[0004] Incidentally, in the prior art described in Patent Document 1, as mentioned above, the temperature inside the greenhouse is adjusted by a temperature adjustment device, but this requires a large-scale capital investment.

[0005] In this regard, it is possible to reduce the increase in capital investment by manually opening and closing the greenhouse door without using a temperature control device. However, in this case, a device that notifies the greenhouse temperature to the worker in order to determine the timing to adjust the temperature inside the greenhouse is required, which requires capital investment.

[0006] In consideration of the above, the present invention aims to provide a temperature estimation system, a temperature estimation method, and a temperature estimation program that can notify the outside of the greenhouse of the temperature inside the greenhouse while suppressing an increase in capital investment required for this purpose.

[0011] According to the present invention as set forth in claim 2, the weather forecast information acquisition unit acquires weather forecast information. The greenhouse temperature estimation unit then inputs the predicted air temperature at a predetermined time obtained from the weather forecast information into a temperature estimation model as the temperature inside the vehicle, thereby predicting the scheduled time when the temperature inside the greenhouse will reach the predetermined temperature. Therefore, in this invention, the user of the greenhouse can perform various tasks on the greenhouse based on the scheduled time when the temperature inside the greenhouse will reach the predetermined temperature.

[0012] The temperature estimation system of the present invention described in claim 3 is an invention described in claim 1 or claim 2, further comprising a communication unit that is provided in the vehicle and is capable of transmitting temperature information about the interior of the vehicle cabin acquired by the temperature measurement unit to a mobile terminal, and the greenhouse temperature estimation unit is provided in the mobile terminal.

Meanwhile, the mobile terminal is provided with a greenhouse temperature estimation unit, and this greenhouse temperature estimation unit outputs estimated temperature information inside the greenhouse based on the temperature information inside the vehicle cabin transmitted from the vehicle side. Therefore, in this invention, the configuration on the vehicle side can be prevented from becoming complicated when obtaining estimated temperature information inside the greenhouse.

[0014] The temperature estimation system of the present invention described in claim 4 is an invention described in claim 1 or claim 2, in which the greenhouse temperature estimation unit is provided in the vehicle, and further includes a communication unit that is provided in the vehicle and is capable of transmitting the estimated temperature information to a mobile terminal.

[0015] According to the present invention as set forth in claim 4, the greenhouse temperature estimation unit and the communication unit are provided in the vehicle, and estimated temperature information output from the greenhouse temperature estimation unit is transmitted to the mobile terminal via the communication unit. Therefore, in the present invention, it is possible to prevent the configuration of the mobile terminal from becoming complicated when obtaining estimated temperature information inside the greenhouse.

[0016] The temperature estimation method of the present invention described in claim 5 measures the temperature inside the passenger compartment of a vehicle parked near a greenhouse, and estimates the temperature inside the greenhouse by inputting the temperature information inside the passenger compartment into a temperature estimation model based on the correlation between the temperature inside the passenger compartment and the temperature inside the greenhouse.

[0017] The temperature estimation program of the present invention described in claim 6 causes at least one processor to measure the temperature inside the passenger compartment of a vehicle parked near a greenhouse, and estimate the temperature inside the greenhouse by inputting the temperature information inside the passenger compartment into a temperature estimation model based on the correlation between the temperature inside the passenger compartment and the temperature inside the greenhouse.

[Figure 6] 10 is a flowchart showing a flow of processing by a mobile terminal in the temperature estimation system according to the present embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0020] An example of an embodiment of a temperature estimation system according to the present invention will be described below with reference to Figures 1 to 6. As shown in Figure 1, a "temperature estimation system 10" according to this embodiment includes a vehicle control device 12, an "interior thermometer 14" as a temperature measurement unit, and a "mobile terminal 16."

[0021] The vehicle control device 12 is mounted on a "vehicle 22" parked in a parking space 20 provided adjacent to a "vinyl greenhouse 18" which is an example of a greenhouse.

[0022] 2, the vehicle control device 12 includes a processor "CPU (Central Processing Unit)" 12A, a ROM (Read Only Memory) 12B, a RAM (Random Access Memory) 12C, a storage 12D, a communication I / F (Interface) 12E, and an input / output I / F 12F. The CPU 12A, the ROM 12B, the RAM 12C, the storage 12D, the communication I / F 12E, and the input / output I / F 12F are connected to each other via a bus 12G so as to be able to communicate with each other.

[0023] The CPU 12A is a central processing unit and is capable of executing various programs. Specifically, the CPU 12A reads programs from the ROM 12B and executes the programs using the RAM 12C as a work area. The CPU 12A reads and executes the execution programs stored in the ROM 12B, thereby enabling the vehicle control device 12 to perform various functions, as will be described later.

[0024] More specifically, the ROM 12B stores various programs and various data, while the RAM 12C serves as a work area and is capable of temporarily storing programs or data.

[0025] The storage 12D includes a hard disk drive (HDD) or a solid state drive (SSD) and is capable of storing various programs including an operating system and various data. The storage 12D is also capable of storing measurement results from the interior temperature gauge 14 and various specification information of the vehicle 22, as will be described later.

