5) Environment Monitoring Unit
The environment monitoring unit (FSU) is a high-performance low-cost FSU (Field Supervision Unit) device integrating Data Acquisition, Intelligent Protocols Processing and Communication Module.
As a smart DAC (Data Acquisition Controller) installed in every telecommunication station or base station in Power Supply & Environment Surveillance System, FSU accesses different sensors to get various environment data and non-intelligent devices status and communicates with intelligent devices (including telecom power supply, lithium battery BMS, air-conditioner, etc.) via RS232/485, Modbus or other kinds of communication interface. FSU captures the following data in real time and delivers to remote monitoring center via B-Interface, SNMP protocol.
