Abstract

The invention discloses a method for correcting north reference precision of an electronic compass. The method for correcting the north reference precision of the electronic compass comprises steps as follows: step 1, the electronic compass is fixed in a normal working area of a system electric appliance where the electronic compass is located, and the electronic compass and the system electric appliance are powered on for normal work; step 2, precision correction of north reference of the electronic compass is carried out. According to the method for correcting the north reference precision of the electronic compass, the problem that the precision of the electronic compass in the prior art can be decreased when the electronic compass as an accessory is used in certain electric appliance environment is solved, and precision adjustment of the electronic compass is realized.

Description

technical field [0001] The invention relates to the field of correcting the northing accuracy of an electronic compass, in particular to a method for correcting the northing accuracy of an electronic compass. Background technique [0002] The electronic compass in the present invention refers to an electronic device with north-pointing performance, and the north-pointing performance of the electronic device is easily affected by the surrounding electrical environment. At present, most of the electronic compasses popular in the market, when they are used as an accessory in a certain electrical environment (for example, the present invention will take the electronic compass as a north pointing accessory of a display module as an example), indicate In this case, how to ensure the accuracy of the north performance of the electronic compass. Contents of the invention [0003] The purpose of the present invention is to provide a method for correcting the northing accuracy of an...
