Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an elevator control device.

[Prior Art] In recent years, display devices for providing various information to passengers have been increasing in elevator cars, landings, and the like. For example, in JP-A-62-105877, general information such as time information is displayed on displays installed in the car and at the landing, along with greeting information appropriate to the time, and this is combined with the above general information. A combined display device has been proposed. In addition, along with the diversification of display information, the functionality of display devices has progressed, and devices that simply display only text have expanded to include those that display images, etc., providing more information to passengers. A wide variety of information is being provided.

[Problems to be Solved by the Invention] In such conventional elevator display devices, as building equipment and functions have improved, the functions of the display devices themselves have become more sophisticated, and the configuration of the devices has become more complex. The causes of failures in devices are also increasing, and therefore maintenance work to prevent failures has become extremely important. Furthermore, as buildings become larger and more equipped, the number of floors equipped with display devices also increases, making detailed inspection work for these display devices even more time-consuming. In particular, when inspecting landing display devices, workers must accurately memorize the equipment floor of each display device, and there is a possibility that failure modes that cannot be detected by testing with normal display contents may occur. There was also a problem that efficient inspection work was difficult.

This invention was made in order to solve the above-mentioned problems, and it is possible to switch the elevator operation control to the display device operation mode by a specific input, and thereby move the car to the floor where the display device is installed. automatically stop,
To provide a control device for an elevator that can improve labor saving by opening a door and checking a display.

[Means for Solving the Problems] An elevator control device according to the present invention includes a switch for switching the elevator to a display device inspection operation mode, and during inspection operation, display device installation floor data stored in a storage device is used. and a control device that controls the running of the car and the display on the display device based on test pattern data for inspection.

(Function) In this invention, during an inspection operation, the car automatically travels sequentially to the floor where the hall display device is installed, stops and stops.
When the door is opened, the test pattern is output to the car white display device during inspection operation, and to the landing display device while the car is stopped. do.

[Embodiment] FIG. 1 is a schematic diagram showing the overall configuration of an apparatus according to an embodiment of the present invention, and FIG. 2 is a circuit configuration diagram thereof. 1st
In the figure and FIG. 2, (1) is the elevator car, (
2) is an elevator control device; 3) is a car white display device provided in the car (1); and (4) is a hall display device provided on a specific floor.

(5) is a CPU for controlling the elevator, and (6) is a ROM.

(7) is RAM, (8) is external 110 interface circuit, (9) is display device inspection switch, (10) is display control CPU, (11) is CPU (5) and display control CPU (10) is a two-bottom RAM for data transfer, and (12) is a ROM that stores test pattern data used during inspection of the display device.

(13) is a RAM, and (14) is an interface circuit with the landing and car display devices (3) and (4).

Next, the operation will be explained according to the flowcharts shown in FIGS. 4 to 6. FIG. 4 shows an example of data processing by the control CPU (5). First, when the program is started, initialization is performed in step S21, and in step S22, for example, the display device installed in the car is inspected. It is determined whether the switch (9) is ON. If this is NO, operation control processing is performed in step S23, input/output processing is performed in step S24, and thereafter this is repeatedly performed to perform normal operation control. If YES in step S22, the process moves to display device inspection operation processing in step S25.

FIG. 5 shows the processing contents of step S25 in more detail. When the display device inspection operation starts, first, in step S31, a test pattern output command to the car white display device (3) is sent to the 2-board RAM. (11) is written in the specified space, and the display control CPU (10) is written in the specified space of these two ports).
The car white display device (3) is controlled by reading various command data written in the RAM (11).

As a result, the car white display device (3) continues to display the test pattern from then on. In step S32, the total m of floors where the hall display devices are installed is read from the memory contents in the ROM (8) as shown in FIG. 3, and then in step S3
In step S3, the installation sequentially reads out the floors, registers each floor read out in step S34 as a car call, and lights up all the corresponding destination floor buttons in the car. This allows the inspection worker inside the car to know on which floor of the building the display device is installed.

