Document Type and Number:
WIPO Patent Application WO/2018/023949
Kind Code:
A1
Abstract:
An accurate temperature measurement integrated display device for accurate temperature-controlled fruit and vegetables storage comprises a sealed rigid PVC box (1), a 0.1°C resolution meteorological thermometer (2), a micro camera (3) with an adjustable focus, an LED infrared light source (4), a video transmission line (5), a video splitter (6), a display screen (7), and a 12 V DC power supply (8). A lid and a box body of the sealed rigid PVC box (1) are sealed with a sealing strip and a screw. The 0.1°C resolution meteorological thermometer (2) crosses the sealed rigid PVC box (1) and is fixed in the box by a lock. A scale position of 0°C is adjusted to a center position of the box (1). A camera lens of the micro camera (3) with an adjustable focus is pointed at the scale position of 0°C, and the temperature scales are clearly displayed by adjusting the focus. Four LED infrared light sources (4) connected in series are placed at a back side of a case of the thermometer (2). The video transmission line (5) transmits images captured by the micro camera (3) to the video splitter (6). The 12 V DC power supply (8) is used as a DC power supply of the micro camera (3) and the LED light source (4).
