Description

A system for informing crowdedness of subway}

The present invention relates to a subway congestion notification system.

The subway is a railway built with tunnels in the ground to ease traffic congestion and to operate at high speeds in large cities. The subway is one of the most used means of transportation by people nowadays, and is used by millions of people in large cities. The subway moves along a predetermined line and stops passengers at predetermined times at a plurality of subway stations formed in the line.

The subway is formed in a structure in which a plurality of passenger cars are connected to each other, and a space for accommodating passengers is formed inside the passenger car.

A plurality of entrance doors are installed in the carriage, and are automatically opened and closed at the stop of the subway station. Passengers wait for the subway at the platform of the subway station, and when the door is opened after the carriage arrives at a predetermined position, the passenger gets on the carriage. In addition, a plurality of chairs for seating passengers and handles for standing passengers are provided in the passenger car.

However, there is a limit to the number of cars that can be connected when the subway is running. Therefore, while the number of passengers in the subway increases rapidly during the time when there are many passengers, such as commute time, the number of passengers in the subway is limited, so the number of passengers in one passenger car increases.

Even if the number of passengers increases, there is no problem up to a certain number of passengers. However, when more passengers ride in one passenger car, the distance between the passengers becomes narrower, thereby increasing the discomfort of the passengers and causing a safety accident.

In particular, due to a phenomenon in which passengers are crowded with passengers stopped near the entrance stairs of a platform, a large number of passengers repeatedly ride only in a specific passenger vehicle, so that the load on the passenger vehicle increases and wear is biased. .

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a subway congestion notification system that can evenly distribute passengers in the passenger cars of the subway.

In addition, an object of the present invention is to provide a subway congestion degree notification system that can prevent a safety accident by lowering the congestion degree of the passenger car.

In addition, it is an object of the present invention to provide a subway congestion notification system that can increase the satisfaction of passengers using the subway.

In addition, an object of the present invention is to provide a subway congestion notification system that can prevent a phenomenon in which wear is concentrated due to concentration of passengers in a specific passenger car.

Subway congestion notification system according to an embodiment of the present invention for achieving the above object, the load sensor is provided in each of the plurality of passenger cars of the subway, the load sensor for detecting the load; A congestion calculation unit configured to calculate a congestion degree of the vehicle from the sensed load; A display device provided at a platform of a subway station to which the subway enters and displaying operation information of the subway; And a congestion degree display processor for displaying the congestion degree calculated by the congestion degree calculator on the display device.

According to the subway congestion notification system according to an embodiment of the present invention as described above, by informing the passengers waiting for boarding at the platform of the next station to inform the congestion of the passengers to arrive, induce the customer to actively board the less crowded cars Therefore, there is an advantage that evenly distributed passengers in the carriage.

In addition, by preventing the concentration of passengers in a particular vehicle to increase congestion, the risk of a safety accident is eliminated, and the passengers can feel comfortable.

In addition, by preventing a load from being concentrated in a specific carriage to induce a similar amount of wear for each carriage, there is an advantage that the maintenance cost is reduced.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a view showing the configuration of a subway congestion notification system according to a first embodiment of the present invention, Figure 2 is a view showing the information displayed on the display device of FIG.

Hereinafter, in order to explain the idea of the present invention will be described by taking an example of the subway to which four carriages are connected. However, the spirit of the present invention is not limited thereto, and it is understood that the present invention is applicable to all subways to which a plurality of passenger cars are connected.

1 and 2, the subway 10 to which the subway congestion notification system according to the first embodiment of the present invention is applied includes four carriages 11, 12, 13, and 14, and the first subway station 51. ), And moves along the rail to the second subway station 52.

The carriages 11, 12, 13, and 14 are connected to each other, and a driving part is provided below each carriage so that the carriages can move along the rails. Referring to the first carriage 11 as an example, a plurality of the driving portion is provided below the first carriage 11, the driving portion is a wheel 113 for rolling over the rail and the wheel 113 is mounted Frame 111 is included. The frame 111 may be provided with a motor / brake for driving / braking the wheel 113. In addition, a support part 115 supporting the load of the first carriage 11 is formed on the upper side of the frame 111. That is, the load of the first carriage 11 is sequentially transmitted to the frame 111 and the wheel 113 through the support 115.

