Embodiment Construction

[0020] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0021] The steps of the detection method of this kind of aircraft digital fuel measurement control system are:

[0022] (1) Input the simulation signals of the fuel quantity of all fuel tanks, the simulation signals of instantaneous fuel consumption of four engines and the simulation signals of fuel temperature compensation of each fuel tank of the aircraft to the fuel measurement control system in the aircraft;

[0023] (2) During the detection process, input the simulated control signals of the aircraft's fuel supply pump, fuel delivery pump, injection pump, and refueling valve to the fuel measurement and control system in the aircraft;

[0024] (3) Collect the 32-bit ARINC429 aviation data bus data sent by the fuel measurement computer of the fuel measurement control system in the aircraft through the 429 bus communication...

Abstract

The invention relates to a detection method of plane digit fuel measurement control system and a relative device, which comprises (1) inputting the fuel level simulation signal of all oil tanks, instant consumption simulation signal of four engines and the fuel temperature compensation simulation signal of each fuel box into the fuel measurement control system of plane, (2), inputting the simulation control signals of plane feed pump, transmission pump, injection pump and accelerator into the fuel measurement control system of plane in the detection, (3), using a 429 bus communication board to pick up the data of 32-bit ARINC420 aviation data bus sent from the fuel measurement computer of the fuel measurement control system, calculating and displaying the data on a panel. The invention can avoid large plane wing model in the test of fuel measurement control system, while the simulator can be independently used in plane external field, with high test accuracy, consist experiment conditions, high test speed, reduced operator number and improved working efficiency.

Description

technical field [0001] The invention relates to a detection method and a device for an aircraft digital fuel measurement control system, belonging to ground support equipment for quantitatively inspecting performance technical indicators of the aircraft digital fuel measurement control system before installation. Background technique [0002] At present, the test of the performance technical index of the aircraft digital fuel measurement control system is completed by establishing a special fuel system laboratory. It is required to establish a model with a ratio of 1:1, including at least the left or right wing of the aircraft. During the test, the aircraft to be tested must be filled with fuel, and the refueling volume should reach more than 20 tons. The working environment of the measurement control system is the same as that of the aircraft, thus realizing the full simulation test of the aircraft digital fuel measurement control system. In addition, the fuel system labor...
