Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for monitoring elevator failures.

When an elevator malfunction occurs, a device is used that automatically reports this to a central monitoring center via a telephone line.

However, this device detects and reports only elevator failures such as passenger trapping failures and unusable failures. Therefore, special techniques are required to discover the cause of the failure, and a long time must be spent on troubleshooting. If you try to report many abnormalities and their locations, the capacity of the communication line will increase significantly. In addition, the frequency of notifications increases, and the monitoring center's response is delayed.

This invention improves the above-mentioned problems by detecting multiple failure signals, aggregating them and reporting them to a monitoring center, and storing these failure signals to prevent an increase in communication line capacity and prevent failures.

Next, the operation of this embodiment will be explained.

Elevator control power supply is abnormally high, signal (a) is rHJ
When this happens, the control power supply abnormality signal (2aa) ri FHJ
becomes.

At this time, the output of the intercom button (2A) in the car becomes [J,
The passenger confinement signal ('2H) which is the output of the OR game) ('2H)
2Ha) becomes rHJ. Also, if the door does not open even though the car call is registered, contact (c) closes and contact (a) opens, so A, ND game) (2B)
If this continues for a predetermined period of time, the output of the timer (2J) will become rHJ, and the visitor confinement signal (2H) will be output.
a) becomes "H". OR gate (2E) when the flower is registered or the car driving direction is fixed.
The output of is rHJ, and if the car does not run in this state, the output of p, ND game) (2C) will be t[. If this continues for a predetermined period of time, the output of the timer (2K) becomes rHJ, and the unusable failure signal (2Ia), which is the output of the OR gate (2nd), becomes FT (J. When the power supply abnormality continues for a predetermined period of time, the outputs of the timers (2L) and (2M) become rHJ, and the unusable failure signal (2A) becomes rHJ.

If the car is not within the landing error and is stopped, AN
The landing error outside stop signal (2
Da) becomes fj. When the car is in the floor alignment operation, the wood alignment operation signal (21) becomes rHJ. Even when the car reaches the landing position, the car continues to run at a very low speed, and when this continues for a predetermined period of time, a long-term slow speed continuation signal (2N) is output from the timer (2N).
Na) becomes "H". When the temperature of the hoisting motor becomes abnormal, the motor temperature rise detection signal (2n) becomes rHJ. If the door closing operation is repeated one time or the load when closing the door becomes overloaded, the door closing abnormality signal @ (2Fa), which is the output of the OR game) (2F"), becomes "H". If the door opening operation is repeated or the load when opening the door reaches an overload, the O
P open abnormality number (2Ga) required by the output of R gate (2G)
becomes "H".

The fault signals (2a) detected in this way are stored in the fault storage device (8) in the order of occurrence.At the same time, the floors where the fault has occurred are also stored in the floor storage device (7) in the order of occurrence. , the failure signal (2a) is input to the failure aggregation device (3) and aggregation processing is performed.In other words, the passenger confinement signal (
2Ua) is output as a passenger entrapment failure report command signal (3aa). Now, if the control power supply and the monitoring device power supply are normal, the output of the OR gate (3J) becomes rHJ, and at this time, when the unavailable failure signal (2nd a) becomes rHJ,
The unusable failure notification command signal (3Ka) becomes rHJ.

When the car stops outside the landing error, performs the floor alignment operation, or runs at slow speed for a long time, respectively, a predetermined number of times within a predetermined time, the outputs of the counters (3A) to (3C) each become rHJ,
The output of OR game) (3G) is rHJ, and the output of AND game) (3L) is the implantation abnormality report command Ig (3
La) is the 0 motor temperature rise detection signal (2n
) becomes rHJ, the motor temperature abnormality notification command signal (3Ha), which is the output of the AND gate (3M), becomes rHJ. When the door close abnormal state or the door open abnormal state occurs a predetermined number of times within a predetermined time, the counter (3D), C3E
) output is rHJ, and OR gate (3H)
The output of the AND gate (3N) becomes rHJ, and the door abnormality notification command signal (3Na) which is the output of the AND gate (3N) becomes rHJ.

Also, whether the monitoring device power supply abnormality signal 0 becomes rHJK,
When the output of the timer (3F) becomes rHJ after a predetermined time has elapsed since the control power supply abnormality signal (2aa) became rHJ,
The monitoring system abnormality reporting command signal (3Ia), which is the output of the OR gate (3), becomes rHJ.

In this way, the failure signal (2a) is aggregated into a notification command signal (3a), which is input to the notification device (4).

The notification device (4) transmits the notification command signal by well-known means.
The contents will be reported to the monitoring center via the telephone line. Since the number of notification command signals (3a) is smaller than the number of failure signals (2a), an increase in the number of power line valleys t can be prevented.

The monitoring center staff member who received the notification goes to the machine room of the elevator in question, and by operating the selection switch (9), selects the fault signal and the floor where it occurred from the storage device (7), (81K). Display 00 and fault indicator (II
). At this time, select the selection switch (
The latest data is sent from the terminal (a) of 9), and the latest data is sent from the terminal (b) below.
l ~ (Past data is obtained as you reach Tsukasa.

When the reset switch (12) is operated, recorded contents that are no longer needed are erased to prepare for new recording.

In addition, when the notification trial switch (5) is operated, the notification device (4) will notify that fact, so the notification device (4)
and can test telephone lines.

In addition, if the control power supply or the monitoring device power supply becomes abnormal,
ND Gu) The way of output of (3J) is rL-1, and AN
D game) (3K) to (3N) output barLJ, and no notifications other than the passenger entrapment failure notification command signal (3aa) are generated, thereby preventing non-copying notifications.

Gao, it is also possible to implement it as follows○(7)
The storage devices (7) and (8) are supplied with batteries as a power source during a power outage to retain their memories. In addition, non-volatile memory such as core memory, magnetic bubble memory, electrically writable memory, etc. is used.

(b) Print out records of failures and abnormalities on recording paper.

(1) Signals from the elevator control panel are taken in by serial transmission from the central processing unit in the control panel.

(The signal from the elevator control panel will be taken directly from the bus of the central processing unit in the control panel.)

(9) Selection of the display contents on the display (1) and (1) is made so that the display contents are automatically switched sequentially without using the selection switch (9).

(The floor where the failure occurred is determined by calculation from the direction signal obtained from the control panel and the signal from the floor selector.)

As explained above, in this invention, a plurality of failure signals are reported to the monitoring center and one is stored in the storage device, so that the cause of the failure can be easily discovered.

Furthermore, since the failure signals are aggregated into a smaller number and reported, it is possible to prevent an increase in telephone line capacity and to facilitate the monitoring center's response.
