In the embodiment of the present disclosure, the data frame may be composed of a Header (Header), a Payload (also referred to as a data portion, etc.), a trailer (Footer), and so on. The Frame header may be composed of a Frame Control field (Frame Control), a Frame Sequence Number (Sequence Number), an address field (Addressing Fields), and the like.

In this embodiment of the present disclosure, the second type data frame is at least formed by an address field of the second type data frame and a load portion of the second type data frame, for example: for example: the device type of the controlled device is a single-channel receiver, the first type is basic state query, the content of the first command is empty, and the like, and the load part is sequentially written in. After determining the address field and the load part of the second-class data frame, the electronic device inserts other parts such as a frame head or a frame tail according to a preset rule to generate a complete second-class data frame.

In some embodiments, the byte length corresponding to the payload portion of the second type of data frame is determined by the type of the command.
In the embodiment of the present disclosure, the byte length corresponding to the payload part of the second type data frame may be variable, and the byte length may be determined by the type of the command. For example: the command is a command for data processing, and the payload portion of the second type data frame may have a byte length of 5 bytes, the device control command may have a byte length of 7 bytes, the device management command may have a byte length of 9 bytes, and so on. The present disclosure can save transmission resources, and quickly determine the type of a command, etc. by the payload part of the second type data frame of different byte lengths.
In some embodiments, when the command is of a first type, the payload portion of the second type of data frame is determined by a device type of the controlled device, the first type, and a first command content;
the first command content is determined by the type of the command.
In this disclosure, the first type may refer to a device control command, and after the data frame is acquired, it may be determined whether an address field of the data frame is a source identifier or a target identifier to obtain a determination result, and then determine a corresponding data frame type according to the determination result. After the data Type of the data carried by the preset bits in the frame control field of the data frame is determined to be the first Type (i.e., the device control command) carried by the command in the data frame, the first command content (Cmd Date) corresponding to the command of the first Type can be determined according to the Type (Cmd Type) of the command. If the electronic device determines that the type of command is a device control command, the content of the corresponding command may be determined only depending on the type of command, for example: the basic status query corresponds to a command content being null, and the basic Switch controls the corresponding command content to be a first Byte representing Channel information, a second Byte representing switching information, and the like (for example, but not limited to, Byte 1: Channel, Byte 2: Switch). The electronic Device may then determine a Payload portion (Frame Payload) of the second Type of data Frame according to the Device Type (Device Type), the first Type (Cmd Type, 1 Byte) and the first command content (Cmd Date) of the controlled Device. According to the method and the device, the first command content is determined by the type of the command, so that the corresponding command content and the like can be accurately determined.

In this embodiment of the disclosure, when the command is of a first type and the control parameter of the control device is null, the load part of the second type data frame may only need to be determined by the device type of the controlled device and the first type, for example: if the device type of the controlled device is the curtain motor and the first type is the basic status query, the load part of the second type data frame can be jointly determined based on the device type being the curtain motor and the first type being the basic status query. By adopting the above mode, the transmission resource can be saved, the transmission efficiency can be improved, and the like.
In some embodiments, when the command is of a second type and the command of the second type has the first attribute, the payload portion of the second-class data frame is determined by a device type of the controlled device, the second type, and a second command content;
the second command content is determined by the type of the command.
The properties of a command may refer to the indispensable properties that the command has, such as: encrypted attributes and unencrypted attributes, public attributes and private attributes, common attributes and uncommon attributes, and the like.

The first attribute may refer to a public attribute, which may be understood as a limited enumeration of general management commands (e.g., without limitation, switch states, etc.) capable of being applied to the controlled device. When the electronic device determines that the device management command is a public attribute, the second command content (Cmd Date) may be determined only by the Type of command (Cmd Type), for example: when the command type is a device management command and has a public attribute, the second command content may be that the indicator light is turned on or off, and the like.
The electronic Device may then determine a Payload part (Frame Payload) of the second Type Data Frame, etc., according to the Device Type (Device Type), the second Type (Management Cmd Type), and the second command content (Cmd Data) of the controlled Device. For example: the controlled equipment is a 3-way wall switch with a gesture sensing function, a second type of the controlled equipment is a gesture sensing function and an indicator light which are configured with the wall switch, a second command content of the controlled equipment is indicator light starting, and the like, and the controlled equipment is sequentially written into a load part. After determining the address field and the load part of the second-class data frame, the electronic device inserts other parts such as a frame head or a frame tail according to a preset rule to generate a complete second-class data frame.
In this embodiment of the disclosure, when the command is of a second type and the command of the second type has a first attribute, a second command content corresponding to the command of the second type may be determined, a load portion of the data frame of the second type may be determined according to the device type of the controlled device, the second type, and the second command content, and the data frame of the second type may be generated according to an address field of the data frame of the second type and the load portion of the data frame of the second type. By adopting the above mode, the data structure of different types of data frames can be accurately set, various information such as transmission direction and command type can be determined, transmission efficiency can be improved, and running power consumption can be saved.

