DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power outage operation of an elevator that performs safe and optimal power outage operation when the power outage operation by a self-generated power supply and the emergency recall operation and fire fighting operation in case of fire overlap. It is about the method.

[0002]

2. Description of the Related Art For example, as shown in Japanese Utility Model Publication No. Sho 61-26303 or Japanese Examined Patent Publication No. Sho 63-342, generally, when a power failure occurs, the power source is switched to an emergency power source such as a private power generation facility and the power source is predetermined. Perform a return operation to return to the rescue floor. Due to the capacity of the emergency power supply, the return operation at the time of the power failure is often performed by the control device giving a return instruction one by one to the car that has been emergency stopped due to the power failure. After the return operation is completed, a predetermined arbitrary car is selected as a continuous operation car, and a car call in the building and a hall call are continuously provided.

In the event of a fire or the like, all calls are canceled, the in-car switch, weighing device, photoelectric device, and other passenger detection devices are disabled to disable the evacuation floor or the floor directly above or below it. Emergency recall operation (hereinafter referred to as recall operation) to go directly to the recall floor, and a fireman operation that can be operated only from inside the car by a fireman.

Originally, it is desirable that a fire-fighting elevator used for fire-fighting operation has a dedicated (fire-fighting) self-powered power supply so that it can be used even in the event of a power outage. The fire-fighting elevator may be operated as one of a plurality of elevators constituting a power failure operation. There is a causal relationship between a fire and a power outage.There is a high possibility that a power outage will occur due to the occurrence of a fire, and a power outage will occur during a recall operation or fire fighting operation in the event of a fire. It is very likely that you will have to use

[0005]

In general, when a power failure occurs during a recall operation in which a fire is caused to go straight to a recall floor, an emergency power source at the time of the power failure must be used as a power source for the recall operation. Will not be. On this occasion,
If the recall floor for recall operation is different from the rescue floor for return operation during a power outage, the car will return to the recall floor during recall operation because recall operation during a fire takes precedence over return operation during a power failure. Come back. Here, even if the vehicle returns to the predetermined recall floor by the recall operation, the predetermined position detector such as the passenger detection device does not operate, so that the control device is notified that the car has returned to the recall floor. No operation completion signal is output. Therefore, even if the car returns to the recall floor, the control device determines that the operation is continuing, and cannot output a return command to the other units due to the capacity of the emergency power supply. Passengers are trapped in another car that has stopped due to a power outage.

In addition, the car that has returned to the recall floor by the recall operation using the emergency power supply can perform the fire fighting operation. During the fire fighting operation using the emergency power supply, when the vehicle is stopped on the floor that is previously determined as the rescue floor at the time of a power failure due to the recall operation, an operation completion signal is output to the control device to inform the controller that the return operation has been completed. As a result, the control device gives a return command to another car, and as a result, the fire fighting operation is interrupted. Furthermore, a car that is not designated as a continuous operation unit at the time of a power failure cannot perform a fire fighting operation at the time of a power failure.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem. A first object of the present invention is to ensure that even if a power failure occurs during the recall operation, the other car is reliably connected to the other car after the recall operation is completed. The purpose of the present invention is to obtain a method of operating an elevator during a power outage, which can output a return instruction and operate the car efficiently. A second object of the present invention is to provide a method for operating an elevator during a power failure, which allows the firefighter operation to be continued as necessary even if a power failure occurs. Further, a third object is to provide an elevator power outage operation method that can forcibly and continuously operate a fire fighter-operable car.

The control panel 2b corresponding to the car # 2 also has the same configuration as the above-described control panel 2a, and a description thereof will be omitted.

FIG. 2 is a flowchart showing the operation of the elevator power failure operation program stored in the read-only memory 13 in the group control panel 1, and FIG. 4 is a flowchart showing an operation of an elevator power failure operation program stored in a memory 23.

Next, the operation of this embodiment will be described with reference to the flowcharts of FIGS. First, a description will be given of an operation when a power outage occurs and the self-generated power is established when the recall operation switch 6a of the car # 1 is turned on and the recall operation is performed. Here, according to the initial setting, the return sequence of the return operation at the time of the power failure is the order of the car # 1 and the car # 2, and the car that performs the continuous operation after the return is completed is the car # 2.

Based on the processing program in the group management panel 1,
The group management CPU 12 determines in step S1 whether or not the normal power supply is out of power based on the normally closed contact 4 that is closed when the normal power supply is energized. The process proceeds to S2, and it is determined whether or not private power generation has been established based on the normally closed contact 5 that is closed when the private power supply is turned off and the normal power supply is turned off and power is supplied by private power generation. When it is determined in steps S1 and S2 that the self-generated power has been established at the time of the power failure, the group management panel 1 proceeds to step S3 in order to perform a return operation at the time of the power failure due to the private power generation based on a predetermined rule. Then, it is determined whether or not the car # 1 has completed returning to the designated return floor. Here, since car # 1 is still in the recall operation and has not yet arrived at the recall floor, the car control panel 2a sends the group control panel 1
No return completion signal has been output for
4, the interface 15 sends a return instruction for controlling the car # 1 to return the car # 1 to the call-back floor from the interface # 1 to the car control panel 2a via the transmission line 3a.
Output via.

