Crop Planting Environment Monitoring And Quality Traceability System

There are still many problems in the use of agricultural informatization and automation technology in China.Due to the limitations of expertise and technology,most growers still rely on human resources to manage the cultivation of crops with experience.Some areas are limited by terrain,unable to lay fiber and cable,and set up a wireless network environment.Even if the network environment and power transmission equipment can be built,the high cost of laying can make many managers discouraged,and can not really enjoy the increase in production and income brought by informationization.Today's food safety issues have been highly valued by the state,and the traceability system that records the entire planting information of crops is an effective means of regulating food safety.It is necessary to develop a hardware device that automatically monitors the crop planting process based on solar power supply,and an interactive traceability system that can provide consumers with information on planting management information.In response to the above problems,the crop planting environment and quality traceability system were designed and developed.On the hardware device,stm32f103 is used as the data processing chip,HSTL-102 STRWS soil temperature and humidity sensor and SHT20 air temperature and humidity sensor are used as the environmental monitoring module.The sensor transmits data through the UART and I2 C and the microcontroller.The device is powered by a hybrid of solar panels and lithium batteries,and the utility power supply mode.It solves the problem that the transmission line cannot be laid because of special terrain,which saves energy to some extent.Aiming at the shortcomings of traditional collection devices,such as transmission distance limitation,high wiring cost and poor mobility,the GPRS remote data transmission method is used to solve related problems,and the whole process automatic monitoring of planting environment information is realized.In terms of software platform,the B/S architecture design platform was chosen to solve the problem of high hardware requirements of the traditional C/S architecture.The administrator can monitor the environment and enter the traceability management information on any browser carrier,thus avoiding the disclosure of information.In order to eliminate the rule restrictions of third-party IoT organizations,Alibaba Cloud was chosen as the server vendor to build a configuration server development environment.Design interface program with hardware to realize real-time monitoring of environmental parameters around the clock.According to the requirements of the use of the scene design MySQLdatabase,determine the data table format,to ensure the comprehensiveness of the data entered.In order to better suit the usage habits of grassroots people,use HTML+CSS+JavaScript+PHP to develop web applications,reduce front-end input as much as possible,and more by the back-end logic.The software platform can record and query the whole process information of crop seed source,seedling source,aply fertilizer,pesticide,harvesting and transportation.The system realizes real-time monitoring of crop planting environment information around the clock,and the monitoring device can be fully automated.It realizes the traceability information of the whole process of crop planting in the database,and the real-time uploaded data of the monitored area is fed back to the users and consumers in the form of webpages,thereby realizing the planting environment monitoring and traceability function of agricultural products.It has the advantages of strong adaptability,high degree of informationization and low cost,which is conducive to improving agricultural production efficiency and reducing food safety problems in China.
