A control system for adding and discharging water to a laboratory sink and its application

Abstract

The invention discloses a control system for adding and discharging water to a laboratory water tank, which comprises a water pressure measuring instrument, a single-chip microcomputer control system, a water filling switch and a water discharge switch, and the single-chip microcomputer control system is respectively connected with the water pressure measuring instrument, the water filling switch and the water discharging switch; At the same time, the data obtained by the water pressure measuring instrument is fed back to the single-chip control system, and the single-chip control system controls the water supply switch and the water discharge switch to add water or discharge water to the water tank through calculation. The control system for adding water and releasing water to laboratory water tanks of the present invention has simple structure and low cost, and can be applied to test water tanks of various colleges and universities. The method of calculating the average value of multiple measurements can meet the test requirements, and the accuracy of the water level is also greatly improved compared with naked eye observation.

Description

technical field [0001] The invention relates to the field of test instruments, in particular to a control system for adding and discharging water to a laboratory water tank and its application. Background technique [0002] In many colleges and universities with marine and related majors, there are water tanks for wave cross-section tests. The water tanks use wave generators to simulate the interaction between waves and buildings. [0003] Usually, the test conditions have various water levels such as extremely high water level, design high water level, design low water level, and extremely low water level. There are different switches for adding water and discharging water in the laboratory. Generally, there is a certain distance from the water tank, and the water level during adding and discharging water. Fluctuations are difficult to determine, and the water level accuracy requirements are high in the test, which often requires multiple adjustments to meet the requirement...

Problems solved by technology

[0003] Usually, the test conditions have various water levels such as extremely high water level, design high water level, design low water level, and extremely low water level. There are different switches for adding water and discharging water in the laboratory. Generally, there is a certain distance from the water tank, and the water level during adding and discharging water. The fluctuation is difficult to determine, and the accuracy of the water level is high in the test, which often requires multiple adjustments to meet the requirements, which is very cumbersome

The design and application of this aspect are rarely reported so far.
