Method for controlling safe filling of vehicle gas cylinder

Abstract

The invention discloses a method for realizing safe filling control of a vehicle gas cylinder by radio frequency identification and computer technology, which comprises an electronic tag, a tag recognition device, a filling controller and relevant software; wherein, the electronic tag is stuck on the cylinder body; the tag recognition device communicates the read tag information with the filling controller arranged in a gas dispenser control chamber via a wireless network; the filling controller is communicated with a gas dispenser monitoring background via a COM port connecting wire in accordance with that the tag information is converted into corresponding instructions; the gas dispenser background controls whether a gas gun is unlocked according to the instructions so as to dispense the vehicles to realize automatic filling of the gas cylinder and completely avoid the interference of human factors on dispensing; after filling is finished, the filling controller extracts dispensing records from the gas dispenser monitoring background and stores the records. Without changing the electrical structure of the gas dispenser, the method realizes automatic identity recognition and acquisition of filling information during filling, connects the filling controller with data centers of supervision departments via communication networks and realizes the functions of downloading gas cylinder blacklist and uploading gas cylinder dispensing information in real time.

Description

technical field [0001] The invention relates to a control method for safe filling of gas cylinders for vehicles, in particular to a control method for realizing safe filling of gas cylinders for vehicles by using electronic label technology and computer technology. Background technique [0002] With the rapid development of the economy, the continuous rise of global oil prices, the adjustment of energy structure, and the country's emphasis on environmental protection, the number of gas vehicles and automobiles converted from oil to gas is increasing. At present, there are hundreds of thousands of natural gas vehicles in my country. With the improvement of the domestic gas supply system and the construction of the nationwide gas station network, the number of natural gas vehicles will continue to increase. The successful promotion and application of natural gas has solved the problems of automobile alternative energy and environmental pollution to a large extent, but its safe...
