Road section speed measuring apparatus

Abstract

The invention discloses a road section speed measuring apparatus. The apparatus comprises a fixed node arranged on a key road section and a mobile node arranged on a motor vehicle. The fixed node comprises a vehicle detector; the signal output end of the vehicle detector is connected with a first microprocessor; the first microprocessor is connected with a wireless sending module and a first memory; the mobile node comprises a wireless receiving module matching the wireless sending module; the wireless receiving module is connected with a second microprocessor; the second microprocessor is connected with a second memory; and the second microprocessor is also connected with the output end of a speed sensor. According to the invention, the fixed node is arranged on the key road section, so that a vehicle speed on the road section can be obtained in real time, and in case of overspeed, the mobile node on a vehicle can record information, thus real-time speed measuring is realized.

Description

technical field [0001] The invention relates to a road segment speed measuring device. Background technique [0002] The 21st century is the era of automobiles. More and more motor vehicles have entered people's lives, bringing convenience to people, but also bringing great hidden dangers to road traffic safety. At present, casualties caused by traffic accidents occur every day. Among the causes of traffic accidents, especially vicious traffic accidents, speeding is undoubtedly the culprit. On different road sections, traffic control departments in various places will limit the maximum speed per hour according to specific road conditions. However, the phenomenon of speeding is still repeatedly banned, and the reason is because of the lack of necessary monitoring methods. Most of the existing speed measurement systems use two vehicle detectors with a certain interval, and judge the vehicle speed according to the running time of the vehicle between the two detectors. However,...

At present, casualties caused by traffic accidents occur every day. Among the causes of traffic accidents, especially vicious traffic accidents, speeding is undoubtedly the culprit. On different road sections, traffic control departments in various places will limit the maximum speed per hour according to specific road conditions. , but the phenomenon of speeding is still repeated, the reason is because of the lack of necessary monitoring means

Most of the existing speed measurement systems use two vehicle detectors with a certain interval, and judge the vehicle speed according to the running time of the vehicle between the two detectors. However, this detection method based on distance-time can obtain It is an average value, not a real-time value, and it is difficult to evaluate the vehicle speed objectively and effectively
