Description

A remote controller, controlled device and method for realizing code matching based on Bluetooth broadcast packets technical field

The invention relates to the field of Bluetooth technology, in particular to a remote controller, a controlled device and a method for realizing code matching based on a Bluetooth broadcast packet.

Background technique

With the development of technology, the control of many devices can be controlled by remote controllers, such as smart TVs, wireless mice, various players, smart lamps, etc. There are also many kinds of remote controllers on the market. Such as infrared remote control, RF remote control, Bluetooth remote control and so on.

The remote control is a wireless transmitting device. It encodes the key information through modern digital coding technology and sends it to the receiving end through infrared or other wireless signals. The receiving end converts the received infrared signal or wireless signal into an electrical signal, The processor decodes and demodulates the corresponding instructions to achieve the purpose of controlling the relevant equipment to complete the required operation requirements. Its biggest advantage is that it can also be controlled without close contact with the controlled equipment.

At present, the use of the remote control involves two situations: pass code and pair code. The passcode means that the controlled device does not recognize the remote control ID, and any remote control can control it. Code matching means that after the code matching operation, the controlled device saves the remote control ID. After receiving the command, it checks whether it is sent by the code-matched remote control. The controlled device can only be controlled by the code-matched remote control. The remote control that is paired can prevent interference from other remote controls, and can use multiple sets of remote controls and controlled devices at the same time, so it is more favored.

Now one-way remote control is divided into infrared remote control, RF remote control, etc.; RF remote control is divided into 315MHz, 433MHz, 2.4GHz and other frequency bands, 2.4GHz frequency band remote control is also divided into private protocol remote control, remote control based on Bluetooth broadcast package, etc. ; Among them, the one-way remote control based on the Bluetooth broadcast package is widely used for its advantages of long transmission distance, low power consumption, barrier-free, and support for more complex protocols, but the one-way remote control based on the Bluetooth broadcast package can only The signal is sent in one direction, and a Bluetooth connection cannot be established.

The existing one-way remote control pairing method based on Bluetooth broadcast packet is as follows:

Long press the pairing button, the remote control sends Bluetooth broadcast packets continuously, and the controlled device detects a certain amount of Bluetooth broadcast packets to complete the pairing.

However, the above method has the following disadvantages: because the wireless signal is easily interfered, the controlled devices may not be able to receive all the Bluetooth signals continuously sent by the remote control, and the reception rate is relatively low in some cases of severe interference. If the agreed number of received Bluetooth broadcast packets is relatively large, the detection time will be relatively long. If the agreed number of received Bluetooth broadcast packets is small, the stability will be poor and false triggering will be easy. Therefore, when the one-way remote control based on the Bluetooth broadcast packet adopts the above method to perform code matching, the stability is not high.

SUMMARY OF THE INVENTION

In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a remote controller, a controlled device and a method for realizing code matching based on a bluetooth broadcast packet, so as to improve the reliability of the remote controller's code matching operation based on the bluetooth broadcast packet. .

In order to achieve the above and other purposes, the present invention proposes a remote controller for realizing code matching based on a Bluetooth broadcast packet, on which a code matching key is provided, including:

a key monitoring unit, used to monitor in real time whether the code pair key on the remote control is pressed, and if it is detected that the code pair key is pressed, enter the long-press judgment unit;

The long-pressing judgment unit is used for judging whether the continuous key-pressing time of the code-matching key exceeds the preset code-matching setting time threshold, and if it exceeds the preset code-setting time threshold, the code-matching identification sending unit is entered;

The code matching identification sending unit is used to generate the matching code identification, fill the matching identification identification into the Bluetooth broadcast packet and send it, that is, send the matching code identification in the form of a Bluetooth broadcast packet. If the preset code matching time threshold is not exceeded, Then continue to wait and monitor the code key in real time;

The continuous monitoring unit is used for continuously judging whether the pairing key is kept pressed after the pairing identifier sending unit sends the Bluetooth broadcast packet, and if so, returning to the pairing identifier sending unit to continue to send the bluetooth containing the pairing identifier broadcast packets.

