In the existing data transmission technology, in order to send target data from a transmitting end to a receiving end, a specific modulation mode is adopted to modulate the target data and then transmit the target data to the receiving end. The modulated target data adopts waveforms such as sine waves or square waves in the same period to distinguish the bit 1 from the bit 0, specifically, different Duty ratios (Duty Ratio) in the same period are used to distinguish the bit 1 from the bit 0, and the Duty Ratio refers to the proportion of high level in one period. For example, in an actual application scenario of an infrared remote controller, in order to send target data corresponding to a key to a target device, processing from an electrical signal of the key to an infrared signal is generally implemented based on application layer control of a single-chip microcomputer or an operating system, so that the target data corresponding to the key is modulated into an infrared signal with a specific waveform and sent to the target device.
However, when transmitting the target data based on the existing data transmission method, the operation of transmitting the target data is often forced to be interrupted due to an emergency, which results in abnormal or failed transmission of the target data, and thus the data transmission effect is poor. For example, when an application layer based on an android system transmits infrared signal data, the application layer is often scheduled for a system kernel, so that the operation of transmitting the infrared signal data is forced to be interrupted, and the waveform of the transmitted infrared signal data is abnormal, thereby causing failure in transmitting the infrared signal data.

Referring to fig. 1, fig. 1 is a flowchart of a data transmission method according to an embodiment of the present application. The execution main body of the data transmission method in this embodiment is an electronic device, an operating system based on a linux kernel is preconfigured on the electronic device, and a transmission component is further arranged on the electronic device for driving and controlling the operating system to transmit target data. As shown in fig. 1, the data transmission method of the present application may include:
s101: and monitoring a preset event for sending target data to the target device.
In step S101, the target device is a device controlled to operate by the electronic device.
The target data is data information which is formed by the electronic equipment according to the preset event and used for controlling the operation of the target equipment.
The target device can execute a preset operation action according to the received target data. For example, when the electronic device monitors the preset event, the electronic device sends target data for controlling the target device to stop running to the target device, and the target device can execute an action for stopping the running of the target device according to the target data.
The preset event is an operation event used for describing that a user triggers on the electronic equipment to send the target data to the target equipment.
Based on an application layer of a pre-configured operating system in the electronic equipment, receiving a trigger event input by the electronic equipment in real time, matching the trigger event with a preset event, if the matching is successful, determining that the preset event for sending to the target equipment exists, and acquiring target data according to the preset event.
For example, when the preset event is an infrared event, the electronic device is an infrared remote controller, and the target device is an intelligent television. And the infrared remote controller is preconfigured with an android operating system, and whether a key code sent by a keyboard controller of the infrared remote controller is received or not is monitored in real time based on an application layer of the android operating system. If the key code is received, the key code is matched with a preset key code, if the key code is successfully matched, the existence of the infrared event is determined, target data to be transmitted is obtained through conversion according to the key code, for example, code value data is obtained through conversion, and the code value data is target data transmitted to the intelligent television by the infrared remote controller, for example, shutdown data corresponding to a shutdown key code.
In an example, the preset event is any event in a preset event list, that is, based on whether a trigger event exists in an application layer of a preconfigured operating system in the electronic device, if the trigger event exists, the trigger event is matched with the preset event recorded in the preset event list, and if the matching is successful, it is determined that the preset event list for sending target data to the target device is monitored.
In an example, based on an application layer of an operating system preconfigured in the electronic device, periodically reading a trigger event record list one by one, matching the read trigger event with the preset event, and determining that the preset event for sending to the target device exists if the matching is successful.
S102: when the preset event is monitored, locking a cache resource from the operating system through a preset service thread in the linux kernel; the cache resource is used for caching target data corresponding to the preset event.
In step S102, the preset service thread is a kernel thread in the linux kernel. The cache resource is a memory in the electronic device for temporarily storing programs and data, and can be managed and configured by the operating system. The operating system is a computer program that manages computer hardware and software resources in the electronic device.
The operating system is divided into four layers, namely an application program layer, an application framework layer (FWK), a system running layer and the linux kernel layer, and the layers are communicated through software interfaces.
