Fig. 1 is an environmental condition control method according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, acquiring temperature information and humidity information in a preset space;
step S104, determining whether the humidity information meets a first preset condition;
and step S106, under the condition that the humidity information does not meet the first preset condition, controlling the work of the humidifying structure according to the temperature information so as to adjust the humidity in the preset space.
The environmental condition control method adopting the scheme comprises the following steps: acquiring temperature information and humidity information in a preset space; determining whether the humidity information meets a first predetermined condition; and under the condition that the humidity information does not meet the first preset condition, controlling the work of the humidifying structure according to the temperature information so as to adjust the humidity in the preset space.
The applicant finds that when the humidifying structure is used in different temperature environments, the humidifying effect is different, the higher the environment temperature is, the easier the humidifying structure is to humidify, the lower the environment temperature is, the harder the humidifying structure is to realize humidification, the existing humidifying control method only controls the work of the humidifying structure according to the humidity, and the existing humidifying control method is easily influenced by the environment temperature to cause the poor humidifying effect and cause the over-slow humidifying or over-humidifying condition.
Like this, when humidity information is not conform to first predetermined condition, humidity in the predetermined space unsatisfied requirement promptly, control the work of humidification structure according to temperature information, can make the humidification structure adapt to with ambient temperature more accurately, avoid influencing the humidification effect of humidification structure because ambient temperature's fluctuation, improve humidification control accuracy.
Specifically, the humidity information includes a current humidity and a target humidity, and determining whether the humidity information meets a first predetermined condition includes: if the duration that the current humidity is greater than the target humidity is greater than or equal to a first preset duration, determining that the humidity information meets a first preset condition; and if the current humidity is less than or equal to the target humidity, or the duration that the current humidity is greater than the target humidity is less than a first preset duration, determining that the humidity information does not conform to a first preset condition.
That is, if the current humidity is always greater than the target humidity within the first preset time period, it indicates that the current humidity can be stably maintained at the target humidity, and this indicates that the ambient humidity has reached the standard. On the contrary, if the current humidity is less than or equal to the target humidity, or the duration that the current humidity is greater than the target humidity cannot be maintained for the first preset duration, it indicates that the current humidity cannot be stably maintained at the target humidity, and at this time, it indicates that the ambient humidity does not reach the standard, and it is necessary to control the operation of the humidifying structure according to the temperature information, so as to implement accurate humidification control on the surrounding environment.
In the embodiment, if the current humidity can be maintained to be higher than the target humidity within Z minutes, the humidity information is determined to meet a first preset condition; otherwise, it is determined that the humidity information does not comply with the first predetermined condition.
Specifically, the temperature information includes a target temperature and a current temperature, the humidifying structure includes a humidifying valve, and the operation of the humidifying structure is controlled according to the temperature information, including: determining a target opening value under the condition that the difference value between the target temperature and the current temperature meets a second preset condition, wherein the target opening value is the opening value of the humidifying valve corresponding to the target temperature; and controlling the humidifying valve to work at the target opening value.
When the difference value between the target temperature and the current temperature meets a second preset condition, the target opening value of the humidifying valve is determined by the target temperature, so that the control logic can be effectively simplified, and the realization of the environmental condition control method is facilitated.
Specifically, in a case where a difference between the target temperature and the current temperature meets a second predetermined condition, determining a target opening value, which is an opening value of the humidification valve corresponding to the target temperature, includes: matching the target temperature with a plurality of preset temperature ranges; determining one preset opening value in a plurality of preset opening values as a target opening value according to the matching result of the target temperature and a plurality of preset temperature ranges; the temperature ranges and the opening values are in one-to-one mapping relation; the smaller the minimum temperature value in the plurality of preset temperature ranges is, the larger the corresponding preset opening value is.
That is to say, the preset temperature ranges correspond to the preset opening values one to one, and under the condition that the difference value between the target temperature and the current temperature meets the second preset condition, the preset opening value corresponding to the preset temperature range is determined to be the target opening value according to which preset temperature range the target temperature is located, so that the opening control frequency of the humidifying valve can be reduced on the basis of ensuring that the humidifying valve adjusts the opening according to the temperature information, the control logic is effectively simplified, and the service life of the humidifying valve is prolonged. Moreover, the smaller the minimum temperature value in the plurality of preset temperature ranges is, the larger the preset opening value corresponding to the minimum temperature value is, that is, the lower the target temperature is, the larger the preset opening value corresponding to the minimum temperature value is, so that the humidification speed in the low-temperature environment can be increased, and the problem of excessive humidification in the high-temperature environment can be avoided.
