Referring to fig. 2, in a first embodiment of the remote control method for smart home of the present invention, the remote control method for smart home includes:
step S100, receiving a user instruction, wherein the user instruction comprises one or more information instruction data packets;
currently, in conventional IMS (IP Multimedia Subsystem, IP multimedia system) communication, a dual tone multi frequency DTMF (Dual Tone Multi Frequency ) mode is adopted for signaling-based control, and DTMF signals are transmitted based on an intranet or a private network, so that reliability can be basically ensured. But today in the development of the internet of things, the terminal of the internet of things basically adopts a WIFI (wireless network) mode for access, the terminal of the internet of things to a platform belong to a public network for access, the network quality cannot be ensured, DTMF signals are easy to lose, and therefore remote control based on communication cannot be realized, and if the remote control fails. The DTMF signal is a user signaling between the telephone and the exchange, and unlike the pulse signal, each key information in the DTMF signal includes two signals of two frequencies transmitted simultaneously, wherein one signal of the two frequencies is a low frequency signal and the other signal of the two frequencies is a high frequency signal.
In order to reduce the possibility of DTMF signals being lost in the public network, the present invention proposes an embodiment. In this embodiment, the remote control method for smart home is applied to a multimedia communication platform, where the multimedia communication platform is in communication connection with a mobile phone of a user, and the multimedia communication platform is also in communication connection with terminals of the internet of things. When the user wants to control the smart home, the user instruction can be sent to the multimedia communication platform by inputting a key on the mobile phone, the user instruction comprises one or more information instruction data packets containing DTMF signals, and the multimedia communication platform can receive the one or more information instruction data packets containing DTMF signals through the public network.
Specifically, the internet of things terminal may include an access control system, an air conditioner, a television, or other internet of things home internet of things terminals. When the terminal of the Internet of things is an access control system, namely the access control system integrates a lightweight control protocol, the access control system is accessed into a communication network through a public network. When a visitor passes through the access control system, the visitor needs to input a room number to be accessed in the access control system, the access control system generates an access request according to the input room number, then the access request is converted into a corresponding owner mobile phone number, and a call is initiated to a user through a software development kit built in the access control system according to the mobile phone number. After the owner receives the call, if the owner considers that the door can be opened, the door opening password can be input through the dial plate, and the door opening password is the information instruction data packet and is transmitted to the multimedia communication platform in a DTMF mode. When the terminal of the Internet of things is an air conditioner, namely the air conditioner integrated lightweight control protocol, the terminal is connected into a communication network through a public network. If the user wants to adjust the switch of the air conditioner or adjust the temperature of the air conditioner, the user can dial a preset intelligent home service number, after the number is connected, the user can interact with the multimedia communication platform in a mode of continuously inputting the mobile phone keys, and an information instruction data packet is sent to the multimedia communication platform in a DTMF mode, so that the control of the air conditioner is realized.
Step S200, analyzing the information instruction data packet to obtain an information instruction data block;
in this embodiment, after the multimedia communication platform receives the information instruction data packet, the information instruction data packet needs to be parsed to obtain the information instruction data block. Each information instruction data packet can obtain an information instruction data block after being analyzed. The number of the information instruction data packets can be one or a plurality of. If there are multiple information instruction data packets, the multiple information instruction data packets together form a complete user instruction. The information instruction data block is obtained by analyzing an information instruction data packet in a preset mode, and at least comprises a DTMF value.
Because the information instruction data packet in the scheme is a DTMF signal input through a mobile phone keyboard, in a transmission mode of the DTMF signal, 8 audio signals are divided into 2 groups, 4 are arranged in each group, one group is a low-frequency group consisting of 4 low-frequency signals, and the other group is a high-frequency group consisting of 4 high-frequency signals. The signals in the low frequency group and the high frequency signals in the high frequency group are combined two by two to generate 16 combination modes, wherein the 16 combination modes represent 16 keys, namely 0-9, #, x and the like on the dial of the mobile phone respectively. For example, "4" is a superposition of 770HZ and 1209HZ signals, and "3" is a superposition of 697HZ and 1477HZ signals, etc. Therefore, each time the user presses a key on the mobile phone dial, a combination of high-frequency and low-frequency sinusoidal signals is sent to the multimedia communication platform, and after receiving the information instruction data packet, the multimedia communication platform parses the information instruction data packet to obtain the keys corresponding to the frequency combinations.
