The indoor environmental parameters are closely related to the external environment, and the indoor environmental parameters are often adjusted by various environmental controllers, such as: water curtain wall, heating machine, exhaust fan, transom, canvas, air conditioner, etc. To ensure that the environmental conditions can be maintained within the appropriate range, and the environmental parameters affected by these environmental controllers are also different, and even one environmental controller affects several environmental parameters at the same time. Therefore, when the outdoor environment changes with day and night and four seasons If the environmental controllers are adjusted in real time as the outdoor environment changes and only one environmental parameter is considered, it may not be possible to smoothly regulate these environmental parameters within the suitable range for the growth of various organisms.

Detailed ways

Based on the above-mentioned technical features, the main functions of the multivariable environment regulation method of the present invention will be clearly presented in the following examples.

Referring to FIG. 1 and FIG. 2 , an embodiment of the multivariable environment regulation method of the present invention is executed by a control system. The control system includes a processor 1 , a multivariable database 2 , an environmental control device 3 , and a plurality of indoor environmental parameter sensors 4 . The multivariate environment control method includes a step S01 of establishing a multivariate database, a first data collection step S02, a second data collection step S03, a judgment step S04, a comparison execution step S05, and a continuation execution step S06.

The control system is set in an indoor space. The processor 1 is connected with the multivariate database 2 , the environment control device 3 , and the indoor environment parameter sensors 4 in signal connection. The environmental control device 3 includes a variety of environmental controllers 31, and the environmental controllers 31 are respectively a water curtain wall, a heating machine, an exhaust fan, a transom window, a canvas, and an air conditioner. In this example, the number of each type of environmental controller 31 is taken as one for illustration. In this example, the number of the indoor environment parameter sensors 4 is three, and they respectively sense a plurality of environmental parameters of the indoor space, and the environmental parameters are respectively a temperature, a humidity and a carbon dioxide concentration. Each environmental controller 31 affects at least one environmental parameter. Please refer to Table 2.

Table II

environmental controller Environmental parameters water curtain wall Lower temperature, higher humidity, lower carbon dioxide concentration heating machine Increased temperature, decreased humidity, increased carbon dioxide concentration exhaust fan Lower temperature, lower humidity, lower carbon dioxide concentration transom lower carbon dioxide concentration canvas temperature increase air conditioner lower temperature, lower humidity

The step S01 of establishing a multivariate database is to establish the multivariate database 2 in advance. The multi-variable database 2 stores multiple combinations of environmental parameter value ranges before regulation, multiple environmental control modes, and multiple target value range combinations in a closed space. Preferably, the enclosed space has the same size as the indoor space. The multivariate database 2 is established according to an environmental change factor, and the environmental change factor includes at least one of a sunlight exposure factor and a seasonal change factor. For example, the multivariate database 2 can be established according to day and night, or according to four seasons of spring, summer, autumn and winter. Even, the multivariate database 2 can be established according to morning and evening and four seasons. For example, if the multivariate database 2 is to be used in summer nights, it is established according to the environmental conditions in summer nights.

In the multivariate database 2 , each combination of value ranges of environmental parameters before regulation includes multiple value ranges of different environmental parameters before regulation. The pre-regulation environmental parameters are the same as the environmental parameters. Each target value range combination includes multiple value ranges of different regulated environmental parameters. The pre-regulation environmental parameters are the same as the post-regulation environmental parameters. Each combination of environmental parameter value ranges before regulation corresponds to one of the environmental control modes and one of the target value range combinations. Therefore, for each combination of environmental parameter value ranges before adjustment, the environmental control device 3 implements the corresponding environmental control mode, so that the value range of the environmental parameters before adjustment in the closed space tends to be closer to the environment after adjustment. The range of values for the parameter. The value ranges of the regulated environmental parameters are the environmental conditions suitable for growth of an organism in a certain period of time. In addition, the environmental control mode corresponding to each combination of environmental parameter value ranges before regulation is based on the value range of the environmental parameters before regulation outdoors, the effect of the environmental control device 3 on the environmental parameters before regulation, the enclosed space The value range of the environmental parameters before regulation, the corresponding target value range combination, and the size setting of the enclosed space. Wherein, the environmental control mode is set according to the value range of the outdoor environmental parameters before regulation because the environmental control device 3 will introduce outdoor air during operation, so it is necessary to refer to the value range of the outdoor environmental parameters before regulation . For example, in summer and winter, the indoor temperature must be maintained at 20 degrees. The environmental control modes set by the two, such as the air volume and temperature of the air conditioner, must be different. If you look at it in a day, the air conditioner settings for the day and night The patterns will also be slightly different. The setting of the environmental control mode is also based on the respective effects of the environmental controllers 31 of the environmental control device 3 on the environmental parameters before regulation, please refer to Table 2 for example. The environmental parameters that the operation of the water curtain wall will affect are to lower the temperature, increase the humidity, and reduce the carbon dioxide concentration, and the environmental parameters that will be affected by the operation of the heating machine are to increase the temperature, the Humidity decreases, the carbon dioxide concentration increases, the environmental parameters that the operation of the exhaust fan will affect are to reduce the temperature, the humidity, and the carbon dioxide concentration, and the opening of the transom will affect the environmental parameters. The carbon dioxide concentration decreases, the environmental parameters affected by the covering of the canvas are to increase the temperature, and the environmental parameters affected by the operation of the air conditioner are to reduce the temperature and humidity.

