Definitions
- the invention relates to a method for radio transmission of Measurement data from alarm sensors of a radio hazard alarm system according to the preamble of claim 1.
- Current radio hazard detection systems currently prefer to work in the frequency domain 433 MHz.
- a central unit is with one Radio receiver equipped, the associated signaling sensors (for Example fire detectors and motion detectors) with a radio transmitter, which sends a radio telegram to the control center in the event of danger sends.
- the radio transmitter normally transmits daily a function message.
- the disadvantage of this unidirectional Radio transmission is conditional on its susceptibility to interference due to the large range of radio transmission (> 150 m) and the intensive use of the 433 MHz frequency band very many radio services (radio amateurs, remote control, cordless Headphones, etc.).
- the object of the present invention is a improved process for the transmission of measurement data from signaling sensors specify.
- This task is accomplished through a method of transferring Measurement data with the characteristic features of the main claim solved.
- Each signaling sensor has its own transceiver. Instead of the reporting data of the reporting sensors Transfer directly to the central unit are in the invention Process this data via neighboring alarm sensors passed in the form of a radio transmission chain. Due to the smaller distance to be bridged between neighboring ones Signal sensors compared to the distance to the central unit frequency bands can also be used with which can only be bridged over shorter distances. It frequency bands around 2.4 GHz and 5.8 GHz, for example in question. The 5.8 GHz range in particular is currently very high little burdened. There are also significantly wider frequency bands to disposal. Compared to 2 MHz at 433 MHz, there are 83 MHz in the 2.4 GHz band and 150 MHz in the 5.8 GHz band.
- the predetermined sequence of transmission and Receiving times ensures that the transceiver of the individual signal sensors only for a short time are in operation, so that a battery supply to the signaling sensors is made possible.
- Radio hazard detection systems according to the invention can also be used use very flexibly because the individual transmission paths between the signal sensors are not fixed, but specifically set for the respective application can be.
- a conventional Radio hazard detection system a central unit 1 with alarm sensors 2 connected wirelessly in the form of a central one Receiver device 4 with sensor-side transmitter devices 5 communicates.
- a battery in the alarm sensor 2 6 provided that both the sensor-side transmitter 5 as well as the actual detection device 3, for example a smoke detector or an infrared sensor, with electricity provided.
- the radio hazard alarm system according to the invention shown in Figure 2 also has a central unit 1 on, which is connected to several alarm sensors 2.
- a central transceiver 7 as well as a sensor-side transceiver 8 provided a bidirectional communication between Ensure central unit 1 and alarm sensor 2.
- the signal sensor 2 as well as the sensor side Transceiver 8 is an individual power supply, for example a battery 6 or a solar cell, provided in the message sensor 2.
- the sensor-side transceiver 8 comprises a radio device 11, an alarm clock 12 as a time-controlled monitoring device and a sequence control unit 13.
- the alarm clock 12 ensures thereby that the message sensor 2 and the sensor-side transceiver 8 are not always on, which the battery 6 would be unnecessarily loaded, but switches both the sensor-side transceiver 8 and the alarm sensor 2 only when a transmission is imminent.
- the sensor-side transceiver 8 can the individual alarm sensors 2 of a radio hazard alarm system also communicate with each other, and it can be, for example, a radio hazard alarm system in Build the tree structure as shown in Figure 3.
- the central unit 1 has two radio subsystems FTS 1 and FTS 2 connected, the radio subsystems used for example by the radio transmission distinguish different frequency. In every radio subsystem there are 32 message sensors, which are hierarchical are connected to the central unit 1.
- the alarm sensors connected to the central unit 1 2 form the second hierarchical level H2, which with the Alarm sensors of the second hierarchy level H2 connected alarm sensors 2 form the third hierarchy level H3 etc.
- the individual message sensors become a hierarchy level 2 differentiated by specifying an additional detector number (M1..M8).
