The embodiment of the disclosure relates to the technical field of communication, in particular to an ultra-wideband-based equipment control method and an ultra-wideband-based equipment control device.
Background
Currently, iBeacon (byken) by apple company uses BLE (bluetooth low energy) technology, and specifically, uses a broadcast frame named "Advertising frame" in BLE. The advertisement frame is a frame that is periodically transmitted and can be received by any device that supports BLE. Apple does not carefully infer distance in iOS, but only adopts three distance states of close (Immediate), within 1m (Near), and above 1m (Far). When the distance is within 1m, the received signal strength value is reduced substantially in proportion, and when the distance is more than 1m, the received signal strength is not reduced but fluctuates up and down due to the influence of the reflected wave or the like. That is, since the distance cannot be inferred when the distance is more than 1m, it is simply determined as Far, and it is usually placed at a fixed location in a room, thereby performing continuous broadcasting to the surroundings, and is limited by the transmission distance of BLE bluetooth, the coverage area of the bluetooth beacon is limited, and it is necessary for the user to push information by a certain distance near the location of the bluetooth beacon.

It should be noted that the ultra-wideband-based device control method provided by the embodiments of the present disclosure may be configured and executed by a master device and a slave device. Accordingly, the ultra-wideband based device control apparatus may be provided in the master device and the slave device. And is not particularly limited herein.
It should be understood that the number of masters and slaves in fig. 1 is merely illustrative. There may be any number of slave devices, as implementation requires.
With continued reference to fig. 2, a flow 200 of one embodiment of an ultra-wideband based device control method in accordance with the present disclosure is shown. The ultra-wideband-based device control method comprises the following steps:
In this embodiment, an execution subject (e.g., a master device shown in fig. 1) of the ultra-wideband-based device control method may acquire a control instruction through the internet. The internet access method is not limited to wired and wireless. The wireless access mode can be a wifi mode, a cellular mobile communication mode and the like.
The main device can download an instruction packet through a network, after the main device is installed, the local instruction packet is updated, the instruction packet can include types, wherein the types refer to the classification of the instruction packet according to functions, and the instruction packet can be a system instruction, an App instruction and a signal instruction:
1. and the system instruction refers to an instruction for setting system functions of the slave equipment, such as mute, flight mode and the like.
2. The App command refers to operation of App permission in the slave device, such as a pay bank two-dimensional code.
3. And a signal instruction means that the slave equipment operates according to a preset rule, for example, the slave equipment receives an instruction that a user of the intelligent sensor in a bedroom has slept, and controls the robot at home to finish a cleaning task.
The instruction packet may include only one instruction or a plurality of instructions. The data format in the command packet may be: package ID, attribute information, plug-in embodiment. The attribute information includes type, message list, and display format. Plug-in embodiments may be used to indicate an application scenario for a bundle of instructions, e.g., a conference room. The message list may be used to indicate different message contents of the same type. The display format is a format for display at the master device, e.g., a single presentation or multiple presentations.
In the present embodiment, UWB technology may be used for ranging. The master device does not know in advance which slave devices are present and therefore needs to periodically transmit a broadcast signal to detect the slave devices. The slave device returns a response signal after receiving the ranging signal.
And step 203, calculating the distance between the master device and the slave device according to the time difference between the ranging signal and the response signal.
In this embodiment, the time point T of the master device sending the ranging signal is calculated by using the method of two-sided ranging1And the time point T of receiving the response signal2The time difference of (a).
Distance D ═ T between master and slave devices2-T1)/2*C*A。
Where C is the velocity of the wave and a represents a coefficient of the range of movement of the device, may be set. The value of A is larger than 1, and the fluctuation of the range judgment result can be reduced by correcting D through A. For example, when the user moves in a conference room, the user is determined to be in the conference room within a certain range by correcting the distance, and the user is not continuously switched between the indoor and the outdoor.
And step 204, judging whether the slave equipment meets the receiving condition according to the distance.
In this embodiment, if the distance is smaller than the first threshold, it may be determined that the device satisfies the receiving condition. For example, if the master device installed at the cash register detects that the mobile phone (slave device) of the user is less than 10cm away, it may be determined that the slave device satisfies the reception condition.
Alternatively, in order to avoid false detection, the ranging signal may be transmitted multiple times within a predetermined time, the residence time of the slave device within the first threshold range is determined according to the response signal received each time, and if the residence time is greater than the second threshold, the slave device is determined to meet the receiving condition. This prevents accidental events caused by environmental fluctuations or sudden movements of the user from being mistakenly interpreted as the user entering the reception range. A prerequisite for calculating the dwell time is that the master device can distinguish from which slave device the response signal originates. The slave device's response signal therefore needs to include the device identification.
Alternatively, control commands to the slave device may be counted and repeated transmission is not required if a response signal has been previously transmitted and successfully executed by the slave device is received. The slave device does not satisfy the reception condition at this time.
And step 205, if yes, sending a control instruction to the slave device, so that the slave device executes the control instruction.
In this embodiment, the control instruction obtained in step 201 is sent to the slave device by UWB. And after receiving the control instruction, the slave equipment judges whether the master equipment can be trusted, and if so, executes the control instruction. For example, a master device installed at a checkout counter sends a control instruction to a mobile phone near the checkout counter to call a payment two-dimensional code. After the mobile phone receives the control instruction, whether the main equipment is credible or not is checked, and if the main equipment is credible, the payment two-dimensional code is called out, so that manual calling of a user is not needed, and time is saved.
