The geomagnetic field is the inherent resource of the earth, provides a natural coordinate system for aviation, spaceflight and navigation, and can be applied to positioning and orientation and attitude control of spacecrafts or ships. The magnetic navigation technology utilizing the earth magnetic field spatial distribution is simple, convenient, efficient, reliable in performance and anti-interference, and is one of essential basic navigation and positioning means in developed countries, for example, the boeing aircraft with high automation degree is provided with a magnetic navigation and positioning system.
With the rapid development of economy, the investment of infrastructure is more and more, and one of the manifestations is road construction. But as the road construction period is generally long, the growth of the road construction period can not keep up with the rapid growth of vehicles, so that the traffic condition is increasingly worsened, which is almost the common fault of all cities. An effective solution to change the current situation of traffic is to establish a perfect traffic monitoring system in the urban traffic management department. The main goal of traffic monitoring systems is to adapt to changes in dynamic traffic conditions. The traffic data are collected and transmitted to a traffic management center, analysis is carried out in the center, and the center controls vehicle access and signal lamps according to the analysis result, so that traffic is managed better; the center can also use the data to take action quickly in the event of a traffic accident. Meanwhile, the management center can transmit the acquired traffic data to a driver, which is beneficial to relieving traffic congestion and optimizing a driving route. The traffic monitoring system can improve the traffic capacity of the existing road, coordinate and process sudden traffic events, and alleviate traffic jam, thereby improving the traffic condition.
