The present invention relates to a vehicle intelligent rail coating device intelligent control system which can realize the automatic and intelligent control of a coating device during a whole working process. The intelligent control system is based on an embedded Linux operation system and an ARM9T processor platform as a basic platform system. A curved conduit starting point/terminal position information memorizer, a keyboard/display, a signal feedback/control circuit and a control software module are connected with the basic platform system. A hydraulic pump driving control unit, a directly fusing/warming and heating control unit, a feedback detection unit, a TAX2 public information interface unit and a GPRS remote digital transmission module are also connected with the basic platform system. The device has the functions of identifying curves during operating process automatically, controlling coating work automatically, and the like, and the spraying process is unattended; the device can also realize the functions of monitoring the spraying process, data exchange, and the like, by a GPRS mobile data transmission technology.
