Technical Field

[0001] The invention relates to the field of infrared simulation, and in particular to an infrared radiation simulation device. Background Art

[0002] With the advancement of technology and science, in the development and testing of new infrared guided weapon systems, especially medium and long-range guided weapons, not only the guidance of ground radar systems is needed, but also the guidance of space-based systems, such as satellites. For space-based infrared guidance and detection devices, since the size, weight and power characteristics of the target aircraft itself are quite different from the real target, and the space-based infrared guidance and detection system is not as flexible as the missile-borne infrared guidance and detection equipment, it takes a long time to prepare for capture and identification. Therefore, the traditional infrared enhancement method cannot achieve reliable observation and calibration. In order to achieve reliable observation of the space-based infrared guidance and detection system, and to have a more realistic simulation of the infrared characteristics of the target in the stratosphere, the infrared radiation intensity and infrared radiation enhancement time of the target aircraft are required.

[0003] At present, there are two commonly used infrared characteristic enhancement technologies: infrared blowtorches and infrared tracer tubes. However, the existing blowtorches, pods and tracer tube technologies all use the combustion method to increase the overall infrared radiation of the target aircraft, and cannot truly reflect the directional distribution characteristics of the infrared radiation intensity of the simulated target. In addition, the effect of infrared enhancement through the combustion method is limited. At the same time, the target aircraft basically flies in the stratosphere, the air is thin, and there is a risk of incomplete fuel combustion and failure to ignite. Moreover, pyrotechnics such as tracer tubes have a short burning time and cannot meet the preparation time for capture and identification by the space-based infrared guidance detection system. Existing technologies cannot solve the above problems. Summary of the invention

[0023] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0024] In the present invention, unless otherwise specified, the directional words used, such as "upper and lower", generally refer to the upper and lower parts of the device in normal use, and "inside and outside" refer to the outline of the device.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. Since the accompanying drawings are descriptions of the same device, the same reference numerals in the drawings represent the same components.

[0025] As described in the background art, in order to increase the intensity and enhancement time of the infrared radiation of the target drone, the existing technology is to enhance the infrared characteristics through an infrared torch and an infrared tracer tube. However, the existing infrared characteristic enhancement technology has limitations.

[0026] Therefore, the present invention provides an infrared radiation simulation device, which controls the generation of infrared radiation through circuits, and simulates the intensity and directional characteristics of infrared radiation through pulse width modulation technology and adjustment of reflective devices. This can effectively solve the above-mentioned problems and meet the low-cost and reliable observation requirements of space-based infrared guidance and detection systems.

[0027] The present invention provides an infrared radiation simulation device, comprising: a radiation cabin, in which an infrared radiation device is arranged, the infrared radiation device comprises an infrared radiator and a reflective device, the reflective device is arranged on a side of the infrared radiator that emits infrared radiation, and is used to generate and enhance infrared radiation; a battery cabin, in which a control circuit and a battery are arranged, the control circuit controls the infrared radiation device to emit radiation through a pulse modulation technology, and the battery is used to provide electrical energy for the infrared radiation device.

[0028] The specific examples of the present invention are further described in detail below with reference to the accompanying drawings.

[0029] In one embodiment of the present invention, referring to Figure 1 The infrared radiation simulation device includes two parts: a radiation cabin 10 and a battery cabin 20. The radiation cabin 10 is provided with an infrared radiation device for generating and enhancing infrared radiation; the battery cabin 20 is provided with a control circuit 210 and a battery 220. The control circuit 210 is used to control the infrared radiation device to emit radiation through a pulse modulation technology, and the battery 220 provides power for the infrared radiation device.

[0030] In one embodiment of the present disclosure, the external structure of the radiation cabin 10 is as follows: Figure 2 As shown, the radiation cabin 10 includes a hollow cavity formed by a spherical cover 101, a radiation cabin tube 102 and a base 103, and an infrared radiation device arranged inside the cavity. Specifically, the spherical cover 101 is connected to the radiation cabin tube 102 through a spherical cover clamp 104, and the radiation cabin tube 102 is connected to the base 103 located at the bottom of the radiation cabin tube 102 through screws 105.

