Problems solved by technology
At present, the data collection of flowmeters is usually realized through the built-in boards of industrial control computers. Since flowmeters are often distributed in various areas, especially in remote places, the monitoring of equipment and statistics of data are very inconvenient and difficult, and The display of the current flowmeter mainly relies on the built-in battery or external power supply as the power supply mode, and there is a problem that it is inconvenient to replace the battery regularly or set up an external power supply.

The invention relates to a self-powered sensor network flowmeter, particularly to a liquid turbine flowmeter applied to long-distance or poor-condition transportation of petroleum, natural gas, liquefied gas, supply or drainage water and the like. The self-powered sensor network flowmeter comprises an impeller and a control room; a storage battery is connected with a display and a radio frequency module and powers the display and the radio frequency module, and the radio frequency module transmits wireless signals through a transmitting antenna; the control room receives the wireless signals transmitted by the radio frequency module through a receiving module to collect and monitor the data of the whole sensor network flowmeter. According to the self-powered sensor network flowmeter, by means of the radio frequency module composed of a WIFI (wireless fidelity) module and a 3G (third generation) communication module, and the storage battery for powering the flowmeter, the managements and services such as long-distance real-time online detection and alarm action and the function of self powering can be achieved.
Description
technical field [0001] The invention relates to a self-powered sensor network flowmeter, in particular to a liquid turbine flowmeter used in long-distance transportation of oil, natural gas, liquefied gas, water supply and drainage, or poor working conditions. Background technique [0002] Turbine flow meters are a well-established technology that has found wide application in measuring the flow of liquids that fill closed pipes and flow continuously. At present, the data collection of flowmeters is usually realized through the built-in boards of industrial control computers. Since flowmeters are often distributed in various areas, especially in remote places, the monitoring of equipment and statistics of data are very inconvenient and difficult, and The current display of the flowmeter mainly relies on the built-in battery or an external power supply as the power supply mode, and there is a problem that it is inconvenient to replace the battery regularly or set up an extern...
