The invention discloses a strip mine truck traffic flow density reminding method based on density clustering, and belongs to the technical field of truck transportation. The method comprises the following steps: a server side at least inputs a vehicle number and vehicle-mounted terminal number information; the vehicle continuously receives the positioning information in the driving process, converts the positioning information into plane coordinates and sends the plane coordinates to the server side; the server performs polling to obtain position information of each trolley; meanwhile, setting a distance retrieval range and a vehicle number threshold value; density clustering is carried out on the position information of the vehicles, a cluster composed of a plurality of vehicles is obtained, and the vehicle number corresponding to each piece of position information is inquired; according to the method, all the trucks are automatically grouped according to the distances of the trucks through iteration of limited times, the traffic flow density near the grouped trucks is large, and the trucks in the group are warned at the same time. Compared with a traditional method, the method is low in calculation complexity, high in response speed and capable of being suitable for traffic flow density reminding of a large-scale equipment cluster.
一种基于密度聚类的露天矿卡车车流密度提醒方法,属于卡车运输技术领域。方法为:服务端应至少录入车辆车号、车载终端编号信息;车辆行驶过程中不断接受定位信息,并将其转化为平面坐标,发送至服务端;服务端轮询获得每一台车的位置信息;同时设置距离检索范围以及车数阈值;对这些车辆的位置信息进行密度聚类,获得多个车辆组成的集群,查询每个位置信息对应的车辆编号。该方法通过有限次数的迭代,将所有卡车按照其距离远近自动分组,被分组的卡车其附近的车流密度也大,并向组内卡车同时预警。对比传统方法,该方法计算复杂度低,响应速度快,能够适用于大规模设备集群的车流密度提醒。
