Abstract

PROBLEM TO BE SOLVED: To perform safe and optimal power failure time operation by switching it to supply of an emergency power source at power failure time, detecting an arrival of a car at the recall floor when emergency recall operation at fire time is detected at this time, and generating a return command to the other cars when the arrival is detected. SOLUTION: In the case where recall operation of a car #1 machine is performed, power failure is caused, and when a private power generation power source is established, a group control board 1 judges whether or not the car #1 machine completely returns to the designated return floor, and in the case of NO, a return command is outputted to a respective unit control board 2a. The car #1 machine arrives at the recall floor, and opens a door, and when the completion of an arrival is detected by a position detector or the like, a CPU 22a stops operation of the car #1 machine after the completion of a return is outputted to the group control board 1 even if the return floor and this time arrived recall floor are not the same. The group control board 1 outputs a return command to a car #2 machine by judging whether or not a return is completed by transmission of the completion of a return.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator power failure operation for performing safe and optimal power failure operation when power failure operation by a private power source and emergency call back operation / fireman operation in case of fire overlap. It is about the method.

[0002]

2. Description of the Related Art Generally, for example, as shown in Japanese Utility Model Publication No. 61-26303 or Japanese Patent Publication No. 63-342, 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 set in advance. Perform a return operation to return to the rescue floor. Due to the capacity of the emergency power source, the return operation at the time of power failure is often performed by the controller giving a return command to each car that has stopped due to the power failure. After the return operation is completed, a car of a predetermined arbitrary number is selected as a continuous operation number and continuously serviced for car calls and hall calls in the building.

When a fire or the like occurs, all calls are canceled and the passenger detection devices such as the in-car switch, the weighing device and the photoelectric device are disabled, and the evacuation floor or the floor immediately above or below it ( Perform emergency call-back operation (hereinafter referred to as call-back operation) to go straight to the call-back floor) and fire-fighting operation that consists of a firefighter operation that can be performed only from inside the car by a fireman.

Originally, it is desirable that the fire-fighting elevator used for fire-fighting operation has a private (fire-fighting) private power source so that it can be used even during a power failure. The fire-fighting elevator may be operated as one of the multiple units that constitute operation during a power failure. There is a causal relationship between a fire and a power outage, and there is a high possibility that a power outage will occur due to a fire, and a power outage occurs during the recall operation or firefighter operation during a fire. It is very likely that you will have to use.

[0005]

Generally, when a power failure occurs during a call-back operation in which a vehicle goes straight to the call-back floor due to a fire, the power supply for the call-back operation should use an emergency power supply at the time of power failure. Will not happen. On this occasion,
If the recall floor during the recall operation and the rescue floor during the return operation during a power outage are different, the recall operation during a fire has priority over the return operation during a power outage, so the car will return to the recall floor during the recall operation. Come back. Here, even if the car returns to the predetermined call-back floor by the call-back operation, the predetermined position detector such as the passenger detection device does not operate, so the controller is notified that the car has returned to the call-back floor. No operation completion signal is output. Therefore, in the control device, even if the car returns to the call-back floor, it is determined that the operation is continuing, and therefore it is not possible to output a return command to other units due to the capacity of the emergency power supply, Passengers are trapped in another car that was stopped due to a power outage.

Further, the car returned to the call-back floor by the call-back operation by the emergency power supply can be operated by the firefighter. During the firefighter operation with the emergency power supply, if the vehicle stops due to a recall operation during the power failure, the operation completion signal is output to the control device to inform that the return operation is complete. As a result, the control device gives a return command to the other units, and as a result, the firefighter operation is interrupted. Furthermore, a car that is not designated as a continuous operation unit at the time of power failure cannot perform firefighter operation at the time of power failure.

The present invention has been made in order to solve such a problem. A first object of the present invention is to ensure that even if a power failure occurs during a call-back operation, after the call-back operation is completed, another car is surely delivered. To output a return command to efficiently operate the car and obtain an operation method for an elevator during a power failure. A second object is to obtain an elevator power failure operation method capable of continuing the firefighter's operation as long as necessary even when a power failure occurs. Further, a third object is to obtain an elevator power failure operation method capable of forcibly and continuously operating a fire engineer-operable unit.

[0008]

In an elevator power failure operation method according to the present invention, there is provided a first step of switching to a supply of emergency power when the supply of a normal power supply is stopped, and an emergency call-back operation in case of a fire. Detecting the arrival of the car at the call-back floor defined as the emergency call-back operation when the call-back operation based on the emergency power supply is detected by the second step of detecting the emergency call and the first and second steps. When the arrival of the car at the call-back floor is detected by the process 3 and the third process, the car is instructed to arrive at the return floor and the other cars are instructed to return to the return floor at the time of power failure. And a fourth step to be performed.

