Reappearing method and system controlling river reach ship traveling dynamic and signal revealing process

Abstract

The invention discloses a reappearing method and a system for controlling river reach ship traveling dynamic and signal revealing process. The reappearing method comprises the following steps: collecting real-time information of dynamic and static information (automatic identification system (AIS) data and radar data) and videos of a traveling ship, very high frequency (VHF) call voice, signal tower command information and the like; compressing and storing the collected real-time information; and receiving reappearing orders, starting playback reappearing procedures, selecting a ship or a time quantum for playback reappearing, loading historical information, synchronously displaying information of ship positions corresponding to audios and videos, ship dynamic historical route, signal revealing time point, and the like. According to the reappearing method and the system, historical information of arbitrary come-and-go ships or within a time quantum can be found and used for synchronous playback, original record information of the audios and videos, ship dynamic tracks, signal revealing orders, and the like can be synchronously displayed in the whole course, and thus dynamic relevant evidence of the ship traveling dynamic and the signal revealing process is formed and can be used as a basis of accident analysis after an accident and signalman command effect evaluation.

Description

technical field [0001] The present invention relates to a method and system for storing, viewing and reproducing data for controlling ship passage and signal disclosure in a river section, and in particular to a synchronous reproduction method for controlling multi-source information association between ship passage dynamics and signal disclosure in a river section. Background technique [0002] The waterway in the upper reaches of the Yangtze River is narrow and curved, and the order of ship traffic is controlled by the signal station. The correct disclosure of the traffic signal of the signal station and the strict obedience of all passing ships to the command and dispatch of the signal station are important prerequisites for ensuring the safe passage of ships. However, there are still a small number of ships that do not obey the command orders of the signal station, and violate the regulations such as grabbing water and forcibly overtaking in the controlled river section,...

Problems solved by technology

These independent systems can save and replay the information of the monitored objects. Once a marine accident occurs, it is necessary to extract information from a large number of related records, and analyze and compare it by printing, viewing historical tracks, and watching videos. Manpower, time-consuming, accident causes and responsibilities are difficult to identify, and these records cannot form a dynamic chain of evidence that can be verified by each other, and cannot faithfully reproduce the entire process, and cannot play back the accident process in the control section, analyze the cause of the accident, and Accident Liability Provides Strong Scientific Support
