Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, when the oven is used for the first time or is preheated, a user can open a door and bake to remove peculiar smell or protective oil inside the oven, but the user forgets to turn off the oven door body easily due to various reasons, the door body is opened for a long time, resources are wasted, equipment is damaged, and great potential safety hazards exist. Therefore, the oven alarm method can avoid resource waste and improve safety.
The embodiment of the invention discloses an oven alarm method, which is shown in figure 1 and comprises the following steps:
step S11: acquiring numerical values of a first temperature sensor and a second temperature sensor of a target oven to obtain a first sensor numerical value and a second sensor numerical value; the first temperature sensor and the second temperature sensor are respectively arranged in a first preset area and a second preset area of the target oven.
In this embodiment, a first sensor value and a second sensor value corresponding to each other are obtained by a first temperature sensor and a second temperature sensor. It is understood that the first temperature sensor and the second temperature sensor are respectively disposed in a first preset area and a second preset area of the target oven, for example, the first preset area is a top area, and the second preset area is a bottom area. The sensor values can be obtained directly from the corresponding sensors.
Step S12: comparing the first sensor value to a first pre-acquired target sensor value and comparing the second sensor value to a second pre-acquired target sensor value.
In this embodiment, the first sensor value is compared with a first target sensor value obtained in advance, and the second sensor value is compared with a second target sensor value obtained in advance. It will be appreciated that the first target sensor value and the second target sensor value are pre-acquired parameter values, including values obtained after a number of experimental tests under different environmental conditions. The current sensor value obtained by one sensor is compared with the pre-obtained target sensor value, and since the historical sensor values of the target oven in safe and unsafe states, such as the historical sensor values of the target oven in door opening and door closing, can be recorded in the pre-test process, the target sensor values are calculated according to the safe historical sensor values and the unsafe historical sensor values, that is, whether the target oven is in an unsafe state or not can be judged according to the comparison result.
Step S13: and when the first sensor value is smaller than the first target sensor value and the second sensor value is smaller than the second target sensor value, judging that the current state of the target oven is an unsafe state and giving an alarm.
In this embodiment, when the first sensor value is smaller than the first target sensor value and the second sensor value is smaller than the second target sensor value, it is determined that the current state of the target oven is an unsafe state and an alarm is issued. It is understood that, during the same time period, if the first sensor value is smaller than the first target sensor value and the second sensor value is smaller than the second target sensor value, the current state of the target oven is determined to be an unsafe state and an alarm is given. It can be understood that the above-mentioned determination operation is performed a plurality of times at different times, and when the number of times of determining that the target oven is unsafe is greater than 1, the current state of the target oven is determined to be an unsafe state and an alarm is given.
In a specific embodiment, as shown in fig. 2, T is time, θ is a sensor value, when Δ 3 > Δ1 and Δ 4 > Δ2 and Δ 3- Δ 1 > Δ4- Δ 2, the target oven is determined to be in a safe state, and if any one of the above conditions is not satisfied, the target oven is determined to be in an unsafe state and an alarm is given. Specifically, a change difference value of the sensor values in the safe state of the target oven in two adjacent time periods is obtained to obtain a first change difference value and a third change difference value, and a variation between the first change difference value and the third change difference value is calculated to obtain a first variation; acquiring a variation difference value of the sensor values in the unsafe state of the target oven in the same two adjacent time periods to obtain a second variation difference value and a fourth variation difference value, and calculating a variation between the second variation difference value and the fourth variation difference value to obtain a second variation; acquiring a variation difference value of the sensor values of the target oven in the same two adjacent time periods to obtain a fifth variation difference value and a sixth variation difference value, and calculating a variation between the fifth variation difference value and the sixth variation difference value to obtain a target variation; and comparing the target variable quantity with the first variable quantity and the second variable quantity respectively, when the target variable quantity is smaller than the first variable quantity, determining that the current state of the target oven is an unsafe state, and when the target variable quantity is larger than the second variable quantity, determining that the current state of the target oven is a safe state. It can be understood that the sensor values of the target oven are detected at different time points, and if the number of times that the pre-acquired target sensor values in the safe state are not reached is more than 1 time, the target oven is determined to be in the unsafe state.
