Description

  The present invention relates to an elevator rescue system for rescuing a passenger trapped in a car due to an elevator failure or the like.

  If the elevator stops for some reason, such as an earthquake, the car stops with the door closed. At that time, if passengers are in the car, they cannot go outside and a so-called “confinement accident” occurs.

  In such a case, an emergency call button is usually installed in the car, and when pressed, the emergency call button is connected to a remote monitoring center of the elevator through a telephone line. As a result, the remote monitoring center hears the situation from passengers in the car and dispatches maintenance personnel to the site to carry out rescue activities.

  However, the emergency call button described above is provided as a means for communicating with the remote monitoring center and cannot be contacted except for the remote monitoring center. For this reason, when a wide-area disaster such as an earthquake occurs and the telephone line cannot be used, the remote monitoring center does not know the situation in the car and the rescue operation is extremely delayed. is there.

  Then, an object of this invention is to provide the rescue system of the elevator which can rescue quickly the passenger who is confine | sealed in the passenger car.

  An elevator rescue system according to the present invention includes a rescue button provided in a car, an indicator lamp installed at a landing, and a lighting control of the indicator lamp by operating the rescue button, so that passengers are in the car. And a control means for informing the situation where the device is confined.

  According to the present invention, it is possible to inform the people at the landing that passengers are confined in the car and request rescue.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an overall configuration of an elevator rescue system according to an embodiment of the present invention. FIG. 2 is a diagram showing an internal configuration of the elevator car, and FIG. 3 is a diagram showing a configuration of the elevator platform.

  As shown in FIG. 1, an elevator hoistway 12 is provided in the building 11, and one elevator 13 is installed there. The elevator 13 includes a passenger car 14, a counterweight 15, a rope 16, a hoisting machine 17, and the like.

  The car 14 carries passengers 30 and moves between the floors of the building 11, and the counterweight 15 has substantially the same weight as the car 14. The rope 16 is wound around a hoisting machine 17, and a car 14 is connected to one end thereof and a counterweight 15 is connected to the other end. Thus, as the hoisting machine 17 is driven, the car 14 moves in a slipping manner in the direction opposite to the counterweight 15 via the rope 16.

  The car 14 is provided with a car door 31 that opens and closes when landing on each floor. In the car 14, an operation panel 32 for performing various operations is provided.

  As shown in FIG. 2, the operation panel 32 is installed in the vicinity of the car door 31. On the operation panel 32, a destination button 33 for each floor for designating a destination floor, a door open button 34 and a door close button 35 for opening and closing the car door 31, and an emergency call button 36 are arranged. It is installed. The emergency call button 36 is an operation button for calling a remote monitoring center 23 described later when an emergency occurs.

  In this embodiment, a rescue button 37 is provided in the car 14 separately from the emergency call button 36. The rescue button 37 is installed for emergency rescue, and is used when the passenger 30 requests rescue from surrounding people. As shown in FIG. 3, “surrounding people” here refers to people in the vicinity of the platform including the user 40 waiting for the elevator 13 at the platform 41.

  In the example of FIG. 2, the rescue button 37 is illustrated on the lower side of the operation panel 32, but the installation position of the rescue button 37 may be on the upper side of the operation panel 32. It may be a place (for example, a side wall) other than the board 32. In short, any position that can be operated immediately when the passenger 30 is confined may be used. In addition, it is preferable to devise such that the installation location can be easily visually recognized even in a power failure state, for example, by applying a fluorescent paint on the operation surface of the rescue button 37.

  On the other hand, a landing door 42 that engages with the car door 31 and opens and closes when the car 14 reaches the landing 41 and a landing call registration device 43 in the vicinity of the landing door 42 are provided at the landing 41. . The landing call registration device 43 is for calling the elevator 13 (car 14) to the landing 41, and normally has up and down direction buttons for designating a destination direction.

  Further, the platform 41 is provided with an indicator lamp 44 and an audio output device 45. The indicator light 44 and the sound output device 45 are installed in a place where the user 40 can easily check, such as the vicinity of the landing door 42.

  The indicator lamp 44 is formed of, for example, a red lamp, and is turned on by pressing the rescue button 37 described above to notify that the passenger 30 is confined in the car 14. The audio output device 45 is provided along with the indicator lamp 44 at the landing 41 and is driven in conjunction with the indicator lamp 44. The voice output device 45 generates a warning sound such as a bell sound or a buzzer sound, or outputs a warning message such as “passenger is trapped in the elevator”, so that the passenger 30 is placed in the car 14. The sound is informed of the situation where is trapped.

  In addition, this indicator light 44 and the audio | voice output apparatus 45 are installed in the platform 41 of a specific floor. The “specific floor” is specifically a reference floor. This is because the standard floor is the most crowded among the floors of the building 11 and the situation where the passenger 30 is confined is most likely to be communicated to the surrounding people.

  On the other hand, each signal of the operation buttons 33 to 37 of the operation panel 32 shown in FIG. 1 is given to the control device 19 via a transmission cable (not shown). The control device 19 is also called a control panel or the like and is provided in the machine room 18 at the top of the building, and performs overall control related to the operation of the elevator 13 such as driving and controlling the hoisting machine 17.

  Furthermore, a signal is output to the control device 19 when a P wave (primary wave) of a predetermined value or more is detected at the lowermost part (pit portion) of the hoistway 12, and the elevator 13 is controlled in the control operation mode. A P-wave detector 20 for operating is installed.

