Keywords: Industrial control computer, intelligent system, embedded system 1 Introduction Controllers provide control signals required for the coordinated operation of system components. Since the 1990s, the development of computer technology, communication technology, and control technology has driven the development of control systems towards digital, distributed, open, interoperable, and open interconnected network-oriented fieldbus control systems. New industrial control systems and products have certain control requirements and characteristics, such as real-time control, distributed control, event-driven control, and intelligent system control. These not only improve the control functions of the system but also pose new forms and higher requirements for the realization of its functions. The controllers discussed here mainly refer to control devices for mechatronic systems, such as industrial control computers, microcontrollers, and programmable logic controllers (PLCs), which are widely used in computer-aided design and manufacturing, CNC machine tools, industrial robots, and automated production lines. To enable microcomputer control systems to better adapt to the requirements of industrial applications, computer companies have specifically developed industrial control computers, or industrial PCs for short. Industrial PCs adopt standard buses and modular structures, offering many significant advantages and thus gaining increasingly widespread application. Currently, the most commonly used industrial PCs in China are STD bus industrial PCs and PC bus industrial PCs. 2. Functional Modules of Industrial PCs The functional modules of industrial PCs can be divided into three main categories: system modules, I/O interface modules, and communication modules. For STD bus industrial PCs, the system module includes the CPU module, memory module, human-machine interface, and system support module. For PC bus industrial PCs, the system module is the integrated CPU board. I/O interface modules include digital I/O modules, A/D conversion modules, D/A conversion modules, signal conditioning boards, relay output boards, etc. Communication modules include interfaces such as RS-232C, USB, GPIB, and industrial local area network interfaces. The modular structure of industrial PCs allows users to easily select configurations according to their actual needs. For example: embedded motherboard, Intel Pentium processor, DDR memory, support for 2 LAN network cards, support for LCD and VGA display, support for audio, 2 USB interfaces, etc. When selecting, consult the product catalogs of relevant computer companies. Based on system analysis, determine which templates to use to compose the application system. This is mainly reflected in the input/output interfaces and related control equipment. With system software and designed application software, the system can achieve relevant detection and control, and has graphic display and printing functions. 3 Industrial PC Application System 3.1 Detection, Data Processing System and Sequential Control System The detection and data processing system uses an industrial PC to detect various parameters in the production process, store, display, or print the detection results, and plot them into tables or curves; it can also process the detected data as needed; when the measured value exceeds the specified value or other faults occur, it can issue audible and visual alarms. The system structure diagram is shown in Figure 1. The sequential control system, under the control of the industrial PC, enables the production equipment to work systematically in a predetermined sequence. Figure 1. Structure of Industrial PC Detection and Data Processing System 3.2 Direct Digital Control System A Direct Digital Control System (DDC) utilizes an industrial PC as a digital control device to directly control the production process. The system structure diagram is shown in Figure 2. Figure 2. Structure of Industrial PC DDC System 3.3 Supervisory Control System A Supervisory Control System (SCC) calculates the optimal process setpoint based on relevant parameters and status information from the production site, according to the mathematical model and control algorithm of the controlled device, and sends it to the DDC industrial PC as the control basis. The DDC industrial PC implements PDI or feedforward control, directly directing production. Alternatively, the DDC can be omitted, and its function can be handled by the SCC. The system structure diagram is shown in Figure 3. Figure 3. Structure of Industrial PC SCC System 3.4 Distributed Control System In situations with large-scale production and complex processes, the control system can consist of multiple levels with different structural forms, also known as a distributed control system. The system structure diagram is shown in Figure 4. Figure 4. Structure of distributed control system of industrial computer 4. New technologies of industrial computer (1) Fieldbus and fieldbus control system FCS Automation technology is undergoing a major transformation, and our work is essentially centered around this transformation. Due to the development of fieldbus technology, the new generation of fieldbus control system FCS is becoming practical. This is an important hot spot of automation technology innovation, which will bring a profound revolution to automation technology. The key points of FCS are: the foundation of FCS is digital intelligent field devices; the core of FCS is the fieldbus protocol, i.e., the bus standard; the essence of FCS is the fieldization and networking of information processing. (2) PC-based industrial control computer PC-based (including embedded PC) control system, also known as IPC, is growing at a rate of more than 20%, far exceeding FCS. This is mainly due to the openness of PC. It has rich hardware resources, software resources and human resources, which benefit from the support of a large number of engineering and technical personnel and is also familiar to the general public. Major FCS manufacturers have accepted the technical route of IPC, providing rich open hardware and software platforms, which are inexpensive and easy to integrate with other