Internet-of-things-based expressway active guidance system

Abstract

The invention, which relates to the technical field of traffic safety, provides an internet-of-things-based expressway active guidance system comprising a sensing system, an early warning system, an internet-of-things system, a cloud server and a background server. The early warning system comprises a PLC and a plurality of early warning devices which are distributed and installed on the side edgeof the expressway front and back in the driving direction. The sensing system comprises a radar speed measuring device and a temperature and humidity detecting device; the sensing system is arrangedon the early warning device in the middle; the sensing system uploads data collected in real time to the cloud server through the Internet of Things system. The cloud server forwards the data to the background server, the background server processes and analyzes the data and sends a trigger command to the PLC after concluding that the data is abnormal data, and the PLC controls the early warning devices to send early warning signals at the same time according to the trigger command. According to the invention, the violation vehicle can be effectively warned, the violation information of the driver is prompted to other drivers of vehicles coming from the rear, and the risk of accidents and secondary accidents caused by abnormal driving is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to an active guidance system based on 4G Internet of Things technology and expressways. Background technique [0002] In recent years, with the continuous construction and improvement of the expressway network, the construction of expressways in my country has made great achievements. While expressways have brought people huge economic and social benefits, they have also caused irreparable damage to road traffic safety. serious property damage and casualties. For example, in September 2019, a particularly serious traffic accident occurred in Yixing, Jiangsu Province, resulting in 36 deaths and 36 serious injuries. The improvement of expressway safety management and the establishment of safety facilities are imminent. [0003] According to statistics, low-speed driving and secondary accidents account for a high proportion of high-speed accidents. Especially in rainy and fogg...

Problems solved by technology

[0004] Traditional early warning equipment cannot make active prevention well

For example, the capture device captures illegal behaviors, and the warning screen reminds you to pay attention to safety information. Such reminders cannot directly feed back the driver’s violation information to the party or the rear personnel. Although they have a certain effect, they are all passive. Mostly feel fatigued by such constant reminders

Some early warning screens with speed measurement function, because the speed measurement and early warning are in the same position, when an abnormal vehicle is detected, it cannot give a warning to the vehicle, which is lack of pertinence

Therefore, conventional early warning equipment cannot actively and effectively make early warning and guidance actions
