Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a flowchart of a terminal bluetooth switch control method according to an embodiment of the present application, and as shown in fig. 1, the terminal bluetooth switch control method is applicable to a terminal bluetooth switch, and specifically includes:
s11: the terminal Bluetooth switch initializes the internal protocol to the HID protocol;
an HID (Human Interface Device) protocol is, for example, the bluetooth HID mouse protocol.
S12: sending broadcast information to a Bluetooth control end through an HID protocol;
s13: after receiving a connection Signal fed back by a Bluetooth control end, sending a connection parameter change command to the Bluetooth control end during the establishment of each Bluetooth connection event so as to refresh the Received Signal Strength Indication (RSSI) between the Bluetooth control end and the terminal Bluetooth switch in real time;
the connection parameter is at least one of a connection interval, a timeout time and a device delay, and the parameter of reducing the connection interval, reducing the timeout time, especially reducing the slave device delay to the minimum, for example setting the device delay to 0, is modified to realize real-time updating of RSSI.
Bluetooth low energy connection events are connections in which a master device sends a packet to a slave device at each connection event. A connection event refers to a process of transmitting a packet between a master device and a slave device to each other. The connection event is always performed at a frequency, and each data packet waits for 150 μ s to be transmitted after the last data packet is transmitted. The connection interval determines the interaction interval between the master device and the slave device; it refers to the time distance at which two consecutive connection events begin, and can be anywhere from 7.5ms to 4s, but must be an integer multiple of 1.25 ms. To determine the actual interaction interval of the slave device with the master device, a slave device latency parameter is needed, representing how many connection events the slave device can ignore before it must listen. Each connection event may continue from the time the master sends a packet until either the master or the slave stops responding. No data packets are sent between the master and slave devices outside of the connection event.
Therefore, when the terminal Bluetooth is controlled by the traditional method, the RSSI can be refreshed untimely due to reasons such as low-power Bluetooth sleeping and the like, so that the on-off control is untimely, and the user experience is influenced.

Wherein, terminal bluetooth switch includes but not limited to electric motor car alarm, garage parking stall lock, hotel lock, intelligent lock, the hotel gets electric switch, burglar alarm etc..
The traditional control method for the terminal state change-over switch based on the Bluetooth mainly comprises two methods: one is that bluetooth low energy (bluetooth low energy) establishes a connection with an intelligent terminal. The low-power-consumption Bluetooth sends a broadcast, a Bluetooth program in the mobile phone is opened, the low-power-consumption Bluetooth equipment can be viewed, after the connection with the low-power-consumption Bluetooth equipment is established, the automatic switching function can be completed only by sending Received Signal Strength Indication (RSSI) to the low-power-consumption Bluetooth in real time, but due to the requirement of the endurance of the mobile phone, the non-system program process in the mobile phone can be closed in an indefinite time, and therefore when the Bluetooth program is closed, the mobile phone approaches the low-power-consumption Bluetooth equipment again, and the terminal state can not be automatically switched. The other mode is that dual-mode Bluetooth is utilized, namely, classic Bluetooth and low-power Bluetooth coexist, and because the classic Bluetooth headset mode does not need the participation of a Bluetooth APP program in a mobile phone, Bluetooth connection is not closed. However, classic bluetooth only transmits audio streams, and low-power-consumption bluetooth is used for receiving and sending control and setting commands, so that a dual-mode bluetooth chip can only work in one state at the same time, and therefore two modes of classic bluetooth and low-power-consumption bluetooth need to be frequently switched, inconvenience is brought to users.
In this embodiment, the method for controlling the bluetooth switch of the terminal comprises initializing an internal protocol to an HID protocol by the bluetooth switch of the terminal, sending broadcast information to the bluetooth control end through the HID protocol, sending a connection parameter change command to the bluetooth control end during each bluetooth connection event establishment period after receiving a connection signal fed back by the bluetooth control end to refresh the RSSI between the bluetooth control end and the bluetooth switch of the terminal in real time, comparing the RSSI between the bluetooth control end and the bluetooth switch of the terminal with a preset threshold value to automatically switch the switch state according to the comparison result, and since the HID protocol is used, the process corresponding to the HID protocol belongs to the system process, the bluetooth connection process is not ended, thereby continuously controlling the bluetooth switch of the terminal, changing the connection parameters during each bluetooth connection event establishment period, and refreshing the RSSI between the bluetooth switch of the terminal and the bluetooth control end in real time, timely control is realized, and user experience is improved.
