Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0017] like figure 1 As shown, an unmanned aerial vehicle redundant power supply device of the present invention is composed of a power supply module 1, a power management module 2 and a digital servo voltage module 3 connected in sequence.
[0018] like figure 2 as shown,
[0019] (1) Power supply module 1 uses dual lithium battery output, the main power supply uses 11.1V 3SLIPO, and the backup power supply uses 11.1V 3SLIPO or 7.4V 2SLIPO, which is used for GPS, autopilot, data transmission, image transmission, digital steering gear and other equipment Provide a voltage source;
[0020] (2) The function of the power management module 2 is to manage and control the two voltage sources, and the two voltage sources are mutually backed up to meet the redundancy design. It includes a LTC4416 integrated power management chip, 3 resistors, and 3 P-channel MOS...

The invention discloses an unmanned aerial vehicle redundant power supply device. The unmanned aerial vehicle redundant power supply device comprises a power module with dual branches of lithium battery inputs and for supplying power for a GPS, an automatic pilot and a data transmission and image transmission apparatus, a power management module connected with the power module and used for controlling voltage input sources so that the two input sources can be backups of each other, regulating a resistance proportion value to use a standby power source for undervoltage protection of a main power source, and recovering the switching function of the main power source to meet redundant design, and a digital steering engine voltage module connected with the output of the power management module and used for realizing voltage-stable filter output of the power source by use of a DC-DC integrated synchronous step-down controller and providing a digital steering engine with a working voltage. The device is simple in structure; two battery packs are taken as the input voltage sources; the redundant design and different equipment power supply requirements are met by use of a related integrated power management chip and the DC-DC integrated synchronous step-down controller; as a result, high stability and reliability are achieved.
Description
technical field [0001] The invention relates to the field of power supplies for unmanned aerial vehicles, in particular to a redundant power supply device for unmanned aerial vehicles. Background technique [0002] The full name of "UAV" is unmanned aircraft (English abbreviation: Unmanned Aerial Vehicle), which is an unmanned aircraft mainly controlled by radio remote control or by its own program. There is no cockpit on board, but equipment such as autopilot and program control device are installed. The personnel on the ground, on the ship, or at the remote control station of the parent aircraft track, locate, remotely control, telemeter and digitally transmit it through radar and other equipment. [0003] With the development of the times and the advancement of science and technology, modern drones have strict requirements for power supply systems. Electronic equipment such as data transmission, image transmission, autopilot, and program control devices need stable and r...
