Unmanned helicopter relay data link system and control method thereof

Abstract

The invention discloses an unmanned helicopter relay data link system. The unmanned helicopter relay data link system comprises a relay unmanned helicopter module, a base station module, a ground station module, a remote controller module, a wireless transmitting module, a wireless receiving module, a relay unmanned helicopter main controller module and a target unmanned helicopter main controller module. The invention also discloses a control method for controlling the unmanned helicopter relay data link system. The control method comprises the following steps: 1, outputting the parameters of a controller and transmitting the output parameters to the base station module via a UDP network protocol by the ground station module; 2, encapsulating acquired flight control data and task data into one data frame by the base station module; 3, extracting the flight data and the task data in a data part respectively; 4, comparing the destination address of the data frame with the local address of an unmanned helicopter; 5, acquiring sensor data; and 6, after the base station module receives downlink data packets, forwarding the received downlink data packets to the ground station module. The unmanned helicopter relay data link system has the advantages of low communication cost, high transmission efficiency, high generality and the like.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicle data communication, and especially designs an unmanned helicopter relay data link system and its control method. A wireless data transmission scheme beyond the line-of-sight range between the UAV and the ground station module. Background technique [0002] Unmanned helicopter is an aircraft based on wireless remote control system or automatic control system to complete autonomous flight. Compared with manned aircraft, unmanned helicopter has many advantages such as small size, low cost, light weight, convenient operation and control, and flexible flight. , and can adapt to the harsh environment that many manned aircraft cannot adapt to, and can replace manual tasks in high-risk and high-radiation areas. All walks of life have their applications involved. Therefore, in recent years, many mainstream countries have focused on research on unmanned aircraft. helicopter system. ...

Problems solved by technology

The former is not only due to the high cost of construction, but also the network coverage and network quality of telecom operators cannot be reliably guaranteed. It will be very inconvenient to use it in the UAV system. The use of satellites is not only costly, but also Since the current satellite communication may affect other functions of the satellite, if the relay communication technology based on short wave is only used, due to the complexity of the relay system, to achieve a longer flight distance, not only the cost is high, but also the multi-channel Inheritance will inevitably reduce the signal strength from the ground station module