An embodiment of the present invention provides another terminal bluetooth switch control method, as shown in a flowchart in fig. 2, where the terminal bluetooth switch control method includes:
s201: initializing the internal protocol of the terminal Bluetooth switch into a Bluetooth HID mouse protocol;
the HID mouse protocol of the Bluetooth with low power consumption, namely the protocol in the Universal Serial Bus-Human Interface Device Bluetooth Human-computer Interface Device, reflects that the protocol is a Bluetooth mouse at a mobile phone end, because the mouse and the like are the most common external input devices of terminal equipment, a driving program is transferred into a mobile phone system, and the protocol has high priority, and can be connected and transmit data without additional APP processing. The problem of ordinary low-power consumption bluetooth need APP and the automatic hand of bimodulus bluetooth be switched etc. not enough is solved, just connect the switch to open when can reaching the cell-phone and being close the low-power consumption bluetooth, the switch is closed when leaving, can carry out manual control on the cell-phone simultaneously.
S202: the terminal Bluetooth switch starts to send broadcast information and waits for the connection or pairing of the Bluetooth control ends;
s203: if the pairing signal is the pairing signal, judging whether the pairing is successful, if so, executing S204, otherwise, executing S205;
s204: after the pairing is successful, the information is saved, and S207 is continuously executed;
s205: judging whether the pairing frequency exceeds a threshold value within a preset time range;
s206: if yes, alarm information is sent, and the terminal Bluetooth switch and the Bluetooth control end are not paired any more within a preset time range.
In order to enhance the security, besides the password pairing and the encrypted data transmission by using the bluetooth protocol, the present embodiment sets the upper limit of the password pairing time within the specified time to alarm or cancel the pairing, thereby avoiding trying to perform the password pairing for many times, and greatly enhancing the use security.
S207: if the signal is a connection signal, updating the RSSI of the Bluetooth control end and the terminal Bluetooth switch at intervals of preset time in real time;
s208: judging whether the RSSI is greater than the approximate value;
s209: if yes, controlling a terminal Bluetooth switch to be turned on;
s210: judging whether the RSSI is less than a leaving value;
s211: if yes, the terminal Bluetooth switch is controlled to be closed.
The terminal Bluetooth switch is a low-power Bluetooth switch, and the RSSI millisecond-level real-time refreshing of the low-power Bluetooth switch is realized after the low-power Bluetooth switch is connected with the mobile phone. Because of the bluetooth low energy design of low power consumption, two bluetooth low energy equipment establish the connection back, and all communication events are gone on through the connection incident to most of time all is in the sleep state, can lead to the bluetooth low energy to read the RSSI of bluetooth control end to terminal bluetooth switch in real time, even set up after the connection and reduce the connection interval and also can not read the RSSI of bluetooth control end to terminal bluetooth switch in real time. The connection event is that the Bluetooth control end initiates connection, and RSSI real-time refreshing cannot be solved even if the low-power Bluetooth switch does not stop sending data. The invention utilizes the low-power consumption Bluetooth switch to send a command for changing the connection parameters to the Bluetooth control end (mobile phone) during the establishment of each connection event, modifies and reduces the connection interval, reduces the overtime time, particularly reduces the parameter of the slave equipment delay to the minimum, such as to 0, and ensures that each terminal Bluetooth switch needs to reply, thereby refreshing the RSSI in real time.
In some embodiments, the bluetooth control end sets the control valid threshold and/or the control invalid threshold in advance according to a use scenario.
The Bluetooth control end is also provided with a manual switch for controlling the terminal Bluetooth switch, and the manual switch is used for controlling the state switching of the terminal Bluetooth switch.