Next, the processing operation of each CPU 23a based on the processing program stored in the read-only memory 23a of each control panel 2a for controlling the car # 1 will be described with reference to FIG. During the recall operation, car # 1 loses power from the normal power supply (step S21), and
When the energization based on the self-generated power is detected (step S22), a return command that operates based on the self-generated power is input from the group management panel 1, and in step S23, the group management panel 1 is detected.
It is determined whether or not a return instruction has been received. Here, as described above, since the return instruction has been transmitted from the group management panel 1, the process proceeds to step S24.

In step S24, it is determined whether the emergency operation is being performed during the recall operation or the fire operation, and car # 1 is determined.
Since the recall operation, which is an emergency operation, is being performed, the process proceeds to step S25, and it is detected that the return operation and the recall operation at the time of the power failure overlap. Here, the continuation of the recall operation is selected from the relationship between the priority order of the return operation and the recall operation, and the recall operation is performed by the self-generated power.

Thereafter, the process proceeds to step S26, where the car # 1 arrives at the recall floor and opens, and when the arrival of the car is detected by a position detector or the like, the respective CPUs 23a
Even if the return floor in the return operation and the call-back floor arrived this time are not the same floor, after the return completion is output to the group management panel 1 via the transmission line 3a, the process proceeds to step S27. Car # 1 is suspended.

On the other hand, if it is determined in step S24 that the vehicle is not in an emergency operation, the process proceeds to step S28 to perform a return operation at the time of a power failure based on a self-generated power source due to the power failure, and return to a predetermined return floor. When the position detection or the like is detected by the position detector or the like, each unit CPU 23a transmits a return completion to the group management panel 1 in step S29.

If the return command is not transmitted from the group control panel 1 in step S23, it is determined that all returns have been completed, so the process proceeds to step S30, and the return command is sent to the car # 1. It is determined whether or not a continuous operation command to continuously operate only a specific car after the completion of all has been transmitted. Here, if the continuous operation command has been transmitted, the process proceeds to step S31, and it is determined whether the car # 1 is in the fire operation. If the fire operation is in progress, the process proceeds to step S32 to perform the fire fighting operation. If it is not during the fire-fighting operation, the process proceeds to step S33 to perform the continuous operation.

By transmitting the return completion to the group control panel 1 in step S26, the group control panel 1 proceeds to step S5 shown in FIG. 2 and determines whether return to car # 2 has been completed. Judge. Here is still basket # 2
Since the return of the car # 2 has not been completed, the process proceeds to step S6 and outputs a return instruction to the car # 2. Basket #
The operation of the car # 2 after receiving the return instruction is the same as the operation of the car # 1 described above, and thus the description is omitted.
After the return of the car # 2 is completed, if necessary, the car # 1 and the car # 2 are put on standby to perform the fire fighting operation.

According to this embodiment, even if the recall operation is performed by the self-generated power source at the time of a power failure, the arrival at the recall floor is detected by the position detector or the like, and the completion of the return to the recall floor is always completed. By outputting to the group control panel 1, the group control panel 1 can output the next return command to the other units, and terminate the return operation quickly and surely when a fire is detected. It is possible to prevent passengers from being trapped in the car.

Embodiment 2 FIG. In the present embodiment, after the recall operation is completed, both the fire extinguisher operation switches 7a and 7b of the car # 1 and the car # 2 are turned on, and a power outage occurs during the fire extinguishing operation, and # 1 when the self-generated power is established. The operation during power outage of the second and third units will be described with reference to a flowchart showing the operation of the elevator power outage operation program stored in the read-only memory 13 in the group control panel 1 of FIGS. Here, according to the setting, the return sequence of the recall operation is the order of the car # 1 and the car # 2, and the priority continuous operation during the fire fighting operation is the car # 1.

Based on the processing program in the group control panel 1,
The group management CPU 12 determines in step S11 whether or not the normal power supply is out of power based on the normally closed contact 4 that is closed when the normal power supply is energized. Alternatively, the power source is switched to private power generation manually. Then, step S12
Then, it is determined whether or not private power generation has been established based on the normally closed contact 5 that is closed when the private power supply is turned off and the normal power supply is turned off and the power supply by private power generation is performed. If it is determined in step S11 and step S12 that the self-generated power has been established at the time of the power failure, the group control panel 1 performs a return command based on a predetermined rule in order to perform a return operation at the time of the power failure due to private power generation. Is output, and control is performed so that the cars return to the return floor in order.

Thereafter, the flow shifts to step S13 to determine whether or not the car # 1 is in the fire fighting operation. here,
Since the car # 1 is in the fire fighting operation, the process proceeds to step S14, and the transmission line 3a is transmitted to each car control panel 2a to continue the fire fighting operation of the car # 1.
A continuous operation command is output via. At this time, the steps S13 and S14 are repeated while the fire fighter operation switch 7a of the car # 1 is on.

