A detection method of a house settlement monitoring device is characterized by comprising the following steps:

s1, level detection:

one end of the pressure sensor 36 is supported by the elastic element 37, and the other end of the pressure sensor 36 is pressed against the side surface of the foundation 1, at this time, the measurement value of the pressure sensor 36 is F1, when the foundation 1 moves horizontally, the pressure sensor 36 is pushed to move towards the elastic element 37, at this time, the measurement value of the pressure sensor 36 is F2;

by the formula:

in the formula: l is the horizontal offset, F1 is the measurement value of the preceding pressure sensor 36, F2 is the measurement value of the following pressure sensor 36, and K is the elastic coefficient of the elastic member 37;

calculating to obtain a horizontal offset L;

s2, vertical detection:

and (3) carrying out primary measurement after the installation is finished:

controlling the winding assembly 47 to wind, enabling the top of the cone disc body 419 to be propped against the bottom of the movable disc 42, enabling the spring 44 to contract, enabling the cone disc body 419 and the movable disc 42 to synchronously move upwards for a certain distance, then controlling the winding assembly 47 to loosen the line, enabling the cone disc body 419 to move downwards, simultaneously measuring the length of the rope body 421 passing through the rope body 421 of the through type length measuring instrument 45 by the through type length measuring instrument 45, and marking the length measured by the through type length measuring instrument 45 when the induction value of the magnetic induction probe 420 is maximum;

and after a preset time interval, carrying out measurement again according to the same step as the primary measurement, and calculating the difference of the two measurement values to obtain the vertical settlement distance.

Based on the arrangement of the structure, the through type length measuring instrument (Hall element), the power structure (clothes motor) of the winding assembly, the distance detection structure (pressure sensor) and the magnetic induction probe are electrically connected with the controller and are connected with the display and the control key so as to be convenient for carrying out comprehensive control operation.

The working principle is as follows: during horizontal detection, distance monitoring results are generated to the controller at intervals, then the controller transmits the monitored structure to the display 416, and a user directly obtains a measurement structure by observing the display 416 and performs statistical analysis;

during measurement, one end of the pressure sensor 36 is required to be pressed against the side face of the foundation 1 and keep the vertical direction, the orientation of the end part of the horizontal section of the pressure sensor is adjusted by rotating the L-shaped bent frame 33, the extending length of the end part of the adjusting rod 34 is adjusted by relatively rotating the adjusting rod 34 and the L-shaped bent frame 33 (the distance between the adjusting rod 34 and the L-shaped bent frame is screwed in by threads), and one end of the pressure sensor 36 is controlled to be pressed against the side face of the foundation 1;

the vertical detection is performed in a manual control manner, that is, the vertical detection is manually started once by a user (the specific use manner is described above, and is not described herein again), so as to obtain a result, and the result is compared with the results obtained in the previous times, so as to calculate the settlement amount.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
