Receiving the signal, the data demodulator 90 demodulates the received data.

When the selection signal in which the broadcasting item is selected from the user operator 10 and the section selection signal in which the receiving side history 110 or the section is selected are input to the central control controller 50, the central control controller 50 may select the broadcasting item selection signal. The voice message is read from the memory 40, and the data including the history designation code of the reception station 110 is read according to the section selection signal and output to the data matching unit 60. .

Here, the impedance of the output terminal of the central control unit 50 is, for example, 6Ω, the output terminal impedance of the data matching unit 60 is 200Ω, so the data matching unit 60 matches the impedance of the data to the output terminal. .

The matched data is input to the converter 70 and converted. That is, for example, the RS232 signal, which is a short-range signal, is converted into an RS422 signal according to the transmission distance and output to the transmitting means 81. At this time, the voice message through the data matching unit 60 is directly input to the transmission means 81 without passing through the converter 70.

Therefore, the transmission means 81 transmits the data and voice message to the reception systems 110, 120, 130, 140 of all subway sections.

In addition, when a user's direct input selection signal is applied through the user manipulation unit 10, the central control controller 50 receives the voice message input through the voice input unit 30 through the data matching unit 60.

The receiving means 82 receives the voice message and the data and outputs the data to the demodulation means 114. The demodulating means 114 outputs the data input from the receiving means 82 to the control means 115. And demodulate it into a signal recognizable at Therefore, the control means 115 checks the history designation code included in the data inputted from the demodulation means 114, checks whether the corresponding code matches its own code, and controls the amplification means 113 if it does not match. Blocking the output of the message, if the match is controlled by the amplifying means 113 to amplify the voice message. Thus, the amplified voice message is broadcasted through the speaker 111 in the history 110. Here, the speaker is installed in each of the uphill platform, downline platform, waiting room, etc. in the history, the amplifying means 113 selectively outputs and blocks a voice message to a plurality of speakers 111 installed in each area.

In addition, the control means 115 transmits an acknowledgment signal to the central control broadcasting system 100 through the transmission means 116, when the history designation code is matched with its own designation code. It transmits with error status and error items of the corresponding receiving system.

That is, for example, the control means 115 transmits a total of 12 bytes of the acknowledgment signal, of which 1 byte includes a history designation code, 4 bytes includes an error item, and the remaining bytes include a reception date. Send the data.

Accordingly, the central control controller 50 checks whether the history 110 is in error as described above, and displays it on the display 20.

6 is a flowchart illustrating a central control broadcasting method of subway stations according to the present invention.

Referring to FIG. 6, the central control broadcasting method of the subway station 110 according to the present invention divides the entire subway section into a plurality of sections including at least one history 110 and selects each section, and a corresponding voice message. And reading the data including the history designation code and transmitting the same (S100).

And an error acknowledgment step (S300) for determining whether there is an error or an error item of the history 110 through the acknowledgment signal transmitted in the acknowledgment transmission step (S200) and displaying it.

Here, in addition to the error checking step (S300) through the acknowledgment signal of the voice message transmitted from the central control broadcasting system 100 as described above in the error checking step (S300), the central control broadcasting system 100 is constant Transmitting an error acknowledgment signal to the entire history 110 every time, and confirming the error through the acknowledgment signal received from the history 110, which will be described later.

7 is a flowchart illustrating a voice message transmission step, and FIG. 8 is a display screen of the central control broadcasting according to the present invention.

7 and 8, first, the central control controller 50 determines whether a selection signal of a broadcast item is input through the user operator 10 (S101 and S102). Accordingly, when the user selects the automatic guide broadcast item or the selection signal of the selected broadcast item, the user reads the voice message of the corresponding item stored in the memory 40.

Here, the automatic broadcast item includes items of train delay, fire accident, poison gas spray, and test broadcast displayed on the center left of FIG. 8, and the selected broadcast item is train delay, poison gas spray, fire displayed on the center right of FIG. 8. Includes accident and test broadcast items.

That is, both of them include the same item, but the automatic broadcasting item is broadcasted in the entire history 110 without distinction between the up line, the down line, and the waiting room by clicking the input terminal for each section formed at the bottom, and the selected broadcasting item is the train delay. And broadcasts of poison gas spraying or the like according to regions within the history 110. That is, by selecting only the ascending platform or descending platform, the waiting room of the station 110, the voice message of the corresponding item is broadcasted only to the corresponding area.

Therefore, if the automatic broadcasting item is selected in the broadcasting item selecting step (S102) (S103), the central control controller 50 reads the voice message of the selected broadcasting item (S106), and then selects the corresponding section according to the inputted section selection signal. (S107), the data including the history designation code in the corresponding section and the broadcast output control code in the entire history 110 is read (S108).

Alternatively, when the selected broadcasting item is selected (S104), the central control controller 50 checks the detailed selection parameters (S105), reads the corresponding voice message (S106), and then checks the corresponding section to the input section selection signal. (S107), the data including the history designation code in the corresponding section and the broadcast area setting code in the history 110 is read (S108).

The central control unit 50 outputs the read voice message and data to the data matching unit 60, and the data matching unit 60 matches the impedances of the input terminal and the output terminal to convert the data into the converter 70 and the voice message. Is output to the transmitting means 81 (S109). Therefore, the converter 70 converts the input data and outputs the data to the transmitting means 81 (S110), so that the transmitting means 81 transmits the data and the voice message to the entire history 110 (S111).

