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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.

It should be understood that the various steps recited in the method embodiments of the present disclosure may be performed in a different order, and/or performed in parallel. Moreover, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.

The term "including" and variations thereof as used herein is intended to be open-ended, i.e., "including but not limited to". The term "based on" is "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions for other terms will be given in the following description.

In the related art, a communication protocol used between the controller and the receiver has the characteristics of complex data format, complex communication mode, large code amount, large occupied space and the like, so that the communication protocol is generally suitable for communication between large-scale equipment and instruments. When used in small-sized equipment and instruments, the failure rate of communication between the small-sized equipment and the instruments is high due to the equipment conditions of the small-sized equipment and the instruments, and the communication efficiency between the small-sized equipment and the instruments is reduced.

To solve the problems in the related art, an embodiment of the present invention provides a communication method applied to a master device, please refer to fig. 1, where fig. 1 is a schematic flow diagram of the communication method applied to the master device, and as shown in fig. 1, the communication method provided by the embodiment of the present invention includes steps 101 to 104;

In step 101, in response to a setting instruction for a slave device, a data format compatible with the slave device is acquired.

The setting instruction is an instruction which is input by a user and used for controlling the slave equipment, and the instruction comprises an instruction which can control the slave equipment so as to enable the slave equipment to execute the function of the slave equipment. For example, when the master device is a controller and the slave device is a lamp, the setting command corresponds to a function of the lamp, including a switch control command, a brightness control command, a color temperature control command, a color control command, and the like.

It can be understood that, when the communication method provided in the embodiment of the present invention is applied to other devices, the setting instruction defined in the embodiment is not limited to the control instruction for controlling the lamp, and may also be a control instruction corresponding to a function of another device, which is not illustrated here.

In the embodiment of the present invention, when the master device is in communication connection with the slave device, the master device may automatically initiate a data format obtaining request to the slave device, so as to obtain the compatible data format fed back by the slave device, and store the data format, so as to recall the stored data format matched with the corresponding slave device when a setting instruction for the slave device is detected.

Specifically, when it is detected that the user inputs a setting instruction for the slave device on the master device, a data format acquisition request may be sent to the corresponding slave device, so as to acquire a data format compatible with the corresponding slave device.

In this embodiment, by obtaining the data format compatible with the slave device, it can be ensured that the information transmitted by the master device can be processed by the slave device, and the slave device is prevented from being unable to process the information or command transmitted by the master device, thereby improving the communication efficiency between the master device and the slave device.

In some cases, the master device may communicate directly with the slave device. In other cases, the master device may communicate via an intermediary. For example, a master device communicates with a slave device on a wireless network provided by an access point via a wireless network access point.

In some embodiments, communication with a slave device may be limited to authorized master devices. In particular, by establishing a pairing between the master device and the slave device to indicate that the user wishes the master device to be able to control the slave device, and the master device with which the pairing has been established can be considered authorized for that slave device. After the pairing is established, the slave device can verify whether the received communication is from the paired master device or another device, and the slave device can reject any communication that is not from the paired master device (and vice versa). For example, when a previously paired slave device and master device reconnect, they may verify the previous pairing and generate a session-specific encryption key for communicating within the pairing-verified session. In some embodiments, multiple master devices may establish pairings with the same slave device, one or more master devices may also establish pairings with multiple slave devices, and a slave device may accept communications from any master device with which it is paired and respond while rejecting or ignoring communications from unpaired master devices.

And 102, generating a setting request to be sent according to the setting instruction.

After a setting instruction for controlling the slave device, which is input by a user on the master device, is acquired, the master device automatically generates a setting request corresponding to the setting instruction according to the setting instruction. Specifically, the setting instruction may include an instruction for controlling the slave device to execute one operation, or may include an instruction for controlling the slave device to execute a plurality of operations, and then the master device generates a corresponding request for each operation command according to the instructions, so as to form a setting request to be sent. For example, the setting instruction input by the user is: and turning on the light, reducing the brightness and adjusting the color to the warm color, generating a light-on request, a brightness reduction request and a color adjustment to the warm color request by the main equipment, and combining and packaging the requests into a setting request.

