Design and Implementation of Parking Monitoring System of Bike Sharing In the Electronic Barrier
Wei Dong Shen, Jiao Li · 2018
Electric barrier, which is one of the most vital function in GPS auto monitor system demands, has being widely applied in many fields liking bike sharing.This paper presents an intelligent GPS auto monitor system and describes the design and implement of electric barrier on a Shared bike.By means of map matching method and GPS to realize the parking of the Shared cycle in the designated area, it is more effective to use the sharing cycle to facilitate the travel of the mass of people.On the vehicle monitoring map, draw polygons of the electronic fence, when the vehicle in the area to meet the appropriate conditions, can alarm or do some other linkage processing.By using the GPS coordinate of the vehicle and the map information of the electronic fence, the mathematical model is built, and the algorithm is designed.This software is implemented by programming. IntroduceThe sharing cycle refers to the bicycle sharing service provided by enterprises in campus, subway station, bus station, residential area, commercial district, public service area and is a time-sharing rental mode.Bike Sharing is a new kind of sharing economy.With the emergence of various sharing bikes in the market, people travel in a very convenient way.The popularity of this method has greatly improved people's time of appearance.Especially in some big cities, with the increasing number of subway, the urbanization of village is becoming more and more choose shared cycling, connected to the community and, estuary metro subway travel got greatly alleviate the problem of the last kilometer.Shared cycling is the essence of which is a new type of vehicle rental business -bike rental business, mainly depend on the carrier for the bike (bicycle), can make full use of the city because of the rapid economic development of bicycle travel low status, to maximize the use of public roads pass rate, at the same time has the effect of healthy body.But the problem of that followed was the management of bicycles, especially parking problems.How to maximize the use of shared bikes, parking problem is a very worthwhile problem.Here, we can use the electronic fence to realize the parking monitoring of bicycles.Problems existing in the development of this article from the Shared a bicycle, how to standardized management, raises the electronic fence this technology, Shared cycling was introduced in detail, the electronic fence, electronic fence said, storage, map matching and position determination and automatic alarm, and other aspects, and finally introduces the electronic fence in Shared bicycle parking monitoring system in the implementation process.2 Polygon region processing.As shown in fig. 1 the judge point p in the polygon method is: use the level of the point p to coordinate and polygon intersection, get a number of intersection points, if the number of intersection point on either side of the point p is an odd number when, that point p within the polygon, namely the plumb line interior-point method .This method is suitable for arbitrary polygons, including convex polygons and concave polygons, and is suitable for polygons with holes.
