The method includes the following steps that firstly, a first temperature sensor located on a first measurement point for monitoring the internal temperature Tboard is arranged on a floorboard; a second temperature sensor, a third temperature sensor and a fourth temperature sensor located on a second measurement point, a third measurement point and a fourth measurement point respectively are arranged on different height layers of a floor beam and used for measuring the average temperature Tbeam of the floor beam; secondly, the temperature difference deltaT between the Tboard and the Tbeam is calculated, wherein deltaT=Tbeam-Tboard; thirdly, when the deltaT is larger than a preset value, a heat preserving layer is additionally arranged for the floor structure; fourthly, when the temperature difference deltaT reaches the largest value and starts to decrease, water is sprinkled onto the floor. The method and system have the advantages that due to the measurement of additionally arranging the heat preserving layer, the temperature difference between the floorboard and the floor beam is reduced, the surface of the concrete floor structure is kept moist by sprinkling water, and finally the floor is efficiently prevented from fracturing in real time.

The component has a strain measurement device (SMD) circuit board (6) arranged parallel to a side wall of a housing capsule. An SMD sensor (10) enables acquisition of temperature of supply air in the housing capsule. The SMD sensor is arranged between recesses (8, 9) of the SMD circuit board and a cooling body (12), where an edge of the sensor is arranged to an air inlet aperture of the housing capsule. The SMD sensor contacts strip conductors (11) between the recesses. The cooling body increases thermal resistance of heat sources of the circuit board.
