Onboard controlling system design of unmanned airship

Unmanned airship possesses some advantages, such as long time hovering, much less energy consumed and cost efficiency. It is becoming one of the focus interests in the field of unmanned vehicles. An onboard controlling system was designed in this paper, in which microcontroller and corresponding peripherals are included. With STC12C5A60S2 as the central unit, the onboard microcontroller was designed in detail including MCU, ultrasonic sensor, compass, battery monitor circuit, alarming signal generation and so on. At last, the flowchart of the software is presented. From the experiment result, the onboard controlling system could satisfy system requirement and possesses such advantages as fast response, lower weight and lower energy consumed.
