Description

  The present invention relates to an elevator call system and an elevator call method, and in particular, by a caller provided in an elevator car by a passenger operating an emergency call button provided on an operation panel in the elevator car. The present invention relates to an elevator call system and method capable of making a call with a telephone in a monitoring center.

  In general, an elevator is provided with a communication device for a passenger trapped in an elevator car to report to the outside. This is for communication with passengers confined in the elevator car due to an abnormality or failure of the elevator, prevention of crimes occurring in the elevator car, and rescue in the event of a disaster such as an earthquake. In the above case, the passenger can talk with the telephone in the monitoring center by operating the emergency call button provided on the operation panel in the elevator car. In a monitoring center, it is common to respond to an emergency caused by this emergency call button on a 24-hour basis with a constant monitor.

  This emergency call button frequently causes erroneous operations or so-called mischief operations. For this reason, the receiving load of the monitoring center increases, and there are cases where the rescue and safety assurance of passengers in the elevator car, which is the original work of the monitoring center, may be hindered.

  The emergency call button may be erroneously operated, for example, when a passenger mistakenly presses the emergency call button with another button provided on the operation panel, or when a drunk person falls down at night and presses the emergency call button. . In addition, the so-called mischief operation includes a case where the emergency call button is operated and escaped immediately before getting off the elevator, and an infant is amused and plays with the emergency call button.

  In order to prevent this erroneous operation and mischief operation, various measures have been conventionally devised. For example, Patent Document 1 discloses an elevator call device that prevents erroneous operation or mischief operation of an emergency call button. Here, a configuration is shown in which a predetermined message is broadcast when a passenger in an elevator car presses an emergency call button, and a monitoring center is called when the emergency call button is pressed again. In other words, it is a policy that the passenger is not notified unless the emergency call button is pressed twice.

  Patent Document 2 discloses an elevator call device that prevents useless telephone line connection due to mischief or erroneous operation. Here, a configuration is shown in which at least one of a passenger in an elevator car pressing an emergency call button for a long time or an emergency call button being pressed a predetermined number of times is detected and connected to a telephone line. That is, it is a measure for preventing mischief and erroneous operation by delaying the operation time of the emergency call button.

  Further, the conventional monitoring center receives a call without determining whether the call is an erroneous operation or a mischievous operation in response to a call from the elevator side via a telephone line. Therefore, the current situation is that there is no need to identify an elevator that frequently causes malfunctions or mischief operations and to take an active solution.

  The policy of pressing the emergency call button again described in Patent Document 1 is that if you lose your mind after pressing the emergency call button once, or if you are disturbed by a suspicious person, you cannot talk to the monitoring center. There was a problem. This measure is not very effective for mischievous operations in which the emergency call button is pressed twice in succession. Further, since the passenger recognizes that it must be pressed again by the announcement, there is a problem that it is difficult for the hearing impaired person to operate.

  Furthermore, the original purpose of the emergency call button provided in the elevator car is, as described above, communication with passengers confined in the elevator car due to an abnormality or failure of the elevator, and crimes occurring in the elevator car. It is prevention and rescue in the event of an earthquake or other disaster. For this purpose, it is preferable to press the emergency call button again, which is a preferable measure because it gives troubles to the passengers in an emergency, induces an operation error, and hinders the quick response of the monitoring center. Absent.

  In addition, the policy of delaying the operation time of the emergency call button described in Patent Document 2 gives extra stress to passengers in an emergency, and induces an operation error, so that the monitoring center can be operated quickly. This is not a preferable policy because it hinders the response.

  Furthermore, the conventional monitoring center can determine only the call from the elevator side via the telephone line, and cannot grasp the actual state of malfunction and mischief operation in the elevator. As a result, it is difficult to develop measures to actively eliminate passenger malfunctions and mischief operations.

  An object of the present application is to provide an elevator call system that solves such problems, easily detects a malfunction of an emergency call button, etc., and grasps the actual usage of the emergency call button for each elevator.

