Abstract
The invention discloses an alarm device capable of preventing people from getting lost. The alarm device comprises a transmitting device carried by an easily-lost object, and a receiving device carried by an accompanying person, wherein the transmitting device comprises a frequency generator and a wireless transmitter which are connected with each other; the frequency generator generates a signal with a specific frequency, and transmits out the signal through the wireless transmitter; the receiving device comprises a wireless receiver, a controller and an alarm; the wireless receiver receives the signal transmitted by the wireless transmitter, and sends the signal to the controller; and when the distance between the wireless transmitter and the wireless receiver is beyond a signal transmission range, the wireless receiver cannot receive the signal and the controller starts up the alarm. The alarm device can give out an alarm signal when the easily-lost object walks far away.
Description
Technical field
The present invention relates to a kind of communication device, particularly a kind of anti-warning device of wandering away.
Background technology
Father and mother carry small children son while going out at ordinary times, most of energy is all used in to be looked after with it child, when going shopping, father and mother often can not check the commodity of oneself liking heartily, once and father and mother's diversion arrives commodity, child is easy to walk alone far father and mother's discovery by the time because father and mother ignore own, evening while being often, too late to repent.
Not just father and mother's son that carries small children is gone out, some aged old man also often can separate with companion because of unfamiliar condition or people around too much, there are on the market at present a variety of old men of preventing, the device of child or amentia people lost, as the object of easily wandering away at these is installed GPS with it, when finding that they walk to miss the season, can be by sending request signal to GPS, receive the positional information that GPS sends, but these are all passive measures, particularly when child leaves father and mother when far away, be easy to by lawless people, be kept a close watch on again, even if obtain positional information now, also be often futile tracking, if again child's GPS device is with it removed, be difficult to find again.Therefore there is defect in current anti-wander-away device, haves much room for improvement.
Summary of the invention
Object of the present invention, is to provide a kind of anti-warning device of wandering away, and it can send alerting signal when the object distance of easily wandering away is far away, changes from passive to active.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of anti-warning device of wandering away, comprise the dispensing device being carried by the object of easily wandering away and the receiving trap being carried by retinue, wherein, dispensing device comprises interconnective frequency generator and wireless launcher, frequency generator produces the signal of characteristic frequency, and by wireless launcher, this signal is sent;
Described receiving trap comprises wireless receiver, controller and alarm, and wherein, wireless receiver receives the signal that aforementioned wireless launcher sends, and sends into controller; When wireless launcher and wireless receiver distance exceeds signal transmission ranges, wireless receiver does not receive signal, and controller starts alarm.
The frequency that said frequencies transmitter produces signal is 10MHz～40MHz.
Above-mentioned alarm adopts hummer.
Above-mentioned alarm adopts electromagnetic shaker.
Above-mentioned wireless launcher also connects GPS, and controller also connects display, and the positional information that wireless launcher gathers described GPS sends to wireless receiver, by wireless receiver, sends into controller, and controller is sent this positional information into display and shown.
Adopt after such scheme, the present invention utilizes wireless signal frequency higher, the principle that transmission range is shorter, by wireless transmitter is set, once easily wander away, to leave retinue more remote for object, will initiatively send alerting signal, prompting retinue finds, the measure of can taking the initiative on the one hand, in the very first time prevent from the wandering away generation of phenomenon, on the other hand, retinue that it(?) will full energies when going out be placed on nurse yet and easily wanders away on object, and can attentively check the commodity of oneself liking, kill two birds with one stone.
Accompanying drawing explanation
Fig. 1 is integrated stand composition of the present invention.
Embodiment
Below with reference to accompanying drawing, technical scheme of the present invention is elaborated.
As shown in Figure 1, the invention provides a kind of anti-warning device of wandering away, comprise dispensing device and receiving trap, introduce respectively below.
Dispensing device comprises interconnective frequency generator and wireless launcher, and described frequency generator produces the signal (as 10MHz～40MHz) of characteristic frequency, and by wireless launcher, this signal is sent.
Receiving trap comprises wireless receiver, controller and alarm, and wherein, wireless receiver and aforementioned wireless launcher are realized radio communication, and this wireless receiver can only receive the signal of described characteristic frequency, and the signal of reception is sent into controller; Described controller is realized the control to alarm according to the reception condition of signal, when distant between wireless launcher and wireless receiver, the transmission range that exceeds this characteristic frequency, now wireless receiver does not receive the signal that wireless launcher sends, controller starts alarm, sends alerting signal.
Described alarm can adopt hummer or electromagnetic shaker, or adopts hummer and electromagnetic shaker simultaneously, adopts sound and vibrations to report to the police simultaneously, prevents from cannot hearing chimes of doom because environment is noisy.
During use, dispensing device can be carried by the object of easily wandering away, and retinue carries receiving trap, setpoint frequency generator produces the frequency of signal, because frequency is higher, transmission range is shorter, therefore can set upper frequency according to actual conditions, as when frequency is 10MHz, transmission range is about 7m, and when frequency is increased to 40MHz, transmission range is only 2m left and right; Frequency generator continues to produce wireless signal, by wireless launcher, is sent; When two people's close together, wireless receiver can receive this wireless signal, and delivers to controller, now alarm being failure to actuate; Once and that the object of easily wandering away leaves retinue is far away, wireless receiver does not receive the wireless signal of characteristic frequency, and controller starts alarm, reminds retinue to note, can, in the very first time confirm easily the to wander away position of object, prevent trouble before it happens like this.
In addition, in the present embodiment, in order further to strengthen operability, described wireless launcher is also connected with GPS, and controller in receiving trap is connected with display, in wireless transmission process, the positional information that wireless launcher can gather GPS simultaneously sends to wireless receiver, to send into display and shows, in order reducing costs by controller after being processed, controller can just be controlled more new data of display at set intervals, as interval 5s～30s; When concrete application, once easily wander away, object leaves predeterminable range, and this Time Controller no longer can receive positional information, and control display, shows all the time the positional information finally receiving, can contribute to the rapid confirmation object position of easily wandering away, thereby conveniently find.
Above embodiment only, for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought proposing according to the present invention, and any change of doing on technical scheme basis, within all falling into protection domain of the present invention.
