LPG steel cylinder filling system with no-sense supervision function

Abstract

The invention provides an LPG steel cylinder filling system with a no-sense supervision function. The system involves an adding machine, a no-sense radio frequency reader-writer and an electronic tagarranged at the bottom of an LPG steel cylinder, wherein the bottom of the LPG steel cylinder is placed on the no-sense radio frequency reader-writer; the no-sense radio frequency reader-writer is incommunication connection with the adding machine; the adding machine comprises a box body, a filling pipeline arranged in the box body, and an electronic control system arranged in the box body; the filling pipeline comprises an adding pipeline and a gas returning pipeline; the adding pipeline comprises a liquid inlet, a filter, a flow meter, a temperature transmitter, a first solenoid valve, a pressure transmitter, and an adding muzzle; the gas returning pipeline comprises a one-way valve, and a second solenoid valve; and the flow meter, the temperature transmitter, the first solenoid valve,the pressure transmitter and the second solenoid valve are all electrically connected with the electronic control system. The no-sense radio frequency reader-writer acquires information recorded in the electronic tag and then sends the information to the electric control system, the electronic control system verifies and checks the information, the above solenoid valves are controlled to inflate the steel cylinder after the steel cylinder is qualified, and information such as pressure and temperature in the filling pipeline is collected.

Description

technical field [0001] This application relates to the technical field of liquefied gas filling, in particular, to a non-inductive supervision LPG cylinder filling system. Background technique [0002] At present, there are two main ways to supervise the filling of liquefied petroleum gas cylinders: 1. Visually check the inspection mark on the neck of the bottle before filling, and use a scale for measurement during the filling process. The efficiency of this method is not high, and there are often situations such as missing inspections and wrong inspections. When weighing with a scale, there will also be situations such as lifting the bottle for filling, stepping on the scale for filling, etc. 2. On each liquefied gas cylinder, a unique two-dimensional code or RFID label (ceramic, glazed porcelain, enamel, etc. labels can be selected) dedicated to the cylinder is used as its identity. Before filling, the operator scans the QR code label on the liquefied gas cylinder with a...
