The mandatory treaty module is used for recording the mandatory treaty contents of the water conservancy industry such as hydrology, survey, design, electromechanical and gold knot, environmental protection, water conservation, immigration, other professions and the like, and can adopt static retrieval or dynamic retrieval according to the characteristics. The mandatory condition static search refers to that a user searches for a mandatory condition that is valid at a certain time point, and the time point can be either the current time point or the past time point. The mandatory dynamic search of the strip refers to the search of the change condition of the mandatory strip in a certain time period or the difference of the mandatory strip between two time points.
And the mandatory treaty checking method module is used for providing clause content, abstract description, checking key points and methods, case analysis and the like according to mandatory treaty implementation guidelines. The module can search the clause content of mandatory treaty and also can check the mandatory treaty implementation method and guide compiled by expert. In order to facilitate the utilization of mandatory regulations, the module provides a template generation function for mandatory regulations inspection, a user can download inspection results written under a template line, or fill inspection results in a system, the system generates an inspection report and then downloads the inspection report, and formatting input and output reduces errors while ensuring timeliness of the strong regulations.
And the technical standard effectiveness inquiry module is used for realizing standard effectiveness inquiry according to standard catalogues and other industry reference items in the system and texts of the technical standard library.
And the mandatory strip checking module is used for carrying out strong strip self-checking and supervision checking.
The preliminary design quality assessment tool module is used for carrying out the preliminary design quality assessment of the hydraulic and hydroelectric engineering according to the standard SL521-2013, and the module automates the assessment process, the index and the calculation method so that a user can put the point of interest into the business itself.