Each target value range combination is related to the number of each environmental controller 31 that is set to be executed in the corresponding environmental control mode. The number of each environmental controller 31 is activated, and the environmental benefits are significantly different. Therefore, the number of activations of each environmental controller 31 is closely related to the performance of environmental benefits, changes in the outdoor environment, and environmental factors required for the growth of various organisms.

In the multivariate database 2, the value range of each pre-regulation environmental parameter value range of each pre-regulation environmental parameter value range combination presets a preset range, and the value range of each pre-regulation environmental parameter is higher than the One of the preset range, within the preset range and below the preset range, when the number of such pre-regulation environmental parameters in each combination of pre-regulation environmental parameter value ranges is n, due to any pre-regulation environment The value range of the parameter has three different ranges, so that the number of combinations of the environmental parameter value ranges before regulation is 3n, and the number of the target value range combinations is also 3n, and the combinations of the environmental parameter value ranges before regulation correspond to the and other target value range combinations. For the convenience of description below, the value range of each environmental parameter before regulation is expressed as a high level when it is higher than the preset range, and the value range of each environmental parameter before regulation is expressed as a middle level within the preset range , the value range of each environmental parameter before regulation is lower than the preset range, which is represented as a low level. It should be added that the combination of environmental parameter value ranges before regulation sometimes cannot be directly adjusted to the corresponding target value range combination, and may first tend to a combination of environmental parameter value ranges in regulation, and then use the environment control device 3 After a corresponding intermediate environmental control mode is adjusted, let the combination of environmental parameter value ranges in regulation tend towards the corresponding target value range combination, wherein the combination of environmental parameter value ranges in regulation includes multiple values of environmental parameters in different regulation range, the environmental parameters in the regulation are the same as the environmental parameters before the regulation, therefore, the multivariable database 2 also stores the value range combination of the environmental parameters in the regulation and the intermediate environment control mode, the value range combination of the environmental parameters in the regulation is It should be a combination of the intermediate environmental control mode and one of the pre-regulation environmental parameter value ranges. Or, the pre-regulation environmental parameter value range combinations will first tend to the corresponding environmental parameter value range combinations during the regulation, and then tend to the corresponding target value range combinations after being adjusted by the corresponding intermediate environmental control modes. Therefore, the multivariate database 2 also stores the value range combinations of the environmental parameters during regulation and the corresponding intermediate environmental control modes, wherein a combination of environmental parameter value ranges during regulation corresponds to one of the intermediate environmental control modes and one of the pre-regulation environment Combination of parameter value ranges.

For example, Table 3 shows the multivariate database 2 of a white broiler chicken, the environmental parameters before regulation are the temperature, the humidity and the carbon dioxide concentration, the range combination of environmental parameters before regulation and the target values The number of range combinations is 27, and there are 27 states. Among them, there are only four types of states in the 27 combinations of target value ranges, and these four types of states are the environmental states suitable for the growth of the white meat chicken: one of the states is that the temperature is in the middle level, the humidity is in the middle level, The carbon dioxide concentration is at the middle level; another state is that the temperature is at the middle level, the humidity is at the middle level, and the carbon dioxide concentration is at the low level; yet another state is that the temperature is at the middle level, The humidity is at the low level, the carbon dioxide concentration is at the middle level; yet another state is that the temperature is at the middle level, the humidity is at the low level, and the carbon dioxide concentration is at the low level. Each of these combinations of environmental parameter value ranges before regulation will eventually tend to the state of any type of target value range combination, wherein states 2, 3, 5, 6, 8, and 9 will first tend to these combinations of environmental parameter value ranges in regulation, and then After being adjusted by the corresponding intermediate environmental control modes respectively, they tend to the combinations of target value ranges. It should be added that the states of target value range combinations suitable for growth of each organism are different, and the number of states presenting different states is also different. The number of target value range combinations must be set to be the same as the number of environmental parameter value range combinations before regulation.

Table three

The first data collection step S02 is to use the indoor environmental parameter sensors 4 to continuously sense the environmental parameters, and then use the processor 1 to continuously obtain a first preset time interval from the indoor environmental parameter sensors 4 A combination of environmental parameter value ranges, the first environmental parameter value range combination is the value range of these environmental parameters in the indoor space where the environmental control device 3 operates in a first environmental control mode. For example, the first preset time interval is the time interval from 8:00 am to 9:00 am, and the first environmental control mode is to run the heating machine, open the air window, and run the air conditioner.

