Как эффективно снизить уровень шума для встраиваемых промышленных сенсорных ПК?

В OAI, we know that as a professional industrial computer producer, the performance and stability of each product are directly related to the customer's production efficiency and user experience. Среди них, as the core component of the automation control system, noise control during the operation of the Embedded industrial touch PC is particularly important. Сегодня, OAI shares several practical noise reduction strategies to help your embedded industrial touch PCs run more quietly and efficiently.

1. Software noise reduction technology
Some embedded all-in-one computers are equipped with intelligent control systems, which can adjust the operating parameters of the equipment through software to achieve noise reduction effects. Например:
Dynamically adjust the fan speed, control the fan operation according to the equipment load, and reduce unnecessary noise.

Monitor and optimize the CPU operating frequency to reduce the noise level under high load.

2. Choose a suitable cooling system
The cooling system is one of the main sources of noise in embedded industrial touch PCs. Traditional fan cooling systems may generate loud noise, so when choosing equipment, you can consider the following ways to reduce noise:
Natural cooling: Например, OAI's D series embedded industrial touch PCs use natural cooling through the chassis vents, without fans, and with almost zero noise.

Безвентиляторная конструкция: Например, OAI's I series and U series embedded industrial touch PCs use built-in aluminum blocks or copper tubes for heat conduction, and are equipped with aluminum alloy back covers for heat dissipation, without fans, thereby greatly reducing noise.

Silent radiator: The principle of silent radiator is to increase the fan speed, speed up the airflow speed, increase the fan diameter, widen the air duct, increase the wind receiving area of the radiator, and increase the fan diameter at the same time.

3. Use vibration-damping materials
During the operation of the embedded industrial touch PC, the internal components may vibrate, which will cause noise. Using vibration-damping materials can effectively reduce vibration and noise. Specific measures include:
Use vibration-damping pads or vibration-damping glue inside the chassis.

Ensure that the hard disk and other mechanical parts are firmly fixed to avoid vibration transmission.

4. Regular maintenance and cleaning
During the long-term use of the equipment, dust and impurities will accumulate on the internal components, resulting in reduced cooling system efficiency and increased noise. Regular maintenance and cleaning are important steps to keep the embedded industrial touch PC running at low noise. Specific measures include:
If the embedded industrial touch PC has a built-in fan, clean the fan dust regularly.

Inspect and replace aged vibration-damping materials and fixtures.

5. Optimize the equipment installation environment
The equipment installation environment will also affect the noise level. Here are some ways to optimize the installation environment:
Keep away from noise sources: Install the embedded industrial touch PC away from other noise sources, such as large mechanical equipment.

Sound insulation treatment: Install sound insulation boards or sound insulation covers around the embedded industrial touch PC to reduce the interference of environmental noise.

Through the above methods, we can effectively reduce the noise of embedded industrial touch PCs in industrial environments, and improve the stability of equipment and the work efficiency of operators. If you have any questions or needs about noise reduction, please feel free to contact us.