Further, after all the cars arrive at or return to the call-back floor or the return floor, the firefighter operation is performed by the car that has performed the call-back operation.

In addition, the priority operation is performed for a specific car that can be operated by a firefighter from a plurality of installed cars.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1. FIG. 1 is an overall configuration diagram showing the overall configuration of an elevator power failure operation device. In the figure, reference numeral 1 is a group control panel for giving each unit control panel 2 a return operation command and a continuous operation command at the time of a power outage based on information from the power outage from the outside and information from each unit control panel. An input interface 11 for inputting external information such as a power failure information based on a normally closed contact 4 that is closed when energized by a power source and a normally open contact 5 that is closed when energized by private power generation is performed when the normal power source is down, Group management microprocessor 12 (hereinafter referred to as group management CPU) that performs various group calculations and control based on external information and control programs, and read out program for elevator power failure operation in group management panel 1 The return operation at the time of power failure, the continuous operation command, etc. are output to each unit control panel 2 via the dedicated memory 13, the write / read only memory 14, and the transmission line 3, and the return operation is also performed. Ryo detection, fireman operation detecting the like and an interface 15 to be input.

Reference numeral 2 denotes a function for causing the car to operate during a power failure by external power failure information and a return operation command and a continuous operation command at the time of a power failure from the group control panel, an external call back operation command, and a firefighter. Recall operation by operation command,
It is a control panel for each unit that has the function of operating a firefighter. In the present embodiment, for the sake of explanation, there are two cars, and the respective control boards 2 are the control boards 2a and # 2 corresponding to the # 1 machine, respectively.
Although the description will be made for each unit control panel 2b corresponding to the second car, the same is true even if the number of car cars is further plural.

Each car control panel 2a for controlling the car # 1
Is a normally-closed contact 4, a normally-open contact 5, and a recall operation switch 6a for recalling an elevator in the event of a fire installed in a hall or the like, and a fireman operation switch 7a for performing an elevator firefighter operation in an elevator when a fire is installed in a car. External information and
Various calculations are performed based on the input interface 21a for inputting the return operation command, the continuous operation command, etc. from the group control panel 1 via the transmission line 3a, the external information and the control program,
Each of the microprocessors 22a for controlling the car (hereinafter, each CPU), the read-only memory 23a, the write / read-only memory 24a, and the car # in which the program of the elevator operation in the control panel 2a during the power failure is written.
Interface 25 for exchanging data with Unit 1
a. Further, each unit control panel 2 outputs a return operation completion signal to the group management panel 1 at the time of power failure.

Since each unit control panel 2b corresponding to the car # 2 has the same structure as each of the above-described unit control panels 2a, the description thereof will be omitted.

FIG. 2 is a flow chart showing the operation of the elevator power failure operation program stored in the read-only memory 13 in the group control board 1, and FIG. 3 is a read-only operation in each unit control board 2. It is a flowchart which shows operation | movement of the elevator power failure operation program stored in the memory 23 inside.

Next, the operation of this embodiment will be described with reference to the flowcharts of FIGS. First, the operation when the call-back operation switch 6a of the car # 1 is turned on and a call-back operation is performed and a power failure occurs and the private power source is established will be described. Here, according to the initial setting, the return order of the return operation at the time of power failure is the order of the car # 1 and the car # 2, and the car to be continuously operated after the completion of the return is the car # 2.

Based on the processing program in the group control panel 1,
The group management CPU 12 determines in step S1 whether or not the normal power source has a power failure based on the normally closed contact 4 that is closed when the power source is energized. In S2, it is determined whether or not the private power generation is established based on the normally closed contact 5 that is closed when the private power generation source is energized by the private power generation when the normal power source is down. When it is determined in step S1 and step S2 that the private power source is established during a power failure, the group management panel 1 proceeds to step S3 in order to perform a return operation at the time of a power failure due to private power generation based on a predetermined rule. After the transfer, it is determined whether or not the car # 1 has completed the return to the designated return floor. In this case, the car # 1 is in the middle of the call back operation and has not yet arrived at the call back floor.
No return completion signal has been output for step S
4, the interface 15 sends a return command for controlling the car # 1 to the car # 1 so that the car # 1 can be returned to the call-back floor.
Output via.

