PURPOSE:To improve the circuit use efficiency of a remote maintenance center, and to smoothly execute an operation of maintenance support by providing a shared patch data store area in an integrated monitoring device. CONSTITUTION:An integrated monitoring device 16 is provided with a shared patch data store area 14 for storing patch data, and also, by sending the patch data from a remote maintenance center, its patch data is transferred to the device 16 from the remote maintenance center, in the case of commanding a specific maintenance work to each of electronic computers 11-13. Also, it is accumulated once in the shared patch data store area 14, and thereafter, the patch data is transferred to each of computers 11-13 from the patch data store area 14. In such a way, it becomes unnecessary to perform repeatedly remote patch between the remote maintenance center and each of electronic computers.
