Abstract

PURPOSE:To control operation without the interference with any traffic in a building even if any failure occurs in an observation controller by detecting some failure in the observation controller through a failure detecting device, and selecting an operating pattern at the time of failure through an operating pattern selecting means at the time of failure. CONSTITUTION:An operating pattern of an elevator is computed by the CPU 11a of an observation controller 11, memorized in a memory device 11b, and is transmitted to a group-control controller 21 through serial communication by a transmitting device 11d. Besides, failure on the observation controller is detected by a failure detecting device 12, and is transmitted to the group- control controller 21 as a contact signal through other wiring than the serial communication. A failure signal transmitted from the failure detecting device 12 in the observation controller 11 is detected by the group-control controller 21, and an operating pattern selecting command at the time of failure is sent out to an elevator controller 30. At the time of failure, an operating pattern is selected according to preset time in the clocks which are provided with the group-control controller 21 and the elevator controller 30.

On the other hand, in Japanese Patent Application Laid-Open No. 59-48364, an elevator is devised in which the operation of an elevator is controlled by input from an external device. There is a demand for such human operation control from an external device to be able to be controlled all at once on a CRT by operating a light pen or the like from an elevator supervisory control device.

(Problem to be Solved by the Invention) However, in an elevator control device equipped with a supervisory control device as described above, if a failure occurs in the supervisory control device, patterns such as operation at work, operation at lunch, or operation at clock out can be selected. If the time command was not issued at all, there would be problems such as a shortage of elevators, which would cause passengers to overflow into the halls and paralyze building traffic.

If this is not the case, a built-in watchdog timer will issue a failure signal. (21) is a failure detection signal manual device for manually inputting the failure signal from the failure detection device (11) to the elevator group control panel, and (22) is a failure detection signal input device (21) that detects the failure signal input. The failure detection signal input means (22) causes the failure pattern selection means (23) to issue an operation pattern selection command to the elevator control device (3o) in response to the failure signal from the failure detection signal input means (22). ).

Further, (13) is an operation pattern selection signal output means for outputting an operation pattern selection command from the supervisory control device (11) to the elevator group control panel, and (24) is an operation pattern selection signal output means for outputting an operation pattern selection command from the supervisory control device (11) to the elevator group control panel that receives the operation pattern selection signal. Pattern selection signal human power device (25) indicates operation pattern selection means for outputting an operation pattern selection command in normal times to the elevator control device (30) based on the above-mentioned failure signal and operation pattern selection signal.

FIG. 2 shows a specific example for realizing the basic configuration shown in FIG. 1 above. In the figure, (10) indicates an elevator monitoring panel that transmits an elevator operation pattern selection command signal to the elevator group control panel (20),
This elevator monitoring panel consists of a monitoring control device (11), a failure detection device (12), and a monitoring control device (11) shown in Fig. 1 above.
The elevator is equipped with a display device (14) made of a CRT that is connected to the elevator terminal (1) and displays the status of the elevator, and a human-powered device (15) or a keyboard for specifying display switching.

Here, the above-mentioned supervisory control device (11) is composed of a microcomputer, and works as a central processing unit with CPII (
lla), storage device (11b), transmission device (llc)
and (lid), and the operation pattern selection signal output means (13) in FIG.

2), the elevator car (33) and the counterweight (34) are controlled to move up and down.

Next, the operation related to the above configuration will be explained.

The elevator operation pattern is calculated by the CPLI (lla) of the supervisory control device (11) and stored in the storage device (llb) as elevator operation pattern selection information. The elevator operation pattern selection information stored in the storage device (llb) is transmitted to the group management control device (21) by serial communication by the transmission device (lid). Further, a failure of the supervisory control device (11) is detected by a failure detection device (12), and is sent as a contact signal to the group management control device (21) through a wiring different from serial communication.

The group control device (21) detects a failure signal sent from the failure detection device (12) of the supervisory control device (11) and sends an operation pattern selection command in the event of a failure to the elevator control device (3).

If it is not a failure, proceed to step S4. The process of step S3 is shown in FIG. Note that the process in step S4 is a normal operation pattern selection process, so it is not shown here.

FIG. 4 shows the operation pattern selection process at the time of failure in step S3 of FIG. In FIG. 4, step 531 is performed by the operation pattern selection signal output means (13) of the supervisory control device (11).
It is determined whether there is a traffic pattern selection signal from the station.

If there is a driving pattern selection signal from the driving pattern selection signal output means (13), the process advances to step S32 and the currently running driving pattern is canceled. In step S33, operation control is performed by selecting a pattern according to the clock held within the group management control device (21), rather than executing the operation pattern selection command from the supervisory control device (11).

In the above embodiment, the failure signal of the supervisory control device (11) is transmitted from the failure detection device (12) to the monitoring board (1) by displaying the failure on the lamp on the monitoring desk of the elevator.
0) It will take less time to spread the word and will be more effective.