Next, the processing operation of each CPU 23a based on the processing program stored in the read-only memory 23a of the control board 2a for controlling the car # 1 will be described with reference to FIG. Car # 1 has a normal power failure during the recall operation (step S21), and
When the energization based on the private power source (step S22) is detected, a return command for operating based on the private power source is input from the group management board 1, and in step S23, the group management board 1
Judge whether or not the return instruction from is received. Here, as described above, since the return command has been transmitted from the group management board 1, the process proceeds to step S24.

In step S24, it is judged whether the operation is the recall operation or the emergency operation during the fire fighting operation.
Since the Unit No. was in the emergency call-back operation, the process proceeds to step S25, and it is detected that the return operation due to the power failure and the call-back operation overlap. Here, continuation of the call-back operation is selected from the relationship of the priority order of the return operation and the call-back operation, and the call-back operation is performed by the private power source.

Thereafter, at step S26, when the car # 1 arrives at the call-back floor and the door is opened and the arrival of the car is detected by the position detector or the like, the CPU 23a for each car
Even if the return floor in the return operation and the call-back floor that arrived this time are not the same floor, after outputting the return completion to the group control panel 1 via the transmission line 3a, the process proceeds to step S27, Car # 1 is out of service.

On the other hand, if it is determined in step S24 that the emergency operation is not being performed, the process proceeds to step S28, and the return operation at the time of power failure is performed based on the privately-generated power source due to the power failure, and the vehicle is returned to the predetermined return floor. When this is detected by the position detector or the like, each of the CPUs 23a transmits the return completion to the group management board 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 the return has been completed. Therefore, the process proceeds to step S30, and the return command is issued to the car # 1. It is determined whether or not a continuous operation command for continuously operating only a specific car after all the operations are transmitted. Here, if the continuous operation command is transmitted, the process proceeds to step S31 to determine whether or not the car # 1 is in the fire fighting operation, and if it is in the fire fighting operation, the process proceeds to step S32 to perform the firefighter operation. If the fire fighting operation is not in progress, the process proceeds to step S33 and the continuous operation is performed.

When the return completion is transmitted to the group management board 1 in step S26, the group management board 1 proceeds to step S5 shown in FIG. 2 to determine whether or not the return is completed for the car # 2. To judge. Here we are still in basket # 2
Since the return of the car No. is not completed, the procedure goes to step S6 to output a return command to the car # 2. Basket #
The operation after receiving the return instruction of the second car is the same as the operation of the car # 1 described above, and thus the description thereof is omitted.
After the return of the car # 2 is completed, the car # 1 and the car # 2 are put on standby so that the firefighters can operate as necessary.

According to the present embodiment, even if the call-back operation is performed by the private power source at the time of power failure, the arrival of the call-back floor is detected by the position detector or the like, and the return completion which always arrives at the call-back floor is detected. By outputting to the group control panel 1, the group control panel 1 can output the next return command to other units, and when the fire is detected, the return operation can be completed quickly and surely. As a result, the passengers can be prevented from being trapped in the car.

Embodiment 2. In the present embodiment, after the recall operation is completed, the firefighter operation switches 7a and 7b of both the car # 1 and the car # 2 are turned on, a power failure occurs during the operation of the firefighter, and the self-generated power source is established # 1. The operation of the power failure operation in Units No. 2 and No. 2 will be described with reference to the flowcharts of FIGS. 3 and 4 showing the operation of the elevator power failure operation program stored in the read-only memory 13 in the group control panel 1. Here, depending on the setting, the return order of the recall operation is the order of car # 1 and car # 2, and the priority continuous operation during firefighter operation is car # 1.

Based on the processing program in the group management board 1,
In step S11, the group management CPU 12 determines whether or not the normal power source has a power failure based on the normally-closed contact 4 that is closed when the normal power source is energized. Alternatively, the power source is switched to private power generation manually. Then, step S12
Then, it is determined whether or not the private power generation is established on the basis of the normally closed contact 5 that is closed when the private power generation is energized by the private power generation when the normal power supply is down. When it is determined in step S11 and step S12 that the private power generation is established during a power failure, the group control panel 1 causes a return command based on a predetermined rule to perform a return operation during a power failure due to private power generation. Is output, and control is performed so that the cars are sequentially returned to the return floor.

Thereafter, the process proceeds to step S13, and it is determined whether or not the car # 1 is in the fire engineer's operation. here,
Since the car # 1 is in the middle of fire engineer operation, the process proceeds to step S14, and the transmission line 3a is transmitted to each car control panel 2a so that the car # 1 can continue the fireman operation as it is.
The continuous operation command is output via. At this time, the processes of steps S13 and S14 are repeated while the firefighter operation switch 7a of the car # 1 is turned on.

