The invention relates to an electric power scheduling technology, and particularly relates to a power grid regulation and control integrated system based on a DMIS. Problems that existing electric power scheduling systems are difficult to acquire huge amounts of data information comprehensively and in real time are solved by the power grid regulation and control integrated system based on the DMIS. The power grid regulation and control integrated system based on the DMIS comprises pick-up heads, a hard disk video recorder, a matrix switching device, a server, client terminals, a monitor, a synchronization switch, a first bus and a second bus. The signal output ends of all the pick-up heads are connected with the first bus. The signal input end of the hard disk video recorder is connected with the first bus. The signal output end of the hard disk video recorder is connected with the second bus. The signal input end of the matrix switching device is connected with the first bus. The signal input end of the server is connected with the second bus. The signal input ends of all the client terminals are connected with the second bus. The signal input end of the monitor is connected with the signal output end of the matrix switching device. The power grid regulation and control integrated system based on the DMIS is suitable for electric power scheduling.
