Description

Technical Field

[0001] The present invention belongs to the technical field of simulating infrared thermal radiation, and in particular relates to a heat source system and a simulation method thereof for simulating infrared thermal radiation characteristics of a shelter. Background Art

[0002] Simulating infrared thermal radiation characteristics is an important part of modern science and technology, especially in climate change research, target identification, remote sensing monitoring, medical diagnosis and industrial detection. In remote sensing monitoring, simulated infrared thermal radiation characteristics can help interpret the temperature information of ground objects, and then be used in vegetation monitoring, urban heat island effect research and hydrological monitoring. In other fields of application, accurate simulation of the target's infrared thermal radiation plays a vital role in target identification and concealment.

[0003] The simulation of infrared thermal radiation characteristics of medical shelters is a relatively complex physical process involving multiple factors and steps, which has a major impact on the design and function maintenance of medical shelters. In a specific environment, a large number of electronic devices will be equipped inside the shelters. The operation of these devices will not only generate heat, but also affect the temperature distribution in the cabin, which in turn affects the infrared thermal radiation characteristics of the shelters. In medical shelters, understanding and controlling the internal thermal environment is crucial for patient recovery and the normal operation of medical equipment. In applications in other fields, accurate simulation of infrared thermal radiation characteristics can help concealment and target identification of medical shelters. By using a temperature control system to control the temperature of the shelters to simulate the infrared characteristics of the shelters, they can be used as false targets to confuse the enemy and reduce economic losses.

[0004] Moreover, during the actual use of the shelter, it is easily affected by factors such as heat convection, heat radiation, and heat conduction. For example, the heat emitted by electronic equipment when working, the heat generated by the staff themselves, the heat transmitted to the interior of the shelter by outdoor solar radiation, and the external environment temperature, weather conditions and other factors interfere and affect, making it difficult to control the temperature of the shelter within the normal working temperature range under a specific environment. In addition, the infrared camouflage characteristics of the shelter are directly related to the temperature. Therefore, in order to better study the imitation between the infrared characteristics of the shelter and the use environment, it is necessary and important to accurately control the temperature of the shelter.

[0005] Therefore, there is an urgent need for a heat source system targeting the infrared thermal radiation characteristics of the cabin to solve the problem of studying the infrared thermal radiation characteristics of the cabin under laboratory conditions.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a heat source system for simulating the infrared thermal radiation characteristics of a square cabin. The temperature of the square cabin is controlled by controlling the heating device to simulate the different working states of the square cabin in different use environments, thereby realizing the infrared characteristic simulation of the square cabin.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] On the one hand, the present invention provides a heat source system for simulating the infrared thermal radiation characteristics of a square cabin, including a square cabin, wherein a heat source system for regulating the temperature of the square cabin to simulate the infrared thermal radiation characteristics of the square cabin is arranged in the square cabin, the heat source system includes a hot air system arranged in the square cabin and used to absorb external air and heat it into hot air for discharge out of the square cabin, and a heating unit attached to the inner wall of the square cabin and used to heat the cabin body, the cabin body is also provided with an inlet and an outlet, and temperature sensors are attached to the inner walls of the inlet and the hot air system, and the hot air system, the heating unit and the temperature sensor are all controlled by a controller.

[0010] Specifically, the hot air system includes an air inlet arranged on the side of the cabin body, and the air inlet is connected to the air inlet fan and the high-temperature heater arranged in the cabin through an air intake duct.

[0011] Preferably, the air intake volume of the air intake fan is set to 1700m 3 / h, ensuring that it can provide sufficient air volume for smoke exhaust to achieve a realistic simulation effect; further, the speed of the air intake fan can be controlled by the controller, so that the air intake volume can be set to 0-1700m 3 / h to simulate different environments and working conditions.

The temperature sensors at the smoke exhaust port and the window smoke exhaust hole monitor the temperature and feed the temperature back to the controller, so that the exhaust temperature is finally consistent with the set working temperature. The exhaust temperature can be set between the ambient temperature and 600°C. Usually the exhaust temperature is set between 150°C and 400°C, which can better simulate the exhaust temperature of a diesel engine.

[0017] Specifically, the heating material of the high-temperature heater includes one of a carbon ceramic two-dimensional high-temperature heating material, a carbon fiber planar heating material, and a graphene planar heating material; it integrates heating and heat dissipation, has the characteristics of high heat dissipation power and high heat dissipation efficiency, and can meet the requirements of large space, high temperature, and rapid heating; the use of surface heating can better overcome the problem that the cabin wall panels are usually made of rust-proof aluminum plates and filled with flame-retardant materials in the middle. The thermal conductivity and emissivity of these materials have an important influence on the thermal radiation characteristics.

[0018] Specifically, a plurality of heating units are attached to the inner walls of the front and back sides of the cabin, and the plurality of heating units are evenly attached to the inner walls of the front or back sides.

[0020] Specifically, a control panel is attached to the outer wall of the side of the cabin, and a controller is arranged in the control panel.

[0021] On the other hand, the present invention provides a method for simulating the heat source system for simulating the infrared thermal radiation characteristics of the shelter as described above, and the specific method is as follows:

[0022] First, according to the cabin type to be simulated, the hot air system and the heating unit are turned on by the controller;

[0023] Then the temperature sensor detects the temperature data of the hot air when it is discharged from the cabin and the inner wall of the inlet and outlet, and feeds it back to the controller;

[0024] Finally, the controller adjusts the heating temperature of the hot air system and the heating unit according to the temperature data obtained through feedback, and finally makes the exhaust temperature of the hot air system and the cabin temperature consistent with the working temperature of the cabin type to be simulated, meeting the requirements of simulating the infrared thermal radiation characteristics of the cabin.

[0025] Specifically, by collecting the infrared characteristics of various cabins, the infrared characteristics of different cabins can be simulated through the control of the intelligent temperature controller, and the radiation characteristics can be conveniently adjusted dynamically for scientific research.

[0026] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:
