Remote start-stop device of screw pump system

The utility model discloses a remote start-stop device of a screw pump system. The remote start-stop device solves the problem that the screw pump system has safety hazards in field starting and stopping. The remote start-stop device is composed of an emitting unit and a receiving unit, wherein the emitting unit comprises a starting switch, a stopping switch, an encoder and an emitting chip, the starting switch or the stopping switch inputs signals to an encoding chip of the encoder, the input signals are operated by the encoding chip and then input to the emitting chip, and the emitting chip emits encoding signals after encoding; and the receiving unit comprises a receiving chip, a decoder and a relay, the receiving chip receives the signals, decodes the signals and outputs the signals to a decoding chip of the decoder, and the decoding chip operates the signals and then drives the relay to control a screw pump to be started or stopped. The remote start-stop device is small in size, can achieve the aim of st
