction and direction correction obtained by trajectory calculation, for curved fire weapons with relatively curved trajectories, such as antitank rockets, grenade launchers, recoil guns, mortar and fast-fire mortar, the mobile terminal 110 outputs the starting data, and the shooter sets the starting data according to the operation rules and then shoots.

In one possible implementation, the mobile terminal 110 and the hand-held 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 air pressure data.

In a specific example, the hand-held weather meter 120 includes a micro ultrasonic anemoclinograph, a micro temperature and humidity pressure integrated sensor, and the like, and the hand-held weather meter 120 has waterproof, moisture-proof, low temperature-resistant, and the like properties, and can measure weather data such as wind speed, wind direction, temperature, air pressure, humidity, and the like in real time and transmit the data to the mobile terminal 110 in real time through a data line. For example, the hand-held weather meter 120 is configured to be highly sensitive, and is held by the shooter at a distance of 20 cm from the ground for weather data collection, so that the target is not easily exposed. Specifically, the hand-held weather meter 120 includes components such as an ultrasonic anemoscope, an air temperature sensor, an air pressure sensor, and a humidity sensor, wherein the ultrasonic anemoscope as a main body is designed in a tandem manner, and is designed in a compact manner while ensuring performance such as dust-proof, waterproof, crash-proof, and explosion-proof. Various sensors are bonded within the waterproof sheet and transmit data to the mobile terminal 110 through a data line, such as a serial port line.

In a specific example, the mobile terminal 110, which is the core of the auxiliary shooting apparatus provided in the present embodiment, is, for example, a smart phone or a small tablet computer, and is, for example, customized without a wireless communication function, and has the performance of dust prevention, water prevention, fall prevention, explosion prevention, and the like. Taking a smart phone as an example, the smart phone as the mobile terminal 110 adopts, for example, an Android operating system, and a shooter can set a communication mode. The touch screen is provided, and a loudspeaker and/or an earphone interface can be arranged. The smart phone is also provided with an interface (for example, a Type _ C interface) for connecting a data line such as a serial port line, and the serial port communication distance is not less than 5 m. Illustratively, for example, one end of the data line of the 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 meter 120 through the aviation plug, so as to directly connect the smart phone to the handheld weather meter 120. For a battery, such as a lithium polymer battery pack with 12V6AH built in, the continuous operation time may exceed 10 hours. The smart phone as the mobile terminal 110 is used to read the meteorological data collected by the handheld meteorological instrument 120, perform decomposition analysis (trajectory calculation or shooting data calculation), and display the pitch correction amount and direction correction amount required by the shooter through the touch screen, or output the pitch correction amount and direction correction amount required by the shooter by voice.

In one particular example, mobile terminal 110 is designed with, for example, a database for storing the bullet 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, in response to the first operation on the weapon selection control, determine a weapon type, obtain a corresponding bullet type coefficient and a resistance coefficient, and display a second interface including a reading control and an activation control, includes: in response to the first operation on the weapon selection control and the fifth operation on the ammunition selection control, a weapon type and an ammunition type are determined, corresponding cartridge type coefficients and resistance coefficients are obtained, and a second interface comprising a reading control and an activation control is displayed.

Thus, the auxiliary firing device provided by the embodiment can be applied to the situation that one weapon is provided with a plurality of types of ammunition. Continuing with the previous example, a database is used, for example, to store the bullet type coefficients and drag coefficients for each ammunition type under each weapon type.

In a possible implementation manner, the mobile terminal 110 is further configured to display data items on the second interface, where the data items include at least one of a distance of a 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 pitch angle of the target.

Since the wireless technologies such as WiFi and bluetooth are very susceptible to interference in the battlefield, the present implementation adopts a manner that the measurement result is manually input to the mobile terminal 110 by the shooter by the distance and pitch angle of the target acquired by the handheld laser range finder 130. In addition, the mobile terminal 110 and the handheld weather meter 120 may be connected through a data line, and the handheld laser range finder 130 obtains the distance and the pitch angle of the target and then transmits the distance and the pitch angle to the mobile terminal 110 through the data line.

In one particular example, the handheld laser rangefinder 130 includes an eyepiece display and an angle sensor (gyroscope), such as a laser rangefinder altimeter telescope, and further such as a monocular laser rangefinder altimeter telescope. For example, the laser range telescope is designed in a one-click operation mode, that is, the laser range telescope is provided with a lock button, for example, the lock button is pressed after the shooter aligns the target with the aiming point at the center of the division line of the laser range telescope, the laser range telescope acquires the distance and pitch angle (pitch angle may also be called a high-low angle) of the target aligned with the aiming point in response to the operation of the shooter pressing the lock button, and displays them on the eyepiece display screen, for example, as shown in fig. 2, the eyepiece display screen displays the target at a distance of 806m and a pitch angle of 58.8 °, so that the shooter can apply a fourth operation, for example, clicking a data item box-inputting a numerical value in a pop-up touch control keyboard window, to the data items of the distance of the target and the pitch angle of the target displayed on the second interface, according to the distance and the pitch angle of the target viewed, the mobile terminal 110 acquires the distance and the pitch angle of the target in response to the fourth operation. In addition, the laser ranging and altimetry telescope is also designed as follows: the power waiting time is long, the distance measurement interval is short, the measurement range is 1500 meters (namely the distance and the pitch angle of a target within 1500 meters can be measured), the distance measurement error is less than 5 meters, and the like.

