detailed description

In the technical solution provided by this application, the implementation of the locking method relies on the gas stove and user terminal equipment, and the gas stove needs to be added with a corresponding controller on the basis of the traditional gas stove to execute the corresponding locking and unlocking procedures . Refer to Fig. 2, which is a schematic flowchart of a method for locking a gas stove according to this application. In order to prevent gas leakage or fire caused by children's misoperation, as shown in Figure 2, the gas stove locking method provided in this application includes the following steps:

S1: Get the current system time every preset time interval.

In this application, the preset time interval is the update interval of the unlocking sequence of the gas stove. The specific time can be set by itself according to the complexity of the control components on the gas stove and actual application requirements. For example, when there are many control components and/or many control components, that is, when the degree of freedom of operation is high, since the gas stove is less likely to be unlocked by a child's operation, the preset time interval can be set to be longer. For example, the preset time interval is set to 1h to reduce the computing load of the controller. For another example, there are fewer control components on a gas stove, and fewer control components have fewer operating positions, that is, when the degree of freedom of operation is low, since the gas stove is more likely to be unlocked by children's misoperation, the preset time interval can be set to be shorter; For example, the preset time interval is set to 1 min, so as to reduce the possibility of children operating multiple times to unlock the gas stove.

In the technical solution provided by this application, the judgment of the preset time can be realized by a timer built into the controller, which is timed at the beginning of the trigger system control; it can also be realized by synchronizing the standard time to calculate whether the preset time is reached interval. In practical applications, in order to facilitate keeping the timing rules of the gas stove controller and the smart terminal device consistent, the implementation of synchronized standard time may be preferred.

Further, as shown in Fig. 3, the steps of obtaining the current system time every preset time interval include:

S11: Detect whether the control terminal is within the coverage of the home network where the gas stove is located;

S12: If the control terminal is within the coverage area of the home network, receive a lock instruction sent by the control terminal;

S13: After receiving the lock instruction, execute the step of obtaining the current system time every preset time interval;

S14: If the control terminal is not within the coverage of the home network, obtain the current system time every preset time interval.

It can be seen from the above steps that the corresponding locking procedure can be automatically triggered by detecting whether the control terminal is in the home network. In this embodiment, it can first detect whether the control terminal is within the coverage of the home network where the gas stove is located, that is, whether the control terminal is connected to the same gateway device as the gas stove. If it is detected that the control terminal has been connected to the gateway device, it is determined that the control terminal is not within the coverage of the home network, and then it is determined that the owner of the control terminal (the child’s guardian) has left the house, the corresponding lock procedure can be activated to avoid children Misoperation.

In addition, after detecting that the control terminal device is disconnected from the gateway device in the home, the control instruction and prompt information for locking the gas stove can be sent to the control terminal through the Internet. For example: "It is detected that you have gone out, do you want to lock the gas stove?" The user can choose whether to lock the gas stove through the control command, that is, send a lock instruction to the gas stove. At this time, the gas stove needs to receive the lock instruction sent by the control terminal, and after receiving the lock instruction, execute the step of obtaining the current system time (S1) at preset time intervals. In this embodiment, the user can lock the gas stove purposefully through the lock instruction, so as to avoid frequent replacement of the lock sequence and inconvenience to the normal use of the gas stove.

In the embodiment of the present application, after the user leaves the coverage of the home network, the user can determine whether to send a lock instruction according to his actual situation, that is, whether to lock the gas stove. For example, there are no children in the user's home, or other guardians are present to accompany the user when he leaves the home. In these cases, the gas stove may not be locked to avoid the trouble of unlocking the gas stove when the gas stove is subsequently used.

In this embodiment, if the control terminal is within the coverage of the home network, the lock instruction sent by the control terminal is received, that is, it is determined that there is a guardian in the family at the current time. Although it can be supervised by humans to avoid misoperation by children, it can also be controlled by the control terminal. Lock the gas stove to avoid negligence.

Further, in this embodiment, detecting whether the child is under the supervision of a guardian is realized by detecting whether the current control terminal is connected to the gateway device, as shown in FIG. 4, the specific detection method may include the following steps:

S111: Obtain current access device information in the corresponding gateway device of the home network;

S112: Extract the device identification code corresponding to each device in the current access device information;

S113: Match the device identification code with a preset terminal list, where the preset terminal list includes identification codes corresponding to multiple control terminals;

S114: If the current access device information includes the control terminal identification code in the preset terminal list, determine that the control terminal is within the coverage of the home network.

