[0045] like Figure 1 As shown, an embodiment of the present application provides a device pairing method, including steps 101 to 103.

[0046] Step 101: The master device sends a broadcast frame on a pairing channel. The broadcast frame includes information about the master device.

[0047] In an exemplary embodiment, the pairing system includes a master device and a slave device, and the master device and the slave device can communicate on a wireless communication channel.

[0048] The wireless communication channels in the embodiments of the present disclosure include, but are not limited to, 3G technology for cellular networks, Zigbee for Wireless Personal Area Network Communication Technologies (WPAN), Bluetooth or Ultra Wide Band (UWB) technology, IEEE 802.11 Wireless Local Area Network (WLAN), and Radio Frequency Identification (RFID) for wireless identification technology (e.g., Near Field Communication (NFC)).

[0049] In one exemplary embodiment, the host device may be a head mounted display.

[0050] In an exemplary embodiment, the slave device may be an interactive device such as a handle, a glove, a mouse, or a keyboard.

[0051] In this embodiment, the pairing channel refers to the communication channel used by the master device and the slave device when pairing. The pairing channel can be one or more pre-configured universal fixed frequencies. Taking the IEEE 802.11 wireless local area network (WLAN) as an example, the pairing channel can be configured as one or more fixed frequencies in the 2.4 GHz frequency band.

[0052] In an exemplary embodiment, the broadcast frame also includes information of one or more second slave devices that have been paired with the master device.

[0053] When the master device's memory stores information about a paired second slave device, the master device places the stored information about the second slave device in a broadcast frame and sends it, so that any slave device does not need to record any pairing information. Each time it is turned on, it receives the master device's broadcast frame on the pairing channel and obtains the current paired information from the broadcast frame.

[0054] In an exemplary embodiment, the information of the second slave device includes information such as an identification number (ID) of the second slave device and a device type of the second slave device.

[0055] In an exemplary embodiment, the master device may send a broadcast frame on the pairing channel at a predetermined period. The predetermined period is a set period, which may be set according to the possible response time of the slave device, such as 5 seconds, 10 seconds, etc.

[0056] Step 102: The master device receives a first pairing request from a first slave device, where the first pairing request includes information about the first slave device, information about the master device, and received signal strength indication information.

[0057] In this embodiment, the first slave device refers to a slave device that is not recorded in the paired devices of the master device before the master-slave device is connected. The second slave device refers to a slave device that is recorded in the paired devices of the master device before the master-slave device is connected.

[0058] Received Signal Strength Indication (RSSI) is an optional part of the wireless transmission layer and is used to determine the link quality. The RSSI value corresponds to the unit of decibel milliwatt (dBm), which represents the relative relationship between a certain power and 1mw. The specific calculation formula of the value x (dBm) and the power P (mw) is as follows:

[0059]

[0060] It can be seen that RSSI is not power, it is just an indication of signal strength.

[0061] In an exemplary embodiment, the received signal strength indication information included in the first pairing request may be RSSI information in a broadcast frame received by the first slave device from the master device. At this time, after the first slave device receives the broadcast frame sent by the master device on the pairing channel, the RSSI information in the broadcast frame is placed in the first pairing request and sent to the master device. The master device determines the distance between the two according to the RSSI information, and then decides whether to pair with the first slave device. At this time, the processing logic on the first slave device side can be simplified;

[0062] In another exemplary embodiment, the received signal strength indication information included in the first pairing request may also be the RSSI information of the first pairing request received by the master device from the first slave device. At this time, the first slave device determines the distance between the two based on the RSSI information in the broadcast frame, which is independent of the master device's determination of the distance between the two based on the RSSI information in the first pairing request, and does not affect each other, thereby avoiding the situation where the first slave device deceives the master device by generating RSSI information.

[0063] Step 103: The master device sends a pairing response to the first slave device according to the received signal strength indication information.

[0064] In an exemplary embodiment, step 103 specifically includes:

[0065] The master device detects the distance between the first slave device and the master device according to the received signal strength indication information, and sends a pairing response to the first slave device according to the distance between the first slave device and the master device.

[0066] In an exemplary embodiment, the master device estimates the distance d between the first slave device and the master device according to the wireless channel transmission model and the received RSSI value as:

[0067] ;d=10^((abs(RSSI)-A) / (10*n)) (1);

[0068] Where: d-calculated distance (m);

[0069] RSSI-received signal strength (negative value);

[0070] A-Signal strength when the transmitter and receiver are 1 meter apart (in dBm);

[0071] n-environmental attenuation factor.