In one possible implementation form of the method,

the handheld meteorological instrument 120 is used for collecting meteorological data in real time;

the mobile terminal 110 is configured to respond to the second operation on the reading control, and read the latest collected meteorological data of the handheld meteorological instrument 120 at a set time interval; responding to the third operation of the starting control, after reading the latest collected meteorological data of the handheld meteorological instrument 120 each time, performing ballistic trajectory calculation according to the missile-type coefficient and the resistance coefficient, the meteorological data, and the distance and the pitch angle of the target to obtain and output a pitch correction amount and a direction correction amount.

Since meteorological conditions, especially wind speed and wind direction, may change at any time, in this implementation, the handheld meteorological instrument 120 collects meteorological data in real time, and the mobile terminal 110 reads the meteorological data collected by the handheld meteorological instrument 120 most recently every one to three seconds, for example, and performs trajectory calculation to obtain and output the latest pitch correction amount and direction correction amount according to the meteorological data, so as to ensure that the pitch correction amount and direction correction amount adapt to the influence of the change of external conditions at any time, and ensure shooting accuracy.

In one specific example, for core function-ballistic calculation of mobile terminal 110, mobile terminal 110 accurately simulates a real ballistic based on the C43(43 year law of resistance) ballistic coefficients using the corresponding bullet shape coefficients and drag coefficients of the ammunition of the selected weapon, e.g., mobile terminal 110 performs ballistic integral calculation using the longge-kudada method based on the bullet shape coefficients and drag coefficients, the meteorological data, and the distance and pitch angles of the target. Wherein, the corresponding ballistic segment can be intercepted through the complete ballistic shape and 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 longge-Kutta method (Runge-Kutta methods) is an important class of implicit or explicit iterative methods for solving nonlinear ordinary differential equations in numerical analysis, which is a high-precision single-step algorithm widely applied in engineering, including the well-known eulerian method, for numerically solving differential equations.

Further, for example, the mobile terminal 110 calculates a trajectory integral of the projectile by using the longge-kudada method according to the projectile 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, in combination with meteorological data including wind speed, wind direction, air temperature and air pressure acquired by the handheld meteorological instrument 120 in real time, and calculates an intersection point of the trajectory curve with the vertical plane or the horizontal plane of the target (for example, an intersection point of the trajectory curve with the vertical plane of the target is calculated for a direct-aiming weapon, an intersection point of the trajectory curve with the horizontal plane of the target is calculated for a curved-aiming weapon, but an intersection point with the horizontal plane of the target is calculated for a curved-shooting weapon, but an intersection point with another plane is referred to), so as to calculate a trajectory correction amount based on the trajectory integral, perform a second trajectory integral calculation, calculate an intersection point with the two planes, and perform repeated correction and trajectory calculation, finally, the correction data or the start data are determined. The method comprises the steps of calculating a trajectory integral, calculating a trajectory curve of a target, calculating the trajectory integral, and calculating the trajectory integral, wherein the trajectory integral is calculated by calculating the trajectory integral, and the trajectory curve is calculated by calculating the trajectory integral of the target, wherein the trajectory integral is calculated by calculating the trajectory integral of the target, and the trajectory curve is calculated by calculating the trajectory integral of the target, wherein the trajectory integral is calculated by calculating the trajectory curve of the target, and the trajectory curve is calculated by calculating the trajectory integral of the target, so that the calculation amount of the trajectory integral is reduced, and the time for calculating the trajectory integral of three times continuously is not more than 0.1 second.

For example, the hand-held weather meter 120 may be provided with a switch such as a button, and the hand-held weather meter 120 is turned on in response to the operation of the switch by the shooter, and the collection of weather data is continued after the turning on; alternatively, the hand-held weather meter 120 is configured to be turned on by the mobile terminal 110 through the data line, i.e., to be triggered to start continuously to collect weather data; alternatively, the handheld weather meter 120 is configured to turn on to continue the acquisition of weather data after receiving a turn-on signal sent by the mobile terminal 110 in response to a turn-on acquisition operation applied by the shooter (e.g., the mobile terminal 110 displays a turn-on acquisition control on a first interface, a second interface, etc., and the turn-on acquisition operation is a shooting of the shooter on the turn-on acquisition control).

In one possible implementation, the outputting, by the mobile terminal 110, a pitch correction amount and a direction correction amount includes: and displaying the pitching correction quantity and the direction correction quantity on a third interface for a shooter to view.