  On the other hand, an S wave detector 21 is provided in the machine room 18 to output a signal to the control device 19 when an S wave (secondary wave) of a predetermined value or more is detected and forcibly stop the operation of the elevator 13. is set up.

  In addition to these earthquake detectors 20 and 21, the elevator 13 is provided with various sensors (not shown). Then, some of the signals output by these sensors are transmitted from the control device 19 to the remote monitoring center 23 via the communication line 22 so that the elevator 13 is always remotely monitored. If necessary, the remote monitoring center 23 may supply a control signal to the control device 19 to perform remote control and remote inspection of the elevator 13.

  FIG. 4 is a block diagram showing the functional configuration of the control device 19, schematically showing the functions of the control device 19 related to the emergency call button 36 and the rescue button 37 in the car 14.

  When the passenger 30 in the car 14 presses the emergency call button 36, the operation signal is sent to the control device 19. When the control device 19 receives the operation signal of the emergency call button 36, the control device 19 accesses the remote monitoring center 23 via the communication line 22, and sets the telephone 14 and the remote monitoring center 23 in a state in which a call can be made. . Thus, when an emergency such as confinement occurs, the passenger 30 can directly inform the operator of the remote monitoring center 23 of the current situation.

  On the other hand, when the passenger 30 in the car 14 presses the rescue button 37, the operation signal is sent to the control device 19. When the control device 19 receives the operation signal of the rescue button 37, the control device 19 controls the lighting of the indicator lamp 44 installed at the landing 41, and the passenger 40 in the car 14 is informed to the user 40 near the landing 41. Inform the situation that is trapped. Furthermore, in order to more reliably convey the confinement state of the passenger 30 to the surroundings, the control device 19 has a function of outputting a warning sound or a warning message by driving the sound output device 45 in conjunction with the indicator lamp 44. .

  In such a configuration, the operation of the system will be described assuming that the elevator 13 is stopped due to the occurrence of an earthquake.

  When an earthquake occurs, P and S waves propagate. Here, since the propagation time of the S wave, which is the main shock, is slower than that of the P wave, a method of operating the elevator 13 in the control operation mode when the P wave is detected is widely known.

  When the P wave is detected by the P wave detector 20, the detection signal is output to the control device 19. By inputting this detection signal, the control device 19 switches the operation mode of the elevator 13 to the control operation mode, and immediately controls the passenger car 14 to stop at the nearest floor and get off the passenger.

  Further, when the S wave propagates following the P wave, the S wave detector 21 detects this. In this case, the S wave is more dangerous than the P wave, so it is dangerous to operate the elevator 13. Therefore, for example, even if the P wave detected earlier is smaller than a predetermined value and the control operation mode is not started, it is common to forcibly stop the elevator 13 forcibly when the S wave is detected. .

  In this way, when the elevator 13 is stopped due to the occurrence of an earthquake, if the passenger 30 is on the car 14, the passenger 13 is trapped therein. In such a case, as shown in FIG. 4, if the emergency call button 36 installed in the car 14 is pressed, the remote monitoring center 23 can be contacted and the operator can be requested to rescue.

  However, the communication line 22 may become unusable due to an earthquake, and the remote monitoring center 23 may not be contacted. In such a case, the rescue can be requested by pressing the rescue button 37 installed in the car 14 separately from the emergency call button 36.

  That is, when the rescue button 37 is pressed, the indicator light 44 installed at the landing 41 is turned on, and a warning sound or warning message is output from the voice output device 45. Thereby, it can be notified to the user 40 of the landing 41 that the passenger 30 is confined in the car 14. The user 40 who knows this situation contacts the remote monitoring center 23 using his / her mobile phone, or contacts the manager of the building 11 or the like, so that the passenger 30 in the car 14 Can take action to rescue you.

  As described above, even when the emergency call button 36 cannot be used, by pressing the rescue button 37, it is possible to ask the people around to rescue. Therefore, even if the remote monitoring center 23 cannot grasp the situation, prompt rescue operation can be expected.

  In the above embodiment, the indicator lamp 44 and the audio output device 45 are installed at the landing 41 on the reference floor. However, the indicator lamp 44 and the audio output device 45 may be installed at all the landings 41 on each floor. good. In this way, the situation of the car 14 can be more reliably communicated to surrounding people.

  Further, it is possible to expect a sufficient effect even if the indicator light 44 is turned on only by operating the rescue button 37 without using the audio output device 45.

  Further, in order to prevent an erroneous operation of the rescue button 37 provided in the car 14, the control device 19 has a function that enables the operation of the rescue button 37 only when the operation of the elevator 13 is stopped in an emergency. May be allowed. In this case, nothing happens when the rescue button 37 is pressed during normal operation of the elevator 13, and the indicator light 44 is lit only when the operation of the elevator 13 is stopped, and further from the audio output device 45. A warning sound or warning message will be output.

  Moreover, although the said embodiment demonstrated as an example the case where one elevator was installed in the building, this invention is not restricted to this, With respect to the building where several elevators are installed Is applicable. In this case, a rescue button 37 similar to that described above is provided for each elevator car (for each car), and an indicator light 44 and an audio output device 45 are installed at the landing 41 corresponding to the elevator car.

  The present invention is not limited to earthquakes, and can be applied to any situation where the operation of the elevator 13 is urgently stopped for some reason and the passenger 30 is confined in the car 14.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various forms can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be omitted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
