Description

The invention relates to the field of automated safety monitoring systems for load-bearing structures, structural elements of buildings and structures, as well as areas of likely natural emergency situations. The invention can be mainly used in the creation, operation of automated monitoring systems for especially dangerous, technically complex and unique objects, as well as buildings and structures located in areas of likely natural emergency, in order to determine the safe state of load-bearing structures, structural elements of buildings and structures, operational alerts about changes in their condition and warnings of emergencies.
A known method for determining the stability of buildings and structures (RF patent for the invention No. 2245531), including the excitation of vibrations of the test object at natural frequencies by exposure to it a sequence of shock pulses of small amplitude, measuring vibrations using sensors installed on the object, determining the dynamic characteristics of the object, experimental determination of values surface strength and / or bulk strength, and / or reinforcement parameters of structural elements of the object, and / or settlement, and / or shear and / or roll of the object, and / or the depth of the foundation, and / or its surface strength, and / or its bulk strength, and / or the period of natural vibrations of the soil under the object, and / or around it, measured at least according to the first tone of vibrations, and / or the logarithmic decrement of their attenuation, and / or the level of groundwater, comparison of the obtained experimental values with the data of theoretical models calculated for a given construction of an object and materials of manufacture, and determination of the stability of buildings and structures by the expert method GOVERNMENTAL estimates.
The capabilities of the method are limited by the control of parameters allowing to evaluate the change in the strength of the supporting structures, as well as the need to attract experts for evaluation. The method does not provide a link between estimates of strength changes with the danger of accidents and emergencies in real time and cannot be used in the accident and emergency prevention system.
Also known is a method for remote monitoring and diagnostics of the state of structures and engineering structures (RF patent for the invention No. 227958), characterized by the use of computers as a point of control and information processing. According to the method, a software survey of sensors (measuring transducers) installed in the places of structural diagnostics is carried out, the obtained information is converted, digitized and transmitted to a control point, where the signals are recorded and compared with pre-recorded values, which are used as the data of metrological certification carried out before operation, and the deviation of the received signals is judged on the presence of changes in the controlled parameters. The method allows for constant monitoring of the state of the structure and at any time to obtain information about its condition.
Assessment according to metrological certification does not allow to judge the degree of danger of changes in controlled parameters. The capabilities of the method are limited to control parameters that allow you to judge the change in the reliability of the supporting structures. The method does not provide the possibility of using the real-time emergency and emergency warning system in the system. The disadvantages of this method include the need for a request for information in order to display it on a medium.
There is also known a method of monitoring the state of elements of building structures (RF patent No. 23237105), adopted as a prototype, based on the survey of sensors installed in the places of diagnosis of the structure, the conversion of information received from the sensors and its transmission to the control point, which is made in the form of a computer with software providing, where registration and comparison of the received information with fixed values previously entered into the computer’s memory is carried out; object that repeats its design. At the same time, on the conditional image of the object in places corresponding to the actual location of the sensors, color indicator labels are placed, the aforementioned image with indicator labels is displayed on a computer screen, providing a constant connection of the said indicator labels with sensors, and use as a fixed value for each sensor the maximum allowable value of the measured parameter obtained by preliminary calculations. The results of the survey of sensors and the results of comparing the last information received from them are reflected in real time through the color of the indicator marks and its change in the conditional image of the object. The color of the indicators judges the health of the sensors and the condition of the structure.
The disadvantage of this method is the low probability of identifying pre-emergency and emergency situations due to the inability to recalculate the maximum permissible values of the measured parameters due to aging of structures and the influence of external physical factors.
The capabilities of the method are limited to control values that allow you to evaluate the state change of the elements of building structures. The method does not provide an assessment of the degree of danger of changes in the values of the measured parameters with the danger of accidents and emergencies in real time and cannot be used in the emergency warning system, emergency.

Also known, adopted for the prototype, is a system for monitoring the technical condition of buildings and structures (RF patent for utility model No. 66525), comprising a shock device unit, a vibration sensor unit, a processing and output information unit, an object vibration acceleration measuring unit, and / or a speed measuring unit object vibrations, and / or a unit for measuring amplitudes of object vibrations, and / or a slope measuring unit, and / or a deflection measuring unit, and / or a stress measuring unit, and / or a load measuring unit, and / or an absolute and unequal measuring unit molecular precipitation, and / or control unit of cracks, joints and seams, and / or block geodetic measuring parameters and gradation output information block.
The disadvantage of this system is the lack of the possibility of continuous operation, the lack of the ability to directly measure the natural vibration frequencies of the supporting structures, structural elements of buildings and structures, the lack of the ability to take into account important climatic factors affecting the safety state of the supporting structures, structural elements of buildings and structures - temperature, humidity, level groundwater, lack of monitoring and display of data on changes in the state of load-bearing structures , structural elements of buildings and structures in real time, the lack of a block for transmitting information to external consumers through information networks and / or communication channels, the implementation by means of a block of a shock device only impulsive (shock) dynamic effects on structural elements.