And step S300, packaging the information instruction data block into a second instruction data packet, and sending the second instruction data packet to an Internet of things terminal, so that the Internet of things terminal executes the operation corresponding to the second instruction data packet.
In this embodiment, one user instruction includes one or more information instruction data packets, and after the multimedia communication platform receives and parses the information instruction data packets, an information instruction data block is obtained. If the information instruction data packet contained in the same user instruction is one, an information instruction data block can be obtained through analysis, the information instruction data block is packaged into a second instruction data packet after analysis, and the second instruction data packet is sent to the Internet of things terminal corresponding to the user instruction, so that the Internet of things terminal executes corresponding operation according to the second instruction data packet; if the number of the information instruction data packets contained in the same user instruction is multiple, multiple information instruction data blocks can be obtained through analysis, and because the multiple information instruction data blocks belong to the same user instruction, the multiple information instruction data blocks are required to be combined, then the combined multiple information instruction data blocks are packaged into a second instruction data packet, and the second instruction data packet is sent to the internet of things terminal corresponding to the user instruction, so that the internet of things terminal executes corresponding operation according to the second instruction data packet. The second instruction data packet is a data packet packaged by a packaging mode set in advance by a person skilled in the art according to a preset packaging rule, the specific packaging mode can be changed at any time according to user requirements, and the second instruction data packet can be packaged according to a PPP/HDLC protocol or a LAPS protocol.
In this embodiment, the step of sending the second instruction packet to the terminal of the internet of things includes: judging whether a successful feedback signal is received and sent within a preset time length; if the successful feedback signal is received and sent within the preset time length, the second instruction data packet is not sent to the terminal of the Internet of things any more; if the preset duration does not receive the successful feedback signal, the second instruction data packet is sent to the terminal of the Internet of things again.
In this embodiment, for example, after the terminal of the internet of things receives the second instruction data packet sent by the multimedia communication platform, a feedback signal that the receiving and sending are successful is fed back to the multimedia communication platform. After the first second instruction data packet is successfully sent, the multimedia communication platform can judge whether a sending success feedback signal is received within a preset time period, if the multimedia communication platform receives the sending success feedback signal within the preset time period, the second instruction data packet is not sent to the internet of things terminal any more, and if the multimedia communication platform does not receive the sending success feedback signal within the preset time period, the second instruction data packet is sent to the internet of things terminal any more. The preset time length is a time length set in advance by a person skilled in the art according to the transmission process of the data packet, and can be adjusted at any time according to actual conditions.
In addition, because the user command has timeliness, if the multimedia communication platform does not receive the successful feedback signal, after the preset command effective duration, the second command data packet is stopped to be sent. The time length of the effective preset command is longer than the preset time length, and the time length of the effective preset command is set in advance by a person skilled in the art according to the household use condition and can be adjusted at any time according to the actual condition.
The scheme provides a control method of an intelligent home, and compared with a traditional intelligent home control method, the scheme provides a lightweight multimedia communication scheme for the intelligent home, wherein the scheme comprises a software development kit and a multimedia communication platform, wherein the software development kit is built in the intelligent home and is used for communication. According to the scheme, the remote control capability based on communication is provided, the size of the data packet is smaller than that of the traditional data packet, so that the loss rate of the data packet is reduced, meanwhile, after the data packet is sent, whether the data packet is sent again is judged through feedback of the terminal of the Internet of things, if a successful feedback signal is not received by the multimedia communication platform within a preset time period, the second instruction data packet is sent again, the risk of data loss is further avoided, and the reliability in the instruction transmission process is improved.
Further, according to the first embodiment of the present invention, in another embodiment of the present invention, the step of parsing the information instruction packet includes:
and unpacking and compressing the information instruction data packet to obtain an information instruction data block.
In this embodiment, the multimedia communication platform may perform signal conversion on the user command sent by the user, that is, convert the information command packet into the second command packet. Specifically, in the process of parsing the information instruction data packet, the information instruction data packet needs to be unpacked, and the data packet is compressed while unpacking, so as to obtain the information instruction data block. Through the analysis process, invalid fields in the information instruction data packet can be filtered, the length of the data packet is reduced, the packet loss rate during data packet transmission is reduced, and the data packet can be conveniently recombined and transmitted.
