At present, the detection of this danger is mostly in the manual stage. Usually, close-range detection instruments are used to enlarge the crack and then detect the width. The length of the crack is obtained by inaccurate measurement or estimation. This method requires the detection personnel to rely on the road. Inspection or manual inspection is carried out regularly with manual equipment, which requires high work intensity, high inspection costs, and high requirements for personnel safety; and although small cracks in the bridge part that meet the concrete crack limit standards are found during manual inspection, after a period of time, The change of cracks has not been paid attention to. When the harsh environment and load increase suddenly change, the cracks will suddenly expand when the sm

[0031] Example
[0032] like figure 1 , figure 2 As shown, the bridge crack real-time monitoring and rapid early warning device includes: a horn 1, a safety railing 2, a binocular vision sensor 5, and a combined binocular vision sensor component 8. The bridge structure comprises: pier 3, bridge lower deck railway 6, bridge upper deck road 7, bridge guardrail 11, for the convenience of expressing the position of each parts of whole invention, figure 1 The bridge in simplifies the remaining length of the bridge body, and a safety railing 2 is installed at both ends of the bridge, and a horn 1 is installed on each safety railing 2 .
[0033]A binocular vision sensor 5 is installed at intervals on the top of the bridge guardrail 11, and the interval distance depends on the acceptable visual maximum distance of the overall structure of the bridge and the camera of the binocular vision sensor 5, such as the height of the bridge guardrail is 10 meters, and the bridge width is 12 ...

The invention discloses a bridge crack real-time monitoring and quick pre-warning device which comprises binocular vision sensors, loudspeakers, safety railings and a monitoring system. The lower portion of the bridge face between every two piers of a bridge is provided with a combined binocular vision sensor part, the binocular vision sensors are arranged on the top of a bridge protective handrail at intervals, information collecting results of all combined binocular vision sensor parts and the binocular vision sensors are transmitted to a monitoring main machine remotely in a wireless mode, the two ends of the bridge are respectively provided with one safety railing, and each safety railing is provided with one loudspeaker. The bridge crack real-time monitoring and quick pre-warning device can monitor and judge the size of a crack of the bridge and the dangerous level of the crack in real time, and can monitor sudden enlargement of the small crack in real time so as to enable vehicles on the bridge to pass or stop, and the ability to monitor and prewarn sudden dangers is improved.
Description
technical field [0001] The invention relates to the field of bridge monitoring, in particular to a real-time monitoring and rapid early warning device for bridge cracks. Background technique [0002] Concrete is the most widely used building material in building frames. Modern scientific research and application of concrete shows that cracks cannot be avoided in bridges with concrete material structures. At present, the detection of this danger is mostly in the manual stage. Usually, close-range detection instruments are used to enlarge the crack and then detect the width. The length of the crack is obtained by inaccurate measurement or estimation. This method requires the detection personnel to rely on the road. Inspection or manual inspection is carried out regularly with manual equipment, which requires high work intensity, high inspection costs, and high requirements for personnel safety; and although small cracks in the bridge part that meet the concrete crack limit st...
