The database can store 16G measurement data. It is the specific technical index to complete the industrialization cultivation project of Shaanxi Education Department. This paper starts with the structure design of agricultural water quality remote intelligent monitoring system, combining with the technology of Internet of things (IOT) and PLC technology, sensor fusion technology. A set of remote intelligent monitoring system for agricultural water quality is designed. The main work of this paper is as follows: 1. Firstly, the development and present situation of water quality monitor at home and abroad are analyzed. The overall structure of the water quality remote monitoring system is studied in combination with the actual technical indexes and requirements of the industrialization cultivation project of Shaanxi Provincial Education Department. Developed a set of agricultural water quality remote intelligent monitoring system. 2. Completed the hardware design and manufacture of agricultural water quality remote intelligent monitoring system. After allocating the resource of I / O port of PLC, the concrete connection scheme of the remote intelligent monitoring system of agricultural water quality is given. According to the principle and output characteristics of the water quality sensor, the conditioning circuit PCB of the water quality sensor is drawn. Make a separate module. 3. Completed the agricultural water quality remote intelligent monitoring system PLC ladder diagram and embedded touch screen configuration software design and programming. According to the actual demand of agricultural water quality monitoring, the intelligent mode function of the water quality monitoring system is completed, and the Modbus protocol of the remote intelligent monitoring system of agricultural water quality is completed. The system can send data to the COMWAY Internet of things cloud service platform through DTU, and complete the configuration design of the monitoring system on the computer side. Achieve real-time data acquisition, historical data query, alarm, agricultural water use control function. 4. According to the characteristics of water quality sensor, the sensor signal correction and compensation method is studied. According to the specific water quality data, a curved surface fitting temperature compensation method is given to reduce the temperature to salinity, turbidity, pH, conductivity, ammonia nitrogen content. The above work has completed the research and development of the industrialization cultivation project of Shaanxi Education Department. In order to ensure the safety of 1100 mu orchard irrigation water in Yangyuzhen, Xianyang City, Shaanxi Province, the system is applied in the park. The safety of irrigation water in the park is guaranteed, and the design purpose of the system is achieved.
