Detailed Description

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the present specification and the drawings, the same reference numerals are given to components having substantially the same function and structure, and redundant description is omitted.

[ first embodiment ]

< example of integral Structure of Elevator >

Fig. 1 is an overall configuration diagram of an elevator 1.

The elevator 1 includes a car 2 that can be raised and lowered inside a hoistway 10. The hoistway 10 is provided with a pit excavated from the 1 st floor (lowest floor) of the building, in addition to each floor having the lowest floor of 1 st floor and the highest floor of n th floor. In addition, the fire source floor where the fire breaks out is set as k floors.

The elevator 1 can be carried by general passengers at ordinary times, and can be operated for fire protection only allowing rescue workers to carry in emergency. The elevator 1 includes a car 2, a car device 3, a tail rope 4, a sheave 5, a rope 6, a hoisting machine 7, and a balance weight 8. Inside the hoistway 10, a metal mesh 11 for protecting a distribution board and the like (not shown) and an elevator control device 12 are provided.

The tail cable 4 connects the car 2 to a hoistway 10 in which the car 2 is raised and lowered. The tail cable 4 is generally a cable in which a plurality of multi-core cables such as a control cable and an electric power cable, a wire rope as a reinforcing member for supporting the weight of the tail cable 4, and the like are covered with an insulating material. The tail cable 4 is formed to have a substantially rectangular cross section in order to prevent twisting, and is bent so as to always generate a bent portion in consideration of the length of the running range of the car 2.

The car 2 includes a door 2a, a passenger detection sensor 2b, an in-car operation panel 2c, and a switch box 2 d. When the car 2 stops at a destination floor registered by a passenger operating the in-car operation panel 2c, the door 2a and the hall door 13 (see fig. 2 described later) are opened (hereinafter referred to as "door open"). While the car 2 is traveling, the doors 2a and the hall doors 13 are closed (hereinafter referred to as "closed doors"). A passenger detection sensor 2b that detects the boarding and landing of a passenger is provided on the door 2 a. When a passenger passes through the opened door 2a, the passenger detection sensor 2b detects that the passenger is ascending and descending the car 2, and transmits detection information to the elevator control device 12 through the tail cable 4.

In addition, at the time of maintenance inspection of the elevator 1, the switch box 2d provided in the car 2 is opened by a maintenance worker. The maintenance person can change the operation mode of the elevator 1 from the normal operation mode to the maintenance operation mode by means of the switch box 2 d. In the maintenance operation mode, the car 2 is controlled not to run even if the passenger presses the call button 14 located at each floor. Then, in the maintenance operation mode, the traveling speed of the car 2 traveling in the hoistway 10 is controlled to be lower than the traveling speed in the normal operation mode.

A car device 3 is mounted on the bottom surface of the car 2, and is connected to one end of a tail cable 4. The car device 3 outputs information on opening and closing of the door 2a, information on the number of passengers or the weight of the passengers riding in the car 2, and the like to the elevator control device 12 through the tail cable 4.

The other end of the tail cable 4 is connected to an elevator control device 12 provided in the hoistway 10. The elevator control device 12 controls the operation of the elevator 1. A control signal for controlling the operation of the car 2, electric power, and the like are transmitted from the elevator control device 12 to the car 2 via the tail cable 4. On the other hand, information such as a destination floor instructed by a passenger who has mounted the car 2, and a current floor where the car 2 is located is transmitted from the car 2 to the elevator control device 12 via the tail cable 4.

Two sets of pulleys 5 are provided on the ceiling of the hoistway 10. The car 2 is mounted on one end of the rope 6 via a sheave 5, and a balance weight 8 is mounted on the other end of the sheave 6 via a hoisting machine 7 installed on the ground in the pit. The balance weight 8 is used to keep balance with the car 2 attached to the rope 6.

A metal mesh 11 is provided on one wall surface in a hoistway 10 in which an elevator control device 12 is installed. Various devices (not shown) are provided between the wire mesh 11 and the wall surface of the hoistway 10, in addition to the elevator control device 12 that connects the other end of the tail cable 4. The wire mesh 11 is used to prevent the tail cable 4 swinging in the front width direction from coming into contact with equipment and the like provided in the hoistway 10 as the car 2 ascends and descends.

In the normal operation mode, the hoisting machine 7 winds up the rope 6 under the control of the elevator control device 12, and raises and lowers the car 2 to the destination floor instructed by the passenger while adjusting the traveling speed of the car 2. In the maintenance operation mode, the hoisting machine 7 winds up the rope 6 and the car 2 travels under the control of a maintenance worker who is present at the floor.

In the present embodiment, a fire-fighting operation mode for instructing the operation of the car 2 by a rescuer such as a firefighter is prepared. In the fire-fighting operation mode, the car 2 is raised and lowered to a destination floor instructed by a rescuer while keeping the door 2a of the car 2 open by the control of the elevator control device 12. In the fire-fighting operation mode, the control is performed so that the car 2 does not run even if the call buttons 14 located at the respective floors are pressed by passengers. In the fire-fighting operation mode, the traveling speed of the car 2 traveling in the hoistway 10 is controlled to be lower than the traveling speed in the normal operation mode and the maintenance operation mode. The details of the fire fighting operational mode are described later.

Next, various sensors configured in the car 2 will be described.

Fig. 2 is a diagram showing an example of installation of the in-car sensor. Fig. 2 shows a state of the car 2 stopping at 1 floor (evacuation floor) as viewed from the front width direction.

In fig. 2, the hall door 13 on floor 1 and the car door 2a of the car 2 are in an open state. Also, on the door pocket of the hall door 13, a call button 14 and an emergency call return operation button 15 are provided.

