Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms referred to in this application are explained first:
HID: human Interface devices, are devices that interact directly with a person, such as keyboards, mice, joysticks, and the like. However, the HID device does not necessarily need to be human interface, as long as the devices complying with the HID class specification are HID devices. The exchanged data is stored in a structure called report (report) and the firmware of the device must support the format of the HID report. The host sends and requests the report in control and interrupt transmission to send and receive data. The format of the report is very flexible and can process any kind of data. The HID device in this application refers to a device capable of interacting with a person via bluetooth.
The hidraw device node is a node created in the kernel.
And UHID node: the method is characterized in that a Bluetooth protocol stack and a kernel are interactive interfaces, and for the HID of the Bluetooth, after the intelligent device is connected with the Bluetooth, the service of the detected HID can be transmitted to a kernel through a UHID node. Specifically, the bluetooth protocol stack writes data to a/dev/UHID node (i.e., a UHID node), and the kernel acquires information through the UHID node.
kernel: operating system kernel the operating system kernel refers to the core part of most operating systems. It consists of those parts of the operating system that are used to manage memory, files, peripherals, and system resources. The operating system kernel typically runs processes and provides inter-process communication.
ue vent: user space event, a user space (i.e., application space) event, is a mechanism for communicating between kernel space and user space. I.e. at a certain moment a certain event is triggered and notified to the user space. Mainly for hot plug events (hotsplug). The uevent can be used for general power notification, usb plug notification, headset plug notification, and the like.
And (3) ue ventd: a process in user space for creating a hidraw device node.
The method for processing the external device access of the intelligent device is suitable for creating a hidraw device node in a kernel when the external device is accessed to the intelligent device, so that an application program can successfully open an application scene in which the hidraw device node reads data. The intelligent device can be an intelligent television or an intelligent mobile terminal, and the intelligent mobile terminal can be a smart phone, a tablet computer and the like. The external device may be a bluetooth remote control. For example, when the bluetooth of the smart television is turned on and the bluetooth remote controller is connected, the device information of the bluetooth remote controller is transmitted to the kernel through the UHID node, the kernel generates a ue event and reports the ue event to the ue of the application space, the ue creates a hidraw device node, and notifies the application program after the creation is completed, so that the application program can turn on the hidraw device node to read corresponding data.
Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the following examples, "plurality" means two or more unless specifically limited otherwise.
The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Aiming at the situation that the speech recognition of the smart television still has a certain failure rate in the prior art, through diligent research and analysis, the reason that part of speech recognition fails is caused by the failure of the application program to open the hardaw equipment node. Research shows that the current process of accessing the Bluetooth remote controller to the smart television is as follows:
fig. 1 is a schematic diagram of a general process for accessing a bluetooth remote controller to a smart television. Wherein the application may be a flyover. When a Bluetooth switch of the intelligent television is turned on, a Bluetooth function of the intelligent television is turned on, and a Bluetooth remote controller is connected, a device _ create is used in a kernel to report a uevent event for creating a hidradew device node, an application program (flying) and the uevent both receive the uevent event, the uevent creates the hidradew device node after receiving the event, the application program (flying) opens the hidradew device node after receiving the event, data is read if the opening is successful (Y), the application program (flying) and the uevent exit if the opening is failed (N), but the uevent does not complete creating the hidradew device node if the flying has occurred probabilistically, so that the problem of probabilistically opening the hidrade device node occurs, and voice recognition failure occurs.
In order to solve the problem that the application program may fail to open the hardraw device node, thereby causing a failure in speech recognition, embodiments of the present application provide an improved processing method to solve the problem.
Example one
The embodiment provides a processing method for accessing an external device of an intelligent device, which is used for ensuring that an application program can successfully open a hardraw device node corresponding to the external device and read data in the hardraw device node when the external device accesses the intelligent device. The execution subject of this embodiment is the processing of the external device access of the intelligent device, and the apparatus may be provided in the intelligent device. The intelligent device can be an intelligent television, an intelligent mobile phone, a tablet computer and the like
As shown in fig. 2, a schematic flow chart of a processing method for accessing an external device of an intelligent device provided in this embodiment is shown, where the method includes:
step 101, after the hidraw device node corresponding to the external device is created through the uevantd process, sending a message that the hidraw device node is created to the application program of the application space through the uevantd process.
