The frame control domain contains basic frame information with the length of 16 bits, the frame sequence number is used for distinguishing the data frames which are transmitted successively, and the address domain is used for determining the transmission direction of the data frames and the like; the length of the load part is variable, and the specific content is determined by the frame type; the end of frame may be a 16bit cyclic redundancy check (Cyclic Redundancy Check, CRC) value of the frame header and payload data, etc.

In the embodiment of the disclosure, the address field of the first type of data frame may be determined by the source identifier, and the address field of the second type of data frame may be determined by the destination identifier. For example: the electronic device determines that the data frame is of a first type, then it may be determined that the address field in the data frame is written with the source identifier 192.168.102.7 or a number of a specific number of bits, and that the data frame is of a second type, then it may be determined that the address field in the data frame is written with the destination identifier 192.168.202.7 or a number of a specific number of bits, and so on. The electronic device can simply and quickly determine the type or the transmission direction of the data frame through the address field, and the like, thereby being beneficial to improving the transmission efficiency. The payload portion of the first type of data frame may be formed jointly by the device type of the control device and the control parameters, for example: the control device determines that the device type of the control device is a circular double-key switch (corresponding number D2 can be marked), and the control parameter is 01 (i.e. the a key is open, the b key is closed, and the like), and then the control device can write the device type D2 and the control parameter 01 into a load part in a data frame, and the like.

In the embodiment of the disclosure, the source identifier can be used for determining the address field of the first type data frame, the target identifier can be used for determining the address field of the second type data frame, and the equipment type and the control parameter of the control equipment jointly form the load part of the first type data frame, so that the data structures of different types of data frames can be accurately set, the data frame types are refined, the workload of developers is reduced, and the like.

After determining the address field and the load part of the second class data frame, the electronic device inserts other parts such as the frame head or the frame tail according to a preset rule to generate a complete second class data frame. By adopting the mode, the data structure of different types of data frames can be accurately set, various information such as the transmission direction, the type of the command and the like can be definitely transmitted, the transmission efficiency is improved, and the running power consumption and the like are saved.

In the embodiment of the disclosure, the byte length corresponding to the payload portion of the second type of 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 then the byte length corresponding to the payload portion of the second type data frame may be 5 bytes, the byte length corresponding to the device control command may be 7 bytes, the byte length corresponding to the device management command may be 9 bytes, and so on. The method and the device can save transmission resources and quickly determine the type of the command and the like through the load parts of the second class data frames with different byte lengths.

the first command content is determined by the type of the command.

In the embodiment of the present disclosure, the first type may refer to a device control command, after a data frame is acquired, it may be determined whether an address field of the data frame is a source identifier or a target identifier, a determination result is obtained, and then a corresponding data frame type is determined according to the determination result. After determining that the command carried in the data frame is of a first Type (i.e. a device control command) by presetting the data Type of the data carried by the bit in the frame control field of the data frame, the first command content (Cmd Date) corresponding to the command of the first Type may then be determined according to the Type (Cmd Type) of the command. The electronic device determines that the type of command is a device control command, then the corresponding command content may be determined depending only on the type of command, for example: the basic state query corresponds to a command content being null, the basic switch control corresponds to a command content being a first Byte representing channel information, a second Byte representing switching information, etc. (e.g., without limitation, byte 1:Channel,Byte 2:Switch), etc. The electronic device may then determine a Payload portion (Frame Payload) of the second Type of data Frame based on the device Type (DEVICE TYPE) of the controlled device, the first Type (Cmd Type,1 Byte), and the first command content (Cmd Date). The method and the device can accurately determine the corresponding command content and the like by setting the first command content to be determined by the type of the command.

In the embodiment of the disclosure, when the command is of a first type and the control parameter of the control device is null, the load portion 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: the device type of the controlled device is a curtain motor, the first type is a basic state query, and the load part of the second type data frame can be determined jointly based on the device type being the curtain motor and the first type being the basic state query. By adopting the mode, transmission resources can be saved, transmission efficiency can be improved, and the like.

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 (Cmd Type) of the command, for example: when the command type is a device management command and has public attribute, the second command content can be the on or off of the indicator light.

