An under-bridge plant maintenance system and control method thereof

Abstract

The invention discloses a plant maintenance system under a bridge and a control method thereof. The invention realizes automatically injecting tap water into the water storage tank when the rainwater in the water storage tank is insufficient through the setting of a water injection device, a liquid level sensor and a PLC control system, and at the same time utilizes Three connected water storage tanks and three sets of irrigation devices in different positions can fully irrigate the ground green plants and vertical green plants under the viaduct, and use the liquid fertilizer tank and fertilization valve to connect with the irrigation devices to realize the irrigation of the green plants under the bridge. Automatic fertilization and maintenance have the advantages of intelligence, saving, environmental protection, and convenient management.

Description

technical field [0001] The invention relates to an under-bridge plant maintenance system and a control method thereof, belonging to the technical field of gardens. Background technique [0002] In recent years, the greening construction under the urban viaduct has gradually become large-scale. While improving the greening rate of the city, the irrigation of green plants under the viaduct has also become a challenge: (1) Due to the shading of the viaduct deck, the greening plants under the bridge and Vertical greening plants cannot accept the natural irrigation of rainwater; (2) Due to the heavy traffic on the viaduct, it is difficult for large-scale sprinkler trucks to irrigate, and manual irrigation is dangerous and consumes a lot of manpower and material resources; (3) Set up automatic irrigation devices and use urban Irrigation with tap water is a waste of water resources and the cost is relatively high. It is also very difficult to fully water the ground green plants and...
