The background of invention technology
At present, the smog alarm apparatus generally is furnished with power supply (as exchanging 240 volts), internal backup battery (as 9 volts of dc-batteries), Smoke Detection sensor unit (being generally photoelectricity or ionization design) and the acoustical generator that causes from the standard primary power.This class device has the terminal that connects primary power.
In heavy construction, generally have several dissimilar checkout equipments, such as smoke-detectors and thermal detector and the panalarm that is interconnected to the warning monitor board.This class warning monitor board monitors the detecting device in whole building, building usually, in case detect definite detection signal, monitor board just in time drives panalarm.Typical panalarm in the apartment is made up of the acoustical generator in the corridor, building of receiving monitor board, however this class warning system may be just centralized control by the warning monitor board just be driven.This class monitors that panel comprises expensive equipment, and installation and upkeep cost are generally very big.Because all command communications are by monitoring that panel starts, described system is also complicated, not really flexible.
Another problem that fire alarm system design person faces, be in the building (particularly apartment) not only wish can drive alarm on the ground that light detects fire, also wish to drive alarm, thereby the occupant will have necessary early warning in its oneself residence, room or unit in whole building, building.Early warning provides the extra time of withdrawing the building.Because the warning system in the apartment generally is made up of the acoustical generator in the corridor, building that is connected to monitor board, so especially when the occupant falls asleep, system can notify the occupant in building effectively, because acoustical generator is contained in the outside in room.
U.S. Patent No. 5,587,705 solve these problems, and its way provides a kind of smoke-detectors, it is directly got in touch and operates with other smoke-detectors of same design with other smoke-detectors by making alarm, and the terrible disaster in the middle of need not monitors panel.In this patent, communicate by letter by moving behind the detecting device that detects smog.Detecting device sends the chimes of doom of oneself, and with the radio signal of a certain frequency send to be tuned to other contiguous detecting device of this frequency.The detecting device that receives this radio signal sends the pulsed chimes of doom, to living away from the building that starts smoke-detectors as a kind of early warning system.Though this system has realized the control of not concentrating still lacking dirigibility, especially because only at the interior detecting device of radio reception distance sounding simultaneously, also because of these detecting devices can only with other compatible communication detector.After a bit mean and will spend sizable expense that this class detecting device is installed in the building could constitute a kind of efficient system because all detecting devices are necessary for same type.
Use the warning device that interconnects in the public domain and another problem that produces, being often to be difficult to identification is which device has sent alerting signal at first.This problem also state with certain noise alarm of identification is relevant, and this alarm is excessively responsive, sends false alarm easily.
The problem that also has that numerous smoke alarm unit users run into is that the state of reserve battery was not really clear during each installed.In the past, when battery level was lower than threshold level, smoke alarm unit utilized acoustical generator to produce a warning chirp usually.Yet this itself just has a problem, if at the same area some warning devices are housed, nonrecognition is which device is sending chirp.For the people of hearing difference, heard by them because chirp is difficult, so this problem is even more serious.
Therefore, the communication capacity that an object of the present invention is to provide a kind of and other device warning device more flexibly.
Another object of the present invention is at least one problem of alleviating prior art.

Describe in detail
Referring now to Fig. 1, shown in the figure according to the smoke alarm schematic representation of apparatus of a preferred embodiment of the present invention.
Primary power enters power supply changeover device 5 at active end 6 with neutral end 3, and the latter is transformed into about 10 volts with primary power on the power rail 15 that is used for the warning device power supply.Green light LED 17 is connected to power supply changeover device 5, and is luminous when described converter operate as normal, shows the ac main power on visual type, and the smog alarm apparatus works.This device comprises the disposable reserve battery 7 of the anode that is connected to battery monitor module 13 and diode 11.The negative electrode of diode 11 is connected to the output terminal of power supply changeover device 5.By reserve battery 7 is connected to power rail 15 through diode 11, battery provides the electric power support when primary power or power supply changeover device 5 faults.
Battery monitor module 13 also is connected to yellow light LED 19, is lower than threshold level if the voltage of battery 7 drops to, and battery monitor module 13 is just lighted LED19.Therefore, by the warning device that makes the yellow light LED point look or glimmer and lost efficacy with the visual identification reserve battery, overcome with the low and relevant chaotic situation of " chirp " expression reserve battery level, this characteristic may be particularly conducive to ionization type and the photoelectric type smoke alarm that adopts interchangeable or rechargeable battery.In addition, visual indication can be used as the uniqueness indication of battery level or uses with " warbling " indication that can listen.
