Information acquisition system and method

Abstract

The invention, which relates to the technical field of simulation, discloses an information acquisition system and method. The system comprises a lower computer, an upper computer and an interface module, wherein the upper computer and the interface module are in communication connection with the lower computer. During application, a control surface information acquisition model comprising at least one sub-model for acquiring control surface information data by the lower computer is established by the upper computer. And the upper computer is also used for respectively inputting configurationinformation containing the operating system information of the lower computer into each sub-model. Meanwhile, the upper computer can compile the sub-models into execution files capable of being executed by the lower computer and send the execution files to the lower computer, and the lower computer collects control surface information data of the aircraft through the interface module according tothe sub-models in the execution files and feeds back the collected data to the upper computer. Compared with the prior art, the disclosed information acquisition system not only can realize acquisition of control surface information data but also can be used as a real-time simulation platform of an airplane; and the acquired control surface information data can be directly used for real-time simulation of a closed loop of the airplane.

Description

technical field [0001] The embodiments of the present invention relate to the field of simulation technology, and in particular to an information collection system and method. Background technique [0002] The rudder surface refers to the aerodynamic wing surface that uses the balance force and control force of the aircraft generated by deflection in the airflow to control the flight of the aircraft, also known as the control surface. The aircraft uses a high-precision, high-reliability rotary variable differential transformer (Rotary Variable Differential Transformer, RVDT) sensor to measure the deflection of the aircraft rudder surface. RVDT is an angular displacement sensor. Transmit the rotation of the mechanical parts to the shaft of the angular displacement sensor, drive the spoiler connected to it, change the induced voltage in the coil, and output a voltage signal proportional to the rotation angle. [0003] The rudder surface information acquisition system is used ...

Problems solved by technology

[0005] At present, the existing information collection system is usually based on the Windows operating system or realized by an embedded microcontroller. It is a non-real-time operating system, and the existing information collection system is usually a dedicated collection system developed for a certain type of software. The system and software are not universal, and the staff cannot modify them, or it is difficult to modify them

Moreover, the existing information collection system is not compatible with the aircraft real-time simulation platform, and the collected rudder surface information data cannot be directly applied to the aircraft real-time simulation application based on the upper and lower computer architecture
