It can be seen from Tables 1 and 2 that the environmental parameters required by various organisms in each growth period are different. The indoor environmental parameters are closely related to the external environment, and the indoor environmental parameters are often adjusted by many environmental control devices, such as fans, water walls, heaters, air conditioners, etc., to ensure that the environmental conditions can be maintained within a suitable range. , but the outdoor environment changes drastically with day and night and the four seasons. Adjusting the environmental control equipment in real time with the change of the outdoor environment may not be able to smoothly adjust the environmental parameters in the suitable range for the growth of various organisms. Therefore, the indoor environmental control It has been a research direction in this field that the equipment can coordinate with the external environment to adjust the indoor environmental parameters in the suitable range for biological growth.

Therefore, in order to enable the indoor environmental control equipment to coordinate with the external environment to adjust the environmental parameters within the suitable range for biological growth, the present inventor proposes a method and a basis for adjusting the control mode of the environmental control equipment in the enclosed space according to the outdoor environmental parameters. A comparison database method for establishing control modes of environmental control equipment in enclosed spaces based on outdoor environmental parameters.

The method for adjusting a control mode of an environmental control device in an enclosed space according to an outdoor environment parameter includes a step of establishing a comparison database, a step of comparison, and a step of execution.

The step of establishing a comparison database is to establish a comparison database in advance. The comparison database stores a plurality of reference outdoor environment parameter ranges, and a plurality of environmental control modes corresponding to an environmental control device. An internal environment parameter range required for maintaining an enclosed space, the comparison step is that the processor obtains an outdoor environment parameter to be adapted to, and compares the to-be-adapted outdoor environment parameter with the above-mentioned reference outdoor environment parameter range, and the execution step is as follows: The processor controls the environmental control device to operate in the corresponding environmental control mode according to the matched reference outdoor environment parameter range.

Further, the establishment of each reference outdoor environment parameter range is based on obtaining a plurality of interior detection environment parameters of the enclosed space in the environment control mode under a preset time; when the average of the interior detection environment parameters is obtained When the value conforms to the range of the internal environmental parameters, obtain a plurality of known outdoor environmental parameters at the preset time; when the standard deviation of the internally detected environmental parameters is less than the standard deviation of the known outdoor environmental parameters, and when the When the order distribution of the known outdoor environment parameters exhibits a Gaussian distribution, record the known outdoor environment parameters as the reference outdoor environment parameter range.

Further, the order distribution of the known outdoor environment parameters presents the Gaussian distribution, and when a high point of the Gaussian distribution is at a center of the Gaussian distribution, record the known outdoor environment parameters as the reference outdoor environment parameter range .

Further, when the to-be-adapted outdoor environment parameter falls within a plurality of the reference outdoor environment parameter ranges, the processor compares the to-be-adapted outdoor environment parameter with a respective central value of the reference outdoor environment parameter ranges, and the processor The environmental control device is controlled to operate in the corresponding environmental control mode according to the reference outdoor environmental parameter range of the central value of the outdoor environmental parameter to be adapted.

Further, the preset time is classified according to an environment change factor, and the environment change factor includes at least one of a factor of whether or not sunlight is illuminated and a factor of seasonal change.

Further, when the frequency distribution of the known outdoor environment parameters exhibits the Gaussian distribution, the known outdoor environment parameters appearing more than a predetermined number of times in the Gaussian distribution are extracted and recorded as the reference outdoor environment parameter range.

Further, the known outdoor environment parameters are sampled at intervals of an environmental parameter interval, and the number of occurrences of the known outdoor environment parameters in each sampling category after sampling is counted to obtain the number of times the known outdoor environment parameters distributed.

Further, when the average value of the internally detected environmental parameters does not conform to the range of the internal environmental parameters, or when the standard deviation of the internally detected environmental parameters is not less than the standard deviation of the known outdoor environmental parameters, or when the When it is known that the frequency distribution of the outdoor environment parameter does not show the Gaussian distribution, the environment control mode corresponding to the environment control device is adjusted, and the updated reference outdoor environment parameter range of the environment control mode is re-established.

Further, when the high point of the Gaussian distribution is not at the center of the Gaussian distribution, adjust the environment control mode corresponding to the environment control device, and re-establish the updated reference outdoor environment parameter range of the environment control mode.

The method for establishing a comparison database for the control mode of an environmental control device in an enclosed space according to outdoor environment parameters includes an internal data collection step, an external data collection step, and a storage step.