[0072] In an exemplary embodiment, when the distance d between the first slave device and the master device is less than or equal to a preset distance threshold, the master device sends a pairing response to the first slave device;

[0073] When the distance d between the first slave device and the master device is greater than a preset distance threshold, the master device does not send a pairing response to the first slave device.

[0074] In another exemplary embodiment, when the distance d between the first slave device and the master device is less than or equal to a preset distance threshold, the master device sends a pairing success response to the first slave device;

[0075] When the distance d between the first slave device and the master device is greater than a preset distance threshold, the master device sends a pairing failure response to the first slave device.

[0076] In this embodiment, the preset distance threshold may be between 0 cm and 20 cm. The preset distance threshold is defined as the distance when the master device and the first slave device are very close to each other, so that when the user brings the master device and the slave device close enough, pairing can be achieved, thereby achieving the effect of "one touch to connect".

[0077] In another exemplary embodiment, step 103 specifically includes:

[0078] The master device detects whether the received signal strength indication in the first pairing request is greater than or equal to a preset received signal strength indication threshold;

[0079] If the received signal strength indication in the first pairing request is greater than or equal to a preset received signal strength indication threshold, sending a pairing response to the first slave device;

[0080] If the received signal strength indication in the first pairing request is less than a preset received signal strength indication threshold, no pairing response is sent to the first slave device.

[0081] In the embodiment of the present disclosure, according to the above formula (1) and the preset distance threshold of 0 to 20 cm, the value range of the preset received signal strength indication threshold can be reversely derived. The value range is also related to the values ​​of A and n in formula (1). Under different devices and different environmental conditions, the preset received signal strength indication threshold value is also different.

[0082] In yet another exemplary embodiment, step 103 specifically includes:

[0083] The master device detects whether the received signal strength indication in the first pairing request is greater than or equal to a preset received signal strength indication threshold;

[0084] If the received signal strength indication in the first pairing request is greater than or equal to a preset received signal strength indication threshold, sending a pairing success response to the first slave device;

[0085] If the received signal strength indication in the first pairing request is less than a preset received signal strength indication threshold, a pairing failure response is sent to the first slave device.

[0086] In an exemplary embodiment, when the broadcast frame further includes information of one or more second slave devices that have been paired with the master device, the method further includes:

[0087] The master device receives a second pairing request from a second slave device, where the second pairing request includes information about the second slave device and information about the master device;

[0088] The master device sends a pairing response to the second slave device.

[0089] In this embodiment, when the broadcast frame also includes information of one or more second slave devices that have been paired with the master device, after receiving the broadcast frame, the second slave device can directly send a second pairing request to the master device (because the master device no longer needs to pair with the second slave device based on the received signal strength indication information, the second pairing request may not include the received signal strength indication information at this time). After the master device sends the pairing response, the master device and the second slave device can be quickly and automatically paired.

[0090] In an exemplary embodiment, the method further comprises:

[0091] The master device records the first slave device as a paired device.

[0092] Since in the embodiment of the present disclosure, the first slave device refers to a slave device that has not been recorded in the paired devices of the master device before the master-slave device is connected this time, and the second slave device refers to a slave device that has been recorded in the paired devices of the master device before the master-slave device is connected this time, therefore, when the master device records the first slave device as a paired device, the first slave device will be transformed into the second slave device when it is connected next time, that is, it is no longer necessary to detect the received signal strength indication information in the broadcast frame, but can be paired directly with the master device based on the paired device information in the broadcast frame.

[0093] In an exemplary embodiment, the master device records the first slave device as a paired device, including:

[0094] When the number of currently paired devices is less than the preset maximum number of paired devices, the master device directly records the first slave device as a paired device;

[0095] When the number of currently paired devices is equal to the preset maximum pairing number, the master device erases one or more currently paired devices and records the first slave device as a paired device.

[0096] In an exemplary embodiment, the maximum number of paired devices recorded by the master device may be 2.

[0097] At this time, when the master device does not record any paired device information, or when the master device includes a paired device and the information of the paired device is different from that of the newly paired first slave device, the master device can directly add the newly paired first slave device to the paired devices; when the master device includes two paired devices and the information of the two paired devices is different from that of the newly paired first slave device and one or both of them have not established a connection with the master device, the master device can erase the information of one or two paired devices and then record the newly paired first slave device as a paired device.

[0098] In an exemplary embodiment, the method further comprises:

[0099] The master device detects the number of currently connected slave devices;

[0100] When the number of currently connected slave devices reaches the preset connection number threshold, stop sending broadcast frames.

