Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart illustrating a data transmission method according to an embodiment of the present invention, where the data transmission method is applied to a control device in a communication system based on a bluetooth mesh network. As shown in fig. 1, the method comprises the following steps:

step 101: a first controlled device and a second controlled device are determined.

In the embodiment of the invention, the data transmission method can be applied to communication systems such as an intelligent home system and an intelligent office system based on a Bluetooth mesh network, wherein the communication system at least comprises one control device and at least two controlled devices. The control device and the at least two controlled devices have a Bluetooth communication function, and the controlled devices have a Bluetooth communication function, a WIFI communication function and a WIFI direct communication function. The Bluetooth communication is a wireless technical standard, short-distance data exchange between electronic equipment can be realized, and UHF radio waves of ISM wave band of 2.4-2.485 GHz are used; a master may communicate with up to seven slaves in the same piconet. WIFI communication is a technology for connecting an electronic device to a Wireless Local Area Network (WLAN), that is, a technology for converting a wired network signal into a wireless signal, and is a point-to-end connection, and a router is required to allow the device to access during the connection process; typically 2.4G UHF or 5G SHF ISM radio frequency bands are used. Compared with the WIFI communication, the WIFI direct communication is a point-to-point or shared connection mode, and any central control node does not need to be set.

The control device, the first controlled device and the second controlled device are all in the same Bluetooth mesh network, and the control device establishes Bluetooth connection with the first controlled device and the second controlled device respectively. The specific manner in which the control device determines the first controlled device and the second controlled device may be that the control device determines the first controlled device and the second controlled device in a plurality of devices according to a data transmission instruction received by the control device, where the data transmission instruction may include data transmission object information, and the first controlled device and the second controlled device may be determined in the plurality of controlled devices according to the data transmission object information; the control device may also determine the first controlled device and the second controlled device according to a preset transmission rule.

For example, when the control device receives an instruction that the display screen displays a current picture taken by the camera, the camera and the display screen are determined to be the first controlled device and the second controlled device respectively from the plurality of controlled devices. For another example, the user sets 7: the 30 speakers play the sound of the FM106.5 station as an alarm, the control device controls the device to play the sound at 7: and 30 hours, the loudspeaker and the radio are determined to be a first controlled device and a second controlled device respectively.

Step 102: and respectively sending a connection instruction to the first controlled device and the second controlled device through a Bluetooth mesh network so as to establish WIFI connection between the first controlled device and the second controlled device.

After the control device determines the first controlled device and the second controlled device, the control device sends an instruction for establishing WIFI connection with the second controlled device to the first controlled device through the Bluetooth mesh network, and sends an instruction for establishing WIFI connection with the first controlled device to the second controlled device.

After the first controlled device and the second controlled device successfully receive the corresponding connection instructions, WIFI connection signals are respectively transmitted to the opposite side, and therefore WIFI connection between the first controlled device and the second controlled device is established.

For example, after determining that the camera and the display screen are respectively a first controlled device and a second controlled device, the control device sends a connection instruction to the camera and the display screen through the bluetooth mesh network; after the camera and the display screen successfully receive the connection instruction, WIFI connection signals are respectively transmitted to the other side, and therefore WIFI connection is established between the camera and the display screen.

Step 103: and sending a data transmission instruction to the first controlled device and/or the second controlled device through the Bluetooth mesh network so that the first controlled device and the second controlled device perform data transmission through the WIFI connection.

After the first controlled device and the second controlled device establish the WIFI connection, the control device may send a data transmission instruction only to the first controlled device through the bluetooth mesh network, may also send a data transmission instruction only to the second controlled device through the bluetooth mesh network, and may also send a data transmission instruction to the first controlled device and the second controlled device through the bluetooth mesh network, respectively.

Similarly, the control device may detect file information on the first controlled device and/or the second controlled device through the bluetooth mesh network, and control the target transmission file to be transmitted in the WIFI connection by sending a data transmission instruction containing target file information to the first controlled device and/or the second controlled device; the control device may also send a real-time data transmission instruction through the bluetooth mesh network, so that a data file currently generated by the first controlled device or the second controlled device is transmitted in the WIFI connection.

