High-precision turret angle measuring system and method free of power failure influence

The invention relates to a high-precision turret angle measuring system and method free of power failure influence, and belongs to the technical field of turret angle measurement. The invention designs the high-precision turret angle measuring system and method which are not affected by power failure, and the system and method have the following advantages: 1) because a turret angle measurement sensor is not limited by the matching of the number of teeth of a turret seat ring, the turret angle value of any seat ring can be collected by setting the number of teeth of the seat ring and the number of teeth of a speed increasing gear; and 2) the turret angle sensor is supported to rotate the turret under the outage condition, angle output is not affected by the outage rotating turret after theturret angle sensor is electrified again for use, the turret angle can be correctly output, and the function meets the service guarantee requirement. 本发明涉及一种不受断电影响的高精度炮塔角度测量系统及方法，属于炮塔角度测量技术领域。本发明设计了一种不受断电影响的高精度炮塔角度测量系统及方法，它具
