The invention discloses a linkage signal acquisition system and an intelligent identification method based on video streaming, and the acquisition system comprises a computer linkage system, a train dispatching command system, and a linkage signal and driving log information acquisition device. The chain signal and driving log information acquisition device comprises a first VGA distributor, a second VGA distributor and a high-definition video encoder. According to the interlocking signal acquisition system, a channel special for video information transmission is branched out through the VGA distributor, instead of obtaining video information by shooting a display of a computer interlocking system, so that internal and external interferences are greatly reduced or shielded. The linkage signal intelligent identification method comprises the steps of system initialization, signal change detection and signal area type matching, signal state identification based on the signal area type, linkage signal processing and recording and the like, and intelligent, accurate and efficient identification of the linkage signal based on the video stream is achieved.