Thereafter, in step S35, the first installation issues an operation command to the floor (2F in the example of FIG. 3), and in step 936, the operation control process is performed. The first installation is on the floor with a basket (
After waiting until the door is opened in step S37 after the arrival of 1), in step (38), the stop floor information and the test pattern output command to the hall display device are sent to the 2-boat RAM (11).
) is written in a predetermined space. Car white display device (3)
Similarly to the case for display control CPU (10)
By reading this floor data and command data,
Controls the stop floor landing display device and outputs a test pattern. The control CPU (5) maintains the door open state after outputting the test pattern command in step 33g, but during this time, the operator once gets off the car to the landing and the test pattern is displayed normally on the display device (4). It is possible to check whether the When the door opening button is pressed by the worker who has returned to the car, this is detected in step S39, and the process moves to step S40. In step S40, the hall test pattern output stop command is sent to the 2-port RAM in the same way as above.
(11), thereby controlling the CPU for display control.
(10) stops outputting the test pattern to the display device (4) in the landing hall of the stop floor.

In step S41, it is determined whether the hall display device has been installed on all floors (a total of m floors in FIG. 3) or whether inspection has been completed.
If NO, a door close command is output in step S42, and in the next step S43, an operation command is output for the next installation floor (5F in the example of FIG. 3).

Thereafter, the process returns to step 83B and the same process is repeated. When all installations have been inspected on the floor (up to nF in the example of Fig. 3) and YES is determined in step S41, the process moves to step S44, where the car white display device (
3) The test pattern output stop command to 2-port RAM
(11) is written. Therefore, the car white display device (
3), the test pattern is constantly displayed during the inspection operation, but the display disappears for the first time at this point, and then the process returns to step S22 in FIG. 4 to restore the normal operating state.

FIG. 6 is a flowchart showing the processing procedure of the display control CPU (10), in which initialization is performed in step S50 upon starting the program, and then in step S51 the car white display device test pattern is output. Whether or not a command is output from the control CPU (5) is determined by reading a predetermined space in the two-board RAM (11). If this is NO,
A test pattern output stop command is output to the car white display device (3), and the process proceeds to step S54. If YES, the test pattern data stored in the ROM (12) is sequentially unread in step S53, and the interface circuit (14), the car white display device (
3) and continues displaying the test pattern thereafter.

Next, in step S54, it is determined whether or not a command to output a display device test pattern on the hall side has been issued.

If NO, normal car white display control and hall display control are performed in steps S55 and 35G, respectively, and the process returns to step S51 to repeat the same processing thereafter. However, if YES in step S54, the test pattern data is read out from the ROM (12) in the same way as in the case of the car in step S57, and the test pattern data is read out from the ROM (12), and the The test pattern is outputted to the hall display device (4), so that the predetermined hall display device (4) continues to display the test pattern. Next, in step S5g, it is determined whether a test pattern output stop command has been output, and if YES, the step knob S59 is
to stop outputting the test pattern and proceed to step S51;
If it is O, by directly returning to step S51,
Thereafter, the same process as above is repeated.

As explained above, in this embodiment, when the display device inspection switch is turned on in the car, the installation floor of the hall display device is registered, and the destination floor button in the car lights up to notify the operator. The installation floor is announced, and the device automatically moves up and down to the designated floor and opens the door. In addition, the test pattern is displayed on each display device in the car during inspection operation and at the landing while the car is stopped.

In the above embodiment, the test pattern data to be displayed for inspection is controlled by the RO of the display control c p tr (io).
Although these data are stored in M, the car white display device (3) and the three hall display devices (4) may each have these data. Furthermore, the display device inspection switch (9) is not particularly limited to being installed inside the car, and may be installed at any location.

Furthermore, although only the display device was explained in the above embodiment, a check function such as a hall indicator and a hall lantern can be added to the processing procedure of the control CPU (5), so that a check operation can be performed automatically on all floors one after another. By doing so, the same effects as in the above embodiment can be obtained.

[Effects of the Invention] As explained above, in the present invention, when the display device inspection switch is turned on, the operation of the elevator is switched to the inspection operation mode, and the elevator automatically stops sequentially at the floors where the hall display device is installed. Since the display device can be checked by opening the door, inspection workers do not have to memorize the floor where the display device is installed, and can perform inspection work by simply turning on a switch, increasing work efficiency. be able to. Further, since a test pattern for display inspection is stored in advance in the storage device and displayed on each display device during inspection, omissions in the check can be eliminated.
