Abstract

The invention discloses a heating control device for an aircraft air data system. The heating control device includes: a power module capable of providing a test power supply, a half-power heating power supply and a full-power heating power supply; a heating control circuit for Selectively connect one of the power sources of the power module and the self-test circuit or working circuit of the heating control device; the control module is used to receive the test start signal, the engine start signal and the open space status signal, and control the heating control circuit accordingly Selectively connected to one of the power supplies of the power supply module and selectively connected to the self-test circuit or the working circuit; the fault monitoring module is used to judge whether there is a failed component and output Warning message. The present invention can utilize signals such as engine state signals, aircraft air-ground state signals, etc. to realize automatic switching and execution of completeness inspection and heating of load equipment according to different operating states of the aircraft.

Description

technical field [0001] The invention relates to an air data system of an aircraft and a heating device for heating it, in particular to a heating control device for an air data system of an aircraft. Background technique [0002] The air data system is an important airborne electronic device, and its performance and accuracy are directly related to the flight safety of the aircraft. In order to ensure the safe flight of the aircraft under icing weather conditions, the air data probe usually has a heating and deicing function, which is controlled by the air data heating controller (Air Data Heater Controller). The air data heating controller belongs to the equipment of the aircraft air data system. It is mainly used to control the heating status of pitot tubes, static pressure holes, total temperature sensors, angle of attack sensors and other equipment, and to monitor their integrity in real time. [0003] The heating controllers used on existing aircraft mainly include the...
