At present, many users on the market have purchased CNC cutting machines equipped with industrial control operating systems. Compared with traditional control systems, the most significant feature of industrial control systems is the ability to achieve on-site process design and graphic compilation, enabling cutting process design and cutting processing to be completed simultaneously on site. Wuhan Lanxun has purchased industrial control operating systems for multiple gantry CNC cutting machines. Below, we will mainly summarize some common problems and solutions of industrial control operating systems, hoping to provide reference and help for users:

1. The environmental humidity is not suitable. CNC cutting machine cutting method - choose the appropriate cutting method based on the material being cut. The oxygen tube is red and can only be used for oxygen and cannot be used for other gases; Acetylene pipes are black, and it is prohibited to switch between two types of rubber pipes. Industrial control computers are mainly composed of integrated circuits of numerous electronic components, and their insulation performance is closely related to environmental humidity. Excessive humidity can easily cause a short circuit in the circuit board (current not passing through electrical appliances, directly connecting to the two poles of the power supply) and burn it out; If the humidity is too low, it is easy to generate static electricity (a type of static charge), which can also break down some electronic components. Therefore, excessive or insufficient humidity can pose potential threats to industrial computers. On the issue of electrostatic protection, it is required that our industrial control computer must have a good grounding. It is worth noting that the grounding electrode of the industrial control computer is different from the lightning protection grounding in civil engineering. The grounding electrode should be located three meters away from the control room, and a vertical grounding electrode made of galvanized angle steel should be used 1700mm below the outdoor floor. The number of grounding electrodes should meet the requirement that the grounding resistance (Chinese name: resistor) is less than 1 ohm (tested with a shaking table during backfilling). Then, 40 × 40 × 4 galvanized flat steel should be reliably welded to the grounding body (each welding point should be carefully rust proofed), and a 25mm copper cable should be connected to the system grounding terminal and the industrial control computer grounding point inside the building. This can effectively reduce the harm caused by static electricity.

2. There are many inhalable particles in the air. Numerical control cutting machine is a high-tech precision tool, and its use in the machining industry is not very extensive. There are many things to pay attention to when using a CNC flame cutting machine, and using an oxygen tube is one of the things that needs to be noted. Below are some precautions for the oxygen tube of a CNC flame cutting machine, which will be briefly explained to users. Many factories require powdered raw materials for processing, and coupled with high external air flow and dust, it is easy for industrial computers to accumulate a large amount of sticky dust, causing local high temperatures and hardware damage. This situation often occurs around cooling fans such as CPUs, power supplies, hard drives, graphics cards, etc. In areas with light dust accumulation, timed dust blowing can be used when normal production allows. In areas with severe dust accumulation, dust filter gauze can be placed at the ventilation area of the industrial control chassis and cleaned regularly.

3. The power supply voltage fluctuates greatly and is prone to power outages. With the rapid development of industry and daily life, the demand for electricity is also increasing day by day. Many areas have insufficient power supply, unstable voltage, and are prone to power outages. Unstable voltage and sudden power outages can cause frequent system restarts, resulting in the loss of system files and the inability to start normally; The magnetic head that is performing read and write operations may sometimes cause inaccurate return of the head due to power outages, resulting in disk failures in industrial control computers. Therefore, the stability of the power supply in the working environment of the industrial computer is related to whether the industrial computer works normally or not. We can use regulated power supply and UPS uninterruptible power supply for protection. The specific equipment selection depends on the load power and the required working time.

4. Industrial control computers have long working hours. Numerical control cutting machine is a high-tech precision tool, and its use in the machining industry is not very extensive. Due to the needs of normal production, some factories' industrial control systems require long working hours, which poses a huge challenge to the operation system of industrial control computers. According to Microsoft's operating system runtime report, Microsoft claims that its Windows 2000 and later operating systems can support long-term work. However, in actual operation, after running for more than a week, the disk will accumulate a large amount of data fragments during the massive data exchange process, which can easily cause disk logical bad lanes, read and write errors, and slow system operation and startup. So, if production permits, industrial computers can be restarted and disk fragmentation can be scheduled to reduce disk errors caused by long-term work. The restart time can be determined according to the amount of data processed by the industrial computer and the production situation. It is not mandatory and requires readers to explore slowly. Based on the actual experience of Wuhan Lanxun, restarting and organizing an industrial computer once a standard month (30 days) can reduce the probability of disk errors.

5. There is a strong ground vibration sensation. In the production of mechanical manufacturing factories, physical displacement actions such as dragging and vibration not only bring huge noise (decibels (dB)), but also the vibration caused by equipment operation can cause huge damage to industrial computer disks, optical drives, and floppy drives. In the large-scale data exchange in automation control systems, disks that operate at high speeds for long periods of time are prone to a decrease in disk read and write capabilities, slow head positioning, and even disk damage due to vibrations transmitted to the disks. Therefore, reducing environmental vibrations in industrial control computers is beneficial for protecting disks. We can try to keep the industrial control computer as far away from the work site with large seismic sources as possible during engineering design; If the workplace cannot be changed, we can also place sponges and buffering objects under the industrial control cabinets and boxes to reduce the harm caused by vibration.

6. The internal temperature of the industrial computer is too high. In environments that require long-term high-temperature operation, computer components are prone to aging and the frequency of hard disk failures is also higher. This requires the CNC cutting machine operators in the factory to closely monitor the temperature of the chassis and try to keep the temperature of the industrial computer between 10-30 degrees Celsius (℃). Temperatures that are too high or too low are not suitable for protecting the hard drive. If the chassis temperature reaches 30 degrees Celsius, the temperature of the internal hard drive will reach 40 degrees Celsius or higher. We can simply modify our industrial control computer to achieve the effect of reducing the ambient temperature.

6.1 Replace high-power CP

U. Hard disk fan (hard disk fan should be fixed and not installed on the hard disk firmware rack to prevent hard disk vibration caused by fan rotation) accelerates heat dissipation.

6.2 Install a fan inside the chassis to draw air out of the chassis and increase air convection;

6.3 Install air conditioning in the control room to reduce the temperature of the space.
