Subway ticket evasion preventing system based on ultrasonic sensor and design method thereof

Abstract

The invention provides a subway ticket evasion preventing system based on an ultrasonic sensor and a design method of the subway ticket evasion preventing system. The system, on the basis of not changing existing equipment, is added with the ultrasonic sensor; pedestrian intervals and the number of pedestrians in an entrance channel are judged by acquiring distance data; with help of a card swiping number counter, the system can judge a ticket evasion phenomenon and open or close a gate. Through the ultrasonic sensor and a single chip program processing system, the system disclosed by the invention can automatically detect the ticket evasion phenomenon, overcome shortcomings of the existing equipment and transmit an alarm signal, therefore the accuracy and the intelligence degree of entrance automatic ticket checking are enhanced; the system disclosed by the invention saves human, physical and financial resources, prevents common occurring of the ticket evasion phenomenon and avoids unnecessary mistakes in a manual supervision process; through the ultrasonic sensor, the system solves the difficulty of manually supervising ticket evasion, and has advantages of being simple, efficient and accurate; the system well realizes electronization, intelligence and automation of a subway system, and can be commonly popularized on the basis of an existing subway system.

Description

technical field [0001] The invention relates to the technical field of subway intelligent ticket checking systems, in particular to a subway fare evasion prevention system based on an ultrasonic sensor and a design method thereof. Background technique [0002] With the progress of the times, the development of science and technology and the continuous improvement of people's lifestyles, people travel more and more frequently. In cities, rail transit, as an important and convenient way of travel, is favored by more and more people; at the same time, more and more cities are constantly developing and improving rail transit hubs. For example, Shanghai has just built No. 11 Line, Line 16, etc. are being built; Wuhan City is building a number of subway lines, etc. [0003] But it is precisely because more and more people choose to use rail transit as a way of travel, urban rail transit is facing great challenges. One of the most prominent is the phenomenon of fare evasion; taki...

[0003] But it is precisely because more and more people choose to use rail transit as a way of travel, urban rail transit is facing great challenges

One of the most prominent is the phenomenon of fare evasion; taking Shanghai as an example, the problem of Shanghai subway fare evasion is very serious. The average daily fare evasion of 10,000 people leads to an annual direct economic loss of more than 10 million yuan, leading to public disorder and bad social impact. The problem is that most cities still rely on human supervision. Due to the limited human supervision ability, the problem of fare evasion has not been improved.
