Monitoring management system for liquid nitrogen biological container of cord blood stem cell bank is a system integration product that was studied and developed for five years by our company. By drawing advanced management experience of cord blood stem cell bank at home and abroad, our company uses creatively advanced data collection technology, communication technology, automatic control technology, and embedded software technology.

       The system is mainly made up of remote terminal unit (RTU) of intelligent monitoring of biological container and data service center (DSC). Intelligent monitoring terminal unit has the following functions: real-time collection of temperature of low and high position; real-time monitoring of liquid height; calculation of liquid nitrogen loss; automatic switch of liquid inlet electromagnetic valve according to liquid level and temperature; internal local area network is used to connect tank body computer with server of monitoring center; DTU sends warning message to the cell phone of watch keeper including low-and-high-position overheating warning and sensor failure warning; powerful MIS management system for objects in cryopreservation; and so on

       Data monitoring center analyzes and stores data provided by RTU and these data are investigated by management staff. Monitoring terminal unit can check conveniently the state of every network monitoring terminal by connection of local area network and monitoring center on a computer in the monitoring center without reaching any biological storage container. Monitoring center computer is also in charge of storing and managing all objects stored or to be stored in the liquid nitrogen tank. Monitoring center software is mainly made up of eight major modules including operation model selection, data monitoring, alarming, and object information management.