When a plurality of Bluetooth control terminals exist, the method further comprises the following steps:
the terminal bluetooth switch includes proximity switch, when there are a plurality of bluetooth control ends, still includes:
after the proximity switch receives the proximity signal, the terminal Bluetooth switch checks whether an external Bluetooth controller is connected with the equipment;
if not, when the terminal Bluetooth switch is provided with an alarm device, the alarm device is controlled to send an alarm signal;
if yes, after receiving the RSSI fed back by the Bluetooth control end, judging whether the RSSI fed back by the Bluetooth control end is larger than an approach value set by a terminal Bluetooth switch or not;
if yes, controlling a terminal Bluetooth switch to be turned on;
if the RSSI fed back by the Bluetooth control end is not greater than the set approach value of the terminal Bluetooth switch, rescanning and waiting whether other external Bluetooth control ends are connected; if no other external Bluetooth control ends are connected, alarming;
if other external Bluetooth control ends are connected and the received RSSI is greater than the set approach value of the terminal Bluetooth switch, controlling the terminal Bluetooth switch to be turned on;
otherwise, an alarm signal is sent out.
It should be noted that, when there are multiple bluetooth control terminals, only one bluetooth control terminal can be connected to the terminal bluetooth switch at the same time.
According to the working principle of Bluetooth, when the low-power-consumption Bluetooth is connected with one of the two mobile phones, the other mobile phone can not be connected at the same time, and unless the current connected mobile phone is manually disconnected or automatically disconnected after leaving the use distance range, the experience of manually disconnecting the Bluetooth on the mobile phone is poor. In this embodiment, a proximity switch is set in the bluetooth low energy, the proximity switch may be a touch switch, a light-sensitive switch, a vibration switch, or other light-sensitive switches, and when the mobile phone contacts the proximity switch of the bluetooth low energy, the bluetooth low energy will detect whether the mobile phone is an effective mobile phone, that is, whether the RSSI is within the proximity value, if so, the bluetooth low energy is turned on, and if not, the bluetooth low energy starts to re-scan. After rescanning, because the mobile phone which is not connected last time needs subsequent internal operation, the mobile phone which is not connected originally is directly connected to the low-power-consumption Bluetooth, and the time difference is utilized to ensure that the contacted mobile phone which is not connected originally is connected immediately after the low-power-consumption Bluetooth is rescanned, and the mobile phone which is connected originally can be disconnected and cannot compete for the opportunity of reconnection. This mode is suitable for the working environment where the bluetooth low energy proximity switch is in contact with the cell phone or the user. Therefore, the noninductive switching between the two Bluetooth connection devices is realized.
Therefore, the change of the distance between the mobile phone and the low-power-consumption Bluetooth is sensed through the RSSI in real time, the user experience is excellent, the switch can be started within 0.1 second when the distance is close to the preset value, and the switch can be disconnected after the distance is 0.1 second when the distance is away from the preset value. For example, the RSSI setting is-60 BD, and the distance between the mobile phone and the Bluetooth low energy is about 8 meters. The switch state can be accurately switched by calculating the walking speed of the human body and the distance of plus or minus 0.5 meter (namely 7.5-8.5 meters) under the same use condition. In the prior art, because connection parameters are not changed when connection is established every time, the refreshing of the RSSI is not real-time, the RSSI is delayed for at least 3-20 seconds, and even the RSSI broadcasted before the connection can only be refreshed, so that the approach and the leaving distance of a user are not exact, and the error is extremely large. Such as waiting 3-10 seconds or even longer as close as possible or moving away until the signal is broken.
In some embodiments, a method for noninductive unlocking of an electric vehicle based on bluetooth pairing comprises the following steps:
1. the HID mouse protocol is initiated. After the initialization is successful, the Bluetooth is put into a Bluetooth HID mouse protocol, a broadcast data packet is prepared, and the interval broadcast is started. And the like are discovered and connected by the intelligent terminal.
