Description

{Growth environment measurement device}

The present invention relates to an apparatus for measuring a growth environment.

Generally, a frequency band capable of radio communication (RF communication) uses 400 MHz band of UHF band and has a communication distance of 3 km on a flat basis. In recent years, a mobile device has been used by incorporating a modem using a frequency of 3 GHz band, and it performs communication between subscribers using a communication network via an ISP (Internet Service Provider) base station.

In addition, although a technology for connecting the main body and the terminal in a wireless manner and using the main body in a wired connection is disclosed in Japanese Patent Application Laid-Open No. 2000-0047190, it has an advantage of enabling wireless communication in a short distance from a wired communication, There is a drawback that can not be.

In addition, although a technology capable of transmitting and receiving digital data is disclosed in Korean Patent Laid-open Publication No. 10-2005-0124852, it is possible to transmit and receive a video image by a radio.

A domestic environment monitoring and control apparatus for a vinyl house growth environment using a multi-point sensor has been developed as a domestic patent registration No. 10-1269650, and includes a local device, a first measurement unit connected to a local device by a wire, A central remote controller for storing measured values of the device and the main device, and a mobile remote controller for giving a control command to the central remote controller. However, it is troublesome to connect the sensor to the wired line, and since the installation position of the sensor is different depending on the user, many sensors must be installed.

In addition, although a greenhouse management method using a gateway device using a mobile communication modem and a wireless local area communication module has been developed in Korean Patent Laid-Open No. 10-2008-0110941, it is suitable for a small greenhouse and is equipped with a mobile communication module and a wireless LAN module A gateway device and a sensor with a wireless local node module and control the greenhouse automation device by receiving data from a short distance wirelessly. Since the wireless method is a control method based on short distance wireless communication such as ZigBee and Bluetooth, However, since the measured values of the data do not represent the entire condition of the greenhouse, the entire greenhouse is controlled based on the growing conditions, and thus there is a disadvantage in that it can not provide an optimal greenhouse environment due to temperature variations.

=18이 된다. 따라서 공기수로부의 면적(c1)=a1-b1=28.53-18=10.53이된다. (c1/a1)×100=36.9%＜40%. 즉 40% 미만으로 면적이 줄어들어 공기가 이동하므로 속도가 빨라서 소음이 나고 측정값이 불안정하게 되어 식물생장환경 측정장치로 사용할 수 없는 문제점이 있다.In the meantime, a square sensor fuel package (PCB) is provided on the inner diameter portion of the multiple gas suction pipe portion to allow air to pass through the air channel portion which is a gap between the inside diameter and the square of the multiple gas suction pipe portion. 10-1115021, however, the intake air passing through the multiple gas suction pipe portion is blocked by the sensor housing and moves only to the air channel portion. For example, if the radius R1 of the multiple gas suction pipe portion is 3 cm, The cross sectional area (a1) is 3 x 3 x 3.14 = 28.53. Also, the area (b1)

= 18. Therefore, the area (c1) of the air channel portion = a1-b1 = 28.53-18 = 10.53. (c1 / a1) x 100 = 36.9% < 40%. That is, since the area is reduced to less than 40% and the air moves, the speed is high, the noise is generated, and the measurement value becomes unstable, which can not be used as a plant growth environment measuring device.

The commercial wireless communication modem 25 according to the present invention is a third-generation asynchronous mobile communication technology (3G, LTE, etc.), and the standard of communication technology is designated by the International Telecommunication Mobile Telecommunications-2000 (ITU). In 1999, ITU approved IMT-2000 as a high-speed wireless technology, the W-CDMA technology that developed GSM and the CDMA2000 technology that developed CDMA. The commercial wireless communication modem 25 is also based on Release 8, a wireless high-speed data packet access standard established in Dec. 2008 by the 3rd Generation Partnership Project (3GPP), and uses OFDM and MIMO, which are core technologies, 12 times faster communication speed. The download speed is up to 173Mbps (2x2 MIMO basis). Since the built-in eye address is obtained by subscribing to an Internet service provider network operator (for example, KT, SK Telecom, LG Yuplus, etc.), it is described as simply transmitting in two directions.

In the present invention, the 400 MHz band wireless module 26 (26a) performs RF communication through the 400 MHz band, so that the growth environment measuring device 100 and the sensing data transmitter 60 exchange data with each other. This is for the purpose of allowing data to be exchanged in a single space which is easy to install and has no limitation on the data transmission distance in response to the tendency of the house 50 becoming larger.

The measurement range of the CO ₂ sensor 32 in the present invention is preferably ~ 3000 ppm and -10 ° C to 50 ° C.

The temperature and humidity sensor 34 according to the present invention has a temperature range of -40 ° C to 124 ° C and a humidity range of 0 to 100%.

The temperature sensor 36 of the present invention has a measurement range of -40 ° C to 220 ° C.