In some embodiments, when the slave device is a luminaire, the master device may generate a corresponding setting request in conjunction with the luminance characteristics and the hue characteristics of the luminaire. For example, the luminance characteristic may have an integer value in the range of 0 to 100 to indicate the luminance level as a percentage of the maximum luminance supported by the luminaire. The tone characteristic may have floating point values that specify the tone in a range of 0 to 360 degrees, and converting values in degrees to physical tones may follow standard color modeling practices. Therefore, after the slave device receives the setting request generated by the master device, the setting operation corresponding to the setting request can be accurately executed, so that the communication efficiency is improved, and the user experience is improved.

Step 103, assembling the setting information according to the device information and the setting request of the main device.

In this embodiment, the step of assembling the setting information according to the device information and the setting request of the master device specifically includes: acquiring equipment identification information corresponding to the main equipment and command information corresponding to the setting request; and assembling to obtain the setting information according to the identification information and the command information.

The device identification information of the master device is a start packet as setting information, which has an identification function for the slave device to identify the device information of the master device with which communication is performed. Specifically, each master device has a unique device identifier, and after the master device and the slave device are paired, the slave device only needs to detect the device identifier information of the master device communicating with the slave device, so as to determine whether the master device communicating with the slave device is the paired master device, that is, detect whether the master device is an authorized master device. Thereby, the slave device can reject a request of a master device with which it is not paired. In addition, the start packet may further include checksum data including an accumulated sum of all fields of all data except the start packet in the setting information.

Specifically, the command information includes at least one command data packet, and the command data packet includes command type information and a command data body, where one command data packet corresponds to one command request. Before the step of obtaining the device identification information corresponding to the master device and the command information corresponding to the setting request, the communication method provided in this embodiment further includes: acquiring a function name of a slave device with a function; generating corresponding command type information and a command data body according to the setting request and the function name; command type information and a command data body are taken as command information.

In the present embodiment, the command type information may be data defined according to a function name. For example, when the slave device is a lamp, corresponding command type information, such as a color temperature function of a lamp corresponding to CCT, a color customization function of a lamp corresponding to RGBWW, a Switch function of a lamp corresponding to Switch, etc., is defined according to the characteristics and the corresponding function names of the lamp. Further, since the slave device, that is, the lamp has version information, failure information, battery status information, and the like, which can be detected and obtained by itself, the command type information defining the slave device may also be command type information that obtains the own status information of the slave device.

Specifically, please refer to the command type information shown in table 1 below, which defines that most of the light fixtures have command type information corresponding to functions. Table 1 shows the serial number, name, and description of the command type information, and the master device may generate corresponding command type information according to the content defined in table 1 and the setting instruction input by the user.

In another embodiment, the host device may further generate a corresponding command data body according to a setting instruction input by a user and command type information generated by the host device, where the command data body mainly includes data for performing command type control on each function. The command data body may include command type information and operation information to be executed, for example, when the setting information is information for setting a switch of a lamp, the command data body in the setting information is "0X 0C on", which indicates that the state of the control switch is an on state.

In some embodiments, the setting information further includes attribute information to be a packet of the setting information. The step of obtaining the setting information by assembling according to the identification information and the command information specifically includes: acquiring protocol identification information of the primary equipment which carries out communication at this time and frequency information of carrying out data communication with the secondary equipment; according to the frequency information, generating serial number information for communication with the slave equipment at this time; and taking the protocol identification information and the sequence number information as attribute information, and assembling to obtain setting information according to the attribute information, the identification information and the command information.

The protocol identification information is used for determining the current protocol version of the master equipment, and when the protocol version of the master equipment is different from that of the slave equipment, the version error prompt is triggered to prompt the master equipment or the slave equipment to update the protocol version. Specifically, a version error prompt is sent to the end with the lower protocol version. In addition, when the slave device is the controlled end and the protocol version of the slave device is higher than that of the master device, the protocol version of the slave device is compatible with the protocol version with the lower version, that is, the slave device can execute corresponding operation according to the data transmitted by the master device, and does not need to execute the corresponding operation after updating. However, when the protocol version of the slave device is low, the protocol version needs to be upgraded first, and then the corresponding operation is executed according to the setting information.

