Method and device for recording, analyzing and live-broadcasting driving commands

Abstract

The invention relates to a method and device for recording, analyzing and live-broadcasting driving commands, and the method comprises the steps: 1), carrying out the dynamic image modeling of varioustypes of state significance of railway signal equipment and a driving plan diagram, and defining the standardized flow of driving operation and command words; 2) receiving an HDMI / VDI digital video signal output by an operation terminal and converting the HDMI / VDI digital video signal into an RGB image; collecting a voice instruction of a commander; 3) performing retrieval and analysis of abnormal operation and key process operation on the images, the voices and the characters; 4) encoding, compressing and packaging related images and voices, and adding corresponding voice subtitles to form avideo file set; 5) performing multi-channel synchronous playback on the formed video file set, and 6) performing video coding packaging on the images and the voices formed in the step 2), and pushingthe images and the voices to a video live broadcast system. Compared with the prior art, the method has the advantages that the comprehensive analysis capacity of operation behaviors and the emergency processing capacity of dispatching and commanding are improved, and the like.

Description

technical field [0001] The invention relates to the monitoring, retrieval and analysis technology of operation behavior in the railway transportation process, in particular to a method and device for recording, analyzing and live broadcasting of traffic command. Background technique [0002] Safety and efficiency are the two eternal themes of traffic command. The achievement of these two themes mainly depends on the functional integrity of the traffic command equipment and the operation level of the dispatching command personnel, especially in emergency situations. The application of TDCS3.0 and CTC3.0 has realized the error alarm and safety card control of driving operations such as pick-up and departure at the system level, and has reached a new level in terms of safety command. In terms of the operation level of dispatching and commanding personnel, the dispatching and train service training simulation system is being developed and applied. Its main purpose is to improve...

Problems solved by technology

The method includes: collecting CTC signal equipment status change information, interlocking route sequence information, CTC operation alarm information, and dispatcher operation information; identifying and analyzing the collected data, and retrieving operational behaviors with hidden dangers and behaviors Generate relevant alarms, establish the correlation between operation behaviors and alarms; automatically analyze the status change information of signal equipment, and identify specific operation behaviors with hidden dangers; filter out the records of dangerous operation behaviors in the non-production state of construction and drills; through The data visualization method of the chart visually displays the statistics of dangerous and hidden operation behaviors; it provides a one-key playback function for the retrieval and analysis process, and playbacks relevant information when the operation behavior occurs, including signal equipment status change information, route sequence change information, The alarm change information is used to truly restore the on-site situation when the operation behavior occurs; this patent can identify certain improper operation behavior and analyze the operation behavior, but it has certain limitations, which are reflected in: 1) The method generates CTC The alarm information is a clue, and the scope of its behavior retrieval depends on the type of alarm information and the integrity of the information. In the case of incomplete alarm information and a tDCS system without alarm information, it is impossible to identify unreasonable operation behaviors, such as scheduling commands. related searches

2) This method cannot record and replay the operation process of the operator, and cannot replay the menu operation and button operation, that is, it does not know how the operator operates, which is not conducive to specific analysis of operation behavior and habits

3) This method can only play back the station map, and cannot record other terminal scenes related to the operation, so it cannot be played back, and the logical correlation before and after the operation cannot be analyzed

4) This method does not record the voice command instructions of the operator, and cannot perform standardized recognition of the command instructions

5) This method cannot realize the live broadcast of on-site operation, and cannot complete the remote command function