In the normal operation mode, when a person in the hall presses the call button 14, a call of the floor on which the call button 14 is installed is registered to the elevator control device 12. The elevator control device 12 stops the car 2 at the floor at which the call is registered.

When a fire or the like occurs, the emergency call return operation button 15 is pressed by a manager of the building or the like. For example, when a person in the hall presses the emergency call return operation button 15, the elevator control device 12 is notified of the occurrence of a fire. The elevator control device 12 moves the car 2 to a call return floor (usually 1 floor) registered in advance, and opens the door after stopping the car. In this state, even if the call button 14 is pressed on another floor, a call is not registered. Then, the elevator control device 12 causes the car 2 to perform an inspection operation. The inspection operation is an operation for stopping the car 2 layer by layer and opening the door while the car 2 is traveling to the highest floor, and for causing the in-car sensor 20 to detect the condition of each floor.

The car 2 has an in-car sensor 20 that detects detection information required for rescue activity for each floor at which the car 2 is stopped. The in-car sensor 20 is used as an example of a detection portion mounted inside the car 2. The in-car sensor 20 includes sensors such as an in-car camera 21, a temperature sensor 22, and an oxygen concentration sensor 23. The in-car sensor 20 detects the state in the car, and outputs detection information to the elevator control device 12 via the tail cable 4 shown in fig. 1.

The in-car camera 21 is an example of a sensor that outputs an image obtained by imaging the inside of the car 2. The in-car camera 21 can photograph the inside of the car 2. The in-car camera 21 may be provided at a position where it can photograph the situation of the elevator hall when the hall door 13 is opened. The in-car camera 21 outputs image data obtained by capturing a state in the car 2 with a still image or a moving image as detection information.

The temperature sensor 22 is an example of a sensor that measures the temperature inside the car 2 and outputs temperature information. When the car 2 opens the door, the temperature measured by the temperature sensor 22 is the hall temperature. The temperature sensor 22 outputs the detected temperature as detection information.

The oxygen concentration sensor 23 is an example of a sensor that measures the oxygen concentration in the car 2 and outputs oxygen concentration information. When the car 2 is opened, the oxygen concentration measured by the oxygen concentration sensor 23 is the hall oxygen concentration. The oxygen concentration sensor 23 outputs the detected oxygen concentration as detection information.

The in-car sensor 20 includes at least one of an in-car camera 21, a temperature sensor 22, and an oxygen concentration sensor 23. The detection information output from the in-car sensor 20 to the elevator control device 12 includes at least one of temperature information, oxygen concentration information, and an image output from the in-car sensor 20.

Next, a description is given of a configuration example of the in-car operation panel 2 c.

Fig. 3 is a diagram showing an example of an external configuration of the in-car operation panel 2 c.

The in-car operation panel 2c includes a display panel 31, a fire-fighting operation portion 32, a destination floor button 33, and an open/close button 34. A switch box 2d is provided below the car-interior operation panel 2 c.

The display panel 31 displays the number of floors at which the car 2 stops, an arrow indicating the direction in which the car 2 moves up and down, various information notifying passengers in the car 2, and the like. When a fire breaks out in a building, the operation mode is changed to the inspection operation mode automatically or by a manager of the building or the like, and therefore a character "inspection operation is displayed on the display panel 31. On the display panel 31, information for warning the passengers to quickly get away from the car 2 and information indicating that the destination floor is changed to the evacuation floor and the car 2 is traveling are displayed.

The fire-fighting operation unit 32 is used when the car 2 is operated by switching to the fire-fighting operation mode. The fire-fighting operation unit 32 has a primary fire-fighting switch 32a, a secondary fire-fighting switch 32b, and an emergency stop switch 32 c. In addition, in the fire fighting operation mode, primary fire fighting operation and secondary fire fighting operation can be performed. When the first fire switch 32a is turned ON by inserting a key into the rescuer, the operation is switched to the first fire operation. In a fire fighting operation, after the rescuer presses the destination floor button 33 and the door 2a is closed, the car 2 travels to the destination floor at a rated speed. Then, the car 2 stops at the destination floor, and the rescuer opens the door when pressing the door opening button.

If the primary fire switch 32a is in the ON state, the rescuer can switch the secondary fire switch 32b to the ON state by inserting a key, and the operation is switched to the secondary fire protection operation. However, in order to turn ON the secondary fire switch 32b, the rescuer must keep the key of the primary fire switch 32a in the ON state. In the secondary fire protection operation, when the rescuer continuously presses the secondary fire switch 32b and the destination floor button 33 for several seconds at the same time, the car 2 starts even if the door 2a is not closed. When the car 2 travels during the secondary fire protection operation and the rescuer releases the key of the secondary fire switch 32b, the secondary fire switch 32b is automatically turned OFF, and the car 2 stops. In addition, if emergency stop is required in the secondary fire fighting operation, the emergency stop switch 32c is used. When the emergency stop switch 32c is pressed by the rescuer, the running car 2 is stopped emergently.

The destination floor button 33 enables selection and registration of a destination floor requested by a passenger. In fig. 3, only the destination floor buttons 33 of the 1 st floor, the k th floor, and the n th floor shown in fig. 1 are shown.

The open/close button 34 is a button for instructing opening/closing of the door 2 a. In conjunction with the opening and closing of the door 2a, a hall door 13 (see fig. 2) of the floor at which the car 2 is stopped is also opened and closed.

Next, a description will be given of a configuration example of an elevator control system for remotely monitoring the elevator 1.

Fig. 4 is a block diagram showing a configuration example of the elevator control system 100.

