The system is configured to perform a determination execution process based on determination set information, which consists of execution target information indicating at least two of the three determination processing units to be executed, and execution priority information indicating the execution order of the at least two of the determination processing units indicated by the execution target information, and to execute the determination processing unit that is set to the earliest execution order among the unexecuted determination processing units as indicated by the execution priority information. Furthermore, if the determination processing unit executed in the determination execution process outputs a determination result indicating that the environment in the growing room is not appropriate, the system is configured to skip the execution of the determination processing by the remaining unexecuted determination processing units and execute a process to cause the ventilation control unit to switch the ventilation means to a ventilation state. If the determination processing unit executed in the determination execution process outputs a determination result indicating that the environment in the growing room is appropriate, the system is configured to execute the determination processing unit that is set to the earliest execution order among the remaining unexecuted determination processing units as indicated by the execution priority information.

Modes for Carrying Out the Invention

[0016] The following describes a plant cultivation facility according to one embodiment of the present invention, with reference to the attached drawings.

[0017] As shown in Figure 1, the plant cultivation equipment 1 according to this embodiment comprises a cultivation room 2 having a space for growing plants (for example, leafy vegetables) inside (hereinafter referred to as the cultivation space), a ventilation means 3 for ventilating the cultivation space, and a control device 4 that controls the operation state of the ventilation means 3.

[0018] Inside cultivation room 2, for example, a planter facility P for planting plants is installed.

[0019] The ventilation means 3 is configured to be switchable between a ventilation state in which the inside of the growing room 2 (growing space) is ventilated and a non-ventilated state in which the inside of the growing room 2 (growing space) is not ventilated.

[0020] As shown in Figure 2, the ventilation means 3 of this embodiment includes an exhaust passage 30 that communicates with the inside and outside of the growing room 2 and serves as a passage for air discharged from inside the growing room 2 to the outside of the growing room 2, a supply passage 31 that communicates with the inside and outside of the growing room 2 and serves as a passage for air supplied from outside the growing room 2 to the growing room 2, and a ventilation drive unit 32 that generates airflow in the exhaust passage 30 and the supply passage 31.

[0021] The exhaust passage 30 is connected to a through-hole (exhaust hole 20) formed in the wall surface of the growing chamber 2.

[0022] The air supply passage 31 is connected to a through-hole (air supply hole 21) formed in the wall surface of the growing chamber 2.

[0023] The ventilation drive unit 32 includes a drive source (motor) 320 and a driven rotating unit 321 having a plurality of blades and configured to rotate by receiving the driving force of the drive source 320.

[0024] The ventilation drive unit 32 is configured such that when the drive source 320 is driven, the driven rotating part 321 rotates in response to the driving force of the drive source 320, and when the drive source 320 is stopped, it switches to a stopped state in which the driven rotating part 321 is stopped.

[0025] Therefore, the ventilation means 3 is configured such that when the ventilation drive unit 32 is driven, the air inside the growing room 2 is discharged to the outside of the growing room 2 through the exhaust passage 30, and air from outside the growing room 2 is drawn into the growing room 2 through the supply passage 31 (i.e., a ventilation state in which the growing room 2 is ventilated), and when the ventilation drive unit 32 is stopped, the airflow in the exhaust passage 30 and the airflow in the supply passage 31 are stopped (i.e., a non-ventilated state in which the growing room 2 is not ventilated).

[0026] As shown in Figure 1, the growth room 2 of this embodiment is installed inside the building 5. The building 5 is provided with an air conditioning room 50 where air conditioning equipment 500 is installed, and the growth room 2 is installed inside this air conditioning room 50. Therefore, when the ventilation means 3 is in the ventilation state, the air inside the growth room 2 and the air inside the air conditioning room 50 are exchanged.

[0027] The air conditioning equipment 500 is capable of adjusting the temperature and humidity inside the air-conditioned room 50. By adjusting the temperature and humidity inside the air-conditioned room 50 to the desired state using the air conditioning equipment 500, the condition of the air exchanged with the air inside the growing room 2 can be maintained.

[0028] The control device 4 may be configured as, for example, a computer.

[0029] The control device 4 includes an information acquisition unit 40 that acquires information representing the environment (state) inside the growing room 2, a ventilation determination unit 41 that determines whether the environment inside the growing room 2 is appropriate or not, a determination command unit 42 that sends an operation command to the ventilation determination unit 41, a ventilation control unit 43 that sends an operation command to the ventilation means 3 (which controls the state of the ventilation means 3 to switch between a ventilated state and a non-ventilated state) based on the determination result output from the ventilation determination unit 41, an operation setting unit 44 that sets the operation of the determination command unit 42, and a storage unit 45 that stores information.

[0030] The information acquisition unit 40 includes a carbon dioxide concentration information acquisition unit 400 that acquires information indicating the measured value of carbon dioxide concentration in the growth chamber 2, a humidity information acquisition unit 401 that acquires information indicating the measured value of humidity in the growth chamber 2, and a temperature information acquisition unit 402 that acquires information indicating the measured value of temperature in the growth chamber 2.

[0031] The carbon dioxide concentration information acquisition unit 400 is configured to acquire information (hereinafter referred to as concentration measurement value information D1) indicating the measured value of carbon dioxide concentration in the growth chamber 2, which is measured by a carbon dioxide concentration sensor S1 installed in the growth chamber 2.

[0032] Furthermore, the carbon dioxide concentration information acquisition unit 400 is configured to acquire the concentration measurement value information D1 and then execute a process to store (write) it to the storage unit 45.

