Definitions

  • the invention relates to a method for automatically querying the detector measured value and / or the detector detection in a hazard alarm system according to the preamble of claim 1 and a device for performing this method.
  • Hazard detection systems are often equipped with different types of detectors. As an example she mentions a fire alarm system to which smoke, heat, flame and push button detectors are connected. The measured physical fire parameter is evaluated in the detector using a suitable algorithm. Only a standardized, generally digital signal is transmitted to the control center. Different parameters are often evaluated in the detector using different algorithms. Alarm systems are also known which no longer evaluate the fire parameter in the detector, but instead pass it analogously to the alarm center in a suitable transmission method, in which an evaluation device, preferably a microcomputer, processes the measured values of all the detectors. Such alarm systems are also used for intrusion protection.
  • Such a signaling system is described for example in DE-PS 25 33 330.
  • the detector is prompted to emit a current pulse with a pulse duration proportional to its measured value.
  • the address of the individual detector and the analog detector measurement value are determined by measuring the lead time using an evaluation device.
  • DE-PS 25 33 382 a method is described for such alarm systems, which electrically separates all detectors from the detection line at the beginning of each query cycle and then switches the detectors on in a predetermined order in such a way that each detector after a time delay corresponding to its measured value additionally connects the following detector to the line voltage.
  • An evaluation device is located in the control center, which determines the respective detector address from the number of previous increases in the line current and the measured value from the length of the relevant switching delays. There, the analog detector measurement values are linked to obtain differentiated fault or alarm messages.
  • detectors that are triggered for test purposes, such as revision, must not cause an alarm. They should only show the response at the headquarters. In such cases, it is necessary to identify different types of detectors or operating states and to inform the control center.
  • a detector identification namely the type or status of the detector
  • Detector-specific identifiers can be saved in the control center for each detector in the system.
  • This entry of a detector identification which is generally carried out manually, is correspondingly stored via switches or a keyboard.
  • the data entered must exactly match the current status of the system. Errors caused during input or when replacing a detector can not be reliably detected by the system and can have serious consequences in the event of an alarm. If a change is made to such systems, e.g. if one detector type is exchanged for another, because the room is used for another purpose, this must also be entered in the control center.
  • a device for transmitting control commands in a fire protection system is known.
  • the individual detectors have timers as described in the above-mentioned patents. These are used for the transmission of control commands on the zone to the individual detectors, whereby the detector is only ready to receive during the running time of the timer, and only one timer can be switched on with the control devices provided in the detector within a control cycle on the zone, and the start time of the individual time elements can be evaluated in the central office as the address of the control element assigned to the relevant time element.
  • the control command received by the relevant detector is evaluated as a switching command for actuating a control member assigned to the detector.
  • the object of the invention is therefore to avoid manual entry of the detector identification in the control center and to specify a method and a device for automatically querying the detector identification and / or the detector measurement value.
  • a detector-specific identification is to be automatically detected and, if necessary, evaluated with the detector measured value in the control center.
  • the control commands are evaluated as changeover commands in the detector.
  • the timing element is switched from the transducer to the identifier, which sets the timing element to a characteristic time. For example, this time corresponds to the identifier for the detector type. Depending on the detector type, a corresponding detector detection is set. With the next polling cycle, the running time of the timer for the relevant detector is identified as its identifier, e.g. Detector type, evaluated.
  • This detector control is used to cause the detector to transfer its identifier.
  • the detector whose identifier is to be queried is therefore first activated.
  • a defined change in the detector measured value can be effected in the individual detector instead of switching to detector detection.
  • the generally microcomputer-controlled center can determine the detector detection and at the same time also calculate the original measured value. With this method, therefore, no detector measurement values are lost.
  • Another advantage is that not an absolute, but only a relative accuracy of the measuring device is required in the center.
  • the duration of the switchover to detector detection or for the duration of the defined influencing of the detector measured value as a function of the detector detection to be determined by a further timing element arranged in the detector.