The electronic device may then determine a Payload portion (Frame Payload) of the second type of Data Frame, etc., based on the device type (DEVICE TYPE) of the controlled device, the second type (MANAGEMENT CMD TYPE), and the second command content (Cmd Data). For example: the device type of the controlled device is a 3-way wall switch with a gesture sensing function, the second type is a gesture sensing function for configuring the wall switch, an indicator lamp is arranged, the second command content is that the indicator lamp is turned on, and the like, and the load part is sequentially written. After determining the address field and the load part of the second class data frame, the electronic device inserts other parts such as the frame head or the frame tail according to a preset rule to generate a complete second class data frame.

In an embodiment of the present disclosure, the second type may refer to a device management command, and may include: the gesture sensing function and the indicator lamp of the wall switch are configured, or the gesture sensing function and the indicator lamp configuration of the wall switch are read. The second attribute may refer to a private attribute that 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 together, 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 can be a sensing distance, and the third command content corresponding to the device type B can be gesture sensing control and the like.

The electronic device may then determine a Payload portion (Frame Payload) of the second type of Data Frame, etc., based on the device type (DEVICE TYPE) of the controlled device, the second type (MANAGEMENT CMD TYPE), and the third command content (Cmd Data). For example: the device types of the controlled device are the dimmable device with the gesture sensing function, the second type is the gesture sensing function detected by the reading dimmable device, the third command content is that the indicator lamp is turned on, and the like, and the dimmable device with the gesture sensing function, the gesture sensing function detected by the reading dimmable device and the turn-on of the indicator lamp 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 the frame head or the frame tail according to a preset rule to generate a complete second class data frame.

Fig. 2 is a flowchart two of a data processing method according to an exemplary embodiment, and as shown in fig. 2, the data processing method is applied to a controlled device, and mainly includes the following steps:

In step 201, sending state information of the controlled device to an intelligent control center, so that the intelligent control center matches the controlled device with the controlled device according to the state information of the controlled device and the state information of the controlled device;

In step 202, receiving a matching result from the intelligent control center; the matching result is used for establishing communication connection between the control equipment and the controlled equipment.

Here, the controlled device (may also be 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 having a wireless transmission function such as radio frequency wireless transmission, infrared transmission, bluetooth transmission, wiFi transmission, or the like for receiving and executing commands such as control, management, or the like. In some embodiments, the controlled device may include: wall switch, single-way actuator, multi-way actuator, electric curtain, lamp, television, air conditioner, etc.

In an embodiment of the present disclosure, an intelligent control center may include: terminal device, gateway device, or cloud server, etc., e.g., mobile terminal or fixed terminal. Wherein, the mobile terminal may include: the mobile phone, the tablet computer, the notebook computer or the wearable device and other devices can also comprise intelligent home devices, such as an intelligent sound box and the like. The fixed terminal may include: desktop computers or smart televisions, etc. The intelligent control center may refer to a transfer device for performing processing such as matching, filtering or cutting on commands in a process of performing wireless transmission between 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, etc. that matches the control device. Of course, the transmission of the data frame between the controlled device and the control device may also be performed.

In a possible embodiment, the intelligent control center may also refer to a module or a chip with an intelligent control function, and may be embedded in a component of other devices, and the representation form of the intelligent control center is not specifically limited in this disclosure.

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 controlled device with the controlled device according to the state information of the controlled device and the state information of the controlled device. The state information of the controlled device may include address identification of the controlled device, motion, brightness, loudness, etc. 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 controlled device, detected control parameters, etc. For example: the intelligent control center matches the control equipment with a certain address identifier with the controlled equipment with a certain address identifier according to the considered or automatic setting according to a certain rule, and sends the address identifier information of the control equipment to the controlled equipment, so that the controlled equipment can be directly controlled by the control equipment after the controlled equipment stores the address identifier information of the control equipment, and once the matching relationship is established through the address identifier, all the control information of the control equipment can be applied to the controlled equipment. For example, if a control switch is turned on and turned off, once the switch and the controlled device are in a matching relationship, the controlled device is turned on above the switch and the controlled device is turned off below the switch. The intelligent control center determines that the state information of the controlled device A is from big to small in loudness, the state information of the controlled device B is from on to off in brightness, and the like, the state information of the control device a is from on to off, the state information of the control device B is from press level to gradually increase, and the like.

