The following will explain the control method of the intelligent home appliance provided by the present invention with reference to the structural composition of fig. 4:
fig. 5 shows a flowchart of a control method of an intelligent home appliance according to an embodiment of the present invention. The method is implemented based on the above blockchain system, and is specifically executed by the blockchain management device, and in this embodiment, the method is mainly described in a remote control manner.
As shown in fig. 5, the method comprises the steps of:
step S510: and receiving a first general instruction sent by the block chain application software, and converting the first general instruction into a first device native instruction.
Specifically, the native and generic instruction translation sub-module in the instruction translation module 210 in the blockchain management device translates the first generic instruction into a first device native instruction that can be used to control the target smart appliance.
Wherein the first general instruction is obtained by: and the user initiates a control operation activity, namely a first control operation, to the target intelligent household appliance through a network end operation interface (namely an interface displayed on the control terminal by the network end application module) of the blockchain application software. This action may be instantiated as a user controlling the state of a smart appliance through a blockchain APP (i.e., blockchain application software) on a control terminal (e.g., smart phone), such as remotely turning on a water heater through the phone APP. The network end application module in the block chain APP analyzes the first control operation into a first general instruction, the general instruction is designed for adapting to unique original instructions of different manufacturers, and developers of different intelligent household appliance manufacturers can establish corresponding relations from the original instructions to the general instructions through an instruction compiling tool. The blockchain APP may then send the first generic instruction to the blockchain management device of the target smart appliance over the network.
In addition, after the network end application module of the blockchain APP of the control terminal analyzes the first general instruction, the blockchain management module in the blockchain APP also records the general instruction string of the first general instruction into the blockchain storage area as the latest instruction record through the blockchain access control module, namely, the current block is counted; when a new record appears in the blockchain, a blockchain management module in the blockchain APP changes the record to the global synchronization, and the record is added at the same time as long as the record is registered to all intelligent household appliances in the same blockchain domain where the control terminal is positioned and nodes of the control terminal; if a plurality of new records appear at the same time, a common recognition mechanism is realized by adopting a time stamp comparison mode, the time is counted in advance and the time is counted in sequence, and finally a stable block is formed.
Step S520: judging whether the record corresponding to the first general instruction in the instruction record synchronized through the whole domain in the intelligent household appliance is legal or not; if yes, go to step S530; if not, step S550 is performed.
After the primary and general instruction conversion module obtains the primary instruction of the first device through conversion, the primary and general instruction conversion module sends the primary instruction and the primary instruction of the first device to the device management module 230 through the instruction interaction interface, and specifically sends the primary instruction and the primary instruction of the first device to the instruction management module in the device management module 230, the instruction management module judges the validity of the primary instruction in the synchronous record in the node corresponding to the intelligent household appliance through the Hash value of the Merkle root node, namely judges whether the primary instruction exists in the block, if yes, the primary instruction is legal, if not, the primary instruction of the first device is illegal, and then executes the primary instruction of the first device according to the judging result.
Step S530: the first device native instructions are executed.
If the first device native instruction is judged to be legal, further judging whether the first device native instruction is to be executed immediately; if the first device native instruction is to be executed immediately, executing the first device native instruction immediately; if not, the first device native instruction is executed when the set execution time is reached.
Specifically, the instruction management module judges whether the first equipment native instruction is immediately executed, if yes, the instruction management module immediately executes the first equipment native instruction through the equipment self-control module, if not, the instruction management module sets the execution time, and when the execution time is reached, the first equipment native instruction is executed through the equipment self-control module.
Step S540: after the execution is finished, the operation success information is fed back to the blockchain application software, so that the blockchain application software can display the notification of the operation success to the user.
After the device self-control module executes the first device native instruction, the device self-control module feeds back operation success information to the blockchain APP of the control terminal, and then the blockchain APP displays a notification of operation success to a user through a terminal operation interface. For example, it is shown that the water heater has been successfully powered on according to the user's operation on the cell phone.
Step S550: refusing to execute the first device native instruction and feeding back operation failure information to the blockchain application software.
