Definitions

  • the present patent application for industrial invention refers to an elevator alarm and management system.
  • Elevators are normally provided with alarm systems that allow a person trapped in the elevator to send an alarm signal to a remote control station and establish a conversation with the operator of the control station.
  • the person trapped in the elevator may be given suitable instructions before a rescue team arrives on site and rescues the elevator trapped occupant.
  • figure 1 is the block diagram of a traditional alarm system for elevators.
  • Traditional systems comprise an alarm management central unit (1) housed in the traditional elevator machine room and provided with an alarm activation device (2) installed aboard the elevator, composed of a bi-directional conversation unit (2a) (normally defined as "handsfree unit”), basically consisting in a microphone and a loudspeaker.
  • alarm management central unit (1) housed in the traditional elevator machine room and provided with an alarm activation device (2) installed aboard the elevator, composed of a bi-directional conversation unit (2a) (normally defined as "handsfree unit"), basically consisting in a microphone and a loudspeaker.
  • the same telephone connection is also used to establish communication by means of the handsfree unit (2a) between the person trapped in the elevator and the operators of the remote station (5).
  • the same alarm management central unit (1) can activate suitable acoustic and/or luminous signals (3) located outside the elevator in order to reveal the problematic condition of the person who is calling for help.
  • the alarm signalling units (3) are provided with auxiliary digital inputs or outputs (3a).
  • the said inputs and outputs can be used to switch on an indicator light inside the elevator to indicate that a call for help was sent to the remote station.
  • Traditional elevator systems also comprise an electronic board (7) installed in the elevator machine room, used to programme the main operation modes of the elevators.
  • the electronic board (7) is normally programmed on site by a specialized technician, who needs to operate in the small, uncomfortable space of traditional elevator machine rooms.
  • the first purpose of the present invention is to devise an elevator alarm system provided with the traditional functions, which is also capable of interfacing with the electronic board responsible for the general operation of the elevator in order to permit remote programming and control of the electronic board over a telephone connection.
  • the second purpose of the same invention is to improve the conditions for "on site” programming of the electronic board; in particular, wireless programming is provided to save technical operators the trouble of working in the small, uncomfortable machine room where the electronic board is normally installed.
  • Another purpose of the invention is to enable the elevator system to periodically execute an automatic test on the efficiency of the handsfree unit installed aboard the elevator.
  • fig. 2 is the block diagram of the new system of the invention.
  • the system of the invention is based on a basically traditional principle, which comprises an alarm management central unit (2), an alarm actuation device provided with handsfree unit (2a) and a series of external devices (3) for acoustic and/or luminous signalling of the alarm status; it being also traditionally provided that the alarm management central unit (1) is connected over the public telephone network (4) with a remote control station (5).
  • the first peculiarity of the system of the invention is represented by the fact that the alarm management central unit (1) is interfaced with the electronic board (7) that is normally responsible for the general management of the elevator.
  • the central unit (1) is provided with an internal modem (1a); in this way, the operators of the remote control station (5) can establish a "distance communication" not only with the alarm management central unit (1), but also with the board (7) used to manage the elevator in order to program the board (7).
  • the electronic board (7) can be programmed from remote without the need to connect to other dedicated telephone lines or without the use of additional modems.
  • the present invention makes it possible for the first time to execute "telecontrol” and "teleprogramming" of the elevator operating parameters, using the alarm system installed in the elevator.
  • the new distance control and programming logics of bi-directional type allows to send commands to the electronic board (7) and read the information coming from the board (7).
  • the same electronic board (7) can also be advantageously used to manage alarm situations, in view of the higher data processing capabilities compared to the central unit (1) that is traditionally designed to manage emergency situations.
  • the electronic board (7) of the elevator can also be used to send alarm or warning signals directly to the remote station (5), also in automatic mode, without the intervention of the person trapped in the elevator.
  • the electronic board (7) can request the alarm central unit (1) to send predefined messages to the elevator cabin, by means of the bi-directional communication device (2a).
  • the system of the invention allows quick programming on site of the alarm management unit (1) and of the electronic board (7) of the elevator.
  • the alarm management central unit (1) is provided with a bluetooth module (1b) designed to communicate with a computerised terminal or cellular telephone provided with a bluetooth interface.
  • the operator in charge of programming the system can make a wireless connection with the alarm management central station (1) and consequently with the electronic board (7) of the elevator for programming purposes.
  • the wireless connection provides additional advantages, since it permits the operator to "penetrate" the alarm management central unit (1) and execute the following operations:
  • the new system of the invention is also capable of automatically testing the operation of the handsfree unit installed aboard the elevator on a periodical basis.
  • the handsfree unit (2a) can generate an acoustic signal ("beep" sound) at predefine time intervals designed to be transmitted by the loudspeaker.
  • This acoustic signal is designed to be captured by the microphone of the handsfree unit (2a) and sent to the central unit (1), where it is verified by a suitable electronic device (1c).
  • the central unit (1) will consider the handsfree unit (2a) to be perfectly operating if the acoustic signal coming from the loudspeaker of the unit (2) is emitted with the correct quality.
  • the central unit (1) verifies the absence of the said acoustic signal or the lack of quality of the same signal, the central unit (1) will send a specific alarm message to the remote control station (5) to inform the operators, who will take immediate action to remedy the detected fault.
  • An additional advantage of the system of the invention refers to the introduction of excellent bi-directional conversation modes, with higher efficiency compared to traditional systems.
  • the bi-directional conversation system of the invention is of typically telephone type.