The technical result of the claimed invention is to reliably warn management bodies about the possibility of emergency, emergency situations and their prevention due to timely detection, warning and response.
During operation, buildings and structures are exposed to various factors, under the influence of which they wear out, and the bearing elements lose their bearing capacity. Such factors include seismic effects and vibration loads, the effects of industrial installations, ground and underground transport, periodic changes in temperature and humidity of the environment and the supporting structures themselves, the movement of atmospheric air and groundwater. From constant or periodic exposure to such loads in buildings (structures), stresses and deformations also accumulate, which can at some point in time lead to local destruction of structural elements or progressive destruction of the supporting structures of the building. The operation of buildings with damaged structural elements can lead to catastrophic collapses of buildings (structures), including with great loss of life.
Each building or structure has a set of integral characteristics of the state of load-bearing structures, such as:
- frequencies and forms of natural vibrations;
- magnitudes of displacement amplitudes, displacement velocities and accelerations at measurement points;
- attenuation parameters of structural vibrations;
- transfer functions soil - foundation, foundation - floors;
- components of dynamic deformations, stresses, etc.
These integral characteristics reflect the individual characteristics of the building, as a consequence of the properties of the underlying soil and the foundation of the object, the presence of groundwater, the type and quality of the connections of individual blocks, parts and elements of the object, their physical and mechanical parameters.
For the selected set of integral characteristics of the state of the load-bearing structures using modeling, a matrix of boundary values of the integral characteristics is constructed, which serves to establish the conditions for disruption of normal operation and the pre-emergency change in the state of load-bearing structures.
The aging of a building or structure is accompanied by a decrease in the strength properties of the load-bearing elements and the structure as a whole, which is reflected in the form of changes in the parameters of their integral characteristics, and, as a result, leads to a temporary change in the matrix of boundary values of the integral characteristics of the state of the load-bearing elements.
The essence of the proposed method is as follows.
A computer model of the object is being built, which allows modeling the structure of the building or structure, the real physical condition of the building or structure, including underlying soil and groundwater, as well as the change in this state over time during operation and forming a conditional image of the controlled object that repeats its design.
A computer model of the physical factors affecting a building or structure is being built.
Mathematical modeling of the influence of physical factors on the building / structure is carried out and the calculated values of the integral characteristics of the supporting structures are determined. The points of the supporting structures are determined, which are critical for the safety of the building / structure and which are also the points of diagnosis of the structures. A matrix of boundary values of the integral characteristics of the state of the building / structure is constructed for critical points for normal operation and pre-emergency changes in the state of load-bearing structures.
Using sensors installed at the points of diagnosis of structures, measurements are made of the parameters of structures and their materials, soil, building, and environment parameters, namely, surface strength, volumetric strength, parameters of reinforcing structural elements of an object, precipitation, shear, roll of an object, and depth foundation, its surface strength, its bulk strength, the period of natural vibrations of the soil under the object and around it, the logarithmic decrement of their attenuation, the level of groundwater, moisture the naturalness, temperature, frequencies and forms of natural vibrations of the object as a whole, its blocks and individual structural elements, displacements, displacement and acceleration velocities at each measurement point on the object, logarithmic decrements of attenuation (absorption), transfer functions soil - foundation of the object, foundation of the object - floors and parts of the object in height, components of dynamic deformations and stresses arising in the object, etc.
The obtained parameters reflect the actual physical state of the operating facility as a whole, its blocks and individual structural elements and are used to assess the degree of danger of changing the integral characteristics of the state of structures.
The obtained data of the integral characteristics are compared with the data of the matrix of boundary values of the integral characteristics, which makes it possible to assess the degree of danger of changes in the state of the building or structure and, if necessary, take measures to alert and evacuate people, according to an in-depth examination of the building / structure.
The obtained data of integral characteristics provide the possibility of establishing a connection with changes in the properties of the underlying soil and defects in the structure of the object that occur during operation, and also provide expert data for assessing the safety of further operation of the building / structure, making recommendations on strengthening structures, repair, reconstruction or justification of the need his demolition.
By the value of the deviation of the values of the integral characteristics obtained during the examination of the object from their boundary values, the state category of the building / structure is determined, this information is displayed by various means of display, and it is brought to the attention of users of information.
To adjust the values of the matrix elements of the boundary values of the integral characteristics of the object, the change of which is caused by the aging of the building, the influence of external physical factors of both a seasonal nature and a spontaneous nature, the method provides for the use of special effects on structural elements using continuous loading devices that generate a loading signal arbitrarily given shape and / or frequency. According to the results of processing the responses of structural elements and the building recorded by the sensors to this effect, changes are made to the matrix of boundary values of the integral characteristics of the object.
Thus, the implementation of the proposed method allows you to:
- promptly communicate information about the safety of the building / structure to users;
- provide data for assessing the safety of further operation, the feasibility of repairs, the need for reconstruction or demolition of a building or structure, to develop proposals for strengthening structures;
- use the information obtained to compile statistics on the health of buildings and structures operating in various conditions, to adjust the technical standards for the design, operation, repair and reconstruction of buildings and structures.
