"Embedded System" generally refers to a non-PC system, a computer function but not called a computer or equipment for a computer. It is a dedicated computer system that is used as centered, hardware and software, adaptable to application system on functional, reliability, cost, volume, and power consumption, etc., mainly complicated with comprehensive strict requirements; mainly by embedded processors, related support hardware, Embedded operating systems and application software systems. Compared with the general-purpose computer system, the embedded system is low, high reliability, powerful, high performance ratio; real-time, support multitasking; small space, high efficiency; facilities, can be flexible as needed custom made. Embedded systems are widely available: can be used in mobile computing platforms (PDA, handheld computer), information appliance (digital TV, set-top box, network equipment), wireless communication equipment (smartphone, stock receiving equipment), industrial / commercial control (intelligent industrial control equipment) , POS / ATM machines, e-commerce platforms, and even military applications. It is estimated that its related industrial output in the world has exceeded 10 trillion US dollars. As a combination of embedded techniques and automated configuration software technology, "embedded automated configuration software" refers to embedded applications for embedded systems and network features (including Internet service functions). It greatly shortens the time of embedded products to put the market, and makes the product have a wealth of man-machine interface, embedded web, and control logic functions in accordance with IEC61131-3 standards, and store considerable number of historical data, and partially completed on-site workstation level Computer features. Foreword entered the 21st century, the digital products are thriving; because the hardware platform is different, the embedded software market presents a highly subdivided pattern, and it is difficult to monopolize the entire market after entering foreign products. This provides a software industry for my country. A rare development opportunity. As a well-known company in the domestic automation software industry, Beijing Kunlun Tong-State Automation Software Technology Co., Ltd. took the lead in launching embedded automation configuration software in China on June 24 - MCGS embedded mode software, and proposed "DIY freedom of industrial control equipment The new idea of configuring, using users from cumbersome programming, can construct their own application through simple modular configuration. At the same time, they connect their hands with Microsoft and Advanhua Technology, from June 24th to July 25th, in Chengdu, Xi'an, Beijing, Shenyang, Shanghai, Guangzhou, Dongguan, Harbin and Nanjing and other 9 cities. " The technical and application of embedded system configuration software and platform "seminar," embedded "cyclone is set off in the industry. This journal editorial department introduces you to the Seminar Shanghai Station. The theme speech Shanghai station is held on the afternoon of the World Trade Mall on July 8th, with approximately 150 representatives from Shencheng and surroundings. In addition to listening to a wonderful topic, they can also communicate in depth through the application prospects of the embedded system through a vivid image demonstration system. Like other cities, the theme of this seminar is introduced by Advantech, Microsoft, and Kunlun Tong-state, the concept of Advantech embedded equipment, Microsoft Windows CE, and Kunlun Tong-state MCGS embedded version configuration software. , Product and application cases. Mr. Hejie (Executive, Embedded Computer Division, East China Sales Manager) Report Topics: Embedded Systems In the New Era Development Trend and Technical Sanmetal, the computer has entered the PC era. The 3 tasks facing IT operators are: handling people who cannot handle people with PC technology; enabling each traditional equipment to connect to a computer; digital products are widely popular. With the continuous improvement of information automation requirements, many non-PC devices have a broader future. Form-wide digital equipment is trying to penetrate the Internet into every corner of life. Combine PC with traditional equipment to make the latter have operations and networked capabilities, which is an inevitable trend of embedded applications and is the development of PC technology. Industrial site and remote equipment also need intelligent development and transformation, so embedded systems are very broad in the application prospects of the industrial control industry.
