Position pulse generation device, system and method based on absolute encoder

The invention relates to the technical field of pulse generators, in particular to a position pulse generation device, system and method based on an absolute encoder. The device is arranged on a rotary table carrying photoelectric equipment, and comprises an absolute encoder and a circuit board, the circuit board comprises an encoder receiving circuit, an FPGA chip, a differential pulse transmitting chip, a serial port transceiving circuit, an FPGA configuration circuit and a power supply circuit; the FPGA chip is used for receiving an angle signal sent by the encoder receiving circuit in real time, when the current angle reaches an adjacent interval, the angle of the rotary table is predicted based on the current angle, a fixed angle required by photoelectric equipment and the rotating speed of the rotary table, and a first pulse signal is sent to the differential pulse sending chip until the rotary table is predicted to reach the fixed angle; therefore, the differential pulse sending chip sends out a target