If the remote control is illegal, feeding back operation failure information to the blockchain APP, and prompting the user of the remote control failure through a terminal operation interface.
According to the control method of the intelligent household appliance, point-to-point remote control of the intelligent household appliance can be achieved through the blockchain APP in the control terminal, validity verification can be conveniently conducted through global synchronization, and illegal remote control is avoided.
Fig. 6 shows a flowchart of a control method of an intelligent home appliance according to another embodiment of the present invention. The difference between this embodiment and the embodiment corresponding to fig. 5 is that this embodiment is mainly described in a manner of directly controlling the proximity of the smart home appliance.
As shown in fig. 6, the method comprises the steps of:
step S610: and receiving a second control operation initiated by the user for performing touch control on the intelligent household appliance, and analyzing the second control operation into a second equipment original instruction.
The user triggers the second control operation through a panel-end operation interface on the smart home (formed by a panel-end application module in the device management module 230), which may be exemplified by the user controlling the state of the smart home through a button panel on the smart home, such as pressing a power button on the water heater to turn on the power. The instruction management module in the device management module 230 then parses the second control operation into second device native instructions,
step S620: the second device native instructions are converted into second general purpose instructions.
The instruction management module in the device management module 230 sends the parsed second device native instruction to the native and general instruction conversion module in the instruction conversion module 220 through the instruction interaction interface, and the native and general instruction conversion module converts the second device native instruction into a second general instruction.
Step S630: the second general purpose instruction is counted as the latest record in the block and the latest record is synchronized to all nodes of the associated blockchain domain.
The blockchain management module in the blockchain module 210 records the second general instruction as the latest instruction record into the blockchain storage area, namely the current block, through the blockchain access control module; when new records appear in the blockchain, the blockchain management module synchronizes the record change to the universe, so that the record is added to each node in the blockchain system at the same time, and correspondingly, the record is added to the node corresponding to the intelligent household appliance, thereby facilitating subsequent validity verification.
Step S640: judging whether the record corresponding to the second general instruction in the instruction record synchronized through the whole domain in the intelligent household appliance is legal or not; if yes, go to step S650; if not, step S670 is performed.
After the primary and general instruction conversion module obtains the second general instruction through conversion, the second general instruction and the primary instruction of the second device are transmitted back to the instruction management module of the device management module 230, the instruction management module judges the validity of the second general instruction in the synchronous record in the node corresponding to the intelligent household appliance through the Hash value of the Merkle root node, namely, judges whether the second general instruction exists in the block, if yes, the second general instruction is legal, if not, the second general instruction is illegal, and then the primary instruction of the second device is executed according to the judging result.
Step S650: and executing the second device native instructions.
If the first device native instruction is judged to be legal, further judging whether the first device native instruction is to be executed immediately; if the first device native instruction is to be executed immediately, executing the second device native instruction immediately; if not, the second device native instruction is executed when the set execution time is reached.
Specifically, the instruction management module judges whether the second equipment native instruction is immediately executed, if yes, the instruction management module immediately executes the second equipment native instruction through the equipment self-control module, if not, the instruction management module sets the execution time, and when the execution time is reached, the second equipment native instruction is executed through the equipment self-control module.
Step S660: after the execution is finished, the operation success information is fed back to the front-end panel of the intelligent household appliance.
After the device automatic control module executes the primary instructions of the second device, the device automatic control module feeds back the successful operation information to the front panel (formed by the panel end application module) of the intelligent household appliance, so that the user can be prompted that the second control operation is successful.
Step S670: refusing to execute the primary instruction of the second equipment and feeding back operation failure information to the front-end panel of the intelligent household appliance.
If the operation failure information is judged to be illegal, the operation failure information is fed back, and the user is prompted to fail the short-range operation through the front-end panel.
According to the control method of the intelligent household appliance, the second control operation can be triggered through the front panel of the intelligent household appliance, and the validity check of the second general instruction can be conveniently carried out before the second equipment original instruction corresponding to the second control operation is responded through global synchronization, so that illegal short-range control is avoided.