The internal data collection step is to obtain a plurality of internally detected environmental parameters in a closed space under an environment control mode at a preset time, and the external data collection step is when the average value of the internally detected environmental parameters conforms to a When the range of the internal environmental parameters is within the range, obtaining a plurality of known outdoor environmental parameters at the preset time, and the storing step is when the standard deviation of the internally detected environmental parameters is less than the standard deviation of the known outdoor environmental parameters, and when When the frequency distribution of the known outdoor environment parameters exhibits a Gaussian distribution, the known outdoor environment parameters are recorded as a reference outdoor environment parameter range.

According to the above technical features, the following effects can be achieved:

1. By accumulating data over a long period of time, different sets of the reference outdoor environment parameter ranges and the corresponding multiple sets of the environmental control modes are established in advance. As long as the parameters to be adapted to the outdoor environment are obtained in advance, they can be compared. The appropriate environmental control mode in the comparison database is implemented accordingly. If the outdoor environment parameters to be adapted are not within the scope of the comparison database, the administrator can manually or remotely control the operation of the environmental control equipment to respond to The advent of severe weather.

2. The processor determines that the average value of the internally detected environmental parameters conforms to the range of the internal environmental parameters, and the standard deviation of the internally detected environmental parameters is less than the standard deviation of the known outdoor environmental parameters, so that the The environmental control mode of the environmental control device is suitable for the environmental change of the outdoor space at the preset time.

3. Use the processor to determine that the frequency distribution of the known outdoor environment parameters exhibits the Gaussian distribution, so as to ensure that the environment control mode of the environment control device is suitable for the normally distributed environment changes of the outdoor space.

4. The processor determines that the high point of the Gaussian distribution is at the center of the Gaussian distribution, so that the closed space has more stable environmental conditions.

5. The processor first classifies the preset time according to the environmental change factor, so that the data collected at one time does not change too drastically.

6. The processor records the known outdoor environment parameters that appear more than the predetermined number of times in the Gaussian distribution as the reference outdoor environment parameter range, so as to ensure that the known outdoor environment parameters are safe control ranges.

Combining the above technical features, the method of the present invention for adjusting the control mode of the environmental control equipment in the enclosed space according to the outdoor environmental parameters and the method for establishing a comparison database for the control mode of the environmental control equipment in the enclosed space according to the outdoor environmental parameters, the main effects of the present invention will be as follows: The following examples make this clear.

Referring to the first and second figures, an embodiment of the method for adjusting the control mode of the environmental control device in the enclosed space according to the outdoor environment parameters of the present invention is executed by a control system. The control system includes a processor 1 , a comparison database 2 , an environmental control device 3 , an outdoor environmental parameter sensor 4 , and an indoor environmental parameter sensor 5 . The method for adjusting a control mode of an environmental control device in an enclosed space according to an outdoor environment parameter includes a step S1 for establishing a comparison database, a step S2 for comparing, and a step S3 for executing.

The processor 1 is signal-connected with the comparison database 2 , the environmental control device 3 , the outdoor environmental parameter sensor 4 , and the indoor environmental parameter sensor 5 . The comparison database 2 may be a storage device electrically connected to the processor 1 or a cloud database. If the comparison database 2 is the cloud database, the processor 1 can use the network The road is connected to the cloud database signal. When the environmental control device 3 executes an environmental control mode, a closed space can maintain a required range of internal environmental parameters. scope. The environmental control device 3 includes at least one of a fan, a water wall, a heater, and an air conditioner. The comparison database 2 stores a plurality of reference outdoor environment parameter ranges, and each reference outdoor environment parameter range corresponds to one of the environmental control modes. Each reference outdoor environment parameter range is, for example, a range of any parameter such as a temperature, a humidity, a photon content, and a carbon dioxide content.

The step S1 of establishing a comparison database is to use the processor 1 to store a plurality of the environmental control modes corresponding to the environmental control device 3 in the reference outdoor environment parameter range to the comparison database 2 . The environmental control mode corresponding to each reference outdoor environment parameter range is established by the step S1 of establishing the comparison database. The step S1 of establishing a comparison database includes an internal data collection step S11, a first determination step S12, an adjustment step S13, an external data collection step S14, a second determination step S15, a third determination step S16, a The fourth determination step S17, and a storage step S18.

