The Microprocessor-based Monitoring Apparatus Of Unattended Double-diesel Generating Set

Diesel generating set had become the preferred backup or emergency power because of these characteristics: tight structure, small size, thermal efficiency, rapid start, flexible control.Compared with the same capacity of single units, the double-diesel generating set work well, make less investment, have high usage rate, and economize on energy-saving obviously when the carry is big variety.The project discussed the characteristics and development condition of microcomputer monitoring apparatus on diesel generators particularly double units, analyzed the principle of microcomputer monitoring apparatus regulation and realization method, and put forward the design idea of miniature double-diesel generators monitoring apparatus based on AT89S52. On the base of which, this topic developed the hardware system and software module.The system adopted AT89S52 microcontroller as the main part of automatic monitoring apparatus. The development environment was very mature, It could complete the following functions: testing city power, the units start, testing the capacity of the units, automatic quasi-synchronization parallel and Sequence control etc.The exploit of microcontroller adopted assemble language. Assemble language was a kind of structured programming language, it had many characteristics of other high-level languages. Software exploitation adopted building block design. It's commonality was good and easy to improve and expand. So we could develop larger-scale system with more perfect performance. Besides, anti-jamming technology is necessary.The system had many advantages. For example, its volume was small, reliability was high, special use was strong, and its price proportion was ideal, etc. It was proved by testing that, it could satisfy the control command of medium and small sized generator.
