Improved low-temperature automatic heating device suitable for intelligent terminal

Abstract

The invention provides an improved low-temperature automatic heating device suitable for an intelligent terminal, and the device comprises an obtaining module which is used for obtaining environment temperature information, determining a first heating temperature value if the environment temperature information is smaller than first preset environment information or larger than second preset environment information, and determining a second heating temperature value if the first heating temperature value is smaller than the second heating temperature value; when it is judged that the environment temperature information is smaller than or equal to second preset environment information, a dynamic second heating temperature value is generated according to the environment temperature information; the generation module is used for acquiring the type information of the intelligent terminal and the area information and the thickness information of the heating film to generate heat loss information; the determining module is used for determining a first heating voltage of the heating film according to the first heating temperature value and the heat loss information, and determining a second heating voltage of the heating film according to the second heating temperature value and the heat loss information; and the control module is used for controlling a low-temperature-resistant battery to supply power to the heating film according to any one of the first heating voltage and the second heating voltage.

Description

technical field

[0001] The invention relates to the technical fields of handheld terminals and intelligent control, in particular to an improved low-temperature automatic heating device suitable for intelligent terminals. Background technique

[0002] The operating temperature of industrial intelligent terminal LCD screens is 0°C to 50°C, and the storage temperature is around -20°C. There are abnormal phenomena such as a blurred screen and the machine cannot be started.

[0003] Therefore, in low temperature conditions, in order to ensure that the smart terminal can work normally, it is necessary to automatically detect the smart terminal in a low temperature environment, and heat the smart terminal when the temperature is low. During the heating process, smart terminals generally use heating film for heating.

[0004] In the actual production and use process, the size and model of each device in different types of smart terminals are different. Different heating films ne...
