Abstract:
PURPOSE: Database construction method and construction method of database of telemetry data are provided to sample, collect telemetry data by telemetry number from Solid State Recorder Telemetry Format. CONSTITUTION: Temporary file is created for temporary collecting of each telemetry data as an 'additional mode' of solid state recorder telemetry. And a solid state recorder telemetry pile is open as 'reading dedicated mode'. Telemetry data stream is divided into creating time, telemetry mnemonic and telemetry value to be read. Telemetry ID that matches telemetry mnemonic stream on a telemetry ID table of solid state recorder is found. The telemetry value is recorded in ASCII in a temporary file that corresponds to a telemetry ID. In an order of increasing number of telemetry ID, numbers are collected in a telemetry value storage file. Therefore, system error occurrence from overload or memory lacking is decreased and a system processing rate is increased.
Abstract:
PURPOSE: A data construction method is provided to easily handle and manage by connecting corresponding values to equal telemetry by collecting different telemetry values to equal telemetry distributed in a storage file and to construct database with creating regarding index information. CONSTITUTION: Telemetry values collected in a temporary file corresponding to telemetry ID are stored in a storage file of telemetry value. A file point value is put in as a value storage poison element value of telemetry value in batch storing of storage file. During storage in a file, data size is measured to be put in as a size element value. A temporary file is created as an additional mode for temporarily collecting telemetry data. And mass memory telemetry file is open as a read only mode. Telemetry data stream within one line is divided into creating time, telemetry mnemonic and a telemetry value to be read. Telemetry mnemonic character stream is compared with telemetry mnemonic character stream on telemetry ID table of mass memory and a matched telemetry ID is looked for. The telemetry value is recorded in an ASCII form in a temporary file corresponding to telemetry ID. The telemetry ID is collected in a telemetry value storage file in increasing order of telemetry ID.
Abstract:
PURPOSE: A dump data sampling and gathering method and a data base construction method are provided to reduce process time by improving sampling method and to enhance process efficiency of a system by reducing the amount of a memory used and avoiding unnecessary intervention of an operational system. CONSTITUTION: For sampling data of dump IDs(Identifications) from dump data, first data of synchronization bytes are sought from a data stream firstly. Then, second of the synchronization bytes are sought from the following data stream. A dump ID is sought from the following data stream. After reading dump data from the following data stream, the data are recorded in ASCII codes in a temporary memory file related with the dump ID. When dump data of the nine dump Ids are stored in a dump data memory file of a CPU(Central Processing Unit), a file point value of the dump data memory file before storage is recorded as a data memory position element value. A dump starting time value and a dump ending time value are sampled and recorded. When pre-generated dump ID data bodies are stored in a file for storing index data of respective dump Ids, dump ID data body node storage position values of CPUs are recorded as file point values before storage. The pre-generated dump ID data body nodes are stored in index data memory files of respective dump Ids in a binary type, and then, file points before storage are recorded as dump ID node data storage position values. If dump ID node data storage values in the pre-generated dump file data body nodes are recorded to all three CPUs of the same time zone, file points before storage are recorded in the index data memory files in the binary type.