  In order to achieve the above object, an elevator call system according to the present invention is such that a passenger operates an emergency call button provided on an operation panel of an elevator car, and a telephone set provided in the elevator car via a public communication line. An elevator call system for making a call with a receiver at a monitoring center, which is provided in an elevator car and is provided with voice guidance means for guiding an emergency call button operation method to a passenger who has erroneously operated an emergency call button, and an emergency call button erroneous operation. When the emergency call canceling means to cancel and the emergency call button are operated, an emergency call button signal is transmitted to the monitoring center, and if the emergency call canceling means is operated within a certain time after guidance by the voice guidance means, If the emergency call release means is not operated within a certain time after the guidance by the voice guidance means and the emergency call button sending section for sending the call button erroneous operation signal to the monitoring center, the monitoring center A telephone for calling the telephone receiver, a telephone receiver for calling the telephone, and an emergency call button receiving section for receiving an emergency call button signal and an emergency call button erroneous operation signal transmitted from the emergency call button transmission section. , The emergency call button storage unit for storing the telephone call, the received emergency call button signal and the emergency call button misoperation signal as a history, and the number of calls for each elevator car stored in the emergency call button storage unit within a certain period of time And an emergency call button management unit that calculates the frequency of occurrence of an erroneous operation of the elevator car from the number of receptions of the emergency call button signal and the emergency call button erroneous operation signal.

  In addition, the elevator call system includes an elevator car equipped with passenger detection means for detecting the presence or absence of passengers in the elevator car, and the emergency call button transmission unit is a passenger in the car within a certain time after the operation of the emergency call button. If a passenger in the car is not detected by the detection means, an emergency call button mischief operation signal is transmitted to the emergency call button reception unit of the monitoring center, and the emergency call button storage unit stores the received emergency call button mischief operation signal as a history. It is preferable to do.

  In addition, the emergency call button management unit determines the frequency of occurrence of mischief operation of the elevator based on the number of receptions of the emergency call button mischief operation signal for each elevator stored in the emergency call button storage unit within a certain period. It is preferable to calculate.

  In the elevator call system, the emergency call canceling means is preferably an emergency call canceling button provided on the operation panel of the elevator car.

  In the elevator call system, the passenger detection means in the car preferably detects the presence or absence of a passenger using a camera provided in the elevator car.

  Further, in the elevator call system, the passenger detection means in the car preferably detects the presence or absence of a passenger by a sensor provided in the elevator car.

  In order to achieve the above object, the elevator call method according to the present invention includes a public communication line using a caller provided in an elevator car when a passenger presses an emergency call button provided on an operation panel of the elevator car. Is an elevator call method for communicating with a monitoring center handset via an emergency call button. When a passenger presses an emergency call button, an emergency call button signal is sent to the monitoring center, and the voice guidance provided in the elevator car is canceled. When the emergency call button is canceled by a passenger within a certain period of time after guidance by voice guidance, an emergency call button erroneous operation signal is transmitted to the monitoring center. If the emergency call release button is not pressed by the passenger within a certain period of time after guidance by the voice guidance means, the monitoring center handset is called and the passenger talks to the monitoring center for monitoring. The telephone stores the call as a history, and stores the received emergency call button signal and emergency call button erroneous operation signal as the history. The monitoring center stores the number of calls for each elevator car within a certain period, the emergency call button signal, and the emergency call button. The frequency of occurrence of erroneous operation of the elevator car is calculated from the number of receptions of the call button erroneous operation signal.

  Also, the elevator call method is that when it is detected that there is no passenger in the car within a certain time after the emergency call button is pressed by the passenger, an emergency call button mischief operation signal is transmitted to the monitoring center. However, it is preferable to store the received emergency call button mischief operation signal as a history.

  Furthermore, the elevator call method is based on the number of times the monitoring center receives emergency call button signals, emergency call button erroneous operation signals, and emergency call button mischief operation signals stored for a certain period of time. It is preferable to calculate the frequency of occurrence of mischievous operations.

  With the above configuration, the elevator call system transmits an emergency call button signal to the monitoring center every time an emergency call button is operated by a passenger. If the emergency call canceling means is operated by the passenger within a certain period after the instruction by the voice guidance means, an emergency call button erroneous operation signal is transmitted to the monitoring center, and no call is made with the monitoring center. Further, if the emergency call button release signal is not operated by the passenger within a certain period after the instruction by the voice guidance means, a call is made with the monitoring center. With this system, the monitoring center can concentrate on responding to rescue and safety of passengers in the elevator car without dealing with an emergency call button that has been misoperated. Further, the emergency call button storage unit provided in the monitoring center stores the history of the call received by the call receiving means and the history of the emergency call button signal and the emergency call button erroneous operation signal received by the emergency call button receiving means. To do. Thereby, the frequency of occurrence of erroneous operations in individual elevators can be grasped.

