Fig. 1 represents to be contained in the distribution arrangement of simplifying in the conventional fire alarm system of buildings or similar structures.A lot of responsors 10 are distributed in the buildings, and every layer several, and are connected on the master control borad 11 that is positioned at one deck or underground service area.This master control borad is connected to outside monitor service by phone usually.Each responsor is linked a plurality of manual calling points or other equipment, and as smoke detector, these are not drawn in the drawings.MCP is a mount type box on the well-known little wall, and each has glass cover, button or switch activator.Usually responsor by parallel low pressure (as 12 or 24V) line 12 is from the interchange or the DC power supply of mainboard 11, and communicate by letter with mainboard by bus 13.
An a lot of loudspeaker, the alarm 14 of sounder or flashlamp type also is distributed in the buildings, and near MCP.Generally, each alarm is similar to responsor, but also can be independent of main board power supply with the low-voltage alternating-current or the DC power supply of line 15 from the master control borad 11.After applying power supply, sounder just has a predetermined output, and in some cases, requires and the mainboard independent communication.The general requirement of loudspeaker in other system or relevant device has the communication bus (not shown) to receive corresponding audio frequency or other sophisticated signals.The triggering of this warning system can be arrived each responsor 10 through mainboard 11 by input or the smoke detector from MCP, or local to the mainboard (not shown) by connecting from other.If this system is in running order, each alarm 14 produces other outputs in desired audio frequency output or the other system.Should understand that responsor may always not have, still, for example, this system only can trigger from mainboard.
Fig. 2 represents is distribution arrangement according to fire alarm system of the present invention, wherein, the operation of each alarm 14 is subjected to the supervision of an event recorder 20, and each alarm is also powered from mainboard 11 by line 15, wherein for clarity, omitted the responsor or the relevant device that generally will provide.Each event recorder monitors the physics output of corresponding alarm, as sound or light intensity, and/or monitors the curtage of supplying with alarm, or various combination of going up parameter.This event recorder is usually by internal electric source such as lithium battery power supply, but also can be by line 15 from main board power supply.In test process,, provide of the indication of this equipment by desired operation to the supervision of alarm output.And provide other or interchangeable indication to the supervision of electric current, and promptly no matter whether it turns round satisfactorily, and this alarm reality is triggered.This event recorder can show the result of monitoring process usually in some way visually, typically by light-emitting component such as LED, or by following transmission one signal to central control board.
Make that at each alarm 14 place's Installation Events register 20 fire alarm system can be by single test, he can trigger this system simply, checks each register in the buildings then successively.Whether this register can temporarily or be pressed desired during the visit at least, indicate this trigger event to occur on the corresponding alarm.Can implement in the uncertain time, to trigger this system to the satisfied test that moves of alarm always, and this triggering is that mutually the people in the buildings is irritated in season, and also needn't rely on the situation that several observers checked and reported corresponding alarm simultaneously.Can be installed to existing system to a series of register in every way, or install when system just sets up at first, they can be the succinct and suitable cheap equipment that can cause minimum inconvenience when mounted, and power is little.The operation of each register also need detect, and can use mobile device to carry out relevant detection, and this mobile device is to alarm and event recorder power supply, and is as described below.
Fig. 3 a is the circuit diagram according to preferred event recorder of the present invention.This register is exported to physics from being monitored Equipment Inspection, and generates the visual indication that is used to observe, and promptly whether this equipment moves normally.In this case, this equipment is a sounder in fire alarm system, and physics output is the sound more than or equal to predetermined loudness.When triggering sounder to monitor the whether triggering effectively time the and when closing of this triggerings, the power supply of this register use sounder.After the power supply of sounder provides and reaches gratifying sound equipment value, just light a corresponding display lamp, and eliminate when sounder and also will keep one period schedule time after triggering, be typically half an hour to one hour or more.The power supply of this display lamp is provided by the long-life batteries that is included in the lighting circuit.This display lamp must keep the bright state sufficient time so that the people of inspection record device visits and check the performance of this lamp with the assessment sounder.If sounder power supply or sounder work are undesired or event recorder lost efficacy, this lamp just can not be bright.
By signal connector T2+vi in terminals from mainboard provide positive supply to register and by T2+ve out terminals are delivered to sounder.One adjust diode D1 be connected to T2+ve in and+ve out between, for the purpose of localized Performance Evaluation, offer register and sounder with the disjunct diode D1 of test connector T1, to separate with motherboard power supply.Test connector T1 contain an electrode wherein link T1+switch of ve end, T2+negative electrode of ve out terminals and D1.Second electrode of T1 switch linked T2's+anode of ve in terminals and D1.Normal condition T1 switch cuts out, unless the electric current that the plug in test connector is inserted into socket and disconnects D1 is adjusted function.At normal operation period, when register was connected, the T1 switch kept the mainboard wiring circuit to sounder.And D1 provides the backup battery circuit to sounder when switch failure.T1 and T2-ve end connected together each other, forms the negative terminals of mainboard, sounder and register jointly.
