Problems solved by technology

However, the actual situation is far more complicated than the traffic rules stipulate, especially the weather conditions have a great impact on the safe vehicle distance. For example, the braking distance is obviously longer in wet and slippery rainy days than in sunny days, so the safe vehicle distance should be increased to By analogy, there should be different safe car distances in foggy days, snowy days, and at night, but the existing car distance confirmation signs and distance measuring line systems cannot provide corresponding safe car distance confirmation information according to different weather conditions

Embodiment 1

[0030] A kind of expressway safe vehicle distance intelligent indication system provided in this embodiment, such as Figure 1-5 The shown includes the safe vehicle distance confirmation indicator module and the LED distance measuring line module. The distance line module is connected by communication; the safety vehicle distance confirmation indicator module includes a sign and a track guardrail, and the sign is slidingly connected to the track guardrail; the sign includes a display screen, a bracket 9, a base 10, a weather sensor 14, and the track guardrail includes a conductive rail 5; The display screen is fixed on the support 9, the bottom of the support 9 is connected to the base 10, and the weather sensor 14 is installed on the surface of the base 10;

[0031] Such as figure 2 Shown is a schematic diagram of the track guardrail structure, the track guardrail includes a moving rail 1, a guardrail column 2, a screw 3, a baffle plate 4, a conductive rail 5, and an insula...

Embodiment 2

[0042] This embodiment provides an intelligent indication method for expressway safe vehicle distance, including:

[0043] S1. Obtain weather information sensed by the weather sensor;

[0044] S2. Process the obtained weather information to obtain the safe distance of the expressway lane, and calculate the direction and distance to be moved of the current sign according to the obtained safe distance;

[0045] S3. According to the calculated direction and distance to be moved, send a control command to the motor, so that the motor drives the drive wheel to move, so as to drive the sign to move, and record the position information where the sign finally moves;

[0046] S4. Send the recorded position information to the display screen in the sign and the LED ranging line module, so that the display module of the sign displays the current position information, and the height of the LED ranging line corresponding to the sign in the LED ranging line module Bright.

Abstract

The invention discloses an intelligent indicating system and indicating method for safe vehicle distance of expressway. The indicating system comprises a safety distance confirmation indicating module and an LED distance measuring line module, the safety distance confirmation indicating module is arranged beside an isolation belt of the expressways, and the LED distance measuring line module is arranged on the ground of the expressways. The safe vehicle distance confirmation indication module comprises an indication board and a track guardrail, and the indication board is in sliding connection with the track guardrail. The indication board comprises a display screen, a support, a base and a weather sensor, and the rail guardrail comprises a conductor rail. The bottom of the support is connected with the base, and the weather sensor is installed on the surface of the base. And the base is connected with the conductor rail through a power connection bolt arranged in the base. The corresponding safe distance information can be adjusted according to the weather information, a driver can visually obtain the distance from the front vehicle through the LED distance measuring line, and then the driver can adjust the distance to the safe distance in time.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to an intelligent indication system and an indication method for expressway safety vehicle distance. Background technique [0002] The speed of the expressway is fast, and maintaining a sufficient distance between vehicles is the basic guarantee for driving safety. The driver's judgment on the distance between vehicles is often not accurate enough. The purpose of expressway distance confirmation signs and distance measuring lines is to establish a reference and help drivers Determine the safe distance. The "Road Traffic Safety Law" stipulates that when a vehicle driving on an expressway exceeds 100 kilometers per hour, it should keep a distance of more than 100 meters from the vehicle ahead in the same lane. The distance between the vehicles in front should be kept at least 50 meters. However, the actual situation is far more complicated than the traffic rules stipulate, es...
