Abstract
Description
[Technical Field]
[0001] The present invention relates to a display system technology that visually notifies people in the vicinity in advance of the operation of a device such as an automatic door. [Background technology]
[0002] Devices with moving components, such as automatic doors, may pose a risk of contact with nearby people when they operate. It is desirable for nearby people to be notified in advance of the operation of such devices.
[0003] In particular, when passengers are guided and guided by voice output from loudspeakers, etc., this voice may be difficult for hearing-impaired people to understand. Also, for example, in stations, there are passengers who are talking or listening to music on music players, so voice warnings may not be conveyed. Therefore, it is necessary to warn passengers about the operation of devices in stations not only through hearing, but also through sight.
[0004] Patent Document 1 discloses a control system that receives control information wirelessly transmitted by a device, obtains from the control information information indicating the operating mode set by the device's user, and controls a movement control device based on this information. The movement control device controlled by this control system is, for example, a device that controls the movement of users, such as an automatic door or escalator. By being equipped with these components, this control system can detect when a user requiring special consideration approaches an automatic door (movement control device), and switch from normal mode to a classification mode that includes special consideration.
[0005] Patent Document 2 discloses an intelligent display / operation panel that recognizes input voice, and if the voice matches one of a plurality of voices corresponding to preset operation commands, outputs the matching operation command to a controller and causes the controller to execute the corresponding process. This intelligent display / operation panel allows screen switching processing to be performed by voice, so even an operator who is unfamiliar with the operation screen configuration can easily call up a desired screen.

[0007] However, the technology described in Patent Document 1 is only targeted at users who have wireless devices that transmit control information, and the technology described in Patent Document 2 does not perform processing unless voices corresponding to multiple preset operation commands are input.
[0008] One of the objects of the present invention is to display the voice of station staff as text information to passengers waiting in front of platform doors at a station. [Means for solving the problem]
[0009] In a first aspect, the present invention provides a display system that converts the speech of station staff into text information using voice recognition and displays the text information within the field of view of passengers waiting in front of platform doors at a station.
[0010] According to the display system of the first aspect, the voice of the station staff can be displayed as text information to passengers waiting in front of the platform doors at the station.
[0011] In the display system of the first aspect, a configuration in which text information is displayed on the platform screen doors or on a housing that houses the platform screen doors may be adopted as a second aspect.
[0012] According to the display system of the second aspect, the contents of the voice of the station staff can be visually conveyed to passengers waiting while looking at the housing that houses the platform doors.
[0013] In the display system of the second aspect, a configuration in which text information is displayed on a monitor provided in the housing may be adopted as a third aspect.
[0014] According to the display system of the third aspect, the monitor provided on the housing can visually convey to passengers the content of what the station staff is saying.
[0015] In the display system of the first aspect, a fourth aspect may be adopted in which station staff obtain information about the platform they are responsible for and display text information within the field of view of passengers waiting in front of the platform doors installed on that platform.
[0016] According to the fourth aspect of the display system, the contents of the voice of a station attendant can be shown to passengers waiting in front of the platform doors installed on each platform for which the station attendant is responsible.
[0017] In the display system of the fourth aspect, a fifth aspect may be adopted in which information about the platform platform assigned to a station staff member is obtained from a microphone used by the station staff member along with the station staff member's voice, and text information is displayed within the field of view of passengers waiting in front of the platform doors installed on that platform platform.
[0018] According to the display system of the fifth aspect, it is possible to obtain information about the platform number that the station staff member is responsible for along with the voice of the station staff member from the microphone used by the station staff member.
[0019] In the display system of the first aspect, a configuration may be adopted as a sixth aspect in which the urgency of the voice is determined, and if the urgency is higher than a predetermined level, text information is displayed.
[0020] According to the display system of the sixth aspect, if the urgency of the voice of the station staff is higher than a predetermined level, the contents of the voice can be shown to passengers. [Brief explanation of the drawings]

[0022] <Embodiment> <Display system configuration> Fig. 1 is a schematic diagram showing an example of the appearance of a display system 9. Fig. 2 is a block diagram showing the configuration of the display system 9. As shown in Fig. 1, the display system 9 includes an information processing device 1, a microphone 2, a platform door device 3, and a speaker 4.
[0023] The information processing device 1 includes a processor 11, a memory 12, and a communication unit 13. These are connected to each other via a bus so that they can communicate with each other.
