It should be noted that the term "coupled" is to be interpreted broadly, as being able to be coupled directly or indirectly via an intermediary, unless explicitly stated or defined otherwise. The specific meaning of the terms in the embodiments of the invention will be understood by those of ordinary skill in the art in a specific context.
The power-off control method, the power-off control device, the electronic equipment and the storage medium of the air conditioner are described below with reference to fig. 1 to 3.
Specifically, the invention provides a power-off control method of an air conditioner, which is shown in combination with fig. 1, and comprises the following steps:
step S100, acquiring an air conditioner shutdown signal;
specifically, the user can send a shutdown signal to the air conditioner through a control device such as a remote controller or the like, or the user sets an automatic shutdown program, and when the air conditioner operates to a set time, the shutdown signal of the air conditioner is generated and shutdown is performed.
It should be noted that, the shutdown signal of the air conditioner in this embodiment refers to that the air conditioner shuts down the compressor, the fan, the controller, etc. after receiving the shutdown signal, and when the air conditioner operates to a set temperature without cooling or heating, the air conditioner does not belong to the shutdown signal in this embodiment.
Step 200, recording a set temperature value of the air conditioner at the shutdown time;
specifically, when the air conditioner is shut down, a set temperature value of the air conditioner at the shut down time is recorded. For example, when the air conditioner is cooling or heating at a set temperature of 23 ℃, the set temperature is stored.
Step S300, acquiring an indoor temperature value once every preset time interval;
specifically, after the shutdown signal of the air conditioner is obtained, the indoor temperature value is obtained once every preset time. For example, the indoor temperature value is detected every half an hour and transmitted to the controller, with the interval time ranging from 0.4 hours to 0.6 hours, preferably 0.5 hours.
Step S400, calculating a first temperature difference value of indoor temperature values before and after each preset duration, determining that the absolute value of the first temperature difference value is equal to zero or is a stable time when the absolute value of the first temperature difference value falls into a preset temperature range, and determining that the indoor temperature value at the stable time is a stable temperature value;
after the primary indoor temperature value is obtained, a first temperature difference value between the indoor temperature value obtained last time and the indoor temperature value obtained currently is calculated, wherein the indoor temperature value obtained last time is 27.5 ℃, and when the secondary indoor temperature value is 29 ℃, the first temperature difference value is-1.5 ℃.
And, after determining the first temperature difference at the current moment, taking the absolute value of the first temperature difference as 1.5 ℃. And judging whether the current first temperature difference value is equal to zero or falls into a preset temperature range.
Specifically, the preset temperature range is in the range of 0 to 0.8 ℃, preferably 0 to 0.5 ℃. When the absolute value of the first temperature difference is 1.5 ℃, the absolute value does not fall within the preset temperature range. After waiting for 0.5 hour, the indoor temperature value is again acquired, and if the indoor temperature value detected again is 29.3 ℃. At this time, the first temperature difference between the temperature value 29.3 ℃ obtained again and the temperature value 29 ℃ obtained last time is-0.3 ℃, and the absolute value of the first temperature difference at the current moment is 0.3 ℃ and falls within a preset temperature range of 0 to 0.5 ℃. In this way, the current time is determined as the stable time, that is, the time at which the indoor temperature value is acquired to be 29.3 ℃ is determined as the stable time, and 29.3 ℃ is determined as the stable temperature value.
And S500, determining a second temperature difference absolute value of the set temperature value and the stable temperature value at the shutdown time of the air conditioner, determining a duration critical value according to the second temperature difference absolute value, and controlling the air conditioner to enter a power-off program when the continuous standby duration of the air conditioner exceeds the duration critical value.
After the set temperature value and the stable temperature value of the air conditioner at the shutdown time are determined, calculating that the absolute value of the temperature difference between the set temperature value and the stable temperature value at the shutdown time of the air conditioner is a second absolute value of the temperature difference, and determining a duration critical value according to the second absolute value of the temperature difference. Preferably, the greater the duration threshold, the greater the absolute value of the second temperature difference. And the standby time of the air conditioner is recorded, and the timing can be started from the time of acquiring the shutdown signal of the air conditioner or at the time of stabilizing. When the recorded standby time exceeds the time critical value, the user is judged to be no longer required to operate the air conditioner at the moment, and the air conditioner is controlled to enter a power-off program.