Signal connector T2+ve end test section on the incident of register circuit provides positive supply.Polarity protection diode D2, limit resistance R 1, voltage regulator diode D3 and filter capacitor C1, C2 form the event detector power supply and by by T1, T2+ve links to each other with-ve end.These device stabilized supply voltages also filter out the electrical noise in the event detection circuit and limit the power that register obtains from mainboard.
The microphone M1 that is used for detection of sound device output is by resistance R 2 power supplies, the electric current of this resistance limits microphone, and help the sensitivity of microphone by a part that forms the microphone load circuit.Diode D4, D5 and the capacitor C 3 of linking the microphone two ends provide nonlinear load on microphone, and reduce the signal output of microphone when sounder loudness increases above event detection loudness threshold value.This just increases the sonority scope that the amplifier of microphone by means of Q1, C4, R3, R4, C5 and R5 can amplify.The sound that receives by microphone causes variable voltage between the microphone terminals, wherein capacitor C 4 is coupled on the amplifier transistor Q1.Capacitor C 4 is also separated this amplifier with the microphone DC source.Resistance R 4 and R5 offer the amplifier output signal resistive load, and help to be provided with the voltage amplification of transistor Q1.Resistance R 4 is linked the register power supply and is provided power supply for transistor Q1, and with resistance R 3 dc state of amplifier is set.Resistance R 3, R4 are the main elements that links to each other with the feature of transistor Q1, and it is provided with the signal and the power supply characteristic of amplifier of microphone.The microphone signal that capacitor C 5 couplings are amplified arrives peak signal detecting element D6, R6 and C6, and they are separated from the amplifier DC circuit.
In cycle, diode D6 provides the forward current by capacitor C 6 at the microphone signal of being exported by transistor Q1 that is exaggerated.Utilize this electric current C6 storage electric weight to cause the DC voltage at C6 two ends to increase, negative half part in the microphone signal cycle end by the electric current of D6, and the part electric weight flows out capacitor C 6 by discharge resistance R6.The value that C6 and R6 are set is so that the peak value of the microphone signal that the DC voltage reaction at C6 two ends is exaggerated.The crest voltage at capacitor C 6 two ends is monitored by the pin 4 of voltage comparator ic 1.This voltage IC compares with the event detection reference voltage Vref 1 on the pin 3.When the voltage at C6 two ends was lower than Vref1, the output of the pin one of IC1 was general identical with battery B1 voltage; And when the C6 both end voltage was higher than Vref1, the output of the pin one of IC1 was roughly 0 or low level.The conversion of IC1 output pin 1 from the cell voltage to ground is used as the effective excitation trigger of incident by C7, R7, R15 and Q2, and voltage comparator ic 1 is powered continuously by long-life batteries B1.
When battery B1 links IC1 first, give capacitor C 7 initial charges by resistance R 7 and transistor Q2.In case C7 is full of electricity, electric current just ends to flow through R7 and Q2.Transistor Q2 works as linking the switch at capacitor C 8 two ends.When real estate was made trouble the part trigger pip, the electric weight that is stored among the C7 was just discharged by D7, R7 and R8 by IC1 conversion pin one.When the loudness of sounder remains on effective excitation threshold when above, IC1 keeps pin one be, and C7 discharges always.When sounder loudness was lower than effective excitation threshold, the IC1 pin one was withdrawn into cell voltage to capacitor C 7 voltages again.This just causes C7 to recharge by R7 and Q2.Electric current by Q2 makes transistor turns, so cause effective exciter lamp timing capacitor C8 discharge.In case C7 is recharged, charging current just ends to flow through Q2, so turn-off transistor.So this transistor is remained on off state by resistance R 8.
