Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart of a voice broadcast method according to an exemplary embodiment of the present disclosure. The method can be applied to the vehicle-mounted horn. As shown in fig. 1, the method may include S101 to S106.
And S101, sending an authorization code to the vehicle-mounted terminal in response to receiving the broadcast request sent by the vehicle-mounted terminal.
As an example, an authorization code in the vehicle horn may be preset. As another example, the authorization code in the in-vehicle horn may be generated instantaneously by the authorization code generation module in the in-vehicle horn. When receiving a broadcast request sent by the vehicle-mounted terminal, the vehicle-mounted loudspeaker sends an authorization code to the vehicle-mounted terminal, and the authorization code can be used for the vehicle-mounted terminal to generate a second ciphertext. The vehicle-mounted loudspeaker and the vehicle-mounted terminal CAN perform information interaction through respective CAN communication modules.
And S102, receiving a first ciphertext generated by the vehicle-mounted terminal according to the authorization code.
And S103, generating a second ciphertext according to the authorization code.
For example, the second ciphertext may be generated by an encryption module in the vehicle-mounted horn, for example, the authorization code is input into an encryption program preset by the vehicle-mounted horn encryption module to obtain the second ciphertext. It should be noted that, in the present disclosure, the execution sequence of S102 and S103 is not specifically limited, for example, S102 may be executed first and then S103 may be executed, S102 and S103 may also be executed simultaneously, in fig. 1, S102 and S103 are executed first and then S103 is executed, which is exemplified and not limited in the present disclosure.
And S104, if the first ciphertext is consistent with the second ciphertext, sending a first broadcast password to the vehicle-mounted terminal.
For example, if a first ciphertext generated by the vehicle-mounted terminal according to the authorization code and a second ciphertext generated by the vehicle-mounted speaker, which are received by the vehicle-mounted speaker, are consistent, it may be determined that the vehicle-mounted terminal and the vehicle-mounted speaker are successfully authenticated in an authorization code encryption manner. The vehicle-mounted terminal acquires the authentication of the vehicle-mounted loudspeaker, and the vehicle-mounted loudspeaker can send a first broadcast password to the vehicle-mounted terminal at the moment. Through sending first report password to vehicle terminal, can get into and report the flow. Wherein, first report password can be generated immediately through the report password generation module in the on-vehicle loudspeaker to store to the memory cell in.
And S105, receiving a second broadcast password and broadcast content sent by the vehicle-mounted terminal.
S106, if the first broadcast password is consistent with the second broadcast password, voice broadcast is carried out according to broadcast contents.
Exemplarily, if the second broadcast password received by the vehicle-mounted speaker and sent by the vehicle-mounted terminal is the same as the first broadcast password stored in the vehicle-mounted speaker storage unit, it may be determined that the broadcast content is from the correct vehicle-mounted terminal, and the voice broadcast is performed according to the broadcast content.
By comparing the first ciphertext with the second ciphertext, whether the vehicle-mounted terminal passes the authentication of the vehicle-mounted loudspeaker or not can be determined; when the authentication is passed, whether the broadcast content comes from a required vehicle-mounted terminal can be determined through a comparison result of the first broadcast password and the second broadcast password, so that whether the broadcast content is broadcast or not can be determined. So, can be so that a plurality of vehicle terminals can carry out voice broadcast through same on-vehicle loudspeaker, realize the shared use of on-vehicle loudspeaker in the vehicle, need not to install repeated report device in the vehicle. Meanwhile, the broadcasting content can be ensured to come from a correct vehicle-mounted terminal, and the accuracy of voice broadcasting is ensured.
Optionally, the voice broadcasting method may further include:
and if the first ciphertext is inconsistent with the second ciphertext, generating a first indication message for indicating that the vehicle-mounted terminal and the vehicle-mounted loudspeaker fail to authenticate.
For example, when different vehicle-mounted terminals authenticate with the vehicle-mounted horn, different vehicle-mounted terminals may generate different ciphertexts because the authorization codes corresponding to the different vehicle-mounted terminals are different, and under the condition that the vehicle-mounted terminal B and the vehicle-mounted horn authenticate, if the vehicle-mounted terminal a generates signal interference on the vehicle-mounted terminal B, a first cipher text received in the authentication process of the vehicle-mounted terminal B and the vehicle-mounted horn may be sent by the vehicle-mounted terminal a. At this moment, the second ciphertext generated in the vehicle-mounted loudspeaker corresponds to the vehicle-mounted terminal B, namely the first ciphertext is inconsistent with the second ciphertext, and under the condition, the vehicle-mounted loudspeaker can perform voice broadcast on the first indication message of 'authentication failure of the vehicle-mounted terminal and the vehicle-mounted loudspeaker'. Alternatively or additionally, the vehicle-mounted loudspeaker can transmit the first indication message to the vehicle-mounted display screen and display the first indication message through the vehicle-mounted display screen. So, under the condition that on-vehicle terminal and on-vehicle loudspeaker authentication failed, indicate the user to in time know the authentication condition in the user, promote user's use and experience and feel.
Optionally, the voice broadcasting method may further include:
and if the second broadcast password is inconsistent with the first broadcast password, generating a second indication message for indicating that the broadcast fails.
