Overview
Industrial Personal Computer (IPC) that is, industrial control computer, is a bus structure, the production process and electromechanical equipment, process equipment for detection and control of the tool in general. IPC has important computer attributes and characteristics, such as having a computer motherboard, CPU, hard disk, memory, peripherals and interfaces, and operating system, control networks and protocols, computing power, friendly human-machine interface. Industrial control industry products and technologies are very special, belonging to the intermediate products, is to provide stable, reliable, embedded, intelligent industrial computers for various other industries.
The main categories of industrial controllers are: IPC (PC bus industrial computer), PLC (programmable control system), DCS (decentralized control system), FCS (fieldbus system) and CNC (numerical control system).
Internal Structure
Hard disk drive rack, optical drive rack: hard disk drive rack is generally divided into two kinds, one is split type, a kind of pressure card type. Excellent quality chassis are generally with metal springs anti-vibration function; the number of installed hard disk generally from 4-15;
Base plate: there are various specifications of the base plate; mainly divided by the specifications of the motherboard. Ordinary motherboards can generally be installed; which 520MM length of the following chassis can not be installed 12 * 13 of the dual-extreme motherboard, must be 520MM length of the chassis can be installed.
Pressure card strip: mainly play a fixed role. There are security monitoring installation video long card, or industrial CPU long card, must be fixed long card, so as to avoid the use of the process of shaking, not solid and other phenomena.
Expansion of the back slot: 7-slot or 14-slot two; 14-slot backplane is the main purpose of the installation of multi-channel video card, such as some large-scale monitoring system, then 64-way, or 128-way, must be replaced with 14-slot backplane;
Advantages and disadvantages
Industrial computer is commonly known as a computer designed specifically for industrial sites, and industrial sites generally have a strong vibration, dust is particularly high, another high electromagnetic field force interference and other characteristics, and general factories are continuous operation that is generally no rest in a year. Therefore, the industrial control machine must have the following characteristics compared with ordinary computers:
1, the chassis adopts steel structure, has a high anti-magnetic, dustproof, anti-impact ability.
2, the chassis has a special base plate, the base plate has PCI and ISA slots.
3, the chassis has a special power supply, power supply has a strong anti-interference ability.
4,Requirements for continuous long-time working ability.
5, generally easy to install the standard chassis (4U standard chassis is more common)
Note: In addition to the above characteristics, the rest is basically the same. In addition, as a result of the above professional characteristics, the same level of industrial control machine in the price than ordinary computers on the expensive side, but generally does not differ too much.
Although the industrial control machine and ordinary commercial computer machine, compared with the unique advantages, but its disadvantages are also very obvious - poor data processing capabilities, as follows:
1, the configuration of the hard disk capacity is small;
2, low data security;
3, storage selectivity is small;
4, higher prices.
And the difference between ordinary computers
Industrial computer: mainly in the stability, so the heat dissipation of the industrial computer is very good, there are special air ducts, and 4-6 cooling fans. Even if one of the fan failure, a short period of time will not have an impact on the temperature. Industrial production continuity is very strong, the computer may require year-round boot without dying. So, only a reliable temperature is guaranteed for it to run properly.
Home computer: important in the speed, the very external devices. General home computer, wireless reception, bluetooth module, 7.1 audio, external projector is now also very common, it is the direction of development is, feature-rich, fast running speed.
Industrial control machine: the power requirements of stability and reliability, industrial control machine power supply power is not large, but the power supply in the circuit board of each resistor capacitors are industrial-grade, and even military-grade. It is required in the years and years without resistance and capacitance changes.
Home computer: power supply is now generally larger power, 500W power supply is now very common, it is to give the computer in the large graphics card power supply. However, power supply manufacturers in order to reduce costs, so, although the power is large, stability needs to be further improved. After all, every time an electronic component is raised to a higher level, the price is likely to increase exponentially.
And the difference between the host computer
Industrial control machine is an industrial control computer
The host computer is in the upper level of control, non-direct operation of the machine mechanism action of the equipment
The upper computer is not equal to the industrial control machine, only the industrial control machine is often used as the upper computer to use
200 meters can use 485 communication, fiber optic is also possible, but I have not used, in addition, you can also communicate through the network interface
And the difference between the touch screen
Industrial Personal Computer (IPC), which can be used as an industrial controller to operate reliably in industrial environments. The touch screen can be used as the input and display unit of the IPC, and the touch screen of the IPC is also made into an all-in-one, which is a touch screen but has the function of the IPC.
HMI is an abbreviation for Human Machine Interface, also known as touch screen, "human-machine interface", also known as human-machine interface. Human Machine Interface (also known as user interface or user interface) is the medium of interaction and information exchange between the system and the user, which realizes the internal form of information and human acceptable form of conversion between. Human-computer interfaces exist wherever human-computer information is exchanged.
