Through the device in this embodiment, a control circuit capable of controlling external power supply of the low-voltage battery is provided, so that under the condition that power can be supplied under water, the AUV (i.e., underwater equipment) leaves the arrangement device, and various peripheral devices (i.e., power utilization devices) in the AUV are powered by the power battery in the AUV before the power is supplied.
As an alternative embodiment, the underwater power-on device as described above further includes: a connector 13, a first single pole, multi-throw switch, a second single pole, multi-throw switch, and an externally activated power interface, wherein the connector 13 comprises at least 6 cores; the power supply device comprises two first switch modules 31 and two power batteries, wherein the first switch modules 31 are in one-to-one correspondence with the power batteries;
for each first switch module, 2 first switch output ends of the first switch module 31 are connected with 2 first enabling pins of the power battery in a one-to-one correspondence manner, and at least one first switch output end of the 2 first switch output ends is connected with the corresponding first enabling pin through a first single-pole multi-throw switch;
the 2 second switch output ends of the second switch module 32 are connected with the 2 second enabling pins of the low-voltage battery 4 in a one-to-one correspondence manner, and at least one second switch output end of the 2 second switch output ends is connected with the corresponding second enabling pin through a second single-pole multi-throw switch.
The 6 pins in the connector socket of the connector 13 are connected with the 6 switch output terminals in a one-to-one correspondence, wherein the 6 switch output terminals include: 4 switch outputs in the two first switch modules 31 (i.e., the first switch module 31-1 and the first switch module 32-2) and 2 switch outputs in the second switch module 32;
when the first connector plug of the connector 13 is connected with the connector socket, any one of the switch output ends is broken, wherein the switch module is any one of two first switch modules 31 and second switch modules 32;
the external activation power supply interface is used for being connected with a power supply source with preset voltage, the external activation power supply interface provides an activation power supply for the power utilization device, the external activation power supply interface also provides the preset voltage for the second switch module, so that the second switch module is conducted, and the preset voltage is higher than the voltage provided by the battery for the power utilization device.
The connector 13 comprises at least 6 cores, that is to say the connector 13 is at least a 6-core connector.
As shown in fig. 1, taking the first switch module 31-1 as an example, the first switch output ends 3 and 4 of the first switch module 31-1 are respectively connected with 2 first enable pins of the power battery in a one-to-one correspondence manner.
The first enabling pins are enabling pins on the power batteries, and each power battery comprises 2 first enabling pins, so that each first switch output end is connected with one first enabling pin respectively.
At least one first switch output end of the 2 first switch output ends is connected with the corresponding first enabling pin through a first single-pole multi-throw switch, and the first switch output end 4 is connected with the corresponding first enabling pin through a first single-pole multi-throw switch K2.
In the case where the connector 13 is a 6-core connector, the connector receptacle is a 6-core connector receptacle, and the first connector plug and the second connector plug are both 6-core connector plugs.
In the case of two first switch modules 31; pins 1, 2,3, 4,5, 6 in the connector socket are fixedly connected with switch output ends 1, 2 in the second switch module 32, switch output ends 3, 4 in the first switch module 31-1, and switch output ends 5, 6 in the first switch module 31-2 in one-to-one correspondence.
When the first connector plug of the connector 13 is connected to the connector socket, any one of the switch outputs is disconnected, i.e. the first connector plug is non-conductive.
In the case that the first connector plug is a 6-core connector plug, the 6 pins of the first connector plug are all open-circuit processing, i.e. the output ends of the switches are also open-circuit processing. When the AUV is deployed underwater, the connector needs to be plugged into the 6-core socket of the AUV. The AUV is powered down before it is powered down by closing the single pole multi-throw switch (i.e., the first single pole multi-throw switch and the second single pole multi-throw switch) in advance. Since the second connector plug is not turned on, only the external preset voltage activates to supply power at this time, and at this time, although the second switch module 32 is also turned on under the drive of the preset voltage, the 2 second enable pins of the low-voltage battery 4 are turned on, the preset voltage is higher than the voltage provided by the low-voltage battery 4 to the power utilization device, so that the AUV is supplied with power by the external activated power supply interface at this time. The external device (i.e., the power device 12) in the AUV is powered up after the power supply for the external active power interface is disconnected from the battery power supply. After the AUV finishes the task and is recycled to the deck or the wharf, the power-off of the AUV is realized by switching off the single-pole multi-throw switch.
Through the device in this embodiment, can be when the underwater equipment is put under water, power supply is carried out for the power consumption device through battery and high voltage battery.
As an alternative embodiment, the connector further comprises: a second connector plug;
when the second connector plug of the connector 13 is connected with the connector socket, two switch output ends in the same switch module are mutually short-circuited.
Under the condition that the second connector plug is a 6-core connector plug, the pins 1, 2,3 and 4 in the second connector plug are respectively in short circuit with each other in pairs, and the pins 5 and 6 are respectively in short circuit with each other. When the AUV is laid on the deck or dock, the connector needs to be plugged into the 6-core socket of the AUV to avoid the control of the low-voltage battery and the high-voltage battery by the first switch module 31 and the second switch module 32. If the AUV needs to be powered on, the single-pole multi-throw switch (i.e., the first single-pole multi-throw switch and the second single-pole multi-throw switch) on the AUV can be closed, so that two enable pins of each battery are mutually conducted, and further the battery 4 and the power battery on the AUV can be controlled to be powered on simultaneously. Because the power battery outputs a high voltage after passing through the DC-DC module, the power battery is now primarily powering all peripherals in the AUV.