Preferably, when the long-press judging unit determines that the user's continuous pressing time on the code-matching key exceeds the code-matching setting time threshold, the key identifier is changed from a short-press identifier to a long-pressed code-matching identifier. The identifier sending unit fills the long-pressed pairing identifier into the Bluetooth broadcast packet and sends it out.

In order to achieve the above object, the present invention also provides a controlled device for realizing code matching based on a Bluetooth broadcast packet, including:

The bluetooth broadcast packet parsing unit is used to analyze the bluetooth broadcast packet when receiving the bluetooth broadcast packet, and determine whether the bluetooth broadcast packet contains the code matching identification. ;

A code-matching success determination unit is used to determine the remote-controller's code-matching when the number of received Bluetooth broadcast packets containing the code-matching identifier of the same remote control ID is greater than or equal to a preset threshold for the number of Bluetooth broadcast packets for successful code-matching Successful, and save the remote control ID that has been successfully paired.

Preferably, if the received Bluetooth broadcast contains a code pairing identifier, the Bluetooth broadcast packet parsing unit also compares the currently obtained remote control ID with the saved remote control ID with successful code matching, if the currently obtained remote control ID If it already exists in the saved remote control ID with successful code matching, exit the current remote control code matching process.

Preferably, the controlled device further includes a scanning unit for starting the controlled device when it is powered on, starting the scanning of Bluetooth broadcast packets, and starting the Bluetooth broadcast packet parsing unit when a Bluetooth broadcast signal is scanned.

Preferably, when the Bluetooth broadcast packet parsing unit determines that the Bluetooth broadcast packet contains a code matching identifier, it further judges whether the time when the Bluetooth broadcast packet is received exceeds a preset time limit for code matching. If the time threshold is limited, then the remote control ID is obtained according to the Bluetooth broadcast packet and recorded, and when the code matching success determination unit does not exceed the preset time limit for code matching, the received code containing the same remote control ID contains the matching code. When the number of identified Bluetooth broadcast packets is greater than or equal to the threshold of the number of Bluetooth broadcast packets successfully paired, it is determined that the remote control is successfully paired.

In order to achieve the above object, the present invention also provides a method for realizing code matching based on a Bluetooth broadcast packet, comprising the following steps:

Step S1, the remote controller monitors in real time whether the code pair key on it is pressed, and if pressed, then enters step S2;

Step S2, judging whether the continuous pressing time of the pairing key exceeds a preset pairing setting time threshold, and if it exceeds the preset pairing setting time threshold, then fill the pairing identifier corresponding to the pairing key into the Bluetooth broadcast the packet and send it out, and continuously send the Bluetooth broadcast packet containing the pair code identifier under the condition of continuously pressing the code pair key;

Step S3, when receiving the Bluetooth broadcast packet, the controlled device parses the Bluetooth broadcast packet, and determines whether the Bluetooth broadcast packet contains a pairing identifier, and if it contains a pairing identifier, obtains a corresponding remote control according to the Bluetooth broadcast packet. device ID and record it;

Step S4, when the number of times that the controlled device receives the bluetooth broadcast packets with the same remote control ID that contains the code pairing identifier is greater than or equal to the preset threshold of the number of bluetooth broadcast packets that successfully pair codes, then determine that the remote control pair codes. Successful, and save the remote control ID that has been successfully paired.

Preferably, in step S2, when the continuous pressing time of the pairing key exceeds the setting time threshold for pairing, the key identifier is changed from a short-press identifier to a long-pressed pairing identifier, and the long-pressed pairing identifier is changed. The identity is filled into the Bluetooth broadcast packet and sent out.

Preferably, in step S3, the currently obtained remote control ID is compared with the saved remote control ID with successful code matching, if the currently obtained remote control ID already exists in the saved remote control ID with successful code matching, Then exit the code matching process of the current remote control.

Preferably, in step S3, when it is judged that the Bluetooth broadcast packet contains a code matching identifier, it is further judged whether the time when the Bluetooth broadcast packet is received exceeds a preset code matching time limit, and if it does not exceed the code matching time limit Threshold, then obtain the remote control ID according to the Bluetooth broadcast packet and record it, if it exceeds the limit time threshold for code matching, then end the current code matching process; in step S4, when the preset time limit for code matching does not exceed the threshold value, When the number of received Bluetooth broadcast packets with the same remote control ID containing the pairing identifier is greater than or equal to the threshold of the number of Bluetooth broadcast packets successfully paired, it is determined that the remote controller is successfully paired.