information technologies. Its application scope will rapidly expand to the entire field of automation. (3) Integrated Management and Control System Integration: With the deepening of Internet technology into enterprise management and control, the integration of control and management systems has become inevitable. This makes the long-awaited goals of integrated management and control, industrial enterprise informatization, and network-based automation possible. Open distributed intelligent systems are achieved through Ethernet and Web technologies, providing modular, distributed, and reusable automation solutions based on Ethernet and TCP/IP protocol standards. The main focus is on developing network-based engineering industrial control and management software. This integrated management and control allows enterprises to choose the best solutions that truly meet the needs of the new economic era, thereby improving enterprise production efficiency and enhancing market competitiveness. (4) Industrial Ethernet: Industrial Ethernet refers not only to Ethernet with only the physical and link layers, but also to Ethernet based on Internet technology innovation, namely ETHERNET+TCP/UDP/IP+application layer. Here, UDP is better able to meet real-time requirements than TCP. Significant progress has been made in key technologies of industrial Ethernet, such as real-time performance, bus power supply, and long-distance transmission. The research objective of fieldbus control equipment based on high-speed Ethernet technology is to study key technologies of high-speed Ethernet network applied to industrial control field, including Ethernet communication real-time performance, bus power supply, intrinsic safety, interoperability, long-distance transmission, anti-interference and reliability, etc., and to study and develop field devices, networked control systems and corresponding system software based on Ethernet technology. Ethernet technology is the best solution for future control networks, and the extension of Ethernet to the enterprise field device control layer is an inevitable trend in the development of control networks. (5) New generation industrial computer bus CompactPCI The IPC industrial control computer mentioned above is based on the PC, and the active backplane of PCI-ISA bus is appropriately retained in terms of chassis and structure, and a series of industrial I/O templates are developed and expanded to form it. Since 1993, due to the advantages of PCI bus in terms of high performance, low cost and general operating system, it has been rapidly popularized and developed. However, this PCI-ISA backplane bus industrial control computer also has shortcomings and is still difficult to use in occasions with demanding requirements and high performance. To address this, manufacturers of traditional STD bus industrial PCs, such as Ziatec, ProLog, and Intel, with the support of PICMG (PCI Industrial Computer Manufacturers Association), developed a passive backplane standard and processor board standard for the PCI-ISA bus, namely CompactPCI. Their aim was to modify the PCI standard to create a passive backplane bus structure. CompactPCI is a new open industrial computer standard. Adopting CompactPCI allows for the incorporation of the latest PC technologies while offering the robustness, reliability, modularity, ease of use, and ease of maintenance necessary for communication and real-time industrial applications. Its most attractive feature is hot-swap. This means that a module can be removed or inserted from the chassis without disconnecting the power supply, and the system can automatically adjust its configuration using advanced software. CompactPCI's hot-swap is achieved through the use of three different pin lengths, ensuring that power, ground, PCI bus signals, and insertion/removal start signals are sequentially activated during module insertion or removal; it employs bus isolation devices and soft-start power supply; and it provides plug-and-play functionality in the operating system. (6) Embedded Systems Embedded systems are application-centric, computer technology-based, and customizable software and hardware systems designed to meet the functional, reliability, cost, size, and power consumption requirements of application systems. Embedded systems are highly reliable systems integrating software and hardware, with fixed application software. In addition to the CPU, the hardware includes peripheral circuitry. General-purpose and embedded CPUs, microcontrollers, and DSPs form the foundation of embedded system hardware. Embedded systems have existed for over 30 years. In recent years, the integration of computers, communications, and consumer electronics has become increasingly apparent, and embedded technology has become a research hotspot. Embedded systems have evolved into Internet-oriented embedded systems and are developing rapidly. Currently, most embedded systems are isolated from the Internet, but with the development of the Internet and its increasingly close integration with information appliances and industrial control technologies, this integration will represent the future of embedded systems. my country has recently made significant progress in embedded CPUs; the successful development of the "Loongson" and Ark CPUs is a very significant achievement. Embedded systems, due to their ever-changing requirements and lack of a unified architecture, can be uncontrollable, requiring various combinations of hardware and software. They are technology-intensive, have a large market capacity, and offer unlimited room for innovation. 5. Conclusion By integrating manufacturing technology, computer technology, and artificial intelligence, a new type of manufacturing technology and intelligent control system can be developed. This integrated system, composed of standard industrial control computer hardware and software platforms, can replace traditional closed systems. It offers advantages such as strong adaptability, good openness, easy expansion, economy, and short development cycles, and is more conducive to international information exchange, enabling the sharing of advanced manufacturing technologies worldwide.
