Definitions

  • the present invention relates to a reception/management system for digital signals from electronic devices used, in particular, for alarm systems.
  • the present alarm systems generally comprise an electronic control unit (referred to in the following, by the more common term “central unit”), alarm devices (such as sirens, warning horns, blinkers), specific sensors to the installed system type, telephone diallers, stabilized power supply units, which take the voltage from electrical power distribution mains, enabling or disabling devices, actuators or driver devices for motor units.
  • buss connecting lines of digital type
  • the installer must subdivide the area controlled by the alarm system into several zones each of which can be excluded from control independently from the other zones.
  • Such a configuration is normally accomplished by means of digital signals reception/management systems of traditional type, by connecting the central unit with one or more electrical networks constituted by sensor elements, other electronic devices for auxiliary functions and sound signalling devices (which start operating in the event of a fire) by means of a star-like connection pattern, using purposely designed point-to-point lines, i.e., one line per each zone.
  • the individual sensor element is suitably configured by setting purposely provided setting means said sensor element is equipped with (by acting, for example, on "DIP switches", rotary selectors, resistors).
  • EP-A-0 485 878 discloses a system according to the preamble of claim 17.
  • Each sensor element is defined as belonging to a well determined zone and an univocal correspondence is established between the sensor element and the zone it belongs to ("belonging zone").
  • the sensor elements can be supplied as already provided with an univocal code of their own in order to identify the zone they belong to.
  • One from the main drawback of the reception/management system for digital signals as disclosed above consists in the lack of flexibility of the connections and of the device installations.
  • the sensor element connected with the connecting line of a determined zone can be re-assigned to another zone only by means of a direct electrical connection with the corresponding peripheral unit.
  • the major difficulty consists in that the installer must be supplied with complete information as to the operations to be performed, with the consequent and unavoidable possibilities of error in system setting (due to misunderstanding, information mistakes, staff absence) and long implementation times.
  • the purpose of the present invention is of providing a reception/management system for digital signals capable of learning the zone configuration data which solves the above cited problems, with a coordinated and flexible whole of the various electronic zone devices and a management methodology for the latter being provided.
  • Another purpose of the present invention is of providing a reception/management system for digital signals which is capable of learning the zone configuration data, using standard electric/electronic technologies, communication methodologies and univocal electrical solutions which allow the amount and size of connecting harness to be reduced and the devices to be installed and integrated with a high flexibility degree, with higher functionality of code/zone association and learning accuracy being accomplished as compared to the solution known from the prior art.
  • a not least purpose of the invention is of providing a reception/management system for digital signals which is easy and cheap to be manufactured, without having to resort to either complex or expensive technologies.
  • the system for receiving and managing digital signals uses one single bifilar digital bus with which the central unit, electronic devices, sound signalling devices and zone actuator apparatuses are connected.
  • using one single digital bifilar bus for connecting the electronic devices of an alarm system allows the amount of connecting harness to be substantially reduced and flexibility to be accomplished when installing said devices, which can be assigned to different zones of the system with no need for being electrically connected with the corresponding connecting line.
  • zone attribution no operations are required of zone attribution to be carried out on the individual electronic device with time wastes and error possibilities being thus avoided.
  • the reference numeral (60) generally indicates the alarm system as a whole, which comprises: a power supply unit (20), which feeds the system with a direct voltage comprised within the range of from 20 to 30 volts, encased inside a modular case for flush mount in accordance with the applicable DIN provisions and connected, at the one side, with the electrical power distribution mains (10) and, at its other side, with a bifilar bus (18), through a connection line (19); sensor element (40), appended to other auxiliary electronic devices, actuator and motor units and connected with the bus (18) through connecting lines (19), which acquire and transmit data and information through digital signals of communication with a central unit (30) of the system (60); a central unit (30), connected with the bus (18) through one of said connecting lines (19) and designed to encode the sensor elements (40) assigned to the different zones and to learn said associations; devices for sound signalling (50) connected with the bus (18) through connection line (19), which start operating following commands issued by the central unit (30), in the event of an alarm.
  • a power supply unit (20)
  • the central unit (30), the sensor elements (40) connected with the auxiliary electronic devices, the actuator devices and the motor units, the power supply unit (20) and the sound signalling devices (50) are all provided with terminals for connection with the bifilar bus (18) through the lines (19), and with mechanical elements for fastening to frames/brackets which are used to contain electrical devices for use in civil environment, of modular type for flush mount.
  • the reference numeral (21) indicates an electronic device suitable for receiving an identification code (typically, a LED diode sensible to I.R. wavelengths)
  • the reference numeral (22) indicates an optical alarm display
  • the reference numeral (23) indicates an optical display which displays the operating state of the system applied to the alarm system (60) (i.e., switched on/off)
  • the reference numeral (24) indicates optical indicators which indicate an enabled or selected zone in learning mode
  • the reference numerals (26) indicates push-buttons used to enable a zone and for selecting the zone in learning mode.

  • each sensor element (40) with a zone consists in putting the central unit (30) in a particular learning operating state during which the sound signalling devices (50) are disabled.
  • the zone is selected with which the individual sensor elements (40) making a part of the system (60) must be associated, by acting on the push-buttons (26) for zone enabling selection in learning mode.
  • Suitable optical indicators 22, 23, 24, 28, 29, 31, 32, 33 (typically, LED diodes) visually indicate the selection and the learning operating state of the central unit (30).
  • each sensor element (40) to be associated with the zones of the system and actuates a push-button (46) mechanically sheltered inside said sensor element (40), in order to send an identification code to the central unit (30).
  • the central unit (30) associates the identification code of the device with the selected zone, storing the data in a digital storage element (42) (which is either non-volatile, or buffer-fed).
  • the installer repeates the above said operation for all of the devices to be associated with that particular zone and, then, selects another zone, by acting on the push-button (26) of the central unit (30); the process continues as indicated above, for all of the zone devices which the operator wishes to enable.
  • the identification code sending can be triggered, following a procedure of micro electronic control unit (44) resetting, by means of a physical connection of the sensor element (40) and/or the associated electronic devices, with the bifilar bus (18) and consequent supply with power (possibly preceded by a disconnection).
  • a manual pressure on push-button (46) or the connection with the bifilar bus (18) can generate on the individual device the transmission of the request for identification code to the central unit (30).
  • the central unit (30) sends a specific identification code which the device stores inside its storage element (42) together with the indication of the belonging zone, or without such an indication.
  • the central unit (30) can now store, if so necessary, the association procedure of the generated identification code and the selected zone; such a storage operation takes always place inside the storage element (42).
