Definitions

  • the invention relates to a method for the transmission of measured values in a monitoring system, wherein measured values determined by individual measuring points serving for monitoring and lying in a chain on signal lines are passed to first pairs of terminals in a signaling center, in which they are then linked to obtain differentiated fault or alarm messages and furthermore, when starting up, all measuring points are disconnected by a voltage change in the signal line and then switched back in time to the signal line by switching elements present in each measuring point so that after a certain time delay each measuring point additionally switches on a subsequent measuring point to the line voltage.
  • measuring points are distributed in extensive objects and connected to a signal center via a signal line.
  • the object of the invention is to provide a method and a device for carrying out the method for the identification of measuring points of a transmission system, which avoids the disadvantages mentioned above, in particular to create a transmission system which, with little installation effort , reliably identifies the measuring point , of which measured values are sent to a signal center, whereby identical measuring points, which are connected in a chain to the signal center, can be used.
  • Another on The object of the invention is, according to one embodiment of the transmission system according to the invention, to design the measuring points such that they can be controlled from both sides by the signal center via signal lines arranged in a loop.
  • this is achieved in a method for the transmission of measured values of the type mentioned at the outset in that address memories present in the measuring points are assigned in a predetermined order from the signaling center with the addresses of the corresponding measuring points and then locked before the next measuring point thereof is switched by the switching element Signal line is connected to the signal voltage.
  • the address memory of the newly connected measuring point is filled and then locked immediately, ie locked against reading in further addresses.
  • the switching element switches the next measuring point on the signal line and this further measuring point is in turn ready to receive its corresponding address.
  • This switching on of new measuring points continues until all measuring points of a signal line are provided with their associated individual addresses. This ensures that the originally identical measuring points differ from one another after commissioning. Remote addressing avoids everyone Manipulation at the measuring points themselves and allows the exploitation of both the advantages of the parallel system and those of the series system without having their disadvantages. Of course, the addresses can be read in again at any time in the event of a system failure, malfunction or maintenance.
  • the origin of the signals i.e. the identification of the measuring point from which the signals originate, is possible in the signal center by two methods; first by counting the incremental pulses and second by the measuring point address. By combining both methods, i.e. by comparing the counted pulses with the detector address, a very high degree of security of the measuring point identification can be achieved.
  • the measured values can now be transmitted as described in DE-AS 2,533,382, i.e. the switching elements are actuated with each interrogation cycle. However, the transmission can also take place as in a parallel transmission system, the switching elements remaining closed.
  • a device for carrying out the method according to the invention consists of measuring points which have a measured variable sensor, a measured value converter, a control unit, an address memory and a switching element.
  • Fig. 1 shows the structure of a conventional Ueberwachun g ssy- stems after the chain indexing principle.
  • a signal station Z From a signal station Z, one or more signal lines L go out, to each of which a plurality M essstellen MS are connected.
  • the measuring points substantially MS contain in addition to the measuring sensors and M esswertwandlind a signal receiver, a sequencer, a signal generator and a switching element S m.
  • a timing element starts to run in the measuring point MS 1 .
  • the switching element S 1 closes and applies the line voltage to the second measuring point MS 2 , where a timer also starts to run again.
  • Storage capacitors located in the measuring point ensure the energy supply to the measuring point during any system-related voltage interruptions.
  • each signal line L consists of a two-wire line to which all measuring points MS of a signal line are connected in parallel.
  • Each measuring point MS is characterized by a fixed address A. By sending this characteristic address, the signal center Z can call up any measuring point MS m and, for example, have it output its measured value.
  • the address signals can consist, for example, of a digital pulse sequence, a specific voltage, frequency or tone sequence, or of any combination of these elements.
  • FIG. 3 shows the block diagram of a measuring point MS for use in the transmission method according to the invention.
  • the measuring point MS can be a fire detector, for example an ionization smoke detector, an optical smoke detector, a temperature detector or a flame detector, or a monitoring device in one Intrusion protection system, such as a passive infrared detector, an ultrasound detector or a noise detector, or any measuring point in a transmission system.
  • a fire detector for example an ionization smoke detector, an optical smoke detector, a temperature detector or a flame detector, or a monitoring device in one Intrusion protection system, such as a passive infrared detector, an ultrasound detector or a noise detector, or any measuring point in a transmission system.
