Description

Temperature and humidity control device {a control device of the temperature and humidity}

The present invention relates to measuring and controlling the temperature and humidity required for crop cultivation.

Temperature and humidity can be measured, controlled, displayed and alerted by a single controller.

In the facilities for growing conventional crops, there is a significant influence on the growth of crops by means of controlling temperature and humidity, among the essential ones. It is not necessary to explain that several new sensors are being developed for temperature measurement. Therefore, in the present invention, it is intended to quantitatively measure the humidity, and the problem caused by the change over time in the conventional measurement, and the price and precision are problems.

The present invention is to solve the above problems by replacing the temperature measurement with an electronic temperature sensor by using the principle of the conventional wet-drying method of the conventional humidity measurement method configured to provide a relatively accurate humidity while measuring will be.

To this end, the present invention applies the conventional principle as it is, except for using an electronic sensor instead of the conventional wet bulb system and dry bulb system, a water tank is installed under the electronic wet bulb temperature sensor, the water is pulled out of the water tank electronic wet bulb temperature When evaporating from the sensor, the temperature of the wet bulb temperature sensor is lowered due to the heat of evaporation, and a piece of cloth is connected between the bucket and the wet bulb temperature sensor. Also, the water bottle is provided with a stopper for replenishing water to supply water at any time In the vicinity of the electronic wet bulb temperature sensor and the electronic dry bulb temperature sensor, a barrier wall is installed so as not to be affected by direct sunlight or direct wind flow from the outside, and the electronic dry bulb temperature sensor is exposed to ambient temperature in the barrier wall. It is. Therefore, the temperature of the wet bulb temperature sensor wrapped with cloth is lower than the temperature of the dry bulb temperature sensor due to cooling caused by evaporation of water supplied by the cloth, and the humidity obtained by configuring humidity to be measured using the temperature difference between the two thermometers. As much and less of it is possible to check and display the humidity even at a place away from the site, and by using a microcomputer to control remotely it can facilitate the supply of water for crops.

Since it is configured as described above, the temperature difference between the temperature of the wet bulb temperature sensor and the dry bulb temperature sensor can be accurately understood by using a microcomputer. Through this, the current temperature and humidity are displayed on the display window. It is a useful invention that can be operated scientifically convenient for crop cultivation by being able to remotely control operations such as water supply.

The present invention will be described in detail with reference to the accompanying drawings.

Since it is the same structure as mentioned above, the electronic wet bulb temperature sensor 4 (hereinafter, abbreviated as "wet bulb sensor") in the windshield 5 is sealed by the heat of evaporation of moisture supplied from the water container 7 by the cloth 6. I) Lower than the temperature and the electronic dry bulb temperature sensor 10 (hereinafter abbreviated as "dry bulb sensor") is to detect the actual temperature is generated a temperature difference detected with the wet bulb and dry bulb sensor. By measuring the temperature, the relative humidity of the atmosphere can be obtained by using the humidity conversion table stored in the block diagram shown in FIG. 2 as a block diagram in FIG. 2, and the humidification or dehumidification can be performed by driving the relay in comparison with the set humidity. . At this time, the temperature in the space can be already obtained through the dry bulb temperature sensor 10, so that the temperature can be controlled by driving a relay in comparison with the set temperature value, and at this time, an alarm position related to high temperature, low temperature, high humidity, and low humidity. You can also generate an alarm by comparing with the setting value for.

That is, the outputs of the wet and dry bulb sensors 4 and 10 transmitted through the connector 11 of FIG. 1 are connected to the terminal T1 and the terminal T2 of FIG. 2, respectively, through the transducers R / V.
