The embodiment of the invention discloses a control method and a control system for time-limited flameout and a stove, which can automatically start timing when the stove is used, close a valve to flameout after timing time is reached, and avoid the danger caused by the fact that a user needs to actively start a timing device when the stove is used or forget to start the timing device when the stove is used. The following detailed description refers to the accompanying drawings.
Example 1
Referring to fig. 1, fig. 1 is a flow chart of a control method for time-limited flameout according to an embodiment of the present invention. The method described by the embodiment of the invention is suitable for a kitchen range, an execution main body for realizing the local flameout method can be a control module in the kitchen range, or can be control equipment with a certain processing function outside, the control equipment can be in wired or wireless communication with the control module in the kitchen range, a control instruction is issued to the control module in the kitchen range, and the control module in the kitchen range executes corresponding control operations of the control equipment, such as timing, valve closing and the like. The control device can be an intelligent terminal such as a mobile phone, a tablet personal computer and the like, and can also be a cloud server, a remote controller and the like, and can be used as an execution main body of the embodiment of the invention as long as the control device can receive corresponding fire value information and perform relevant processing according to the fire value information. As shown in fig. 1, the control method for time-limited flameout includes the following steps:
110. and receiving the fire value information, and determining a valve closing time length threshold according to the fire value information. There are various ways of receiving the fire value information. The fire value information is illustratively received automatically during use or by manually adjusting the fire value during use.
The fire power value may be a preset fire power adjustment gear of different sizes. The fire power value may be a touch screen gear for adjusting the fire power, a valve gear for adjusting the fire power, etc., and exemplary, the touch screen gear for adjusting the fire power may be an exact gear, a plurality of gears are preset, each gear corresponds to one fire power, and each gear can control the fire power by controlling a preset output power or a preset gas flow. For example, 15 gear positions are preset, the output power of the power from 1 to 15 gear positions is sequentially increased or decreased, or the gas flow of the power from 1 to 15 gear positions is sequentially increased or decreased.
Of course, the fire power value is not limited to the above-mentioned fire power adjustment gear, and as another implementation, the flow rate information may be converted into fire power value information by providing a flow rate sensor in the gas channel to collect flow rate information. It can be understood that the flow and the firepower are in a certain corresponding relation, the corresponding relation can be determined in a multiple test mode, training and testing can be performed through machine learning, for example, a neural network model, and then flow information is input into the trained neural network model, so that the firepower value can be obtained.
In some scenarios, the fire value information may also be determined by flame temperature. The flame generates special signals such as heat, radiant light, ions and the like during combustion, and the flame temperature is obtained through detection of the special signals. Illustratively, a flame detector such as a thermocouple, infrared, or the like may be employed. Similar to the flow information, the flame temperature also has a certain corresponding relation with the fire power, and the purpose of determining the fire power value is achieved by acquiring the corresponding relation. There are various ways to determine the valve closing time period threshold based on the fire value information. For example, the valve closing duration threshold may be determined by thermal value information and preset rules.
The preset rule may be a relation function or a relation table, etc. to which the fire value information is matched.
By way of example, the preset rule may be a linear relationship function to which the fire value information matches, such as a linear relationship function of y=k/x+n (y is a valve-closing duration threshold, x is fire value information, k is a coefficient, n is a constant), k=90, n=0, and if the fire value information x=1, the valve closing duration threshold value is obtained through the linear relation function and is 90 minutes. The preset rule may also be a correlation table with which the fire value information is matched, for example, the fire value information is respectively 1 to 8, and the valve closing time threshold of the corresponding correlation table is sequentially 90 to 20 minutes, etc.
The preset rule may be, for example, a correlation table, for example, a two-dimensional table representing a relationship between the valve closing time period threshold value and the fire value, which may be obtained in a trial manner. Tables 1-4 show several two-dimensional tables:
table 1A two-dimensional Table corresponding to kitchen ranges
Table 2 corresponding two-dimensional table of B cookers
Table 3 corresponding two-dimensional table of C cookers
Table 4D two-dimensional table corresponding to kitchen ranges
In summary, by receiving the fire value information, the valve closing time length threshold is determined according to the fire value information, and the valve closing time length threshold corresponding to the fire value information is automatically matched through the change of the fire value information.
