Design of fire information transmission unit based on energy storage power station

According to the data acquisition requirements of automatic fire detection system and monitoring system of energy storage power station, an embedded data acquisition device based on arm in embedded Linux environment is designed and developed. The device itself supports 100 MLC optical fiber interface, 10 m /100 m adaptive RJ45 electric port and 8-way RS485 communication interface. At the same time, it can realize 8-way
$4\sim 20 \ \text{mA}$
signal acquisition and calculation and 2-way can communication interface through arm processor, and effectively suppress power frequency interference. Support the traditional communication protocols of power system, such as modbus, CDT, 103, 101 / 104, and the communication protocols of intelligent substation, such as IEC61850, MMS and goose. The unit module realizes the real-time upload and distribution of fire information.
