Traffic guidance screen monitoring method

Abstract

The invention provides a traffic guidance screen monitoring method, which comprises at least one transition scene used for being displayed on a guidance screen. The transition scene comprises a plurality of transition detection frames; when the guidance screen is normal, each display module on the guidance screen is turned on at least once and turned off at least once during the display process ofthe transition scene; the actual picture is identified and processed, each display module on the guidance screen is turned on at least once and turned off at least once in the actual picture group; otherwise, the display module which is not turned on or not turned off breaks down. The method is convenient to implement and is low in cost, whether the guidance screen has the display fault or not can be rapidly found, the positions and the number of the fault points on the guidance screen can be rapidly determined, and therefore the equipment maintenance efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a traffic guidance screen monitoring method. Background technique [0002] At present, with the continuous development of cities, the use of inductive screens is becoming more and more common in the field of transportation, and the content displayed on the inductive screens not only has the functions of prompting, early warning and road guidance, but also has the functions of publicizing and enlightening urban civilization. role. At present, the guiding screen is used to control the industrial computer to send the display content such as text, pictures, and video to the traffic guiding screen and display it. The content information includes real-time traffic guiding information, which can divert traffic from vehicles and improve traffic efficiency. [0003] With the increasing complexity of urban traffic conditions, the distribution of guidance screens is more extensive, and the...

Problems solved by technology

As a result, when an abnormality occurs on the traffic guidance screen, there is a lack of an exception handling mechanism. As a result, when an abnormality occurs on the traffic guidance screen, the maintenance personnel cannot be notified in time of the abnormal state. In addition, the maintenance personnel need to go to the actual scene to correct the traffic guidance screen. Make correct judgment and processing of the screen status, and the work efficiency is not high

[0005] Under normal circumstances, a guiding screen is composed of multiple display modules. When a display module fails, it will also cause the guiding content to fail or be distorted, losing the role of guiding and indicating.

In the prior art, a point-by-point detection device can be installed inside the display module, which can monitor whether each display module is normal at any time. However, the price of the induction screen equipped with the point-by-point detection module is relatively high, and all the induction screens used on the traffic road should be replaced. Expensive and cannot be implemented quickly
