Abstract

The invention relates to the technical field of aviation testing, in particular to an airplane windshield heating testing system and a data collecting and processing method. The airplane windshield heating test system comprises a temperature sensor, a data acquisition module, a data acquisition unit host, a computer, a display, a buzzer and a communication cable. According to the system, data of multi-channel uniform temperature acquisition is processed, a mathematical model is constructed, and the system has a working state self-checking function and a fault alarm function; high-temperature fault alarm and safety protection functions are realized; the device can communicate with a windshield heating control system, so that the preset set temperature information and the collected temperature information are integrated in the same table for information comprehensive processing, and the heating temperature and heating time of the windshield heating system are verified. Therefore, the performance test of the windshield heating system is quickly and effectively improved, the reliability and accuracy of data acquisition are realized, the information processing efficiency of the windshield heating performance test is improved through a data processing algorithm, and good safety guarantee is achieved.

Description

technical field [0001] The invention relates to the technical field of aviation testing, in particular to an aircraft windshield heating testing system and a data collection and processing method. Background technique [0002] During the flight of the aircraft, affected by factors such as weather and flight altitude, the cockpit windshield will freeze or fog, which will affect the pilot's vision. In order to prevent the windshield from freezing or fogging during the flight, A windshield heating system is installed on the aircraft. In order to ensure that the windshield reaches the predetermined temperature and effectively realize anti-icing and anti-fog, it is usually realized by designing and calculating the heating power and heating time of the windshield heating system, and when the heating system is completed, it needs to be applied on the ground The test equipment conducts performance tests on the windshield heating temperature, heating power, heating uniformity, heati...