The elevator control system 100 has a function of monitoring a disaster situation of a building for each floor by operating the elevator 1 operated in the building in which a disaster has occurred. The elevator control system 100 includes an elevator control device 12, an in-car sensor 20, a monitoring device 50, and a rescuer terminal 60. The elevator control device 12 and the monitoring device 50 can communicate with each other via a network N such as the internet. Further, the monitoring device 50 can provide various information to the rescuer terminal 60 via the network N.

The detection information indicating the state in the car 2 detected by the in-car sensor 20 as described above is input to the elevator control device 12.

The elevator control device 12 includes an operation mode changing unit 41, a detection information storage unit 42, an operation control unit 43, and a notification unit 44.

The operation mode changing unit 41 changes the operation mode of the car 2 to any one of a normal operation mode, a maintenance operation mode, and a fire protection operation mode. The information of the operation mode switched by the operation mode changing unit 41 is output to the operation control unit 43.

The detection information storage unit 42 stores the detection information and the result of the security judgment. The result of the safety determination is, for example, information on which floor is abnormal and entry of rescuers is restricted when a fire breaks out in the building. The details of the detection information stored in the detection information storage unit 42 will be described later with reference to fig. 5.

The operation control unit 43 controls the operation of the car 2 in accordance with the operation mode changed by the operation mode changing unit 41. When the operation mode is changed to the inspection operation mode at the time of occurrence of a disaster, the operation control unit 43 determines the safety for each floor to which the car 2 stops based on the detection information collected from the in-car sensor 20. Here, the operation control unit 43 writes the detection information and the determination result of the safety that determines that there is an abnormality in the floor whose detection information is different from the predetermined normal information into the detection information storage unit 42, and updates the detection information stored in the detection information storage unit 42. The operation control unit 43 also transmits the safety judgment result and the detection information read from the detection information storage unit 42 to the monitoring device 50. The operation control unit 43 instructs the notification unit 44 to notify information including the occurrence of a fire in the building and an abnormality in the elevator 1.

The notification unit 44 notifies information including the occurrence of a fire in the building and an abnormality in the elevator 1 based on an instruction from the operation control unit 43. Such information is displayed on a display panel 31 in the car 2, for example, to inform passengers of the condition of the building, or to inform rescuers that the car 2 is operating in an inspection run or a fire run. The notification unit 44 may be a speaker provided in the car 2 or the building, and may notify information by sound or sound an alarm. The notification unit 44 may be a red light to visually notify the occurrence of an abnormality.

The monitoring device 50 remotely monitors the operation of the elevator 1. Therefore, the monitoring device 50 is installed in, for example, a monitoring center (not shown) capable of monitoring the status of the plurality of elevator control devices 12. An operator at the monitoring center monitors the operation state of the elevator 1 in each building based on information supplied from the monitoring device 50.

The monitoring device 50 includes a monitoring control unit 51, a display unit 52, an input unit 53, a terminal notification unit 54, and an information storage unit 55.

The monitoring control unit 51 collects the operation information of the elevator 1 and the judgment result of the safety from the elevator control device 12. As described above, the monitoring device 50 can collect the operation information of the car 2 from the plurality of elevator control devices 12. Therefore, when receiving the notification of the start of the inspection operation from the elevator control device 12 installed in the building in which the fire has occurred, the monitoring control unit 51 instructs the elevator control device 12 to transmit the result of the safety judgment. Then, the monitoring control unit 51 receives the result of the safety determination from the elevator control device 12. The monitoring control unit 51 can collect the result of the safety determination from the elevator control device 12, and can collect detection information of each floor in addition to this.

The display unit 52 and the input unit 53 are configured by, for example, a monitoring terminal installed in a monitoring center. The display unit 52 displays the operation status of each elevator 1. The operator can instruct the rescuer terminal 60 to output the detection information collected from the elevator control device 12 through the input unit 53. The contents instructed from the input unit 53 are input to the monitoring control unit 51. Then, the monitoring control unit 51 instructs the terminal notification unit 54 to output the detection information.

The terminal notification unit 54 notifies the rescuer terminal 60 of the result of the determination of the safety of each floor. At this time, the terminal notification unit 54 may notify the rescuer terminal 60 of the result of the determination of safety and the detection information of each floor based on the instruction from the monitoring control unit 51.

The information storage unit 55 stores the operation information, detection information, and the like of each elevator 1 received from each elevator control device 12.

The rescuer terminal 60 is a terminal that a rescuer holds and uses, and can acquire a result of determining the safety of the elevator 1 installed in the building from the monitoring device 50. The rescuer terminal 60 may be installed inside a fire truck or the like on which rescuers stand by. The result of the safety judgment notified from the monitoring device 50 is displayed on a display unit (not shown) of the rescuer terminal 60. Further, on the display unit of the rescuer terminal 60, information on the address of the building where the fire has occurred, information on the elevator 1 that can be operated in the fire-fighting operation mode, detection information collected on the floor on which the safety determination has been made, and the like may be displayed. The rescuer can confirm the display contents of the rescuer terminal 60, know the fire source floor of the elevator 1, the presence or absence of abnormality of each floor, and the like, and safely perform rescue activities.

Next, the contents of the detection information storage unit 42 will be described.

Fig. 5 is a table configuration diagram showing an example of the detection information stored in the detection information storage unit 42.

The detection information is configured as a table having fields of floor, temperature, oxygen concentration, image, and abnormality flag.

In the floor field, the number of floors of all floors in the building where the car 2 can travel is stored.

In the temperature field, the temperature measured by the temperature sensor 22 is saved for each floor. Here, the normal information for the specification of the temperature is, for example, "25 ℃. When the temperature is different from 25 ℃ by 10 ℃ or more, it is judged to be abnormal.

In the oxygen concentration field, the oxygen concentration measured by the oxygen concentration sensor 23 is stored for each floor. Here, the predetermined normal information regarding the oxygen concentration is, for example, "21%". When the oxygen concentration differs from 20% by 3% or more, it is judged to be abnormal.

