Skid-mounted full-integrated LNG (Liquefied Natural Gas) and LCNG (Liquefied Compressed Natural Gas) remote control monitored unattended filling station

The utility model discloses a skid-mounted full-integrated LNG (Liquefied Natural Gas) and LCNG (Liquefied Compressed Natural Gas) remote control monitored unattended filling station belonging to a liquefied or compressive gas supply system and particularly belongs to a skid-mounted full-integrated LNG and LCNG field substation. The unattended filling station comprises an LNG storage tank arranged on a skid body, a pump skid, a boosting skid, filling equipment and controlling and monitoring equipment. The unattended filling station is characterized in that the skid body is provided with an anti-explosion variable-frequency governor, an anti-explosion electric appliance cabinet and field substations, wherein the anti-explosion variable-frequency governor is respectively connected with an LNG immersed pump and an LCNG plunger pump; the anti-explosion electric appliance cabinet is respectively connected with all electric equipment; the field substations are provided with PLCs (Programmable Logic Controllers), the input ends of the field substations are connected with all sensors, and the control ends of the field substations are connected with all valves; an electrical distribution room, a control room, a duty room, an office and a rest room are not needed to be built for the filling station on site. Therefore, the station building investment is low, and the building time is short. After a wireless network is used, data are shared by all the substations, and management personnel, maintenance personnel and operators on duty are basically not needed on site.
