The invention discloses an RC
remote control system upgrade device, a
remote control model control system and a control method.The RC
remote control system upgrade device comprises a box body, a
power module, a main control module, a 4G / 5G remote control module and a 2.4 G
radio frequency module are integrated in the box body, the 4G / 5G remote control module is used for receiving control signals transmitted through a 4G or 5
G network, and the 2.4 G
radio frequency module is used for receiving the control signals transmitted through the 2.4 G or 5
G network. The 4G / 5G control module is used for receiving a 4G / 5G
control signal and transmitting the received
signal to the main control module, the main control module is used for
processing and converting the received 4G / 5G
control signal into a 2.4 G
control signal and transmitting the 2.4 G control
signal to the 2.4 G
radio frequency module, and the 2.4 G radio frequency module is used for sending the received 2.4 G control
signal to a bound remote control model; a
camera module is arranged outside the box body, is in communication connection with the main control module and is electrically connected with the power supply module; on the basis that an original 2.4 G remote
control system of the remote control model is not changed, 4G and 5
G network technologies are combined with a 2.4 G remote
control system of a traditional remote control model, and remote control and video real-time return functions of the remote control model are achieved.