Compared with the prior art, a remote controller, a controlled device and a method for realizing code matching based on a Bluetooth broadcast packet of the present invention can effectively prevent the controlled device from performing code matching only within a certain period of time when the controlled device is powered on. The code is incorrectly paired due to interference, and after the time threshold is set by pressing the pairing button for a long time, the button identification is changed from the short-pressing mark to the long-pressing the pairing mark, and a Bluetooth broadcast packet containing the pairing mark is sent. The method of using different identifications with long presses prevents false triggering of the code pairing by short presses. At the same time, after triggering the pairing codes, the remote control terminal continuously sends the Bluetooth broadcast packets, and the controlled device only needs to detect a small number of times that the codes contain the pairing codes. The Bluetooth broadcast packet can complete the code matching, which can ensure the reliability of the code matching operation.

Detailed ways

The embodiments of the present invention will be described below through specific examples and in conjunction with the accompanying drawings, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific examples, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present invention.

Before explaining the present invention, define several concepts involved in the present invention:

Code-matching time limit: The controlled device can accept code-matching operations within a certain period of time after it is powered on. After this time, the code-matching application will not be accepted. This time is the code-matching time limit.

Setting time threshold for code matching: When the remote control performs code matching, it takes a certain period of time to press the code matching key to send the Bluetooth broadcast packet containing the matching code identification. This time is the code matching setting time.

Threshold of the number of Bluetooth broadcast packets for successful code pairing: used to determine the number of Bluetooth broadcast packets containing the code pair identifier that need to be received for successful code pairing.

FIG. 1 is a schematic structural diagram of a remote controller for realizing code matching based on a Bluetooth broadcast packet according to the present invention. As shown in Figure 1, the present invention is a remote controller for realizing code matching based on a Bluetooth broadcast packet, which is provided with a code matching key, including:

The key monitoring unit 101 is used to monitor in real time whether the pairing key on the remote control is pressed. If it is detected that the pairing key is pressed, enter the long-press judging unit 102, otherwise continue monitoring.

In the present invention, the remote controller is a remote controller that contains a Bluetooth chip or an RF chip, and can send a Bluetooth broadcast packet through a Bluetooth broadcast method. The remote controller is provided with a pairing key, which can be a single key, or a pairing key. It can include a combination of multiple keys to form a pairing key, monitor the state of the pairing key, and monitor whether the user presses the pairing key in real time. If it is detected that the user presses the pairing key, the long press judgment unit 102.

Long press the judgment unit 102, for judging whether the continuous pressing time of the code key exceeds the preset code setting time threshold, if it exceeds the preset code setting time threshold, then enter the code matching identification sending unit 103; otherwise, if not If the preset time threshold for pairing is exceeded, continue to wait and monitor the pairing key in real time.

The pairing identification sending unit 103 is used to generate the pairing identification, fill the pairing identification into the Bluetooth broadcast packet and send it, that is, send the pairing identification in the form of a Bluetooth broadcast packet, if the preset pairing setting time threshold is not exceeded , continue to wait and monitor the code key in real time.

In the present invention, the system of the remote controller is preset with a code setting time threshold. When the user starts to press the code key, a short-pressing mark is generated. When the continuous key press time exceeds the set time threshold for the code pairing, the key identifier is changed from a short press identifier to a long-pressed pairing identifier. The above-mentioned Bluetooth broadcast packet is a command sent in a specified format. In addition to the code identification, it also includes the relevant control identification information of the remote control, such as the remote control ID, etc. The remote control ID can be a MAC address or other non-repetitive information identification. . That is to say, when the remote control performs code pairing, when the pair code button is pressed, the Bluetooth broadcast packet containing the code pair identifier will be sent not immediately but after a certain period of time. For setting the time threshold for code matching, the present invention sets the time threshold for code matching, so that the remote controller only fills the long-pressing code-matching logo into the Bluetooth after monitoring the long-pressing of the code-matching key to the preset code-matching setting time threshold. After the broadcast packet is sent out, the long-pressing button in the code-matching operation of the present invention can effectively avoid false triggering caused by short-pressing. Filling the long-press pair code identifier into the Bluetooth broadcast packet and sending it out, this method is more reliable to realize the long-press operation.

