【Example】

Embodiment 1 FIG. The configuration of the first embodiment of the present invention will be described with reference to FIG. FIG. 1 is a diagram showing Embodiment 1 of the present invention. In the drawings, the same reference numerals indicate the same or corresponding parts.

In FIG. 1, 1 is a basket connected to a rope 6, 2 is an interphone in the basket 1, and 3 is a monitoring center 4 connected to the interphone 2 of the basket 1 through a communication line.
The intercom, 5 is the control panel of the elevator machine room,
Reference numeral 7 denotes a weight tied to the basket 1 through the rope 6.

In FIG. 1, reference numeral 8 denotes a monitoring center 4
A central control panel installed in the inside, 9 is a low-speed operable operation button installed on the central management panel 8, 10 is a display device also installed on the central management panel 8, and 11 is a microcomputer installed on the control panel 5 A computing device including a low speed operation button 12 installed in the basket 1, a door zone detection switch 13 installed in the basket 1, and a door zone area cam 14.

Further, in FIG. 1, 15 is a landing, 16
Is a landing door, and 17 is a hoistway of the cage 1.

[0014]

Next, the operation of the first embodiment will be described with reference to FIG. FIG. 2 is a flowchart showing the operation of the first embodiment of the present invention.

In steps 20 to 21, if a passenger is trapped in the basket 1 and breaks down in a canned state during the operation of the elevator, the passenger notifies the monitoring center 4 through the interphone 2 in the basket 1.

In step 22, the central management panel 8 of the monitoring center 4 sends a command to the arithmetic unit 11 of the control panel 5 to judge a floor stop failure by the operation of the operator receiving the notification. The arithmetic unit 11 determines in advance whether the basket 1 is stopped between floors by a predetermined determination program,
The result is sent to the monitoring center 4, and the central management panel 8 displays it on the display device 10. The inter-story stop failure can be determined by dropout of the traveling relay and the level detection relay, that is, by determining that the cage 1 has stopped traveling and that the stop position is not in the door zone area.

In step 23, the operator who has judged that the floor stop failure has occurred by looking at the display device 10 presses the low-speed operable operation button 9 (by remote control), and the arithmetic operation device 11 changes the elevator operation mode from the automatic mode to the manual operation mode. Change to mode. Note that the arithmetic unit 11 may switch the operation mode to the manual mode when determining that a floor stop failure has occurred, and notify the monitoring center 4 to that effect. In this case, the operation of pressing the low-speed operable operation button 9 by the operator can be omitted.

In step 24, the operator then instructs the passenger in the basket 1 through the intercom 3 to press the low-speed operation button 12 to perform low-speed operation.

In step 25, the passengers in the basket 1
According to the instruction, for example, the down low-speed operation button 12 is pressed to start the low-speed operation.

In steps 26 to 28, when the low speed operation button 12 is pressed, the arithmetic unit 11 starts low speed operation,
When the door zone detection switch 13 attached to the basket 1 operates on the door zone area cam 14, the operation is stopped and the door of the basket 1 and the door 16 of the landing are opened. Thus, the passenger trapped in the basket 1 can escape.

In step 21, if there is no failure notification, the processing in step 22 and subsequent steps is not performed.
In step 2, if it is not a floor stop failure, the processing after step 23 is not performed.

After it is determined in step 22 that an inter-story stop failure has occurred, it is determined in advance whether the cause of the failure is a range that does not interfere with low-speed operation for safety, and the result is displayed on the display device 10 of the monitoring center 4. Is also good. Causes of failure in the above range include, for example, poor contact in operation of a switch for confirming that the door of the basket 1 is closed, malfunction of the emergency stop button in the basket 1,
Poor contact of the control relay of the control panel 5 is considered.

The first embodiment of the present invention, as described above,
Interphones 2 and 3 for transmitting a call indicating that the basket 1 is in a canned state to the monitoring center 4 and a call for a low-speed operation instruction from the monitoring center 4 to the basket 1, and the interphones 2 and 3 installed in the monitoring center 4 and being in the canned state A low-speed operation-capable operation button 9 for an operator to transmit a low-speed operation command based on a call to the effect that the low-speed operation command is received, and a low-speed operation in the basket by the passenger based on the low-speed operation instruction call. When the passenger is trapped in the basket 1, the operation mode is set to the manual mode by remote control from the monitoring center 4 because the operation device 11 includes the arithmetic unit 11 that performs low-speed operation to a predetermined position when the button 12 is pressed. It is possible to drive to a predetermined landing position as low-speed operation is possible in the basket 1, and in the case of a simple failure or the like, the passengers trapped in the basket can escape on their own. Unlikely to.