2. And (6) pairing. To connect the mobile phone with the bluetooth low energy switch, the pairing is performed first. In order to prevent illegal connection, the invention uses password pairing, and the pairing can be successfully carried out to enter the connection only if the password is correct. In order to avoid the decryption of multiple password pairing, the upper limit of the password pairing times in the specified time is alarmed and the pairing is cancelled, so that the user can use the password pairing device safely.
3. And (5) real-time RSSI comparison. And after the intelligent terminal is functionally connected with the low-power-consumption Bluetooth switch, opening a Bluetooth connection message window and acquiring the signal strength RSSI at an interval of 0.1 second for measuring and calculating the distance between the Bluetooth switch and the mobile phone. RSSI setting value approach and exit values, DB number approach greater than exit value, as in fig. 3, open switch scenario: when the mobile phone is close to the Bluetooth low energy switch, the mobile phone is in a disconnected state farthest away, the Bluetooth low energy switch is automatically connected after the mobile phone is close to a connection range, the mobile phone can give an alarm if an alarm function is added before the mobile phone is close to a leaving value (including disconnection), and the mobile phone is in a silent state between the leaving value and the approaching value and is not alarmed or switched. The switch is automatically opened after the mobile phone reaches the approach value. Switching off the switching scene: when the alarm is not given, the switch is closed, and the alarm is turned on. If the Bluetooth is detected to be disconnected, the switch is directly closed and an alarm state is started. In an application scenario without an alarm function, only one threshold may be set.
4. And (6) data communication. Data transmission and receiving with the bluetooth low energy switch can be accomplished to cell-phone APP after connecting for the automatic control of controlling part switch and settlement parameter, but do not participate in the switch.
5. The two control ends are used in a non-inductive switching mode. When two mobile phones are detected to be bound with one low-power-consumption Bluetooth switch device through pairing, the low-power-consumption Bluetooth switch starts a non-inductive switching process. As described above, if the light-sensitive switch of the bluetooth low energy device is turned on, it indicates that someone comes to the nearest place of the bluetooth low energy switch, and thus the RSSI is within the proximity value and is legally close, and the switch is turned on according to the normal flow. If the connection of the mobile phone is not detected at the moment, the low-power-consumption Bluetooth switch is illegally accessed, and the alarm is started when the alarm is given. If the RSSI is not within the approximate value, the effective hand is connected with the low-power-consumption Bluetooth switch, but whether the effective hand is the other hand is uncertain, so that the rescanning is started immediately, and if the second mobile phone is within the approximate value, the effective hand is connected with the low-power-consumption Bluetooth switch in a preemptive manner while the originally connected mobile phone has an interval of disconnection operation, and the switch is opened in a normal process. If the second mobile phone is not connected or the RSSI of the original mobile phone is not within the close value, the switch is disconnected and an alarm is given according to the normal flow when the RSSI of the original mobile phone is not within the leaving value.
It should be noted that this application only uses the noninductive lock of electric motor car to add the unblock usage scenario to exemplify, and this application usage scenario includes but not limited to electric motor car alarm, garage parking stall lock, hotel's lock, intelligent lock, hotel get electric switch, burglar alarm etc..
The invention belongs to the field of utilizing a Bluetooth mouse protocol, and can be automatically realized without using a mobile phone APP. The RSSI can be refreshed in real time, the Bluetooth connection can be established quickly in time, and meanwhile, the noninductive switching of two mobile phones connected with the unified low-power Bluetooth device can be realized.
The terminal Bluetooth switch control method provided by the embodiment can refresh RSSI in real time and switch a system level Bluetooth induction technology based on a Bluetooth HID mouse protocol in an inductionless manner, low-power-consumption Bluetooth switch equipment in an HID Bluetooth mouse mode is connected with automatic Bluetooth of a matched mobile phone, automatic on-off of wireless induction of the mobile phone and the switch equipment can be realized, a user only needs to carry the mobile phone and does not need APP in a screen-off state of the mobile phone, the switch can be automatically realized by approaching a set distance according to the RSSI signal intensity, the user does not need to carry a key with him, and the method is very convenient.