If not, the control instruction is not sent. And continuing to periodically transmit the ranging signal until detecting the slave device meeting the receiving condition to transmit the control command. This reduces the frequency of sending control commands and also reduces interference to the slave devices.
In some optional implementations of this embodiment, the method further includes: in response to detecting that the slave device is directed to a master device, sending an authorization request to the slave device, causing the slave device to whitelist the master device. To protect the user from interference, some settings may be made on the slave device:
1. adding into a white list: when the slave device performs a predetermined operation (e.g., shaking and pointing to the master device), the master device sends an authorization request, and the slave device may set to receive a request for the master device to join the white list. Not only can the UWB technology accurately measure the distance, but also the angle between the slave device and the master device in the signal transmission direction can be measured, and if the angle is smaller than a predetermined value (for example, 5 degrees), the slave device is considered to be directed to the master device.
2. Departure principle: if the command is system level, the settings are restored after leaving the range, e.g., enter the meeting room to mute, and leave to unmute.
In some optional implementations of this embodiment, downloading the instruction packet via the network includes: acquiring scene information of the main equipment; and downloading the instruction packet matched with the scene information through a network. For example, if the master device is applied to a cash register, the downloaded instruction packet is related to payment, and instructions such as mute need not be downloaded.
With further reference to fig. 3, a flow 300 of one embodiment of an ultra-wideband based device control method applied to a slave device is illustrated. The process 300 of the ultra-wideband based device control method comprises the following steps:
In the present embodiment, an execution subject (for example, a slave device shown in fig. 1) of the ultra-wideband-based device control method may receive a ranging signal from a master device through UWB technology. The slave device feeds back a response signal. The response signal may include a device identification for identifying the identity of the slave device. The master device can then know which slave device responded to the ranging signal.
In this embodiment, the slave device needs to perform authentication after receiving the control command. It is first determined whether the master can trust. The control command includes a master device identifier for identifying the identity of the master device. Whether the master device can trust can be set by:
trust mode:
if the master device is set to the trusted mode, instructions from the master device are received and executed each time the master device is approached.
Untrusted mode:
if the master device is an untrusted device, the slave device pops up a message box after receiving an instruction every time the slave device approaches the master device, and prompts a user to operate. For example, after the mobile phone enters a conference room, the mobile phone receives a mute instruction sent by the host device, and a mute option can be popped up on the mobile phone for the user to select. The user may refuse to mute or may agree to mute.
③ blacklist mode:
if the request sent by the main equipment is not wanted to be received any more, the main equipment is added into a blacklist. Control instructions from the blacklist do not pop up a message box to prompt the user, but are discarded directly.
Optionally, the method further comprises: in response to detecting that a user operates the slave device in a predetermined action, transmitting a ranging signal to the master device; in response to receiving an authorization request sent by the master device, adding the master device to a whitelist that can be trusted. For example, when the mobile phone is shaken and then aligned with the master device on the cashier desk, the master device sends an authorization request, and the mobile phone can add the master device to a trusted white list. The control command from the white list pops up a message box to prompt the user to confirm whether to execute the control command.
And step 303, if the trust can be realized, executing a control instruction.
In the present embodiment, the operation is performed in accordance with the control instruction. Optionally, a success message may also be sent to the master device to notify the master device of successful reception of the control instruction. Optionally, if the execution fails, a failure message may be sent to inform the master device to retransmit the control command, or to perform statistics. For example, if the user refuses to mute, the mute is fed back to the master device, and the master device can count which slave devices do not execute the control instruction.
In some optional implementations of this embodiment, in response to detecting that the distance from the master device is not less than the first threshold, resuming the setting before the execution of the system-level control instructions. If the slave device leaves the range set by the master device, the previous operation for entering the range may be cancelled. For example, the mobile phone is muted after the meeting room is in progress, and the muting is canceled after the meeting room is left.
In some optional implementations of this embodiment, the method further includes: recording the received control command; and if the user deletes the target control instruction, the target control instruction is not received any more. The slave device can set whether the locally received instruction continues to be received or not, and if the slave device does not want to receive a certain instruction, the slave device can delete the instruction.
Optionally, the instruction may append an extension. The instruction package may be downloaded from a network. The specific process may be the same as step 201. The slave device may also store the instruction packet and support network download updates.
In some optional implementations of this embodiment, executing the control instruction includes: counting the times of receiving the control instruction; and if the control instruction is received for the first time, executing the control instruction. This avoids repeated execution of the same instruction. For example, after the mute instruction has been received for muting, if the mute instruction is received again, it is ignored.
Fig. 4 is a flowchart of the interaction between a master device and a slave device of an ultra-wideband based device control method according to the present disclosure. The master device first acquires the control command and then sends a ranging signal. And after receiving the ranging signal, the slave device feeds back a response signal to the master device. The master device calculates the distance between the master device and the slave device from the time difference of the two signals. And then judging whether the slave equipment meets the receiving condition according to the distance and the staying time (interference elimination) of the slave equipment. The control instruction may be sent to the slave device if the reception condition is satisfied. The slave device does not directly execute the control instruction after receiving the control instruction, but authenticates the master device and the control instruction, and executes the control instruction after authenticating the master device and the control instruction as a trustable master device and a trustable control instruction. Thereby ensuring the safety of the slave device.
With continuing reference to fig. 5a-5g, fig. 5a-5g are schematic diagrams of an application scenario of the ultra-wideband based device control method according to the present embodiment.
