Abstract
The invention discloses an intelligent road warning device based on ultrasonic ranging. The intelligent road warning device comprises a warning board, a chassis, n vehicle wheels, a photographing module, a wireless communication module, an electric motor, an electric motor driving module, an ultrasonic ranging module, a control module, a gray level sensor, a stretching module, 2n lifting mechanisms, 2n baffles and a handheld terminal, wherein the handheld terminal comprises a triggering unit and a display unit; the control module comprises a processing unit and a judging unit; and the ultrasonic ranging module comprises an ultrasonic emitting circuit module and an ultrasonic receiving circuit module. According to the intelligent road warning device, a road warning mark can be automatically placed, the all-day working can be realized, and the warning effect is obvious; and the advancing track of the intelligent road warning device can be automatically corrected, so that the intelligent road warning device cannot cross into a normal lane. The intelligent road warning device is convenient and rapid and low in manufacturing cost, and the integral structure is compact.
Description
technical field [0001] The invention relates to warning equipment for highways, in particular to an intelligent highway warning device based on ultrasonic distance measurement. 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 that of ordi...
