Definitions

  • the technical field of the invention is that of devices for facilitating the positioning in the field of an artillery system.
  • Artilleries generally receive a firing order that specifies the coordinates of the objective to be treated and the nature of the shot to be made (number and type of shells to use).
  • the artillery leader directs the artillery towards the objective and a fire calculator then determines the site and field angles to be given to the artillery tube to process the objective.
  • the orientation of the artillery is a complex maneuver that requires precise knowledge of the orientation of the tube in relation to the ground and the area where the lens is located. This orientation is generally deduced from the information given by an inertial unit (or gyrometers) embedded on the vehicle and coupled to a GPS receiver.
  • the GPS makes it possible to determine the location of the vehicle in the field and the central unit makes it possible to know the orientation of the vehicle.
  • the measurement results of the inertial unit and the GPS are usually coupled to a map representing the terrain.
  • the reading of such a restitution is relatively complex and does not facilitate the rapid implementation of the artillery with the desired position.
  • the document EP 0 359 950 describes a connecting device between anti-aircraft defense systems.
  • the document FR 2 353 822 describes a pointing and calculation system for anti-aircraft fire.
  • the document WO93 / 15372 describes a method of pointing several pieces of towed artillery.
  • the object of the invention is to provide means making it possible to facilitate rapid emplacement of an artillery on a field of operation.
  • the invention makes it possible to provide information on the received firing order which facilitates the conduct of operations by the commander.
  • the invention is more particularly adapted to an implementation from an artillery mounted on a vehicle.
  • a vehicle for example a self-propelled or an artillery carried by truck.
  • the mobility capabilities of the vehicle facilitate rapid positioning of the system with a given orientation.
  • the device according to the invention then provides an aid for a quick and accurate battery setting which facilitates rapid processing of the objective with a holding time in a given position reduced to a minimum.
  • the subject of the invention is a device for assisting the positioning of an artillery system on a field of operations, characterized in that it comprises a positioning computer coupled to a human machine interface, and to least one sensor for the orientation of the artillery tube and a means for entering or receiving a positioning command, the human machine interface comprising a fixed icon showing the orientation of the artillery tube, and at least one positioning mark locating the desired orientation for the tube at the end of the positioning, the calculation means automatically moving the positioning mark relative to the fixed icon in connection with a modification made to the orientation of the artillery tube.
  • the human machine interface may comprise an arc or an arc portion surrounding the icon, this arc bearing the positioning mark locating the desired orientation for the tube at the end of the positioning.
  • the positioning mark carried by the arc may include an indication of the desired angular orientation for the tube.
  • the human machine interface may carry an encrypted indication of the actual angular orientation of the tube, an indication disposed near the fixed icon.
  • the artillery may be integral with a vehicle and have positioning capabilities in location and bearing of the tube relative to the vehicle, the positioning computer will then be coupled to a deterministic fire calculator according to the coordinates of the objective and those of the artillery what are the orientations to give to the tube in site and in deposit to treat the objective.
  • the Human Machine Interface may have on both sides of the fixed icon at least one colored angular sector delimited by the extreme orientations that it is possible to give the tube on both sides of the nominal orientation.
  • the color of the angular sector can then change when the positioning mark indicating the desired orientation will be opposite the angular sector, which will mean that the shot is possible.
  • the arc may comprise at least two zones of different colors, one representing the possible shooting zones and the other the prohibited shooting zones, the location of these zones being configurable using an input interface.
  • the human machine interface may make it possible to display the angular location with respect to the icon of at least one mask and / or firing receptacle, the geometrical characteristics of the firing mask and / or the firing receptacle being accessible by one or several specific screens.
  • the Human Machine Interface may be able to display on the same screen as the icon and the positioning mark an abbreviation of the firing order in progress, abbreviated giving in particular: the type of rocket, projectile and charge use.
  • the computer may advantageously include a touch screen for viewing the human machine interface and giving access to different input menus or visualization.
  • the figure 1 shows an artillery system 1 comprising an artillery 3 mounted on a vehicle 2.
  • the artillery is represented here very schematically. It comprises a tube 4 integral with a cradle 5 itself pivotally mounted in position on journals 6 integral with a fork 7.
  • the fork 7 is mounted swiveling bearing relative to a base 8 carried by the vehicle 2.
  • a rear stabilizer 9 to anchor the system to the ground. It comprises at least one blade 10 carried by an arm 11 with adjustable length (for example a hydraulic cylinder).
  • the arm 11 is hinged relative to the base 8. It will preferably provide an arm on each side of the vehicle.