  As described above, according to the elevator call system according to the present invention, it is possible to easily detect an erroneous operation of the emergency call button and the like, and it is possible to grasp the actual use state of the emergency call button for each elevator.

  Embodiments of an elevator call system and method according to the present invention will be described below in detail with reference to the drawings.

(Elevator call system)
FIG. 1 shows a schematic configuration of one embodiment of an elevator call system. In the elevator call system 1, an elevator includes a car 31 and a monitoring center 33, and the elevator 31 and the monitoring center 33 are connected via a public communication line 32. The elevator car 31 side of the elevator call system 1 includes voice guidance means 4, a call sending unit 5, and an emergency call button sending unit 6. The monitoring center 33 side of the elevator call system 1 includes an emergency call button receiving unit 8, an emergency call button management unit 9, an emergency call button storage unit 10, and an emergency call button display unit 11.

  As shown in FIG. 1, a car operation panel 17 and a communication device 13 are installed in an elevator car 31. The car operation panel 17 and the communication device 13 may be separate or integrated. The car operation panel 17 includes a speaker 18, an emergency call button 2, an emergency call release button 3, a direction light 20, a car call button 19, a door open button 21, and a door close button 22. The monitoring center 33 is provided with a receiver 7. The monitoring center 33 monitors a plurality of elevator cars 31. In FIG. 1, one elevator displays the car 31 as a representative.

  The emergency call button 2 in the car operation panel 17 is provided for a passenger confined in the elevator car 31 to notify the outside. When the emergency call button 2 is pressed by the passenger, the voice guidance means 4 instructs the speaker 18 in the car operation panel 17 to confirm that the emergency call button 2 has been pressed and to deal with the passenger thereafter. That is, when the emergency call button 2 is pressed correctly, an instruction is made to wait for a call with the monitoring center 33. When the emergency call button 2 is pressed erroneously, An instruction is given to press the emergency call release button 3. This announcement is made from the speaker 18, for example, “Emergency button has been pressed. If there is an abnormality, please wait until the clerk comes out to the phone 13. If it is pressed by mistake, press the release button.” Such an instruction is automatically flowed.

  The emergency call button transmission unit 6 transmits an emergency call button signal to the monitoring center 33 when the emergency call button 2 is pressed by a passenger. As a result, the monitoring center 33 grasps information that the emergency call button 2 has been pressed in the elevator car 31. The emergency call button transmission unit 6 monitors the emergency call button erroneous operation signal when the emergency call release button 3 is pressed by a passenger within a certain period of time after the voice guidance unit 4 gives an instruction for an erroneous operation through an announcement from the speaker 18. Call the center 33. In this case, the telephone 13 does not make a call with the monitoring center 33. Thereby, the monitoring center 33 can grasp information that the emergency call button 2 is erroneously operated in the elevator car 31. This fixed time is measured by the timer 16 and is set to 5 to 10 seconds in the present embodiment. However, if this time is too short, the release implementation rate is low, and if it is too long, passengers' anxiety increases. The appropriate time interval is selected.

  If the emergency call release button 3 is not pressed within a predetermined time after the voice guidance unit 4 gives an instruction for an erroneous operation through the announcement by the speaker 18, the call transmission unit 5 calls the handset 7 of the monitoring center 33. This fixed time is measured by the timer 16 and is 5 to 10 seconds in this embodiment. That is, the monitoring center 33 confirms that the passenger pressing the emergency call button 2 is not an erroneous operation, and makes a call with the passenger to hear about an abnormal situation in the elevator car.

