- the brake control device 18 determines the propriety of the hoisting machine rescue operation, the brake rescue operation, and the remote rescue operation based on the determination result of whether the function of the sensor group 29 is normal. For example, when it is not confirmed that the door open / close detection sensor 22 is normal, it is determined that the hoisting machine rescue operation and the brake rescue operation which are implemented by the judgment of only the brake control device 18 are not possible. If it is not confirmed that the encoders 13 and 27 are normal, it is determined that the brake rescue operation is not possible.

- FIG. 3 is a flow chart showing the operation of the brake control device 18 of FIG.
- the brake control device 18 confirms the state of the safety circuit 30 at a predetermined cycle to confirm whether or not the rescue operation is necessary (step S2).
- step S1 the brake control device 18 confirms the state of the safety circuit 30 at a predetermined cycle to confirm whether or not the rescue operation is necessary.
- step S3 it is checked whether the hoisting machine rescue operation is possible based on the signal from the sensor group 29 and the state of the safety circuit 30 (step S3). ).
- the hoisting machine rescue Judge that driving is not possible.
- the safety circuit 30 is shut off, and it is determined that the hoisting machine rescue operation is not possible based on this state.
- the brake control device 18 drives the hoisting machine motor 6 at a low speed via the operation control device 16 to carry out the hoisting machine rescue operation (Ste S4).
- the confirmation (step S5) as to whether or not the rescue is completed and the confirmation (step S3) as to whether or not the hoisting machine rescue operation is possible are repeatedly performed in a predetermined cycle.
- the confirmation as to whether the rescue is completed is performed based on the signal from the sensor group 29 and the state of the safety circuit 30. Specifically, for example, if it is detected that the car door is opened based on the signal from the door open / close detection sensor 22, it is determined that the rescue operation is completed. However, in order to make such a determination, it is necessary to make the car door openable only when the car 1 is located on the landing floor.
- the rescue operation is not completed even after the preset time, even if it is determined that the hoist rescue operation is possible, the hoist rescue operation is properly performed for some reason. There is no possibility. Therefore, in such a case, it may be set to change the determination that the hoisting machine rescue operation is not possible.
- the brake control device 18 determines whether or not normal operation is possible (step S6).
- the determination of normal operation is made based on the signal from the sensor group 29 and the state of the safety circuit 30. Specifically, for example, all the signals from the sensor group 29 are signals indicating the normal state, and it is determined that the normal operation is possible if the safety circuit 30 is not cut off.
- step S1 If it is determined that the normal operation is possible, the normal operation is resumed as it is (step S1). On the other hand, when it is determined that the normal operation is not possible, the maintenance center is notified and stands by (step S7). After that, the recovery work is performed by a specialized worker, and after the safety is confirmed, the normal operation is resumed.
- step S3 when it is determined that the hoisting machine rescue operation is not possible in the hoisting machine rescue operation determination (step S3), the brake control device 18 confirms that the car 1 is stopped ( Step S8) The current supply to the brake coils 10a and 10b is shut off to hold the car 1 in a stationary state (step S9). Further, the shutoff switch 17 is opened to shut off the power supply to the hoist motor 6 (step S10).
- the reason why the stop of the car 1 is confirmed before the current supply to the brake coils 10a and 10b is interrupted is that the brake coil 10a is running while the car 1 is traveling when the rescue command by the operation control device 16 is incorrect. , 10b to prevent the car 1 from being unnecessarily stopped suddenly.
- a method of confirming the stop of the car 1 there is a method of confirming based on signals from the hoisting machine encoder 13 and the governor encoder 27. That is, when the pulse of the signal from the encoders 13 and 27 does not change or when the rotational speed converted from the pulse is equal to or less than a predetermined value, it can be determined that the car 1 is stopped. When it is determined that the acceleration of the car 1 is 0 for a predetermined time or more by the signal from the accelerometer 21, it can be determined that the car 1 is stopped.
- step S9 the car 1 is held stationary (step S9), so it is performed before the cutoff switch 17 is opened. That is, when the car 1 is stopped by the driving force of the hoist motor 6, if the shutoff switch 17 is first opened, the car 1 moves due to the unbalance between the car 1 and the counterweight 2, so the brake The energization of the coils 10a and 10b is shut off to maintain the state of the car 1.
- the brake control device 18 After opening the shutoff switch 17, the brake control device 18 notifies the maintenance center that the elevator device is in a state requiring a recovery operation (step S11). In addition, although the brake control device 18 determines that the rescue operation is unnecessary, when the operation control device 16 determines that the rescue operation is necessary, it is possible that the determination may not be consistent. Report to the maintenance center. Specifically, for example, the brake control device 18 confirms that the car 1 is stopped at the door openable position and the car door is open, and the brake control device 18 determines that the rescue operation is unnecessary. In the case where the rescue command from the operation control device 16 is transmitted to the brake control device 18 despite the problem, the failure is notified to the maintenance center.
