Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and examples.
NFC is a near field communication technology, in which data exchange can be performed between devices (e.g., mobile terminals) using the NFC technology or between devices and electronic tags using NFC for reading and writing under the condition of being close to each other, and is integrated and evolved from a non-contact Radio Frequency Identification (RFID) and an interconnection technology, and functions of an induction card reader, an induction card and point-to-point communication are integrated on a single chip. Based on a series of problems existing in the control mode of the existing household appliance, the invention provides a household appliance control method, which realizes simple and convenient control of the household appliance by means of an NFC (near field communication) identification technology, and has a convenient and reliable control effect. The following description will be made in detail with reference to a specific embodiment.
Example one
The present embodiment provides a method for controlling a home appliance, as shown in fig. 1, including the following steps:
the mobile terminal reads information in the NFC label;
and the mobile terminal judges the consistency of the identity information of the household appliance to be controlled in the NFC label and the locally stored identity information of the household appliance to be controlled, and when the identity information is consistent, the mobile terminal acquires control information according to the read information in the NFC label and sends the control information to the household appliance to be controlled.
The mobile terminal can be an intelligent terminal such as a mobile phone, an intelligent bracelet, an intelligent watch and a tablet computer which are commonly used at present, and can also be terminal equipment with network communication functions in other forms, and the mobile terminal has an NFC reading function.
Through reading the information in the NFC label by mobile terminal in this scheme, rather than directly reading by household electrical appliances, make full use of present mobile terminal's NFC function on the one hand, need not to set up the NFC in addition for household electrical appliances and read the function to the manufacturing cost of control household electrical appliances improves product competitiveness. On the other hand, because the functions and types of the household appliances are different, such as a wall-mounted air conditioner, an electric water heater, a gas water heater and the like, and are limited by the assembly positions or the assembly heights of the household appliances, a user is not easy to operate the household appliances in a short distance, the user is further convenient to operate, meanwhile, the advantage that the current mobile terminal becomes an essential necessity in daily life of people is fully utilized, the user can obtain the control information only by simply operating a mobile phone, and the control information is issued to the household appliances through a network to execute control. The operation is very convenient.
And after receiving the control information, the household appliance executes corresponding operation according to the control command carried in the control information.
For a user, according to the reading principle of NFC, only the mobile terminal and the NFC tag need to be placed in the radio frequency identification area (the mobile terminal and the NFC tag may or may not be in contact with each other), and automatic reading of information and automatic issuing of control information can be achieved. The user does not need to call application software of the household appliance in the mobile terminal, and then gradually sets and other operations according to the prompt, so that the operation program is greatly simplified, and the method is particularly suitable for operation control of old people and special people (such as people with visual impairment).
Before the mobile terminal reads the information in the NFC label, the method also comprises the step of configuring the mobile terminal and the NFC label, wherein at least the identity information of the household appliance to be controlled is stored in the mobile terminal. The identity information of the household appliance is the unique identification number of the household appliance.
The NFC label stores identity information of the household appliance to be controlled and also stores control information or codes of the control information.
When the NFC label stores control information, the control information can be directly acquired after the mobile terminal reads the information in the NFC label, and the control information can be sent to a household appliance execution command after the identity information of the household appliance to be controlled in the NFC label is judged to be consistent with the locally stored identity information of the household appliance to be controlled.
Preferably, in this embodiment, the mobile terminal sends the information to the household appliance through the server, that is, when the NFC tag stores the control information, the mobile terminal obtains the control information by reading the NFC tag, and sends the control information and the identity information of the household appliance to be controlled to the server, and the server sends the control information and the identity information of the household appliance to be controlled to the household appliance to be controlled through the network.
When the code of the control information is stored in the NFC label, the mobile terminal locally acquires the control information corresponding to the code according to the code, after the mobile terminal reads the code in the NFC label, the control information corresponding to the code is searched locally according to the code, and then the control information is sent to the household appliance.
Or the control information corresponding to the code is stored in the server, the mobile terminal sends the code to the server after acquiring the code, the server acquires the control information corresponding to the code, and the server sends the control information to the household appliance to be controlled according to the identity information of the household appliance to be controlled.
