DESIGN AND REALIZATION OF MINE HYDROLOGICAL ALARM SYSTEM BASED ON TTS AND FILE COMPRESSION TECHNOLOGY

摘要

Underground coal mine is one of the main hazards of groundwater, the safety of coal mine production has a significantsafety hazard. However, there are some deficiencies in the current automatic monitoring and warning system of Mine Hydrology.First, general automatic monitoring system can not be timely and effectively find the occurrence of sudden flood; second, testingcycle is long, there are amount of data, large occupied storage space.In this study, it was the foundation of hydrological alarmsystem research lied in prompt and effective returning of alarming information and less-space storage for such data. In order tomeet its operating requirements, the design of its alarming unit adopted text-to-speech technology or TTS((text to speech),development package of Chinese language, TTS engine and Microsoft foundation classed to announce its alarming messages.Second, for less-occupied space of storage, the design employed file compression method based on LZMA algorithm, whichcompresses audio files containing alarm information into self-defined files and save them in its disks. In the process of applicationtest, the result show that the design of alarming unit can timely service its abnormal sensors to make it functional, detect theirabnormal parameters in advance, conduct inquiry into such data, read and record early alarming message and perfect thefunctions of hydro-alarm system.Hence, the study results demonstrate that it can play a positive role in ensuring coal mine safetyand production.
