Description

  Embodiments of the present invention relate to a system and method for controlling a notification device provided at an elevator hall in the event of an emergency such as a fire.

  Residents are instructed to evacuate by stairs, not elevators or escalators, when a fire breaks out in an office building or shopping center. In fact, not only in Japan but also overseas, we often see cautions not to use elevators in elevators and elevator halls, but to use stairs in the event of a fire. However, in the past fires, it is also true that there are not a few cases of evacuation using elevators, especially in the early days of fire. On the other hand, the proportion of elderly people is rapidly increasing in developed countries, especially in Japan. This makes it possible to predict that the number of people who have difficulty using stairs during an emergency evacuation such as a fire in a building will increase year by year. Although there has been a potential demand for using an elevator for evacuation in the past, with the progress of aging and becoming barrier-free, in recent years, it has begun to be spoken gradually as an obvious demand. In particular, since the collapse of the World Trade Center Building on September 11, 2001, due to a plane collision, even in the United States, even if it was a skyscraper, there was a need for a smooth evacuation of the entire building, not just the conventional partial evacuation near the fire floor. Coupled with this momentum, there is a growing debate about the emergency use of elevators in the United States.

  In Japan, in the “Regulatory Reform Promotion Three-Year Plan” in March 2003, “Standby areas around elevators to ensure safe and prompt evacuation in the event of disasters such as disabled persons such as wheelchair users and the elderly. "We will consider the use of elevators as a means of evacuation for persons with physical disabilities, elderly people, etc., considering the safety of elevators, etc."

  Against this background, in recent years, it has been considered to provide an elevator system that can promptly evacuate the residents to the evacuation floor by actively using the elevator when a disaster such as a fire occurs. ing.

  When a fire breaks out, the elevator hall's visibility deteriorates due to a large amount of smoke or power outage that fills the building, so even if there are people in the vicinity of the elevator hall trying to evacuate using the elevator, There may be situations where it is difficult to find an elevator hall indicator or hall call registration button device. In this case, since the evacuation time of the residents increases, there is a problem that the risk of the residents increases.

  In Patent Document 1, for the purpose of improving the visibility of the hall indicator, a timer is provided in the hall indicator to detect the elevator operating time, and the elevator operating time and the display element of the hall indicator are deteriorated over time. A technique for automatically correcting the brightness of characters displayed on the hall indicator by calculating the brightness of the current display character from the brightness change and changing the driving pulse width of the hall indicator based on the calculation result is disclosed. . According to this prior art, although it is possible to automatically correct the luminance change due to the aging deterioration of the display element according to the operating time of the hall indicator, the hall indicator according to the change in the surrounding situation (visibility) of the hall The brightness adjustment was not taken into consideration at all, and there was a problem that no measures were taken regarding the brightness adjustment of the hall indicator in an emergency such as a situation where the smoke at the time of fire was full.

The hall illuminance sensors 7a, 7b and 7c detect, for example, the illuminance of the area including the corresponding hall doors 4a, 4b and 4c. The hall illuminance sensors 7a, 7b, and 7c are connected to the control unit 1 via the hall illuminance data transmission channels 8a, 8b, and 8c, respectively. To communicate. As will be described later, the control unit 1 has a function of controlling the hall indicators 5a, 5b and 5c in accordance with the received hall illuminance data. A fire detector 9 that detects the occurrence of a fire in the building and issues a fire detection signal when the occurrence of the fire is detected is provided at an appropriate location of the building where the elevator is installed. Is connected to the control unit 1 via the fire detection signal transmission channel 10. When the control unit 1 receives the fire detection signal from the fire detector 9, the control unit 1 switches the elevator from the normal operation mode to the evacuation operation mode, and responds according to the landing illuminance data received from the landing illuminance sensors 7a, 7b, and 7c. The display brightness of the hall indicators 5a, 5b and 5c of the hall to be controlled is controlled. For example, the control unit 1 collates illuminance data representing the illuminance of each hall received from the hall illuminance sensors 7a, 7b, and 7c with reference luminance data stored in the control unit 1. Based on the comparison result, the control unit 1 transmits the hall indicator luminance data representing the appropriate luminance for the hall indicators 5a, 5b and 5c via the hall indicator data transmission channels 6a, 6b and 6c, respectively.

