detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The present invention provides a remote control control method based on the Android system. Referring to FIG. 1 , in an embodiment, the Android remote control control method includes:

S10, initializing the remote control's touchpad and Bluetooth module, and controlling the remote control to connect to the controlled device;

In this embodiment, the touch panel and the bluetooth module of the remote controller are initialized, that is, the touch panel and the bluetooth module of the remote controller are restored to an initial state, and the Bluetooth module is used to control the remote controller to establish a Bluetooth connection with the Bluetooth system of the controlled device. .

S20, real-time monitoring the sampling data of the remote control touch panel and the time value of the timer;

Preferably, the timer is a 32-bit timer, and the clock period is 1 millisecond, that is, the timing unit of the 32-bit timer is 1 millisecond. That is to say, when the current time data of the remote controller is 100, that is, the remote controller is powered on until the current time interval is 100 milliseconds, thereby enabling the remote controller to accurately record the time under the current touch operation and the touch operation. The time interval between the two ensures the accurate collection of the touch information of the remote control touch panel and the realization of the subsequent remote control function.

In this embodiment, the sampling data includes a touch trajectory and/or a touch distance, and combined with the collected time value of the touch panel timer, the touch speed can be calculated and analyzed.

S30. The sampled data and the time value are encapsulated into a Bluetooth HID private protocol data packet and sent to the controlled device through the Bluetooth module, so that the controlled device analyzes the operation instruction input by the user according to the sampled data and the time value.

Specifically, when it is determined that the remote controller has a touch operation, the sampling data and the time value of the remote control touch panel are encapsulated into a Bluetooth HID proprietary protocol data packet, and the data packet is sent to the controlled by the Bluetooth module of the remote controller. The Bluetooth system of the device is configured to enable the controlled device to analyze and calculate the sampled data and the time value according to the received data packet, thereby identifying the touch information of the user.

It should be noted that the data packet includes sampling data and a time value, where the sampling data includes a Bluetooth HID private protocol encoding, a touch action encoding, a touch action horizontal coordinate encoding, and a touch action vertical coordinate encoding. The data packet is a 10-byte data packet, including one byte of Bluetooth HID proprietary protocol data encoding, one byte of touch action encoding, two bytes of touch action horizontal coordinate encoding, two bytes of Touch action vertical coordinate coding, and four bytes of timer time value data; thereby enabling the data packet to successfully bypass the Bluetooth HID standard protocol, and packaging the sampling data and time value of the Bluetooth touch remote controller into HID private The protocol data packet is sent to the controlled device, and the sampled data and the time value are analyzed and operated by the controlled device. That is to say, the Bluetooth touch remote controller is only responsible for acquiring, encapsulating and transmitting the touch information, and does not need to analyze and calculate the touch information, thereby greatly reducing the processing load of the Bluetooth touch remote controller CPU, and simplifying the Bluetooth touch remote control. The processing steps of the device further enable the Bluetooth touch remote control to acquire and process complex gestures, and also improve the processing speed of the Bluetooth touch remote controller.

The above-mentioned touch action code can be defined as 1 for pressing, 2 for sliding, and 3 for lifting.

It should be noted that the Android-based controlled device in this embodiment includes a BlueDroid process including a BlueDroid, an EventThread, and a touch point ring buffer, and an Input process including an EventHub and an InputReader. When the Bluetooth touch remote controller sends the data packet to the controlled device, the BlueDroid receives the data packet, and stores the data packet into a touch point ring buffer, and at the same time, the EventThread Reading the data packet, and reducing the read points into a finger sliding curve in chronological order, analyzing and calculating a touch trajectory from a vector speed and a motion trajectory, identifying a touch gesture, and then converting the touch gesture into an Android system Standard Input Key value, the Input Key value is written to the Input device node, then the Input process will immediately read and broadcast to the corresponding APP for processing.

Further, referring to FIG. 2, based on the foregoing embodiment, in the embodiment, the foregoing step S30 further includes:

S31. Determine, according to the touch action code, whether the touch operation is completed.

S32. If yes, the sampled data and the time value are encapsulated into a Bluetooth HID proprietary protocol data packet and stored in the Bluetooth module FIFO buffer;

S33. The Bluetooth module sends the stored Bluetooth HID private protocol data packet to the controlled device, so that the controlled device analyzes an operation instruction input by the user according to the sampled data and the time value.

