Abstract

The invention discloses a natural gas remote charging device and a using method thereof. The device comprises a light emitting device, a wavelength conversion device for receiving a light source and transmitting a light signal, a gas meter reading turntable, an optical fiber collimator, a second transmission optical fiber, a photoelectric signal converter, signal conversion equipment and remote control equipment, wherein the wavelength conversion device is connected with the gas meter reading turntable, an optical signal processed by the wavelength conversion device is transmitted to the second transmission optical fiber through the optical fiber collimator, the second transmission optical fiber is connected with the photoelectric signal converter, the photoelectric signal converter is connected with the signal conversion equipment, and the signal conversion equipment converts an electric signal into a wireless signal and transmits the wireless signal to the remote control equipment. The light emitting device emits the light source to the wavelength conversion device at regular time, so that the use amount of fuel gas can be monitored at regular time; a single-chip microcomputer processes and encodes the electric signals converted by the photoelectric detector; and the output digital information is converted into wireless signals through the signal conversion equipment. Naturalgas remote charging is achieved, and time and labor are saved.

Description

technical field [0001] The invention relates to the field of data collection, in particular to a natural gas remote billing device and a using method thereof. Background technique [0002] Natural gas pipeline refers to the pipeline that transports natural gas from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas transmission pipelines. The use of natural gas pipelines to transport natural gas is a way to transport large quantities of natural gas on land. Natural gas pipelines account for about half of the world's total pipeline length. [0003] Because it is very dangerous to introduce wires around the natural gas pipeline, the current natural gas billing cannot realize remote billing like electricity and water bills, and still requires a method of manually collecting the data on the gas meter of natural gas. Such a method is time-consuming and laborious, and cannot regularly monitor the consumption of g...
