With the advancement of digital electronic technology, the speed and position control of elevators has recently been carried out by detecting pulses generated in response to the movement of the car, detecting the position of the car using these pulses, and using this position signal as a means of controlling the speed and position of elevators. Therefore, a speed command signal is generated, and the speed of the car is controlled using this speed reference signal.
A1 in FIG. 1 shows the speed command signal with the horizontal axis representing time, and A2 in FIG. 2 similarly shows the distance to the scheduled stop floor. However, when the car lands on the floor, it is difficult to accurately land the car on the floor because a position detection error occurs due to the pulses and the position resolution of the speed command signal A1 is insufficient. Therefore, as shown in Figure 3,
A detected object 2 is arranged at a position corresponding to each floor of the hoistway 1, and a second
Deceleration signal (speed command signal near the floor) shown in the figure B
An implantation device that generates this will be installed. That is, the speed of the car 3 is controlled by the speed command signal A2 from the start of running of the car 3 to a point P that is a certain distance before the scheduled stop floor, and then the speed of the car 3 is controlled by switching to the deceleration signal B. The robot stops accurately on the floor.

On the other hand, various considerations have recently been made regarding elevator operation during earthquakes, including measures to be taken when car 3 is running in an express section. An express section is a section where there is no boarding area, and in Figure 3, there are 3
This applies to floors 1 to 15. Car 3 normally passes through this express section without stopping. Within this express section, rescue exits leading to floors are provided on each floor or every few floors. In Figure 3, the rescue exit 5 is provided on the fourth floor. If an earthquake occurs while the car 3 is traveling in the express section, the car 3 is stopped at the rescue exit 5, and the passengers inside the car 3 are rescued from there.

When a travel command is issued, the travel command relay contact 18 is closed, the switching relay 21 is energized, the contacts 21a and 21b are closed, and the contact 21c is opened. The electric motor drive device 22 operates according to the traveling command, and the electric motor 7 rotates, so that the car 3 starts traveling. When car 3 starts running, switching point detection relay contact 19 closes, so (+)-19
The switching relay 21 is held by the circuit -21a-21-(-). Further, as the car 3 runs, the governor wheel 14 rotates and drives the pulse generator 16. The pulse generator 16 generates one pulse every time the car 3 moves by 10 mm, and the speed command generator 17
A speed command signal A2 is generated from the motor 2 and is applied to the electric motor 22 via the contact 21b. On the other hand, as the car 3 travels, the speedometer generator 12 is driven, and a speed signal proportional to the speed of the car 3 is generated. The motor drive device 22 automatically controls the speed of the motor 7 based on the speed command signal A2 and the deviation signal of the speed signal. When the car 3 decides to stop in order to respond to a call on the second floor, the run command relay contact 18 opens. When the car 3 reaches a point P a certain distance in front of the second floor, the switching point detection relay contact 19 opens and the switching relay 2
1 is deenergized, contacts 21a and 21b are opened, and contact 21c is closed. The speed command generating device 17 is now disconnected from the motor drive device 22, and the landing device 4 is connected instead. Therefore, from now on, due to the engagement between the landing device 4 and the detected object 2 on the second floor, the deceleration signal B is generated according to their relative positions.
is emitted. This deceleration signal B is applied to the motor drive device 22 via the contact 21c, thereby controlling the landing speed of the car 3, so that the car 3 accurately lands on the second floor. The same applies to other floors outside the express section.

の速度制御も上述と同様である。
If an earthquake occurs while the car 3 is running outside the express section, the car 3 is stopped at the nearest floor, and the speed control at this time is the same as described above.

If an earthquake occurs while car 3 is running on the express section,
Similarly, the car 3 is stopped at the nearest floor, but if the fourth floor where the rescue exit 5 is located corresponds to the nearest floor, the car 3 is controlled to stop at the fourth floor. When the car 3 decides to stop at the fourth floor, the traveling relay contact 18 is opened, and when it reaches a point P a certain distance before the fourth floor, the switching point detection relay contact 19 is opened. However, since the express section detection relay contact 20 is closed at this time, the switching relay 21 is kept energized, the contact 21b remains closed, and the contact 21c remains open. Therefore, the car 3 decelerates in accordance with the speed command signal A2 and comes to a stop on the fourth floor. The landing error of car 3 at this time is:
It may be larger than when controlled by deceleration signal B, but this is an emergency case of earthquake rescue, and the difference in level between the floor of car 3 and the floor of rescue exit 5 is slightly greater than in normal times. It is not a problem even if this occurs.

In the embodiment, the landing device 4 was installed in the car 3 and the detected object 2 was installed in the hoistway 1, but this was reversed, and the landing device 4 was installed at each floor position of the hoistway 1, and the detected object 2 was installed in the hoistway 1. 2 may be provided in the car 3.

As explained above, the present invention controls the speed of the car using a speed command signal obtained from a pulse emitted in response to the movement of the car, and when the car approaches a floor where it should stop, a When landing the car by switching to the deceleration signal generated from the landing device, when stopping the car at the rescue exit, the car should be controlled only by the speed command signal without switching to the landing device. This is what I did.

これにより、救出口には着床装置又は被検出体

As a result, there is no need to provide a landing device or a detected object at the rescue exit, and the number of devices in the hoistway can be reduced, resulting in a low-cost configuration and reduced maintenance and inspection effort.
