• Figure - 1 The subject of the invention is the view for the valuation system.
• the description describes a valuation system that detects earthquake, flood, fire and similar traumatic histones of concrete structures with its sensors and transforms it into an understandable, measurable and comparable numerical value within a certain systematic.
• FIG. 1 The representative view of the building (1 ) where the valuation system of the invention is applied is given in Figure 1. Accordingly, in the columns, beams and similar sections of the building (1 ), there are many humidity sensors (11 ), accelerometer (12), fire sensor (13) and tilt sensor (14) embedded in the concrete, each sensor records its related data, collects it and transmits it to the data collection unit (10).
• the data collection unit (10) transfers the collected data to a server (20) with a data transmission unit (15), and the server (20) processes these transferred data.
• the system is a completely passive platform.
• the interrogating mobile device sends the energy needed by the concrete embedded system. Measurements recorded with the sent energy are routed back to the mobile device at an appropriate fraction of the frequency to which the energy was sent.
• This method is similar to the backscattering technique in RFID devices. It is a mobile version only.
• this passive device is passive in the transmission of data, it is divided into two in itself.
• the data collection system is also passive. That is, the measurement is made and recorded only at the time of inquiry. When the query is finished, both measurement and recording are terminated.
• the measurements are active and they are equipped with a battery that is considered to be sufficient for its lifetime.
• the device is always kept in deep sleep, except for events that exceed the threshold value.
• Active devices have either battery or permanent supply or alternative energy acquisition methods.
• the buildings where these devices are embedded transmit data 24 hours a day or event-based, if requested.
• Battery- powered devices can be put into deep sleep, if desired, and event-based data processing can be provided.
• the humidity sensors (11 ) which are planned to be located especially on the ground, roof and intermediate floors of the building, are multi-use and increase the humidity counter by one degree each time the determined threshold value is exceeded. Another counter keeps the stopwatch on as long as it exceeds the threshold value of the humidity sensor. In other words, how many times and how long the humidity stays high inside the building is shared with the consumer.
• the accelerometers (12) in the columns measure the column accelerations in earthquakes and similar tremors.
• the accelerometers (12) are placed in a metallic or composite shell to withstand the load on it.
• This strong shell contains the sensor and the card, the shell form does not matter. It can be of any form, for example, a sphere.
• a disposable fire sensor (13) has been developed.
• This fire sensor (13) is very economical and has a structure that is irreversible with heat.
• the fire sensor to be embedded in concrete is housed in a protective shell to withstand the concrete pressure. There are two contact points in this protective shell. This electrical structure, which is prevented from pressing and contacting each other with the wax solidified between them, is used as a fire sensor (13).
• the fire sensor (13) of a building that has suffered a fire only works once and for the last time, recording the fire history.
• Inclination (or steepness) sensors (14) suitable for plumbing will be placed on the columns of the building (1 ) at the first assembly. It is undesirable for the inclination sensors (14) to measure the inclination continuously. The last slope value is the most significant value. However, in order to learn when the slope changes, the registration of the slope sensor (14) can be done if desired.
• the inclination sensors (14) can be duplicated on the building (1 ) as needed. After an earthquake trauma, if a slope shift occurs, this shift is used to warn the consumer or buyer.
• the tilt sensors (14) also measure the resistance of the bars of the iron in the columns of the building (1 ). Thus, the corrosion value can be determined.
• the energy that the earthquake activity brings to the building is used. If the threshold earthquake intensity is not exceeded, no registration or action is taken.
• the earthquake signal a kind of Rainfall systematic or the equivalent earthquake intensity is calculated with the Palmgren-Miner systematic. The trick here is that since the measurement will be made with the accelerometer (12) located on the building and the results will be evaluated, it will be calculated over the acceleration value perceived by the structural system of the building, regardless of the intensity of the earthquake. In this way, it is possible to express the numerical equivalent of the building natural frequency and structure analysis, including the ground structure as a whole.
• BITEX the acceleration consists of humidity and the rate of change in resistance read from the rebar.
• the intensity of the acceleration values in all directions (a x ,a a z ) is taken into account.
• the time (/, ) during which the acceleration is observed is taken as basis. This process is continued until the end of the acceleration generating process.
• Normal humidity values in buildings are entered into the system and displayed with H o . If this norm accepted threshold value H is exceeded, a penalty index is deducted during the time the moisture content exceeds this threshold value.
• the ⁇ , ⁇ 2 and ⁇ coefficients in the processes are weight or importance coefficients. Thus, when the acceleration and humidity calculations do not produce numerically equivalent values, normalization can be made over these coefficients.
• the acceleration values in three directions with the accelerometers (12), the humidity values of the building (1 ) with the humidity sensors (11 ), the corrosion values with the tilt sensors (14) are measured and transmitted to the data collection unit (10). It is transmitted to a server (20) by the transmission unit (15). Subsequently, the acceleration values in three directions measured by the accelerometers (11 ) on the server (20) during earthquake, shaking and similar vibration moments are calculated by the method of the square root of the sum of the squares of a single equivalent acceleration and scaled with a coefficient. Next, there is a AH (humidity difference) value for humidity levels above the optimum humidity level, and it is scaled with a coefficient by calculating how long this value affects the building.
• AH humidity difference
• the corrosion data coming from the tilt sensor (14) in the server (20) are calculated and collected separately over time, and the final corrosion value is normalized with a coefficient.
• the earthquake, humidity and corrosion data normalized with the coefficients are collected in the server (20), and a score/penalty value (numerical magnitude) is obtained.