In order to prevent the household appliance from being unable to be normally controlled due to the error of writing information in the NFC tag or the error of reading by the mobile terminal, the method preferably further includes the step of matching the control information with a pre-stored command after the control information in the NFC tag is read by the mobile terminal, and when the matching is successful, the control information and the identity information of the household appliance to be controlled are sent to the server. To ensure that the home appliance can normally execute the control information.
The mobile terminal judges the consistency of the identity information of the household appliance to be controlled in the NFC label and the locally stored identity information of the household appliance to be controlled, and the consistency is used for preventing the household appliance from being controlled normally due to the fact that a user takes the NFC label by mistake.
When the identity information of the household appliance to be controlled in the NFC label is inconsistent with the identity information of the household appliance to be controlled of the mobile terminal or when the control information is not successfully matched with the prestored command, the mobile terminal gives an alarm to prompt an error, so that a user can check and confirm in time and use delay is prevented.
After the mobile terminal acquires the control information, the step of displaying the control information on the mobile terminal is further included, the modifiable input is supported by the control parameter display frame, after a user holds the mobile terminal to read the NFC tag, the control information in the NFC tag is displayed and output through a display screen of the mobile terminal, the user can check whether the control information is consistent with the operation control to be executed by the user, and when the control information is inconsistent, the user can modify the control information through the mobile terminal.
The mode supporting modification is a remedy measure for a user to take an NFC label by mistake, or the existing NFC label does not have control operation which is currently required to be executed by the user, a rapid modification way can be provided for the user, the user does not need to start household appliance control application software in the mobile terminal, the control operation which is required to be executed is searched from the application software, the mobile terminal can pop up the control information recorded in the NFC label only by taking the mobile terminal to be in close contact with the NFC label, and the user determines whether to modify or not to modify the NFC label.
If the user modifies the control information, the mobile terminal records the modified information and sends the modified control information to the server.
In order to prevent the situation that the user does not pay attention to subsequent operations after reading the NFC information, so that the control information cannot be sent and the use of the user is delayed, the mobile terminal displays the control information, then performs timing, and if the user does not perform modification operation within set time, sends the control information to the server. Therefore, the time for modifying the control information can be reserved for the user, and the control information can be timely sent to the household appliance for execution when the user does not modify the control information, so that the user is not delayed in using the electric appliance.
Because the information written in the NFC label has the customized function, the information can be used for recording the favorite control information of different family members to the household appliance, the control information of different family members is not necessarily the same, a plurality of NFC labels are generally needed, and the information recorded in each NFC label is different, so that the preferred user can write the information into the NFC label according to the actual requirement of the user.
Specifically, the present embodiment further includes a step of writing information to the NFC tag, including:
selecting information to be written in the mobile terminal;
the mobile terminal searches for an NFC tag in a communicable range of the mobile terminal and sends a wake-up command to the NFC tag;
reading address information of the NFC label, and performing key verification;
and after the verification is passed, the information to be written is sent to the NFC label and stored in the corresponding storage area.
The NFC tag readable and writable principle is as follows: as shown in fig. 2, the NFC tag has several storage sectors, where the 0 th sector is used to store address information of the NFC tag and information written by a manufacturer, and generally does not need to be analyzed and modified; block 0, block 1, block 2 of each sector are data blocks that may be used to store data; the block 3-bit control block consists of a password A, an access control (control word) and a password B, and the password and the access control of each sector are independent, namely each sector has its own password.
When a user starts to read information to the NFC tag, a wake-up command is sent, and then address information of the tag is read. And then, key verification is carried out, card reading operation is started after the verification is finished, and reading operation is carried out according to the information input of the block 3 during card reading. The write operation is essentially the same step as the read operation except that the write operation is adjusted for read control at block 3.