  By providing the emergency call release button 3 in addition to the emergency call button 2 in this way, the passenger who has accidentally pushed the emergency call button 2 does not have to excuse the staff of the monitoring center 33 and feels embarrassed. No need. For example, even if the child presses the emergency call button 2 by mistake with a button such as the car call button 19, the door open button 21 or the door close button 22, the parent immediately monitors the emergency call release button 3 to monitor. There is no need to make a call from the center 33. Even if the emergency call button 2 is depressed and the person is distracted or disturbed by a suspicious person, if the emergency call button 2 is pressed once, the telephone call with the monitoring center 33 is not performed unless the emergency call release button 3 is pressed. It becomes possible. In addition, the hearing impaired person cannot understand the operation method of the button depending on the announcement, but since the emergency call button 2 and the emergency call release button 3 can be visually confirmed, it is possible to prevent the report from being missed in an emergency. Furthermore, since the call can be omitted in the case of an emergency operation of the emergency call button 2 on the monitoring center 33 side, communication with passengers confined in the elevator car due to an abnormality or failure of the elevator, which is originally a business, and the elevator car You can concentrate on prevention of crimes that occur within 31 and rescue in the event of a disaster such as an earthquake.

  The emergency call button receiving unit 8 on the monitoring center 33 side receives the signal transmitted from the emergency call button transmitting unit 6 via the public communication line 32. The handset 7 receives a call from the call transmission unit 5 via the public communication line 32, and a call between the staff of the monitoring center 33 and the passenger becomes possible. Further, the emergency call button storage unit 10 stores a history of calls received by the receiver 7 and a history of emergency call button signals and emergency call button erroneous operation signals received by the emergency call button reception unit 8.

  The emergency call button management unit 9 calculates the frequency of occurrence of erroneous operation of the elevator from the number of emergency call button signals and emergency call button erroneous operation signals received for each elevator stored in the emergency call button storage unit 10 within a certain period. To do. The frequency of occurrence of the erroneous operation of the elevator is indicated, for example, by the number of receptions of the emergency call button erroneous operation signal with respect to the number of receptions of the emergency call button signal. Or you may calculate from the frequency | count of a telephone call with respect to the frequency | count of reception of an emergency call button signal. Further, the occurrence frequency of this erroneous operation may be calculated separately for the elevator car 31 during the daytime and at night. This is because an erroneous operation by a child is likely to occur in the daytime and an erroneous operation is likely to occur at night by a drunk person, so that a time zone in which an erroneous operation is likely to occur can be specified. Further, the emergency call button display unit 11 displays the number of receptions measured by the emergency call button management unit 9 or the calculated occurrence frequency for each elevator 31. When the emergency call button signal is transmitted, the emergency call button display unit 11 may display the occurrence rate of past erroneous operation or mischief operation of the elevator car 31 to the staff of the monitoring center 33. By this display, the staff of the monitoring center 33 can respond while grasping the actual usage of the emergency call button 2 of the elevator car 31 in the past.

  Next, a schematic configuration of another embodiment of the elevator call system will be described. In this embodiment, detection of mischievous operation is added to the above embodiment. As indicated by a broken line in the elevator car 31 of FIG. 1, the call system 1 of the elevator includes an in-car passenger detection means 12, a camera 14, or a sensor 15.

  As shown in FIG. 2, a camera 14 is installed on the ceiling of the elevator car 31. When the passenger presses the emergency call button 2, a picture in the elevator car 31 is taken by the camera 14 within a certain time. If no passenger is detected from the photographed photograph, an emergency call button mischief operation signal is transmitted to the emergency call button receiving unit 8 of the monitoring center 33. Moreover, the sensor 15 is installed in the wall surface in the elevator car 31. FIG. Then, when the passenger presses the emergency call button 2, the presence or absence of the passenger in the elevator car 31 is detected by the sensor 15 within a certain time. If no passenger is detected by the sensor 15, an emergency call button mischief operation signal is transmitted to the emergency call button receiving unit 8 of the monitoring center 33.

  A mischievous operation in the elevator car 31 can be detected by the passenger detection means 12 in the car. That is, when there are no other passengers in the elevator car 31, it is possible to avoid a call with the monitoring center 33 against the mischief of pressing the emergency call button 2 immediately before getting off the elevator. Moreover, even if it is not necessarily a mischief, as long as there are no passengers in the elevator car 31, the monitoring center 33 does not need to make a call. With this call system 1, the monitoring center 33 can concentrate on measures for rescue and safety of passengers in the elevator car 31.
