Description

Technical Field

[0001] The present invention relates to a multi-laser gun simulation training system implemented based on time marking, and also relates to a control method for a multi-laser gun simulation training system implemented based on time marking. Background Art

[0002] Traditional live ammunition target shooting requires consumption of ammunition, has relatively high danger, and requires professional personnel to participate in guidance. At the same time, the equipment deployment requires a relatively large site, so the operation cost is relatively high. Using lasers for target shooting has high safety and high precision. Therefore, laser gun simulation shooting is increasingly applied to various occasions such as national defense education, student military training, enterprise military training, shooting experience activities in military exhibition halls, and entertainment.

[0003] The existing laser gun simulation shooting systems in the form of images on the market mainly have the following two forms:

[0004] The first form is that the laser gun shoots at a projection image, and the camera collects the landing points of the laser gun shooting at the projection image to judge the shooting result. The disadvantage of this method is that since the beam of the laser gun cannot be recognized by the camera photographing information for the gun number, only one laser gun can be trained in one scene, and the situation of multiple people shooting together in one scene cannot be simulated.

[0005] The second form is an improvement based on the first form, which is a multi-laser gun form. The wavelengths of the laser beams emitted by each laser gun are all different, and each laser gun corresponds to a camera. Each camera can only collect the landing points of the laser gun corresponding to it shooting at the projection image through a filter to judge the shooting results of each laser gun. The disadvantage of this method is that it still does not break away from the situation that one laser gun in the first form needs to correspond to one camera. During processing, each laser gun and each camera have specific requirements, which is not conducive to expanding multi-person simulation training. In one scene, when shooting at the projection image, the laser gun is often in a fixed position and cannot move, greatly limiting the flexibility of equipment use. Summary of the Invention

[0028] To solve the above - mentioned technical problems, the technical solution of the present invention is: a control method for a multi - laser - gun simulation training system based on time marking. When several laser guns are in the state of not pulling the trigger, it includes the following steps:

[0029] S1 - 1, control the scene image device through the main console to project or display the image of the target scene for simulation shooting;

[0030] S1 - 2, the time synchronization controller mechanism enters the working state, and the controller - side control unit, according to the timing of the built - in time timer, periodically sends the master time signal for forced synchronization through the controller - side communication module;

[0031] S1-3. Form a group of several laser guns and assign a gun ID to each laser gun;

[0032] Each laser gun is controlled by a gun-end control unit to turn the laser of the laser emission unit on and off. The gun-end control unit controls the laser emission units of several laser guns to emit lasers at staggered times;

[0033] The gun-end communication module receives the master control time signal in step S1-2, transmits the master control time signal to the gun-end control unit, and the gun-end control unit adjusts its built-in time timer to be consistent with the master control time signal;

[0034] S1-4. According to its built-in time timer, the image-end control unit controls the image-end time display mechanism to change the displayed time at the sampling time points with a set time interval;

[0035] According to its built-in time timer, the image-end control unit controls the camera to take a photo of the target scene at the sampling time points with a set time interval, and takes the time displayed by the image-end time display mechanism as part of the photo of the shooting target scene, and sends the photo of the shooting target scene to the main console through the image-end communication module;

[0036] The image-end communication module receives the master control time signal in step S1-2, transmits the master control time signal to the image-end control unit, and the image-end control unit adjusts its built-in time timer to be consistent with the master control time signal;

[0037] S1-5. The main console receives the photo of the shooting target scene sent in step S1-4;

[0038] When any one of several laser guns is in the state of pulling the trigger, the following steps are included:

[0039] S2-1. The gun-end control unit of the laser gun that pulls the trigger receives the trigger signal when pulling the trigger, and controls to send the gun-end time signal to the main console through the gun-end communication module;

[0042] S2-4. The main console determines whether there is a landing spot of the laser beam in the photo of the shooting target scene when the trigger is pulled in step S2-3. If there is no landing spot, it is parsed as a non-hit state; if there is a landing spot, it is a hit state. Parse the coordinate points of the landing spot in the photo of the shooting target scene, determine the shooting result, calculate the shooting result into the shooting gun ID determined in step S2-3. At the same time, the main console controls the scene image device to change the image of the target scene and display the bullet hole effect at the coordinate points corresponding to the landing spot.

