FIELD: the invention refers to the field of seismic prospecting. ^ SUBSTANCE: the mode envisages installation of three accelerometers and two rotary dynamically tuning gyroscopes on a platform oriented in the horizontal plane. The sensitiveness of the axles of the accelerometers are oriented along orthogonal axles of the platform what allows to measure the signals of linear accelerations along all three axles of the platform. The rotary axles of rotary dynamically tuned gyroscopes are placed in the plane of the platform on mutual orthogonal axles. Two rotary dynamically tuned gyroscopes measure angular speeds and angular accelerations on all three axles of the platform. At that in the measured signal of the angular speed of separately taken channel besides the main signal of the angular speed there is a signal of angular acceleration from a neighboring channel. The scheme of division of the signals of angular speeds and angular accelerations allows separate the signals of the angular speed and the angular acceleration for each channel correspondingly. Thus at appearance of seismic danger the block of seismic sensors reacts as on linear, so on angular accelerations a d angular speeds of displacement of the areas of the earth plane. The signals proportional to linear and angular accelerations and also to angular speeds go into the system of signalization and in the calculator where they are integrated. The signals proportional to linear and angular displacements go from the calculator into the signalization system and the base of data for analysis and conducting researches of seismically dangerous zones of the earth surface. ^ EFFECT: the block of seismic sensors can be applied in the systems of warning about avalanches in the mountains, mudflows, wakening of volcanoes. ^ 2 cl, 1 dwg |
