Below describe in detail break line type multi-usage alarm device of the present invention necessity involved in implementation process, guardian technique content.
Summary of the invention
Goal of the invention and beneficial effect: break line type multi-usage alarm device of the present invention looks for another way, it solves or compensate for the shortcoming that some supervising device on the market exists.It can be used for the anti-theft monitoring of indoor and outdoor valuables, can be cut off by people at connecting line of setting up defences, break, pipe when pulling apart alarm, be applicable to shop door and window, warehouse, office, setting up defences of the colony houses such as market shutter door, air-conditioner outdoor unit, electric motor car, oxen and horses sheep, and the place such as guardrail, mountain forest, orchard, fish (crab) pool prevents stranger from invading, and avoids unnecessary damage to property.Alarm device can draw a wires, and extension line can extend, and around protection place, by extension line through being closed by end points after article, or can be connected on metal, to be piped immediately alarm once extension line touches disconnected alarm device.It has practical, applied widely, and this alarm device is the anti-theft alarm device that a kind of thief cannot destroy.
Circuit working principle: the circuit of break line type multi-usage alarm device is about the multi-resonant oscillating circuit of 3KHz by time base circuit IC1 (NE555), resistance R1, resistance R2, electric capacity C1 component frequency, after circuit ON 9V direct supply, when connecting line between detection terminal TX1 and detection terminal TX2 is normal, the condition of work of multi-resonant oscillating circuit is destroyed, and piezoelectricity singing piece HA does not work.When connecting line between detection terminal TX1 and detection terminal TX2 is disconnected, multi-resonant oscillating circuit is started working, and piezoelectricity singing piece HA sends sound alarm.
When 9V direct supply is connected, if the line between detection terminal TX1 and detection terminal TX2 be in connect and interrupteur SW of setting up defences is off state time, alarm device is in standby armed state; When the door is opened, alarm device starts alarm; Closed line alarm device of setting up defences between interrupteur SW or connection detection terminal TX1 and detection terminal TX2 quits work.When direct current power source voltage is 9V, standby current is about 2mA, and during work, electric current is about 8mA.
Technical scheme: break line type multi-usage alarm device, it comprises 9V direct supply, sets up defences and circuit of withdrawing a garrison, multi-resonant oscillating circuit and phonation circuit, it is characterized in that:
Set up defences and circuit of withdrawing a garrison: it is made up of interrupteur SW of setting up defences, detection terminal TX1 and detection terminal TX2, connecting line of setting up defences, 2nd pin of a termination detection terminal TX1 of connecting line and the timely base IC circuit 1 in one end of interrupteur SW of setting up defences of setting up defences and the 6th pin, detection terminal TX2 meets the other end of connecting line of setting up defences and the other end of interrupteur SW of setting up defences and circuit ground GND;
Multi-resonant oscillating circuit and phonation circuit: it is by time base circuit IC1, resistance R1, resistance R2, electric capacity C1 and piezoelectricity singing piece HA forms, the model that time base circuit IC1 selects is NE555, 4th pin of time base circuit IC1 and the 7th pin connection circuit positive pole VCC, 2nd pin of time base circuit IC1 and the 6th pin connect one end of electric capacity C1 and one end of resistance R1, the other end connection circuit positive pole VCC of resistance R1, 1st pin of time base circuit IC1 and the other end connection circuit ground GND of electric capacity C1, 8th pin of time base circuit IC1 is by resistance R2 connection circuit positive pole VCC, 3rd pin of time base circuit IC1 is by piezoelectricity singing piece HA connection circuit positive pole VCC,
9V DC power anode connection circuit positive pole VCC, 9V DC power cathode is connected with circuit ground GND and detection terminal TX2.
Accompanying drawing explanation
Accompanying drawing 1 is break line type multi-usage alarm device provided by the invention embodiment circuit working schematic diagram; Dotted line on accompanying drawing 1 is connecting line of setting up defences.
Embodiment
According to the break line type multi-usage alarm device circuit working schematic diagram shown in accompanying drawing 1 and accompanying drawing explanation, and according to annexation between components and parts in each several part circuit described in summary of the invention, and components and parts technical parameter described in embodiment requires and circuit production main points are carried out enforcement and can be realized the present invention, is further described correlation technique of the present invention below in conjunction with embodiment.
The technical parameter of components and parts and selection requirement
IC1 is time base circuit, and the model selected is NE555 or LM555, and packing forms is dual inline type 8 pin; Each pin function: the 1st pin connection circuit ground GND; 2nd pin is trigger end; 3rd pin output terminal; 4th pin preset end; 5th pin is control voltage; 6th pin thresholding (threshold value); 7th pin is discharge end; 8th pin connection circuit positive pole VCC;
The resistance of resistance R1 is 200K Ω; The resistance of resistance R2 is 100K Ω;
C1 is electric capacity, and use capacity is the ceramic disc capacitor of 0.01 μ F;
HA is piezoelectricity singing piece, diameter ￠ 42mm, acoustic maximum intensity >=100dB, and the diameter of piezoelectricity singing piece can not be less than 30mm, otherwise the responding range of frequency will be affected.
The making main points of circuit, circuit debugging and using method
Because the circuit structure of break line type multi-usage alarm device is fairly simple, generally, as long as the electronic devices and components performance selected is intact, and the components and parts annexation to specifications in accompanying drawing 1 is welded, physical connection line and welding quality are through carefully checking correctly, and circuit of the present invention only needs to debug simply and can normally work;
1. detection terminal TX1 and detection terminal TX2 is fixed on a limit, connecting line (contact) of setting up defences is fixed on doorframe, interrupteur SW of setting up defences is arranged on more hidden place, and first close when owner opens the door and set up defences interrupteur SW to remove alarm function, alarm device can not work; When people needs to leave time, then interrupteur SW of setting up defences is disconnected, recover alarm function;
2. market shutter door is antitheft: connecting line two ends of setting up defences are connected to detection terminal TX1 and detection terminal TX2 respectively, form loop when putting down shutter door, when there being people by shutter door pull-up 1cm, alarm device will send loud piping, frighten uninvited guest away, thus protect the safety of indoor property;
3. outdoor machine of air-conditioner is antitheft: can be fixed on two screws of air-conditioner outdoor unit diverse location by connecting line two ends of setting up defences, guarantee that between this two places screw, conduction is good, interrupteur SW of setting up defences pushes open position, dismantling air-conditioner outdoor unit when there being people will cause connecting line of setting up defences to disconnect, and now indoor alarm device will pipe alarm;
4. electric vehicle anti-theft: rim connecting line of setting up defences being passed bicycle or motorcycle, connecting line of setting up defences again is connected to detection terminal TX1 and detection terminal TX2 respectively, make it to form closed-loop path, and interrupteur SW of setting up defences pushes open position, when have people steal car break set up defences connecting line time, alarm device will pipe alarm.
Circuit components layout of the present invention, circuit structure design, its shape and size etc. of outward appearance are not all gordian techniquies of the present invention; neither application claims protection technology contents; because not affecting specific implementation process of the present invention, therefore do not illustrate one by one in the description.
