Safety monitoring system and fatigue monitoring apparatus and fatigue detecting helmet thereof

A fatigue monitoring apparatus capable of being attached to a cap, the fatigue monitoring apparatus comprising:

• at least one first electrode for being in contact with a first position of a head, thereby obtaining a first physiological information;
• at least one second electrode for being in contact with a second position of the head, thereby obtaining a second physiological information, wherein the second position is farer from a brain of the head than the first position;
• a fatigue computation device capable of being disposed on one side of the cap, the fatigue computation device comprising a brainwave computation module and a fatigue determining module, wherein the brainwave computation module is electrically connected to the first electrode and the second electrode for obtaining a brainwave information based on the first physiological information and the second physiological information, wherein the fatigue determining module is electrically connected to the brainwave computation module for obtaining a fatigue information based on the brainwave information;
• and
• a power supply capable of being disposed on another side of the cap opposite to the fatigue computation device, wherein the fatigue computation device is electrically connected to the power supply.

A safety monitoring system comprising:

• a monitoring server having a first wireless communication module;
• and
• at least one fatigue monitoring apparatus attached to a cap, the fatigue monitoring apparatus comprising at least one first electrode, at least one 20 second electrode, a fatigue computation device and a power supply, wherein the first electrode and the second electrode are respectively in contact with different positions of a head for respectively obtaining a first physiological information and a second physiological information, wherein the fatigue computation device obtains a brainwave information based on the difference between the first physiological information and the second physiological information, and obtains a fatigue information based on the brainwave information, wherein the power supply is electrically connected to the fatigue computation device for providing power, wherein the fatigue computation device and the power supply are disposed on opposite sides of the cap, wherein the fatigue monitoring apparatus comprises a second wireless communication module;
• wherein the first wireless communication module is in wireless communication with the second wireless communication module, wherein the monitoring server receives the fatigue information from the fatigue monitoring apparatus.