[0024] The memory 12 includes a RAM (Random Access Memory), a ROM (Read Only Memory), a solid state drive, a hard disk drive, etc., and stores a computer program (hereinafter simply referred to as a program). The memory 12 is used when the processor 11 executes processing. The memory 12 shown in FIG. 1 also stores an urgency determination RB 121 and a track number DB 122.
[0025] The processor 11 controls the information processing device 1 by reading and executing a program from the memory 12. The processor 11 is, for example, a CPU (Central Processing Unit). The processor 11 may also be, for example, an FPGA (Field Programmable Gate Array) or may include an FPGA. The processor 11 may also have an ASIC (Application Specific Integrated Circuit) or other programmable logic device and perform control using these.
[0026] The communication unit 13 is a communication circuit that connects the information processing device 1 to other external devices, etc., by wire or wirelessly. This communication unit 13 communicably connects the information processing device 1 to the microphone 2, the platform door device 3, and the speaker 4 via a communication line such as an intranet or the Internet. The communication unit 13 may also communicably connect the information processing device 1 to various other external devices.
[0027] The microphone 2 is a device that collects the voice of the station staff, and includes a transmitting unit 23, an operating unit 24, and a sound collecting unit 25.
[0028] The sound collection unit 25 collects the voice of the station staff using a diaphragm or the like and supplies voice data representing this voice. The sound collection unit 25 may have a function of converting the collected analog voice data into digital data.
[0029] The transmitting unit 23 transmits the audio data supplied by the sound collecting unit 25 to the information processing device 1.
[0030] The operation unit 24 has buttons, switches, and other operators, and receives operations from station staff. The operation unit 24 receives various operations in addition to the operation to turn on the power of the microphone 2.
[0031] The platform door device 3 is installed on platform H at a station and is a device for protecting passengers from accidents such as contact with moving vehicles. The platform door device 3 has a housing 30, a processor 31, a memory 32, a communication unit 33, an operation unit 34, a display unit 35, platform doors 36, and indicator lights 37.
[0032] The memory 32 has a RAM, a ROM, a solid state drive, a hard disk drive, etc., and stores programs. The memory 32 is used when the processor 31 executes processing.
[0033] The processor 31 controls the platform door device 3 by reading and executing a program from the memory 32. The processor 31 is, for example, a CPU. The processor 31 may also be, for example, an FPGA or may include an FPGA. The processor 31 may also have an ASIC or other programmable logic device and perform control using these.
[0034] The communication unit 33 is a communication circuit that connects the platform door device 3 to other external devices, etc., by wire or wirelessly. The communication unit 33 connects the platform door device 3 to the information processing device 1 so that they can communicate with each other, for example, via a communication line such as an intranet or the Internet.
[0035] The operation unit 34 is equipped with operation elements such as operation buttons, a keyboard, and a touch panel for issuing various instructions, and receives operations and sends signals to the processor 31 according to the operation contents.
[0036] The display unit 35 is a monitor having a display screen such as a liquid crystal display. The display unit 35 shown in Fig. 1 is provided in an area on the surface of the housing 30 of the platform door device 3 such that the display screen is within the field of view of passengers waiting in front of the platform door 36.
[0037] The platform doors 36 are doors that open and close under the control of the processor 31. The platform doors 36 protrude from the housings 30 on both sides when blocking the passage from the platform H to the train, and are retracted into the housings 30 when opening this passage.
[0038] The indicator light 37 is provided in an area on the surface of the housing 30 that is within the field of view of passengers waiting in front of the platform doors 36. For example, the indicator light 37 is provided on the ceiling surface, which is the upper surface of the housing 30. The indicator light 37 has a light-emitting element, for example, an LED (light emitting diode), and is turned on under the control of the processor 31.
[0039] <Configuration of Urgency Determination RB> 3 is a diagram showing an example of the configuration of the urgency determination RB 121. The urgency determination RB 121 is a rule base that describes the contents of criteria, which are rules for determining each urgency level that indicates the degree of urgency. Examples of the contents of the criteria include that the volume of the station attendant's voice collected by the microphone 2 is equal to or greater than a threshold, or that the station attendant has performed a predetermined operation using the operation unit 24 of the microphone 2.
