Geography true north direction gauge

Abstract

The invention discloses a geography true north direction gauge which comprises a solar altitude angle gauge and a solar azimuth gauge. The solar azimuth angle gauge comprises a second shell body, a second motor, a second small gear shaft, a second small gear, a second large gear shaft, a second large gear, a second turn angle detecting unit and a second signal processing and displaying unit for converting detected signals by the second turn angle detecting unit to a solar azimuth angle value. The upper end of the second large gear shaft penetrates through the upper portion of a second shell body. The solar altitude angle gauge comprises a first shell body fixedly arranged on the second large gear shaft, a first motor, a first small gear shaft, a first gear, a first large gear shaft, a solar photovoltaic board, a first turn angle detecting unit and a first signal processing and displaying unit. The geography true north direction gauge is simple in structure, convenient to install and arrange, low in cost, convenient to operate, high in testing precision, and capable of effectively solving the problems that a traditional geography position orientational testing device is complex in whole structure, high in cost, not capable of storing data when measurement is performed in outage and the like.

Description

technical field [0001] The invention relates to a surveying instrument, in particular to a surveying instrument for the geographical true north direction. Background technique [0002] When people are in an unfamiliar environment, they often have no sense of direction, especially for geological surveys, mountaineering, crossing forests or deserts, etc., it is very important to correctly distinguish the direction. Rough reference direction; and some fields with strict direction requirements, such as detection and other technical fields, often use GPS locators and measurement modules to determine the direction, but the above measurement methods have low accuracy and are susceptible to magnetic fields to varying degrees. Due to defects such as interference, it is impossible to achieve accurate orientation of the geographical location. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a geographical true north directi...
