Problems solved by technology

However, at present, large-scale underground structure damage identification still relies on sensors such as traditional levels, total stations, earth pressure sensors, pore water pressure gauges and accelerometers to sense changes in the structure, and then calculate the safety index of the structure, because these sensors are active sensors , requires external energy to work, and the level instrument, total station and other equipment also need manual operation, so the traditional geotechnical engineering monitoring method is increasingly unsuitable for the fast and real-time monitoring requirements of modern large-scale underground structure safety monitoring
[0003] In the monitoring signal processing, the traditional processing mode needs to perform secondary calculation on the characteristic signals collected by the sensor, and then analyze and judge the processing results according to the soil and structure finite element or analytical model, and then compare them, and finally obtain the structural safety behavior , so the traditional safety monitoring data processing system for large underground structures is huge, has high requirements for sensors and data acquisition equipment, and the data acquisition system is complex, which makes the reliability, redundancy, durability and maintainability indicators of the monitoring system difficult. Not satisfactory, especially the complex prediction calculation of rock and soil deformation, such as kalman filter prediction method, neural network rock and soil displacement prediction, random subspace method, time series method, wavelet analysis and other signal processing methods, as well as the comparison and comparison of rock and soil three-dimensional calculation in the later stage It is predicted that the real-time performance of geotechnical monitoring will be greatly disturbed or even deteriorated, and the monitoring results cannot be provided to people and various mechanical equipment entering the underground structure in time, so that the underground structure monitoring loses its real monitoring significance
[0004] In addition, in various disasters such as earthquakes and explosions, the most frequent secondary disaster is power outages, and various monitoring instruments and equipment cannot work after power outages, which will greatly hinder structural assessment and subsequent rescue.

Abstract

The invention provides a color-sensitive sensor for providing reliable monitoring for the subsurface structure damage process. In the color-sensitive sensor, a power supplyenergy resourced supplied by the outside is are not required, the pressure bore borne by the color-sensitive sensor is converted into the color by using the characteristic of emitting light of the self material due to the force and the structure safety status can be directly and quickly fed back without the processing of signals. For a monitoring area requiring structure early warning, an additional data acquisition unit is arranged on the sensor, the acquired signals are accurately and wirelessly transmitted to all people and mechanical equipment entering the subsurface structure in real time by using a monitoring system; meanwhile, the signals are transmitted to a control center and provide important field structure information for the subsurface structure all lift life cycle monitoring and the subsurface engineering advanced construction technology. The technical scheme comprises a pressure color-sensitive sensor and a production technology thereof, an installation technology of the pressure color-sensitive sensor and a monitoring system of the pressure color-sensitive sensor.

Description

technical field [0001] The invention belongs to the technical field of sensor development and application, and in particular relates to a color-sensitive sensor production and installation process and a monitoring system for real-time monitoring of the damage development status of large-scale underground building structures. Background technique [0002] The unique anti-disaster ability of underground building structures makes underground structures increasingly become an important way to rationally utilize land resources; The monitoring system established in the early days has gradually entered the service stage in the later years, coupled with the newly built underground engineering and the development of new underground construction technology, these are in urgent need of reliable geotechnical monitoring technology. However, at present, large-scale underground structure damage identification still relies on sensors such as traditional levels, total stations, earth pressur...
