[0002] Modern landscaping is dedicated to improving the ecological environment. The goal is to create urban parks, including scenic roadside areas and natural ecological parks dominated by green forests and lawns—all aimed at making cities more beautiful and fostering harmony between people and nature.
[0003] Irrigation systems are a crucial component in achieving urban landscaping. Currently, my country's landscaping relies primarily on unified irrigation, which is relatively simplistic and uses relatively crude irrigation techniques. Water resource recycling rates are also lower compared to other refined irrigation methods. With the rapid development of the national landscape architecture industry and increased awareness of water resource protection and recycling, the shortcomings of traditional irrigation methods are becoming increasingly apparent. There is an urgent need to optimize and improve the currently prevalent, simplistic irrigation methods to enhance irrigation efficiency and water resource utilization.
[0004] Currently, most garden and greening irrigation systems use programmable logic controllers (PLCs) for control. This involves setting up a control host in a monitoring room with several substations. While this can achieve automatic irrigation, the hardware is relatively complex and the setup cost is high. In addition, the remote monitoring function is relatively simple and the operation flexibility is poor, requiring a certain amount of human resources. Utility Model Content
[0005] To address the aforementioned technical problems, this invention proposes an Internet of Things (IoT) control system for landscaping irrigation. This system uses a digital acquisition unit and an analog acquisition unit to collect real-time information on the pump's operating status, irrigation water volume, and humidity of the target irrigation area during the irrigation process. The monitoring information is then transmitted to mobile terminals and PCs via a programmable control module and a 4G module, enabling remote monitoring and facilitating timely detection and resolution of problems in the irrigation system by staff.

[0011] It also includes a 4G module, through which the programmable control module connects with mobile terminals and PCs.
[0012] Furthermore, the switch quantity acquisition unit includes a flow switch, a float switch, and a switch quantity acquisition module. The flow switch and the float switch are electrically connected to the switch quantity acquisition module, and the switch quantity acquisition module is electrically connected to the programmable control unit.