This warning device also comprises a digital logic chip 21 that monitors detector module 23.Preferably a kind of smog of this detecting device or fire detector, but can be to be used for detecting such as other status detection devices such as specific gas or translation motions equally.At detecting device is among the embodiment of a kind of smog or fire detector, is detecting smog or adstante febre, and detector module 23 is just sent signal.Press test button 29 order test generators 30 and send emulation Smoke Detection signal to logic chip 21, can the working condition of analog detector module 23 when detecting smog.
The work of smoke-detectors unit in the key diagram 1 now.In case detect the Smoke Detection signal from Smoke Detection module 23, logic chip 21 just is set to specific logic level (as 9 volts of current potentials) with two-way detection I/O terminal 27 and the 4th terminal 4, with indication Smoke Detection signal and expression fire is arranged.So red-light LED 25 is locked high level, thereby even if after the Smoke Detection signal no longer takes place smoke-detectors module 23, its still not de-energisation.Latch can be the ingredient of warning LED control module 24, or can configuration logic chip 21.Logic chip 21 also drives hummer 31.
Hummer continues sounding, no longer detect smog up to signal indicating from smoke-detectors module 23, logic chip 21 de-energisation hummers 31 made detection I/O terminal 27 and the 4th terminal 4 return low level, and sent a negative acknowledge character (NAK) to warning LED control module 24 this moment.After the hummer de-energisation, red-light LED 25 keeps a little while bright, and dimness is gone down automatically then.Usually, LED25 secretly fell after about 5 minutes.
Detect the I/O terminal and be connected to other compatible warning device relevant detection I/O terminal.Therefore, when detecting smog, the detection I/O of Fig. 1 warning device is set to high level, notify the warning device of any one connection to detect fire, cause their alarm to drive, thereby the resident of building other parts is constituted the early warning warning.On the contrary, the smoke alarm of Fig. 1 can receive from another signal of warning device far away, and allows its warning sounding and as early stage alert warning device.These features will specially be described in a more detailed discussion with reference to Fig. 2.
The 4th terminal 4 is terminals except detecting the I/O terminal, and it is connected to the compatible apparatus of one or more outsides.Therefore, it can notify one or more external device (ED)s to detect smog, thereby allows them make corresponding response.For example, the 4th terminal can directly send signal to drive sprinkler system to the drinks fire extinguishing system.The 4th terminal also can receive signal from external device (ED) to drive this warning device as early warning.The 4th terminal 4 directly or indirectly and logic chip 21 join, Fig. 1 is indirect method of attachment.
If logic chip receives from the drive signal that detects I/O terminal 27 or the 4th terminal 4, it just drives hummer 31.At this moment, " early warning " hummer can be different from " driving detecting device " hummer, thereby the resident can determine that their warning is to drive to report to the police or the early warning warning with the sense of hearing in the building.
Fig. 2 further illustrates the working condition of a plurality of warning devices of 27 interconnection of I/O terminal after testing, and warning device A, B, C are identical with the warning device of Fig. 1, so the same label of use in describing.The detection I/O terminal of all three warning devices is connected together by cable 33.When the most close certain warning device for example installed the A breaking out of fire, the smoke-detectors module will detect relevant smog and produce detection signal in this device.Logic chip 21A will monitor and detect I/O terminal 27 among the device A, find its floating ground and be placed on high level, also latch ruddiness warning LED25A and drive hummer 31A.Detect I/O port 27A among the logic chip 21A and in a single day be set to high level, bi-directional logic port 21B, the 21C of logic chip will become high level by being connected to cable 33 respectively among warning device 13 and the C.In case the logic chip among device B and the C detects alarm condition at its two-way detection I/O terminal 27B, 27C, they will drive its hummer 31B, 31C respectively.
Then, the smoke-detectors module 23A in warning device A no longer is in this moment of Smoke Detection state, and logic chip 21A returns I/O terminal 27A to low level, thereby the two-way detection I/O terminal 27B and the 27C that connect also reduce to low level.Logic chip in all devices is also to its hummer de-energisation separately.Yet the warning LED25A of device among the A will keep shinny for example about 5 minutes, thereby show just this device first alerting signal that started to the observer.Like this, even after warning device all stops sounding, still can identify this easily and start alarm and need not complicated wiring.
Such indication helps EARLY RECOGNITION fire or alarm source, and the result has reduced the time and the relevant expense of searching cost.Can also allow whether resident's identification has driven alarm in their room in the building, and if in the room in alarm be not driven, then reporting to the police occurs in the distant place.This warning diagnostic characteristic can be provided and be need not extra hardware by smog alarm apparatus of the present invention, and the result has saved equipment and labour cost.