[0031] In some embodiments, the ball cover may be a magnesium fluoride ball cover, and the screw may be a temperature-resistant screw.

[0032] The radiation cabin 10 is provided with an infrared radiation device, combined with Figure 1-Figure 4 , the infrared radiation device includes an infrared radiator 110, a reflective device 120, a heat energy converter 130 and a temperature sensor 140. The heat energy converter 130 is connected to the infrared radiator 110, and is used to obtain electrical energy from the battery 220 and convert the electrical energy into thermal energy according to the signal of the control circuit 210; the infrared radiator 110 is used to generate infrared radiation according to the thermal energy, the reflective device 120 is used to enhance the infrared radiation and control the direction of the infrared radiation, and the temperature sensor 140 is respectively connected to the heat energy converter 130 and the infrared radiator 110, and is used to transmit the temperature information of the infrared radiation device to the control circuit 210, so as to ensure that the infrared radiator 110 operates within a safe and efficient working range and prevent overheating or insufficient radiation.

[0033] exist Figure 1In the illustrated embodiment, the heat energy converter 130 includes a resistance wire of an iron-chromium alloy material. When heated by the current emitted by the control circuit 210, the iron-chromium alloy resistance wire can generate heat energy, and the temperature rises rapidly, thereby emitting infrared radiation of a specific band. The iron-chromium alloy has a high resistivity and good high-temperature stability, and can respond quickly under pulse width modulation (PWM) control to achieve precise control of the infrared radiation intensity. The fast response characteristic allows the system to adjust the infrared radiation intensity in a short time and simulate different target radiation characteristics.

[0034] In one embodiment of the present invention, the infrared radiator 110 is a ceramic infrared radiator, which serves as a base or supporting material of the infrared radiator, such as Figure 2-Figure 3 As shown, specifically, the infrared radiator 110 is composed of a conical infrared radiator located in the ball cover 101 and a cylindrical infrared radiator located in the radiation chamber 102, a fixing stud 106 is arranged between the two, and a hollow lead cavity 107 is arranged at the center of the infrared radiator 110 for wrapping and fixing the iron-chromium alloy resistance wire to provide structural stability and thermal management. Ceramic materials have excellent high temperature resistance and good thermal conductivity, and are low in cost. They are a low-cost infrared radiation generating material suitable for large-scale manufacturing. In some other embodiments, other different materials can also be used as the base material, and the present invention is not limited to this.

[0035] In some embodiments, the surface of the ceramic infrared radiator is coated with a thermal radiation coating, the main function of which is to improve the radiation efficiency and make the temperature distribution of the infrared radiator more uniform. The thermal radiation coating helps optimize the heat transfer and radiation characteristics, and can increase the intensity and stability of infrared radiation. In different embodiments, different thermal radiation coatings can be selected based on different uses or application scenarios. Common coating materials include silicon carbide, iron oxide, aluminum oxide, etc., and the present invention is not limited to this.

[0036] During operation, the control circuit 210 is connected to the heat energy converter 130 through a high temperature resistant electrical connection line, and an adjustable current is provided to the heat energy converter 130 through the PWM technology to control the heating of the iron-chromium alloy resistance wire, thereby controlling the intensity of the infrared radiation. After receiving the control signal, the heat energy converter 130 converts the electrical energy into thermal energy and transfers the thermal energy to the infrared radiator 110. The heat generated by the iron-chromium alloy resistance wire is transferred to the thermal radiation coating through the ceramic substrate. The thermal radiation coating emits infrared radiation of a specific band at high temperature. The emitted infrared wavelength is determined by the selection of the coating material and the working temperature.

[0037] In some embodiments, the control circuit 210 can adjust the duty cycle of the PWM signal to accurately control the average value of the current and adjust the temperature of the resistor, thereby achieving accurate control and fine adjustment of the infrared radiation intensity. A high duty cycle corresponds to a higher temperature and stronger infrared radiation, while a low duty cycle is the opposite.