[0043] As a preferred technical solution, step S1-5 is specifically that the communication module at the controller end receives the photo of the shooting target scene sent in step S1-4 and then transmits it to the main console.

[0044] As a preferred technical solution, the staggered firing in step S1-3 is specifically that at the sampling time points with a set time interval, only the laser emission unit of one laser gun is in the on state, and the other laser guns are in the off state; several laser guns form a group, and the laser emission units of each laser gun are in the on state in turn at the sampling time points, and this cycle repeats.

[0045] As a preferred technical solution, in step S1-4, the display format of the time displayed by the time display mechanism at the image end changes to binary display.

[0046] As a preferred technical solution, in step S2-1, the gun-end control unit also controls to send the gun ID information and the gun-end time signal to the main console through the gun-end communication module at the same time.

[0047] Due to the adoption of the above technical solution, using the time signal as an identifier, it overcomes the drawbacks in the prior art, realizes that for multiple laser guns, only one image acquisition device is needed to complete the acquisition and recognition of shooting information, saves the cost of equipment, and can flexibly adjust the number of laser guns, increasing the convenience of use. Moreover, it can accurately and quickly collect and identify information, giving users a better shooting experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] A trigger for triggering a trigger switch to generate a trigger signal when pulled;

[0069] A gun-side communication module for sending and receiving information;

[0070] A gun-side control unit with a built-in time timer. The gun-side communication module receives the master time signal sent by the controller-side communication module to synchronize the built-in time timer of the gun-side control unit; it is used to receive the trigger signal when the trigger is pulled and control the gun-side time signal to be sent to the main console 2 through the gun-side communication module;

[0071] A laser emission unit controlled by the gun-side control unit to turn the laser on and off; the gun-side control unit controls the laser emission units of a number of laser guns 4 to emit lasers at staggered times. At the sampling time points with a set time interval, only one laser gun 4's laser emission unit is in the on state, and the rest of the laser guns 4 are in the off state;

[0072] As Figure 8 and Figure 9 shown, the fifth part, the image acquisition device 5, includes

[0073] A camera 51 for taking pictures of the corresponding target scene at the sampling time points with a set time interval;

[0074] An image-side communication module for sending and receiving information, for receiving the master time signal for forced synchronization sent by the controller-side communication module, and sending the shooting target scene photos collected by the camera 51 to the main console 2;

[0075] An image-side time display mechanism 52 for displaying the time corresponding to the image acquisition device 5;

[0076] The image - side control unit, equipped with a built - in time timer, receives the master time signal for forced synchronization transmitted by the image - side communication module, synchronizes the built - in time timer of the image - side control unit, and controls the image - side time display mechanism 52 to display the time; at the sampling time points with a set time interval, it controls the camera 51 to take pictures of the target scene, and takes the time displayed by the image - side time display mechanism 52 as part of the pictures of the shooting target scene; and sends the pictures of the shooting target scene to the main console 2 through the image - side communication module.

[0077] The time synchronization controller mechanism 3 periodically sends the master time signal for forced synchronization to several laser guns 4 and the image acquisition device 5, so that the built - in time timers of several laser guns 4 and the image acquisition device 5 are synchronized, making the time synchronization controller mechanism 3, several laser guns 4, and the image acquisition device 5 in a time system, and avoiding the situation of inconsistent time caused by external factors.

[0078] The scene image device 1 is a projector that projects the target pattern onto the screen or an electronic screen displays the target pattern. The target pattern is a pattern for simulated shooting, which can be a circular target, a chest - shaped target, or various different scene pictures.

[0079] The controller - side communication module includes a controller - side wireless communication unit, which is used to periodically send the master time signal for forced synchronization outward in a wireless form, receive the gun - end time signal sent through the gun - side communication module, and receive the pictures of the shooting target scene sent through the image - side communication module; it also includes a main console connection serial port, which is used to transmit the gun - end time signal and the pictures of the shooting target scene received by the controller - side wireless communication unit to the main console 2; the controller - side communication module also serves as the communication module of the main console 2. The main console 2 can be a computer, a tablet, or other electronic devices with computing and storage capabilities, and can perform corresponding operations according to the control method of this embodiment. The main console 2 uses the controller - side communication module as the communication module, which can reduce costs. Of course, the main console 2 can also use a separate communication module to receive information. The main console connection serial port is a two - way communication unit, and the main console 2 can send signals outward through the main console connection serial port and the controller - side communication module.

