The processes may correspond to methods, functions, procedures, subroutines, and the like.
At present, a temperature setting alarm is generally adopted for a differential temperature alarm mode of a temperature-sensitive detector, first temperature data obtained after initialization of the temperature-sensitive detector is put into a group of data tables to obtain an initialized temperature data set, and if the temperature data quantity of the initialized temperature data set is i, the temperature data stored in the initialized temperature data set is A1-Ai. After the initialization temperature value group is generated, when the temperature-sensing detector collects the current temperature value, the current temperature value is compared with the average value of i temperature data in the initialization temperature value, and if A is the average value(i+1)-average(A1-Ai)>And delta 1, the temperature-sensitive detector is considered to start to heat up, wherein the delta 1 is the temperature rise rate of the temperature-sensitive detector.

By adopting the differential temperature alarm mode of the temperature-sensitive detector, if the temperature of the temperature-sensitive detector is insensitive, the initial heating rate of the temperature-sensitive detector can be judged wrongly, and further the temperature-sensitive detector can alarm in a delayed mode.
In summary, embodiments of the present invention provide a method and an apparatus for detecting a difference temperature of a thermal detector, and a medium to solve the above problems.
Example one

It can be understood that, in terms of different temperature differences of the temperature-sensitive detector, the alarm temperature-rise rate has a small difference in the initial stage or is difficult to distinguish in the initial stage, so that the determination of the alarm temperature-rise rate in this embodiment is implemented by considering data i seconds before the alarm as the determination, that is, after the temperature-sensitive detector is powered on, generating a temperature value group of i, and setting the initial value on each data bit in the temperature value group as the initial temperature value.

In this embodiment, the curves in different temperature rise ranges are equal to the temperature rise condition in the normal environment, so that the temperature rise alarm point can be selected only by selecting the intermediate value required by the standard, that is, the alarm is performed at a fixed point according to the fixed-temperature alarm mode. Therefore, under the condition that the temperature rise slope is accurately judged, at least one historical temperature rise rate is obtained, and the alarm temperature values corresponding to the historical temperature rise rates are respectively determined, namely, the one-to-one corresponding relation between the historical temperature rise rates and the alarm temperature values is set.
Illustratively, at least one historical temperature rise rate is a historical temperature rise rate K1, a historical temperature rise rate K2, a historical temperature rise rate Kj of … …, j is a positive integer, the corresponding alarm temperature values are alarm temperature values T1, T2, … …, and the historical temperature rise rates correspond to the alarm temperature values one to one.
It can be understood that, since the historical temperature rise rates and the alarm temperature values are set in one-to-one correspondence, the number of the historical temperature rise rates is the same as the number of the alarm temperature values. The number of the historical temperature increase rates may be one, two or more, and the present embodiment does not specifically limit the number of the historical temperature increase rates.
S130, determining whether the temperature-sensitive detector generates a difference temperature alarm signal according to the current heating rate, and controlling the temperature-sensitive detector to alarm according to the difference temperature alarm signal.
Specifically, when the temperature rise rate of the environment around the temperature-sensitive detector is too fast or rapidly increases in a short time, the temperature-sensitive detector generates a difference temperature alarm signal, and the difference temperature alarm signal is used for controlling the temperature-sensitive detector to give an alarm to the external environment.
The alarm mode of the temperature-sensitive detector can be acousto-optic alarm or acoustic alarm, the specific alarm mode of the temperature-sensitive detector is not limited at all, and the specific alarm mode of the temperature-sensitive detector can be flexibly set by selecting the existing alarm mode.
On the basis of the above embodiment, determining whether the temperature-sensitive detector generates a differential temperature alarm signal according to the current temperature-rise rate includes: and if the current temperature rise rate is smaller than the historical temperature rise rate and the current temperature value is smaller than the alarm temperature value, determining that the temperature-sensitive detector is not triggered to generate a differential temperature alarm signal. And if the current heating rate is greater than or equal to the historical heating rate and the current temperature value is greater than or equal to an alarm temperature value, determining that the temperature-sensing detector is triggered to generate a differential temperature alarm signal. Further, the method for detecting the difference temperature of the temperature sensitive detector further comprises: and replacing the initial temperature value of the initial temperature value set with the current temperature value, and generating a target temperature value set, wherein the target temperature value set comprises the current temperature value.

S230, detecting the current temperature value of the temperature-sensitive detector in real time, and determining the current heating rate of the temperature-sensitive detector according to the current temperature value and the initial temperature value.
On the basis of the above embodiment, determining the current temperature-increasing rate of the temperature-sensitive detector according to the current temperature value and the initial temperature value includes:
