Embodiment Construction

[0025] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] figure 2 Shown is the structural principle diagram of the solid pendulum type inclination sensor. Such as figure 2 As shown, taking the measurement of the inclination angle of the solid pendulum inclination sensor as an example, the solid pendulum inclination sensor is composed of a bracket 5, a cycloid 6 and a pendulum 7, and it is actually an acceleration sensor based on the principle of inertia. The bracket 5 is fixed on the working platform, one end of the cycloid 6 is fixed on the bracket 5, and the other end is a free end, which is connected to the pendulum 7, and the pendulum 7 will produce an inclination angle with the vertical surface along with the inclination of the working platform, namely The angle α between the pendulum 7 and the vertical direction. The solid pendulum inclination sensor actual...

Abstract

The invention relates to a working platform inclination angle measurement method and an apparatus thereof. The method comprises the following steps: acquiring the inclination angle beta between a working platform and a vertical plane in the rotation state through an inclination angle sensor arranged on the workbench, and acquiring the rotation angle rate omega of the working platform in the rotation state through an angular rate sensor arranged on the working platform; measuring the rotation radius R of the working platform through a radium measurement instrument; and calculating through utilizing a formula alpha=arcos(x-y) to obtain the practical inclination angle alpha of the working platform, wherein x=cosbeta, y=omega<2>R / g, and g is the gravitational acceleration. The practical inclination angle alpha obtained through calculating is treated as the measured inclination angle of the working platform. The method and the apparatus allow the inclination angle of the working platform to be accurately measured during the rotation of the working platform, so a problem that the measured inclination angle is less than the practical inclination angle value because of the omitting of the influence of the centripetal force during the rotation of the working platform in the prior art is solved.

Description

technical field [0001] The invention relates to an angle measurement method and device, in particular to a method and device for measuring the inclination angle of a working platform. Background technique [0002] Since the climbing platform fire truck is a comprehensive special equipment integrating fire fighting, emergency rescue, high-altitude spraying and high-altitude engineering operations, it must be ensured that its working platform is always in a horizontal state, so as to ensure the safety of the staff on the working platform , so it is essential to level the working platform. To level the working platform, it is first necessary to accurately measure the inclination angle of the working platform. [0003] At present, in the process of measuring the inclination angle of the working platform, the inclination sensor is frequently used. The inclination sensor is used for the level measurement of the system or the measurement of the variation of the inclination angle r...