Exemplarily, if the currently communicating vehicle-mounted terminal is interfered by other vehicle-mounted terminals, an error may be generated in the process of receiving and sending the broadcast password, so that the second broadcast password is inconsistent with the first broadcast password, and the vehicle-mounted speaker can perform voice broadcast on the second indication message of 'broadcast failure'. Alternatively or additionally, the vehicle-mounted horn may transmit the above-mentioned second indication message to the vehicle-mounted display screen, and display the above-mentioned second indication message through the vehicle-mounted display screen. So, under the condition of broadcasting the failure, indicate the user, promote user's use and experience the sense.
Optionally, before sending an authorization code to the vehicle-mounted terminal in response to receiving a broadcast request sent by the vehicle-mounted terminal, the voice broadcast method may further include:
receiving an authentication code sent by a vehicle-mounted terminal;
and if the received authentication code is consistent with the preset authentication code, determining that the vehicle-mounted terminal is legal equipment.
Illustratively, before the vehicle-mounted terminal is determined to be a legal device, the vehicle-mounted loudspeaker is only allowed to judge the received authentication code, and does not process the received other information. The vehicle-mounted loudspeaker can store a preset authentication code, a user can acquire the preset authentication code in the vehicle-mounted loudspeaker through channels such as a vehicle-mounted loudspeaker use specification and the like, the preset authentication code is input into the vehicle-mounted terminal through a touch screen or a keyboard of the terminal device, and the vehicle-mounted terminal sends the authentication code input by the user to the vehicle-mounted loudspeaker so that the vehicle-mounted loudspeaker authenticates the legality of the vehicle-mounted terminal. Alternatively, the user may also input an authentication code through a mobile terminal matched with the vehicle-mounted terminal, such as a mobile phone, and send the authentication code input by the user to the vehicle-mounted terminal and then to the vehicle-mounted loudspeaker. And if the authentication code received by the vehicle-mounted loudspeaker is consistent with the preset authentication code, determining that the vehicle-mounted terminal is legal equipment. Therefore, the information interaction between the vehicle-mounted loudspeaker and illegal equipment can be avoided, and the safety of the user information of the vehicle-mounted loudspeaker is improved. After the vehicle-mounted terminal is confirmed to be legal equipment, the vehicle-mounted loudspeaker can perform normal information interaction with the vehicle-mounted terminal.
After the vehicle-mounted loudspeaker determines that the vehicle-mounted terminal is legal equipment, the equipment information of the vehicle-mounted terminal can be stored in the storage module, so that after the vehicle-mounted loudspeaker determines that the vehicle-mounted terminal is legal equipment for the first time, whether the vehicle-mounted terminal is legal equipment or not does not need to be confirmed through the authentication code again in the later use process.
Fig. 2 is a flowchart of a voice broadcast method according to an exemplary embodiment of the present disclosure. The method can be applied to the vehicle-mounted terminal. As shown in fig. 2, the method may include S201 to S205.

Illustratively, the user can also directly send the broadcast request through the vehicle-mounted terminal, if the broadcast request is sent through the display screen of the vehicle-mounted terminal, a voice broadcast function switch button can be displayed on the display screen, and the user can set whether the switch of the voice broadcast function is turned on. If the user sets the switch to be in the opening state, the vehicle-mounted terminal can send a broadcast request to the vehicle-mounted loudspeaker through the communication module. Alternatively, a voice broadcast function physical switch can be installed on the vehicle-mounted terminal, and a user can set whether the voice broadcast function of the vehicle-mounted terminal is started or not by operating the physical switch. So, can accurately acquire user's intention, open the voice broadcast function that corresponds vehicle mounted terminal when the user confirms that needs voice broadcast, make the vehicle more intelligent, promote user experience and feel.
For example, if important vehicle state prompt information is generated in the vehicle-mounted terminal in the use process of the vehicle, a broadcast request can be directly sent to the vehicle-mounted loudspeaker, so that a user can know the vehicle state in time, and the occurrence of accidents is reduced. In this case, the important vehicle state prompt information may be preset, for example, the vehicle electric quantity or the fuel quantity is insufficient.

And S204, sending a first ciphertext to the vehicle-mounted loudspeaker.
S205, responding to the received broadcast password sent by the vehicle-mounted loudspeaker, sending the broadcast password and the broadcast content to the vehicle-mounted loudspeaker, so that the vehicle-mounted loudspeaker determines whether to perform voice broadcast according to the broadcast content according to the received broadcast password.
Exemplarily, if the vehicle mounted terminal receives the broadcast password sent by the vehicle mounted speaker, the broadcast password and the broadcast content can be sent to the vehicle mounted speaker, wherein the broadcast password sent to the vehicle mounted speaker can be used for the vehicle mounted speaker to determine that the broadcast content comes from a correct vehicle mounted terminal, so as to avoid the vehicle mounted speaker to broadcast wrong broadcast content. If the broadcast password that vehicle loudspeaker received is unanimous with the broadcast password of storage, then can carry out voice broadcast according to broadcasting the content.
And the vehicle-mounted loudspeaker can confirm whether the authentication with the vehicle-mounted terminal is successful or not through the transmitted first ciphertext. And then, the broadcast content can be determined to come from the correct vehicle-mounted terminal by comparing the broadcast passwords so as to prevent the vehicle-mounted loudspeaker from broadcasting wrong content.
