Remote sensing and early warning system for settlement of urban road subgrade

Abstract

The invention discloses an urban road subgrade settlement remote sensing and early warning system. The system comprises a plurality of collapse sensing devices and a remote early warning information receiver, wherein each collapse sensing device is arranged below a surface layer of a road and has a unique identity identification number; each identity identification number is stored in a signal transmitting module of the corresponding collapse sensing device; the remote early warning information receiver can receive information sent by a plurality of collapse sensing early warning devices at the same time; when any collapse sensing device rolls and / or displaces, the corresponding three-axis vibration module changes the flow direction of current on the corresponding circuit board, and the corresponding power supply of the corresponding signal transmitting module is triggered to start; when the power supply is started, the corresponding signal transmitting module sends the corresponding identity identification number to the remote early warning information receiver through the communication network. The system is advantaged in that the remote early warning function is achieved, automatic sensing and early warning of urban road subgrade collapse can be achieved, the soil body application range is wide, power consumption is low, and maintenance is avoided.

Description

Technical field [0001] The present invention relates to the field of road monitoring, and in particular, to urban road base settlement remote perception and early warning systems. Background technique [0002] With the rapid development of urbanization, the underground space scale is constantly developing, urban road collapse disaster accidents, frequently occurring. Especially in recent years, urban road collapse disasters entered centralized explosive period, wide range, high frequency, causing a malignant collapse accident of multi-person death injury, causing significant life and property losses and harsh social impact, directly threatening the city Harmony and sustainable development. According to the latest statistics of the China Geological Survey, in 2000, there have been more than 1500 ground collapse disasters in more than 90 cities in China. [0003] City ground collapse will cause traffic interruptions, surface buildings collapsed, and endanger passing pedestrians, ve...
