Abstract

The invention discloses a golden camellia seedling culture greenhouse control system, which comprises a central control unit, an illumination control system and a temperature control system, wherein the central control unit is respectively connected with the illumination control system and the temperature control system; the golden camellia seedling culture greenhouse control system also comprises an irrigation control system and a fertility supply system which are connected with the central control unit; the irrigation control system comprises an irrigation controller, an irrigation device and a plurality of humidity sensors arranged in a seedling culture plate, and the fertility supply system comprises a fertilizer preparation module and a fertilizer controller. The control system is applied to culture work of a golden camellia seedling culture greenhouse; moisture and illumination required in the golden camellia growth process can be monitored and controlled in real time, and the adopted fertility supply system is used for preparing and uniformly spraying nutrients required in the golden camellia seedling culture process through manual operation. Compared with the prior art, the golden camellia seedling culture greenhouse control system has the characteristics that the automation degree is high, the control is sensitive, the workload is greatly reduced, and in addition, the golden camellia seedling culturing quality can be ensured.

Example Embodiment

[0013] Such as figure 1 As shown, the golden flower tea seedling cultivation greenhouse control system includes a central controller, an illumination control system, and a temperature control system. The central controller is connected to the illumination control system and the temperature control system respectively, and also includes an irrigation control system connected to the central controller And fertility supply system. The data storage module of the central controller stores the reference values ​​of light intensity, temperature, and humidity required for different seedling process of Camellia sinensis. The values ​​collected by each sensor are compared with the reference values, and then each module is controlled to make corresponding action. among them
[0014] The irrigation control system includes an irrigation controller, an irrigation device, and a plurality of humidity sensors arranged in the seedling tray. The humidity sensor is connected to the input end of the irrigation controller, and the output end of the irrigation controller is connected to the irrigation device. The irrigation device may be a water pump connected to a water well, and the output end of the water pump is connected to a spraying device.
[0015] The fertility supply system includes a fertilizer preparation module and a fertilizer controller. The fertilizer preparation module includes a fertilizer mixing tank and a weighing system. The input end of the weighing system is connected to the fertilizer controller and the output end is connected to the inlet of the fertilizer tank. connection. When in use, the weighing system is equipped with a separate control switch. When the planting technician thinks it is necessary to fertilize the golden flower tea nursery, the control switch is activated, and then the fertilizer components are added to the weighing system, and the weighing system is configured to weigh Add the fertilizer to the mixing tank after the amount. The fertilizer mixing tank is also provided with a water inlet and a fertilizer liquid outlet, the water inlet is connected to the pool through a water pipe, and the water pipe is provided with a water control valve and a meter, and the amount of water added is controlled by the water control valve and the meter. Control the concentration of fertilizer solution. The fertilizer liquid outlet is connected to a movable spray head arranged on the inner side of the top of the greenhouse through a pipe. In this embodiment, in order to enable the spray head to move left and right, up and down to ensure uniform fertilization, the movable spray head is connected with a horizontal movement system and up and down movement System, the horizontal movement system and the up and down movement system are both connected with a driving device.
[0016] The illumination control system includes an illumination controller, an illumination sensor, a light supplement device and a roller shutter arranged on the outside of the top of the greenhouse. The illumination sensor is arranged above the bracket beside the seedling tray and is connected to the input end of the illumination controller. The output ends of the controller are respectively connected with the light supplement device and the roller shutter. In this embodiment, the light supplement device is a high pressure sodium lamp. When the light intensity is greater than the set reference value, the light controller controls the roller shutter to spread out and cover the outside of the greenhouse, so as to block the direct light from the light; when the light intensity is less than the set reference value, the light controller controls The roller shutter is retracted to allow direct light to enter the greenhouse, or when there is no sunlight at this time, the high-pressure sodium lamp is controlled to turn on to play a role in supplementing light.
[0017] The above are only preferred embodiments of the present invention. It should be pointed out that these examples are only used to illustrate the present invention without limiting the scope of the present invention. Moreover, after reading the content of the present invention, those skilled in the art Various changes or modifications can be made to the present invention, and these changes and improvements fall within the scope defined by the claims of the present invention.