  • the system according to the invention also comprises at least one sensor for the orientation of the tube 4 of the artillery. It thus comprises an angular sensor 12 of the orientation of the tube in site and an angular sensor 13 of the orientation of the tube in the bearing. These sensors will be for example incremental encoders coupled to motorizations (not shown) ensuring the pivoting site or deposit.
  • the artillery tube orientation sensors also include means for locating the vehicle 2 relative to a landmark. These means comprise a satellite positioning system 15 (GPS or "Global Positioning System”) coupled to an inertial unit 14, or at least one gyrometer for measuring a pivoting of the vehicle relative to a vertical axis.
  • GPS Global Positioning System
  • the gyrometers of the inertial unit also make it possible to know the angular orientation of the vehicle relative to its position given by the GPS, thus to know the nominal orientation of the tube 4 of the artillery 3 with respect to the objective.
  • nominal orientation is meant for the artillery tube that it has in the running position of the vehicle 2, oriented in the direction of advance of the vehicle in the field.
  • the sensors 12, 13, 14 and 15 are all connected to a computer 18 which is represented diagrammatically by a microcomputer but which is concretely made in the form of an electronic box secured to the vehicle and connected to a keyboard 19 and a screen 20.
  • the computer 18 is also connected to a radio receiver 21 which receives positioning orders from the artillery issued by a remote command post 22.
  • the figure 2 shows in top view the vehicle 2 carrying the tube 4 as it is oriented in nominal position.
  • the direction 16 shows the nominal orientation of the tube.
  • the direction 17 may for example be a desired orientation for the artillery tube to achieve a given objective Z.
  • the figure 3 shows more precisely the functional organization of the computer 18. This includes a microprocessor connected to memories or registers in which are incorporated the software and algorithms for the processing of information relating to shooting.
  • the computer 18 will comprise a positioning calculator part 23 which will use the information provided by the satellite positioning sensor (GPS) 15 and the inertial unit (or the gyrometer) 14 to position and orient in a fixed terrestrial frame the vehicle carrying its tube 4 oriented in a nominal way.
  • GPS satellite positioning sensor
  • the inertial unit or the gyrometer
  • the coordinates of the fixed terrestrial reference chosen will have been preprogrammed before the mission or will be received via the receiver 21.
  • the calculator 18 also includes a shooting calculator part or ballistic calculator 24. This firing calculator determines the angles of location and bearing to give to the tube 4 to process the objective.
  • the site and bearing angles may be used by a firing squad to position the tube manually, but in a preferred manner they will be used by a part control unit 27 which will automatically control the engines 41 ensuring positioning in the field and in the field. desired deposits from the instructions provided by the computer and the actual values provided by the positioning sensors 12 and 13.
  • the computer 18 comprises a module 26 for generating a human machine interface 28 which will be displayed dynamically on the screen 20.
  • This module uses the positioning and orientation data of the tube provided by the computer of FIG. positioning 23 as well as the data provided by the firing calculator 24 (coordinates of the objective, angles of site and deposit calculated).
  • the screen 20 may be a touch screen which will allow to enter orders directly on the screen and dispense with the use of the keyboard 19.
  • FIGS. 4a and 4b show a first embodiment of a human machine interface (or HMI) 28 according to the invention.
  • the HMI 28 has a fixed icon 29 appearing and embodying the orientation of the artillery tube.
  • This icon 29 is surrounded (at least partially) by an arc 30 which is angularly movable around the icon.
  • the pivoting of this arc is controlled by the module 26 of the computer in connection with a modification of the nominal orientation 16 of the artillery.
  • the modification of the nominal artillery direction 16 is caused by the maneuvering of the vehicle 2 in the field. It is detected by the positioning means 14 and 15 and more particularly by the inertial unit (or the gyrometer) 14.
  • the arc 30 and the icon 29 thus schematize a reference linked to the vehicle as it has been shown in FIG. figure 2 .
  • the firing calculator 24 coupled to the module 26 will control the display on the arc 30 of a positioning mark 31 (here a small color triangle) which locates the desired orientation for the tube 4 at the end of the positioning.
  • a positioning mark 31 here a small color triangle
  • This positioning mark 31 thus schematizes the axis 17 as it has been shown in FIG. figure 2 .
  • the display of the desired orientation is dynamic, that is to say that the positioning mark 31 will move as soon as the operator will maneuver the vehicle to position it in the field.
  • the representation of the objective 31 rather than that 29 of the artillery.
  • Such a choice facilitates the reading of the positioning information.