[0038] In a specific embodiment of the present invention, Figure 1 As shown, a heat insulation device 150 is also provided in the radiation chamber cavity to prevent heat loss of the infrared radiation device; and to prevent heat from being transferred to the battery chamber 20 and affecting its normal operation. Figure 1 , Figure 3 and Figure 4 The thermal insulation device includes an integrated thermal insulation pad and a thermal insulation cone. The thermal insulation device 150 is arranged outside the infrared radiator 110. Specifically, the thermal insulation pad is fixed to the inner wall of the radiation chamber 102 through an upper ring sleeve 108, and is used to surround the infrared radiator 110 in the radiation chamber 102. The thermal insulation cone is arranged in the spherical cover 101, and is used to surround the infrared radiator 110 in the spherical cover 101.

[0039] In some embodiments, the material of the thermal insulation device includes aluminum silicate.

[0040] Continue to refer to Figure 1 In one embodiment of the present invention, the reflective device 120 includes a concave mirror, on which an infrared reflective coating is provided, for focusing the infrared radiation emitted by the infrared radiator 110, thereby realizing reflection and enhancement of the infrared radiation. After the infrared radiation is generated, it can be reflected and enhanced by the reflective device 120 to ensure that the infrared radiation meets the simulation requirements, such as the intensity distribution and directional characteristics of the infrared radiation of the target drone, thereby realizing the simulation of the intensity and directional characteristics of the infrared radiation of the target drone.

[0041] In some embodiments, the reflective device may be an optical lens or a reflector, which is mounted on the front end of the ceramic substrate and connected to the substrate through a mechanical fixing or adjustable mechanism. During operation, the reflective device can adjust the direction and distribution of infrared radiation as needed to simulate different target radiation characteristics; at the same time, the position and angle of the reflective device can be precisely adjusted through mechanical or electrical control to achieve fine control of the radiation direction to ensure the accuracy of optical adjustment.

[0042] In one embodiment of the present invention, in addition to the control circuit 210 and the battery 220, the battery compartment 20 further includes: a wireless communication device 230, a position information device 240 and a working state storage device 250, wherein the battery 220 is a solid-state battery. During operation, the infrared radiation simulation device is arranged on the target drone, wherein the control circuit 210 is used to control the working mode of the infrared radiation device according to the set requirements, such as pulse width modulation, etc.; the battery 220 provides power support for the entire system to ensure the stable operation of the infrared radiation and control system; the wireless communication device 230 is used to perform wireless data transmission and control with the outside world; the position information device 240 is used to feed back the position information of the target drone to the control circuit 210; the working state storage device 250 is used to store the working state of the infrared radiation simulation device according to the signal sent by the control circuit 210, including data such as radiation intensity and temperature.

[0043] In a specific embodiment, Figure 5 As shown, the battery compartment 20 also includes a radiation compartment interface 201, a charging interface 202, a temperature sensor interface 203 and a cooling fan 204. Specifically, during the generation and maintenance of infrared radiation, the temperature sensor 140 monitors in real time and transmits real-time temperature data to the control circuit 210 through an electrical connection line connected to the temperature sensor interface 203 to achieve temperature feedback. The control circuit 210 is connected to the radiation compartment through the radiation compartment interface. After receiving the temperature data, the control circuit 210 dynamically adjusts the PWM signal according to the feedback data to achieve precise control of the direction and intensity of the infrared radiation, thereby changing the working state of the infrared radiation simulation device, ensuring the stability and accuracy of the infrared radiation simulation device, and storing the working state in the working state storage device 250. The wireless communication device 230, the position information device 240 and the working state storage device 250 ensure remote control and data recording of the infrared radiation simulation device, and improve the reliability and operability of the infrared radiation simulation device.

[0044] In some embodiments, the battery compartment further includes an output control switch and an output fuse.