In one particular example, mobile terminal 110 may also display the full ballistic coefficient and ballistic trajectory in a third interface for viewing by a shooter.

In one possible implementation, the outputting, by the mobile terminal 110, a pitch correction amount and a direction correction amount includes:

in the case where the weapon type is a direct-aim type weapon:

In one particular example, weapon type selection interface (first interface) As shown in FIG. 3, a shooter may select a weapon type by clicking on various weapon type selector controls, and mobile terminal 110 determines a weapon type in response to a click operation by the shooter. It will be appreciated that fig. 3 shows only three types of sniper rifle type weapons, and that the present embodiment may support more weapon types, illustratively 7 major 15 weapon types, including 3 sniper rifles, 3 machine guns, 4 mortars, 2 antitank rockets, 1 grenade launcher, 1 squash cannon, and 1 rapid-fire mortar, and that display interaction may be performed using a hierarchical interface display (i.e., the weapon type selection interface includes a category selection interface that displays a selection interface for a particular type of sniper rifle, such as that shown in fig. 3, if the shooter selects the sniper rifle), and so on. Additionally, the ammunition selection control may be designed similar to the weapon type selection item control shown in FIG. 3.

Continuing with the previous example, the computing interface (second interface) is shown in fig. 4, the computing interface displays a reading control "read weather instrument", a starting control "trajectory calculation", and data items of weather data, target distance and target pitch angle located at the top, the shooter can click the reading control "read weather instrument" to make the mobile terminal 110 read the weather data collected by the handheld weather instrument 120 and display the weather data in the data items of weather data, click the data items of target distance and target pitch angle to perform input operation to make the mobile terminal 110 obtain the distance and pitch angle of the target, and click the data items of weather data to perform manual correction, and the shooter can set display units of weather data such as air pressure and wind direction, set parameters such as field magnetic deflection angle, and set the manner that the mobile terminal 110 reads the weather data collected by the handheld weather instrument 120 according to the reading setting control (not shown in fig. 4) to perform single reading of the weather data collected by the handheld weather instrument 120 Or intermittent continuous reads, etc.

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 may click the start control "ballistic calculation" to make the mobile terminal 110 perform ballistic calculation to obtain a pitch correction amount and a direction correction amount, and jump to the result display interface (the third interface) to perform display output. Or, the shooter clicks the start control to perform "ballistic calculation" to make the mobile terminal 110 enter the confirmation interface shown in fig. 5, the confirmation interface displays the zero return distance data item, the uncorrectable meteorological data item, the uncorrectable target distance and pitch angle data item, and the return control and confirmation calculation control for returning to the calculation interface shown in fig. 4, the mobile terminal 110 performs ballistic calculation in response to the shooter clicking the confirmation control in the confirmation interface shown in fig. 5 to obtain the pitch correction amount and the direction correction amount, and jumps to the result display interface (third interface) to perform display output, and in addition, the pitch correction amount and the direction correction amount may be displayed in the pitch correction amount data item and the direction correction amount data item in the confirmation interface respectively to perform display output as shown in fig. 5.

Continuing with the previous example, for a direct-aiming weapon using an optical sighting telescope, a 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 respectively displaying a pitch correction amount and a direction correction amount, and further 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 in a graphic manner, so that the pitch correction amount and the direction correction amount can be more intuitively displayed, and a shooter can directly aim at the reference.

Continuing with the previous example, for a direct-aiming weapon using a mechanical sighting telescope, the result display interface (third interface) is as shown in fig. 7, and the result display interface displays a pitch correction amount data item and a direction correction amount data item respectively displaying a pitch correction amount and a direction correction amount, and also displays a target contour, a target contour reference point (a chest center position of a human-shaped upper half body contour) and an actual aiming point 710 determined according to the pitch correction amount and the direction correction amount in a graphic manner, so that the pitch correction amount and the direction correction amount can be more intuitively displayed, and a shooter can directly aim for reference.

In one specific example, for a moving target, the moving direction and the moving speed of the target can be obtained through, for example, a laser range finder, and the moving direction and the moving speed of the target are combined in ballistic calculation to obtain a pitch correction amount and a direction correction amount considering the advance amount.

In one specific example, to increase applicability, mobile terminal 110 may also include specialized computing tools such as forward, reverse, merge work, etc. to provide the ability to handle more complex situations. In addition, military expertise, data and the like are stored in the database of the mobile terminal 110, so that a user can conveniently and timely consult the database. For example, fig. 8 shows a calculation tool calling interface, fig. 9 shows a rendezvous result sorting interface, and the mobile terminal 110 provides a commonly-used professional calculation method and a conversion formula so as to be conveniently used as a convenient tool in a reconnaissance calculation process.

Illustratively, the flow of the shooter operating the auxiliary shooting device provided by the embodiment to shoot is as follows:

and shooting the target according to the pitch correction amount and the direction correction amount.
