Definitions

  • the invention relates to a hazard warning system with a plurality of detectors which can be connected to a central unit via signaling lines, the state of the individual detectors in the central unit being ascertainable via test devices and being able to be displayed via an evaluating device, and wherein the individual detector signals can be queried and evaluated via a programmed controller is.
  • a central data processing system is often used in newer systems to process the large amount of information, but also to reduce the number of components. This is associated with the particular risk that the central assemblies will become inoperable, which will result in the failure of the entire alarm system.
  • the object of the invention is to obtain the advantages of a programmed control for the interrogation and evaluation of the detector signals, but at the same time to keep the risk of failure of such a control as low as possible or to restrict it to the smallest possible part of the system.
  • each of the blocks having its own controller, preferably a microprocessor; This controls all logical processes and processes the detector information that arises at the same time.
  • Each system block has a number of slots in which controller boards for a wide variety of detector types can be inserted. All slots in a system block can be connected to one another by a universal cable bus; in this case, detector interface modules can be inserted in any arrangement.
  • Each system block is expedient partially fed from its own power supply.
  • connection devices in each system block can also have a simple fault and alarm display in parallel with the programmed control for the connected detectors or subordinate system blocks. This serves as a kind of emergency program so that in the event of a processor failure, danger messages can still be recognized on the detector interface.
  • Fig. 1 shows the structure of a hazard alarm system from several system blocks SYB.
  • the system block SYB1 is located in the central office Z. It contains a programmed controller for evaluating the signals arriving from the connected detectors M and the connected, subordinate node K.
  • This programmed controller is generally a microprocessor.
  • a display and operating device AB for example a data display station
  • a registration device RG for example a printer
  • Nodes K1 and K2 are connected to the central station Z.
  • the node K1 contains a system block SYB2, to which the system blocks SYB3 and SYB4 are hierarchically subordinate.
  • the subordinate system block can be accommodated in the same node K1 or in a remote node K2.
  • the subordinate system blocks are connected in the same way as the detector M is connected via two-wire lines.
  • Each system block can be provided with display and operating elements AB or with registration devices RG if necessary.
  • the scheme of a system block is shown in Fig. 2.
  • the system block SYB each contains a power supply module SV and a programmed controller PST, which is generally formed by a microprocessor.
  • the system block has a number of slots El ... En for detector connections or for input and output modules. All installation locations are connected to each other and to the programmed control via a universal bus system DB. This means that detector connections to which several lines can be connected can be plugged in any order.
  • Fig. 3 shows the block diagram for a detector connection, such as can be used in a slot E1 ... En.
  • the individual signal lines with the connected detectors can be connected to the KM terminals. Subordinate system blocks are also connected via these KM terminals.
  • the incoming detector signals are brought into a processable form, for example converted into pulses. Such conversion of current measurements into pulses is shown, for example, in DE-AS 2533382.
  • the evaluation AW generally contains comparison devices in which the detector signals are compared with setpoints and processed to form fault or alarm signals. These can be displayed in an activated display and operating device AB or forwarded via a bus interface BSS.
  • FIG. 4 a possible circuit arrangement with the logical links is shown in FIG. 4, as is also carried out by a programmed microprocessor.
  • Individual detection lines L1 ... Ln are connected to the system block SYB shown, to which detectors M1, M2 .. Mn are in turn attached.
  • the signal lines each lead to a detector interface MA1 ... MAn, in which the condition of the line or the connected detectors is checked.
  • a signal r for idle state, a for alarm state or s for fault message appears at one of the three outputs.
  • This interference signal is also generated if both half-waves can be received due to a line short circuit. If no detector is connected to the line, this would also be reported as a fault signal if appropriate measures were not taken.
  • the output signals of the signaling interfaces MA1 ... MAn are queried synchronously via multiplex interrogators, namely the alarm signals a via the interrogator MX1, the fault signals s via the interrogator MX2 and the idle signals r via the interrogator MX3.
  • the serial alarm signals a and Fault signals s are each forwarded via a comparison device VG. This can be done either directly to a display device connected in the system block or via a two-wire line to a higher-level system block.
  • serial incoming fault and alarm signals can be sent to a common line via an OR gate OR2.
  • the signals for the individual detection lines can then be output in parallel on a display device by means of a multiplexer which can be switched synchronously with the interrogation device MX1, MX2 and MX3.
  • a memory SP is also provided in the present example, the individual memory locations Sp1 ... Spn of which are each assigned to a signaling line and in which the busy state is assigned relevant message line can be stored. These memory locations Sp1 ... Spn are scanned synchronously with the detector connections via the multiplex interrogation device MX7, and the signal read out from the memory location is compared in the comparison device VG with the incoming fault or alarm signal. Such a detector signal is only passed on via the coincidence elements AN1 and AN2 if the memory location in question is marked as occupied.
  • a multiplex input device MX8 which also runs synchronously with the interrogation devices MX1, MX2 and MX3. If the actual status of the signaling system is now to be recorded and saved, i.e. during commissioning, then the BT operating button is still open.
  • the AND gates AN1 and AN2 are blocked via the AND gate AN3 and do not allow any signals emitted by the detector connections to pass.
  • an occupied state is written into the memory SP via the OR gate OR1 and the AND gate AN4, when an idle signal r or an alarm signal a is reported by the relevant detector interface MA1 ... MAn. In these cases, a detector is switched on on the relevant reporting line.
  • a fault signal s is reported, a logical 0 is written into the relevant storage location Sp, i. that is, the relevant detector line is marked as not occupied. If the entire memory SP is written, the actual state of the system can be checked via a display device with light-emitting diodes LD1 ... LDn. If this condition is found to be correct, the system can be started using the BT operating button. Now the AND gate AN4 is blocked via the negation gate NE1, so that the memory state can no longer be changed. Fault signals or alarm signals are only passed on via the AND gates AN1 and AN2 if the memory location in question shows the occupied state.
  • Fig. 4 can be performed by a programmed microprocessor with memory on.
  • other detectors such. B. analog indicating detectors are evaluated and compared with setpoints formed in the microprocessor. Since each system block SYB is equipped in the same way with a microprocessor, data traffic between the individual blocks is possible via a standardized serial interface using a single pair of wires.