In this embodiment, the lock control program of the gas stove is built into the controller. When step S11 is implemented, the information of all currently connected devices can be obtained through the gateway device. The specific information can be the ID or MAC code of each linked device , The extracted information must be able to uniquely represent the control terminal. After obtaining the current access device information, the corresponding device identification code can be extracted, and then the identification code is used to match the preset terminal list. The preset terminal list may be a pre-stored list, in which the information of each terminal device that determines the owner as a guardian is recorded, for example, the child's parents.

Finally, if the current access device information includes the control terminal identification code in the preset terminal list, and it is determined that the control terminal is within the coverage of the home network, then continue to perform step S12. If the current access device information does not include the control terminal identification code in the preset terminal list, it is determined that the control terminal is not within the coverage of the home network, and step S14 is directly executed.

Further, as shown in FIG. 5, if the control terminal is not within the coverage of the home network, the method further includes:

S141: Record the departure moment when the control terminal leaves the coverage area of the home network;

S142: From the moment of departure, detect whether the control terminal enters the coverage area of the home network again;

S143: If the control terminal does not re-enter the coverage area of the home network within the preset time period after the departure time, execute the step of acquiring the current system time every preset time interval.

That is, in practical applications, if the guardian only temporarily leaves the coverage of the home network, the locking procedure may not be activated temporarily to avoid the inconvenience of re-unlocking when the user operates again.

S2: Generate an unlocking sequence in the current time period according to the current system time, where the unlocking sequence includes a combination of operation states of multiple control components on the gas stove.

In the technical solution provided by this application, an unlocking sequence in the current time period is generated according to the current system time, that is, in each preset time interval, there is a corresponding unlocking sequence. As time goes by, new time periods are continuously entered, and each new time period is entered, corresponding to a new unlock sequence. Therefore, when in the locked state, the unlocking sequence is continuously updated in real time, thereby reducing the possibility of children's misoperation to unlock the gas stove.

Specifically, the step of generating an unlocking sequence in the current time period according to the current system time further includes the following steps:

S21: Generate a locked characteristic value according to the current system time, and save the locked characteristic value, where the locked characteristic value includes a numerical sequence combined according to a preset rule;

S22: According to the locked characteristic value, determine in a preset characteristic combination table the operating state combinations of the multiple control components corresponding to the locked characteristic value.

In this embodiment, the locked characteristic value may be generated according to the preset time conversion rule and the current system time, and the locked characteristic may be a numerical sequence combined according to a predetermined rule. The actual locked characteristic value can be set according to the complexity of the conversion rule. For example, the actual conversion rule may include extracting the values of year, month, day, hour, and minute in the current system time, and determining the corresponding characteristic value according to the parity of the value. For example, if the current system time is 18:20 on January 1, 2019, the corresponding feature value can be: 00011 (where 0 represents an odd number and 1 represents an even number). After the corresponding feature value is obtained, the preset operating state combination can be further queried in the feature combination table according to the feature value.

For another example, there are 5 buttons for locking on a gas stove, where the pressed state is 1 and the unpressed state is 0. In the actual unlocking process, the unlocking state sequence corresponding to the characteristic value 00011 is "unpressed, Not pressed, not pressed, pressed, pressed". You can also choose a more complicated operation method, for example, through a 5×5 combination sequence table, all the combinations of the values on each bit in the feature value correspond to a specific combination sequence. Obviously, the above embodiments only show a simple direct correspondence relationship. In practical applications, more complicated conversion methods can also be set to further reduce the possibility of children's misoperation of unlocking.

Further, as shown in FIG. 6, the step of generating a locked characteristic value according to the current system time further includes:

S211: Extract the current date and the current time in the current system time;

S212: A first characteristic value generated according to the current date, and a second characteristic value generated according to the current moment;

S213: According to the combination of the first characteristic value and the second characteristic value, determine the operation state combination of the multiple control components in the preset characteristic combination table.

In this embodiment, the unlocking mode can be further set according to the number of operating components on the gas stove. For example, when there are only two operating components on the gas stove, one of them may correspond to the first characteristic value, and the other may correspond to the second characteristic value. Therefore, the first characteristic value is generated according to the current date information, and the second characteristic value is generated according to the time information, and then the final operation state combination is determined. For example, the two operating components on the gas stove can be rotated to be in different gears. The current system time is 18:20 on January 1, 2019. It is divided by season and time period. The corresponding date is January 1 The first gear, that is, the characteristic value is 1, 18:20 is the third gear, and the characteristic value is 3. During this time period, the first operating part needs to be rotated to the first gear, and the second operating part is rotated to The second gear can be unlocked.

