Description

technical field [0001] The invention relates to the technical fields of education, teaching and industrial control, in particular to a remotely shared water surface curve demonstration 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 water surface curve demonstration experiments. At this stage, the experimental equipment generally includes self-circulating water supply, thyristor stepless governor, variable slope bottom tank, ram, bottom slope level bubble, variable slope bearing, length scale, ram lock wheel, vertical slide rule, Lifting pole with ruler, lifting mechanism, etc. During the operation of the hydraulic experiment, the experimental data is obtained through the lifting rod with scale, the vertical slide rule, and the electromagnetic flowmeter installed on the equipment, and then the lif...

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 value of the ruler and instrument, 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
