The invention relates to Chinese character encode input method that is constructed by principle design, conversion operation and input operation. The method follows the rules that: the code length is determined by the grades, the order of arrangement is controlled by the structure and the symbol is converted by the code element, as well as observes the transformational rule and the feature conversion mechanism; and the method is a barcode input method of coding inputting characters, words and sentences by inputting the formula Zs = M1+M2+M3+?-Mi = D1D2D3?-Df by using the key according to the code on the basis of the input soft. It contains the programs of grade identification and fixing length, selecting code element, fetching feature switching code, ranging symbol making code, recording output link. It will realize the inter-conversion of code element and replacing symbol conversion realizing element. All the components of all elements are used as code element that would distribute main code elements according to distribution principle. The code element and feature classifies the type to 32 sorts.

The invention discloses a method for verifying electronic fences based on recorder management platform ends and a device for verifying the electronic fences, and relates to a method for verifying the electronic fences and a device for verifying the electronic fences. The method and the device can solve the problem that the real-time processing speed is relatively low, the processing result accuracy is low and the expansibility is relatively poor in existing platform end fence verification. The method for verifying the electronic fences based on the recorder management platform ends comprises the following steps: vehicle coordinates pushed by corresponding reception coordinates of the fence sub-module and vehicle fences correspondingly form new message packets which are pushed to routing fences, the message packets are respectively routed into corresponding passageways by the routing fences according to the fence shape, and the messages in the three passageways are respectively pushed to the corresponding array of the message bus; the message packets are received by the fence verification sub-module and respectively pushed to the corresponding verification module; after the message packets are verified, warning data generated during verification are stored into a database. The method and the device are used for verifying the fences on the platform ends.

The invention discloses a Matlab sparse matrix based power flow fast decomposition calculation method. The Matlab sparse matrix based power flow fast decomposition calculation method is realized at a Matlab platform by adopting the Matlab sparse matrix technology, so that a researcher can test and analyze a calculation result conveniently by using various tools and functions provided by the Matlab. As matrix operation and complex operation are adopted, program codes are reduced, the programming is simplified, the program becomes clearer, and convenience is brought for the researcher to modify the program, debug and improve the program and add new functions; and due to the use of the matrix operation, the calculation speed is also improved greatly. By adopting the Matlab sparse matrix technology in the Matlab sparse matrix based power flow fast decomposition calculation method, the calculation speed is greatly increased; meanwhile, the Matlab sparse matrix is very convenient to use, and the elements of the sparse matrix can be used directly like the row and column number of a full matrix, and design of a sparse storage structure is also unnecessary. The Matlab sparse matrix based power flow fast decomposition calculation method modifies the calculation process of an admittance matrix, and further improves the calculation speed.
