Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an elevator display device that uses a digital display to display the car position and traveling direction in an elevator car, for example.

(Prior Art) There is an elevator display device that uses a segment mosaic display type digital display to display, for example, the car position and travel direction in an elevator car.

FIGS. 7 and 8 are front views showing a display section of an elevator display device using a digital display of such a display method.

FIG. 6 shows a digital display 1 for one-digit floor display, but there are segment display sections for two digits, 2a and 2b. The segment display parts 2a and 2b each have a 16-segment configuration in which segments S are arranged in a square shape, and further segments are arranged diagonally to form a rice character within a rectangular frame. It has become. Then, the segment display section 2a on the left side displays the descending direction "↓" using the three elements in the upper region of the Yonecedar-arranged segments.
In addition, the three elements in the - lower area are used to display the ascending direction "↑", and the segment display section 2b on the left is used to display the floor by numbers, lighting up as shown in Figure 7, for example. By selectively controlling the segment to be moved, the current floor and direction of the elevator can be notified. Moreover, FIG. 8 shows a configuration for three digits, where the segment display section 2a on the left side is used for direction display, and the segment display section 2b for the remaining two digits,
2c is used for displaying floors in numbers to inform the current floor and direction of the elevator. The former can display 9 floors, and the latter can display 99 floors.

Furthermore, in addition to numbers, it is also possible to display B (basement floor), R, P (rooftop floor), etc. in both cases.

(Problems to be Solved by the Invention) As described above, in an elevator display device in which a digital display composed of IB upper segments is provided in an elevator car and used for indicating the position and direction of the car, one segment display section is It is used for direction display, and the other segment display parts are used for numerical floor display.

In this way, if the floor display part and the driving direction display part are separate, the digital display requires at least two digits, which increases the display installation space, making it difficult to secure display installation space in a narrow car. is difficult, and
There is a problem in that the cost of the system increases because a drive circuit is required depending on the number of display digits.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an elevator display device that can improve installation space and cost.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows. In other words, a digital display with a display capacity of one digit that has multiple display elements and can display symbols indicating the elevator operating direction and characters indicating the floor of the current position by selecting the display elements, and a digital display with a display capacity of one digit that can display the elevator operating direction by selecting the display element. a data input section that receives car position data, a data control section that sequentially updates and holds the driving direction and car position data obtained by this data input section, and alternately reads out these two data; a decoder that obtains display element selection pattern data that causes the digital display to display a pattern corresponding to the data;
and a driver for selectively driving display elements of the digital display according to the pattern data.

(Operation) In such a configuration, the data input section receives driving direction and car position data from the elevator system. The driving direction and car position data obtained by the data input section are sequentially updated and held by the data control section, and the data control section alternately reads these two data and provides them to the decoder. Then, the decoder outputs pattern data of a display element that causes the digital display to display a pattern corresponding to the read data and provides it to the driver. The driver selects and drives the display elements of the digital display according to this pattern data. As a result, a digital display with a display capacity of one digit has multiple display elements such as the number of floors where the car is currently located and an arrow symbol for the direction of operation, and the selection of this display element indicates the direction of elevator operation. A digital display with a display capacity of one digit that can display symbols and characters indicating the floor of the current location is configured to alternately display the numerical value of the floor where the vehicle is currently located and the symbol of the driving direction. As a result, it is possible to display the position and direction using a single-digit digital display, and it is possible to provide an elevator display device that can significantly improve installation space and cost.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 6.

FIG. 1 is a block diagram showing the overall configuration of this device, and FIG. 2 is a diagram showing the segment configuration of a digital display used in this device.

The digital display 11 shown in FIG. 2 is a digital display with a single digit display. That is, the segment display section 2 is for one digit. The segment display section 2 has segments S arranged in the shape of a square as described in the prior art, and further segments arranged diagonally so that the shape resembles a square inside a rectangular frame. This is the display section for the upper IB segment. Then, among the segments arranged in Yonesugi, three elements in the upper area are used to display the descending direction "↓", and three elements in the lower area are used to display the ascending direction "↑゛". The entire section 2 is used to display the floor numerically, and by selectively controlling the segments to be lit as shown in FIGS. 3(a) to (e), the current floor and direction of the elevator can be determined. It is designed so that notifications can be given alternately.

A control block diagram for performing such control is as shown in Fig. 1, in which 12 is a driving direction detection unit that detects the driving direction of the elevator and outputs driving direction data, and 13 is a driving direction detection unit that detects the car position. This is a car position detection unit that outputs car position information, and these are functional elements of the elevator system. 14 is a driving direction data section that receives driving direction data from the driving direction detecting section 12; 15 is a car position detecting section 13;
A car position data section 16 receives the car position information from the driving direction data section 13 and the car position data section 15.
17 is a data alternate readout unit that alternately reads out the above two data stored in this buffer 16; 18 is a data alternate readout unit that reads out the data read out by this data alternate readout unit 17 into a number pattern or a symbol pattern; This is a decoder that outputs a signal for selecting segments corresponding to the segments necessary for display in order to display them on the digital display 11. These configurations are realized by the microcomputer 20, for example. 19
is a driver that drives the segment indicated by the signal output from the decoder 18. 15-1
9 constitutes a control panel 21.

In this device having such a configuration, the driving direction detection unit 12 detects the driving direction of the elevator at a predetermined period, and outputs driving direction data, which is provided to the buffer 1B via the driving direction data unit 14. Further, the car position is detected by the car position detecting section 3 at a predetermined period, and the car position information is stored in the buffer 1B via the car position data section 15. Therefore, the latest driving direction data and car position data are updated and stored in the buffer 1B.

The latest information on the driving direction data and car position data stored in the buffer 1B in this way is given to the data alternate reading decoder 18, and the decoder 18
7 outputs a segment selection signal corresponding to a necessary segment for displaying the data read out on the digital display 11 in a numerical pattern or symbol pattern. The signal output from this decoder 18 is given to a driver 19, and the driver 19 drives the segment indicated by the signal in accordance with this signal.

As a result, for example, if the elevator car is moving upward from the first floor to the second floor, the digital display 11 will first display "1" and then "↑".
, and then "2" will be displayed. Therefore, passengers in the car can tell the driving direction and current position of the car by setting the microcomputer software to display numbers in the order of the lower digits from the single-digit digital display, and feeding the data to the decoder 18 in that order. Floor locations can be displayed.

In this way, the driving direction and position of the car can be displayed with a single display digit, and the display can be made compact, allowing the installation space to be kept to a minimum. In addition, since the number of digits is single, the number of drive circuits can be reduced, and costs can be reduced.

The segment arrangement of the digital display 11 may be a combination of a square arrangement and a diamond arrangement, as shown in FIG.
Alternatively, it is also possible to use a 13-segment arrangement as shown in FIG.
Even in the latter case, use the center segment to ``↑'' as shown in Figure 5.

Since "↓" can be displayed, the structure can be simplified and energy can be saved by reducing the number of segments.

Further, in this device, the display element may be replaced with a mosaic display using segments as described above, and a light source arranged in a dot matrix arrangement may be used. In addition, although the driving direction and car position are displayed alternately, if the car is waiting on a specific floor such as the standard floor, only the position display may be continuously displayed. In addition to being used as a device, it can also be used as a guide display for halls.

〔Effect of the invention〕

As described in detail above, according to the present invention, it is possible to provide an elevator display device that can improve installation space and cost.