In this embodiment of the present disclosure, the second type may refer to a device management command, and may include: and configuring a gesture sensing function and an indicator light of the wall switch, or reading the gesture sensing function and the indicator light configuration of the wall switch. The second attribute may refer to a private attribute, which may be understood as a command specific to a certain type of controlled device (e.g., without limitation, detecting facial expressions, etc.). When the electronic Device determines that the Device management command is a private attribute, the third command content (Cmd Date) needs to be determined by the Device Type (Device Type) of the controlled Device and the Type (Cmd Type) of the command, for example: when the command type is a device management command and has a private attribute, the second command content corresponding to the device type a may be an induction distance, and the third command content corresponding to the device type B may be gesture induction control.
The electronic Device may then determine a Payload part (Frame Payload) of the second Type Data Frame, etc. according to the Device Type (Device Type), the second Type (Management Cmd Type), and the third command content (Cmd Data) of the controlled Device. For example: the device type of the controlled device is a light adjustable device with a gesture sensing function, the second type is a gesture sensing function detected by reading the light adjustable device, the third command content is indicating lamp opening and the like, and the light adjustable device with the gesture sensing function, the gesture sensing function detected by reading the light adjustable device and the indicating lamp opening can be sequentially written into the load part. After determining the address field and the load part of the second-class data frame, the electronic device inserts other parts such as a frame head or a frame tail according to a preset rule to generate a complete second-class data frame.
In this embodiment of the disclosure, when the command is of a second type and the command of the second type has a second attribute, determining a third command content corresponding to the command of the second type according to the device type of the controlled device, determining a load portion of the data frame of the second type according to the device type of the controlled device, the second type, and the third command content, and generating the data frame of the second type according to an address field of the data frame of the second type and the load portion of the data frame of the second type. By adopting the above mode, the data structure of different types of data frames can be accurately set, various information such as transmission direction and command type can be determined, transmission efficiency can be improved, and running power consumption can be saved.
In some embodiments, the method further comprises:
determining a third type data frame according to the second type data frame; the data types of data carried by preset bits in frame control fields of the third type data frame, the first type data frame and the second type data frame are different; the third type data frame comprises: an address field and a payload part, the address field of the third type data frame being determined by the source identification; the load part of the third type data frame is determined by the device type of the controlled device, the type of the command and the content of a fourth command;

The address field of the third type data frame is determined by the source identification and can be used for determining the corresponding control device, and the load part of the third type data frame is determined by the device type of the controlled device, the type of the command and the content of the fourth command. The third type data frames corresponding to the second type data frames with different generation modes may also be different, for example: when the type of the command is a device control command, the corresponding type of the command can be a first type of third-class data frame; when the type of the command is a device management command, the corresponding type of the command can be a second type of third data frame; when the device management command has the public attribute, the third type data frame of the second type also has the corresponding public attribute, and when the device management command has the private attribute, the third type data frame of the second type also has the corresponding private attribute.
For a third type of data frame of the first type, the fourth command content may be determined only by the device type of the controlled device; for a third type of data frame of a second type having a common attribute, the fourth command content may be determined only by the type of the command; for the third type data frame of the second type having the private attribute, the fourth command content needs to be determined by the type of the command and the device type of the controlled device together.
By adopting the above mode, the data transmission states of the control equipment and the controlled equipment can be accurately and timely determined, and the running power consumption of the electronic equipment is saved.
In some embodiments, the frame control field of the second type data frame carries forwarding information;
the forwarding information is used for triggering the function of the controlled device for forwarding data to other controlled devices.
In the embodiment of the present disclosure, the forwarding information may include information such as the number of times of forwarding, a forwarding time interval, and the like. The controlled device may have a function of forwarding data so as to increase a transmission distance of a data frame. For example: the electronic device sends the second type of data frame to the controlled device a at the first location, then the controlled device a may send the second type of data frame to the controlled device B at the second location, then the controlled device B may send the second type of data frame to the controlled device C at the third location, and so on. In the process of forwarding data, the controlled devices such as A, B and C may perform both corresponding command contents and forwarding, or may perform only forwarding without performing the corresponding command contents. A. The controlled devices such as B and C may also perform processing such as filtering or inserting new information on the second type data frame, and then perform forwarding, and the like, and the disclosure is not limited in particular.
In the process of forwarding, if the forwarding is performed for an unlimited number of times, the forwarding cannot be stopped or the occupied frequency band is too large, which adversely affects the transmission performance of the wireless transmission system, so that a certain forwarding stop rule can be set. The electronic device may set a FRAME Header (FRAME Header) mode for writing the forwarding times into the data FRAME, and stop forwarding when a certain forwarding time (for example, greater than 2 times) is reached. For example: and when the controlled equipment receives the forwarded second-class data frame and the number of read forwarding times is 3, stopping forwarding to other controlled equipment, and terminating the forwarding process and the like by the controlled equipment. The controlled device a may update the current forwarding number (RC) in the second type data frame received from the intelligent control center from 0 to 1, and then the controlled device B may update the current forwarding number in the second type data frame received from the controlled device a from 1 to 2, until the preset forwarding number is reached 3, and so on.