[0033] The carbon dioxide concentration information acquisition unit 400 only needs to be connected to the carbon dioxide concentration sensor S1 by wire or wireless connection, and may be directly connected to the carbon dioxide concentration sensor S1 or indirectly connected via other equipment.

[0034] Furthermore, the carbon dioxide concentration information acquisition unit 400 may be configured to receive the measured value of carbon dioxide concentration as an electrical signal, or as a digital signal.

[0035] The humidity information acquisition unit 401 is configured to acquire information indicating the measured humidity inside the growing room 2, for example, measured by a humidity sensor S2 installed inside the growing room 2 (hereinafter referred to as humidity measurement value information D2).

[0036] Furthermore, the humidity information acquisition unit 401 is configured to execute a process to write the humidity measurement value information D2 to the storage unit 45 once it has acquired it.

[0037] The humidity information acquisition unit 401 only needs to be connected to the humidity sensor S2 by wire or wireless connection, and may be directly connected to the humidity sensor S2 or indirectly connected via other equipment.

[0038] Furthermore, the humidity information acquisition unit 401 may be configured to receive the measured humidity value as an electrical signal, or as a digital signal.

[0039] The temperature information acquisition unit 402 is configured to acquire, for example, information indicating the measured temperature inside the growing room 2 measured by a temperature sensor S3 installed inside the growing room 2 (hereinafter referred to as temperature measurement value information D3).

[0040] Furthermore, the temperature information acquisition unit 402 is configured to execute a process to write the temperature measurement value information D3 to the storage unit 45 once it has acquired it.

[0041] The temperature information acquisition unit 402 only needs to be connected to the temperature sensor S3 by wire or wireless connection, and may be directly connected to the temperature sensor S3 or indirectly connected via other equipment.

[0042] Furthermore, the temperature information acquisition unit 402 may be configured to receive the measured temperature as an electrical signal or as a digital signal.

[0043] The ventilation determination unit 41 has three determination processing units: a carbon dioxide concentration determination processing unit 410 that performs a process to determine whether the environment inside the growing room 2 is appropriate based on the carbon dioxide concentration value inside the growing room 2; a humidity determination processing unit 411 that performs a process to determine whether the environment inside the growing room 2 is appropriate based on the humidity (relative humidity) value inside the growing room 2; and a temperature determination processing unit 412 that performs a process to determine whether the environment inside the growing room 2 is appropriate based on the temperature value inside the growing room 2.

[0044] The carbon dioxide concentration determination processing unit 410 is configured to perform an acquisition process to acquire concentration measurement value information D1 and a determination process to determine whether the carbon dioxide concentration in the growth chamber 2 is appropriate based on the acquired concentration measurement value information D1.

[0045] The carbon dioxide concentration determination processing unit 410, in the determination process, compares the concentration measurement information D1 acquired in the acquisition process with the concentration conditions that indicate the conditions for determining whether the carbon dioxide concentration in the growth chamber 2 is appropriate or not, and determines whether the carbon dioxide concentration is appropriate or not. Specifically, if the conditions for determining appropriateness are set as the concentration conditions, and the concentration measurement information D1 satisfies the concentration conditions, it is determined that the carbon dioxide concentration in the growth chamber 2 is appropriate. If the humidity measurement information D2 does not satisfy the humidity conditions, it is determined that the carbon dioxide concentration in the growth chamber 2 is not appropriate.

[0046] The concentration conditions in this embodiment are indicated by a numerical range of carbon dioxide concentration that constitutes an appropriate state. The concentration conditions include an upper concentration threshold, which is the upper limit of the carbon dioxide concentration that constitutes an appropriate state, and a lower concentration threshold, which is the lower limit of the carbon dioxide concentration that constitutes an appropriate state. The numerical range of carbon dioxide concentration that constitutes an appropriate state is determined by these upper and lower concentration thresholds.

[0047] The timing for initially setting the upper and lower concentration thresholds as concentration conditions can be any time before the plant cultivation equipment 1 is put into use, for example, at the time of manufacturing the plant cultivation equipment 1 or after its manufacture. Furthermore, it is preferable that the plant cultivation equipment 1 allows the settings of the upper and lower concentration thresholds that were initially set as concentration conditions to be changed.

[0048] In the determination process, the carbon dioxide concentration determination processing unit 410 determines that the carbon dioxide concentration in the growing chamber 2 is appropriate if the carbon dioxide value indicated by the concentration measurement information D1 is below the upper concentration threshold and above the lower concentration threshold, and determines that it is not appropriate if the carbon dioxide value indicated by the concentration measurement information D1 exceeds the upper concentration threshold, or if the carbon dioxide value indicated by the concentration measurement information D1 falls below the lower concentration threshold.

[0049] Furthermore, if the carbon dioxide concentration determination processing unit 410 determines that the carbon dioxide concentration in the growth chamber 2 is appropriate, it sends an appropriate notification to the determination command unit 42 indicating that, and if it determines that the carbon dioxide concentration in the growth chamber 2 is not appropriate, it sends an inappropriate notification to the determination command unit 42 indicating that.

[0050] The humidity determination processing unit 411 is configured to perform an acquisition process to obtain humidity measurement value information D2 and to determine whether the humidity inside the growing room 2 is appropriate based on the acquired humidity measurement value information D2.

