The invention provides a natural gas supply control system which achieves intelligent control to a natural gas supply system. The natural gas supply control system comprises electronic valves arranged at a joint of each pipe; a pressure sensor arranged at an outlet of a liquefied natural gas (LNG) storage device and used for outputting a pressure signal; a controller outputting a control signal to a control terminal of each electronic valve and receiving a working condition signal of each electronic valve and the pressure signal outputted by the pressure sensor; a control panel used for human-machine interaction which is connected with an output end of the controller in a coupled mode and displays the working condition of each module of the natural gas supply system and a general packet radio service (GPRS) module which is connected with the output end of the controller in a coupled mode and sends the working condition of each module of the natural gas supply system to an upper computer.
Description
technical field [0001] The invention relates to the field of automatic control, in particular to a natural gas supply control system. Background technique [0002] Natural gas has become the main household fuel in my country. For urban residential areas, the natural gas supply network has reached thousands of households. For rural areas and old urban areas where there is no gas supply network, old-style gas tanks are still used to provide fuel. Not only the cost High and dangerous. [0003] Patent No. ZL201020510691.7 discloses a liquefied natural gas supply system for a community, including LNG liquefied natural gas (liquefied natural gas) storage containers, valve piping systems, liquid level measurement systems, distributors, vaporizers, safety accessory pipelines and pressure regulators Pressure stabilizing system, in which the LNG storage container is connected to the liquid inlet pipeline of the valve pipeline system through the liquid inlet stop valve and the liquid i...
