Description
Affiliated technical field
The utility model relates to a kind of magnetic induction power supply to direct-reading electronic water meter or gas meter power supply.
Background technology
At present, direct-reading electronic water meter or gas meter are divided into wired and wireless topology.Wired direct-reading aqueous vapor/table needs lead to be connected between its table tool and meter reading instrument, and the working power of table tool is provided by meter reading instrument, exists to install to bother unhandy problem.Wireless direct-reading aqueous vapor/table does not have lead to be connected between its table tool and meter reading instrument, and easy to operate though installation is simple, the table tool needs power autonomous, no matter is employing AC power or battery, and inconvenience is all arranged; If adopt AC power, not only construction is complicated, but also exists potential safety hazard; If adopt battery, use cost height not only then, and also old and useless battery treatment is improper, also can produce the pollution of soil and groundwater resources.
Summary of the invention
For overcoming the deficiencies in the prior art part, the utility model provide a kind of rational in infrastructure, install simple, easy to operate, with low cost, be specially adapted to the magnetic induction power supply of powering to direct-reading electronics aqueous vapor/table.
The technical scheme that its technical problem that solves the utility model adopts is: comprise emitter and receiving system, emitter comprises AC signal generator, AC signal power amplifier and the transmitting coil that links to each other successively, and receiving system comprises receiving coil, rectification circuit, filter circuit and the voltage stabilizing circuit that links to each other successively.
During use, emitter is loaded in the meter reading instrument; Receiving system is loaded in direct-reading electronics water (or gas) table, and its circuit output end of pressure-stabilizing links to each other with the data processing equipment of water meter.When making a copy of, start emitter, AC signal generator produces alternate electrical signal, and this alternate electrical signal is after the AC signal power amplifier carries out power amplification, by transmitting coil emission alternating magnetic field.Under the effect of alternating magnetic field, the two ends of the receiving coil of receiving system produce the alternating voltage of same frequency, this voltage is after rectification circuit and filter circuit carry out rectification, filtering, form dc pulse moving voltage, behind voltage stabilizing circuit, become direct voltage again, this direct voltage is the data processing equipment powered operation of direct-reading electronic water meter, directly demonstrates the numerical value of water meter on the meter reading instrument.
The beneficial effects of the utility model are: rational in infrastructure, install simple, easy to operate, be particularly suitable for working power as direct-reading electronics water/gas meter, reduced the labour intensity of the person of checking meter, improved operating efficiency, and it is with low cost, be suitable for to promote the use, have good economic benefit and social benefit.
Description of drawings
Fig. 1 is the electrical installation schematic diagram of the utility model embodiment.
Among the figure: 1 is that AC signal generator, 2 is that AC signal power amplifier, 3 is that transmitting coil, 4 is that receiving coil, 5 is that rectification circuit, 6 is that filter circuit, 7 is a voltage stabilizing circuit.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model comprises emitter and receiving system, and emitter comprises AC signal generator 1, AC signal power amplifier 2 and transmitting coil 3, and above-mentioned AC signal generator 1, AC signal power amplifier 2 and transmitting coil 3 link to each other successively; Receiving system comprises receiving coil 4, rectification circuit 5, filter circuit 6 and voltage stabilizing circuit 7, and above-mentioned receiving coil 4, rectification circuit 5, filter circuit 6 and voltage stabilizing circuit 7 link to each other successively.
During use, emitter is loaded in the meter reading instrument; Receiving system is loaded in direct-reading electronics water (or gas) table, and its voltage stabilizing circuit 7 outputs link to each other with the data processing equipment of water meter.When making a copy of, start emitter, AC signal generator 1 produces alternate electrical signal, and this alternate electrical signal is after AC signal power amplifier 2 carries out power amplification, by transmitting coil 3 emission alternating magnetic fields.Under the effect of alternating magnetic field, the two ends of the receiving coil 4 of receiving system produce the alternating voltage of same frequency, this voltage is after rectification circuit 5 and filter circuit 6 carry out rectification, filtering, form dc pulse moving voltage, behind voltage stabilizing circuit 7, become direct voltage again, this direct voltage is the data processing equipment powered operation of direct-reading electronic water meter, directly demonstrates the numerical value of water meter on the meter reading instrument.
