However, in one independent control device using a computer, connecting all the measurement devices and control devices in the greenhouse and controlling them centrally with this control device has the following problems. That is,
(1) Many configurations of control devices and measuring devices installed in a greenhouse are required depending on factors such as the type of plant to be cultivated, the structure and scale of the greenhouse, and the like. The development of a centralized control device that centrally controls all environmental factors corresponding to such many configurations is costly in terms of program design and the like.
(2) The central control type control device is only installed one by one in the greenhouse of the building, so there is little demand, and therefore, mass production effects are difficult to appear and the cost is increased accordingly.
(3) Even when introducing into a greenhouse in which only a few control devices and measurement devices are installed, this expensive single control device is necessary, which is very expensive.
(4) When a central control type control device breaks down, the influence spreads over the entire environmental control in the greenhouse.

Due to such problems, an environmental control system using a computer has been introduced with a little less than 1% of the installation area of a greenhouse in Japan, and there is a problem that the diffusion rate is very low. Also, in the current agricultural field, the profit per unit area is bad, and luxury products with high unit prices are handmade and carefully cultivated, whereas labor-saving and efficiently cultivated plants have lower unit prices, When cultivating such cheap plants, there is a problem that the profit cannot be achieved unless the cost is further reduced compared to other fields.

  1 and 2, the environmental control device 1 includes a greenhouse 2 for cultivating horticultural crops such as vegetables, fruits and flowers, as well as the temperature inside and outside the greenhouse 2, including the temperature inside and outside the greenhouse 2.

And a computer 7 for monitoring the operation status.

  The computer 7 stores the data of the operation status of the input / output unit including the past history as data of the operation status of the setting means 3 in a memory (not shown). This computer 7 transmits the setting value data of the environmental factors, the date / time data from the clock, and the stored operation status data of the setting means 3 via the information communication network 6 to the control means 5 or a computer described later. The data of the operating status of the setting means 3 can be transmitted to the control means 5 and the computer 10 described later via the information communication network 6.

The situation data can be transmitted to the control means 5 and the computer 10 described later via the information communication network 6.

  In this embodiment, the computer 8 uses a board of a built-in computer similar to the computer 7 and is incorporated in the measuring means 4. This embedded computer board includes an interface with a measuring instrument controlled by the computer 8, an interface for exchanging necessary information with other means via the information communication network 6, and a past history. And a sufficient memory for storing data of the measured values and the operating status of the measuring means 4.

  The environment control device 1 is configured by at least one measuring means 4. The number of the measuring means 4 increases or decreases depending on the size of the greenhouse 2 and the introduction status of the environmental control device 1. The introduction status of the environmental control device 1 indicates how many types of measuring devices and control devices are used. That is, the type of the measuring device used by the measuring means 4 is determined depending on what environmental factors are measured. For example, a measuring device that measures temperature is a temperature sensor, a measuring device that measures humidity is a hygrometer, and a measuring device that measures the amount of solar radiation is a pyranometer. For example, the number of measuring means 4 increases or decreases depending on how many of these three types of measuring devices are used, such as three temperature sensors, one hygrometer, and two pyranometers.

There are many types of measuring equipment used in the measuring means 4, such as a temperature sensor, a pyranometer, a hygrometer, a rain gauge, a soil moisture sensor, a CO ₂ gas sensor, and at least one environment among many environmental factors. Factors can be measured.

  The control means 5 (5a, 5b, 5c...) Includes one control device (not shown) that can affect at least one of the many environmental factors, and the control device 5 It comprises a computer 9 (9a, 9b, 9c...) That performs control and monitoring of the operation status.

  The computer 9 controls the information necessary for controlling the control device via the information communication network 6 to control the same environmental factors as the setting means 3 and the measuring means 4 and other control factors that are closely related to each other. The control device is obtained from the means 5 and the control device is controlled based on the obtained information, and the operation status of the control device is stored in a memory (not shown) including the past history. Further, the computer 9 reads the stored operation status data of the control device via the information communication network 6 as the operation status data of its own control means 5 from the computer 10 or other control means 5. Can be sent according. The other control means 5 refers to control means 5 other than the control means 5 controlled by the computer 9.

  Further, the computer 9 can transmit or receive a control command to the other control means 5 with the other control means 5 via the information communication network 6, and this transmitted or received control command Thus, the control devices included in the control means 5 can be controlled or controlled with each other.

  In this embodiment, the computer 9 uses an embedded computer board similar to the computer 7 and is incorporated in the control means 5. This embedded computer board includes an interface with a control device controlled by the computer 9, an interface for exchanging necessary information with each other means via the information communication network 6, and a past history. And a sufficient memory for storing the data of the operation status of the control device.

