Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic broadcast system for announcing the arrival and departure of moving objects such as vehicles in transportation facilities such as railways.

[Conventional technology]

An example of a railway station guidance broadcast system will be explained below.

Conventional guidance announcement systems rely on train characteristics (in this case,
Broadcast text was determined based on destination, train type, number of cars, etc., and was broadcast at the timing of train arrival and departure.

Known examples include JP-A-53-65004 and JP-A-53-107010.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, when a train is delayed, passengers concentrate on the delayed train, which further increases the delay. At this time, delays can be prevented by shortening the stopping time and allowing the train to depart.

However, there was a problem in that the train could not depart until the guidance broadcast had finished broadcasting a certain number of messages determined by the characteristics of the train.

An object of the present invention is to shorten the stopping time of a delayed train when a train is delayed, thereby preventing the delay from increasing and recovering from the delay.

[Means to solve the problem]

The above purpose is to broadcast texts selected according to the characteristics of the train.
This is achieved by shortening the broadcast time by changing the content of the broadcast text depending on the time period in which the delay occurs and the amount of delay.

[Effect]

The information broadcast for a delayed train is shortened to the minimum length of broadcast text necessary for passenger guidance, depending on the time period of the delay and the amount of delay.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. S1
S from the station. At each station, an automatic broadcast system is broadcasting information according to the condition of the train.

The broadcasting device 1 at each station grasps the train operation status based on the train position information taken in from the process input device 3, and uses pre-stored timetable information to determine the train characteristics (destination, train type, number of cars, etc.). ), so if a train is approaching a station, it will broadcast an arrival notice (also called an approach broadcast).
When the train arrives at the station, an arrival announcement (transfer information announcement, etc.) is broadcast, and when the train leaves the station, a departure announcement and a departure bell are broadcast on the platform. Although these broadcasts are diverse, the formats (patterns) of sentences can be classified into several types and can be converted into sentences by simply replacing the constituent words. Necessary words and phrases are taken out to the broadcasting device 1, and an audio signal converted into an analog signal is outputted to the speaker 4.

On the other hand, the broadcasting device 1 can also determine the train delay status based on the train operation status and timetable information.

Time chart 1 from when the train arrives at the station until it departs
・is shown in Figure 5.

If the train is delayed, once the train arrives at the station, the processing time required during the stop (the time required to control the departure signal,
Departure broadcast time 9 Departure platform broadcast time.

The expected departure time will be moved forward after securing the door closing time, etc.). In other words, delay recovery is achieved by reducing the stopping time of delayed trains to the minimum required stopping time.

However, during rush hours, passengers are concentrated on delayed trains, so it takes time to close the doors after the information announcement ends and the train departs, making it difficult to depart. This further increases the delay.

In the present invention, as shown in FIG. 2 (a), (b), and (c), the departure broadcast sentence is divided into patterns of regular broadcast, shortened broadcast, and no broadcast according to the train delay situation, so that delayed trains can be The stoppage time was shortened in an effort to recover from delays.

FIG. 3 shows the selection pattern of the departure broadcast text depending on the train running time zone and the amount of delay.

During the morning rush hour when there are many passengers getting on and off, if the delay is longer than a certain amount of time, pattern (c) is selected in which the departure announcement is not made and only the departure platform is used to minimize the stopping time. During daytime hours, there are few passengers getting on and off the train even if there is some delay, so the departure broadcast is set to the normal broadcast pattern (a).

FIG. 4 shows the broadcast text content of each pattern (a), (b), and (0).

FIG. 6 is a flowchart 1- for determining a starting broadcast pattern.

〔Effect of the invention〕

According to the present invention, the stopping time of a delayed train can be adjusted to be shortened, so that delay spread can be prevented and recovery can be performed.

Claims (1)

[Claims] 1. In the guidance broadcast in the operation management system of transportation facilities such as railways, when a train is delayed, in order to shorten the stopping time and recover from the delay, the time period of the delay occurrence, and , an automatic broadcast system characterized in that the content of the guidance broadcast can be changed depending on the amount of delay and the broadcast time can be adjusted.