The control unit 1 treats the illuminance data received from the landing illuminance sensors 7a, 7b and 7c as valid only during operation in the evacuation operation mode.

  The landing illuminance sensors 7a, 7b, and 7c may be always operated. However, in one actual embodiment, while the control unit 1 is operating in the evacuation operation mode, the control unit 1 detects the landing illuminance sensors 7a, 7b. And 7c are operated.

  In another embodiment, the control unit 1 further displays a guidance display according to the illuminance data representing the illuminance of each landing received from the landing illuminance sensors 7a, 7b, and 7c. , And control to display on the respective hall indicators 5a, 5b and 5c.

  Next to the landing floors of the elevator cars 2, usually next to the landing doors 4a, 4b and 4c, landing call registration buttons 11a, 11b and 11c for accepting registration of landing calls are provided. These hall call registration buttons 11a, 11b, and 11c are connected to the control unit 1 via hall call registration transmission channels 12a, 12b, and 12c, respectively, and the hall call registration buttons 11a, 11b, and 11c are operated by the residents. When pressed, the pressed signal is transmitted to the control unit 1 via the corresponding hall call registration transmission channels 12a, 12b and 12c. The hall call registration buttons 11a, 11b, and 11c include hall call registration button lights 13a, 13b, and 13c, respectively, indicating that the hall call registration buttons 11a, 11b, and 11c are pressed. In another embodiment, the hall call registration button lights 13a, 13b and 13c are connected to the control unit 1 via hall call registration button lamp luminance transmission channels 14a, 14b and 14c, respectively. While operating in the evacuation operation mode, the control unit 1 further displays the display brightness of the corresponding hall call registration button lights 13a, 13b, and 13c according to the hall illumination data received from the hall illumination sensors 7a, 7b, and 7c, respectively. Is transmitted to the corresponding hall call registration button lights, and the display brightness of each of the hall call registration button lights 13a, 13b and 13c is controlled.

  In another embodiment, the controller 1 further presses the hall call registration button when the hall illuminance corresponding to the transmitted hall illuminance data is equal to or less than a predetermined value during operation in the evacuation operation mode. At least one of the hall indicator (5a, 5b or 5c) and the hall call registration button light (13a, 13b or 13c) of the hall which has not been made is blinked.

  In a further embodiment, the control unit 1 causes the hall indicators 5a, 5b, and 5c to display predetermined contents according to the received hall illuminance data during operation in the evacuation operation mode.

  In still another embodiment, hall audio devices 15a, 15b, and 15c that output audio announcements are provided around the hall doors 4a, 4b, and 4c of the halls, respectively. The hall audio devices 15a, 15b and 15c are connected to the control unit 1 via hall announcement data transmission channels 16a, 16b and 16c, respectively. While operating in the evacuation operation mode, the control unit 1 transmits voice announcement data corresponding to a predetermined voice announcement to the hall voice devices 15a, 15b, and 15c according to the received hall illuminance data. Announcement is output.

  Although various transmission channels are shown in FIG. 1, these are logical transmission channels, and can be physically implemented by a single bus-like transmission line.

  In FIG. 2, the functional block diagram for demonstrating the control part 1 in one Embodiment is shown. In FIG. 2, the functional components already shown in FIG. 1 are also shown in order to explain the function of the control unit 1, but these functional components are denoted by the same reference numerals in FIG. The description is omitted. The control unit 1 is usually implemented by a so-called embedded system including hardware resources such as a microcomputer, ROM, RAM, or magnetic storage device, and software necessary for elevator control. The control unit 1 can also be implemented by hardware.

