Definitions
- the invention relates to a method for simulating the threat to participants of a military exercise by hand grenades or mines according to the preamble of claim 1. It is used for realistic simulation of the threat to exercise participants, in particular soldiers and vehicles, by individual mines, mine blocks and hand grenades. In this way, training can be practiced with all (harmless) consequences and the objective influence of mines and hand grenades can be determined in simulated combat.
- a mine or hand grenade is simulated by a weapon simulator.
- the individual exercise participants (in particular personnel, vehicles) are equipped with sensors, hereinafter referred to as participant sensors.
- the effective areas of the mines and hand grenades are simulated by data transmission between the deployed weapon simulators and the participant sensor systems.
- the object of the invention is to provide a method with which a precise range limitation of the mine or hand grenade is possible, so that a reliable determination of the participants located in the effective range of the triggered mine or hand grenade is achieved. This object is achieved with the method according to claim 1.
- Advantageous designs are the subject of further claims.
- the data transmission between the weaponry simulator and the individual subscriber sensor systems is carried out in the form of a two-way radio transmission.
- the radio transmission from the individual subscriber sensors to the weapon simulator serves to delimit the effective range of the mines or hand grenade to be simulated.
- the field strength curve in the near field of the transmitting and receiving antennas involved is used for this.
- a hit is only possible if the near field of the transmitting antenna on the subscriber sensor system overlaps the near field of the receiving antenna on the weapon simulator.
- a frequency is selected as the transmission frequency, the near field range of which is greater than the maximum necessary effective range of the mine or hand grenade to be simulated.
- r ⁇ c / 2 ⁇ f frequencies in the range from a few kHz to a few 10 MHz can be used for the transmission.
- the MW and LW ranges fall into this frequency range (LW long wave, approx. 30 - 300 kHz; MW medium wave, approx. 300 kHz - 3 MHz)
- the radio transmission from the weapon simulator to the individual participant sensor systems serves to confirm or verify a mine or hand grenade hit. There is no basic input for this transfer WO 99/39148 _ g _ PCT / DE99 / 00022
- a participant is hit when there is confirmed communication between the participant sensor system and the weapon simulator.
- the effective range delimitation according to the invention by radio transmission in the near field range (e.g. in the LW or MW range) from the participant sensor system to the weapon simulator enables an exact and true-to-original effect simulation of different mine types and hand grenades. In particular, both concealed and open installation is possible.
- the radio transmission from the weaponry simulator to the individual participant sensor systems (e.g. in the UHF or VHF range), which serves to confirm a hit, ensures a high level of security in the detection of the weaponry simulators.
- Magnetic antennas eg ferrite rod with antenna coil
- the range limitation of the mines or hand grenades being achieved by utilizing the field strength curve in the near field of these antennas.
- the high damping in the transmission path has the advantage that the damping influences occurring in nature and civilization due to different ground conditions, through building, due to the weather or open and concealed laying play only a minor role.
- the method according to the invention can be used both for the simulation of mines and for hand grenades (HGR).
- HGR hand grenades
- the various properties of these systems can thus be simulated using the same technical approach.
- mine types can be simulated:
- the method according to the invention supports all usage principles of mine laying e.g. also the mixed laying of mine blocks (PzAbwVMi) and single mines (SchtzAbwVMi).
- the method is designed for mine combat simulation in combat training centers for the combat of connected weapons as well as a stand-alone solution for pure mine combat training.
- the subscriber sensor systems attached to vehicles or personnel also enable the radio connection of other devices.
- FIG. 1 shows the initial situation in the course of the method according to the invention
- FIG. 2 shows a block diagram of the overall system consisting of a combat simulator and participant sensor system
- Fig. 3 shows the radio areas of various weapon simulators and subscriber sensors.
- the transmission from a participant sensor system to the ordnance simulator takes place, for example, in the MW range, and the transmission from the ordnance simulator to the participant sensor system, for example, takes place in the UHF frequency range.
- the ordnance simulator to the participant sensor system takes place in the UHF frequency range.
- other frequency ranges are also possible.
- FIG. 1 shows the initial situation when the method according to the invention is carried out.
- Two typical exercise participants are shown, namely personnel and tanks, each of which is assigned a participant sensor system HGRM-S.
- HGRM-S participant sensor system
- HGR-KSIM PzAbwVMi-KSIM, SchtzAbwVMI-KSIM
- the SchtzAbwVMi-KSIM is triggered by the trip wire STR.
- the arrows between the individual KSIM and HGRM-S symbolize the possible transmission paths in the event of the initiation of a combat simulator.
- Fig. 2 shows an example of a block diagram of the overall system of combat agents - 6 -
- the weapon simulator KSIM shown in FIG. 2 comprises a UHF transmitter and an MW receiver.
- the subscriber sensor system HGRM-S accordingly comprises a UHF receiver and an MW transmitter.
