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 display various types of displays using seven segments or dot matrix.

However, these devices only serve to indicate floors and driving directions.

An object of the present invention is to provide a display device that not only displays letters, numbers, and symbols, but also allows elevator users to quickly and accurately judge the movement and status of an elevator.
To this end, the present invention has a configuration in which each display digit can simultaneously display different display contents in different ways, and is further divided into those in which the display contents are kept stationary and those in which the display contents are both moved and stopped. It is something that In the case of floor markings, etc. where it is necessary to read the displayed contents accurately, the displayed contents are held still to make it easier to read, and it is better to understand the indicated direction than to read the displayed contents accurately. In the case of a direction display such as an important driving direction, each display digit that displays the direction may be used independently or in conjunction with each other to move or stop the display content in the direction indicated by the direction display, thereby improving the display effect of the display device. When displaying a pattern, each display digit displaying a pattern is made to move or stop in any direction by independently or in conjunction with each other.

Examples of the present invention will be described below.

In this embodiment, a band-shaped pattern is displayed for each digit, and only this pattern is moved in the vertical direction (downward in the figure) in accordance with the traveling speed of the elevator.

Figures 2a, b, and c are display devices installed at the landings of group control elevators, and depending on the first brightness, the third digit indicates the car that is ahead of the car or the car that will land at the hall in response to a hall call. , the first digit displays an arrow indicating the driving direction of the car so that it moves upward, and the second brightness displays a dogleg pattern that moves leftward. and
The figure shows that the No. 2 machine on the left is operating in the upward direction.

Further, the display device normally displays the car position and driving direction as shown in Fig. 1, and when the car is designated as the first car or when the car arrives at the hall in response to a hall call, It is also possible to switch to the display shown in FIG.

In the figure, 1 is a display consisting of a 5×7 dot matrix, which has 5 columns each consisting of 7 display elements, and is dynamically lit one by one by a display mode control device 34. The cycle is determined by the output signal 5 of the oscillation circuit 4.
Further, the display control devices 2A, 2B read display data of a column corresponding to the dynamic lighting cycle from the display storage devices 3A, 3B, and output it to the display mode control device 34. In this embodiment, display data with a high priority is stored in the display storage device 3A, and display data with a low priority is stored in the display storage device 3B.

and 40 to each dot on the display 1, so the brightness (first brightness) of the dot lit by output 2a, that is, the output of display data with a high priority, is higher than that of output 2b. In other words, the brightness is greater than the brightness (second brightness) of the dots lit by the output of display data with a lower priority. Note that if both outputs 2a and 2b are output, the first
Since the dots are lit depending on the brightness of the display data, the output 2a of the display data having a high priority is always displayed preferentially.

output to the adder circuit 27.

The third addition circuit 27 receives the result 2 of the subtraction circuit 25.
5a and the output 28a of the fourth multiplexer 28, and the result 27a is added to the interface 2.
Output to 9. When the display storage device 3A is accessible, the interface 29 outputs the output 27a of the third addition circuit 27 to the display storage device 3A as an address instruction output in the display storage device 3A,
At the timing when the read data 3a of the specified address from the display storage device 3A is established,
Fifth counter 30 and 8-bit shift register 3
The preset signal 29a is outputted to 1. The 8-bit shift register 31 receives this preset signal 29a.
Accordingly, the read data 3a is preset.

A fourth counter 32 counts up the output of the AND circuit 11, and is preset to "0" when the count value reaches "8" 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 fifth counter 30 is preset at the output 32a of the fourth counter 32 by the preset signal 29a from the interface 29, and set to "0" by the clock signal 33a of the second oscillation circuit 33.
The clock signal 30a is counted down until it reaches "0" and outputs the clock signal 30a to the 8-bit shift register 31.

The 8-bit shift register 31 outputs the vertical movement discrimination signal 10 as many times as the clock signal 30a.
Shift operation is performed one bit at a time upward or downward according to b. At this time, in the upward direction, the 8th bit is input to the 1st bit, and in the downward direction, the 1st bit is input to the 8th bit, and so on. Also, at the time the 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 via the display mode control device 34 and become 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 FIG. 6b shows the address of the display storage device 3A. 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 1 (a0 to a4 in FIG. 6) are driven sequentially via the first counter 6 and decoder 7 in accordance with the cycle of the output signal 5 of the oscillation circuit 4. Since there is no movement of the display contents, the output 21a of the third 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 26a of the second adder circuit 26 is "5". On the other hand, since the output 24a of the first adder circuit 24 is one of "0" to "4", the signal 25b of the subtraction result is always negative, so the output 28a of the fourth multiplexer 28 is one of "0" to "4". This is the same as the output 26a of the adder circuit 26.
Therefore, in the third adder circuit 27, the output 24a
The result of subtracting 26a from 25a is the output 26a.
As a result, the result 27a is
It matches the output 24a of the first adder circuit 24 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 content of the address of the 0th column in the display storage device 3A is input to the 8-bit shift register 31 as read data 3a, and
Preset by 9. The interface 29 also outputs a preset signal 29a to the fifth counter 30, but at this time, since the output 32a of the fourth counter 32 is "0", the output 30a of the fifth counter 30 is also "0". '', and the 8-bit shift register 31 does not perform a shift operation.