  The control unit 1 includes an operation mode switching control unit 21, a display control unit 22, and a luminance data storage unit 23. A fire detector 9 is connected to the operation mode switching control unit 21 via the fire detection signal transmission channel 10. When a fire detection signal is output from the fire detector 9 and is input to the operation mode switching control unit 21, the operation mode switching control unit 21 switches the elevator from the normal operation mode to the evacuation operation mode. In addition, a display control unit 22 is connected to the operation mode switching control unit 21 via an operation switching signal transmission channel 24. In one embodiment, when the operation mode switching signal is received from the operation mode switching control unit 21, the display control unit 22 uses the landing illuminance data transmission channels 8a, 8b, and 8c to enter the landing illuminance sensors 7a, 7b and 7c are activated. The hall illuminance sensors 7a, 7b and 7c may be always operated. The display control unit 22 is further connected to the luminance data storage unit 23 via the luminance storage data transmission channel 25. In the luminance data storage unit 23, luminance data representing the luminance of the hall indicators 5a, 5b and 5c, or the hall indicators 5a, 5b and 5c and the hall call registration button lights 13a, 13b and 13c, which are appropriate for the hall illuminance data. Both luminance data are stored. The display control unit 22 is also connected to the landing indicators 5a, 5b and 5c via the landing indicator data transmission channels 6a, 6b and 6c, respectively. The display control unit 22 is connected to the hall call registration button lights 13a, 13b, and 13c via hall call registration button lamp luminance transmission channels 14a, 14b, and 14c, respectively.

When the fire detection signal output from the fire detector 9 is input to the operation mode switching control unit 21 and the display control unit 22 receives the operation mode switching signal output from the operation mode switching control unit 21, the display control unit 22 The luminance data of the hall indicators 5a, 5b and 5c appropriate for the hall illuminance data received from the hall illuminance sensors 7a, 7b and 7c are read from the luminance data storage unit 23, and the read luminance data are Communicate to the indicators 5a, 5b and 5c. Table 1 shows an example of the reference luminance which is the luminance of the hall indicator corresponding to the luminance data stored in advance in the luminance data storage unit 23 and associated with the hall illuminance data.

  The reference luminance is appropriately set according to the landing illuminance detected by the landing illuminance sensors 7a, 7b, and 7c, and is stored in the luminance data storage unit 23. The display control unit 22 operates in the evacuation operation mode so that the hall indicators 5a, 5b, and 5b are displayed with reference luminance corresponding to the hall illuminance received from the hall illuminance sensors 7a, 7b, and 7c, or luminance higher than the reference luminance. An instruction is transmitted to 5c. For example, when the illuminance detected by the third floor hall illuminance sensor is 1200 lux, the display controller 22 changes the third floor hall indicator so that the third floor hall indicator is displayed with a luminance of 500 candela or higher. Communicate instructions. Table 1 shows an example of a correspondence relationship between the hall illuminance and the base brightness of the hall indicator, and different reference brightness can be set. Furthermore, the appropriate reference luminance value varies depending on the installation position of the hall illuminance sensors 7a, 7b and 7c, the output directivity of the hall indicators 5a, 5b and 5c, the color of the wall surface of the hall, etc. The appropriate reference luminance data corresponding to the hall is set and stored in the luminance data storage unit 23 in advance.

  By appropriately controlling the brightness of the hall indicator in this way, even if the elevator hall becomes dark due to smoke caused by fire, the visibility of the hall indicator is constant for those who evacuate using the elevator. It can be secured within the range of the above, and safer and quicker evacuation can be promoted.

