REALIZATION OF A VOTER/MONITOR FOR A DIGITAL FLIGHT CONTROL SYSTEM

A software Voter/Monitor (V/M) system is designed and implemented. The V/M is an informational processing device which is to be used in a digital flight control system (DFCS). A DFCS is currently being developed to replace existing analogue flight control systems in selective military aircrafts. The V/M receives data over four separate input channels, and it performs a processing routine which (a) allows it to continually select one of the input channel data for routing over its single output channel; and (b) allows it to maintain a history of each input channel data for routing over its single output channel; and (b) allows it to maintain a history of each input channel performance and declare as defective any input channel from which it consistently receives 'bad' data. The V/M is implemented using the National Semiconductor IMP-16L Microcomputer. The V/M processing scheme uses input-input comparison monitoring. Software coding and hardware circuitry are designed. Additionally, a software test program is constructed. The V/M system testing is limited. The correct performance of the V/M system is illustrated under a static testing environment.