In the image field, information is stored that the operation control unit 43 analyzes the image captured by the in-car camera 21 and determines whether or not there is an abnormality in the captured location. If the floor is a floor where there is no abnormality, "there is no abnormality" because there is no smoke or the like, and if the floor is a floor where there is an abnormality such as being full of smoke or the like, "full of smoke" is stored as the content of the abnormality. In addition, regarding "no abnormality", the content of the abnormality, a symbol classified in advance may be saved in the image field. In addition, the captured image itself may be stored in the image field.

In the abnormality flag field, an abnormality flag indicating whether or not there is an abnormality determined by the operation control unit 43 for each floor is stored. The operation control unit 43 sets the abnormality flag to OFF for the floor determined as "no abnormality". ON the other hand, the operation control unit 43 turns ON the abnormality flag for the floor ON which it is determined that some kind of abnormality has occurred.

In this way, the operation control unit 43 determines that the k floor is a fire source floor or a floor where an abnormality has occurred based ON the detection information of the k floor where the temperature is 50 ℃, the oxygen concentration is 15%, the image is "full of smoke", and the abnormality flag is ON. Then, for the rescuer terminal 60, only the detection information of the floor whose abnormality flag is set to ON may be provided. The detection information may be added with time information of the time point at which the in-car sensor 20 detects at each floor. Therefore, the rescuer can determine how long the time of entry into the building has elapsed from the time of detection in the past.

Next, a hardware configuration of the computer 70 of each device constituting the elevator control system 100 will be described.

Fig. 6 is a block diagram showing an example of the hardware configuration of the computer 70. The computer 70 is an example of hardware that functions as a computer operable as the elevator control device 12 or the monitoring device 50.

The computer 70 has a cpu (central Processing unit)71, a rom (read Only memory)72, a ram (random Access memory)73, a nonvolatile memory 75, and a network interface 76, which are connected to a bus 74.

The CPU71 reads program codes of software that realizes the functions of the present embodiment from the ROM72, loads the program codes into the RAM73, and executes the program codes. Variables, parameters, and the like generated during the arithmetic processing of the CPU71 are temporarily written into the RAM73, and are appropriately read by the CPU 71. However, MPU (micro Processing Unit) may be used instead of the CPU 71. The functions of the operation mode changing unit 41 and the operation control unit 43 are realized by the CPU71 configured in the elevator control apparatus 12. The functions of the monitoring control unit 51 and the terminal notification unit 54 are realized by the CPU71 configured in the monitoring device 50.

As the nonvolatile storage 75, for example, an hdd (hard Disk drive), an ssd (solid State drive), a flexible Disk, an optical Disk, a magneto-optical Disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory, or the like is used. In the nonvolatile memory 75, programs for causing the computer 70 to function are recorded in addition to the os (operating system) and various parameters. The ROM72 and the nonvolatile memory 75 store programs and data necessary for the operation of the CPU71, and are used as an example of a computer-readable non-transitory recording medium storing programs to be executed by the computer 70. For example, the detection information storage unit 42 of the elevator control device 12 and the information storage unit 55 of the monitoring device 50 are configured by a nonvolatile memory 75.

As the network Interface 76, for example, NIC (network Interface card) or the like is used, and various data can be transmitted and received between devices via lan (local Area network) connected to a terminal of the NIC, a dedicated line, or the like. The elevator control device 12 is provided with a network interface 76 that inputs detection information from the in-car sensor 20 and transmits the detection information and the determination result from the operation control unit 43 to the monitoring device 50. The monitoring device 50 is provided with a network interface 76 that receives the detection information and the determination result from the elevator control device 12 and transmits the detection information and the determination result from the terminal notification unit 54 to the rescuer terminal 60.

Next, a control process of the elevator control device 12 will be described.

Fig. 7 is a flowchart showing an example of a process in which the elevator control device 12 controls the operation of the car 2. Further, it is assumed that the rescuer has not yet reached the building at the start of the present process.

First, when a fire breaks out in the building, the elevator control device 12 is notified of the fire (S1). When the occurrence of a fire is notified, the operation mode changing unit 41 changes the operation mode, which was in the normal operation mode or the maintenance operation mode, to the inspection operation mode. The operation control unit 43 starts the inspection operation to confirm the status of each floor (S2).

When the operation mode is changed to the inspection operation mode, the operation control unit 43 repeats the process of registering a floor higher than the floor at which the car 2 stops as a destination floor, causing the car 2 to travel, opening the door of the car 2, and collecting the detection information until the car 2 reaches a predetermined upper limit floor (for example, the highest limit floor). Therefore, the operation control unit 43 after the start of the inspection operation automatically registers a floor higher than the floor at which the car 2 is currently stopped as a destination floor and runs the car 2 (S3). Then, the operation control portion 43 opens the car 2 after the car 2 stops at the registered destination floor (S4).

Next, the operation control unit 43 compares the detection information (temperature, oxygen concentration, and image) input from the in-car sensor 20 with predetermined normal information, and performs safety confirmation of the floor at which the car 2 stops (S5). When the operation control unit 43 determines that the floor at which the car 2 is stopped is safe, the abnormality flag of the detection information stored in the detection information storage unit 42 is kept OFF. ON the other hand, when it is determined that the floor at which the car 2 stops is unsafe, that is, there is an abnormality, the operation control unit 43 sets the abnormality flag by turning the abnormality flag ON.

After that, the operation control unit 43 closes the door of the car 2 (S6). Next, the operation control section 43 determines whether or not the floor at which the car 2 stops is the highest floor (S7). If the floor at which the vehicle has stopped is not the highest floor (no at S7), the operation control unit 43 repeats the processing of steps S3 to S7 until the floor at which the vehicle has stopped becomes the highest floor.

