Ground detection device used for electronic controller of engine

Abstract

The invention discloses a ground detection device used for an electronic controller of an engine. The ground detection device used for the electronic controller of the engine comprises a serial communication circuit, a self-inspection unit, a communication detection unit and a power source detection unit, wherein the serial communication circuit is used for establishing communication connection with the electronic controller; the self-inspection unit is connected with the serial communication circuit and used for judging whether the electronic controller is self-inspected normally or not; the communication detection unit is connected with the serial communication circuit and used for detecting whether the communication function of the electronic controller is normal or not; the power source detection unit is used for judging whether a primary power source and a secondary power source of the electronic controller are normal or not; the primary power source is an external input power source received by the electronic controller; the secondary power source is a power source which is needed by internal working and generated after the electronic controller converts the primary power source. The ground detection device extends the detection items for the electronic controller, the types of faults of the electronic controller are conveniently, rapidly and accurately located, the electronic controller is overhauled as soon as possible, the faults are detected without special knowledge, operation is easy and convenient, and the ground detection device is convenient to use.

Description

technical field [0001] The invention relates to the field of aircraft engine control, in particular to a ground detection device for an electronic engine controller. Background technique [0002] The electronic controller of the aeroengine is the brain of the engine. It collects signals such as engine temperature (intake temperature Tt1 and exhaust temperature Tt7, respectively, platinum resistance and thermocouple signals), speed (n, frequency signal) and other signals, and uses communication to receive The instructions from the flight control computer, and then through the control algorithm, control the action of the corresponding actuator (switch output), so as to realize the state change of the engine. [0003] At present, after the electronic controller is delivered to use, the aircraft integrated control computer can only be used to check whether the communication and self-check results of the electronic controller are normal (on the one hand, the aircraft integrated c...