  • This second timer is controlled by the switching command.
  • the duration of the switchover or the predetermined change in the measured value can be set for a query cycle or for several query cycles with this second timer. It can thus be the detector detection in several successive queries, which is for transmission security, and transmitted to the control center.
  • the object is achieved by the characterizing features of claim 4 and claim 6.
  • a switching device which can receive control commands according to the method described at the outset, a switching device, a further timing element and an identifier are additionally arranged for the method according to the invention.
  • the analog measured value reaches the first timing element from the transducer via the switching device, which is formed by a changeover switch.
  • the second timing element which is acted upon by the first timing element and a threshold switch via a coincidence element, switches the switchover to a second switching position, at the second input of which the detector identification from an adjustable identifier is present.
  • the changeover switch is thus arranged between the identifier, transducer and the first timing element and is switched over by the second timing element.
  • the control command or changeover command via a coincidence element only reaches the second timing element via the threshold switch when a signal is present at the second input of the coincidence element, which is acted upon by the first timing element.
  • each detector has a threshold switch for the targeted reception of the control commands, which is connected to a coincidence element. This receives a signal from its second input only during the duration of a first timing element, so that the coincidence element only issues a switching command pending on the signal line to a second timing element connected downstream of the coincidence element during this time. For the period of time determined with the second timer, this controls the switching device which is assigned to the identifier.
  • the identifier is connected in parallel to a transducer, so that the detector measured value is routed via the identifier to the input of the first timer. If the switching device is not activated, the unaffected detector measurement value reaches the first timer. If a certain detector has received a switching command, the detector measured value is changed by a defined value that can be set on the identifier due to the identifier.
  • a detector with identifier for switching to detector detection is shown in the schematic diagram.
  • the detector M is connected to the control center via an alarm line ML, which is not shown here.
  • the message line ML consists of conductors 1 and 2, between which a voltage U is applied.
  • the detector M essentially contains a timer T1, which is started when the voltage U is applied.
  • the running time of the timer T1 is influenced by the transducer MW.
  • the line voltage U is briefly switched off for synchronization.
  • the timing element T1 is triggered only when the voltage U is applied.
  • a capacitor C1 which supplies the transducer MW in the short time of the disconnection.
  • a diode D1 prevents feedback.
  • a threshold value switch SW is arranged in the detector M, which compares the voltage on the signal line ML via the voltage divider R1 / R2 with a predetermined threshold value sw. Changes in the time in which the timer T1 runs, the voltage on the signal line ML such that the threshold switch SW responds, this temporal coincidence of both signals is evaluated via the coincidence element KO as a control or changeover command. With the output signal of the coincidence element KO, a second timing element T2 is started for a predeterminable time.
  • the second timer T2 controls a changeover switch US.
  • This switch US is arranged between the transducer MW and the first timer T1.
  • the transducer MW is connected to the first input E1 of the switch US.
  • the output A of the switch US is connected to the input E of the first timer T1.
  • the identifier (R3 / R4) leads to the second input E2 of the switch US.
  • the identifier (R3 / R4) is formed by a voltage divider R3 / R4. In the exemplary embodiments according to FIGS. 1 to 3, it is connected to the conductors 1 and 2.
  • the center tap of the voltage divider R3 / R4 leads to the second input E2 of the switch US. Setting the detector type, a certain division ratio is set for the detector type in question, so that the voltage at input E2 of the US switch indicates the detector identification (e.g. the detector type).
  • This identifier will be transmitted to the control center instead of the measured value during the next polling cycle. Since the control is also carried out by the control center, the received signal is correctly interpreted as detector recognition and processed further.
  • the type of detector for the detector concerned is stored in a memory provided in the control center in order to be readable for the detector evaluation.
  • the changeover switch US is switched back to its initial position, i.e. the analog detector measured value signal reaches the first timer T1 again, so that the measured value can be transmitted to the control center again in the next query.
