Description

The present invention relates to a monitoring control device that photographs a vehicle traveling in the lane of a tollhouse, accumulates captured images, and performs remote monitoring.

A camera that captures images of vehicles passing through ETC (Electronic Toll Collection) lanes, a video recording device that records captured vehicle images, and detection of vehicle contact with a blocking bar as it passes through an ETC gate. It is equipped with a bar contact sensor that detects the vehicle leaving the ETC lane, and collects the illegal traffic information for each illegal traffic block from the bar contact time to the ETC lane exit time in the illegal traffic information database. There is known a monitoring control device that searches for and displays an image of an illegally passing vehicle from a recorded image based on illegal traffic information (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2007-265322

The monitoring and control device of the centralized tollhouse aggregates the lane monitoring camera image information for each of up to 10 tollhouses and performs remote monitoring. The video storage device that stores the lane monitoring camera video information of each toll station is not placed in the lane monitoring control device on the aggregated side that collects the video information for each lane, but on the aggregated toll station side that collectively manages the collected information. Installed on the center server. Therefore, if a communication network failure occurs between the lane monitoring and control device on the aggregated side and the center server on the aggregated tollhouse side, or if the image storage device on the center server fails, the video information will be displayed. There was a problem that the camera images of all the tollhouses to be aggregated could not be accumulated.

In addition, since the lane monitoring camera image of the toll station where the video information is collected is always sent to the center server on the side of the toll center, there is a problem that the transmission band required for video information transmission becomes large.

The present invention has been made to solve the above problems, and is necessary for video information transmission while enabling storage of lane surveillance camera images even if a communication network failure or a failure of the image storage device occurs. The purpose is to suppress the transmission band.