By means of the device in the embodiment, the power supply of all the power utilization devices in the underwater equipment can be realized through the power battery without controlling the low-voltage battery and the power battery by the first switch module 31 and the second switch module 32.

The device is used for detecting the position of the AUV in the transmitting device, and when the distance is detected to be a certain value, the AUV can be judged to be still in the transmitting device, and the power battery in the AUV does not need to be electrified. An AUV is considered to have left the transmitting device when the detected distance is greater than a certain value or infinite.
2. Control panel
When the distance between the control board and the laser ranging module is larger than a certain value or infinite, the control board controls the first switch module 31-1, and two optocouplers at the first switch module 31-2 are closed. The power battery in the AUV is electrified, and the AUV can normally execute tasks.
Power-on mode switching unit
1.6 core connector socket (i.e., connector socket when connector 13 is a 6 core connector)
The output ends of the three optocouplers connected to the first switch module 31-1, the first switch module 31-2 and the second switch module 32 in the AUV internal circuit are used for switching the power-on modes of the AUV under different distribution scenes.
2. First 6-core connector plug (i.e., first connector plug)
As shown in the above figures, when the AUV is deployed underwater, the first 6-core connector plug needs to be plugged into the 6-core socket of the AUV. The AUV is started to close the single-pole multi-throw switch in advance before being drained. Since the 6-core connector plug is not turned on, only the external 27V (i.e., the power supply is activated through the external activation power supply interface) is activated at this time, the low-voltage battery 4 is activated at this time, and since the power supply voltage is higher than the voltage converted by the low-voltage battery 4 (i.e., the voltage supplied from the low-voltage battery to the power consumption device), the AUV is supplied by the external power supply at this time. The low-voltage battery 4 is used to power peripherals in the AUV (i.e., the power device 12) after the power supply is disconnected and before the internal power battery of the AUV is powered up. After the AUV finishes the task and is recycled to the deck or the wharf, the power-off of the AUV is realized by switching off the single-pole multi-throw switch.
3. Second 6-core connector plug (i.e. second connector plug when connector 13 is a 6-core connector, pins 1, 2,3, 4,5, 6 are shorted two by two respectively)
This second 6-core connector plug is required to be plugged into the 6-core socket of the AUV when the AUV is deployed on the deck or dock. When the AUV is electrified, the single-pole multi-throw switch on the AUV is closed. At this time, the battery 4, the power battery I5 and the power battery II6 on the AUV are powered on simultaneously. Because the power battery outputs a high voltage after passing through the DC-DC module, the power battery now primarily powers all of the powered devices 12 in the AUV.
3. Single pole multiple throw switch (i.e., first single pole multiple throw switch (K2, K3), second single pole multiple throw switch (K1))
Whether deck deployment, dock deployment or underwater deployment. The AUV needs to be powered on in advance to close the single-pole multi-throw switch.
A power supply unit:
1. low-voltage battery 4
Mainly under the condition of underwater power-up, the AUV leaves the distribution device, and various peripheral devices in the AUV are powered before the power battery in the AUV is powered up.
2. Power battery I5
The equipment is placed and completed, and power is supplied to a sensor and a counter-rotating motor in the AUV when the task starts to be executed.
3. Power battery II6
The equipment is placed and completed, and power is supplied to a sensor and a counter-rotating motor in the AUV when the task starts to be executed.
4. The low-voltage battery changes to a 24V DC-DC module (i.e., a low-voltage DC-DC module 8)
The voltage of the battery is stabilized to 24V, and the battery is connected with an external activated 27V, a high voltage is converted into a low voltage 25.2V, and then the battery is connected in parallel through a diode to supply power to the AUV.
5. High-to-low 25.2V DC-DC module (i.e., high-voltage DC-DC module 9)
The high voltage power Chi Wen is compressed to 25.2V, and is connected with an external activated 27V and a low voltage power 24V in parallel through a diode to supply power to the outside of the AUV.
Setting an AUV upper current path on a deck and a wharf: when the deck or the wharf is laid, the AUV is electrified to close the single-pole multi-throw switch, and the battery 4, the power battery I5 and the power battery II6 are simultaneously enabled to supply power for the equipment. When the AUV finishes the task, the AUV can be powered off by switching off the single-pole multi-throw switch.
Setting an AUV upper current process under water: the deck or the wharf is connected with a common watertight head (i.e. a first connector plug) through the 6-core connector, the power-on switch underwater laying device is closed in advance to provide 27V for the AUV, the system (i.e. the power-on device) can be maintained to operate after the low-voltage battery 4 is activated, and the AUV transmits a self-detection result to the internal control box of the laying device through an optical fiber. The self-checking result is normal, and the AUV has underwater laying conditions.
