The present invention relates to an environment and growth information measurement system, and more specifically, while minimizing the number of environment and growth information measurement modules, it is possible to effectively detect and acquire a variety of information in a wide area and reduce installation and maintenance costs. It can be reduced, and its structure is simple and simple, so it can be easily installed and used in various places at low cost, and it can accurately and efficiently record environmental information of planting facilities and plant growth status without causing adverse effects on plant growth. It relates to an environmental and growth information measurement system that can be obtained.

In general, cultivation of crops was generally cultivated in the open land by selecting crops suitable for soil, climatic conditions, seasons, etc., but due to the climate characteristics of Korea, where the four seasons are distinct, crop cultivation in the open land is limited to a certain period of time, while people's income As the level rises day by day, demand for fresh agricultural products continues to be maintained throughout the year, and in recent years, uncertainty about domestic agricultural supply and demand and price fluctuations has increased due to frequent abnormal temperatures.

Accordingly, the facility horticulture industry is gradually expanding as a way to reduce uncertainty due to abnormal temperatures and to meet the annual demand of consumers, and various research and development are underway.

For example, facility horticulture planting crops on plantations constructed inside horticultural facilities such as glass greenhouses or plastic greenhouses, and performing cultivation processes while managing the environment to maintain conditions such as temperature, humidity, and CO ₂ ideal for planting. Is done.

To this end, a sensing device (hereinafter referred to as a 'sensing module') for measuring and collecting various information necessary for plant cultivation, such as temperature, humidity, CO ₂ concentration, and plant condition, is located inside the horticultural facility. Installed.

In addition, since the interior of the horticultural facility differs in temperature, humidity, and CO ₂ ratio depending on the location and height, each sensor must be installed and managed in order to cultivate effective crops, but since the sensing module is very expensive, it is practically applicable. It is impossible.

In addition, the conventional sensing module is a fixed type, and if it is to be installed elsewhere after installation in a certain place, additional removal and installation work is required, and only information at a specific location can be obtained in a fixed state, so the measured information is the entire greenhouse. There are limitations that cannot be used to represent areas and cannot be used as indicators that can indicate the characteristics of the entire greenhouse.

As a way to solve this problem, various research and development are in progress. For example, a "crop object monitoring system using a wire drone" disclosed in Korean Patent Publication No. 10-2016-0072519 has been proposed.

First, in the process of moving the measurement module frame 1 to a 3D spatial coordinate, when a 3D spatial coordinate value of a specific position to be moved is input, the target length of the cable 3 is derived by the winding device controller 5 Then, the length of the current cable 3 is compared with the target length to control the driving of the winding device driving part 4 to move the measurement module frame 1.

Looking at the movement process of the cable in more detail, as seen from the top view, the lengths of the four cables 3 located at the upper right, upper left, lower left, and lower right of the measurement module frame 1 are respectively l ₁ , l ₂ , l ₃ , In the case of l ₄ , the length calculation of the cables l ₁ , l ₂ , l ₃ , and l ₄ can be calculated by the following equations 1 to 4, and will be described with reference to FIGS. 7 to 10 of the accompanying drawings.

In the above equation, the horizontal, vertical, and height of the space (gardening facility, plant cultivation frame, etc.) of the cultivation facility h to which the measurement module frame 1 will move are called x _size , y _size , and z _size , respectively, and the measurement module frame 1 ) Is called x _module and y _module respectively, and the location of the measurement module frame 1 in spatial coordinates is called (x, y, z).

In addition, in FIG. 7 (top view), the (x, y, z) coordinates of the upper left are (0,0,0), and the coordinates of the lower right of FIG. 8 (front view) are (x _size , y _size , z _size ), And the coordinates of the position of the measurement module frame 1 are the center points of the horizontal and vertical lengths at the highest height (top surface). In addition, the change value of the cable length when the winding reel applied to the cable winding part 2 rotates once is called pir2.

On the other hand, in the environment and growth information measurement system according to the first embodiment of the present invention, when describing the return of the three-dimensional coordinates of the current position of the measurement module frame 1, the installation position is recorded as the current position during the initial installation, and the target position After moving the measurement module frame by entering the 3D spatial coordinates, record the target position as the current position if it operated normally without error. Using the current coordinates, the length of each cable 3 is derived and used for calculation to move the measurement module frame 1. The measurement module frame (1) is moved to the final target position by comparing the length of each cable required to be located at the target point and the length of the current cable and rotating the cable winding (2) to increase or decrease the length of the cable (3). Will be moved.

When there is an obstacle in movement due to an obstacle when the measurement module frame 1 moves, the length of the cable is adjusted in consideration of the location of the obstacle to avoid the obstacle and the movement process is performed. The avoidance of the obstacle predicts the point at which the cable is refracted by inputting the position of the obstacle in advance. As shown in FIG. 10, the cable length is adjusted in consideration of the refraction of the cable by the obstacle when moving in the height direction (z-axis).
