Abstract

The invention discloses an antenna attitude angle measuring method. The measuring method includes the steps: 1 fixing a sensor, and determining the measuring direction of the sensor; 2 measuring displacement between the sensor and a point on an antenna by the sensor along with fixed direction; 3 rotating the antenna, and continuing to measure displacement between the sensor and the point on the antenna by the sensor along with fixed direction; 4 calculating rotating direction angles of the antenna by the aid of the displacements measured in the steps. According to the measuring method, azimuth angles of the antenna are measured by the aid of a stroke conversion method, tilt angles of the antenna are measured by a tilt angle sensor, so that the antenna attitude angles can be measured, magnetic interference is avoided, continuous working and power supply of a system are omitted, a GPS (global positioning system) or other wireless positioning signals are omitted, and the measuring method is widely applicable to various external environments.

Description

technical field [0001] The invention relates to the field of antenna attitude angle measurement, measurement and control, in particular to an antenna attitude angle measurement method. Background technique [0002] At present, there are several test methods for antenna attitude angle: [0003] 1. Use the MEMS tilt sensor combined with the electronic compass to measure the attitude angle of the antenna. The electronic compass is a device that determines the direction angle by measuring the change of the earth's magnetic field. It is easily interfered by metal iron and other magnetic conductors. The method of on-site magnetic correction is not operable during construction and application. Therefore, this measurement method is used in common iron towers. The accuracy is not high in the antenna environment, and the application is limited. [0004] 2. Use MEMS inclination sensor combined with gyroscope to measure antenna attitude angle. By continuously integrating the angular ...