The internal data collection step S11 is to use the indoor environmental parameter sensor 5 to detect multiple internal detections in the environment control mode of the enclosed space under each reference outdoor environmental parameter range within a preset time. Environmental parameters, the processor 1 then collects the internally detected environmental parameters from the indoor environmental parameter sensor 5 . It should be noted that the processor 1 first classifies the preset time according to an environmental change factor, and the environmental change factor includes at least one of a factor of sunlight exposure and a seasonal change factor. For example, the preset time can be classified according to day and night or according to the four seasons of spring, summer, autumn and winter, and even the preset time can be classified according to morning and evening and four seasons. After classifying the preset time, the processor 1 collects the internally detected environment parameters within the classified preset time. For example, the processor 1 collects the internally detected environmental parameters for one spring night at a time, or collects the internally detected environmental parameters for one winter night at a time.

The first determination step S12 is to use the processor 1 to calculate the average value of the internally detected environmental parameters, and to determine whether the average value of the internally detected environmental parameters conforms to the range of the internal environmental parameters. If the average value of the environmental parameters does not conform to the internal environmental parameter range, the adjustment step S13 is performed. If the average value of the internally detected environmental parameters conforms to the internal environmental parameter range, the external data collection step S14 is performed.

The adjustment step S13 is to adjust the environment control mode corresponding to the environment control device 3 . After the adjustment is completed, return to the internal data collection step S11 , and then repeat the establishment and comparison database step S1 .

The external data collection step S14 is to use the outdoor environmental parameter sensor 4 to detect a plurality of known outdoor environmental parameters of an outdoor space outside the enclosed space, and the processor 1 then obtains the data from the outdoor environmental parameter sensor 4 Collect these known outdoor environmental parameters.

The second determination step S15 is to use the processor 1 to calculate the standard deviation of the internally detected environmental parameters and the standard deviation of the known outdoor environmental parameters, and to determine whether the standard deviation of the internally detected environmental parameters is smaller than the and other standard deviations of the known outdoor environmental parameters, if the standard deviations of the internally detected environmental parameters are not less than the standard deviations of the known outdoor environmental parameters, perform the adjustment step S13, if the standard deviations of the internally detected environmental parameters If the difference is smaller than the standard deviation of the known outdoor environment parameters, the third determination step S16 is performed. When the first determination step S12 and the second determination step S15 are met, it means that the environment control mode of the environment control device 3 is suitable for the environmental change of the outdoor space at the preset time.

The third determining step S16 is to use the processor 1 to sample the known outdoor environment parameters at intervals of an environment parameter interval, and count the occurrences of the known outdoor environment parameters for each sampling type after sampling, to obtain Obtain the order distribution of the known outdoor environment parameters, and determine whether the order distribution of the known outdoor environment parameters exhibits a Gaussian distribution, and if the order distribution of the known outdoor environment parameters does not exhibit the Gaussian distribution, perform the adjustment Step S13, if the frequency distribution of the known outdoor environment parameters exhibits the Gaussian distribution, execute the fourth determination step S17. When the order distribution of the known outdoor environment parameters exhibits the Gaussian distribution, it means that the order distribution of the known outdoor environment parameters is a normal distribution, and then the environmental control mode of the environmental control device 3 is suitable for the normal distribution. The environment of this outdoor space changes. As shown in the fourth figure, any of the known outdoor environmental parameters collected by the processor 1 is an ambient temperature during a winter day, and the environmental parameter interval is set to 0.5 ^° C, then the processor 1 will The known outdoor environmental parameters are sampled at 0.5 ^° C intervals, and the number of occurrences of these known outdoor environmental parameters in each sampling category after sampling is counted to obtain the frequency distribution of these known outdoor environmental parameters.

The fourth determination step S17 is to use the processor 1 to determine whether a high point of the Gaussian distribution is in a center of the Gaussian distribution, and if the high point of the Gaussian distribution is not in the center of the Gaussian distribution, execute the adjustment step S13, if the high point of the Gaussian distribution is at the center of the Gaussian distribution, execute the storing step S18. If the order distribution of the known outdoor environment parameters shows that the high point of the Gaussian distribution is at the center of the Gaussian distribution, it means that the Gaussian distribution is symmetrical, and the closed space can be made into a more stable environment condition. As shown in Figure 5, any of the known outdoor environmental parameters collected by the processor 1 is an ambient humidity in a winter night, and the environmental parameter interval is set to 5%. The environmental parameters are sampled at 5% intervals, and the frequency distribution of the known outdoor environmental parameters is obtained by counting the times. It can be seen from the fifth figure that the high point of the frequency distribution of the known outdoor environmental parameters is not in the above-mentioned known outdoor environmental parameters. The center of the frequency distribution of the known outdoor environment parameters is biased to the right, so the adjustment step S13 needs to be performed, and the step S1 of establishing a comparison database is performed again after adjusting the environmental control device 3 .

