Bernoulli equation verification experiment platform capable of being remotely controlled

Abstract

The invention discloses a Bernoulli equation verification experiment platform capable of being remotely controlled. The Bernoulli equation verification experiment system comprises a Bernoulli equationverification experiment device capable of being controlled by a computer, a service manager and a user terminal. The Bernoulli equation verification experiment device capable of being controlled by the computer is connected with the service manager through the Internet. And the service manager is connected with the user terminal through the Internet. According to the invention, related problems existing in a Bernoulli equation verification experiment set up in colleges and universities nowadays are solved to a certain extent, resources are reasonably utilized, related professional services for colleges and universities lacking the experiment conditions in China are provided, and the range of benefited people is expanded. For example, the unexpected 2020 new coronavirus event has great influence on the education industry, some theoretical course teachers can give lessons to students through a network platform, but experiments related to practical links cannot be achieved. The problem that an analogue simulation experiment lacks real experience can be solved, the teaching purpose is achieved by sharing a remote experiment, and the sharing education concept is achieved.

Description

technical field [0001] The invention relates to the technical fields of education, teaching and industrial control, in particular to a remotely controllable Bernoulli equation verification experiment platform. Background technique [0002] At present, water supply and drainage science and engineering majors in domestic colleges and universities generally need to set up relevant professional experiments, including Bernoulli equation verification experiments. At present, the experimental equipment generally includes self-circulating water supply, thyristor stepless speed regulator, manometer, piezometer, slide rule, constant pressure water tank, experimental pipeline, etc. During the operation of the hydraulic experiment, the experimental result data is obtained through the electromagnetic flowmeter and pressure transmitter installed on the equipment. [0003] At present, domestic Bernoulli equation verification experiment platforms can be classified into two types: one is fo...

Problems solved by technology

Since the actual operation must be carried out according to the experimental instruction, the influence of various factors must be excluded, and there are inevitably systematic errors in the experiment. In order to obtain accurate experimental results, it is necessary to conduct multiple experiments, but in actual operation, it is difficult to carry out Repeated experiments to obtain accurate experimental results; and in actual operation, before recording each data, it is necessary to manually observe the instrument value, and obtain valid data after it is stable

As a result of the above, colleges and universities that have purchased experimental equipment can only provide experimental opportunities for local students, and experimental resources are not fully utilized, and the experimental process of local students is inconvenient and difficult to obtain accurate experimental data. Relevant experiments cannot be carried out in the region, students lack practical operation opportunities, cannot master the ability of experimental operation, and cannot obtain practical and intuitive experimental data

[0004] The second is the remote experiment scheme based on the Internet, which mainly uses the software simulation experiment platform to carry out online simulation or virtual experiment. The experimental phenomena and data of this scheme are all calculated by software under ideal conditions, and the virtual experiment is completely virtualized by software. The environment does not have the authenticity of the experimental process. The experimental process is solidified and cannot simulate various interference factors and errors in the actual situation. Although the experiment is easy to understand the experimental process, the experimental effect is difficult to compare with the real experiment. and the cultivation of problem awareness