Therefore, the application provides an oven alarm method, which comprises the following steps: acquiring numerical values of a first temperature sensor and a second temperature sensor of a target oven to obtain a first sensor numerical value and a second sensor numerical value; the first temperature sensor and the second temperature sensor are respectively arranged in a first preset area and a second preset area of the target oven; comparing the first sensor value with a first pre-acquired target sensor value and comparing the second sensor value with a second pre-acquired target sensor value; and when the first sensor value is smaller than the first target sensor value and the second sensor value is smaller than the second target sensor value, judging that the current state of the target oven is an unsafe state and giving an alarm. Therefore, the acquired current sensor value is compared with the pre-acquired target sensor value, and when the comparison result meets the preset condition, the target oven is judged to be in an unsafe state and gives an alarm, so that resource waste is avoided and the safety is improved.
Referring to fig. 3, the embodiment of the invention discloses an oven alarm method, and compared with the previous embodiment, the embodiment further describes and optimizes the technical scheme.
Step S21: acquiring numerical values of a first temperature sensor and a second temperature sensor of a target oven to obtain a first sensor numerical value and a second sensor numerical value; the first temperature sensor and the second temperature sensor are respectively arranged in a first preset area and a second preset area of the target oven.
Step S22: and acquiring the first target sensor value and the second target sensor value under different environmental conditions, and recording the corresponding relation between the corresponding environmental conditions and the target sensor values to obtain a target corresponding table.
In this embodiment, the first target sensor value and the second target sensor value under different environmental conditions are obtained, and the correspondence between the corresponding environmental conditions and the target sensor values is recorded, so as to obtain a target correspondence table. It is understood that the target correspondence table is a table for representing the correspondence between the parameter values acquired in advance and the environment. The first temperature sensor (such as the heating pipe) and the second temperature sensor (such as the heating pipe) are respectively subjected to temperature rise tests in an unsafe state and a safe state, and the respective change rates are respectively obtained. It will be appreciated that the presence or absence of food in the oven has no effect on the parameter results when testing relevant data under unsafe conditions. When the related data under the safe state is tested, the food in the oven affects the parameter result obtained by the test, and if the food, especially the food with high heat absorption capacity (such as frozen chicken) exists in the oven, the related parameters obtained by the test are more accurate. The heating rate of baking in unsafe conditions is different in different seasons (temperatures) and different humidity. (because of the different seasons, different indoor temperatures and humidities, which affect the heating system, resulting in different rates of change of the sensor values). It is noted that the oven is provided with a humidity sensor, the environmental conditions such as temperature and humidity. Specifically, under the same humidity environment, the first target sensor value and the second target sensor value corresponding to different external temperatures are obtained; and acquiring the values of the first target sensor and the second target sensor corresponding to different humidities in the same external temperature environment. When the target oven is in a safe state, respectively acquiring sensor values of a target time period based on the first temperature sensor and the second temperature sensor, and determining a first safety sensor value and a second safety sensor value under different environmental conditions; when the target oven is in an unsafe state, acquiring the sensor values of the target time period based on the first temperature sensor and the second temperature sensor respectively, and determining a first unsafe sensor value and a second unsafe sensor value under different environmental conditions; respectively calculating based on the first safe sensor value and the first unsafe sensor value through a preset calculation formula to obtain each first target sensor value respectively corresponding to different environmental conditions; and respectively calculating based on the second safe sensor value and the second unsafe sensor value through the preset calculation formula to obtain the second target sensor values respectively corresponding to different environmental conditions.