[0051] In the determination process, the humidity determination processing unit 411 compares the humidity measurement information D2 acquired in the acquisition process with the humidity conditions that indicate whether the humidity in the growing room 2 is appropriate or not, and determines whether the humidity is appropriate or not. Specifically, if the conditions for determining appropriateness are set as humidity conditions and the humidity measurement information D2 satisfies the humidity conditions, it is determined that the humidity in the growing room 2 is appropriate. If the humidity measurement information D2 does not satisfy the humidity conditions, it is determined that the humidity in the growing room 2 is not appropriate.

[0052] The humidity conditions in this embodiment are indicated by a numerical range of humidity that constitutes an appropriate state. The humidity conditions include an upper humidity threshold, which is the upper limit of humidity that constitutes an appropriate state, and a lower humidity threshold, which is the lower limit of humidity that constitutes an appropriate state. The numerical range of humidity that constitutes an appropriate state is determined by these upper and lower humidity thresholds.

[0053] The timing for initially setting the humidity upper and lower threshold values ​​as humidity conditions can be any time before the plant cultivation equipment 1 is put into use, for example, at the time of manufacturing the plant cultivation equipment 1 or after its manufacture. Furthermore, it is preferable that the plant cultivation equipment 1 allows the initially set humidity upper and lower threshold values ​​to be changed.

[0054] The humidity determination processing unit 411 is configured to determine that the humidity in the growing room 2 is appropriate if the humidity value indicated by the humidity measurement information D2 is below the upper humidity threshold and above the lower humidity threshold, and to determine that it is not appropriate if the humidity value indicated by the humidity measurement information D2 exceeds the upper humidity threshold, or if the humidity value indicated by the humidity measurement information D2 falls below the lower humidity threshold.

[0055] Furthermore, if the humidity determination processing unit 411 determines that the humidity in the growing room 2 is appropriate, it sends an appropriate notification to the determination command unit 42 indicating that, and if it determines that the humidity in the growing room 2 is not appropriate, it sends an inappropriate notification to the determination command unit 42 indicating that.

[0056] The temperature determination processing unit 412 is configured to perform an acquisition process to obtain temperature measurement information D3 and to determine whether the temperature inside the growth chamber 2 is appropriate based on the acquired temperature measurement information D3.

[0057] In the determination process, the temperature determination processing unit 412 compares the temperature measurement information D3 acquired in the acquisition process with the temperature conditions that indicate whether the temperature inside the growth chamber 2 is appropriate or not, and determines whether the temperature is appropriate or not. Specifically, if the conditions for determining appropriateness are set as humidity conditions, and the temperature measurement information D3 satisfies the temperature conditions, the temperature inside the growth chamber 2 is determined to be appropriate. If the temperature measurement information D3 does not satisfy the temperature conditions, the temperature inside the growth chamber 2 is determined to be inappropriate.

[0058] In this embodiment, the temperature conditions are indicated by a numerical range of temperatures that constitute an appropriate state. The temperature conditions include an upper temperature threshold, which is the upper limit of the temperature that constitutes an appropriate state, and a lower temperature threshold, which is the lower limit of the temperature that constitutes an appropriate state. The numerical range of temperatures that constitute an appropriate state is determined by these upper and lower temperature thresholds.

[0059] The timing for initially setting the upper and lower temperature thresholds as temperature conditions can be any time before the plant cultivation equipment 1 is put into use, for example, at the time of manufacturing the plant cultivation equipment 1 or after its manufacture. Furthermore, it is preferable that the plant cultivation equipment 1 allows the initially set upper and lower temperature thresholds to be changed.

[0060] The temperature determination processing unit 412 is configured to determine that the temperature inside the growing chamber 2 is appropriate if the temperature value indicated by the temperature measurement information D3 is below the upper temperature threshold and above the lower temperature threshold, and to determine that the temperature is not appropriate if the temperature value indicated by the temperature measurement information D3 is above the upper temperature threshold, or below the lower temperature threshold.

[0061] Furthermore, if the temperature determination processing unit 412 determines that the temperature inside the growth chamber 2 is appropriate, it sends an appropriate notification to the determination command unit 42 indicating that the temperature inside the growth chamber 2 is appropriate, and if it determines that the temperature inside the growth chamber 2 is not appropriate, it sends an inappropriate notification to the determination command unit 42 indicating that the temperature inside the growth chamber 2 is inappropriate.

[0062] The determination command unit 42 is configured to perform processing based on determination set information D4, which is formed by associating execution target information D40, which indicates at least two of the three determination processing units to be executed, with execution priority information D41, which indicates the execution order of each of the at least two determination processing units indicated by the execution target information D40 (see Figure 3).

[0063] Furthermore, the determination command unit 42 of this embodiment can use three operating modes: a single mode that uses one determination set information that cannot be changed by the user, a multi-mode that uses multiple (three in this embodiment) determination set information by switching between them, and a free mode that uses one determination set information that can be changed by the user.

[0064] The determination command unit 42 is configured to repeatedly perform determination execution processing, executing unexecuted determination processing units in order from the earliest to the earliest, according to the execution priority information, when single mode is selected.

[0065] Furthermore, if the determination processing unit determines that the environment inside the growing room 2 is not appropriate, the determination command unit 42 receives an inappropriateness notification from the determination processing unit, skips the execution of the remaining unexecuted determination processing units, and sends a ventilation start command to the ventilation control unit 43. Upon receiving the ventilation start command, the ventilation control unit 43 executes a process to switch the ventilation means 3 to the ventilation state.