For example, after the camera and the display screen are connected through WIFI, the control device may send a data transmission instruction containing a specific time period to the camera, and the camera receives the data transmission instruction and then transmits a video file shot at the specific time period to the display screen through WIFI connection.

In the embodiment of the present invention, when the communication system is an intelligent home system or an intelligent office system, the control Device may be a Mobile phone, a remote controller, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.

The data transmission method of the embodiment of the invention comprises the steps of determining a first controlled device and a second controlled device; respectively sending a connection instruction to the first controlled device and the second controlled device through a Bluetooth mesh network so as to establish WIFI connection between the first controlled device and the second controlled device; and sending a data transmission instruction to the first controlled device and/or the second controlled device through the Bluetooth mesh network so that the first controlled device and the second controlled device perform data transmission through the WIFI connection. Therefore, when data transmission is needed among the communication system internal devices based on the Bluetooth mesh network, the WIFI connection is established among the internal devices and the data transmission is carried out through the WIFI connection, so that the data transmission efficiency among the communication system internal devices based on the Bluetooth mesh network is improved.

Referring to fig. 2, fig. 2 is a flowchart of a data transmission method according to another embodiment of the present invention, and the main difference between the embodiment and the embodiment shown in fig. 1 is that a WIFI direct connection is established between a first controlled device and a second controlled device. As shown in fig. 2, the method comprises the following steps:

step 201: a first controlled device and a second controlled device are determined.

The implementation process and beneficial effects of this step can be referred to the description in step 101, and are not described herein again.

The first controlled device and the second controlled device both have a WIFI direct connection function, and can establish WIFI direct connection between the first controlled device and the second controlled device and mutually transmit WIFI direct signals.

Optionally, in an embodiment, the step of determining the first controlled device and the second controlled device includes:

the control device selects a first controlled device and a second controlled device, and sends locking instructions to the first controlled device and the second controlled device through a Bluetooth mesh network respectively so as to enable the first controlled device and the second controlled device to enter a locking state. And the first controlled equipment and the second controlled equipment forbid responding to control instructions sent by other equipment except the control equipment in the locking state.

In this embodiment, after the control device selects the first controlled device and the second controlled device from the plurality of devices, the control device further sends a locking instruction to the first controlled device and the second controlled device through the bluetooth mesh network, after receiving the locking instruction, the controlled device in the non-locking state prohibits the response of the control instruction sent by the other devices except the control device, and after receiving the control instruction sent by the other devices, the control device returns the state information that the controlled device is locked to the other devices, so that the other devices will not perform the control instruction on the controlled device in the locking state; after receiving the locking instruction, the controlled device in the locking state does not respond to the locking instruction, and returns the state information that the controlled device is locked.

For example: the control equipment sends a locking instruction to the camera, the first display screen and the second display screen through the Bluetooth mesh network, if the first display screen is in a locking state, and the camera and the second display screen are in a non-locking state, the first display screen does not respond to the locking instruction, and the camera and the second display screen respond to the locking instruction to enter the locking state.

According to the embodiment, after the first controlled device and the second controlled device are selected, the first controlled device and the second controlled device are enabled to enter the locking state, so that interference of other control devices except the control device in the data transmission process can be avoided, and the success rate of data transmission of the subsequent first controlled device and the second controlled device through WIFI direct connection is improved.

It should be noted that this embodiment is an optional embodiment of step 201, and step 201 is not limited to this embodiment for determining the first controlled device and the second controlled device, for example: when the user does not need to enter the locked state for the first controlled device and the second controlled device, the first controlled device and the second controlled device are selected.

The selecting a first controlled device and a second controlled device, and sending a locking instruction to the first controlled device and the second controlled device through a bluetooth mesh network, so as to enable the first controlled device and the second controlled device to enter a locked state, where the first controlled device and the second controlled device prohibit a step of responding to a control instruction sent by a device other than the control device in the locked state, and the method is also applicable to the embodiment shown in fig. 1, and has the same beneficial effects.

Step 202: determining WIFI direct signal transmission power between the first controlled device and the second controlled device.

