Description

Intelligent plant seedling raising machine Technical Field The invention relates to the technical field of intelligent agricultural equipment, in particular to an intelligent plant seedling raising machine which can automatically track a light source, monitor environmental parameters and realize man-machine interaction. Background With the rapid development of facility agriculture and home gardening, plant seedling raising equipment gradually changes from traditional static planting to intelligent management. However, the prior art still has the following significant drawbacks: (1) The passivity and inefficiency of illumination regulation are that most seedling raising equipment (such as the forestry seedling raising device described by CN 216219039U) adopts a fixed light supplementing lamp or relies on natural light, and cannot be dynamically regulated according to the sun position, so that uneven illumination intensity distribution is caused. Especially in overcast and rainy weather or indoor environment, the light receiving surface of the plant is single, and the photosynthetic efficiency is obviously reduced. Although some devices (such as the intelligent water planting device described in CN 209768507U) improve illumination through LED light supplement, they are required to be turned on all the time, the energy consumption cost is high, and the spectrum range is different from natural light, so that the plant is easy to grow or develop deformity after long-term use. (2) The motion control and the adaptability are insufficient, the existing equipment (such as the hydroponic monitoring device described by CN 213637922U) mostly adopts a horizontal rotation or fixed lifting structure, and the cooperative motion in the three-dimensional space can not be realized. For example, conventional rotating cultivation racks can only rotate around a single axis, and it is difficult to ensure that the plant leaves are always perpendicular to the incident light, resulting in a backlight surface in a low light state for a long period of time. Part of lifting devices (such as a hydraulic driving system) have the risk of liquid leakage, or a gear transmission mechanism (such as a garden maintenance robot described by CN 206525205U) is blocked due to insufficient load capacity, so that long-term reliability is affected. (3) The environment monitoring and interaction functions are lacking, the prior art relies on periodic manual detection (such as manual measurement of soil humidity) or only collects data through a simple sensor (such as a single temperature and humidity probe), and the real-time fusion analysis of parameters such as illumination intensity, pH value, inclination angle and the like is lacking. Meanwhile, the traditional equipment lacks a visual interface and voice interaction function, so that a user cannot remotely acquire plant states or receive early warning information (such as water shortage alarm), and the usability and user experience of the equipment are reduced. (4) The energy dependence and sustainability are limited in that most devices need to be continuously connected with the mains supply, and the devices are difficult to apply in areas without power grid coverage (such as remote farmlands or outdoor balconies). Although some researches try solar power supply, the photovoltaic panel is fixedly installed, and cannot adjust the angle along with the movement of equipment, so that the photoelectric conversion efficiency is low. Based on the problems, the academic world and the industry put forward partial improvement schemes, but the limitation still exists that 1. Preliminary exploration of a light following system is that CN213637922U monitors the growth state of crops through a camera, but only passive image acquisition is realized, the linkage with mechanical motion control is not realized, and CN209768507U adopts a timing rotation strategy and lacks dynamic feedback adjustment based on illumination intensity. 2. Attempts at modular design have been made in part of the patents (e.g., CN 216219039U) to simplify the operation of growing seedlings by removable structures, but do not address the integration of environmental parameter monitoring with automated irrigation. 3. The partial scheme of energy consumption optimization is that the existing solar energy equipment mostly adopts a fixed photovoltaic panel (such as CN206525205U0, which is not coupled with the equipment movement mechanism, so that the energy utilization rate is less than 30 percent. Based on the analysis, there is a need for an intelligent plant seedling raising device with multiple degrees of freedom motion control, real-time fusion feedback of environmental parameters, low energy consumption and support of man-machine interaction. Disclosure of Invention The invention aims to provide an intelligent plant seedling raising machine which overcomes the defects in the prior art. In order to achieve the above purpose, the present in