Next, a processing operation of each CPU 23a based on a processing program stored in the read-only memory 23a of each car control panel 2a for controlling the car # 1 will be described with reference to FIG. The car # 1 detects a power outage of the normal power supply (step S21) and a power supply based on the self-generated power supply (step S22) during the fire fighting operation, and issues a return command to operate based on the self-generated power supply from the group management panel 1. Upon input, in step S23, it is determined whether a return instruction from the group management panel 1 has been received. Here, if the return instruction has not been received, the process proceeds as in the first embodiment.

On the other hand, if the return command has been transmitted from the group control panel 1, the process proceeds to step S24, where it is determined whether the emergency operation is being performed during the recall operation or the fire operation, and the # 1 car is operated in the emergency operation. Because the firefighter was driving
The process proceeds to step S25, and it is detected that the return operation and the firefighter operation at the time of the power failure overlap. Here, the continuation of the fireman's operation is selected from the relationship between the priority order of the return operation and the fireman's operation, and the fireman's operation is performed by the self-generated power.

Thereafter, the process proceeds to step S26, and when it is detected by the position detector or the like that the car # 1 has completed returning to the designated floor designated by the fireman, each car CPU 23a
Even if the return floor in the return operation and the designated floor in the firefighter operation that has arrived this time are not the same, after outputting the return completion via the transmission line 3a to the group management panel 1, the fireman If there is no such operation, the process proceeds to step S27, and the operation of the car # 1 is suspended. On the other hand, in step S24,
When it is determined that the vehicle is not in an emergency operation, the operation is the same as in the first embodiment, and a description thereof will be omitted.

By transmitting the return completion to the group control panel 1 in step S26, the group control panel 1 again proceeds to step S13 shown in FIG. 4, and the fire fighting operation switch 7a of the car # 1 is set. Is determined to be On, and even if the return completion signal is output from the car # 1, the car # 1 having the higher priority is given while the fire fighting operation is instructed to the car # 1. Continue operation of Unit No. Then, the fire fighter operation switch 7a of the car # 1
Is turned off, the process proceeds to step S15, and the car #
It is determined whether or not the fire fighting operation switch 7b is turned on for the second fire fighting operation. Step S15
When the car # 2 is in the fire fighting operation, the process proceeds to step S16, and the group control panel 1 outputs a continuous operation command to each of the vehicle control panels 2b via the transmission line 3b. The operation of the car # 2 based on the continuous operation command is the same as that of the car # 1 described above, and a description thereof will be omitted.

In step S15, when the fire fighting operation of the car # 2 is completed, the flow proceeds to step S17.
A continuous operation command is output to the car # 1 as an emergency elevator that performs a predetermined fire fighting operation,
It is compulsorily designated as a continuous operation unit.

According to this embodiment, even if the fire fighting operation is performed by the self-generated power supply at the time of a power failure, the arrival at the designated floor by the fire fighter is detected by the position detector or the like, and the vehicle arrives at the designated floor. Even if the return completion is output to the group control panel 1, the group control panel 1 outputs
An emergency power supply by private power generation can be continuously supplied to the car and the fire fighting operation can be continued, so that an emergency fire extinguishing operation can be continuously performed. Also, if the continuous operation unit designated at the time of the power failure is different from the firefighter operation unit, the car that can perform the firefighter operation will be instructed to forcibly continue operation. Can support firefighting activities without hindering firefighters' activities during a fire.

[0034]

Since the present invention is configured as described above, it has the following effects.

When the supply of normal power is stopped, a first step of switching to the supply of emergency power, a second step of detecting an emergency recall operation in the event of a fire, and a first step and a second step are performed. When the recall operation based on the power supply for
A third step of detecting the arrival of the car at the recall floor defined as the emergency recall operation, and, when the arrival of the car at the recall floor is detected by the third step, this is returned to the return floor. And a fourth step of instructing another car to return to the return floor at the time of a power failure as an arrival at the vehicle, so that even if a power failure occurs during the emergency operation, The return instruction is output to the other cars, so that the car can be operated efficiently. Therefore, the time during which passengers are trapped in the car can be reduced.

Also, after all the cars arrive or return to the recall floor or the return floor, the fire-fighting operation is performed by the car that performed the recall operation. Therefore, even if a power outage occurs during an emergency operation, in the event of an emergency, Only the car that can perform the emergency operation can continuously operate, and the car can be operated efficiently. Therefore, by continuing the emergency operation in the event of a fire such as a fire fighting operation, it is possible to support fire extinguishing activities.

Further, since a priority operation is performed for a specific car capable of performing a fire fighting operation among a plurality of installed cars, a continuous operation is forcibly performed on a car capable of emergency operation. Only a predetermined car that can be designated and can be operated in an emergency in an emergency can be operated, and the car can be operated efficiently.
