Definitions

  • the invention relates to a wireless hazard detection system with a reporting center and at least one reporting device, the reporting center receiving and evaluating a radio message emitted by the reporting device in the event of a reporting event, and to a method for wireless hazard reporting, with a radio report when a reporting event occurs Event and then evaluated.
  • Such alarm systems and procedures are used, for example, to submit intrusion, fire, home automation or other malfunction reports or for emergency call signaling.
  • Previously common wireless hazard detection systems have technically very simple radio modules that can easily be influenced by interference fields, such as those caused by local oscillators, television sound carriers or computer clock signals and their harmonics.
  • the wired hazard alarm systems have therefore been given a delay compared to the wireless ones, although the wired systems have the disadvantage of high installation effort and thus little flexibility.
  • FIG. 5 shows a block diagram of such an alarm system with a message center 1 and various message devices such as sensors 2 (motion detectors, glass break sensors or door contact sensors), an emergency transmitter 5 and a radio lock transmitter 6, which automatically sends a radio signal to activate the alarm system when a door of the building to be secured is locked.
  • sensors 2 motion detectors, glass break sensors or door contact sensors
  • radio lock transmitter 6 which automatically sends a radio signal to activate the alarm system when a door of the building to be secured is locked.
  • Each signaling device that takes part in radio communication identifies itself with an individual code, a so-called unique code.
  • the alarm center 1 teaches in all existing alarm devices.
  • the transmission channel is permanently monitored by the alarm center 1 for malfunctions or tampering due to unauthorized access and the user is constantly informed about the effectiveness of the security by means of a display.
  • the sensor in question When a report-relevant event occurs, i.e. when a sensor is triggered, the sensor in question emits a short, coded radio signal, which is received by the signaling center and with regard to emitting an alarm via a signaling device 7 (flashing light and / or siren) and / or forwarding the alarm message via a public telephone network 4 is evaluated.
  • a signaling device 7 flashing light and / or siren
  • the alarm message is forwarded via the telephone network 4 via a telephone dialing device 3.
  • a block is displayed on the control panel 1 after a certain period of time, but does not trigger an alarm.
  • the alarm devices of the wireless hazard alarm system only send in the event of an alarm, i.e. only when they are triggered, a short radio signal with a maximum duration of 30 seconds, whereby a duration of approximately 1 second is usually selected.
  • the signaling devices are deactivated for a predetermined period of time after an alarm signal has been given and put into a so-called "sleep state".
  • the activated signaling sensors are put into sleep mode so that the burglar can switch off the jamming transmitter and pass through the deactivated signaling devices without triggering an alarm.
  • a signaling device according to the preamble of claim 1, characterized in that the radio message emitted by the signaling device consists of at least two radio signals of different frequencies.
  • the object is also achieved by a signaling center according to the preamble of claim 8, characterized in that the signaling center receives and evaluates at least two radio signals of different frequencies as radio messages.
  • the object is achieved by a method for wireless hazard reporting according to the preamble of patent claim 30, characterized by the steps of generating at least two radio signals of different frequencies as radio messages, transmitting both radio signals when the event relevant to the alarm occurs, and evaluating both radio signals with regard to a signaling requirement.
  • a blocking of the signal transmission from the signaling center 1 to the signaling device 7 can be prevented by a transmission device for the multi-frequency transmission of the signaling control signal, so that hard wiring is not necessary.
  • control center 1 can thus receive and evaluate at least one of the two radio signals and, if appropriate, trigger an alarm.
  • a deliberate blocking of both frequency channels by means of a jammer by a potential burglar with the aim of decommissioning the system can lead to an alarm immediately, since the probability of a simultaneous, accidental blocking of both frequencies can be almost completely ruled out. This makes it possible to differentiate between an intended fault and an unintentional one.
  • a signaling device characterized by a setting device by means of which a number of radio messages which can be reissued can be set until a deactivation period (sleeping time) occurs and / or the duration of the deactivation period.
  • the adjustability of the sleep time enables the signaling device to be adapted to the hazard potential of the area to be monitored, which means that the overall energy consumption can be minimized.
  • a wireless hazard alarm system according to the preamble of claim 21, characterized by a test transmitter which emits a radio test signal of at least one frequency when the signaling center detects an external signal, in order thereby to check the availability of the transmission channel.
  • test transmission device for automatically checking the transmission channel when a External signals enable the hazard detection system to be recognized immediately, regardless of the activation of a reporting device. This means that the system can be blocked even in the non-critical state and suitable countermeasures can be initiated.
  • FIG. 1 A block diagram of the wireless hazard warning system according to the invention in accordance with an embodiment is shown in FIG. 1.
  • the hazard detection system consists of a control center 1 with a receiving part 10 and a transmitting part 11, one or more motion detectors 21, contact detectors 20, smoke detectors 22 and temperature or water detectors 23 as detection devices, a hand transmitter 5, a remote control 8 and a lock transmitter 6 as Control devices of the hazard alarm system, as well as a universal receiver 710 for an optical and acoustic signaling device 71 and an optical and acoustic signaling device 70 with an integrated universal receiver.
  • the control center 1 is equipped with a test transmitter, which is used in connection with a remote test receiver or transponder 24 for checking.
  • the receiving part 10 of the signaling center 1 has two antennas 90 and 91 for two-frequency operation. Furthermore, a display panel 100 and a key switch 110 for activating (arming) or deactivating (disarming) the hazard alarm system are arranged on the front of the housing.
  • the receiving part 10 of the signaling center 1 is equipped with an internal tone generator with volume control and an acoustic signal transmitter, such as a piezo buzzer, arranged on a main circuit board.
