Overweight dynamic detection system and method

Abstract

The present invention discloses an overweight dynamic detection system. The overweight dynamic detection system comprises a buoyancy gauge, a thermometer, a wind gauge, a rainfall detector, a cabinet, a variable information board and a weight detector; the cabinet includes an information receiving unit, an information processing unit and an information transmitting unit which are all in circuit connection with one another; the information receiving unit is used for receiving acquired real-time data; the information processing unit is used for obtaining the overweight information of a bridge based on the acquired real-time data; and the information transmitting unit is used for transmitting the overweight information to the available information board for displaying the overweight information. The invention also discloses an overweight dynamic detection method. With the overweight dynamic detection system and method of the invention adopted, the weight limit value of the bridge can be calculated in real time according to weather data, bridge deformation data and so on, overweight vehicles can be warned timely, the health status of the bridge can be effectively maintained, and the bridge can be prevented from being damaged. The overweight dynamic detection system and method are of great significance for decreasing bridge collapse, ensuring the safety of drivers and decreasing traffic accidents.

Description

technical field [0001] The invention relates to the field of bridge overweight detection, in particular to an overweight dynamic detection system and method. Background technique [0002] In recent years, new bridge collapses have occurred in many places across the country, and the phenomenon of "abnormal deaths" of large bridges has intensified. According to incomplete statistics, in the five years from 2007 to 2011, at least 17 large bridges collapsed across the country, killing 270 people. 111 people were killed, 111 injured and 23 missing. Among the published investigation conclusions of these large-scale bridge collapse accidents, none of them made it clear that the occurrence of the accident was necessarily related to the quality of the bridge itself. Overloading, flooding, and heavy rain were often blamed as the culprits. In the current bridge overweight inspection, in many cases, a load limit standard has been used for a long time. Generally, the load limit standard...

Problems solved by technology

In the current bridge overweight inspection, in many cases, a load limit standard has been used for a long time. Generally, the load limit standard is adjusted after major repairs or large-scale inspections, and the buoyancy of water is rarely considered when adjusting the load limit standard. , temperature, and rainfall on the bridge load limit, so that no accurate bridge weight limit standard was formulated, which led to bridge collapse accidents
