Abstract

The invention discloses a novel pulse metering device in a fuel gas meter end and a metering method, and relates to the technical field of fuel gas metering devices. The novel pulse metering device in the fuel gas meter end mainly comprises a photoelectric sensor, an MCU, a counting gear and a transmission gear. The photoelectric sensor comprises a photoelectric transmitting tube and a photoelectric receiving tube, the photoelectric sensor is used as a metering switch, and the MCU is used for conducting on-off control and signal processing. According to the scheme, reflecting mediums are added to the counting gear and are used as on-off mediums of the photoelectric sensor, when the photoelectric sensor identifies a white medium, the photoelectric sensor outputs a voltage to the MCU, when the photoelectric sensor identifies a black medium, the photoelectric sensor outputs another voltage to the MCU, and then the MCU achieves a metering function by distinguishing signals of different voltages. According to the novel pulse metering device in the fuel gas meter end and the metering method, the novel metering device has the advantages of being accurate in metering, strong in anti-light capability, low in power dissipation and cost, simple in process, high in production efficiency, and strong in anti-interference capability.

Description

technical field [0001] The invention relates to the technical field of gas metering devices, in particular to a novel pulse metering device and a metering method at a gas meter end. Background technique [0002] In recent years, the smart gas meter industry has developed rapidly, and the situation is still developing in a good direction. The industry has higher and higher requirements for meter meter safety and accuracy, especially how to achieve anti-interference, reduce power consumption, and reduce failures. This is especially true for the requirements of the five aspects of high efficiency, improved reliability, and reduced manufacturing costs. [0003] Today, the pulse measurement methods of smart gas meters include the following three methods: [0004] 1. Reed switch magnetic control measurement method: the combination of reed switch sensor, magnet and counting gear is used to realize the measurement function; [0005] 2. Hall magnetic control measurement method: the...
