Definitions

  • the present invention is relative to an alarm system for an area to be monitored, in particular a commercial or industrial area, such as a construction site.
  • alarm systems which are suited to warn the people standing in an area to be monitored, in case in a monitored region of said area there occurs a dangerous event or an event that can potentially jeopardize the safety of the monitored region or of the whole area.
  • alarm systems are generally used in commercial or industrial areas. In particular, they are used in construction sites having a wide working area, where operators often have to quickly and effectively transmit information concerning events that can put at risk the safety of other operators, even if they are standing in monitored areas that are different from the area in which the harmful event took place.
  • the object of the present invention is to provide an improved alarm system, which, in particular, can be produced in a simple and economic fashion.
  • number 10 indicates, in both figures, two explanatory embodiments of an alarm system according to the present invention.
  • Alarm system 10 is suited to control an area to be monitored, in particular a commercial or industrial area, such as a construction site. Though, as a person skilled in the art can clearly understand, system 10 can also be effectively used in working places other than construction sites.
  • System 10 comprises a master device 12 and a plurality of slave devices 14, which are controlled by said master device 12.
  • the architecture of system 10 is of the so-called "master/slave" type, in which slave devices 14 are configured to work in an autonomous manner, but master device 12, in predetermined operating conditions, is configured to take on a control role with respect to the plurality of slave devices 14.
  • master device 12 can have the same structure and, if necessary, the same look as slave devices 14 and, if necessary, can be selected among one of slave devices 14 themselves, but, during the installation of system 10, it is configured to take on the attitude of a master device 12.
  • each one of slave devices 14 and, if necessary, also master device 12 can be installed in a respective region or partition of the area to be monitored and comprises:
  • Each one of slave devices 14 is configured to activate its own signalling apparatus 16 and to transmit an emergency signal to master device 12 when its own control organ 18 is activated.
  • master device 12 is configured to transmit an activation signal to a series of said slave devices 14 when it receives the emergency signal.
  • master device 12 is programmed to transmit the activation signal to all slave devices 14 when it receives the emergency signal from one of the slave devices in which control organ 18 has been activated.
  • master device 12 can be configured to selectively transmit the activation signal to a series of slave devices 14 that can be determined as a function of slave device 14 that has transmitted the emergency signal according to predetermined criteria.
  • the activation signal can be transmitted to those slave devices 14 that are installed in regions that are adjacent to slave device 14 that transmitted the emergency signal to master device 12.
  • the signal generated by one of slave devices 14 can be shared and used to automatically activate one or more signalling apparatuses 16, thus enabling the warning and the evacuation of the people standing in the regions affected by the alarm indications emitted by means of system 10.
  • Each one of slave devices 14 is configured to activate its own signalling apparatus 16 when it receives the activation signal transmitted by master device 12.
  • Master device 12 and slave devices 14 are configured to transmit and receive said emergency signal and said activation signal through a wireless telecommunication network, for example a WLAN local network. In this way, there is no need to wire one or more data transmission lines that would allow a wire communication between master device 12 and slave devices 14.
  • devices 12, 14 are connected to one another, by way of example, through a a telecommunication network of the mesh type and of the linear type respectively.
  • the telecommunication network uses a radio wave communication channel.
  • the above-mentioned communication network uses a series of standard communication protocols of the ZigBee type, namely based on the IEEE 802.15.4 technological standard. In this way, one can obtain different advantages, among which:
  • system 10 comprises, furthermore, a warning device, which is controlled by master device 12 and is configured to transmit an aid signal, for example through an external telecommunication network, when said master device 12 transmits the activation signal.
  • a warning device which is controlled by master device 12 and is configured to transmit an aid signal, for example through an external telecommunication network, when said master device 12 transmits the activation signal.
  • the above-mentioned warning device is a phone dialer, which is configured to transmit the aid signal through an external telephone network, for example a mobile phone network, such as the GSM network.
  • an external telephone network for example a mobile phone network, such as the GSM network.
  • the warning device is manufactured ad a module that is built-in in master device 12.
  • At least one of slave devices 14 comprises a sensor apparatus, for example a smoke or gas detector, which is configured to detect emergency conditions representing a danger occurring in said region in which said slave device 14 is installed.
  • Slave device 14 is configured to activate its own signalling apparatus 16 and to transmit, through the wireless telecommunication network, an emergency signal to master device 12, when its own sensor apparatus detects the above-mentioned emergency conditions (for example, the break out of a fire or a gas leak).
  • master device 12 substantially acts as if the emergency signal were transmitted by slave device 14 after the activation of control organ 18; in other words, master device 12 transmits the activation signal to a series of slave devices 14.
  • master device 12 is configured to transmit, through the wireless telecommunication network, a deactivation signal to said slave devices 14, when master device 12 is manually switched by an operator, who, by way of example, acts on a pressure-operated push-button for an extended amount of time (for example pushing it for an amount of time ranging from 30 to 40 s) or activates a key switch.
  • Each one of slave devices 14 is configured to deactivate its own signalling apparatus 16 when it receives the deactivation signal. In this way, system 10 can be quickly restored in order to go back to the normal operating mode after the cause of the danger has been properly removed.
  • At least one device of the assembly made up of slave devices 14 and of master device 12 is configured to be supplied with power by an external power supply network and comprises a power supply indicator 20, adapted to provided a detectable warning concerning the connection of respective device 12, 14 to the power supply network.