120. And starting timing, and comparing the timing time with a valve closing duration threshold.
And determining timing time according to the valve closing time threshold value, and starting timing.
The timing time can be determined in one-to-one correspondence with the valve closing time length threshold, and the timing instruction is triggered when the timing time is received, so that the timing is started. Illustratively, the valve closing duration threshold is 90 minutes, and the timing time is also 90 minutes, and the countdown is started from the timing time of 90 minutes.
And comparing the timing time with the valve closing duration threshold.
After starting timing, executing a comparison instruction, and comparing whether the timing time reaches a valve closing duration threshold.
130. And executing a valve closing instruction when the timing time reaches the valve closing duration threshold.
And after starting timing, starting countdown, and when the countdown time value is zero, ending timing, triggering and executing a valve closing instruction to control the switching off of the kitchen range or closing of the kitchen range valve, so as to achieve the aim of flameout.
For example, when the cooker is an electromagnetic cooker, the electromagnetic cooker coil ground current is disconnected, and when the cooker is a gas cooker, the gas cooker valve body is controlled to be closed, and the gas supply is disconnected, so that the gas cooker is flameout.
By implementing the embodiment of the invention, after the fire value information is determined by receiving the fire value information, the valve closing time length threshold value is obtained according to the fire value information, the timing time is determined according to the valve closing time length threshold value, the timing is started, and when the timing time reaches the valve closing time length threshold value, the valve closing instruction is executed. After the fire gear is adjusted, a user determines a valve closing time threshold value, starts timing, and automatically closes the kitchen range when the timing time reaches the valve closing threshold value, so that the danger caused by the fact that the user needs to manually open the timing flameout device or forgets to open the timing flameout device when using the kitchen range is avoided.
Example two
Referring to fig. 2, fig. 2 is a flow chart of another method for controlling a time-limited flameout according to an embodiment of the present invention. As shown in fig. 2, the control method includes the steps of:
201. and detecting ignition information.
202. And judging whether the fire is on or not.
210. And receiving the fire value information, and determining a valve closing time length threshold according to the fire value information.
220. And starting timing, and comparing the timing time with a valve closing duration threshold.
221. And detecting whether the fire value information changes.
230. Judging whether the timing time is smaller than or equal to a preset warning value.
240. Executing the prompt instruction and sending prompt information.
250. And judging whether the timing time reaches the valve closing duration threshold.
260. And executing a valve closing instruction when the timing time reaches the valve closing duration threshold.
Steps 210 and 220 and 260 in the second embodiment are substantially the same as steps 110 and 120 and 130 in the first embodiment, and will not be described here.
Before step 210, it is necessary to determine that the cooktop is already in a fire state, otherwise the following steps will lose practical significance.
And detecting ignition information. When the user starts to use, the control device triggers to generate a switch instruction to control the stove to fire, and meanwhile, fire information is detected. For example, when the kitchen range is an electromagnetic range, the electromagnetic range is controlled to be electrically connected with a power supply when a user starts a switch, current information of the electromagnetic range is detected, when the kitchen range is a gas range, when the user starts the switch, the gas range igniter is controlled to ignite and simultaneously the valve of the gas range is opened, and gas flow information of the valve body of the gas range is detected.
And judging whether the fire is on or not. After the ignition information is detected, whether the stove catches fire is judged. For example, when the stove is an electromagnetic stove, whether the electromagnetic stove catches fire is judged by a temperature sensor and an infrared sensor, and when the stove is a gas stove, whether the gas stove catches fire is judged by a light sensor, an infrared sensor and a temperature sensor.
221. And detecting whether the fire value information changes.
In the timing process, there is a case where the fire value information fluctuates, and when the fire value information fluctuates, the valve closing time period threshold value matched with the fire value information also changes. For example, when the kitchen range is an electromagnetic range, whether the fire value information changes can be judged by detecting the current of a coil of the electromagnetic range, the output power and the change of a preset fire value, and when the kitchen range is a gas range, whether the fire value is adjusted can be detected by a gas flow rate or/and gas flow sensing device arranged in the valve body. In yet another embodiment, the change of the fire value information can be detected by a rotatable potentiometer mounted on the kitchen switch knob, sensing the resistance, current and voltage changes of the potentiometer.
