[0017] Figure 1 A control block diagram showing a voice announcement system for an elevator according to an exemplary embodiment of the present invention; and

[0018] Figure 2 The following is a flowchart showing a voice announcement system for an elevator according to an exemplary embodiment of the present invention.

[0019] It should be understood that the drawings are not drawn to scale, but show various features that illustrate the basic principles of the invention in a slightly simplified manner. In the drawings of the present invention, the same reference numerals represent the same or equivalent parts of the present invention. DETAILED DESCRIPTION

[0020] Reference will now be made in detail to various embodiments of the present invention, examples of which are shown in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments of the present invention, it should be understood that this specification is not intended to limit the present invention to the exemplary embodiments of the present invention described. On the other hand, the present invention is intended to cover not only the exemplary embodiments of the present invention, but also various alternative embodiments, modified embodiments, equivalent embodiments and other embodiments that may be included in the spirit and scope of the present invention defined by the appended claims.

[0021] The voice announcement system for an elevator according to an exemplary embodiment of the present invention can flexibly configure multiple languages ​​and conveniently adjust the volume, and can reduce the mutual influence between the voice announcement system and the elevator control system, thereby improving the user experience.

[0022] Hereinafter, a voice announcement system for an elevator according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0023] Figure 1 A control block diagram showing a voice announcement system for an elevator according to an exemplary embodiment of the present invention.

[0024] like Figure 1 As shown, the voice broadcast system for an elevator according to an exemplary embodiment of the present invention may include: a voice broadcast device 10, a data transceiver 20, and a parameter setting device 30. The voice broadcast device 10 and the data transceiver 20 may be arranged in the elevator car, and the parameter setting device 30 may be an external device arranged outside the elevator.

[0025] In an exemplary embodiment, the voice broadcasting device 10 may include: a memory 11 , a controller 12 , and a speaker 13 .

[0026] Specifically, the memory 11 of the voice broadcast device 10 can store a voice broadcast protocol 11a dedicated to the voice broadcast system. The voice broadcast system can use the dedicated voice broadcast protocol 11a to obtain the operating status of the elevator without reading information from the elevator control system, thereby reducing the mutual influence between the elevator control system and the voice broadcast system. The voice broadcast protocol 11a can be a custom protocol or a standard protocol, for example, CAN, RS-485 protocol.

[0027] In addition, the memory 11 can store a speech library 11b. The speech library 11b can include speech segments in multiple languages. Taking Chinese as an example, the speech segments can be stored in the form of single characters, for example, "one", "two", "three", "layer", "electric", "elevator", "to", "reach". The voice broadcast device 10 can combine the single characters stored in the speech library 11b to form phrases, and further combine the phrases into sentences. Alternatively, the speech segments can be stored in the form of phrases, for example, "one floor", "two floors", "three floors", "elevator", "reach". The voice broadcast device 10 can combine the phrases stored in the speech library 11b to form sentences.

[0028] Taking English as an example, the speech segments can be stored in the form of single words, for example, "one", "two", "three", "floor", "lift", "arrived", "at". The voice broadcast device 10 can combine the single words stored in the voice library 11b to form phrases, and further combine the phrases into sentences. Alternatively, the speech segments can be stored in the form of phrases, for example, "floor one", "floor two", "floor three", "lift arrived at". The voice broadcast device 10 can combine the phrases stored in the voice library 11b to form sentences.

[0029] Each speech segment stored in the speech library 11 b may have a unique speech segment ID, and each volume may also have a unique volume ID.

[0030] As an example, a three-digit number may be used to represent a voice segment ID, wherein the first digit of the three-digit number may represent the type of language. The voice segment ID of the Chinese voice segment "one" may be 100, the voice segment ID of the voice segment "two" may be 101, the voice segment ID of the voice segment "three" may be 102, and so on, wherein "1" in "100" may represent Chinese.

[0031] The speech segment ID of the English speech segment "one" may be 200, the speech segment ID of the speech segment "two" may be 201, the speech segment ID of the speech segment "third" may be 202, and so on, where the "2" in "200" may represent English.

[0032] In this case, the memory 11 may further store a mapping table 11c, which may include mappings between each speech segment and speech segment ID of each language. As shown in Tables 1 and 2 below, Table 1 shows a mapping table between speech segments and speech segment IDs of Chinese, and Table 2 shows a mapping table between speech segments and speech segment IDs of English. The number of language types is not limited thereto, and the language types in the speech library 11b may be more than three.

[0033] Table 1

[0035] Table 2

[0036] Voice Clips Voice segment ID one 200 two 201 three 202 floor 203 lift 204 arrived 205 at 206 …… ……

[0037] In addition, the mapping table 11c may further include a mapping between each volume and a volume ID, and the volume ID may be represented by two digits to distinguish it from the voice segment ID, as shown in Table 3 below.