When transistor Q2 was turned off, lamp timing capacitor C8 charged up to voltage near battery B1 by resistance R 10 and R9.The value of C8, R9 and R10 is set so that C8 is full of the time of electricity fully enough to allowing the people of inspection record device visit and check the performance of lamp with the assessment sounder.The voltage at C8 two ends is monitored by the pin 6 of voltage comparator ic 1.Reference voltage Vref 2 on the pin 5 of this voltage and IC1 is compared.When the C8 both end voltage was lower than Vref2, IC1 was provided with the ground that outputs on the pin 8, caused that flow through resistance R 11 and lamp D8 of electric current causes that this lamp lights.When the build-up of voltage at C8 two ends to greater than Vref2 the time, the output that IC1 is provided with its pin 8 rises to the cell voltage of about B1, this just causes the electric current of flowing through lamps diode D8 to be ended and lamp extinguishes.Flow through what of electric current of this lamp of resistance R 11 decision, it is set to protect the certain value of battery life to guarantee certain lamp brightness simultaneously again.Wire jumper J2 can remove from the default position at resistance R 9 two ends, to prolong the demonstration time of lamp by the charging current that reduces capacitor C 8.The life-span that the lighting hours of prolongation lamp also will reduce battery.
2 reference voltages that provided by diode D9, D10, D11 and resistance R 12 are provided voltage comparator.The electric current that passes through these diodes and resistance is set so that from the element link, obtain suitable reference voltage.Wire jumper J3 at diode D10 two ends also can remove to increase minimum sonority value, and this value is stored as effective sounder excitation.
Fig. 3 b is the circuit diagram according to another event recorder of the present invention.This register detects load current and the physics output that is being monitored equipment, though the record of arbitrary parameter is normally gratifying.In this case, this equipment is a sounder in fire alarm system, and its physics output is the sound with a predetermined loudness and tone.When sounder was triggered, register stored the energy from power supply, and can indicate thus whether this triggering is effective.When gratifying electric current, sound and/or light output valve reach, just light corresponding display lamp, and after eliminating, keep bright state depleted always up to the power supply energy that is stored to the triggering of sounder.The people of inspection record device enough electric weight must be stored so that can visit and check the performance of lamp with the assessment sounder.Also can provide internal electric source.Just close lamp up to the register that the people comes and manual control can be lighted the lamp that uses storage power.If the sounder cisco unity malfunction, lamp just can not lighted so.
The forward power supply by terminals T2 and adjustment diode D1, was provided to register from mainboard before passing to sounder by terminals T1.Fuse F1 links to each other with voltage regulator VR1 with current-limiting resistance R0.Its scalable power supply is to 12V, and the forward power supply point S of a 11.5V is provided by diode D2.Electric current from this point flows to microphone circuit by resistance R 1, arrives capacitance stores and operation amplifier circuit by diode D5, or arrives the operational amplifier reference circuit by desired by resistance R 2.Operation amplifier circuit comprises the amplifier A1 and the A2 of standby current and sound equipment value.According to the present invention, any one or can use in the event recorder all.These circuit are similar and work is concise and to the point below describes.Certainly, for the operation of in other electrographs, using with adopt also and should illustrate separately.The microphone M1 that is used for the output of detection of sound device is by sensitivity control P1 and current-limiting resistance R1 power supply.The sound that is received by microphone causes changing impedance, and produces an alternating voltage.One direct current voltage is adjusted capacitor C 1, be used for negative back resistance R3 and the rectification diode D3 that moves towards electric current and produce DC current, smoothing capacity C4 and bleeder resistance R4 delivered current are by adjusting diode D4 and resistance R 7 with the positive input terminal formation voltage in operational amplifier A 2.By P1 and R7 Control current amplitude proper level at this operational amplifier.If the forward input voltage is greater than the negative sense input voltage, operational amplifier will generate the forward output voltage and electric current flows to illuminating lamp L2 from source I2.Resistance R 10 and R11 decision will be described below by the electric current of this lamp and the minimum holding current that passes through terminals T6 and T7.Electric current from illuminating lamp also keeps this lamp by the positive input terminal of operational amplifier always.
Load current by sounder also flows through register by terminals T3, T4 and resistor network R12, R13.Whether provide the power supply of 12V or 24V according to mainboard, terminals T3 can link to each other with T4 and also can not connect.When sounder was triggered, nearly 0.5V appeared at T3, T4 two ends, and wherein register is protected by fuse F2, and provided sensitivity adjusting by pot P2.Electric current flows through diode D6 and resistance R 6, at operational amplifier A 1 positive input terminal formation voltage.When this voltage when imposing on the voltage of negative input end, this amplifier will produce a forward output voltage and subsequently power supply flow to L1 to light this lamp from source I1.Resistance R 8 and R9 decision will explain below that by the electric current and the minimum holding current of this lamp the current flowing resistance R6 that comes from this lamp of lighting also keeps always.
