Disaster monitoring and early warning system of expressway

Abstract

The invention discloses a disaster monitoring and early warning system of an expressway. The system comprises a data acquisition module, a data verification module, a data conversion module, a data classification module, a threshold module and a shape changing module. The data acquisition module is used for acquiring all kinds of real-time data which affects the expressway disasters. The data verification module is used for carrying out format verification and data verification on the real-time data stored in all center servers according to data flows. The data conversion module is used for converting the data subjected to the format verification and data verification into standard data formats. The data classification module is used for classifying the converted standard data formats according to a coding rule. The threshold module is used for setting thresholds of all data which affects the expressway disasters. The shape changing module is used for comparing data flows in the threshold module and a classification database through a data loading module and displaying results in a report and thematic map manner. According to the invention, flexibility and timeliness of monitoringmeans are achieved; monitoring results are quite accurate and reliable; and disaster monitoring and prevention ability in expressway construction processes can be greatly improved.

Description

technical field [0001] The invention relates to expressway disaster monitoring and early warning technology, in particular to an expressway disaster monitoring and early warning system. Background technique [0002] Since the 1980s, our province's transportation infrastructure has achieved leapfrog development and made remarkable achievements. Its outstanding sign is the rapid development of expressway construction. By the end of 2015, the total mileage of expressway kilometers in our province has exceeded 5,000 kilometers, connecting 97 counties (cities, districts) in the province, and there are 21 inter-provincial expressway exits. At the same time, during the "13th Five-Year Plan" period, 28 high-speed construction projects will be arranged, with a total construction mileage of 1,896 kilometers. The total mileage of the province's expressways will reach 6,500 kilometers. At that time, 3 high-speed passages will connect to northern Shaanxi, and 6 high-speed passages will t...

AI Technical Summary

Problems solved by technology

[0004] 1. The traditional high-speed construction theory of deep excavation and high filling leads to a large number of high slopes and high roadbed sections

The high slope makes the mountain severely cut and in an unstable state, and the settlement of the high foundation after high filling will deform the road and bury hidden dangers;

[0005] 2. Long-term attention to the functional factors of expressways (safety, speed, etc.) has resulted in more and more serious damage to the natural environment, especially vegetation damage and soil erosion caused by major projects, changing the dynamic conditions of karst groundwater, and causing ground subsidence Cracks, ground subsidence, etc.;

[0006] 3. During the construction process, due to illegal construction, random digging and dumping of earth and rocks, hidden dangers such as blocking the river course and forming a dammed lake;

[0007] 4. During the construction and operation of the road, due to human activities (such as mining, stone mining, groundwater mining, etc.), the surrounding environment changes and the ground subsidence causes hidden dangers to the road;

[0014] Traditional measurement and perception methods have provided great help to the monitoring of expressways, but with the continuous improvement of monitoring content and monitoring accuracy requirements, traditional monitoring methods have gradually exposed their shortcomings: a large workload in the field , affected by terrain conditions, it is impossible to achieve continuous monitoring on a large spatial scale