- M1..M8 By specifying the radio subsystem, the hierarchy level and the detector number is a unique address of the individual signal sensors 2 guaranteed.
- the concatenation of the individual signal sensors 2 is now ensured that each message sensor 2 both the address of a Message sensor 2 in a next higher hierarchy level such as the addresses of alarm sensors 2 in the next lower one Knows hierarchy levels with which he communicates.
- the message sensors 2 of the middle hierarchy levels therefore serve as Intermediate stations for the transmission of measurement data from the signal sensors 2 of the lower hierarchy levels to the central unit 1.
- Figure 4a are existing connections by broad lines featured.
- Fig.4b is the Time sequence of the associated telegram processing is shown, the identifier telegrams are in a first time period KTN KTN and in the subsequent time period ATN the response telegrams ZS transmitted in fixed time slots.
- Time slots are ZSM in which telegrams are transmitted are represented by wide lines and time slots ZSO, in which no telegrams are transmitted, through thin lines.
- the sequence in normal operation then takes place as follows, for example:
- the central unit 1 starts the transmission by sending an identifier telegram KT as a synchronization signal.
- the identifier telegram essentially contains the address of the central unit 1 as well as further information about the operating state of the radio hazard alarm system, which will be described in more detail later.
- the alarm sensors 2 of the second hierarchical level H2 are switched on by the alarm clock 12 shortly before the identification telegram KT is sent to the central unit 1 and all read this identification telegram KT at the same time.
- the start edge of the identifier telegram KT also serves as the system synchronization point in time, that is, from this point on, all further activities are defined with quartz precision.
- the message sensors 2 of the second hierarchical level H2 send their own identifier telegrams KT in succession; in FIGS. 4a, 4b it is the message sensors 2 with the message numbers M1, M2 and M5.
- the addresses transmitted in the process do not have to be fully occupied. If all addresses are occupied, the messages appear at a predetermined system time interval, otherwise there are corresponding gaps, as shown in Fig. 4b.
- the message sensors 2 of the third hierarchy level H3 receive these identification telegrams and compare them with the stored, assigned address of the message sensor 2 of the second hierarchy level H2, to which they are to transmit their reporting data.
- the alarm sensors 2 of the third hierarchy level H3, like the alarm sensors 2 of the second hierarchy level H2, are switched on by their alarm clocks 12.
- the receipt of the identifier telegram KT from the assigned signal sensor 2 of the upper hierarchy level triggers the measurement process its own detection device 3, so that afterwards a current value can be transferred to it. If all Have sent signal sensors 2 of the penultimate hierarchy level, that is, if the corresponding allotted broadcast time has expired, after a pause the return of the Measurement data started. The pause gives the last message sensor 2 Opportunity to activate its detection device 3. For the return of the measurement data in a reply telegram is AT a fixed time slot ZS is assigned to each signaling sensor. The Data transmission takes place in the reverse order to that Transmission of the identifier telegrams, i.e. it starts first the message sensors 2 of the lowest hierarchy level in a predetermined Order to send.
- the alarm sensors 2 of the upper one Hierarchy levels receive the measurement data from the signal sensors 2 the lower hierarchy and send both their own Measurement data as well as the measurement data received from the signaling sensors 2 of the lower hierarchical levels at the respective assigned Message sensor 2 of the upper hierarchy level continues until the measurement data have arrived in the central unit 1. After the transmission of the response telegram switches the alarm clock 12 the signal sensors to save electricity.
- a single alarm sensor 2 is not ready for operation, then he will not send an identifier telegram KT.
- the regulation applies that the own identification telegram is only for Receipt of the identifier telegram from the assigned alarm sensor 2 of the upper hierarchical level may be sent.
- the associated message sensors 2 of the lower hierarchy levels lame. Because each detector sensor 2 from its parameter set knows the downstream sensor 2, whose Reply telegram AT to the respective message sensor 2 must pass through the upper hierarchy level Signal sensors 2 of the next lower hierarchy level a fixed one Time window allocated for data reception. The receiving one Message sensor 2 now sets these time windows one after the other and tries to receive the measurement data.