According to the power-off control method for the air conditioner, the set temperature value of the air conditioner at the power-off time is recorded, the stable temperature value when the indoor temperature reaches relative stability after the air conditioner is powered off is determined, the set temperature value of the air conditioner at the power-off time and the second temperature difference absolute value of the stable temperature value are determined, the time length critical value is determined according to the second temperature difference absolute value, the time length critical value is related to the set temperature value of a user and the stable temperature of the air conditioner after the air conditioner is powered off, the current demand level of the user on the air conditioner is determined through the set temperature value and the stable temperature value, different time length critical values are determined, intelligent judgment is carried out according to the actual use condition of the user, the condition of power-off in a short time is avoided, and normal use of the user is not affected; and the air conditioner can not stand by for a long time, and the intelligent automatic power-off control of the air conditioner is realized.
Specifically, in step S500 of the present embodiment, determining a second absolute value of a difference between a set temperature value at a shutdown time of the air conditioner and the stable temperature value, and determining a critical value of a duration according to the second absolute value of the difference includes:
the calculation formula of the duration critical value comprises:
t l ＝|T w -T s |×k+t 1
wherein t is l For a critical value of the duration, T w To stabilize the temperature value, T s For setting the temperature value, k is a preset coefficient, t 1 The standby time is a first preset standby time.
And determining the absolute value of the difference between the stable temperature value and the set temperature value, multiplying the absolute value of the difference by a preset system, and adding the absolute value of the difference with a first preset standby time to obtain the time critical value.
Specifically, the preset coefficient has a value in the range of 4 to 6, preferably 5; the first preset standby time length takes a value in a range from 25 hours to 35 hours, preferably 30 hours.
For example, when the set temperature at the shutdown time of the air conditioner is 23 ℃, the stable temperature value is 29.3 ℃, the absolute value of the temperature difference between the set temperature value and the stable temperature value is 6.3 ℃, the absolute value of the temperature difference is multiplied by the preset coefficient 5 to obtain 31.5, and then the 31.5 is added with the first preset standby time length 30 to obtain 61.5 hours. When the standby time exceeds 61.5 hours after the air conditioner is shut down, the air conditioner automatically enters a power-off program. When the set temperature value is 23 ℃ and the stable temperature value is 29.3 ℃, the air conditioner is indicated to be in summer with hot environment, the frequency of using the air conditioner by a user is high, after the continuous standby time of the air conditioner is judged to be longer than 61.5 hours, the possibility of using the air conditioner is judged to be low, and the power-off program is automatically entered.
Or when the set temperature at the shutdown time of the air conditioner is 23 ℃ and the stable temperature value is 26.5 ℃, the absolute value of the temperature difference between the set temperature value and the stable temperature value is 3.5 ℃, the absolute value of the temperature difference is multiplied by a preset coefficient 5 to obtain 17.5, and the 17.5 is added with the first preset standby time length 30 to obtain 47.5 hours. When the air conditioner is shut down, the standby time exceeds 47.5 hours, and the air conditioner automatically enters a power-off program. At this time, the difference between the indoor stable temperature value and the set temperature value is relatively smaller, which indicates that the possibility that the user turns on the air conditioner is relatively smaller at this time, and the corresponding duration critical value is smaller. According to the embodiment, the degree of the possibility that the user starts the air conditioner is judged by setting the difference value of the temperature value and the stable temperature value, so that the standby time of the air conditioner is combined with the current use condition of the user, and the intelligent judgment and control of the power failure of the air conditioner are realized.