  • the target data are thus systematically positioned in a reference system related to the vehicle and this whatever the orientation of it in the field.
  • the fire computer 24 is programmed so that it can be determined as a function of the coordinates of the objective and those of the vehicle carrying the artillery which are the extreme orientations of the tube 4 of the part and of the other than its nominal orientation from which it is possible to treat the goal.
  • the algorithm allowing such a calculation is easy to establish taking into account the knowledge of the maximum positioning capabilities in site and field of the artillery 3 with respect to the vehicle 2 itself (maximum possible amplitudes for the displacements of the tube 4 in site and in relation to the vehicle).
  • This sector 34 is therefore at the level of the GUI 28 areas in which the firing is possible to achieve the firing target 31 associated with the positioning order.
  • the HMI module 26 of the computer 18 will be programmed so that the color of the sector 34 changes when the firing objective 31 is facing the sector 34, so in an area where firing is possible (after of course the positioning in site and location of the tube relative to the fixed vehicle).
  • the sector 34 has a grid background (which corresponds for example to a red color) meaning that the shot is impossible.
  • the sector 34 has changed color it has a gray background (which corresponds for example to a green color) and that means that shooting is possible.
  • the new orientation of the system is such that the difference between the actual nominal position of the tube 4 (1480 thousandths) and the desired orientation (1485 thousandths) is small enough for the pointing operators in site and deposit of the artillery can move the tube 4 relative to the vehicle 2 to align the tube 4 with the lens and ensure its treatment.
  • the color change will be associated with the lifting of a fire clearance at the computer 18. It will thus be possible to provide for a prohibition of the continuation of the firing process as long as the positioning mark 31 is not facing the sector. 34.
  • the invention thus further facilitates the rapid positioning of artillery in the field. Indeed it is not necessary to obtain an exact coincidence between the actual nominal direction and the desired direction.
  • the HMI makes it possible to quickly detect the color change, which means that shooting is possible (after motorized positioning of the tube only).
  • Zone 30a represents the zone in which firing is possible.
  • Zone 30b is the zone in which shooting is prohibited.
  • the geometric location of these zones is introduced into the firing calculator 24 by means of an appropriate input interface.
  • the zones are defined by the angles in thousandths of their extreme limits.
  • This input screen will be accessed from a press on the "Security limits" key 35 which is visible on the HMI 28.
  • the support on the screen is facilitated by the use of a screen 20 tactile (which avoids the use of a mouse).
  • the display of the angular localization of at least one firing mask 36 can be provided at the level of the HMI 28.
  • a firing mask is a geometric constraint of the terrain whose characteristics are entered by the firing commander before the maneuver.
  • a mask can be a building, a hill or any other element of the landscape that will impose for example a minimum angle of deposit so that it is possible to reach a goal behind the mask.
  • each target or shooting receptacle will be captured and stored in the form of firing order just like those of the objective 31.
  • the other memorized receptacles will appear on the HMI 28 only in the form of small triangles 31a, 31b of possibly different colors.
  • Pressing the "receptacle” key 38 will give access to another screen (not shown) listing the various receptacles stored in the firing computer 18 with their geometric characteristics.
  • This screen will also create or modify a receptacle and set the processing order of the different shots.
  • the computer 18 thus provides an instant update of the relative positioning of the terrain elements whose absolute coordinates are known.
  • the figure 5 shows another embodiment of the invention which improves the previous.
  • the HMI 28 still has the icon 29 with the circle 30 and the locations 31 of the objective to be treated.
  • the keys 35, 37 and 38 of access to the characteristics of the mask, the receptacle and the safety limits are always present.
  • This mode differs from the previous one in that the HMI also has, in the right part of the screen, an abstract or summary 39 of the received firing order that is being executed.
  • This firing order was for example received via the radio receiver 21 and it is of course stored in the computer 18.
  • the firing order will include, for example: a reference number, the indication of the expected firing time (39a), the type of fuse to be used (39b), the type of firing to be used (39c) and the type of load to be used (39d) (including the number of increments required).
  • the advantage of this variant is to allow the commander to give his shot preparation orders directly from the control screen of his position. It is no longer necessary to navigate through multiple screens to know what needs to be done and operations are conducted faster.
  • a tab 40 giving the values of the angles of elevation (40a) and bearing (40b) calculated by the firing calculator 24 as a function of the actual positioning 4 of the artillery tube and the coordinates of the objective.
  • This tab will be a simple reminder of the scores that will be automatically performed by the system.
  • tab 40 will allow the gun leader to give his tallying orders to his team.