- the MW radio link from the participant sensors to the weapon simulator (transmission in the near field) serves to limit the range and to transmit information.
- the UHF radio link from the weaponry simulator to the participant sensor system is only used for information transmission (confirmation of MW reception).
- a hit by a mine or hand grenade occurred when there was confirmed communication between the participant sensors and the weapon simulator.
- the communication between the weaponry simulator and the participant sensor system takes place in particular according to two similar methods, which are described in more detail below.
- Additional data transmission between the subscriber sensor system and a central processing and control unit can be implemented via the controller within the subscriber sensor system. For example, the fact that the participant in question was met can be transmitted for further evaluation.
- the probability of radio collisions occurring outside the procedure is due to the locally delimited transmission ranges, as well the low frequency of events (mine / HGR release, data transmission), the short transmission times (high bit rate, little data) and the non-synchronism of mine / HGR releases very low.
- the method according to the invention is open for the connection of further devices for the purpose of radio data transmission.
- the coding of the various weapons simulators and the other devices is transparent to the outside, which means that additional devices can use the data transmission path with unchanged subscriber sensors.
- the data at the interface of the subscriber sensor system HGRM-S to the central processing and control unit on the one hand and the data at the transfer interface (not shown in FIG. 2) of the ordnance simulator KSIM to the other devices are the same.
- the transmission power for data transmission to personnel and vehicles can be reduced compared to mine simulation, because here the parameters of the transmission path are more constant and only short ranges of approx. 0.1 m to 3.0 m have to be bridged.
- the data transmission has a low priority over the mine simulation, which is automatically taken into account in the subscriber sensors.
- the time utilization of the frequencies used is directly related to mine release and data transmission.
- the utilization according to the invention is reduced to a minimum.
- FIG. 3 shows, by way of example, the radio transmission ranges of individual weapon simulators and subscriber sensor systems, as are used for the method according to the invention.
- Fig. 3a the transmission - ö -
- 3b) shows the transmission range of a SchtzAbwMi ordnance simulator and a personnel participant sensor system.
- the UHF transmission ranges are represented by concentric, closed lines. The much smaller MW transmission areas are shown hatched. They correspond to the near field of the magnetic antennas used.
- the double arrow on the transmission area of the vehicle subscriber sensor system shows the direction of travel of the vehicle.
- the MW transmission ranges shown correspond exactly to the effective ranges of the PzAbwVMi or the SchtzAbwMi.
- the effective areas are reproduced by the directivity of magnetic antennas (e.g. ferrite antenna).
- magnetic antennas e.g. ferrite antenna
- a 360 ° active area or an active area in the form of a lying figure eight vehicle subscriber sensor system.
- Combinations of several magnetic antennas e.g. aligned in the direction of the x- / y- / z-axis
- the different ranges can be achieved by different attenuation of the MW receiving antenna in the weaponry simulator or by controlling the MW transmission power in the subscriber sensors.
- the SchtzAbwMi weaponry simulator the directionality in the UHF transmission range is achieved by directional radiation in the UHF range.
- Tab. 1 the sequence of a first embodiment of the invention
- the subscriber sensor system attached to a vehicle constantly sends out MW wake-up signals in accordance with Table 4. If a PzAbwVMi ordnance simulator receives a broadcast on MW, it sends out its ordnance simulator identification and the sender identification of the subscriber sensors on its UHF transmitter (telegram structure according to Table 5). The participant sensor system on the triggering vehicle recognizes this and registers and reports the reception as a hit. If other subscriber sensors receive the UHF broadcasts, then they know that the broadcast does not originate from them because it occurs asynchronously to their wake-up process and at the same time contains a foreign subscriber identification.
- the participant sensor system for personnel does not send out wake-up calls (for reasons of energy saving) and can therefore not be "hit" by PzAbwVMi, which is justified for real use.
- the described method replaces an expensive original mine sensor system in the weapon simulator and enables a high relative speed between vehicles and weapon simulator.
- an LW transmission can be used.
- VHF transmission can be used instead of the UHF transmission mentioned e.g.
- the constant MW wake-up transmissions of the participant sensors in vehicles are spatially limited to an area of approximately 8 mx 16 m, so that the vehicles do not interfere with one another. This ensures the large-scale usability of the frequency.
- Table 1 shows the described execution of the method again in detail.
- the ordnance simulators are activated by certain actions, for example trip wire triggering, electrical ignition, throwing, on the ordnance simulator itself.
- the electronics as well as the receiver and transmitter of the weapon simulator are in an inactive, battery-saving state ("sleep") until they are triggered.
- the ordnance simulator sends the mine / HGR identifier via the UHF transmitter (telegram according to Table 3), and the participants in the UHF transmission range, which is significantly larger than the mine / HGR's effective range, receive this message.