Next, in order to control the car # 1, the processing operation of each CPU 23a based on the processing program stored in the read-only memory 23a of the control board 2a will be described with reference to FIG. Cage # 1 detects a power outage of the normal power supply (step S21) and the energization based on the private power generation (step S22) while the firefighter is operating, and issues a return command to operate from the private power supply from the group control panel 1. When input, in step S23, it is determined whether or not the return instruction from the group management board 1 has been received. Here, if the return instruction has not been received, the process proceeds in the same manner as in the above-described 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, and it is judged whether or not the emergency operation is being performed during the recall operation or the fire fighting operation, and the car # 1 is in the emergency operation. Because I was driving a firefighter,
In step S25, it is detected that the return operation due to the power failure and the firefighter operation overlap. Here, the continuation of the firefighter operation is selected based on the priority relationship between the return operation and the firefighter operation, and the firefighter operation is performed by the private power source.

After that, the process moves to step S26, and when it is detected by the position detector that the car # 1 has completed the return to the designated floor designated by the firefighter, each unit CPU 23a
Even if the return floor in the return operation and the designated floor in the firefighter operation that arrived this time are not the same, after the return completion is output to the group control panel 1 via the transmission line 3a, the firefighter If there is no driving by, the process proceeds to step S27, and the operation of the car # 1 is stopped. On the other hand, in step S24,
When it is determined that the emergency operation is not in progress, the description is omitted because it is the same as in the above-described first embodiment.

When the return completion is transmitted to the group control panel 1 in step S26, the group control panel 1 shifts to step S13 shown in FIG. 4 again, and the firefighter operation switch 7a of the car # 1 is operated. Is determined to be ON, and even if the return completion signal is output from car # 1, car # 1 with a high priority is instructed while fire engineer operation is instructed to car # 1. Continue operation of Unit No. After that, the firefighter operation switch 7a of car # 1
Is turned off, the process proceeds to step S15 and the car #
It is determined whether the firefighter operation switch 7b is turned on for Unit 2 and the firefighter operation is in progress. Step S15
When the car # 2 is in the firefighter operation, the group control panel 1 outputs a continuous operation command to the individual control panel 2b via the transmission line 3b. Since the operation of the car # 2 based on the continuous operation command is the same as that of the car # 1 described above, the description thereof will be omitted.

In step S15, when the fire engineer operation of the car # 2 is completed, the process proceeds to step S17,
A continuous operation command is output to car # 1 which is an emergency elevator that operates the firefighters determined in advance.
It is forcibly designated as a continuous operation machine.

According to this embodiment, even if the firefighter is operating with the private power source during a power failure, the position detector or the like detects that the firefighter has arrived at the designated floor and arrives at the designated floor. Even if the return completion is output to the group management panel 1, the group management panel 1 will
Since it is possible to continuously supply the car with an emergency power source by private power generation and continue the operation of the firefighter, it is possible to continue fire extinguishing activities in an emergency. Also, if the continuous operation number specified at the time of power failure and the firefighter operation number are different, it will be instructed to force the car that can be firefighter operation to continue operating forcibly, It is possible to support fire extinguishing activities without disturbing the activities of firefighters during a fire.

[0034]

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

When the supply of the normal power supply is stopped, the first step of switching to the supply of the emergency power supply, the second step of detecting the emergency call-back operation in case of a fire, and the first and second steps are performed. When a recall operation based on the
The third step of detecting the arrival of the car at the call-back floor defined as the emergency call-back operation, and when the arrival of the car at the call-back floor is detected by the third step, this is returned to the return floor. Even if a power outage occurs during emergency operation, it is possible to ensure that another car will be instructed to return to the return floor when there is a power outage. It is possible to output a return command to another car and operate the car efficiently. Therefore, it is possible to shorten the time during which passengers are trapped in the car.

In addition, after all the cars arrive at or return to the call-back floor or the return floor, the fire-fighter operation is performed by the car that has carried out the call-back operation, so even if a power failure occurs during an emergency operation, in case of an emergency Only the car that can perform the emergency operation can be continuously operated, and the car can be operated efficiently. Therefore, it is possible to support fire extinguishing activities by continuing emergency operation in case of fire such as firefighter operation.

Further, from a plurality of installed cars, a specific car that can be operated by a firefighter can be preferentially operated, so that a continuous operation can be forcibly performed on an emergency-operable car. Only a predetermined car that can be designated and can perform emergency operation in an emergency can be operated, and efficient car operation can be performed.