The continuous monitoring unit 104 is used for continuously judging whether the pairing key is kept pressed after the pairing identifier sending unit 103 sends the Bluetooth broadcast packet, and if so, returning to the pairing identifier sending unit 103 to send the bluetooth broadcast containing the pairing identifier again Otherwise, return to the key monitoring unit 101 to monitor again and wait for the code key to be pressed.

FIG. 2 is a schematic structural diagram of a controlled device that implements code matching based on a Bluetooth broadcast packet according to the present invention. As shown in Figure 2, a controlled device for realizing code matching based on a Bluetooth broadcast packet of the present invention includes:

The bluetooth broadcast packet parsing unit 210 is used to analyze the bluetooth broadcast packet when receiving the bluetooth broadcast packet, and determine whether the bluetooth broadcast packet contains a code matching identifier, and if it contains a code matching identifier, obtain the remote control ID according to the Bluetooth broadcast packet and assign it Record, if the Bluetooth broadcast packet does not contain a code matching identifier, it is indicated as a Bluetooth broadcast packet other than the code matching, and the Bluetooth broadcast packet is processed for other identifications other than the code matching.

Preferably, if the received Bluetooth broadcast contains a code pairing identifier, the Bluetooth broadcast packet parsing unit 210 also compares the currently obtained remote control ID with the saved remote control ID with successful code pairing. If it exists in the saved remote control ID with successful code matching, it will exit the current remote control code matching process.

The code pairing success determination unit 211 is used to determine that the code pairing of the remote control is successful when the number of received bluetooth broadcast packets containing the code pairing identifier of the same remote control ID is greater than or equal to the threshold of the number of Bluetooth broadcast packets that have successfully paired codes, And save the ID of the remote control that has been successfully matched, and save the ID of the remote control that has been successfully matched to the storage area, so that it will not be lost due to power failure. The remote control ID will be verified every time a control command is received in the future to ensure that it is controlled. The device only performs corresponding operations on the saved remote control ID, and the threshold of the number of Bluetooth broadcast packets for successful code pairing refers to the preset number of Bluetooth broadcast packets containing the code pair identifier that need to be received to judge that the code pair is successful.

Preferably, the present invention is a controlled device that implements code matching based on a Bluetooth broadcast packet, further comprising:

The scanning unit 212 is used for starting the controlled device when it is powered on, starting the scanning of the Bluetooth broadcast packet, and starting the Bluetooth broadcast packet parsing unit 210 when the Bluetooth broadcast signal is scanned.

Preferably, the Bluetooth broadcast packet parsing unit 210, when judging that the Bluetooth broadcast packet contains the code matching identifier, further judges whether the time when the Bluetooth broadcast packet is received exceeds the preset code matching time threshold, if not exceeds the code matching limit. If the time threshold is set, the remote control ID is obtained and recorded according to the Bluetooth broadcast packet. The code-matching time threshold refers to the preset time range within which the controlled device can accept the code-matching operation after power-on, that is, the controlled device is on the After the power is turned on, the code matching operation can only be accepted within the code matching limited time threshold. If this time is exceeded, the code matching application will not be accepted. , when the number of received Bluetooth broadcast packets with the same remote control ID containing the code pairing identifier is greater than or equal to the threshold of the number of Bluetooth broadcast packets successfully paired, it is determined that the remote control is successfully paired.

FIG. 3 is a flow chart of steps of a method for implementing code matching based on a Bluetooth broadcast packet according to the present invention. A method for realizing code matching based on a Bluetooth broadcast packet of the present invention comprises the following steps:

Step S1, monitor in real time whether the code pair key on the remote control is pressed, if pressed, go to step S2, otherwise continue monitoring.

