Abstract

The invention discloses a distributed control system for river work physical model trend simulation. The system comprises a monitoring device, an automatic control module of tide boundary sea level, an automatic control module of runoff boundary flow and an automatic control module of reversing current boundary flow. The system can meet the similar requirement of a tidal model test on tide simulation. After being used, the system has the excellent effect and promotional value. The invention also provides a control method of the system, adopts an electrical control device, and automatically controls multi boundaries of a river work model under the control of a computer.

Description

Technical field: [0001] The invention relates to the field of tidal current simulation and automatic monitoring, in particular to a large-scale tidal river engineering model tidal current distributed simulation control system and control method. Background technique: [0002] The boundary of the tidal river engineering model usually has runoff, tide and reciprocating flow, and is tracked and controlled by a combination of actuators such as tailgates, butterfly valves, water pumps and feedback devices composed of detection instruments. The control methods of power flow simulation can be divided into two types: centralized control and distributed control. [0003] The traditional power flow simulation centralized control method is to insert various signal processing and drive interface boards into the expansion slot of the PC, and connect the interface boards with parallel signal lines of various instruments and devices to form a centralized measurement and control system. Th...
