Intelligent gas meter with multistage gas consumption safety detection

Abstract

The invention discloses an intelligent gas meter with multistage gas consumption safety detection, comprising a rectangular case, an LCD segment code screen, a first indicator light, a second indicator light, a third indicator light, a switch, a buzzer, a fastening screw, an ultrasonic module signal input interface, an infrared communication interface, a valve drive interface, a leak detection interface, a program download debugging interface, a power Interface and columns. The beneficial effects of the invention are that the size of the LCD segment code screen is 65mmx26mm, the display content is prompt information consisting of 13 digits, Chinese characters and symbols and the screen is electrically connected with internal components through wires, displaying the information to a user more clearly; and the columns are fixing feet made of cuboid stainless steel blocks welded at the bottom of the rectangular case symmetrically and a layer of rubber pad is cemented at each column by a hot melt adhesive, so that the intelligent gas meter with multistage gas consumption safety detection can be stably and firmly placed.

Description

technical field [0001] The invention relates to an intelligent gas meter, in particular to an intelligent gas meter with multi-level gas safety detection, and belongs to the technical field of intelligent gas meters. Background technique [0002] At present, domestic smart gas meters mainly include IC card smart gas meters, CPU card smart gas meters, radio frequency card smart gas meters, direct-reading remote gas meters (wired remote meters) and wireless remote gas meters (integrated), etc. These categories, and with the improvement of people's living standards and quality of life, the demand for intelligent products required by modern families will promote the development of smart gas meters in the direction of safety, reliability, and smart convenience. Due to the difficulty of charging gas meters, the high labor cost of meter readers, and the fact that theft of gas cannot be truly monitored, this has continuously increased operating costs for gas companies and brought a ...

Problems solved by technology

[0002] At present, domestic smart gas meters mainly include IC card smart gas meters, CPU card smart gas meters, radio frequency card smart gas meters, direct-reading remote gas meters (wired remote meters) and wireless remote gas meters (integrated), etc. These categories, and with the improvement of people's living standards and quality of life, the demand for intelligent products required by modern families will promote the development of smart gas meters in the direction of safety, reliability, and smart convenience. Due to the difficulty of charging gas meters, the high labor cost of meter readers, and the fact that theft of gas cannot be truly monitored, this has continuously increased operating costs for gas companies and brought a lot of trouble to operation and management. Therefore, since 1995, various Smart gas meters are gradually coming into the market in order to solve the headaches encountered in the operation of gas companies, such as IC card meters, CPU card smart gas meters, wired remote gas meters, wireless remote gas meters, network infrared digital gas meters, etc. Varieties appear one after another

[0003] At present, although various smart gas meter products emerge in endlessly, there are some common problems in general. First, the existing smart gas meters do not have a detachable back cover, but use integral welding to ensure The safety of its equipment has caused great troubles in the maintenance of its equipment in the future. Second, the existing smart gas meter does not have a rubber set at the interface, which cannot protect the external wiring. Potential safety hazard, third, the existing smart gas meter is not equipped with a buzzer with a variety of buzzing effects, resulting in the inability to judge what kind of signal it is by buzzing during use