Then, after the car 2 reaches the upper limit floor (highest floor), the operation control unit 43 causes the car 2 to travel to the evacuation floor, and notifies the rescuer terminal 60 of information on the floor determined to have low safety from the terminal notification unit 54. That is, if the floor at which the car 2 stops is the highest floor (yes at S7), the operation control section 43 registers the evacuation floor (normally, floor 1) as the destination floor of the car 2, and causes the car 2 to travel to the evacuation floor (S8). After that, the car 2 arrives at the evacuation floor (S9). Then, the operation control unit 43 transmits the detection information read from the detection information storage unit 42 to the monitoring control unit 51 of the monitoring device 50.

Then, the operation control unit 43 determines whether or not there is a floor to which entry is restricted (hereinafter referred to as a "dangerous floor") after safety confirmation of each floor is performed based on the received detection information (S10). When there is a dangerous floor (yes at S10), the operation control unit 43 notifies the notification unit 44 of the dangerous floor. The notification unit 44 notifies the monitoring device 50, a display panel installed in a hall, and the like of a dangerous floor (S11).

The operation control unit 43 may perform control for traveling the car 2 to the evacuation floor and prohibiting the car 2 from stopping at the floor determined to have low safety (service prohibition) after the car 2 reaches the upper limit floor (highest floor). By this control, even if the car 2 is designed to perform fire fighting operation, the car is not stopped at a floor determined to have low safety.

If there is no dangerous floor (no at S10), or if the rescue workers arrive at the building after the dangerous floor is notified at step S11, the fire fighting operation is performed (S12). Therefore, the operation mode changing unit 41 notifies the rescuer terminal 60 of information on the floor determined to have low safety, and then receives a change to the fire fighting operation mode by the rescuer. As described above, the rescuer can perform the fire fighting operation using the primary fire switch 32a and the secondary fire switch 32 b.

In the elevator control system 100 according to the first embodiment described above, the elevator 1 is monitored in order to confirm the safety of each floor before the arrival of the rescue workers in the event of a disaster such as a fire. Therefore, when the door is opened after the car 2 stops, the state inside the car 2 is confirmed by the in-car sensor 20, and the rescuer is notified of the state, whereby the rescuer can determine whether the elevator can be lowered during the fire fighting operation for each floor.

Here, in the elevator control system 100, during the inspection operation, the car 2 ascends to the highest floor level by level, the door is opened at each floor, and the operation control section 43 performs the safety check of the entrance of each floor based on the detection information detected by the in-car sensor 20. After that, the operation control unit 43 causes the car 2 to travel to the evacuation floor, and then notifies the person in the building of the dangerous floor through the notification unit 44. Therefore, the manager of the building and the like can promptly know the dangerous floor of the building.

The monitoring control unit 51 of the monitoring device 50 also notifies the dangerous floor to the rescuer terminal 60 via the terminal notification unit 54. The information notified to the rescuer terminal 60 in this way is a judgment result obtained by judging safety in advance by the operation control unit 43. Therefore, the rescuer confirms the rescuer terminal 60, and can know which floor is safe or dangerous and perform a fire fighting operation to perform a rescue activity even if the rescuer itself does not judge the safety of each floor.

The processing in steps S10 and S11 in fig. 7 may be performed by the monitoring device 50. In this case, the monitoring control unit 51 of the monitoring device 50 receives the detection information from the operation control unit 43 after the process of step S9. Then, the monitoring control unit 51 performs safety check on each floor based on the received detection information, and determines whether there is a dangerous floor (S10). When there is a dangerous floor (yes at S10), the monitoring control unit 51 outputs information indicating the dangerous floor to the terminal notification unit 54. The terminal notification unit 54 notifies the rescuer terminal 60 of the information via the network N. Since the dangerous floor is displayed on the rescuer terminal 60, the rescuer can safely perform the rescue activity.

[ second embodiment ]

Next, an elevator control system according to a second embodiment of the present invention will be described. In the present embodiment, a configuration is adopted in which safety confirmation of each floor is performed by a robot that can move autonomously.

Fig. 8 is an overall configuration diagram of the elevator 1. The situation of the building in which the elevator 1 is installed is the same as the building shown in fig. 1. However, robot 80 is waiting at floor 1 of the building.

The robot 80 can autonomously move. In general, the robot 80 functions as a navigation robot that navigates people visiting in a building. When an abnormality such as a fire occurs in the building, the robot 80 autonomously moves to ride the car 2 and moves together with the car 2 in the inspection operation. When the car 2 traveling in the inspection operation mode stops and the door is opened after the car 2 has been mounted on the robot 80, the detection information obtained by the robot sensor 90 detecting the state outside the car 2 can be transmitted to the operation control unit 43. The robot 80 leaves the car 2 at the floor where the car 2 stops, makes a round at the floor, and then gets on the car 2 again. Then, the elevator control device 12 can be notified of the detailed status (e.g., detection information) of each floor.

Next, various sensors configured in the robot 80 will be described.

Fig. 9 is a diagram showing an example of the structure of the robot 80 and the interior of the car 2. Fig. 9 shows a state of the car 2 stopping at 1 floor (evacuation floor) as viewed from the front width direction.

The robot 80 includes a robot sensor 90 as an example of a detection unit that detects detection information required for rescue activity for each floor on which the car 2 travels. The robot sensor 90 has a robot camera 81, a temperature sensor 82, an oxygen concentration sensor 83, a human body sensor 84, and a wireless communication unit 85. The robot 80 serves as a sensor capable of detecting the conditions of the car 2 and the hall and outputting detection information to the elevator control device 12.

