Gas cylinder filling system and method

Abstract

The invention provides a gas cylinder filling system and method, and relates to the technical field of gas cylinder filling. The gas cylinder filling system comprises an electronic tag, a reader-writer, a controller and filling equipment, wherein when a gas cylinder is placed on a filling scale chassis, the reader-writer arranged on the surface of the filling scale chassis continuously reads the only electronic tag of the gas cylinder to obtain gas cylinder information; the controller judges whether the gas cylinder information is qualified or not, and alarm prompt information is generated according to the gas cylinder information when the gas cylinder information is unqualified, first filling instruction information is generated according to the gas cylinder information when the gas cylinder information is qualified, and the first filling instruction information is sent to filling equipment; and the filling equipment fills the gas cylinder with gas according to the first filling instruction information, and obtains filling record information. The gas cylinder filling system can simplify gas cylinder filling operation, improves filling efficiency and safety, and avoids violation operation in filling.

Description

technical field [0001] The invention relates to the technical field of gas cylinder filling, in particular to a gas cylinder filling system and method. Background technique [0002] When gas cylinders are filled, it is difficult to judge whether the gas cylinders are qualified and whether the filling is sufficient. As a regulatory department, it is impossible to prevent illegal gas cylinders from being filled in the market, and the regulatory pressure is relatively high. Moreover, it is difficult to quickly verify the effectiveness of the gas cylinders during the filling process, for example, due to the overdue period of the gas cylinders and cracks in the gas cylinders. Gas cylinders should be inspected according to the regulations, but the reality is that the filling stations are generally busy, and it is difficult for the filling workers to check the validity of the gas cylinders one by one. Therefore, there have been many vicious incidents of storage tank explosions at ...

Problems solved by technology

As a regulatory department, it is impossible to prevent illegal gas cylinders from being filled in the market, and the regulatory pressure is relatively high

Moreover, it is difficult to quickly verify the effectiveness of the gas cylinders during the filling process, for example, because the gas cylinders are overdue, cracks in the gas cylinders, etc.

Gas cylinders should be inspected according to the regulations, but the reality is that the filling stations are generally busy, and it is difficult for the filling workers to check the validity of the cylinders one by one, so there have been many vicious incidents of storage tank explosions at the filling stations

There are even the following phenomena: For some unqualified gas cylinders, there is "humanity" of the filling workers, and the unqualified gas cylinders are knowingly refilled; in addition, it is cumbersome to manually press the refueling button during the filling process; There is a phenomenon that there is a shortage of catties and two, which harms consumers

[0003] For the above problems, some enterprises have adopted the method of scanning labels with handheld devices to refill gas, but this method still has human factors interfering with the filling of gas cylinders, and it is possible to scan the label of A to fill the gas cylinder of B, which cannot be guaranteed. Safety of Gas Cylinder Filling
