Skid-mounting full integration LNG and LCNG remote monitor unattended filling station

The invention discloses a skid-mounting full integration LNG and LCNG remote monitor unattended filling station, belongs to a liquefied or compressed gas supply system, and particularly relates to a skid-mounting full integration LNG and LCNG on-site substation. The skid-mounting full integration LNG and LCNG remote monitor unattended filling station comprises an LNG storage tank, a pump skid, a boost skid, a filling device and a control and monitor device which are installed on a skid body. The skid body is provided with an explosion-proof variable-frequency speed regulator connected to an LNG immersed pump and an LCNG plunger pump, an explosion-proof electric appliance cabinet connected to electric equipment, and the on-site substation using an PLC controller and with input terminal connected to sensors and control terminal connected to valves. The filling station is in no need of constructing a switching room, a control room, a duty room, an office and a rest room on site. Therefore, investment for constructing the station is reduced and construction time is shortened. When wireless network is used, the data of substations can be shared; and the site is in no need of management personnel, maintenance personnel and duty personnel basically.
