All lower-level observation stations serve as service ends, an upper-level dispatching center or a data center serves as a client end, a center side initiatively initiates a connection request, a communication link between the center side and a base-level station is established, and through a defined application layer data transmission protocol, it is ensured that ports of the center side are not exposed in a network any more; and the initiative of the connection with the user, the connection duration and the connection mode is mastered, a server on the center side is avoided, the situation that the ...
