The present invention relates to an elevator position display lamp control circuit that enables the passenger to wait for the current position of the elevator by lighting the position display lamps installed on the platform of each floor, in particular, only the platform of the floor with the call registration location An elevator position display lamp control circuit that enables to turn on the display lamp.

In the conventional elevator position display lamp control circuit, as shown in FIG. 1, the fixed segments SEG ₁ , SEG ₂ ,... , (SEG _n ), each floor position indication lamp (L ₁₁ -L _n1 ), (L ₁₂ -L _n2 ) _,. And (L _1n -L _nn ) are commonly connected to each other to display the current position of the elevator.

For example, when the elevator is located on the first floor and its movable finger (FIN) is in contact with the first-floor fixed segment SEG ₁ , all the first-floor position indication lamps L _11- L _n1 installed on each floor are all present. It lights up to indicate that the elevator is located on the first floor.

By the way, since the elevator position display device is a device for indicating the position of the elevator to the passengers who want to use the elevator, only the position display lamp of the floor with the platform call registration is lit, but in the conventional apparatus as described above, Irrespective of the fact, the location display lamps of all floors are turned on to display the current location of the elevator, so that the power consumption increases without the need for the location display lamps.

In view of the above, the present invention, while the movable finger of the elevator is in contact with the fixed segment of each floor to light up the location indicator lamps installed on each floor to display the current position of the elevator, the call registration is determined by determining the presence or absence of the call registration Invented to turn on only the position display lamp of the floor, which will be described in detail by the accompanying drawings as follows.

2 is an elevator position display lamp control circuit diagram of the present invention, as shown in the figure, each floor fixed segment (SEG ₁ ), (SEG ₂ ), ... in contact with the movable finger (FIN) of the elevator. , (SEG _n ), each floor position indication lamp (L ₁₁ -L _n1 ), (L ₁₂ -L _n2 ) _,. (L _1n -L _nn ), wherein each floor position indication lamp (L ₁₁ -L _1n ), (L ₂₁ -L _2n ),... , (L _n1 -L _nn ) to diodes (D ₁₁ -D _1n ), (D ₂₁ -D _2n ) _,. , Switching elements SW ₁ , SW ₂ ,..., Through (D _n1 -D _nn ), respectively. , Common connection to the light-receiving side of (SW _n ), and then the respective light emitting layers are called. , and common connection to the power supply terminal (V ₂ ) through (nD) and common connection to the operating lamp detection relay contact point (A ₁ ) to the display lamp (LS ₁ -LS _n ) during operation of each floor. The lamps (L ₁₁ -L _1n ), (L ₂₁ -L _2n ), and (L _n1 -L _nn ) are 1-n floor positioning lamps installed on the 1st, 2nd, and nth floors respectively, and the diodes (D _11- D _1n , D ₂₁ -D _2n , D _n1 -D _nn ) are backflow prevention diodes, and the switching elements (SW ₁ -SW _n ) are composed of photocouplers but can be replaced by other types of switching elements. Of the relay contacts (1U, 2U, 2D, nD), 1U and 2U are the rising call registration relay contacts respectively connected when the rising call is registered on the first and second floors, and 2D and nD are the second and top n. The falling call registration relay contact is connected when the falling call is registered on the floor, and the operation state detection relay contact (A ₁ ) is the contact that is connected only while the elevator is operating. On-floor display lamps LS ₁ -LS _n are in-flight display lamps respectively installed on the 1-n floors.

If described in detail the effects of the present invention configured as described above.

Assuming that the elevator is located on the first floor while the power supplies V ₁ and V ₂ are applied, the movable finger FIN of the elevator contacts the first floor fixed segment SEG ₁ .

At this time, if the 2nd floor call up registration relay contact (2U) or the 2nd floor call down registration relay contact (2D) is connected by registering the rising or falling call on the second floor, the power supply (V ₂ ) is the contact (2U) or contact Since power is applied to the light emitting portion of the switching element SW ₂ through 2D to turn on the light receiving portion thereof, the power supply V ₁ is movable finger FIN and the first layer fixed segment SEG ₁ , and the first layer installed on the second layer. As it flows through the position display lamp L ₂₁ and the diode D ₂₁ to the light receiving unit of the switching device SW ₂ , only the first floor position display lamp L ₂₁ installed on the second floor is turned on.

However, at this time, if there is no falling call registration on the nth floor and the nth falling call registration relay contact nD is opened, the switching element SW _n remains off, so that the first floor position display lamp L _n1 installed on the nth floor. ) Does not light up.

Similarly, the elevator is located on the second floor and its movable finger (FIN) is in contact with the second-floor fixed segment (SEG ₂ ). The first-floor upcall registration relay contact (1U) and the n-th floor downcall registration relay contact (nD) If it is connected, only the second floor position display lamps L ₁₂ (L _n2 ) provided on the first floor and the n floor are turned on.

In this way, the floor position indication lamp, in which the elevator is located, is lit only on the floor on which the call is registered.

Further, (representing the first layer in a specific layer), a layer, such as from the reference layer specific layer as the power source as shown by the broken line to the light-receiving side of the switching element (SW ₁₎ of a specific layer in FIG. 2 (V ₂ ), The location indicator lamp corresponding to the floor in which the elevator is located among the location indicator lamps (L _11- L _1n ) installed on the first floor, which is located on the first floor, regardless of whether or not the first floor is called up or not. do. That is, when, if located on the second floor, the elevator 2 is installed on the first floor, regardless of the rise called registered oil, free of the first floor layer position indicator lamp (L ₁₂₎ lights up and, as the elevator is located in the n layer formed in the first layer n The floor position indication lamp _L1n is turned on.

In addition, since the driving state detection relay contact A ₁ is connected while the elevator is in operation, all of the driving lamps LS ₁ -LS _n installed on each floor are turned on to indicate that the elevator is in operation.

As described above, the present invention only turns on the position display lamp of the floor where the landing call is registered, so that unnecessary power consumption can be eliminated, thereby reducing the operation cost of the elevator, and greatly reducing the lighting time of the position display lamp, thus displaying the position. This has the advantage of being able to extend the life of the lamp, which improves the reliability of the product.