- the brake control device 18 determines whether or not the brake rescue operation is possible (step S12). Specifically, a voltage is applied to the brake coils 10a and 10b, and current conduction to the brake coils 10a and 10b can be confirmed by the current sensors 12a and 12b, and opening and closing operations of the brake linings 9a and 9b are confirmed by the brake switches 11a and 11b. If it is confirmed that the weight difference between the car 1 and the counterweight 2 is large enough to move the car 1 from the signal from the weighing device 20, it is determined that the brake rescue operation is possible. Do.
- whether or not the weight difference between the car 1 and the counterweight 2 is a sufficient magnitude depends on whether the car 1 side of the main rope 3 or the control cable (not shown) according to the stop position of the car 1 It is judged including the weight difference with the combined weight 2 side. Then, if the weight difference is larger than the resistance due to friction or movement loss when moving the car 1, it is determined that the weight difference is sufficient.
- the brake control device 18 also determines whether the state of the system including the sensor group 29 is in a state where the brake rescue operation can be performed by comparing the multiplexed same kind of state signals.
- the brake rescue operation is performed.
- the state of the car 1 is confirmed (step S13).
- the state confirmation of the car 1 the confirmation of the presence or absence of the car 1 at the floor position, the detection of the car speed, and the like are performed.
- step S14 the voltage applied to the brake coils 10a and 10b is adjusted, and the brake torque is adjusted so that the car speed follows the preset target speed (step S14).
- a method of targeting a change in car position that is, a control method of following a change in position may be applied.
- step S15 based on the detection result of the presence or absence of the car 1 at the floor position detected in advance, it is checked whether the car 1 is in the door openable position (step S15). If the door openable position has not been reached, the process returns to the judgment as to whether or not the brake rescue operation is performed (step S12). During the brake rescue operation, the operations of steps S12 to S15 are repeated in a predetermined cycle.
- step S16 When the car 1 reaches the door openable position, the stationary state of the car 1 is maintained (step S16), and the car door and the landing door are opened and waited (step S17). This allows passengers to get off the landing floor. After that, the recovery work is performed by a specialized worker, and after the safety is confirmed, the normal operation is resumed.
- the brake control device 18 can confirm that the rescue operation has been completed, based on the signal from the operation control device 16 that transmits the end of control and the signal from the sensor group 29. For example, by detecting that the car door is opened based on the signal from the door open / close detection sensor 22, it can be determined that the rescue operation is completed. However, in order to make such a determination, it is necessary to make the car door openable only when the car 1 is located on the landing floor.
- the brake control device 18 may notify the maintenance center via the communication device 19. If, on the other hand, there is a command for remote rescue operation from the maintenance center, the brake rescue operation may be interrupted, and the process may shift to determination of availability for remote rescue operation (step S18).
- step S18 it is determined whether the remote rescue operation is possible.
- the remote rescue Judge that driving is possible.
- the passenger in the car 1 can talk with the interphone device using the intercom device, or the image of the camera in the car 1 or the platform
- the maintenance center it is possible to remotely move the car 1 to the landing floor and rescue the passengers while securing the safety of the passengers.
- step S19 If it is determined that the remote rescue operation is possible, a notification to that effect is sent to the maintenance center (step S19). Thereafter, the remote rescue operation is performed according to the remote control from the maintenance center (step S20). Even when remote rescue operation is performed, a recovery operation is performed by a specialized worker after the rescue operation is completed, and normal operation is resumed after safety is confirmed.
- step S21 when it is determined that the remote rescue operation is not possible, a notification to that effect is sent to the maintenance center to stand by (step S21). In this case, the rescue and recovery work of the passenger is performed by the specialized worker, and after the safety is confirmed, the normal operation is resumed.
- the brake control device 18 compares the multiplexed similar signals received from the sensors with each other. It is determined whether the sensor is functioning properly and the possibility of brake rescue operation is determined based on the determination result, so that malfunction due to sensor failure or false detection can be prevented, and rescue is performed more reliably and quickly. You can drive. That is, at the time of rescue operation, it is possible to prevent the car 1 from passing through the door zone of the end floor and entering the end of the hoistway or the car speed reaching the overspeed.
- the brake control unit 18 receives signals from the sensor group 29 and also supplies electric power independently from the operation control unit 16, even when the operation control unit 16 can not move the car 1, Brake rescue operation can be performed, and passengers can be rescued more reliably and promptly.

And shut off the power supply to the hoist motor 6. Therefore, it is more reliable that the car 1 is suddenly stopped unnecessarily or the car 1 moves due to the imbalance between the car 1 and the counterweight 2. Can be prevented.
- the brake control device 18 determines that the brake rescue operation is not possible, the fact is notified to the remote maintenance center, so that when a large number of elevator apparatuses are simultaneously stopped due to an earthquake etc., it is automatically performed.
- the elevator apparatus which can not carry out the rescue operation can be easily grasped at the maintenance center, and the passengers can be rescued promptly.
- the brake control device 18 can move the car 1 by controlling the braking force of the brake device 8 according to a command from the maintenance center, depending on the state of the elevator device, specialized work may be performed.
