Abstract
A kind of wireless power direct-reading water meter word-wheel box, comprise shell, described shell is provided with installs storehouse, mounting circuit board mount in storehouse is installed, circuit board is arranged on below circuit board support, and character wheel acquisition module is housed above circuit board support, above character wheel acquisition module, character wheel is housed, described circuit board is connected with character wheel acquisition module, power supply receiving coil, infrared transceiver module, and described shell is by top seal.Without the need to the character wheel box of built-in power or outside wired power supply, only when water meter reading, Usage data collection device is powered to water meter by the mode of wireless power, the electric energy that water meter internal circuit uses collector to provide reads the reading of current water meter and is uploaded to collector, the utility model adopts mechanical seal to vacuumize and installs with extraneous without any mechanical interface, without any need for electric energy when not checking meter, thus it is long or power to water meter that wiring cost is higher, the problem of poor reliability to avoid internal battery serviceable life.
Description
Technical field
The utility model relates to a kind of water metering outfit, particularly a kind of wireless power direct-reading water meter word-wheel box.
Background technology
At present, direct-reading water meter is on the market all adopt the mode of powered battery or wired power supply to realize, adopt battery powered direct-reading water meter by the restriction of battery capacity, substantially within several years, just there will be electricity deficiency afterwards in use and cause job insecurity or inoperable phenomenon, and make battery-powered direct-reading water meter because under being in electriferous state for a long time, easily cause that peripheral chip is aging to break down; A class is also had to be the wired power supply mode direct-reading water meter adopting external cabling, as M-BUS, RS485 direct-reading water meter, although adopt wired power supply to solve the problem of battery capacity, and water meter internal circuit is when being also no longer in always charged, but be that each block water meter cable laying cost high workload amount is large, and the cable laid is as easy as rolling off a log is subject to destruction that is artificial or other factors, causes water meter not use.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, propose a kind of need not internal battery or the external cabling wireless power direct-reading water meter word-wheel box of powering.Use the water meter of wireless power direct-reading water meter word-wheel box not need wiring to power, not by the restriction of mounting condition, and serviceable life is not also by the constraint of internal battery.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of wireless power direct-reading water meter word-wheel box, be characterized in: described wireless power direct-reading water meter word-wheel box comprises shell, described shell is provided with installs storehouse, mounting circuit board mount in storehouse is installed, circuit board is arranged on below circuit board support, character wheel acquisition module is housed above circuit board support, above character wheel acquisition module, character wheel is housed, described circuit board is connected with character wheel acquisition module, power supply receiving coil, infrared transceiver module, and described shell is by top seal.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, described top cover is provided with power supply coupling slot and data acquisition window, power supply receiving coil is arranged in power supply coupling slot, and infrared transceiver module is arranged on below data acquisition window.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and integrated monolithic machine, high-frequency rectification circuit, filtering circuit, mu balanced circuit on described circuit board, possess function high-frequency signal being converted to DC voltage.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and described power supply receiving coil is plane annular coiling.
The principle of work of wireless power direct-reading water meter word-wheel box described in the utility model utilizes electromagnetic induction principle, water meter top cover loads inductive coil, when data acquisition unit is near water meter receiving plane, high-frequency electromagnetic signal launched by internal wireless coil of powering, the inductive coil of water meter inside produces induction electromotive force, convert DC signal to by processes such as rectifying and voltage-stabilizings again and supply the internal circuits such as single-chip microcomputer, Single-chip Controlling character wheel acquisition module reads the state of current character wheel and gives single-chip microcomputer decoding and obtain current meter reading, meter reading is sent to data acquisition unit by infrared transceiver module by single-chip microcomputer again, data acquisition unit leaves water meter after having gathered data, because of high-frequency electromagnetic signal disappearance direct-reading water meter internal circuit also dead electricity thereupon, whole water meter only data acquisition unit near and just work on power when launching high-frequency electromagnetic signal, do not work at ordinary times, not electricity consumption, and be called wireless power, it is the indicating value directly reading current water meter during data acquisition, so be called direct-reading.Compared with prior art, advantage: 1. adopt wireless power, do not need internal battery or external cabling to power, reduce the cost and install complexity.2. almost any place can installing common water meter can be installed.3. long service life, does not retrain by factors such as power supplys.4. the direct actual indicating value of water-meter reading, avoids data to store corrupted or lost problem.
