Parallel Redundancy System for Critical Conditions Monitoring and Alerting

Monitoring critical conditions is of outmost importance in any system for achieving long life and stability. In this process various parameters can be classified as critical and their values must be kept within a bounded interval by means of monitoring and acting upon parameter change. A practical example of critical conditions monitoring is temperature monitoring in data centers (server rooms) where the temperature value must be kept below a certain threshold in order to achieve long life and stability of the equipment. Within this paper a system designed for monitoring temperatures and alerting of their critical values is proposed - PRSMA. With a parallel redundancy feature that guarantees high reliability of the proposed solution this approach achieves timely alerting upon critical condition, real-time supervision of temperature values and forecasting of the critical conditions. The redundancy aspect is realized using mobile operator link alongside with Internet based landline connection to a Cloud based service – an Internet of Things concept. The proposed architecture is tested in laboratory conditions and the advantages of this approach are shown through measurement and testing
