In this step, the first control module obtains a temperature value in the cooking environment detected by the first temperature sensor, and in a possible implementation manner, the first control module periodically obtains the temperature value in the cooking environment detected by the first temperature sensor.
When the dry burning phenomenon occurs in the cooking environment of the gas stove, the local environment temperature can rise, and therefore, the first control module can judge whether the dry burning condition occurs in the gas stove or not by acquiring the temperature value detected by the first temperature sensor.
S602, if the temperature value is greater than or equal to a first preset temperature threshold value and the temperature value is less than or equal to a second preset temperature threshold value, the first control module acquires a distance value between the bracelet and the host machine, which is detected by the first distance sensor.
In this step, after S601, the first control module compares the obtained temperature value with a first preset temperature threshold and a second preset temperature threshold, respectively, and if the obtained temperature value is greater than or equal to the first preset temperature threshold and is less than or equal to the second preset temperature threshold, the first control module obtains a distance value between the bracelet and the host, which is detected by the first distance sensor.
The first preset temperature threshold and the second preset temperature threshold are different temperature values and respectively represent different warning levels, wherein the warning level corresponding to the second preset temperature threshold is higher than the warning level corresponding to the first preset temperature threshold.
When the obtained temperature value is greater than or equal to the first preset temperature threshold value and is less than or equal to the second preset temperature threshold value, the situation that slight dry burning occurs in the cooking environment is described, at the moment, the first control module obtains the distance value between the bracelet and the host machine detected by the first distance sensor, and whether the stove dry burning is intended by a user is determined.
And S603, if the distance value is smaller than the preset distance threshold, the first control module controls the first alarm module to alarm.
In this step, after S602, if the distance value acquired by the first control module is smaller than the preset distance threshold, the first control module controls the first alarm module to alarm.
If the distance value acquired by the first control module is smaller than the preset distance threshold, it indicates that the user is in the direct reachable range of the host, and the host alarms, that is, the first control module controls the first alarm module to alarm.
In one possible implementation manner, the controlling, by the first control module, the first alarm module to alarm includes:
the first control module controls the first loudspeaker to carry out voice reminding.
In this step, because what appears in the culinary art environment is the slight dry combustion method condition, and the user is in the direct reachable scope of host computer, consequently, carry out pronunciation warning through first speaker, remind the user to pay attention to the condition of cooking utensils can.
S604, if the distance value is larger than or equal to the preset distance threshold value, the first control module controls the first communication module to send a prompt message to the second communication module, and the second control module controls the second alarm module to alarm according to the prompt message.
In this step, after S602, if the distance value is greater than or equal to the preset distance threshold, the first control module controls the first communication module to send a prompt message to the second communication module, and the second control module controls the second alarm module to alarm according to the prompt message.
If the distance value acquired by the first control module is greater than or equal to the preset distance threshold value, it indicates that the user is far away from the host computer, and an alarm needs to be given through the bracelet.
In a possible implementation manner, the controlling, by the second control module, the second alarm module to alarm according to the prompt message includes:
and the second control module controls the second loudspeaker to carry out voice reminding according to the prompt message.
In this step, because what appears in the culinary art environment is the slight dry combustion method condition, and is far away from the distance of host computer, consequently, first control module control first communication module sends the suggestion message to second communication module, and second control module is according to the suggestion message, and the control second alarm module is reported an emergency and asked for help or increased vigilance through the bracelet and remind the user to pay attention to the condition of cooking utensils can.
