Abstract

The invention discloses a video state detection and checking method. The video request information is fully considered, and time-frequency access analysis is carried out on the video channel, so thatthe checking and classification of the video channel can be realized. On the basis that the network bandwidth of a video integration unit is acquired, the checked video channel is pre-estimated, the video state detection efficiency is effectively improved, and network bandwidth occupation caused by circulation polling of all video points is avoided; meanwhile, all operations can be subjected to data synchronization on the video platform side and remote operation and maintenance, when there is a problem, operation and maintenance personnel can be arranged to precisely locate the faulty video channel, and the operation and maintenance efficiency can be effectively improved.

Description

technical field

[0001] The invention belongs to the technical field of video monitoring, and in particular relates to a method for detecting and checking video states. Background technique

[0002] Traditional road monitoring is mainly based on fast dome monitoring, and the monitoring points are distributed at urban road intersections and key road sections where traffic and people flow are relatively concentrated; each intersection will promptly transmit the real-time images of the monitored area back to the large screen of the traffic command center (monitoring Office), so that the traffic command personnel can grasp the traffic conditions of each intersection and road section in real time, such as: the flow of people and vehicles on the road section, whether the signal lights are working normally, whether there are violations and traffic accidents. This information can help traffic management departments take appropriate measures in a timely manner.