[0040] <Wire number DB configuration> 4 is a diagram showing an example of the configuration of the track number DB 122. A "track number" is a number assigned to each platform for trains entering a station. The track number DB 122 is a database that associates, for each track number ID indicating each track number, a station staff ID, which is identification information for the station staff in charge of the track number, with a microphone ID, which is identification information for the microphone 2 carried by the station staff.
[0041] <Functional configuration of information processing device> Fig. 5 is a diagram illustrating an example of the functional configuration of the information processing device 1. The processor 11 of the information processing device 1 reads and executes a program stored in the memory 12, thereby functioning as an acquisition unit 111, a determination unit 112, a conversion unit 113, an identification unit 114, and an instruction unit 115. Note that the communication unit 13 is not illustrated in Fig. 5.
[0042] The acquisition unit 111 acquires voice data indicating a voice from the microphone 2. If the voice data supplied by the microphone 2 is analog data, the acquisition unit 111 may convert this voice data into digital data. The voice data acquired by the acquisition unit 111 is supplied to the speaker 4 and output by the speaker 4, and is also supplied to the determination unit 112. The acquisition unit 111 shown in FIG. 5 acquires voice data from the microphone 2 and also acquires information for identifying the platform assigned to the station staff member who uttered the voice indicated by the voice data. For example, the acquisition unit 111 may acquire a station staff member ID from the microphone 2. The acquisition unit 111 may also acquire a platform ID directly from the microphone 2.
[0043] The determination unit 112 refers to the urgency determination RB 121 stored in the memory 12, and determines the urgency of the voice data acquired by the acquisition unit 111 based on the urgency determination RB 121.
[0044] The conversion unit 113 converts the voice data acquired by the acquisition unit 111 into text information by voice recognition. When the determination unit 112 determines that the urgency of the voice indicated by the voice data is higher than a predetermined level, the conversion unit 113 shown in Fig. 5 performs the conversion into text information by the voice recognition described above.
[0045] The identification unit 114 identifies the platform assigned to the station staff member who holds the microphone 2 from which the acquisition unit 111 acquired the voice data. The identification unit 114 shown in Fig. 5 refers to the platform DB 122 stored in the memory 12 based on the station staff member ID acquired by the acquisition unit 111, and identifies the platform ID associated with this station staff member ID.
[0046] The instruction unit 115 issues an instruction to the platform door device 3 installed at the track number identified by the identification unit 114 to display the character information obtained by the conversion unit 113.
[0047] <Operation of information processing device> Fig. 6 is a flow diagram showing an example of the flow of operations of the information processing device 1. As shown in Fig. 6, the processor 11 of the information processing device 1 acquires information indicating an operation by a station attendant from the microphone 2 (step S101), and also acquires voice data indicating a voice uttered by the station attendant (step S102).
[0048] The processor 11 determines the urgency of the voice based on the acquired voice data or information indicating the operation (step S103). Then, the processor 11 determines whether the urgency of the voice is equal to or greater than a predetermined level (step S104). When it is determined that the urgency of the voice is not equal to or greater than the predetermined level (step S104; NO), the processor 11 returns the process to step S101.
[0049] On the other hand, if it is determined that the urgency of the voice is equal to or higher than the predetermined level (step S104; YES), the processor 11 performs voice recognition processing on the acquired voice data and converts the content indicated by this voice data into text information (step S105).
[0050] The processor 11 also identifies the platform assigned to the station staff member who uttered the voice indicated by the acquired voice data (step S106), and instructs the platform door device 3 installed on the identified platform to display the converted text information (step S107).
[0051] As a result, the platform door device 3 displays text information obtained by converting the voice of the station staff through voice recognition on the display unit 35. In other words, the display system 9 is an example of a display system that converts the voice of the station staff into text information through voice recognition and displays this text information within the field of view of passengers waiting in front of the platform doors at the station.
[0052] 1 is a monitor provided in the housing 30. Therefore, this display system 9 is an example of a display system that displays text information converted from the voice of a station staff member by voice recognition on the monitor provided in the housing.
[0053] Furthermore, in step S106 described above, the processor 11 of the information processing device 1 identifies the platform for which the station attendant is responsible, and issues instructions to the platform door device 3 installed on the identified platform. Therefore, on platforms H that are not responsible for the station attendant who issued the voice, the text information converted from this voice is not displayed, and therefore passengers on other platforms that are not the target of voice guidance, etc., are not bothered by the display of text information indicating the content of the voice.
