  When a fire or earthquake occurs, people left behind in the building may rush into the evacuation elevator. In such a case, for example, even in the device described in Patent Document 1, an overloaded state is detected, or the door closing operation is hindered, so that the operation of the elevator cannot be continued.

  When the elevator is used for evacuation, even if an overloading state is detected and a warning is issued, the passenger may not be able to get off because of danger such as fire. In such a case, there was a problem that the car was stopped on the floor where the fire occurred and time was passed, and passenger evacuation was delayed.

  The present invention has been made to solve the above-described problems. The purpose of the present invention is to ensure that even if a person left behind in a building rushes into an evacuation elevator when a disaster occurs, To provide an elevator control system that can avoid a panic situation and appropriately guide passengers to other evacuation routes.

  The elevator control system according to the present invention includes a disaster detection device that detects the occurrence of a predetermined disaster, and uses the elevator for evacuation when the occurrence of the disaster is detected by the disaster detection device. A control device for shifting to the evacuation mode, an information acquisition unit arranged on a predetermined evacuation route, a disaster prevention management device that determines whether or not the evacuation route can be used based on information acquired by the information acquisition unit, and an elevator An overload detection device that detects overloading of the car and a notification device provided at the car or elevator landing, and the control device continues for a predetermined time by the overload detection device after shifting to the disaster evacuation mode When the overloading of the car is detected, the information about the evacuation route determined to be usable by the disaster prevention management device is notified from the notification device. It is.

  With the elevator control system according to the present invention, even if a person left in the building rushes into an evacuation elevator at the time of a disaster, the passenger is prevented from panicking. It will be possible to properly guide to the evacuation route.

It is a block diagram which shows the control system of the elevator in Embodiment 1 of this invention. It is a flowchart which shows operation | movement of the control system of the elevator in Embodiment 1 of this invention.

  The present invention will be described in detail with reference to the accompanying drawings. In each drawing, the same or corresponding parts are denoted by the same reference numerals. The overlapping description is simplified or omitted as appropriate.

Embodiment 1 FIG.
1 is a block diagram showing an elevator control system according to Embodiment 1 of the present invention.

  In FIG. 1, reference numeral 1 denotes a disaster prevention management device provided in a building. This building is equipped with an elevator that can be used for evacuation in the event of a disaster such as a fire or earthquake. There may be one elevator or a plurality of elevators that can be used for evacuation. Further, an evacuation route through which a person in the building evacuates is set in advance in this building. The evacuation route includes a route using an elevator and a route not using an elevator. In an evacuation route that does not use an elevator, for example, an emergency staircase is included in the route.

In the building, a plurality of fire detectors 2 and a plurality of surveillance cameras 3 are installed.
The fire detector 2 is installed on each floor of a building, for example. The fire detector 2 is also installed on each evacuation route on each floor. When the fire detector 2 detects the occurrence of a fire, it transmits fire information to the disaster prevention management device 1. The fire information includes a signal indicating the occurrence of a fire, a signal indicating the location of the fire, and the like.

  The surveillance camera 3 is installed at, for example, a building entrance or an elevator hall. The surveillance camera 3 is also installed on each evacuation route on each floor. Information on the video imaged by the monitoring camera 3 is transmitted to the disaster prevention management device 1.

  A control device 4 controls the operation of the elevator. The evacuation route availability determination information providing unit shown in FIG. 1 includes a fire detector 2, a monitoring camera 3, and a control device 4.

  The disaster prevention management device 1 has a function of determining whether or not each evacuation route can be used (that is, whether or not the evacuation route can be used). The disaster prevention management device 1 makes this determination based on, for example, fire information from the fire detector 2 and video information from the monitoring camera 3. The disaster prevention management device 1 transmits the determination result to the control device 4.

  In the present embodiment, fire information from the fire detector 2 and video information from the monitoring camera 3 are used to determine whether the evacuation route can be used. However, this is just an example. By arranging other information acquisition means on each evacuation route, the disaster prevention management apparatus 1 may determine whether or not the evacuation route can be used based on the information acquired by the information acquisition means.

  The disaster prevention management device 1 also has a function of determining an operation mode to be performed now. The disaster prevention management device 1 makes this determination based on, for example, fire information from the fire detector 2 and video information from the monitoring camera 3. The disaster prevention management device 1 transmits a mode command based on the determination result to the control device 4. When receiving the mode command from the disaster prevention management device 1, the control device 4 performs switching (selection) of the operation mode based on the received mode command. When the control device 4 selects an operation mode suitable for the current situation, the control device 4 outputs a command corresponding to the operation mode to the operation control device 5, the door control device 6, the display control device 7, and the announcement control device 8. .

  For example, the control device 4 selects an optimum operation mode from the normal mode, the fire control mode, and the disaster evacuation mode based on the mode command received from the disaster prevention management device 1.

  The normal mode is a mode selected at the normal time. When the normal mode is selected by the control device 4, the operation control device 5 performs control to sequentially respond the car to calls registered at the landing or the car.

  The fire control mode is a mode selected when a fire occurs. When the fire control mode is selected by the control device 4, the operation control device 5 performs control for causing passengers in the car to get off at the evacuation floor. The evacuation floor is set in advance or appropriately selected according to the fire occurrence floor.

