Japanese Patent Laid-Open No. 11-11812 (first page, FIG. 1)

  However, when a fire shutter or a fire shutter with an exit is installed before landing on the evacuation floor, there are the following disadvantages. That is, when the elevator control device guides the passenger in front of the fire shutter that is already closed, the passenger cannot be evacuated smoothly by the fire shutter. In addition, even when the elevator controller closed the door after the passenger opened the exit door of the fire shutter and closed the door, the passenger could not be evacuated smoothly by closing the door. .

  The present invention has been made in order to avoid the above-described inconveniences, and an object thereof is to obtain an elevator control device capable of smoothly evacuating passengers during a fire control operation.

The elevator control device according to the present invention includes a fire shutter installed before landing on the evacuation floor when the car is provided with car operation control means for stopping the car on the evacuation floor and controlling the opening and closing of the car door during fire control operation. Information storage means for storing presence / absence and presence / absence of the exit of the fire shutter is further provided, and the car operation control means performs the following processing. That is, the car operation control means refers to the information storage means for storing the presence / absence of a fire shutter installed before the landing of the evacuation floor and the presence / absence of the exit of the fire shutter, and fire prevention is performed on the evacuation floor where the car is stopped If it is determined that a shutter is installed and the fire shutter installed before landing on the evacuation floor is closed, it is determined whether there is an exit, and if there is no exit, the car that is stopped on the evacuation floor the door-closing allowed to continue, when the escape hatch is present, then the door open, until there is an opening operation and a series of operations of the closing operation of the door of the escape hatch, Ru to continue the door open of the car that is stopped at the evacuation floor .

  Since the elevator control device of the present invention controls the opening and closing of the door according to the opening and closing of a fire shutter installed before landing on the evacuation floor, passengers in the car can be evacuated smoothly.

Hereinafter, the elevator control apparatus according to Embodiments 1 and 2 will be described. Here, the case where the elevator control device 10 is installed in the following building facility will be described as an example. A plurality of stop floors and evacuation floors are provided in the building facility. And before the landing of a specific evacuation floor, a fire shutter or a fire shutter with an exit is installed based on the disaster prevention plan.
Embodiment 1 FIG.
FIG. 1 is a configuration diagram illustrating an elevator control apparatus according to Embodiment 1 of the present invention.

  In FIG. 1, the elevator control device 10 is connected to a fire shutter device 20a and a fire shutter device 20b with exit. The fire shutter device 20a controls the fire shutter installed before landing on the evacuation floor, and the exit fire prevention shutter 20b controls the fire shutter with escape port installed before landing on the evacuation floor. is there. The elevator control device 10 is connected to the encoder device 30 and the floor detection switch 40. The encoder device 30 outputs the rotational speed of a hoisting machine (not shown), and is used for detecting a car position. The floor detection switch 40 outputs a stop floor signal indicating the stop floor of the car, and is provided on each stop floor. Furthermore, the elevator control device 10 is connected to a car door device 50 that opens and closes a stopped car door. A car interphone (emergency call device) 60 and an external interphone 70 are connected to the elevator control device 10 via a call line 80. The external intercom 70 is installed in a monitoring center or a manager room.

  The elevator control device 10 will be described in detail. In FIG. 1, the elevator control device 10 includes a fire shutter opening / closing state detecting means 11, an exit / exit opening / closing state detecting means 12, a car position detecting means 13, a car operation control means 14, and a telephone line automatic connection means 15. Each of these means 11, 12, 13, 14, 15 is a CPU, for example, and their functions will be described later (see FIG. 2). Further, the elevator control means 10 has information storage means 16. The information storage means 16 is for storing information, for example, a memory.

  The information storage means 16 stores normal operation time information and fire control operation time information. The normal driving time information relates to driving during normal driving, and includes information such as car calls and landing calls, for example. The information at the time of fire control operation relates to the operation at the time of fire control. This fire control operation time information includes the presence / absence of a fire shutter installed before landing on the evacuation floor, and the presence / absence of exit of the fire shutter (presence / absence of fire shutter with exit).

Next, the operation of the elevator control device 10 will be described with reference to FIG.
FIG. 2 is a flowchart showing the operation of the elevator control device 10. Here, as an example, the elevator control device 10 switches the operation mode from normal operation to fire control operation due to the occurrence of a fire, and stops the car on a safe evacuation floor according to the fire occurrence situation such as a fire floor. explain.

  The car operation control means 14 controls the operation of the car in the normal operation unless a fire signal is input from a fire receiver (not shown) (S101, S102). During normal operation, the car position detection means 13 detects the car position based on the number of rotations of the hoisting machine from the encoder device 30 and the stop floor signal from the floor detection switch 40. When the fire signal is not input from the fire receiver (S102), the car operation control means 14 continues to control the car operation in the normal operation based on the detection result of the car position detection means 13 (S101).

  When the car operation control means 14 inputs a fire signal from the fire receiver during normal operation (S102), the car operation control means 14 switches the operation mode to fire control operation and calls the car stored in the information storage means 16. The hall call is canceled and the car is called back to the evacuation floor (for example, the first floor) (S103). Then the car returns to the evacuation floor.

  Next, the car operation control means 14 refers to the information storage means 16 to determine whether or not a fire shutter is installed before landing on the evacuation floor where the car is stopped, and the fire shutter is installed. (S104), the process proceeds to the next S105.