In addition, one side of the support 115 is provided with a load sensor 119 for detecting the load of the first carriage 11 applied to the support 115. In this case, a plurality of load sensors 119 may be provided to calculate an accurate load of the first carriage 11, and an average value thereof may be used as a load of the first carriage 11. In addition, the load sensor 119 is connected to the congestion calculator 30 to be described later, and transmits the detected load value to the congestion calculator 30.

The above configuration is applied in the same manner to the second carriage 12, the third carriage 13, and the fourth carriage 14.

In addition, the subway 10 is provided with a congestion calculator 30 that calculates a congestion degree of the cars 11, 12, 13, and 14. Here, the congestion calculation unit 30 is provided to the subway 10 is just an example, and may be provided not only to the subway but also to each subway station or an institution in charge of the subway. That is, the idea of the present invention is related to calculating the congestion degree of the above-mentioned differences 11, 12, 13, and 14 itself.

In detail, the congestion calculating unit 30 calculates the congestion degree of the corresponding vehicle by calculating the number of passengers aboard from the load of the vehicle. Here, the congestion degree may be defined to the extent that a passenger is boarded in each carriage. For example, if the number of passengers when all of the chairs and handles provided in the car are occupied is A and the number of passengers currently in the car is B, the congestion degree may be defined by the following equation (where A The name can be seen as a garden of the carriage, the A name is just an example, the garden may be defined in various ways depending on the environment in which the subway (10) is provided.).

Therefore, in order to calculate the degree of congestion, it is necessary to know the number of passengers currently aboard.

The number of passengers currently in the carriage can be calculated by the following equation.

In detail, the load of the current passenger car is a value detected by the load sensor 119, and the load of an empty passenger car is a load value of the passenger car when the number of occupants is zero. That is, the value obtained by subtracting the load of the empty passenger car from the load of the current passenger car can be regarded as the load introduced into the passenger accommodation space inside the passenger car. Therefore, dividing this by the average load per passenger, it is possible to know the number of passengers currently on board. Here, the average load per passenger may be used to add the average weight of the weight to the average weight of the subway user. In addition, the congestion calculation unit 30 calculates a congestion degree by substituting the current number of passengers found in the equation (1).

In order to calculate the degree of congestion, the congestion calculator 30 controls the memory 33 in which necessary information is stored and the load sensor 119.

In detail, the memory 33 may store data such as the number of passengers when the chair and the handle are occupied, the load of the empty car, the average load per passenger, and the like. In addition, the congestion calculation unit 30 transmits a load sensing command to the load sensor 119 to sense the load of the first carriage 11. That is, the congestion calculator 30 calculates a congestion degree using the data sensed by the load sensor 119 and the data stored in the memory 33.

Here, the congestion calculator 30 may continuously detect the load of the first carriage 11 or may detect it intermittently.

In addition, the congestion calculation unit 30 may calculate the congestion degree of the second carriage 12, the third carriage 13, and the fourth carriage 14 in the same manner.

The congestion calculation unit 30 calculates a congestion degree while moving from the first subway station 51 to the second subway station 52, and provides the result to the second subway station 52, the next stop. The congestion is transmitted to the display processing unit 40. That is, the congestion degree information transmitted to the underground railway station is the congestion degree information of the subway starting from the previous subway station and entering the subway station.

The congestion degree display processing unit 40 is provided for each of the subway stations 51 and 52, and based on the information transmitted from the congestion degree calculating unit 30, the display device 44 or 45 is used to display the subway station 51, 52. The passengers waiting for boarding at the platform in) tells the crowdedness of the subway that is entering.

The display device 45 may be installed in a plurality of platforms in the subway stations 51 and 52, and may be provided in a structure that is suspended from the ceiling so that all passengers can see even if the platforms are crowded. As the display device 45, an electronic display board or an LCD may be used. In addition, various visual expression means capable of displaying patterns, symbols, and the like may be used as the display device 45.