  The disaster evacuation mode is a mode selected when the elevator is used for evacuation. When the disaster evacuation mode is selected by the control device 4, the operation control device 5 performs control to put a person left in the building on the car and get off at the evacuation floor. For example, the operation control device 5 stops the car on the floor where the fire occurred or on the floor immediately above or directly below the floor where the fire occurred in order to rescue the people left in the building.

  The door control device 6 performs opening / closing control of the door of the elevator based on a command from the control device 4. The elevator door is provided with a reversing sensor unit 9 composed of a contact or non-contact sensor. The reversing sensor unit 9 outputs a reversing command for reversing the door during the door closing operation to the door control device 6. For example, the reversal sensor unit 9 outputs a reversal command to the door control device 6 when detecting that there is a passenger between the doors during the door closing operation. When the normal mode is selected by the control device 4, when the door control device 6 receives the reverse command from the reverse sensor unit 9, the door control device 6 reverses the door during the door closing operation to perform the door opening operation.

  The display control device 7 performs display control in the elevator. In the elevator, an in-car display 10 is installed in the car, and a landing display 11 is installed at each landing (or a predetermined landing). The display control device 7 controls display contents of the in-car display 10 and the hall display 11 based on a command from the control device 4.

  The announcement control device 8 performs announcement control in the elevator. In the elevator, an in-car announcement output unit 12 (for example, a speaker) is installed in a car, and a landing announcement output unit 13 (for example, a speaker) is installed at each landing (or a predetermined landing). The announcement control device 8 outputs an appropriate announcement from the in-car announcement output unit 12 or the hall announcement output unit 13 based on a command from the control device 4.

  The notification device shown in FIG. 1 includes an in-car display 10, a landing display 11, an in-car announcement output unit 12, and a landing announcement output unit 13. If information necessary for passengers in the elevator can be notified, it is not necessary to provide all the above devices as a notification device. Moreover, you may be provided with another apparatus as an alerting | reporting apparatus.

  The overload sensor unit 14 (overload detection device) detects an overload of the car. For example, the overload sensor unit 14 outputs an overload signal to the control device 4 when the load weight of the car exceeds the rating. When the control device 4 receives the overload signal from the overload sensor unit 14 when the normal mode is selected, the control device 4 outputs a predetermined command to the announcement control device 8 and sounds a buzzer sound or the like from the in-car announcement output unit 12. Let

  Next, the operation of the control system having the above configuration, particularly the operation when the disaster evacuation mode is selected, will be specifically described with reference to FIG. FIG. 2 is a flowchart showing the operation of the elevator control system according to Embodiment 1 of the present invention.

  The disaster prevention management device 1 receives predetermined damage information (for example, fire information from the fire detector 2 and predetermined video information from the monitoring camera 3) when the normal mode is selected by the control device 4 (S101). Yes), a mode command for switching to the disaster evacuation mode is output to the control device 4. Thereby, an elevator transfers to the disaster evacuation mode for rescuing the person left in the building (S102).

  If it transfers to evacuation mode at the time of a disaster, the operation control apparatus 5 will drive a car to a disaster floor (for example, fire occurrence floor), and will stop. When the car stops on the damaged floor, the door control device 6 opens the door of the elevator. Thereby, the passenger who was in the elevator hall of a damaged floor starts boarding (S103).

  In the disaster evacuation mode, the reverse function of the door by the reverse sensor unit 9 is disabled. For this reason, when the car stops at the damaged floor, basically, the door closing operation is forcibly started after a predetermined time has elapsed since the door was opened.

  When the car stops on the damaged floor, the control device 4 is guided to another evacuation means (evacuation route) that does not use the elevator (if there are multiple elevators for evacuation, the elevator stops on the damaged floor). It is determined whether or not it is necessary (S104). For example, when the disaster evacuation mode cannot be continued any more, the control device 4 determines that guidance to another evacuation means is necessary (Yes in S104). Whether or not the disaster evacuation mode can be continued is determined by whether or not a predetermined continuation condition is satisfied, for example. That is, the control device 4 determines that guidance to another evacuation means is necessary when the continuation condition is not satisfied.

  When the continuation condition is satisfied, the control device 4 determines that it is possible to continue the disaster evacuation mode and no guidance to other evacuation means is necessary (No in S104). Immediately after the car stops at the damaged floor, the above continuation condition is satisfied.

  If guidance to other evacuation means is not required, the control device 4 determines whether or not the car that is stopped on the damaged floor is in an overloaded state (S105). If the car is overloaded, an overload signal is transmitted from the overload sensor unit 14 to the control device 4. When the control device 4 receives the overload signal from the overload sensor unit 14 while the car is stopped on the damaged floor, the control device 4 causes the notification device to notify the user of getting off (S106).

  For example, the control device 4 outputs a predetermined command to the announcement control device 8 and announces contents such as “the elevator cannot be started due to full capacity” from the in-car announcement output unit 12 and the landing announcement output unit 13. The control device 4 may prompt the user to get off the vehicle by sounding a special buzzer from the in-car announcement output unit 12 or blinking / extinguishing an indicator light in the car. Alternatively, these notifications may be performed at the same time to prompt the user to get off.

