Electronic equipment and electronic equipment system applied to diving and control method of electronic equipment system

Abstract

An embodiment of the invention discloses a control method for an electronic equipment system applied to diving. The electronic equipment system applied to diving comprises master equipment and slave equipment. The control method is executed in the master equipment. The control method comprises the following steps that a positioning request signal is sent to the slave equipment through an ultrasonic transmitter; a feedback signal transmitted by the slave equipment is received by a plurality of ultrasonic receivers, wherein the feedback signal is generated by the slave equipment in response to the positioning request signal, and the feedback signal comprises water pressure data; the relative distance between the master equipment and the slave equipment is calculated out according to a time difference between sending time of the positioning request signal and receiving time of the feedback signal and the signal transmission speed; the relative direction between the slave equipment and themaster equipment is acquired according to an incoming wave direction of the feedback signal received by the ultrasonic receivers; and the relative depth between the master equipment and the slave equipment is calculated out according to the water pressure data in the feedback signal. In addition, the invention provides electronic equipment and the electronic equipment system applied to diving.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic device, system and control method applied to diving. Background technique [0002] Usually, two or more people are required to dive for safety reasons. Due to the barrier of sea water, divers cannot use reference objects to judge their own position underwater, nor can they judge the relative distance between diving partners. In the event of an accident (such as being unable to see your partner due to too far away or poor visibility in the sea, being washed away by the current, rising midway due to a breathing device failure, passively rising or sinking due to poor buoyancy control, encountering a shark, etc. Dangerous creatures, etc.), the partners cannot determine each other's position, provide warning or assistance. [0003] The usual way to maintain distance between partners is to attach a "diving line" between the partners. This method can only be applied...

AI Technical Summary

Problems solved by technology

Sign language is limited by the visibility of seawater, and the communication distance is often less than 1 meter. Divers can’t even see their hand gestures clearly when the environment is harsh. Tapping the gas cylinder can only be tapped at a very short distance. The above methods cannot reliably attract the attention of the other party; The signal rope also has the above-mentioned problems such as kinks, pulling and entanglement
