Description

Technical Field

[0001] The present invention belongs to the technical field of real-soldier simulation, and in particular relates to a digital real-soldier combat system for medium and long-distance communication and a method thereof. Background Art

[0002] To meet the needs of military modernization and intelligent training, traditional laser-based live-fire engagement systems are gradually evolving towards digitalization. Digitalized live-fire engagement systems provide more accurate trajectory simulations, more intelligent damage models, and adjudication mechanisms. Because of their digital implementation, large amounts of data transmission are essential, making a reliable and stable communication solution paramount. Traditional digital live-fire engagement systems based on 4G modules require the installation of communication base stations and servers, which are large and complex. Furthermore, data transmission can fail when the signal is unstable. Using laser mode as a backup in this situation also presents significant drawbacks. At medium and long ranges, the small beam spot is difficult to hit, while at close range, the beam spot's scattering spreads widely, making it impractical for realistic shooting.

[0003] Furthermore, the traditional 4G communication digital live-fire combat system has a very high cost for setting up an environment for small and medium-sized exercises. In actual application, a low-cost, reliable communication backup solution is needed. Summary of the Invention

[0004] Purpose of the invention: The purpose of the present invention is to address the deficiencies of the existing technology and provide a digital real-life combat system and method for medium and long-distance communication, which has low cost and reliable communication and is suitable for medium and long-distance, small and medium-scale simulated combat.

[0005] Technical solution: The digital real-soldier combat system for medium and long-distance communication of the present invention comprises: a plurality of groups of real-soldier terminals, each group of real-soldier terminals having an individual soldier master control and a weapon master control interconnected with each other; the individual soldier master control is installed on the individual soldier, and is integrated with a first microprocessor, an RTK positioning module, a first communication module, a second communication module, a display module and a first sensor module, the RTK positioning module is used to collect the position information of the individual soldier, and the first sensor module is used to collect the status information of the individual soldier; the weapon master control is installed on the weapon, and is integrated with a second microprocessor, an RTK positioning module, a second communication module and a second sensor module, the RTK positioning module is used to collect the position information of the weapon, the second sensor module is used to collect the status information of the weapon, and the second communication module of the weapon master control is connected to the weapon. The second communication module of the individual soldier master control is connected, and the second microprocessor is used to obtain the position information and status information of the weapon and send it to the first microprocessor; the individual soldier master controls of multiple groups of actual soldier terminals communicate with each other in a point-to-point or broadcast form through the first communication module, and the individual soldier master control of one group of actual soldier terminals can obtain the position information and status information of the individual soldiers and weapons in this group through the first microprocessor, and can perform ballistic information solution and hit feedback based on the weapon position information and status information transmitted by other groups of individual soldier master controls; the guidance and control terminal, the guidance and control terminal is wirelessly connected to the first communication modules of multiple groups of the actual soldier master controls through the first communication module, and is used to obtain the position information, status information and hit feedback of the individual soldiers and weapons of each group of actual soldier terminals, and make decisions on the individual soldier master control and weapon master control based on the hit feedback.

[0006] To further improve the above technical solution, the first communication module is a LoRa data radio, and the guidance and control terminal forms a network connection with the LoRa data radios of multiple individual soldier master controls through the LoRa data radio to perform point-to-point communication. The individual soldier master control periodically uploads its own individual soldier and weapon position information and status information to the guidance and control terminal through the LoRa data radio; multiple individual soldier master controls are connected through the LoRa data transmission platform to perform point-to-point or broadcast data transmission; the second communication module is any one of Bluetooth, Zigbee, and WiFi communication modules, and the individual soldier master control and the weapon master control form short-range communication.

[0007] Furthermore, the first sensing module is a six-axis sensor, which is used to collect the posture information of a single soldier; the second sensing module is a nine-axis sensor or an electronic compass, which is used to collect the direction and angle of fire of the weapon; the status information of the single soldier includes the health status and posture of the single soldier; the status information of the weapon includes the type of weapon, the type of bullet, and the direction and angle of fire.