Specifically, the step of unpacking and compressing the information instruction data packet to obtain an information instruction data block includes:
analyzing the mark type of the DTMF stream in the information instruction data packet;
analyzing the RTP stream in the information instruction data packet, and extracting the sub-data packet corresponding to the mark type from the RTP stream;
and extracting a DTMF value from the sub-data packet and encoding the DTMF value to obtain an information instruction data block.
In this embodiment, the information instruction packet includes two data streams, namely a DTMF stream and an RTP (Real-time transport protocol) stream. In some embodiments, in the process of parsing the information instruction packet, firstly, parsing a flag type of a DTMF stream in an SDP in the SIP information instruction packet, then decoding an audio RTP stream, extracting a sub-packet corresponding to the flag type, and then parsing the sub-packet according to RFC2833 protocol, so as to extract an Event ID value and an End of Event identification bit in the sub-packet to obtain a DTMF value in the sub-packet. In some embodiments, the flag type is a number. And coding the obtained DTMF value by an And-SIP protocol to obtain the information instruction data block. In particular, various methods may be applied to obtain DTMF values from SIP information instruction packets, including at least the SIP info method, RFC2833 method, and INBAND method.
In one embodiment, the step of encapsulating the information instruction data block into a second instruction data packet includes:
acquiring a sequence number value in the user instruction;
and packaging the information instruction data block and the sequence number value into the second instruction data packet.
In this embodiment, the different information command data packets include different serial number values besides different DTMF signals, and the different serial number values mean that the user command acts on different smart home. For example, the object with the serial number of 01 time representing the user instruction is an air conditioner, the object with the serial number of 04 time representing the user instruction is a curtain, and the object with the serial number of 21 time representing the user instruction is a desk lamp. The corresponding relation between the serial number value and the terminal of the Internet of things can be set by a user. Before the second instruction packet is packaged, the sequence number value needs to be extracted from the user instruction, and then the number of information instruction data blocks contained in the parsed user instruction is judged. If the analyzed user instruction only comprises one information instruction data block, the extracted sequence number value is added to the information instruction data block, and the information instruction data block is packaged into a second instruction data packet. If the analyzed user instruction contains a plurality of information instruction data blocks, the information instruction data blocks are combined into an information instruction data set, and then the extracted sequence number value is added to the information instruction data set and packaged into a second instruction data packet. The serial number value can help the user to realize accurate control to intelligent house, avoids data transmission to take place the disorder.
In one embodiment, the step of encapsulating the information instruction data block and the sequence number value into a second instruction data packet comprises:
if a plurality of information instruction data packets exist, combining the information instruction data blocks to obtain an information instruction data set;
and packaging the information instruction data set and the sequence number value into the second instruction data packet.
In this embodiment, after the information instruction data packet is unpacked and compressed into the information instruction data block, the information instruction data block needs to be repackaged into the data packet, so that the user instruction can be sent to the corresponding internet of things terminal through the network.
In the user instruction, the same user instruction comprises one or more different information instruction data packets, and because each information instruction data packet can be analyzed to obtain one information instruction data block, the analyzed user instruction comprises one or more information instruction data blocks. If the analyzed user instruction only comprises one information instruction data block, the second instruction data packet can be packaged after the sequence number value is added to the information instruction data block. If the parsed user instruction contains a plurality of information instruction data blocks, the data blocks together form the user instruction, so that the plurality of information instruction data blocks need to be combined into an information instruction data set, and then a sequence number value is added to the information instruction data set and packaged into a second instruction data packet. The second instruction data packet is a data packet set by a person skilled in the art according to a preset rule encapsulation rule, wherein the second instruction data packet is used for transmitting a user instruction sent by a user to the internet of things terminal from the multimedia communication platform through a network so as to assist the user in controlling the internet of things terminal.
In an embodiment, the step of combining the information instruction data blocks to obtain an information instruction data set includes:
copying each information instruction data block according to preset copying times to obtain a copied data block;
setting the information instruction data block and a copy data block corresponding to the information instruction data block as target data blocks; and determining the information instruction data set according to the target data block.