As a result, the content of the address in the 0th column is displayed in the 0th column of the display 1, and the contents of the address in the 0th column are displayed in the same way.
The contents of the addresses in the first to fourth columns are sequentially displayed in columns 1 to 4, and this operation is repeated thereafter.

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

Next, a case will be described in which the display content on the display 1 moves in the vertical direction. The driving of the column is the same as described above, except 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. The point is that there is. Therefore, the second counter 9 starts counting down from the value instructed by the output 8a of the movement period register 8, and when the count value reaches "0", the movement command signal 9a is set to 1.
The count value is output twice, and the count down from the count value is repeated thereafter.

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, the fourth counter 32
When the output of becomes "1", the interface 29
The preset signal 29a from the fifth counter 3
0, the fifth counter 30
Since the count is down-counted once by the clock signal of the oscillation circuit 33, the output 30a becomes "1" and is output to the 8-bit shift register 31. 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 on the display 1 is stored in the display storage device 3A.
The content of the address within is shifted one line upward or downward and displayed. Similarly, each time the movement command signal 9a is output, the display is sequentially shifted to two lines, then three lines, and the displayed content moves upward or downward. Furthermore, as already explained, since the 8-bit shift register performs a rotating operation, the display contents of the display 1 also perform a rotating operation. For example, when the display content moves upward, the display content in the top row is then displayed in the bottom row. Note that the rotation operation may not be performed if necessary.

Thirdly, 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 3A are displayed on the first digit display 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 a start signal is output from the elevator control device, this signal is inverted by the inverter 15 and the gate of the AND circuit 13 is closed, so that the output 18a of the first multiplexer 18 becomes "0" and the start signal is The signal is OR circuit 14
The third counter 21 is preset to the value "0" of the output 18a. Further, the second multiplexer 19 outputs the maximum address "14" to the first multiplexer 18, and the third multiplexer 22 operates to select the output 20a of the first comparison circuit 20.

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

When the movement command signal 9a is output once, the output of the third counter 21 becomes "1", and the output 6a of the first counter 6 is incremented by "1" by the first adding circuit 24. The output becomes the output 24a and is input to the subtraction circuit 25. By the way, the second addition circuit 2
Since the output 26a of 6 is "15", the output 26a of the output 2 is "15".
When 4a is "14" or less, the output 24a and the output 27a are the same, as in the case described first. Therefore, in the 0th column of the display 1, the 1st
The contents of the address in the column are displayed. Similarly, the first
Since the contents of the second to fifth columns of the address are sequentially displayed in the to fourth columns, the displayed contents are shifted one column to the left. Similarly, the movement command signal 9a
The output 21a of the third counter 21 is incremented by "1" every time " is outputted once," and the display contents of the display 1 are shifted to the left one column at a time.

When the output 21a of the third counter 21 becomes "11", the output 24a becomes a value between "11" and "15". When the output 24a becomes "15", the result of the subtraction circuit 25 becomes "0", so the output 27a of the third addition circuit 27 becomes "0", and the 0th to 4th columns of the display 1 , the contents of the 11th to 14th and 0th column addresses of the display storage device 3 are displayed, and the displayed contents move leftward in the same manner. Also, the third counter 21
When the output 21a of becomes "15", the first comparator circuit 2
0, the preset signal is output via the third multiplexer 22 and the OR circuit 14, and the third counter 21 outputs the preset signal from the output 1 of the first multiplexer 18.
8a. In this case, since there is no input pulse of the start signal, the output 18a of the first multiplexer 18 has the minimum address set value "0", so the third counter 21 is preset to "0" and is returned to the above-mentioned state. Repeat the action.

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 the third counter 21 is set every time the movement command signal 9a is output. counts down, and when its output 21a becomes smaller than the minimum address setting value "0", the second
The comparator circuit 23 outputs an output 23a, and the third counter 21 is preset to the maximum address setting value "14" and starts counting down again. Therefore, contrary to the leftward movement described above, the displayed content moves to the right.

Next, if the displays on the display 1 for the first to third digits are linked, the setting value of the display digit setting address is "0" for the first digit, "5" for the second digit, The third digit is "10", the minimum address setting values are both "0", and the maximum address setting values are both "14", and the operation is the same as that already explained, so please refer to the details below. Further 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 displayed content can be made variable according to the speed and state of the elevator, such as the opening/closing state of the door, or the movement of other elevators installed in parallel.

In the above explanation, display control using the first brightness has been explained, but display control using the second brightness is also performed in the same way, and the outputs 2a and 2b of the display control devices 2A and 2B are controlled by the display mode control device 34. are controlled to have respective brightnesses.

In addition, various types of display are possible in addition to those shown in Figures 1 and 2. For example, only the arrows, etc. can be moved without moving the pattern, or only the pattern of some digits can 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 a display element, display in different colors can be performed. You can also do both at the same time.

As explained above, according to the present invention, not only characters and numbers are displayed, but also two or more types of display contents are simultaneously displayed for each display digit depending on the movement and condition of the elevator, and The contents are divided into those that remain stationary and those that move and stop. When moving the displayed contents, each display digit can be moved independently or in conjunction with each other, or the display can be displayed across multiple display digits. Since the contents are moved, it is possible to provide an elevator display device that allows passengers to quickly and accurately judge the operating status of the elevator.