[0080] The gun - side communication module is a gun - side wireless communication unit. The image - side communication module is an image - side wireless communication unit. Sending and / or receiving information wirelessly can greatly improve the convenience of use and facilitate position movement. The laser gun 4 also includes a sound - generating unit. The gun - end control unit controls the sound - generating unit to simulate the sound of gun shooting. The gun - end control unit receives the trigger signal when the trigger is pulled and controls the sound - generating unit to simulate the sound of gun shooting, making the simulation training effect more realistic.

[0081] The image - end time display mechanism 52 includes a number of arranged lamp beads, which facilitates the realization of binary counting by the lighting and extinguishing of the lamp beads, and is conducive to quickly and accurately identifying the time attached to the shooting target scene photo; the image - end time display mechanism 52 is arranged in front of the camera 51, which can ensure that when the camera 51 takes a photo of the stimulation picture, the lighting and extinguishing of each lamp bead can be taken as part of the picture together.

[0082] As Figure 5 shown, for a control method of a multi - laser - gun simulation training system based on time marking, when a number of laser guns 4 are in the state of not pulling the trigger, the following steps are included:

[0083] S1 - 1. Control the scene image device 1 through the main console 2 to project or display the image of the target scene for simulated shooting;

[0084] S1 - 2. The time synchronization controller mechanism 3 enters the working state. The controller - end control unit, according to the timing of its own time timer, regularly sends the master control time signal for forced synchronization through the controller - end communication module;

[0085] S1 - 3. Group a number of laser guns 4 and assign a gun ID to each laser gun 4;

[0086] Each laser gun 4 is controlled by the gun - end control unit to turn the laser of the laser emission unit on and off. The gun - end control unit controls the laser emission units of a number of laser guns 4 to emit lasers at staggered times;

[0087] The gun - end communication module receives the master control time signal in step S1 - 2, transmits the master control time signal to the gun - end control unit, and the gun - end control unit adjusts its own time timer to be consistent with the master control time signal;

[0088] S1 - 4. The image - end control unit, according to its own time timer, controls the image - end time display mechanism 52 to change the displayed time at the sampling time points set with a time interval;

[0089] The image - end control unit, according to its own time timer, at the sampling time points set with a time interval, controls the camera 51 to take a photo of the target scene, and takes the time displayed by the image - end time display mechanism 52 as part of the photo of the shooting target scene, and sends the photo of the shooting target scene to the main console 2 through the image - end communication module;

[0090] The image - end communication module receives the master control time signal in step S1 - 2, transmits the master control time signal to the image - end control unit, and the image - end control unit adjusts its own time timer to be consistent with the master control time signal;

[0091] S1 - 5. The main console 2 receives the photo of the shooting target scene sent in step S1 - 4;

[0092] When any one of a number of laser guns 4 is in the state of pulling the trigger, the following steps are included:

[0093] S2-1. The gun-end control unit of the laser gun 4 that pulls the trigger receives the trigger signal when the trigger is pulled, and controls to send the gun-end time signal to the main console 2 through the gun-end communication module;

[0094] S2-2. The main console 2 receives the gun-end time signal in step S2-1;

[0095] S2-3. The main console 2 identifies the time displayed by the image-end time display mechanism 52 included in the shooting target scene photo in step S1-5. When the time displayed by the image-end time display mechanism 52 is matched with the gun-end time signal, it is confirmed that the shooting target scene photo is the shooting target scene photo when the trigger is pulled, and at the same time, the shooting gun ID is confirmed;

[0096] S2-4. The main console 2 judges whether there is a landing spot of the laser beam in the shooting target scene photo when the trigger is pulled in step S2-3. If there is no landing spot, it is parsed as a non-hit state; if there is a landing spot, it is a hit state. Parse the coordinate points of the landing spot in the shooting target scene photo, determine the shooting result, calculate the shooting result into the shooting gun ID determined in step S2-3, and at the same time, the main console 2 controls the scene image device 1 to change the image of the target scene and display the bullet hole effect at the coordinate point corresponding to the landing spot.

[0097] Step S1-5 is specifically that the controller-end communication module receives the shooting target scene photo sent in step S1-4 and then transmits it to the main console 2.