The application layer may be a series of application packages, and the application packages may include one or more of short messages, calendars, cameras, videos, navigation, communication, keyboards, and other application programs.
The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer may include some predefined functions, for example, functions for receiving events sent by the application framework layer.
The application framework layer includes one or more of a view system, a content provider, a resource manager, a notification manager, and an activity manager.
The view system comprises visual controls, such as a control for displaying characters, a control for displaying pictures and the like. The view system may be used to build an application such that a display interface of the electronic device may be composed of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying a picture, and may include a display interface including a keyboard icon.
The content provider (Content Providers) allows applications to access data of another application (e.g., a contact database) or share their own data
The Resource Manager (Resource Manager) provides access to non-code resources such as local strings, graphics and Layout files (Layout files).
The notification manager (Notification Manager) enables an application to display custom hints in a status bar of the electronic device.
The Activity Manager (Activity Manager) is used to manage application lifecycle and provide common navigation rollback functionality.
The system layer may include a plurality of functional modules. For example: sensor service module, physical state recognition module, three-dimensional graphics processing library (e.g. OpenGL ES), etc.
The sensor service module is used for monitoring sensor data uploaded by various sensors of the hardware layer and determining the physical state of the electronic equipment.
The physical state recognition module is used for analyzing and recognizing gestures, faces and the like of a user;
the three-dimensional graphic processing library can be used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.
In an example, the system layer may further include: the surface manager is used to manage the display subsystem and provides a seamless fusion of 2D and 3D layers for multiple applications.
The linux kernel is a layer between hardware and software, and comprises one or more of a display driver, a sending component driver, a flash memory driver, a keyboard driver, power management, a kernel driver, an audio driver, a wireless driver and a camera driver, and is used for driving related hardware of a hardware layer of the electronic device, such as a display screen, an infrared transmitting tube, a sensor and the like.
S103: and sending the target data to the target equipment through the preset service thread.
In this embodiment, when the preset event is monitored, the preset event and corresponding target data are sent to the linux kernel through an application layer of the operating system, and when the linux kernel receives the preset event, the preset service thread is started through the linux kernel, and further, a cache resource is locked from the operating system through the preset service thread according to the size of the target data, so that the target data are waited to be cached to the cache resource continuously. And the locking time of the cache resource is from the locking of the operating system to the complete sending of the target data to the target device by the preset service thread.
In order that the preset service thread can run continuously without being interrupted by a scheduler of the operating system, the target data can be sent to the target device completely and without delay, the priority of the preset service thread is the highest priority, and the scheduling policy is set to be a non-real-time scheduling policy (FiFo).
The target data is code value data corresponding to a key code of the infrared remote controller. When an infrared event is monitored, the infrared event and code value data corresponding to the infrared event are sent to a linux kernel through an application layer of the operating system.
When the infrared event received by the linux kernel is detected, the preset service thread is started, a cache resource is locked from the operating system through the preset service thread according to the size of the code value data, if the size of the code value data is 4 bytes, the cache resource with the size of 4 bytes is locked from the operating system, and the code value data is waited to be cached in the cache resource.
And when confirming that the code value data exist in the cache resource, transmitting the code value data to the target equipment through the preset service thread.
In an example, when the target data is completely cached in the cache resource, reading the target data from the cache resource by the preset service thread, sending the target data to the target device, and releasing the locked cache resource after sending the target data to the target device.
In an example, when the target data transmission is finished, the preset service thread enters a sleep state.
In an example, the target data is continuously read from the cache resource through the preset service thread, an electric signal is generated according to the target data control, and meanwhile, a sending component on the electronic equipment is called, and the target data is sent to the target equipment based on the electric signal.
For example, the preset service thread continuously reads the code value data corresponding to the infrared event from the cache resource, and generates an electric signal according to the code value data control, and meanwhile invokes an infrared transmitting tube on the electronic device to transmit an optical signal to the target device based on the electric signal, so that the code value data is transmitted to the target device, for example, the optical signal is transmitted to the smart television.
Specifically, the target data includes an address code, a command code and a command code, wherein the address code and the command code are first phase data, and the address code and the command code are second phase data.
