| description | The methods and devices for providing communication between unmanned aerial vehicle and ground control station are analyzed in this paper. In many cases this solution is not optimal. The maximum length of the USB cable limits the distance between the radio modem and the ground control station by five meters. In many cases, this solution is not optimal. The maximum length of the USB cable limits the distance between the radio modem and the ground control station by five meters. It creates discomfort to take out the radio modem on the mast. Bad fixing of the USB cable connector in the corresponding port of the laptop creates an unreliable connection, which often causes a non-qualified transmission of telemetric information. This method of connection allows only a point-to-point connection. At the same time, it is often necessary to simultaneously transmit a telemetry signal to several terrestrial devices. It is proposed to provide this type of communication using a wireless (Wi-Fi) network. The wireless network in this work was used to exchange telemetry signals between the RFD-900 radio modem and the ground station of the unmanned aerial vehicle (installed on the laptop) in full-duplex mode. The transmission of telemetry signals to the Wi-Fi transceiver, built into the laptop, is carried out using the ESP8266-12E module, which is included in the NodeMCU-debug board. The ESP8266-12E module is connected via the UART interface to the output of the radio modem and used as a ground system's wireless signal repeater. To implement such signal transmission in the Delphi 7 IDE was developed a software module based on the TCP/IP protocol. The developed device has the modularity and universality features, which expands the area of its application. For example: video signals wireless transmission (FPV), an applications not associated with remote-controlled aircraft. In addition, the developed device can be used as a wireless server for local Wi-Fi network building. It is planned to modernize the software in the future - it will be added algorithm for working with a file system, it will be developed the software for other operating systems (Linux, Android) etc. |
