Monitoring and early warning device and method of preventing city road vehicle rear collision under haze pollution

Abstract

The invention provides a monitoring and early warning device of preventing city road vehicle rear collision under haze pollution, comprising a haze information collection module, a vehicle distance information collection module, a vehicle speed information collection module, a storage module, a control module, a monitoring early warning module and a display module, wherein the control module is used as a core module for controlling the function realization of the haze information collection module, the vehicle distance information collection module, the vehicle speed information collection module, the storage module, the monitoring early warning module and the display module; the monitoring early warning module is used for performing information processing on the information of the storage module, determining whether to perform monitoring through collected haze information, calculating a vehicle speed to define a safe vehicle distance, comparing the safe vehicle distance with a collected actual vehicle distance, and determining safe or not; after early warning, the display module displays early warning information. The invention provides a monitoring and early warning method of preventing city road vehicle rear collision under haze pollution.

Description

technical field [0001] The invention relates to the technical field of vehicle rear-end collision prevention monitoring and early warning in harsh environments, in particular to a monitoring and early warning device and method for preventing urban road vehicle rear-end collision under haze pollution. Background technique [0002] In recent years, with the rapid development of urban industry, my country's economic level has been continuously improved, but at the same time it has also brought serious environmental problems. For example: the number of haze days has remained high. When the PM2.5 concentration and relative humidity of the smog reach a certain level, the visibility of the road will be reduced, which will easily lead to traffic accidents. In order to reduce the frequency of rear-end collisions on urban roads under smog pollution, vehicles need a monitoring and early warning device to prevent rear-end collisions to remind drivers to take relevant measures in time t...
