Embodiment
Fire detection system shown in Fig. 1 schematically shows center 1 and the various different alarm circuits that are connected with center 1, alarm circuit M
1Manual alarm devices 2 is arranged, alarm circuit M
2Special alarm is arranged, shown in going up according to figure with fire alarm 3 and circuit extension alarm device 4, alarm circuit M
3So-called point type alarm 5 (the parasitic light smoke alarm that is installed on the roof is arranged, temperature alarm, flammable gas alarm or many standards alarm), it is to be connected with center 1 by independent alarm circuit that operating means 6. these figure that also expressed the variant alarm of local operation do not should be understood to every type of alarm; In contrast, various dissimilar alarms can be connected with a common alarm circuit in all cases. suitable spuious circuit smoke alarm, for example, in EP-A-0 636 266 and EP-A-0 821330, be illustrated, in european patent application No.01 114 103.3, circuit extinguished alarm and in EP-A-0 718 814, fire alarm also is illustrated.
Term operating means 6 should be done wide in range understanding. and it can be as an assembly that is used for carrying out with alarm the telechiric device of data communication, or being used for changing/inserting or check a kind of instrument of the alarm that can be used for data communication simultaneously. operating means 6 shown in Figure 1 is a kind of type tool in back, it comprises so-called alarm tester and/or alarm extracting device (hereinafter referred to as test extracting device 7), it be used for checking function and/or be used for alarm insert base and/instrument that takes out from base, and be used to import and the terminal 8. of video data
Half shows the communication interface of alarm 5 to Fig. 2 on the left side, KM represents with reference marks, and the right side half show the communication interface of test/leading-out end 9, KB represents with reference marks, these two halves are separated from each other it with the dotted line A of symbol transmission medium. and these two communication interface KM and KB have optics and electro-induction separately respectively, channel KMo, KMi and KBo, KBi. the optical channel KM. of alarm communication interface KM comprise one outside can observable warning indicator 11, it is made up of the LED that is used to report to the police with the indication of fault optics, and the optical channel KB. of 13. tests of led driver that is connected with the microprocessor 12 of alarm and leading-out end communication interface KB comprises light emitting diode 14, the amplifier 15 that is connected with light emitting diode, and pulse shaper 16, pulse shaper is connected on the back of amplifier, and its output is connected to the microprocessor 17 of operating means.
The electro-induction channel KBi of test/leading-out end communication interface KB comprises by the oscillator 18 of microprocessor 17 control with by for example, the electro-induction channel KMi of the inductance 19. alarm communication interface KM that coil constitutes comprises resonant circuit 20, after be connected to the detuner 21 of resonant circuit, and pulse shaper 22, pulse shaper is connected with detuner, its output is connected to microprocessor 12. coils 19 and inserts in the test/leading-out end 9 that is pulled on the alarm 5, test/leading-out end 9 is pushed on the alarm that contains resonant circuit 20 at each transmission course. and light emitting diode 14 is arranged in test/leading-out end 9, the effect of light that makes warning indicator 11 emissions is on it. for example, just can realize this point by mechanical coding, this mechanical coding only just allows test/leading-out end 9 to be pulled on the alarm 5 at single relative position. certainly, also can select coding like this, make a plurality of relative positions become possibility. in addition, the communication interface that is used for high-frequency range communication preferably designs according to bluetooth standard or is used for preferably designing according to the IrDA standard of infra-red range.
In principle, terminal 8 can be fixed on pipe 10 or the extension, and be designed so that operating personnel can be in hand-held test/leading-out end 9 of waiting to operate on the alarm 5, energy operating terminal 8, but more than the certain space height, the strength that costs a lot of money just can be accomplished this point. for this reason, for example the terminal 8 that is made of hand-held device or PDA (personal digital servicing unit) is not mounted on tester/extracting device 7, but it is taken off from tester/extracting device 7, and for example communication link wiring according to IrDA standard or bluetooth standard is arranged between terminal 8 and the test/leading-out end 9.
For the data that begin from alarm 5 to test extracting device 7 transmit, to test/leading-out end 9 passes alarm 5 and location thereon. and the requirement according to component communication interface KB is set in data transfer mode with alarm again. and data are sent to test extracting device 7 and are stored in the there from alarm 5, indicating into simultaneously thick information (mistake/but) also can read said information from 7m distance far away. and will test extracting device 7 then and take off from alarm 5, this information if desired can be retrieved the detailed content of institute's deposit data by terminal 8.
5 data transmit and carry out with analog form from terminal 8 to alarm, also carry out buffer memory in test extracting device 7.It also is possible that bi-directional data transmits. certainly, in a single day data enter terminal 8 and just can be deposited in to test in the extracting device 7 and at variant alarm place and use repeatedly.
If test extracting device 7 is self to be proved or to be identified as the operating means that data transmit that is used for that is allowed, alarm also can be set in data transfer mode with oneself independently. can carry out said confirmation by special code or cryptographic methods. and this has just prevented that other or device without permission are not intended to or are set in wittingly data transfer mode to alarm.
In data transfer mode, on the one hand, alarm 5 is operating period, for example, the data that inspection is picked up and stored during the proximity sensing etc. send to terminal 8, and on the other hand, can send to alarm to data or order, such as with the instruction of maintenance job or relating to parameters. in data transfer mode, perhaps can carry out software upgrading.Disclosed extremely significant advantage with system of operating means 6 is, in the following manner, for example notify the center: maintenance job is just carried out at alarm, or want centering that alarm is converted to appropriate mode, maybe will follow the data of transmission to write alarm, just can also use data transfer mode through this alarm in two-way connection of formation between operating means 6 and the center 1.
