Description

Technical Field

[0001] The utility model relates to the technical field of intelligent irrigation of three-dimensional flower walls, in particular to an intelligent irrigation controller that can be used for three-dimensional flower walls. Background Art

[0002] As living standards improve, the demand for environmental beautification is growing. As a new form of greening, 3D flower walls, which can be deployed indoors or outdoors as needed, are becoming increasingly popular. Traditional irrigation methods for 3D flower walls involve manual irrigation or manually operated pumps, pipes, and sprinklers. These traditional irrigation methods often result in uneven irrigation and waste of water resources. To address this, intelligent irrigation controllers have been proposed.

[0003] In the prior art, the utility model patent with patent number CN202222742972.0 proposes a garden landscape intelligent irrigation controller, comprising a control box, a box top cover fixedly mounted on the outer surface of the control box, a wind speed sensor fixedly mounted on the upper surface of the box top cover, a box door movably hinged inside the control box, a display screen fixedly embedded in the front of the box door, and a detection controller fixedly mounted on the inner side wall of the control box, the detection controller being electrically connected to the wind speed sensor and the display screen respectively via wires. This garden landscape intelligent irrigation controller, by being provided with a control box, a box door, a wind speed sensor, a display screen, and a detection controller, can play the role of using the wind speed sensor to detect wind speed on windy days, and realize the purpose of the wind speed sensor cooperating with the detection controller and the display screen to display the wind speed value. This is conducive to conveniently adjusting the irrigation liquid speed after viewing the wind speed, so as to avoid the problem of excessive impact on the irrigation liquid when the wind speed is high.

However, the intelligent irrigation controller provided by the aforementioned patent lacks a structure for connecting to various sensors or precision irrigation devices, nor does it process sensor data and control the precision irrigation devices, requiring further improvement.

The three circuit boards are the main control board, the interface board, and the light board. The main control board is the core control board and is placed in the waterproof box and connected to the main bracket through the waterproof box. The waterproof box has threading holes for cables connected to the main control board. The threading holes are sealed with sealant to ensure the waterproofness of the main control board. The main control board is equipped with a single-chip microcomputer, a power management module, a communication module, a switch interface circuit, an indicator light interface circuit, a signal processing circuit, and an output drive circuit. The power management module, communication module, switch interface circuit, indicator light interface circuit, signal processing circuit, and output drive circuit are all electrically connected to the single-chip microcomputer. The single-chip microcomputer can use a 51 series single-chip microcomputer or an STM32 single-chip microcomputer.

[0032] like Figure 1 and Figure 2 As shown, the interface board is provided with a power interface, an input signal interface and an output signal interface. The power interface uses a 3P interface, including an ACL interface, an ACN interface and a PE interface. The power interface is used to connect a 220V external power supply. The input end of the transformer is electrically connected to the power interface, and the external power supply is connected to the transformer through the power interface. A main switch is provided between the input end of the transformer and the power interface. The main switch is used to control the on and off of the circuit between the transformer and the power interface. The output end of the transformer is electrically connected to the power management module. The transformer reduces the 220V power supply to 24V power and provides it to the main control board through the power management module or the power management circuit for use by the electrical components installed on the main control board.
