It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof.
It should be further noted that, for convenience of description, only some, but not all of the matters related to the present invention are shown in the accompanying drawings. Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently, or at the same time.

The differential temperature detection method of the temperature sensor specifically comprises the following steps:
s110, acquiring an initial temperature value group of the temperature sensing detector, wherein the initial temperature value group comprises i initial temperature values, and i is a positive integer.
The temperature sensor in this embodiment is a differential temperature sensor, that is, a fire sensor that starts an alarm when the rate of temperature rise due to a fire exceeds a predetermined value within a predetermined period of time.
The initial temperature value may be a first set of temperature values collected by the temperature sensor after the temperature sensor is powered on, and on this basis, the first set of temperature values (i.e., the initial temperature values) are used as initial values in the initial temperature value set, so as to avoid misjudgment of temperature rise possibly caused under different temperature difference conditions, thereby improving accuracy of subsequent temperature rise rate judgment.
The initial temperature value is obtained by converting the detected temperature change into an electric signal by the temperature sensing detector, namely, the initial temperature value is determined by converting an analog quantity into a digital quantity and then determining the corresponding temperature value.
On the basis of the above embodiment, acquiring the initial temperature value set of the temperature sensing detector includes: after the temperature sensing detector is electrified, generating a temperature value group with the number of i, and acquiring an initial temperature value of the temperature sensing detector, wherein i is a positive integer; and storing the initial temperature value into a corresponding data bit in the temperature value group to obtain an initial temperature value group, wherein the initial temperature value group comprises i initial temperature values.
Specifically, after the temperature sensing detector is powered on, a temperature value group with the number of i is generated, the temperature value group can be known to comprise i data bits, a first group of temperature values acquired by the temperature sensing detector, namely initial temperature values, are obtained, initial values of all data bits in the temperature value group are initial temperature values, and the temperature value group consists of i initial temperature values.
It can be understood that, under different temperature differences of the temperature sensing detector, the alarm heating rate is less different in the initial stage or is difficult to distinguish in the initial stage, so that the judgment of the alarm heating rate in this embodiment is realized by taking the data i seconds before the alarm into consideration as the judgment, that is, after the temperature sensing detector is powered on, generating a temperature value group with the number of i, and taking each data bit in the temperature value group as an initial temperature value.

Specifically, under the condition of considering actual temperature sensing alarm, the temperature rise speed is fast, the temperature sensing is not enough to exchange heat, the temperature of the thermistor of the temperature sensing detector has reached a very high temperature, at this time, the alarm condition during the rapid temperature rise can be timely and accurately judged by adopting the current temperature rise rate calculation mode, and the application range of the differential temperature detection mode of the embodiment is wider and the application scene is richer.
Further, on the basis of the above embodiment, before detecting the current temperature value of the temperature sensing detector in real time, the method further includes: and acquiring at least one historical heating rate, and respectively determining alarm temperature values corresponding to the historical heating rates.
In this embodiment, the curves in different temperature rising ranges are equal to the temperature rising conditions in the normal environment, so that the temperature rising alarm point can be selected only by selecting the middle value required by the standard, namely, the alarm is set according to the alarm mode of the fixed temperature. Therefore, under the condition that the temperature rise slope is accurately judged, at least one historical temperature rise rate is obtained, and alarm temperature values corresponding to the historical temperature rise rates are respectively determined, namely, one-to-one correspondence between the historical temperature rise rates and the alarm temperature values is set.
Illustratively, at least one of the historical heating rates is a historical heating rate K1, a historical heating rate K2, and a historical heating rate Kj of … …, j is a positive integer, and the corresponding alarm temperature values are an alarm temperature value T1, an alarm temperature value T2, and an alarm temperature value Tj of … …, respectively, and the historical heating rates are in one-to-one correspondence with the alarm temperature values.
It can be understood that, since the historical heating rates are set in one-to-one correspondence with the alarm temperature values, the number of the historical heating rates is the same as the number of the alarm temperature values. The number of the historical temperature rise rates may be one, two or more, and the number of the historical temperature rise rates is not particularly limited in this embodiment.
S130, determining whether the temperature sensing detector generates a differential temperature alarm signal according to the current temperature rising rate so as to control the temperature sensing detector to alarm according to the differential temperature alarm signal.
Specifically, when the temperature rising rate of the surrounding environment of the temperature sensing detector is too fast or the temperature rising rate is fast increased in a short time, the temperature sensing detector generates a differential temperature alarm signal, and the differential temperature alarm signal is used for controlling the temperature sensing detector to give an alarm to the external environment.
The alarm mode of the temperature sensing detector can be sound-light alarm or sound alarm, the alarm mode of the specific temperature sensing detector is not limited, and the alarm mode of the specific temperature sensing detector can be flexibly set by selecting the existing alarm mode.
On the basis of the above embodiment, determining whether the temperature sensing detector generates a differential temperature alarm signal according to the current temperature rising rate includes: and if the current temperature rising rate is smaller than the historical temperature rising rate and the current temperature value is smaller than the alarm temperature value, determining that the temperature sensing detector is not triggered to generate a differential temperature alarm signal. And if the current temperature rising rate is greater than or equal to the historical temperature rising rate and the current temperature value is greater than or equal to the alarm temperature value, determining that the temperature sensing detector triggers to generate a differential temperature alarm signal. Further, the differential temperature detection method of the temperature sensing detector further comprises the following steps: and replacing the initial temperature value of the initial temperature value group with the current temperature value, and generating a target temperature value group, wherein the target temperature value group comprises the current temperature value.
According to the technical scheme, the initial temperature value group of the temperature sensing detector is obtained, wherein the initial temperature value group comprises i initial temperature values, and i is a positive integer; detecting the current temperature value of the temperature sensing detector in real time, and determining the current temperature rising rate of the temperature sensing detector according to the current temperature value and the initial temperature value; and determining whether the temperature sensing detector generates a differential temperature alarm signal according to the current temperature rising rate so as to control the temperature sensing detector to alarm according to the differential temperature alarm signal. The temperature difference alarm method solves the problems that the existing temperature difference alarm method depends on the temperature sensitivity of the temperature sensing detector, the temperature difference alarm algorithm is complex, and the number of algorithm programs is huge, so that the temperature rise of the temperature sensing detector is accurately judged, and the temperature difference alarm precision of the temperature sensing detector is improved.