[0098] The staggered emission in step S1-3 is specifically that at the sampling time points with a set time interval, only one laser emission unit of one laser gun 4 is in the lit state, and the rest of the laser guns 4 are in the off state; a number of laser guns 4 form a group, and the laser emission units of each laser gun 4 are in the lit state in turn at the sampling time points, and this cycle repeats.

[0099] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a number of laser guns 4 form a group and are assigned gun IDs, such as 01 / 02 / 03…, and the gun IDs are unique and non-repeating. At the sampling time points set at time intervals, only the laser emission unit of one laser gun 4 is in the on state, and the rest of the laser guns 4 are in the off state. For example, if there are 8 laser guns 4 in the whole group, at the first sampling time point, the laser gun 4 with gun ID 01 is in the on state, and the rest of the laser guns 4 are in the off state; at the second sampling time point, the laser gun 4 with gun ID 02 is in the on state, and the rest of the laser guns 4 are in the off state; …… at the eighth sampling time point, the laser gun 4 with gun ID 08 is in the on state, and the rest of the laser guns 4 are in the off state; at the ninth sampling time point, the laser gun 4 with gun ID 01 is in the on state, and the rest of the laser guns 4 are in the off state. The change of the laser gun 4 in the on state is ID01→ID02→ID03→ID04→ID05→ID06→ID07→ID08→ID01→ID02……, and at the sampling time points, the on state is cyclically displayed in sequence.

[0100] For this embodiment, the sampling time points of each part adopt the same time interval, and the time interval of the sampling time points can be set and changed as needed. When the time interval is smaller, the simulation effect of training is more realistic. For example, the time interval can be set to 1 / 800 second. The on and off states of the whole group of laser guns 4 change 800 times in one second, and the number of photos of the shooting target scene taken by the camera 51 is 800 per second. Since the time interval of the sampling time points is small enough, it gives the user the visual impression that the laser emission units of each laser gun 4 are always on simultaneously, and each laser gun 4 is always in the simulated aiming and shooting state. Through the technology of discrete sampling, this embodiment achieves a continuous effect, can identify the shooting of multiple laser guns 4 with one camera 51, and does not need to limit the fixed position of the laser guns 4.

[0101] In step S1-4, the display format of the time displayed by the image end time display mechanism 52 changes to binary display. The image end time display mechanism 52 uses a number of arranged lamp beads, and the on and off of the lamp beads represents the binary counting method. For example, if there are 8 lamp beads, at the first sampling time point, the 8 arranged lamp beads are "off off off off off off off on", which can be parsed as binary 00000001; at the second sampling time point, the 8 arranged lamp beads are "off off off off off off on off", which can be parsed as binary 00000010; ……. Using the binary counting method is beneficial for the main console 2 in step S2-3 to identify the time displayed by the image end time display mechanism 52 included in the shooting target scene photo.

[0102] In step S2-1, the gun-end control unit also controls the gun ID information and the gun-end time signal to be sent to the main console 2 through the gun-end communication module simultaneously. This can further accurately ensure that the shooting result is calculated into the shooting gun ID determined in step S2-3. The main console 2 can indirectly identify the gun ID through the gun-end time signal sent by the gun-end communication module. At the sampling time point, only the laser emission unit of one laser gun 4 is in the bright state. It can also be directly achieved through the gun ID information sent by the gun-end communication module. When the gun ID information and the gun-end time signal are used simultaneously, it can better ensure the accuracy of parsing.

[0103] The gun ID information and the gun-end time signal are transmitted according to the data protocol specification requirements of this embodiment to ensure that they can be effectively sent, received, and parsed.

[0104] The controller-end control unit, the gun-end control unit, and the image-end control unit all adopt single-chip microcomputers.

[0105] This embodiment uses the time signal as an identifier to achieve time synchronization. The time synchronization controller mechanism 3 regularly sends the master control time signal for forced synchronization to several laser guns 4 and image acquisition devices 5, so that several laser guns 4 and image acquisition devices 5 synchronize their built-in time timers, enabling the time synchronization controller mechanism 3, several laser guns 4, and image acquisition devices 5 to be in the same time system. This overcomes the drawbacks of the prior art and enables the collection and identification of shooting information to be completed with only one image acquisition device for multiple laser guns 4, saving the cost of equipment. Moreover, the number of laser guns 4 can be flexibly adjusted, increasing the convenience of use. In addition, information can be collected and identified accurately and quickly, providing a better shooting experience for users.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