  • the alarm devices send out an alarm signal, a third-party warning signal (sabotage signal) or a battery discharge warning signal on two different frequencies when a corresponding alarm-relevant event occurs.
  • frequencies from the following frequency range pairings can be used in dual-frequency operation, with one of the frequency values being used in a single-frequency operation that is also possible: Germany, Austria, Switzerland: 40/433 MHz Great Britain: 173/418 MHz France: 152/433 MHz
  • the radio message consists of more than two radio signals of different frequencies.
  • the transmitters of the signaling devices may only emit a radio signal for a maximum of 30 seconds. Therefore and for reasons of energy saving, the motion detectors 21 are put into a temporary deactivation state (sleep time) after an alarm signal has been given.
  • both the duration of the sleep and the number of possible alarm signal outputs before initiating the sleep time can be predetermined, although only one another alarm trigger, but not a signal extension is possible.
  • the sleep time of the motion detectors can, for example, be set in 3 steps between 1 and 6 minutes.
  • an evaluation can be carried out in such a way that an alarm signal must be received on both frequency channels in order to cause an alarm, unless one of the frequency channels is disturbed by an external signal.
  • An external signal interference on one frequency channel combined with the reception of an alarm signal on the other frequency channel can be evaluated as an alarm condition and thus lead to an alarm.
  • the alarm center 1 evaluates both the alarming and the disturbed frequency channel, it is also possible to put the hazard alarm system into a pre-alarm state for a period of 30 seconds, during which the reception of a second alarm signal from the corresponding or another motion detector leads to an alarm.
  • An intended external signal interference with the aim of blocking the hazard alarm system can therefore be reliably distinguished from an unintentional external signal interference.
  • the above-mentioned measures can significantly reduce the susceptibility to interference with external signal interference from external electromagnetic interference sources.
  • the hazard alarm system can also be operated in the single-frequency operating mode, each of the alarm devices emitting an alarm signal, a sabotage signal or a battery discharge warning signal on one frequency.
  • the reception of one of these signals by the control center 1 leads to a corresponding signaling.
  • an external signal fault leads to a display and / or a delayed alarm if the fault persists for more than 30 seconds.
  • so-called detector monitoring can also be carried out, in which the notification devices emit a notification signal at a random point in time within a predeterminable period of time, for example 6 hours, and thus signal their operational readiness.
  • an alarm monitoring fault signal is generated which indicates an alarm group belonging to the alarm device concerned.
  • the generation of the detector monitoring fault signal can result in a full alarm or a fault display by means of a visual display when the danger alarm system is subsequently deactivated.
  • the hazard alarm system can be radio-controlled or wired.
  • the key switch 110 has three switch positions for deactivating, partially activating (internal alarm) or resetting the hazard alarm system.
  • the receiving unit 10 of the signaling center 1 comprises three wired inputs for fully activating (external alarm), partly activating (internal alarm) or for activating the alarm groups that do not belong to the partly activated (two-zone circuit). These inputs are controlled and monitored, for example, via a switched terminating resistor.
  • the lock transmitter 6 can be constructed in accordance with the contact detector, with the exception of the lock monitoring input, which is replaced by an input for a remote key switch contact.
  • the lock transmitter 6 can transmit both an activation and a deactivation signal to the alarm center 1 and can be programmable in such a way that it emits a signal for partial or full activation of the hazard alarm system.
  • the remote-controlled coding lock 8 enables the system to be activated wirelessly using three different codes, partial activation, full activation or only activation of the detection groups programmed for complete alarming being selectable. A raid report to reporting center 1 is also possible.
  • an external signal checking system consisting of a test transmitter and a test receiver 24 can also be provided, the test transmitter being able to be arranged in the reporting center 1.
  • the test receiver 24 which in turn can contain a transmitting device and thus performs a transponder function, is preferably arranged within the monitoring area of the hazard alarm system at a distance from the alarm center 1 that corresponds to the greatest radio range of the system.
  • test transmitter If the control center 1 receives an external signal, the test transmitter is activated, which then sends a test signal on one or two frequencies depending on the operating mode.
  • the test receiver 24 receives the test signal and, if received sufficiently, in turn sends one or more test signals back as an acknowledgment.
  • Acknowledgment can also be made via a wired signal, which, however, increases the installation effort for the hazard alarm system.
  • the transmission path for alarm signals is blocked and an external signal can be displayed regardless of the occurrence of an alarm-relevant event, so that early warning of the blocking of the hazard alarm system is made possible.
  • two radio test signals of different frequencies corresponding to the signal signals are emitted by the test transmitter of the central alarm unit 1 and both frequency channels are checked for blocking.
  • An external signal interference is thus not only detected, but also evaluated with regard to its effect on the transmission channel.
  • a sleep time of, for example, 3 minutes can also be programmable.
  • the contact detectors 20 can be programmed in such a way that opening and closing signals or only opening signals are emitted.
  • the contact detectors 20 can also have a wired input for a glass break sensor and an integrated evaluation circuit for evaluating the signals emitted by the glass break sensor, so that an additional Message signal can be given in the event of glass breakage
  • the smoke detector 22 is also deactivated for 3 minutes (sleep time) after an alarm signal has been given. This prevents the smoke detector 22 from immediately re-alarming in an alarm state since there is still smoke in its measuring chamber. Such an ongoing alarm signal could lead to interference with other alarm signals.

  • the universal receiver can have a metal housing with externally arranged antennas and 10 outputs such as relay outputs, the states of the relay outputs being able to be indicated by means of light indicators arranged on the housing such as LEDs.
