Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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.
For the problem that the existing flame detection method detects false fire, analysis shows that two situations generally exist before flame detection. Case 1: the gas range is turned off for a long time before the flame detection. Because no flame heats the thermocouple for a long time, the temperature of the thermocouple is low, and the voltage at two ends of the thermocouple flame detection circuit is low when the existing flame detection method is adopted to detect the flame by the thermocouple. After the ignition is finished, because flame heats the thermocouple, the voltage at two ends of the thermocouple flame detection circuit is increased, and when the temperature value detected by the thermocouple is greater than the lowest temperature value when flame exists, the flame can be detected. Case 2: the gas burner is turned off a short time before the flame detection, e.g. by cooking a dish with the gas burner, and turning off the gas burner after cooking one dish, but immediately before cooking a second dish, the gas burner needs to be turned on again. At the moment, when flame detection is carried out in the ignition process, the thermocouple is just heated, so the temperature of the thermocouple is higher, when the existing flame detection method is adopted to carry out detection by adopting the thermocouple, the voltage at two ends of a flame detection circuit of the thermocouple is higher before ignition is successful, so the temperature detected by the thermocouple is also higher, if the temperature value detected by the thermocouple is greater than the lowest temperature value when flame exists, the flame exists, but no flame exists in the actual situation, and the condition of false flame occurs.
Example 1
The invention provides a flame detection method in embodiment 1, and fig. 1 is a schematic flow chart of the flame detection method in embodiment 1. As shown in fig. 1, the flame detection method according to embodiment 1 of the present invention includes the steps of:
s101: and acquiring a first temperature value of the furnace end at the current moment.
As a specific implementation mode, a thermocouple is used for obtaining a first temperature value of the furnace end at the current moment.
S102: and judging whether the first temperature value is greater than a first preset threshold value.
As a specific embodiment, the first preset threshold is a minimum temperature value when the burner has a flame.
S103: and when the first temperature value is greater than the first preset threshold value, acquiring a plurality of temperature values of the furnace end in a first preset time period after the current time.
In embodiment 1 of the present invention, the length of the first preset time period may be set according to specific situations, and the present invention is not limited, and the frequency of obtaining the temperature value is also not limited, and only a plurality of temperature values can be obtained in the first preset time period.
S104: when the temperature values are all larger than the first temperature value, the furnace end is judged to have flame.
In the flame detection method provided in embodiment 1 of the present invention, when the first temperature value is greater than the first preset threshold, it is not directly determined that there is a flame at the furnace end, but it is continuously determined whether a plurality of temperature values of the furnace end in the first preset time period after the current time are all greater than the first temperature value, and when the temperature values are all greater than the first temperature value, it is determined that there is a flame, so that the true condition that there is a flame at the furnace end can be reflected by the plurality of temperature values in the first preset time period after the current time, and detection of a false fire is avoided.
Example 2
The invention provides a flame detection method in embodiment 2, and fig. 2 is a schematic flow chart of the flame detection method in embodiment 2 of the invention. As shown in fig. 2, the flame detection method according to embodiment 2 of the present invention includes the steps of:
s201: and acquiring a first temperature value of the furnace end at the current moment.
S202: and judging whether the first temperature value is greater than a first preset threshold value. When the first temperature value is greater than the first preset threshold, go to step S203, and when the first temperature value is less than the first preset threshold, go to step S204. The first preset threshold value is the lowest temperature value of the furnace end when flame exists.
S203: and acquiring a plurality of temperature values of the furnace end in a first preset time period after the current time, and judging whether the plurality of temperature values are all larger than the first temperature value. When the temperature values are all larger than the first temperature value, determining that flame exists at the furnace end; and when at least one of the temperature values is smaller than the first temperature value, returning to the step S202.
As a specific implementation manner, the obtaining of the plurality of temperature values of the furnace end in the first preset time period after the current time is as follows: and sequentially acquiring each temperature value of the furnace end in the first preset time period.
As a specific implementation manner, when any temperature value of the first preset time period is smaller than the first temperature value, the temperature value is taken as the first temperature value, and the step S202 is returned to. In step S203, in the embodiment 2 of the present invention, a manner of sequentially obtaining and sequentially determining a plurality of temperature values in a first preset time period is adopted, so that a flame real situation including a flame size change can be truly reflected. For example, in the working engineering of a gas stove, after the fire is turned off, a certain temperature value in a first preset time period may be smaller than a first temperature value, and at this time, by readjusting the first temperature value and taking the temperature value at this time as a new first temperature value, the flame can still be detected, and the actual condition of the flame can be reflected.
Assuming that the length of the first preset time period is 5S, 300 temperature values can be obtained in one of the first preset time periods according to the preset frequency. As an example, step 203 may be implemented as follows: obtaining the 1 st temperature value, judging whether the 1 st temperature value is greater than the first temperature value, when greater than, continuing to obtain the 2 nd temperature value, and judging whether the 2 nd temperature value is greater than the first temperature value, analogizing in turn until obtaining the 300 th temperature value, and judging whether the 300 th temperature value is greater than the first temperature value, when the 300 th temperature value is greater than the first temperature value, judging that the furnace end has flame. However, when the 50 th temperature value is smaller than the first temperature value, the 51 st temperature value is not acquired any more, the 50 th temperature value is taken as the first temperature value, and the process returns to step S202.
S204: acquiring a plurality of temperature values of the furnace end in a second preset time period after the current time; and when the temperature values are all larger than the second preset threshold value, judging that the furnace end has flame. And when at least one of the temperature values is smaller than the second preset threshold value, returning to the step S202.
As a specific implementation manner, the first preset threshold and the second preset threshold are the same and are the lowest temperature values when the burner has flames.
As a specific implementation manner, the second preset time period is smaller than the first preset time period.
As a specific implementation manner, the obtaining of the plurality of temperature values of the furnace end in the second preset time period after the current time is as follows: and sequentially acquiring each temperature value of the furnace end in the first preset time period.
As a specific implementation manner, when any temperature value in the second preset time period is smaller than the second preset threshold, the temperature value is taken as the first temperature value, and the step S202 is returned to.
Assuming that the length of the second preset time period is 500mS, 10 temperature values can be obtained in one of the second preset time periods according to the preset frequency. As an example, step 203 may be implemented as follows: obtaining a 1 st temperature value, judging whether the 1 st temperature value is greater than a second preset threshold value, when the 1 st temperature value is greater than the second preset threshold value, continuously obtaining a 2 nd temperature value, judging whether the 2 nd temperature value is greater than the second preset threshold value, analogizing in sequence until a 10 th temperature value is obtained, judging whether the 10 th temperature value is greater than the second preset threshold value, and when the 10 th temperature value is greater than the second preset threshold value, judging that the furnace end has flame. However, when the 5 th temperature value is smaller than the second preset threshold, the 6 th temperature value is no longer acquired, the 5 th temperature value is taken as the first temperature value, and the process returns to step S202.
