A rail transit display information filtering device and method, and an information display system

Abstract

The invention provides a rail transit display information filtering device and method and a rail transit information display system. The device comprises a signal input interface, a data collector, aprocessor and a signal output interface; and the signal input interface is connected with a video matrix in the rail transit information display system and the data collector, the signal output interface is connected with display terminals. According to the independent rail transit display information filtering device, by arranging the devices between the video matrix and the display terminals toconduct bad information recognition and interception on to-be-displayed rail transit information in real time, bad information can be filtered, the real-time on-line visual protection effect is achieved, and control over video playing is improved; the device is convenient to use and has the plug and play advantage, follow-up overhauling, maintenance and upgrading of the device are convenient, andthe devices do not occupy resources of the video matrix or occupy resources of the display terminals when the devices filter the rail transit information.

Description

technical field [0001] The invention relates to the technical field of information monitoring equipment, in particular to a rail transit display information filtering device and method, and an information display system. Background technique [0002] At present, with the rapid development of the electronic information society, in people's daily life, various display devices can be seen everywhere as public electronic screens, in commercial buildings, office buildings, schools, hospitals, stadiums, stations, airports and other places All kinds of electronic screens can be seen everywhere. The public electronic screens are mainly used for policy promotion, business promotion, information dissemination, teaching demonstration, etc. Obviously, public electronic screens have become an important source of public visual information in people's daily life. The establishment of public electronic screens facilitates people's lives, increases publicity channels, and enables people to g...

Problems solved by technology

However, due to the lack of supervision on the playback content, when the topmost PIS communication network, or the intermediate video display network is attacked, or human error occurs, it may cause bad information to be displayed on the display facing the public. For example, in 2012, Beijing Metro No. 5 Line, because of the misoperation of the staff on duty, all the monitors of all the stations of the entire Metro Line 5 displayed the four characters "Wang Peng, Your Sister", which lasted for half an hour. This incident had a great adverse effect

[0005] Therefore, considering that the rail transit information display system in related technologies mainly avoids displaying rail transit information containing bad information through the management and control of managers, there may be rail transit information containing bad information due to the participation of human factors or other uncontrollable factors. erroneous playback, did not use technical means to control, and did not take final precautions at the moment before the display of rail transit information, resulting in poor controllability of the display of rail transit information containing bad information