In the present invention, the remote control is a remote control that contains a Bluetooth chip or an RF chip and can send Bluetooth broadcast packets through Bluetooth broadcast. When the code key is pressed, a corresponding code pair identification will be generated. The code pair key can be a single key or a combination of multiple keys to form a code pair key. The state of the code key is monitored, and whether the user presses the key is monitored in real time. Press the pairing key, and if it is detected that the user presses the pairing key, step S2 is entered.

Step S2, judging whether the continuous pressing time of the pairing key exceeds the preset pairing setting time threshold, and if it exceeds the preset pairing setting time threshold, then fill the pairing identifier corresponding to the pairing key into the Bluetooth broadcast packet. And send, that is to say, the code matching identification is sent out in the form of a Bluetooth broadcast packet. If the preset code matching time threshold is not exceeded, continue to wait and monitor the code matching key in real time.

That is to say, the system of the remote control needs to be pre-set with a code setting time threshold. When the user starts to press the code key, a short press mark is generated. When the user continues to press the code key for more than When the time threshold is set, the key identifier is changed from a short-press identifier to a long-pressed pairing identifier, and the long-pressed pairing identifier is filled into the Bluetooth broadcast packet and sent out. The pairing identifier can be a key value or a special identifier. A defined identifier used for code matching. That is to say, when the remote control performs code pairing, when the pair code button is pressed, the Bluetooth broadcast packet containing the code pair identifier will be sent not immediately but after a certain period of time. Set the time threshold for code matching. In the present invention, a Bluetooth broadcast packet refers to a Bluetooth broadcast command sent in a specified format through a Bluetooth broadcast method, and includes control identification information related to a remote control, such as a remote control ID.

In the present invention, by setting the code setting time threshold, the remote controller fills the long-pressed code-pairing identifier into the Bluetooth broadcast packet and sends it out only after monitoring the long-pressing of the code-pairing key to the preset code-pairing setting time threshold. In the invention, the long-pressing of the code-matching key can effectively avoid false triggering caused by short-pressing, so that the code-matching operation is more reliable.

Preferably, in step S2, after the bluetooth broadcast packet is sent, it is continuously judged whether the pairing key is kept pressed, if so, the bluetooth broadcast packet containing the pairing identifier is sent again, otherwise it returns to step S1 to re-monitor and wait for the pairing key to be Press.

Step S3, when receiving the bluetooth broadcast packet, the controlled device parses the bluetooth broadcast packet, and judges whether the bluetooth broadcast packet contains a code-matching identifier, and if it contains a code-matching identifier, obtains the remote control ID according to the bluetooth broadcast packet and records it; The bluetooth broadcast packet does not contain a code matching identifier, and it is indicated as a bluetooth broadcast packet other than the code matching identifier, and the Bluetooth broadcast packet is processed with other identifiers than the code matching identifier.

In the present invention, the controlled device refers to a device that can parse Bluetooth broadcast packets and needs a remote controller to control.

Preferably, in step S3, the currently obtained remote control ID is compared with the saved remote control ID with successful code matching, if the currently obtained remote control ID already exists in the saved remote control ID with successful code matching, Then exit the code matching process of the current remote control.

In step S4, when the number of times that the controlled device receives the Bluetooth broadcast packets containing the code pairing identifier of the same remote control ID is greater than or equal to the threshold of the number of Bluetooth broadcast packets successfully paired, it means that the code pairing of the remote control is successful, and the pairing is saved. The ID of the remote control that has been successfully coded will be saved to the storage area, so that it will not be lost due to power failure, and the remote control ID will be verified each time a control command is received in the future to ensure that the controlled device can only be used for Do the corresponding operation with the saved remote control ID. The threshold of the number of Bluetooth broadcast packets for successful code pairing refers to a preset number of Bluetooth broadcast packets containing a code pair identifier that need to be received to judge that the code pair is successful.

Preferably, before step S3, a method for implementing remote control code matching based on a Bluetooth broadcast packet of the present invention further includes:

Step S2-1, the controlled device is powered on and started, and the Bluetooth broadcast packet scanning is started;

Step S2-2, determine whether the Bluetooth broadcast signal is scanned, if not, continue scanning, otherwise, go to step S3.

