The invention relates to equipment for monitoring the state of a coke oven gas plug valve, the equipment comprises a plug valve state indicating device and a position measuring device, the position measuring device comprises a distance measuring instrument M1 and a distance measuring instrument M2, the two distance measuring instruments are arranged in an oblique alignment plane mode, and laser or infrared light for distance measurement is emitted in the arrangement direction of a gas plug valve pipeline. The light rays respectively irradiate to a vertical forward or reverse indication reflecting plate mounted on the plug valve, and the vertical distances from the light rays to the supporting rod are equal; according to the technical scheme, the state mark of the plug valve is amplified, so that the on-off state of the valve can be identified conveniently; and the range finder equipment is adopted, so that a test area can be covered in a large range, and the application of a large amount of explosion-proof de
