Design Of Embedded Industry Controller Based On AT91M40800

After IT network technology, embedded system is a new direction of technique development. Embedded system has been applied in military, electronics, communication, industrial control and so on, because it has the character of small size, high performance, low cost, high reliability and oriented object program.The device of industrial automation based on the embedded chip has a deep develop space. Today many embedded controllers of 8, 16, 32-bit have been applied in the fields of industrial process control, digital control machine, electric power system, electrical net safety, electrical net device monitor, chemical system. In the field of traditional industrial control, 8-bit micro-chip controller is the main selection. But with the development of technology, 32-bit and 64-bit micro-processor gradually become the core of industrial control device.The intention of this topic is designing the embedded industrial controller which can been applied in industrial control. The main content of this article is:1. This article describes the development of embedded system, its classify, its applications in all kinds of fields and the direction of its development roundly.2. The second chapter introduces the whole design of the embedded industrial controller based on the principle of embedded system design.3. The third chapter introduces the hardware of the embedded industrial controller.4. The forth chapter introduces the embedded RTOS u C/OS which has been explanted to the hardware platform.5. In future, we will expand the RTOS to be applied to the industrial control.In a word, the article emphasizes the platform architecture of hardware and the explantoftheRTOS.
