Definitions

  • the invention relates to a hazard alarm system according to the preamble of patent claim 1.
  • Danger alarm systems for example fire alarm systems, usually have a larger number of Gefaluenmeldern, which are connected to a two-wire signal line.
  • This can be designed as a branch line or as a loop, via which the individual detectors communicate with a control center.
  • Each detector has a sensor or the like which produces measured values in dependence on parameters of its environment.
  • the measured values are transmitted via the line to the control center, which usually polls the individual detectors cyclically.
  • the address is stored in a non-volatile memory of the detector.
  • the message addresses are stored in the processor of the control center so that the control center can monitor the individual detectors with the aid of a suitable program.
  • test circuit arrangements which are connected to the signaling line, for example for checking short-circuit faults or reverse polarity of lines. It is off DE 29611600 U1 an arrangement for testing an alarm system is known in which a plurality of speakers is connected to a central control device. Via a third line, a test unit provided with an address for each loudspeaker is connected to the control device for checking the loudspeakers and their lines.
  • the invention has for its object to provide a hazard alarm system in which a variety of errors can be detected and located in a simple manner, the cost of the test circuit and the cost of measurement are minimal.
  • a test circuit arrangement is provided which is part of the control center and, for example, checks the operational state of the network of the hazard alarm system on a special command of the central control processor. This is done with the help of at least one test unit that contains its own test processor in which a test program is stored.
  • a controlled by the test processor switch assembly is provided for selectively connecting the at least one test unit with the reporting line.
  • the measuring means for checking the operable state of the alarm system are integrated into the central office, so that in connection with an intelligent evaluation software installation errors can be detected quickly and effectively.
  • Frequent faults in alarm systems include polarity reversal of the wires, exceeding of permissible cable lengths, short-circuiting or touching of wires or shields as well as permutation of detector types and deviations from the installation plan as well as changes in contact resistance.
  • test circuit arrangement wherein all test units are connected to a test processor.
  • this can be provided redundantly.
  • the test circuit arrangement is designed as a module, for example in the form of a plug-in card, on which all components of the test circuit arrangement are arranged.
  • the test circuit arrangement has a modem connection for checking the network via a remote connection.
  • a remote connection for example the telephone network, for example.
  • the check can be started from a remote location, for example the place of manufacture of the hazard alarm system.
  • the results obtained during the check, in particular the errors found, can then be read out and transmitted via the remote connection to the remote location. In this way, for example, installation errors can be detected and remedied even before the final commissioning or acceptance of the hazard alarm system.
  • the test unit according to the invention for the detection of impermissibly large cable lengths provides a constant current source, which is connected via a modulator and a controllable switch to the line. Using a data word generated by the test processor via a modulator and also containing the address of a detector, a detector can be controlled and a cross-switch can be made to connect the wires of the line.
  • the constant current source limits the current on the line to a predetermined value, and a voltage measuring device can measure the total voltage drop across the shorted section of the line.
  • the voltage drop caused by the lines results from the difference of the measured voltage drop and the sum of the voltage drops at the detectors of the measured section and, if necessary, a measuring resistor over which the constant current flows to ground. If the voltage drop, which is determined solely by the line length, is known, the resistance of the line length can be determined, because the cross section of the line is known. From the determined in this way resistance for the lines of the measured section can therefore also determine the length of the measured section. In this way, the total length of a line can be determined. It is also possible in the manner described above to determine the length of line sections between selected detectors by sequentially closing the cross-switches in the detectors delimiting the line section.
  • the data word for controlling the individual detectors and for closing the cross-switches is preferably voltage-modulated according to an embodiment of the invention.
  • the detector is usually a logic circuit and a demodulator, so that the selected or addressed detector detects when it is given a command to close the cross switch. It can also be provided a timer, which opens after a predetermined time, the cross switch again, the line length can be established for another section between detectors.
  • Cables for the described networks often have a shield in the form of a braid or a conductive foil, which surrounds the wires of the lines.
  • Such a shield has a very low resistance. It is either grounded or at a predetermined potential. It can happen especially in the field of detectors during installation that a wire touches the shield and thereby causes a short circuit. With the help of the test unit for a so-called. Shield monitoring, such a short circuit can be determined. In a simple way, this is done according to the invention in that the potential of the shield is monitored by the test processor. If the potential deviates from a predetermined value, there is a contact between a wire and the shield.
  • an embodiment of the invention provides that the shield is connected via a measuring resistor with a potential source.
  • the test circuit arrangement has a constant voltage source. This ensures that in the case of the short circuit described limited in the amount of predetermined current flows through the line, via the short circuit point and the measuring resistor.
  • the total voltage drop is essentially composed of the voltage drop from the line sections and the measuring resistor.
  • the shield hardly contributes to a voltage reduction and can therefore be neglected. Since the voltage drop across the measuring resistor is known, can be calculated in this way, the voltage drop caused by the line.
  • the length of the line from the central office to the short circuit point is already an essential statement, which makes it easier to find a short circuit point. It is even easier if it can be determined between which adjacent detectors a short circuit has occurred. In the method described above, the length of the line sections between the detectors can be determined. If the individual cable lengths are therefore stored in the test processor, it can then be calculated between which detectors there is contact between the shield and the wire or the short circuit
  • ring lines are often used, the ends of which are each connected to symmetrical circuits of a central office. It is therefore possible to operate a loop from both ends, for example when it is interrupted in the region of the short circuit.
  • z. B. from one central portion of a stub and operated by the other central portion of the other spur line.
  • an embodiment of the invention provides that the detectors have in series with lying on the wire circuit breaker for separating the line on both sides of a short circuit point. In normal operation, the disconnectors are closed, but are opened by command from the control panel. Since the control panel "knows" between which detectors there is a short circuit, the detectors adjacent to the short circuit can be activated in order to open the circuit breaker.
  • a test circuit arrangement is shown, which is arranged within a dashed box 10 shown.
  • the test circuit arrangement 10 is part of a not shown control center of a hazard detection system having a loop.
  • the line A consists of the wires 12 and 14, and in the course of the line A a series of detectors M to M n is connected.
  • the detectors M1, M2 and M n are shown. Part of the circuit of the detector M is in Fig. 2 played.
  • the detector M further comprises a modulator / demodulator 16, which converts a voltage pulse on the line line into logic signals for a logic circuit 18.
  • the logic circuit 18 includes an address memory and a plurality of input / output lines. It receives a serial data signal (eg, an address or an instruction) and executes an instruction when a received address matches the address stored in the logic circuit 18. This can be z. B. be the case to actuate the cross switch T3 and thus short the wires 12, 14.

  • the test processor 20 controls the modulator 28 and the switch 30 to operate z. B. to give a voltage modulated data word on the line when the switch 30 is closed.
  • Another switch 33 also controlled by the test processor 20 (S 2A ), connects the wire 12 to ground when closed.
  • a voltage measuring device 36 (A / D1 A ) is connected to the wire 12 and its output is connected to the test processor 20. The same is true for a voltage measuring device 38 (A / D2 A ) connected to the wire 14.
  • the wires 12, 14 are surrounded by a shield 40, which in Fig. 1 indicated by dashed lines.
  • the shield 40 is connected to a shield check unit 42 whose output is connected to the test processor 20. It contains a test resistor 44 (R A ), which is connected to the shield 40 and with the other terminal to the potential U s .