S3: Detect the operation state of each control component on the gas stove, and generate an operation sequence.

In this embodiment, after the unlocking sequence in the current time period is generated according to the current system time, the controller of the gas stove can detect the operating state of the control component in real time during application. When the operating state changes, the final operating state Perform detection and finally generate sequence of operations.

According to different types of actual control components, the operation sequence in this application can include multiple forms. For example, in the foregoing example, a control component composed of 5 buttons can correspond to a 5-digit field, and each digit can have Two specific values, namely 0 if not pressed, and 1 if pressed. Correspondingly, in practical applications, users can press buttons to perform operations when they need to use a gas stove. If the operation sequence pressed by the user is "not pressed, not pressed, not pressed, pressed, pressed", the corresponding generated operation sequence is 00011.

For other types of control components, such as knobs, the angle that can be rotated is divided into multiple gears, that is, 0-90 degrees is the first gear, 90-180 degrees is the second gear, and 180-270 degrees is The third gear, 270-360 is the fourth gear. Corresponds to a 2-digit field, where the first digit represents the value corresponding to the gear of one knob, and the second digit represents the value corresponding to the gear of the other knob. For example, if the first knob is rotated 60 degrees, and the second knob is rotated 280 degrees, the generated operation sequence is 13.

S4: Compare the operation sequence with the unlock sequence.

After the operation sequence is generated, the generated operation sequence can be compared with the unlock sequence to determine whether the operation sequence is consistent with the unlock sequence.

Further, as shown in FIG. 7, the step of comparing the operation sequence with the unlocking sequence further includes:

S41: Generate an unlocking characteristic value according to the operation sequence;

S42: Extract the stored locked feature value;

S43: Compare whether the unlocking characteristic value is consistent with the locking characteristic value.

In this embodiment, the unlock feature value can also be generated according to the operation mode of the control component. The method of generating the unlock feature value is the same as that of the lock feature value in the foregoing embodiment. By comparing the unlock feature value and the lock feature value, data comparison can be reduced. Increase the contrast speed of the controller.

S5: If the operation sequence is consistent with the unlocking sequence, open the lock control valve provided on the gas pipeline.

In this application, if the unlocking sequence in the current time period is 00011, and the corresponding operation sequence generated by the control component is also 00011, it is determined that the operation sequence is consistent with the unlocking sequence, and it is determined that the user of the current gas stove can correctly operate the gas stove. Therefore, the opening command can be generated by the controller to open the lock control valve on the gas pipeline, so that the gas stove can supply gas normally and realize its function.

S6: If the operation sequence is inconsistent with the unlocking sequence, send an unlocking notification to the control terminal, and after receiving an unlocking instruction from the control terminal for the unlocking notification, open the lock control valve.

In practical applications, the complexity of the operation of the gas stove will bring users troubles in use. Therefore, in order to enable the operator to unlock quickly, in actual applications, if the operation sequence is inconsistent with the unlocking sequence, an unlocking notification can be sent to the control terminal through the gateway device and the Internet. The user of the control terminal can determine whether the operation is reasonable according to the actual situation, and when it is determined that the user of the current gas stove is not a child, send an unlocking instruction to the controller. After the controller receives the unlock command, it skips the comparison program and opens the lock control valve.

It can be seen that in the technical solution provided by the present application, the gas stove can be locked when not in use through the control component on the gas stove. By comparing the operation sequence and the unlocking sequence, it can be determined whether the user of the current gas stove can correctly use the gas stove, thereby increasing the unlocking method of the gas stove and avoiding the situation that cooking cannot be performed in individual cases. In addition, according to the current system time, the unlocking instruction updated in real time can reduce the possibility of children unlocking the gas stove by mistake.

In addition, the control terminal 2 can be connected to the gateway device 3 through a WLAN network, and the gateway device 3 is connected to the Internet to realize data transmission.

In practical applications, the gas stove 1 has complete traditional stove functions, that is, a combustion head, a gas supply pipeline, an ignition device, an adjustment device, and so on. However, as a gas stove that can be locked, a plurality of control components 11 are provided on it, and each of the control components 11 has a plurality of adjustable operating states; the gas stove 1 also includes a locking control provided on the gas pipeline The valve 12 is provided with a controller 13 in the gas stove, and both the control component 11 and the locking control valve 12 are connected to the controller 13. The controller 13 may also establish a communication connection with the gateway device 3 through a WLAN network, so that corresponding control instructions can be sent to the control terminal 2 through the gateway device 3 and the Internet. The controller 13 is further configured to execute the following program steps:
