Electronic display screen on urban road sign

Abstract

The invention relates to the technical field of electronic display screens, and discloses an electronic display screen on an urban road sign, the electronic display screen comprises a stand column, the top of the stand column is fixedly connected with a fixing frame, and the electronic display screen is fixedly installed in an inner cavity of the fixing frame. A first servo motor is started to drive a C-shaped frame to move left and right, cleaning cloth and a roller can be further driven to move left and right, then a second servo motor is started to drive the roller and the cleaning cloth to rotate, and therefore dust on the surface of the electronic display screen can be cleaned through the cleaning cloth; and the display effect of the electronic display screen is further prevented from being influenced by dust, through the arrangement of a photosensitive sensor, when the light intensity is high, the brightness of the electronic display screen is higher, a driver can conveniently and clearly observe information on the electronic display screen in the daytime, at night, the brightness of the electronic display screen becomes dark, and therefore, the situation that the eyes of a driver are stimulated to cause accidents due to the fact that the electronic display screen is too bright can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of electronic display screens, in particular to an electronic display screen on an urban road sign. Background technique [0002] Simply put, the LED display screen is composed of several display units (unit display board or unit display box) that can be combined and spliced ​​to form a screen body, plus a set of appropriate controllers (main control board or control system). Therefore, display panels (or unit boxes) of various specifications can be combined with controllers of different control technologies to form many kinds of LED display screens to meet the needs of different environments and different display requirements. Indoor screens are generally made of aluminum alloy (angle aluminum or aluminum square tube) to form the inner frame, which is equipped with various circuit boards such as display boards and switching power supply. The size and load-bearing capacity are generally composed of angle st...

Problems solved by technology

Therefore, display panels (or unit boxes) of various specifications can be combined with controllers of different control technologies to form many kinds of LED display screens to meet the needs of different environments and different display requirements. Indoor screens are generally made of aluminum alloy (angle aluminum or aluminum square tube) to form the inner frame, which is equipped with various circuit boards such as display boards and switching power supply. The size and load-bearing capacity are generally composed of angle steel or I-beam, and the outer frame can be decorated with aluminum-plastic panels. The electronic display screens on the existing urban road signs are exposed for a long time, so a large amount of dust will be adsorbed on the display screen In addition, it will further affect the traffic personnel to observe the information on the display screen, and the brightness of the existing display screen is fixed. Only when the brightness of the display screen is brighter during the day can it be observed by the traffic staff. At night, the brightness of the display screen Brighter brightness will cause irritation to the eyes of drivers, and further cause accidents. Therefore, we propose an electronic display screen on urban road signs