After triggering this sounder from mainboard, register is started working.Capacitor C 2, C3 are connected keeping a suitable voltage rating, and use the electric current by resistance R 5 restrictions to charge.They operate with the register that is used for subsequently at storing electricity.For making operational amplifier that enough voltage be arranged and can lighting lamp L1 and L2, need there be the minimum several seconds duration of charging to guarantee the electric weight abundance.Diode D4, D5, D6 guarantee: electric capacity is only powered to operation amplifier circuit when the power supply of sounder and register is removed.Having the amplifier (as MAX332) that low electrostatic current requires should guarantee: after power supply removed, these lamps will keep bright sufficiently long time of state, a few minutes at least.
When the satisfactory operation of sounder, lamp L1, L2 should be lighted immediately, and can be configured to utilize capacitor C 2, C3 when sounder is switched off, or keep the electric weight of storage to arrive register up to the observer.If terminals T6, T7 are connected or T8, T9 are connected, then have electric current to flow out respectively from source I1, I2, and last till C2 always, C3 discharges into its voltage to be lower than operational amplifier desired.These general former need 30 minutes in circuit as shown in the figure.But can expect that the observer can not come before the depleted and lamp of storage power is closed.If one or another one or two butt joint line ends all not have to link to each other, then corresponding lamp current is almost just having when the observer pushes button PB1.Electric capacity slowly discharge approximately needs one hour, and this in whole fire alarm system, checks that for the observer each sounder and register are enough in test process.
What Fig. 3 C represented is to make event recorder monitor the optional rectification module circuit of this equipment.It also can make electric weight be stored in the register and needn't operate specialized equipment.This helps to reduce in test process the length that requires to have the equipment that makes one nervous such as alarm must move the time of being consumed.This module is linked the terminals T2 and the T4 of this equipment and register by power supply.
Fig. 4 is the square circuit diagram that can be used for checking the handheld meter of the event recorder operation shown in Fig. 3 a, 3b.This tester can insert at contact TP1, TP2, TP3 place or connect to advance register, and these contacts all illustrate in two figure.In case put well, it just can or pass through wireless signal receiver 41 and output 42 straighforward operations by button control 40 or manual operation.Selector switch 43 is used to select the desired procedure pattern with the switch that links to each other.By interface 49, and select corresponding setting just can implement various tests on the selector switch of explaining below 44.Power to tester by battery supply.And provide voltage and current to register, alarm or other with the equipment that the register of installing monitors by selector switch 48.When battery need charge, charger 46 was linked primary power by terminals 47 with the interlock switch that links to each other.
When testing first, by TP1 and TP2 apply supply voltage to event recorder to check relevant operational amplifier A 1 circuit and to be monitored the operation of equipment.If reach desired electric current of this equipment and sound level, just trigger this equipment and light lamp L1, L2 on the register.After supply voltage removed, this lamp also will keep a period of time, to carry out aforesaid observation.Supply voltage and electric current can check by voltage/current meter 50, this voltage/current meter can with the performance test that is used from this equipment near sound level reading one.Use when testing for the second time calibration sound source 51 and transmitter 52 with check microphone M1 and with the operation of operational amplifier A 2 interlock circuits.Forbid getting the sound that produces by tester so that microphone is only lifted from the output that is monitored equipment.
The adjustment diode D1 of register also can test with forward direction or inverse current.At first shown in Fig. 3 a, apply a forward current.This electric current flows through shunt and flows back to by the interlocking contact on the tester.If diode operation is normal under forward direction, lamp will be lighted and display voltage and electric current on tester 50.Apply negative current then to determine that at reverse diode down be to be open-circuit normally or at least.Corresponding lamp is lighted and display voltage and current value again.
Fig. 5 indication be a fire alarm system, wherein register 20 itself is installed together with this system rather than in other places.Three event recorders wherein two be segment set member as their corresponding alarm 14, and another one is independently installed.These registers can the directly operation test of their corresponding alarm 14 of indication on mainboard 11.By line 50 to corresponding that described with reference to Fig. 1, can reach this purpose with the responsor 10 that mainboard communicates.In each case, transmit on the simple numerical signal online 50.Event recorder also can directly be communicated by letter with mainboard 51.To any mode, the information of moving about each alarm passes on the graphics device 51 of mainboard thus.Because the power supply by capacitor C 2, C3 storage may not need, and therefore can revise the circuit of Fig. 3 b in this system yet.
This invention makes the accident early warning system meet safety requirements and suggestion.It makes that the warning system as fire alarm system can often be tested and the unlikely occupant who causes tedious noise multi-story office or unit, apartment.A plurality of improvement of the present invention can be arranged in the scope of following claim.
