[0023] Compared with the prior art, the scheme has the following beneficial effects: far infrared radiation is part of the electromagnetic spectrum of sunlight, and its wavelength range is usually between 4μm and 1000μm. It has high energy, can be transmitted without passing through a medium, has low heat loss, can transfer energy to objects more directly and efficiently, reduces energy waste, and quickly generates heat energy after being absorbed by an object. After the object is heated, it drives the surrounding environment to heat up, so that high energy conversion can be achieved with low power consumption, which can save energy and achieve the goal of low-carbon energy saving. This scheme realizes anti-condensation and dehumidification inside the electrical cabinet by means of far-infrared optical principle radiation heating, combined with humidity monitoring and control technology. It mainly conducts correlation analysis based on the changes in temperature and humidity in the environment to understand the relationship between them. In areas where condensation may occur, it ensures that the ambient temperature is maintained at a relatively high level so that the moisture in the air is not easy to condense; adjusts the humidity in the air to prevent excessive humidity and control condensation under humid environmental conditions; through the monitoring and control system, the equipment is automatically adjusted to work and stop according to real-time temperature and humidity data to change environmental conditions to prevent condensation. Based on temperature and humidity data, a logic judgment algorithm is disclosed, which realizes an intelligent control logic. This environmentally friendly anti-condensation solution reduces energy consumption and reduces dependence on chemical antifreeze and other chemical substances, thereby reducing the negative impact on the environment. Through far-infrared radiation technology, it is possible to reduce energy consumption while maintaining the surface temperature of the equipment, achieve high efficiency and energy saving, and improve the efficiency of anti-condensation; no chemical substances are required to reduce the impact on the environment, and through far-infrared radiation technology, condensation can be reliably prevented from forming; humidity sensing and adaptive control technology are used to enable the system to intelligently adjust according to actual humidity conditions to maintain the best operating state; it is suitable for various equipment surfaces, including but not limited to power equipment, electronic equipment, optical instruments, etc.; it can be migrated between different equipment to improve the adaptability of the model on new equipment.
