Industrial Personal Computer (IPC) is a ruggedized and enhanced personal computer that can be used as an industrial controller to operate reliably in an industrial environment.

Basic introduction of industrial computer

As early as the early 1980s, the American AD company introduced the MAC-150 industrial computer similar to IPC, and then the American IBM company officially launched the industrial personal computer IBM7532. Because of the reliable performance, abundant software, and low price of IPC, IPC has emerged as a new force among industrial computers, and has become more widely used.

At present, domestic brands mainly include industrial control computers such as Advantech and EVOC. It is a general term for equipment that uses a bus structure to detect and control the production process and its electromechanical equipment and process equipment. Referred to as "industrial computer". Including computer and process input and output channels. It has important computer attributes and features, such as: a computer CPU, hard disk, memory, peripherals and interfaces, and a real-time operating system, control network and protocols, computing capabilities, and friendly man-machine interface. At present, the main types of industrial computer are: IPC (PC bus industry computer), PLC (programmable control system), DCS (distributed control system), FCS (field bus system) and CNC (numerical control system).

1. IPC

It is an industrial computer based on the PC bus. According to IDC statistics in 2000, PCs currently account for more than 95% of general-purpose computers. Because of their low price, high quality, large output, and abundant software/hardware resources, they have been recognized and recognized by Fanbo’s technical staff. The foundation of industrial electricity. Its main components are industrial chassis, passive backplane, and various boards that can be inserted into it, such as CPU cards, I/O cards, etc. And adopt the design of all-steel casing, machine card layering filter, double positive pressure fan and EMC (electromagneticcompatibility) technology to solve the problems of electromagnetic interference, shock, dust, high/low temperature and other issues on the industrial site.

IPC has the following characteristics: Reliability: Industrial PC has the characteristics of dust, smoke, high/low temperature, humidity, shock, erosion, and rapid diagnosis and maintainability. Its MTTR (MeanTimetoRepair) is generally 5min and MTTF is more than 100,000 hours. The MTTF is only 10,000 to 15,000 hours. Real-time, industrial PCs carry out real-time online detection and control of the industrial production process, respond quickly to changes in working conditions, and perform timely collection and output adjustments (watchdog function is not available in ordinary PCs), self-reset in distress, Ensure the normal operation of the system. Expansibility. Industrial PC has strong input and output functions because of its baseboard + CPU card structure. It can be expanded up to 20 boards and can be connected to various peripherals, boards such as channel controllers and video surveillance on the industrial site. System, vehicle detector, etc. are connected to complete various tasks. Compatibility, can use ISA, PCI and PICMG resources at the same time, and support various operating systems, multi-language assembly, and multi-task operating systems.

2. Programmable Controller (PLC)

The full name of PLC is ProgrammableLogicController in English, and Programmable Logic Controller in Chinese. It is defined as an electronic system operated by digital operations, designed for applications in industrial environments. It uses a type of programmable memory for its internal storage of programs, executes logic operations, sequence control, timing, counting and arithmetic manipulation and other user-oriented instructions, and controls various types of machinery through digital or analog input/output Or the production process. Programmable Logic Controller (ProgrammableLogicController) is a digital operation and manipulation electronic system specially designed for applications in industrial environments. It uses a programmable memory to store instructions for performing logic operations, sequence control, timing, counting, and arithmetic operations, and control various types of mechanical equipment or production through digital or analog input and output. process. Programmable controller is a new type of universal automatic control device developed by combining computer technology and automatic control technology, which is suitable for industrial environment. It has emerged as a substitute for traditional relays. With the rapid development of microelectronics and computer technology, programmable controllers have more computer functions, not only can realize logic control, but also have data processing, communication, network and other functions. Because it can change the control process through software, and has the characteristics of small size, easy assembly and maintenance, simple programming, high reliability, and strong anti-interference ability, it has been widely used in various fields of industrial control, greatly promoting the integration of mechatronics. process.

3. Distributed control system (DCS)

It is a high-performance, high-quality, low-cost, and flexible distributed control system series product, which can form various independent control systems, distributed control systems DCS, monitoring and data acquisition systems (SCADA), and can meet various industrial fields The need for process control and information governance. The modular design of the system, reasonable hardware and software configuration and easy expansion capabilities can be widely used in distributed control of various large, medium and small power stations, transformation of power plant automation systems, and steel, petrochemical, paper, cement, etc. Industrial production process control.

4. Field bus system (FCS)

It is an all-digital serial, two-way communication system. The measurement and control equipment in the system such as probes, exciters and controllers can be interconnected, monitored and controlled. In the classification of the factory network, it is used as a local network for process control (such as PLC, LC, etc.) and application of intelligent instruments (such as inverters, valves, barcode readers, etc.), and it also has an embedded network for distributed control applications on the network Features. Because of its broad application prospects, many powerful foreign manufacturers are competing to invest in product development. At present, there are more than forty types of fieldbuses known in the world. Typical fieldbuses are: FF, Profibus, LONworks, CAN, HART, CC-LINK, etc.

5. Numerical Control System (CNC)

The modern numerical control system is a numerical control system that uses a microprocessor or a special microcomputer. The system program (software) stored in the memory in advance realizes the control logic, realizes the department or all the numerical control functions, and connects with the peripheral equipment through the interface, called the computer CNC, referred to as CNC system. The CNC machine tool is a mechatronic product formed by the penetration of new technology represented by the CNC system to the traditional machinery manufacturing industry; its technical scope covers many fields: (1) machinery manufacturing technology; (2) information processing and processing , Transmission technology; (3) Automatic control technology; (4) Servo drive technology; (5) Sensor technology; (6) Software technology, etc.
