The following describes in detail a control method and a control device for an in-vehicle device provided in an embodiment of the present application, but the present application is not limited thereto.
Fig. 1 is a flowchart of a control method of an on-vehicle device according to an embodiment of the present application, where the control method of the on-vehicle device is applied to the on-vehicle device. Referring to fig. 1, the control method of the in-vehicle apparatus includes the following steps 110 to 140.
In the embodiment of the application, the vehicle-mounted equipment can be a vehicle-mounted video recorder. The vehicle-mounted video recorder can record relevant information such as video images, sound and the like of a scene in the process of driving or parking the automobile.
In step 110, a wifi module accessed through a local designated interface is detected.
The local interface is a port which is arranged on the vehicle-mounted equipment and used for accessing the external equipment. The local designated interface is a specific interface used for accessing the wifi module. The local interface may be, for example, a USB (Universal Serial Bus wireless) interface.
In one embodiment, the step 110 of detecting a wifi module accessed through a local designated interface may be implemented by the following steps 111 and 112.
In step 111, whether a wifi module is inserted into the local designated interface is detected.
In step 112, if yes, the wifi module is accessed; if not, return to step 111.
In step 120, under the condition that the access of the wifi module is detected, broadcasting the wireless hotspot of the wifi module so as to inform the mobile terminal to access the wifi module through the wireless hotspot.
In one embodiment, referring to fig. 2, in case of detecting access to the wifi module, the step 120 of broadcasting the wireless hotspot of the wifi module may be accomplished by the following steps 121 and 122.
In step 121, in the case of detecting that the wifi module is accessed, loading the driver of the wifi module and configuring the broadcast parameters.
In step 122, broadcasting is performed according to the configured broadcasting parameters.
After the vehicle-mounted equipment detects that the accessed wifi module is matched, parameters are configured for the wifi module. The vehicle-mounted device is mainly configured with parameters such as wifi essid (extended service set Identifier, that is, the name of wifi) of the wifi module, SSID (service set Identifier) broadcast start, and a connection password of a wireless hotspot of the wifi module. When the vehicle-mounted equipment is provided with the wifi module to start SSID broadcasting, other equipment can search the wireless hotspot of the wifi module and access the wireless hotspot.
In one embodiment, referring to fig. 3, the process of accessing the wireless hotspot by the mobile terminal may be completed through the following steps 123 to 126.
In step 123, the mobile terminal searches for a wireless hotspot of the accessory.
In step 124, after searching for the wireless hotspot of the wifi module, the mobile terminal receives an externally input wireless password and sends a connection request for accessing the wireless hotspot to the wireless module, where the connection request carries the wireless password.
In step 125, the wifi module receives the connection request sent by the mobile terminal, and determines whether the wireless password carried by the connection request is consistent with the preset connection password.
In step 126, when the wifi module judges that the wireless password is consistent with the preset password, the mobile terminal is allowed to access the wifi module through the wireless hotspot; if not, return to step 123.
For safety, when the mobile terminal sends the wireless password input by the user to the wifi module, the wireless password can be encrypted. The wifi module receives the encrypted wireless password and decrypts the wireless password, and then judges whether the decrypted wireless password is consistent with a preset connection password. The preset connection password is the connection password of the wireless hotspot configured by the wifi module of the vehicle-mounted device.
In step 130, according to an access request sent by the mobile terminal through the wifi module to access the vehicle-mounted device, a connection between the vehicle-mounted device and the mobile terminal is established.
In one embodiment, referring to fig. 4, the process of establishing the connection between the vehicle-mounted device and the mobile terminal may be implemented through the following steps 131 to 133.
In step 131, an access request sent by the mobile terminal through the wifi module to access the vehicle-mounted device is received.
The mobile terminal may be a terminal integrated with an APP for controlling the in-vehicle device. The mobile terminal can be provided with a display screen and can display the interface of the APP for controlling the vehicle-mounted equipment.
In one embodiment, after opening the APP, the mobile terminal presents a login interface, which can be used for the user to enter an authentication password. The mobile terminal receives an authentication password input by a user to the login interface, and sends an access request for accessing the vehicle-mounted device to the vehicle-mounted device so as to request to establish connection with the vehicle-mounted device through an SDK (software development kit), wherein the access request carries the authentication password.
In another embodiment, after the mobile terminal is accessed to the wifi module through the wireless hotspot, an access request can be automatically sent to the vehicle-mounted device through the wifi module, and the verification password carried by the access request is the same as the wireless password input by the user. In this case, the user can input the password to the mobile terminal once, which further simplifies the operation of the user.
And then, the vehicle-mounted equipment receives the verification password sent by the mobile terminal through the wifi module.
In step 132, it is determined whether the verification password carried by the access request is consistent with a preset password.
Generally, for security, the authentication password carried by the access request sent by the mobile terminal to the vehicle-mounted device is a password encrypted by using a public key. Correspondingly, after the vehicle-mounted equipment receives the access request sent by the mobile terminal through the wifi module, the verification password carried by the received access request needs to be decrypted by a private key matched with the public key. Then the step 132 of determining whether the verification password carried by the access request is consistent with the preset password comprises: and judging whether the decrypted verification password is consistent with the preset password. Wherein, the public key can be RSA public key, and the private key can be RSA private key.
