Photoelectric-direct-reading wireless remote transmission valve-controlled gas meter

Abstract

The invention discloses a photoelectric-direct-reading wireless remote transmission valve-controlled gas meter which comprises a basic gas meter, a processor and a communication module, wherein the basic gas meter comprises a photoelectric-direct-reading device, a character wheel, an electronic control valve and a signal acquisition module; the photoelectric-direct-reading device, the signal acquisition module, the electronic control valve and the communication module are connected with the processor respectively; the communication module adopts a wireless communication module. The gas meter has the advantages that the photoelectric-direct-reading technology is adopted, so that the meter reading accuracy is high; the valve is built in the gas meter, can be closed in a forced manner, and is stable in control, so that a means is provided for expediting of a gas company; a wireless network is adopted for communication, so that remote concentrated meter reading and monitoring of gas meters can be realized; moreover, the wiring structure is simplified, and a lithium battery is adopted for power supply, so that the power consumption is low; the spread-spectrum communication technology is adopted, so that the gas meter is high in same frequency interference resistance, fading resistance, multipath interference resistance and data security.

Description

technical field [0001] The invention relates to a photoelectric direct-reading wireless remote transmission valve-controlled gas meter. Background technique [0002] For remote meter reading, the core problem to be solved is how to convert the mechanical information measured and displayed by the meter into electronic information that can be processed by the computer, that is, data generation. In a traditional mechanical watch, a magnet is installed on a certain gear, and a magnetically sensitive device, such as a Hall element or a reed switch, is installed at the corresponding position. The magnet rotates with the gear, and when it enters the sensing area of ​​the magnetic sensitive device, the reed switch pulls in and outputs the pulse, and then converts the pulse into flow through the counter circuit. The mechanical meter has the advantages of simple structure and easy realization, but the working principle itself determines that the mechanical meter has a fatal weakness,...

Problems solved by technology

The mechanical meter has the advantages of simple structure and easy realization, but the working principle itself determines that the mechanical meter has a fatal weakness, that is, the problem of missed counting or even non-counting caused by strong magnetic interference, secondary measurement, and low accuracy caused by cumulative errors and the problem of reading errors