[0038] Table 3

[0039]

[0040] In addition, the mapping table 11c may further include a mapping between a language type and a language type ID, and the language type ID may be represented by two digits, as shown in Table 4 below.

[0041] Table 4

[0042] Language Language ID Chinese 00 English 01 Chinese + English 02 English + Chinese 03 French 04 German 05 …… ……

[0043] The language type ID can indicate not only the language type played, but also the order in which the multiple languages ​​are played. For example, a language type ID of 02 can indicate that the languages ​​played include Chinese and English, and Chinese is played first, then English; a language type ID of 03 can indicate that the languages ​​played include Chinese and English, and English is played first, then Chinese.

[0044] When the voice segment, volume, and language type of the voice to be played are determined, the controller 12 may generate an instruction including a voice segment ID, a volume ID, and a language type ID.

[0045] Traditional voice announcement systems usually pre-record the content to be played as multiple MP3 files and store the MP3 files in the voice announcement system. For the need for bilingual playback, when the elevator arrives at a certain floor, the voice announcement system will play an MP3 file containing the content "elevator arrived at floor XX". When the type of language or the order of playback needs to be modified, the multiple MP3 files stored in the voice announcement system need to be replaced as a whole. Therefore, traditional voice announcement systems cannot achieve flexible configuration of multiple languages.

[0046] The voice announcement system for elevators of the present invention can be flexibly configured by combining the voice segments of multiple languages ​​stored in the voice library 11b. The voice announcement system for elevators of the present invention can generate voice using the voice segments in the voice library 11b in response to the voice announcement protocol 11a according to the setting of the parameter setting device 30.

[0047] In addition, the memory 11 may further store a music library 11d, which may include background music played in the elevator. The background music can not only relieve the anxiety and depression caused by the high-altitude and enclosed elevator environment, but also create a special atmosphere on special holidays. The voice clips in the voice library 11b and the background music in the music library 11d can be stored in any format of WAV and MP3.

[0048] The memory 11 according to the exemplary embodiment of the present invention may be any one of a volatile memory and a non-volatile memory. For example, the volatile memory may be a dynamic random access memory (DRAM) or a static random access memory (SRAM), wherein the dynamic random access memory may include at least one of a synchronous dynamic memory (SDRAM), a DDR SDRAM, a DDR2 SDRAM, and a DDR3 SDRAM. For example, the non-volatile memory may be at least one of a read-only memory (ROM), a flash memory, an optical disk, a floppy disk, and a hard disk.

[0049] The controller 12 of the voice broadcast device 10 can determine the voice to be played currently through the voice broadcast protocol (rather than by reading the information of the elevator control system). The controller 12 can obtain the floor that the current elevator has reached through the voice broadcast protocol 11a, and generate a voice including the floor that the current elevator has reached using the voice clips stored in the voice library 11b. In addition, the controller 12 can obtain the operating status of the current elevator through the voice broadcast protocol 11a, and when the elevator fails, the controller 12 can generate a voice including soothing content using the voice clips stored in the voice library 11b.

[0050] The speaker 13 of the voice broadcast device 10 can be arranged inside the elevator car to play the voice generated by the controller 12 including the floor the elevator currently arrives at and / or soothing content, and / or play background music.

[0051] The data transceiver 20 can be electrically connected to the voice broadcast device 10 so that the voice broadcast device 10 is connected to the external device by communication. The data transceiver 20 can be a debugging port and / or a wireless network module provided in the elevator. The data transceiver 20 can connect the voice broadcast device 10 to the external device by wired communication and / or wireless communication. The wired communication method can include at least one of CAN bus, Ethernet and RS-485. The wireless communication method can include at least one of Bluetooth and Wi-Fi. The external device can include a parameter setting device 30. The communication method between the voice broadcast device 10 and the external device (such as a wired communication protocol and / or a wireless communication protocol) can be included in the voice broadcast protocol 11a.

[0052] In addition, the voice broadcast protocol 11a may also include data formats, such as special states of the elevator, floor information, etc. In addition, the voice broadcast protocol 11a may include functions such as transmission of instructions, voice selection, and parameter setting. The voice broadcast protocol 11a may define the communication method and data format. On the one hand, the voice broadcast protocol 11a may ensure normal communication and data exchange between the parameter setting device 30 and the voice broadcast device 10. On the other hand, inside the elevator, the voice broadcast system may use the voice broadcast protocol 11a to communicate with the elevator control system and obtain information such as the operating state of the elevator.

