Description
Technical Field
The invention relates to the technical field of agricultural equipment, in particular to an agricultural spraying device based on RFID and a control method thereof.
Background
It is well known that human life cannot be kept free of supply of animals and plants. The advanced agricultural production is not separated from the use of various pesticides, and the pesticide has become one of effective protection means for animals and plants from diseases, insects and weeds. It is estimated that the loss of animals and plants caused by diseases, insects and weeds in the world can reach about 50% without pesticides, and the loss can be recovered by about 15% by using pesticides. Therefore, the pesticide brings great benefit to people and makes great contribution to human survival.
However, when the pesticide is sprayed on crops, the exceeding of the pesticide on the crops can affect the health of people. Why will pesticides go out of standard? One reason is that farmers cannot control the amount of pesticide to be put in when preparing pesticide spray, and the amount of pesticide to be put in is often excessive. Even if the pesticide is normally sprayed, the pesticide of crops still exceeds the standard. The existing pesticide residue detector detects the pesticide residue degree of vegetables after the fact.
For example, patent publication No. CN102816691A discloses a device for rapidly detecting pesticide residues in fruits and vegetables, which comprises a color development tank, a waste liquid tank, a sample liquid supply device, a color development liquid supply device, a buffer liquid supply device, a substrate supply device, a sample liquid pump, a substrate pump, a color development liquid pump, a buffer liquid pump, a valve system, a reactor and an electronic measurement and control system. The rapid detection device for pesticide residues in fruits and vegetables is used for rapidly detecting the pesticide residues in the fruits and vegetables, and the interference of the color of the fruit and vegetable sample liquid to be detected on the detection result can be completely eliminated. Meanwhile, when the device for rapidly detecting the pesticide residues in the fruits and vegetables is applied to rapidly detecting the pesticide residues in the fruits and vegetables, as enzyme inhibition reaction and enzyme catalysis substrate hydrolysis reaction are all carried out in the same closed reactor, the influence caused by environmental factor change is controlled to the minimum, so that the detection result is relatively more accurate. Although the pesticide residue in the fruits and vegetables can be rapidly detected, the above patent still adopts 'after-the-fact' detection, and the pesticide adding amount cannot be controlled 'in advance'. Therefore, aiming at the problems, the invention provides the agricultural spraying device based on the RFID and the control method thereof, which can control the concentration of the pesticide spray from the source, thoroughly avoid the problem of overproof pesticide after the operation and ensure that people eat safe and healthy crops.

s14, the micro-processing module controls the opening of the electromagnetic valve through the electromagnetic valve driving circuit, and pesticides are added into a tank body of the pesticide spraying device through a liquid inlet; when the pesticide is added into the tank body, a flow meter arranged below the liquid inlet obtains the pesticide feeding amount in real time;
s15, judging whether the added pesticide amount is equal to the searched pesticide proportion amount or not according to the pesticide feeding amount obtained by the flowmeter in real time, and if so, closing the electromagnetic valve;
s16, starting an electric pump switch and starting spraying.
In step S11, the pesticide spraying device is initialized.
Assuming that the electric quantity of the rechargeable storage battery is normal, after a main switch of the device is clicked to start the device, the device is in an initial state, and the initial state is as follows: the electromagnetic valve is closed, the state indicator light is on red, and the electric pump switch is closed.
This example specifically illustrates the currently desired pesticide as pesticide a.
In step S12, the micro-processing module controls the opening of the solenoid valve through the solenoid valve driving circuit, adds water into the tank body of the pesticide spraying device through the liquid inlet, and closes the solenoid valve when the water inflow reaches the required water amount; wherein, set up the flowmeter under the inlet and acquire the inflow in real time when adding water to the jar body.
Firstly, water is added into a tank body, at the moment, a voice module carries out voice prompt on a user, if the user asks to press a water inlet key, the user presses the water inlet key after receiving the voice prompt, at the moment, an indicator light of the water inlet key is turned on, and a status indicator light is turned on and turned green; then voice prompt 'please start to add water', at the moment, the electromagnetic valve is automatically opened;
the user begins to add water, pours water into the device through the inlet, and in this process, the flowmeter calculates/refreshes the inflow in real time, when the user thinks that the required water yield of oneself has been reached, presses the button of intaking again, and the pilot lamp of the button of intaking extinguishes, and the status indicator light is bright red, and voice prompt "the water intaking finishes", and the solenoid valve is closed, and the device records the water yield of adding.
