Various embodiments of the method of the present invention are presented in terms of the above-described hardware architecture.
Referring to fig. 2, in a first embodiment of the remote control method for smart homes of the present invention, the remote control method for smart homes includes:
step S100, receiving a user instruction, wherein the user instruction comprises one or more information instruction data packets;
at present, in a conventional IMS (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 guaranteed. However, in the development of the internet of things today, the internet of things terminal basically adopts a WIFI (wireless network) mode for access, the internet of things terminal is accessed to a platform from a public network, network quality cannot be guaranteed, DTMF signals are easily lost, and therefore remote control based on communication cannot be achieved, and if the remote control fails. The DTMF signal is a user signaling between a telephone and an exchange, and is different from a pulse signal in that each key information in the DTMF signal comprises two frequency signals which are simultaneously transmitted, wherein one frequency signal is a low-frequency signal, and the other frequency signal is a high-frequency signal.
In order to reduce the possibility of losing DTMF signals in the public network, the invention provides an embodiment. In this embodiment, the remote control method for the smart home is applied to a multimedia communication platform, 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 a user wants to control the smart home, a user instruction can be sent to the multimedia communication platform in a mode of inputting keys 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 the DTMF signals through the public network.
Specifically, the internet of things terminal can comprise an access control system, an air conditioner, a television or other internet of things home internet of things terminals. When the internet of things terminal is an access control system, the access control system integrates a lightweight control protocol and accesses 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 into the access control system, the access control system generates an access request according to the input room number, then converts the access request into a corresponding mobile phone number of an owner, and calls 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, the door opening password is an information instruction data packet, and the information instruction data packet is transmitted to the multimedia communication platform in a DTMF mode. When the internet of things terminal is an air conditioner, the air conditioner integrates a lightweight control protocol and 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 keys of the mobile phone, 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 analyzed to obtain an information instruction data block. And each information instruction data packet is analyzed to obtain an information instruction data block. The number of the information instruction packets may be one or more. If the number of the information instruction data packets is multiple, the multiple information instruction data packets jointly form a complete user instruction. The information instruction data block is obtained by analyzing an information instruction data packet in a preset mode, wherein the information instruction data block 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 the transmission mode of the DTMF signal, audio signals with 8 frequencies are divided into 2 groups, each group is 4, 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 pairwise to generate 16 combination modes, and the 16 combination modes represent 16 keys, namely represent keys 0-9, #, #andthe like on a mobile phone dial respectively. For example, "4" is a superposition of 770HZ and 1209HZ signals, "3" is a superposition of 697HZ and 1477HZ signals, and so on. Therefore, each time a user presses a key on the dial plate of the mobile phone, a high-frequency and low-frequency sinusoidal signal combination is sent to the multimedia communication platform, and after receiving the information instruction data packet, the multimedia communication platform analyzes the information instruction data packet to obtain keys corresponding to the frequency combinations.
Step S300, packaging the information instruction data block into a second instruction data packet, and sending the second instruction data packet to the 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 command includes one or more information command data packets, and after receiving and analyzing the information command data packets, the multimedia communication platform obtains information command data blocks. If the number of the information instruction data packets 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 information instruction data packets contained in the same user instruction are multiple, multiple information instruction data blocks can be obtained through analysis, the multiple information instruction data blocks all belong to the same user instruction, and therefore the multiple information instruction data blocks need to be combined, the multiple combined 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 can execute corresponding operation according to the second instruction data packet. The second instruction data packet is a data packet which is encapsulated in an encapsulation mode set in advance by a person skilled in the art according to a preset encapsulation rule, the specific encapsulation mode can be changed at any time according to user requirements, and the second instruction data packet can be encapsulated according to a PPP/HDLC protocol or an LAPS protocol.
In this embodiment, the step of sending the second instruction packet to the internet of things terminal includes: judging whether a successful sending feedback signal is received or not within a preset time length; if the successful sending 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; and if the preset duration does not receive the feedback signal which is successfully sent, sending the second instruction data packet to the Internet of things terminal again.