[0053] The parameter setting device 30 can be connected to the voice broadcast device 10 through the data transceiver device 20 to set the parameters of the voice to be played generated by the controller 12 of the voice broadcast device 10. The parameter setting device 30 can send an instruction including a volume ID and a language type ID to the controller 12 of the voice broadcast device 10 using the voice broadcast protocol 11a. The controller 12 can control the speaker 13 to play the voice at a specified volume according to the volume ID included in the instruction, and can select a corresponding language in the voice library 11b according to the language type ID included in the instruction. When there are more than two language types, the controller 12 can sort each language in a specified order.

[0054] Specifically, the elevator can play voice in multiple languages. In this case, the controller 12 can select the corresponding language in the voice library 11b according to the language type used, and generate voice including multiple languages ​​according to the playback order of each language. When setting the parameters of the voice, first connect the parameter setting device 30 to the voice broadcast device 10 through the data transceiver 20. The parameter setting device 30 can have a user interface, and the user interface can include language type options, playback order options, and volume options. The user can set it through the user interface of the parameter setting device 30. After the user setting is completed, the parameter setting device 30 can generate an instruction including a volume ID and a language type ID according to the user setting, and send the generated instruction to the voice broadcast device 10 through the data transceiver 20 using the voice broadcast protocol 11a. The parameter setting device 30 can be at least one of a mobile phone, a computer, and a tablet computer.

[0055] Furthermore, the controller 12 can be divided into a language module 12a, a volume module 12b and a speech generation module 12c according to the functions.

[0056] When generating speech, first, the language module 12a of the controller 12 can determine the language type and the playback order according to the parameters of the speech set by the parameter setting device 30. Specifically, according to the language type ID included in the instruction received from the parameter setting device 30, the language module 12a can determine the language type and the playback order by querying the mapping table of language types and language type IDs shown in Table 4. For example, the language type ID in the instruction can be 02, and the language module 12a can determine that the language types are Chinese and English by querying Table 4, and the playback order is to play Chinese once and then play English once.

[0057] Next, the volume module 12b of the controller 12 can determine the volume of the voice according to the parameters of the voice set by the parameter setting device 30. Specifically, according to the volume ID included in the instruction received from the parameter setting device 30, the volume module 12b can determine the volume of the voice by querying the mapping table of volume and volume ID shown in Table 3. For example, the volume ID in the instruction can be 04, and the volume module 12b can determine that the volume is 50 decibels by querying Table 3.

[0058] Finally, the voice generation module 12c of the controller 12 can determine the voice to be played through the voice broadcast protocol 11a. The voice generation module 12c can determine the floor that the current elevator arrives at through the voice broadcast protocol 11a, and generate a voice including the floor that the current elevator arrives at. Specifically, the language type and the play order determined by the language module 12a and the volume determined by the volume module 12b can be sent to the voice generation module 12c. The voice generation module 12c can select the voice segments required to represent the floor that the current elevator arrives at from the Chinese and English voice segments in the voice library 11b, combine the selected Chinese voice segments into a sentence A representing the floor that the current elevator arrives at, and combine the selected English voice segments into a sentence B representing the floor that the current elevator arrives at. The voice generation module 12c can arrange the combined sentences A and B in the order of Chinese first and English later. The voice generation module 12c can control the speaker 13 to play the sentences A and B arranged in order at a volume of 50 decibels.

[0059] In an exemplary embodiment, the controller 12 may further include a background music module 12d. The background music module 12d may determine whether to play the background music according to the parameters of the background music set by the parameter setting device 30. The user may select whether to play the background music and select the background music to be played through the user interface of the parameter setting device 30. The background music module 12d may select the background music to be played from the music library 11d and may control the speaker 13 to play the background music.

[0060] In this case, the volume module 12b can also determine the volume of the background music. The user can set the volume of the background music through the user interface of the parameter setting device 30. The background music module 12d can control the speaker 13 to play the background music according to the set volume of the background music.

[0061] Figure 2 The following is a flowchart showing a voice announcement system for an elevator according to an exemplary embodiment of the present invention.

[0062] like Figure 2 As shown, in step S101 , the voice broadcasting device 10 and the parameter setting device 30 can be connected by wire or wirelessly through the data transceiver device 20 .

[0063] When the voice broadcasting device 10 is connected to the parameter setting device 30 , in step S102 , the parameter setting device 30 can be used to set the voice parameters required by the voice broadcasting device 10 when generating voice.

[0064] When the language type selected by the user is more than two, it is necessary to set the playback order of each language. At the same time, the user can select the volume of the voice to be played through the parameter setting device 30, without having to manually adjust the volume on the top of the elevator car like in a traditional elevator.

[0065] When the voice parameter setting is completed, in step S103, the parameter setting device 30 may generate an instruction including the volume ID and the language type ID, and send the instruction including the volume ID and the language type ID to the controller 12 of the voice broadcast device 10 using the voice broadcast protocol 11a.

