Abstract
The utility model discloses a wireless flow meter triggered by water flow. The wireless flow meter triggered by water flow comprises a pulse signal transmitting base meter, a flow collection circuit, a wireless communication module, a triggering circuit, a power supply circuit and a high-capacity lithium battery, wherein the flow collection circuit is connected with the pulse signal transmitting base meter and the triggering circuit; the triggering circuit is connected with the power supply circuit; the high-capacity lithium battery is electrically connected with the power supply circuit; the signal end of the triggering circuit is connected with a wires communication module serial port; the wireless communication module is used for transmitting flow information to an external device through signals in ISM (Industrial Scientific Medical) frequency bands of 433MZH. The wireless flow meter triggered by water flow is in a dormancy state with low power consumption in the absence of the water flow; the power supply circuit triggered through water flow supplies power to the wireless communication module, so that the service life of the battery is prolonged; the wireless communication module is used for performing remote transmission of data; the wireless flow meter triggered by water flow can be mounted in places such as deep wells and some remote areas with high costs for wiring or replacing; meanwhile, managers can remotely obtain on-site flow data and history data in real time through a wireless manner.
Description
Affiliated technical field
The utility model belongs to metering field, relates to a kind of flow instrument, especially adopts the current trigger-type wireless flow meter of wireless communication technique.
Background technology
Flowmeter is widely used in the industries such as petroleum gas, petrochemical complex, water treatment, pharmacy, the energy, metallurgy, paper pulp papermaking and building materials, at present, traditional mechanical flowmeter is in the universalness stage, the electronic flow-meter rising is installed and is adopted on-the-spot Profibus PA bussing technique, wiring cost is large, and at deep-well or remote area, install, engineering complexity, differs and properly installs surely flowmeter.
Summary of the invention
The purpose of this utility model is to provide a kind of current trigger-type wireless flow meter, the wireless flow meter that adopts the ISM band signal data transmission technology of 433MZH and turn round by water flow signal trigger circuit.
The utility model solves the technical scheme that its technical matters adopts: this current trigger-type wireless flow meter comprises pulse post a letter base table, flow collection circuit, wireless communication module, trigger circuit, power circuit and high-capacity lithium battery.Described flow collection circuit connects the pulse base table gauge outfit of posting a letter, described flow collection circuit is connected with trigger circuit, described trigger circuit are connected with power circuit, be responsible for triggering the unlatching of power circuit or closing, described high-capacity lithium battery is electrically connected with power circuit, be responsible for each branch road current/voltage is provided, described trigger circuit signal end is connected with wireless communication module serial ports.Described wireless communication module transfers to external equipment by the ISM band signal of 433MZH by flow information.When having current through out-of-date, by flow collection circuit, water flow signal is transferred to trigger circuit, making power circuit is wireless communication module power supply.
The beneficial effects of the utility model are: it is wireless communication module power supply that the pattern that this current trigger-type wireless flow meter triggers by current triggers power circuit, make wireless communication module energy remote transmission data, greatly shortened the time of wiring installation construction, simultaneously due to the larger wireless communication module just triggering work when having flow of power consumption, at ordinary times in dormant state, greatly extended high-capacity lithium battery serviceable life, changed battery number of times and greatly reduce.And infield is unrestricted, comprise deep-well and remote constructional difficulties, the place of replacing battery difficulty, meanwhile, managerial personnel can pass through data on flows and the historical data at the long-range Real-time Obtaining of wireless mode scene.