After a first controlled device and a second controlled device which need to be connected in a WIFI direct connection mode are determined, WIFI direct connection signal transmitting power of the WIFI direct connection is established between the first controlled device and the second controlled device, wherein the WIFI direct connection signal transmitting power between the first controlled device and the second controlled device is related to a spacing distance between the first controlled device and the second controlled device, and the WIFI direct connection signal transmitting power of the WIFI direct connection is established between the first controlled device and the second controlled device through a relation comparison table, a preset formula and other modes after the spacing distance is determined.

The control device can respectively send feedback instructions of position coordinates to the first controlled device and the second controlled device through the Bluetooth mesh network, receive position coordinate information returned by the first controlled device and the second controlled device, and calculate the spacing distance between the first controlled device and the second controlled device according to the two pieces of position coordinate information, so that WIFI direct connection signal transmitting power for establishing WIFI direct connection between the first controlled device and the second controlled device is determined.

Optionally, in an embodiment, the step of determining WIFI direct signal transmission power between the first controlled device and the second controlled device includes:

acquiring a Bluetooth signal intensity value between the first controlled device and the second controlled device, calculating a spacing distance between the first controlled device and the second controlled device according to the Bluetooth signal intensity value, and determining WIFI direct connection signal transmitting power corresponding to the spacing distance; or

And taking the preset maximum transmitting power as the transmitting power of the WIFI signal.

In this embodiment, the manner of obtaining the bluetooth signal strength value between the first controlled device and the second controlled device may be that the control device sends an instruction for detecting the bluetooth signal strength value sent by the first controlled device to the second controlled device when the first controlled device originally sends a bluetooth signal, and receives the bluetooth signal strength value returned after the second controlled device detects the bluetooth signal strength value; or, when the bluetooth signal is not turned on by the first controlled device, after the instruction for turning on the bluetooth signal is sent to the first controlled device, the bluetooth signal strength value between the first controlled device and the second controlled device may be obtained in the previous manner.

The bluetooth signal strength value is related to a separation distance between the first controlled device and the second controlled device, the separation distance between the first controlled device and the second controlled device may be found according to a preset comparison table and the bluetooth signal strength value, or the separation distance between the first controlled device and the second controlled device may be calculated according to the bluetooth signal strength value and a first preset formula, for example: the first predetermined formula is d ═ 10^ ((abs (RSSI) -a)/(10 × n)), where RSSI is the bluetooth signal strength value, a is the bluetooth signal strength when the transmitting end and the receiving end are spaced apart by 1 meter, n is the environmental attenuation factor, and d is the separation distance. After the spacing distance between the first controlled device and the second controlled device is determined, the WIFI direct connection signal transmitting power for establishing the WIFI direct connection between the first controlled device and the second controlled device can be determined by using the preset comparison table and the second preset formula.

In this embodiment, after the distance between the first controlled device and the second controlled device is obtained, the distance may be obtained through a second preset formula: and calculating to obtain WIFI direct connection signal transmitting power for establishing the WIFI direct connection between the first controlled equipment and the second controlled equipment (wherein a and b are preset values, S is the spacing distance, and P is the WIFI direct connection signal transmitting power).

In addition, under any of the conditions that the bluetooth signal intensity value between the first controlled device and the second controlled device is small, the second controlled device does not detect the bluetooth signal intensity of the first controlled device, and the time for determining the WIFI direct connection signal transmission power is saved, the WIFI direct connection signal transmission power can be directly determined to be the preset maximum transmission power. In order to ensure that the WIFI direct connection between the first controlled device and the second controlled device is successful, the preset maximum transmitting power is required to ensure that the two devices at the maximum distance within the specified range can establish the WIFI direct connection.

It should be noted that this embodiment is an alternative embodiment of step 202, and step 202 is not limited to this embodiment for determining the WIFI signal transmission power for establishing the WIFI direct connection between the first controlled device and the second controlled device, for example: after the Bluetooth signal intensity value is obtained, WIFI direct connection signal transmitting power for establishing WIFI direct connection between the first controlled device and the second controlled device can be obtained directly through the Bluetooth signal intensity value according to the characteristic relation between the Bluetooth mesh network and the WIFI direct connection.

