Description

[Detailed description of the invention] The present invention relates to an elevator display device.

Conventionally, elevator display devices include those that display numbers and symbols engraved on an acrylic cover by lighting, and those that use seven segments or dot matrix to display various types of displays.

However, these devices were only used to display floors and driving directions on the ton.

In addition to simply displaying letters, numbers, and symbols, the present invention has a configuration that allows each display digit to display different display contents in different ways at the same time, and allows each display digit to display the above information according to the movement and status of the elevator. Elevator users can quickly and accurately check the movement and status of the elevator by moving the display contents vertically or horizontally, independently or in conjunction, or by moving the display contents vertically or horizontally across multiple display digits. The object is to provide a display device that allows judgment.

Examples of the present invention will be described below.

Figures 1a, b, and c are elevator car position display devices installed inside the car or at the landing.The first digit indicates the direction of the elevator, and the second
The first and third digits display the floors of the elevator, and a strip pattern is displayed for each digit at the second brightness (diagonal lines in the figure), and only this pattern is displayed in the vertical direction according to the running speed of the elevator. This is an example in which it is moved downward (downward in the figure).

21st ffla, b, c are display devices installed at the landings of the group control elevators, and with the first brightness, the first car or the car that will land at the hall in response to a hall call is displayed in the 0th digit. In the first digit, the arrow indicating the driving direction of the car is displayed moving upward, and the second brightness displays a "<"-shaped pattern moving leftward. The figure shows that the No. 2 unit on the left side operates in the 2nd direction.

In addition, the above-mentioned display device usually displays the car position and driving direction as shown in Figure 1, and indicates when the car is designated as the first car or when landing at the corresponding landing in response to a landing call. , it is also possible to switch to a fourth display.

FIG. 3 is a diagram showing the configuration of an embodiment of the present invention. In the figure, 1 is a display consisting of a 5 x 7 dot matrix, and has 5 columns each consisting of 7 display elements.The brightness control device 4 performs dynamic lighting for each column, and its cycle is determined by the output signal 5 of the oscillation circuit 4. Further, the display control devices 2A and 2B read the display data of the column corresponding to the dynamic lighting cycle from the display storage devices 3A and 3B, and output it to the brightness control bag [34]. 3A controls the display using the first brightness, and the display control device 2B and display storage device 3B control the display using the second brightness. Note that display data is set and stored in the display storage devices 3A and 3B by an elevator control bag M (not shown).

FIG. 4 is a detailed diagram of the brightness control device 34.

6 is a first counter that counts the output signal 5 of the oscillation circuit 4, and is reset to "0" the instant the count value reaches "5".

A decoder 7 reads the output 6a of the first counter 6, and the output drives each column of the display 1 in turn. In addition, the output 6a is output from the display control device 2A, 2B.
Powered. 35, 375 is an amplifier display control device 2A,
The column display data 2a, 2'b output from 2B is amplified. 67, 8 are diodes, 39.40 are resistors, and this circuit consisting of amplifiers 35, 36, diodes 37, 38, and resistors 39, 40 controls the lighting of each dot on the display 1, and The number of dots in one row of 1 (7 in this embodiment) is provided.

Since the output 2a of the display control device 2A is outputted to each dot of the display 1 via the resistor 40 and the output 2b of the display control device 2B is outputted to each dot of the display 1 via the resistors 39 and 40, the dots lit by the output 2a are The brightness of the dot (first brightness) is higher than the brightness of the dot (second brightness) lit by the output 2b. Incidentally, when both outputs 2a and 2b are output, the dot is lit with the first brightness.

FIG. 5 shows a display control device 2 that performs display using the first brightness.
It is a detailed block diagram of A. In the figure, reference numeral 8 denotes a movement period register, and the output signal 5 of the oscillation circuit 4 corresponds to the movement period when moving the display contents of the display 1 up and down or left and right.
The count setting value of 5 is written from the elevator control device. 9 is a second counter that counts down the output 5 of the oscillation circuit 4, and at the moment when it reaches "0", it starts moving at the same time as the signal 2 is preset by the output 8a of the movement period register 8. A command signal 9a is output.

Reference numeral 10 denotes a control register in which a control take consisting of display contents (1) - presence or absence of downward movement, distinction between up and down movement, presence or absence of left and right movement, and distinction between left and right movement is set and stored, and a signal 10a for each is set.

