The current house industry intellectuality becomes a trend, and various electronic sofas, the intelligent control of electronic deck chair product gradually become people's rigidity demand in daily, by the house equipment with bluetooth communication control widely used.
At present, the intelligent control based on bluetooth communication still needs the manual connection of user to pair controlgear for operation flow is loaded down with trivial details, leads to user experience poor, and, when the sofa is more, perhaps when personnel are more the user hardly distinguishes the sofa that every bluetooth corresponds control specifically be which interference problem. Based on this, the method and the device for controlling the smart home device provided by the embodiment of the invention can alleviate the technical problem.
In order to facilitate understanding of the embodiment, a detailed description is first given to a method for controlling smart home devices disclosed in the embodiment of the present invention.
The first embodiment is as follows:
an embodiment of the present invention provides a method for controlling an intelligent home device, where the method is applied to a controller of an intelligent home device, and as shown in fig. 1, the method includes the following steps:
step S102, acquiring broadcast data packets periodically transmitted by a plurality of control terminals;
step S104, extracting a signal value in each broadcast data packet;
during specific implementation, in order to realize the communication connection between the controller of the smart home device and the control terminal, in this embodiment, bluetooth connectionless broadcast communication is adopted as a basic communication link, where the control terminal may be an intelligent terminal such as a smart phone or a tablet computer that can be networked.
Specifically, the control terminal can periodically send a broadcast data packet to a controller of the smart home device within a set range according to a preset sending period, where the broadcast data packet is a communication data packet specified in a bluetooth low energy protocol, the controller can extract a signal value in each received broadcast data packet, and meanwhile, the controller can also extract a bluetooth identification address in each broadcast data packet, and the bluetooth identification address is used as a basis for identifying the identity of the control terminal, so that the controller can clearly know which control terminals send the specifically received broadcast data packets.
S106, screening out a control terminal closest to the intelligent household equipment according to the signal value;
step S108, judging whether the nearest control terminal is in a locking state;
and step S110, if not, controlling the intelligent household equipment according to the broadcast data packet sent by the nearest control terminal.
When the intelligent home equipment is actually used, the controller determines which control terminal is closest to the controller according to the signal value in the broadcast data packet sent by each control terminal, and when the controller judges that the control terminal closest to the controller currently does not control other intelligent home equipment, namely the closest control terminal is in a non-locking state, the intelligent home equipment is controlled according to the broadcast data packet sent by the closest control terminal.
According to the intelligent home equipment control method provided by the embodiment of the invention, when the broadcast data packets sent by a plurality of control terminals regularly are obtained, the signal value in each broadcast data packet is extracted, the control terminal closest to the intelligent home equipment is screened out through the signal value, whether the closest control terminal is in a locking state or not is judged, and if not, the intelligent home equipment is controlled according to the broadcast data packet sent by the closest control terminal; the problem of control interference of multiple intelligent terminals to multiple control devices and the problem of complex operation process caused by manual connection pairing of the control devices are effectively solved.
Specifically, in order to clarify how the controller selects the control terminal closest to the smart home device according to the signal value in the plurality of control terminals, step S106 may be implemented by step 11 and step 12 based on this:
step 11, calculating a distance value between each control terminal and the intelligent household equipment according to the signal value;
and step 12, screening out the minimum distance value from the plurality of distance values, and determining the control terminal corresponding to the minimum distance value as the nearest control terminal.
In practical applications, the signal value is usually referred to as a signal strength value, i.e., a distance value can be calculated from the signal strength value. Specifically, the distance value between each control terminal and the smart home device is calculated according to the signal value and the expression of the distance value, then the minimum distance value is screened out from the calculated distance values, and the control terminal corresponding to the minimum distance value is determined as the nearest control terminal. Wherein the expression of the distance value is:
in the distance value expression, rssi represents a signal value, n represents an environment attenuation factor, and a represents a signal value when the control terminal is one meter away from the intelligent household equipment；
During specific use, after the controller determines the nearest control terminal, in order to avoid that multiple controllers repeatedly lock the same control terminal, it is further necessary to further determine whether the control terminal closest to the controller is in a locked state, and based on this, step S108 may be implemented by step 21, step 22, step 23, and step 24:
step 21, receiving synchronous data packets sent by other controllers;
step 22, extracting the identification information of the locked control terminal carried in the synchronous data packet;
step 23, judging whether the identification information is consistent with the identity carried in the broadcast data packet sent by the nearest control terminal;
and 24, if not, determining that the nearest control terminal is in a non-locking state.
Generally, the current controller receives and extracts a synchronization data packet which is sent by another controller and carries identification information of a locked control terminal, if the identification information is an identity of the control terminal, the current controller judges whether the identification information is consistent with an identity carried in a broadcast data packet sent by a determined nearest control terminal, if not, the current controller indicates that the nearest control terminal determined by the current controller is not locked by another controller, the nearest control terminal is in a non-locked state, and if so, the current controller indicates that the nearest control terminal determined by the current controller is locked by another controller, that is, the nearest control terminal is in a locked state.
Further, when the controller determines that the nearest control terminal is in a non-locked state, the control terminal can control the smart home device, and specifically, the step of controlling the smart home device according to the broadcast data packet sent by the nearest control terminal includes: establishing a locking relation with the nearest control terminal; extracting a control code in a broadcast data packet sent by a nearest control terminal; and controlling the intelligent household equipment by using the control code.
In actual use, only when the current controller determines that the nearest control terminal is in a non-locking state, the control terminal can establish a locking relation with the current controller, the current controller extracts a control code in a broadcast data packet sent by the nearest control terminal, and the intelligent home equipment is controlled by using the control code.
