本文提出了三种简便易行的引偏方法:1.翻转法;2.换相法;3.注入信号法。只要根据当时当地的实际情况从中任选一种,便可做到不取掉外罩而使平台偏离。文中除概要地介绍了引偏程序之外,还对各种引偏方法的工作原理进行了简要分析。因此,本文对陀螺仪表的生产与维护有参考意义。 In this paper, three simple and easy methods for depolarization are proposed: 1. Flip method; 2. Commutation method; 3. Injection signal method. Just according to the actual situation at the time of the local election, you can do not remove the cover and make the platform deviate. In addition to a brief introduction of the depolarization program, the article also briefly analyzes the working principle of various depolarization methods. Therefore, this article is of reference to the production and maintenance of gyro meters.