[0101] In an exemplary embodiment, the preset connection quantity threshold may be 2. That is, when the number of currently connected slave devices reaches 2, the master device stops sending broadcast frames and completely switches to the communication channel.

[0102] In an exemplary embodiment, when the number of currently connected slave devices is greater than 0 and less than a preset connection number threshold (for example, when the number of currently connected slave devices is 1), the master device performs data communication with the connected slave devices on the communication channel, and continues to send broadcast frames on the pairing channel during the time gap of data interaction, waiting for pairing requests from other slave devices. When the number of currently connected slave devices reaches the preset connection number threshold, the master device no longer sends broadcast frames on the pairing channel.

[0103] In an exemplary embodiment, the communication channel may be a wireless channel with the best channel quality detected by the master device.

[0104] The 802.11 working group divides wireless network signals into two independent frequency bands, namely 2.4GHz and 5.0GHz. Each frequency band is divided into several channels, and each country formulates its own policies on how to use these frequency bands. For example, in China, the 2.4GHz frequency band is divided into 13 channels (because the distance between channels 1, 6 and 11 is far enough, they have become the three most commonly used channels that do not overlap and interfere with each other), and the 5.0GHz frequency band is divided into 4 channels.

[0105] Since the 802.11b / g WLAN standard uses the most commonly used 2.4GHz radio frequency band, in actual work and life, wireless routers will not only be interfered by WiFi co-frequency signals emitted by other wireless routers in the wireless signal coverage area, but also by non-WiFi signals emitted by devices such as microwave ovens, Bluetooth mobile phones or laptops in the same working frequency band. In an exemplary embodiment, the wireless router determines the channel quality of each wireless channel in the following manner:

[0106] On all wireless channels of the current working frequency band, the strength of the WiFi co-channel interference signal is detected. In an exemplary embodiment, on a wireless channel, detecting the strength of the WiFi co-channel interference signal includes: sending a probe request frame on the current channel, staying on the channel for a period of time, waiting to receive the probe response frame from other wireless routers, and when the probe response frame from other wireless routers is received, extracting the signal strength information from the received probe response frame, taking the sum of the signal strengths of all received probe response frames as the strength of the WiFi co-channel interference signal on the channel, and switching to the next wireless channel.

[0107] Detect the strength of non-WiFi interference signals of all wireless channels. In an exemplary embodiment, detecting the strength of non-WiFi interference signals of all wireless channels includes: starting a spectrum scanning mode, periodically scanning non-WiFi interference signals received by the wireless router in the entire working frequency band; extracting the strength of the non-WiFi interference signal corresponding to each channel from the received non-WiFi interference signals.

[0108] The strength of the non-WiFi interference signal on each channel is added to the strength of the WiFi co-channel interference signal to obtain the co-channel interference signal strength on each channel.

[0109] The channel with the smallest co-channel interference signal strength is regarded as the wireless channel with the best channel quality.

[0110] In an exemplary embodiment, the pairing response includes information of the master device and information of the slave device, and also includes any one or more of the following information: communication channel, communication address, and time synchronization information.

[0111] In an exemplary embodiment, the method further includes: the master device performing data communication with the first slave device on a communication channel.

[0112] In this embodiment, after the master device selects the wireless channel with the best channel quality as the currently used communication channel, it sends a pairing response containing the communication channel information to the slave device. After receiving the pairing response, the slave device switches to the communication channel. After that, the data transmission between the master and slave devices will be in the channel with the least wireless pressure at present, without interference from other devices and without other devices grabbing data transmission resources.

[0113] The device pairing method provided in this embodiment enables the master device to decide whether to establish pairing with the slave device according to the received signal strength indication information, thereby achieving rapid and automatic pairing between the master device and the slave device and improving the user experience.

[0114] like Figure 2 As shown, the embodiment of the present application also provides a device pairing method, including steps 201 to 203.

[0115] Step 201: The slave device receives a broadcast frame from the master device on a pairing channel. The broadcast frame includes information about the master device and received signal strength indication information.

[0116] In an exemplary embodiment, the broadcast frame further includes information of one or more second slave devices paired with the master device.

[0117] In an exemplary embodiment, the information of the second slave device includes information such as an identification number (ID) of the second slave device and a device type of the second slave device.

[0118] Step 202: The slave device sends a pairing request to the master device according to the received signal strength indication information.

[0119] In an exemplary embodiment, step 202 specifically includes:

[0120] The slave device detects the distance between the slave device and the master device according to the received signal strength indication information, and sends a pairing request to the master device according to the distance between the slave device and the master device.