The number information is the number of data sent by the master device and the slave device in the communication process, and the number information +1 is used as the serial number information of the communication with the slave device at this time, so that the communication information between the master device and the slave device is recorded. In this embodiment, the value range of the sequence number information is 0 to 65535.

In other embodiments, the attribute information further includes a data length of the attribute information, and a data length of the entire setting information. Specifically, the data length of the attribute information is 0 to 255, and the data length of the entire setting information is less than 1024 bytes.

In order to better operate the communication method provided by the embodiment of the present invention in a small device or an apparatus, after the step of assembling the setting information according to the identification information and the command information, the communication method provided by the embodiment further includes: detecting the data length of the setting information; and if the data length is larger than the preset data length, generating a setting information error prompt and suspending transmission of the setting information.

Since the data length of the entire setting information needs to be smaller than 1024 bytes, the preset data length may be set to 1024 bytes. Thus, when the data length of the setting information is larger than 1024 bytes, generating a setting information error prompt and suspending transmission of the setting information; otherwise, the setting information is continuously transmitted. Optionally, the preset data length may also be set to a value smaller than 1024 bytes, so as to improve the efficiency of data transmission.

In an alternative embodiment, the attribute information further comprises reply time capability information to control the reply capability of the slave device. For example, when the slave device does not need to respond, information for prohibiting response may be added to the attribute information to prohibit the slave device from responding to the current setting information (conversely, the slave device may be permitted to respond).

And step 104, repeatedly transmitting the setting information to the slave device in the data format compatible with the slave device within the transmission duration until the slave device executes corresponding setting operation according to the setting information.

In the related art, a communication protocol of a data format is simply customized, and the problems of high communication failure rate and no reissue mechanism exist, so that the embodiment of the invention repeatedly transmits the setting information to the slave device within the transmission duration, and the transmission of the setting information is not stopped until the slave device is detected to execute the corresponding setting operation.

Specifically, the transmission duration is the time between the start of transmission and the execution of the corresponding setting operation by the slave device. By repeatedly transmitting the setting information until the slave device executes the corresponding operation, the problems of high communication failure rate and no reissue mechanism in the related technology can be solved, so that the communication efficiency between the master device and the slave device is effectively improved. For example, after the master device transmits the setting information, it is detected whether the slave device receives the response every a preset detection time, where the preset detection time may be set to 200ms, 300ms, 350ms, and so on, and if the master device does not receive the response of the slave device in the preset detection time, the setting information is transmitted to the slave device again, and the setting information is cyclically transmitted to the slave device until the slave device completes the response.

In order to improve the communication efficiency, if the master device of this embodiment does not receive the response from the slave device after continuously presetting the transmission times, where the preset transmission times may be set to 3 times, 4 times, 5 times, and the like, when the response is not received after the preset transmission times, the communication failure may be directly determined, and a communication failure identifier is displayed on the master device to remind the user of the communication failure, thereby avoiding that the master device continuously sends data all the time, and saving the communication cost.

It should be noted that the slave device may also respond to the setting information transmitted by the master device, and when the setting information transmitted by the master device includes information indicating that the response is allowed, the slave device may respond. When the slave device responds to the setting information transmitted by the master device, the serial number information in the setting information, for example, N, needs to be acquired first, and when the slave device responds, the serial number information with the serial number N needs to be added to the responded information. That is, when the master device or the slave device replies to the peer device, the corresponding serial number information must be added to the reply information. Therefore, the master device or the slave device can be prevented from responding to wrong information or receiving wrong response information, so that the communication failure rate is effectively reduced, and the communication efficiency between the master device and the slave device is improved.

As a preferred embodiment of the present invention, in this embodiment, the setting information transmitted to the slave device by the master device includes three types of data, where the first type of data is a start packet, that is, device information (including device identification information and checksum data) of the master device; the second data is a packet, i.e. attribute information of the master device (including protocol identification information, sequence number information, data length of the attribute information, and data length of the entire setting information); the third type of data is a command packet, i.e., command information (including command type information and a command data body). It should be noted that the number of packets of the first data and the second data, i.e., the start packet (device information of the master device) and the information packet (attribute information of the master device), in the setting information is only one, and the number of packets of the third data, i.e., the command packet (command information), is variable (each command packet contains only one setting request). Therefore, the whole data length of the setting information can be flexibly processed according to the command data packet, so that the setting information provided by the embodiment can be applied to various types (small, medium and large types) of equipment and instruments, and the communication efficiency of the communication method provided by the embodiment is effectively improved. Specifically, the setting information in this embodiment is shown in table 2 below.