[0066] On the other hand, if the determination processing unit determines that the environment in the cultivation room 2 is appropriate, the determination command unit 42 receives an appropriate notification from the determination processing unit and continues the determination execution process, executing the processing of the determination processing unit that is set in the earliest order indicated by the execution priority information among the remaining unexecuted determination processing units.

[0067] For example, in the single-mode determination set information D4 shown in Figure 3, the execution order of the carbon dioxide concentration determination processing unit 410 is first, the execution order of the temperature determination processing unit 412 is second, and the execution order of the humidity determination processing unit 411 is third. Therefore, the determination command unit 42 executes the determination process by the carbon dioxide concentration determination processing unit 410, the determination process by the temperature determination processing unit 412, and the determination process by the humidity determination processing unit 411 in that order.

[0068] When multi-mode is selected, the judgment command unit 42 is configured to repeatedly execute judgment execution processes in the same way as in single mode, executing the unexecuted judgment processing units in order from the earliest execution priority information indicated by the execution priority information. However, when the judgment set information to be used is switched, at least one of the execution targets and execution order (in this embodiment, the execution order) of the carbon dioxide concentration judgment processing unit 410, the humidity judgment processing unit 411, and the temperature judgment processing unit 412 changes.

[0069] In the same way as in single mode, if the judgment processing unit determines that the environment inside the growing room 2 is not appropriate while the judgment command unit 42 is executing the judgment execution process in multi-mode, the judgment command unit 42 receives an inappropriateness notification from the judgment processing unit and skips the execution of the remaining unexecuted judgment processing units. In this case as well, the judgment command unit 42 sends a ventilation start command to the ventilation control unit 43, and upon receiving the ventilation start command, the ventilation control unit 43 executes a process to switch the ventilation means 3 to the ventilation state.

[0070] For example, if the first of the multi-mode determination set information D4 shown in Figure 3, which is the determination set information on the far left in Figure 3, is selected, the execution order of the temperature determination processing unit 412 is first, the execution order of the carbon dioxide concentration determination processing unit 410 is second, and the execution order of the humidity determination processing unit 411 is third. Therefore, the determination command unit 42 executes the determination process by the temperature determination processing unit 412, the determination process by the carbon dioxide concentration determination processing unit 410, and the determination process by the humidity determination processing unit 411 in that order.

[0071] If the system switches to the second of the multi-mode determination set information D4, which is the determination set information D4 in the center of Figure 3, the execution order of the carbon dioxide concentration determination processing unit 410 is first, the execution order of the temperature determination processing unit 412 is second, and the execution order of the humidity determination processing unit 411 is third. Therefore, the determination command unit 42 executes the determination process by the carbon dioxide concentration determination processing unit 410, the determination process by the temperature determination processing unit 412, and the determination process by the humidity determination processing unit 411 in that order.

[0072] If the system switches to the third of the multi-mode determination set information D4, which is the determination set information D4 on the far right of Figure 3, the execution order of the humidity determination processing unit 411 is first, the execution order of the carbon dioxide concentration determination processing unit 410 is second, and the execution order of the carbon dioxide concentration determination processing unit 410 is third. Therefore, the determination command unit 42 executes the determination process by the humidity determination processing unit 411, the determination process by the carbon dioxide concentration determination processing unit 410, and the determination process by the temperature determination processing unit 412 in that order.

[0073] The determination command unit 42 is configured to repeatedly perform the determination execution process, executing the unexecuted determination processing units in order from the earliest order indicated by the execution priority information, even when free mode information is selected. However, if the settings of the determination set information are changed, the execution order of the carbon dioxide concentration determination processing unit 410, the humidity determination processing unit 411, and the temperature determination processing unit 412 will change.

[0074] In the free mode judgment execution process by the judgment command unit 42, if the judgment processing unit determines that the environment in the growing room 2 is not appropriate, the judgment command unit 42 receives an inappropriateness notification from the judgment processing unit and skips the execution of the remaining unexecuted judgment processing units, just as in single mode. In this case as well, the judgment command unit 42 sends a ventilation start command to the ventilation control unit 43, and upon receiving the ventilation start command, the ventilation control unit 43 executes a process to switch the ventilation means 3 to the ventilation state.

[0075] For example, in the free mode judgment set information D4 shown in Figure 3, the execution order of the carbon dioxide concentration judgment processing unit 410 is first, the execution order of the humidity judgment processing unit 411 is second, and the execution order of the temperature judgment processing unit 412 is third. Therefore, the judgment command unit 42 executes the judgment process by the carbon dioxide concentration judgment processing unit 410, the judgment process by the humidity judgment processing unit 411, and the judgment process by the temperature judgment processing unit 412 in that order.

[0076] The ventilation control unit 43 is configured to execute a process to obtain a ventilation start command or a ventilation stop command transmitted from the determination command unit 42. If a ventilation start command is obtained, it executes a process to switch the ventilation means 3 to a ventilation state, and after a predetermined time has elapsed, it executes a process to switch the ventilation means 3 to a non-ventilation state.

[0077] The ventilation start command acquired by the ventilation control unit 43 is a command sent from the determination command unit 42 according to the determination result of one of the following: the determination result of the carbon dioxide concentration determination processing unit 410, the determination result of the humidity determination processing unit 411, or the determination result of the temperature determination processing unit 412. Therefore, the ventilation control unit 43 is able to control the state of the ventilation means 3 to the ventilation state according to the determination result of one of the following: the determination result of the carbon dioxide concentration determination processing unit 410, the determination result of the humidity determination processing unit 411, or the determination processing unit 412.

