People who have inquired a little about industrial computers can also know the difference in the application of industrial computers. The classification of industrial computers is also very rich, including embedded industrial computers, rack-mounted industrial computers, wall-mounted industrial computers, industrial tablet computers, and so on. Well, before we ask about industrial computers, we must first clarify the point of view of industrial computers. Industrial computers are aliased as industrial computers, industrial computers, or industrial computers. In short, they are computers specially designed for the industry.
Hot, what kind of characteristics does an industrial computer have after all? According to the details of our industrial computer, the editor rectified it for friends.
If you are currently using an industrial computer, or you are planning to use an industrial computer, you must know that the industrial computer will often run in a more sinister environment, and the data security requirements will also be higher, so the industrial computer usually Special plans such as reinforcement, dust-proof, moisture-proof, erosion-proof, and radiation-proof will be carried out, and the industrial site usually has violent alarm, excessive dust, and high electromagnetic field force disturbance. Continuous homework. Therefore, the industrial computer has extremely high requirements for environmental habits.
At the same time, the industrial computer has very high requirements for scalability, and the design of the interface needs to meet specific external structures, so in most cases, the industrial computer needs to be individually customized to meet the needs. Therefore, the industrial computer must have the following characteristics in comparison with the usual computer:
1. The ability to work continuously for a long time is required.
2. The chassis adopts steel structure, which has high anti-magnetic, dust-proof and anti-strike ability.
3. There is a special power supply in the chassis, and the power supply has strong anti-interference ability.
4. There is a special bottom plate in the chassis, and there are PCI and ISA slots on the bottom plate.
5. The industrial computer usually chooses an example chassis that is easy to install.
Brief introduction to the diagnostic methods of common obstacles of industrial computer
IPC obstruction 1. After the power is turned on, the power indicator light on the backplane of the IPC will turn off once it is on, and it cannot be powered on:
1. Check whether there are foreign objects such as screws in the chassis, which may cause a short circuit.
2. Observe whether the relevant power cords are reversed, resulting in a short circuit to ground. Use the alternative method again to replace the power supply, motherboard, backplane and other structures.
Prevents turning on the power supply of the industrial computer twice, but there is no feedback:
1. Check whether the power outlet has electricity and is connected to the computer normally;
2. Open the case cover to check whether the power supply is connected to the computer backplane or mainboard, whether the connection between the backplane and the mainboard is loose, whether the backplane or mainboard is powered on, and whether the ATX power supply is wired incorrectly;
3. Check whether the computer power supply can work normally, and whether the display of the industrial computer and the host computer are continuously normal;
4. Whether the alarm is activated when the memory stick is unplugged;
5. Change the CPU or motherboard.
Obstruction 3. After the industrial computer is turned on, the main board self-checking sound is heard, but there is nothing on the display:
1. Check whether the display is consistent with the host;
2. Clear the CMOS (or the configuration is faulty) or change the BIOS;
3. Insert another performance card to check whether it can perform normally;
4. Change the CPU board (mainboard integrated graphics card) or display.
4. After the industrial computer is powered on, the power supply is normal, and the motherboard does not respond:
Start to remove the peripheral card and the connected building to see if it can be started. If not, remove the memory to see if it alarms, and then check whether the CPU is normal or not. Finally, replace the main board and check whether the main board is normal.
