[0017] According to the utility model, the surface heating medium can be selected from any heating material that can achieve surface heating after being energized, including a rigid body with a surface conductive coating and / or a conductive surface coating and a flexible body that is conductive itself or has a conductive coating. For example, a rigid body with a surface conductive coating and / or a conductive surface coating can be, but not limited to, a building, a ship, an aircraft, a motor vehicle (including a rail train, a car, a tank), a human-shaped target plate (including a head, a chest and a half-body target plate), etc. that is entirely or partially coated with a surface conductive coating and / or a conductive surface coating; a flexible body with a surface coating can be, but not limited to, a woven fabric, paper and a non-woven fabric that is entirely or partially coated with a conductive coating; a flexible body that is conductive itself is selected from carbon fiber paper, carbon fiber cloth, etc. The conductive coating can be generated by coating and curing the surface of the target rigid body and the flexible body with a conductive slurry. Examples of the conductive slurry include silver paste, aluminum paste, carbon paste, etc. The conductive surface coating includes, but is not limited to, a prefabricated conductive film layer or the aforementioned self-conductive or conductive coated flexible body attached to the surface of the rigid body to form an electrically heatable film layer by pasting or the like.
[0018] According to the utility model, the electrode is used to connect the surface heating body with the heating power supply. Under the premise of being sufficient to achieve this purpose, the utility model has no restrictions on the material constituting the electrode. In specific implementation, the electrode is usually selected from copper, silver, aluminum and carbon paste electrodes. They can be commercially available products or prepared by any existing technology.
[0019] Generally, the electrode is in the form of a strip (or a belt) and is bonded to the surface heating body by pasting. For example, the electrode is made of a commercially available copper foil with a conductive adhesive backing, including the copper foil cut into an electrode strip adapted to the surface heating body as an electrode, and the copper electrode strip is pasted on two non-adjacent edges of the surface heating body by a conductive adhesive backing, which is the heating body electrode. For the plastic-sealed heating medium and electrode, a portion of the plastic film of the plastic-sealed electrode can be removed by removing it to form an electrode wiring hole for connection with the wire.
[0020] According to the utility model, the function of the adhesive layer is at least to make the plastic sealing film form a stable and close-fitting plastic cover on the surface heating body. Under the premise of being sufficient to achieve this purpose, the utility model has no particular restrictions on the adhesive used to form the adhesive layer. For example, the adhesive is selected from a heat-sensitive adhesive and a pressure-sensitive adhesive, and the adhesive can be a solution-type adhesive, an emulsion-type adhesive or a solid adhesive sheet.
[0021] In the utility model, the use of adhesive makes the production of the target body easier and the properties more stable.
[0022] According to the utility model, the plastic cover is formed by coating the surface heating body with a plastic sealing film combined with an adhesive, and its function includes insulating the surface heating medium in the surface heating body from the non-plastic sealing film layer and the environment.
[0023] When the rigid body is a surface heating body, in order to ensure the surface heating property of the surface heating body, when processing the surface conductive coating and / or conductive surface coating (surface heating medium) of the rigid body, generally, either the prefabricated conductive film layer or the aforementioned self-conductive or conductively coated flexible body (surface heating medium) is first subjected to the plastic sealing treatment described in the utility model; or the rigid body is subjected to surface insulation treatment, and then the prefabricated conductive film layer (surface heating medium) or the aforementioned self-conductive or conductively coated flexible body (surface heating medium) is attached to the insulating layer. In the latter case, the plastic sealing cover of the surface heating body includes covering the self-conductive (surface heating medium) or conductively coated flexible body (surface heating medium) attached to the insulating layer with a plastic sealing film and forming the plastic sealing together with the insulating layer.
[0024] According to the utility model, the non-plastic sealing film is a film that can shield the infrared light and heat radiation generated during the heating process of the surface heating medium. The choice of the non-plastic sealing film of the utility model is not particularly limited as long as it is sufficient to shield the infrared light and heat radiation generated during the heating process of the surface heating medium.
[0025] Preferably, the non-plastic film is selected from metal and metal-containing films (or foils); the preferred metal is selected from one or more of aluminum, silver, copper, and gold. For example, a metal foil selected from copper, gold, silver, or aluminum, or a gold-stamping paper. Examples of gold-stamping paper include various gold-stamping papers prepared from electrochemical aluminum. When the non-plastic film is used, the metal foil or gold-stamping paper can be pasted to the designated part of the plastic cover by pasting; or the metal paste or carbon paste of the metal can be applied or printed on the designated part of the plastic cover to form.
