The present invention provides a questionnaire identification method, device and equipment, by obtaining the image questionnaire corresponding to the questionnaire, extracting the features of the image questionnaire, inputting the features of the image questionnaire into a classifier model, and obtaining the classifier model The output template type; according to the preset template parameters corresponding to the template type, the image questionnaire is segmented into regions to obtain at least one region to be recognized, and the characters in the at least one region to be recognized are recognized to obtain a recognition result , realize the automatic identification of paper questionnaires, improve the identification efficiency of questionnaires, in addition, because manual input is not required, input errors caused by manual input are avoided, and the accuracy of questionnaire information collection is improved.

The present invention proposes a global-scale hydropower generation capacity assessment method based on the global hydrological model. The method includes collecting hydropower station information and building a global hydropower station database; comparing with the characteristic information of the embedded reservoir in the global hydrological model to obtain the reservoir capacity of the hydropower station Sequence; extract the runoff sequence at the dam site simulated by the global hydrological model; determine the power generation flow of the hydropower station; calculate the power generation head of the hydropower station according to the dam height, maximum head and reservoir capacity of the hydropower station; simulate the global hydropower production. The method of the invention overcomes the dependence of traditional hydropower simulation on detailed characteristic data of the power station, and can estimate the power generation flow and power generation head of the hydropower station only based on the hydropower station database and hydrological model, and then simulate and evaluate the hydropower generation capacity on a global scale. This method can be applied to assess the potential impact of climate change on hydropower energy, and can also be coupled with meteorological remote sensing data to achieve dynamic monitoring and prediction of global hydropower production.

The invention relates to a logistics receiving method. The method comprises the steps of: detecting whether a connectable electronic scale exists or not; if the connectable electronic scale exists, establishing connection with the electronic scale; receiving weighing information sent by the electronic scale; detecting whether scanning information sent by scanning equipment is received or not; and if the scanning information sent by the scanning device is received, storing the scanning information and the weighing information in an associated manner. Therefore, when the weighing result of the express parcel is obtained, the scanning information of the express parcel can also be obtained, and association of the two kinds of information is completed, so that the operation step that a salesman carries out weighing and then carries out input is reduced, the receiving efficiency is improved, input errors possibly caused by manual input are avoided, and the accuracy of the receiving information is ensured.