  In another embodiment, the display control unit 22 is operating in the evacuation operation mode, and the hall call registration button lights 13a, 13b, and 13c that are appropriate for the hall illuminance data received from the hall illuminance sensors 7a, 7b, and 7c. Is selected based on the data stored in the luminance data storage unit 23, and the selected luminance data is transmitted to the hall call registration button lights 13a, 13b and 13c. The reference luminance corresponding to the luminance data related to the hall call registration button light, which is appropriate for the hall illumination data, is the same as the reference luminance corresponding to the luminance data related to the hall indicator shown in Table 1, and is related to the hall call registration button light. It may be the same as or different from the reference luminance. The reference luminance relating to the hall call registration button light appropriate for the hall illuminance is set to be the same as the reference luminance relating to the hall indicator, stored in the luminance data storage unit 23, and detected by the hall illumination intensity sensor 7 on the second floor. When the illuminance is 80 lux, the display control unit 22 transmits an instruction to set the display brightness to 2000 candela or higher to the hall call button lamp on the second floor. As described above with respect to the reference luminance of the hall indicator, the appropriate reference luminance value is determined by the installation position of the hall illuminance sensors 7a, 7b and 7c, and the output direction of the light emitting elements used for the hall call button lights 13a, 13b and 13c. Therefore, appropriate reference luminance data corresponding to the property where the elevator is installed and the hall is set and stored in the luminance data storage unit 23 in advance.

  By appropriately controlling the brightness of the hall call registration button light in this way, the hall call registration button for those who evacuate using the elevator even if the elevator hall becomes dark due to smoke or the like caused by fire The visibility of the lamp is ensured within a certain range, and safer and quicker evacuation can be promoted.

  The control unit 1 also includes a hall call registration control unit 26, which is connected to the hall call registration buttons 11a, 11b and 11c via the hall call registration transmission channels 12a, 12b and 12c. Yes. The hall call registration control unit 26 is also connected to the display control unit 22 via a hall call registration data transmission channel 27. The hall call information registered by the hall call registration buttons 11a, 11b, and 11c installed at each hall is transmitted from the hall call registration control unit 26 to the display control unit 22 as hall call registration data for each hall. Based on the presence / absence of the hall call registration of each hall transmitted from the hall call registration control section 26 during the operation in the evacuation operation mode, the display controller 22 is a hall with no hall call registration and the hall illumination is determined in advance. From the display control unit 22, the hall indicators 5a, 5b, and 5c receive control signals for instructing at least one of the hall landing indicators 5a, 5b, and 5c and the hall call registration button lights 13a, 13b, and 13c to be flashing. And the hall call registration button lights 13a, 13b, and 13c.

  In this way, when the hall has a certain level of illuminance, the visibility can be improved by blinking the hall indicator or the hall call button.

In another embodiment, the control unit 1 further includes a hall message data storage unit 28. In the hall message data storage unit 28, hall message data representing a hall message corresponding to the hall illuminance is stored in advance. The display control unit 22 stores the hall message data corresponding to the hall illuminance data received from the hall illuminance sensors 7a, 7b and 7c during the operation in the evacuation operation mode via the hall message data transmission channel 29. The hall message data read from the unit 28 and transmitted to the hall indicators 5a, 5b and 5c, respectively. The hall indicators 5a, 5b, and 5c display message contents corresponding to the received hall message data at the respective halls by a display unit such as a liquid crystal display mounted on each hall indicator. Table 2 shows an example of display contents corresponding to the hall message data stored in advance in the hall message data storage unit 28 and associated with the hall illuminance data.

  The display content is appropriately set according to the hall illuminance detected by the hall illuminance sensors 7a, 7b and 7c, and is stored in the hall message data storage unit 28. The display control unit 22 displays the display message content corresponding to the landing message suitable for the landing illuminance received from the landing illuminance sensors 7a, 7b and 7c during operation in the evacuation operation mode, so that the landing indicators 5a, 5b and 5c are displayed. Communicate instructions to In accordance with the transmitted instruction, each of the hall indicators 5a, 5b and 5c displays the message content via a display unit such as an installed liquid crystal display. For example, when the illuminance detected by the second floor hall illuminance sensor 7 is 500 lux, it is considered that sufficient illuminance is still secured for evacuation at the second floor hall, so the elevator is evacuating. An instruction is transmitted to the landing indicators 5a, 5b and 5c so as to display a display message (display contents) to that effect on a display such as a liquid crystal display mounted on the landing indicators 5a, 5b and 5c. Table 2 shows an example of the correspondence between the hall illuminance and the display contents, and different display contents can be set. In addition, the value and display contents of the hall illuminance vary depending on the installation position of the hall illuminance sensors 7a, 7b and 7c, the color of the hall wall, the shape and size of the hall, and so on, depending on the property where the elevator is installed and the hall Appropriate data is set and stored in the hall message data storage unit 28 in advance. Further, in different embodiments, a rotating lamp or the like can be used instead of displaying the display message on the hall indicator.

