Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device capable of automatically controlling and monitoring the indoor and ground temperatures in a nursery house.

[0002]

[Prior art]

 As a conventional technology, there is a nursery house in which a self-controlled heater is arranged between the nursery pot and the ground, which the present inventors have made. (Application on July 9, 1990, Patent application No. 181360 in 1990).

According to this invention, the seedlings at the ends in the nursery house can retain the temperature suitable for growth, like the seedlings in the center.

Further, when the room temperature of the nursery house is extremely lowered in winter, a hot water pipe or a hot air duct is provided in the nursery house in order to heat the room temperature of the nursery house.

[0005]

[Problems to be solved by the device]

 In the invention of the above-mentioned application, there is a problem that the ability to automatically detect the indoor and ground temperatures and the ability to lower the indoor temperature of the nursery house are inferior.

Further, the hot water pipe or hot air duct provided in the nursery house can achieve the purpose of heating when the temperature is low, but cannot be used when the room temperature becomes high. There was a problem.

When the room temperature of the nursery house becomes high, if the nursery house is made of vinyl, the hem of the vinyl curtain must be rolled manually, and at night again. Since the temperature drops, the bottom of the vinyl curtain must be lowered and the hot water pipe or the hot air duct must be operated if necessary, but this was done manually Was hard.

[0008] Furthermore, since the indoor temperature affects the growth of seedlings, in some cases the day may have to be monitored almost all day, and from this point as well, the labor is tremendous. There was a problem that the labor burden was great under the declining agricultural population and aging population.

Therefore, the present invention makes it possible to automatically control and monitor the room temperature and soil temperature in the nursery house even if the season becomes cold or warm, and thus the seedlings in the nursery house can be managed. The purpose is to reduce the labor of people involved in training.

[0010]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the automatic monitoring control device in the seedling raising house of the present invention is an automatic control device in the seedling raising house, in which the self-controlled heater is arranged between the seedling raising pot and the ground. The self-control type heater is connected to an automatic control device, and an indoor air temperature sensor, a ground temperature sensor and a forced ventilation device are further provided in the nursery house, and the indoor air temperature sensor, the soil temperature sensor and the forced ventilation device are automatically controlled. It consists of being connected to a device.

Further, it is preferable that an outside air temperature sensor, a heating device and / or a humidifying device are provided in the seedling raising house and are connected to the automatic control device.

Further, a circulation fan may be provided in the nursery house.

[0013]

[Action]

 The indoor air temperature sensor detects the temperature in the room and sends a signal to the automatic control device, and the ground temperature sensor detects the soil temperature and sends a signal to the automatic control device, and the automatic control device sends a signal from the sensor. It senses and sends a signal to the forced ventilation system and self-controlled heater to keep the room temperature and soil temperature of the nursery house at the set temperature, and operate them.

Further, the outside air temperature sensor, the heating device and / or the humidifying device are operated. Then, the circulation fan is operated as necessary.

The forced ventilation system consisting of a damper and a fan operated by an automatic control device works by the damper sucking the outside air and the fan sending out the indoor air to set the room temperature in the nursery house. It works to lower the temperature.

Further, the self-regulating heater operated by the automatic control device functions to raise the room temperature and the ground temperature to the set temperature.

Further, when the self-controlled heater cannot raise the room temperature sufficiently, the heating device works by the automatic control device to raise the room temperature to the set temperature, and the humidification device works by the automatic control device. The humidity of can be adjusted to the set humidity.

If an outdoor air temperature sensor is provided, the outdoor temperature can be sensed by the automatic control device, and the room temperature and ground temperature can be set and adjusted better.

Further, by operating the circulation fan, it is possible to average the temperature without stagnation of the air in the nursery house.