In step 133, if yes, a connection between the vehicle-mounted device and the mobile terminal is established.
If the vehicle-mounted device judges that the verification password carried by the received access request is consistent with the preset password, the vehicle-mounted device is allowed to access through the wifi module, and the vehicle-mounted device is communicated with the mobile terminal through the wifi module.
When the vehicle-mounted equipment judges that the verification password carried by the received access request is consistent with the preset password, prompt information of successful connection can be sent to the mobile terminal, and the APP of the mobile terminal is switched to be a control interface.
A part of the control interface of the APP may present relevant control buttons for controlling the in-vehicle device, which may be touch buttons or voice control buttons. After the user clicks the touch button, the mobile terminal can acquire a control instruction corresponding to the touch button, and therefore the vehicle-mounted equipment executes corresponding operation after receiving the control instruction. Signals generated by touch buttons on the control interface of the APP can carry different identifications or are different identifications, and the mobile terminal can identify a target touch signal from a plurality of touch signals so as to acquire a control instruction corresponding to the target touch signal. The control instruction may be generated by the mobile terminal, or the mobile terminal reads from a locally pre-stored control instruction, and the specific details are not limited as long as the corresponding control instruction can be obtained by external touch. For example, when a user clicks a touch button for configuring the in-vehicle device, the mobile terminal acquires a configuration instruction. When a user clicks a touch button of software of the upgrading vehicle-mounted equipment, the mobile terminal acquires an upgrading instruction. When a user clicks a touch button for acquiring video data, the mobile terminal acquires an instruction for requesting to acquire the video data. The user can click the voice control button to input voice to the mobile terminal, and the mobile terminal can recognize the semantic meaning of the voice and acquire a corresponding control instruction according to the semantic meaning. The control buttons may include a configuration button, an upgrade button, a button for acquiring video data, a button for turning on and off the in-vehicle device, and the like.
Another portion of the control interface of the APP may present real-time video data for the in-vehicle device. After clicking the part of the interface, the video recorded in real time by the vehicle-mounted equipment can be acquired and played, or one or more frames in the video recorded in real time can be acquired. The control interface through APP presents real-time video data of the vehicle-mounted device, so that a user can observe the inconvenient scene observed through naked eyes conveniently, and the user can be helped to perform operations such as adjusting the angle of the camera. The interface of the part can also be used for playing the recorded video of the vehicle-mounted equipment acquired by the mobile terminal.
In step 140, after the connection is successfully established, if a control instruction from the mobile terminal is received through the connection, a corresponding control operation is executed according to the control instruction.
And after the mobile terminal acquires the control instruction, the control instruction is sent to the vehicle-mounted equipment through the connection between the vehicle-mounted equipment and the mobile terminal. After the vehicle-mounted equipment receives the control instruction sent by the mobile terminal through the connection, the vehicle-mounted equipment can firstly identify the control instruction, acquire the type of the control instruction and execute the control operation corresponding to the control instruction according to the type of the control instruction.
The control instruction may include a configuration instruction, an upgrade instruction, a video data acquisition instruction, and the like. In an embodiment, referring to fig. 5, when the control command is a command for acquiring video data, the step of performing the corresponding control operation according to the control command may include the following steps 141 to 144.
In step 141, a video data list is sent to the mobile terminal according to the instruction for acquiring video data, so that the mobile terminal identifies the identifier of the target video data to be acquired from the video data list after receiving the video data list.
When the vehicle-mounted equipment receives an instruction of acquiring video data from the mobile terminal, a video data list is acquired, wherein the video data list can contain identifications of all video data in the vehicle-mounted equipment, and the identification of the video data can be the time of recording the video data.
After the mobile terminal receives the video data list through the connection between the vehicle-mounted equipment and the mobile terminal, the video data list can be displayed on the control interface, and therefore a user can select the identification of the target video data to be acquired from the video data list. And after acquiring the identifier of the target video data selected by the user, the mobile terminal sends the identifier of the target video data to the vehicle-mounted equipment through the connection.
In step 142, receiving the identification of the target video data sent by the mobile terminal through the connection.
In step 143, after receiving the identifier of the target video data through the connection, the target video data is searched according to the identifier.
After the vehicle-mounted equipment receives the identification of the target video data, the corresponding target video data is searched in all the stored video data according to the identification of the target video data.
In step 144, the target video data is transmitted to the mobile terminal through the connection.
In one embodiment, after the vehicle-mounted device successfully sends the target video to the mobile terminal, the vehicle-mounted device can send prompt information to the mobile terminal through the connection between the vehicle-mounted device and the mobile terminal.
According to the control method of the vehicle-mounted device, the connection between the vehicle-mounted device and the mobile terminal is established through the wifi module accessed by the vehicle-mounted device, so that the mobile terminal can send a control instruction to the vehicle-mounted device through the connection to control the vehicle-mounted device. Can know when controlling the mobile unit, only need the mobile unit access wifi module can, the operation is fairly simple, required external equipment is than less to wifi module and mobile terminal conveniently carry, and the user of being convenient for carries, can promote user experience.