Preferably, in step S3, when it is judged that the Bluetooth broadcast packet contains a code matching identifier, it is further judged whether the time when the Bluetooth broadcast packet is received exceeds a preset code matching time limit, and if it does not exceed the code matching time limit Threshold, the remote control ID is obtained and recorded according to the Bluetooth broadcast packet. The code-matching time limit refers to the preset time range within which the controlled device can accept the code-matching operation after power-on, that is, the controlled device is powered on. After that, the code matching operation can only be accepted within the code matching time threshold, and beyond this time limit, the code matching application will not be accepted. The number of Bluetooth broadcast packets with the same remote control ID containing the code pairing identifier is greater than or equal to the threshold of the number of Bluetooth broadcast packets successfully paired, then the remote control is successfully paired.

It can be seen that in the present invention, the controlled device can not perform the remote control code matching operation in real time, and the code matching process should be performed within a certain period of time when the controlled device is powered on. The code can only be matched within the code limit time threshold, and the code matching application will not be accepted at other times, which can effectively prevent the controlled equipment from being interfered with and cause incorrect code matching.

After the time threshold is set by pressing the pairing button for a long time, the key identification is changed from the short-pressing mark to the long-pressing pairing mark, and a Bluetooth broadcast packet containing the pairing mark is sent. The method of using different identifiers for long presses prevents false triggering of the code pairing by short presses. At the same time, after triggering the pairing code, the remote control terminal continuously sends the Bluetooth broadcast packets, and the controlled device only needs to detect a small number of times the bluetooth containing the code pairing identifier.

7. A method for realizing code matching based on a Bluetooth broadcast packet, comprising the following steps:

   Step S1, the remote controller monitors in real time whether the code pair key on it is pressed, and if pressed, then enters step S2;

   Step S2, judging whether the continuous pressing time of the pairing key exceeds a preset pairing setting time threshold, and if it exceeds the preset pairing setting time threshold, then fill the pairing identifier corresponding to the pairing key into the Bluetooth broadcast the packet and send it out, and continuously send the Bluetooth broadcast packet containing the pair code identifier under the condition of continuously pressing the code pair key;

   Step S3, when receiving the Bluetooth broadcast packet, the controlled device parses the Bluetooth broadcast packet, and determines whether the Bluetooth broadcast packet contains a pairing identifier, and if it contains a pairing identifier, obtains a corresponding remote control according to the Bluetooth broadcast packet. device ID and record it;

   Step S4, when the number of times that the controlled device receives the bluetooth broadcast packets with the same remote control ID that contains the code pairing identifier is greater than or equal to the preset threshold of the number of bluetooth broadcast packets that successfully pair codes, then determine that the remote control pair codes. Successful, and save the remote control ID that has been successfully paired.
8. The method for realizing remote control code matching based on a Bluetooth broadcast packet according to claim 7, wherein in step S2, when the continuous pressing time of the code matching key exceeds the code matching setting time threshold, the key is pressed. The identification is changed from the short-press identification to the long-pressed pairing identification, and the long-pressed pairing identification is filled into the Bluetooth broadcast packet and sent out.
9. A method for realizing remote control code matching based on a Bluetooth broadcast packet as claimed in claim 8, characterized in that: in step S3, the currently obtained remote control ID is compared with the saved remote control ID with successful code matching. , if the currently obtained remote control ID already exists in the saved remote control IDs that have been successfully paired, exit the current remote control pairing process.
10. A method for realizing remote control code matching based on a Bluetooth broadcast packet as claimed in claim 9, wherein in step S3, when it is judged that the Bluetooth broadcast packet contains a code matching identifier, it is further judged that the Bluetooth broadcast packet is received. Whether the time of the broadcast packet exceeds the preset time limit for code pairing, if it does not exceed the time limit for code pairing, obtain the remote control ID according to the Bluetooth broadcast packet and record it; if it exceeds the time limit for code pairing, end the current The code matching process; in step S4, when the preset code matching time threshold is not exceeded, when the received number of the Bluetooth broadcast packets containing the code matching identifier of the same remote control ID is greater than or equal to the Bluetooth broadcast of the successful code matching The threshold of the number of packets determines that the remote control is successfully paired.
