“The Base Seismosystem” for registration, infraflow-frequency random processes analysis, and decision making which enables to obtain and analyze information contained in infralow-frequency processes.

It is known that random oscillatory processes of mechanical nature play a major part in happening of disastrous situations (earthquakes, tsunami, resonance vibrations of railway bridges, gas and oil pipelines, atomic electric power stations, and other industrial and residential structures). Of particular interest are these processes in infralow-frequency range (10^-3-10) Hz since they spread for long distances and with a higher speed than high-frequency ones and carry a lot of valuable information which enables to create forecasting, preventing and protecting systems.

On the basis of “the Base Seismosystem”, according to the consumer’s order, stations are completed for solving the following problems:

a) seismological situation analysis;

• -on the ground,
• -in a well under the ground,
• -at the bottom of oceans, seas;

b) tsunami notice;

c) control over vibration of bridges, pipelines (including submarine) and other structures in the event of danger of destruction of the construction;

d) atomic electric power stations protection with automatic switching-off their blocks (according to the customer’s instruction) in the event of danger caused by nature or technogenic catastrophes (earthquakes, including slow ones, nuclear explosions and other great power impacts).

The newness of “the Base Seismosystem” is in the use of a non-traditional system of primary information transformers and in a reasonable choice of informative signs never applied before, as well as of a number of new technological solutions which allow to rebuild “the Base Seismosystem” with the purpose of the use under various conditions (the sea bottom, the ground, a mine (well) and for solving other problems.

The system has no analogues in the world practice in the following attainable specifications and other characteristics:

• -frequency range - 0.001-10 Hz;
• -probability of right revealing of a given process against a noise background - not less than 0.9;
• -probability of false work - not more than 10^-8;
• -universality of operating conditions and in the range of solutions solved.

In the known foreign tsunami notice stations, the probability of a false alarm is approximately 10^-1 which involves substantial expenditures on the evacuation of the tsunami-dangerous region. At the same time, the probability

of right revealing is not more than 0.8. A station made in USA costs about $1 million.

Application fields, except the above-indicated, are in those industries where interest is warranted for force impacts of random infralow-frequency processes, in particular, in solving environmental problems in the regions adjacent to high-speed railroads. The modification for individual use in regions of high seismic activity is realized relatively simply.

The base model (a trial sample), as well as separate units for completing various modifications have been developed, made, and tested. Pilot production of the most important units has been mastered.

The checkups and tests were carried out at seismostations in the towns of Borovoye and Obninsk, in Mikhnevo settlement, and in sea conditions in the Pacific Ocean and Black Sea.

A number of principles and technological solutions used in “the Base Seismosystem” have patent purity and are subject to patenting in the RF and in the investor’s country.

The system’s high parameters, the newness of operation principles - with a lower cost, as compared to foreign models - allow to forecast profitability of its production under the conditions of the North-West Region, especially, those of St. Petersburg. For that, it is advisable to establish a joint venture. It is desirable to effect licensing and patenting which would allow to make official the activity on manufacturing, selling and operating “the Base System”.
