In one embodiment, the information detected by the infrared probe is first converted into a temperature value H. And comparing H with A, if H is less than A, the temperature of the whole machine is not problematic, and continuing monitoring. If H is larger than or equal to A, an alarm is given; and comparing H with B, and if H is less than B, the temperature of the whole machine is in a first-level early warning temperature range, and only giving an alarm. If H is larger than or equal to B, the running power of the whole machine is reduced; and comparing H with C, if H is less than C, the temperature of the whole machine is in a secondary early warning temperature range, the running power of the whole machine is reduced, and the whole machine is switched to a normal running state when the temperature in the standby mode reaches the safe temperature. If H is larger than or equal to C, the whole machine enters a three-level early warning temperature, a fire hazard exists, the operation is immediately stopped, and an emergency device is started. Wherein, the comparison temperature plan sets three levels, namely A, B, C, specifically, the first-level early warning temperature is a; the secondary early warning temperature is B; the third-level early warning temperature is C, and the specific temperature can be flexibly selected according to the actual needs of the whole machine.
And outputting a corresponding program to control the operation of the early warning equipment after the data analysis is finished, wherein the early warning equipment comprises a communicator, a frequency reduction program, a circuit breaker and an emergency device.

In the above embodiment, the control mode is basically a knife-cut control according to the range of the target temperature, the target temperature exceeds the corresponding set temperature to trigger output, and the output is stopped when the target temperature is lower than the set temperature, which may cause frequent early warning and is not favorable for stable control of the air conditioner. Three examples are given below, the difficulty of which gradually increases and the effect of which gradually becomes better.
In one embodiment: under the condition that the target temperature is in the preset temperature range, determining whether the change state of the target temperature meets the preset condition or not, wherein the step comprises the following steps: determining whether the duration of the target temperature within the preset temperature range reaches a first preset duration; determining that the change state of the target temperature meets a preset condition under the condition that the time length of the target temperature in a preset temperature range reaches a first preset time length; and under the condition that the time length of the target temperature in the preset temperature range does not reach a first preset time length, determining that the change condition of the target temperature does not accord with the preset condition. In specific implementation, a timer is added behind the comparator, and corresponding output can be triggered only after the temperature meets a certain condition and is kept for a certain time. Conversely, the same is true when the alarm is cleared, and the alarm can be cleared only if the temperature falls below the set temperature and remains for a certain time.
In another embodiment: under the condition that the target temperature is in the preset temperature range, determining whether the change state of the target temperature meets the preset condition or not, wherein the step comprises the following steps: determining whether the integral of the difference value of the target temperature and the lower limit value of the preset temperature range within a second preset time period reaches a preset value; under the condition that the integral of the difference value between the target temperature and the lower limit value of the preset temperature range within a second preset time period reaches a preset value, determining that the change state of the target temperature meets the preset condition; and under the condition that the integral of the difference value between the target temperature and the lower limit value of the preset temperature range in a second preset time period does not reach a preset value, determining that the change state of the target temperature does not accord with the preset condition. In specific implementation, a subtracter and an integrator are added behind the comparator, the subtracter is used for calculating the difference value between the target temperature and the set temperature, and the integrator is used for calculating the area of the part of the target temperature exceeding the set temperature. The problem of frequent start can be effectively solved by integration, the quantity exceeding the temperature limit value can be expressed in numerical value according to the integration, and early warning is triggered when the quantity reaches a certain value. Taking the first-level early warning as an example, when H is more than or equal to A, the calculation is started
And setting an integral limit value D if
The pre-warning is initiated. On the contrary, when the early warning is eliminated, whether H is less than A is judged, if yes, integral is calculated, and if not, integral is calculated
The pre-warning is eliminated.
In a last embodimentThe method comprises the following steps: under the condition that the target temperature is in the preset temperature range, determining whether the change state of the target temperature meets the preset condition or not, wherein the step comprises the following steps: determining whether the rising rate of the target temperature reaches a preset rate; determining that the change state of the target temperature meets a preset condition under the condition that the rising rate of the target temperature reaches a preset rate; under the condition that the rising rate of the target temperature does not reach the preset rate, determining whether the integral of the difference value of the target temperature and the lower limit value of the preset temperature range within a second preset time period reaches a preset value; and under the condition that the integral of the difference value between the target temperature and the lower limit value of the preset temperature range in a second preset time period reaches a preset value, determining that the change state of the target temperature meets the preset condition. In specific implementation, a differentiator is added behind a comparator, early warning can be performed on rapid temperature rise in a short time by differentiating first, if the temperature rise rate is slow, an integral method is still used, and if the temperature rise rate exceeds a set value, early warning is directly started. Compared with slow temperature rise, the damage caused by rapid temperature rise in a short time is larger and more serious, early warning is needed, if a timer or an integral method is still used, early warning can be delayed, and particularly, when secondary early warning and tertiary early warning are carried out, the rapid temperature rise needs to be subjected to emergency frequency reduction or circuit breaking. Taking a two-stage early warning example, a rapid temperature rise limit value E is set, and when H is larger than or equal to B, calculation is started
If it is
Directly starting secondary early warning if
Then calculate
If it is