In this embodiment, after the terminal of the internet of things receives the second instruction data packet sent by the multimedia communication platform, a feedback signal of successful sending and receiving is fed back to the multimedia communication platform. After the first second instruction data packet is successfully sent, the multimedia communication platform judges whether a feedback signal of successful sending is received within a preset time length, if the multimedia communication platform receives the feedback signal of successful sending within the preset time length, the multimedia communication platform does not send the second instruction data packet to the internet of things terminal any more, and if the multimedia communication platform does not receive the feedback signal of successful sending within the preset time length, the multimedia communication platform sends the second instruction data packet to the internet of things terminal again. The preset time length is a time length preset 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 instruction has timeliness, if the multimedia communication platform does not receive the feedback signal of successful sending all the time, after the instruction effective duration is preset, the sending of the second instruction data packet is also stopped. The preset instruction effective duration is longer than the preset duration, is a time length preset 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.
Compared with the traditional intelligent home control method, the scheme provides a lightweight multimedia communication scheme oriented to the intelligent home, and the scheme comprises a software development kit and a multimedia communication platform which are built in the intelligent home and used for communication. The scheme provides a remote control capability based on communication, the size of a data packet in the scheme is smaller than that of a 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 the feedback of the Internet of things terminal, if the multimedia communication platform does not receive a feedback signal of successful sending within a preset time length, a 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, based on the first embodiment of the present solution, in another embodiment of the present solution, 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 a user instruction sent by a user, that is, convert the information instruction data packet into a second instruction data 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 being unpacked, 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 when the data packet is sent is reduced, and the data packet is conveniently recombined and sent.
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 an RTP stream in the information instruction data packet, and extracting a sub-data packet corresponding to the mark type from the RTP stream;
extracting DTMF values from the sub data packets and coding the DTMF values to obtain information instruction data blocks.
In this embodiment, the information instruction packet includes two data streams, i.e., a DTMF stream and an RTP (Real-time Transport Protocol) stream. In some embodiments, in the process of parsing the information instruction packet, the flag type of the DTMF stream in the SDP in the SIP information instruction packet is parsed first, then the audio RTP stream is decoded, the sub-packet corresponding to the flag type is extracted, and then the sub-packet is parsed according to the RFC2833 protocol, so as to extract the Event ID value and the End of Event identification bit in the sub-packet to obtain the DTMF value in the sub-packet. In some embodiments, the flag type is a number. And carrying out the encoding of the Add-SIP protocol on the acquired DTMF value to obtain an information instruction data block. Specifically, obtaining DTMF values from the SIP information instruction packet may apply various methods including at least the SIP info method, the RFC2833 method, and the inbound method.
In one embodiment, the step of encapsulating the information instruction data block into a second instruction data packet includes:
acquiring a serial 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, different information instruction data packets include different sequence number values in addition to different DTMF signals, and the different sequence number values mean that a user instruction acts on different smart homes. For example, the object representing the action of the user instruction is an air conditioner when the serial number value is 01, the object representing the action of the user instruction when the serial number value is 04 is a curtain, and the object representing the action of the user instruction when the serial number value is 21 is a table lamp. The corresponding relation between the serial number value and the internet of things terminal can be set by a user. Before the second instruction data packet is encapsulated, the sequence number value needs to be extracted from the user instruction, and then the number of information instruction data blocks contained in the analyzed user instruction is judged. And if the analyzed user instruction only contains one information instruction data block, adding the extracted sequence number value to the information instruction data block, and packaging the information instruction data block into a second instruction data packet. If the analyzed user command contains a plurality of information command data blocks, combining the plurality of information command data blocks into an information command data group, then adding the extracted sequence number value to the information command data group, and packaging the information command data group into a second command data packet. The serial number value can help a user to accurately control the smart home, and disorder of data transmission is avoided.
In one embodiment, the step of encapsulating the information instruction data block and the sequence number value into a second instruction data packet includes:
if a plurality of information instruction data packets exist, combining the information instruction data blocks to obtain an information instruction data group;
and packaging the information instruction data group 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 a data packet, and the user instruction can be sent to the corresponding internet of things terminal through the network.
