Abstract: The present invention discloses a real-time on-site image relay system of a mobile work vehicle. The real-time on-site image relay system of a mobile work vehicle includes: a camera which is mounted on the vehicle to record the road state, adjusts the photographing rotation angle and the zoom features according the motor operation, convert the recorded image to a digital signal and send the digital signal to a work vehicle terminal; the work vehicle terminal which is mounted on the vehicle to send the image data received from the camera and the location data received from the GPS to a management server, and controls the photographing rotation angle and zoom features of the camera; a weather server which provides the weather information to the management server; and the management server which outputs the received information to a display unit. [Reference numerals] (AA) Start; (BB) End; (S11) Step for storing in a DB by registering a work vehicle and the work area information, snow removal quantity information, map information, and road information allocated in each work vehicle into a management server; (S12) Step for converting into a winter mode, a summer mode, or a normal mode by a mode switch unit of the work vehicle terminal and transmitting a switching result to the management server; (S13) Step for receiving the weather information from a weather server to the management server; (S14) Step for calculating the snow removal quantity based on the received weather information, the allocated work area information, and the road information by the management server and providing to the work vehicle terminal; (S15) Step in which the work vehicle moves to the road of the work area and the mode switch unit of the work vehicle terminal is switched to a work mode; (S16) Step in which a camera installed in the work vehicle photographs the road, switches into a digital signal, and transmits to the work vehicle terminal; (S17) Step in which the work vehicle terminal determines whether the received road image is the road in which the snow is removed; (S18) Step in which the work vehicle terminal transmits the snow removal road image information, location information, and time information to the management server; (S19) Step in which the management server stores the received road image information with the location and time information in an image DB; (S20) Step in which the management server calculates a road work area in which the snow removal work is completed and stores in the snow removal work amount DB; (S21) Step for mapping the snow removal completion road area information of the work amount DB with a map DB; (S22) Step for expressing the mapped map information through a display unit; (S34) Step in which the management server receives the weather information from the weather server; (S35) Step in which the work vehicle terminal moves to the work area road in a flooded area and switches to the work mode; (S36) Step for photographing the flooding and inundation area after adjusting the rotation angle and distance of the camera attached in the work vehicle, switching to the digital signal, and transmitting to the work vehicle terminal; (S37) Step in which the work vehicle terminal compares the image information received from the camera with the previously stored flooding and inundation image information and determines whether the received image is the flooding and inundation image; (S38) Step in which the work vehicle terminal transmits the flooding and inundation image information, location information, and time information through a transmission module to the management server; (S39) Step in which the management server stores the received flooding and inundation image information, location information, and time information in a flooding image DB and expresses through the display unit; (S44) Step in which the work vehicle terminal moves to the road of the work area and switches to the work mode; (S45) Step for switching into the digital signal after photographing the road surface by adjusting the rotation angle of the camera attached in the work vehicle, switching into the digital signal, and transmitting to the work vehicle terminal; (S46) Step in which the work vehicle terminal compares the received road surface image information with the road damage image information previously stored in a road damage DB and determines whether it is the road damage image information; (S47) Step in which the work vehicle terminal transmits the road damage image information, location information, and time information to the management server; (S48) Step in which the management server stores the received road damage image information, location information, and time information in the road damage image information and expresses through the display unit
