The invention belongs to the field of bridge structure damage discrimination in a time-varying environment, and especially relates to a bridge cluster structure damage discrimination method based on strain response cumulative distribution function difference. The bridge cluster structure damage discrimination method based on strain response probability distribution function difference comprises the steps that 1, a clustering analysis algorithm based on monitoring strain response data similarity is utilized to divide all bridge monitoring strain response data in a cluster, and a plurality of strain response data categories with similar probability distribution are established; 2, under each data category, a denoising method based on bridge structure strain monitoring data set reconstructionis utilized to effectively improve the calculation efficiency of structural strain massive monitoring data denoising; and 3, under each data category, the influence of the time-varying environment temperature on the structure strain monitoring data is effectively eliminated by utilizing the damage discrimination factor based on the cumulative distribution function residual error, thus realizing the damage discrimination of all bridge structures in the cluster.

The invention discloses a data caching method in a disconnection state of the distributed application of a power dispatching automation system, which is characterized by comprising the following steps of: (1) circularly detecting whether the application of a local system operates in the disconnection state or not by a system operating state detection module, continuously detecting if conditions are not met, and starting a data caching module after the conditions are met, wherein the data caching module includes a historical sampling data caching module, a historical alarm record caching module and a manual operation data caching module according to different caching data types; (2) caching plant station data administrated in a disconnection area, and generating a historical sampling data file; (3) increasing a disconnection label in the content of alarm information during disconnection, and generating a historical alarm record into a data file; and (4) caching various operation information into a local real-time library by adopting different storage modes through the manual operation data caching module. The invention can effectively prevent the loss of system application data during the disconnection, thereby ensuring the integrity of the data.

The embodiment of the invention provides a counter custom filtering method and device and a computer storage medium, a first filtering condition is configured through a filtering parameter table, at least one type of first filtering parameter is configured in the first filtering condition, and the first filtering parameter is converted into a second filtering parameter in a type unification mode;analyzing a second filtering condition according to the filtering parameter table, converting and storing the second filtering condition as a first data structure which is easy to filter locally, andacquiring performance data which comprises filtering indication information; the filtering indication information is processed according to the filtering parameter table, the filtering indication information is stored in the second data structure, the filtering indication information stored in the second data structure is filtered according to the first data structure, the filtering result is recorded, in some implementation processes, a counter can set filtering conditions in a user-defined mode, the filtering function is universal, and the practicability is high. Moreover, the data types tobe filtered can be reduced, and the filtering of filtering parameters of various data types is supported at the same time.

The invention relates to a method for establishing an ECU calibration database based on Excel VBA, which comprises the following steps: converting ECU data into a CVX format file by utilizing INCA software; obtaining text presentation of all types of calibration data, and storing the text presentation in sheet1; copying variables of the same type in the sheet1 into the same sheet, and merging calibration data of all data types into a sheet5; if a plurality of items exist, the steps are repeated to obtain calibration data of all data types of each item, and then the calibration data are merged into the sheet5 of a certain item; the method comprises the following steps of: selecting a plurality of items, sorting according to a FUNCTION name, independently creating a sheet for each function, and copying all variables under the same function of the plurality of items to finish the establishment of a calibration database of the plurality of items. According to the method, the workload of data calibration personnel can be effectively reduced, the possibility of calibration errors is reduced, and meanwhile, the data borrowing precision among projects is improved.

The invention relates to the technical field of data processing, in particular to a device and a method for formatting data contained in a text. To some extent, the device can solve the problems thatin the text formatting process, a data packet needs to be manually generated, a formatting character string needs to be edited, and the data packet and the formatting character string need to be repeatedly modified, and comprises a displayer used for displaying a user interface containing a text; a controller configured to add a data index in a first text, wherein the data index is used for obtaining the position of target data in the first text, the data index comprises a data name and an identifier, and the target data is of a first data type; to reformat and write the first data type of thetarget data at the position corresponding to the data index into a second data type to obtain a second text; and to control the user interface to display the second text containing the target data ofthe second data type.
