A method for realizing the identification and control of gas cylinder filling by gas dispenser

Abstract

The invention discloses an implementation method of a gas dispenser recognizing gas cylinders and controlling filling thereof. The implementation method comprises identifying vehicles and gas cylinders, maintaining dangerous identifications of the vehicles and the gas cylinders, automatically recognizing the vehicles and the gas cylinders according to the dangerous identifications by the gas dispenser, carrying out gas filling by the gas dispenser according to recognition results, pushing gas filling records by the gas dispenser, and carrying out electronic settlement of gas filling. Monitoring on operation safety of gas transportation vehicles, online acquisition and monitoring on gas quality, recording on leaving vehicles at a gas station and gas filling safety consumption services are realized. According to the implementation method of the gas dispenser recognizing gas cylinders and controlling filling thereof, vehicles, gas cylinder filling consumption operation and safety production control are combined by means of Internet of Things, industry 4.0, cloud computing, and the big data technology, thereby ensuring that users are safe in consumption and can learn to keep safe in consumption. As a result, accidents of gas vehicles and gas cylinders can be reduced fundamentally.

Description

technical field [0001] The invention relates to a realization method for identifying and controlling an air filling machine to fill a gas bottle. Background technique [0002] At present, gas filling stations (including natural gas filling stations) are dangerous places that are flammable, explosive, and toxic. While clean energy such as natural gas promotes energy conservation and emission reduction, it also brings risks to safety. In order to ensure the safe operation of gas filling stations, it is a key link to prevent the filling of expired gas cylinders, scrapped gas cylinders, unidentified gas cylinders, illegal gas cylinders, and gas cylinders that have been judged to be waste or leaked. Based on the current analysis of domestic gas filling station accidents, most of them are caused by unqualified gas cylinders and irregular operation of gas filling personnel. [0003] With the continuous improvement of the system of laws and regulations on the safety of gas filling ...

AI Technical Summary

Problems solved by technology

[0013] At present, gas filling stations generally use the amount of gas filled to calculate the salary and bonus of gas filling personnel. In order to save time or due to busy reasons, gas filling personnel artificially use handheld explosion-proof terminals to scan the electronic tags of gas cylinders in their pockets. Scan the gas cylinder electronic label actually installed on the vehicle, or do not confirm whether the gas cylinder electronic label is consistent with the gas cylinder qualification label on the gas cylinder when scanning the gas cylinder electronic label on the vehicle, and whether the scanned gas cylinder electronic label is consistent with the actual vehicle information Consistent, the refueling personnel subjectively think that as long as the scan is qualified, I will refuel, resulting in the correlation and consistency of gas cylinders, vehicles, and gas cylinder electronic tags cannot be guaranteed, and accurate identification of gas cylinders has become empty talk

[0014] 2) Limitations of filling control of gas filling machine

[0023] ⑴The keyboard of the refilling machine is a consumable item like a computer keyboard, and the larger the refilling volume, the faster it will be consumed

At the same time, in order to realize the keyboard lock, it is necessary to install a power supply, a relay and a 433MHz wireless communication module inside the gas filling machine. The disadvantage is that the installed power supply affects the electrical performance of the gas filling machine, and the instantaneous opening and closing of the relay will affect the gas filling in a low temperature and dry environment. The accuracy of the mass flowmeter of the gas dispenser caused inaccurate measurement. The 433MHz wireless communication module was installed in the gas dispenser due to the metal shielding, which caused communication instability and affected the accurate locking and unlocking of the gas dispenser keyboard.

[0024] ⑵Due to the rapid development of the current vehicle gas industry, there are nearly a hundred brands of gas dispensers in the country. At present, there is no unified standard for the communication protocol of gas dispensers in the country, so the gas dispenser manufacturers in the country have drawn up and produced their own gas The communication protocol compatible with the gas machine and the gas filling management software have been developed according to customer needs. The communication protocols of the gas filling machine manufacturers are not compatible with each other.

[0033] At present, before filling the gas cylinders and after filling the gas cylinders, the gas filling personnel use hand-held leak detectors to manually detect the valves of the gas cylinders to confirm whether there is leakage. Make sure bottle by bottle inspection is in place
