I. Development Trends of Industrial Control Computers
As the performance of commercial machines continues to improve, many industrial sites are adopting more cost-effective commercial equipment. This shift has brought about significant changes to the commercial machine market, leading to a greater preference for more user-friendly touchscreen tablets. Therefore, touchscreen tablets are gradually becoming the mainstream trend in industrial environments and an important component of industrial control equipment.
Compared with traditional controllers, Juhui industrial touch panel PCs have the following significant advantages:
1. The front panel is usually made of die-cast aluminum-magnesium alloy, with a protection level of NEMA Ip65, which is both sturdy and durable as well as lightweight.
2. The touch screen all-in-one industrial control computer adopts an integrated design, combining the host, LCD and touch screen into one unit, ensuring stable performance.
3. By integrating touchscreen functionality, workflows can be simplified, efficiency improved, and a more user-friendly operating experience achieved.
4. Industrial touch panel PCs are compact in size, making installation and maintenance simple and convenient.
5. Most industrial touch panel PCs adopt a fanless design, utilizing large-area finned aluminum blocks for heat dissipation, thereby reducing energy consumption and noise.
6. It has a beautiful and elegant appearance and a wide range of applications.
Industrial computers and commercial computers have always complemented and developed together. Technological progress is reflected in applications across various fields, and the two influence and promote each other.
II. What are the causes of industrial control computer malfunctions?
1. The temperature is not suitable.
Industrial PCs operate within a specific temperature range, ideally between 10-30℃. If the chassis temperature reaches 30℃, the internal hard drive temperature will be even higher. The following methods can help reduce this temperature: 1. Replace the CPU and hard drive fan with a higher-powered one to accelerate heat dissipation; 2. Install exhaust fans inside the chassis to increase airflow; 3. Install small axial fans on the rack housing the industrial PC; 4. Install air conditioning in the control room to lower the ambient temperature.
2. There are many inhalable particulate matter in the air.
The industrial environment is generally quite harsh. Many factories use raw materials that require powder processing, and with high airflow, industrial control computers (ICSCs) easily accumulate large amounts of particulate matter and dust. This can cause localized overheating and damage to the hardware. This problem frequently occurs around the cooling fans of the CPU, power supply, hard drive, and graphics card. In areas with light dust accumulation, and where normal production allows, timed dust blowing can be used. In areas with heavy dust accumulation, dust filter cloths can be placed at the ventilation openings of the IC case and cleaned regularly.
3. The ground shook violently.
In the industrial sector, large-scale equipment is common, and the operation of this equipment frequently causes ground vibrations. These vibrations can significantly damage the hard drives, optical drives, and floppy drives of industrial control computers. Hard drive manufacturing processes are becoming increasingly sophisticated, with current rotational speeds reaching 7200 RPM or even higher. In the massive data exchanges within automated control systems, hard drives operating at high speeds for extended periods are susceptible to vibration, leading to decreased read/write capabilities, slow head positioning, and even disk damage. Therefore, reducing vibration in the industrial control computer's environment is beneficial for hard drive protection. During engineering design, we can keep industrial control computers as far away from high-vibration-source work areas as possible. If the work location cannot be changed, we can also place foam or cushioning materials under the industrial control computer cabinets and enclosures to reduce the damage caused by vibration.
4. The power supply voltage fluctuates greatly and is prone to power outages.
Electricity is an indispensable resource today, and with rapid modernization, the demand for electricity is increasing daily. In the industrial sector, high-power equipment is abundant, leading to frequent power shortages, unstable voltage, and power outages. Industrial control computers (ICCs) often experience frequent system restarts due to unstable voltage and sudden power outages, potentially resulting in file loss and failure to boot. Furthermore, the read/write heads may malfunction due to inaccurate head return during power outages, causing disk failures. Therefore, the stability of the power supply in the ICC's operating environment is crucial for its proper functioning.
5. Unsuitable ambient humidity.
Inappropriate ambient humidity can negatively impact industrial control computers (ICCs). Since ICCs are composed of numerous electronic components, excessive humidity can cause short circuits and burn out the circuit boards; conversely, insufficient humidity can generate static electricity, which can also damage some electronic components. Therefore, both excessively high and low humidity pose potential threats to ICCs. For electrostatic discharge (ESD) protection, ICCs must have proper instrument grounding.
There are many factors that can cause industrial control computer (ICC) malfunctions, and we need to understand each one. Understanding the causes and consequences of malfunctions can greatly help prevent them from occurring. The five points mentioned above are five common causes, and we hope they can be helpful to you.
