Fig. 1 is a schematic diagram illustrating interaction between a server 100 and a mobile terminal 200 and a projector 300 according to an embodiment of the present invention. The server 100 is communicatively connected with the mobile terminal 200 and the projector 300 through the network 400 for data communication or interaction, and the communication connection established between the projector 300 and the server 100 may be a long connection. The server 100 may be a web server, a database server, an access server, a storage server, or the like. The mobile terminal 200 may be a Personal Computer (PC), a tablet PC, a smart phone, a Personal Digital Assistant (PDA), and the like.
First embodiment
Fig. 2 shows a voice interaction method for a projector according to an embodiment of the present invention, and referring to fig. 2, the method includes:
step S110: the mobile terminal sends voice information to the server.
When voice interaction with the projector 300 is required and voice information is transmitted to the projector 300, a user may input the voice information desired to be transmitted through the mobile terminal 200. Of course, it is understood that the manner in which the user inputs the voice information may be voice entry through a microphone or the like of the mobile terminal 200.
The mobile terminal 200 transmits the received voice information input by the user to the server 100.
Step S120: the server stores the voice information and generates index information associated with the voice information.
After receiving the voice information transmitted by the projector 300, the server 100 stores the voice information and generates index information associated with the stored voice information, where the index information may include a storage location of the voice information.
Step S130: and the server sends the index information to a projector.
The server 100 transmits the generated index information to the projector 300.
Specifically, in this embodiment, the voice message sent by the mobile terminal 200 may include an identification code of the projector 300, where the identification code corresponds to a unique projector 300, and the corresponding projector 300 is the projector 300 that the voice message wants to send. The identification code and the correspondence between the identification code and the projector 300 may be stored in the server 100 in advance, and the server 100 may search the projector 300 corresponding to the identification code according to the identification code of the projector 300 included in the voice information, and send the index information to the searched projector 300.
Further, in the present embodiment, the server 100 may transmit the index information to the corresponding projector 300 again in a case where the mobile terminal 200 has the authority to transmit the voice information to the corresponding projector 300. The authority of the mobile terminal 200 to transmit voice information to the projector 300 may be satisfied in a case where the mobile terminal 200 has a pairing relationship with the projector 300. The pairing of the mobile terminal 200 and the projector 300 may be understood as mutual binding between the mobile terminal 200 and the projector 300, and may be specifically represented as that the mobile terminal 200 and the identification code of the projector 300 to which the voice information is to be transmitted have a pairing relationship, that is, the mobile terminal 200 and the identification code in the transmitted voice information have a corresponding pairing relationship, and it may be understood that the pairing relationship is stored in the server 100.
Then, as shown in fig. 3, before sending the index information to the projector 300 in step S130, step S121 is further included: the server determines whether the mobile terminal and the projector are paired, and if so, executes step S130.
Specifically, the voice message may further include an identity of the mobile terminal 200, and the server 100 may determine whether the mobile terminal 200 and the projector 300 are paired, where the server 100 searches for an identifier code paired with the identity according to the identity of the mobile terminal 200; when the identification code paired with the identity identifier is found, the server 100 determines whether the found identification code is consistent with the identification code in the voice message, and if so, determines that the mobile terminal 200 is paired with the projector 300, and may send the generated index information to the projector 300.
Of course, if the server 100 does not find the identification code paired with the identity identifier or the found identification code is not consistent with the identification code in the voice message, it is determined that the mobile terminal 200 and the projector 300 are not paired, and the index information is not sent to the projector 300. Also, when the mobile terminal 200 is unpaired with the projector 300, the server 100 may feed back unpaired information to the mobile terminal 200 and feed back information that voice information transmission failed.
In this embodiment, the determination of whether the mobile terminal 200 and the projector 300 are paired may be that the steps S120 and the following steps are not executed if the mobile terminal 200 and the projector 300 are not paired before the voice information is stored and the index information is generated in step S120.