The sensor mounting portion 14 of the present invention is provided with a sensor mounting portion 14 on the bottom of the sensor portion 30 provided at a position lower than the radial height of the suction fan 37 and the discharge fan 38, The free space portion 14a is extended in the width direction so as to facilitate the movement of the air without obstacles and further to have the extra space width W1 of the width larger than the diameter of the suction fan 37 and the discharge fan 38 By the same principle as Bernoulli's theorem, it reduces the velocity of the moving air.

The temperature and humidity sensor 34 and the temperature sensor 36 of the sensor unit 30 support the CO ₂ sensor 32 so that the horizontal positions thereof coincide with each other. If the radius R1 of the suction fan 37 is 3 cm as shown in FIG. 9, the cross sectional area e1 of the free space portion 14a due to the free space width w1, for example, Becomes w1 x 2r1 = 6w1. And the cross sectional area d1 of the fan portion of the housing 10 = 6 占 6 = 36. If the free space width w1 is, for example, 2 to 3, the cross sectional area e1 of the free space portion 14a becomes w1 x 2r1 = 6w1 = 12 to 18 and the cross sectional area d1 of the fan portion + (E1) = 48 to 54 of the cross section 14a. This is because the air introduced through the suction fan 37 is slowed down by Bernoulli's theorem and is moved at a slow speed to the sensor unit 30 in a sequential manner, Reduce errors and allow accurate sensing.

The suction air through the suction fan 37 and the discharge air amount through the discharge fan 38 move air in the growth space 51 at a constant air flow rate and at a wind speed so that the air can always be sensed based on fresh air.

Even if the internal humidity is not uniform, it is mixed with the rotation by the fan when sucked through the suction fan (37), thereby maintaining uniform humidity to enable accurate humidity sensing. Since the air sucked is discharged as much as it is sucked, the air is sensed based on the fresh air sucked from the outside of the housing 10 rather than the air remaining in the sensor installation portion 14, (14), it functions to recognize the whole uniform sensing value rather than the external local temperature condition.

4, a single growth environment measuring apparatus 100 is installed in a substantially central portion of the house 50, and the growth environment measurement window 100 is constructed as shown in FIGS. 1 and 2 So that the sensing value through the sensor unit 30 is recognized by the control unit 20 such as Mysy via the sensor interface 22. The control unit 20 converts the recognized sensing value into data in a predetermined format and transmits the data to the Internet service provider 70 through the commercial wireless communication modem 25 together with its own eye address. The Internet service provider 70 provides the communication network to the main server 40 composed of a mobile device or a computer. The main server 40 stores the standard values of the temperature and humidity of the crop and the season, compares the stored reference value with the received sensing value, and transmits the abnormality to the growth environment measuring apparatus 100. The growth environment measuring apparatus 100 Such as a hot air fan, a cooling fan, and a shoehorn, which operate wirelessly through the 400 MHz band wireless module 26, to perform a desired function. Such a command system may be selected by using different channels or different IDs. In this case, the corresponding command or sensing value may be displayed on the display 23. In addition, the power supply 27 for providing the constant voltage through the rectifier 27a may be used as the power supply required. The suction fan 37 and the discharge fan 38 are driven by the value of the fan driving unit 24 in accordance with the command of the control unit 20, .

Another example of use of the present invention is that when the one side of the growth space 51 of the house 50 is as large as a few hundred meters, the growth environment measuring apparatus 100 is arranged at the center as shown in FIG. 5, (60) is installed.

3, the sensing data transmitter 60 senses the value sensed by the sensor unit 30 of the CO ₂ sensor 32, the temperature / humidity sensor 34, and the temperature sensor 36 via the sensor interface 22 To the control unit (20). The control unit 20 drives the suction fan 37 and the discharge fan 38 to rotate at the same number of revolutions in the same specification through the fan drive unit 24 to improve the reliability of the sensed value, So that the moving speed of the air is relatively slowed so as to enable precise sensing and reduce the noise.

Of course, the driving power source functions to supply power through a power source 27 which functions as a constant voltage IC, which supplies a DC value through a rectifier 27a rectifying the AC power to a DC power source at a desired output value.

The control unit 20 operates in such a manner that the received sensing value is output to the display 23 such as a seventh segment or an LCD or the like and at the same time the sensing data is transmitted to the growth environment measuring apparatus 100 through the 400 MHz band wireless module 26a, Band wireless module 26 and the growth environment measuring device 100 transmits the control signal to the adjusting device 80 having the 400 MHz band wireless module through the 400 MHz band wireless module 26 based on the reference value to be determined by the self- Or may be provided to the main server 40 on the basis of the network use IP address of the Internet service provider 70 via its own commercial wireless communication modem 25, The control device 80 can be driven in the reverse order. It is preferable that the growth environment measuring device 100 is used to drive the regulating device 80 when only the single house 50 is used and when the plurality of houses 50 are installed in various areas, It is better to have control over.