Output as i ob, i 0c, 10d. 1
1, 12. 16 is an AND circuit, 14 is an OR circuit, and 15 is an inverter. 16 is the minimum address register, 17
is a maximum address register, which sets and stores the minimum and maximum addresses of the display storage device 3A corresponding to the display contents displayed by each digit of the display 1 from the elevator control device when there is horizontal movement. 18 is the first multiplexer, and when there is no horizontal movement of the display content, the display digit setting address set in advance (the display control device in the first digit is "0", the display control device in the second digit is "0") If "5" (the third digit display control device is rlOJ) is selected and there is left/right movement, the display digit setting address is selected only when the start signal pulse is input, and then the second multiplexer 19 output 19a is selected. The second multiplexer 19 operates according to the left/right movement discrimination signal 10d.
When the display content moves to the left, the output 16a of the minimum address register 16 is selected, and when the display content moves to the right, the output 17a of the maximum address register 17 is selected and output to the first multiplexer 18.

20 is a first comparison circuit, which outputs the output 2 of the third counter 21;
It issues an output 20a to the third multiplexer 22 when 1a is greater than the output 17a of the maximum address register 17. 23 is a second comparison circuit, in which the output 21a of the sixth counter 21 is the output 16a of the minimum address register 16.
When it is smaller, the sixth multiplexer 22 receives an output 2-a. The sixth multiplexer 22 selects the output 20a of the first comparison circuit 20 when the display content moves to the left according to the left/right movement discrimination signal 10d, and selects the output 20a of the second comparison circuit 20 when the display content moves to the right. Select 23a and press O
A preset signal 22a is output to the third counter 21 via the R circuit 14.

The sixth counter 21 is preset at the output 18a of the first multiplexer 18 by the start signal sent from the electric heater control device via the OR circuit 14 or the preset signal 22a sent from the third multiplexer 22. be done. Also, AND circuit 12
The movement command signal 9a sent via the left/right movement distinction signal 10d is counted up or down.

24 is a first adder circuit, which outputs the output 6a of the first counter 6;
and the output 21a of the third counter 21 are added, and the result 24a is output to the subtraction circuit 25. The subtraction circuit 25 adds "1" to the output 17a of the maximum address register 17 and outputs 26a from the second addition circuit 26 to the output 24.
A is subtracted from a, and the result 25a is sent to the third addition circuit 2.
7, and also outputs a signal 25b' indicating whether the result of subtraction is positive, negative, or "0" to the fourth multiplexer 28.

The fourth multiplexer 28 outputs the output 26a of the second adder circuit 26 to the third adder circuit 27 when the signal 25b is negative, and outputs the output 16a of the minimum address register 16 when it is positive or "0". is output to the third adder circuit 27.

The third addition circuit 27 adds the result 25a of the subtraction circuit 25 and the output 28a of the fourth multiplexer 28, and outputs the result 27a to the interface 29. When the display storage device 3A is accessible, the interface 29 outputs the output 27a of the sixth adder circuit 27 to the display storage device 3 as an address instruction output in the display storage device 3A.
A, and at the timing when the read take 3a of the designated address from the display storage device 3A is established,
A preset signal 29a is output to the fifth counter 30 and the 8-hit shift register 31. The 8-bit shift register 31 is preset by the readout takeoff signal 29a.

A fourth counter 32 counts up the output of the AND circuit 11, and is preset to 0-1 when the count value reaches r8J or when the start signal is input.

33 is a second oscillation circuit which generates a clock signal 33a having a cycle sufficiently shorter than that of the oscillation circuit 4, and outputs it to the fifth counter 30.

[ The clock signal +j330a is output to the 8-bit shift register 31 by the number of counts until -0j.

The 8-bit soft register 31 receives this clock signal 30a.
The shift operation is performed one bit at a time in the upward or downward direction in accordance with the up/down movement discrimination signal 10b the number of times. At this time, in the case of an upward direction, the 8th bit is input to the 1st bit, and in the case of a downward direction, the 1st bit is input to the 8th bit, and so on. Further, at the time when data is preset, the eighth bit is preset to "0".

The outputs of the first to seventh bits of the 8-bit shift register 31 are sequentially connected to each of the seven display elements in each column of the display 1 through the brightness control device 34, and serve as driving signals.

