Description

A Highway Intelligent Street Light Control System

technical field

The intelligent road lamp control system of the invention belongs to the technical field of measurement and control.

Background technique

With the growth of the global population and the continuous consumption of traditional energy sources, energy and energy issues have become a major issue affecting world peace and even human survival in the 21st century. How to save energy has been widely concerned by all walks of life.

In the transportation system, in order to save electricity, many street lamps are equipped with solar panels. However, the electricity accumulated by sunlight during the day is not enough to maintain electricity at night, and in rainy weather, it is necessary to rely entirely on traditional electricity to maintain road lighting. In this case, how to only control the lighting and closing of street lamps is particularly important.

Contents of the invention

In view of the above technical requirements, the present invention discloses a highway intelligent street lamp control system. The control system grasps the characteristics and rules of the driving speed of the vehicle, and performs automatic and intelligent control on the lighting and closing of the street lamp according to the driving position and speed of the vehicle, so as to realize The technical purpose of saving electric energy.

The purpose of the present invention is achieved like this:

A highway intelligent street lamp control system, including a sign arranged on the vehicle, vehicle identification devices arranged at equal intervals on the road surface, and a street lamp at the same position as each vehicle identification device;

The identification is used to encode the vehicle identity information to realize the uniqueness of the vehicle identity;

The vehicle identity recognition device is used to decode the vehicle identity information, bind the position information of the vehicle identity recognition device, the vehicle identity information and the recording time and send it to the processor, and the processor summarizes the bound data with the same vehicle identity information , control the lighting of street lights through the location information and recording time of the vehicle identification device.

In the above-mentioned highway intelligent street lamp control system, the identification includes a start segment and an end segment, and a code segment set between the start segment and the end segment, and the code segment adopts binary code.

The identification and the vehicle identification device adopt the following scheme: the initial segment, the end segment, and the coding segment in the identification adopt a step structure with ups and downs, and the changing direction of the step structure is perpendicular to the extending direction of the road. The vehicle identification device is The distance measuring device recognizes the identity of the vehicle according to the change rule of the height of the steps.

Beneficial effect:

First, since the present invention is provided with an identification that can realize the uniqueness of the vehicle identity, and a vehicle identity recognition device that can identify the vehicle identity, it can control the calculation process of the parameters relative to the uniqueness of the vehicle identity and exclude the data of other vehicles Interference, which improves the reliability of the data;

Second, in the sign, the change direction of the step structure is perpendicular to the extension direction of the road. When the vehicle changes lanes or even turns, the spacing of the step structure only changes in proportion, so it does not affect the vehicle identification result and increases the vehicle identity. Robustness of recognition.

Third, the control system can automatically and intelligently control the lighting and closing of street lamps according to the driving position and speed of the vehicle, so as to realize the technical purpose of saving electric energy.

Specific embodiment four

This embodiment is an embodiment of an intelligent street lamp control method for a straight section of a highway.

The intelligent street lamp control method for the straight section of the highway in this embodiment is realized on the highway intelligent street lamp control system described in the first specific embodiment, and the method includes the following steps:

Step a, record the time t _i-1 when the vehicle passes the i-1th vehicle identification device;

Step b. Record the time t _i when the vehicle passes the i-th vehicle identification device;

Step c. Calculate the average speed v _i-1 of the vehicle passing through the i-1th road section:

${\mathrm{<span\; class="notranslate">\; v</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; 1</span>}}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; x</span>}}{{\mathrm{<span\; class="notranslate">\; t</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; -</span>{\mathrm{<span\; class="notranslate">\; t</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; 1</span>}}}$