  The environment control device 1 is configured by at least one control means 5. The number of the control means 5 increases or decreases depending on the scale of the greenhouse 2 and the introduction status of the environment control device 1. That is, the type of the control device used by the control means 5 is determined by the environmental factors to be controlled. For example, in this greenhouse, the environmental factor to be controlled is temperature, and there are various types of control devices for controlling this temperature, such as air conditioners, skylight devices, and ventilation fans. The number of the control means 5 increases or decreases depending on how many of these control devices are used, such as two air conditioners, one skylight device, and three ventilation fans.

  There are many types of control devices used in the control means 5, such as a cooling device, a skylight device, a side window hoisting device, a heating device, a ventilation fan, a light shielding curtain, and a supplementary lamp. Each control device can affect at least one of the many environmental factors.

  For example, taking an auxiliary lamp as an example, lighting the auxiliary lamp increases the light intensity in the greenhouse 2 and increases the temperature. Moreover, if the plant in the greenhouse 2 has a carbon dioxide concentration sufficient for photosynthesis and the plant has not sufficiently photo-synthesized, the plant performs photo-synthesis by increasing the light intensity. Then, the carbon dioxide concentration in the greenhouse 2 decreases because the plant performs photosynthesis. Therefore, the supplementary lamp can influence these environmental factors.

  The information communication network 6 couples the setting unit 3, all the measurement units 4, and all the control units 5. That is, the computers included in each means are connected (between the computer 7, all the computers 8, and all the computers 9).

  In this embodiment, LAN is used as the information communication network 6, TCP / IP is used as the communication protocol, and the computers are connected by star connection using HUB. However, the information communication network 6 is not limited to this, and any information communication network 6 may be used as long as the information communication network 6 is connected through a communication path capable of interacting with any device on the network.

  An information collecting computer 10 is further coupled to the information communication network 6. The computer 10 acquires data from the computer 7, the computer 8, and the computer 9 through the information communication network 6, and collects information on and monitors the operation status of the entire environment control device 1. Here, the computer 10 acquires the setting values of all the environmental factors set by the setting unit 3 and the operation status of the setting unit 3 from the computer 7, and the measured values acquired by the measuring unit 4 from the computer 8. And the operating status of the measuring device possessed by the measuring means 4 and the operating status of the controlling device possessed by the controlling means 5 are obtained from the computer 9. In this embodiment, the computer 10 uses an existing laptop computer that is commercially available.

  In this embodiment, the communication between the computers performed via the information communication network 6 is performed using XML format data. Therefore, the computer 10 does not need to use special software and is assigned to each computer. By simply designating an IP address and using a general web browser, it is possible to easily acquire setting values, measurement values, and operation status data.

  Next, the operation will be described. In the present invention, the computers 9 (9a, 9b, 9c...) Provided in all the control means 5 (5a, 5b, 5c...) Control the control equipment provided in each control means 5. In order to do this, information necessary for the control is acquired from the computer 7 of the setting unit 3, the computer 8 of the measuring unit 4 and the computer 9 of the other control unit 5 through the information communication network 6, respectively. Control devices included in each control means 5 are controlled independently.

  Further, the computer 9 transmits a control command to the computer 9 of the other control means 5 via the information communication network 6 when necessary to control the control devices of the control means 5 of the computer 9. It is involved in the control of the control equipment of other control means 5.

  In this way, all the control means 5 coupled by the information communication network 6 autonomously control the respective environmental factors and integrate these controls, so that the environment in the greenhouse 2 as a whole is controlled. Control factors in a complex way.

  However, the number and types of control procedures performed by the control means 5 controlled by these computers 9 vary depending on the scale of the greenhouse 2 and the combination of the measurement means 4 and the control means 5. Therefore, in this embodiment, the measuring device and the control device are a temperature sensor that measures the temperature outside the greenhouse 2, a temperature sensor that measures the temperature inside the greenhouse 2, a pyranometer installed in the greenhouse 2, and the skylight of the greenhouse 2. The temperature control in the greenhouse 2 by the air conditioner will be described in detail with reference to FIGS. 2 and 3 only when the skylight device and the air conditioner are opened and closed.

  In FIG. 2, the measuring means 4a is a temperature sensor for measuring the temperature in the greenhouse 2, and has a built-in computer 8a. The measuring means 4b is a temperature sensor for measuring the temperature outside the greenhouse 2, and includes a computer 8b. Similarly, the measuring means 4c is a pyranometer that measures the amount of solar radiation in the greenhouse 2, and includes a computer 8c. The control means 5a is a cooling machine that cools the inside of the greenhouse 2, and includes a computer 9a. Similarly, the control means 5b is a skylight device that ventilates the greenhouse 2 by opening and closing the skylight provided in the greenhouse 2, and includes a computer 9b.

First, as an initial setting, the setting means 3 sets how many times the temperature in the greenhouse 2 should be maintained (hereinafter referred to as a set value). Next, the rate of temperature rise and the temperature difference condition value in the greenhouse 2 relative to the amount of solar radiation (cal / cm ² ) in the greenhouse 2 are set. Here, the temperature difference condition value satisfies the condition that when the temperature in the greenhouse 2 measured by the temperature sensor 4a exceeds the set value, the cooling unit 5a starts cooling in the greenhouse 2a. This refers to the temperature difference (that is, measured value−set value).