Next, the operation of this embodiment will be explained with reference to FIG. FIG. 6a shows the arrangement of display elements of the display device 1, and the sixth
The figure shows the address of the display storage device 3A, and in the following explanation, the first digit display will be described.

First, a case will be described in which the display content on the display 1 does not move vertically or horizontally. At this time, the display digit setting address is set to "0", the minimum address is set to "0", and the maximum address is set to "4".

The rows of the display device 1 (FIG. 6 aO-4) are driven in order according to the cycle of the output signal 5 of the oscillation circuit 4 via the first counter 6 and the decoder 7. Since there is no movement of the display contents, the output 21a of the sixth counter 21 is the set value of the display digit setting address "0", so the output 24a of the first addition circuit 24 is the same as the output 6a of the first counter 6. They become the same and are input to the subtraction circuit 25. Here, since the maximum address is "4", the output 2 of the second adder circuit 26
6a is "5".

On the other hand, the output 24a of the first adder circuit 24 is "0" to [4].
'', the subtraction result signal 25b is always negative, so the output 28a of the fourth multiplexer 28 is the same as the output jJ26a of the second addition circuit 26. Therefore, in the third adder circuit 27, the outputs 24a to 26a
Since the output 26a is added to the result 25a obtained by subtracting , the result 27a is the first addition circuit 24
output 24a, and is input to the display storage device 3A via the interface 29.

Therefore, when the 0th column of the display device 1 is driven, the contents of the address of the 0th column in the display storage device 3A are input to the 8-bit shift register 31 as successive data 3a, and are preset by the interface 29. . The interface 29 also outputs the preset signal 29a to the fifth counter 3o, but at this time, the output 32a of the fourth counter 62 is "0", so
The output 30a of the fifth counter 0 is also "0",
8-bit shift register 61 does not perform a shift operation.

As a result, the content of the address in the 0th column 11 is displayed in the 0th column of the display 1, and similarly, the content of the address in the 1st to 4th columns is displayed in the 1st to 4th columns. They are displayed one after another, and this operation is repeated thereafter.

The above explanation is for the case where display 1 is the first digit, but the second digit is
In the case of the digit, the contents of the address in the 5th to 9th columns are displayed, and in the case of the 3rd digit, the contents of the address in the 10th to 14th columns are displayed in the same manner as above.

Next, a case will be described in which the display contents of the display device 1 are moved in the vertical direction. The driving of the column is the same as described above, and the difference is that the periodic signal of the display contents (the count value of the output signal 5 of the transmitting circuit 4) is inputted from the movement period register 8 to the second counter 9 as the output 8a. This is the point. Therefore, the second counter 9 is the output 8a of the movement period register 8.
It starts counting down from the value instructed by , and when the count value reaches "0", it outputs the movement command signal 9a once, and then repeats counting down from the count value.

When the movement command signal 9a is not output, the display 1 displays the same information as above. When the movement command signal 9a is output once, that is, when the output of the fourth counter 32 becomes "1", the preset signal 29a from the interface 29 is output.
is manually input to the fifth counter 30, the fifth counter 3° counts down once by the clock signal of the second oscillation circuit 33, so its output 30a becomes l-1
The signal becomes 1 and is output to the 8-bit shift register 61.

As a result, the 8-bit shift register 31 shifts the read data 3a once upward or downward in accordance with the vertical movement discrimination signal 10b. Therefore, the display content of the display device 1 is shifted by one line in the -f= direction or downward relative to the content of the address in the display storage device 3A.

Similarly, every time the movement command signal 9a is output, 2 lines, 3 lines
The rows are shifted sequentially, and the displayed content moves in one direction or downward.

As already explained, since the 8-bit shift register performs a rotation operation, the display contents of the display 1 also perform a rotation operation. For example, when the display content moves upward, the display content in the top row is then displayed in the bottom row. Incidentally, if necessary, the rotation operation may not be performed.

Sixth, a case will be described in which the display content on the display 1 moves in the left-right direction. First, a case will be described in which the contents of the addresses in the 0th to 14th columns of the display storage device 6A are displayed on the display 1 of the first digit 1 while sequentially moving leftward. At this time, the display digit setting address is set to "0", the minimum address is set to "0", and the maximum address is set to "14".

