【Abstract】 Some Chinese fighter planes still depend on manual management of on-board power monitoring system; this brings a number of problems, including lowering performance of the fighter. We propose to use a mini-processor system to eliminate this undesirable state of affairs.Section 1 describes in detail the design of software and hardware for our mini-processor system. Subsection 1.1 presents a "watch-dog" circuit as shown in Fig.1.Its principal functions are: (1) to track working of programming of mini-processor system; (2) to achieve on-line fault detection and fault recording;(3)to enhance the maintainability and test ability of power monitoring system. Subsection1.2 presents technical measures to ensure reliability of software of our mini-processor system.Subsection1.3 explains how to monitor all possible interrupts and to restore them to normal operation automatically. After repeatedly putting our simple mini-processor system to actual use, we are confident that it can reliably manage on-board power monitoring system for some Chinese fighter planes.更多还原
