Title:
CONTROL SYSTEM FOR LASER PROJECTOR AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2019/228019
Kind Code:
A1
Abstract:
A mobile terminal (100) and a control system (30) for a laser projector (10). The control system (30) comprises a first driving circuit (31), a second driving circuit (32), a monitoring timer (34), and a microprocessor (35) and an application processor (33) which are connected to the monitoring timer (34). The first driving circuit (31) is connected to the laser projector (10) and used for outputting an electric signal to drive the laser projector (10) to project laser. The second driving circuit (32) is connected to the first driving circuit (31) and used for supplying power to the first driving circuit (31). The monitoring timer (34) is connected to the second driving circuit (32). The microprocessor (35) is used for transmitting a first predetermined signal to the monitoring timer (34). The application processor (33) is used for transmitting a second predetermined signal to the monitoring timer (34). When the monitoring timer (34) fails to read the first predetermined signal or the second predetermined signal, the monitoring timer (34) turns off the second driving circuit (32) so as to turn off the first driving circuit (31) and the laser projection module (10).
