Remote Control System
Remote Control System
The remote control system newly developed by Numbo can assist the excavator to realize remote control outdoor operation, with the maximum transmission distance of 30 km. It can reduce the difficulty of operation, protect the personal safety of operators to the greatest extent, provide convenience for high temperature, high heat and high dangerous working conditions. It can also solve the problems of driver safety, commuting cost, recruitment difficulties and management difficulties in the mining process, further improve the efficiency of ore mining and reduce production costs through automatic and intelligent means.

Performance & Functional Features:
➤Code rate: 10M; Receiving sensitivity: -97dBm; Transmission distance: 30KM;
➤Support 720P@30fps/1080P@30fps /1080P@60fps HD video transmission;
➤Support working frequency customization;
➤Support standard TCP/IP protocol, can be accessed as network equipment;
➤Support local and remote firmware upgrade;
➤Adopt Single carrier frequency domain equalization (SCFDE): In complex environment, multipath fading and interference are very strong, which seriously affect distance and reliability of communication. The technology introduces efficient Fourier Transform Algorithm, which greatly reduces the computational complexity and the structural complexity of equalizer, and greatly improves performance of the system;
➤Adopt low density parity check coding algorithm （LDPC）, system sensitivity is improved by 3~6 dB;
➤Adopt H.265 encoding and decoding technology: It is a new video coding standard developed by ITU-T VCEG after H.264. In the implementation process of this project, it will be implemented by pure hardware based on FPGA, reducing the existing transmission delay from 500ms to 150ms.
