The invention relates to a dispatching data network and a distribution network data transmission network capable of independently collecting top layer interconnection. The dispatching data network and the distribution network data transmission network comprise a major network switch, a major network 2M line, a major network SDH device, major network SC-FC jumping fibers, a major network ODF device, an optical cable, a distribution network switch, a distribution network 2M line, a distribution network SDH device, distribution network SC-FC jumping fibers and a distribution network ODF device; the major network switch is connected with the major network SDH device through the major network 2M line, the major network SDH device is connected with the major network ODF device through the major network SC-FC jumping fibers, the major network ODF device is connected with the distribution network ODF device through the optical cable, the distribution network ODF device is connected with the distribution network SDH device through the distribution network SC-FC jumping fibers, and the distribution network SDH device is connected with the distribution network switch through the distribution network 2M line. By means of the dispatching data network and the distribution network data transmission network, a network topology model suitable for transmitting automated information of a main regulation station and an auxiliary regulation station is built. An SDH transmission network is adopted in a core router layer to conduct main and auxiliary network interconnection, longitudinal encryption equipment of main and auxiliary networks is adopted for achieving information safety protection, and data interaction of the main and auxiliary networks is achieved.