[0008] Furthermore, after receiving the firing event of other individual soldier master controllers, the individual soldier master controller combines the position information and status information of the individual soldiers and weapons of both sides, calculates the ballistic information through the first microprocessor, determines whether the firing party can hit itself, and updates its own status according to the judgment result.

[0009] Furthermore, the firing event includes the weapon position, firing direction and angle, firing range, firing rate, weapon type and firing timestamp of the firing party's actual soldier terminal.

[0010] Furthermore, after receiving the firing event, the individual soldier master controller calculates the distance between the weapon master controller and the individual soldier using the Harversine formula, and determines whether the firing party can hit the individual soldier based on the azimuth, elevation, and altitude of both parties, including the following steps:

[0011] (1) The single-soldier master receives the firing event through the LoRa data radio, including: the firing party's weapon range, the firing party's latitude value lat2, and the firing party's longitude value lon2.

[0012] (2) Use the Haversine formula to calculate the distance d between the player and the shooter.

[0013]

[0014] Where: R is the radius of the earth, lat1 is the latitude of the own side, lat2 is the latitude of the firing side, lon1 is the longitude of the own side, and lon2 is the longitude of the firing side;

[0015] (3) Comparing distance and range,

[0016] Compare the calculated distance d with the weapon range transmitted by the firing party: if d is within the weapon range, proceed to the next step; if d is beyond the weapon range, it is determined that the hit was not made and the judgment ends;

[0017] (4) Calculate the azimuth angle yaw2,

[0018] Calculate the azimuth of the firing party relative to the own party ,

[0019]

[0020] Among them, pi is 3.141592653;

[0021] The target's nine-axis sensor acquires the magnetic north angle as yaw1, queries the local magnetic variation, and compensates for it, obtaining the compensated angle yaw3. Compare the compensated angle yaw3 with the firing target's azimuth yaw2. If the difference between the two is within the allowable error range, proceed to the next step. If not, the target is deemed a miss and the evaluation ends.

[0022] Obtain the altitude difference pitch2 between the two sides and the collected altitude angle pitch1, and compare them. If the difference is within the allowable error range, it is determined that the firing party can hit itself. If it is not within the error range, it is determined that it cannot hit itself, and the judgment ends.

[0023] Furthermore, the control terminal records and saves all firing events during the exercise, and first locks the weapon of the individual master controller who receives the death status, making it lose the ability to engage in combat.

[0024] Furthermore, the individual soldier master control is also provided with an ultrasonic sensor or an infrared light sensor. Only when the firing party's individual soldier master control transmits the firing event to the target individual soldier master control through the ultrasonic sensor or the infrared light sensor, the target individual soldier master control will turn on the lora data transmission radio to receive data to analyze the firing event.

[0025] Since all soldiers on the battlefield are subject to attack, if each soldier's main control unit is enabled to receive external firing event broadcast data, the traffic will be too large, the bandwidth will be insufficient, and the data will be non-targeted. Therefore, the default state is to not receive external data. When the firing party attacks the targeted soldier, the firing event is transmitted to the target soldier. At this time, the target soldier senses that he is being attacked and starts receiving data, ensuring the uniqueness of the target at the time of firing and reducing data traffic pressure.

[0026] Furthermore, the weapon main control is directly integrated into the simulated firearm or mounted on the outside of the firearm, and simulates the firing effects, including the simulation of recoil, sound and fire, through the second microprocessor.

[0027] A method for conducting a combat exercise using the above-mentioned digital live-fire combat system for medium- and long-range communications includes the following steps:

[0028] S1: Before the exercise begins, the soldier master controller and the weapon master controller need to be bound one-to-one via short-range wireless communication to ensure normal communication between them;

[0029] S2: Calibrate the nine-axis gyroscope or electronic compass on the weapon's main control unit to ensure its azimuth accuracy meets the standard for use.