Step 203: and sending a connection instruction containing the WIFI direct connection signal transmission power information to the first controlled device and the second controlled device through the Bluetooth mesh network, so that the first controlled device and the second controlled device establish WIFI direct connection with the WIFI direct connection signal transmission power.

After the WIFI direct connection signal transmitting power of the WIFI direct connection is established between the first controlled equipment and the second controlled equipment, a connection instruction containing the WIFI direct connection signal transmitting power information is sent to the first controlled equipment and the second controlled equipment respectively. After receiving the connection instruction, the first controlled device and the second controlled device respectively transmit a WIFI direct connection instruction with power being WIFI direct signal transmission power to each other, so that WIFI direct connection is established between the first controlled device and the second controlled device.

Step 204: and sending a data transmission instruction to the first controlled device and/or the second controlled device through the Bluetooth mesh network so that the first controlled device and the second controlled device can perform data transmission through the WIFI direct connection.

The implementation process and beneficial effects of this step can be referred to the description in step 103, and are not described herein again.

The data transmission method of the embodiment of the invention comprises the steps of determining a first controlled device and a second controlled device; the method comprises the steps of determining WIFI direct connection signal transmitting power between first controlled equipment and second controlled equipment, and enabling the first controlled equipment and the second controlled equipment to establish point-to-point WIFI direct connection through the WIFI signal direct connection transmitting power; and sending a data transmission instruction to the first controlled device and/or the second controlled device through the Bluetooth mesh network so that the first controlled device and the second controlled device can perform data transmission through the WIFI direct connection. Therefore, after the point-to-point WIFI direct connection is established between the first controlled device and the second controlled device, the safety of data transmission between the first controlled device and the second controlled device can be ensured, and meanwhile, the data transmission rate can be increased.

Referring to fig. 3, fig. 3 is a flowchart of a data transmission method according to another embodiment of the present invention, where the data transmission method of the present embodiment is applied to a first controlled device in a communication system based on a bluetooth mesh network. As shown in fig. 3, the method comprises the following steps:

After receiving the control equipment connection instruction in the Bluetooth mesh network, the first controlled equipment determines second controlled equipment according to the connection instruction, and sends a WIFI connection signal to the second controlled equipment, so that WIFI connection is established with the second controlled equipment.

The first controlled device determines the second controlled device in a manner that the connection instruction includes second controlled device information, and the first controlled device determines the second controlled device according to the connection instruction; the first controlled device may also search for the WIFI connection signal sent by the second controlled device according to the connection instruction, so as to determine the second controlled device.

Therefore, when data transmission is needed among the communication system internal devices based on the Bluetooth mesh network, the WIFI connection is established among the internal devices and the data transmission is carried out through the WIFI connection, so that the data transmission efficiency among the communication system internal devices based on the Bluetooth mesh network is improved.

Referring to fig. 4, fig. 4 is a flowchart of a data transmission method according to another embodiment of the present invention, and the main difference between the present embodiment and the embodiment shown in fig. 3 is that a WIFI direct connection is established between a first controlled device and a second controlled device. As shown in fig. 4, the method comprises the following steps:

step 401: and receiving a connection instruction sent by the control equipment through the Bluetooth mesh network.

The implementation process and beneficial effects of this step can be referred to the description in step 301, and are not described herein again.

The first controlled device and the second controlled device both have a WIFI direct connection function and can transmit WIFI direct connection signals for establishing WIFI direct connection between the devices.

Step 402: and determining the transmitting power of the WIFI direct connection signal.

After receiving a connection instruction sent by the control device, the first controlled device determines WIFI direct connection signal transmitting power for establishing WIFI direct connection with the second controlled device. The WIFI direct connection signal transmitting power is related to the spacing distance between the first controlled device and the second controlled device, and the WIFI direct connection signal transmitting power for establishing the WIFI direct connection between the first controlled device and the second controlled device can be determined through a plurality of modes such as a relation comparison table and a preset formula after the spacing distance is determined.