From operating means through the center to the indirect transmission of the data of alarm or order for same possible direct transmission, its advantage is, one side along be notified to the center with being with, also finished the change of carrying out in the alarm filtering function on the other hand and can have been stoped the change of not sending to this alarm.
Especially, by the relevant room number of operating means input and this number when the alarm center of being transferred to is equipped with the fire alarm system of a plurality of alarms, can carry out that two-way communication may be extremely helpful between center and the operating means, here, room number be associated with the alarm identification number again (this being seen also EP-A-0 546 401), thereby also alarm having been carried out clearly location. by alarm designs being become the node that communicates to connect between operating means and the center, can be connected operating means with the center through this danger detector as a portable terminal.This has just opened up transmit from alarm to center functional may.
Owing to each place that alarm is installed in buildings can be operated system, so debugging and required time of maintenance job have just reduced. in addition, needn't use form (choosing the danger of wrong item in the form or defective form) to select but directly specify on the spot owing to wait to be set at the alarm of other pattern, so can avoid operating mistake.
As obviously finding out from Fig. 1, fire detection system not only comprises usually and is installed on the roof and originally has been provided with the point type alarm 5 that is used for the operational testing extracting device, but also comprise special alarm, for example, such as manual alarm devices 2, fire alarm 3 and circuit extinguish alarm 4, though their big city are installed on the wall. do not use specialist tools to come attaching/detaching or said alarm is carried out the alarm test, but yet must carry out regular test on the spot to these alarms, in this case, before and after the test relevant alarm is carried out/ tests, thereby all situations that must be set in test pattern or normal operating state also must enter the center here.
In system according to the present invention, operating means 6 is designed so that it also can be used for operating said special alarm and other assemblies. Fig. 3 shows this multifunctionality that operating means 6 is associated with manual alarm devices 2, Fig. 4 then shows circuit is extinguished alarm 4, this multifunctionality that audible alarm unit 23 and so-called circuit pack 24 are associated. circuit pack is, for example, the I/O assembly, it is used for the fire-alarm of other patterns is connected to existing system or is used to connect face contact or rest(ing) contact, or be used for technique device such as fire-proof door, ventilating system, the dispersion starting of air-conditioning system etc.Other circuit pack is so-called line pad, even it is responsible for occurring on the alarm bus under the situation of short circuit, whole bus does not break down and has only the faulty component of circuit to be isolated out. and said circuit pack is generally flat boxlike shape and usually is close to each other and piles up setting, so to entering from the external world certain restriction is just arranged.
Concerning manual alarm devices 2, can use this operating means and not be used as great change. manual alarm devices as is known, is installed in about 150cm eminence on the wall, it is shaped as near square flat boxes, and the diagonal line of box approximates the diameter of point type alarm 5.Therefore, can flatly hold test extracting device 7 and place it on the manual alarm devices 2. because the extension of pipe 10 is not to be necessary, so terminal 8 usefulness, for example, it is favourable that spring clamp can be fixed on the pipe 10 expediently. test/leading-out end 9 is equipped with the component communication interface KB of pattern shown in Figure 2, alarm communication interface KM. is installed manual alarm devices because test extracting device 7 uses very easy operating of short tube 10, so needn't finish data communication in two steps.In this configuration, wireless communication distance is bigger than the distance under the point type alarm situation. by test extracting device 7 (limit switch) this situation is discerned, so improved transmitted power and receiving sensitivity.
Circuit shown in Fig. 4 extinguishes the shell that alarm 4 has metallic shield, thereby often be not suitable for the communication interface of pattern shown in Figure 2. to also being like this because of being the circuit pack 24 that stack arrangement can only use in narrow side, so, under the situation of the communication interface of using Fig. 2, so perhaps, can not determine operating means 6 with pile up in that circuit pack communicate. audible alarm unit 23 is the round box shape formula, the base that has projection, thereby alarm communication interface KM (Fig. 2) can be installed. test extracting device 7 and circuit extinguish between the alarm 4 and with circuit pack 24 between communicate by letter and undertaken by connectorized cable 25, making it can insert the circuit pack 24. that is arranged in piling up easily described plug design one-tenth extinguishes under the situation of alarm at circuit, the test extracting device also is used as mounting auxiliary, because catoptrics quality of signals and distance all show with online mode, thereby have simplified the adjustment of shell.
In the embodiment of the embodiment of Fig. 3 and Fig. 4, terminal 8 all is to carry out in the mode identical with Fig. 1 by IrDA interface or bluetooth with the communication of testing between the extracting device 7. certainly, under the situation of Fig. 3 and Fig. 4, terminal 8 also can be connected with test extracting device 7 by wired mode, but in these cases, uncurrent specific purpose tool must be arranged.Shown in solution advantage on the one hand be that operating means 6 provides the single instrument of operating various different alarms and assembly for installation personnel, use this single instrument, installation personnel not only can be operated these alarms, and can communicate by them and center.Advantage on the other hand is to have used standard interface (IrDA or bluetooth), replaces so operating means can be easy to be sold equipment by the merchant of prior art.
