In other words, the carbon dioxide is set to 0 ppm and the illuminance is set to OFF state throughout the day. When the seeding period is completed for 5 days, the next day, the slaughterhouse information module is activated to control the plant plant control system. And since it is necessary to carry out manual planting by 1 ~ 2 days before the end of the slaughterhouse, it will be notified to the administrator by SMS or the like that planting work is necessary.

Thus, by dividing a series of crop growth into a plurality of stages, unnecessary energy consumption can be reduced and the efficiency of growth can be improved by changing the composition of time and environment necessary for each step.

The operation processing unit 320 analyzes the growth model information 210 extracted by the information extracting unit 310 and assigns ranks to the plurality of information modules 211 in a time series sequence in cultivating the crops.

The operation processing unit 320 analyzes each information module 211 and determines whether the information module 211 includes environmental control information or manual operation information. At this time, a complex control signal corresponding to each environmental control information is output to the information module 211 including environmental control information through a predetermined operation program. This control signal is utilized as data for controlling the environment of the cultivation facility 500 described below.

The comparison and analysis unit 330 receives environmental information in the cultivation facility 500 from a collection sensor provided in the cultivation facility 500 to measure various environmental factors, 500 and the environment control information of the information module 211 transmitted to the operation processing unit 320 are compared and analyzed.

That is, when the environmental information such as temperature, humidity, and illumination in the cultivation facility 500 is greater than environmental control information such as temperature, humidity, and illumination pre-stored in the information module 211, The control unit 320 stops the control signal output from the processing unit 320 and outputs the control signal of the arithmetic processing unit 320 again.

The transceiver 340 provides a wired and wireless communication network when the central processing unit 300 and the control unit 400 communicate with each other.

As described above, the central processing unit 300 assigns rankings to the plurality of information modules 211 constituting the growth model information 210 according to the time-series sequence of crop growth.

The control module 211 activates the information module 211 sequentially according to the ranking of the information module 211 and outputs a control signal for the environment control information stored in the information module 211. At this time, If manual operation information is included, manual operation information is output through the user interface 100. When the manual operation is completed, a control signal according to the next information module 211 is output, thereby automating the growth of the crop .

The control unit 400 receives the control signal output from the central processing unit 300 and generates the environment of the cultivation facility 500 according to the growth period of the crop And control is performed step by step.
