Description

Technical Field

[0001] This utility model relates to the field of display device technology, specifically to a visualization library-side digital display device. Background Technology

[0002] A warehouse is a place specifically used for storing and preserving materials, goods, or finished products. Warehouses can be classified according to the form of the stored items as warehouses for storing solid items, liquid items, gaseous items, and powdered items. In warehouse management, it is necessary to know the material inventory level inside the warehouse in real time.

[0003] Common measuring tools include laser ranging, ultrasonic ranging, radar ranging, and level gauges. Laser ranging calculates material height by emitting a laser beam and using the time it takes for the laser to reflect back from the material. Ultrasonic ranging calculates material height by using the time it takes for ultrasonic waves to travel through the material. Radar ranging measures material height by emitting radar signals into the material and calculating the time it takes for the signals to reflect back and the signal strength. Level gauges detect material height using sensors. All of these methods use display devices to show the material height data.

[0004] However, since the display device is installed on the outside of the warehouse side and exposed to the air, dust accumulates on the display device and needs to be cleaned before it can continue to be used. Since the display device is installed at a high position, it requires additional tools to clean it, which is quite troublesome. Therefore, a visual warehouse side digital display device is proposed.