[0121] In an exemplary embodiment, the slave device estimates the distance d between the slave device and the master device according to the wireless channel transmission model and the received RSSI value as:

[0122] ;d=10^((abs(RSSI)-A) / (10*n)) (1);

[0123] Where: d-calculated distance (m);

[0124] RSSI-received signal strength (negative value);

[0125] A-Signal strength when the transmitter and receiver are 1 meter apart (in dBm);

[0126] n-environmental attenuation factor.

[0127] When the distance d between the slave device and the master device is less than or equal to a preset distance threshold, the slave device sends a pairing request to the master device;

[0128] When the distance d between the slave device and the master device is greater than a preset distance threshold, the slave device does not send a pairing request to the master device.

[0129] In this embodiment, the preset distance threshold may be between 0 cm and 20 cm. The preset distance threshold is defined as the distance when the master device and the first slave device are very close to each other, so that when the user brings the master device and the slave device close enough, pairing can be achieved, thereby achieving the effect of "one touch to connect".

[0130] In another exemplary embodiment, step 202 specifically includes:

[0131] The slave device detects whether a received signal strength indication in the broadcast frame is greater than or equal to a preset received signal strength indication threshold;

[0132] If the received signal strength indication in the broadcast frame is greater than or equal to a preset received signal strength indication threshold, sending a pairing request to the master device;

[0133] If the received signal strength indication in the broadcast frame is less than a preset received signal strength indication threshold, no pairing request is sent to the master device.

[0134] Step 203: The slave device receives a pairing response from the master device.

[0135] In an exemplary embodiment, when the broadcast frame further includes information of one or more second slave devices paired with the master device, the method further includes:

[0136] The slave device detects whether its own information is the same as the information of the second slave device included in the broadcast frame;

[0137] When the own information is the same as the information of the second slave device included in the broadcast frame, the slave device sends a second pairing request, where the second pairing request includes the information of the slave device and the information of the master device;

[0138] The slave device receives the pairing response sent by the master device.

[0139] In this embodiment, when the broadcast frame also includes information of one or more second slave devices that have been paired with the master device, after receiving the broadcast frame, the second slave device can directly send a second pairing request to the master device (because the master device no longer needs to pair with the second slave device based on the received signal strength indication information, at this time, the second pairing request does not include the received signal strength indication information). After the master device sends the pairing response, the master device and the second slave device can be quickly and automatically paired.

[0140] When the own information is different from the information of the second slave device included in the broadcast frame or the broadcast frame does not include the information of the second slave device, the slave device can decide whether to send the first pairing request according to the received signal strength indication information in the broadcast frame. Here, the first pairing request includes the received signal strength indication information. The master device determines the distance between the master device and the slave device according to the received signal strength indication information in the first pairing request, and then decides whether to pair with the slave device. The specific process is referred to the aforementioned step 202, which will not be repeated here.

[0141] In an exemplary embodiment, the pairing response includes information of the master device and information of the slave device, and also includes any one or more of the following information: communication channel, communication address, and time synchronization information.

[0142] In an exemplary embodiment, the method further includes: the slave device performing data communication with the master device on a communication channel.

[0143] The device pairing method provided in this embodiment enables the slave device to decide whether to establish pairing with the master device according to the received signal strength indication information, thereby achieving rapid and automatic pairing between the master device and the slave device, thereby improving the user experience.

[0144] The present application embodiment also provides a slave device, such as Figure 3 As shown, the slave device 3 includes: a first memory 31 and a first processor 32. The first memory 31 stores a computer program. When the computer program in the first memory 31 is executed by the first processor 32, the device pairing method described in any of the above embodiments with the slave device as the execution subject is executed.

[0145] The present application also provides a main device, such as Figure 4 As shown, the main device 4 includes: a second memory 41 and a second processor 42. The second memory 41 stores a computer program. When the computer program in the second memory 41 is executed by the second processor 42, the device pairing method described in any of the above embodiments with the main device as the execution subject is executed.

[0146] The present application also provides a device pairing system. Figure 5 As shown, the device pairing system 5 includes: at least one slave device 51 as described in the above embodiment, and a master device 52 as described in the above embodiment.

[0147] An embodiment of the present application further provides a computer-readable storage medium, on which computer-executable commands are stored, and the computer-executable commands are used to execute the device pairing method provided in any of the above embodiments with the slave device as the execution subject.

[0148] An embodiment of the present application further provides a storage medium on which computer executable commands are stored.
