Description

Data sending method and device, electronic equipment and storage medium

Technical Field

The present application belongs to the field of communications technologies, and in particular, to a data transmission method, an apparatus, an electronic device, and a storage medium.

Background

In the existing data transmission technology, in order to transmit target data from a transmitting end to a receiving end, a specific modulation mode is often adopted to modulate the target data and transmit the modulated target data to the receiving end. The modulated target data may use waveforms such as sine waves or square waves with the same period to distinguish bit 1 and bit 0, specifically, bit 1 and bit 0 are distinguished by different duty ratios (DutyRatio) in the same period, where a duty ratio refers to a proportion of a high level in one period. For example, in an actual application scenario of the infrared remote controller, in order to send target data corresponding to a key to a target device, processing from a key electrical signal to an infrared light signal is generally implemented based on application layer control of a single chip or an operating system, so that the target data corresponding to the key is modulated into an infrared light signal with a specific waveform and sent to the target device.

However, when target data is transmitted based on the existing data transmission method, the operation of transmitting the target data is often forced to be interrupted due to an emergency, so that the target data is abnormally transmitted or failed, and the data transmission effect is poor. For example, when an application layer based on an android system sends infrared signal data, because the application layer often schedules a system kernel, an operation of sending the infrared signal data is forced to be interrupted, and a waveform of the sent infrared signal data is abnormal, so that the infrared signal data is failed to be sent. Therefore, the existing data transmission method cannot better ensure that the target data transmission operation continues to be completed, which often causes the waveform of the transmitted target data to be abnormal, resulting in poor data transmission effect.

Referring to fig. 1, fig. 1 is a schematic flow chart of a data transmission method according to an embodiment of the present application. An execution main body of the data sending method in this embodiment is an electronic device, an operating system based on a linux kernel is configured on the electronic device in advance, and a sending component is further arranged on the electronic device and used for the operating system to drive and control sending of target data. As shown in fig. 1, the data transmission method of the present application may include:

s101: and monitoring a preset event for transmitting target data to the target equipment.

In step S101, the target device is a device controlled to operate by the electronic device.

And the target data is data information which is formed by the electronic equipment according to the preset event and is used for controlling the target equipment to operate.

The target device may perform a preset operation action according to the received target data. For example, when the electronic device monitors the preset event, target data for controlling the target device to stop operating is sent to the target device, and the target device may execute an action for stopping the operation of the target device according to the target data.

The preset event is an operation event used for describing that a user triggers the target data to be sent to the target device on the electronic device.

The method comprises the steps of receiving a trigger event input by electronic equipment in real time based on an application layer of an operating system configured in advance in the electronic equipment, matching the trigger event with a preset event, determining that the preset event used for sending to target equipment exists if matching is successful, and obtaining target data according to the preset event.

In an 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. An android operating system is pre-configured in the infrared remote controller, 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. And if the key code is received, matching the key code with a preset key code, if the key code is successfully matched, determining that the infrared event exists, converting the key code to obtain target data to be sent, if the key code is successfully matched, obtaining code value data, wherein the code value data is the target data sent to the intelligent television by the infrared remote controller, and if the key code is successfully matched, the code value data is shutdown data corresponding to a shutdown key code.

In an example, the preset event is any event in a preset event list, that is, whether a trigger event exists is monitored based on an application layer of an operating system configured in advance 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 trigger event exists, the preset event list for sending target data to a target device is determined to be monitored.

In an example, based on an application layer of an operating system configured in advance in an electronic device, a trigger event record list is periodically read one by one, the read trigger event is matched with the preset event, and if the matching is successful, it is determined that the preset event for sending to a target device exists.

S102: when the preset event is monitored, locking cache resources 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 resources are 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 program Framework (FWK), a system operation layer and the linux kernel layer, and the layers communicate with one another through software interfaces.

The application layer may include a series of application packages, and the application packages may include one or more of short messages, calendars, cameras, videos, navigation, calls, keyboards and other applications.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program 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 comprises one or more of a view system, a content provider, a resource manager, a notification manager, and an activity manager.

Wherein the view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and the like. The view system may be used to build applications such that the display interface of the electronic device may be comprised of one or more views. For example, the display interface including the short message notification icon may include a view displaying text and a view displaying pictures, and may include a display interface including a keyboard icon.

The Content Providers (Content Providers) allow an application to access data of another application (e.g. a contact database) or to 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 reminder information in a status bar of the electronic device.

The Activity Manager (Activity Manager) is used to manage the application lifecycle and provide the usual navigation fallback functionality.

The system layer may include a plurality of functional modules. For example: a sensor service module, a physical state recognition module, a three-dimensional graphics processing library (e.g., OpenGL ES), and the like.

The sensor service module is used for monitoring sensor data uploaded by various sensors in a hardware layer and determining the physical state of the electronic equipment.

In an example, the system layer may further include: the surface manager is used to manage the display subsystem and provide seamless merging of 2D and 3D layers for multiple applications.

