Abstract

The invention discloses an atmospheric data computer detection system. The system comprises a control system, a signal modulation unit, a power control unit and a program control pressure source. Thecontrol system comprises an industrial control computer and various function board card inlaid into the main board of the industrial control computer as a whole control center and an operation platform; the signal modulation unit comprises a discrete signal input module, a discrete signal output module and a high-precision controllable resistor network for modulation of two types of discrete signals consisting of 'ground / overhang' and '28V / overhang' signals to achieve level conversion, control of the total temperature simulation device and output of different total temperature resistances andcontrol a digital multimeter by a relay to achieve the power source monitoring and measurement of output resistance. The problems are solved that a traditional atmospheric data computer test device istedious in operation and use steps and poor in operability and versatility.

Description

technical field [0001] The invention belongs to the technical field of air data computer testing equipment, and in particular relates to an air data computer testing system. Background technique [0002] The air data computer is an important airborne electronic device for modern aircraft. It receives the static pressure and dynamic pressure from the airspeed tube of the aircraft, and the total temperature information of the atmosphere from the total temperature sensor, so as to calculate the flight altitude and flight speed of the aircraft at that time. , flight Mach number and atmospheric parameters such as true air speed, lift speed, atmospheric static temperature, etc., and send these parameters to other airborne electronic devices in the form of digital, analog, and discrete quantities. Its performance directly affects the flight safety of the aircraft. Therefore, it is necessary to perform performance testing and fault location on the air data computer. [0003] Howev...