For example: the state information of the controlled device C carries the matching identifier 1, and the state information of the control device D also carries the matching identifier 1, so that the controlled device C and the control device D can be determined to be matched. In the embodiment of the disclosure, the device type carried in the state information of the controlled device can be controlled to be matched according to the device type carried in the state information of the controlled device. For example: the device type carried in the state information of the E controlled device is a channel type, the device type carried in the state information of the F controlled device is a single-on self-electricity type, the matching of the E controlled device and the F controlled device is determined through the preset matching of the channel type and the single-on self-electricity type, and the like.

After the intelligent control center obtains the matching result, the matching result can be respectively sent to the control equipment and the controlled equipment, so that the control equipment and the controlled equipment can directly transmit signals based on the matching result without passing through the intelligent control center.

In one possible embodiment, the controlled device may send the status information to the intelligent control center in a preset time unit, and in order to avoid an air collision when the plurality of controlled devices send the status information, the first time interval may be a random number. For example: the target identification of the controlled device is adopted as a random number source, and different time intervals can be generated due to different target identifications of each controlled device. The controlled equipment burning program can be used for burning different marks as a random number source, or the data read by an analog-digital converter which is not connected with any input can be used as a random number.

In another embodiment, to ensure that the intelligent control center receives status information accurately, the controlled device may transmit status information for multiple repetitions, such as 3-5 repetitions, etc. The controlled device can adopt preset time interval or random number for each time of sending repeated state information, and the generation of the random number can be the same as the generation algorithm of the random number, or different calculation modes can be adopted in the programming of the controlled device to ensure that the random numbers generated twice are different, so that air collision of data frames and the like can be better avoided. By adopting the mode, the method can improve the diversity of the state information sent by the controlled equipment, improve the matching efficiency and the like.

In the embodiment of the disclosure, the status information is sent to the intelligent control center within a preset time period (e.g., a seconds) when the controlled device is powered on, and the number of the status information repeatedly sent within c seconds is d at a second time interval (e.g., c seconds) when the status information is sent.

In another embodiment, after the controlled device is powered on, a delay may be performed, for example, a random delay is performed for a preset delay time period (for example, b seconds), and after b seconds are reached, the number of status information that is repeatedly sent in c seconds is d. The second time interval during which the controlled device repeatedly sends the status information may also be a random number, and the specific random manner is not specifically limited. For example: the controlled equipment is powered on for 60 seconds, randomly delays for a certain time, transmits a response data frame for 4 seconds, and repeatedly transmits 5 repeated state information in 4 seconds.

In another embodiment, after the controlled device determines that a certain function key is selected, a delay may be performed, for example, a random delay is performed for e seconds, and the length of time for transmitting the status information is f seconds, and the number of status information that is repeatedly transmitted in f seconds is g. The time interval at which the controlled device repeatedly transmits the status information may also be a random number, and the specific random manner is not particularly limited. For example: the controlled equipment is powered on for 30 seconds, randomly delays for a certain time, transmits a response data frame for 5 seconds, and repeatedly transmits 10 repeated state information in 5 seconds. By adopting the mode, the method can improve the diversity of the state information sent by the controlled equipment, improve the matching efficiency and the like.

When the communication connection between the control device and the controlled device is in a disconnected state, namely, the control device which is not paired with the controlled device, the control device can also directly receive a first trigger instruction sent by the control device, and then respond to the first trigger instruction to send state information of the controlled device to the intelligent control center according to a preset time interval for matching with the control device. The control device may be a control device that has established a connection with a controlled device, or may be a control device that has not established a connection with the controlled device, or may be a control device having a preset address (i.e., a control device of a specific address that is formulated in advance), or the like. By adopting the mode, the method can improve the diversity of the state information sent by the controlled equipment, improve the matching efficiency and the like.

For example: for a transmitting device, the length of DATA may be 1Byte. The transmitting device transmits data under a certain triggering condition, and the triggering condition can be that the transmitting device is electrified, or can transmit at fixed time, or the sensor data in the transmitting device changes. The transmitting means may load the content of the DATA based on the signal acquired by the sensor, and not load the sensor DATA if the sensor DATA is empty. And then reload TYPE data defining the TYPE of transmitting device, for example: the transmitting means may be defined as a switch, and the transmitting means may also be defined as a type of switch.

In some applications, the receiving executor is allowed to start the forwarding function to increase the transmission distance, but if forwarding is performed infinitely, the forwarding cannot be stopped or the occupied frequency band is too large, so that the transmission performance of the wireless system is affected, and therefore, it is important to set a certain forwarding stopping rule.
