Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for displaying the state of an elevator on a display device and monitoring it.

[0002]

2. Description of the Related Art As a device for displaying the status of an elevator, a CRT has come to be used as disclosed in, for example, Japanese Patent Application Laid-Open No. 62-105881. On the other hand, an elevator monitoring device using a personal computer (hereinafter referred to as a personal computer) has been considered because of its low price. In the case of this elevator monitoring device using a personal computer, a monitoring program is stored in the hard disk device, and when the device is started, this program is read out to the RAM of the personal computer so that the CPU performs the calculation. It is automatically started up.

Further, when the system function is lost due to software runaway or the like, when the abnormality detecting device detects an abnormality, its output is input to the reset circuit of the system,
It is also considered to construct an automatic reset device that automatically restarts.

FIG. 5 is an overall configuration diagram showing a conventional elevator monitoring device. In the figure, (1) is an elevator control device that controls the elevator, (2) is a monitoring main control unit that is connected to the elevator control device (1) and monitors the elevator state, and (3) displays the elevator state. A display device composed of a CRT, (4) an input device composed of a keyboard connected to the monitoring main control unit (2), (5) an abnormality detection device for detecting an abnormality of the monitoring main control unit (2), (6) Is an abnormality alarm device that operates a buzzer, an indicator light, etc. when an abnormality is detected.

In the elevator monitoring device configured as described above, the monitoring main controller (2) inputs the elevator status from the elevator controller (1) and displays it on the display device (3). . Input device (4) is the monitoring main controller
The output is sent to (2) to switch the display screen of the display device (3) or input elevator operation control information. When the operation control information is input to the monitoring main control unit (2),
Executes monitoring calculation to control elevator operation.

When an abnormality occurs in the monitoring main control unit (2), the abnormality detection device (5) outputs a reset signal to output the monitoring main control unit.
Reset (2). At the same time, the abnormality alarm device (6) operates to warn of the abnormality of the monitoring main control unit (2).

[0007]

In the conventional elevator monitoring device as described above, when an abnormality is detected in the monitoring main control unit (2), the abnormality is alarmed and the monitoring main control unit is detected.
Since (2) is automatically reset, in the case of a failure that cannot be recovered by automatic reset, automatic reset will be repeated. For this reason, the buzzer, indicator lamp, etc. warn of an abnormality when an abnormality is detected, and after reset, return to normal notification,
In addition, there is a problem that the abnormality and the normal are repeated, such as an abnormality alarm. Especially in the case of an abnormal buzzer, the noise does not stop and the noise continues.

The present invention has been made to solve the above problems, and it is an object of the present invention to provide an elevator monitoring device capable of preventing repetition of an abnormal alarm due to automatic reset.
