Stage theater encoder

The stage theater encoder consists of a photoelectric code disc with a shaft in the center, on which there are circular and dark engraved lines, and is read by photoelectric transmitting and receiving devices to obtain four sets of sine wave signals combined into A, B, C, D, Each sine wave has a phase difference of 90 degrees (relative to a cycle of 360 degrees). The C and D signals are reversed and superimposed on the A and B phases to enhance the stable signal; in addition, a Z-phase pulse is output per revolution. Represents the zero reference position. Since the phases A and B differ by 90 degrees, the encoder's forward and reverse rotation can be judged by comparing the phase A or the B phase. The zero reference position of the encoder can be obtained through the zero pulse.

The materials of the encoder code disc of the stage theater include glass, metal, plastic. The glass code disc is a thin scribe line deposited on the glass, which has good thermal stability and high accuracy. The metal code disc is directly scribed with and unconnected, which is not easy But because the metal has a certain thickness, the accuracy is limited, and its thermal stability is an order of magnitude worse than that of glass. The plastic code disc is economical, and its cost is low, but the accuracy, thermal stability, and life are required. Worse.

Resolution—The number of open or dark engraved lines provided by the stage theater encoder per 360 degree rotation is called resolution, also known as resolution indexing, or directly called the number of lines, generally 5 to 10,000 lines per revolution.
