摘要： Method and apparatus for providing a filtered signal which indicates of a flow of fluid to a fluid pressure communication conduit, the flow being dependent upon the pressure of fluid in a chamber. The pressure in the chamber is controlled by one or more pressure adjusting valves. The invention provides for receiving into a data processing module one or more valve signals indicating open states of the pressure adjusting valve or valves, and also a flowrate signal from a flowrate sensor, which represents the real instantaneous flowrate, and it is this signal which needs to be filtered to remove transients. The invention provides for choosing between a first processing mode and a second processing mode for the flowrate signal. The first processing mode is used when the second processing mode is not in effect, and when neither of the valve signals indicates an open valve. The second processing mode is activated a valve signal indicates an open valve. The second processing mode, when activated, proceeds according to a predetermined procedure and then returns to the first processing mode after no valve signal indicates an open valve. The signal is processed by either the first processing mode or the second processing mode, depending on whether valve signals have been received, and provides the filtered signal as an output to equipment external to the data processing module.

摘要： The invention provides a real time process control system for control of machinery. The system has a master control module and a slave control module which receives control signals from the master control module. Both control modules send control signals to a control effector and cause changes in at least one effect causing quality of the control effector. The slave control module establishes a target value for the effect causing quality of the control effector based on the signal it receives from the master microprocessor. A sensor connected to the control effector and to the slave control module provides signals in the slave control module which indicate an actual value for the effect causing quality of the control effector. A feedback loop controls the control signal from the slave microprocessor to the control effector to adjust the value of its effect causing quality in accordance with the target value. In the event that the signal from the master control module to the slave control module is interrupted a discrepancy between actual and target values of the effect causing quality indicates interruption of the signal. The invention provides an increased deadband for the feedback loop to permit a discrepancy large enough to be detectable and useable as an indication of interruption of the signal from the master control module to the slave control module.