The robot camera 81 is an example of a sensor attached to the head of the robot 80 and outputting an image captured at a place where the robot 80 moves. The broken line in the figure shows the shooting range of the robot camera 81. Further, the robot 80 can move at any place in the floor by rotating wheels driven by an internal motor or the like. Therefore, the image captured by the robot camera 81 includes information indicating not only the inside and the entrance of the car 2 but also the state of the place where the robot 80 can move on the floor where the car 2 stops.

The temperature sensor 82 is an example of a sensor that measures the temperature of the place where the robot 80 moves and outputs temperature information. Therefore, the temperature sensor 82 can detect the temperature inside the car 2 and the temperature of the place to which the robot 80 moves. The temperature sensor 82 outputs the detected temperature as detection information.

The oxygen concentration sensor 83 is an example of a sensor that measures the oxygen concentration at the location where the robot 80 moves and outputs oxygen concentration information. Therefore, the oxygen concentration sensor 83 can detect the oxygen concentration in the car 2 and the oxygen concentration at the location where the robot 80 moves. The oxygen concentration sensor 83 outputs the detected oxygen concentration as detection information.

The human body sensor 84 is an example of a sensor that detects infrared rays or the like emitted from a person in danger located at a place where the robot 80 moves and outputs human body detection information. The human body sensor 84 outputs human body detection information as detection information.

The wireless communication unit 85 can perform wireless communication with the wireless communication unit 24 provided in the car 2. The robot 80 wirelessly transmits the detection information via the wireless communication unit 85.

The robot sensor 90 may include at least one of the robot camera 81, the temperature sensor 82, the oxygen concentration sensor 83, and the human body sensor 84. Then, the detection information output by the robot 80 to the elevator control device 12 includes at least one of temperature information, oxygen concentration information, an image, and human body detection information output from the robot sensor 90.

There are cases where a person located on a floor is shown in an image captured by the robot camera 81. If the person can move by himself, the robot 80 instructs the person to board the car 2 and escape to the evacuation floor together with the person. However, if the person cannot move by himself or herself, the robot 80 notifies the elevator control device 12 that there is a person who cannot move by himself or herself because rescue is required.

The car 2 is provided with an in-car operation panel 2c, a switch box 2d, an in-car camera 21, and a wireless communication unit 24.

The in-car operation panel 2c, the switch box 2d, and the in-car camera 21 are the same as those described in the first embodiment. On the display panel 31 (see fig. 3) of the in-car operation panel 2c, the floor determined to have an abnormality, the number of remaining disaster victims on each floor, and the like are displayed.

The wireless communication unit 24 wirelessly communicates with the robot 80 riding on the car 2. Then, the wireless communication unit 24 outputs the detection information received from the robot 80 to the elevator control device 12. The wireless communication unit 24 can transmit information on a movable place in each floor to the robot 80. Robot 80 can move on each floor based on the information of the movable place received from wireless communication unit 24. The wireless communication unit 24 may be provided not only in the car 2 but also in a floor.

The car 2 may be provided with the temperature sensor 22 and the oxygen concentration sensor 23 of the first embodiment, and the car sensor 20 may be configured together with the car camera 21.

Next, a description will be given of a configuration example of an elevator control system for remotely monitoring the elevator 1.

Fig. 10 is a block diagram showing a configuration example of the elevator control system 100A. The elevator control system 100A has substantially the same configuration as the elevator control system 100 of the first embodiment. However, the elevator control system 100A includes the robot 80 and the wireless communication unit 24.

The elevator control device 12 also includes a detection information storage unit 42A in addition to the operation mode changing unit 41, the operation control unit 43, and the notification unit 44 of the first embodiment. The contents of the detection information storage unit 42A will be described with reference to fig. 11.

Fig. 11 is a table configuration diagram showing an example of the detection information stored in the detection information storage unit 42A.

The detection information is configured as a table including fields of a floor, a temperature, an oxygen concentration, an image, the number of remaining persons suffering from a disaster, and an abnormality flag. The floor, temperature, oxygen concentration, image, and abnormality flag have the same contents as those of the detection information of the first embodiment.

In the number of remaining persons, the number of persons who have not been evacuated in each floor is stored as the number of remaining persons. For example, since the k floors as fire source floors are filled with smoke, 2 remaining persons are reflected in the image. Then, the number of remaining disaster victims counted from the images captured on the k-layer is saved to "2", for example. In addition, when there are persons suffering from a disaster in m layers above the k layer that have not been evacuated, the number of 1 remaining persons suffering from a disaster, which is counted from the images captured in the m layers, is stored as "1", for example.

The abnormality flag of the floor ON which the image determined that the abnormality has occurred is set to ON. Further, the abnormality flag is also turned ON for the floor where the retention of the disaster-stricken person is found. Therefore, the rescuer can determine to go to the floor where the abnormality flag is ON and rescue the remaining disaster-stricken with priority.

Next, a control process of the elevator control device 12 according to the second embodiment will be described.

Fig. 12 and 13 are flowcharts showing an example of processing in which the elevator control device 12 controls the operation of the car 2.

First, when a fire breaks out in the building, the elevator control device 12 is notified of the fire (S21). The elevator control device 12 transmits an instruction for the inspection operation to the robot 80 via the wireless communication unit 24. The robot 80 moves to the elevator lobby of floor 1 (evacuation floor) (S22).

When the car 2 reaches floor 1, the robot 80 stands by until the passenger leaves the car 2. When all the passengers leave the car 2, the robot 80 boards the car 2 (S23). As shown in steps S3 and S4 of fig. 7, during the inspection operation, the operation control unit 43 registers the higher floor as the destination floor, and after closing the door of the car 2, the car is driven (S24), and after stopping at the higher floor, the door is opened (S25).

