The whole industrial computer is a computer used for industrial production machine control. The value-added industrial computer is designed for 30,000 hours of trouble-free continuous operation. That is to say, the industrial computer supports continuous work for a long time, which is more efficient than ordinary computers. Suitable for harsh environments, such as temperature, dust, etc. In order to use the industrial computer correctly, let's take a look at the precautions in the use of the industrial computer. Note that the installation of the industrial computer should be reasonable. The whole industrial computer must be installed reasonably and compliantly. First of all, the installation of the chassis and the hard disks of the main board bottom plate should be horizontal or vertical, which is in line with the principle of gravity. Secondly, it is necessary to pay attention to the reliability of various connections, especially in the vibration environment, try to do some checks regularly to see whether the various connections are reliable, otherwise the equipment will not operate normally or even damage the equipment due to poor contact. Be sure to replace the fan filter regularly.
The fan of the IPC is the air intake and ventilation port of the entire chassis. Therefore, it is very important to replace the fan filter regularly. Note that the requirements for the fan filter are not only to filter dust, but also to keep the airflow flowing into and out of the chassis smoothly. , otherwise the heat dissipation eddy current in the chassis will not work properly, and the chassis will not be able to dissipate heat properly, which may cause serious consequences. Pay attention to protect the hard disk during use. Some of the hard disks of the whole industrial computer are mechanical parts, which are relatively fragile, so more attention should be paid to protection during use. First, because the hard disk is a magnetic medium, vibration during use should be avoided in particular, and secondly, the hard disk is read and written. Do not force the power off during the process, otherwise it will damage the hard disk or even cause the hard disk to be scrapped and can no longer be used. The characteristics of the industrial computer that are different from commercial computers are: due to the influence of the working environment and working time, it is required to have stronger shock resistance, anti-magnetic, dust-proof, shock-resistant performance and low power consumption than commercial computers. Long-term stability In order to ensure the normal performance of the well-known industrial computer, the above precautions should be done by every user.
Analysis and handling of the failure of the industrial computer: Make sure that the power cable and VGA cable of the display are properly connected to the host; the power indicator on the bottom plate can be lit normally, CLEAR CMOS, re-plug and clean the memory gold finger. Unplug the hard disk data cable and PCI card and gradually clean or remove it; failure symptoms: PC card cannot be used; whether there is a PC device in the device manager; pull out the P card and use an eraser to wipe the gold finger and replace the PCl slot; clean Motherboard gold finger; replace the same type of PG| card; replace the bottom plate. Symptoms: The computer cannot receive any input, the computer screen freezes, or the monitor blue screen.
Hardware reasons: poor heat dissipation: the heat of the CPU, graphics card and hard disk cannot be dissipated in time (especially the CPU); motherboard failure: the components on the motherboard are easily damaged by the ambient temperature, humidity, and dust, resulting in poor signal transmission. Stable, need to be cleaned and then exchanged; memory failure: memory stick loose, gold fingers oxidized, naturally damaged; hard disk failure: if there are bad sectors or bad sectors in the hard disk, software reasons: system files are lost or deleted by mistake; virus occupation System resources, and corrupt executable files or programs; too little free space on the hard disk.
Analysis and processing of industrial computer: too many programs are loaded at startup; a certain program takes too long to start; insufficient hard disk space; illegal shutdown, resulting in disk self-checking, which consumes a lot of time; virus, virus program is opened and occupied A large proportion of CP resources are used, so that the system has no chance to start the normal program at all; restart caused by software installation; system restart caused by virus; restart caused by poor heat dissipation of the machine and high temperature; Restart caused by bad hardware such as memory, hard disk, motherboard, etc.; EMC electromagnetic interference. Dust: Since the computer case is not completely sealed, and the static electricity generated when it works has the effect of vacuuming, it is most likely to be contaminated with dust. When the dust adheres to the surface of the dust filter, it will cause the chassis to not be ventilated, the heat dissipation will not be smooth, and even cause a short circuit of the motherboard circuit in severe cases. Vibration and impact on the hard disk, the precise original components of the motherboard are damaged, and the point is dropped. Static electricity has always been the deadly killer of precision components. Among industrial control chassis accessories, the most concentrated place for components is of course the motherboard. Due to the accumulation of static electricity, when the accumulation reaches a certain level, there will be an instantaneous partial high-voltage discharge, and the huge energy is enough to burn the "squeamish" components and the B0S on the motherboard.
IPC maintenance suggestions:
◆ Regularly clean up system garbage, backup system and important data;
◆Remove dust in the chassis of the whole machine regularly and clean the golden fingers of the machine;
◆Ensure a good power supply environment and avoid damage to the board;
◆Ensure that the whole machine is well grounded and the working environment is good