  • FIG. 2 shows a detector M in which the changeover switch US is formed by a relay REL with the changeover contacts E1, E2 and A.
  • the timing element T2 is formed by a monoflop MF which is acted upon by an RC element R T and C T.
  • the output of the monoflop MF controls the relay REL, which switches from position E1 to position E2, so that the voltage of the voltage divider R3 / R4 is present at the input E of the first timing element T1 for the next interrogation cycle.
  • FIG 3 shows a further exemplary embodiment of a detector M, in which the changeover switch US is formed by an analog changeover switch AS.
  • the timer T2 consists of a capacitor C2 and a resistor R5.
  • the capacitor C2 is slowly charged to the line voltage via the resistor R5. If a changeover command is received, the output of the coincidence element KO drives the transistor TR2, which becomes conductive and discharges the capacitor C2.
  • the voltage across the capacitor C2 controls the analog switch AS via the control input St. This means that if there is a low voltage at control input St of the analogue switch AS, the signal for detector detection goes from E2 to A, if there is a high voltage at control input St, a signal (measured low value) flows from E1 to A. Time for switching can be set with resistor R5 and capacitor C2.
  • Fig. 4 shows the circuit diagram of a detector M according to the invention, which is connected to the central alarm unit via a signal line ML.
  • the signal line ML consists of the conductors 1 and 2, between which the voltage U lies.
  • the detector essentially contains a first timer T1, which is started when the voltage is applied.
  • the running time T1 of the timing element is influenced by the transducer MW. Since the line voltage U is briefly switched off for synchronization at the beginning of a query cycle, a capacitor C1 is provided, which supplies the transducer with voltage during this time.
  • a diode D1 prevents feedback.
  • a threshold switch SW compares the voltage on the signal line ML via the voltage divider R1 / R2 with a predetermined threshold value sw. If the time in which the timer T1 is running changes the voltage on the line in such a way that the threshold value switch SW responds this temporal coincidence of both signals via the coincidence element KO as Control command evaluated.
  • This control command serves as a switching command for a defined change in the measured value.
  • the control command is carried out via a second timer T2, with which the duration of the measured value change can be set.
  • the second timer T2 is formed by a monoflop MF.
  • the monostable multivibrator MF is triggered with the output signal of the coincidence element KO and stores the control command at least for the duration of the query.
  • the storage time is determined by R T and C T.
  • the output Q of the monoflop MF controls the switching device SE.
  • This has a first transistor TR4, which becomes high-resistance and blocks the second transistor TR3 via the resistors R6 and R7.
  • the voltage divider with which the detector detection is set consisting of the resistors R3 and R4, becomes effective and reduces the output signal of the transducer MW in accordance with the divider ratio R3 / R4.
  • the detector detection is determined by the voltage divider R3 / R4. After the time determined by R T and C r , the monoflop MF drops. The transistors TR4 and TR3 become low-resistance, so that R3 is short-circuited. The voltage divider R3 / R4 is ineffective. The full output voltage of the transducer MW is again present at the input of the timing element T1.
  • FIG. 5 shows a circuit arrangement similar to FIG. 4.
  • an analog switch AS is used.
  • the monoflop MF there is a capacitor C2 and a resistor R5.
  • Capacitor C2 is slowly charged via resistor R5 to the voltage across capacitor C1.
  • the output of the coincidence element KO drives the transistor TR2. This becomes conductive and discharges the capacitor C2.
  • the voltage across the capacitor C2 controls the analog switch AS via the control input St.
  • a small voltage at the control input St causes the connection between I and A of the analog switch AS to become high-resistance.
  • the reduced detector value which contains the identifier, is transferred to the control center.
  • the connection from E to A of the analog switch AS is low-resistance, i.e. transistor TR2 is blocked and capacitor C2 is charged.
  • the duration of the timer T2 i.e. the storage time of the elements MF or R5 and C2 can be dimensioned such that the identifier is only passed to the head office once or in the case of several successive queries in order to identify possible transmission errors.
