Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a system for simultaneously or selectively broadcasting from a central location to a plurality of locations. The present invention relates to a broadcasting system in which a medium is installed in each terminal device and code signals for identifying the messages are instructed from the center.

[Conventional technology]

With the development of communication networks, in the case of railways, for example, if a vehicle accident, overhead wire or track accident, or railroad crossing accident occurs, the driver of the vehicle will immediately contact the central operation command center using the dedicated railway communication network. You can report it. Upon receiving this report, the central operation command center can grasp the state of the accident and instruct the following trains to stop operation, or the stations on the relevant route to stop train operation. In addition to preventing train accidents, it is also possible to notify railway users of the occurrence of accidents through station announcements.

In addition, a management system for automatic cash withdrawal machines in financial institutions such as banks, in which a large number of automatic cash withdrawal machines are placed in various locations, and a central management department such as the head office keeps track of the balance and denomination in each automatic cash withdrawal machine. If a user is unable to make a withdrawal due to an online malfunction or a lack of funds or denominations in a certain automated cash withdrawal machine, we will notify the user immediately and ask them to wait for a while.
A communication system has been adopted that notifies the department to which the automatic cash withdrawal machine belongs and prompts them to take appropriate action in response to online failures and to replenish banknotes.

[Problem to be solved by the invention]

However, in the former case, even when the central operation command center is communicating with each station, there is a possibility that there will be a message from the accident vehicle, a following train, or about an accident occurring at another location, so it is difficult to contact each station. Communication must be done quickly and with accurate information. In the latter case, there is a possibility that a similar accident may occur at another location even while the announcement is being made to the users of the automatic cash withdrawal machine, and it is necessary to respond quickly. .

Looking at the types of these messages, in the case of the former, the types of messages that are normally communicated to the station in the event of an accident are limited, such as the type of accident, expected recovery, and return train information. In the latter case, the types of messages such as failure types and recovery prospects are further reduced.

Therefore, an object of the present invention is to install a storage medium storing a plurality of messages in each terminal device in advance, and transmit only a code signal that identifies a desired message from the center. Provided is a broadcasting system that extremely shortens the time required to transmit information to terminal equipment, and also uses a separate recording medium for each message, making it easy to change or replace messages. It is to be.

[Means to solve the problem]

The present invention provides a broadcasting system for selecting and broadcasting at least one of a plurality of different fixed forms of information from a central control unit to an arbitrary terminal device among terminal devices installed at a plurality of locations. A designation code for identifying each terminal device is set, each piece of fixed information is stored in a separate storage medium, each terminal device is loaded with these storage media in a similar manner, and each piece of fixed information is stored in a separate storage medium. Store them in each terminal device along with a message code that identifies them.
The central control unit transmits the message code and specification code of the fixed form information to be broadcast to each terminal device, and each terminal device, if the received specified code is applicable, transmits the corresponding fixed form information according to the message code. This system is characterized in that it is broadcast using synthesized sound.

〔Example〕

An embodiment of the present invention shown in the drawings will be described below. In this embodiment, a case will be explained in which each station is notified of an accident on a railway. First, the overall configuration will be explained with reference to FIG.

A central control unit 1 is installed in the central operation command unit, and one terminal device 2 . . . 6 is installed at each station, which are connected by a dedicated or communication line 7. Although this example uses connections between five stations as an example, it should be understood that this number is merely illustrative.

As shown in FIG. 2, the central control unit 1 includes a control unit 11 composed of a microcomputer, etc., and a storage unit 12 for primary storage of ROM such as control programs of the control unit 11 and broadcast data. , and a message code storage section 13 that stores various messages and codes for identifying the messages. The control unit 11 further includes a display unit 14 composed of a liquid crystal or CRT for displaying the transmitted message and a confirmation signal from the receiving side, and a display unit 14 for inputting the message code to be broadcast, additional information, etc. An input unit 15 is connected to the line 7 via an input/output port (hereinafter referred to as Ilo) for an interface.

The terminal equipment 2...6 installed at each station has a configuration as shown in FIG. That is, a control section 22 composed of a microcomputer or the like is connected to the line 7 via a power line 1021, a storage section 23 such as a ROM for storing control programs of the control section 22, and a message storage section 23 for storing various messages. A recording section 24, a display section 25 composed of a liquid crystal or CRT, etc. for displaying messages being broadcast, etc., into which messages to be broadcast only at that station, reception confirmation signals for messages from the central control section 1, etc. are input. It has an input section 26 and a timer section 27 for setting the time interval of message broadcasting. A speech synthesis section 28 that converts message information called from the message recording section 24 into synthesized speech is connected to the control section 22, and the output side of this speech synthesis section 28 is connected to a mixing section 29 and an amplification section 3.
1 to the speaker 32. A microphone terminal 33 is connected to the mixing section 29 via a microphone amplification section 34.