The embedded system mainly has four development trends: (1) open platform architecture, easy to integrate with other systems; (2) The volume is getting smaller and smaller, the performance requirements are more stable, the cost is lower; (3) the application tends to diversify, A small batch, fast and customized service; (4) The function tends to be single, the integrated function is different from the general PC. Advantex's embedded system, the embedded computer business department, mainly for small and medium system integrators, including embedded motherboards (SOM system modules, DTOS services, single-board computers and accessories, POS control board, PC / 104 module, etc.), embedded chassis, liquid crystal tablet (liquid crystal ultrasound integrated computer, open touch terminal equipment, etc.), and embedded software. During the development of new products, some basic needs are implemented using standard module products. Based on this concept, Advantech has launched SOM (System ON Module) solutions, so that customers can focus on their own needs. The function module is developed, produced without considering the complex CPU module; at the same time, Advana can also provide SOM expansion board design services and samples according to customer needs, helping customers in 30 days ODM their own industrial control motherboard. Mr. Liu Zhijun (General Manager of Kunlun Tangle) Report Topics: MCGS Embedded Configuration Software and its solution mainly introduces the latest Windows CE-based MCGS embedded configuration software, as well as "DIY free configuration of industrial control equipment" new idea. Software platform based on embeddedded OS; all functions with MCGS universal version; users can use to quickly develop embedded application systems; only less hardware resources, reduce system costs; stable and reliable, long long Time operation is not dead; fast running speed, fast acquisition and real-time control. These six aspects are more comprehensive and concretely summarized in the concept of MCGS embedded configuration software. This configuration software graphics interface, device driver, control flow, and data processing can be configured, and network connections can also be conveniently. Unlike previous PC-based industrial configuration software, MCGS embedded mode software has the following features: powerful, and the MCGS general version is basically the same; easy to use, the configuration method is also consistent with the general version; it is really embedded Configuration software, using Windows CE embedded operating system; cost-effective, only 32MB, 486DX CPU; reliability, use watchdog, automatic start; real-time, easy to achieve fast acquisition and high speed control. So far, Kunlun Tong is introduced 3 major series of MCGS configuration software: universal version, network version and embedded configuration software, forming a three-piece persistent integrated solution, can accomplish data from industrial field equipment, workstation data processing And control, all functions to host network management and web browsing. (1) MCGS network version configuration software, at the top of the entire system, mainly complete the information collection and release of the system, and collect all monitoring information to the server through the network. (2) MCGS universal version configuration software, in the middle of the system, complete the data processing processing of the workstation, and some daily monitoring transactions. (3) MCGS embedded version of the configuration software, in the uppermost layer, collect, process and control on site data. It can be combined with hard devices to develop equipment required to make a variety of users, such as smart meters, paperless recorders, unattended live collection stations, etc. At the same time, Kunlun Tongmata created a new idea of "Industrial Control Equipment DIY Free Configuration". Users do not need to make cumbersome programming, simply selecting and simple configuration of modules, can construct an application system that is suitable for their own.
In response to DIY, Liu has proposed six issues that need to be solved when implementing: (1) Structure Problem: There is a unified housing similar to PLC, can connect multiple PC104 boards; (2) Wiring issues: Because PC104 is tape The cable is connected, and thus the device is set, convert the cable connection into a terminal; (3) Software problem: Improve the stability of the system, increase ladder and FBD programming; (4) Hardware issues: PC104, manufacturers, High price, easy to solve; (5) bus issues: Support PROFIBUS, LONWORKS, Interbus; (6) Open issue: Standard by PC104, allowing users as many users to produce, developing various functions. Finally, Liu has brought a large number of successful cases to analyze the application of MCGS embedded mode software in practical projects, and look forward to DIY's beautiful prospects in various fields in industrial control. Due to time and other factors, the organizer failed to arrange the introduction of the embedded operating system Windows CE, which is not allowed to make some regrets. In order to ensure the integrity of the entire report, this publication collects relevant information and simply makes an introduction. Windows CE is a multi-threaded, complete priority, multitasking operating system designed for a limited resource platform. Its modular design allows it to be customized for user electronic devices from the handheld to a dedicated industrial controller. The basic kernel of the operating system requires at least 200 kB of ROM. With the opening of the Windows CE source, and Microsoft is strengthened in the embedded field, its custom capacity has risen; coupled with the useful resources, and thus prospects are optimistic about people. Windows CE.NET is the successive product of Windows CE 3.0, with a complete operating system feature set and end-to-end development environment, including the functions required to create a Windows CE-based custom device, such as networking capabilities, real-time and small Memory volume occupation, and rich multimedia and web browsing feature. Due to the use of the MSMQ (Microsoft Message Queuing application service, Windows CE makes it possible to achieve comprehensive integration with industry-production site existing IT facilities. Because Windows CEs can start from flash disks, it also avoids exposure to dust, high temperature and vibration environments, so that it can be applied to harsh production environments. The gap between the Seminar, the editorial department of this journal conducted a live interview with the representative of the organizer and the participating representative.