The first controlled device can send a position coordinate acquisition instruction to the second controlled device through the Bluetooth mesh network, receive a position coordinate returned by the second controlled device, determine the position coordinate of the first controlled device, and calculate the spacing distance between the first controlled device and the second controlled device according to the two position coordinates, so that the WIFI direct connection transmitting power for establishing the WIFI direct connection between the first controlled device and the second controlled device is determined.

Optionally, in an embodiment, the step of determining the WIFI direct signal transmission power includes:

The preset maximum transmitting power is used as the transmitting power of the WIFI direct connection signal; or

And receiving transmission indication information which is sent by the control equipment and contains the WIFI direct connection signal transmission power through the Bluetooth mesh network.

In a first case of this embodiment, the first controlled device should obtain a bluetooth signal strength value between the first controlled device and the second controlled device, and a specific obtaining method thereof may be that the first controlled device detects a strength value of a bluetooth signal transmitted by the second controlled device under a condition that the second controlled device originally transmits the bluetooth signal, so as to obtain a bluetooth signal strength value between the first controlled device and the second controlled device; or the first controlled device may send a transmission instruction to the second controlled device through the bluetooth mesh network under the condition that the second controlled device does not transmit the bluetooth signal, the second controlled device transmits the bluetooth signal after receiving the transmission instruction, and then detects the intensity value of the bluetooth signal transmitted by the second controlled device, thereby obtaining the bluetooth signal intensity value between the first controlled device and the second controlled device.

The bluetooth signal strength value is related to a separation distance between the first controlled device and the second controlled device, and after the bluetooth signal strength value between the first controlled device and the second controlled device is obtained, the separation distance between the first controlled device and the second controlled device may be found according to a preset comparison table and the bluetooth signal strength value, or the separation distance between the first controlled device and the second controlled device may be calculated by the bluetooth signal strength value and a first preset formula, for example: the first predetermined formula is d ═ 10^ ((abs (RSSI) -a)/(10 × n)), where RSSI is the bluetooth signal strength value, a is the bluetooth signal strength when the transmitting end and the receiving end are spaced apart by 1 meter, n is the environmental attenuation factor, and d is the separation distance.

Similarly, the WIFI direct connection signal transmitting power for establishing the WIFI direct connection between the first controlled device and the second controlled device is also related to the spacing distance between the first controlled device and the second controlled device, and after the spacing distance is determined, the WIFI direct connection signal transmitting power for establishing the WIFI direct connection between the first controlled device and the second controlled device can be determined by using a preset comparison table and a second preset formula.

In the second case of this embodiment, under any one of the conditions that the bluetooth signal intensity value between the first controlled device and the second controlled device is small, the first controlled device does not detect the bluetooth signal intensity of the second controlled device, and the time for determining the WIFI direct connection signal transmission power is saved, it may be directly determined that the WIFI direct connection signal transmission power is the preset maximum transmission power. In order to ensure that the WIFI direct connection between the first controlled device and the second controlled device is successful, the preset maximum transmitting power is required to ensure that the two devices at the maximum distance within the specified range can establish the WIFI direct connection.

In a third case of this embodiment, the connection instruction received by the first controlled device through the bluetooth mesh network and sent by the control device includes the WIFI direct signal transmission power, and the WIFI direct signal transmission power can be determined according to the connection instruction.

It should be noted that this embodiment is an alternative embodiment of step 402, and step 402 is not limited to this embodiment for determining the WIFI signal transmission power, for example: after the Bluetooth signal intensity value is obtained, WIFI direct connection signal transmitting power can be determined directly through the Bluetooth signal intensity value according to the characteristic relation between the Bluetooth mesh network and the WIFI direct connection.

Step 403: and transmitting a WIFI direct connection instruction to the second controlled equipment according to the WIFI direct connection signal transmitting power so as to establish WIFI direct connection with the second controlled equipment.

After the first controlled device determines the WIFI direct connection signal transmitting power, a WIFI direct connection connecting instruction with the power being the WIFI direct connection signal transmitting power can be transmitted to the second controlled device, meanwhile, the WIFI direct connection connecting instruction sent by the second controlled device is responded, a connection success message returned by the second controlled device is received, and therefore WIFI direct connection is established between the first controlled device and the second controlled device.

