Description

Technical Field

[0001] The utility model relates to the technical field of electronic markings, in particular to a road traffic sign. Background Art

[0002] The dust monitor monitors the dust environment of the highway traffic construction project site through other devices such as wind speed sensors installed at the detector, and the monitored data will be displayed on the electronic display sign installed on one side of the detector for clear viewing. However, the clarity of the electronic display sign gradually decreases over time, affecting the clear display of the monitoring results.

[0003] The main reason for the above problems is that the electronic display signboard installed on the outer surface of the dust detector is directly exposed at the construction site, and the highway traffic project will generate dust during the construction process. Therefore, dust and the like continue to adhere to and accumulate on the surface of the electronic display signboard, thereby blocking the electronic display signboard, and the electronic display signboard is not equipped with a dust cleaning device, which affects the clear display of the monitoring results on the electronic display signboard. In response to the above situation, we propose a road traffic sign. Utility Model Content