Specifically, it is determined whether the touch operation is completed according to the touch action code in the monitored sample data, that is, whether the touch action is raised by the touch action code; if yes, determining that the touch operation is completed, the acquired sample data and time will be monitored. The value is encapsulated into a Bluetooth HID proprietary protocol packet and stored in the Bluetooth module FIFO buffer. It should be further noted that the touch action is performed within a preset time period, that is, whether a raised touch action is determined within a preset time period of the timer, and a single time is acquired within the preset time period. The touch action is lifted twice or the touch action is lifted twice, and then it can be judged whether it is a click operation or a double click operation to realize different operation functions.

The FIFO buffer is a first-in first-out buffer, that is, data is sequentially written, and data is sequentially read. For example, the first written data is first read. In this embodiment, the FIFO buffer can buffer continuous data to prevent data loss during storage operations, avoid frequent bus operations, reduce the processing load of the remote controller CPU, and allow the remote controller system to perform DMA. Operation greatly improves the data transmission speed.

The Bluetooth module of the remote controller sends the stored Bluetooth HID private protocol data packet to the controlled device, so that the controlled device decodes the data packet, and analyzes the user input operation according to the received sampling data and time value. instruction.

It should be noted that when the touchless operation is determined according to the sampling data of the touch panel, that is, the corresponding touch motion code is not acquired, the sampled data and the time value that have been acquired are discarded, and the sampling data of the touchpad of the remote controller is re-monitored. The time value of the timer until the touch operation is determined according to the reacquired touch action code, and the sampled data and the time value are encapsulated into a Bluetooth HID proprietary protocol data packet and stored in the Bluetooth module FIFO buffer to ensure subsequent operation functions. achieve.

In this embodiment, a specific implementation step of determining whether there is a touch operation according to the touch action code in the sample data is further proposed, that is, the remote control control method based on the Android system acquires the remote control touch pad by one or more times. Sampling data and time value of the timer until it is determined that there is a touch operation, and the sampled data and the time value are encapsulated into HID private protocol data packets and sent to the controlled device for causing the controlled device of the Android system to receive the data according to the received data. The packet analyzes and calculates the sampled data and the time value, thereby identifying the touch information and ensuring effective operation of the user's finger touch.

Further, referring to FIG. 3, based on the foregoing embodiment, in the embodiment, the remote control method based on the Android system further includes:

S40, obtaining the touch information of the remote control opening key, and determining whether the remote control opening key is long pressed, and if so, controlling the remote control to be turned off.

Specifically, when the Bluetooth touch remote controller completes the sending of the data packet, it is determined whether the remote control open key is long pressed, and when it is determined that the remote control open key is long pressed, the remote control is controlled to be turned off. By controlling the remote control to turn off in time, it is possible to avoid erroneous operation caused by accidental touch of the remote controller, and also save operating power consumption of the remote controller.

It can be understood that the open key of the remote controller can be a physical button or a touch button, and the switch key is electrically connected to the battery of the remote controller.

In this embodiment, the remote control can be controlled to be turned off by acquiring the long press information of the remote control opening key; it should be noted that the opening key of the remote control can be, but is not limited to, only turning off the remote control, and obtaining the key of the remote control. Different touch information can control the remote control to achieve different functions. For example, the double-click information of the open key is used to control the remote controller to enter a sleep state or release the sleep state.

Alternatively, by acquiring different key touch information, the controlled device can be controlled by the remote controller to implement different functions. For example, in an embodiment, by acquiring the click information of the key, the controlled device can be controlled by the remote controller to implement the pause function or the unsuspend function; in another embodiment, by acquiring the double-click information of the key open, The controlled device can be controlled by the remote controller to implement the function of determining the current operation.

It should be noted that when it is judged that the remote control switch key is not long pressed, the process returns to the real-time monitoring of the sampling data of the remote control touch panel and the time value of the timer, and the sampled data and the time value are encapsulated into the Bluetooth HID private protocol data. The package is sent to the controlled device through the Bluetooth module, and it is judged again whether the remote control opening key is long pressed; until it is judged that the remote control opening key is long pressed, the remote control is controlled to be turned off.

It can be understood that the remote controller is controlled to be shut down by judging whether the remote control key is pressed long or not; the user's operation intention is determined by acquiring the key touch information of the remote controller, and then different actions are performed to implement different functions. In this embodiment, the long push key is defined as controlling the remote control to be turned off, that is, only when the touch operation of the user long presses the key is collected, the remote controller is turned off, and when the touch operation of the long press key is not collected, It can be considered that the user does not intend to turn off the remote controller, and then continues to acquire the sampling data of the remote control touch panel and the time value of the timer, and performs corresponding implementation steps to ensure that the user's gesture touch operation can be recognized in time, and the gesture touch operation recognition is improved.