[0026] Generally, when infrared night vision goggles are used to observe the target in working state, the whole target is a bright area. The utility model changes the brightness of the target under night vision by setting a film layer that has a shielding effect on infrared light. The indicative feature of the target is to display the part of the target that needs to be highlighted through this change in brightness. For example, the bull's eye in the head target, chest and half-body target; the highlighting of the island in the surface ship, etc. If necessary, multiple non-plastic film layer areas can be set on the plastic package to meet the requirements of highlighting multiple parts on the same target.
[0027] According to the utility model, the sizes and specifications of various infrared targets are not specifically limited under the premise of meeting the needs of target shooting. Generally, the sizes and specifications of various infrared targets can be made consistent with the corresponding white light targets (targets used under sunlight). For example:
[0028] In a specific embodiment, the target body is a head target.

[0034] The size of the head target, chest target and half-body target, as well as the position, size and shape of the bull's eye, can be consistent with conventional white light targets such as head target, chest target and half-body target, or can be specially designed as required. The present invention does not impose any special restrictions on this.
[0035] The following further describes the present invention by taking the head target as an example. It should be understood that the specific implementation methods described therein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0036] Figure 1a , Figure 1b The utility model is a schematic diagram of an infrared target body (head target) provided by the utility model.
[0037] like Figure 1a The infrared target body shown includes carbon fiber paper 1 as a surface heating medium, an electrode 2, a plastic film 4, a non-plastic film layer 5 set as the center of the target, and an electrode wiring hole 6.
[0038] Figure 1b for Figure 1a The schematic view of the AA section includes a carbon fiber paper 1 as a surface heating medium, an electrode 2, an adhesive layer 3, a plastic film 4 and a non-plastic film layer 5 set as a target.
[0039] The preparation method thereof comprises:
[0040] (1) preparing a surface heating body consisting of a surface heating medium 1 and an electrode 2;
[0041] (2) sealing the surface heating element prepared in step (1) with a plastic sealing film in combination with an adhesive;
[0042] (3) A non-plastic sealing film layer 5 is pasted or printed on the plastic cover 4.
[0043] According to the above method, the step (2) includes forming a laminate of the surface heating element, adhesive and plastic film, and then preferably includes a pressing step.
[0044] Among them, the surface heating medium 1 is a commercially available carbon fiber paper with a brand name of NL-10; the electrode 2 is arranged on two non-adjacent long sides of the carbon fiber paper by pasting with a conductive adhesive backing, and the electrode 2 is a commercially available copper foil with a conductive adhesive backing with a brand name of T1; the adhesive layer 3 uses a liquid pressure-sensitive adhesive; the plastic cover 4 uses a PI modified high-temperature co-extruded film, and the non-plastic sealing film layer 5 is an aluminum foil.
[0045] like Figure 1a , Figure 1b The target shown is electrically heated when in use, and the heating temperature is controlled to be 2°C higher than the ambient temperature. The infrared radiation of the target is observed by an infrared mirror under night vision conditions (also known as infrared thermal imaging). The target is distinguished from other bright areas by the dark area where the non-plastic film is set.
[0046] Figure 2 Another infrared head target provided by the utility model, Figure 2 The difference from FIG. 1 is that two non-plastic covers 7 are provided on the target body as non-bull's-center as shown in FIG. 1 , so that the target body seen through an infrared lens in a night vision environment is visually similar to a traditional head target.
[0047] According to the utility model, the infrared target system includes a power supply.
[0048] Under the premise that it is sufficient to meet the requirements of safe heating, there is no special restriction on the working voltage of the heating body or the infrared target in the utility model. Generally, any power supply that can be provided by the prior art can be used as a power supply to power the infrared target. Including power supplies whose output voltage matches the working voltage of the infrared target, which can directly power the target; also including power supplies that are transformed into power supplies that match the working voltage of the infrared target through any existing transformation technology to power the target system. For example, the power supplies that can power the target of the utility model include DC power supplies and AC power. The DC power supply includes but is not limited to batteries or battery packs. For example, the battery can be a storage battery, a lithium battery, a chromium battery, a nickel-chromium battery, etc.; the AC power includes but is not limited to AC power with a voltage of AC220V.
[0049] Generally, the sheet resistance of the surface heating medium in the present invention is 5 to 40,000 ohms (the resistivity of these surface heating media is usually greater than 0.1 μΩ·m), and the operating voltage is 3.7 to 220V.