- the transceiver In the initiation phase, for example, the transceiver becomes 8 switched on for 50 ⁇ s each and then switched off for 1s. The period of 50 ⁇ s is sufficient to settle the frequency synthesizer to let.
- a continuous signal (approx. 5s) is emitted.
- the essential task this continuous signal consists of all the signal sensors 2 Radio hazard detection system to draw your attention to the fact that there is radio operation at all. So it just comes up level detection, not on the correct reading of the continuous signal.
- Each signal sensor 2 which is a permanent signal from somewhere detected, follows the initiation phase and also sends a continuous signal. Then switches each signal sensor 2 for a longer time (approx.
- FIG 5 is another embodiment of a Radio hazard detection system shown.
- the central unit 1 with individual alarm sensors 2 in type and Connected way that only in each radio subsystem AGVS a message sensor 2 is provided per hierarchy level.
- the individual Signaling sensors 2 spatially so closely staggered that not only the Message sensor 2 of the next hierarchy level, but also the Message sensor 2 of the next but one hierarchy level can be reached is.
- this radio alarm system how already described, first the identifier telegrams KT individual message sensors 2 sent in succession.
- the concatenation consists in the fact that the individual signal sensors 2 not just the identifier telegram of the signal sensor of the upper one Hierarchy level, but also the identifier telegram KT of the Message sensor 2, the two hierarchy levels arranged above is reads. In general, both identifier telegrams KT receive.
- Each detector sensor 2 is sufficient for this normal operation its response telegram AT to the message sensor of the top Hierarchy level continues, as is the case with the tree structure according to the figure 2 and 3 has already been set out.
- Alarm sensor 2 detects that it is from the failed alarm sensor 2 does not receive a response telegram AT, so it sets an additional reception time window for the message sensor 2 two hierarchy levels below, receives the response telegram AT, also sets information about the failed alarm sensor 2, and sends this data along with your own Measurement data than his answer telegram AT.
- the central unit 1 immediately recognizes the faulty one without additional actions Message sensor 2 on the additional information inserted.
- This chained willow branch structure is ideal for the narrow assembly of elongated buildings without large ones spatial interruption.
- the system is well manageable and robust, every second signaling sensor 2 can temporarily Function can be set without the radio hazard alarm system collapses.
- FIGs 6a to 7b Another embodiment is in Figures 6a to 7b shown.
- the individual signal sensors 2 are in one Loop structure built.
- Both AGV radio subsystems are constructed analogously to the willow branch structure, i.e. in each Hierarchy level there is only one message sensor 2.
- Both radio subsystems AGVs work on the same radio channel.
- the message sensors 2 of the lowest hierarchy level are so closely arranged that they are together can communicate by radio.
- FIG 6b is the Time sequence of the telegram transmission in normal operation shown.
- the time slots ZS are each through vertical lines are shown, with time slots ZSM in which Telegrams are sent out by broad lines, and Time slots ZSO in which no telegrams are sent are marked with narrow lines.
- Time ranges KTN are analogous to those described so far Embodiments of the identifier telegrams KT of the individual Signaling sensors 2 are sent, the identification telegrams KT of the two radio subsystems FTS sent so that the identifier telegrams KT of the two systems against each other half a telegram increment are offset.
- the passage of time is also dimensioned so that the knowledge telegrams KT the last two signal sensors 2 in quick succession be sent. This fact is an essential part the loop redundancy and is closer with reference to Figure 7 explained.
- the reply telegrams AT are returned in fourth time period ATN, the individual time slots of the the two radio subsystems AGVs are in turn nested are.
- Intelligent time management makes time for the transmission of the response telegrams AT reduced by the length of the reserved time slots ZS the length of the Response telegrams AT are adapted.
