when the fact that the actual temperature value in the drying room is lower than the first threshold temperature is detected, controlling each heater 100 to output the maximum power;

when the fact that the actual temperature value in the drying room is larger than the first threshold temperature and smaller than the second threshold temperature is detected, the power of the heater 100 is gradually increased;

when the actual temperature value is greater than the target temperature value, the step S421 of reducing the heating power of the heater 100 includes:

when the fact that the actual temperature value in the drying room is larger than the third threshold temperature and smaller than the fourth threshold temperature is detected, the heating power of the heater 100 is reduced step by step;

when the actual temperature value in the drying room is detected to be greater than the fourth threshold temperature, the heating power of the heater 100 is rapidly reduced.

In this embodiment, the specific implementation process of the method steps can refer to the detailed description in the system embodiment, which is not described herein again. In a specific application scenario of drying and disinfecting in a farm, as shown in fig. 6, the first threshold temperature may be set as: t1 ═ 60 ℃, the second threshold temperature may be set as: t2 ═ 65 ℃, the third threshold temperature may be set as: t3 ═ 66 ℃, the fourth threshold temperature may be set as: t4 ═ 68 ℃. Depending on the number of on-times of the heater 100, five heating power levels may be set: grade one: the four groups of heaters do not work; grade two: starting the heater group 1; grade three: simultaneously starting the heater groups 1 and 2; grade four: simultaneously starting the heater groups 1, 2 and 3; grade five: the

heater groups

1, 2, 3, 4 are switched on simultaneously. In the drying control process, when the actual temperature value in the drying room is detected to be lower than the first threshold temperature, namely lower than T1 (namely 60 ℃), the heating level 5 is controlled to be started in a quick delay mode, and the maximum heating power is output to the drying room, so that the temperature is raised quickly.

When the actual temperature value in the drying room is detected to be greater than the first threshold temperature and less than the second threshold temperature, namely the temperature is within the range of T1-T2 (60-65 ℃), the heating grade is increased step by step in a delayed manner until the temperature in the room reaches 65 ℃.

And when the actual temperature value in the drying room is detected to be greater than the second threshold temperature and less than the third threshold temperature, namely the temperature is within T2-T3 (65-66 ℃), keeping the current heating level.

And when the actual temperature value in the drying room is detected to be greater than the third threshold temperature and less than the fourth threshold temperature, namely the temperature is within T3-T4, the heating grade is reduced step by step in a delayed manner until the temperature in the room returns to T2-T3. When the indoor temperature is higher than T4, i.e. the actual temperature >68 ℃, the heating level drop level drops. For example, currently level three, directly down to level one.

In one embodiment, as shown in fig. 6, the farm drying and sterilizing control method further includes the steps of:

when the actual temperature value is lower than the low-temperature alarm temperature, an alarm signal is output, the alarm signal is used for driving an alarm to execute alarm action and/or,

when the actual temperature value is lower than the low-temperature alarm temperature, the current accumulated disinfection time is reset, and the maximum power heating is restarted to ensure the virus inactivation.

The low temperature alarm temperature may be set according to a specific application scenario, for example, the low temperature alarm temperature Tmin may be set to 56 ℃. When the indoor grade is lower than the low-temperature alarm temperature Tmax, clearing the current accumulated disinfection time to ensure the disinfection effect, directly starting the heating grade to the fifth grade, outputting an alarm signal, and driving an alarm to give an alarm, wherein the alarm can be an audible and visual alarm.

when the actual temperature value is detected to be higher than the high-temperature alarm temperature, an alarm signal is output and used for driving an alarm to execute an alarm action; and/or the presence of a gas in the gas,

when the actual temperature value is detected to be higher than the high-temperature alarm temperature, the heating power of the heater is quickly reduced.

The high-temperature alarm temperature may be set according to a specific application scenario, for example, the high-temperature alarm temperature Tmax may be set to 72 ℃. When the indoor level is higher than the high-temperature alarm temperature Tmax, the heating level can be directly reduced to level one, an alarm signal is output, the alarm is driven to alarm, and the alarm can be an audible and visual alarm.

In one embodiment, as shown in fig. 5 to 6, the farm drying and sterilizing control method further includes the steps of:

s60: and controlling the working time of the heater 100 according to the target temperature interval of the actual temperature in the drying room and the continuous working time of each target temperature interval, wherein each target temperature value is in each target temperature interval in a one-to-one correspondence manner.

Because under the different stoving temperature environment, in order to carry out abundant disinfection to the object in the stoving room, need set up different stoving disinfection duration. Specifically, two target temperature intervals may be set: first target temperature interval: 56-60 ℃, and the working time of heating and drying is 70 minutes in the temperature range; second target temperature interval: and at the temperature of 60-72 ℃, the heating and drying working time is 30 minutes. And when the actual temperature is continuously changed in the first temperature interval and the second temperature interval during drying and heating, the total time Ts when the actual temperature of the drying room falls into the first temperature interval is automatically accumulated (because the whole process may occur for many times), and the heating working time is prolonged to 0.57Ts after the system works for 30 minutes because the inactivation is carried out for 70 minutes at 56-60 ℃.

The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
