导航系统及其方法Navigation system and method thereof

技术领域technical field

本发明涉及卫星定位与导航通信领域，具体而言，本发明导航系统及其方法。The invention relates to the field of satellite positioning and navigation communication, in particular, the navigation system and method of the invention.

背景技术Background technique

目前，城市的机动车保有量持续大幅增长，城市交通状况不容乐观。道路拥堵已经成为影响群众日常生活的一个难题。为了改善交通状况，各主要城市都成立了交通指挥中心。在城市的主要道路上设置摄像头来获取各个路段的实时路况，并通过电子显示屏、广播等方式发布路况信息，指导机动车合理选择出行路线，以取得疏导交通的目的。At present, the number of motor vehicles in cities continues to increase significantly, and the urban traffic situation is not optimistic. Road congestion has become a difficult problem affecting people's daily life. In order to improve traffic conditions, traffic command centers have been established in major cities. Set up cameras on the main roads of the city to obtain real-time road conditions of each road section, and release road condition information through electronic display screens, broadcasts, etc., to guide motor vehicles to choose travel routes reasonably, so as to achieve the purpose of traffic relief.

但是，上述的交通指挥管理方式是一种粗放式的指挥方式，有着种种不足：However, the above-mentioned traffic command and management method is an extensive command method with various deficiencies:

首先，目前的交通指挥方法，目标是保证道路通畅。所以，其监控道路，并发布路况信息，希望机动车不要集中出现在某个路段上。而机动车驾驶员的出行目的是达到目的地。现有的交通指挥系统，采用广播的方式发布路况信息，不能针对性的向每个机动车驾驶员提供快捷的到达目的地的路线。First of all, the current traffic command method, the goal is to ensure smooth roads. Therefore, it monitors the road and releases road condition information, hoping that motor vehicles will not concentrate on a certain road section. The travel purpose of the motor vehicle driver is to reach the destination. The existing traffic command system uses broadcasting to release road condition information, and cannot provide each motor vehicle driver with a fast route to the destination.

其次，目前的交通指挥方法，只是在主要道路，比如环线、干线、联络线上才设置的摄像头，其不能获取整个城市的实时交通状况。Secondly, the current traffic command method is only a camera that is set on major roads, such as ring roads, trunk lines, and tie lines, which cannot obtain real-time traffic conditions in the entire city.

第三，通过摄像头看到的是道路上车辆数目和拥堵情况，不仅不能对路况进行预测，还具有一定的延迟性。所以，当看到道路已经堵塞的时候，再进行交通疏导，其效果并不理想。Third, what the camera sees is the number of vehicles on the road and the congestion situation, which not only cannot predict the road conditions, but also has a certain delay. Therefore, when it is seen that the road is blocked, the effect of traffic relief is not ideal.

最后，现有的交通指挥系统，发布信息的手段和方式有限，并不能及时准确的将信息发布给每一个需要的机动车驾驶员。Finally, the existing traffic command system has limited means and methods of disseminating information, and cannot timely and accurately disseminate information to every motor vehicle driver who needs it.

正是因为存在着上述的不足，现有的交通指挥系统并不能胜任城市交通和机动车驾驶员指导的任务。Exactly because of the above-mentioned deficiencies, the existing traffic command system is not up to the task of guiding urban traffic and motor vehicle drivers.

因此，有必要提出有效可行的技术方案解决上述问题。Therefore, it is necessary to propose effective and feasible technical solutions to solve the above problems.