  • each measuring point MS there is a directionally symmetrical (bilateral) switching element S which connects the two input / output terminals 1, 2 to one another.
  • a measured variable sensor M In the module B, a measured variable sensor M, a measured value converter W, a control unit KE and an address memory AR are provided.
  • the state of the switching element S is controlled by the control unit KE, which also contains means for signal detection.
  • the control unit KE which also contains means for signal detection.
  • the address A superimposed on the line voltage is determined by switching on the line voltage from the control unit KE and read into the address memory AR.
  • any other individual commands or information can be stored in the measuring point MS; however, the address memory AR is blocked from accepting further addresses A.
  • the measuring points MS are connected to one another and to the signal center Z via the terminals 1 and 3A on the one hand and the terminals 2 and 3B on the other hand, as shown in FIG. 4.
  • the switching element S is directionally symmetrical (bilateral)
  • the measuring points MS can be supplied with power from both sides, ie the signal lines can be connected to terminals 1 and 3A as well as to terminals 2 and 3B of the measuring point MS, which simplifies and increases safety during assembly.
  • the polling direction for the signal line L concerned can be reversed if the signal line L is returned from the last measuring point MS to the signal center Z.
  • the measuring point MS thus remotely addressed is characterized by the stored address A until the voltage supply of the measuring point MS fails or until the signal center Z releases the address memory lock for re-addressing by special control commands and a new address is read.
  • High reliability of the measured value identification is achieved if the address A is transmitted together with the measured value to the signal center Z for evaluation; the signal center Z can monitor the function of the measured value transmission by comparing the expected with the actually read address.
  • the KE control unit also contains a line short-circuit detector for the left and for the right connection terminal. If a short circuit is detected, opening the switching element S prevents the voltage at the terminal which is not short-circuited from dropping below the required operating voltage. This makes it possible to maintain the operation of all measuring points MS up to the line short circuit.
  • the measuring points MS are symmetrical, ie interchangeable, with regard to the connection terminals.
  • a preferred embodiment of the method according to the invention provides that the line is led back from the last measuring point MS of a signal line L to the signal center Z.
  • the monitoring of the measuring point MS can now take place from two sides. This makes it possible in connection with the short-circuit detector mentioned, in the event of a line short-circuit or interruption Maintain data traffic from and to the measuring points MS fully, while reporting the line fault. In this context, it is of great importance that the location of the line fault can easily be determined by the method according to the invention. This is a particular advantage, because it is generally known that finding line faults is very time-consuming and time-consuming.
  • FIG. 4 shows an embodiment of a transmission system according to the invention with measuring points MS which are addressed from the signal center.
  • all measuring points MS m are distributed over one or more signal lines L.
  • the measuring points MS are constructed according to FIG. 3, ie they each contain a measuring sensor M, a measuring value converter W, a control unit KE and address memory AR for storing the measuring point address and other individual commands in the modules B.
  • all switching elements S m are first opened, so that only the measuring point MS 1 closest to the center of a signal line L can receive information from the signal center Z.
  • the control center now sends out the address A 1 on the signal line L, which is received by the measuring point MS 1 and read into the address memory AR 1 .
  • control commands for the measuring point MS 1 can also be transmitted and read into the corresponding memory and stored there.
  • the switching element S 1 After receiving the address A 1 together with any associated control commands, the switching element S 1 is closed, so that the measuring point MS 2 can receive its corresponding information from the signal center Z. Simultaneously with the closing of the switching element S 1 , the address memory AR 1 and possibly existing command memories are locked in such a way that no new information can be read into these memories.
  • the fully addressed system can now be operated like a conventional monitoring system according to the chain advance principle according to FIG. 1, in which each time the switching element S of the measuring point MS m is closed, a current pulse is drawn, which is counted by the signal center Z for the purpose of identifying the measuring point.
  • the address A m is coded together with the measured value and transmitted to the Signalzentrra.le Z, where it is compared with the address determined independently by counting the current pulses. This redundancy makes measuring point identification extremely reliable.
  • Such a monitoring system can be completed by remote addressing, of course, purely as a parallel system of FIG. 2 are operated, must be set in which no addresses by hand to the M essstellen but from the signal station Z out. Furthermore, the remote-addressed system can be operated as a mixed series-parallel system.