[0078] The operation setting unit 44 includes a mode switching unit 440 that switches the operation mode of the determination command unit 42, and a set setting unit 441 that changes the settings of the determination set information used in free mode.

[0079] The mode switching unit 440 can select one of single mode, multi mode, or free mode, and sets the operation mode of the determination command unit 42 to the selected operation mode.

[0080] The set setting unit 441 allows the user to specify which of the carbon dioxide concentration determination processing unit 410, humidity determination processing unit 411, and temperature determination processing unit 412 to use, and is configured to set the information to be executed based on the specified result.

[0081] Furthermore, the set setting unit 441 can set the execution order of the selected target from the carbon dioxide concentration determination processing unit 410, the humidity determination processing unit 411, and the temperature determination processing unit 412, and is configured to set execution priority information based on the result of setting the execution order.

[0082] The memory unit 45 is described in the example of being built into the control device 4, but it may also be composed of components outside the control device 4.

[0083] The configuration of the plant cultivation equipment 1 according to this embodiment is as described above. Next, an example of the operation of the plant cultivation equipment 1 will be explained. It is assumed that the judgment set information is initially set to the contents shown in Figure 3.

[0084] Before using the plant cultivation equipment 1, the mode switching unit 440 selects whether the operation mode of the determination command unit 42 is single mode, multi mode, or free mode.

[0085] When the operation setting unit 44 selects single mode as the operation mode of the determination command unit 42, as shown in Figure 4, first the determination process is performed by the carbon dioxide concentration determination processing unit 410, which is set to the earliest execution order (1) among all determination processing units as indicated by the execution priority information (S10).

[0086] If the carbon dioxide concentration determination processing unit 410 determines that the carbon dioxide concentration in the growing chamber 2 is not appropriate (No in S11), the carbon dioxide concentration determination processing unit 410 sends an inappropriate notification to the determination command unit 42, and the determination command unit 42 skips the execution of any unexecuted determination processing units and executes a process to switch the ventilation means 3 to a ventilation state (S12). Specifically, the determination command unit 42 sends a ventilation start command to the ventilation control unit 43, and the ventilation control unit 43, upon receiving the ventilation start command, executes a process to switch the ventilation means 3 to a ventilation state. After a predetermined time has elapsed and the ventilation means 3 has switched to a non-ventilated state (S13), if the determination execution process is not terminated (No in S14), the determination command unit 42 returns to executing the determination processing unit that has the earliest execution order (1) among all determination processing units as indicated by the execution priority information (specifically, S10).

[0087] On the other hand, if the carbon dioxide concentration determination processing unit 410 determines that the carbon dioxide concentration in the growth chamber 2 is appropriate (Yes in S11), the carbon dioxide concentration determination processing unit 410 sends an appropriate notification to the determination command unit 42, and the determination command unit 42 executes the determination process by the temperature determination processing unit 412, which is set to the earliest execution order (2) among the remaining unexecuted determination processing units as indicated by the execution priority information (S15).

[0088] If the temperature determination processing unit 412 determines that the temperature in the growing chamber 2 is not appropriate (No in S16), the temperature determination processing unit 412 sends an inappropriateness notification to the determination command unit 42, and the determination command unit 42 skips the execution of any unexecuted determination processing units and executes the process to switch the ventilation means 3 to the ventilation state (S12). Specifically, the determination command unit 42 sends a ventilation start command to the ventilation control unit 43, and upon receiving the ventilation start command, the ventilation control unit 43 executes the process to switch the ventilation means 3 to the ventilation state. After a predetermined time has elapsed and the ventilation means 3 has switched to the non-ventilated state (S13), if the determination execution process is not terminated (No in S14), the determination command unit 42 returns to executing the determination processing unit that has the earliest execution order (1) among all determination processing units as indicated by the execution priority information (specifically, S10).

[0089] On the other hand, if the temperature determination processing unit 412 determines that the temperature in the growing chamber 2 is appropriate (Yes in S16), the temperature determination processing unit 412 sends an appropriate notification to the determination command unit 42, and the determination command unit 42 executes the determination process by the humidity determination processing unit 411, which is the remaining unexecuted determination processing unit (S17).

[0090] If the humidity determination processing unit 411 determines that the humidity level in the growing room 2 is not appropriate (No in S18), the humidity determination processing unit 411 sends an inappropriate notification to the determination command unit 42, and the determination command unit 42 executes a process to switch the ventilation means 3 to the ventilation state (S12). Specifically, the determination command unit 42 sends a ventilation start command to the ventilation control unit 43, and upon receiving the ventilation start command, the ventilation control unit 43 executes a process to switch the ventilation means 3 to the ventilation state. After a predetermined time has elapsed and the ventilation means 3 has switched to the non-ventilation state (S13), if the determination item processing is not terminated (No in S14), the process returns to the execution of the determination processing unit that has the earliest execution order (1) among all the determination processing units as indicated by the execution priority information (specifically, S10).

[0091] On the other hand, if the humidity determination processing unit 411 determines that the humidity level in the growing room 2 is appropriate (Yes in S18), the humidity determination processing unit 411 sends an appropriate notification to the determination command unit 42. In this case as well, the execution returns to the determination processing unit that has the earliest execution order (1) among all the determination processing units as indicated by the execution priority information (specifically, S10).

[0092] If the operation setting unit 44 has selected multi-mode as the operation mode for the determination command unit 42, first, a process is performed to select one of the three determination set information D4 (see Figure 3) to use, and then the determination command unit 42 executes a determination execution process based on the selected determination set information D4. Furthermore, if another determination set information D4 is selected for use while the determination execution process is in progress, the determination command unit 42 terminates the currently running determination execution process and then executes a determination execution process based on the other determination set information D4.

