Intelligent building balance detection system and method based on infrared temperature measurement

[0028]Example 1

[0029]The traditional method of building balance detection is mainly to perform balance detection during the construction phase. Due to the severe constraints of the construction site, the theodolite orthogonal vertical projection calibration method is difficult to implement smoothly. The use of a prism-free total station for building balance detection also exists The point is difficult to determine. At the same time, because these observation methods need to be implemented at observation sites higher than buildings, and nowadays, buildings in my country are getting taller, it is difficult to implement them during the construction phase, and there will be no further inspections after completion. The invention judges the building balance by detecting the surrounding environment temperature. When the surrounding environment temperature is consistent, the building is in a balanced state. When the surrounding environment has a temperature difference, it means that the building has subsided. Especially in mountainous areas, landslides may cause rapid building settlement or tilting, or coastal areas are mostly soft ground with soft geology, and buildings are susceptible to rapid settlement due to the influence of the land environment. In these environments, the detection of building settlement or tilting is particularly important, especially after the building is completed, it is necessary to prevent rapid settlement or tilting of the building.

[0030]In this embodiment, asfigure 1 As shown, an intelligent building balance detection system based on infrared temperature measurement includes a horizontal positioning unit, a temperature detection unit, a balance observation unit and a signal emission unit;

[0031]The horizontal positioning unit determines that the infrared receiver of the temperature detection unit is in the same horizontal position;

[0032]The temperature detection unit, including multiple infrared receivers, is set in a circle on the outer wall of the building at the same level to detect the ambient temperature;

[0033]The balance observation unit judges the current building balance state by judging whether there is a temperature difference in the ambient temperature detected by the temperature detection unit;

[0034]The network transmission unit, connected to the network, updates the balance observation results every day, and sends them to the cloud for recording.

[0035]In a further embodiment, the infrared receiver of the temperature detection unit is installed on the outer wall of the building to detect the ambient temperature outside the building wall, because the wall needs to be judged by detecting the ambient temperature at the same level. Whether the body is tilted, so you need to pay attention to whether all infrared receivers are at the same level during installation. In order to solve the problem that all infrared receivers can be at the same level, a horizontal positioning unit composed of level meters is designed. Each infrared receiver is connected to a level meter, and the infrared receivers are determined to be at the same level through these level meters.

[0036]In a further embodiment, the infrared receiver is installed on each external wall of the building to ensure a circle around the building, to detect the ambient temperature of each wall, and to understand the ambient temperature in all directions of the building. The ambient temperature at the same altitude is the same, and the ambient temperature decreases with the increase in altitude. When the building sinks, the altitude of the settled wall decreases. The infrared receiver on this wall detects the ambient temperature than other infrared receivers on the wall The detected ambient temperature should be high, and the temperature difference in the test results proves that the building has subsided.

[0041]One end of the resistor R11 is respectively connected to the other end of the resistor R10, the output end of the operational amplifier U1:C, and the non-inverting input end of the operational amplifier U1:D, and the inverting end of the operational amplifier U1:D The input terminals are respectively connected to the output terminal of the operational amplifier U1:D and one end of the resistor R12, and the other end of the resistor R12 is respectively connected to one end of the resistor R14, one end of the resistor R15 and the operational amplifier U2: the inverting input terminal of A is connected, the other end of the resistor R14 is connected to one end of the adjustable resistor VR1, the other end of the adjustable resistor VR1 is grounded, and the operational amplifier U2: the non-inverting input terminal of A Connected to one end of the resistor R13, the other end of the resistor R13 and one end of the resistor R17 are both grounded, and the output end of the operational amplifier U2: A is connected to the other end of the resistor R15 and the resistor R16 respectively.

Is connected to the other end of the operational amplifier U2: A and the other end of the resistor R18 is both connected to a detection signal.

[0042]In this embodiment, because it is necessary to detect the ambient temperature, it is decided to use non-contact measurement. In the experiment, infrared temperature measurement is used to detect the temperature. Infrared temperature measurement judges the temperature of the surrounding environment based on the infrared rays of the surrounding environment without disturbing the temperature distribution.

The first-stage amplifying circuit in the multi-stage amplifying module is impedance matched by a voltage follower composed of the operational amplifiers U1:D, and the output voltage is changed by adjusting the resistance value of the adjustable resistor VR1. The second-stage amplifying circuit is composed of the operational amplifier U2:A to form a proportional adder. By adjusting the resistance value of the adjustable resistor VR2, the amplification ratio corresponds to the first-stage amplifying circuit. The third stage amplifying circuit is composed of the operational amplifier U2:B, and the corresponding amplification factor is determined by adjusting the resistance value of the resistor R18. The final test data obtained meets expectations.

[0044]In a further embodiment, the daily balance observation result is saved locally and uploaded at the same time, and the local saved data is cleared the next day to update the observation result and save again, saving system memory capacity.

[0045]In a further embodiment, the observation result is uploaded to the cloud, and the cloud receives the data and saves it. When the cloud receives the temperature difference data, it sends an alarm signal to the bound smart terminal.
