Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a controlled operation indicator for an elevator, and particularly in an elevator with controlled operation, an elevator controlled operation indicator suitable for displaying the completion of controlled operation at a place where the controlled operation has been instructed. Regarding.

Conventional emergency elevator control operation indicators either display at all times, regardless of whether the elevator is in normal operation or firefighting operation, as long as the elevator door is open at the return floor, or when the elevator is on the return floor during firefighting operation. It was showing when I arrived.

Therefore, in the conventional display system, the display is displayed at all times or every time the elevator arrives at the call floor during firefighting operations.

However, the emergency elevator control operation indicator is originally intended to notify the administrator that the elevator has arrived at the called floor when the elevator is called back to the called floor by remote control by the manager from a monitoring room, etc. This is the purpose.

Therefore, there is no need to display the display not only during normal operation but also during firefighting operations.

In addition, in the case of emergency elevators, operations equivalent to controlled operations include forced operation to the called floor due to a forced recall command, and stopped operation to the nearest floor due to an earthquake control command, but consideration must be given to these. Not done.

In addition, a control operation indicator for private power generation control elevators that has recently been considered displays an indicator when the elevator arrives at the called floor with a forced call command, and when the elevator leaves the called floor with a command to continue operation. It has been found that there is a phenomenon in which the display does not display when the vehicle is called, and then displays the display again when the vehicle arrives at the call-back floor.

Therefore, during operation using the private power source, the display will be displayed each time the elevator arrives at the return floor.

However, the control operation display of the private power generation control elevator is
The purpose of this is to display that the elevator has arrived at the called-up floor due to a forced call-back command, thereby informing the manager that it is okay to issue a command for continued operation.

Therefore, there is no need to display the display after the administrator instructs continued operation.

In addition, if another control operation is ordered while the private power source is in continuous operation, if the call-back floor for private power generation control and the call-back floor for other control operations are different, other control operation It was difficult to determine whether the recall was completed or not.

The purpose of the present invention is to improve the shortcomings of the prior art described above and the display device currently under development by the inventor of the present invention, and to accurately display the completion of control operation to the manager, thereby preventing erroneous operation of firefighting operation or continuous operation. To provide an elevator control operation indicator that enables reliable commands without worry.

A feature of the present invention is that an elevator monitoring station is provided with a display that indicates the completion of control operation, and this display lights up when the elevator arrives at a specific floor in response to a command to turn the pipes. The system is designed to prevent the indicator from lighting up when this occurs.

The present invention will be explained in detail below using the embodiments shown in FIGS. 1 to 3.

FIG. 1 is a circuit diagram showing an embodiment of the drive circuit for the control operation indicator for an elevator according to the present invention, and shows the case of an emergency elevator, in which an indicator light is used as the indicator.

In Figure 1, 1 is an indicator light, 2 is a relay contact that closes in response to a forced call command, 3 is a relay contact that opens in response to a firefighting operation command, and 4 is a call-back floor arrival check relay that closes when the elevator arrives at the call-back floor. Contact, 5
6 is an operation check relay contact that is closed by an earthquake control command, 6 is a relay contact that is open while the elevator is operating,
EA and EB are driving power supplies.

Next, in the emergency elevator with earthquake control operation, a forced call command is issued to the elevator in normal operation.
A series of operations will be described when the elevator arrives at the return floor, then firefighting operation is ordered, and earthquake control is ordered during the firefighting operation.

During normal operation, the forced recall command relay contact 2 and the earthquake control command relay contact 5 shown in FIG. 1 are open, so the circuit for the indicator light 1 is not formed, so the indicator light 1 does not light up.

Next, when a forced recall command is issued, contact 2 is closed, and when the elevator arrives at the recall floor, contact 4 is closed.

Therefore, a circuit EA-2-3-4-1-EB is formed, and the indicator lamp 1 lights up.

Next, when a firefighting operation command is issued, the contact 3 is opened and the indicator light 1 is turned off.

