Claim Text:
1. A bidirectional voice signal transmission system, comprising: a center console; a central router, being coupled to the center console for transmitting a broadcast voice signal and a control signal received from the center console by a base frequency; a plurality of node routers, wherein a bidirectional and serial wireless transmission path is constructed by the center console, the central router and the node routers, such that the center console is able to transmit the control signal to each of the node routers for carrying out the setting and management of the node routers through a download-link serial wireless transmission path of the bidirectional and serial wireless transmission path; therefore, a first node router of the node routers can receive the broadcast voice signal transmitted by the central router, so as to transmit the broadcast voice signal transmitted to a second node router of the node routers by a first frequency; moreover, the second node router transmitting the broadcast voice signal transmitted to a third node router of the node routers by a second frequency; and a plurality of mobile devices, locating in a signal-covering range of the node routers, and at least having a registering unit and a speaking unit; wherein when one of the plurality of mobile devices is adjacent to any one of the node routers, the mobile device outputs a register application to the a central console by activating the registering unit, so as to make the mobile device be permitted joining the bidirectional and serial wireless transmission path; moreover, the mobile device broadcasts a mobile device voice signal or transmits the mobile device voice signal to a specified mobile device through the bidirectional and serial wireless transmission path: wherein when the mobile device voice signal is transmitted to the central console, a RSSI (Received signal strength indication) signal, a sensing signal, the mobile device position, and the router position being transmitted out by the mobile device at the same time.
