Problems solved by technology
Since the base gas filling station should be based on proper natural gas transmission pipelines, the cost of building more gas filling base stations is not only very high, but also it is difficult to guarantee the safety performance of the gas filling base station
[0008] With the increasing demand for CNG in the current society, the current refueling system is far from meeting the needs of the current society; therefore, how to improve the refueling capacity of the refueling sub-station while ensuring the safety of the gas cylinders at the refueling sub-station, Meeting the needs of the current society is a technical problem in this technical field

Embodiment Construction
[0055] The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention. It should be noted that the gas cylinder can be any high-pressure container capable of transporting and storing CNG, such as a large-capacity or small-capacity steel cylinder or even a composite gas cylinder. Gas storage cylinders in the station The gas storage cylinders in the station can be any high-pressure container that can store CNG, such as large-capacity or small-capacity steel cylinders or even composite gas cylinders, or it can be a gas storage or other fixed gas storage installed in a sub-station facility.
[0056] Please refer to figure 1 , figure 1 It is a structural schematic diagram of the first gas filling sub-station pipeline system provided by the present invention. The pipeline system of the gas ...

The invention discloses a gas filling substation as well as a pipeline system, a control system and a control method thereof. A public gas filling substation pipeline system comprises a pressurization mechanism, a gas filling machine and a gas transporting cylinder unit, wherein the gas transporting cylinder unit comprises a gas transporting cylinder and an in-station gas storage cylinder unit; the output end of the gas transporting cylinder is communicated with the low pressure port of the gas filling machine; the in-station gas storage cylinder comprises an in-station gas storage cylinder the nominal working pressure of which is larger than that of the gas transporting cylinder; the in-station gas storage cylinder is communicated with the high pressure port of the gas filing machine; and the output end of the in-station gas storage cylinder is communicated with the gas transporting cylinder via an inlet valve. The pipeline system provided by the invention can enable the CNG discharged from the gas transporting cylinder to be injected into the gas filling machine as well as the in-station gas storage cylinder, so that compressed natural gas at lower pressure in the gas transporting cylinder can be converted into compressed natural gas at higher pressure via the pressurization switch of the in-station gas storage cylinder unit, thus ensuring the safety of the gas transporting cylinder unit and improving the system pressure and the total gas filling capacity of the gas filling substation.
Description
technical field [0001] The present invention relates to a kind of CNG (Compressed Natural Gas, compressed natural gas) gas filling technology, especially to a gas filling substation pipeline system, a control system and a gas filling substation including the above pipeline system and control system, and also to a gas filling substation A method for controlling an air filling substation. Background technique [0002] The use of CNG as fuel has the characteristics of less pollution, safety and reliability, and low operating costs. In order to expand the utilization range of CNG and facilitate the refilling of CNG fuel, gas stations are currently used to refuel cars or other equipment that use CNG as fuel. [0003] The current gas filling system is generally designed in the way of child and mother stations, and the gas filling system includes a gas filling mother station and a gas filling child station. [0004] The refueling master station is connected to the natural gas pip...
