Description

Waterproof magnetic grid ring module

technical field

The invention relates to the technical field of magnetic grid ring modules, in particular to a waterproof magnetic grid ring module.

Background technique

At present, there are generally the following methods for measuring the rotational angular velocity. 1. The principle scheme of the direct counting system. When the grating moves a pitch angle, the counting circuit sends a counting pulse, which is counted and decoded by the reversible counter; 2. , When the grating moves a pitch angle, the subdivision circuit can send out N pulses equal to the number of subdivisions, which are counted and decoded by the reversible counter. At this time, the current more common scheme; 3. The grating signal is separated by the separation circuit to separate the integer counting pulse and the decimal counting pulse, and then send the comprehensive counting pulse through the integer technology encoder and sensor respectively, and the reversible counter performs comprehensive counting and decoding display. This scheme is suitable for fast measurement, but the current three measurement schemes all have certain defects, especially in terms of waterproofing. Therefore, a waterproof magnetic grid ring module is urgently needed.
