Description
Technical field
The present invention relates to a kind of power supply devices, more particularly, refer to a kind of balloon borne power conversion of novel captive balloon
Device.
Background technique
Captive balloon system is divided into ground and aerial two parts, as shown in Figure 1.Captive balloon is a kind of itself do not drive
Power, by the lighter-than-air flight device that buoyancy goes up to the air, it is by tether cable delay scheduled position in the sky, as aerial platform,
It can be suitble to carry the electronic equipments such as various communications, detection, there is airborne period is long, load is big, deployment is convenient, expense is low etc.
Advantage is widely used in early warning detection in recent years, communication relay, prevents and reduces natural disasters, public safety etc..
Captive balloon aerial platform system is powered for a long time, and (as shown in Figure 1A) is main to take ground power transmission mode to realize, i.e.,
Two kilovolts or so of high pressure is risen to by ground power supply, high pressure delivers power to captive balloon aerial platform by pressure regulation heaving pile, so
After be depressured for aerial platform and payload (i.e. power unit) use.
Captive balloon is divided into ground anchoring, lets four working conditions such as lift-off, recycling decline and high-altitude stop fly away, wherein
High-altitude stops and ground anchoring state holding time is most, i.e., captive balloon, which has, is just in high-altitude resting state when task, do not have
When task or bad weather, for example ground anchoring state is just in when strong wind.It is inquired according to available data, captive balloon anchors at present
The ground Shi Caiyong high voltage supply mode, power supply are transmitted by longer cablet, and captive balloon release altitude is determined according to cablet height
Fixed, general captive balloon is from several hundred rice to several kms etc., and general medium-sized mooring ball is in several kms, the ground high voltage supply side
Formula to be lost on cablet especially greatly, simultaneously because cablet not only transmits electric power, it further include optical cable, it is electric as far as possible in ground anchoring
Power does not walk high pressure heaving pile when transmitting as far as possible, influences the cablet service life；Again with the presence of two kilovolts or so high pressures in electrion rainy days
Etc. security risks, therefore which be easy to cause power converter to lose and influence the heaving pile service life and increases security risk etc..
Captive balloon is switched to emergency lithium battery power supply when there is power supply trouble simultaneously, and current existing switching method has
Time interval has power down time, and is easy to lose data and failure when many load power down, is badly in need of uninterrupted power supply.It is existing
There is uninterrupted power supply generally to use following two mode, one kind is that relay adds end bulky capacitor mode, and which is simple and easy,
But when having the disadvantage in that load voltage ripple is big in actual operation, when backup battery voltage is lower, between master backup power supply
Switching easily cause power down failure；When connecting power supply, capacitor is easy quick charge, it is easy to the circuit before damaging capacitor,
There are security risks.Second is the switching realized before main power source and emergency cell using diode, is had simple and reliable
Feature, but also have following risk: when power unit power is larger, biggish electric current is flowed through on diode can make to produce on diode
Raw biggish pressure drop, then have and generate the waste that a large amount of power consumption causes the energy on the diode.
Summary of the invention
Insufficient for the demand and the prior art, the present invention provides a kind of balloon borne power conversions of novel captive balloon
Device, which can power to power unit and emergency lithium battery charging, can be realized high voltage supply and low pressure
Power supply is automatically switched, and allows mooring ball at high-altitude using high voltage supply, and when anchoring automatically switches to a low-voltage power supply mode,
And uninterrupted power supply when can be realized switching.To be solved by this invention is how while high-low pressure powers automatic switchover
