Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] The early warning method for abnormal vehicle aggregation provided by the embodiment of the present invention is to divide the area on the electronic map into a grid, and according to the GPS data sent by the vehicle-mounted GPS, when it is judged that the number of vehicles contained in the grid exceeds the preset time period When the preset number of vehicles in the corresponding grid is reached, the warning information of the corresponding grid will be issued.

Abstract

The invention is applied to the technical field of vehicle monitoring and provides a warning method and a warning system for unusual aggregation of vehicles. The method comprises the following steps of: dividing a certain area or an entire area of an electronic map into grids, so that the divided area comprises at least two grids of predetermined shapes, wherein the at least two grids form an external grid; receiving GPS data and determining whether the number of vehicles contained in each grid exceeds the predetermined number of vehicles in a corresponding grid or not according to the GPS data; when the number of vehicles contained in the grid exceeds the predetermined number of vehicles in the corresponding grid in a predetermined time period, sending warning information of the corresponding grid, wherein the GPS data comprises a unique identifier of the GPS and a geographic coordinate information of the GPS, namely, different areas having different vehicle behaviors in one city are taken as independent grids respectively; and each grid can have different vehicle upper limits so as to distinguish vehicle behaviors in different areas, so that the monitoring accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle monitoring, and in particular relates to an early warning method and system for abnormal accumulation of vehicles. Background technique [0002] With the development of our country's economy and the growth of the number of cars and the total number of drivers, the road traffic conditions are becoming more and more complex and deteriorating, which has a great impact on people's life safety. Therefore, it is particularly important to strengthen the supervision of road vehicles. [0003] The current vehicle supervision system collects the positioning signal of the vehicle-mounted GPS terminal and transmits the collected positioning signal to the monitoring terminal through the server in the wireless communication link. The monitoring terminal realizes the monitoring of the vehicle through the GIS system. [0004] The pre-warning method for abnormal gathering of vehicles provided by the prior art uses...
