Description

  The present invention relates to an elevator control system that performs evacuation operation control for an elevator when a fire occurs in a building.

  In a conventional elevator control device, when a fire occurs in a building, the car is moved to the nearest floor and then moved to the evacuation floor. After this, the elevator is not allowed to operate and the car remains stopped on the evacuation floor. However, when a plurality of elevators are installed, if a plurality of cars return to the same evacuation floor at a time, the evacuation floor will be crowded by evacuated passengers. On the other hand, a method of shifting the return timing to the evacuation floor for each elevator group has been proposed (for example, see Patent Document 1).

  However, in the control method as described above, even for elevators that service a safe floor, the normal operation time is only slightly extended, and the elevators are not actively used as evacuation means. It takes time. On the other hand, in recent years, a method of using an elevator as an evacuation means has been proposed (for example, see Non-Patent Document 1).

Japanese Patent Laid-Open No. 5-8954 2004 Annual Meeting of the Fire Society of Japan (2004) pp. 590-593 “Study on the possibility of elevator evacuation in high-rise buildings (Part 2)”

  In the evacuation method using the conventional elevator as described above, it is conceivable that passengers concentrate on the elevator hall and a large number of passengers get into the arriving car at once. During normal operation, if the car's load is overloaded, it prompts you to get off by a buzzer or an announcement. There was a risk that evacuation efficiency would decline due to the delay in the start.

  This invention was made in order to solve the above subjects, and it aims at obtaining the elevator control system which can implement the evacuation using an elevator more efficiently at the time of a fire outbreak.

  The elevator control system according to the present invention performs an evacuation operation for evacuating a user by an elevator in the event of a fire, and when the load in the car is overloaded during the evacuation operation, Is equipped with an evacuation operation overload warning section that issues different warnings to passengers in the car.

  In the elevator control system of the present invention, when the load in the car is overloaded during the evacuation operation, a warning different from that in the normal operation is issued to the passengers in the car. This makes it possible for the passengers to quickly understand this, prevents a delay in the start of traveling of the car due to overload, and allows more efficient evacuation using the elevator.

The best mode for carrying out the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
1 is a block diagram showing an elevator control system according to Embodiment 1 of the present invention. There are several elevators installed in the building. The building is provided with a plurality of elevator group management devices 1. Each elevator group management device 1 manages a plurality of corresponding elevator control devices 2 as a group. Each elevator control device 2 controls the operation of the corresponding elevator car 3.

  A plurality of fire detectors 4 and a plurality of emergency broadcasting devices 5 are installed in the building. The emergency broadcast device 5 makes announcements regarding evacuation guidance in an emergency. A signal from the fire detector 4 is input to the disaster prevention management device 6. The disaster prevention management device 6 is installed in a disaster prevention center (monitoring room) in the building, and manages and manages the disaster prevention equipment of the entire building including the emergency broadcast device 5.

  An evacuation support device 7 is connected to the elevator group management device 1 and the disaster prevention management device 6. The evacuation support device 7 is installed, for example, in a disaster prevention center, and creates a plan of evacuation operation by an elevator when a fire occurs, and outputs an evacuation operation command based on the plan to the elevator group management device 1. In the evacuation operation, for example, the car 3 is reciprocated between a predetermined rescue floor and the evacuation floor.

  The elevator control device 2 includes communication means 8, operation control means 9, evacuation operation execution means 10, overload detection means 11, and overload warning means 12. The functions of these means 8 to 12 are realized by a microcomputer included in the elevator control device 2. That is, the microcomputer stores a program (software) for realizing the functions of the means 8 to 12.

  The communication means 8 communicates with the elevator group management device 1 and the like. The operation control means 9 controls the operation of the corresponding car 3 based on a command from the elevator group management device 1 during normal operation. The evacuation operation execution means 10 performs the evacuation operation of the corresponding car 3 based on the commands of the commands from the evacuation support device 7 and the elevator group management device 1 when a fire occurs.

  The overload detection means 11 detects that the load in the car 3 is in an overload state based on information from a scale device (not shown) or the like. When it is detected that the overload warning means 12 and the load in the car 3 are overloaded, a warning is given to the passengers in the car 3 to get out of the car.

  Specifically, when an overload is detected during normal operation, the overload warning unit 12 causes a warning device (not shown) provided in the car 3 to issue a warning by, for example, a buzzer sound or an announcement. Further, when an overload is detected during evacuation operation, the overload warning means 12 issues a warning different from that during normal operation to passengers in the car 3. In this example, as a warning different from that during normal operation, the flicker operation is performed after the lights in the car 3 are turned off. That is, in Embodiment 1, the elevator control device 2 functions as an evacuation operation overload warning unit.