  By appropriately controlling the display content of the hall indicator in this way, appropriate information can be given to the evacuated residents, and safer and quicker evacuation can be promoted.

  In yet another embodiment, the control unit 1 includes a voice announcement control unit 30 and a voice announcement data storage unit 31. The voice announcement control unit 30 receives illuminance data for each landing from the display control unit 22 via the landing illuminance data transmission channel 32. The voice announcement control unit 30 corresponds to the illuminance data for each hall received from the display control unit 22 during operation in the evacuation operation mode, and the voice announcement data stored in advance in the voice announcement data storage unit 31 is converted into voice data. The read voice announcement data is transmitted to the hall voice devices 15a, 15b, and 15c via the transmission channel 33, respectively. The hall audio devices 15a, 15b and 15c that have received the voice announcement data respectively output the voice announcement contents corresponding to the received voice announcement data to the respective halls. When the correspondence between the hall illuminance and the content of the voice announcement is the same as shown in Table 2, for example, when the illuminance detected by the hall illuminance sensor 7 on the 3rd floor is 50 lux, the hall on the 3rd floor is caused by fire smoke Because it is considered that it is quite difficult to evacuate people in the hall, voice announcement data representing voice announcements that guide people to reach the elevator hall safely and quickly This is transmitted to the audio device 15. Table 2 shows an example of a correspondence relationship between the hall illuminance and the voice announcement contents. The values of the hall illuminance and the voice announcement contents are the installation positions of the hall illuminance sensors 7a, 7b and 7c, and the wall surface of the hall. Since it differs depending on the color, the shape and area of the hall, etc., appropriate data corresponding to the property where the elevator is installed and the hall is set and stored in the voice announcement data storage unit 31 in advance. The voice announcement content and the display message content may be different words. Furthermore, a sound such as a buzzer or a siren may be used instead of the voice announcement.

  By appropriately controlling the notification using sound in this way, it is possible to notify the visually impaired people of the location of the landing or the situation in the building, and to promote safer and quicker evacuation.

  Next, operations in the above-described embodiment will be described with reference to a flowchart. FIG. 3 shows a flowchart of the entire processing procedure in the embodiment. First, in step S302, it is determined whether or not a fire detection signal is received from the fire detector 9 to the control unit 1. The control unit 1 constantly monitors whether or not a fire detection signal has been received. If it is determined in step S302 that a fire detection signal has been received, the operation mode switching control unit 21 switches the operation mode from the normal operation mode to the evacuation operation mode in step S304. In step S <b> 306, the display control unit 22 receives an operation mode switching signal indicating that the operation mode has been switched from the normal operation mode to the evacuation operation mode from the operation mode switching control unit 21.

  When the display control unit 22 receives the operation mode switching signal, for example, as shown in steps S308 to S316, the display control unit 22 performs the following processing on the landings of all the landing floors (total number: N) of the building. Here, a positive number of 1 to N is assigned to each landing floor. In step S308, the number n of the first landing floor to be processed is set to 1 (for example, the lowest floor). Next, in step S310, hall illuminance detection processing for the nth floor, which will be described later with reference to FIG. 4, is performed. Next, in step S312, a hall notification control process for the nth floor, which will be described in detail later with reference to FIG. 5, is performed. When the landing notification control process is completed, the process proceeds to step S314, where the number n of the landing floor is incremented in order to perform processing for another landing floor, and whether or not n exceeds the total number N of landing floors in step S316. Judging. If n does not exceed N, that is, if the processing relating to all landing floors has not yet been completed, the processing returns to S310 and the above-described processing is repeated for all landing floors. If it is determined in step S316 that n is greater than N, the process returns to step S302 because processing for all landing floors has been completed.