Next, the robot 80 performs safety check in the hall while keeping the car 2 on board. The safety confirmation at this time is performed by collecting the temperature, oxygen concentration, and image in the hall by each sensor of the robot 80. The temperature, oxygen concentration, and image collected by each sensor of the robot 80 are output to the operation control unit 43 via the wireless communication unit 24.

The operation control unit 43 performs safety check based on information such as temperature, oxygen concentration, and image input from the wireless communication unit 24. When it is determined that the floor at which the car 2 is parked is unsafe, that is, there is an abnormality, the operation control unit 43 sets an abnormality flag by turning ON the abnormality flag (S26).

Further, the operation control unit 43 determines whether or not there is a disaster-stricken person in the entrance hall (S27). The presence or absence of a person suffering from a disaster is determined by the operation control unit 43 based on human body detection information collected from the robot 80, for example. When a person suffering from a disaster is present in the lobby (yes at S27), the person suffering from a disaster needs to be evacuated as soon as possible. Then, the process proceeds to step S30 in fig. 13 connected to the connector a. In this process, when the disaster-stricken person is found when the car 2 is stopped and the door is opened, the robot 80 prompts the disaster-stricken person to board the car 2 and boards the car 2 together with the disaster-stricken person. Then, the operation control unit 43 causes the car 2 on which the disaster-stricken person and the robot 80 ride to travel to the evacuation floor (S30).

On the other hand, when there is no disaster-stricken person in the hall (no in S27), the operation control unit 43 closes the car 2 (S28). Next, the operation control unit 43 determines whether or not the floor to which the car is parked is the highest floor (S29). If the floor to which the vehicle is stopped is not the highest floor (no at S29), the operation control unit 43 repeats the processing of steps S24 to S29 until the floor to which the vehicle is stopped becomes the highest floor.

On the other hand, if the floor at which the car 2 stops is the highest floor (yes at S29), the process proceeds to step S31 of fig. 13 connected to the connector B, and the operation control unit 43 opens the door of the car 2. The robot 80 descends and moves within the floor where the car 2 stops, and confirms whether or not there is a disaster-stricken person in the floor (S31).

Next, the robot 80 determines whether or not there is a disaster-stricken person in the floor (S32). If there is no disaster-stricken person (no at S32), the robot 80 returns to the entrance hall and gets on the car 2 (S34). The robot 80 after returning to the car 2 outputs the temperature, oxygen concentration, and image of the floor where it is determined that the disaster-stricken person is present to the operation control unit 43 via the wireless communication unit 24.

On the other hand, when there is a disaster-stricken person (yes at S32), the robot 80 determines whether or not the disaster-stricken person can move (S33). For this determination, for example, when the person in trouble presses a button or the like displayed on a touch panel provided to the robot 80, the robot 80 may determine that the person in trouble is able to move.

Then, if the disaster-stricken person can move (yes at S33), the process proceeds to step S30, and the robot 80 takes the car 2 together with the disaster-stricken person and proceeds to the evacuation floor to evacuate. At this time, the operation control unit 43 is notified from the robot 80 that the robot 80 has mounted on the car 2 together with the disaster-stricken person. Then, the operation control unit 43 registers the evacuation floor as the destination floor and causes the car 2 to travel.

On the other hand, when the robot 80 determines that the disaster-stricken person cannot move (no at S33), the robot 80 returns to the entrance and gets on the car 2 (S34). Then, the robot 80 transmits the floor and the place where the immovable disaster-stricken person stays to the operation control unit 43.

Next, the operation control section 43 determines whether or not the floor at which the car 2 currently stops is the lowest floor (S35). If the floor at which the car 2 is currently stopped is not the lowest floor (floor 1) (no at S35), the operation control section 43 automatically registers the floor lower than the floor at which the car 2 is currently stopped as the destination floor, and after closing the door of the car 2, the car is driven (S36), and the process returns to step S31 to open the door of the car 2.

In this way, after the car 2 reaches the upper limit floor, the operation control section 43 repeats the processing of steps S31 to S36 until the car 2 reaches the evacuation floor. In this process, the robot 80 moves among floors for each floor where the car 2 stops and the door is opened, and searches for a disaster-stricken person.

On the other hand, if the floor to which the vehicle is parked is the lowest floor (yes at S35), the operation control unit 43 performs safety check to determine whether or not there is a disaster-stricken person collected from the robot 80. At this time, the operation control unit 43 writes the floor where the immovable disaster-stricken person stays in the detection information storage unit 42 as the priority rescue floor. Then, the operation control unit 43 transmits the result of the judgment of the safety of each floor and the priority rescue floor to the monitoring device 50. At this time, the operation control unit 43 may transmit the detection information collected on each floor to the monitoring device 50.

The monitoring control unit 51 of the monitoring device 50 determines whether or not there are remaining persons suffering from a disaster in the priority rescue floors based on the priority rescue floors and the number of remaining persons suffering from a disaster received from the elevator control device 12 (S37). When determining that there is a disaster-stricken person remaining (yes at S37), the monitoring control unit 51 notifies the rescue worker terminal 60 of the floor where the disaster-stricken person is present as the priority rescue floor (S38).

After notifying the rescuer terminal 60 in step S38 or after the robot 80 determines that there is no resident victim (no in S37), the operation control unit 43 performs safety confirmation based on information such as temperature, oxygen concentration, and image input from the wireless communication unit 24. Then, the operation control unit 43 determines whether or not there is a floor at which the entrance is dangerous after the safety confirmation based on the detection information read from the detection information storage unit 42A (S39).

