Abstract

The invention refers to a mobile camera with automatic control for the sprout-growth of vegetable seedlings in a compact arrangement, which includes a displacement and towage system, in which a high density of seedlings can be sprouted by square meter; the camera controls the temperature, the carbon dioxide levels, the hours of light, the humidity and the watering through a plurality of actuators connected to a PCB that houses the automatic control system, also maintaining a record of the controlled variables. The record is observed in the graphic interface in which, besides performing a monitoring in real time, also checks the climatic graphics of the camera.

Description

Mobile camera with automatic control for germination growth of vegetable seedlings TECHNICAL FIELD OF THE INVENTION.

The invention is found in the field of agriculture, specifically in horticulture as it relates to germination apparatuses, in addition to the heating technical sector and basic electronics for the control of climatic conditions within the chamber.

OBJECTIVE OF THE INVENTION.

The invention aims to provide the ideal conditions for the germination-growth of high quality vegetable seedlings with efficient use of time and space, by monitoring and real-time monitoring of the climatic conditions within the chamber automatically, as well as allowing the transport of the camera.

BACKGROUND.

To study the development of plants under controlled environmental conditions, growth chambers are used with climate control. Over time, the use of automatic control for seedling production and research has been explored, since it allows the management of variables such as temperature, humidity, carbon dioxide and light in the growth chambers. A set of technologies combine to achieve heating and cooling processes, for example the use of gas burners, heat exchangers, nebulizers and water sprinklers.

To achieve the optimum growth of the seedling it is necessary to strictly control the mentioned variables, which conventionally means a constant monitoring of the growth chamber. When the cameras are not automated, monitoring means investing in man-hours to control that the main environmental factors are kept within the ranges required by each plant.

Japanese patent WO2013 / 108332 A1"Plant growing device" describes a device with a ventilation unit comprising an inlet unit for taking in air in the growth chamber and an exhaust unit for the air leaving the chamber. The input unit has a port and a supply damper to open and close the feed port, a fan to send air in the direction of the growth chamber. The ventilation unit operates in inlet or outlet mode to enter or remove air from the growth chamber or a circulation mode through which air moves through the growth chamber. When switching between these modes, CO2 moves in the growth chamber. The gas density, temperature and humidity within the growth chamber can be uniform, and as a result, the growth efficiency of a plant can improve.

Chinese document 102914331 A "Portable agricultural environment parameter monitoring system base don wireless sensing" describes a monitor of agricultural environmental parameters based on wireless detection, the monitor comprises a sensor module, a radio frequency module, a display, a module power, microcontroller, alarm, a miniature printer and storage.

As can be seen in the review of the state of the art, there are devices that automate the control of the climatic agricultural variables necessary for the optimal growth of the seedlings, even there are small-scale systems designed for this purpose. The novelty of the invention presented is that it is a system with a capacity of approximately 10,000 seedlings that is portable, uses artificial light for the growth of the plastics and also has automatic control of temperature, humidity and carbon dioxide inside the chamber.

TECHNICAL PROBLEM TO BE RESOLVED.

Control the conditions of relative humidity, carbon dioxide, lighting and temperature in a growth chamber is key to achieving growth of good quality plants, in addition to an efficient use of time to optimize these conditions for the specifications of each species.

There are cameras of different sizes to achieve germination of seeds, but those suitable for large productions are large, while those of smaller sizes also have reduced capacity for seedlings. Additionally, if it is necessary to move the seedlings from one location to another, the mobility becomes inconvenient because the cameras have not been designed for these purposes. Removing the seedlings from the chamber alters its development or germination cycle.

DETAILED DESCRIPTION OF THE INVENTION.

The invention is a mobile camera with automatic control for the germination-growth of vegetable seedlings that has a system of wheels (12) and support for towing (13).

The control system starts by considering the disturbances in the system (1) to change the variable that is measured (2). The sensors (5) measuring temperature, relative humidity and carbon dioxide content are installed inside the growth chamber (4). Following the measurement, the data is acquired on a PC (6) and sent via wireless communication to the PC controller (7). The user will be able to interact with the controller through the user interface (3). The controller (7) sends signals to the power board (8) and activates the actuators (9), which will be fins, heaters, air conditioner, humidifier, dehumidifier, LED lamp and fan.

Finally the cycle returns to the change of measured variable (2) and starts again. The camera automatically controls the temperature, hours of light, humidity and CO2 inside the camera through a control system consisting of an interface (3) where the trend is monitored in real time. the behavior graphs of each variable.

It is capable of traveling along roads, which provides the possibility of transporting or transporting the seedlings to remote areas. The control system has day and night mode to change the weather conditions inside the camera. A history of the behavior of the seedlings is also maintained, which is maintained even when the control system is disconnected.

The chamber has capacity for two racks (11) on which the trays (10) are placed for seedling production. It also has an access door in the front (14).