The display device 45 has a character unit 451 for displaying the operation information of the subway (particularly, the subway enters the platform where the display device 45 is installed), and a pattern portion 453 for displaying the congestion degree of the passenger car. Included.

The character unit 451 may display a current location, a destination, a scheduled arrival time, and the like of the subway in operation, and display information by text or symbol.

The pattern portion 453 may include a figure 453a having a carriage shape and a congestion degree display portion 453b filled in the figure 453a to be easily recognized by the user. In detail, the figure 453a may be formed in a form in which a plurality of figures 453a are connected, and one figure 453a may express information about one or more cars.

The congestion display unit 453b may be painted with a different color according to the congestion degree of the vehicle corresponding to the figure 453a.

In detail, a memory 43 may be connected to the congestion display processor 40, and different colors may be stored in the memory 43 according to congestion. In addition, the congestion display processor 40 compares the congestion degree of each vehicle transmitted from the congestion calculator 30 with a value stored in the memory 43 and expresses a color corresponding to the congestion display unit 453b. do.

For example, the memory 43 may store data obtained by dividing the congestion into several groups so that colors of low brightness correspond to the congestion as the size increases. For example, referring to FIG. 2, the congestion display unit 453b of the third-placed car is the darkest, which means that the third-placed car has the highest congestion.

As another example of expressing congestion on the congestion display unit 453b, the congestion degree may be represented by a difference in the area where the figure 453a is filled even when the same color is used. In this case, when all of the figures 453a are filled, the corresponding carriage may be determined to be full.

As described above, since the congestion degree of the subway car to be arrived on the display device 45 is displayed, the passenger waiting for boarding in the platform can naturally move to board the car with small congestion. Therefore, the passengers can be evenly distributed in the carriage.

In addition, it is possible to reduce the risk of safety accidents by preventing the concentration of passengers in a particular vehicle and increasing congestion.

In addition, since the passengers are evenly distributed, it is possible to solve the discomfort caused by physical contact with the surrounding passengers, and the emission of carbon dioxide can be reduced, thereby providing a comfortable air.

In addition, by preventing the load from concentrating on a specific passenger, maintenance costs can be reduced because a similar amount of wear occurs for each passenger vehicle.

The congestion calculator 30 may be integrally formed with the congestion display processor 40. That is, the subway 10 senses only the load of each passenger car using the load sensor 119, and the information is integrated into the processing unit (the congestion calculation unit 30 and the congestion display processing unit 40) of the next subway station. The controller may calculate the congestion degree and display it directly on the display device 45.

Hereinafter, a subway congestion notification system according to a second embodiment of the present invention will be described with reference to the drawings. However, since the second embodiment has a difference in the arrangement of the load sensor and the information expressed by the display device as compared with the first embodiment, the difference will be mainly described.

3 and 4, the subway congestion notification system according to the second exemplary embodiment of the present disclosure may inform passengers waiting for boarding in a platform to stop next, the number of empty seats in a passenger car.

In detail, the second carriage 12 is provided with a door 121 and a plurality of chairs 123 on which passengers can sit. In addition, a chair load sensor 125 is provided at each lower side of the chair 123. When a passenger sits on the chair 123, the value applied to the chair load sensor 125 changes.

The change in the load sensed by the chair load sensor 125 is transmitted to the congestion calculator 30. Then, the congestion calculator 30 may determine whether the passenger is seated on the chair 123 according to the presence or absence of a weight change, and as a result, determine how many empty seats remain in the second carriage 12. can do. In this case, the total number of chairs in the carriage may be stored in the memory 33.

The congestion calculating unit 30 transmits the number of empty seats in the passenger car to the congestion display processing unit 40 of the subway station to be stopped next. The congestion display processor 40 displays the information transmitted from the congestion calculator 30 on the display device 45.