For example, the temperature sensor is tested for unsafe state and safe state temperature rise in different seasons (spring, summer, autumn and winter) and extreme temperatures, and respective change rates are obtained. Determining different temperatures representing different seasons (t 1-t 2), determining different humidities (phi 1-phi 2); in different seasons and under different humidity (phi), the first temperature sensor and the second temperature sensor are respectively subjected to unsafe state and safe state temperature rise tests, and respectively obtain respective corresponding change rates, and a plurality of results are obtained under each method, as shown in fig. 4, for example, when the temperature is t1, the change rates obtained under different humidity conditions are respectively ABCDEF, and the change rates corresponding to different humidity under each temperature condition are obtained. It should be noted that, if the difference between the data at each temperature and each humidity is greater than the preset difference, as shown in fig. 5, for example, when the temperature is t1 and the humidity is Φ 1, the device enters logic 1 (i.e., the currently obtained value is compared with the target sensor value corresponding to the target corresponding table and the current environmental condition), that is, when the device recognizes that the room temperature is t1, the device enters logic of corresponding humidity, and if the change rate meets the parameters of respective logic, the current state of the target oven is determined to be an unsafe state and an alarm is issued. If the difference between the data is smaller than the predetermined difference in some cases through the data comparison, the above logic can be simplified as the logic shown in fig. 6, that is, within a temperature range (e.g., t1-t 2), different humidity ranges having the difference between the data smaller than the predetermined difference are integrated into a humidity range (e.g., Φ 1- Φ 2), and the above humidity range corresponds to a parameter judgment logic.
As shown in FIG. 7, when the currently tested sensor is the first sensor, the time is safe (e.g., door closed)Tm is the rate of change θ 1 The value ranges are as follows:
when the safe (e.g. door closed) time is Tm, the rate of change θ 2 The value ranges are as follows:
calculating to obtain the value of the first target sensor through a preset calculation formula, wherein the preset calculation formula is as follows:
if Δ 1>Δ3，Δ2>Δ 4, determining the value range of θ (namely the first target sensor value) as
When the sensor currently being tested is the second sensor, when the safe time is Tm, the rate of change θ 1’ The value ranges are as follows:
when the safe time is Tm, the rate of change θ 2’ The value ranges are as follows:
and calculating to obtain the value of the second target sensor through a preset calculation formula, wherein the preset calculation formula is as follows:
if Δ 1>Δ3，Δ2>Δ 4, then determine θ ’ The value ranges of (i.e., the second target sensor values) are as follows:
it can be understood that, since the sensor value change rate of the oven in the unsafe state and the safe state is tested at different times, the image shown in fig. 8 can be obtained according to experimental values, and since the values obtained each time are not completely the same, the safe discrete range and the unsafe discrete range can be divided according to the values obtained by testing, such as the shaded portion in the figure. And if the sensor value theta of the target oven currently acquired at a certain moment falls in the area A in the graph, judging the current angle of the oven door, testing at different time, and if the unsafe times are more than 1, judging the oven door to be in an unsafe state. It can be understood that certain food needs a special angle under the influence of factors such as cavity, temperature and the like to achieve a better baking effect, for example, different baking effects are controlled through different opening angles of the oven door body, so that if the acquired sensor value θ of the target oven falls in the area a in the graph, the current angle of the oven door is determined, and the current oven door is further determined according to actual conditions. Specifically, if some food needs a special angle to achieve a better baking effect, at this time, alarm judgment cannot be performed directly according to the fact that the oven is completely closed and opened, so that an opening angle of the maximum angle allowed in the current baking process needs to be set, a first target sensor value and a second target sensor value are obtained through a pre-experiment when the door angle is the opening angle, a first sensor value and a second sensor value are obtained in formal baking, then the first sensor value and the second sensor value are respectively compared with the first target sensor value and the second target sensor value obtained in advance under the opening angle, when the first sensor value is smaller than the first target sensor value and the second sensor value is smaller than the second target sensor value, it is determined that the current state of the target oven is an unsafe state and an alarm is given, and at this time, the angle of the oven door is larger than the opening angle. If the first sensor value is not smaller than the first target sensor value and the second sensor value is smaller than the second target sensor value, namely the oven is in a door closing state or the angle of the oven door body is smaller than the door opening angle, the oven is judged to be in a safe state, and no alarm is given.