Specifically, in the case that the difference between the target temperature and the current temperature meets the second predetermined condition, before determining the target opening value, controlling the operation of the humidifying structure according to the temperature information further includes: determining one preset reference value in a plurality of preset reference values as a target reference value according to the matching result of the target temperature and a plurality of preset temperature ranges; when the difference value between the target temperature and the current temperature is smaller than or equal to the target reference value, determining that the difference value between the target temperature and the current temperature meets a second preset condition; the preset temperature ranges and the target reference values are in one-to-one mapping relation; the larger the maximum temperature value in the plurality of preset temperature ranges is, the larger the preset reference value corresponding thereto is.
That is, the higher the preset temperature range of the target temperature match, the larger the preset reference value is, that is, under the condition that the target temperature is higher, the larger the temperature range of controlling the opening of the humidification valve by using the corresponding target opening value is, that is, when the target temperature is higher, even if the difference between the target temperature and the current temperature is larger, the target opening value corresponding to the target temperature can be used to control the humidification valve; when the target temperature range is low, the difference between the target temperature and the current temperature needs to be small, so that the target opening value corresponding to the target temperature can be used for controlling the humidifying valve. Through the sectional control realized by combining the environmental temperature, the control of the humidifying valve can be accurately realized, and the humidifying accuracy is ensured.
Specifically, the temperature information includes a target temperature and a current temperature, and controls the operation of the humidification structure according to the temperature information, further including: and if the difference value between the target temperature and the current temperature is less than or equal to a first preset value and the target temperature is greater than or equal to a second preset value, controlling the humidifying valve of the humidifying structure to work according to preset control logic.
That is, when the target temperature is greater than the second preset value, it indicates that the target temperature is sufficiently large, at which time the influence of the temperature change on the humidification effect becomes small. If the current temperature is within the range close to the target temperature, namely the difference value between the target temperature and the current temperature is less than or equal to a first preset value, the work of the humidifying valve can be controlled according to a preset control logic, so that the realization of an environmental condition control method is facilitated, and the flexibility of humidifying control is improved. The preset control logic may select various control logics, such as PI, PD, PID, etc., according to actual needs, and in this embodiment, the preset control logic is a PID control logic.
In the embodiment, if the target temperature-the current temperature is less than or equal to Δ t1 and the target temperature is greater than or equal to a ℃, the humidifying valve is controlled to automatically adjust through PID control logic; if the target temperature-the current temperature is less than or equal to delta t2 and the target temperature B is less than or equal to A ℃, locking the opening a% of the humidifying valve until the current humidity is greater than the target humidity for Z minutes; if the target temperature-the current temperature is less than or equal to delta t3 and the target temperature is less than or equal to C and less than B ℃, locking the opening B% of the humidifying valve until the current humidity is greater than the target humidity for Z minutes; and if the target temperature-the current temperature is less than or equal to delta t4 and the target temperature D is less than or equal to C ℃, locking the opening C% of the humidifying valve until the humidity lasts for Z minutes and is greater than the target humidity.
When the temperature is higher, the humidity adjustment is easier, and only the humidifying valve is needed to perform automatic adjustment. The humidification difficulty is increased along with the gradual reduction of the target temperature, sectional control is needed, and the difference between the target temperature and the current temperature needs to be judged under different target temperatures, wherein a > B > C > D, C > B > a, Δ t1 >. delta t2 >. delta t3 >. delta t4, in the embodiment, a is 5, B is 0, C is-10, D is-25, a is 3, B is 4, C is 5, Δ t1 is 3, Δ t2 is 2.5, Δ t3 is 2, and Δ t4 is 1.5.
Specifically, the humidity information includes a current humidity and a target humidity, and the environmental condition control method further includes: determining whether the difference value between the target humidity and the current humidity is smaller than a third preset value or not under the condition that the humidity information meets a first preset condition; and if the difference value between the target humidity and the current humidity is greater than or equal to a third preset value, acquiring the average opening value of the humidifying valve of the humidifying structure in the target time period, and controlling the humidifying valve to work for a second preset time length at the average opening value.
And if the absolute value of the difference value between the target humidity and the current humidity is smaller than a third preset value, controlling the humidifying structure to operate in the current state.