In another embodiment, thereby detect smog and install logic chip among B and the C at I/O terminal 27B, when 27C detection alarm state drives its hummer as device A, their warning LED25B, 25C also can be driven, but do not latch.Therefore, when the signal of I/O terminal drops to low level,,, only allow the warning LED25A of device A keep shinny preset time, so that show the device of this alerting signal that starts simultaneously to warning LED25B, 25C de-energisation to the hummer de-energisation.
In Fig. 3 and 4, all smog alarm apparatuses are expressed as in the warning system that is integrated in the building.At this moment by " the 4th terminal " (representing with label 43A, 43B, 43C on each device of Fig. 3) being set and these terminals being connected to directly or indirectly a certain external device (ED) realizes.An example that is connected to external device (ED) indirectly is by a warning monitor board.Fig. 3 and 4 illustrates this layout.
Referring now to Fig. 3, illustrated structure has smog alarm apparatus D, E, the F of three or similar type same with Fig. 1, also has a warning monitor board 41, and it utilizes three often opens (disconnecting when promptly going to energize) relay 45,46,47 is with each alarming device interface.According to the present invention, warning device D, E, F can drive with warning monitor board 41 easily.This ability is provided with the outside and can contacts in each warning device+and 9 volts of " the 4th " terminal 43D, 43E, 43F realize.
Externally install and utilize when for example its one or more wiring 49 are with disaster intelligent surveillance plate 41, it can determine to drive warning device D, E, F.Driving these warning devices allows electric current pass through relay 45,46,47 realizations.This electric current is energized and Closing Switch 50,51,52 to the relay coil in the relay 45,46,47, is connected to their " the 4th " terminal 4D, 4E, 4F separately thereby will detect I/O terminal 27A, 27B, 27C.Therefore, each warning device D, E, F will enter alarm condition.Be noted that as in the preferred embodiment warning device does not latch their warning LED25D, 25E, 25F, latch and only occur in the warning device that starts, and in the present circumstance, alerting signal does not start in any warning device.
Should point out that in Fig. 3 embodiment, All Alerts device D, E, F are in parallel with warning monitor board 41, all warning devices do not interconnect (the I/O detection terminal that is each warning device does not directly connect mutually).Therefore, this represents that all warning devices work alone as smoke alarm, if drive signal is sent through the 4th terminal 4D, 4E, 4F by the warning monitor board, just can drive simultaneously.But point out, though each warning device D, E, F can not be as the early warning system mutual driving alarm, but they can both send signal to warning monitor board 41 respectively through relay 45,46,47, notify this panel that fire is arranged, panel can drive such as the external device (ED) of sprinkler system one class or additional outside strobotron or siren thus.
Referring now to Fig. 4, illustrated another kind of structure has identical with Fig. 1 device with three or the similar warning device G of a monitor board 41, H, J.Utilize this structure, connect a warning device (G) with 55 on a relay.Common conductor 33 interconnection detect I/O terminal 27G, 27H, 27J.When monitor board 41 determines that the smog alarm state exists, it is energized to the coil of relay 55, Closing Switch 57 and all energize to detecting I/O terminal 27G and the 4th terminal 4G thus, logic chip 21G identifies alarm condition and drives hummer 31G as a result, and drives warning LED25G selectively.Detection I/O terminal 27H, 27J have been connected to cable 33 owing to detect I/O terminal 27G, so warning device H and J enter alarm condition equally.Though each warning device all can illuminate its warning LED, warning device does not latch their LED, and reason is that alarm command starts by monitor board 41 rather than by any warning device G, H, J.
Be noted that the difference between Fig. 4 and Fig. 3 embodiment is what all warning devices interconnected in this example, therefore in this embodiment, if warning device G detects smog, it has just driven the detecting device H and the J of other interconnection.
Therefore, studied all these exemplify with embodiment after just understood that I/O detection terminal and the 4th terminal make each smoke alarm strengthen dirigibility in that suitable configuration aspects is set mutually.
The invention is not restricted to arbitrary particular form, should be understood that the details of the foregoing description can be done to change to satisfy different requirements.For example, the 4th terminal of warning device needn't be connected to external device (ED) with rigid line through relay, for example can realize connecting through dedicated radio link.Unique requirement is that the 4th terminal can be got in touch with one or more external device (ED)s.
In addition, other warning device layout can be arranged, comprise other structure that is equipped with the warning monitor board or directly is connected to one or more external device (ED)s.
