Solve UAV Manufacturer Design Challenges with TI's New Reference Design
At present, drones have clearly become the main force in large-scale electronic exhibitions such as the International Consumer Electronics Show (CES). According to statistics, on the stage of CES, there are more than 60 drone exhibitors participating in the exhibition, showing the unique charm of drone technology to the world.
From parcel shipping, aerial photography, to security, monitoring, monitoring and communications, drones are used in a variety of applications. However, two key challenges facing drone developers – battery life and flight time – still exist. To help the aircraft avoid obstacles, drone manufacturers add direction and sensing to their products, but the added weight may have a negative impact on the short battery life.
Texas Instruments is working to address the technical challenges faced by drone developers through new reference designs that help extend the flight of quadcopters and other non-military consumer and industrial drones. Time and battery life to help them better deliver shipping packages, monitoring and communication services, or for long-distance assistance.
Stelios Kotakis, senior analyst for data transmission and management services at IHS Markit, said, "Flight time is still a top design challenge for recreational quadcopters and professional drones, especially those used by companies for super line-of-sight operations. The courier company wants drones to have longer battery life and is also testing how far it can take to transport packages using drones.†IHS Markit's latest research* data shows that in ideal flight conditions and without additional payload In this case, nearly 50% of the drones on the market have a battery life of less than 30 minutes, 35% of the flight time is between 31 and 60 minutes, and the remaining 15% can fly for more than one hour.
Two new drone reference designs from TI may help you understand how to solve drone design challenges and improve flight time and battery life issues:
· Breakthrough battery management for drones: The 2S1P Battery Management System (BMS) reference design converts drone battery packs into intelligent diagnostic black box recorders. This intelligent diagnostic black box recorder accurately monitors the remaining charge and protects the lithium-ion battery throughout the life of the battery. Designers can add measurement, protection, balancing, and charging capabilities to any existing drone design with the drone BMS reference design and extend flight time. The design also features a battery charge controller and an efficient DC/DC converter for efficient energy conversion. In addition, it can use the fuel gauge to accurately measure the remaining capacity over the life of the battery.
High-speed motor performance for propeller efficiency: The sensorless high-speed field-oriented control reference design for UAV electronic speed control helps the electronic speed controller achieve a leap in efficiency, making it faster than 12,000 rpm ("1.2kHz And also has a fast reversal function for achieving a more stable roll motion. This means longer flight times and smoother and more stable performance.
