Technical Field

The invention relates to the technical field of bridge monitoring, in particular to a bridge crack real-time detection system.

Background

With the rapid development of national economic construction, more and more large bridges are pulled out of the ground. The large cement bridge is corroded by seawater for a long time and cracks appear in the large cement bridge under the action of complex vehicle loads, so that the resistance of the bridge structure is attenuated, and disastrous accidents can be caused under extreme conditions. Therefore, the bridge management department can invest in a large amount of manpower, material resources and financial resources every year to detect the inside of the cement bridge, and the current detection mainly comprises the steps of carrying out periodic detection through professional equipment by professionals, so that the internal fracture condition of the bridge cannot be detected in real time. But the bridge may be broken and collapsed at any time for various reasons. Therefore, it is necessary to invent a detection system for automatically detecting the internal fracture condition of the bridge in real time.

Disclosure of Invention

The invention aims to overcome the defects of the technology and provide a bridge crack real-time detection system.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a bridge crack real-time detection system which characterized in that: pour the piece including monomer bridge pours the electric wire of the piece internal buried matrix that buries, and the electric wire spills from the both ends that monomer bridge poured the piece, spills position installation shell fragment or paints conductive paste for pour each section monomer bridge after the concatenation between the piece electrically conductive each other, the electric wire is drawn forth at the both ends that the piece was pour to monomer bridge after the concatenation, and one end and alternating current are connected, and the other end inserts the control circuit of relay, the normally open contact and the singlechip of relay are connected.

Preferably, the single chip microcomputer is connected with the background monitoring terminal through the internet of things.

Compared with the prior art, the method has the advantages that the fracture condition in the bridge can be monitored in real time at lower cost, and casualties caused by sudden collapse due to overlarge cracks in the bridge in shorter time can be effectively prevented although the monitored data is not accurate enough.

Detailed Description

The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings. As shown in figure 1, a bridge crack real-time detection system, at present, most of large cement bridges are built by pouring each part of the bridge in advance and then splicing the parts on site, when a single bridge pouring block 1 is poured in a building factory, wires 2 (the diameter of the wires is only used for demonstration and watching in the figure and the size of the bridge is determined) are poured together with a matrix with a certain density when the concrete is poured, the higher the wire arrangement density is, the more accurate the measurement is, the larger the mechanical influence on the bridge is, and the larger the wire diameter is, the lower the sensitivity is, the larger the mechanical influence on the bridge is. After the pouring is finished, elastic pieces are arranged at the electric wires arranged at the two sides of each section of the bridge or materials such as conductive paste are smeared to ensure that each section of the bridge can be mutually conductive after the bridge is spliced, after the bridge is spliced, wires are led out from two ends of the bridge, one end of the wire is connected with alternating current, the other end of the wire is connected with a control circuit of the relay, a normally open contact of the relay is connected with the single chip microcomputer, the method comprises the steps that whether electric wires inside a bridge are disconnected or not and are not conducted are monitored through a single chip microcomputer, if the electric wires are not conducted, the fact that the bridge is cracked is indicated, the electric wires are broken, the electric wires are not conducted, the number of the electric wires which are not conducted reflects the area of the internal fracture of the bridge, after the single chip microcomputer monitors the fracture, data are sent to a bridge management department through the Internet of things, professional sales detection is informed to the bridge management department through professional personnel and professional equipment, and when the bridge needs to be renovated, the electric wires only need to be connected again when in renovation, and then the bridge can be.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
