AI Technical Summary

Problems solved by technology

[0003] The traditional water supply network hydraulic model system is mainly based on C / S terminal (client) software, and specific model software (such as Epanet, WaterGEMS, etc.) and even related databases (Mysql, SQLsever, Oracle, etc.) need to be installed. The installation process is complicated. The operation is complicated and difficult, and the need for model viewing and simulation calculation cannot be realized anytime and anywhere

At the same time, the model calculation and solution efficiency of traditional modeling software is severely limited by the performance of personal computers

[0004] Traditional water supply network model software lacks unified management records for parameter adjustment and modification. Users need to repeatedly perform a large number of trial and error parameter adjustments during the long-term water supply model construction and simulation application process, and it is inevitable that the adjusted parameters will be forgotten. , requires repeated verification and confirmation by the user, and the operation of parameter restoration, modification and adjustment is inconvenient, which affects work efficiency

[0005] The hydraulic model of the water supply network contains a large amount of actual data of the pipe network, and the data confidentiality management requirements are high, while the traditional hydraulic model system of the water supply network mainly uses independent files as the carrier, and the management of the model scheme is relatively scattered, mainly relying on the system personnel management to avoid Model data leakage, data security is difficult to be guaranteed

At the same time, the file form is used as the carrier of the hydraulic model of the water supply network, and each person independently performs modeling work with their own version of the model, which cannot realize multi-person collaborative modeling and reduces modeling efficiency.

[0006] In the model verification process of the traditional water supply network hydraulic model system, it mainly relies on the experience of professional modelers to manually adjust the model parameters to achieve the target accuracy requirements. This is a process of continuous trial and error, which is inefficient. The verification process of medium and large models takes 1 to 3 months

Moreover, the traditional model verification method has a certain subjective judgment of the modeler, which may lead to a large deviation between the results of the model and the actual situation under the simulation conditions of other working conditions, and the versatility is poor.
