摘要： A Hard Real Time Control Center (HRTCC), comprised of hardware, software and firmware, with time synchronisation and time delay compensation methodologies that allows Application Hardware and/or User Input Devices to be networked together on any communications network as if there were negligible network delays in the system, is disclosed. This will allow Application Hardware and/or User Input Devices (connected to an HRTCC at one location (node) on the network) to control or operate Application Hardware and/or User Input Devices connected to another HRTCC at a remote location without the detrimental effects of network time delays. The time synchronisation of the various HRTCCs on the network can be enabled using hardware (e.g. a global positioning system (GPS)) or any other software method (e.g. Network Time Protocol). Using time stamps from the time synchronisation, the time delay of the signals (data) transferred over the network can be determined. The main embodiment of the time delay compensation methodology is an estimator/predictor algorithm. The estimator generates signal information that allows the predictor, using the time delay, to project the signal information characteristics into the future by an amount equal to the time delay. If this predicted signal is used rather than the delayed signal, there will be no readily apparent time delay in the system thereby significantly improving the stability and performance of the associated application. Any software architecture can be used such as servant-client, token ring or peer to peer.
