System and method for monitoring outdoor display screen by using video image and/or digital photo

A video image and image monitoring technology, applied in closed-circuit television systems, transmission systems, static indicators, etc., can solve the problem of not being able to visually display whether the outdoor display screen is working normally, unable to identify the display effect and image of the outdoor display screen, and unable to improve Maintain timeliness and initiative, etc., to achieve the effect of improving normal and effective operation, promising prospects for promotion and application, and reducing maintenance costs

Problems solved by technology

However, when there is a problem with the device itself or the LED is in a critical working state, the fault cannot be detected
In particular, this detection method cannot provide an intuitive display, and cannot identify the actual display effect and image of the outdoor display screen
Furthermore, the outdoor display screens work outdoors all year round. Once a fault occurs, the construction and maintenance departments cannot proactively find out the problem with the equipment. Nowadays, pedestrians or drivers basically call the city government after seeing a problem with the outdoor display screen. Or the complaint telephone of the traffic management bureau, and then the receiving agency will pass it on to the maintenance and construction unit. The maintenance and construction performed are only passive maintenance of equipment, which cannot improve the timeliness and initiative of maintenance.
In short, in terms of actual detection and maintenance effects, the existing technology can neither visually display whether the working status of the outdoor display screen is normal, nor can it provide visually displayed videos and image photos for judging whether the content displayed on the outdoor display screen is consistent with the system release. Whether the content of the LED is consistent, and whether there will be political problems due to abnormal work of the light-emitting diodes or being used by bad guys

Abstract

The invention relates to a system and a method for monitoring an outdoor display screen by using a video image and / or a digital photo. The system is provided with an image acquisition device, an image monitoring device and a communication device, wherein the image acquisition device is arranged on the front side of the outdoor display screen; and the image monitoring device is connected with the image acquisition device and is provided with an intelligent image identification module, a communication protocol processing module and an intelligent judging and comparing module. The monitoring method comprises the following steps that: the image acquisition device shoots a display content of the outdoor display screen in real time and transmits the shot video and / or digital photo to the image monitoring device; the image monitoring device carries out two types of identification of a point-to-point lattice or an integrated image-text content on the video or the digital photo, and compares aprocessed display screen image lattice file with the original image file of a control center to judge whether the display screen image lattice file is displayed correctly; if a display fault is found, the number of fault lattices is checked in detail to obtain the correct working rate of a light-emitting diode (LED) of the outdoor display screen and automatically generate an alarm signal; and thealarm signal is transmitted to the control center by the communication device, so that maintenance personnel eliminates the fault in time.

Description

technical field [0001] The invention relates to a system and method for monitoring an outdoor display screen by using video images and / or digital photos, and belongs to the technical field of wireless communication and remote control. Background technique [0002] With the development of urbanization in our country, the roads within cities and between cities are increasing rapidly, and all major large and medium-sized cities have built a large number of outdoor display screens above the main roads according to actual needs for notices Traffic conditions ahead or around. Because these outdoor display screens are in the working state of the outdoor natural environment all the year round, they need to withstand the test of various harsh environments such as high temperature, low temperature, wind, sun, rain and so on. At present, their work is to detect the working voltage and current of the control circuit of the internal light-emitting diodes to judge whether each light-emit...