Step 404: and receiving a data transmission instruction sent by the control equipment through the Bluetooth mesh network, and performing data transmission with the second controlled equipment through the WIFI direct connection.

The implementation process and beneficial effects of this step can be referred to the description in step 303, and are not described herein again.

Optionally, after step 401, the method further includes:

receiving a locking instruction sent by the control device through the Bluetooth mesh network;

entering a locked state according to the locking instruction, wherein in the locked state, the control instruction sent by other equipment except the control equipment is prohibited from responding;

and if the data transmission is finished, disconnecting the WIFI direct connection and exiting the locking state.

The control device sends a locking instruction to the first controlled device through the Bluetooth mesh network, and the first controlled device receives the locking instruction through the Bluetooth mesh network. When the first controlled device is in the non-locked state, the first controlled device enters the locked state after receiving the locking instruction, the first controlled device is in the locked state, the first controlled device is prohibited from responding to the control instruction sent by other devices except the control device, and the state information that the controlled device is locked is returned to the other devices after receiving the control instruction sent by the other devices, so that the other devices do not carry out the control instruction on the controlled device in the locked state any more. When the first controlled device is in the locked state, the state information that the first controlled device is locked is returned to the control device, so that the control device can not perform control instructions on the controlled device in the locked state any more.

For example: the first controlled equipment is a camera, the camera in the non-locking state receives a locking instruction sent by the control equipment through the Bluetooth mesh network, and the camera enters the locking state to respond to the locking instruction; and the camera in the locked state receives the locking instruction sent by the control equipment through the Bluetooth mesh network, does not respond to the locking instruction and sends the state information that the camera is locked to the control equipment, so that the control equipment does not carry out the control instruction on the camera in the locked state any more.

And after the first controlled equipment entering the locking state finishes data transmission with the second controlled equipment, disconnecting the WIFI direct connection and exiting the locking state. The exit from the locked state may be that the first controlled device automatically exits after detecting that the data transmission is completed, or that the first controlled device sends a data transmission completion message to the control device through the bluetooth mesh network after detecting that the data transmission is completed, and then receives an exit instruction sent by the control device through the bluetooth mesh network, thereby exiting from the locked state.

By locking the first controlled equipment, the interference of other control equipment except the control equipment in the data transmission process can be avoided, and the success rate of data transmission of the subsequent first controlled equipment and the second controlled equipment through WIFI direct connection is improved.

It should be noted that, the locking instruction sent by the control device is received through the bluetooth mesh network; entering a locked state according to the locking instruction, wherein in the locked state, the control instruction sent by other equipment except the control equipment is prohibited from responding; and if the data transmission is finished, disconnecting the WIFI direct connection and exiting the locking state, wherein the steps are optional and do not need to be executed when the controlled equipment does not need to be locked.

In addition, the above steps are also applicable to the embodiment shown in fig. 1, and have the same beneficial effects, specifically: the locking instruction sent by the control equipment is received through the Bluetooth mesh network; entering a locked state according to the locking instruction, wherein in the locked state, the control instruction sent by other equipment except the control equipment is prohibited from responding; if the data transmission is finished, the WIFI connection is disconnected, and the locked state is exited, that is, the step of disconnecting the WIFI direct connection when the data transmission is applied to the embodiment shown in fig. 4 is to disconnect the WIFI connection when the data transmission is applied to the embodiment shown in fig. 3.

According to the data transmission method, the connection instruction sent by the control equipment is received through the Bluetooth mesh network; determining WIFI direct connection signal transmitting power; transmitting a WIFI direct connection instruction to the second controlled equipment according to the WIFI direct signal transmission power so as to establish point-to-point WIFI direct connection with the second controlled equipment; and receiving a data transmission instruction sent by the control equipment through the Bluetooth mesh network, and performing data transmission with the second controlled equipment through the WIFI connection. Therefore, after the point-to-point WIFI direct connection is established between the first controlled device and the second controlled device, the safety of data transmission between the first controlled device and the second controlled device can be ensured, and meanwhile, the data transmission rate can be increased.

