The Embedded System

The demand for equipment has been unable to meet the current and future high performance application anddevelopment needs with the rapid development of electronic technology and upgrading of traditional industries inChina. At the same time, intense market competition and technical competition require that the development cycle ofthe product to be as short as possible. Obviously, the software and hardware of embedded system are becoming moreimportant foundation of technological innovation in various fi elds. The embedded system is a combination of advancedcomputer technology, semiconductor technology, electronic technology and the specific application of variousindustries. This determines that it must be a technology-intensive, capital-intensive, highly fragmented and innovativeknowledge integration system. The embedded type is based on the application of computer technology-based hardwareand software can be tailored to adapt to the application system on the function, reliability, cost, size, power and otherstrict requirements of the special computer system. The emergence of consumer appliances and cheap microprocessorsembedded systems will form larger application areas in daily life to as the embedded system usually has low powerconsumption, small size and high integration. Embedded employment is widely embedded in the social needs of largetalent. The content of the paper is clear in the embedded control system overview - development - application writingideas in three chapters gradually. Chapter 1 introduces the defi nition, frame, characteristic, development history, currentsituation and prospect of the embedded control system in detail.

Embedded system becomes one of widely-employed system schemes applied in broad areas, such as power conversion, industrial control, test and measurement, and so on. A universal test scheme with full-coverage on inner variables is present, which will improve the testability of power conversion embedded control system. Feathers of this embedded control system are introduced, and the function structure of the general test scheme is described. Some key problems of the test scheme, such as data type, variable property table, multi-type pointer array, and multi-type data packing and unpacking are discussed. Finally, the effect of the universal test scheme is testified by the implementation of a typical power conversion demonstration.

Increasing demands on the productivity of complex systems, such as machine tools and their steadily growing technological importance will require the application of new methods in the product development process. This paper shows that the analysis of the simulation results from the simulation based mechatronic model of a complex system followed by a procedure that allows a better understanding of the dynamic behavior and interactions of the components. Mechatronics is a design philosophy, which is an integrating approach to engineering design. Through a mechanism of simulating interdisciplinary ideas and techniques, mechatronics provides ideal conditions to raise the synergy, thereby providing a catalytic effect for the new solutions to technically complex situations. This paper shows how the mechatronic products can exhibit performance characteristics that were previously difficult to achieve without the synergistic combination. The paper further examines an approach used in modeling, simulation and optimization of dynamic machine tools and adopts it for general optimized design of mechatronics instrumentation and portable products. By considering the machine tool as a complete mechatronic system, which can be broken down into subsystems, forms the fundamental basis for the procedure. Starting from this point of view it is necessary to establish appropriate simulation models, which are capable of representing the relevant properties of the subsystems and the dynamic interactions between the machine components. Many real-world systems can be modeled by the mass-spring-damper system and hence considering one such system, namely Mechatronics Technology Demonstrator (MTD) is discussed here. MTD is a portable low cost, technology demonstrator, developed and refined by the authors. It is suitable for studying the key elements of mechatronic systems including; mechanical system dynamics, sensors, actuators, computer interfacing, and application development. An important characteristic of mechatronic devices and systems is their built-in intelligence that results through a combination of precision, mechanical and electrical engineering, and real time programming integrated to the design process. The synergy can be generated by the right combination of parameters, that is, the final product can be better than just the sum of its parts. The paper highlights design optimization of several mechatronic products using the procedures derived by the use of mass spring damper based mechatronic system. The paper shows step by step development of a mechatronic product and the use of embedded software for portability of hand held equipment. A LabVIEW based platform was used as a control tool to control the MTD, perform data acquisition, post-processing, and optimization. In addition to the use of LabVIEW software, the use of embedded control system has been proposed for real-time control and optimization of the mass-spring-damper system. Integrating embedded control system with the mass-spring-damper system makes the MTD a multi-concepts Mechatronics platform. This allows interface with external sensors and actuators with closed-loop control and real-time monitoring of the physical system. This teaches students the skill set required for embedded control: design control algorithms (model-based embedded control software development, signal processing, communications), Computer Software (real-time computation, multitasking, interrupts), Computer hardware (interfacing, peripherals, memory constraints), and System Performance Optimization. This approach of deriving a mathematical model of system to be controlled, developing simulation model of the system, and using embedded control for rapid prototyping and optimization, will practically speed product development and improve productivity of complex systems.

In order to meet the factory detection requirements of the rotary electronic dobby, a new design of the detecting platformfor the rotary electronic dobby was proposed in the present study. It was composed with three main modules to meetthe different levels of detecting process all over the factory, including the embedded control system, human machineinterface system and the information management system. For the information management system of the dobbyworkshop, the proposed platform performed the remote management, results monitor, and data analysis to the dobbymanufactured at the factory. For the operators of the dobby detecting process, the human machine interface systemrealized the edit of pattern, the upload and download of the pattern data based through Wi-Fi, the control of motor speed,the test process record and the upload of the test results. Moreover, the embedded control system was developed andbuilt to realize the real-time control to electromagnet and swing arms of dobby according to the pattern stored in flashchip and status display of the detecting results on the platform. The designed detecting platform in this article can bewidely applied in the factory for detection of the rotary electronic dobby. The reliability and practicability of the proposedplatform have been confirmed by the practical application of the dobby manufacturing enterprise.
