Abstract

The invention discloses a tracking method for an intelligent road warning device based on a grayscale sensor, which provides a road warning device including a grayscale sensor, through which the white warning line on the road surface and the parts other than the white warning line on the road surface are respectively monitored. Sampling, to generate two sampled grayscale analog quantities; perform analog-to-digital conversion on the two sampled grayscale analog quantities, and convert them into two sampled grayscale values; calculate the average of the two sampled grayscale values, marked as the sampled grayscale average ;Detect the grayscale in the forward direction in real time through the grayscale sensor to generate a real-time grayscale analog quantity, and convert the real-time grayscale analog quantity into a real-time grayscale value through analog-to-digital conversion; average the real-time grayscale value and the sampled grayscale Values ​​are compared, and the direction control signal is output according to the comparison result, and the forward direction of the wheel is adjusted according to the amplified direction control signal, so that the grayscale sensor always advances along the white warning line of the road surface; the method of the present invention can complete automatic placement of road warning signs.

Description

technical field [0001] The invention relates to warning equipment for highways, in particular to a tracking method for an intelligent highway warning device based on a grayscale sensor. Background technique [0002] With the rapid development of the national economy, the pace of expressway construction has been accelerated, and a nationwide expressway network has basically been formed. Due to the huge economic benefits brought by the convenience of the expressway, more and more vehicles choose to travel on the expressway, and the car has become a very common means of transportation. The traffic accidents that take place are also becoming more and more frequent. According to statistics, rear-end collision accidents have accounted for more than 70% of the total number of traffic accidents in expressway accidents; especially in serious accidents, the ratio of rear-end collision accidents is higher. At present, the accident rate of expressways in our country is higher than tha...