Next, the operation will be described with reference to FIGS.
First, the computer 9a which the air conditioner 5a has acquires the measured value of the temperature in the greenhouse 2 measured by the temperature sensor 4a via the information communication network 6 from the computer 8a which the temperature sensor 4a has (step 21), and then continues. Then, the set value of the temperature in the greenhouse 2 set by the setting means 3 is obtained in the same manner from the computer 7 of the setting means 3 (step 22).

  Next, the measured value of the temperature in the greenhouse 2 is compared with the set value (step 23). As a result, if the temperature difference between the temperatures in the greenhouse 2 (ie, the measured value−the set value) <the temperature difference condition value, the cooling is not performed (step 24). At this time, the computer 9a included in the air conditioner 5a acquires the operation status of the air conditioner 5a, and if the air conditioner 5a is operating, stops the operation (step 24).

  When the temperature difference of the temperature in the greenhouse 2 (that is, the measured value−the set value) ≧ the temperature difference condition value, the computer 9a included in the air conditioner 5a has the greenhouse measured by the temperature sensor 4b via the information communication network 6. The measured value of the temperature outside 2 is obtained from the computer 8b of the temperature sensor 4b (step 25). Subsequently, the measured value of the amount of solar radiation in the greenhouse 2 measured by the pyranometer 4c is stored in the computer of the pyranometer 4c. The same is obtained from 8c (step 26).

The solar radiation condition value is calculated from the measured value of the solar radiation in the greenhouse 2 and the rate of increase in the temperature in the greenhouse 2 relative to the initial solar radiation (cal / cm ² ) set in the initial setting. The Here, the solar radiation amount condition value refers to an increase in temperature in the greenhouse 2 due to the amount of solar radiation in the greenhouse 2 (hereinafter referred to as the solar radiation amount condition). Next, the set value of the temperature inside the greenhouse 2 set by the setting means 3 is compared with the measured value of the temperature outside the greenhouse 2 (step 27).

  As a result, in the case of (the set value in the greenhouse 2−the temperature outside the greenhouse 2) ≧ the solar radiation amount condition value, the cooling effect in the greenhouse 2 by the outside air can be achieved by opening the skylight without operating the air conditioner 5a. Can be expected.

  Therefore, in such a case, the computer 9a included in the air conditioner 5a has the operation status of the skylight device 5b via the information communication network 6, that is, the information on how much the skylight is open, in the skylight device 5b. Obtained from the computer 9b (step 28), if the skylight is closed, a control command for opening the skylight is transmitted to the computer 9b of the skylight device 5b, and the computer 9b of the skylight device 5b controls the skylight device. The skylight is opened by interference (step 29), and the cooling is not performed (step 24). At this time, the computer 9a included in the air conditioner 5a acquires the operation status of the air conditioner 5a, and if the air conditioner 5a is operating, stops the operation (step 24).

  On the other hand, when the setting value in the greenhouse 2-the temperature outside the greenhouse 2 <the solar radiation amount condition value, such as when the sunlight is strong or the temperature outside the greenhouse 2 is not so low compared to the inside of the greenhouse 2 Even if the skylight is opened, the cooling effect in the greenhouse 2 by outside air cannot be expected.

  Therefore, in such a case, the computer 9a included in the air conditioner 5a has the operation status of the skylight device 5b via the information communication network 6, that is, the information on how much the skylight is open, in the skylight device 5b. Obtained from the computer 9b (step 30), if the skylight is open, a control command for closing the skylight is transmitted to the computer 9b of the skylight device 5b, and the computer 9b of the skylight device 5b controls the skylight device. The skylight is closed due to interference (step 31), and air conditioning is performed (step 32). At this time, the computer 9a included in the air conditioner 5a acquires the operation status of the air conditioner 5a. If the air conditioner 5a is not cooled, it cools (step 32).

  Since it is configured in this manner, information can be exchanged between the control means and the measurement means, and the control efficiency is improved. Furthermore, even if one of the control means fails, the failure does not spread to the entire apparatus, so that the entire apparatus is resistant to failure. In addition, since each control means performs control autonomously, if one of the control means fails, even if the failed control means is repaired or replaced with a new control means, It can be easily replaced with a temporarily used control means or a new control means. In addition, since the measuring means and the control means can be introduced in stages, the initial investment can be suppressed, and the addition, replacement, and replacement of existing facilities are easy.

  The environmental control device according to the present invention controls the environmental factors in the greenhouse independently by each control means, so that the number of measurement means and control means can be variously configured. It can handle a wide range of greenhouses. Measurement means and control means can be added and can be introduced in stages, so it can be introduced in stages not only when newly installing this device, but also when replacing existing equipment. This is especially suitable when you want to reduce the initial investment. In addition, replacement and expansion can be easily handled.