As in the first embodiment, the display device 45 is provided with a character part 455 and a pattern part 457, and the character part 455 can recognize that an empty seat is displayed. The phrase is displayed. For example, the phrase “next train empty seat” may be displayed on the character unit 455. In addition, the figure 457a in the shape of a carriage may be displayed on the pattern portion 457 and the number of empty seats of the carriage corresponding to the inside of the figure 457a may be displayed.

A passenger waiting at the next stop can see the display device 45 and can board a passenger car having a large number of empty seats, so that the subway 10 can be used more conveniently and comfortably.

In addition, if the number of empty seats is expressed simultaneously or sequentially with the congestion degree of the first embodiment, it is possible to maximize the comfort of the passengers.

Hereinafter, a subway congestion notification system according to a third embodiment of the present invention will be described with reference to the drawings. However, since the third embodiment has a difference in the arrangement of the load sensor and the information expressed by the display device as compared with the first embodiment, the description will be mainly focused on the difference, and the same parts will be described with reference to the description and reference numerals of the first embodiment. Use it.

5 and 6, the subway congestion notification system according to the third exemplary embodiment of the present disclosure may inform passengers waiting for boarding at a platform to be next stopped.

In detail, a plurality of doors 131 are spaced apart at predetermined intervals on both sides of the third carriage 13, and a plurality of chairs 133 are provided between the doors 131 to allow passengers to sit. . In addition, a handle may be further provided around the chair 133 to support standing passengers. In addition, an entrance load sensor 135 for detecting a change in load is provided on the bottom surface of the third carriage 13 around the door 131. The doorway load sensor 135 may be installed at least in an area including the front part of the door 131, and may be installed between the doors 131 facing each other. In addition, the doorway load sensor 135 may be connected to the plate-shaped member forming the bottom surface of the third carriage 13 to detect the load change of a large area.

In general, when passengers get close to the station where they get off, the passengers move near the door 131 and prepare to get off. That is, until the subway 10 stops at the subway station and immediately before the door 131 is opened, the passengers to get off are gathered in the A area. Thus, the load applied to the doorway load sensor 135 is increased.

The congestion calculation unit 30 may calculate the estimated getting off number from the change amount of the load detected by the doorway load sensor 135. In detail, when the change amount of the load detected by the doorway load sensor 135 is divided by the average load per passenger, it is possible to know how many passengers entered the area A.

In addition, the congestion calculation unit 30 may control the entrance load sensor 135 to continuously detect the change in the load of the area A, thereby calculating the actual estimated getting off number. In detail, when the load change is sensed in real time, the number of people exiting the area A and the number of people entering the area A can be known. For example, when the load in the area A is reduced to a degree corresponding to the average load per passenger, it is determined that the passenger has exited, and when it is increased to a degree corresponding to the average load per passenger, the passenger may be determined to be introduced. have. Therefore, it is possible to determine the total number of inflows into the area A.

It is preferable to calculate the estimated number of passengers as described above after a few seconds have elapsed since the subway 10, which can be regarded as seated by the passenger, departs from the subway station.

On the other hand, the congestion calculation unit 30 transmits the estimated getting off number to the congestion display processing unit 40 of the next subway station to stop. The congestion display processor 40 displays the information transmitted from the congestion calculator 30 on the display device 45.

As shown in the first embodiment, the display device 45 is provided with a character part 458 and a pattern part 459, and the character part 458 can recognize that waiting passengers can display the expected number of getting off. Is displayed. For example, the phrase 'expected get off number' may be displayed on the character unit 458. As shown in the first embodiment, the figure 459a having a carriage shape may be displayed on the pattern portion 459, and the estimated number of getting off passengers corresponding to the inside of the figure 459a may be displayed.

In addition, the expected getting off personnel may be displayed simultaneously or sequentially with the congestion degree of the first embodiment. Therefore, a passenger waiting at the next stop may see the display device 45, even if the crowd is somewhat high in congestion, and if the expected number of unloaded passengers is large, the passenger may board the vehicle as it is without moving to another passenger's boarding position.

The scope of the present invention is not limited to the above-described embodiments, and the embodiments may be changed, added, or deleted within the scope of the spirit of the present invention.