[0030] S3: The control terminal sends the exercise parameters. The exercise begins. After receiving the parameters, the individual soldier's main control unit periodically uploads its own status, including its health, party, posture, time, position, as well as the type of weapon main control unit, bullet type, weapon firing direction and angle, and weapon position.

[0031] S4: Determine the engagement firing event. If no engagement switch event occurs, the individual master controller continues to periodically upload its own status.

[0032] S5: If a battle or firefight occurs, the individual master controller will broadcast the firing event to the guide master controller and other individual master controllers.

[0033] This includes weapon position, firing angle, range, rate of fire, weapon type, and firing timestamp;

[0034] S6: The guidance and control terminal receives and records the firing event, and the other individual master controllers receive the event and calculate whether they can hit themselves and whether they can cause damage based on the information carried in the event;

[0035] S7: If a single soldier's main controller dies, the control terminal will receive its death status and lock the weapon's main controller bound to it, making it unable to engage in combat.

[0036] S8: Wait until the exercise time is up or the control terminal issues an exercise end instruction, and the exercise ends.

[0037] Beneficial effects: Compared with the existing technology, the advantages of the present invention are: the present invention uses digital communication to replace laser bullets. The transmitted data includes the firing speed, acquisition position and firing angle of various caliber ammunition. The relative position between the attacking party and the attacked party is calculated through these data. Combined with the performance data of the bullet, such as speed, weight and other information, the microprocessor starts to calculate the ballistic simulation, which can simulate ammunition of various calibers and easily realize the calculation of ballistics, making the weapon strike effect closer to reality and the overall live-fire exercise battlefield closer to actual combat. The combination of high-precision positioning and gyroscope solves the ballistic model and damage model; this digital live-fire combat system greatly improves the training effect during military combat exercises. It is compatible with various terrain environments, supports a variety of equipment, simulates real combat scenes, and can virtualize troops. It uses advanced technical means to provide soldiers with an efficient, practical and safe training method, effectively improving the army's combat capability, tactical level and command quality.

[0040] Figure 3 It is a communication solution for the medium and long-range communication digital live-fire combat system when firing. DETAILED DESCRIPTION

[0041] The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.

[0042] Example 1: Figure 1The digital live-fire combat system shown is composed of live-fire terminals and guidance and control terminals. The live-fire terminals are composed of individual soldier master control and weapon master control.

[0043] The individual soldier main control can be installed on the individual soldier's back armor or helmet. It integrates the RTK positioning module to collect accurate position information, the serial port screen to display the real-time status, the six-axis sensor to calculate the individual soldier terminal posture, and the Lora data transmission radio for data transmission. The first microprocessor is responsible for solving the ballistic information and providing hit feedback.

[0044] The weapon controller can be installed in a variety of ways, either directly inside the simulated firearm or externally. It integrates a nine-axis sensor or electronic compass to measure the muzzle's firing angle, an RTK positioning module to collect precise weapon position information, and a second microprocessor to simulate firing effects and collect data processing. Firing effects include recoil, sound, and flash simulation.

[0045] Communication between the weapon master control and the individual soldier master control can be achieved through short-range, stable wireless communication methods such as Bluetooth, Zigbee, and WiFi. These transmission methods offer advantages such as low latency, low packet loss, and stable point-to-point connections. Information collected by the weapon master control is sent to the individual soldier master control via short-range wireless communication. The individual soldier master control then processes the information and transmits it to the guidance and control terminal or other individual soldier master control via a LoRa data radio.

[0046] The LoRa data radio is integrated into both the control terminal and the individual master control, responsible for medium- and long-distance data communications. Once networked, it can communicate point-to-point and broadcast. Leveraging its unique characteristics, the individual master control can periodically upload status and weapon information to the control terminal. The control terminal can also make point-to-point decisions and set other commands for specific individual master controls. Communication between individual master controls can be transmitted point-to-point or in broadcast form. The transmitted information includes the sender's weapon firing position, weapon firing direction, weapon range, rate of fire, weapon type, and firing timestamp.