The second data collection step S03 is to use the processor 1 to continuously obtain a second environmental parameter value range combination from the indoor environmental parameter sensors 4 in a second preset time interval before the first preset time interval, the The second environmental parameter value range combination refers to the value ranges of the environmental parameters in the indoor space. It should be noted that during the second preset time interval, the operating mode of the environmental control device 3 is not limited. For example, the second preset time interval is the time interval from 7:00 am to 8:00 am.

The judging step S04 is to use the processor 1 to continuously compare the first environmental parameter value range combination and the second environmental parameter value range combination, and determine whether the first environmental parameter value range combination is compared with the second environmental parameter value parameter value. Whether the range combination is approaching any target value range combination. If the processor 1 judges that the first environmental parameter value range combination is not approaching any target value range combination compared with the second environmental parameter value range combination, perform the comparison and execute step S05, if the processor 1 judges If the first environmental parameter value range combination is closer to any target value range combination than the second environmental parameter value range combination, the step S06 is continued. The detailed method is to use the processor 1 to compare a maximum value, a minimum value, an average value and a standard deviation in the value range of each environmental parameter in the first environmental parameter value range combination with the second Comparing a maximum value, a minimum value, an average value and a standard deviation in the value range of each environmental parameter in the environmental parameter value range combination, to determine whether the first environmental parameter value range combination is better than the second environmental parameter value range combination Whether the environmental parameter value range combination is approaching any target value range combination. For example, the first environmental parameter value range combination measured in the time interval from 8:00 to 9:00 am is compared with the second environmental parameter value range combination measured in the time interval from 7:00 to 8:00 am. Compared with the second environmental parameter value range combination, whether the first environmental parameter value range combination is approaching the target value range combination in any of the aforementioned four types of states, if yes, it indicates that the operation of the first environmental control mode is If it is suitable, the step S06 needs to be continued, otherwise, it means that the operation of the first environmental control mode is not suitable, then the comparison needs to be performed and the step S05 is executed.

The comparison execution step S05 is to use the processor 1 to compare the first environmental parameter value range combination with the pre-regulation environmental parameter value range combination in the multivariate database 2, and according to the pre-regulation environment that matches the comparison The parameter value ranges are combined to control the environment control device 3 to operate in the corresponding environment control mode. For example, the combination of the environmental parameter value ranges of the first environmental parameter value range combination is that the temperature is the low level, the humidity is the low level, and the carbon dioxide concentration is the middle level, corresponding to the state of the multivariate database 2. It is the same as the combination of the pre-regulation environmental parameter value ranges in state 2, the processor 1 controls the environmental control device 3 to operate in the corresponding environmental control mode, and the value ranges of the environmental parameters tend to correspond to the control Combination of environmental parameter value ranges, then the processor 1 controls the environmental control device 3 to operate in the corresponding intermediate environmental control mode, so that the value ranges of the environmental parameters tend to the corresponding target value range combination, which is the temperature The middle level, the low humidity, and the middle level of carbon dioxide concentration achieve a suitable feeding environment for the white meat chicken. Return to the first data collection step S02 after executing the comparison execution step S05.

The continuing step S06 is to use the processor 1 to control the environment control device 3 to continue to operate in the first environment control mode. Return to the first data collection step S02 after executing the continuing step S06.

Therefore, in this example, the processor 1 continuously collects the value ranges of the environmental parameters in various time intervals, and compares them with the time intervals at the previous point in time to determine whether the value ranges of the environmental parameters are heading toward Any combination of target value ranges is approaching, otherwise, the environmental control device 3 is regulated according to the multivariate database 2, so that the value ranges of the environmental parameters of the indoor space are approaching any combination of target value ranges, so as to achieve the maximum good control mechanism.

To sum up, through the step S01 of establishing a multivariate database, through long-term data accumulation, the combination of environmental parameter value ranges before regulation, the corresponding environmental control modes, and the corresponding target values are established and stored in advance. The multi-variable database 2 of range combination, and then through the first data collection step S02, the second data collection step S03 and the judgment step S04, use the processor 1 to continuously judge the current first environmental parameter of the indoor space Whether the combination of value ranges is suitable for the environmental state of the creature, if not, the comparison is performed and step S05 is performed, and the processor 1 is used to perform the environmental control that meets the combination of value ranges of the first environmental parameter according to the comparison of the multivariate database 2 Mode, to adjust the value range of these environmental parameters to reach any combination of target value ranges, if it is suitable, proceed to the step S06, continue to operate in the first environmental control mode, and continue to judge the value by the processor 1 Whether the current combination of the first environmental parameter value ranges in the indoor space is suitable for the environmental state of the creature, so as to achieve a control mechanism that considers multiple environmental parameters and maintains the indoor space at an optimal level.