[0093] The following describes the flow of the judgment execution process of the judgment command unit 42 when the leftmost judgment set information D4 of the three judgment set information D4 for multimode shown in Figure 3 is selected, referring to Figure 5, and the flow of the judgment execution process of the judgment command unit 42 when the rightmost judgment set information D4 of the three judgment set information D4 for multimode shown in Figure 3 is selected, referring to Figure 6. The flow of the judgment execution process of the judgment command unit 42 when the central judgment set information D4 of the three judgment set information D4 for multimode shown in Figure 3 is selected is the same as the flow of the judgment execution process based on the judgment set information D4 for single mode shown in Figure 4.

[0094] If the leftmost of the three judgment set information D4 for multimode (see Figure 3) is selected, the processing by the temperature judgment processing unit 412, which is set to the earliest execution order (1) among all judgment processing units as indicated by the execution priority information, is executed (S20), as shown in Figure 5.

[0095] Then, if the temperature determination processing unit 412 determines that the temperature in the growing room 2 is not appropriate (No in S21), the temperature determination processing unit 412 sends an inappropriate notification to the determination command unit 42, and the determination command unit 42 skips the execution of any unexecuted determination processing units and executes the process to switch the ventilation means 3 to the ventilation state (S22). Specifically, the determination command unit 42 sends a ventilation start command to the ventilation control unit 43, and the ventilation control unit 43, upon receiving the ventilation start command, executes the process to switch the ventilation means 3 to the ventilation state. After a predetermined time has elapsed and the ventilation means 3 has switched to the non-ventilated state (S23), if the determination execution process is not terminated (No in S24), the determination command unit 42 returns to executing the determination processing unit that has the earliest execution order (1) among all determination processing units as indicated by the execution priority information (specifically, S20).

[0096] On the other hand, if the temperature determination processing unit 412 determines that the temperature in the growing chamber 2 is appropriate (Yes in S21), the temperature determination processing unit 412 sends an appropriate notification to the determination command unit 42, and the determination command unit 42 executes the processing by the carbon dioxide concentration determination processing unit 410, which is set to the earliest execution order (2) among the remaining unexecuted determination processing units as indicated by the execution priority information (S25).

Specifically, the determination command unit 42 sends a ventilation start command to the ventilation control unit 43, and upon receiving the ventilation start command, the ventilation control unit 43 executes the process to switch the ventilation means 3 to the ventilation state. After a predetermined time has elapsed and the ventilation means 3 has switched to the non-ventilation state (S23), if the determination execution process is not terminated (No in S24), the determination command unit 42 returns to executing the determination processing unit that has the earliest execution order (1) among all determination processing units as indicated by the execution priority information (specifically, S20).

[0098] On the other hand, if the carbon dioxide concentration determination processing unit 410 determines that the carbon dioxide concentration in the growing chamber 2 is appropriate (Yes in S26), the carbon dioxide concentration determination processing unit 410 sends an appropriate notification to the determination command unit 42, and the determination command unit 42 executes the processing by the remaining unexecuted determination processing unit, the humidity determination processing unit 411 (S27).

[0099] If the humidity determination processing unit 411 determines that the humidity level in the growing room 2 is not appropriate (No in S28), the humidity determination processing unit 411 sends an inappropriate notification to the determination command unit 42, and the determination command unit 42 executes a process to switch the ventilation means 3 to the ventilation state (S22). Specifically, the determination command unit 42 sends a ventilation start command to the ventilation control unit 43, and upon receiving the ventilation start command, the ventilation control unit 43 executes a process to switch the ventilation means 3 to the ventilation state. After a predetermined time has elapsed and the ventilation means 3 has switched to the non-ventilation state (S23), if the determination execution process is not terminated (No in S24), the execution returns to the determination processing unit that has the earliest execution order (1) among all determination processing units as indicated by the execution priority information (specifically, S20).

[0100] On the other hand, if the humidity determination processing unit 411 determines that the humidity level in the growing room 2 is appropriate (Yes in S28), the humidity determination processing unit 411 sends an appropriate notification to the determination command unit 42. In this case as well, the execution returns to the determination processing unit that has the earliest execution order (1) among all the determination processing units as indicated by the execution priority information (specifically, S20).

[0101] If the operation setting unit 44 has selected multi-mode as the operation mode for the determination command unit 42, and the central determination set information D4 (see Figure 3) among the three determination set information D4 for multi-mode is selected, the operation flow of the determination command unit 42 changes. In this case, the operation of the determination command unit 42 is the same as the operation flow of the determination command unit 42 shown in Figure 4.

[0102] Then, if the rightmost of the three judgment set information D4 for multimode (see Figure 3) is selected, the humidity judgment processing unit 411 will first perform processing as shown in Figure 6 (S30).

[0103] If the humidity determination processing unit 411 determines that the humidity level in the growing room 2 is not appropriate (No in S31), the humidity determination processing unit 411 sends an inappropriateness notification to the determination command unit 42, and the determination command unit 42 skips the execution of any unexecuted determination processing units and executes a process to switch the ventilation means 3 to a ventilation state (S32). Specifically, the determination command unit 42 sends a ventilation start command to the ventilation control unit 43, and upon receiving the ventilation start command, the ventilation control unit 43 executes a process to switch the ventilation means 3 to a ventilation state. After a predetermined time has elapsed and the ventilation means 3 has switched to a non-ventilated state (S33), if the determination execution process is not terminated (No in S34), the determination command unit 42 returns to executing the determination processing unit that has the earliest execution order (1) among all determination processing units as indicated by the execution priority information (specifically, S30).

