Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention program is described in detail.
Embodiment 1
The indoor alarm equipment that the present embodiment provides, is located on the windowsill of indoor.As shown in Figure 1 and Figure 2, this indoor alarm equipment mainly forms by being provided with the housing of three through holes, photoelectric sensing unit, signal processing unit, buzzer and DC source.Photoelectric sensing unit, signal processing unit and buzzer are respectively arranged in housing.Photoelectric sensing, buzzer communicate to connect with signal processing unit respectively, and photoelectric sensing unit, signal processing unit and buzzer are powered by above-mentioned DC source.The housing that the present embodiment provides be a closing, inside be provided with the cube of cavity structure.The magnitude of voltage of the DC source of the present embodiment is+5V.
Above-mentioned housing is fixed on windowsill by gluing sheet, and the length direction of housing is parallel with windowsill, sees Fig. 3.
Through hole on housing is sequentially distributed the top at housing along shell length direction equally spacedly, sees Fig. 1.Three holes are followed successively by the first through hole, the second through hole and third through-hole from left to right.
Photoelectric sensing unit is mainly made up of laser instrument, two light sensitive diodes and fixed value resistance.Laser instrument, two light sensitive diodes correspond to the position directly below of through hole in being respectively arranged on housing.Laser instrument is opened and closed by an on-off control.The negative pole of light sensitive diode connects DC source respectively, and positive pole is respectively correspondingly by fixed value resistance ground connection.Through hole in an intermediate position in three through holes, the i.e. second through hole be arranged right below above-mentioned laser instrument.The laser instrument of the present embodiment uses conventional laser pen, and when laser pen works, the top of light spot to window frame, owing to being concentrated light, light will not scatter so, person thefted will not discovering so that walking around this alarm, having stronger disguise.Remaining two through hole be arranged right below light sensitive diode, be used for receiving thief when crossing windowsill, laser pen exposes to the trouser legs of thief, sole and the diffuse-reflectance light that formed.Light intensity in view of diffuse-reflectance light is the least, and the electric current that light sensitive diode passes through is less, thus the voltage signal produced is less, needs setting to be specifically designed to the signal amplification circuit amplifying this voltage signal.
The signal processing unit that the present embodiment provides mainly is made up of with the above-mentioned signal amplification circuit mentioned single-chip microcomputer.Two inputs of signal amplification circuit are corresponding with light sensitive diode respectively to be connected.Two outfans of signal amplification circuit connect the external interrupt interface of single-chip microcomputer respectively.
Such as Fig. 4, in the present embodiment, signal amplification circuit is LM358 type operational amplifier.Single-chip microcomputer is 89C51 type single-chip microcomputer, two inputs being connected respectively LM358 of two light sensitive diodes.Two outfans of LM358 are connected respectively external interrupt interface INT0, INT1 of 89C51 single-chip microcomputer.
As long as this indoor alarm equipment user opens above-mentioned switch, duty can be entered.The light beam of laser pen exposes to the top of window frame, often use the materials such as ceramic tile to lay due to the top of window frame, therefore light beam is that direct reflection will not reflex to second, third through hole, even if the top of window frame is metope material, owing to the top of window frame is relatively big away from this indoor alarm equipment distance, the faintest being difficult to of light after diffuse-reflectance is collected by the light sensitive diode below second, third through hole.When above burglary person passes the second through hole, owing to the health of the thief distance away from windowsill is less than 30cm, now laser pen is irradiated to thief's health thus the intensity of diffuse-reflectance light beam that causes be enough to be captured by diode form relatively low voltage signal, this voltage signal entered to be formed after the amplifying circuit of signal processing unit amplifies and enables signal and be sent to the external interrupt interface of 51 single-chip microcomputers, trigger and interrupt, thus the buzzer work that Micro Controller Unit (MCU) driving is attached thereto is with warning thief and prompting resident family.
Embodiment 2
The indoor alarm equipment that the present embodiment provides, is located on the windowsill of indoor.As shown in Figure 1 and Figure 2, this indoor alarm equipment mainly forms by being provided with the housing of three through holes, photoelectric sensing unit, signal processing unit, buzzer and DC source.Photoelectric sensing unit, signal processing unit and buzzer are respectively arranged in housing.Photoelectric sensing, buzzer communicate to connect with signal processing unit respectively, and photoelectric sensing unit, signal processing unit and buzzer are powered by above-mentioned DC source.The housing that the present embodiment provides be a closing, inside be provided with the cube of cavity structure.
Above-mentioned housing is fixed on windowsill by gluing sheet, and the length direction of housing is parallel with windowsill, sees Fig. 3.
The photoelectric sensing unit that the present embodiment provides is the circuit structure that is in parallel of two light sensitive diodes and a laser instrument.Laser instrument is opened by an on-off control, is user and controls the switch of this alarm work.The negative pole of light sensitive diode connects DC power cathode respectively, and the positive pole of light sensitive diode is connected with signal processing unit, sees Fig. 5.
Through hole on housing is sequentially distributed the top at housing along shell length direction equally spacedly, sees Fig. 1.Three holes are followed successively by the first through hole, the second through hole and third through-hole from left to right.Through hole in an intermediate position in three through holes, the i.e. second through hole be arranged right below above-mentioned laser instrument.The laser instrument of the present embodiment uses conventional laser pen, and when laser pen works, the top of light spot to window frame, owing to being concentrated light, light will not scatter so, person thefted will not discovering so that walking around this alarm, having stronger disguise.Remaining two through hole be arranged right below light sensitive diode, be used for receiving thief when crossing windowsill, laser pen exposes to the trouser legs of thief, sole and the diffuse-reflectance light that formed.
Further, signal processing unit is a relay.The two ends of the coil of this relay connect the input of photoelectric sensing unit respectively and form control loop with outfan, and the movable contact of relay connects the two ends of buzzer respectively and forms controlled loop, sees Fig. 5.
The indoor alarm equipment of the present embodiment is after user opens, when having thief to stride across above windowsill night, owing to the health of the thief distance away from windowsill is less than 30cm, now laser pen is irradiated to thief's health thus the intensity of diffuse-reflectance light beam that causes be enough to be captured by diode, the diode of reversal connection is become conducting from cut-off state, thus the coil of relay has electric current to pass through, iron core is made to produce the armature of magnetic force band motor type relay, the contact making relay is pulled to movable contact by stationary contact, so that controlled circuit conducting, buzzer works.
