Automatic resetting device for angular displacement sensor of oil pumping unit based on oil field digitization

The automatic reset device comprises a solar photovoltaic panel, a wire, a power supply, a remote controller, a receiving controller, a box body, an electric cylinder, a magnet, the angular displacement sensor and the oil pumping unit, the device is characterized in that the solar photovoltaic panel is connected with the power supply through a wire, the power supply supplies power to the receiving controller through a wire, and the remote controller wirelessly and remotely controls the receiving controller to control the electric cylinder to rotate forwards or backwards through a wire, so that a push rod of the electric cylinder drives the front-end magnet to move leftwards and rightwards; the magnet moves leftwards to approach a reset switch of the angular displacement sensor, the angular displacement sensor is started to work, the power source, the receiving controller and the electric cylinder are installed in the box body, and the box body and the solar photovoltaic panel are installed on a walking beam o