When the mobile terminal of the user opens the NFC function and performs the collision operation with the NFC, the mobile terminal is in a passive mode in the NFC near field communication protocol. The mobile terminal acts as a master device generating a radio frequency field and sending a signal to a slave device (NFC tag). The slave device does not generate a radio frequency field, so that a power supply device is not needed, the radio frequency field generated by the master device is converted into electric energy, the circuits of the slave device are powered, data sent by the master device are received, and the data of the slave device are transmitted back to the master device at the same speed by using a load modulation technology. The mobile terminal reads and writes the NFC label in a passive mode.
The information communicated between the NFC tag and the mobile terminal follows a preset protocol, and the simple introduction of the protocol is shown in the table 1:
| frame header | Frame length | Reservation | Frame type | Data information | Checksum |
| FFFF | 8+n | FFFF FFFF | 00 | Reservation information | FF |
TABLE 1
The frame header is a start mark of information, the frame length indicates the length of frame data, the reservation is used as supplementary information of a protocol, the type of the frame indicates the difference of data (control information, setting information, state information and the like), and the data information expresses the data information (specific control information, setting information, state information) of a function. The checksum is the sum of byte-wise addition of the frame length and the frame body valid information, and takes the low byte of the sum, and the sum includes redundant data during transmission.
The communication process when the information is stored in the NFC label is that the mobile terminal performs reading operation by touching the NFC label, and the mobile terminal and the NFC label are in passive mode communication and follow a preset protocol. The mobile terminal reads information in the NFC label to open the smart APP, and the APP analyzes the information in the NFC label according to a protocol. Then APP will issue the read information WIFI to the water heater, and the single chip of the water heater analyzes the received command to execute corresponding operation. When the mobile terminal carries out information burning, the APP interface has a corresponding operation interface, and a user can combine the functions required by the user in a user-defined mode in the operation interface. After the user chooses to complete the function he wants, the APP will combine the information according to the protocol. After the user selects the burning key, the mobile terminal is only required to be close to the NFC label, so that the information set by the user is transmitted to the NFC label, and meanwhile, the APP can feed back a mark indicating that information burning is finished. Therefore, when the user uses the mobile terminal again to touch the NFC label, the preset function can be realized, and the idea of the user can be quickly and conveniently realized, so that the redundant operation is avoided.
NFC is only the communication logic of storage identity information, for example, the NFC card has only stored such a code of 001, can be at the information that this serial number corresponds of high in the clouds analysis when mobile terminal reads this code, then issues the water heater to corresponding information through WIFI. The writing operation also enables a user to combine functions which the user wants, and the combination corresponds to a sequence code which is determined to be realized. When the mobile terminal writes data through collision, the NFC tag stores the sequence code of the corresponding information.
Example two
The invention also provides a water heater, which receives the control information and executes the corresponding control command, wherein the control information acquisition method comprises the following steps:
the mobile terminal reads information in the NFC label;
and the mobile terminal judges the consistency of the identity information of the water heater in the NFC label and the identity information of the water heater stored locally, and when the identity information of the water heater in the NFC label is consistent with the identity information of the water heater stored locally, the mobile terminal acquires control information according to the read information in the NFC label and sends the control information to the water heater.
Taking a water heater as an example, the control information for controlling the water heater may include power on/off, set temperature, bacteriostasis, heat preservation, and the like.
For other contents of the control method of the water heater in this embodiment, reference may be made to the household appliance control method described in the first embodiment, which is not described herein again.
EXAMPLE III
The NFC tag records the startup control information, and a user can realize the function of startup by touching the mobile terminal with the NFC tag in a close range. The user does not need to perform any other operation. When the user wants to execute the shutdown, the mobile terminal is in close-range contact with the NFC label written with the shutdown control information, so that the 'one touch shutdown' is realized, and the shutdown method is very convenient.
In addition, the user can also contact the mobile terminal with the NFC chip recorded with the heating temperature in a close range, and the 'one touch set heating temperature' is realized.
Example four
The NFC label is configured into the modularized label in the embodiment, a user can closely contact the mobile terminal with the NFC label, an interface with the same content as that of a control panel of the water heater can be displayed in a display screen of the mobile terminal, the user can operate and set the NFC label, a double-screen control interface is actually provided for the water heater, and the problem that the user inconveniently operates the control panel on the water heater due to the fact that the water heater is installed too high is solved.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
