Description

Technical Field

[0001] This invention relates to the field of detection equipment technology, specifically a device for real-time detection of the water and fertilizer status of plants. Background Technology

[0002] To better collect crop behavior data and utilize the principle of negative feedback to guide irrigation, we aim to reduce energy and fertilizer costs while promoting better crop growth, thus making agricultural planting more intelligent and standardized. Currently, substrate scales that only collect mass data (used to measure the weight of coconut coir strips and monitor plant growth) are insufficient for our daily planting needs. They cannot automatically collect water and fertilizer information, nor can they record data changes from every device throughout the entire process. This hinders the provision of accurate and effective data to support users in developing subsequent water and fertilizer supplementation strategies, and prevents users from adjusting the pace of fertilizer and water control, thus preventing optimal resource allocation. To address these issues, we propose a device for real-time monitoring of plant water and fertilizer status to provide effective data support for smart agriculture and to collect environmental parameters throughout the entire crop growth process. Summary of the Invention

[0003] The purpose of this invention is to provide a device for real-time detection of plant water and fertilizer status, which aims to provide an effective data support for smart agriculture by collecting environmental parameters throughout the entire crop growth process.

[0041] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0042] Please refer to Figure 1 and Figure 2 According to a first embodiment of the present invention, a device for real-time detection of plant water and fertilizer status includes: a mounting frame 1 with an opening at its upper end; a first weighing sensor 14 mounted on the mounting frame 1 for weighing the substrate; a soil temperature and humidity sensor 25 for detecting the temperature and humidity of the substrate; a liquid inlet tank 16 mounted inside the opening at the upper end of the mounting frame 1; a first EC sensor 18 disposed inside the liquid inlet tank 16 to detect the EC value of the liquid inside the liquid inlet tank 16; a first pH sensor 19 disposed inside the liquid inlet tank 16 to detect the pH value of the liquid inside the liquid inlet tank 16; and a liquid supply mechanism for delivering the liquid in the liquid inlet tank 16 to the substrate.

[0043] In this specific embodiment, the substrate is placed on the first weighing sensor 14, which allows for real-time weighing of the substrate and provides a direct visual representation of weight changes. A soil temperature and humidity sensor 25 is inserted into the substrate to monitor data changes in real time. The nutrient solution tank 16 stores nutrient solution or irrigation solution required for plant growth. The nutrient solution supply mechanism includes a water pump 17, which extends into the nutrient solution tank 16 via a suction pipe (not shown) and delivers the solution to the substrate via a discharge pipe (not shown). Because a first pH sensor 19 and a first EC sensor 18 are provided, the liquid EC value and pH can be monitored during nutrient solution delivery. The device can detect the values, so it can collect the environmental parameters and water and fertilizer status of the plant in real time during the plant growth process. It should be noted that the liquid inlet tank 16 is preferably fixed on the bottom wall of the mounting frame 1, for example by snap-fit ​​or bolt, or it can be placed directly on the bottom wall of the mounting frame 1. The detection end of the first EC sensor 18 and the detection end of the first PH sensor 19 both extend into the interior of the liquid inlet tank 16.

[0044] In another specific embodiment of the present invention, an industrial control motherboard 22 is installed inside the mounting frame 1. The first weighing sensor 14, the soil temperature and humidity sensor 25, the first EC sensor 18, and the first pH sensor 19 are electrically connected to the industrial control motherboard 22.
