Remotely controlled intelligent gardening irrigation system and control method thereof

Abstract

The invention discloses a remotely controlled intelligent gardening irrigation system and a control method thereof. The remotely controlled intelligent gardening irrigation system includes an irrigation pipeline system and a wireless control system. The irrigation pipeline system includes a main line and at least one branch line. A main solenoid valve is arranged in the main line. A water pump isconnected to a water inlet pipe through the main solenoid valve. A flow sensor and a sub-solenoid valve are arranged in each branch line. The inlets of the sub-solenoid valves are connected to the main line. Each outlet of each sub-solenoid valve is connected to a branch line water outlet pipe through each flow sensor. The wireless control system includes a computer. The computer is connected to aGSM controller through a first usb data collection device to obtain an irrigation instruction sent by a mobile phone. The computer is connected to an external environment monitoring module and the flow sensor through a second usb data collection device. A labVIEW control system is arranged in the computer. The labVIEW control system controls the main solenoid valve, the water pump and the sub-solenoid valves to work through the first usb data collection device. The remotely controlled intelligent gardening irrigation system adopts the lacVIEW control system for the system control to realize intelligentized and highly reliable intelligent remote irrigation.

Problems solved by technology

[0003] Existing products, authorized patents, published literature, etc. mainly build a novel function realization method around this general idea or principle. Although it can realize remote watering functions such as plants and crops, remote watering is more concerned about users. Feasibility analysis and research have not been carried out on the core aspects of irrigation system intelligence, reliability, and control quality, especially when it comes to precious crops and botanical garden breeding bases that require intelligence (less labor demand), control accuracy, and reliability. Once the remote watering system fails to water or the watering cannot be stopped, it will cause the crops and plants to dry out or die from waterlogging, and the loss will be irreparable. The specific shortcomings are as follows:

[0004] 1. Insufficient control precision

Most irrigation systems use time relays to set the time to determine the irrigation amount, and calculate the irrigation amount by time, without considering the influence of fluid flow instability on the calculation results, resulting in a large difference between the theoretical demand and the actual irrigation amount

[0005] 2. Not intelligent enough

(1) Most irrigation systems use mobile phones to remotely control the connection and disconnection of the GSM output corresponding pins, that is, the mobile phone APP needs to have two virtual buttons for starting and stopping the same irrigation task, and it needs to be manually clicked on and off. The system cannot automatically recognize the end of watering and close the actuators such as water pumps and valves

(2) Intelligent remote watering needs to comprehensively analyze the expected watering amount of the irrigated crops and plants and the actual environment (rain season, air humidity, ambient temperature) and give the actual amount of irrigation required regularly. However, the current remote watering system does not Does not have this intelligent function

[0006] 3. Low reliability

The valves and water pumps of most remote irrigation systems are directly controlled on and off by the GSM remote controller. Highly demanding electrical components, industrial or civilian AC relays need to be tested by an authoritative testing agency. The relay function of the existing GSM controller has not been tested by an authoritative agency. Directly using the GSM controller to control the switch of power equipment has reliability risks.

[0007] 4. Not professional

However, it is impossible to achieve intelligent judgment and mobile phone remote alarm function for whether the watering is completed, whether there is a fault in the system, and what kind of fault.

[0009] Although the above method can protect the system from abnormalities, it cannot make a correct judgment on whether the remote irrigation that is most concerned about in irrigation has been realized, and whether the actual irrigation has reached expectations. It is not intelligent enough and lacks fault diagnosis functions. The disadvantages

[0010] Although there are a few irrigation system products in the market that have a fault diagnosis function, for example, fault alarms can receive information through mobile phones, but the specific situation of the diagnosis function is not described in detail, that is, there is no description of diagnosis strategy, diagnosis logic, and fault point judgment basis.
