Description
Technical field
The present invention relates to a kind of devices for switching to automatically controlled power supply for the power electric automatic emergency of power buoy.This hair
It is bright to be also related to a kind of control method for switching to automatically controlled power supply for the power electric automatic emergency of power buoy.
Background technique
Power buoy is a kind of buoy for not needing anchoring and fixing, may be implemented autonomous and fixed point remaining.Power is floating
Mark possesses more huge and complicated electrical equipment compared with mooring formula buoy, and power consumption is more considerable, so power buoy
More stable power supply is needed to ensure the normal operation of electrical equipment.Mooring formula buoy, will not be with water flow stream due to being fixed
It is dynamic；And out of control power buoy can be flowed with water flow, and staff is caused to be difficult to find out of touch power buoy.Cause
This, needs to provide and design the relatively reliable energy and power supply plan for power buoy.
Currently, buoy is generally powered by the way of single power supply or increase backup power source.For example, application No. is
A kind of buoy uninterruptible power supply management circuit based on super capacitor is provided in the patent document of CN201420400354.0, is adopted
It is powered with solar battery, super capacitor mould group, dry cell triplicity to buoy circuit system.Though this electric power management circuit
The sustainable work of buoy, but its higher cost so may be implemented, later maintenance is complicated.According to this electric power management circuit,
It is possible to the case where solar battery can not work occur under continuous severe weather conditions, influences the normal operation of buoy, very
To in the case where electricity exhausts, loses and contacted with buoy.
Under normal circumstances, power buoy uses two class battery packs, main to master one is the lower automatically controlled battery pack of voltage
The voltages such as controller, control panel, compass, GPS, communication radio station, alarm lamp are lower and the lower light current power electrical apparatus of power；
Another is the higher power battery pack of voltage, and mainly the higher power-equipment of and power higher to voltages such as propellers supplies
Electricity.The capacity of automatically controlled battery pack and power battery pack is designed according to regulation task, under normal conditions can be in the defined time
It interior completion appointed task and is normally recycled.But be not excluded in some special cases, power buoy before being recovered, certain
A kind of electricity of battery pack is depleted prior to another battery pack.When power battery pack electricity is first depleted, and automatically controlled battery
When group can also continue to weak current equipment work, even if power buoy is unable to autonomous, and flowed with water flow；But as long as by electricity
Battery-powered master controller is controlled to guarantee the azimuth information of power buoy being real-time transmitted to remote worker by radio station,
Power buoy can be found and be recycled according to real-time azimuth information by staff.When automatically controlled battery electric quantity is first consumed
To the greatest extent, it and when power battery pack has electricity, cannot be worked by automatically controlled battery-powered master controller, even if power battery pack has
Electricity, main control also can not effectively control propeller work, the azimuth information of power buoy can not be passed through radio station real-time transmission
To remote worker, searching for staff, out of touch power buoy difficulty is increased or even power buoy is lost.
Therefore, it in the case of power buoy is using automatically controlled battery pack and power battery pack associating power supply, needs to design one kind
Power electric switchs to automatically controlled electricity power supply emergency switching device, to guarantee in the case where automatically controlled battery electric quantity exhausts, power automatically
Buoy can also continue to work normally a period of time and notify remote worker and flash alarm lamp, guarantee that staff to the greatest extent may be used
Power buoy can be recycled in time.

The 1st foot of relay K1 is disconnected from the 3rd foot onto the GND of the 2nd foot, and then the 1st foot of monolock storage is made (to latch enabled LE
End) it is low level, even if the 4th foot of monolock storage (end Q) does not change followed by the 3rd foot (end D), and original state is continued to, i.e.,
Always high level is exported, continues to ensure that relay K1 maintains working condition always.In this case, even if because of automatically controlled battery
8 stop power supply after voltage recovery generate virtual height voltage, once more partial pressure U1 > U0 of automatically controlled battery 8 and make voltage comparator the 4th
Foot exports low level signal to the 3rd foot of monolock storage (end D), and the 4th foot of monolock storage (end Q) does not also become followed by the 3rd foot (end D)
Change, remains that output high level is constant, power supply switching module 7 will not be made to again switch to automatically controlled 8 power supply state of battery.