Specifically, after controlling the humidification valve to operate at the average opening value for a second preset period of time, the environmental condition control method further includes: determining whether the difference value between the target humidity and the current humidity is smaller than a third preset value; and if the difference value between the target humidity and the current humidity is greater than or equal to a third preset value, controlling the opening of the humidifying valve to continuously increase according to a first preset rate until the difference value between the target humidity and the current humidity is less than the third preset value.
That is, after the humidifying valve is controlled to operate at the average opening value for the second preset time, if the difference between the target humidity and the current humidity is still greater than or equal to the third preset value, the opening of the humidifying valve is controlled to continuously increase according to the first preset rate, so that the current humidity can be controlled to be smoothly adjusted to be close to the target humidity, and the humidifying control effect is ensured.
In this embodiment, if the current humidity can be maintained to be greater than the target humidity within Z minutes, it is determined whether the target humidity — the current humidity is less than F%, and if so, the current opening of the humidifying valve is maintained; if not, continuously detecting the opening of the humidifying valve in W minutes, calculating the average opening value of the humidifying valve to be (the highest output-the lowest output)/2, controlling the humidifying valve to keep working for E minutes at the average opening value, then judging whether the target humidity-the current humidity is smaller than F%, if so, maintaining the opening of the current humidifying valve, and if not, controlling the opening of the humidifying valve to increase R% per minute until the target humidity-the current humidity is smaller than F%. Preferably, R is 0.5 and F is 3. In order to ensure the stability of the humidifying operation and reduce the humidifying fluctuation, the maximum opening degree of the humidifying valve is not more than 3 a%, wherein a% is the opening degree of the humidifying valve when the detected target temperature-the current temperature is not more than delta t2, and the target temperature B is not more than B and is not more than A ℃.
Specifically, the temperature information includes a target temperature and a current temperature, and the environmental condition control method further includes: determining whether the target temperature is greater than a first preset temperature under the condition that no requirement is made on the environmental humidity in the preset space; if the target temperature is higher than the first preset temperature, controlling a humidifying valve of the humidifying structure to be closed; and if the target temperature is less than or equal to the first preset temperature, controlling the humidifying valve to work at a first preset opening degree.
In this way, when the target temperature is higher than the first preset temperature, the humidifying valve of the humidifying structure is controlled to be closed, and when the target temperature is lower than or equal to the first preset temperature, the humidifying valve is controlled to work at the first preset opening degree. When the humidification structure is specifically implemented, the value of the first preset temperature and the value of the first preset opening degree can be flexibly selected, so that the humidification valve of the humidification structure maintains the operation of the first preset opening degree at low temperature, the condition that the humidification valve is frozen can be avoided, and the service life of the humidification structure is ensured. In this embodiment, the first preset temperature is 5 ℃ and the first preset opening is 1%, i.e. 1% of the maximum opening.
Specifically, the temperature information includes a target temperature and a current temperature, and the environmental condition control method includes: calculating the difference between the target temperature and the current temperature to obtain a temperature difference value; under the condition that the temperature difference value falls into a first preset temperature difference range, determining whether the change rate of the current temperature is smaller than a second preset rate or not; and if the change rate of the current temperature is greater than or equal to a second preset rate, controlling and adjusting the working state of the temperature regulating equipment to enable the change rate of the current temperature to be smaller than the second preset rate.
Specifically, the temperature information includes a target temperature and a current temperature, and the environmental condition control method includes: calculating the difference between the target temperature and the current temperature to obtain a temperature difference value; matching the temperature difference value with a plurality of preset ranges; determining one preset working mode in multiple preset working modes as a target working mode according to the matching result of the temperature difference value and multiple preset ranges; controlling the temperature regulating equipment to operate in a target working mode; the preset ranges and the preset working modes are in one-to-one mapping relation.
Specifically, the preset operating mode may be flexibly set according to actual conditions, and in a specific embodiment, the environmental condition control method includes: judging the relation between the target temperature and the current temperature, and entering a temperature rise control mode if the target temperature is more than or equal to the current temperature; and if the current temperature is higher than the target temperature, entering a temperature drop control mode.
In the temperature rise control mode, if the target temperature-the current temperature is more than or equal to T1 ℃, the fixed electric heating is started, the adjustable electric heating output is locked at S1%, and the refrigerator 1 (minimum load) is started. If the temperature T1 ℃ is not less than the target temperature and the current temperature is not less than T2 ℃, the fixed electric heating is started, the adjustable electric heating locking output S2 percent is output, and the refrigerator 1 (minimum load) is kept started.
