Case presentation

Application of cable displacement sensor in anti rollover early warning of aerial vehicle

Release date: June 25, 2019 Hits: 170

Aerial work vehicle is widely used in electric power, wind power, street lamp, municipal, garden, communication, airport, shipbuilding, transportation, advertising, photography and other fields of aerial work. It has the advantages of wide application range, flexible mobility, rapid and convenient transfer. It has high adaptability and broad application and development prospects. Due to the large nonlinear deformation of the boom of the aerial work vehicle, excessive inertial force caused by misoperation, sudden subsidence of the support surface or excessive wind force, the phenomenon of sudden loss of stability and sometimes even overturning occurs when the aerial work vehicle is working. According to incomplete statistics, the safety accidents caused by the rollover of aerial vehicles account for 60% - 70% of the total accidents of the vehicle. Therefore, it is of great practical significance to study the anti rollover early warning system for aerial vehicles.

The displacement sensor and the angle sensor are respectively connected with the single-chip microcomputer, and the output end of the single-chip microcomputer is connected with the alarm. Eps-s-2000mm-a type displacement sensor is selected Rope displacement sensor The sensor converts the mechanical displacement into voltage output through the potentiometer element, and the movable brush is connected with the main arm of the aerial vehicle. The displacement of the object causes the resistance change of the moving end of the potentiometer. The change of resistance value reflects the displacement value, and the increase and decrease of resistance value indicate the direction of displacement. This kind of sensor has the technical characteristics of long service life, strong environmental adaptability and strong anti-interference ability; Wdd35d4 inductive angular displacement sensor is selected. The sensor has the characteristics of simple and reliable structure, high output power, good anti-interference, low environmental requirements, high resolution, small indication error, good stability and low price.
