Helicopter dual-channel engine parameter acquisition and display system

Abstract

The invention discloses a helicopter dual-channel engine parameter acquisition and display system, which comprises a channel I and a channel II with the same structure, and is characterized in that the channel I is connected with the channel II, the channel I and the channel II are mutually used as backups, each of the channel I and the channel II comprises a signal conditioning module, a data acquisition and processing module, a power supply module and a display module, the power supply module supplies power to the signal conditioning module, the data acquisition and processing module and thedisplay module, the signal conditioning module is connected with the data acquisition and processing module, and the data acquisition and processing module is connected with the display module; the signal conditioning module of the channel I is cross-linked with the data acquisition and processing module of the channel II, and the signal conditioning module of the channel II is cross-linked withthe data acquisition and processing module of the channel I; and the data acquisition and processing units of the channel I and the channel II are cross-linked with each other.

Description

technical field [0001] The invention belongs to the technology related to the collection, processing and display of helicopter electromechanical parameters, and in particular relates to a helicopter dual-channel engine parameter collection and display system. Background technique [0002] The main function of the engine parameter collection and display system is to realize the collection and display of engine and related system parameters. The traditional engine parameter acquisition and display system is a single-channel system. When the system fails during use, the pilot completely loses the indication of the engine parameters, which affects flight safety. [0003] Among the currently retrieved patents, US20030193411A1 and WO0065423A2 claim protection of an engine parameter display for an electronic flight instrument system, the electronic flight instrument system includes at least one circular indicating instrument, and the instrument has at least one In the coloring are...

Problems solved by technology

The traditional engine parameter acquisition and display system is a single-channel system. When the system fails during use, the pilot completely loses the indication of the engine parameters, which affects flight safety.

[0003] Among the currently retrieved patents, US20030193411A1 and WO0065423A2 claim protection of an engine parameter display for an electronic flight instrument system, the electronic flight instrument system includes at least one circular indicating instrument, and the instrument has at least one The coloring area, the size and color of the coloring area change with parameter fluctuations, and there is only a single channel, and the engine parameter indicators cannot be observed when the system fails

[0004] And Chinese patent CN105416601A claims a kind of helicopter engine parameter display system, is used for providing optimized parameter display to the driver, mainly is that the displayed parameter comprises the parameter display of ESI parameter, Ng, ITT, TQ and the calculating method of ESI, It also cannot solve the problem of observing engine parameter indicators when the system fails
