First, the overall configuration of the present embodiment will be described with reference to FIGS. 1 and 2 . In FIG. 1 , a building in which an elevator is installed includes a control device 101 that controls the operation of the elevator, a motor 102 that is driven and controlled by the control device 101 , a car 103 that is lifted and lowered by the motor 102 through ropes, and a car 103 that is connected to the car 103 . Balanced counterweight 104. The car 103 moves up and down in the elevator shaft along a rail (not shown) provided in the elevator shaft. The car 103 is equipped with a load detection device 105 for detecting the load in the car, and detects the load in the car 103 by detecting the sinking of the passenger when entering the car 103 by, for example, a non-contact sensor. The passenger can register the destination floor by operating the operation panel 106 in the car. A baffle plate 108 is installed on the lower part of the car, which is used to fill the gap between the car 103 and the leveling position when the car 103 deviates from the leveling position. The passenger waiting at the boarding place calls the car 103 to go to the boarding floor by operating the boarding place call button 109 .

In addition, an encoder 107 for detecting the position of the car 103 is connected to the motor 102 . The encoder 107 generates a pulse signal in synchronization with the rotation of the motor 102 and outputs the signal to the control device 101 . The control device 101 detects the position of the car 103 by counting the received pulse signals. In addition, the control device 101 is connected to an earthquake sensor 112 capable of detecting shaking when an earthquake occurs, and a receiving unit 113 capable of receiving an emergency reception alert.

The car door 111 installed in the car 103 is opened and closed by a door motor 114 installed in the upper part of the car 103 . On the other hand, the boarding gate 110 installed at the boarding place on each floor of the building is also opened and closed by the operation of the above-mentioned door motor 114 . That is, the car door 111 and the boarding door 110 are provided with door engaging devices 200 facing each other in a plan view. When the car is leveled, the door engaging devices 200 are engaged with each other, and the power of the door motor 114 passes through the door card. The closing device 200 is transmitted to the boarding door 110 to perform the opening and closing operation.

The door engaging device 200 described above is composed of an engaging roller 201 (boarding door engaging unit) and an engaging element 202 (car door engaging unit), the engaging roller 201 being provided on the boarding door 110, and the engaging element 202 being It is installed on the car door 111 so as to protrude toward the boarding position, and is arranged on both sides of the engaging roller 201 when leveling. The engaging rollers 201 and the engaging elements 202 are arranged as shown in FIG. 2A when each layer is leveled. When the door is opened, the car door 111 is opened by the power of the door motor 114 . When the car door 111 is opened, the engaging element 202 and the engaging roller 201 are engaged, and the boarding door 110 is opened ( FIG. 2B ). Also, when the door is closed, the engaging element 202 and the engaging roller 201 are engaged, and the power of the door motor 114 is transmitted to the boarding door 110, and the boarding door 110 is closed.

Next, the configuration of this embodiment will be described with reference to FIG. 3 . The receiving unit 113 is a unit for receiving an emergency earthquake early report issued after an earthquake occurs. The control device 101 is provided with a car state determination unit 301 . The car state determination unit 301 receives a pulse signal synchronized with the rotation of the motor 102 from the encoder 107 , and detects the position of the car 103 . In addition, a signal is received from the load detection device 105, and the presence or absence of a passenger is detected based on the load of the car 103. Furthermore, operation information of the operation panel 106 in the car and the boarding point call button 109 is detected.

This embodiment has: the first regulated operation control unit 302, when the receiving unit 113 receives the emergency earthquake early report and learns that there are passengers in the car 103 through the information of the car state determination unit 301, the car 103 is stopped. On the nearest floor; and the second regulated operation control unit 303 drives the car to a position where the car door 111 and the boarding door 110 do not engage when there is no passenger in the car 103 . The present embodiment is characterized in that it is provided with a door latching avoidance operation control unit (the second controlled operation control means 303 ), and when an emergency earthquake warning is received, the car 103 is moved until the car door 111 and the boarding door 110 are not locked. matching position.

Next, the processing steps of this embodiment will be described with reference to FIG. 4 . The control device 101 first performs the normal operation by the normal operation processing step (S402) after the elevator is powered on and then performs the initial processing step (S401). The control device 101 monitors the receiving unit 113 of the emergency earthquake early report reception status, and if the emergency earthquake early report is not received (No in S403 ), the normal operation processing procedure is continued ( S402 ). When an emergency earthquake early warning is received (YES in S403 ), a controlled operation processing step is implemented in S404 .

Next, the details of the controlled operation processing will be described with reference to FIG. 5 . When an emergency earthquake alert is received, it is necessary to stop the elevator before the earthquake shaking arrives because the earthquake may damage the elevator and prevent it from functioning properly. In this embodiment, when the control device 101 determines that there is a passenger in the car 103, the passenger leaves the car 103 as a priority, and when it determines that there is no passenger in the car 103, it prioritizes preventing the car 103 from being damaged. First, the information on the state of the car is acquired in the process of S501. The information on the state of the car includes, for example, the presence or absence of a car call or registration of a boarding place call, the load in the car, the position of the car, and the running state.

In the step of determining whether the car 103 can travel, if it is determined that the car 103 is traveling (YES in S502 ), it is determined in S503 whether or not a car call is registered. When a car call is registered (YES in S503), it is determined that there is a passenger in the car 103, and in order to give priority to the rescue of the passenger, the process of the first controlled operation control unit 302 is carried out (S504), even if the car 103 stops to the nearest floor to make the passenger Leave car 103.

