Abstract
The utility model relates to a long-wavelength standard wave re-radiation antenna device, belonging to the electronic field of the science and technology. The object of the utility model is to re-emit a long-wavelength standard wave in an approximate non-directional emitting way using the small movable antenna device. Thus a wave clock in areas without the coverage of the long-wavelength standard wave such as indoors, underground rooms and garages can receive the long-wavelength standard wave. An annular antenna is composed of a coil wound on the outer edge of a frame and a resonance circuit in serial connection with a capacitor. A magnetic rod antenna is composed of a coil wound on a ferrite magnetic rod and a resonance circuit in parallel connection with the capacitor. The magnetic rod antenna is mounted on the middle horizontal level of the annular antenna and inclines by some angles along the horizontal direction, so as to obtain the relatively strong magnetic field intensity and re-emit the long-wavelength standard wave.
Description
Technical field
The utility model relates to a kind of automatic constantly long wave standard wave of revising radiating antenna device again that is used to carry out, and ranges radio transmission and reception technique, belongs to the electronics technology field.
Background technology
Radio wave clock is the high-tech product of new generation after quartz electronic clock and watch, and the new mileage of time measurement has been opened up in its appearance.China built up the testing stand that can work 6.5 hours every day in 1999, and (50KW all solid-state transmitter, tranmitting frequency 68.5KHZ), completion in 2000 is piloted and the part field testing.Cooperated with Xi'an Gaohua Technology Co., Ltd. at national time service center in 2007; Shangqiu City has been set up the special-purpose BPC low-frequency time-code of 100KW radio controlled timepiece broadcast platform in Henan; Thereby electric wave signal has covered Chinese most of areas; Can use the time code that is received to settle the standard constantly, can revise clock in view of the above automatically constantly.
But, because the wavelength of long wave standard wave is longer, thereby be difficult to propagate into inside such as building, be arranged at and the radio wave clock of basement is difficult to receive standard wave, to such an extent as to can't revise the moment automatically in the building in.In order to address this problem, the utility model proposes a kind of automatic constantly long wave standard wave of revising radiating antenna device again that is used to carry out.The roof of the building to set the external antenna to receive long-wave standard radio wave, the received signal to the laying of the cable, sent to the building layers of each chamber, and by installing the indoor and compact antenna device for re-radiation.
Summary of the invention
The utility model proposes a kind of automatic constantly long wave standard wave of revising radiating antenna device again that is used to carry out; Its goal of the invention is: in order to let the radiation of long wave standard wave; Enter into each chamber of each layer in the building, satisfy the needs of radio wave clock acceptance criteria electric wave, and with its antenna miniaturization; Removableization design is met the need of market and client's needs.
In order to realize the foregoing invention purpose: the utility model proposes a kind of automatic constantly long wave standard wave of revising radiating antenna device again that is used to carry out, and it is by framework, loop coil, ferrite bar magnet, bar magnet coil, capacitor, and binding post is formed; Framework is an insulator, and the framework outer side edges forms loop aerial along being wound with coil; Coil and capacitors in series; Form the loop through the binding post external circuit, the central horizontal position is provided with the ferrite bar magnet in the framework, is wound with coil on the bar magnet; Form magnetic rod antenna, the parallelly connected formation of coil loop with capacitor.
Further refinement analysis:
Said framework is processed by insulating material; The framework outer side edges is along being wound with coil, and the direct line terminals of a toroidal end is after the other end and the capacitors in series; Be connected with external circuit through binding post; Form series resonant circuit, when having alternation long wave standard signal to flow through in the loop coil, will produce alternating magnetic field around the coil.
Said ferrite bar magnet for high permeability material is processed, is wound with some coils on the bar magnet, the coil two ends are formed the closed-loop path through the frequency range diverter switch with capacitor, form antiresonant circuit.Because the diffusion of loop aerial peripheral electromagnetic field; Make ferrite bar magnet and bar magnet coil produce induced field on every side; And the diffusion again of induced field; Just more strengthened the magnetic field intensity between loop aerial and the ferrite magnetic rod antenna, under the condition of the parallel resonance of the series resonance of loop coil and capacitor and ferrite bar magnet coil and capacitor, finally formation is resonated.
Described in the parallel resonance closed-loop path of magnetic rod antenna, coil and capacitor; Again and link the series circuit of a light-emitting diode and current-limiting resistance; In the parallel resonance closed-loop path of magnetic rod antenna, coil and capacitor; Sense electric wave signal and when producing induction field, understand some induced current to form the loop the bright lamp of light-emitting diode this moment through current-limiting resistance and light-emitting diode; Prove that with this magnetic rod antenna loop has the induced field of electric wave signal, radiation function is effectively more also to prove electric wave signal simultaneously.
Have access to one group of frequency range diverter switch respectively in said series loop and magnetic rod antenna, coil and the capacitor shunt circuit at loop aerial, coil and capacitor, it act as back-up circuit.First, when there is fault in former loop, switch to back-up circuit through switch.Second, when newly-increased frequency is offered at national time service center, can select through switch, switch to another frequency (only needing capacity with series capacitance and shunt capacitance elect in addition gets final product).Because the electric capacity of single ideal capacity is difficult to apolegamy, form with a plurality of shunt capacitances in the circuit.
The principal character of this antenna assembly is; With the loop aerial that transmission signal relative and emission again is resonated; With the direction of the magnetic direction quadrature of this loop aerial some directions that tilts,, this antenna assembly is configured in this loop aerial as the mode of magnetic direction; Comprise and the magnetic rod antenna that sends signal resonance, make electric field strength become roughly non-direction antenna assembly by loop aerial and magnetic rod antenna.
Owing in loop aerial, be provided with magnetic rod antenna; And bar magnet adopts high permeability material to process; When flowing through electric wave signal in the loop aerial, because electromagnetic induction principle produces a large amount of induced fields around magnetic rod antenna; And this induced field direction is consistent with the loop aerial magnetic direction, forms resonance.Along with the aggravation of resonance, field intensity constantly increases, and still, whether magnetic density distributes even, on magnetic field distribution figure, has depression points through the experiment proof.Because the magnetic rod antenna receiving feature has directivity, for this direction and gradient to magnetic rod antenna slightly adjusts, just can change magnetic direction, plays the effect that remedies the magnetic density skewness and cause depression points.Thereby can obtain combination variation in magnetic field between loop aerial and the magnetic rod antenna, the optimum position of resonance frequency generation electric field strength.