When the fire value information changes, the corresponding valve closing time length threshold changes, a new timing time is determined according to the changed valve closing time length threshold, and the step 210 is returned to restart timing.
For example, when the fire information value is 1 and the valve closing time length threshold corresponding to the fire information value 1 is 90 minutes when the stove is used by a user, the timing time starts counting down from 90 minutes, when the fire information is adjusted by the user in the use process of the user, for example, when the timing time is 45 minutes, the fire information adjusted by the user is detected to be 3, the valve closing time length threshold corresponding to the fire value 3 is 30 minutes, the new timing time is determined to be 30 minutes according to the changed valve closing time length threshold of 30 minutes, the new timing time is replaced by the new timing time of 30 minutes for 45 minutes, and the timing is restarted.
230. Judging whether the timing time is smaller than or equal to a preset warning value.
In the timing process, starting timing, and judging whether the timing time is smaller than or equal to a preset warning value. The timing is to count down from the timing time, and the preset warning value is a preset time value. The preset alert value may be a fixed time value, for example, the timed time is 90 minutes, the preset alert value is 2 minutes, and the timed time is gradually reduced from 90 minutes after the countdown is started. When the time is greater than the preset warning value for 2 minutes, it may be determined that the preset warning value is not exceeded, and when the time is less than or equal to the preset warning value for 2 minutes, it may be determined that the preset warning value is exceeded.
240. Executing the prompt instruction and sending prompt information.
When the timing time is smaller than or equal to the preset warning value, executing a prompt instruction, sending prompt information, and sending the prompt information every first preset time length value, wherein each time the prompt information lasts for a second preset time length value. The first preset duration value and the second preset duration value may be preset fixed values, and the first preset duration value is 5 seconds and the second preset duration value is 2 seconds as an example. The prompt message may be a preset voice or a preset alarm sound, and the preset voice may be "about to close the valve, please notice the operation" and the preset alarm sound may be "drop, drop … …" alarm sound. The prompt information can be set according to the actual needs of the user, and is not limited herein.
250. And judging whether the timing time reaches the valve closing duration threshold.
In the timing process, starting timing, and judging whether the timing time reaches the valve closing duration threshold. The timing is counted down from the timing time, and when the counted down time returns to zero, the timing time reaches the valve closing duration threshold value.
260. And executing a valve closing instruction when the timing time reaches the valve closing duration threshold.
When the timing time reaches the valve closing time threshold, triggering and executing a valve closing instruction to control the stove to flameout. For example, when the kitchen range is an electromagnetic range, the current of the electromagnetic range coil is cut off, and when the kitchen range is a gas range, the gas range valve body is controlled to be closed, and the gas supply is cut off, so that the gas range is flameout.
When the embodiment of the invention is implemented, when a user starts to use the kitchen range, fire information is detected, after the kitchen range is determined to be in a fire state, fire value information is detected, a valve closing time length threshold value is determined according to the fire value information, timing is started, when the fire value information of the kitchen range changes in the timing process, the valve closing time length threshold value is determined again, timing is restarted, when the timing time reaches a preset warning value, the kitchen range is controlled to send prompt information to prompt the user to operate the kitchen range in time, and when the timing time reaches the valve closing time length threshold value, the kitchen range is controlled to be closed. Therefore, the situation that a user forgets to close the kitchen range after leaving the kitchen range for a long time is avoided, the fact that the valve closing time threshold is unreasonable when the user actually uses the kitchen range is also optimized, the fire power of the kitchen range is readjusted before the timing time reaches the valve closing time threshold so that the fire power value information is changed, the valve closing time threshold corresponding to the fire power value information is also changed, and therefore the reasonable valve closing time threshold is determined to control flameout of the kitchen range, and damage caused by the fact that the kitchen range is in an open state for a long time is also avoided.