Specifically, after the ueventd process creates the hidraw device node corresponding to the external device, a message that the hidraw device node is created can be sent to the application program in the application space, so as to notify the application program that the hidraw device node is created.
And step 102, after the application program receives the message that the creation of the hidraw device node is completed, the application program executes corresponding operation on the hidraw device node.
Specifically, the uevent event generated by the kernel for creating the hidraw device node is not reported to the application program any more, but the uevent notifies the application program after the creation is completed. And after receiving the message of completing the creation of the hidraw device node, the application program executes the operations of opening, reading and the like on the hidraw device node. The situation that the ueven is not created completely when the application program is about to open the hidraw device node is avoided.
After the creation of the hidraw device node is completed, the voice data input by the user through the external device is written into the hidraw device node of the kernel, and when the application program needs to use the voice data, the voice data is read from the hidraw device node and is subjected to voice recognition, so that the semantics of the user are obtained, and corresponding services are provided for the user.
Alternatively, the ueven can communicate with the application by creating a socket with the application.
The specific process of interprocess socket communication is as follows:
the method comprises the steps of ueventd and application program, wherein the ueventd is used as a server, and the application program is used as a client.
(a) Server terminal
First, the server process creates a socket by calling the socket by the system, which is a file description-like resource allocated to the server process by the system and cannot be shared with other processes.
The server process then names the socket using the system call bind and then begins waiting for the client to connect to the socket.
The system then calls listen to create a queue and use it to deposit incoming connections from the client.
Finally, the server accepts the client's connection by making a system call accept, which creates a new socket that is different from the original named socket, which is only used for this particular client to communicate, and the named socket (i.e., the original socket) is reserved to continue processing connections from other clients.
(b) Client terminal
The socket-based client application first calls the socket to create an unnamed socket and then calls the connect to the server using the server's named socket as an address.
Once the connection is established, the communication of two-way data can be accomplished with sockets as with the underlying file descriptors.
The way of communication between processes by creating a socket is the prior art, and is not described herein again.
According to the processing method for external device access of the intelligent device, after the firmware process creates the hidrade device node corresponding to the external device, the application program is notified of the message that the creation is completed, and after the application program receives the message that the creation of the hidrade device node is completed, the application program executes the operations of opening the hidrade device node to read data and the like, so that the application program is ensured not to fail to open the hidrade device node, the technical problems that the intelligent television in the prior art has weak local voice recognition capability in a network-disconnected environment and the recognition rate is reduced when continuous control is performed are solved, and the success rate of voice recognition is effectively improved.

And step 2012, creating a corresponding hidraw device node according to the device information of the external device through a ueventd process.
Specifically, when the external device is accessed, the kernel reports a uevent event for creating the hidraw device node, and the upper layer uevent receives the uevent event and then creates the hidraw device node in the dev.
Optionally, before step 2011, the method further comprises:
step 2021, obtaining the device information of the external device through the UHID node, and transmitting to the kernel.
And step 2022, generating a corresponding event by kernel, and reporting to the uevent process.

the method comprises the steps of ueventd and application program, wherein the ueventd is used as a server, and the application program is used as a client.
(a) Server terminal
First, the server process creates a socket by calling the socket by the system, which is a file description-like resource allocated to the server process by the system and cannot be shared with other processes.
The server process then names the socket using the system call bind and then begins waiting for the client to connect to the socket.
The system then calls listen to create a queue and use it to deposit incoming connections from the client.
Finally, the server accepts the client's connection by making a system call accept, which creates a new socket that is different from the original named socket, which is only used for this particular client to communicate, and the named socket (i.e., the original socket) is reserved to continue processing connections from other clients.
(b) Client terminal
The socket-based client application first calls the socket to create an unnamed socket and then calls the connect to the server using the server's named socket as an address.
Once the connection is established, the communication of two-way data can be accomplished with sockets as with the underlying file descriptors.
