Design and Development of the LNG Dispenser
Abstract: Be seriously challenged, as the world’s energy problems have become increasingly prominent, the traditional energy structure in China, at the same time, global warming, air pollution and other environmental issues also threaten our homes, building a sustainable social atmosphere to become the current trend of the times. Liquefied natural gas (LNG) as a new kind of efficient, clean energy, gradually been widely used in China’s urban bus and taxi. According to LNG stations need accurate billing, monitoring and management when the vehicles add LNG, designed a kind of LNG dispenser which used in the LNG station, and developed the overall structure of the LNG dispenser hardware and soft-ware, completed the power circuit, control circuit, the loop circuit, display circuit, achieved the 485 communication between the MCU and mass flow meter in the MODBUS protocol, and a brief introduction of the workflow of the entire system in the filling process. After the commissioning, the machine completed all operations, with pre-cooling process is quick, smooth filling, accurate measurement, and showed wide application prospects.
