Definitions

  • the present invention relates to a device for monitoring a two-wire line, in particular a two-wire line of a fire protection system and an associated method and an associated control module.
  • fire protection systems for example for fire detection and alarm generation, must be certified and, in particular, the compatibility of system components must be assessed.
  • a resistance of a two-wire line to which subscribers, such as alarm devices and / or tripping devices is not above a certain value in order to be able to provide sufficient current or voltage in the event of tripping and not to jeopardize the tripping.
  • a series resistance R L in the longitudinal direction of the line and a parallel resistance Rs between the two lines can be described. Too high a series resistance R L means that the voltage applied between the lines is insufficient to trip subscribers, for example valves. At the same time, it must be ensured that the parallel resistance Rs does not become too small, which would correspond to the case of a short circuit of the two lines.
  • EP 2 804 163 relates to methods for measuring a line resistance RL and thus for determining disturbances of control lines in such a hazard detection and control system.
  • the system is not able to determine a parallel resistance between the two lines in addition to a series resistance of the line. In other words, the system makes it possible to determine only one of the two interesting resistance values or a total value resulting from both values.
  • EP 2 916 303 A1 proposes a control device and a control method for a fire detection system, wherein the control device and the control method are capable of monitoring an on-line impedance or an inter-wire impedance of field wires.
  • the device is connected to a line with a capacitive element connected to a remote end of the line.

  • a notification device circuit wherein the notification device circuit includes a first and a second analog input terminal, wherein the notification device circuit has a first and a second external input
  • the notification device circuit includes a line end resistor.
  • the Current may be routed through the notification device circuitry to input terminals, and the voltage may be measured at each of the first and second external output terminals.

  • the control unit By virtue of the passive termination component according to the invention having a chargeable energy store, it is possible for the control unit to charge the loadable energy store by means of the constant current source.
  • the detected voltage profile which is evaluated, for example, both during and after the operation of the constant current source, allows both a determination of the series resistance and the parallel resistance of the two-wire line in a simple manner, since the course of the voltage depends on basic resistances of the same resistances. While the measuring current is being supplied, the chargeable energy storage is charged, so that an increasing voltage is established. Without provision of the measuring current, the parallel resistance of the two-wire line together with the terminating component will form a closed circuit and lead to a self-discharge of the loadable energy store.
  • the voltage waveforms detected during the provision of the measurement current and during a time when no measurement current is provided can be used to infer both the parallel resistance and the series resistance.

  • all loadable energy stores can be used for the method, which have a differential equation equivalent to the capacitor for the loading and unloading process.
  • the capacitor has a capacity which is above 0.1 pF, in particular above 1 pF and particularly preferably in the range from 1 pF to 10 pF. With a capacitance in the preferred range, it is ensured that the charging carried out by the measuring current as well as a self-discharge of the capacitor can take place in an order of magnitude which satisfy an effective determination of the line resistance according to EN54 part 13.

  • the control unit is adapted to the voltage waveform in response to a change in the provided measurement current evaluate.
  • control unit is configured to charge the loadable energy store during a predetermined first time period by driving the constant current source and to evaluate a self-discharge of the loadable energy store during a subsequent second time period after switching off the constant current source.

  • the termination component 10 according to the invention has a chargeable energy store 12, which in the example shown is designed as a capacitor with a capacitance C.
  • the passive termination component 10 does not show a temperature dependency of the determination, so that the capacitance C can be determined automatically, which is why no configuration / measurement of the termination component 10 is necessary.

  • these four voltage profiles 310, 312, 320, 322 coincide with two voltage profiles 314, 324, since the time behavior of the self-discharge is independent of the series resistance RL.
  • the turn-on and turn-off of the constant current source 20 From the jumps 330, 340, which can be detected in the voltage curve U1, the line resistance can be determined directly.

  • the discharge time must be selected only so long that the loadable energy storage device 12 is completely discharged at the beginning of the next measurement.
  • the three-part measurement profile explained above and outlined in FIG. 2 is preferably repeated periodically for determining the resistance values. For each measurement there are discrete voltage values that can be divided into charge and self-discharge.
  • An advantage of the solution according to the invention lies in the short time required for the detection of a disturbance, which lies in the range of a few milliseconds.
  • the voltage curve U (t) is subdivided in the following for further processing in the time periods T1, T2 or T3 corresponding measured value profiles U1, U2 and U3. There are therefore in particular measured value vectors U1 and U2 from the voltage detection unit 30, which are detected during the periods T1 and T2.
  • the goal of the following calculations is to determine from U1 and U2 as exactly as possible the parameters RL and Ps as well as C at the same time. For this purpose, the equations (2) and (3) are considered, in which these parameters
  • Equations (2) and (3) define the time profile of the voltage values, whereby the parameters which best simulate the curve are determined by an approximation or approximation.
  • the least-square method first sums the squares of the individual measurement errors e t into a sum Q, which depends on the two parameters a and ⁇ . The subsequent minimization of this sum leads to the best estimates a, ⁇ for the parameters a and ⁇ -.
  • equation (3) is first used for the self-discharge process during the period T2, since this is influenced only by two of the three parameters. For the sake of simplicity, the timing at which the constant current source 20 is turned off is shifted to the time zero: t
  • Equation (4) the now linear form can be seen with respect to t. This means that all detected voltages U2 are first logarithmized. The least square approach can then be easily applied to these values, cf. Equation (4).
  • Equation (2) already described the voltage curve of the charging process. Moved to the time zero and using the time constant t, it can be written as
  • This exponential curve has an offset in contrast to the discharge curve. It can not be calculated directly with the least squares approach.
  • Equation (7) can therefore be transformed into a linear form, cf. Equation (8), to be rewritten:
  • the corresponding exponential function only has to be calculated with the known time constant t for each time value.
  • the durations T1, T2 and T3 can be, for example, in the range of fractions of milliseconds, in particular 0.1-1 ms, and particularly preferably 0.5 ms, or a few milliseconds.
  • the short measurement time allows a reasonably high rate of repetition of the measurement.