If there is a dangerous floor (yes at S39), the operation control unit 43 sets the abnormality flag by turning the abnormality flag ON, and does not allow the service so that the car 2 does not come to a dangerous floor (S40). Further, the operation control unit 43 transmits the result of the safety judgment to the monitoring device 50. The monitoring control unit 51 of the monitoring device 50 notifies the rescuer terminal 60 of the result of the safety judgment through the terminal notification unit 54.

If there is no dangerous floor (no at S39), or if the rescue workers arrive at the building after the service of the dangerous floor is not permitted at step S40, the fire fighting operation is performed (S41). As described above, the rescuer can perform the fire fighting operation using the primary fire switch 32a and the secondary fire switch 32 b.

The elevator control system 100A according to the second embodiment described above monitors the elevator 1 using the robot 80 in order to confirm the safety of each floor before the arrival of the rescue workers in the event of a fire. Therefore, when the door is opened after the car 2 stops, the robot 80 confirms the state inside the car 2 and notifies the rescuer that it is possible to determine whether or not the elevator can be lowered during the fire fighting operation.

Then, the robot 80 gets on the car 2, and every time the car 2 stops at each floor, the robot 80 detects the situation around the entrance and transmits the detected situation as detection information. Therefore, the robot 80 can safely know the situation around the entrance hall. Then, the rescue worker is informed of the result of the determination of the safety of each floor by the inspection operation performed before the rescue worker arrives at the building, so that the work during the fire fighting operation can be performed safely. In addition, when there is a disaster-stricken person around the entrance, the robot 80 can transfer the disaster-stricken person to the evacuation floor as soon as possible after reminding the disaster-stricken person to board the car 2.

Further, by applying the robot 80 instead of the in-car sensor 20, the elevator control device 12 can know the status of each floor without adding unnecessary equipment (various sensors, cameras, and the like) in the car or the entrance. Therefore, the cost for configuring the elevator control system 100A can be reduced.

In addition, if the in-car sensor 20 mounted on the car 2 is out of order, the car 2 must be stopped. However, if the robot sensor 90 attached to the robot 80 is in a bad condition, it is possible to deal with the situation where only the robot 80 is repaired, and there is no inconvenience to passengers using the elevator 1.

When there is no disaster-stricken person around the entrance, the car 2 moves from the highest floor to the lower floors in sequence, and the robot 80 descends and moves within each floor. The robot 80 detects whether there is a remaining disaster-stricken person in the floor to which the elevator is descending. Since the monitoring device 50 is notified of the floor where the disaster-stricken person is present as the priority rescue floor and the rescue person terminal 60 is also notified of the priority rescue floor, the rescue person can rescue the disaster-stricken person as soon as possible. Therefore, even if the robot 80 cannot transport the remaining disaster-stricken person, the rescue of the remaining disaster-stricken person can be speeded up.

Further, the rescue worker terminal 60 displays the situation of the remaining disaster-stricken person, which is obtained by the robot 80 performing the safety confirmation. Therefore, the rescue worker can confirm the situation of the remaining disaster-stricken person before going to the floor where the remaining disaster-stricken person is located, and thus it is easy to prepare in advance to rescue the equipment necessary for the remaining disaster-stricken person.

In the second embodiment, since the robot 80 can move within the floor, the temperature and the oxygen concentration may locally change. Therefore, a code such as a zone number indicating a place where the temperature or the oxygen concentration is increased, where the disaster-stricken person is present, or an area number added to each place can be added to the record for each floor. Then, the detection information may include a code together with the information of each floor. The rescuer confirms the detection information through the rescuer terminal 60, and thus can know which place has high safety and where there are many remaining disaster victims and go to rescue.

In step S40 of fig. 13, if the floor on which the disaster-stricken person is not present is a floor on which the operation control unit 43 determines that inspection is unnecessary, the terminal notification unit 54 may notify the emergency call terminal 60 of the floor on which inspection is unnecessary. The rescue worker can perform the rescue operation without assigning extra persons to the floor by knowing the floor which does not need to be checked in advance.

[ modified examples ]

In each of the above embodiments, the operation control unit 43 writes the detection information into the detection information storage unit 42, and then transmits the detection information to the monitoring device 50 at a predetermined timing. However, the in-car sensor 20 of the first embodiment may transmit the detection information to the monitoring device 50 at the timing when the detection information is detected. Detection information detected by the robot sensor 90 of the robot 80 according to the second embodiment may be transmitted to the monitoring device 50 at a timing when the robot 80 gets on the car 2 or a timing when the car 2 stops at the highest floor or the lowest floor.

Further, the disaster occurring in the building in each of the above embodiments is not limited to a fire. For example, the elevator control systems 100 and 100A may monitor the disaster situation of the building for each floor of the earthquake, electric leakage, and flood elevator 1 and transmit the result of the safety determination to the rescuer terminal 60.

In addition, the elevator 1 according to each of the above embodiments can be used by a general passenger in a normal state. However, an elevator which can be taken by general passengers may be separately installed in a building, and the elevator 1 may be used as an emergency elevator which cannot be taken by general passengers at normal times.

The present invention is not limited to the above embodiments, and various other application examples and modifications can be adopted without departing from the spirit of the present invention described in the scope of claims.

For example, the above embodiments have been described in detail and specifically with respect to the configurations of the apparatus and the system for easy understanding of the present invention, and are not limited to the embodiments having all the configurations described. In addition, a part of the structure of the embodiment described here can be replaced with the structure of another embodiment, and the structure of another embodiment can be added to the structure of a certain embodiment. In addition, other configurations can be added, deleted, and replaced for a part of the configurations of the embodiments.

In addition, the control lines and the information lines are shown to be considered necessary for the description, and not necessarily all the control lines and the information lines on the product are shown. In practice it can also be considered that almost all structures are interconnected.
