Unmanned airplane avionics system based on intelligent mobile phone

The invention provides an unmanned airplane avionics system based on an intelligent mobile phone. A user operates a ground station through external equipment, an operation command is forwarded to the airplane-mounted mobile phone by the ground station through a network server, and a signal is sent to a single-chip computer by the airplane-mounted intelligent mobile phone; after receiving the command, the single-chip computer sends the signal to a steering engine of an assigned channel or an electronic speed controller so as to change the power and the flying gesture of an airplane, and meanwhile data are forwarded to the ground station by the intelligent mobile phone through the network server so as to ensure that the user can monitor the real-time state of the airplane through the ground station. The unmanned airplane avionics system based on the intelligent mobile phone achieves the purposes that remote control and monitoring can be conducted on the unmanned airplane by the user and can be normally used in regions with commercial wireless communication signal coverage, mobile phone software can be updated through plugin downloading or SDK development and the like to extend functions, and the unmanned airplane avionics system based on the intelligent mobile phone simplifies preflight installment and debugging processes and greatly reduces equipment purchasing cost.
