Spread spectrum communication system of high-voltage AC carrier for electronic detonator network

In order to set up the large-scale network of electronic detonators, high-voltage AC carrier spread spectrum communication mode is proposed in this paper. Based on this technology, the network size of electronic detonators could be enlarged. The spread spectrum communication brings many advantages, such as high-speed transmission of information, anti-jamming and so on. Adopting high working voltage could enhance the ability of anti-jamming and enlarge the size of detonation network. Based on this mode, transmission channel of the mode was analyzed. Besides, the spread spectrum communication system was designed and simulated. The complete system was simulated and the results verify the feasibility of the proposed mode.