- the query time is unsatisfactory.
- the system can be used in an analog form also use for intrusion detection systems. It is in one larger time interval in the manner already described and Way a function check and a synchronization of the individual signal sensors 2 reached.
- individual time slots are provided in which the individual alarm sensors when detecting a hazard message this to the respective assigned sensor 2 of the upper one Hierarchy level.
- These signal sensors 2 the upper hierarchical level then routes this data accordingly to central unit 1. To do this, the individual Signal sensors 2 in the time interval very precisely their respective Switch on transceiver 8.
- the transceiver detects 8 on missing reception and switches off, otherwise the received message will be allocated in your own Broadcast timeslot passed up one hierarchy level.
- the synchronization of the individual alarm clocks 12 in the Signaling sensors 2 will refer to this repetition time the central unit 1 achieved. Because of the short-term The transceiver 8 can be switched on therefore operate the individual alarm sensor 2 with a battery 6.

Abstract
Description
Die Zentraleinheit 1 startet die Übertragung durch Aussenden eines Kennungstelegramms KT als Synchronisationssignal. Das Kennungstelegramm enthält im wesentlichen die Adresse der Zentraleinheit 1 wie auch weitere Informationen über den Betriebszustand der Funk-Gefahrenmeldeanlage, die später noch detaillierter beschrieben werden. Die Meldesensoren 2 der zweiten Hierarchieebene H2 werden kurz vor Aussendung des Kennungstelegramms KT der Zentraleinheit 1 durch ihre Weckuhr 12 eingeschaltet und lesen alle gleichzeitig dieses Kennungstelegramm KT. Die Startflanke der Kennungstelegramms KT dient zugleich als System-Synchronisationszeitpunkt, d.h., von diesem Zeitpunkt an sind alle weiteren Aktivitäten quarzgenau festgelegt. Im Anschluß daran senden die Meldesensoren 2 der zweiten Hierarchiestufe H2 nacheinander ihre eigenen Kennungstelegramme KT, in Figur 4a, 4b sind es die Meldesensoren 2 mit den Meldernummern M1, M2 und M5. Dabei müssen die dabei übertragenen Adressen nicht lückenlos besetzt sein. Wenn alle Adressen besetzt sind, erscheinen die Meldungen in einem vorgegebenen Systemzeitabstand, ansonsten bestehen entsprechende Lücken, wie in Fig. 4b dargestellt. Die Meldesensoren 2 der dritten Hierarchiestufe H3 empfangen diese Kennungstelegramme und vergleichen sie mit der abgespeicherten zugewiesenen Adresse des Meldesensors 2 der zweiten Hierarchiestufe H2, an den sie ihre Meldedaten übertragen sollen. Die Meldesensoren 2 der dritten Hierarchiestufe H3 werden ebenso wie die Meldesensoren 2 der zweiten Hierarchiestufe H2 durch ihre Weckuhren 12 eingeschaltet. Aufgrund der begrenzten Zeitgenauigkeit dieser Weckuhren 12 muß davon ausgegangen werden, daß diese Einschaltung nicht unmittelbar vor der Aussendung des interessierenden Kennungstelegramms KT erfolgt, es kann also sein, daß zunächst das Kennungstelegramm eines zeitlich davorliegenden Meldesensors 2 der zweiten Hierarchiestufe H2 empfangen wird. Der Meldesensor 2 hat zwischen der Aussendung der einzelnen Kennungstelegrammen KT genügend Zeit für einen Vergleich der Kennungstelegramme KT. Wenn das richtige Kennungstelegramm KT empfangen wurde, erfolgt eine Synchronisation des weiteren Zeitablaufes auf diesen Empfangszeitpunkt, wobei die Zeitverschiebung aufgrund der Adresse des Meldesensors 2 der nächsthöheren Hierarchiestufen berücksichtigt wird. Die weiteren Hierarchiestufen werden analog behandelt.