Specifically, if the current controller determines that the nearest control terminal is in the locked state, the current controller enters a preemption flow, that is, the current controller and the controller locking the control terminal preempt the control terminal according to a signal value in a broadcast data packet sent by the control terminal, wherein the current controller is in a preemption state, and the controller locking the control terminal is in a locked state. Fig. 2 shows a preemption flow chart, as shown in fig. 2, comprising the steps of:
step 202, the current controller extracts the signal value in the broadcast data packet sent by the control terminal to be locked;
step 204, the current controller receives and extracts the signal value in the synchronous data packet sent by the controller locking the control terminal;
step 206, judging whether the signal value in the extracted broadcast data packet is greater than the signal value in the extracted synchronous data packet; if yes, go to step S208; if not, executing step S210;
step 208, the current controller successfully locks the control terminal;
in step 210, the control terminal fails to control locking of the control terminal.
Further, after establishing a locking relationship with the nearest control terminal, the method further comprises: and sending the synchronous data packet to other controllers.
In practical application, after the controller and the control terminal establish a locking relationship, a synchronous data packet is sent to other controllers, and the synchronous data packet is mainly used for informing other controllers in a Bluetooth signal range of the control terminal currently locked by the other controllers and preventing the other controllers from repeatedly locking the control terminal.
Specifically, the controller in the locked state continuously receives broadcast data packets sent by other control terminals, and the controller in the locked state determines whether there is another control terminal closer to itself according to a signal value in the broadcast data packet, and usually determines whether to release a current locking relationship with the locked control terminal through the following processes (1) to (4), where the specific processes are as follows:
(1) acquiring broadcast data packets periodically transmitted by a plurality of control terminals;
(2) extracting a signal value in each of the broadcast packets;
(3) judging whether the signal intensity corresponding to the signal value of the nearest control terminal is higher than the signal intensities corresponding to the signal values of other control terminals or not according to the signal values;
(4) and if not, releasing the locking relation established with the nearest control terminal.
In specific implementation, when a plurality of control terminals are provided, the controller in the locked state needs to judge whether the locked relation is released with the locked control terminal according to the signal strength corresponding to the signal value in the broadcast data packet sent by the plurality of control terminals in real time, so as to ensure that the control terminal closest to the controller can control the smart home device.
Further, when there are multiple controllers, the controller in the locked state may also continuously receive the synchronization packets sent by other controllers, and when it is found that there are other controllers in the synchronization packets trying to lock the controller that has been locked by itself, the current controller enters a preempted flow, where a specific preempted process is as follows: the current controller can extract the signal value of the synchronous data packet and judge whether the signal value of the synchronous data packet is larger than the signal value of the broadcast data packet which is extracted by the current controller and sent by the locking control terminal, if so, the current controller and the locking control terminal are unlocked; if not, the current controller and the locked control terminal are unlocked.
According to the above embodiment, the states of the controller in the control process of the smart home device may be divided into an idle state, a preemption state, and a locking state, fig. 3 shows a state transition diagram of the controller, and as shown in fig. 3, when the controller is in the idle state 300, the synchronous data packet is not sent, and only the synchronous data packet is received. And continuously receiving the broadcast data packet sent by the control terminal, selecting the control terminal closest to the signal value according to the signal value, and starting to try to connect, thereby entering a preemption state.
When the controller is in the preemption state 301, the control terminal closest to the controller enters the locked state if it is not locked by other controllers. And if the control terminal closest to the controller is locked by other controllers, starting to preempt the flow, if the preemption is successful, entering a locking state, and if the preemption is unsuccessful, entering an idle state.
When the controller is in the locked state 302, a synchronization packet is sent while a synchronization packet is received. And starting to receive the control code sent by the locked control terminal, controlling the intelligent household equipment to move according to the control code, and entering an idle state if the locked control terminal is locked by other controllers and preempted.
In a specific implementation, the controller is usually a Central Processing Unit (CPU) of the entire smart home device, and may be configured with a corresponding operating system and a control interface, and may be a Digital logic controller that can be used for automatic control, such as a single chip, a DSP (Digital Signal Processing), an ARM (Advanced RISC machine, ARM processor), and the like, and may load a control instruction into a memory at any time for storage and execution, and meanwhile, units such as a CPU instruction and a data memory, an input/output Unit, a power module, and a Digital analog Unit may be built in, and may be specifically set according to an actual use situation.
In order to implement the above-mentioned smart home device control method, fig. 4 shows a schematic circuit structure, as shown in fig. 4, a controller 400 of each smart home includes a single chip 401, and a bluetooth module 402 and a synchronization module 403 connected to the single chip, and for convenience of description, only two control terminals 404 are shown in fig. 4. When in specific use, the Bluetooth module of the current controller can receive the broadcast data packets sent by the two control terminals, the Bluetooth module sends the two broadcast data packets to the single chip microcomputer, the single chip microcomputer screens out the control terminal closest to the current controller according to the signal value extracted from each broadcast data packet, and judges whether the nearest control terminal establishes a locking relationship with other controllers according to the synchronous data packet received by the synchronous module and sent by the other controllers through the synchronous module, if the nearest control terminal does not establish a locking relationship with other controllers, the current controller singlechip controls a driving circuit 405 of the smart home connected with the singlechip by a control code extracted from a broadcast data packet sent by the nearest control terminal, therefore, automatic control over the smart home is achieved, and the current controller can send information of the control terminal locked by the current controller to other controllers through the synchronization module.