[0104] On the other hand, if the humidity determination processing unit 411 determines that the temperature in the growing chamber 2 is appropriate (Yes in S31), the humidity determination processing unit 411 sends an appropriate notification to the determination command unit 42, and the determination command unit 42 executes the processing by the carbon dioxide concentration determination processing unit 410, which is set to the earliest execution order (2) among the remaining unexecuted determination processing units as indicated by the execution priority information (S35).

[0105] If the carbon dioxide concentration determination processing unit 410 determines that the carbon dioxide concentration in the growing chamber 2 is not appropriate (No in S36), the carbon dioxide concentration determination processing unit 410 sends an inappropriateness notification to the determination command unit 42, and the determination command unit 42 skips the execution of any unexecuted determination processing units and executes a process to switch the ventilation means 3 to a ventilation state (S32). Specifically, the determination command unit 42 sends a ventilation start command to the ventilation control unit 43, and the ventilation control unit 43, upon receiving the ventilation start command, executes a process to switch the ventilation means 3 to a ventilation state. After a predetermined time has elapsed and the ventilation means 3 has switched to a non-ventilated state (S33), if the determination execution process is not terminated (No in S34), the determination command unit 42 returns to executing the determination processing unit that is set to the earliest execution order (1) among all determination processing units as indicated by the execution priority information (specifically, S30).

[0106] On the other hand, if the carbon dioxide concentration determination processing unit 410 determines that the carbon dioxide concentration in the growth chamber 2 is appropriate (Yes in S36), the carbon dioxide concentration determination processing unit 410 sends an appropriate notification to the determination command unit 42, and the determination command unit 42 executes the processing by the temperature determination processing unit 412, which is the remaining unexecuted determination processing unit (S37).

[0107] If the temperature determination processing unit 412 determines that the temperature in the growing chamber 2 is not appropriate (No in S38), the temperature determination processing unit 412 sends an inappropriate notification to the determination command unit 42, and the determination command unit 42 executes a process to switch the ventilation means 3 to the ventilation state (S32). Specifically, the determination command unit 42 sends a ventilation start command to the ventilation control unit 43, and the ventilation control unit 43, upon receiving the ventilation start command, executes a process to switch the ventilation means 3 to the ventilation state. After a predetermined time has elapsed and the ventilation means 3 has switched to the non-ventilation state (S33), if the determination execution process is not terminated (No in S34), the execution returns to the determination processing unit that has the earliest execution order (1) among all the determination processing units as indicated by the execution priority information (specifically, S30).

[0108] On the other hand, if the temperature determination processing unit 412 determines that the temperature in the growing chamber 2 is appropriate (Yes in S38), the temperature determination processing unit 412 sends an appropriate notification to the determination command unit 42. In this case as well, the execution returns to the determination processing unit that has the earliest execution order (1) among all the determination processing units as indicated by the execution priority information (specifically, S30).

[0109] When the operation setting unit 44 selects free mode as the operation mode of the determination command unit 42, for example, based on the determination set information D4 set to be used in free mode as shown in Figure 7, the carbon dioxide concentration determination processing unit 410, which is set to have the earliest execution order (1) among all determination processing units as indicated by the execution priority information, will execute the processing (S40).

[0110] If the carbon dioxide concentration determination processing unit 410 determines that the carbon dioxide concentration in the growing chamber 2 is not appropriate (No in S41), the carbon dioxide concentration determination processing unit 410 sends an inappropriate notification to the determination command unit 42, and the determination command unit 42 skips the execution of any unexecuted determination processing units and executes the process to switch the ventilation means 3 to the ventilation state (S42). Specifically, the determination command unit 42 sends a ventilation start command to the ventilation control unit 43, and the ventilation control unit 43, upon receiving the ventilation start command, executes the process to switch the ventilation means 3 to the ventilation state. After a predetermined time has elapsed and the ventilation means 3 has switched to the non-ventilated state (S43), if the determination execution process is not terminated (No in S44), the determination command unit 42 returns to executing the determination processing unit that is set to the earliest execution order (1) among all determination processing units as indicated by the execution priority information (specifically, S40).

[0112] If the humidity determination processing unit 411 determines that the humidity level in the growing room 2 is not appropriate (No in S46), the humidity determination processing unit 411 sends an inappropriate notification to the ventilation control unit 43 and the determination command unit 42. The determination command unit 42 skips the execution of any unexecuted determination processing units and executes a process to switch the ventilation means 3 to a ventilation state (S42). Specifically, the determination command unit 42 sends a ventilation start command to the ventilation control unit 43, and upon receiving the ventilation start command, the ventilation control unit 43 executes a process to switch the ventilation means 3 to a ventilation state. After a predetermined time has elapsed and the ventilation means 3 has switched to a non-ventilated state (S43), if the determination execution process is not terminated (No in S44), the determination command unit 42 returns to executing the determination processing unit that has the earliest execution order (1) among all determination processing units as indicated by the execution priority information (specifically, S40).

[0113] On the other hand, if the humidity determination processing unit 411 determines that the humidity level inside the growing chamber 2 is appropriate (Yes in S46), the humidity determination processing unit 411 sends an appropriate notification to the determination command unit 42, and the determination command unit 42 executes the processing performed by the temperature determination processing unit 412, which is the remaining unexecuted determination processing unit (S47).

