Abstract

The invention discloses a power supply stable on-off control circuit and method used in a sea surface floating device. The circuit comprises a switching unit, the input end of the switching unit is connected with a power supply, the output end of the switching unit is connected with the input end of a voltage stabilizing conversion circuit, and the output end of the voltage stabilizing conversion circuit is connected with a microcontroller and other electricity utilization units of the device. The switching unit is composed of a gravity switch and an electronic switch which are connected in parallel. The microcontroller detects on-off of the gravity switch through a detection circuit and controls on-off of the electronic switch through a driving circuit. According to the control circuit and method, the device is electrified when being vertically arranged in a positive mode and is powered off when being vertically arranged in an inverted mode by exceeding a certain time, on-off of the device can be conveniently achieved, and in addition, the situation that an interface is additionally arranged and consequently, the sealing performance of a shell of the device is damaged is avoided.

Description

technical field

[0001] The invention relates to the field of ocean detection, in particular to a power supply stabilization on-off control circuit and control method used in sea surface floating equipment in this field. Background technique

[0002] With the development of economy and society, the ocean has become more and more important. To develop and utilize the ocean, we must first understand the ocean and conduct various detections on the ocean. Part of the detection equipment itself needs to work floating on the sea surface, such as various small monitoring buoys and indicating buoys; in addition, detection equipment deployed on the seabed or at different depths of sea water often needs to be reused when it floats to the sea surface. Devices such as connected beacons assist recovery. Whether it is a buoy or a beacon, its internal energy is mostly a battery.

[0003] Due to the ups and downs of the sea surface, the above-mentioned sea surface floating equipment inevit...
