Design on Multi-parameter Measurement and Control System for Tissue Culture Laboratory

Tissue culture lab is a place of culturing vaccination materials in the process of breeding. Measurement and control of temperature, humidity and illumination is the essential condition. At present, exist many problems in measurement and control system, such as the low controlling precision, mutual interference between temperature and humidity controlling, energy waste. In addition, the data of experimentation could not be measured, recorded, stored and handled. The price of foreign product is so expensive that general units can´t accept it. In order to solve these problems, measurement and control of temperature and humidity was studied to develop more applicable multi parameter measure and control system with low price and stable performance, so that the temperature, humidity and illumination indicator can be automatically measured and controlled. In this article, according to status quo of tissue culture lab and requirement of temperature and humidity control and system function, the system overall structure was built, The system working process, characteristic and main technical indicator were introduced.
