And described in detail the working effect as follows.

7 is periodically started every 40 ms, and reads the elevator status data from the elevator control unit 30 to store the current position, direction, speed, operation mode, and the like, and is currently displayed on the card display unit CD. If the display data is read and then there is no change compared to the elevator state table stored in the RAM 24 of the interface unit 20, the display data processing sub which processes the current display data read above. Run the routine. That is, as shown in FIG. 8, first, a basic display format such as direction display, floor molecule display, operation mode display, etc. is prepared and stored in the RAM 24, and if there is a change in direction by checking whether the direction has changed. Then, the direction data is read from the table of the ROM 23 as shown in FIG. 6 to change the direction display data of the basic display data. Then, if there is no change in the direction, check whether the operation mode is changed. At this time, if the operation mode is changed, the operation mode display data of the created basic display data is changed, and if there is no change in the operation mode, the position of the elevator is changed. If the position of the elevator is changed, at this time, the graphic data is generated by adding the symbol data of the current position layer to the floor display data of the existing display data already prepared as above, and storing the result in the RAM 24. .

After that, if the destination floor is registered, the nearest stop floor is searched for, updated with graphic data added with the current location layer symbol data read from the ROM 23, and the data is stored on the RAM 24. Let's do it.

The graphic data thus created is transmitted to the card display unit CD through the input / output buffer 25 of the interface unit 20 to perform a graphic display as shown in FIG. On the other hand, when the elevator arrives at the stop floor and starts deceleration, it performs the flicker operation as shown in (c, d, e) of FIG. 3, and if the elevator is not completely stopped or the elevator is decelerating above, the fixed graphic The data is displayed, control is transferred to the main program by the reset command, and control is performed again and again from the start step again after 40 ms.

As described above, the present invention is controlled by dividing the in-car display part of the elevator into three areas of the character part, the background part, and the outer edge part of the elevator, and processing the next stop layer on the display function of the card display part by displaying the edge of the border. When the elevator stops at the start of deceleration to stop on the target floor, the passengers in the car are expected to arrive at the passengers by flickering the text, background, and outer borders. In addition to knowing the current position of the car, it is possible to know in advance which floor to stop.In addition, the arrival forecast of the car can allow passengers to prepare to get off in advance a few seconds before the arrival of the target floor. Increased transportation efficiency can be expected, and passengers can wait in the car comfortably to the target floor. There is an effect that makes possible to improve the persimmon.