[0066] Next, in step S104, the language module 12a of the controller 12 can determine the language type and the play order according to the language type ID included in the received instruction, and send the determined language type and play order to the speech generation module 12c. For example, the language type ID can be 02, that is, including Chinese and English, and playing Chinese first and then playing English.

[0067] In step S105, the volume module 12b of the controller 12 may determine the volume of the speech according to the volume ID included in the received instruction, and send the determined volume to the speech generation module 12c. For example, the volume ID may be 04, that is, the volume may be 50 decibels.

[0068] In step S106 , the voice generation module 12 c of the controller 12 may determine the voice to be played through the voice broadcasting protocol 11 a and generate the voice to be played.

[0069] As an example, during the operation of the elevator, when the elevator reaches the first floor, the speech generation module 12c of the controller 12 can generate a speech including the current elevator reaching the first floor. Specifically, the speech generation module 12c can determine that the current elevator has reached the first floor through the speech broadcast protocol 11a. Accordingly, the speech generation module 12c can select the speech segment required to indicate that the current elevator has reached the first floor from the Chinese and English speech segments in the speech library 11b.

[0070] The speech generation module 12c can select speech segment IDs 100, 103, 104, 105, 106 and 107 from the above Table 1, and select speech segment IDs 200, 203, 204, 205 and 206 from the above Table 2 according to the language type received from the language module 12a. The speech generation module 12c can arrange the speech segment IDs of Chinese in the order of 104, 105, 106, 107, 100 and 103, thereby combining single words into the sentence "the elevator has reached one floor", and can also arrange the speech segment IDs of English in the order of 204, 205, 206, 203 and 200, thereby combining single words into the sentence "lift arrived at floor one".

[0071] Next, the speech generation module 12c may generate the Chinese speech segment IDs and the English speech segment IDs into a sequence of 104, 105, 106, 107, 100, 103, 204, 205, 206, 203 and 200 in the order of Chinese first and English later.

[0072] The sequence generated by the speech generation module 12c may further include a volume ID, namely, volume ID 04 with a volume of 50. Therefore, the sequence finally generated by the speech generation module 12c may be: 04, 104, 105, 106, 107, 100, 103, 204, 205, 206, 203 and 200.

[0073] In step S107, the speech generation module 12c can control the speaker 13 to play the generated speech. The speaker 13 can play the speech of the sentence "lift arrived at floor one" at a volume of 50 according to the sequence finally generated by the speech generation module 12c.

[0074] In an exemplary embodiment, in step S102, the parameters of the background music can also be set by the parameter setting device 30. The user can choose whether to play the background music, the background music to be played and the volume of the background music through the user interface. Accordingly, the background music stored in the voice library 11b can have a unique background music ID, and the background music ID of each background music can be pre-stored in the memory 11. The parameter setting device 30 can generate an instruction including the background music ID. In step S103, the parameter setting device 30 can send the instruction including the background music ID to the controller 12 of the voice broadcast device 10 together with the instruction including the language type ID and the volume ID.

[0075] Steps S108 to S110 may be further included after step S103. The background music module 12d of the controller 12 may determine whether to play the background music according to the received background music ID. When it is determined that the background music is to be played, in step S108, the background music module 12d may select the background music to be played from the music library 11d. In step S109, the volume module 12b may determine the volume of the background music.

[0076] In step S110, the background music module 12d may control the speaker 13 to play the selected background music at the set background music volume.

[0077] Through the above method, the setting of the voice broadcast device can be completed through the parameter setting device, and the voice broadcast device can generate corresponding voice according to the setting and play the generated voice through the speaker set in the elevator.

[0078] The voice announcement system for an elevator according to an exemplary embodiment of the present invention may include a dedicated voice announcement protocol without reading information from the elevator control system, thereby reducing the mutual influence between the elevator control system and the voice announcement system.

[0079] The voice announcement system for an elevator according to an exemplary embodiment of the present invention can pre-store voice clips in multiple languages, generate voice using the voice clips in response to the voice announcement protocol, and thus can flexibly configure multiple languages ​​played in the elevator.

[0080] The voice broadcast system for an elevator according to an exemplary embodiment of the present invention can conveniently adjust the volume of the voice played in the elevator through the parameter setting device.

[0081] The above descriptions of the specific exemplary embodiments of the present invention are presented for the purpose of illustration and description. They are not intended to be exhaustive or to limit the present invention to the precise form disclosed, and it is obvious that many modifications and changes can be made according to the above teachings. The selection and description of the exemplary embodiments are to explain certain principles of the present invention and their practical applications, so that those skilled in the art can make and use various exemplary embodiments of the present invention and their different alternative forms and modified forms.