In the user instruction, the same user instruction contains one or more different information instruction data packets, and each information instruction data packet can be analyzed to obtain one information instruction data block, so that the analyzed user instruction contains one or more information instruction data blocks. If the analyzed user command only contains one information command data block, the information command data block can be packaged into a second command data packet after a serial number value is added to the information command data block. If the analyzed user command contains a plurality of information command data blocks, the data blocks jointly form the user command, so that the plurality of information command data blocks need to be combined into an information command data group, and then the information command data group is added with a serial number value and packaged into a second command data packet. The second instruction data packet is set by a technical person in the field according to a preset rule, and is used for transmitting a user instruction sent by a user from the multimedia communication platform to the internet of things terminal 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 group includes:
copying each information instruction data block according to preset copying times to obtain copied data blocks;
setting the information instruction data block and a copy data block corresponding to the information instruction data block as a target data block; and determining the information instruction data group according to the target data block.
In this embodiment, in order to obtain a plurality of identical second instruction data packets, after the information instruction data packet is analyzed to obtain an information instruction data block, the information instruction data block needs to be copied according to a preset number of copies to obtain a copied data block identical to the information instruction data block, then the identical information instruction data block and copied data block are set as target data blocks, and an information instruction data group is determined according to the target data blocks.
In the user instruction, the same user instruction contains one or more different information instruction data packets, and each information instruction data packet can be analyzed to obtain one information instruction data block, so that the analyzed user instruction contains one or more information instruction data blocks. In some embodiments, if the user command includes only one information command data block, the user command data block is copied to obtain one or more copied data blocks identical to the user command data block, and the information command data block and the copied data blocks are set as target data blocks, where each target data block can be encapsulated into a second command packet. In other embodiments, the user instruction includes a plurality of different information instruction data blocks, and each information instruction data block is copied the same number of times, so that each information instruction data block obtains one or more corresponding copied data blocks, each completely same information instruction data block and copied data block are set as a group of target data blocks, and the number of the second instruction data packets obtained by encapsulation is the same as the number of each group of target data blocks. The preset copying times are set in advance according to actual rules by technicians in the field and can be adjusted at any time according to specific conditions.
According to the scheme, the information instruction data blocks are copied, one group or a plurality of groups of multiple completely consistent 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 set of information instruction data 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 group.
In this embodiment, if only one information instruction data packet exists in the user instruction, the target data block does not need to be combined; if a plurality of information instruction data packets exist, after the information instruction data blocks are copied, the target data blocks need to be recombined. Because the target data block corresponding to the same information instruction data packet is one, the information instruction data blocks are multiple, and the combination steps are as follows: one of each kind of target data block is extracted and combined to obtain an information instruction data group. Thereafter, the specific steps of the combination are repeated until all the target data blocks are combined into the information instruction data group. The process of converting the information instruction packet into the second instruction packet may take various forms, one of which is described below.
In an embodiment, as shown in fig. 3, the user instruction includes two information instruction data packets, which are named as Frame1 And Frame2, And the flag type of the DTMF stream in Frame1 is first parsed to obtain a flag type of 106, then the audio RTP stream in Frame1 is decoded, the sub packet with the flag type of 106 is extracted, then the extracted sub packet is parsed according to the RFC2833 protocol, And an Event ID value And an End of Event identification bit are extracted to obtain a DTMF value, And then the obtained DTMF value is encoded according to the And-SIP protocol to obtain a Bitstream1 data block. And (5) obtaining the Bitstream2 data block by the Frame2 data packet according to the analysis mode of the Frame1 data packet. The preset number of times of copying in this embodiment is 1. Thus, the Bitstream1 data block is copied into a Bitstream1+ data block, and the Bitstream2 data block is copied into a Bitstream2+ data block, where the Bitstream1 data block and the Bitstream1+ data block are a set of target data blocks corresponding to the Frame1 data Packet, and the Bitstream2 data block and the Bitstream2+ data block are another set of data blocks corresponding to the Frame2 data Packet, and then the Bitstream1 data block is combined with the Bitstream2 data block, and then the sequence number value corresponding to the user command is added and packed to obtain a second command data Packet, which is named Packet1, and the Bitstream1+ data block is combined with the Bitstream2+ data block, and then the sequence number value corresponding to the user command is added and then the sequence number value corresponding to the user command Packet is packed to obtain a second command Packet pad 2. The Packet1 and the Packet2 contain the same user command, so that even if the Packet1 is lost in the process of being sent to the terminal, the terminal can still obtain the user command through the Packet 2.
By means of copying the original information instruction data block and recombining the original information instruction data block into a plurality of same instruction data packets, guarantee can be added to the transmission of the user instruction, and the data loss in the user instruction transmission process is reduced.
