Passive maintenance-free fluid flow measuring instrument based on intelligent network

Abstract

The invention provides a passive maintenance-free fluid flow measuring instrument based on an intelligent network. The instrument comprises an instrument shell, an electric quantity generating fan blade is arranged in the instrument shell, and a flow baffle is arranged on one side of the electric quantity generating fan blade in a sealing manner and is communicated with an inlet; a control shell, an electric quantity storage farad capacitor, a MESH control system circuit board and a display are arranged above the instrument shell, the electric quantity storage farad capacitor is electrically connected with the electric quantity generating fan blade through a current magnitude monitor, the MESH control system circuit board is electrically connected with the electric quantity storage farad capacitor, the current magnitude monitor and the display, the MESH control system circuit board is further wirelessly connected with intelligent terminal equipment; an electronic instrument is adopted, electric quantity is generated through fluid driving to supply power, disassembly and replacement of a battery are avoided, metering is more accurate, wireless connection with the intelligent terminal equipment can be achieved through MESH networking, remote data monitoring is achieved, the intelligent function and convenience of instrument equipment are greatly enhanced, and the remote meter reading effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of smart instruments, in particular to a passive and maintenance-free fluid flow measuring instrument based on an intelligent network. Background technique [0002] At present, most energy metering instruments such as water meters and gas meters in residential buildings in our country are installed indoors, and the monthly water and gas meter reading fees bring a lot of inconvenience to users and meter reading personnel. The Ministry of Construction has clearly stated in the "Guidelines for Planning and Design of Moderately Prosperous Urban and Rural Housing Science and Technology Industry Engineering City Demonstration Areas in 2000" that "promote the application of outdoor metering (including water, electricity, heating, and gas meters) technology"; in "China Housing Industry Development The "Outline" also clearly stated that it is necessary to "realize convenient meter inspection without disturbing reside...