Next, when earthquake control operation is commanded to the elevator during firefighting operation, contact 5 closes, and when the elevator stops at the nearest floor, contact 6 closes, and EA-5-6-1-
The EB circuit is formed and the indicator lamp 1 lights up.

As described above, according to the embodiment shown in FIG. 1 does not light up, so it is possible to provide a rational control operation indicator that does not display the display unless it is necessary.

Moreover, since it is only a combination of relay contacts, the configuration is simple.

FIG. 2 is a circuit diagram showing an embodiment of the operating circuit for another embodiment of the elevator controlled operation indicator of the present invention, and FIG. 3 shows another embodiment of the drive circuit for the controlled operation indicator of the present invention. The circuit diagram shows the case of a private power generation control elevator, and an indicator light is used as an indicator.

In Figure 2, 7 is a control operation check relay, 8 is a call-back completion check relay, 9 is a private power generation forced call-back command relay contact, 10 is a fire control command relay contact, 1
1.12 is an earthquake control command relay contact, 13 is a private power generation continuation command relay contact, 14 is a recall floor arrival check relay contact, and P and N are relay operation power supplies.

In addition, in Fig. 3, 15 is a control operation indicator light, γ-1
8-1 is a contact point of the control driver nick relay 7, and 8-1 is a contact point of the recall completion check relay 8.

Next, in addition to private power generation control operation, in an elevator with fire control operation, the private power generation control commands continuous operation after arriving at the call floor, and the sequence of events when fire control operation is ordered while the private power generation control continues operation. The operation will be explained.

For elevators that are stopped at a floor other than the return floor,
When a forced recall command is issued by a private power source,
The elevator leaves for the called floor.

In this case, the controlled operation check relay 7 is energized by the circuits P-9-13 to P-7-N in FIG.

At this time, the recall completion check relay 8 is also energized by the circuit P-12-14-8-N.

Therefore, as is clear from Fig. 3, EA-(7-1)-
Since the circuit (8-1)-15-EB is not configured, the indicator light 15 remains off.

Next, when the elevator arrives at the call-back floor, the circuit of the call-back completion check relay 8 shown in FIG. 2 opens by opening the call-back floor arrival check relay contact 14.
Relay 8 is deenergized.

Therefore, in Figure 3, EA-(7-1)-(8-1)
-15-EB circuit is formed and indicator light 15 lights up,
Displays that the elevator has arrived at the called floor.

Next, when the manager commands this elevator to continue operation, the continuous operation command relay contact 13 shown in FIG. 2 opens, the control operation check relay 7 is deenergized, and the circuit of the indicator light 15 shown in FIG. , the circuit is opened by opening the relay contact 1-1, and the indicator light 15 goes out.

Next, when fire control operation is commanded to the elevator that is in continuous operation, the circuit P-10-7-N in Figure 2 is formed.
Control operation check relay 7 is energized again.

The elevator then arrives at the called floor according to the fire control operation command.

When the elevator arrives at the called floor, the circuit of the call completion check relay 8 is opened by the opening of the call back floor arrival check relay contact 14, and the relay 8 is deenergized.

And EA in Figure 3 - (7-1) - (8-1) -1
The circuit 5-EB is formed and the indicator light 15 lights up, indicating that the elevator has completed controlled operation by fire control.

Although the explanation is omitted, when earthquake control operation is ordered,
An indicator light 15 is turned on when the elevator stops at the nearest floor.

As described above, according to the embodiments shown in FIGS. 2 and 3, when the private power generation control elevator arrives at the recall floor due to a forced recall command or fire control command, and when the elevator arrives at the nearest floor due to an earthquake control command, Except when stopped at
Since the indicator light 15 does not light up, it is possible to provide a rational controlled operation indicator that does not display the display unless necessary.

Moreover, the configuration is simple because it is only a combination of a relay and a relay contact.

As explained above, according to the present invention, the configuration is simple;
This has the remarkable effect of providing a rational control operation indicator that does not display information unless it is necessary.
