It is also possible to detect abnormalities such as self-looping due to program abnormalities.
- An abnormality in the execution order of the arithmetic processing may occur due to an abnormality in the microcomputer or the program, but if there is no abnormality, the first factor is that the interrupt operation does not end within the operation cycle time (the operation time Over).
- the calculation time over does not normally occur, but occurs due to a temporary increase in the calculation time, for example, when the call button is operated many times and the call scan calculation takes a long time.
- the calculation time gradually increases as the software is modified or improved, and the calculation time may be exceeded.
- an abnormality in the execution order of the arithmetic processing can be detected earlier, and the occurrence of a secondary failure can be prevented. And reliability is improved.
- control device main body 206 sets a pattern of the processing information at every predetermined calculation cycle. Since it is possible to check for errors, it is possible to constantly monitor for abnormalities, further improving reliability.

- the operating states recorded as history include, for example, CNT value, date, running / stopped state, running direction, departure floor, current floor, destination floor, number of calls, TBL [0] to [9], and the like.
- one abnormality is recorded as one TIME data (history data). Further, the TIME data is stored for 16 times (TIME [0] to [15]), and when it exceeds 16 times, the latest TIME data is stored and the oldest TIME data is deleted.
- the CNT value is a value that is used to create data that increments each time an interrupt operation is performed and calculate the time at which an abnormal processing sequence occurs from the difference from the CNT value at the time of inspection.
- FIG. 40 is a flowchart showing the flow of the history calculation in FIG.
- the history storage address is calculated from POINT and BUF (step S32)
- the data of the operating state of the elevator is stored (step S33)
- the PO history is stored for the next history.
- INT is updated (step S34).
- step S35 it is confirmed whether or not POINT has reached 16 (step S35), and if not, the history calculation is terminated.
- the POINT reaches 36
- the POINT for the next history is returned to 0 (step S36), and the history calculation ends.
- the TIME data when an abnormality occurs in the execution order of the arithmetic processing is stored. This can be used to prevent the occurrence beforehand and to determine the cause of the abnormality. In addition, by checking the TIME data when an error occurs, it is possible to reduce the time required to recover from a failure.
- the history data recorded by the history calculation is not limited to the above example. However, as the history data, a combination of at least one of the data of the traveling / stop state of the car, the traveling direction, the departure floor, the current floor, the destination floor, and the number of calls and a pattern of processing information is used. Is preferred. Embodiment 21.

- Embodiments 17 to 20 show examples in which the present invention is applied to an elevator control device that controls the basic operation of a car, that is, an operation control device.
- the present invention is applied to an elevator control device that detects an abnormality such as overspeed and shifts the elevator to a safe state, that is, a safety device.
- the safety device can be provided separately from the control panel, and may be mounted on a car, for example.
- the main rope 2 13 is wound around the drive sheave 2 11 a of the drive device 2 1 1 and the deflector 2 1 2.
- the car 2 14 and the counterweight 2 15 are suspended in the hoistway by the main rope 2 13.