The storing step S18 is to use the processor 1 to retrieve the known outdoor environment parameters that appear more than a predetermined number of times in the Gaussian distribution and record them as the reference outdoor environment parameter range, and store the reference outdoor environment parameter range to the ratio to the database. For example, the predetermined number of times is 10 times, the processor 1 retrieves the known outdoor environment parameters that occur more than 10 times, and then retrieves a minimum value and a maximum value among the known outdoor environment parameters and records as the reference Outdoor environment parameter range. The processor 1 retrieves the known outdoor environment parameters that appear more than the predetermined number of times in the Gaussian distribution as a safe control range, so as to ensure that the environmental control mode of the environmental control device 3 can cope with the reference outdoor environmental parameter range. The change.

After the comparison database 2 is established, the comparison step S2 is continued. The comparison step S2 is to use the processor 1 to obtain an outdoor environment parameter to be adapted, and compare the outdoor environment parameter to be adapted to the reference outdoor environment parameter ranges in the comparison database 2 . If the to-be-adapted outdoor environment parameters do not fall within the range of the reference outdoor environment parameters, an administrator can manually or remotely control the operation of the environmental control device 3 to cope with the coming of the changing weather. If the to-be-adapted outdoor environment parameters If it falls within the range of one of the reference outdoor environment parameters, the execution step S3 is executed.

The execution step S3 is to use the processor 1 to control the environmental control device 3 to operate in the corresponding environmental control mode according to the matched reference outdoor environment parameter range. It should be added that, in the comparison step S2, when the outdoor environment parameter to be adapted falls within the range of a plurality of the reference outdoor environment parameters, the processor 1 compares the outdoor environment parameter to be adapted with the reference outdoor environment parameters A central value of each environmental parameter range is compared, and the processor 1 controls the environmental control device 3 to operate in the corresponding environmental control mode according to the reference outdoor environmental parameter range of the central value of the outdoor environmental parameter to be adapted.

Therefore, through long-term inductive analysis, the comparison database 2 can be established in advance to obtain the control conditions for the internal environmental parameter range required to maintain the enclosed space, that is, under each reference outdoor environmental parameter range, the loop The environmental control mode corresponding to the control device 3, as long as the to-be-adapted outdoor environment parameters of the outdoor space in the next period can be known, determine whether the to-be-adapted outdoor environment parameters are within the range of the comparison database 2, if If the parameters to be adapted to the outdoor environment are within the range of the comparison database 2, the environmental control device 3 can be pre-controlled to maintain an environment suitable for biological growth in the enclosed space. If the parameters to be adapted to the outdoor environment are not in the comparison Within the scope of the database 2, the administrator can manually or remotely control the operation of the environmental control device 3 to cope with the advent of severe weather.

To sum up, through the step S1 of establishing a comparison database, through long-term data accumulation, different multiple reference outdoor environment parameter ranges and corresponding multiples of the environmental control mode are established in advance, and then through the In the comparison step S2, as long as the parameters to be adapted to the outdoor environment are obtained in advance, the suitable environment control mode in the comparison database 2 can be compared, and can be implemented by the execution step S3. The environmental parameters are not within the scope of the comparison database 2, the administrator can manually or remotely control the operation of the environmental control device 3 to cope with the advent of severe weather, and can also use the step S1 of creating a comparison database , establish the reference outdoor environment parameter range that conforms to the to-be-adapted outdoor environment parameter, and through the first determination step S12 and the second determination step S15, so that the environment control mode of the environment control device 3 is suitable for the preset The environmental change of the outdoor space at the present time, and then the third judgment step S16 is used to ensure that the environmental control mode of the environmental control device 3 is suitable for the normal distribution of the environmental change of the outdoor space, and further by the fourth judgment In step S17, there is a more stable environmental condition in the closed space. In addition, in the internal data collection step S11, the processor 1 first classifies the preset time according to the environmental change factor. The collected data does not change too drastically, and in the storage step S18, the processor 1 retrieves the known outdoor environment parameters that appear more than the predetermined number of times in the Gaussian distribution and records them as the reference outdoor environment parameter range , to ensure that these known outdoor environmental parameters are within a safe control range.
