Problems solved by technology

[0003] The distribution of passengers in each subway car is uneven, resulting in some subway cars being crowded and some empty cars, resulting in a waste of public resources and affecting the travel experience of passengers. How to reasonably disperse and guide the number of people in each subway car , has become an urgent problem to be solved;
[0004] Chinese invention patent CN108944976A discloses a shunting device for compartment selection when taking the subway, and specifically discloses the following technical scheme, which uses the principle of infrared reflection to judge the degree of congestion in the compartment, so as to determine the number of people in the subway compartment, but When the infrared reflection device is blocked or partially blocked, it will lead to judgment errors, and the patent does not accurately judge the number of people in the car, which affects the accuracy of the judgment of the number of people in the subway car;

Abstract

The invention discloses a station real-time monitoring system based on a wireless sensor network, and belongs to the technical field of wireless sensing monitoring. The system comprises a data acquisition module and a data processing module. The data acquisition module performs real-time data acquisition on passenger positions of a subway station by using a wireless sensor network, and the data processing module is used for processing and calculating passenger position data acquired by the data acquisition module and wireless sensor coordinate value positioning data in the wireless sensor network; the number of passengers getting on and off the subway can be monitored through the installation positions of distance sensor sets, meanwhile, the number of passengers replacing the carriages canbe monitored, the number of people in each subway carriage can be monitored more accurately, and the number of people in each carriage can be displayed before the subway arrives at a station; therefore, passengers can select a carriage with a small number of passengers to take, and the passengers can take the subway freely.

Description

Technical field[0001]The invention relates to the technical field of wireless sensor monitoring, in particular to a station real-time monitoring system based on a wireless sensor network.Background technique[0002]With the continuous development of society and the continuous advancement of science and technology, the scale of my country's rail transit development is gradually expanding. Rail transit includes high-speed rail, trains, subways and other public transportation. When urban roads are crowded, normal traffic order and efficiency are affected. The development of subway rail transportation has greatly improved the problem of road congestion. However, with the continuous development of the subway, people also have various problems in the process of riding the subway:[0003]The uneven distribution of passengers in each car of the subway leads to congestion in some subway cars and empty space in some cars, which leads to a waste of public resources and affects the travel experienc...