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 the corresponding target data are sent to the linux kernel through an application layer of the operating system, when the linux kernel receives the preset event, the preset service thread is enabled through the linux kernel, and then the cache resource is locked from the operating system through the preset service thread according to the size of the target data, so as to wait for the target data to be cached to the cache resource continuously. And the locking time of the cache resource is from the locking of the operating system by the preset service thread to the complete transmission of the target data to the target equipment.

In order to enable the preset service thread to continuously run without being interrupted by the scheduler of the operating system, so that target data can be completely sent to a target device without delay, the priority of the preset service thread is the highest priority, and the scheduling policy is set as a non-real-time scheduling policy (FiFo).

In an example, the target data is code value data corresponding to a key code of the infrared remote controller. And when an infrared event is monitored, sending the infrared event and code value data corresponding to the infrared event to a linux kernel through an application layer of the operating system.

And when the infrared event is received by the linux kernel, the preset service thread is started, the 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 into the cache resource.

And when the code value data exists in the cache resources, the code value data is sent to the target equipment through the preset service thread.

In an example, when the target data is completely cached in the cache resource, the target data is read from the cache resource and sent to the target device through the preset service thread, and after the target data is sent to the target device, the locked cache resource is released.

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, a sending component on the electronic device is called, and the target data is sent to the target device based on the electric signal.

Illustratively, the code value data corresponding to the infrared event is continuously read from the cache resource through the preset service thread, an electrical signal is generated according to the code value data, an infrared emission tube on the electronic device is called at the same time, and an optical signal is sent to the target device based on the electrical signal, so that the code value data is sent to the target device, for example, the optical signal is sent to a smart television.

Specifically, the target data includes an address code, an address bar code, a command code, and a command bar code, where the address code and the command code are first phase data, and the address bar code and the command bar 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 bar code and the command bar code are identified as second phase data, and the electric signal is generated by 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.

And controlling to generate 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.

Illustratively, the target data is sequentially configured as an address code, an address complement, a command code, and a command complement, 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 anti-code is 000000, the command code is 11111111, and the command anti-code is 000000.

And the preset service thread generates high and low level signals according to the sequence control of the data formed in the target data. If an address code or a command code is sent, the preset service thread drives the gpio port to set a high level, keep the high level for 0.56ms, set a low level again, and keep the low level for 1.68ms, so as to modulate and obtain a data waveform corresponding to the address code or the command code, send the modulated and obtained corresponding data waveform to a target device through a sending component which is arranged on the electronic device and connected with an output port (the gpio port), and then the target device analyzes target data according to the received data waveform. Or when the address code reversal or the command code reversal is sent, the preset service thread drives the gpio port to set a high level, keep the high level for 0.56ms, then set the low level, keep the low level for 0.56ms, so as to modulate and obtain a data waveform corresponding to the address code reversal or the command code reversal, and send the modulated corresponding data waveform to the target equipment through a sending component which is arranged on the electronic equipment and connected with an output port (the gpio port), and then the target equipment carries out target data analysis according to the received data waveform.

In an example, the sending component is an infrared transmitting tube, and the preset service thread controls and generates a high-low level signal according to the first phase data and the second phase data in the target data, so as to drive the infrared transmitting tube to operate, thereby forming a specific optical signal to be sent to the target device, and sending the target data to the target device.

In an example, in order to facilitate a target device to better recognize and receive the target data, the preset service thread controls to generate a high-low level signal to drive the sending component to operate according to the first phase data and the second phase data in the target data, so that before the target data is sent to the target device, the preset service thread generates a guide high-low level signal to drive the sending component to operate according to a guide code of a first preset length, and sends guide identification data to the target device. The pilot code is first phase data.

Illustratively, the boot code is 1111111111111111. Before the target data is sent, the preset service thread drives the gpio port to set a high level for 9ms, set a low level for 4.5ms, and send the data waveform corresponding to the pilot code obtained through modulation to the target device through a sending component which is arranged on the electronic device and connected with an output port (the gpio port).

In an example, in order to facilitate a target device to better recognize that the target device stops receiving 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 sending component to run, so that after the target data is sent to the target device, the preset service thread generates a stop electrical signal according to a stop code of a second preset length to drive the sending component to run, and sends stop identification data to the target device. The stop code is second phase data.

Illustratively, the stop code is 0000. After the target data are all sent to the target equipment, the preset service thread drives the gpio to set a high level according to the stop code, keeps the high level for 0.56ms, and sets the high level to a low level, so that a data waveform corresponding to the pilot code obtained through modulation 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).

In an example, the target data includes an address code, an address inverse, a command code, and a command inverse, wherein the address code, the address inverse, the command code, or the command inverse 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.

Illustratively, the target data is sequentially configured as an address code, an address complement, a command code, and a command complement, 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, address code 11110000, address code violation 110000, command code violation 11111000, and command code violation 111000.

And the preset service thread generates high and low level signals according to the sequence control of the data formed in the target data.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