In addition, in this embodiment, the projector 300 may be in the on state and then send the index information to the projector 300, and as shown in fig. 4, before step S130, step S122 may be further included: the server 100 determines whether the projector 300 is in the on state, and if so, executes step S130.
When projector 300 is in the on state, server 100 transmits the generated index information to projector 300, and projector 300 should be in the network connection state at this time. If the projector 300 is in the power-off state or in the state of network disconnection with the server, the server 100 does not send the index information to the projector 300, and the condition that the projector 300 is in the power-off state or the network connection is disconnected can be fed back to the mobile terminal 200. In addition, in the case where the index information is not transmitted to projector 300 because projector 300 is in the off state or the network connection is disconnected, server 100 may periodically detect the on state or the network connection state of projector 300, and when projector 300 is in the on state or the network connection state, server 100 transmits the index information to projector 300.
In this embodiment, the determination of whether the projector 300 is in the on state may be that after the determination of whether the mobile terminal 200 and the projector 300 are paired, after determining that the mobile terminal 200 and the projector 300 are paired, it is determined whether the projector 300 is in the on state.
Step S140: and the projector acquires the voice information from the server according to the index information.
After receiving the index information, the projector 300 may acquire the voice information from the server 100 according to the index information, and the acquiring process may be understood as a downloading process. After the projector 300 acquires the voice information, the server 100 may feed back to the mobile terminal 200 a message that the projector 300 successfully receives the voice information.
Since the network environment where the projector 300 is located may be a mobile communication network such as a 3G network and a 4G network or a wireless network such as a WiFi network, and since the 3G network and the 4G network are expensive, if the cost for transmitting the voice information using the 3G network or the 4G network is high, the projector 300 may obtain the voice information from the server 100 according to the index information in the WiFi network.
Therefore, in a specific implementation manner of this embodiment, after receiving the index information, the projector 300 may first detect whether the current network environment is a WiFi network, and if so, execute the step of the projector 300 acquiring the voice information from the server 100 according to the index information in step S140. If the current network environment is the 3G network or the 4G network, the projector 300 does not execute the voice information acquisition in step S140, or the projector 300 reminds the user whether to acquire the voice information in the current mobile network environment, and if so, acquires the voice information from the server 100 according to the index information.
In this embodiment, a specific manner of acquiring the voice information from the server 100 by the projector 300 according to the index information may be as shown in fig. 5:
step S141: and the projector sends a voice acquisition request to the server, wherein the voice acquisition request comprises the index information.
When the projector 300 receives the index information, if the voice information needs to be acquired, a voice acquisition request is sent to the server 100. The corresponding index information received by the projector 300 is included in the voice acquisition request.
Step S142: and the server receives the voice acquisition request and searches the stored voice information according to the index information.
Since the index information is related to the voice information and the storage location of the voice information, the server 100 may find the stored voice information related to the index information according to the index information.
Step S143: and the server sends the searched voice information to the projector.
It is understood that the server 100 transmits the searched voice information to the projector 300 that made the voice acquisition request.
Step S144: the projector receives the voice information.
The projector 300 receives the voice information transmitted from the server 100.
Step S150: and the projector plays the voice information.
The projector 300 plays the obtained voice information, and the voice interaction of the mobile terminal 200 to the projector is realized.
Second embodiment
In this embodiment, the server 100 includes a first server and a second server, the first server 100 may be configured to interact with the projector 300 and the mobile terminal 200, and the second server 100 may be configured to store the voice information, so in this embodiment, as shown in fig. 6, the step of the mobile terminal 200 sending the voice information to the projector 300 through the server 100 may be:
step S210: the mobile terminal 200 transmits voice information to the first server 100.
In the process of transmitting the voice information to the server by the mobile terminal 200, the mobile terminal transmits the voice information to the first server, and the transmitted voice information further includes path information for generating index information, the path information including a transmission path by which the generated index information is transmitted to the projector. In this embodiment, the sending path in the path information may be the first path or the second path, and specifically, the first path or the second path may be selected by the user when sending the voice information, or may be preset.
