Description

Technical Field

[0001] The invention relates to a settlement and inclination monitoring system, in particular to an online settlement and inclination monitoring system for an underground area. Background Art

[0002] On July 21, 2005, a collapse accident occurred at the Haizhu City Plaza construction site and a landslide occurred on the south side of the foundation pit. The accident started from the south terminal and expanded to the east and west ends of the south side of the foundation pit, resulting in 3 deaths and 4 injuries. Metro Line 2 was suspended for nearly a day and many surrounding buildings collapsed or were damaged.

[0003] On November 15, 2008, the foundation pit of Xianghu Station on Hangzhou Metro Line 1 collapsed. The accident caused 75 meters of road surface to collapse, causing damage to sewage, water supply and power supply facilities, and resulting in 21 deaths.

[0004] On October 16, 2020, ground collapse occurred near Ganjiakou Station, a closed station on Metro Line 16, near Ganjiakou in Beijing.

[0005] It can be seen from the above accidents that the problems of ground subsidence and foundation pit tilt and landslide have been problems we have to face in recent years. Once an underground tunnel collapses, the casualties are usually very huge.

[0006] The existing methods of monitoring settlement and tilt are basically through manual regular inspections. First of all, the manual monitoring method cannot achieve real-time monitoring. Regular inspections can detect irregular settlement and tilt, and can also predict some collapse problems, but it cannot be foolproof. These monitorings involving people’s property and life safety should be foolproof. The sooner and faster the problem can be discovered, the top priority of the monitoring task. Secondly, the operating level and work attitude of the monitoring personnel have a direct impact on the monitoring results. In some collapse accidents, human factors have ignored certain important factors and caused major disasters.

[0007] Therefore, how to measure the settlement and inclination of underground tunnels in real time and accurately has become a problem we have to face. Summary of the invention

[0008] In order to solve the problems in the above-mentioned prior art, the present invention provides an online monitoring system for settlement and inclination of an underground area, which monitors the settlement and inclination of the monitoring location through an optical transmitter, a first receiver, and a second receiver, and transmits the monitored information to a monitoring station in real time through a photoelectric sensor.

[0024] Preferably, the first light receiving module and the second light receiving module respectively input the acquired light intensity information and distance information into the photoelectric sensor.

[0025] Furthermore, the photoelectric sensor receives the inclination information of the first inclination monitoring module, the inclination information of the second inclination monitoring module, the light intensity information and distance information of the first light receiving module, and the light intensity information and distance information of the second light receiving module, and converts the above information into electrical signals and inputs them into the information conversion module through cables.

In the specific use process, the entire system can have multiple optical transmitters, multiple first receivers 3 and multiple second receivers 4, and the number of optical transmitters 2 is equal to the number of first receivers 3 or second receivers 4.

[0059] The second receiver is used to obtain the tilt angle of the second preset monitoring point and receive the optical signal output by the first optical transmitter and transmit the optical signal output by the optical transmitter to a third receiver;

[0060] The Nth receiver is used to obtain the tilt angle of the Nth preset monitoring point and receive the optical signal output by the (N-1)th optical transmitter and transmit the optical signal output by the optical transmitter to the (N+1)th receiver;

[0061] The system further comprises: an information conversion module 6, an information storage module 8, an analysis and control module 7, a display 9 and an alarm 10;

[0062] The input end of the information conversion module 6 is connected to the photoelectric sensor 5;

[0063] The output end of the information conversion module 6 is respectively connected to the information storage module 8, the display 9 and the input end of the analysis and control module 7;

[0064] The output end of the analysis and control module 7 is connected to the alarm 10 for controlling the alarm 10 to sound an alarm.

[0065] In a specific monitoring process, the first tilt monitoring module 302 and the second tilt monitoring module 402 respectively input the tilt information into the photoelectric sensor 5; the first light receiving module 301 and the second light receiving module 401 respectively input the acquired light intensity information and distance information into the photoelectric sensor 5.

[0072] When the light intensity information respectively obtained by the first light receiving module 301 and the second light receiving module 302 is enhanced in the vertical upward direction, it can be determined that the light emitted by the light transmitter 2 deviates from the initial position. Since the light intensity information respectively obtained by the first light receiving module 301 and the second light receiving module 302 is enhanced in the vertical upward direction of the initial position, it can be determined that the second preset monitoring point 102 has settled relative to the first preset monitoring point 101.

[0073] When the light intensity information respectively obtained by the first light receiving module 301 and the second light receiving module 302 is enhanced in the vertical downward direction, it can be determined that the light emitted by the light transmitter 2 deviates from the initial position. Since the light intensity information respectively obtained by the first light receiving module 301 and the second light receiving module 302 is enhanced in the vertical downward direction of the initial position, it can be determined that the first preset monitoring point 101 has settled relative to the second preset monitoring point 102.
