The industrial computer hardware constitutes the equipment foundation of the industrial control machine system. To truly realize the computer control of the production process, we must provide the corresponding computer software for the hardware to realize the control task. Software is the program system of an industrial computer, which can be divided into three parts: system software, tool software and application software.
1. System software: used to manage the resources of an industrial computer, and to provide services to users in a simple form. It includes a real-time multi-task operating system, a bootstrap program, and a scheduling and execution program. In addition to real-time multi-task operating systems, MS-DOS, especially Windows software, is also often used.
2. Tool software: it is the auxiliary software for technical operator engaged in software development, including assembly language, high-level language, compilation program, editing program, debugging program, diagnostic program, process input and output program, etc.
3. Application software：Application software is the control and management program compiled by system designers for a certain production process. It usually includes, process control program, human-machine interface program, print display program and public subroutines. With the development of the hardware technology, the computer control system also puts forward higher requirements for the software. Only software and hardware cooperate with each other can give play to the advantages of computer and develop a computer control system with higher cost competitivities. At present, the industrial control software is developing towards the configuration and structured direction.
I- The environment of using industrial computers:
1. When using an industrial computer, please note that the ambient temperature should be 0~55 degrees.
2. When using an industrial computer, please pay attention to the surrounding relative humidity should be 5~90%, without condensation.
3. When using an industrial computer, the power supply voltage should be 200~240 V AC.
4. When using an industrial computer, try to avoid humidity, extreme temperature, vibration and dust drop.
5. When using an industrial computer, please try to keep a distance of more than one meter with the equipment (frequency converter, motor, etc.) that will produce strong electromagnetic interference.
II- Precautions when using industrial computers:
1. The opening on the left side of the industrial computer and the heat sink at the back of the power supply are used for ventilation. To ensure that the industrial computer work properly and reliably and to prevent overheating, do not block or cover these openings.
2. When the industrial computer is turned off, turn on again, please interval of more than 8 seconds.
3. To ensure the reliable operation of the industrial computer, it is strongly recommended not to change the BIOS Settings of the motherboard.
4. When using the I / 0 interface of the industrial computer, do not plug it plug to avoid static damage.
5. When the industrial computer encounters inhuman power failure, in order to ensure the normal and reliable work of the industrial computer, it is recommended to disconnect the power supply of the industrial computer immediately, and then power operation; if the power supply is tight and power rationing often occurs, provide the industrial computer with UPS power supply to ensure the stable operation of the industrial computers.
6. Please don’t put the industrial computers on an uneven surface.
At the end:
This article is an introduction to industrial computers, as well as the environment and precautions for the industrial computer. There is no doubt that the use of important equipment also requires maintenance, and without proper maintenance will also reduce the service life of industrial computers.