As shown in FIG. 4, the message recording section 24 includes an insertion slot 41 into which five memory cards 35...39 are inserted.
. . 45, a memory card reproducing device 46 is provided. The memory card playback device 46 is also provided with a setting dial 47 for manually setting the time of the timer section 27 independently of the terminal device. In this case, by using a RAM card for business cards or a writable RAM card that has recently become widespread, the memory card reproducing device 46 can be configured to be compact and does not take up much space.

Next, a more detailed explanation of each of these configurations will be given along with their operations. Each station has an identification code. On the other hand, the memory card 35 stores a fixed-form message simply stating that ``the train has stopped due to an accident,'' and the memory card 36 stores a message that says ``A ☆★ accident occurred near QO station around XX o'clock, and an accident is currently occurring.'' Assume that a fixed-format message to the effect of ``Processing is in progress, but there is no hope of recovery'' is stored. Also,
Memory card 37 contains ★★accident near Roo station.
A fixed form message is stored in the memory card 38 stating, "A ☆☆ accident occurred around XX o'clock near the room, and the accident is currently being handled, and operation will resume around ΔΔ o'clock." It is assumed that a fixed-format message to the effect of ``We are conducting a return trip to the station'' is stored, and that the memory card 39 stores messages that differ for each station, such as information on alternative transportation facilities. 00 in these messages
Alternatively, instructions are given by the input section 15 of the central control section 1 in accordance with the Loro station, the type of accident, and XX or ΔΔ time, depending on the state at that time. These memory cards 35...
・39 is an identification code, for example, memory card 35 is O
l, memory card 36 is 02, memory card 37 is 03
The memory card 35 is inserted into the insertion slot 41 of the memory card playback device 46, the memory card 36 into the insertion slot 42, the memory card 37 into the insertion slot 43, and so on.

Although not shown, the input unit 15 of the central control unit 1 includes a numeric keypad for inputting code signals for identifying stations, memory cards, etc., as well as the above-mentioned oo or Loro station and
It has a switch panel for inputting × or ΔΔ time. The switch panel displays various items,
Using a well-known switch panel that outputs data by touching the relevant area, it displays the station name, level crossing, type of accident such as a vehicle or overhead wire, and time, and then touches the relevant area with your finger. It consists of information in a format that allows input.

A railroad crossing accident occurred near station X from a train currently in operation.
Suppose that a message that the train has become inoperable is received via train radio to the central operation control department. If the central operation command center needs to stop all trains, it notifies all trains by radio, and also broadcasts a fixed message to each station stating that ``trains are stopped due to an accident.'' instruct them to do so. The structure of the transmission data at this time will be explained with reference to FIG.
By operating the numeric keypad 5, input the command code indicating that the message is for broadcasting as the header 52, and then input the memory card to be used, in this case the memory card 35.
A message code 53 for identifying the station; a station designation code 54 for indicating that all stations are to be symmetrical; and a broadcast format for instructing the broadcast format, such as whether the message will be broadcast repeatedly or multiple times at predetermined intervals. Enter code 55. Finally, by operating the transmission end key of the input unit 15, an end code 56 is generated, and these data are automatically transmitted.

These codes are converted into signals by the control unit 11 and sent to l10.
16 to each terminal device 2...6 via line 7. In each terminal device 2...6, these data signals are input from l1021 to the control unit 22, and the control unit 2
In step 2, the storage unit 23 determines from the header 52 that the message is for broadcast. Next, the control unit 22 determines the memory card to be used from the message code 53,
It is determined from the station designation code 54 whether the message designates the own station. If so, the message recording section 24 is instructed to reproduce the memory card 35, and it is determined from the broadcast format code 55 whether or not the corresponding message is to be repeatedly broadcast. The content of the message in the memory card 35 is displayed on the display section 25, and the message is converted into synthesized speech by the speech synthesis section 28, and the speech output is sent via the mixing section 29 and the amplification section 31 to the speaker 32 saying "Due to an accident, the train A voice saying "is stopped" is output to notify users on the platform, etc.

The operator of the terminal device inputs a code for confirming receipt from the input unit 26 along with a station designation code for identifying the station. The confirmation and station designation code is sent by the control unit 22 to l10.
21 via line 7 and line 1021 to the control unit 11 of the central control unit 1, and the control unit 11 instructs the display unit 14 to display which station has received the message. The operator of the control unit 1 can confirm which station has received the signal.