  In S105, the fire shutter open / close state detection means 11 receives a fire shutter open signal or a close signal (hereinafter referred to as “open / close signal”) from the fire shutter device 20a, and the fire shutter open / close state based on the open / close signal. Is detected. When the fire shutter open / close state detection means 11 detects the fire shutter open state, the process proceeds to S106. If it is determined in S104 that the fire shutter is not installed, the process proceeds to S106.

  In S <b> 106, the car operation control means 14 drives the car door device 50 to open the door. Then, the car operation control means 14 changes the car door device 50 after a predetermined door opening waiting time (which means a time for opening the door and waiting on the evacuation floor) has elapsed (for example, after 15 seconds). The door is driven to close (S107), and then the elevator is stopped (S108).

  On the other hand, when the fire shutter open / close state detection means 11 detects the fire shutter closed state in S105, the process proceeds to the next S109.

  In S <b> 109, the call line automatic connection unit 15 automatically connects the in-car interphone 60 and the external interphone 70 to the call line 80. Thereby, for example, it becomes possible for a monitoring person to instruct an appropriate evacuation guidance from the monitoring center.

  Next, the car operation control means 14 determines whether the passenger is left in the car (S110). Here, when the car operation control means 14 determines whether or not the passenger is left in the car, the car operation control means 14 determines whether or not the car call has been performed when the fire signal is input in S102 (when a fire occurs). . It can be determined that the passenger is left in the car if the car was called at the time of the fire, while the passenger was left in the car if the car was not driven at the time of the fire. It is because it can be judged that it is not.

  If it is determined in S110 that the passenger is left in the car, the process proceeds to S111, and the car operation control means 14 refers to the information storage means 16 to determine whether the fire shutter has an exit. .

  If it is determined in S111 that the fire shutter is not equipped with an exit, the car operation control means 14 continues to close the car that is stopped on the evacuation floor (S112). This makes it possible to prevent the passenger from being guided in front of the fire shutter that is already closed. In S110, when it is determined that no passenger is left in the car, the process proceeds to S112.

  On the other hand, if it is determined in S111 that the fire shutter has an exit, the car operation control means 14 drives the car door device 50 to open the car that is stopped at the evacuation floor ( S113).

  Then, the car operation control means 14 keeps the door open until the escape door is once opened and then closed (S113, S114). That is, the car operation control means 14 continues to open the car stopped on the evacuation floor until there is a series of actions of opening and closing the exit door. As a result, it is possible to avoid a situation in which the passenger closes the door before the door is closed after the passenger has opened the exit door, and the passenger can be evacuated smoothly.

S113 and S114 will be specifically described.
When the passenger opens the exit door, the exit opening / closing state detecting means 12 inputs an opening signal of the exit door from the fire shutter device 20b with exit. The exit opening / closing state detection means 12 detects the opening operation of the exit door by inputting the door opening signal. When the passenger closes the exit door, the exit opening / closing state detecting means 12 inputs a closing signal for the exit door from the fire shutter device 20b with exit. The exit opening / closing state detection means 12 detects the closing operation of the exit door by the input of the door closing signal.
In this way, the escape opening / closing state detecting means 12 detects a series of actions of opening and closing the exit door. The car operation control means 14 extends a door opening waiting time set in advance based on the detection result of the escape outlet opening / closing state detection means 12, and has a series of actions of opening and closing the escape door. Wait until the door opens.

  In S114, when the escape outlet open / close state detection means 12 detects a series of opening and closing actions of the exit door, the car operation control means 14 announces that the door is closed, The door device 50 is controlled to shift to door closing (S115), and then the car is paused (S116).

  As described above, in the first embodiment, when the car operation control unit 14 determines that the fire shutter is installed before landing on the evacuation floor where the car is stopped, the fire shutter is opened and closed. Since opening and closing of the door is controlled accordingly, passengers can be evacuated smoothly.

Here, as an example, the elevator control device 10 switches the operation mode from normal operation to fire control operation due to the occurrence of a fire, and stops the car at a predetermined evacuation floor according to the fire occurrence situation such as a fire floor. explain. Note that the description of the same processing as in FIG. 2 is omitted as appropriate.

  In S201 to S204, the car operation control means 14 performs the same process as the process from S101 to S104, calls the car back to the evacuation floor, and determines whether a fire shutter is installed before landing on the evacuation floor. To do.

  In S204, when the car operation control unit 14 determines that the fire shutter is installed, the process proceeds to the next S205.

  In S205, the car operation control means 14 refers to the information storage means 16 to determine the type of fire shutter installed before landing on the evacuation floor where the car is stopped, and this is the fire shutter with exit. When it is determined that there is, the process proceeds to the next S212, and the same processes as the processes from S113 to S116 are performed (S212 to S215).

  That is, the car operation control means 14 changes the door opening standby time and makes the door open standby until there is a series of operations of opening and closing the exit door (S212, S213). This makes it possible to evacuate passengers smoothly.

  If it is determined in S205 that the fire shutter installed before landing on the evacuation floor has no exit, the process proceeds to the next S206, and the same processes from S105 to S109 and S112 are performed. Is performed (S206 to S211).

  Thus, in this second embodiment, when the car operation control means 14 determines that the fire shutter with exit is installed before landing on the evacuation floor where the car is stopped, the door of the exit Since opening and closing of the door is controlled according to the opening and closing of the passenger, passengers can be evacuated smoothly.
