The development of my country's industrial computer has passed through multiple stages from inception, to widespread use. At present, with the development of computer technology, communication technology, microelectronic technology and control technology, industrial computers have achieved good development effects in terms of technology, environmental trends and applications. By the end of this year, the trend range of my country's industrial computer situation has exceeded 10 billion, and it occupies a relatively high proportion of all industrial control industries. It is worth mentioning that the industrial computer with the current domestic environment trend is dominated by domestic brands, which to a certain level is just a reflection of the domestic brand's innovation ability and product service failure to obtain state trend recognition. Intelligence is the perfect example.
The development trend of China's industrial computer environment has been very fast in the past ten years, which is an opportunity for us.
The technical principle of the industrial computer is similar to that of the general computer, and the structure is similar, but the emphasis of the industrial computer is the stability of its work. The industrial computer generally works in a relatively sinister environment, and the requirements for environmental temperature, humidity, supply and voltage, stability, and ventilation performance are relatively high, but the operating conditions often fail to meet the requirements, and the industrial computer is also prone to obstacles. Problems detected by the hardware can also be changed in real time. Once the disk is damaged, a large number of recorded data will be lost, and the control software will be damaged, which cannot be repaired in a short time, and the control of the controlled parameters will become unstable, which often brings huge economic losses.
Obstructive signs and appearances:
After the industrial computer runs for a long time, (long time refers to: including the time of continuous operation for a standard month of 30 days/24 hours and above), a large amount of dust accumulates in the chassis, and the temperature of the chassis is relatively high. Usually, everything is normal without shutting down. Once the power supply is insufficient or it is necessary to shut down urgently, the control system can easily find that the disk cannot be started, the system cannot be loaded, and it is in the landing screen for a long time.
Obstructing analysis and solving the essentials:
The reasons for causing the disk failure are the most, here we can roughly divide the quality problems of the disk itself and the problems caused by the working environment.
As for the quality of the disk itself, we cannot be deeply concerned. Only when we first do the control system, we can choose to purchase a hard disk with a better quality and brand, and we can also use Scandisk, Norton Disk Doctor and other software to check the appearance of the disk. If we can predict the quality and health of hard drives, this will give us time to select hard drives and back up important data.
The obstacles caused by the situation are more common in the following aspects:
1. The industrial computer has a long working time. Due to the necessity of normal manufacturing, the industrial control system of some manufacturers takes a long time to work, which brings great training to the industrial computer control system.
2. The temperature inside the industrial computer is too high. In the case of high temperature operation for a long time, the components of the computer are prone to aging, and the frequency of hard disk failure is also higher.
3. The humidity is not suitable. The industrial computer is mainly composed of integrated circuits of many electronic components, and its insulation performance has a great relationship with the environmental humidity. If the humidity is too large, it will easily become a short circuit of the circuit board and destroy it; if the humidity is too small, it will easily generate static electricity, and it will also break down one-sided electronic components.
4. Great earthquakes are felt. Many manufacturers require the motor to produce drag, touch and other physical displacement movements, which not only bring huge noise, but also the touch brought by the mechanical operation will bring huge obstacles to the disk, optical drive, and floppy drive of the industrial computer.
5. There are many inhalable particles in the atmosphere. Most of the raw materials of many manufacturers need to be processed with powder materials. In addition, the external atmosphere is very active and there is a lot of sand and dust. A large amount of sticky dust is easily accumulated in the industrial computer. destruction. This situation occurs mostly around cooling fans such as CPU, power supply, hard disk, and graphics card.
6. The power supply voltage fluctuates greatly and is prone to power outages. With the rapid development of industry and life, the necessary amount of electricity is also increasing day by day. In many areas, the power supply is insufficient, the voltage is unstable, and the power failure is easy to occur. Unstable voltage and sudden power failure cause the system to restart frequently, and the system files are easily lost and cannot be started normally; the magnetic head that is performing the read and write operations may occasionally become the head return prohibition due to the power failure, which will cause the disk failure of the industrial computer. . Therefore, the consolidation of the power supply in the work environment of the industrial computer is related to whether the work of the industrial computer is normal or not. We can use regulated power supply and UPS uninterrupted power supply for protection. The specific building selection depends on the size of the load power and the duration of the work.
Regardless of the risks caused by the disk failure of the industrial computer, ensuring its safety is a problem that our industrial control personnel should pay attention to. Only when we take careful precautions beforehand can the industrial computer be stable and run smoothly. The author adopts the above-mentioned facilities in practical work, which effectively avoids the disk failure of the industrial computer, and can reduce the repair time of the failure from the original several hours to a few minutes, providing guarantee for the normal production.
