For rapidly recovering electric power line transmission damaged by natural disasters,it is necessary to fast establish relief command system for effective communication on the scene.Therefore,this paper analyzes business demand of field re-lief and characteristic of wide-area interconnection technology and proposes overall satellite communication mode.Meanwhile,it analyzes local communication mode for field relief command,digital trunking communication frame-work and mobile phone communication technology and proposes digital trunking communication scheme which is used for field local communication command.Aiming at factors affecting wireless digital trunking communication covering,it propo-ses an expansion scheme for covering range.By a combining scheme of wide-area satellite interconnection and portable wire-less digital trunking system,it displays a construction case of the actual system.By field testing,it proves that this scheme is of satisfactory effect.