When the car call is not registered (NO in S503 ), it is driven by the boarding point call, so it is judged that there is no passenger in the car 103 , and in order to give priority to preventing damage to the car 103 , the process of the second regulated operation control unit 303 is implemented. (S506), even if the car 103 is parked at a position where the door is not engaged. In addition, when the car 103 has stopped in S502 (No in S502), when the door has been closed for a predetermined time or longer (Yes in S507), or when the load in the car 103 is less than or equal to a predetermined value (Yes in S508), It is determined that there is no passenger in the car 103, and the process of the second regulated operation control unit 303 is carried out (S506).

When, for example, one minute or more has elapsed since the elevator was not operated after the service, it is determined that there is no passenger in the car 103 . In S507, when the door is closed for a predetermined time or more (No in S507), and when the load in the car 103 is greater than a predetermined value, such as 30 kg, which is considered to be occupied by a person (No in S508), the car 103 may be loaded with a load. Since there is a passenger, the process of the first regulated operation control unit 302 is carried out (S504). After the step (S504) of the first regulated operation control unit 302 and the step (S506) of the second regulated operation control unit 303 are carried out, the elevator enters a resting state.

When an earthquake occurs after receiving the emergency earthquake early warning, and the earthquake sensor 112 is activated due to shaking, or when the elevator detects a failure due to shaking and stops (YES in S510), the machine may have been damaged, so maintenance personnel must implement it. The restoration of the failure state and the confirmation of the operation are performed and the restoration is performed ( S512 ). In addition, if the earthquake sensor 112 is not activated (No in S510), it is determined that the shaking has no effect on the elevator, and after a predetermined time has elapsed (Yes in S511), the elevator automatically resumes normal operation (S512). In S511, taking into account the cessation of shaking and the occurrence of aftershocks, the rest state is continued for, for example, one minute. In addition, when the predetermined time has not elapsed in S511 (No in S511 ) and the maintenance worker has not recovered (No in S513 ), the elevator continues to be in a resting state.

Next, the processing procedure of the first regulated operation control unit 302 and the second regulated operation control unit 303 will be described with reference to FIGS. 6 and 7 . FIG. 6 shows the processing procedure of the first regulated operation control unit 302 for stopping the car 103 to the nearest floor and allowing passengers to leave the car 103, and FIG. 7 shows the second regulated operation control for stopping the car 103 to the position where the door does not engage. The processing steps of unit 303 . When the first supervisory operation control unit 302 is implemented in S504, the nearest floor leveling operation is performed in S601. After reaching the nearest floor, the door is opened and the passengers in the car 103 are reminded to leave (S602).

After a sufficient time has elapsed for the passengers in the car 103 to leave (YES in S603), the door is closed (S604), and the elevator enters a resting state (S605).

On the other hand, when the second regulated operation control unit 303 is implemented in S506, the vehicle travels to the nearest floor (S701), and at this time, when the position where the door above the ground where the boarding place does not engage is detected (YES in S702), the vehicle enters Rest state (S703).

The position where the car 103 is stopped is the position where the door is not engaged, that is, the position where the engagement roller 201 and the engagement element 202 are not engaged. Thereby, it is possible to prevent the engagement roller 201 and the engagement element 202 from being violently collided with each other due to seismic shaking, thereby preventing damage. Under normal circumstances, the position of the door engagement will not change due to the floor. Therefore, based on the output signal of the encoder 107, the car 103 is stopped at a position where the position where the car 103 is detected is a predetermined height from the floor of the boarding place of the closest floor to be moved.

In addition, when the elevator fails to move due to an earthquake, a maintenance worker enters the car 103 and performs restoration work. At this time, in the present embodiment, by setting the parking position of the car 103 on the ground where the car 103 is on board, the operator can easily get into the car 103, and the operability is improved. That is, in the state shown in FIG. 8A in which the car 103 is parked at a position under the floor of the boarding place where the door is not engaged, when a maintenance worker confirms the inside of the car 103, the floor of the car is lower than the boarding place, and it is difficult for the operator to check the interior of the car 103. When entering the car 103, the operability is poor. In the state shown in FIG. 8B in which the door is parked on the floor of the car above the floor of the boarding area and the door is not engaged, the operator can easily enter the car 103 , and not only the operability of the restoration work is improved, but also the use of the shutter 108 Fill up the gap between the boarding point and the car floor, thereby improving safety. Therefore, it is preferable that the parking position of the cage|basket|car 103 is a position where the door on the ground of a boarding place does not engage. In addition, when the time before the arrival of the main shock is included in the received data of the emergency earthquake early warning, the second restricted operation control means 303 may be implemented after the first restricted operation control means 302 if there is a buffer for a predetermined time. The predetermined time is the time required for the car to move to the position where the door is not engaged. At this time, the door operator can be prevented from being damaged due to earthquakes while ensuring the safety of passengers.

As described above, in the present embodiment, the controlled operation control is provided to move the car 103 to a position where the car door 111 and the boarding door 110 do not engage when an emergency earthquake alarm is received, so that damage to the door operator can be prevented. . In addition, in this embodiment, by preventing damage to the door machine, early recovery of the elevator can be achieved during an earthquake. Furthermore, according to this embodiment, the efficiency and safety of the maintenance worker's restoration work can be improved.
