The invention discloses a mobile terminal and a laser projector control system. The control system comprises first and second driving circuits, a microprocessor connected with the first driving circuit and an application processor, the first driving circuit is connected with a laser projector, and outputs an electric signal to drive the laser projector to project laser. The second driving circuitis connected with the first driving circuit and supplies power to the first driving circuit. The application processor is connected with the microprocessor and the second driving circuit, reads a preset signal from the microprocessor, and switches off the second driving circuit so as to switch off the first driving circuit and the laser projection module when the preset signal cannot be read. In the control system, the micro processor is determined to have an operation fault when the application processor cannot read the preset signal from the microprocessor, the application processor switchesoff the second driving circuit so as to switch off the first driving circuit and the laser projection module, and the laser projector is prevented from emitting laser outwardly and doing harm to a user.
Description
technical field [0001] The invention relates to the technical field of consumer electronics, and more specifically, to a control system and a mobile terminal of a laser projector. Background technique [0002] A laser generator can be configured on the mobile phone, and the laser generator is used to emit laser light outward. However, when the mobile phone fails and crashes, the laser generator may continue to generate laser light for a long time, and the long-term emitted laser light is likely to hurt the user. , especially the user's eyes. Contents of the invention [0003] Embodiments of the present invention provide a control system and a mobile terminal of a laser projector. [0004] The control system of the laser projector of the embodiment of the present invention comprises: [0005] A first drive circuit, the first drive circuit is connected to the laser projector and is used to output an electrical signal to drive the laser projector to project laser light; ...