The first path is that the first server sends the index information to the second server through the mobile terminal and then the second server sends the index information to the projector, and the second path is that the first server directly sends the index information to the second server and then the second server sends the index information to the projector. In this embodiment, when the first server and the second server do not have the direct communication right, the sending path in the path information may be the first path, and certainly, when the first server and the second server have the direct communication right, the sending path in the path information may be the first path or the second path.
Step S220: and the first server stores the voice information, generates index information associated with the voice information, and determines a sending path of the index information according to the path information.
And after receiving the voice information, the first server stores the voice information and generates index information. After the index information is generated, the sending path of the index information is determined according to the path information in the voice information.
Step S230: when the sending path is a first path, the first server sends the index information to the mobile terminal, the mobile terminal sends the index information to the second server, and the second server sends the index information to a projector; and when the sending path is a second path, the first server sends the index information to the second server, and the second server sends the index information to the projector.
And according to different sending paths, the server sends the index information to the projector in different modes.
Specifically, after the sending path is determined to be the first path, the first server sends the index information to the mobile terminal, then the index information is sent to the second server through the mobile terminal, and finally the index information is sent to the projector through the second server.
And when the sending path is determined to be the second path, the first server directly sends the index information to the second server, and the second server sends the index information to the projector after receiving the index information.
Step S240: : and the projector acquires the voice information from the first server according to the index information.
In the step of the projector acquiring the voice information from the server according to the index information, the projector acquires the stored voice information from the first server according to the index information.
Third embodiment
In the voice interaction method of the projector provided in this embodiment, the method may further include sending voice information to the mobile terminal 200 by the projector 300 as shown in fig. 7. Referring to fig. 7, the projector 300 transmitting the voice information to the mobile terminal 200 may include:
step S310: the projector 300 transmits another voice message to the server 100.
Step S320: the server 100 stores the other voice information and generates other index information associated with the other voice information.
Step S330: the server 100 transmits the other index information to the mobile terminal 200.
Step S340: the mobile terminal 200 acquires the other voice information from the server 100 according to the other index information.
It is understood that, in the present embodiment, a method in which the projector 300 transmits another voice message to the mobile terminal 200 through the server 100 is similar to a method in which the mobile terminal 200 transmits a voice message to the projector 300 through the server 100.
In this embodiment, the voice information sent by the projector to the mobile terminal may be recorded through a remote controller of the projector, and of course, the voice information may also be directly recorded by the projector or recorded through other manners. The sending process of the other voice message by the projector can also be carried out under the control of a remote controller, or directly operated by the projector, or carried out by other modes.
Before step S330 in this embodiment, the server 100 may determine whether the projector 300 is paired with the mobile terminal 200 to which the voice information is to be transmitted, and if so, perform the step of transmitting another index information to the mobile terminal 200. When the mobile terminal 200 acquires another voice message, the another voice message may be played.
Further, if the server 100 determines that the projector 300 is not paired with the mobile terminal 200, the step of transmitting another index information to the mobile terminal 200 is not performed, and information of a failure in the transmission of the voice information may be fed back to the projector 300.
When the mobile terminal 200 obtains another index information, the server 100 may feed back a message that the voice information transmission is successful to the projector 300.
Of course, in this embodiment, the mobile terminal 200 may perform the step of acquiring the another voice message from the server 100 according to the another index information only when detecting that the current network environment is the WiFi network.
Further, in this embodiment, the server 100 may also include a first server and a second server, where the first server receives another voice message sent by the projector 300 and stores the another voice message, and generates another index information associated with the another voice message, where the another index information includes a storage location of the another voice message. The other voice information comprises path information of the other index information, and the first server determines a sending path of the other index information according to the path information of the other index information. When the sending path of the other index information is the first path, the first server sends the other index information to the projector, the projector sends the other index information to the second server, and the second server sends the other index information to the mobile terminal, so that the mobile terminal can obtain the other voice information from the first server according to the other index information. When the sending path of the other index information is a second path, the first server directly sends the other index information to the second server, and the second server sends the other index information to the mobile terminal.
