Abstract
The invention discloses a real-time detection system of a bridge stress. The system comprises stress sensors, an MESH wireless node, a mobile communication network and a remote management platform, wherein the MESH is a wireless mesh network. The system is characterized in that stress sensors are connected with the nearby stress sensors or the MESH wireless node so that a network is formed. The stress sensors detect a stress of a surface of the bridge in real time and send the acquired stress data to the MESH wireless node via the nearby stress sensors. When the MESH wireless node receives the acquired stress data, the MESH wireless node further transmits the stress data to the remote management platform via the mobile communication network. The remote management platform analyzes and processes the received stress data. If the stress data detected by the stress sensors exceeds a normal range, the remote management platform is conducted to warn.
Description
Technical field
The present invention relates to bridge stress monitoring and field of wireless transmission, particularly released a kind of bridge stress real-time detecting system.
Background technology
Traditional method is that foil gauge is attached on the determinand, makes its strain along with determinand flexible together, and the metal foil of foil gauge the inside is just along with strain elongates or shortens like this.A lot of metal its resistance when mechanically elongating or shortening can change thereupon, and foil gauge is used this principle exactly, by the variation of measuring resistance strain is measured.By Wheatstone bridge, just the proportionate relationship of this resistance can be converted into voltage, then different instruments can change into the variation of this voltage the data that can measure.This mode is by measuring manually, the stress data that collects passed be stored in the memory card or manual record gets off, then the analysis of manually taking home, the analysis and summary result, whether the stress of judging bridge exceeds normal range, if exceed normal range, then there is certain risk in the running of bridge.This metering system has very large retardance, and the data with gathering that can not be real-time return, and analysis that can't be real-time is judged, makes countermeasure, may cause serious bridge collapse accident in the situation of this delay.
Summary of the invention
Purpose of the present invention is exactly a kind of bridge stress real-time detecting system that provides in order to solve the deficiencies in the prior art.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of bridge stress real-time detecting system, comprise strain gauge, MESH radio node (MESH is wireless mesh network), mobile communications network and remote management platform, it is characterized in that, described strain gauge is dispersed in bridge floor, described strain gauge links to each other with close described strain gauge or described MESH radio node, consist of a network, described strain gauge detects in real time the stress of bridge floor and by near described strain gauge the stress data that gathers is sent to described MESH radio node, after described MESH radio node receives the stress data of collection, further stress data is transferred to described remote management platform by described mobile communications network, described remote management platform is analyzed the stress data that receives, process, judge that the stress of bridge floor is whether in normal range, the stress data that described strain gauge detects exceeds normal range will cause described remote management platform early warning, described remote management platform is according to circumstances made control decision, assigns control command.
Wherein, described strain gauge detects near the stress of its bridge floor in real time, and simultaneously, described strain gauge is built-in with wireless transport module.
Wherein, described MESH radio node receives the stress data that described strain gauge gathers in real time, and compressed encoding becomes data stream, then is transmitted to described remote management platform by described mobile communications network.
Wherein, the stress data that described remote management platform Real Time Monitoring gathers is analyzed, is judged, makes control decision, the stress intensity of control bridge floor.
Wherein, its inside of described MESH radio node is provided with wireless transmitter module, by mobile communications network firing stress data.
Description of drawings
