| Photosynthesis maintains the growth of plants and the stability of carbon and oxygen in the ecological environment.The reaction of photosynthetic rate has become the key link of plant photosynthetic monitoring.The photosynthetic apparatus developed in this subject lacks the same type of mobile monitoring method in the existing equipment,the photosynthetic instrument developed in this subject has some disadvantages in the monitoring process,such as cumbersome operation steps,deviation of data sharing,large volume and inconvenient to carry,which affects the user experience and application ability of this series of instruments.Aiming at the defects in the operation of plant photosynthesis monitoring,this study designed a portable and self detachable monitor with Android mobile terminal monitoring method as the core.Through 3D modeling integration,strawberry and Geranium plants were taken as test objects to perceive the photosynthetic physiological information of the two plants.Finally,the information was transmitted to the mobile terminal by wireless communication technology.The accuracy of the instrument was verified by comparison.The main research work is as follows:(1)Design of plant photosynthesis monitoring hardware system based on mobile sensing.By monitoring the content of oxygen released by plants and other photosynthetic research methods,the microprocessor Arduino control board is used as the main control module of the embedded system,the DS3231 real-time clock,SD card storage and Bluetooth communication module are designed for data management and transmission,and the pumped oxygen sensor,AWM3100 V flowmeter and other sensors are connected to sense the physiological indicators of plants,so as to calculate the photosynthetic intensity of photosynthetic rate response of plants.(2)Development of plant photosynthesis monitoring software system for Android mobile terminal.The embedded data information for sensing plant photosynthetic physiology is designed,and the wireless Bluetooth and data receiving and sending technology are used to make the client have strong manipulation ability and hand-held monitoring effect;Using UI interaction,database storage and chart drawing technology,the data visualization function and data management ability of Android client are enriched;The Web Socket protocol enables the local data stored in the Android client to be uploaded to the Web for data management,analysis and comparison,so as to improve the real-time sharing effect of monitoring plant photosynthetic data to a certain extent.(3)Development of portable instrument for plant photosynthesis monitoring based on3 D modeling mechanical structure standard.According to the standard photosynthetic apparatus and portable principle,the overall design process is studied,and the structural design of each part is summarized.Based on the above,modular modeling and parametric design are proposed,and the portable detachable monitor is divided into three main parts:chassis,leaf chamber and fixed components.The structural features are analyzed and the parametric drawing is carried out in combination with CATIA.Finally,a portable instrument with multi blade measurement and detachable body is designed with 3D printing technology.This research develops a plant photosynthetic instrument based on mobile terminal monitoring.After testing,comparative analysis and experiments,it shows that this monitor makes up for the shortcomings of the original equipment operation,and provides a new idea for the monitoring method of plant photosynthesis.The monitor developed by the mobile sensing method is convenient to use and improves the application ability of the plant photosynthetic monitor.Therefore,this study has great reference value for the development of the same type of agricultural equipment informatization. |
