Provided is a distress signal generator, relating to the technical field of emergency rescue equipment. The distress signal generator comprises a power supply (1), a trigger module (2), a power detection module (3), a switch (4), a control module (5), and a distress signal generation module (6). The power supply (1) comprises a mains supply and a backup battery, and the backup battery being used for supplying electricity after the mains supply is cut off. The power detection module (3) is used to detect whether the power supply (1) is powered by the mains supply or the backup battery. The switch (4) is closed when the power detecting module (3) detects that the backup battery is supplying electricity, so that the backup battery is connected to the control module (5); The trigger module (2) connects the power supply (1) and the control module (5) under external force to make the control module (5) work. The control module (5) is configured to control the distress signal generating module (6) to issue a distress signal. The distress signal generation module (6) is configured to issue a distress signal. The distress signal generator has a simple structure and low cost, and can automatically send a distress signal under a external force, so that the trapped person can be easily found by the rescue personnel, which shorten or reduce the search and rescue time, and reduce the casualties, with wide application range and high promotion value.
