In the process of performing underwater tasks, divers generally use the signal rope as the main communication tool, that is, by pulling and shaking the signal rope to form a series of signals to realize simple communication on land  This communication method is convenient and direct, but its disadvantages are also obvious: the signal rope can only realize the expression of limited information  Moreover, the signal transmission process is easily interrupted or failed due to the influence of complex seawater environment, which brings potential safety hazards  In 2015, there was a diver's signal rope entangled and almost an accident  It can be said that the diver's life hangs on a line when performing underwater tasks
In view of many disadvantages of the signal rope, combined with the rapid development of intelligent wearable devices in the civil field, intelligent wearable products for military diving have gradually become one of the research and development hotspots of scientific and technological workers
Development status of intelligent wearable devices in daily life
