Definitions

  • the invention relates to a method for energy saving Operation of hazard detectors in a hazard alarm system according to the preamble of claim 1.
  • Such a hazard alarm system is from DE-PS 25 33 382 known.
  • this alarm system especially fire alarm system, for the transmission of analog detector measured values the individual detectors are connected in a chain to the detection line.
  • the measured values of the individual detectors polled cyclically from the central office and to the central office Evaluation device given to differentiate from there Fault or alarm messages from those to be linked To gain analog values.
  • At the beginning of each polling cycle all detectors are switched off by a voltage change from the Detector line separated and then in the specified order in switched on again so that each detector after one time delay corresponding to its measured value by means of a in one of the wires of the detection line arranged switching transistor the subsequent detector in addition turns on.
  • the detectors will operated from their energy stores during this time.
  • the Energy storage will be in the so-called after the query Rest time with increased line tension.
  • hazard detectors need high quality Sensor technology and transmission technology. Instead of a collective address individual addressing is required, as is the case with above is the case. It can Control commands from the control center to the individual detectors transmitted by the individual detectors be, as is already known from DE-PS 25 33 354. It can receive and receive data from each detector be reported, also in the form of pulse telegrams within certain time slots are transmitted.
  • CMOS complementary metal-oxide-semiconductor
  • special sensors e.g. pulsed the measuring part of an optical stray light smoke detector operate as described in EP-0 125 485-A1.
  • the possibility of all or part of the required energy, e.g. over a own management, which is also the complexity and the cost of a hazard alarm system increases.
  • EP 0 191 239 is a data transmission system for building management systems known, which also includes fire detectors.
  • the sensors of the fire detectors include microcomputers who will retire if none Action of the microcomputer is required. There is none Specified when and how the microcomputer in the active state is switched. It is also not a clue contain about how the startup time of the microcomputer is taken into account which results from the fact that the clock generator must swing for several milliseconds before it is functional.
  • EP 0 093 872 describes a method for transmitting measured values known in a surveillance system that on the principle the chain advance is based.
  • the measuring points connected in series and identified by Counting corresponding advancement pulses.
  • When assigning addresses is activated simultaneously with the locking of one detector switched through to the next detector. Actions that are different Detectors relate to one another in succession.
  • the object of the invention is to avoid the above Disadvantages described a method for energy saving Operating hazard detectors of a hazard detection system, which is a relatively simple and reliable A microcomputer can be switched on and off.
  • the cyclical query receives the A specific voltage (an activation voltage) after each detector, which turns on the microcomputer, but only after one the specified start-up time activates the detector. Then he follows data traffic with the head office, i.e. the detector receives and sends (reports) signals. Then will the microcomputer is switched off. Conveniently the switch-on voltage becomes the query voltage educated.
  • the method according to the invention modifies the known one Chain modulation such that each detector after the Query voltage initially during a specified start-up time remains inactive and then its traffic in one certain reception time and response time with the head office unwinds.
  • the microcomputer is then switched off again. So that is for the microprocessor switched on for an optimally short time and consequently less energy is consumed on average.
  • the Start-up time for the microcomputer is made in a special way won without having a separate start-up time for each detector to have to provide. It will only be a first start-up time required for the microcomputer of the first detector. To the first detector switches on immediately after this start-up time second detector. In the subsequent reception and The first detector's transmission time follows the data traffic of the first detector with the head office. This reception and response time is at the same time the start-up time for the microcomputer of the second detector. This process continues until the last Report off. This procedure reduces the time required considerably and thus extends the available rest period in which the energy stores of the detectors are charged. So that is an increase in the sampling rate and / or an increased energy supply possible.
  • the detector M shown in Figure 2 has in addition to the one Wire of the detection line ML switched-on transistor T the logic logic VL, which is the heart of the detector represents and is formed by a microcomputer.
  • the link logic operates the actual sensor part.
  • the Linking logic VL is from the voltage measuring device MU which monitors the line voltage UL and switching signals according to the applied line voltage the logic logic VL there. This logic logic causes Signals to a control device ST and also signals for switching DS of the switching transistor T, so that subsequent detector is connected to the line voltage.
  • Figure 3 it is illustrated how the individual detectors be turned on in sequence.
  • the line tension UL plotted over time t for detectors M1 to M3.
  • the ML line is on Quiescent voltage UR on.
  • a query cycle then begins with the Disconnect the line from the line voltage UL, i.e. it will for the starting time ts the starting voltage US, which is preferred is zero.
  • the interrogation voltage UA is preferably below this the value of the open circuit voltage UR.
  • For the detector M2 it is shown that he only the after switching DS of the first detector M1 Query voltage UA receives. The same applies to detector M3.
  • the data transmission to the detector generally takes place through Modulation of the line voltage UL in the center, during a Data transmission to the control center by modulating the line current IL is made in the detector.
  • the line voltage UL is the profile of the line voltage UL over time t shown at the input of detectors M1, M2 and M3.
  • the resting tension UR is on for the rest period tr.
  • the interrogation voltage UA which is also the switch-on voltage UAN for the microcomputer is acted upon by the first detector which, after the start-up time tan1 is activated and thus receive signals E1 from the control center for received the reception time te1 and then response signals A1 can report to headquarters in time ta1.
  • the detector M2 in turn activated within the start-up time tan2 and then begins with the data traffic to the head office. Is the primary reporting line ML is queried, the open-circuit voltage UR is sent to the detection line placed.
  • the respective one Microcomputer only switched on for a short time.
  • the microcomputer of the first begins at the interrogation voltage UA To start the detector. During this time, the detector receives received signals E0 from headquarters and could then reply Report A0 to the control center. But neither is possible because the microcomputer is still starting up and therefore not is functional.
  • the functionality is only during of the response time ta0, so that the first notifier for received signal E1 determined him only after this start-up time can receive and edit tan1.
  • the detector M1 With the receipt of the signals E1 from the control center switches the detector M1 immediately to the detector M2 through (DS). During the data traffic of the first detector M1 in the time te1 plus ta1 the start-up time tan2 for the second detector M2, which then switches through to the third detector M3 (DS) as soon as it receives data E2 from the control center.
  • the received signals partly with the voltage level that corresponds to the quiescent voltage, run, which means the energy supply required time advantageously shortened and thus the Number of connectable detectors increased and / or the query is accelerated.