Referring to fig. 5, fig. 5 is a flowchart of a data transmission method according to another embodiment of the invention. As shown in fig. 5, includes:

step 501: the control device determines a first controlled device and a second controlled device.

The control device may be factory default of the communication system or user-defined. After the control device is determined, the first controlled device and the second controlled device which perform WIFI direct connection data transmission are determined by the control device.

In the process that the control device determines the first controlled device and the second controlled device from the plurality of controlled devices, the control device may first detect the states of the controlled devices, if the controlled devices in the locked state are detected, the control device abandons the controlled devices, and continues to detect the state of the next controlled device until two controlled devices meeting the data transmission condition are determined; the states of all the controlled devices meeting the data transmission condition may be detected together, and the first controlled device and the second controlled device may be determined from the non-locked state.

Step 502: the control device sends connection instructions to a first controlled device and a second controlled device through a Bluetooth mesh network, and the first controlled device and the second controlled device respectively transmit Bluetooth signals after receiving the connection instructions.

Step 503: whether the first controlled device and the second controlled device can search for or connect with each other for the bluetooth signal transmitted by the other.

If so, go to step 504: the first controlled device and the second controlled device calculate the spacing distance between the first controlled device and the second controlled device according to the strength value of the searched or connected Bluetooth signal, and calculate the WIFI direct signal transmitting power according to the spacing distance.

The strength value of the bluetooth signal is related to the separation distance between the first controlled device and the second controlled device, and the separation distance between the first controlled device and the second controlled device can be determined in various ways such as a relational comparison table and a preset formula. Similarly, the WIFI direct connection signal transmitting power is also related to the spacing distance, and the WIFI direct connection signal transmitting power can be determined in a plurality of modes such as a relation comparison table and a preset formula.

If not, go to step 505: and determining the transmitting power of the WIFI direct connection signal to be the preset maximum power.

Step 506: according to the WIFI signal transmitting power, the first controlled equipment and the second controlled equipment establish WIFI direct connection, and the first controlled equipment sends a connection success message to the control equipment through the Bluetooth mesh network after the WIFI direct connection is successful;

the first controlled equipment and the second controlled equipment both transmit WIFI direct connection instructions with power being WIFI direct signal transmission power, and therefore WIFI direct connection between the first controlled equipment and the second controlled equipment is established.

Step 507: after the control device sends a data transmission instruction to the first controlled device and/or the second controlled device through the Bluetooth mesh network, the first controlled device and the second controlled device perform data transmission through the WIFI direct connection according to the data transmission instruction.

In the data transmission method of the embodiment of the invention, the first controlled equipment and the second controlled equipment are determined by the control equipment; the control equipment respectively sends connection instructions to first controlled equipment and second controlled equipment through a Bluetooth mesh network, and the first controlled equipment and the second controlled equipment respectively transmit Bluetooth signals after receiving the connection instructions; judging whether the first controlled equipment and the second controlled equipment can search or connect the Bluetooth signals transmitted by the other side or not; if yes, the first controlled device and the second controlled device calculate the spacing distance between the first controlled device and the second controlled device according to the strength value of the searched or connected Bluetooth signal, and calculate the WIFI direct connection signal transmitting power according to the spacing distance; if the WIFI direct connection signal cannot be transmitted, determining that the transmitting power of the WIFI direct connection signal is the preset maximum power; according to the WIFI direct connection signal transmitting power, the first controlled equipment and the second controlled equipment establish WIFI direct connection, and the first controlled equipment sends a connection success message to the control equipment through the Bluetooth mesh network after the WIFI direct connection is successful; after the control device sends a data transmission instruction to the first controlled device and/or the second controlled device through the Bluetooth mesh network, the first controlled device and the second controlled device perform data transmission through the WIFI direct connection according to the data transmission instruction. Therefore, after the point-to-point WIFI direct connection is established between the first controlled device and the second controlled device, the safety of data transmission between the first controlled device and the second controlled device can be ensured, and meanwhile, the data transmission rate can be increased.
