Road safety monitoring system and land transportation machine tool for same

Abstract

The invention discloses a novel road safety monitoring system combining a sensor and a GPS, which is suitable for being matched with an earth positioning system to monitor public facilities on a road network in an earth range. The monitoring system comprises a plurality of land transportation machine tools, each comprising a land transportation machine tool body; a positioning device used for outputting the position of the earth where the land transportation machine tool body is located and real-time position information; a vibration measuring device for outputting vibration information; a processing device used for receiving the vibration information and the real-time position information and combining and outputting measurement information; a wireless communication device used for transmitting measurement information; a remote servo center, comprising a wireless receiving and transmitting device for receiving the measurement information; a data storage device, used for storing measurement information; and a central control device, used for comparing the earth position in the measurement information with the previous measurement information in the data storage device so as to judge whether the position has abnormal vibration or not. The invention further discloses land transportation machine tool for the road safety monitoring system.

Description

technical field [0001] The invention relates to a road safety monitoring system, in particular to a monitoring system for safety monitoring using land transport equipment passing through the road, and the land transport equipment used in the system. Background technique [0002] The road system has been the necessary infrastructure for the development of human civilization since ancient times. A perfect road system can promote the exchange of culture, goods and funds among the public. Even economic analysis will include the construction of the road system as an indicator of economic growth. One of the factors, its importance to human society is self-evident, and various facilities in the road system will experience natural aging or natural disaster damage over time, and must be regularly inspected and even repaired to ensure their safety. [0003] Among them, the problem of bridges is the most complex and important. Whether it is a road bridge or a railway bridge, because th...

Problems solved by technology

However, the vibration sensor itself also has a service life problem, and sometimes it is accidentally damaged; and not only the vibration sensor itself will have problems, but once the signal transmission system is damaged and disconnected, it will also hinder the transmission of the sensing signal, and it needs to be updated or repaired , it is necessary to dispatch manpower to the scene in order to confirm the crux of the problem on the spot and deal with it

[0005] On the one hand, the location of the bridge itself may be in the wilderness, causing traffic inconvenience. On the other hand, the installation location of the vibration sensor may also cause construction troubles in dangerous places where the bridge is difficult to climb and stand on. Licensed professional technicians perform installation, repair and daily maintenance, which not only increases the burden on personnel, but also makes it difficult to regularly check, maintain or update the vibration sensor, which will further lead to laziness and negligence of the maintenance unit. The break of the bridge caused more than ten casualties, which was caused by the corrosion of the 13 steel cables holding the bridge deck and their anchorage devices, and the failure of the proper monitoring process.

[0006] In addition, the design of new bridges will include the installation and supporting design of vibration sensors and reserved signal transmission lines. Although it can make regular maintenance of vibration sensors more convenient, it is still necessary to set up corresponding vibration monitoring equipment for each bridge. Figure 10 Take the railway network 9 in the Internet as an example, where there are a large number of bridges 90 and the location to be monitored may be quite different due to differences in terrain constraints, geological conditions, and construction ages. Whether it is reliable and whether the roadbed is solid needs to be guaranteed at any time. Therefore, not only the number of vibration sensors 91 used is very large, but also the follow-up maintenance work also requires a large number of professionally trained and licensed technicians to perform, and the maintenance cost is high. Can't improve

[0007] In addition, the track length of railways can be calculated in the hundreds or even thousands of kilometers. Taking the United States as an example, the total length of the railway track in its business transfer is even as long as 240,000 kilometers. The railway passes through various terrain and climate regions, resulting in frequent loss of roadbed Or rotten sleepers and loose track nails and other problems that endanger driving safety. At present, the maintenance of the railway itself mostly relies on a large number of railway workers to patrol on foot or patrol cars at slow speeds. Not only is the personnel cost too high, but also lacks efficiency. In particular, there is a lack of quantitative monitoring data, so the monitoring and maintenance of the railway system is always a big problem for operators

[0008] Many developed countries have generally experienced economic stagnation or even recession for more than ten years. There are a large number of old railway roads and bridges in these countries due to lack of funds and neglect of maintenance and monitoring. For example, in 2018, Genova, Italy Many highway bridges in the United States collapsed due to heavy rain. For example, the Golden Gate Bridge in San Francisco was completed in 1937, the Brooklyn Bridge in New York was built in 1869, and the St. Louis Bridge on the Mississippi River was completed in 1874. It has a history of more than a hundred years and has been built in It was included in the security watch list in 2000, so far there is no reconstruction plan
