Problems solved by technology
[0002] The mobile phone can be equipped with a laser generator, and the processor on the mobile phone can control the laser generator to emit laser light. However, when the processor of the mobile phone fails and crashes, the laser generator may continue to emit laser light for a long time. The long-term emission of laser light is easy to hurt the user, especially the user's eyes

The invention discloses a control system of a photoelectric projection module. The control system includes a first drive circuit, a second drive circuit, a microprocessor and a watchdog timer. The first driving circuit is connected with the photoelectric projection module. The second driving circuit is connected with the first driving circuit, and the second driving circuit is used for supplying power to the first driving circuit. The microprocessor is connected with the first driving circuit and is used to control the first driving circuit to drive the photoelectric projection module to project laser light, and the microprocessor is also used to send predetermined signals. The watchdog timer is connected to the first driving circuit, the watchdog timer and the second drive circuit, and the watchdog timer is connected to the microprocessor. The watchdog timer is used for receiving a predetermined signal, and the watchdog timer is used for not receiving a predetermined signal within a predetermined period of time. , turn off the first driving circuit and the second driving circuit to turn off the photoelectric projection module. The invention also discloses a photoelectric projection component, a terminal and a control method of the photoelectric projection module.
Description
Technical field[0001]The present invention relates to the field of consumer electronics, and more particularly to a control system of a photoelectric projection module, a photoelectric projection assembly, a terminal, and a photodetection module.Background technique[0002]A laser generator can be configured on the phone. The processor on the phone can control the laser generator to transmit a laser outward, however, when the phone's processor is faulty and crashing, the laser generator may continue to transmit the laser in the foreign time. Long-term laser is easy to hurt users, especially the user's eyes.Inventive content[0003]Embodiments of the present invention provide a control system of a photoelectric projection module, a photoelectric projection assembly, a terminal, and a photoelectric transfrance module.[0004]The control system of the photoelectric projection module of the embodiment of the present invention includes:[0005]The first driving circuit, the first driving circuit...