  Next, the control device 4 determines whether or not the door closing is completed and the elevator (car) is in a state where it can leave the damaged floor (S107). If an overload state is not detected in S105, a door closing operation is performed after a predetermined time has elapsed since the car arrived at the damaged floor. When the door closing is completed, a signal to that effect is transmitted from the door control device 6 to the control device 4 (Yes in S107). When the control device 4 receives a signal indicating the door closing completion from the door control device 6, the control device 4 outputs a predetermined command to the operation control device 5 and departs the car toward the evacuation floor (S108). The evacuation floor is set in advance or appropriately selected according to the damaged floor (fire occurrence floor).

  On the other hand, if an overloading state is detected in S105, the door closing operation is not started, and a signal indicating door closing completion is not output from the door control device 6 (No in S107). In such a case, the control device 4 returns to the process of S104 and determines again whether or not guidance to another evacuation means that does not use the elevator is necessary. In the continuation condition, the continuation time of the overload state is considered. For example, if the overloading state has not continued for a predetermined time or longer, the continuation condition is satisfied. In such a case, the control device 4 determines that it is possible to continue the disaster evacuation mode and that guidance to other evacuation means is not necessary (No in S104).

  On the other hand, when the person left behind in the building rushes to the evacuation elevator or the like, and the overload state continues for a predetermined time or more after the transition to the disaster evacuation mode, the control device 4 continues the disaster evacuation mode. Therefore, it is determined that guidance to another evacuation means is necessary (Yes in S104). In other words, after the car is stopped on the damaged floor, if the overload sensor unit 14 continuously detects the overload of the car for a predetermined time, the continuation condition is not satisfied.

  In such a case, the controller 4 terminates the disaster evacuation mode (that is, use of the elevator) and information for guiding passengers in the car and landing to other evacuation routes (evacuation means), The notification device notifies the user (S109). For example, the above information is displayed on the in-car display 10 and the hall display 11. Further, the above information is announced from the in-car announcement output unit 12 and the hall announcement output unit 13. Thereafter, the disaster evacuation mode is terminated and the use of the elevator is stopped (S110).

  The disaster prevention management device 1 determines whether or not each preset evacuation route can be used based on the fire information from the fire detector 2 and the video information from the monitoring camera 3. The fire detector 2 and the monitoring camera 3 are arranged along each evacuation route so that the disaster prevention management apparatus 1 can make the above determination. Based on the determination result of the disaster prevention management device 1, the control device 4 causes the notification device to notify the information of the evacuation route determined to be usable by the disaster prevention management device 1. The determination as to whether or not each evacuation route can be used by the disaster prevention management apparatus 1 may be started when the continuation condition is not satisfied and a determination of Yes is made in S104.

  When there is another elevator that can be safely used for evacuation in the building, the control device 4 informs the information about the route to the elevator landing from the notification device as evacuation route information. Further, when there is no other elevator that can be safely used for evacuation, the control device 4 notifies the information on the route including the emergency stairs from the notification device as the evacuation route information if the emergency stairs can be safely used. Let When there are a plurality of routes for evacuating safely from the elevator landing on the damaged floor, the control device 4 causes the notification device to notify the information on the routes that can be evacuated safely and in a short time among the evacuation routes as evacuation route information. .

  In order to appropriately determine alternative routes, the distance between each evacuation route (for example, the distance from the elevator landing to the other evacuation route) and the time required for evacuation by each evacuation route (evacuation time) Or the like may be registered in the disaster prevention management apparatus 1 in advance.

  In addition, when the number of passengers to be guided to other evacuation routes can be grasped, out of the evacuation routes determined to be usable by the disaster prevention management device 1, information on routes that can be evacuated by all passengers at the same time, You may make it alert | report from a notification apparatus preferentially as evacuation route information. In such a case, a means (passenger detection means) for detecting the number of passengers in the hall or the car (that is, passengers who can no longer evacuate from the hall using an elevator) is required. As the passenger detection means, for example, the monitoring camera 3 may be used, and the number of passengers may be detected from the video imaged by the monitoring camera 3. When the passenger has an ID recording medium, the number of passengers may be detected by acquiring personal information from the ID recording medium.

  With the control system having the above configuration, when the elevator is used for evacuation, it is possible to appropriately determine whether or not the disaster evacuation mode is continued and terminated. For this reason, even if a person left in the building rushes into an evacuation elevator when a disaster occurs, it is possible to prevent the passenger from falling into a panic state, and to make the passenger suitable for another evacuation route. Can be guided to.

  In the present embodiment, a specific description has been given of the case of shifting to the disaster evacuation mode based on the fire information from the fire detector 2. When another disaster detection device (for example, an earthquake detector) is installed in the building, the control device 4 causes the elevator to operate in a disaster (earthquake) control mode when the disaster detection device detects the occurrence of a predetermined disaster. , Shift to evacuation mode in disaster. And the operation | movement shown in FIG. 2 is implemented at the time of disaster evacuation mode.
