Description
Technical field
The present invention relates to unmanned planes to track field, based on hot spot character news method for tracing and is more particularly, to one kind
System.
Background technique
Currently, unmanned plane starts to be put to more and more fields with the rapid development of unmanned air vehicle technique.Unmanned plane
It is most initially as a kind of very convenient, and the unmanned machine of low-risk, to be usually used to applied to army and do unmanned plane and detect
It looks into, the work for monitoring and combating terrorism, for example " predator " in the U.S., Chinese " pterosaur " etc. are all military unmanned air vehicles.
After unmanned plane enters civil field, the climax of Development of UAV is welcome, as the great Jiang Science and Technology Ltd. of China Shenzhen opens
The big boundary unmanned plane of hair is even more the fame whole world, has also driven the development of unmanned plane type, has there is agricultural watering unmanned plane, forest fire
Monitor unmanned plane, unmanned plane of taking photo by plane etc., express delivery with take out industry all in the corresponding unmanned plane of exploitation.
However, mobile terminal reading news has become the habit of people, traditional news in today of information age
Media method starts to decline, and just to news industry, more stringent requirements are proposed for this, and timely social focus news is not only wanted also to have
Acquire the convenient channel of news.
The news collection mode in general urban district has reporter street to set foot-point, and citizen's proactive contact reporter and public security department contact
A variety of modes for obtaining news cannot many times obtain accurate and timely information but due to reporter's limited amount in time,
Will result in news lose, out-of-date or valueless news etc..What news was particular about is timeliness and accuracy, and the prior art is adopted
Mode set is not good enough in this respect, also inconvenient, and the enterprise for being unfavorable for being engaged in news report reduces the cost for acquiring news.
Summary of the invention
The purpose of the present invention is to solve the problemss of the above-mentioned prior art, provide a kind of based on hot spot character news
Method for tracing, system, unmanned plane and storage medium.
The purpose of the present invention is achieved through the following technical solutions：
