Description

A Pedestrian Crossing Intelligent Control Scheme

technical field

The invention relates to the field of intelligent transportation, in particular to an intelligent control scheme for pedestrian crossing.

Background technique

With the increasing number of cars, traffic safety issues are more and more worthy of attention. In real life, it is not uncommon for pedestrians to ignore traffic laws and run red lights. This not only poses great personal danger to pedestrians, but also causes inconvenience to passing vehicles. However, the current traffic light traffic system does not have any supervision or control on the phenomenon of pedestrians running red lights, and when there are very few vehicles on the road (such as late at night), pedestrians still need to wait for the switch of traffic lights if they want to cross the street, which makes pedestrians waste time and Reduced road utilization.

In order to solve this kind of phenomenon, the present invention provides an intelligent control scheme for pedestrian crossing, which can make the existing pedestrian crossing traffic system more humanized and intelligent, and integrate pedestrian crossing request, road vehicle detection, illegal vehicle license plate, road voice Remind and save uploaded data and other functions.

Contents of the invention

The purpose of the present invention is to avoid the occurrence of traffic violations such as pedestrians running red lights indiscriminately, and proposes a more humanized pedestrian crossing intelligent control scheme.

In order to realize the above-mentioned system functions, the present invention adopts the following technical solutions to realize:

A pedestrian crossing intelligent control scheme provided by the present invention is composed of a main control unit module, a data acquisition module, a control module, a voice module, a display module, a remote monitoring interface, and a power supply module, wherein:

Described main control unit module is the minimum system that is made up of STC12C4052AD single-chip microcomputer, reset circuit, crystal oscillator;

The data acquisition module includes a YJ0411 ground induction coil type vehicle detector, an HC-SR501 human body infrared sensor, and an OV9655 camera module;

The control module is mainly a pedestrian crossing request button;

Described voice module refers to ISD4004 single-chip voice recording and playback circuit;

The display module is a three-color LED traffic light of red, green and yellow, and an eight-segment digital tube;

The power module provides power to each module respectively;

The remote monitoring interface is a host computer interface written in C#, which can display the traffic position of the main control unit by calling the Baidu map API, and call SQL Server to save the road condition information.

The pedestrian crossing intelligent control scheme provided by the present invention judges whether there is a pedestrian crossing request through the STC12C4052AD single-chip microcomputer of the main control unit module. If the number of vehicles is scarce, control the LED traffic light to change and use the digital tube to display the countdown, and at the same time control the ISD4004 single-chip voice recording and playback circuit to play the pedestrian permission communication command; If a vehicle runs a red light, control the OV9655 camera module to take pictures of the vehicle information and store it in the database; The voice recording and playback circuit plays instructions to prohibit pedestrians from running red lights; the remote monitoring interface saves and collects evidence of violations by calling the SQL Server database, and calls Baidu Map API to realize the location marking of the traffic system and the statistics of traffic violations in various places, which is convenient for future systems maintain.

detailed description

The scheme of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

The system block diagram of a pedestrian crossing intelligent control scheme provided by the present invention is shown in Figure 1. The system includes STC12C4052AD single-chip microcomputer, YJ0411 ground induction coil type vehicle detector, HC-SR501 human body infrared sensor, OV9655 camera, voice recording and playback circuit, street crossing Request button, LED traffic light, digital tube, power module and remote monitoring interface.

The specific working process is as follows:

Under normal working conditions, the system is in normal operation. When a pedestrian presses the crossing button to send a crossing request, the STC12C4052AD single-chip microcomputer controls the YJ0411 ground induction coil vehicle detector to detect the current vehicle traffic situation. If there are fewer vehicles, the LED traffic lights are controlled to switch And control the digital tube to display the countdown, and then control the ISD4004 single-chip voice recording and playback circuit to play the pedestrian permission communication command. If the YJ0411 ground induction coil type vehicle detector detects that there is a vehicle running a red light, it will control the OV9655 camera module to take pictures of the vehicle information and then transmit it to the host computer database for storage. If the HC-SR501 human body infrared sensor detects that a pedestrian does not follow the instruction to cross the street and runs the red light, the STC12C4052AD single-chip microcomputer will play instructions through the ISD4004 single-chip voice recording and playback circuit to prohibit the pedestrian from running the red light. The remote monitoring interface saves and obtains evidence of violations by calling the SQL Server database, and calls the Baidu map API to realize the location marking of the intelligent transportation system and the statistics of traffic violations in various places.

The intelligent control scheme for pedestrian crossing in the present invention has been described in detail above, but the specific implementation form of the present invention is not limited thereto. For those skilled in the technical field of the present invention, various obvious changes made to the method of the present invention without departing from the spirit of the method and the scope of the claims are within the protection scope of the present invention.