Specifically, when the target data is continuously read from the cache resource through the preset service thread, the address code and the command code are identified as first phase data, the address counter code and the command counter code are identified as second phase data, and the first phase data and the second phase data are utilized to generate the electric signal; wherein a high level of the electrical signal is used to describe the first phase data and a low level of the electrical signal is used to describe the second phase data.
And controlling and generating a high-low level signal according to the first phase data and the second phase data in the target data through the preset service thread, and driving the sending component to run so as to send the target data to the target equipment.
The order of the target data is exemplified by an address code, a command code, and is represented by 0 or 1, the first phase data is represented by 1, and the second phase data is represented by 0. For example, the address code is 11111111, the address code is 000000, the command code is 11111111, and the command code is 000000.
And the preset service thread generates high-low level signals according to the sequence control of the constituting data in the target data. When an address code or a command code is transmitted, the preset service thread drives the gpio port to set a high level, keep the high level for 0.56ms, and keep the low level for 1.68ms because of being indicated by 1, so that a data waveform corresponding to the address code or the command code is obtained through modulation, the modulated corresponding data waveform is transmitted to target equipment through a transmitting component which is arranged on the electronic equipment and is connected with an output port (gpio port), and then the target equipment analyzes target data according to the received data waveform. Or when the address code or the command code is sent, the preset service thread drives the gpio port to set high level and keep 0.56ms and low level for 0.56ms because of being expressed by 0, so that the data waveform corresponding to the address code or the command code is modulated and obtained, the modulated corresponding data waveform is sent to the target equipment through a sending component which is arranged on the electronic equipment and connected with an output port (gpio port), and then the target equipment analyzes the target data according to the received data waveform.
In an example, the sending component is an infrared sending tube, and the preset service thread is used for controlling to generate a high-low level signal according to the first phase data and the second phase data in the target data, so that the operation of the infrared sending tube is driven, and a specific optical signal is formed and sent to the target device, so that the target data is sent to the target device.
In an example, in order to facilitate the target device to better recognize and receive the target data, the preset service thread controls to generate a high-low level signal according to the first phase data and the second phase data in the target data to drive the operation of the sending component, so that before the target data is sent to the target device, the preset service thread generates a guide high-low level signal according to a guide code with a first preset length to drive the operation of the sending component, and sends guide identification data to the target device. The pilot code is first phase data.
For example, the pilot code is 1111111111111. Before the target data is sent, the preset service thread sets a high level according to the guide code driving gpio port, keeps 9ms, sets the guide code driving gpio port to be low level again and keeps 4.5ms, so that a data waveform corresponding to the modulated guide code is sent to the target device through a sending component which is arranged on the electronic device and is connected with an output port (gpio port).
In an example, in order to facilitate the target device to better identify that the target device stops receiving the target data, the preset service thread generates a high-low level signal according to the first phase data and the second phase data in the target data to drive the operation of the sending component, so that after the target data is sent to the target device, the preset service thread generates a stop electric signal according to a stop code with a second preset length to drive the operation of the sending component, and sends stop identification data to the target device. The stop code is second phase data.
For example, the stop code is 0000. After all the target data are sent to the target device, the preset service thread sets a high level according to the stop code driving gpio, keeps the high level for 0.56ms and sets the high level to be low level, so that a data waveform corresponding to the modulated guide code is sent to the target device through a sending component which is arranged on the electronic device and is connected with an output port (gpio port).
In an example, the target data includes an address code, a command code, and a command code, wherein the address code, the command code, or the command code are each represented by first phase data and second phase data, respectively.
Generating the electrical signal using the first phase data and the second phase data; wherein a high level of the electrical signal is used to describe the first phase data and a low level of the electrical signal is used to describe the second phase data.
The order of the target data is exemplified by an address code, a command code, and is represented by 0 or 1, the first phase data is represented by 1, and the second phase data is represented by 0. For example, the address code is 11110000, the address code is 110000, the command code is 11111000, and the command code is 111000.
And the preset service thread generates high-low level signals according to the sequence control of the constituting data in the target data.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
