Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an improvement of a device for monitoring elevators.

[Prior Art] A conventional elevator monitoring device will be explained with reference to FIGS. 1 and 2.

Figure 1 shows a monitoring panel installed in a manager's room, etc. In the figure, WB is the monitoring panel, AK is the key switch for earthquake control operation, AL is the indicator light, and BK is the one for fire control operation. The key switch, BL is the indicator light, CK is the key switch for private power generation control operation during power outage, CL is the indicator light, UL is the direction light during upward operation, DL is the direction light during downward operation, PL is the direction light for car position. It is an indicator light. Here, an example is shown in which four elevators are installed in parallel.

Figure 2 shows the lighting circuit for the control operation indicator light. In the figure, (+) and (-) are power supply buses for control, and Aa is energized when an earthquake control operation command is input, ending control operation. Then, Ba is the normally open contact of the earthquake control operation relay (not shown), which de-energizes, and Ba is the normally open contact of the fire control operation relay (not shown), which performs the same operation.
Similarly, Ca is a private power generation control operation relay (not shown)
It is a normally open contact.

In the above configuration, for example, the key switch AK
When is operated and an earthquake control operation command is input, the earthquake control operation relay is energized and contact Aa is closed.
The earthquake control operation indicator light AL is lit. Also,
If you operate key switch BK in this state, the contacts will
By closing Ba, the fire control operation indicator light BL is also lit.

[Problems to be Solved by the Invention] In the conventional configuration, the lighting circuits for the indicator lights are independent of each other for each control operation, so for example, if a fire or earthquake occurs during a power outage, multiple control operation commands may be input. In this case, even though the elevator performs controlled operation according to a predetermined priority order, the indicator lights will light up for all control operation commands input, so the manager etc. will not know which control operation is being performed. It was unclear whether the system was being implemented, causing unnecessary confusion.

[Means for Solving the Problems] In order to solve the above problems, the present invention relates the indicator lights for each control operation, and when multiple control operation commands are input, a predetermined Among the control operations carried out according to the priority order, only the indicator light of the control operation with the highest priority at that time is turned on and the others are turned off, or all the indicator lights of the control operation to which the operation command has been input are turned on. Regardless of the number of input control operation commands, such as flickering only the highest priority indicator light at that time, the control operation that has the highest priority at that time, that is, the control operation that is actually being carried out, can be set aside from other control operations. It is characterized by comprising means for displaying in a manner different from that of the above.

[Example] Fig. 3 is a diagram showing an example of the indicator light lighting circuit according to the present invention. The closing contacts and others are the same as in FIG. 2.
Here, a case is shown in which the order of priority for control operation is earthquake control operation, fire control operation, and private generation control operation.

In the above configuration, the key switch AK~
When CK is operated and all control operation commands are input, all contacts Aa to Ca are closed, and the most prioritized earthquake control operation is started by a circuit not shown. At this time, indicator light AL lights up to indicate that earthquake control operation is in progress, but since contact AB is open, other indicator lights BL and
CL is off. When the earthquake control operation is eventually completed, the contact Aa is opened and the indicator light AL is turned off, while the contact Ab is closed and the indicator light BL for the fire control operation, which has the next priority, is turned on. When the fire control operation is completed, a private fire control operation is carried out in the same way, and only the indicator light CL lights up. In this way, even if a plurality of control operation commands are input, only the indicator light for the control operation currently being performed is always lit.

FIG. 4 is a diagram showing another embodiment of the indicator lamp lighting circuit according to the present invention. In the figure, Aa ₁ to _{Aa 4} are normally open contacts of the earthquake control operation relay described above, and Ba ₁ to _{Ba 3}
Similarly, Ca ₁ and Ca ₂ are normally open contacts of the fire control operation relay, F is a flicker relay, and F ₁ to _{F 3} are their contacts.

In the above configuration, the key switch AK~
Assuming that CK is operated and all control operation commands are input, contacts Aa to Aa ₄ , Ba ₁ to _{Ba 3} , Ca ₁
~Ca ₂ is closed, the flickering relay F is energized,
Earthquake control operation begins. At this time, the indicator light AL
~CL are all lit, but only the indicator light AL flickers due to contact _F1 , indicating that earthquake control operation is in progress. Eventually, when the earthquake control operation ends, the indicator light AL goes out due to the opening of contact Aa ₂ , and the indicator light BL flickers through contact F ₂ due to the opening of contact Aa ₃ , indicating that fire control operation is being performed. Show that. Similarly, after the fire control operation is completed, the private fire control operation is performed and only the indicator light CL flickers. In this way, the control operation command is input and all the indicator lights turn on, and
Of these, only the indicator light for the currently underway controlled operation flickers.

[Effects of the invention] According to the invention, even if an abnormal situation occurs and multiple control operation commands are input, the manager etc. will be able to clearly know which control operation is actually being carried out. This can prevent unnecessary confusion and operational errors.

It should be noted that some vehicles are equipped with a separate indicator light indicating the completion of the controlled operation along with an indicator light indicating the completion of the controlled operation, and the present invention can be similarly applied to the indicator light indicating the completion of the controlled operation.
