Design And Implementation Of Controller Of Diesel Generator Set Based On μC/OS-Ⅱ

In today's society, diesel generator set is the important main power or spare power in production and life, while supervisory control system of diesel generator set is an important component. With the development of electronic technology and computer control technology, more and more digital and intelligent supervisory control systems of diesel generator set are available, and have strong market competitiveness compared with the traditional ones using instruments of pointer type. Besides, homebred supervisory control systems are more and more close to foreign products on technology level. Under the background, this paper designed a controller of diesel generator set based on 32-bit microcontroller ARM7, referring to home and abroad advanced technology and control function. And it firstly attempt to apply the Multitasking real-time operating system ofμC/OS-Ⅱ.It is elaborated from two sides of hardware and software. In the hardware, it uses LPC2214 chip of Philips Company as the main chip of control, applies ATT7022A, an energy measurement chip of Zhuhai Actions Company at home, to sample power parameters. Parts of the remaining parameters are converted by TLC2543 A/D converter of TI Company after sampled. Sampled parameters are real-timely displayed by LCD screen. In the software, operating system ofμC/OS-Ⅱis applied. The paper analyzes the transplantation ofμC/OS-Ⅱunder the ADS1.2 IDE, partitions different tasks according to the system's oriented functions and introduces each task's function. Besides, the Modbus Protocol which is used in the system, with the its realization in the terminal, is introduced. Finally, The paper summarizes the situation about the software debug and function test.It makes software design with embedded real-time operating system in the controller of diesel generator set for the first time, which gets expected result and realizes the"Three Remote"function.
