Coke-oven vehicle-position measuring device

The invention discloses a coke-oven vehicle-position measuring device, which comprises a detecting device and an accurate-positioning code plate, wherein the detecting device is fixedly arranged on an outer vehicle body, and the accurate-positioning code plate is matched with the detecting device for use and is fixed along a vehicle track; a slotting area is arranged on the positioning code plateand is used for representing vehicle corresponding-position information; the detecting device is used for detecting the vehicle corresponding-position information on the code plate and comprises an infrared transmitting unit, an infrared receiving unit, a positioning-identifying unit and a modulating and signal-converting unit; and the positioning-identifying unit is used for detecting the existence of the positioning code plate and sending out an existence signal to the modulating and signal-converting unit which is connected with the positioning-identifying unit, the modulating and signal-converting unit is used for recording light-source information received by the infrared receiving unit while opening the infrared transmitting unit and the infrared receiving unit, and the light-sourceinformation is transmitted into a control center after being converted into binary digital information. The position measuring device has the advantages of simple structure, firmness, durability and high precision, and because the cost of the position measuring device is low, the position measuring device is suitable for being widely popularized in the field of track-vehicle position detection.