In this embodiment, in order to obtain a plurality of identical second instruction packets, after the information instruction packets are parsed to obtain information instruction data blocks, the information instruction data blocks need to be copied according to a preset number of copying times to obtain duplicate data blocks identical to the information instruction data blocks, then the identical information instruction data blocks and duplicate data blocks are set as target data blocks, and an information instruction data set is determined according to the target data blocks.
In the user instruction, the same user instruction comprises one or more different information instruction data packets, and because each information instruction data packet can be analyzed to obtain one information instruction data block, the analyzed user instruction comprises one or more information instruction data blocks. In some embodiments, the user instruction includes only one block of information instruction data, the block of user instruction data is replicated to obtain one or more duplicate blocks of data that are identical to the block of user instruction data, and the blocks of information instruction data and duplicate blocks of data are set as target blocks of data, where each target block of data can be encapsulated as a second instruction packet. In other embodiments, the user instruction includes a plurality of different information instruction data blocks, and if the user instruction includes the plurality of different information instruction data blocks, the information instruction data blocks are copied the same number of times, and then each information instruction data block obtains one or more corresponding copied data blocks, and each completely same information instruction data block and copied data block are set as a group of target data blocks, and the number of second instruction data packets obtained by encapsulation is the same as the number of target data blocks in each group. The preset copying times are set in advance by a person skilled in the art according to actual rules, and can be adjusted at any time according to specific conditions.
According to the scheme, the information instruction data block is copied, one or more groups of multiple completely identical target data blocks can be generated, and multiple completely identical second instruction data packets are generated, so that the phenomenon of packet loss when only one second instruction data packet exists is avoided, and the stability of signal transmission is enhanced.
In one embodiment, the step of determining the information instruction data set from the target data block comprises:
and sequentially extracting a target data block corresponding to each information instruction data packet, and combining the extracted target data blocks to obtain an information instruction data set.
In this embodiment, if only one information instruction packet exists in the user instruction, it is not necessary to combine the target data blocks; if there are a plurality of information instruction data packets, the target data block needs to be recombined after the information instruction data block is copied. Because the target data block corresponding to the same information instruction data packet is one type, the information instruction data blocks are multiple, and the steps of combining are specifically as follows: one is extracted from each target data block to be combined to obtain an information instruction data set. Thereafter, the specific steps of the combination are repeated until all the target data blocks are combined into the information instruction data set. The process of converting the information instruction packet into the second instruction packet may take a variety of forms, one of which is described below.
In one embodiment, as shown in fig. 3, the user instruction includes two information instruction data packets, named Frame1 And Frame2, respectively, firstly analyzes the flag type of the DTMF stream in Frame1 to obtain flag type 106, then decodes the audio RTP stream in Frame1, extracts the sub-data packet with flag type 106, then analyzes the extracted sub-data packet according to RFC2833 protocol, extracts the Event ID value And the End of Event identification bit to obtain the DTMF value, and then encodes the obtained DTMF value by the add-SIP protocol to obtain the bitsfream 1 data block. And obtaining the Bitstream2 data block by the Frame2 data packet according to the analysis mode of the Frame1 data packet. The preset number of copies in this embodiment is 1. Therefore, the bitsfream 1 data block is copied into a bitsfream 1+ data block, meanwhile, the bitsfream 2 data block is copied into a bitsfream 2+ data block, wherein the bitsfream 1 data block and the bitsfream 1+ data block are a group of target data blocks corresponding to a Frame1 data Packet, the bitsfream 2 data block and the bitsfream 2+ data block are another group of data blocks corresponding to a Frame2 data Packet, then the bitsfream 1 data block and the bitsfream 2 data block are combined, then a sequence number value corresponding to a user instruction is added, packaging is conducted to obtain a second instruction data Packet, the second instruction data Packet is named as Packet1, the bitsfream 1+ data block and the bitsfream 2+ data block are combined, then a sequence number value corresponding to the user instruction is added, and packaging is conducted to obtain a second instruction data Packet2. The Packet1 and the Packet2 contain the same user instruction, so that even if the Packet1 is lost in the process of being sent to the terminal, the terminal can still acquire the user instruction through the Packet2.
By means of copying the original information instruction data blocks and recombining the original information instruction data blocks into a plurality of identical instruction data packets, guarantee can be added for transmission of user instructions, and data loss in the transmission process of the user instructions is reduced.
As shown in fig. 4, the present invention further provides a remote control device for an intelligent home, where the remote control device for an intelligent home includes:
