In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

In order to explain the technical means of the present invention, the following description will be given by way of specific examples.

101. acquiring the current environmental temperature through a thermistor;

specifically, the thermistor is a type of a sensitive element, which is classified into a positive temperature coefficient thermistor PTC and a negative temperature coefficient thermistor NTC according to a temperature coefficient. Thermistors are typically temperature sensitive and exhibit different resistance values at different temperatures. The positive temperature coefficient thermistor PTC has a resistance value which is larger as the temperature is higher, and the negative temperature coefficient thermistor NTC has a resistance value which is lower as the temperature is higher, which are both semiconductor devices. The present embodiment employs a negative temperature coefficient thermistor NTC. The temperature of the NTC is changed when the resistance value is changed, and a temperature change table corresponding to the resistance value can be made according to the characteristic of the NTC.

Further, the thermistor acquiring the current ambient temperature includes: the ADC (Analog-to-digital converter) converts the acquired voltage into a resistance value, and then looks up the temperature degree table according to the resistance value. The span of the temperature degree table can be set to be 10 ℃, the table look-up range is narrowed to be 10 ℃, and therefore the table look-up time is shortened, and the current environment temperature is obtained in time. Continuously collecting temperature values of sampling points: assuming that the sampling is carried out for 10 times, the maximum value and the minimum value are removed, the type is thickened and divided by 8, and the obtained average value of the sampling is the average ambient temperature value of the current sampling point. Setting the current average ambient temperature value as T new, presetting a variable T old, and initially assigning a value of 31.0 ℃.

102. Judging whether to perform temperature compensation according to the change condition of the current environment temperature;

specifically, step 102 includes: acquiring an average ambient temperature value of the current ambient temperature; judging whether the current average ambient temperature value continuously increases within a preset test time, wherein the amplification is greater than or equal to a preset amplification temperature; and if so, performing temperature compensation when the current environment temperature is higher than 40 ℃. Further, it is determined whether T new is greater than T old +0.2 ℃ (0.3 ℃ if greater than 0.2 ℃), and if it is satisfied 7 times in 6 seconds, it is determined that the compensation condition is satisfied when the temperature value reaches 33.1 ℃ or more (31.0 ℃ +0.3 ℃x7 ═ 33.1 ℃), and compensation is performed if the actual temperature is greater than 40 ℃, and no compensation is performed if the actual temperature is less than 40 ℃, thereby preventing false alarm. Further, the average ambient temperature value continuously increases within the preset test time without exceeding the preset comparison value, and specifically, when the method is applied to the embodiment, the preset comparison value is set to increase by 0.2 ℃ per sampling period, and the current ambient temperature is continuously obtained through the thermistor.

103. If so, acquiring a current temperature compensation value according to a temperature compensation table preset based on the Fibonacci number series coefficient;

in a preset time, if the current environment temperature does not reach the temperature compensation value, the temperature compensation value is kept; and if the current environment temperature is reduced to be lower than the preset temperature compensation initial value, the compensation is quitted, and the current environment temperature is displayed.

Specifically, the former partial compensation coefficient among fibonacci number series coefficients (spirals) — { 101%, 103%, 105%, 108%, 113%, 121%, (using 134%, 155%, 189%) … } hardly satisfies the requirement of the compensation period. The segments are multiplied by the actual temperature values and fitted to a temperature compensation table as shown in fig. 4: namely, the temperature of the environment is predicted through a lower actual value, so that the problem of long response time of the temperature sensor is solved. Further, in the preset time, if the current ambient temperature does not reach the temperature compensation value, the maintaining the temperature compensation value may include: judging that the temperature difference between the current environment temperature and the temperature compensation initial value is compared within the preset time; correcting the preset compensation time according to the temperature difference; and if the current environment temperature does not reach the temperature compensation value within the preset compensation time, keeping the temperature compensation value.

Further, if the temperature difference is greater than 10 ℃, shortening the preset supplementary compensation time for 1 second; if the temperature difference is greater than 14 ℃, shortening the preset supplementary compensation time for 2 seconds; if the temperature difference is greater than 18 ℃, shortening the preset supplementing compensation time for 3 seconds; if the temperature difference is greater than 20 ℃, the preset supplementary compensation time is set to 29 seconds. Because the actually tested environment setting temperature is not constant, the interval is between 45 and 140 ℃, and the temperature rising to any temperature in the interval (multiplied by 1.2) from the environment temperature is required to be alarmed within 40s, and the error is not more than 5%. And the compensated value should not be more than 5% of the set ambient temperature, otherwise the temperature displayed is higher than the ambient temperature, which is inaccurate.

Furthermore, the compensation time length is controlled so as to control the accuracy of the temperature after compensation, the initial compensation time length variable is assigned to 22 seconds, after the compensation condition in 5 is judged to be met, the first sampling value of more than 33.1 degrees is stored as an initial value T0, the time is counted from the sampling value, the value after 15 seconds is stored as T1, the temperature difference between T1 and T0, namely the temperature difference of 15 seconds, is used as the compensation time length correction basis of sampling, and the value is shifted by one bit to the right to obtain the correction time length. Based on this correction, the temperature difference T1-T0 is determined again: if the correction time length is more than 10 degrees, the correction time length is shortened by 1 s; shortening by 2s when the temperature is more than 14 degrees; the length is reduced by 3s when the angle is larger than 18 degrees, and is determined as 29s when the angle is larger than 20 degrees.

If the compensation time is used up, the compensation is not carried out until the actual value reaches the compensated value, and the value is kept; if the temperature drops below T0, the compensation is exited and the actual value is displayed. Therefore, the problem of false alarm caused by difficult control of a compensation result is solved, and the following table shows that:

it should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

The method provided by the embodiment can be seen that the temperature change rate of the surrounding environment is acquired by the thermistor to judge whether temperature compensation measures are taken or not so as to achieve the critical value of the alarm temperature in advance through a temperature compensation mode, on one hand, the alarm is performed in advance through the temperature compensation mode, and the fire can be effectively prevented in time; on the other hand, the temperature is compensated by adopting the Fibonacci sequence, so that the speed of temperature change can be more accurate, and the time for alarming the fire alarm bell can be more accurate. The test environment of the method provided by the embodiment is an oven, and due to the fact that the heat conducting performance of liquid such as water, oil and the like is different from that of air, if the compensation method is adopted, the compensation time needs to be adjusted and shortened.

The device provided by the embodiment can also see that the temperature change rate of the surrounding environment is acquired by the thermistor to judge whether to adopt temperature compensation measures or not so as to achieve the critical value of the alarm temperature in advance through a temperature compensation mode, on one hand, the alarm is advanced through the temperature compensation mode, and the fire can be effectively prevented in time; on the other hand, the temperature is compensated by adopting the Fibonacci sequence, so that the speed of temperature change can be more accurate, and the time for alarming the fire alarm bell can be more accurate.
