Overheat protection system of electronic equipment, electronic equipment and control method

Abstract

The invention discloses an overheat protection system of electronic equipment, the electronic equipment and a control method. The overheat protection system comprises a TOF module, a temperature acquisition module for acquiring a first temperature signal of a common-temperature area around the TOF module, and a control module for controlling the working state of the TOF module or controlling the working states of the TOF module and other parts in the electronic equipment. Under the condition that the temperature sensor is arranged in the TOF module to detect and feed back the internal temperature of the TOF module, the overheat protection system is arranged in the common-temperature area around the TOF module and other parts in the electronic equipment, the temperature of the common-temperature area is detected and fed back, dual protection of the TOF module is achieved, and the condition that the electronic equipment is damaged due to overhigh temperature of the common-temperature area or the internal temperature is prevented. The overheat protection system has universality, can be applied to various electronic equipment using the TOF module, and is simple in design, low in cost and convenient to widely apply.

Description

Technical field [0001] The present invention relates to the field of electrothermal protection, and more particularly to an overheating protection system, an electronic device and a control method of an electronic device. Background technique [0002] With the continuous development of technology technology, in all things, artificial intelligence, Ar / VR, and 5G communication technology, 3D imaging is increasingly attached to people, because 3D information can provide people more real world Information, this is not available in 2D information. Therefore, techniques for ranging from TOF and obtain 3D information are widely used in 3D imaging. However, TOF mainly uses active light sources, whether it is LED or laser, a heat source in operation, but overheating not only affects the working performance of electronic products, but also causing safety accidents, such as short circuits in electronic circuits, or batteries. Explosion and other risks. In addition, the active 3D camera is...