[0050] When the target is a head target, a chest target or a half-body target, the square resistance of the surface heating medium is preferably 5 to 30 ohms; the preferred working temperature of the infrared target is -40°C to 50°C; and the preferred working voltage of the infrared target is 12 to 24V.
[0051] Figure 3This is a flowchart of the use of an infrared target system provided by the utility model. Figure 3 The infrared target system works by supplying power to the control box, which then supplies power to the target. After the system is powered on, the operator (e.g., the shooter) controls the output voltage of the control box to supply power to the target according to the ambient temperature, and the target is heated and generates observable infrared radiation.
[0052] Taking the head target, chest target, and half-body target system as an example, the power supply may be, but is not limited to, the following methods:
[0053] The power source is a DC12V battery (a mobile power source, such as a DC12V lithium battery or a lead-acid battery). Figure 4 A configuration block diagram of a control box is given. The control box with this configuration can be used to step up and modulate the DC12V battery, so that the DC voltage can be adjusted within the range of 12V to 24V.
[0054] according to Figure 4 The configuration of the control box includes DC / DC, switch, and output voltage control. Among them, the arrangement of DC / DC, switch, and output voltage control satisfies: when the target needs 12V power supply for heating, the power supply directly heats the connected target after the switch is turned on; when the target needs 12V~24V power supply for heating, the power supply is converted into 12V~24V power supply through DC / DC and output voltage control to heat the connected target after the switch is turned on.
[0055] Alternatively, the power source is a DC24V battery pack (a mobile power source, such as two DC12V lithium battery packs connected in series). Figure 5 A configuration block diagram of a control box is given. The control box with this configuration can be used to step up and modulate the DC24V battery, so that the DC voltage can be adjusted within the range of 12V to 24V.
[0056] according to Figure 5 The configuration of the control box includes switches and output voltage control. The arrangement of the switches and output voltage control satisfies: when the target needs 24V power supply for heating, the power supply directly heats the connected target after the switch is turned on; when the target needs 12V~24V power supply for heating, the power supply is converted to 12V~24V power supply through output voltage control after the switch is turned on to heat the connected target.
[0057] Alternatively, the power source is an alternating current power source (such as AC 220V mains power). Figure 6 A configuration block diagram of a control box is given. The control box with this configuration can be used to step up and modulate the AC220V mains power, so that the AC voltage is converted into a DC voltage that is adjustable within the range of 12V to 24V.
[0058] according to Figure 6The configuration of the control box includes a switching power supply, a switch, and an output voltage control. Among them, the arrangement of the switching power supply, the switch, and the output voltage control satisfies: after the switch is turned on, the power is converted into a 12V~24V DC voltage by the switching power supply and the output voltage control to heat the connected target paper.
[0059] In the present invention, the DC / DC, switching power supply and switch are commonly used components in circuit control. It is easy for those skilled in the art to configure the DC / DC, switching power supply and switch according to actual needs, which will not be described in detail here.
[0060] The output voltage control includes a resistor, a capacitor, a switch voltage regulator controller and a field effect transistor combination to control the output voltage value. Figure 4 , Figure 5 and Figure 6 In the embodiment, the switching regulator controller is LTC3789, which is a buck-boost switching regulator controller. The output voltage is controlled by adjusting the resistance value, thereby realizing differential temperature control of the target paper. In actual control, the output voltage is controlled to vary within the range of 12V to 24V according to the heating needs.
[0061] According to the utility model, the control box may include a thermometer to test and display the ambient temperature around the target system.
[0062] According to the utility model, a remote control power switch can be arranged in the control box, so as to turn off the target body heating at any time during training breaks, thereby reducing power consumption.
[0063] according to Figure 3 The method of using the infrared target system includes using a power supply to supply power to a control box, and the control box supplies power to a target. After the system is powered on, the operator (e.g., a shooter) supplies power to the target through voltage output control according to the ambient temperature, and when the required voltage value is reached, the infrared target is heated, and the target is heated and generates observable infrared radiation.
[0064] The infrared image formed by the target body in the target system provided by the utility model after heating is clear, stable, reliable, and has good outdoor long-distance visibility. In particular, the bull's eye is simple in design and has strong resistance to repeated strikes. In addition, the control box in the target system provided by the utility model can be flexibly configured according to the actual convenient power supply. When used in conjunction with the target body of the utility model, it is particularly suitable for live-fire target shooting training in the field under night vision conditions for troops.