[0047] The carrier of the guidance and control terminal can be a PC or tablet. Its main functions are to display and record the current battle situation, issue ruling orders, control the entire battle situation, and display the status information of the individual soldier master control and weapon master control in real time. The status information includes the individual soldier's health status (alive, injured or dead, etc.), the individual soldier's position, posture, weapon position, weapon firing direction and angle, and other information.

[0048] The final decision of this communication solution is made by the MCU of the individual master control end. When a soldier master control receives the broadcast firing information through the Lora data radio, it determines whether it can hit itself based on the weapon range, weapon position and direction transmitted by the opponent. The judgment process is as follows:

[0049] Calculate the distance d between the coordinates of the firing party and the coordinates of the own party according to the Harversine formula.

[0050]

[0051] Among them, R is the radius of the earth, lat1 is the latitude value of the own side, lat2 is the latitude value of the firing side, lon1 is the longitude value of the own side, and lon2 is the longitude value of the firing side.

[0052] The calculated distance d is compared with the weapon range transmitted by the firing party. If the distance between the two is within the range, the azimuth is determined, including:

[0053] Calculate the azimuth of the firing party relative to the own party ,

[0054]

[0055] Among them, pi is 3.141592653,

[0056] The magnetic north angle collected by the player's nine-axis sensor is obtained as yaw1. The local magnetic variation is queried and compensated to obtain the compensated angle yaw3. The compensated angle yaw3 is compared with the firing side's azimuth yaw2. If the difference between the two is within the allowable error range, the next step is continued. If not, the hit is determined to be unsuccessful and the judgment ends.

[0057] The pitch2 obtained by the RTK positioning module is compared with the altitude angle pitch1 collected by the firing party's nine-axis or electronic compass. If the difference is within the error range, it can be determined that the firing hit the target.

[0058] like Figure 2 As shown in the figure, this is a system flow chart of this example:

[0059] S1: Before the exercise begins, the soldier master controller and the weapon master controller need to be bound one-to-one via short-range wireless communication methods such as Bluetooth, ZigEee, and WiFi to ensure normal communication between them;

[0060] S2: Soldiers conduct a self-test of the module and calibrate the weapon's nine-axis gyroscope or electronic compass to ensure its azimuth accuracy meets operational standards.

[0061] S3: The control terminal sends exercise parameters. The exercise begins. After receiving the parameters, the individual soldier master controller periodically uploads its own status, including its health, party, posture, time, position, weapon type, bullet type, weapon direction and angle, and weapon position.

[0062] S4: Determine the engagement firing event. If no engagement switch event occurs, the individual master controller continues to periodically upload its own status.

[0063] S5: If an engagement or firefight occurs, the individual master controller broadcasts the firing event to the guide master controller and other individual master controllers. The event includes the azimuth and elevation angles of the own weapon, the RTK position of the weapon, and the timestamp.

[0064] The S6 guidance and control terminal receives and records the firing event, and other individual master controllers receive the event and calculate whether they can be hit and whether they can cause damage based on the information carried in the event.

[0065] S7: If a soldier dies, the control terminal receives the death status and first locks the weapon, rendering the soldier incapable of engagement. The soldier then performs a simulated effect, such as emitting smoke from a smoke canister or making a voice announcement.

[0066] S8: Wait for the exercise time to expire or for the control center to issue an exercise end instruction, and the exercise ends.

[0067] like Figure 3 As shown in the figure, in this medium- and long-range communication digital live-fire engagement system, when the individual master controller sends a firing event, it broadcasts the data. The other individual master controllers can choose to enable or disable reception. If they enable reception, all firing events must be processed, which increases the data processing pressure on the MCU. Here, ultrasonic sensors or infrared and invisible light are used to transmit firing events. The individual master controller in the firing direction only enables reception when it receives the beacon, and disables reception at other times. This significantly reduces the load on the individual master controller MCU.

[0068] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
