Tide simulation monitoring system and monitoring method thereof

Abstract

The invention discloses a tide simulation monitoring system and a monitoring method thereof. The monitoring system comprises an industrial control computer, a tide electric control cabinet, an electric valve, a water pump alternating current variable frequency motor, a water level meter and an L-shaped communicating pipe, wherein an ADMA conversion module and an alternating current frequency converter are contained in the tide electric control cabinet; a tide instruction is inputted by a man-machine operation part of the industrial control computer; the instruction is sent according to a RS485 communication method; the instruction is converted into a simulating signal by the ADMA conversion module and then is sent to the electric valve; the electric valve is controlled to change according to a preset opening size and time, thereby realizing the change in tide level; the L-shaped communicating pipe is connected with the bottom of a side wall of a water pool; the water level meter is used for measuring the practical change in water level in the L-shaped communicating pipe and feeding a practical data to the industrial control computer; and the practical data is displayed in a curve form. The tide simulation monitoring system has the advantages of high degree of automation, simple structure, convenience in control operation, high precision of monitored data, excellent man-machine interaction, and wide application to tide simulation tests of ocean engineering pools and port industrial pools.

Description

technical field [0001] The invention belongs to the field of ocean engineering test equipment, and relates to ocean engineering and harbor engineering pool tide simulation equipment, in particular to a measurement and control system capable of simulating tide changes and a measurement and control method thereof. Background technique [0002] Tasks such as water conservancy scientific research and coastal engineering research require that the original tidal phenomenon be reproduced in the physical model, that is, the riverbed shape of the natural estuary section is made into a scale model, and the natural tidal phenomenon is required to be reproduced by scaling down the water volume and time, that is, Tidal simulation. An accurate tide simulation process requires a complete set of tide simulation measurement and control devices. At present, the common tidal simulation methods at home and abroad include pressure type tide tank, variable overflow tailgate type, multi-channel m...

AI Technical Summary

Problems solved by technology

The pressure type tidal tank has huge equipment, complex supporting equipment, high operating costs, and high operating noise; the variable overflow tailgate has many control parameters, and the electromechanical transmission structure of the wide-mouthed door body is complicated, and the water supply is constant and consumes energy; multi-channel The mode adopts many actuators such as pumps and solenoid valves to be placed in each channel. Among them, the pumps and solenoid valves only have two working states of open and closed, so it is a step-type flow adjustment with multiple open or closed flow controls in one channel. The rising tide mode, so it has the defects of complicated control and operation and low precision