[0026] The communication I / F 12E is an interface used to connect the vehicle control device 12 to the network N. For this interface, a communication standard such as Ethernet (registered trademark), FDDI, or Wi-Fi (registered trademark) is used. The communication I / F 12E may also include a wireless device. The communication I / F 12E communicates with the mobile terminal 16 via the network N, thereby enabling transmission and reception of various information with the mobile terminal 16. The various information acquired from the mobile terminal 16 is stored in the storage 12D.

[0027] The input / output I / F 12F is an interface through which the vehicle control device 12 communicates with each device mounted on the vehicle 22. The vehicle control device 12 is connected to various devices described below via the input / output I / F 12F so as to be able to communicate with each other. Note that these devices may be directly connected to the bus 12G.

[0028] The devices connected to the input / output I / F 12F of the vehicle control device 12 include an interior thermometer 14. The interior thermometer 14 is capable of measuring the temperature inside the "compartment 22A" of the vehicle 22, and transmits a temperature signal based on this temperature to the vehicle control device 12. The storage 12D is configured to store time-series data of the temperature inside the compartment 22A.

[0029] Next, the functional configuration of the vehicle control device 12 will be described with reference to Fig. 4. The vehicle control device 12 functions as a collection of a "communication unit 24," a vehicle specification storage unit 26, and an interior temperature acquisition unit 28 by the CPU 12A reading and executing an execution program stored in the ROM 12B.

[0030] The communication unit 24 is capable of transmitting and receiving various information to and from the mobile terminal 16 via the network N.

[0031] The vehicle specification storage unit 26 stores vehicle specification information relating to the specifications of the vehicle 22. Specifically, the vehicle specification storage unit 26 stores the volume of the passenger compartment 22A and the area of ​​the openings of the vehicle 22, that is, the total area of ​​the front window, rear window, and side windows. When the communication unit 24 receives a request signal from the mobile terminal 16, the vehicle specification storage unit 26 transmits the vehicle specification information of the vehicle 22 to the mobile terminal 16 via the communication unit 24.

[0032] The interior temperature acquisition unit 28 acquires temperature information measured by the interior thermometer 14 and stores time-series data of the air temperature inside the vehicle interior 22A. When the communication unit 24 receives a request signal from the mobile terminal 16, the interior temperature acquisition unit 28 transmits the time-series data of the air temperature inside the vehicle interior 22A to the mobile terminal 16 via the communication unit 24.

[0033] Next, the configuration of the mobile terminal 16 will be described with reference to Fig. 3. The mobile terminal 16 is a terminal used by the user of the greenhouse 18 and the vehicle 22, and is configured to include a "CPU 16A" as a processor, ROM 16B, RAM 16C, storage 16D, and a communication I / F 16E. The CPU 16A, ROM 16B, RAM 16C, storage 16D, and communication I / F 16E are connected to each other via a bus 16F so as to be able to communicate with each other. The CPU 16A, ROM 16B, RAM 16C, storage 16D, and communication I / F 16E basically have the same functions as those constituting the vehicle control device 12 described above.

[0034] The storage 16D includes an eMMC (embedded multi media card) or a UFS (universal flash storage) and is capable of storing various programs and data, such as a temperature estimation model (to be described later). The execution programs stored in the ROM 16B are read and executed by the CPU 16A, enabling the mobile terminal 16 to perform various functions.

[0035] Specifically, a predetermined application software (hereinafter referred to as an app) is installed in the mobile terminal 16. When the user of the mobile terminal 16 starts up this app, the mobile terminal 16 functions as a collection of a communication unit 30, a greenhouse condition acquisition unit 32, a "weather forecast information acquisition unit 34," and a "greenhouse temperature estimation unit 36," as shown in FIG.

[0036] The communication unit 30 is capable of transmitting and receiving various information to and from the vehicle control device 12 and a data server (not shown) via the network N.

[0037] The greenhouse condition acquisition unit 32 is capable of acquiring greenhouse specification information relating to the specifications of the greenhouse 18 based on the user's operation of the mobile terminal 16. Specifically, the greenhouse condition acquisition unit 32 is capable of acquiring greenhouse specification information such as the volume of the greenhouse 18 and the materials (vinyl chloride, polyolefin film, etc.) that make up the greenhouse 18 through input by the user by displaying a predetermined operation screen to the user, and transmitting the acquired greenhouse specification information to the greenhouse temperature estimation unit 36.

[0038] The weather forecast information acquisition unit 34 is capable of acquiring weather forecast information from the data server, and is also capable of transmitting the acquired weather forecast information to the greenhouse temperature estimation unit 36 ​​.

[0039] The greenhouse temperature estimation unit 36 ​​is capable of acquiring vehicle specification information of the vehicle 22 from the vehicle specification storage unit 26 by transmitting a request signal to the vehicle specification storage unit 26 via the communication unit 30. The greenhouse temperature estimation unit 36 ​​is also capable of acquiring time series data of the air temperature inside the vehicle compartment 22A from the vehicle compartment temperature acquisition unit 28 by transmitting a request signal to the vehicle compartment temperature acquisition unit 28 via the communication unit 30.

