Measurement And Control

According to the construction situation of intelligent greenhouse in Agriculture Internet of Things in China, designed a measurement and control system of facilities vegetables based on Internet of Things. This design used JN5148 module as the core and applied JenNet stack to set up a wireless network. The environment factors, including temperature and humidity, light intensity, CO2 concentration and so on can be monitored in real-time, at the same time, shutter and water pump were also remote controlled through the GPRS gateway. The test result shows that this system operates stable, measures and controls precisionly, cost low electric quantity and better meet greenhouse environment monitoring and control system applications demand.

For the question of surface density controlled by manual measurement in production process and low quality and inefficiency, we designed the on-line monitoring and control system based on capacitive sensor. The principle is capacitive sensor can convert the surface density variation to the capacitance variation, after operational amplifier, rectifier circuit and filter circuit we can get the voltage signal related to surface density of lithium battery pole piece. The voltage signal through the A/D input module into the PLC for data processing, according to the results we can adjust the coat blade degree real-time. This will achieve the purpose of surface density uniformity. Using this system to replace traditional methods, the lithium battery pole piece surface density can be measured in intelligent, controlled in real-time and non-contact mode with high precision. And this system can improve the quality of lithium battery and the production efficiency, also with great reliability and feasibility.