- these subscriber sensor systems controlled by a random generator, try to establish a connection via the MW transmission link to the mine / HGR.
- the maximum duration of the procedure ie with 31 participants located in the UHF transmission range of the triggering weapon simulator, is a fraction of a second.
- the participant sensor system recognizes whether damage / injury to the participant by the triggered mine type is possible at all (an example in which damage / injury is not possible is the combination of an armored vehicle / hand grenade). Only the damaged / wounded participants then carry out the described transponder procedure.
- Tab. 2 shows the described execution of the method again in detail.
- the MW transmission can be replaced, for example, by an LW transmission and the UHF transmission, for example, by a VHF transmission.
- the utilization of the frequencies used is very low. Since the participant sensor systems do not send out wake-up calls to personnel, they do not contribute to any additional radio pollution.
- the UHF frequency is used briefly several times (frame time max. 1 second / mine) within a radius of approx. 50 m to 200 m.
- the subscriber sensor systems located in the UHF reception area of the triggering weapon simulator try to establish a connection via the MW transmission path to the mine / HGR by means of transponder methods after they have received the identifier of the triggering weapon simulator. How the transmissions of the individual subscriber sensor systems are coordinated and how collision resolution is achieved is explained in more detail below.
- each participant sensor system After receiving the weapon simulator identifier, each participant sensor system calculates a random number. After a certain time, which is determined by the random number, the individual subscriber sensor system checks whether another subscriber sensor system is already transmitting. If no other participant sensor system sends, it begins with the transponder procedure described by MW transmission of the telegram according to table 4 with the participant number 1. The triggered weapon simulator answers the transmissions of the participant sensor system in such a way (telegram according to table 4) that Each subscriber sensor system in the UHF band can determine whether the MW band is being broadcast. If another participant sensor system is already transmitting, then the testing participant sensor system waits until the transponder process with the other participant sensor system has been completed.
- All subscriber sensors receive the Current identifier of the subscriber sensor system that is currently performing the transponder procedure.
- the next participant sensor system which begins with its transponder method, sends with a participant number higher by one.
- the described control of the sequence in which the individual participant sensor systems carry out the transponder method with the triggered weapon simulator, by generating and assigning random numbers, makes a large one Address space (the total number of participants who take part in the exercise can be large, e.g. in the range of 1000 participants) in a much smaller address space (the number of participants who are in the UHF reception area when the weapon simulator is triggered, will usually be less than 10). This significantly increases the speed of the method, which is particularly important for fast moving participants (eg vehicles).
- Transponder procedure he repeats his identification twice at intervals of approximately one second. If a SchtzAbwVMi, SchtzAbwMi or HGR weapon simulator detects that when the mine identification is sent for the first time, another SchtzAbwVMi, SchtzAbwMi or HGR participant sensor system carries out the transponder procedure, then the recognizing weapon simulator waits until the transponder procedure is finished and only then sends its mine identifier for the first time.
- the procedure described enables a safe selection of participants who are in the effective range of a triggered mine / HGR.
- a DF system can be used to find / locate the mines / HGR, e.g. after the exercise is finished.
- a wake-up transmitter identical to subscriber sensors
- a circular area of approx. 80 m in diameter can be searched.
- all mines deployed (HGR only after "detonation") recognize a special identifier of the alarm transmitter for the direction finding operation via their MW receiver.
- a special UHF signal for the direction finding process is then generated in the mine / HGR as long as the alarm transmitter is active.
- Commercially available direction finders are suitable as direction finders.
- the MW receiver is only pulsed after the method has been completed and is therefore operated in an energy-saving manner in order to be able to receive the wake-up transmitter of the direction finder for detection.
- the MW receiver is already operated in pulsed mode after focusing, in order to also search for mines that have not been triggered ⁇ lo -
- a major advantage of the method according to the invention is the fact that the subscriber sensor systems attached to vehicles or personnel not only enable the detection of mines but also the radio connection of further devices.
- Tab. 6 shows a telegram as an example for data transmission.
- Tab. 7 shows an exemplary telegram for confirmation.
- Participant 1 transmits MW MW reception and UHF in accordance with Tab. 4 and simultaneously receives transmission in accordance with Tab. 4 its transmission on UHF
- Participant 1 then reports / registers sleep mine hit mode for HGRM-S on participant 1
- Participant 2 transmits MW MW reception and UHF according to Tab. 4 and receives transmission according to Tab. 4 simultaneously its transmission on UHF
- Participant 2 then reports / registers sleep mine hit mode for HGRM-S on participant 2
- Participant n sends MW MW and UHF max. 31 participants in accordance with Tab. 4 and receive broadcast in accordance with Tab. 4 can simultaneously differentiate their broadcast on UHF
- Participant n then reports / registers sleep mine hit mode for HGRM-S on participant n
