Description

Technical Field

[0001] This invention relates to the field of new energy equipment monitoring and environmental control technology, specifically to a switch temperature control device suitable for changing the heat dissipation and regulating temperature in a centralized monitoring system for new energy. Background Technology

[0002] In centralized monitoring systems for new energy sources, switches, as core communication equipment, operate long-term in high-temperature, high-humidity, and dusty environments. Existing devices generally employ fan cooling or fixed ventilation structures to maintain temperature balance, with some devices incorporating temperature sensors for start-stop control to achieve intermittent cooling. While these solutions are effective in typical indoor environments, they struggle to respond to real-time temperature changes in complex outdoor conditions. Chinese patent CN207688362U discloses a warehouse with constant temperature control, employing temperature sensors, a motor, and movable fan-shaped baffles to regulate airflow and achieve constant temperature control. This maintains a stable temperature within a closed space and has a reasonable structure; however, its regulation method primarily relies on centralized cooling and fixed air ducts, lacking the ability to rapidly dissipate heat from high-temperature equipment and failing to consider the impact of dust and moisture on the ventilation system.

[0003] In centralized monitoring systems for new energy sources, the internal components of switches are densely packed and generate significant heat. Inadequate heat dissipation can easily lead to communication instability or component aging. Existing structures often use a single air duct with fixed, non-adjustable dust filters. Dust accumulation increases resistance, reduces heat dissipation performance, and prevents automatic cleaning. Even after equipment shutdown, ventilation openings remain exposed, making them susceptible to dust and moisture corrosion, resulting in insufficient protection. Current technology lacks a device that can automatically adjust the air inlet opening based on temperature changes and automatically close the air duct when not in operation. It also lacks self-cleaning and maintenance functions for dustproof components. This problem is even more pronounced in the high-temperature, dusty environment of new energy power plants, necessitating an adaptive temperature control device that balances heat dissipation efficiency and dustproof sealing to improve the long-term operational stability and environmental adaptability of the system.

[0056] 1. Signal acquisition circuit The signal acquisition circuit synchronously samples environmental status data to obtain temperature and humidity data.

[0057] 2. Data Preprocessing After data acquisition, the signal acquisition circuit transmits the data to the data processing unit for preprocessing. Preprocessing includes noise reduction filtering, normalization transformation, and dynamic deviation calculation. The steps are as follows: Noise reduction filtering: The acquired temperature and humidity signals are denoised to reduce data fluctuations caused by sensor errors and environmental changes.

[0058] Normalization transformation: The processed temperature and humidity data are normalized to ensure that the data are calculated within the same order of magnitude. 72.1℃ is normalized to 0.8, and 85.4%RH is normalized to 0.85.

[0059] Dynamic deviation calculation: The temperature and humidity deviation is calculated by comparing the real-time collected data with the set thresholds. The set temperature threshold is 70℃, with a deviation of 2.1℃; the set humidity threshold is 80%RH, with a deviation of 5.4%RH.

[0060] 3. Temperature and humidity coupling algorithm calculation The preprocessed temperature and humidity signals are input into a temperature and humidity coupling algorithm to jointly calculate the temperature adjustment coefficient and humidity correction coefficient. The steps are as follows: Temperature adjustment factor: Calculated based on temperature deviation. If the deviation is 2.1℃, the temperature adjustment factor is 0.85. Humidity correction factor: Calculated based on humidity deviation. If the humidity deviation is 5.4%RH, the humidity correction factor is 1.1.

[0061] 4. Adjust the control signal output The temperature regulation coefficient and humidity correction coefficient are jointly calculated to generate a regulation control signal, which controls the regulation intensity of the heat dissipation system and the air inlet opening. The calculation is as follows: Heat dissipation regulation intensity: determined by the temperature regulation coefficient. When the temperature regulation coefficient is 0.85, the regulation intensity of the heat dissipation system is 80%. Air duct opening ratio: determined by the humidity correction coefficient. When the humidity correction coefficient is 1.1, the air duct opening ratio will be adjusted to 70%.

[0062] 5. Adjustment effect By calculating and adjusting control signals, the system responds to changes in temperature and humidity in real time and precisely controls the heat dissipation system. When the internal temperature of the equipment reaches 72.1℃ and the humidity is 85.4%RH, the system will adjust the air duct opening to 70% and adjust the heat dissipation intensity to 80% to ensure that the equipment temperature is kept within the ideal range.