  If it is determined in step S302 that the fire detection signal has not been received, the process proceeds to step S318, and the normal operation mode is continued.

  FIG. 4 is a flowchart showing the landing illuminance detection process in the evacuation operation mode shown in FIG. The flowchart shown in FIG. 4 shows the processing procedure in step S310 of the flowchart shown in FIG. When the display control unit 22 receives the operation mode switching signal from the operation mode switching control unit 21, in one embodiment, in step S402, the display control unit 22 outputs an activation signal to the landing illuminance sensors 7a, 7b, and 7c provided for each landing. . As described above, when the hall illuminance sensor is always operated, step S402 is skipped. Next, in step S404, the hall illuminance sensors 7a, 7b, and 7c detect illuminance data of the corresponding halls, and transmit the detected illuminance data to the display control unit 22.

  FIG. 5 is a flowchart showing the hall notification control process in the evacuation operation mode shown in FIG. The flowchart shown in FIG. 5 shows the processing procedure in step S312 of the flowchart shown in FIG. 3 in detail. In step S <b> 502, the display control unit 22 receives illuminance data on the n-th floor from the n-level hall illuminance sensor 7. Next, in step S504, the display control unit 22 converts the received illuminance data of the nth floor based on the correspondence relationship between the hall illuminance stored in the luminance data storage unit 23 and the reference luminance shown in Table 1, for example. The n-th floor reference luminance corresponding to the illuminance data of the hall is specified.

  Next, the display control unit 22 compares the reference luminance specified in step S504 with the current luminance setting value of the n-floor hall indicator 5, and determines whether or not the current setting value is brighter than the reference luminance. The determination is made in step S506. If the current set value is brighter than the reference luminance, the process proceeds to step S514 described later. In one embodiment, the display control unit 22 also compares the reference luminance specified in step S504 with the current setting value of the current luminance of the hall call registration button lamp 13 of the n-th floor hall, and the current setting value is the reference value. Whether it is brighter than the brightness is also determined in step S506. If the current set value is brighter than the reference luminance, the process proceeds to step S514 described later.

  If it is determined in step S506 that the current brightness setting value of the n-th hall landing indicator 5 is darker than the reference brightness specified in step S504, in step S508, the display control unit 22 sets the current brightness setting value. Is transmitted to the hall indicator 5 of the nth floor hall to change the brightness to the specified reference brightness value. In one embodiment, if it is determined that the current brightness setting value of the nth floor hall call registration button lamp 13 is darker than the reference brightness specified in step S504, the display control unit 22 further determines the nth floor hall. A brightness change instruction for changing the current brightness setting value of the hall call registration button lamp 13 to the specified reference brightness value is transmitted to the hall call registration button lamp 13 of the nth floor hall.

  Subsequently, in step S510, the hall call registration control unit 26 determines whether the hall call registration button 11 for the n-th floor hall has already been pressed, that is, whether or not a call has been registered. If it is determined in step S510 that the hall call registration button 11 for the n-th floor has already been pressed, the process proceeds to step S514.

  In step S510, if the hall call registration control unit 26 determines that the nth floor hall call registration button 11 has not been pressed, the hall call registration control unit 26 notifies the display control unit 22 accordingly. To do. The display control unit 22 that has received the notification blinks at least one of the n-th floor hall indicator 5 and the hall call registration button lamp 13 in step S512. Thereafter, the process proceeds to step S514.

  In step S514, the display control unit 22 collates the received illuminance data of the nth floor with the correspondence table shown in Table 2 stored in the hall message data storage unit 28, for example. In accordance with the collation result, the display control unit 22 transmits an instruction to display the display content corresponding to the received illuminance data on the n-th floor hall indicator 5.