[0054] In other words, this display system 9 is an example of a display system that obtains information about the platform that a station attendant is responsible for and displays text information within the field of view of passengers waiting in front of the platform doors installed on that platform.
[0055] The processor 11 may obtain information indicating the platform number for which the station attendant is responsible, for example, directly from the microphone 2. In this case, for example, the station attendant may operate the operation unit 24 of the microphone 2 to input the platform number for which the station attendant is responsible, etc.
[0056] As described above, when the information processing device 1 acquires the platform information entered by the station staff into the microphone 2, this display system 9 is an example of a display system that acquires the platform information for which the station staff is responsible along with the voice of the station staff from the microphone used by the station staff, and displays text information within the field of view of passengers waiting in front of the platform doors installed at that platform.
[0057] Furthermore, in step S104 described above, the processor 11 of the information processing device 1 determines whether the urgency of the voice is equal to or greater than a predetermined level, and if it determines that the urgency is not equal to or greater than the predetermined level, returns the process to step S101. Therefore, when the urgency of the voice is not equal to or greater than the predetermined level, the voice recognition process is not executed on the voice, no text information is generated, and no instruction is given to display the text information, so passengers are not bothered by text indicating the content of the voice with a low level of urgency.
[0058] That is, this display system 9 is an example of a display system that determines the urgency of a voice and displays text information when the urgency is higher than a predetermined level.
[0059] Furthermore, when instructing the platform door device 3 to display text information, the processor 11 may also instruct the indicator light 37 to be turned on. In this case, the processor 11 may determine the manner in which the indicator light 37 is turned on depending on the level of urgency.
[0060] By executing the above-described processing, the information processing device 1 displays the voice of the station staff as text information to passengers waiting in front of the platform doors at the station. Therefore, by using this information processing device 1 in the display system 9, the content of the voice of the station staff can be conveyed as text information to passengers who are not paying attention to the voices in the station, including the hearing impaired.
[0061] The information processing device 1 in this display system 9 is a computer having a processor 11 and a memory 12. Therefore, the present invention is conceived as a display method that causes a computer to execute each of the steps shown in FIG.
[0062] The present invention can also be conceived as a program written to cause a computer to execute the steps shown in FIG.
[0063] The configurations, shapes, sizes, and layout relationships described in the above embodiments are merely schematic illustrations to enable understanding and implementation of the present invention. Therefore, the present invention is not limited to the described embodiments, and can be modified in various forms without departing from the scope of the technical ideas set forth in the claims.
[0064] <Modification> The above is a description of the embodiment, but the contents of this embodiment can be modified as follows. In addition, the following modifications can be combined.
[0065] <1> In the above-described embodiment, the display unit 35 was a monitor provided in the housing 30 of the platform door device 3, but the display unit 35 is not limited to a monitor. The display unit 35 may be, for example, a projector that projects an image onto a screen on the surface of the housing 30 or the surface of the platform door 36, whichever surface is within the field of view of passengers. Even in this case, the text information converted from the voice of the station staff through voice recognition processing is visible to passengers waiting in front of the platform door at the station. In other words, the display system 9 in this modified example is an example of a display system that displays text information converted from the voice of the station staff through voice recognition on the platform door or a housing that houses the platform door.
[0066] Note that the display of text information is not limited to the platform doors and the housings that house the platform doors. The text information indicating the content of the audio may also be displayed, for example, on a wall, pillar, or the like located between the tracks on which trains pass. In short, the text information only needs to be displayed within the field of view of passengers waiting in front of the platform doors at the station.
[0067] <2> In the above-described embodiment, the processor 11 of the information processing device 1 issues instructions to the platform door device 3 installed on the specified platform, but the platform responsible for the station staff does not have to be specified. In this case, the above-described text information is displayed on the platform door device 3 on all platforms, regardless of whether the platform is responsible for the station staff or not.
[0068] <3> In the above-described embodiment, the processor 11 of the information processing device 1 instructs the platform door device 3 to display text information only when the urgency of the voice is higher than a predetermined level, but it is not necessary to determine the urgency of the voice. In this case, the processor 11 may convert all acquired voice data into text information and instruct the platform door device 3 to display it. [Explanation of symbols]