[0114] If the temperature determination processing unit 412 determines that the temperature in the growing room 2 is not appropriate (No in S47), the temperature determination processing unit 412 sends an inappropriate notification to the ventilation control unit 43 and the determination command unit 42, and the determination command unit 42 executes a process to switch the ventilation means 3 to the ventilation state (S42). Specifically, the determination command unit 42 sends a ventilation start command to the ventilation control unit 43, and upon receiving the ventilation start command, the ventilation control unit 43 executes a process to switch the ventilation means 3 to the ventilation state. After a predetermined time has elapsed and the ventilation means 3 has switched to the non-ventilation state (S43), if the determination execution process is not terminated (No in S44), the determination command unit 42 returns to executing the determination processing unit that has the earliest execution order (1) among all the determination processing units as indicated by the execution priority information (specifically S40).

[0115] On the other hand, if the temperature determination processing unit 412 determines that the temperature in the growing chamber 2 is appropriate (Yes in S48), the temperature determination processing unit 412 sends an appropriate notification to the determination command unit 42. In this case as well, the execution returns to the determination processing unit that has the earliest execution order (1) among all the determination processing units as indicated by the execution priority information (specifically, S40).

[0116] As described above, ventilation is performed according to the environment inside the rearing room 2.

[0117] As described above, with the plant cultivation equipment 1 according to this embodiment, the carbon dioxide concentration determination processing unit 410, humidity determination processing unit 411, and temperature determination processing unit 412, which make decisions on whether or not to switch the ventilation means 3 to a ventilation state, can have their execution order set and their priority determined. Therefore, multiple determination processing units can be executed in an order that is important for preparing the cultivation room 2, which is the cultivation environment. Accordingly, the plant cultivation equipment 1 can achieve the excellent effect of making it easier to adjust its operation to the cultivation environment.

[0118] Furthermore, when the plant cultivation equipment 1's judgment command unit 42 operates in multi-mode, it becomes possible to switch between multiple judgment set information, each having different settings for at least one of the execution target information or execution priority information. This allows the judgment set information to be switched according to changes in the cultivation environment, thereby changing the execution target and execution priority, and making it easier to adapt the operation to the cultivation environment.

[0119] Furthermore, when the judgment command unit 42 of the plant cultivation equipment 1 operates in free mode, the set setting unit 441 can freely set the execution target information and execution priority information to create judgment set information, making it easier to adapt the operation to the cultivation environment.

[0120] It should be noted that the plant cultivation equipment according to the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0121] In the above embodiment, the growing room 2 was installed indoors (in the air-conditioned room 50 within the building 5), but the configuration is not limited to this. For example, the growing room 2 may be installed outdoors. In this case, when the ventilation means 3 is switched to the ventilation state, the air inside the growing room 2 is replaced with the unconditioned air from outside.

[0122] In the ventilation means 3 of the above embodiment, the ventilation drive unit 32 was attached to the exhaust passage 30 of the two air supply passages 31, but the configuration is not limited to this. For example, the ventilation drive unit 32 may be attached to the air supply passage 31 of the two air supply passages 31, or the ventilation drive unit 32 may be attached to both the exhaust passage 30 and the air supply passage 31.

[0123] Although the ventilation means 3 in the above embodiment was configured to have a ventilation drive unit 32 for creating airflow, it is not limited to this configuration. The ventilation means 3 may, for example, not have a ventilation drive unit 32 and may be configured to open and close an exhaust passage 30 and a supply passage 31, as long as it can replace the air inside the growing room 2 with the air outside the growing room 2.

[0124] The plant cultivation equipment 1 in the above embodiment was configured to operate in three operating modes: single mode, multi-mode, and free mode, but is not limited to this configuration. For example, the plant cultivation equipment 1 may be configured to operate in only one of the following operating modes: single mode, multi-mode, and free mode, or it may be configured to operate in two of the following operating modes: single mode, multi-mode, and free mode.

[0125] Although the multimode in the above embodiment was composed of three decision set information D4s, it may also be composed of, for example, two decision set information D4s or four or more decision set information D4s. In other words, the multimode only needs to be composed of multiple decision set information D4s.

[0126] Although not specifically mentioned in the description of the plant cultivation equipment 1 in the above embodiment, the switching of the judgment set information D4 when operating in multi-mode may be performed automatically, for example, based on the date, or a person may manually perform the switching operation.

[0127] Although not specifically mentioned in the description of the plant cultivation equipment 1 of the above embodiment, the judgment set information used in single mode may be configured so that the manufacturer can set the execution target information and execution priority information during manufacturing, or so that the administrator can set the execution target information and execution priority information during maintenance. In this case, the set setting unit 441 should be configured to have a management setting unit that allows persons with authority, such as the manufacturer or administrator, to set the execution target information and execution priority information.

[0128] Although not specifically mentioned in the description of the plant cultivation equipment 1 of the above embodiment, the execution target information of the judgment set information may be set to indicate two judgment processing units. In other words, there may be two execution targets.

[0129] Although not specifically mentioned in the description of the operation of the plant cultivation equipment 1 in the above embodiment, if the judgment command unit 42 is configured to perform judgment processing while recording the judgment processing unit that has executed it, the judgment command unit 42 may be configured to reset the record of the judgment processing unit when it receives an inappropriate notification from the judgment processing unit or when it has finished executing all judgment processing units.
