| ES has been used broadly in our daily life. It plays an important role as part of the control center in consumer products, telecommunication equipment and electric communication tools, such as watches, TV sets, fridges, mobile phones, PDAs, electric bikes and even other electric vehicles. Besides, a lot of large computer systems are composed of many embedded systems.However, the ES with embedded operation system has not been used in industrial equipment popularly, because the industrial equipments have strict request on stability and reliability, broad range of operation temperature, performance of anti-EMI (EMI : Electro Magnetic Interference), low rate of system malfunction, and long time continuous operation.This paper introduces ES and embedded operation systems, especially embedded Linux operation system based on the current ES application in China. The paper analyzes the feasibility of applying embedded ARM and Linux on industrial equipment and provides the solutions for applying ARM7+μClinux on industrial equipments. Based on the our company's R&D project "Industrial Network Equipment Development", it also illustrates how to design and develop the product with ARM7+μClinux as the core, which includes diagram design of general hard and soft wares, and technical function specification and implement methods of all hard and software modules.This paper finally provides the main technical index and inspection and test results. Based on the test results and running for a period, it is proved that the industrial network equipment we developed reaches the industrial standards in terms of technical function, stability, reliability, and real-time. Meanwhile, because embedded Linux operation system is successfully used in the industrial network equipment, it not only improves the function and intelligence of the equipment greatly but also reduces the development period which makes the equipment more competitive in term of performance and cost... |