  Next, the operation will be described. When the fire is confirmed by the disaster prevention management device 6, the information is input to the evacuation support device 7. Thereby, the evacuation assistance apparatus 7 outputs the instruction | command for implementing the control operation at the time of fire about all the elevators. In the fire control operation, all the cars 3 are returned to a predetermined return floor (for example, the nearest floor), the doors are opened, and the passengers get off.

  When the fire control operation ends, the evacuation support device 7 determines whether the evacuation operation can be started. If the start of evacuation operation is not possible, all elevators are left suspended. If the evacuation operation can be started, the evacuation operation is performed based on the evacuation operation plan.

  FIG. 2 is a flowchart showing the operation on the rescue floor during the evacuation operation of the elevator control device 2 of FIG. When the car 3 arrives at the rescue floor, the door is opened and the passenger is put on the car 3 (step S1). Then, it is determined whether or not an overload is detected (step S2). If no overload is detected, it is determined whether a predetermined time has elapsed since the door was opened (step S3). If the predetermined time has not elapsed, the process returns to overload determination (step S2).

  As described above, the elevator control device 2 monitors whether or not an overload is detected until a predetermined time elapses after the door is opened. And when predetermined time passes without overload being detected, the door is closed and the car 3 starts to travel (step S4).

  On the other hand, when an overload is detected while the door is open, first, a warning by a buzzer and announcement is issued for a predetermined time as in the normal operation (step S5). Thereafter, the elevator control device 2 determines whether or not the overload has been eliminated (step S6).

  When the overload is not eliminated by the buzzer and the announcement, the elevator control device 2 issues a warning by causing the flicker operation after turning off the illumination in the car 3 in addition to the warning by the buzzer and the announcement (step S7). Such a warning is continued until the overload is eliminated.

  When the overload is eliminated by the warning, the buzzer and the announcement are terminated, and the illumination in the car 3 is set to normal illumination (lighting) (step S8), and it is determined whether or not a predetermined time has elapsed since the door was opened. If the predetermined time has not elapsed, the process returns to overload determination (step S2), and if the predetermined time has elapsed, the door 3 is closed and the car 3 starts to travel (step S4).

  In such an elevator control system, if the load in the car 3 is overloaded during evacuation operation, a warning different from that during normal operation is issued to the passengers in the car 3, so even in a confused state when a fire occurs, It is possible to prompt the passenger to understand that it is a load, prevent a delay in the start of traveling of the car 3 due to an overload, and more efficiently carry out evacuation using an elevator.

In addition, if an overload is detected during evacuation operation, a warning is issued using a transmission method (transmission method using light) that is different from the transmission method used during normal operation (transmission method using sound). However, the passenger can be surely understood that it is overloaded.
Furthermore, if an overload is detected during the evacuation operation, the lighting state in the car 3 is changed and a warning is issued, so a visual warning is given to the entire car 3 using an existing lighting device. It can be communicated and the passenger can be understood more effectively that it is overloaded.
Furthermore, if an overload is detected during evacuation operation, a warning different from that during normal operation is issued in addition to the warning during normal operation. It is possible to make passengers understand more reliably.

Note that the overload warning method during evacuation operation is not limited to the above example, for example, a method of simply turning off the lighting in the car, or a warning sound such as a buzzer or announcement than during normal operation. It may be a method of flowing at a high volume, a method of flowing an announcement having a content different from that during normal operation, or the like.
In the above example, the evacuation operation overload warning unit is provided in the elevator control device 2, but the evacuation operation overload warning unit is not limited to this. For example, the evacuation operation overload warning unit is provided in the elevator group management device or the evacuation support device. May be. The evacuation operation overload warning unit may be a single independent device.
Furthermore, in the above example, if an overload is detected during evacuation operation, first a warning similar to that during normal operation is added and then a different warning is added. Only a warning different from that during normal operation may be given. Further, after giving a warning similar to that during normal operation for a predetermined time, it may be switched to a warning different from that during normal operation.
Furthermore, the evacuation operation method is not particularly limited, and is appropriately set according to the structure of the building and the installation situation of the elevator.

It is a block diagram which shows the elevator control system by Embodiment 1 of this invention. It is a flowchart which shows the operation | movement in the rescue floor in evacuation operation implementation of the elevator control apparatus of FIG.
