【Technical field】

The utility model belongs to the field of traffic safety, in particular to an automatic reminder system when a motor vehicle passes a crosswalk.

【Background technique】

Pedestrian crossing refers to the walking range where pedestrians cross the lane marked with zebra crossing or other methods on the lane. In order to improve the efficiency of road traffic and alleviate traffic congestion, the traffic management department adopts pedestrian crossings without signal light control in sections with few pedestrian crossings. According to the law of our country, when a motor vehicle passes a crosswalk controlled by no signal lights, it must abide by Article 47 of the Road Traffic Safety Law of the People's Republic of China. OK. However, in recent years, accidents of pedestrians being hit by vehicles on crosswalks without signal lights have occurred frequently. The pedestrian's line of sight is blocked, and when the pedestrian suddenly appears in front of the driver, it is too late to react and an accident occurs.

Therefore, in order to ensure that pedestrians cross the crosswalk safely, it is necessary to inform the driver in advance that there is a crosswalk ahead and whether there are pedestrians on the crosswalk, and to prepare the driver to slow down and stop in time to give way. In my country's existing patented technology, although there are related crosswalk early warning devices, most of the technical solutions have defects: for example, some early warning devices set up display screens, signs, etc. outside the car to remind the driver, but When encountering bad weather such as rainy day, snowy day, foggy day, smog and night, it is difficult for the driver to find the existence of these reminding devices, so just can't reach the effect of carrying out safety reminder to the driver; Also, these cars External display screens, signs, etc. may cause visual distraction for the driver and increase the driving burden.

Regulation;

When the driver's sight is blocked, the system can also promptly and accurately remind the driver that there are pedestrians passing on the crosswalk, so that the driver is ready to stop and give way, effectively avoiding accidents;

The utility model system only uses the smart watch worn by the driver and the high-definition digital camera beside the crosswalk, the technology is mature, the cost is very low, and it is beneficial to popularize and use;

It realizes the reminder of the pedestrian crossing to the driver in the car, which works reliably and is less affected by man-made and weather.

Further, the image acquisition range of the video tracking unit can completely cover the entire crosswalk without affecting the passage of vehicles and pedestrians.

Furthermore, the image processing unit uses the Wear 2100 processor built into the smart watch. As a new generation of smart watch processing chip, it has small size, low power consumption and strong performance; and the image recognition algorithm embedded in the image processing unit can Effectively identify the position and motion status of pedestrians on the crosswalk.

Furthermore, the wireless image transmission module is a 5.8G ZDY WIFI module, which has long transmission distance, stable signal and high image transmission quality, and can quickly connect to long-distance specific WIFI signals.

Further, the WIFI module and the wireless image transmission module are respectively arranged in the smart watch and on the video tracking unit, and the function is to transmit the crosswalk image information collected by the video tracking unit to the smart watch on the driver's wrist in real time.
