Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.
Fig. 1 shows a specific embodiment, and fig. 2 shows a settlement observation device for tunnel construction period, including: set up at least one laser range finder, at least one inclinometer, central control module in the tunnel to and set up respectively in the 4G route conversion module and the command portion router of tunnel entrance to a cave, laser range finder and inclinometer are connected with central control module respectively, and central control module gathers laser range finder and inclinometer's parameter information in real time, and transmits for 4G route conversion module and command portion router through optic fibre.
The laser emitted by a laser emitter in the laser range finder is divided into two parts: one part of the phase difference signals passes through the distance L and is reflected back by the measured object to enter the phase difference detector; the other part goes directly to the phase difference detector. The phase difference detector measures the phase difference of the two parts of laser, the distance L between the laser transmitter and the measured object is calculated according to the phase difference value, and the laser range finder is directly fixed in the tunnel by using expansion screws.
The inclinometer is used for measuring the horizontal angle change of the system, and the inclination angle sensor integrates the MCU, the MEMS accelerometer, the analog-to-digital conversion circuit and the communication unit on a very small circuit board and directly outputs inclination data such as angles. The theoretical basis is newton's second law: according to basic physical principles, inside a system, velocity is not measurable, but acceleration is measurable. If the initial velocity is known, the linear velocity can be calculated through integration, and then the linear displacement can be calculated, so that the acceleration sensor is actually an acceleration sensor applying the inertia principle. When the tilt sensor is at rest, i.e. no acceleration is acting in the lateral and vertical directions, then only the gravitational acceleration acts on it. The included angle between the gravity vertical axis and the sensitive axis of the acceleration sensor is the inclined angle. The inclinometer is directly fixed on a wall body in the tunnel.
The 4G route conversion module is connected with the central control module through 500 m optical fibers.
The basic principles and main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and what is described in the specification are only illustrative of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, and these changes and modifications fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