TABLE 2

In order to solve the same technical problem, an embodiment of the present invention further provides a communication method applied to a slave device, please refer to fig. 2, fig. 2 is a schematic flow chart of the communication method applied to the slave device according to the embodiment of the present invention, and as shown in fig. 2, the communication method according to the embodiment of the present invention includes steps 201 to 204;

step 201, when detecting the communication connection with the master device, sending the data format compatible with the slave device to the master device.

In some embodiments, the slave device may automatically send a data format compatible with the slave device to the master device upon detecting a communication connection with the master device. In other embodiments, the slave device may also feed back a data format compatible with the slave device to the master device when detecting or receiving a setting request sent by the master device. The slave device sends the data format information to the master device, so that the master device can unify the data format, and the data transmitted by the subsequent master device is convenient to be the data with the data format compatible with the slave device.

Step 202, receiving the setting information transmitted by the master device.

Step 203, checking the setting information.

In this embodiment, the step of performing verification processing on the setting information specifically includes: acquiring a function name of a slave device with a function; detecting whether command information contained in the setting information corresponds to the function name; if yes, the verification processing is determined to pass.

Wherein, detecting whether the command information included in the setting information corresponds to the function name is only one of the verification methods. The identity information of the master device can be determined by checking the device identification information of the master device. In addition, whether the master device communicating with the slave device is a previously paired device can be determined by checking the encryption key of the master device.

Similarly, when the master device receives the information transmitted by the slave device, the information transmitted by the slave device needs to be verified, and the transmitted information can be processed after the verification is passed.

It should be understood that the way of checking the information transmitted by the master/slave device is not limited to the above mentioned way, and other ways of checking the identity information of the master/slave device can also be within the scope of the present invention, which is not limited herein.

And step 204, after the verification processing is passed, executing corresponding setting operation according to the setting information.

In this embodiment, after the verification process passes, it may be determined that the master device and the slave device are in a pairing relationship, that is, the master device is an authorized device and can be used to control the slave device. At this time, the slave device will parse the setting information transmitted by the master device. Specifically, since the setting information sent by the master device is mainly used for controlling the functions of the slave device, the slave device stores command type information corresponding to the functions of the slave device, and specifically, when the slave device is a lamp, the slave device stores the command type information in table 1 of the above embodiment. Therefore, the setting information transmitted by the main equipment can be analyzed, and corresponding setting operation is executed according to the analyzed setting request.

As an optional embodiment, when the setting information transmitted by the master device contains information that indicates that a response is allowed, the slave device may also respond to the setting information transmitted by the master device. Specifically, the slave device mainly responds with the information shown in table 3 below.

TABLE 3

As shown in table 3 above, the slave device mainly responds to the write command, specifically, responses to normal control and upgrade. It will be appreciated that when the master device is responding to the information transmitted by the slave device, it will also respond with the content shown in table 3 above.

As an optional embodiment, the embodiment of the present invention may further set the master device and the slave device, so that both the master device and the slave device can be used as a master or a slave, thereby effectively improving user experience. Specifically, a master-slave mode function is set on all the devices, and a user selects the master-slave mode of each device. For example, when the slave device is set to the master mode as the master, other devices such as the master device will automatically switch to the slave mode as slaves, thereby completing the setting of the master-slave mode. In the embodiment, the host sends the broadcast packet data, and the slave receives the broadcast packet data and then responds to the device address of the host, so that the host can specify the address to communicate with the slave after acquiring the device address of the slave, thereby realizing the master-slave mode.

According to the method described in the foregoing embodiment, the embodiment will be further described from the perspective of a communication device, which may be specifically implemented as a stand-alone entity, or may be implemented by being integrated in an electronic device, such as a terminal, where the terminal may include a mobile phone, a tablet computer, and the like.