In step S13, the RFID reading head disposed under the liquid inlet identifies the RFID tag of the bottle mouth of the pesticide bottle, and searches for the pesticide proportion amount corresponding to the RFID tag according to the identified RFID tag.
In this embodiment, step S13 further includes:
judging whether the pesticide corresponding to the RFID label is overdue or not according to the identified RFID label, and if so, reminding a user; if not, searching the pesticide proportion corresponding to the RFID label.
The method specifically comprises the following steps: after water inflow is finished, voice prompt is given to 'please identify whether pesticide is overdue', a user takes a pesticide bottle to be used (firstly, the pesticide bottle is not opened), a bottle opening is close to a liquid inlet, an RFID reading head of the device reads and records an ID of an RFID label, the ID is searched in a data set prestored in a storage circuit of the device according to the ID, the expiration time of the pesticide corresponding to the ID is searched, the comparison is carried out with the current time (year, month, day, hour, minute and second) of a perpetual calendar circuit, whether the ID pesticide is overdue is judged, if yes, voice prompt 'pesticide is overdue, please do not use', and the subsequent process is not executed any more; if not, continuing to execute;
the device searches the ratio of pesticide corresponding to the ID (the safety dosage of pesticide A is P as the input amount/ratio amount of each unit of water quantityA) And combining the recorded water quantity (setting the currently added water quantity as P), knowing that the matched medicine feeding quantity is equal to P × PAAnd recording the dosage to be fed.

In step S14, the microprocessor controls the opening of the solenoid valve through the solenoid valve driving circuit, and adds the pesticide into the tank of the pesticide spraying device through the liquid inlet; wherein, when the pesticide is added into the tank body, a flow meter arranged below the liquid inlet obtains the pesticide feeding amount in real time.
In this embodiment, step S14 further includes: when pesticide is added into a tank body of the pesticide spraying device, the RFID reading head periodically reads the RFID tag; judging whether the RFID tags read twice continuously are the same, and if so, continuing to execute; if not, the electromagnetic valve is closed.
Specifically, after the medicine feeding amount of the pesticide A is obtained, a voice prompt of 'please press a medicine feeding button', a user presses the medicine feeding button, an indicator light of the medicine feeding button is turned on, a state indicator light is turned on in green, and a voice prompt of 'please start medicine feeding' is given, wherein at the moment, the electromagnetic valve is automatically opened.
The user opens the bottle cap and begins to pour the pesticide from the liquid inlet. In the whole process from the beginning of pouring the pesticide into the user to the completion of the pesticide feeding (called the pesticide feeding process), the RFID reading head of the device periodically reads the ID of the tag according to a set period, and two comparisons are made:
(1) comparing the ID recorded in step S13 with the ID read at the 1 st time during the bolus administration;
(2) and comparing the ID read out from the Nth time in the medicine feeding process with the ID read out from the (N-1) th time. (N.gtoreq.2, i.e. ratio of 2 nd to 1 st, ratio of 3 rd to 2 nd … …. conventional practice in sampling and control)
If the comparison result of (1) or (2) is inconsistent, the user probably takes another medicine bottle by mistake in the process, the electromagnetic valve is closed immediately, the status indicator lamp is bright red, and the voice prompts 'do not take medicine by mistake'.
If the comparison results of (1) and (2) are consistent, the user operation is normal in the process.
In step S15, it is determined whether the amount of pesticide added is equal to the found pesticide proportion amount according to the amount of pesticide fed obtained by the flow meter in real time, and if so, the solenoid valve is closed.
In the process of feeding, the flow meter calculates/refreshes the amount of the poured pesticide in real time, compares the amount with the amount of the pesticide to be fed in the searched and recorded pesticide proportion amount, and prompts 'feeding is finished' by voice when the amount poured is judged to be equal to the amount of the pesticide to be fed, and the electromagnetic valve is closed; the user presses the medicine feeding button again, the indicating lamp of the medicine feeding button is turned off, the status indicating lamp is in red, and the voice prompts 'please turn on the electric pump switch to start medicine spraying'.