Further, in the power-off control method of an air conditioner according to the present embodiment, after the power-off signal of the air conditioner is obtained, the step S500 further includes the following steps, and the steps are shown in fig. 2 in combination:
step 510, determining an operation mode of the air conditioner at the shutdown time;
step 520, judging whether the operation mode of the air conditioner at the shutdown time is a cooling mode or a heating mode:
when the operation mode of the air conditioner at the shutdown time is a refrigeration mode, judging whether the stable temperature value is smaller than or equal to the set temperature value, and if so, judging that the duration critical value is a first preset standby duration; if not, determining a second temperature difference absolute value of a set temperature value and a stable temperature value at the shutdown time of the air conditioner, and determining a duration critical value according to the second temperature difference absolute value, wherein a calculation formula of the duration critical value comprises:
t l ＝(T w -T s )×k+t 1
wherein t is l For a critical value of the duration, T w To stabilize the temperature value, T s For setting the temperature value, k is a preset coefficient, t 1 The standby time is a first preset standby time;
when the operation mode of the air conditioner at the shutdown time is a heating mode, judging whether the stable temperature value is larger than or equal to the set temperature value, and if so, judging that the duration critical value is a first preset standby duration; if not, determining a second temperature difference absolute value of a set temperature value and a stable temperature value at the shutdown time of the air conditioner, and determining a duration critical value according to the second temperature difference absolute value, wherein a calculation formula of the duration critical value comprises:
t l ＝(T s -T w )×k+t 1
wherein t is l For a critical value of the duration, T w To stabilize the temperature value, T s For setting the temperature value, k is a preset coefficient, t 1 For the first pre-preparationSetting a standby time.
It should be noted that, in the present embodiment, the operation mode of the air conditioner at the time of shutdown may be determined, and may be recorded simultaneously with the set temperature value in step S200, or may be recorded in step S300. The invention can acquire the operation mode of the air conditioner at the shutdown time after the air conditioner acquires the shutdown signal, and acquire the operation mode of the air conditioner at the shutdown time before and when the set temperature value and the stable temperature value are determined.
Further, the power-off control method of the air conditioner according to the embodiment further includes the following steps:
and during the period from the shutdown of the air conditioner to the stable time, when the startup signal of the air conditioner is received, the power-off control method of the air conditioner is exited, and the steps of the power-off control method of the air conditioner are re-executed until the shutdown signal of the air conditioner is acquired again.
Specifically, after the air conditioner acquires the shutdown signal, until the indoor temperature reaches the stable time of the stable state, when the shutdown signal of the air conditioner is received again, the air conditioner is started again when the air conditioner does not reach the stable state, the use frequency is higher, the air conditioner exits from the air conditioner power-off control method, and when the shutdown signal of the air conditioner is acquired again, the steps S100 to S500 of the air conditioner power-off control method are re-entered.
Further, when the step of executing the power-off control method of the air conditioner last time, determining that the air conditioner receives the power-on signal of the air conditioner during the period from the power-off time to the stable time, and when the continuous standby time of the air conditioner exceeds the sum of the time critical value and the second preset time in the step of executing the power-off control method of the air conditioner at the time, controlling the air conditioner to enter a power-off program.
Specifically, after the air conditioner is shut down, in the process that the indoor temperature gradually changes and reaches a stable temperature value, the air conditioner receives a starting signal, and at the moment, the power-off control of the air conditioner is stopped. And after the air conditioner receives the air conditioner shutdown signal again, the air conditioner executes the steps of the air conditioner power-off control method again, after the stable temperature value and the set temperature value are determined, the continuous standby time of the air conditioner is recorded, and when the continuous standby time of the air conditioner exceeds the sum of the time critical value and the second preset time, the air conditioner is controlled to enter a power-off program.
Specifically, the second preset time period is in the range of 21 to 27 hours, preferably 24 hours. When the set temperature at the closing time of the air conditioner is 23 ℃ and the stable temperature value is 26.5 ℃, the absolute value of the temperature difference between the set temperature value and the stable temperature value is 3.5 ℃, the absolute value of the temperature difference is multiplied by a preset coefficient 5 to obtain 17.5, and the 17.5 is added with the first preset standby time length 30 to obtain the time length critical value of 47.5 hours. However, since the user turns on the air conditioner again after the last time the air conditioner was turned off and in the process of reaching the stable time, it means that the frequency of the use of the air conditioner by the user is high, and the time of adding 24 hours to the time of calculating 47.5 hours is 71.5 hours.