It can be understood that the first target sensor value and the second target sensor value of the oven, which are acquired in advance, are set according to actual conditions. The first target sensor value and the second target sensor value obtained in advance can be values when the oven door body is completely closed, and can also be values when the oven door body is opened at a certain angle.
Step S23: determining a current environmental condition of the target oven.
In this embodiment, the current environmental conditions of the target oven are determined. It is understood that the current environmental conditions of the target oven are determined. I.e., determining the current temperature and current humidity of the target oven.
Step S24: and matching the current environmental conditions with the environmental conditions in the target corresponding table to obtain matched environmental conditions.
In this embodiment, the corresponding environmental conditions are queried in the target correspondence table according to the current temperature and the current humidity of the target oven, that is, the environmental conditions with the same temperature and humidity or any one or more of the temperature and the humidity are within a certain environmental condition range in the target correspondence table.
Step S25: comparing the first sensor value with a first target sensor value corresponding to the matched environmental condition, and comparing the second sensor value with a second target sensor value corresponding to the matched environmental condition.
In this embodiment, the first sensor value is compared with a first target sensor value corresponding to the matched environmental condition, and the second sensor value is compared with a second target sensor value corresponding to the matched environmental condition. It is understood that when any one or more of the first sensor value less than the first target sensor value and the second sensor value less than the second target sensor value are not satisfied, the current state of the target oven is determined to be a safe state, and the operation of the target oven is maintained.
In a specific implementation mode, when the temperature is in the middle of t1 to t2, the corresponding humidity logic is entered, then the corresponding logic is entered according to the humidity judgment, namely when the equipment identifies that the room temperature is t1-t2 or t3-t4 or t5-t6, the equipment enters the logic of humidity (phi 1-phi 2) and the like, and if the change rate meets the parameters in the logic 1 to the logic 3, the current state of the target oven is determined to be an unsafe state and an alarm is given.
Step S26: and when the first sensor value is smaller than a first target sensor value corresponding to the matched environmental condition and the second sensor value is smaller than a second target sensor value corresponding to the matched environmental condition, judging that the current state of the target oven is an unsafe state and giving an alarm.
In this embodiment, when the first sensor value is smaller than the first target sensor value corresponding to the matched environmental condition and the second sensor value is smaller than the second target sensor value corresponding to the matched environmental condition, it is determined that the current state of the target oven is an unsafe state and an alarm is given. It should be noted that, after the current state of the target oven is identified as the unsafe state and an alarm is given, when the oven door is closed and the oven door continues to operate, certain food may have a requirement on the temperature compensation time, and the short compensation time may result in poor food effect. Therefore, after the door is closed, the oven automatically judges whether the current state is changed from the unsafe state to the safe state, and when the oven door body is identified to be closed, namely the current state of the target oven is the safe state, a rapid heating program is started.
For the specific content of the step S21, reference may be made to the corresponding content disclosed in the foregoing embodiment, and details are not repeated herein.
Therefore, the numerical values of the first temperature sensor and the second temperature sensor of the target oven are obtained, so that the numerical value of the first sensor and the numerical value of the second sensor are obtained; the first temperature sensor and the second temperature sensor are respectively arranged in a first preset area and a second preset area of the target oven; acquiring the first target sensor value and the second target sensor value under different environmental conditions, and recording the corresponding relation between the corresponding environmental conditions and the target sensor values to obtain a target corresponding table; determining a current environmental condition of the target oven; matching the current environmental condition with the environmental condition in the target corresponding table to obtain a matched environmental condition; comparing the first sensor value with a first target sensor value corresponding to the matched environmental condition, and comparing the second sensor value with a second target sensor value corresponding to the matched environmental condition; and when the first sensor value is smaller than a first target sensor value corresponding to the matched environmental condition and the second sensor value is smaller than a second target sensor value corresponding to the matched environmental condition, judging that the current state of the target oven is an unsafe state and giving an alarm, so that resource waste is avoided and the safety is improved.
