Description
Technical Field
The invention relates to the technical field of plant water shortage detection and treatment, in particular to an intelligent plant water shortage protection system and method based on acoustic signals.
Background
Moisture is one of the important raw materials for plant photosynthesis, and plant moisture physiological studies show that: the phenomenon that plants transmit a signal of water shortage to the outside by using own 'language' is called as the 'sound emission' phenomenon of the plants. The phenomenon of plant sound production in the absence of water can be explained by the theory of moisture transport cohesion. It is believed that water is under a certain tension when transported in the soil-plant-atmosphere continuum, that tension increases when soil moisture is low, and that when it exceeds a certain limit, the continuum of water columns breaks or evacuates due to cohesive failure between water molecules or loss of effectiveness of adhesion to the walls of the conduits, which is a phenomenon of cavitation of the plant xylem. At the same time as the cavitation occurs, the tension release generates a shock wave, accompanied by the generation of an acoustic emission signal. The acoustic emission phenomenon of the plants is generated by the rupture of transpiration flow caused by water deficiency, so that the occurrence of Acoustic Emission (AE) events is closely related to the water deficiency condition of the plants, and the occurrence of the AE events can be used as a sensitive physiological index to guide plant watering. In actual life, plants are mostly irrigated according to personal experience, so that it is difficult to timely and accurately monitor physiological indexes of the plants and accurately judge the water shortage condition of the plants, and the situations of excessive watering or excessive water shortage often occur. On the other hand, plants are left unattended for some reasons such as work on a business trip or travel, etc., and do not avoid death of the plants due to excessive water shortage, and temporary plant protection devices are required to avoid death thereof.

All parameters in the system are continuously acquired for 24 hours, and the water stress period is taken as a test period for monitoring.
Fig. 4 is a flow chart of a main program of the system of the intelligent plant water shortage detection system based on the acoustic signal, and as shown in the figure, after passing through the a/D converter, the signals are all changed into digital signals and are transmitted to the STC89C52 single chip microcomputer, the judgment is carried out according to the acoustic emission signal STC89C52 single chip microcomputer, and a single-parameter analysis method is generally adopted for the analysis and evaluation of the acoustic emission signal. The system adopts a counting method to judge and process an Acoustic Emission (AE) signal. An acoustic emission event is a single burst-type signal generated by a local change in the material, and an acoustic emission count (ringing count) is the number of times the acoustic emission signal exceeds a certain set point. The number of times the signal exceeds the threshold in a unit time is the count rate, and the acoustic emission count rate is dependent on the response frequency of the sensor, the damping characteristics of the structure, and the level of the threshold for an acoustic emission event. The acoustic emission detected by the sensor is counted as
Wherein f is 0 Of the centre frequency of response of the sensor, beta being waveAttenuation coefficient, V p Is the peak voltage, V t Is the threshold voltage.
The incidence of Acoustic Emission (AE) events is strongly correlated with the intensity of the illumination, while temperature is also strongly correlated with the illumination. Therefore, the incidence rate of Acoustic Emission (AE) events can be used as a comprehensive water shortage indicator to judge whether the plants are in water shortage.
Plant water deficit rating Q is scored by the count of Acoustic Emission (AE) events occurring per second.
N is less than or equal to 4 when the number of acoustic emission counts per second is more than 2, Q is less than or equal to 'slight water shortage', and a lamp 3 and a lamp 4 are on;
if the acoustic emission count is more than 4 and less than or equal to 8, Q = 'moderate water shortage', and the lamp 2 and the lamp 4 are on;
acoustic emission count 8 < N, Q = "heavy water out", and lamps 1 and 4 are on.
Due to the difference in plant habits, they are roughly classified into three categories: the plants which like wet, ordinary and dry can be watered more, the plants which like wet can be watered less and the plants which like dry can be watered less, and the requirements on the humidity of the soil are different. The soil humidity sensor of the system can acquire the soil moisture condition in real time, and the soil moisture condition is analyzed by A/D conversion to the single chip microcomputer, the plant species cultivated by a user is preset in the single chip microcomputer in advance, and the preset value of the soil humidity is given according to the species. When the water shortage condition of the plant is judged according to the occurrence rate of the Acoustic Emission (AE) event, the corresponding LED is turned on, and when the soil humidity reaches the maximum value of the water required by the plant during watering, the lamp 4 is turned off and does not need watering.
The use method of the system comprises the following steps:
the user opens the intelligent protection system of plant water shortage based on acoustic signal, and acoustic signal (AE) sensor 2 and soil moisture sensor 4 begin work, gather real-time conditions cultivated in a pot, send acoustic signal when the plant water shortage, gather by acoustic signal (AE) sensor 2 to judge the analysis by the singlechip as signal analysis module, the LED lamp that corresponds when exceeding the settlement scope is bright, and the plant water shortage promptly reminds the user to need to water. The user begins to water, and soil moisture content begins to rise, and when exceeding the soil moisture value that predetermined heterogeneous plant is suitable, lamp 4 extinguishes, reminds the user to stop watering, and this is simple swift, convenient and practical to the user of experience of not watering undoubtedly.
Acoustic emission technology is a dynamic inspection method where the energy detected by acoustic emission comes from the object under test itself, rather than from a non-destructive inspection instrument as in ultrasonic or radiographic inspection methods, does not damage the plant and is insensitive to the geometry of the component, and is suitable for inspecting complex-shaped components where other methods are limited. And the system can remind the plants of watering when water shortage occurs, and can intelligently remind the plants of watering in a proper amount, so that the situation that the plants grow badly or die due to too much and too little watering of the users is avoided.
Under the condition that a user can not water in time temporarily, when the lamp 4 is turned on, the timing module starts to time, the set time of the user is reached or the lamp 1 is also turned on, the signal analysis module starts the first motor 7 after obtaining a signal, the water bucket 8 is driven to rotate and water plants, and when the lamp 4 is turned off, watering is stopped. The irreversible water-deficient death of the plants when the users go out for a long time is avoided, but the system is only suitable for the users going out for a certain time, and if the users are not in the long-term, the plants are always in an unattended state and are not suitable for use.
Simultaneously, in the middle of one day, photosensitive sensor can detect illumination intensity to drive third motor 15 makes solar panel face to the direction that light is stronger, and when temperature sensor 3 detected the temperature and is greater than the default, perhaps when lacking water in the plant degree, second motor drive protective curtain dropped and shelters from the sun for the plant, avoids it to be in the sun and insolate down, slows down its moisture and scatters and disappears.
Timing device can be according to setting for regularly sending warning sound, and warning sound can be through broadcast such as trumpet to remind the user to look over and detect vegetation situation, the lack of water condition, and carry out the moisturizing for water bucket 8.
