Abstract

The invention discloses a device for vibration monitoring data of a turboshaft engine. By means of the device, the problems that factors of hovering, low-altitude flying and the like of existing helicopters are very likely to cause damage, abrasion and corrosion of an engine, besides, factors of installation, use, maintenance and the like of the engine have an influence are solved. The device comprises a main control chip ARM, a high-speed Ethernet chip W5300 connected with the main control chip ARM, a RJ-45 port connected with the high-speed Ethernet chip W5300, a data collection chip FPGA connected with the main control chip ARM, a simultaneous dynamic random access memory (SDRAM) connected with the data collection chip FPGA, an A / D collector connected with the data collection chip FPGA and a signal conditioner connected with the A / D collector. By means of the scheme, the purpose of improvement of the durability and reliability of the engine is achieved, and the device has very high practical value and popularization value.

Description

technical field [0001] The invention relates to the field of engines, in particular to a device for vibration monitoring data of turboshaft engines. Background technique [0002] The engine is the power source of the aircraft, and its working status directly affects the safety and reliability of the aircraft. The failure environment of the turboshaft engine on the helicopter is harsh, not only need to withstand high temperature and greater stress, but also need to withstand a large alternating load. At the same time, helicopters usually take off and land in harsh environments. Factors such as helicopter hovering and low-altitude flight can easily cause damage, wear and corrosion of the engine. In addition, due to the influence of engine installation, use, maintenance and other factors, vibration has become a major problem for turboshaft engines. One of the main glitches. In order to reduce the vibration of the engine and improve the durability and reliability of the engine...
