Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an environmental management device for plants, and particularly to a device that sets temperature and soil humidity ranges suitable for potted plants and issues an alarm when the set ranges are exceeded. It is something.

[Prior art]

Currently, there are a large number of types of plants, and due to their different habitats, they are particularly sensitive to environmental temperature and soil humidity.

Conventionally, environmental management for potted plants and other plants involves installing thermometers, checking the soil surface of pots by visually or touching them, determining the moisture level of the soil based on past experience, and turning on heating. I was putting it in and watering it. Therefore, this has to be done manually manually, which is time-consuming, and there are individual differences in the management, and people often forget to do this, and in some cases, the potted plants often die.

[Summary of the invention]

The present invention enables environmental management of plants to be easily performed by making it possible to know abnormalities in temperature or humidity using an alarm means.The present invention will be described in detail below using Examples.

[Embodiments of the invention]

FIGS. 1 and 2 are simplified configuration diagrams showing one embodiment of the environmental management device according to the present invention. In each figure, 1 is a management envelope, and this envelope 1 contains plants planted in pots 2. Plant 3 is installed. A temperature sensor is provided in the upper part of the pot 2, a humidity sensor 5 is buried in the soil of the pot 2, and each of these sensors 4,
Signals t and w corresponding to temperature and humidity from cable 6
．． 7 and the environmental management device main body 10 via jacks 8 and 9.
is supplied to a predetermined terminal 11 among the plurality of terminals provided. A power switch 12, an operation section 13, a buzzer 14, and a display device 15 are attached to the main body IO. Operation unit 1
3 is a temperature/humidity display selection section 18 consisting of a temperature display switch 16 and a humidity display switch 17; and an upper limit display switch 1.
9 and a lower limit display switch 20, a humidity upper and lower limit display selection section 24 consisting of an upper limit display switch 22 and a lower limit display switch 23, and a temperature setting change section consisting of an addition switch 25 and a subtraction switch 26. 27, and a humidity setting change section 30 consisting of an addition switch 28 and a subtraction switch 29.

31 is a memory, and the upper limit value nl of the management temperature.

Lower limit value 12, upper limit value m l of controlled humidity, lower limit value m2
The above values Nl, I22゜ml, m2
The value is adjusted so that it increases when the addition switch 25.28 is turned on and decreases when the subtraction switch 26.29 is turned on. Each value β1. A signal corresponding to #2°ml, m2 is input to the display device 15 via the selection switch circuit 32. The display device 15 displays the value selected by the selection switch circuit 32 as numerical data, character data, etc.

Signals from the temperature sensor 4 and humidity sensor 5 are supplied to a selection switch circuit 32. In addition, temperature display switch 1
6 and the temperature display switch 17 are supplied to a selection switch circuit 32.

The upper limit value Nl and lower limit value 12 of the control temperature are input to the comparator 33, and when the temperature t detected by the temperature sensor 4 rises by the upper limit value 7!1, the comparator 33 exceeds the lower limit value 12. When it falls, it outputs an H level signal and sounds the buzzer 14.

The upper limit (fiml, lower limit m2) of the above control humidity is determined by the comparator 3.
4, the comparator 34 outputs an H level signal and sounds the buzzer 14 when the humidity W detected by the humidity sensor 5 rises above the upper limit m1 and falls below the lower limit m2. . A comparator that operates like this can be constructed using a window type comparator.

In the above configuration, when the power switch 12 is turned on,
Each circuit works. Here, when the temperature t detected by the temperature sensor 4 deviates from the range of 11 and 12, the comparator 33 operates and sounds the buzzer 14, and the humidity W detected by the humidity sensor 5 becomes ml and m2. If it deviates from the range, the comparator 34 is activated and the buzzer 14 sounds. This allows the administrator to adjust the undisclosed temperature regulator in the management envelope 1 to maintain the temperature and humidity appropriately, or to adjust the humidity by supplying water. Protect plants by setting appropriate values. In addition, when performing this work, by operating the temperature display switch 16 or humidity display switch 17 and operating the selection switch circuit 32, the signals from the temperature sensor 4 and humidity sensor 5 are output to the display device 15. The temperature controller can be adjusted and water can be supplied while displaying the temperature and humidity.

Next, for example, when adjusting the upper limit value 7!1 of the management temperature, the upper limit display switch 19 of the selection section 21 is turned on. As a result, the selection switch circuit 32 selects the signal 11, and the display device 15 displays the upper limit value 7!1 of the controlled temperature. Here, by continuing to turn on the addition switch 25 while checking the upper limit value x1, a predetermined numerical value is added to the upper limit value 11, and by releasing the switch 25 at the predetermined value, the upper limit value is updated to a new value. Also, the lower limit value 1
2, by turning on the lower limit display switch 2o, the lower limit value ρ2 of the controlled temperature is displayed on the display device 15, and by keeping the subtraction switch 26 on while looking at this, the lower limit value 12 is decreased. , can be updated.

Also when updating the upper limit value ml and lower limit value m2 of the managed humidity, the lower limit display switch 22 and the upper limit display switch 2 of the selection section 24
3 and the setting change section 3o may be operated in the same manner.

[Effects of the Invention] As explained above, according to the plant environment management device according to the present invention, abnormalities in temperature or humidity are notified by the sound of an alarm buzzer, so that heating or water supply can be reliably adjusted. Furthermore, it is possible to eliminate individual differences in the amount of heating or water supply, which has the effect of facilitating environmental management of plants.
