Description

The audio alert seismometer

Technical field

The utility model belongs to the monitoring instrument field, specially refers to the monitoring instrument that adopts audio alert earthquake motion size.

Background technology

Experienced after the huge disaster of earthquake, people experience the importance to observation, monitoring and forecast before the earthquake arrival more.The observation at all levels of government's level, the main force that oracle is no doubt relied on, if also advance notice is judged in scientific analysis that they can make early, just can reduce disaster and avoid the great loss pain of injury! Also change people's attention more highly simultaneously after the shake and appointed sense, earthquake relief work, Everybody is responsible, later examine the simple and easy monitoring device that adopted already among the people closely, edified the thinking that the design people further improves these easy devices, look back ancient history, China Zhang Heng has just invented first " seismograph " in the world as far back as 132 years Christian eras, be a kind of easy device in order to monitor earthquake, i.e. " seismograph ", after these hundreds of years, just occurred similar seismograph abroad, modern age is because the development of seismic monitoring technology, how domestic once very big notice being placed on improves on seismographic functional parameter and the monitoring technical ability, concentrates data processing of the heart or the like such as the digitizing of seismic monitoring and the data transmission and the data sink of variety of way.For simple can be with the seismometer of monitoring roughly, but less relevance, this has just ignored the common people's energy more widely.The earthquake of Japan is more, and the sound from the common people is paid attention in their some areas, in some hotels seismometer has been installed, and can quote the size of earthquake when earthquake takes place, and generally represents with " seismic intensity ".Seismic intensity is meant people to the sensation of earthquake and a kind of scale of earthquake initiation destructiveness, and the speed or the acceleration of seismic intensity and earthquake motion are relevant, and seismic intensity is 12 degree in the criteria for classifying of China, has produced strong destruction more than general 10 degree.Make foreign things serve china, make the part serve the present, the means of reference for modern scientific development, in conjunction with the concern of the design people to earthquake, grope according to observation for many years, made a kind of audio alert formula seismometer by oneself, can quote seismic intensity with language when earthquake takes place what are, or the speed of earthquake motion, acceleration is in that scope, but do not have propaganda always, uses, after the current Wenchuan violent earthquake, earthquake relief work that unity of will is an impregnable stronghold in the whole nation from the leadership to the masses, we are in line with wanting to allow a little effects of its performance, for meagre power is put in the rough warning of earthquake from now on to the greatest extent, so disclose this patented claim.

Summary of the invention

The utility model technical issues that need to address are, it singly not the effect that only relies on the comparatively perfect digital seismograph device of specialized department of government one-level, but the extensive strength of the whole people's earthquake relief work of having brought into play that unity of will is an impregnable stronghold, just researched and developed a kind of simple in structure, rough seismometer of reporting to the police, goal of the invention of the present utility model is to provide a kind of audio alert seismometer, for realizing the object of the invention, the technical scheme that is adopted is, a kind of audio alert seismometer, comprise an instrument cabinet, cabinet panel is provided with switch indication and digital display screen, it is characterized in that, is provided with one at cabinet inside and comprises speech chip at interior electronic circuit board; The input end of wiring board is connected with seismic sensor and signal amplifier, and amplifier output is connected to comparer and trigger in parallel again, enters the speech chip input port again, and its output terminal is connected with corresponding digital display board and phonetic alarm.

Described comparer in parallel and trigger are divided into 12 grades by the entering signal power, 1-12 numerals of corresponding digital display screen.

Above structure is based on following theoretical analysis: seismic sensor is converted to electric signal to earth vibration signal and amplifies, just can converse corresponding great earthquake acceleration of amplifier output voltage or earthquake speed according to the transducing sensitivity of seismic sensor (claiming the earthquake transducer again) and the amount of gain of amplification, obtain being divided into the seismic intensity of grade thereby can convert.Comparer in the circuit is set different voltage threshold, can establish a shelves arbitrarily, every grade of voltage threshold is corresponding with a certain earthquake intensity value, when amplifier output voltage during greater than the setting value of this grade, comparer just can trigger out a pulse, cause speech chip to emit the corresponding sound of prerecording, as " earthquake 6 degree ", " earthquake 7 degree " and export the corresponding digital shows signal, also can add as voice such as " greater than 60gai ", " greater than 120gai ".

The beneficial effects of the utility model are, this monitoring instrument is simple in structure, and energy savings can receive the signal of earthquake motion at any time during earthquake, quote the size of seismic shock by speech chip, can have voice and numeral to show simultaneously, and is convenient, flexible.
