Description
The utility model relates to a kind of warning device.
Warning device is widely used in every field the sixth of the twelve Earthly Branches.Chinese patent GG 86207070 discloses a kind of acoustic control burglar alarm, and it has sound-detection gear, a monitoring passage and the warning passage be made up of sonic transducer and note amplifier.
Chinese patent GG 86211018 discloses a kind of multifunction electronic alarming device, form by main frame and secondary machine, main frame has a signal monitoring circuit that comprises acoustic control, level, connection formula and breakaway-element measuring ability, and secondary machine has the potential monitoring circuit of an a certain voltage stabilizing value.The major-minor machine also respectively has a simulated sound warning circuit that sends at least two kinds of sound in turn.
Chinese patent GG 86209122 discloses another kind of wired burglar alarm, especially for the person of avoiding theft sled pound the door, the wired alarming device of window, safety cabinet and disconnection and the external circuit that kinks, its controlling alarm loop is controlled back by two and is formed.First control loop works when external circuit disconnects, and second control loop works when external circuit kinks.
Also have and utilize " touch ", ruddiness line, microwave, vibrations etc. to realize the device of reporting to the police.
The controlling alarm loop of above-mentioned burglar alarm and signal deteching circuit are generally comparatively complicated, and function is less, easily is damaged.
The purpose of this utility model provides a kind of multi-functional alarm, and signal detector is simple two metallic conductors; Alarm control circuit adopts simple relay; In sound and light alarm, can control output AC and/or direct current, for various consuming devices (for example sound/as uses such as the mechanical, electrical nets of videocorder, photography/resemble) power supply for exchanging and/or direct current and automaticallying switch; Can be used as burglar alarm, can report to the police as constant temperature, liquid level, boiling water, the control of catching fire again, can also be as electric bell, "electric cat" etc.
The utility model comprises signal detector (sensor), alarm control circuit, sound light alarming circuit, alternating current and/or parts such as direct current output mechanism and power supply.Signal detector adopts two metallic conductors, can be switched on or switched off.Alarm control circuit adopts a simple relay, relay line bag is connected with the two ends of signal detector, two groups of contacts guide sound optical alarm circuit and alternating current and/or direct current output mechanism are respectively arranged, and alternating current and direct current output mechanism are simple and easy supply socket.Power supply is established alternating current and/or direct current, controls its conversion automatically by relay, and Alternating Current Power Supply is made up of civil power, transformer and current rectifying and wave filtering circuit, and the line bag of AC and DC electricity switching relay is in parallel with current rectifying and wave filtering circuit.Sound light alarming circuit is established news Chinese percussion instrument and bulb.
If signal detector adopts two plain conductors, for example gummed wire, enameled wire etc., the anti-satellite line as burglar alarm is used can bury, be laid on wall, door and window or other the antitheft thing of buildings.Utilize plug, seat to be connected with the line bag of controlling alarm relay in anti-satellite line two ends.
If signal detector adopts a metallic conductor bar and a slice " U " shape metallic conductor sheet, when an end of this two metallic conductor is fixed on the insulant, can be used as the signal detector of thermostatic control, boiling water boiling warning, fire alarm etc.
In like manner, also can be used as fluid level controller.
The controlling alarm relay is in parallel with the current rectifying and wave filtering circuit of Alternating Current Power Supply.When signal detector is connected, the adhesive of controlling alarm relay, two groups of contacts are in normally open, at this moment do not report to the police, and the news Chinese percussion instrument does not ring, lamp does not work, and the AC and DC accessory power outlet is output not.When signal detector disconnects, the controlling alarm relay discharges, two groups of contacts are in normally off, at this moment report to the police, the buzzing of news Chinese percussion instrument, lamp is bright, and the AC and DC accessory power outlet has electric power output voltage, can drive other consuming device, for example sound/as videocorder, photography/resemble startup work such as mechanical, electrical net.
When AC power had a power failure, AC and DC electricity switching relay discharged, and two groups of contacts are converted to normally off from normally open, make direct supply connection work, guarantee the work of controlling alarm relay.When ac power supply, the current rectifying and wave filtering circuit in parallel with AC and DC electricity switching relay line bag has output, make relay work (adhesive) in parallel with it, two groups of contacts are converted to normally open from normally off, direct supply cuts off automatically, realizes the automatic conversion of AC and DC feed circuit.
The alarm that the utility model and the sixth of the twelve Earthly Branches have compares, and its signal detector and alarm control circuit are particularly simple, utilizes the switching of two metallic conductors and the suction of a little relay, the purpose of putting the realization warning and controlling.In addition, except that sound commonly used, light warning indication, when reporting to the police, also there is not the output of AC and DC electricity, for other standby electrical device sound/for example, to reach warning, control, prevent theft, field notes, to catch multiple purpose such as robber as startup work such as videocorder, photography/camera, electrical network, strong illumination lamps.Except as burglar alarm, electric bell, the "electric cat", also can be used as equipment such as thermostatic control, liquid level control, boiling water warning, fire alarm.Simultaneously, realized the automatic switchover of AC and DC power supply,, also can play the warning effect in case supply line is destroyed.The utility model than existing utilize alarms such as microwave, ruddiness line, " touch ", " vibrations ", photoelectricity, capacitive coupling simple, reliably, cost is low, function is many, is easy to popularization and application.
