Described terminal receiving equipment is mobile phone or host computer.
Described alarm is arranged on described terminal receiving equipment.
After adopting such scheme, a kind of empty nestor's situation of the present invention is monitored and early warning system in real time, utilize fiber-optic probe system to detect the vibration signal of current in family's feed pipe, Real-time Obtaining domestic water time and use the water period, and compare with the water period with the use water time of the empty nestor's normal condition defaulted in signal processing circuit, if use water data exception relatively, then signal processing circuit exports control signal, this control signal is sent to terminal receiving equipment by radio transmitter, control alarm by terminal receiving equipment to report to the police, household or other people then can judge whether empty nestor meets accident and cause with water abnormal thus.The present invention utilizes the domestic water time dexterously and carries out the method monitored with the water period; by with the just conventional water time of presetting be real time contrast with the water period; and then meet accident empty nestor and cause with the abnormal alarm of water; thus the fortuitous event of old man can be processed in time, improve the protection to empty nestor.Empty nestor's situation of the present invention is monitored and early warning system in real time, and cost is low, there is not monitoring dead band, and empty nestor can not be allowed to produce monitored uneasy sense, can not affect the normal life of old man completely.
Accompanying drawing explanation
Fig. 1 is circuit theory schematic block diagram of the present invention.
Embodiment
A kind of empty nestor's situation of the present invention is monitored and early warning system in real time, as shown in Figure 1, comprises fiber-optic probe system 1, signal processing circuit 2, radio transmitter 3, terminal receiving equipment 4 and alarm 5.
Fiber-optic probe system 1 comprises optical fiber source 11, coupling mechanism 12, optical fiber 13, first light power meter 14 and the second light power meter 15, optical fiber 13 is wrapped on the outer wall of family's feed pipe, and one end butt coupling device 12 of optical fiber 13, the other end connects the input end of the first light power meter 14, it is inner that the light beam that optical fiber source 11 is launched enters into optical fiber 13 by coupling mechanism 12, and the input end of the second light power meter 15 is directly connected with optical fiber source 11.
The output terminal of the first light power meter 14 and the second light power meter 15 is connected to the respective input of signal processing circuit 2 respectively, the output terminal of signal processing circuit 2 connects the input end of radio transmitter 3, the signal that radio transmitter 3 is launched is received by terminal receiving equipment 4, and the output terminal of terminal receiving equipment 4 connects alarm 5.
Fiber-optic probe system 1 for measuring the vibration signal of family's water supply in-pipe flow and being converted into electric signal, Real-time Obtaining domestic water time and use the water period.Particularly, it is inner that the light beam that optical fiber source 11 is launched enters into optical fiber 13 by coupling mechanism 12, this light beam is when optical fiber 13 internal transmission, the vibration signal of family's feed pipe can be converted to the change of light beam light intensity, record the situation of change of light intensity in optical fiber 13 by the first light power meter 14 and be converted into electric signal, second light power meter 15 directly obtains the light beam light intensity of optical fiber source 11 and is converted into electric signal, and the first light power meter 14 and the second light power meter 15 export corresponding electric signal respectively and compare to signal processing circuit 2.
Signal processing circuit 2 can adopt the signal processing circuit of existing routine, be preset with in it empty nestor's normal condition with the water time with water period (normal condition fiber-optic probe system 1 can be adopted normally to gather with during water in family with the water time with the water period), during work, signal processing circuit 2 receives the electric signal from the first light power meter 14 and the second light power meter 15 respectively, when the electric signal that the first light power meter 14 exports is different from the electric signal that the second light power meter 15 exports, then judge that the water in feed pipe is flowing, when the electric signal that the first light power meter 14 exports is identical with the electric signal that the second light power meter 15 exports, then judge that the water in feed pipe is static, thus the flowing water situation obtained in family's feed pipe, and with the water time with use the water period, and by this with the water time with water period and the comparing with the water time with the water period of empty nestor's normal condition of presetting in it, and output judges that data are to radio transmitter 3.
