Title:
TERMINAL PRESSURE CONTROL DEVICE AND TERMINAL PRESSURE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2018/092866
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a terminal pressure control device and a terminal pressure control method with which power consumed by an air compressor can be reduced while suppressing fluctuations in the supply pressure to a terminal appliance, by tracking changes over time in a pipeline network, with which a desired pressure can be supplied to the terminal appliance, and with which energy savings can be achieved. In order to achieve this objective, a terminal pressure control device of a pneumatic system which supplies compressed air from an air compressor to a terminal appliance via a pipeline layout is configured in such a way that the pipeline layout, a measured value of a terminal pressure at the terminal appliance, and a measured value of a pressure difference of at least one pressure loss element in the pneumatic system are input into the terminal pressure control device, and the terminal pressure control device calculates a control parameter for controlling the terminal pressure, on the basis of the pipeline layout, the measured value of the terminal pressure, and the measured value of the pressure difference, and outputs a pressure command value for the air compressor using the control parameter.