This reception confirmation response may be sent automatically after the control unit 22 determines that the data has been received without error.Data error determination is a well-known method such as when the receiving side sends a check pit back to the transmitting side. You can do it using this method.

In this case, if all stations respond all at once, a collision will occur in the transmission, so for example, a priority order of responses can be added to each station.

Transmission collisions can be avoided.

If this message is to be broadcast multiple times at predetermined time intervals, the broadcast format code 55 is input to the input unit 1 by a broadcast format code indicating that the message will be broadcast multiple times at predetermined time intervals.
5 and input the time interval as a code signal, the control unit 22 controls the timer unit 27 on each terminal device 2...6 side according to this time designation code.
and set the indicated time interval.

In this way, since the central control unit 1 only needs to instruct the type of message to be broadcast and the broadcast format using the code signal, the time required for transmission from the central control unit 1 to each terminal device 2... The time can be extremely shortened, and as a result, even if separate new information comes in at the time of a broadcast instruction, the operator of the central control unit 1 can immediately deal with it.

If the above-mentioned accident handling has been carried out and it is expected that the line will be reopened, a notice will be posted stating that ``A ☆☆ accident occurred near oo station around XX o'clock, the accident is currently being dealt with, and operation will resume around ΔΔ o'clock.'' The user instructs the user to broadcast a fixed message, and also inputs the station name, type of accident, time, etc. using the switch panel of the input unit 15. This allows the memory card 36
As shown in the transmission data in FIG. 6, the message code for identifying the station is followed by the station name code 57, the accident code 58, the accident time code 59, and the opening time code 60. 6. The control unit 22 of each terminal device 2...6 pulls out these codes from the storage unit 12, and fills in the corresponding blank areas of the message on the memory card 36 with the station, type of accident, time, etc., and creates a completed message. and sends it to the speech synthesis section 28. Therefore, information that cannot be quantified, such as location and time, can be encoded in advance by the tip, and detailed information can also be instructed to each terminal device 2...6 in a short time.

Further, regarding the stylized messages as described above, the message on the memory card 36 is more detailed information than the message on the memory card 35, and the message on the memory card 37 is more detailed information than the message on the memory card 36. You can prioritize from there. Therefore, it is set in advance that the order of priority is higher from the memory card 35 to the memory card 39. On the other hand, each terminal device 2
By providing the control unit 22 of 6 with a function of determining the priority order of codes representing memory cards, when a card code with a higher priority than already received message information is received, the already received message information is The information broadcast is immediately stopped, and message information is broadcast according to the newly received card code with a higher priority. In this case, the priority is memory card 35...3
9 or the insertion slot 41...45
It may be set in the position. With this, when more detailed information than the message being broadcast comes in, it is possible to immediately switch to broadcasting it.

This embodiment is equipped with a mixing section 29, a microphone terminal 33, and a microphone amplifying section 34, so that following the message on the designated memory card 35...39, detailed information obtained by that station is displayed. etc. can be added through a microphone.

Note that, as in the above embodiment, each memory card 35...
・Insert 39 into the insertion slot 41 of the memory card playback device 46...
・If it is specified that the messages are inserted into the insertion slots 41, .

Although the above-mentioned embodiment has been explained by taking railway broadcasting as an example, it can also be used for broadcasting failure information of automatic cash withdrawal machines at banks. In other words, a message broadcast when all automatic cash withdrawal machines are unable to withdraw money due to computer or online failure, or when only automatic cash withdrawal machines installed at some branches or outposts are unable to withdraw money. Since broadcast messages can be standardized, these messages are stored in the storage medium of a terminal device installed at the location where the automatic cash withdrawal machine is installed, and the corresponding message is broadcast based on the data transmitted from the central control center. Just do it. In this case, if the time when withdrawal will be possible is known,
All you have to do is enter the message code of the fixed-form message "What time will it be ready for use?" followed by the time code that specifies the time.

〔Effect of the invention〕

As described above, in the broadcasting system of the present invention, a designation code for identifying each terminal device is set, each piece of fixed information is stored in a separate storage medium, and each terminal device stores the The media are loaded in a similar manner, and the central control unit transmits the message code and specification code of the fixed form information to be broadcast to each terminal device, and each terminal device transmits the message code if the received specification code is applicable. Since the relevant fixed information is broadcast using synthesized sounds, the information can be transmitted from the central control unit to each terminal simply by specifying the code number. Information can be transmitted in an extremely short time, and since each piece of fixed information is stored in a separate storage medium, changing the message content can be done extremely easily by removing only the necessary storage medium. can be done. Furthermore, by prioritizing each of these fixed forms of information, it is possible to immediately switch to broadcasting the latest information in response to ever-changing information.