For example: the length of the data frame is 5 bytes, and the electronic device can insert the check information a (check code a) and the check information B (check code B) after the 1 st byte and the 5 th byte, respectively. The electronic device can perform first verification on the number 1byte according to the verification information A to obtain a verification result a. The electronic device may perform the second verification on the byte number 2-5 according to the verification information B to obtain a verification result B, or the electronic device may perform the second verification on the byte number 1, the byte number 2-5 and the verification result a together according to the verification information B to obtain the verification result B, and the like.

in step 202, receiving a matching result from the intelligent control center; wherein the matching result is used for establishing communication connection between the control device and the controlled device.
Here, the controlled device (also referred to as a receiver) may be a device capable of receiving and executing commands and having a wireless transmission function, and for example, may refer to a device for receiving and executing commands such as control and management and having a wireless transmission function such as radio frequency wireless transmission and reception, infrared transmission and reception, bluetooth transmission and reception, and WiFi transmission and reception. In some embodiments, the controlled device may include: wall switch, single-way executor, multi-way executor, electric curtain, lamp, TV set, air conditioner and other equipment.
In the embodiment of the present disclosure, the intelligent control center may include: a terminal device, a gateway device, a cloud server, or the like, for example, a mobile terminal or a fixed terminal. Wherein, the mobile terminal can include: the mobile phone, the tablet computer, the notebook computer or the wearable device may further include a smart home device, for example, a smart sound box. The fixed terminal may include: desktop computers or smart televisions, etc. The intelligent control center may be a relay device or the like for performing matching, filtering, or clipping or other processing on the command during the wireless transmission of the control device and the controlled device. The control device may first send the command to the intelligent control center, and then the intelligent control center forwards the processed command to the controlled device matched with the control device, and the like. Of course, data frame transmission between the controlled device and the control device is also possible.

For example: the intelligent control center may refer to one module or unit in the control device, or the intelligent control center may refer to one module or unit in the controlled device, that is, the control device or the controlled device may include functions of the intelligent control center, and the like.
The controlled device may send the state information of the controlled device to an intelligent control center, so that the intelligent control center matches the control device with the controlled device according to the state information of the controlled device and the state information of the control device. The state information of the controlled device may include address identification of the controlled device, motion, brightness, loudness and other state information of the controlled device, and the state information of the control device may include address identification of the control device, opening and closing degree of the control device, detected control parameters and other state information. For example: the intelligent control center matches the control equipment with a certain address identification with the controlled equipment with a certain address identification according to the thought or automatic setting according to a certain rule, and sends the address identification information of the control equipment to the controlled equipment, so that the controlled equipment can directly control the controlled equipment subsequently after storing the address identification information of the control equipment, and once the matching relation is established through the address identification, all control information of the control equipment can be applied to the controlled equipment. For example, if a control switch is pressed on and off, once the switch is matched with the controlled device, the controlled device is opened above the switch and the controlled device is closed below the switch. The intelligent control center determines that the state information of the controlled equipment A is that the loudness is gradually decreased from high to low, the state information of the controlled equipment B is that the brightness is changed from on to off, the state information of the control equipment a is changed from on to off, and the state information of the control equipment B is that the pressing grade is gradually increased.

As shown in fig. 4A, a transmission diagram of wireless data transmission may be represented.

The transmitting device 401 may be a self-generating switch, a battery switch, a sensor, etc., and the receiving device 402 may be a wall switch, a single-way actuator, a multi-way actuator, a motorized window shade, a light, etc. The receiving device 402 is of various types, and the receiving device 402 and the smart control center 403 can communicate with each other bidirectionally, acquire data from each other, and transmit control commands and the like. The transmitting device 401, the receiving device 402 and the intelligent control center 403 can all communicate with each other, and the information flow of the whole system has various choices. For example: the transmitting device 401 to the receiving device 402, the receiving device 402 to the intelligent control center 403 may be selected, the transmitting device 401 to the intelligent control center 403, the intelligent control center 403 to the receiving device 402, and the like may be selected.

The data length of the command content of the message transmitted by the transmitting device or the intelligent control center or the receiving device can be changed, and different data lengths can be obtained according to different message command types. For example: for a transmitting device, the DATA may be 1Byte in length. The data transmitted by the transmitting device needs a certain triggering condition, and the triggering condition can be that the transmitting device is powered on, can also transmit at fixed time, or the data of the sensor in the transmitting device changes. The transmitting device may load the DATA content based on the signals collected by the sensor, and not load the sensor DATA if the sensor DATA is empty. Then reloads TYPE data defining the TYPE of the emitting device, for example: the transmitting means may be defined as a switch and may also be defined as a type of switch. For example: the switch of the transmitting device is defined to be of a turnover type, and after the switch is pressed each time and the receiving device receives a turnover type message, turnover operation is executed once. It can also be defined that the type of the switch of the transmitting device is fixed, and the receiving device will perform the fixed on or off operation after receiving the message each time.