Alternatively, when the user directly selects the input in the above-described broadcast item selection step (S102), the central control controller 50 checks the reception history 110 through the selection signal for each section to check the data including the corresponding history specification code. Read (S107, S108), and transmits the voice message and the data input through the voice input unit 30 to the entire history 110 through the data matching step (S109) and converting step (S110) as described above. (S111).

And as described above, the voice message transmission step (S111) transmits the voice message and data to the entire history 110, but this is only in the history 110 as the history designation code is confirmed in the receiving system in the history (110) In the history 110, which is broadcast and not designated, the history designation code does not match, so that the output of the received voice message is blocked. This will be described in detail in the following receiving step.

9 is a flowchart illustrating a receiving step.

Referring to FIG. 9, when the voice message and data are received from the central control broadcasting system 100 (S201), the receiving means 112 outputs the data to the demodulation means 114, and the demodulation means 114. Demodulates the data so that it can be recognized by the control means 115 and outputs the data to the control means 115 (S202).

Therefore, the control means 115 checks the history designation code included in the input data and determines whether it matches the own code (S203). As a result of the determination, if the received code and the own code do not match, the amplifying unit 113 is controlled to block the output of the voice message.

Alternatively, when the reception code and the self code match in step S203, the control unit 115 confirms the match of the code and checks the broadcast area setting code included in the reception data (S204). That is, if the automatic broadcasting item is selected in the transmitting step (S102) and the corresponding data is included in the received data, the control means 115 controls the amplifying means 113 to amplify the received voice message. The voice message is output in the entire history 110 through the speaker (S204, S205).

Alternatively, when the selected broadcast item is selected in the transmitting step S102 and a broadcast area setting code including a command for selectively outputting a voice message in the history 110 is included in the data, the control unit 115 determines this. After confirming and controlling the amplifying means 113, the voice message is selectively output to a corresponding area, for example, an uphill platform or a downhill platform, a waiting room, and the like.

10 is a flowchart showing an error checking step.

Referring to FIG. 10, the central control controller 50 determines whether an acknowledgment signal is received from the history 110 after transmitting the voice message and data as described in the transmitting step S111 (S302). .

That is, the control means 115 of the reception system 110 receives the data and the voice message, and if the reception code and the self code match, the control unit 115 transmits an acknowledgment signal to the central control broadcasting system 100.

Preferably, the control means 115 checks the error items for the amplification of the voice message, the demodulation of the data, the voice output, and the failure of the speaker 111 for each region in each history 110. This is included in the acknowledgment signal and transmitted.

Therefore, the central control controller 50 checks the received acknowledgment signal to determine whether an error of the receiving system in the history 110 is detected (S304), and if an error occurs in the history 110, the error item is determined. The controller 20 checks and controls the display 20 to display it on the display 20 (S305 and S306). If an error does not occur in the history 110 as a result of the determination, the display 20 is controlled to display the reception completion (S307).

Alternatively, if the corresponding acknowledgment signal is not received even after a predetermined time elapses in the acknowledgment signal receiving step (S302), the central control controller 50 determines that an entire item of the receiving system of the history 110 has an error. The display 20 is controlled to display it (S303).

FIG. 11 is a flowchart illustrating still another example of an error checking step. Even if the voice message is not transmitted in addition to the error checking step occurring after the voice message and data transmission step in the corresponding history of FIG. How to check. .

Referring to FIG. 11, the central control controller 50 waits for a predetermined time and then reads a control code stored in the memory 40 when a predetermined time elapses (S311 and S312). Here, the control code includes a history designation code and an error check item code for each history 110.

The central control unit 50 outputs the read data to the data matching unit 60, and the data matching unit 60 matches the impedance of the applied data to the output side impedance and outputs the impedance to the converter 70. .

Therefore, the converter 70 converts the applied data into a signal having a transmission distance extended and outputs it to the transmitting means 81 (S314), and the transmitting means 81 transmits it to the entire history 110 (S315). ).

Thereafter, the central control controller 50 determines whether an acknowledgment signal is received from the history 110 (S316), and if the acknowledgment signal is not received from the history 110 for a predetermined time, the display 20 is displayed. Control to display the error of the entire item of the history (110) (S320).

Alternatively, when an acknowledgment signal is received from the corresponding history 110 in the acknowledgment step (S316), the error item code included in the acknowledgment signal is checked to determine whether an error occurs in the corresponding history 110 (S317). ).

As a result of confirmation, if an error occurs in the corresponding history 110, the central control controller 50 checks the corresponding error item and controls the display 20 to display error items for the corresponding history 110 (S318, S319).

As described above, the central control broadcasting system 100 according to the present invention outputs a voice message by selecting any one of the entire section, section, and individual history 110, and also selects the user to directly input the stored voice message or the stored voice message. Is possible by

As described above, the central control broadcasting system and method of the subway station according to the present invention store voice messages that are frequently used, select the whole section, the individual section and the individual station selectively, and guide the broadcast area in the corresponding history. By conducting the broadcasting, the situation can be quickly responded to, thus improving the convenience and safety of the passengers, and the system can be easily managed by checking the abnormality of the system from time to time.
