A wave detecting plate is arranged inside the coat, which comprises an antenna, a wave detecting circuit used to detect strong electromagnetic radiation, an alarming device and a power supply connected to the wave detecting circuit; the antenna is connected to the input terminal of the wave detecting circuit, the alarming device is connected to the output terminal of the wave detecting circuit. The utility model provides a watch with the function of detecting the electromagnetic radiation.
Description
(1) technical field
The utility model relates to a kind of multi-functional wrist-watch.
(2) background technology
Electric field and magnetic field all are a kind of forms that material exists.Electromagnetic wave is the electromagnetic field of propagating with the form of ripple in the space.Electromagnetic energy is called electromagnetic radiation by vibration source to the process of propagating with the form of ripple all around.Reflected by human body skin behind the electromagenetic wave radiation human body or be absorbed by the body, cause injury easily human body.
Mobile phone can produce high-frequency energy before access failure, the people is known from experience the certain harmful effect of generation, especially for some special populations such as old man, pregnant woman, preferably in time find the scope that exists of mobile phone electromagnetic wave, avoid at frequency electromagnetic waves regional activity (mobile phone that comprises oneself certainly), existing wrist-watch does not possess the function that detects electromagnetic radiation.
(3) summary of the invention
Do not have the deficiency that detects the electromagnetic radiation function in order to overcome existing wrist-watch, the utility model provides a kind of wrist-watch that detects the electromagnetic radiation function that has.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of wrist-watch with detection electromagnetic wave function, comprise shell, watchband, wrist-watch module, the detection plate is installed in the described shell, described detection plate comprises antenna, is used to detect detecting circuit, alarm device and the power supply of strong electromagnetic radiation, described power supply connects detecting circuit, described antenna connects the input end of detecting circuit, and the output terminal of described detecting circuit connects alarm device.
Further, described detecting circuit is a tuned circuit, described tunable circuit comprises tuning capacity C1, coupling transformer T, detector diode D, filter capacitor C2, and the side of described tuning capacity C1 and coupling transformer T also is unified into resonant tank, and described antenna is connected on the resonant tank; The opposite side of described coupling transformer T and detector diode D, filter capacitor C2 form the loop, and described alarm device is in parallel with filter capacitor C2.
Further again, described tuning capacity C1 is a variable capacitance.Described power supply also connects the wrist-watch module.
Described alarm device is Vib., illuminator or loudspeaker.
Principle of work of the present utility model is: when the electromagnetic frequency that will receive as frequency and we of tuned circuit is identical, electric resonance will take place in tuned circuit, according to the prompting of alarm device, we just can check the existence of electromagenetic wave radiation.As the signal of detection of handset, when phone, detect the cell phone incoming call signal, alarm device sends warning information, again near answering, can lower the infringement that electromagnetic wave brings greatly after mobile phones such as prompting user are connected.
The beneficial effects of the utility model mainly show: 1, detect various electromagnetic radiation functions; 2, as decorating, improve environment and mood; 3, the reception of prompting mobile telephone set information can guarantee the mobile phone short message that discovery in time receives.
(4) description of drawings
Fig. 1 is the structural representation with the wrist-watch that detects the electromagnetic wave function.
Fig. 2 is the schematic diagram of detecting circuit.
Fig. 3 is the circuit diagram of detecting circuit.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of wrist-watch with detection electromagnetic wave function, comprise shell 1, watchband 2, wrist-watch module 3, in the described shell 1 the detection plate is installed, described detection plate comprises antenna, is used to detect the detecting circuit of strong electromagnetic radiation, alarm device 4 and power supply, described power supply connects detecting circuit, and described antenna connects the input end of detecting circuit, and the output terminal of described detecting circuit connects alarm device.
Detecting circuit is a tuned circuit, described tunable circuit comprises tuning capacity C1, coupling transformer T, detector diode D, filter capacitor C2, the side of described tuning capacity C1 and coupling transformer T also is unified into resonant tank, and described antenna is connected on the resonant tank; The opposite side of described coupling transformer T and detector diode D, filter capacitor C2 form the loop, and described alarm device is in parallel with filter capacitor C2.Tuning capacity C1 is a variable capacitance.Described power supply also connects the wrist-watch module.Alarm device 4 is Vib., illuminator or loudspeaker.
Power supply (BATTERY) is the 3V direct supply, and tuning capacity C1 is 0.72～3.42pF, and the inductance of the side of transformer T is 0.01uH, and filter capacitor C2 is 270 pF; This circuit parameter can detect regular handset, detects frequency range at 869～1880MHz, and the effective range of test is at 1.0～1.5 meters.
Its course of work is: as the signal of detection of handset, when phone, detect the cell phone incoming call signal, detecting circuit detects signal output, alarm device sends warning information, again near answering, can lower the infringement that electromagnetic wave brings greatly after mobile phones such as prompting user are connected.
Detecting circuit mainly is made up of detector diode D and filter capacitor C2.The detector diode effect: diode has unilateral conduction, promptly only allows the electric current of a direction to pass through, and the high frequency exchange current becomes unidirectional pulsating current after by diode, and this unidirectional current had both contained radio-frequency component, also contained low frequency (audio frequency) composition.The effect of filter capacitor: electric capacity has can make radio-frequency component pass through, the effect that stops low-frequency component to pass through, the radio-frequency component of pulsating current passes through from filter capacitor C2, and low frequency (audio frequency) electric current passes through alarm device, as alarm device is loudspeaker, and the vibrating reed that makes loudspeaker is with the signal vibration sounding.