When the start signal is output from the electric heater control device,
This signal is inverted by the inverter 15, and in order to close the gate of the AND circuit 13, the first multiplexer 1
The output 18a of the output 18a becomes "0", and the start signal presets the sixth counter 21 via the OR circuit 14 to the value "0" of the output 18a. Also, the second
The multiplexer 19 outputs the maximum address "14" to the first multiplexer 18, and outputs the maximum address "14" to the third multiplexer 2.
2 operates to select the output 20a of the first comparison circuit 20.

When the movement command signal 9a has not been output, the display storage device 3 is displayed in the 0th to 4th columns of the display 1, as explained at the beginning.
The contents of the addresses in the 0th to 4th columns are displayed.

When the movement command signal 9a is output once, the output of the third counter 21 becomes rIJ, and the output 6 of the first counter 6 becomes
a is added by 11'' by the first addition circuit 24 to become an output 24a, which is input to the subtraction circuit 25. By the way, since the output 26a of the second adder circuit 26 is "15", the output 24a is "114". In the following case,
As in the first case described, the output 24a and the output 27a are the same. Therefore, in the 0th column of display 1,
The contents of the address in the first column are displayed. Similarly, 1st~
Since the contents of the second to fifth columns of the address are sequentially displayed in the fourth column, the displayed contents are shifted one column to the left. Similarly, each time the movement command signal 9a is output, the output 2ia of the third counter 21 increases by rlJ, and the display contents of the display 1 are shifted to the left one column at a time.

and the output 24a has a value of "11" to "15". Output 2
When 4a becomes 115, the result of the subtraction circuit 25 is 0.
Therefore, the content of the address of the sixth adder circuit 27 is displayed, and the display content moves leftward in the same manner. Further, the output 21a of the sixth counter 21 is “15
'', the first comparison circuit 20 outputs a preset signal via the third multiplexer 22 and the OR circuit 14, and the third counter 21 is preset to the output 18a of the first multiplexer 18.

In this case, there is no input pulse of the start signal, so the first
Since the output 18a of the multiplexer 18 has the minimum address set value "0", the sixth counter 21
is preset to rOJ and repeats the above operation again.

When the display content moves to the right, the setting values of the display digit setting address, minimum address, and maximum address are the same as when moving to the left, and each time the movement command signal 9a is output, the third counter 21 counts down,
When the output 21a becomes smaller than the minimum address setting value "01," the second comparator circuit 26 outputs the output 23a.
The third counter 21 has a maximum address setting value i"'14
”, and the count is down again. Therefore, contrary to the leftward movement described above, the displayed content moves rightward.

Next, if the 1st to 3rd digit display on display 1 is linked, the setting value of the display digit setting address is "0" for the 1st digit.
'', the second digit is ``5'', the third digit is ``10'', the minimum address settings are both ``0'', and the maximum address settings are ``14j'', and the operation has already been performed. Since it is the same as that described above, detailed explanation will be omitted.

Note that the present invention is not limited to the above-mentioned embodiments, and it is also possible to flicker the display content or move the display content in the vertical and horizontal directions at the same time. It can also be linked. Furthermore, the movement period of the display contents can be made variable according to the speed and state of the elevator, such as the opening/closing state of the doors, or the movement of other elevators installed in parallel.

In the above explanation, display control using the first brightness will be explained.
In addition, display control using the second brightness is performed in the same way,
The outputs 2a and 2b of the display control devices 2A and 2B are controlled by the brightness control device 64 so that they have respective brightnesses.

In addition, various types of display are possible in addition to those shown in Figures 1 and 2. For example, the pattern may not be moved but only the arrows, etc. may be moved, or only the pattern of some digits may be displayed. You can also move it or make the pattern for each digit different.

Furthermore, in the above embodiment, two types of display are performed using different brightness, but it is also possible to perform three or more types of display.Furthermore, if a two-color light emitting diode is used as the display element, display using different colors can be performed. They can also be done at the same time.

As explained above, according to the present invention, in addition to simply displaying characters and numbers, two or more types of display contents are moved independently or in conjunction with each other for each display digit depending on the movement and status of the elevator. Since the display content can be moved across a plurality of display digits, it is possible to provide an elevator display device that allows passengers to quickly and accurately judge the operating status of the elevator.
