NEW AGE UPS WITH BATTERY MONITORING USING RASPBERRY PI

Atremoteplaces wherecontinuouspowerrequirementisnecessarybatterybanks andinvertersareused to cater the power to different systems and instruments, in case of AC mains failures. In this paper a real time web based system is proposed to monitor and select one of the available power source automatically for providing uninterrupted power to the load through battery and provides information of health condition of battery at remote site. The whole system is built on Raspberry Pi using the Raspbian operating system and framework library for remote access. The programming of the system is done by using Python for GPIO programming of Raspberry Pi development board. The availability of three input sources are detected by ADC and information is forwarded to Raspberry Pi using SPI protocol. The information about available and connected and disconnectedpower sources are detected by using logger function which log the data in a file. Threading library used for continues sensing of the all sources.

This dissertation attempts to study the remote monitoring and control is one of the most important requirements for maximize the process plantavailability