[0040] The greenhouse temperature estimation unit 36 ​​inputs various information, including greenhouse specification information acquired from the greenhouse condition acquisition unit 32, vehicle specification information acquired from the vehicle specification memory unit 26, and time series data of the air temperature inside the vehicle compartment 22A acquired from the vehicle compartment temperature acquisition unit 28, into a temperature estimation model, and outputs the estimated temperature inside the current greenhouse 18 as estimated temperature information.

[0041] As an example, the temperature estimation model is a machine-learned model that is trained according to known machine learning techniques such as a recurrent neural network, using sets of greenhouse specification information for the greenhouse, vehicle specification information for the vehicle, time series data for the temperature inside the vehicle, and time series data for the temperature inside the greenhouse as training data for multiple combinations of various greenhouses and various vehicles parked near the greenhouses.

[0042] In addition, the greenhouse temperature estimation unit 36 ​​inputs time series data of the predicted temperature in the area where the greenhouse 18 is installed at a specified time, obtained from the weather forecast information acquisition unit 34, as time series data of the temperature inside the vehicle compartment 22A, thereby predicting the scheduled time when the temperature inside the greenhouse 18 will reach a specified temperature and outputting this scheduled time as estimated temperature information.

[0043] The greenhouse temperature estimation unit 36 ​​is configured to display the estimated temperature and the scheduled time output from the temperature estimation model on the display unit 16G of the mobile terminal 16.

[0044] (Actions and Effects of This Embodiment) Next, the operation and effects of this embodiment will be described.

[0045] An example of the control flow of the vehicle control device 12 will be described below mainly using the flowchart shown in FIG.

[0046] When this control flow starts, in step S100, the CPU 12A of the vehicle control device 12 transmits the vehicle specification information of the vehicle 22 to the mobile terminal 16 in response to a request signal from the mobile terminal 16.

[0047] In step S101, the CPU 12A transmits the time-series data of the air temperature inside the vehicle compartment 22A to the mobile terminal 16 in response to a request signal from the mobile terminal 16, and ends the control flow.

[0048] Next, an example of the control flow of the mobile terminal 16 will be described mainly using the flowchart shown in FIG.

[0049] In step S200, CPU 16A displays a predetermined operation screen for the user and acquires greenhouse specification information of greenhouse 18.

[0050] In step S201, CPU 16A acquires, from a data server, time-series data of predicted temperatures in the area where greenhouse 18 is installed.

[0051] In step S202, the CPU 16A acquires from the vehicle control device 12 the vehicle specification information and the time-series data of the temperature inside the vehicle compartment 22A.

[0052] In step S203, CPU 16A inputs the greenhouse specification information, vehicle specification information, and time-series data of the air temperature inside vehicle compartment 22A into the temperature estimation model, and outputs the current estimated temperature inside greenhouse 18 as estimated temperature information.

[0053] In step S204, CPU 16A inputs greenhouse specification information, vehicle specification information, and time series data of predicted temperatures in the area where greenhouse 18 is installed into a temperature estimation model, predicts the scheduled time when the temperature inside greenhouse 18 will reach a specified temperature, and ends the control flow.

[0054] Therefore, in this embodiment, estimated temperature information inside the greenhouse 18 can be output from the greenhouse temperature estimating unit 36 ​​to various devices such as the mobile terminal 16 without adding any equipment to the greenhouse 18.

[0055] Furthermore, in this embodiment, the greenhouse temperature estimation unit 36 ​​predicts the scheduled time when the temperature inside the greenhouse 18 will reach the specified temperature by inputting the predicted air temperature at the specified time obtained from weather forecast information into the temperature estimation model as the temperature inside the vehicle compartment 22A. Therefore, in this embodiment, the user of the greenhouse 18 can perform various tasks on the greenhouse 18 based on the scheduled time when the temperature inside the greenhouse 18 will reach the specified temperature.

[0056] Additionally, in this embodiment, a predetermined application is installed in the mobile terminal 16, and thus the mobile terminal 16 is provided with a greenhouse temperature estimation unit 36. Therefore, in this embodiment, when obtaining estimated temperature information inside the greenhouse 18, it is possible to prevent the configuration of the vehicle 22 from becoming complicated.

[0057] In this way, in this embodiment, the temperature inside the greenhouse 18 can be notified to the outside of the greenhouse 18, and an increase in capital investment for this purpose can be suppressed.

[0058] <Modification> Next, a modification of the above-described embodiment will be described.

[0059] This modified example has basically the same configuration as the above-described embodiment, but a weather forecast information acquisition unit 34 and a greenhouse temperature estimation unit 36 ​​are incorporated into the functional configuration of the vehicle control device 12.

[0060] With this configuration, estimated temperature information of the greenhouse 18 is transmitted from the vehicle control device 12 to the mobile terminal 16, so that the functional configuration of the mobile terminal 16 can be prevented from becoming complicated when obtaining estimated temperature information inside the greenhouse 18.
