Beschreibung
Zusammenfassung:	The invention discloses an automatic diagnosis method for remote control/ remote transferring instruction transmission fault of an industrial control system. The method comprises the steps of monitoring each IED, remote movement device and switch of a plant station, and a front communication device of a main station on real time; collecting communication messages of measurement objects meeting the conditions; extracting a remote control/ remote transferring instruction; if detecting the change on the remote control/ remote transferring instruction at the front communication device side of the main station, triggering the remote control/ remote transferring detection process; diagnosing the remote control/ remote transferring instruction and a remote control/ remote transferring response instruction for different node locations; generating remote control/ remote transferring failure early warning according to the diagnosis result. With the adoption of the method, the circumstance that the remote control/ remote transferring instruction is lost during the communication between an EMS system and an automation system of a transformer substation can be detected in the first time; in addition, the fault node can be automatically accurately positioned; therefore, the accuracy of measurement information transmission in the EMS system of a power grid can be ensured, and meanwhile, the burden on operators can be greatly reduced.
