Description

A kind of intelligent plant light compensation and audio stimulation growing system

Technical field

The utility model is related to a kind of intelligent plant light compensation and audio stimulation growing system, and user is by the system to planting The property of the light of thing light compensating lamp is controlled and appropriate audio stimulation is carried out to plant, can promote plant to a certain extent Growth.Belong to electronic technology field.

Background technology

Mode of agriculture based on greenhouse accounts for very big ratio in modern agriculture.This agricultural production can be with The state of the growing environment of plant is controlled in real time.Plant growing cycle, the quality of fruit are directly affected by growing environment.Close Suitable illumination is to promote one of necessary environmental factor of plant growth, therefore, improves the illumination of plant growth environment, is Modern Agriculture Industry improves one of productivity ratio, the scientific method for improving product quality.Weather and due to season, China some areas are a certain The solar irradiation of period is simultaneously unsatisfactory for demand of plant growth.For example, the rainy weather of summer, most of sleety weather in winter and Haze weather.During this period, solar irradiation greatly discount, it is impossible to meet plant demand.According to plant growth feature, plant exists The different phase of growth, the color of the light required for promotion plant growth（Wavelength）, intensity be different, this point is direct It has impact on the growth cycle of plant and the quality of fruit.In addition, plant is in addition to the demand to nutriment, also have to " essence The demand of god's life ", the regular oscillation of those interesting to listen to music sound waves of releiving so that the cellular elements in plant is also common therewith Shake, accelerate the metabolism of plant, so that plant growth accelerates to get up.From this, science to plant carry out light filling Audio signal stimulation is carried out to plant with appropriate, the production efficiency for improving agricultural is had great significance.Just at present, There is polytype light supplementing lamp for plants on the market, but these products are relatively simple, it is most of to be only suitable in certain plant Worked in the case of a certain growth phase, intensity of illumination can not be controlled, when needing quantity of light source more, be not easy to pipe Reason.In addition, the system for carrying out sonic stimulation to plant growth is also immature.In consideration of it, a kind of intelligence of the utility model design is planted Thing light filling and audio stimulation growing system.

The content of the invention

The utility model designs a kind of intelligent plant light compensation and audio stimulation growing system, including digital optical intensity is gathered in real time Module, power variable light source module, audio frequency control module, master controller.

Master controller is the core of the system, and as shown in Figure of description Fig. 1, system is by light intensity sensor and master control The real-time acquisition module of luminous intensity that device processed is built into, the variable power light source module of LED drivings and high-power LED light source, by controlling The audio-frequency module and master controller of device and MP3 module composition processed are constituted, modules after the power-up, centered on master controller " under leader ", work without any confusion realizes corresponding function.Fig. 1 is the general function figure of the system, can also be seen according to this figure To the system each several part composition, structure is distinct, reasonable the system each several part is described as follows：

（1）The real-time acquisition module of digital optical intensity

Fig. 2 is the real-time acquisition module work sheet of digital optical intensity.This module mainly uses model BH1750FVI digital light Intensity sensor.The communication interface of the sensor is I2C buses.I2C interfaces can complete wider under high-resolution working condition Investigative range（1- 65535 lx）；It has the spectral sensitivity characteristic close to human eye vision sensitivity；Illumination is completed on piece The numeral conversion of intensity is weaker to the dependence of light source（Incandescent lamp, white light LEDs, sunshine etc.）, and by Infrared jamming very Small, circuit system does not need any peripheral hardware.Sensor will receive luminous intensity after being converted into digital quantity, transfer to master controller Carry out respective handling.As shown in Figure of description Fig. 2.

（2）Power variable light source module

Fig. 3 power variable light source module work sheets, according to demand, this module provide six road variable colors, variable power Light source, by main controller control.It is due to the sunlight intensity in the factor of natural environment, plant growth environment due to a series of originals Because the intensity level needed in plant can not possibly be stablized.The function of this module is exactly that can be changed to mend according to the luminous intensity difference of environment The light intensity of light lamp.Power variable light source module is by high-power LED light source, LED driver group, into it is by main controller control, communication Mode uses CAN.LED driver is used to drive great power LED.The driver it is main by STM8S208R8 single-chip microcomputers, PT4115 constant-current drive circuits are constituted.Single-chip microcomputer receives the order of master controller, and 6 produced according to order by CAN Road PWM controls the output current of PT4115 constant-current drive circuits, and then controls LED brightness.Driven using constant-current drive circuit Caloric value when LED main cause is large-power LED light bead work is very big, and junction temperature is very high, and its equivalent resistance can be with temperature Change and change, then, want to allow its stabilized illumination, its electric current need to be made constant.The LED driver can drive six paths of LEDs, per road LED has 6 3W LED lamp bead, and is equipped with radiator per paths of LEDs.User can pass through main control according to the plant growth stage Man-machine interface circuit class in device selects LED mode of operation.As shown in Figure of description Fig. 3.

（3）Audio frequency control system

Music can promote plant growth to be the effect because sound stimulation.The rule of interesting to listen to music sound wave of releiving is shaken It is dynamic so that the cellular elements in plant also resonates therewith, the metabolism of plant is accelerated, and then promote to make plant growth. This part exports audio using MP3 audio processing chips.Same main controller control.Audio signal storage is in TF cards, side Just user can self-changeable audio file.

（4）Master controller

The interaction and communication of user and single-chip microcomputer is realized using matrix keyboard, so as to realize work of the user to the system each several part Operation mode is configured.The system employs the STM8S208R8 of ST Microelectronics as system master controller.The monolithic equipment There are CAN interface, I2C interfaces, UART interface, disclosure satisfy that the communication between modules and single-chip microcomputer in system, and Communication between controller and power variable light source module.

Embodiment：

After system electrification, operator selects appropriate pattern by the button on matrix keyboard.So-called selection mode is just It is the light source that different colours are selected according to the different growth phase of plant.

Determine after pattern, the work of the digital optical intensity real-time acquisition system that is connected with main controller, to the growing environment of plant Intensity of illumination is acquired.If environment illumination intensity is less than the light intensity required for plant, controller control light-source system is improved LED/light source luminous intensity.After environmental light intensity reaches the light intensity met, LED stable luminescences；If on the contrary, luminous intensity collection system System collects environmental light intensity higher than the light intensity required for plant, master controller reduction LED/light source luminous intensity, so as to enter to plant Capable suitably light filling.

Audion system can be controlled by matrix keyboard.User can select to play and stop to play music, can also control Make its volume.So that plant enjoys their " cultural life ".
