the flight control computers. This sort of system can be used with mechanical or fully by the fly-by-wire controls. This type of system interprets the inputs from the pilot and then calculates the control surface positions needed to achieve a desired outcome. It can also control various aircraft components such as the rudder, aileron, and engine controls. Although the pilot is not aware of all the control outputs that are affecting the outcome, the aircraft is still reacting according to the expected. This type of system helps prevent the pilot from operating the aircraft outside of its safety envelope.
wire communication system for an unmanned aerial vehicle” consists of 3 parts: Fly by wire control system, Real-time sensor data visualization from the UAV, and the Communication between the UAV and the ground station. Aiming at the problems in the traditional Unmanned Aerial Vehicle (UAV) like the stability, accuracy, data acquisition, and display system. The fly-by-wire will take care of the accuracy and control stability of the UAV, through sensor data visualization post-processing of the data is done, and the communication is established between the UAV and ground station to control the UAV. All the sensor data can be visualized using wireless sensor networks through Blynk software. The communication between the ground station and onboard controller uses Telemetry. Thus, the proposed system which consists of fly-by-wire integrated with sensor data visualization makes the UAV less weight, more accurate & stable using the feedback loops. The final output can be implemented on any UAV.
A wireless sensor network is a type of network that collects data about the physical conditions of an environment. These sensors can monitor various environmental conditions such as air quality, noise, and temperature. Similar to wireless ad hoc networks, WSNs rely on the spontaneous formation of networks to collect data. These Wireless Sensor networks can monitor various environmental conditions like temperature, pressure, and sound. A wireless sensor network (WSN) is composed of nodes, each with its own set of components connected to other sensors. These nodes typically have an external antenna or a radio transceiver, as well as an electronic circuit that can be used to interface with the energy source and sensors. The cloud server used for the WSN is Blynk.
Key Words: Fly-by-wire, sensor data visualization, UAV data acquisition, ground station, Blynk, Telemetry.
1. INTRODUCTION In a traditional UAV with the wiring system there is a chance of failure of the UAV due to damage in wires and also the stability and accuracy of this type of UAV are comparatively less. Considering the problems in the traditional Unmanned Aerial Vehicle (UAV) like the stability, accuracy, data acquisition, and the display system, a new system has been created which contains three parts- the Fly by wire control system, Real-time sensor data visualization from UAV, and the communication between the UAV and the ground station. The fly-by-wire will take care of the accuracy and control stability of the UAV, through sensor data visualization post-processing of the data is done, and the communication is established between the UAV and ground station to control the UAV.
Blynk is the server which is designed for Internet of things. It can control hardware in wireless method and can display sensor data. It can also store data and can help to visualize in many ways. The main important thing is to access the UAV by establishing the communication channel between the onboard microcontroller and the ground station. The method used to establish the connection between the ground station and the onboard microcontroller is Telemetry. 915Mhz telemetry module pair is used to achieve the connection. Telemetry is a highly automated communication process by which the measurements are made and other data is collected at remote or inaccessible points and transmitted to receiving equipment for monitoring, display, and recording.
A fly-by-wire system is a type of aircraft system that is fully automated and eliminates the need for manual flight controls. It works by converting the movements of the flight controls to electronic signals, which are then sent to
