Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator abnormality monitoring device, and more particularly to an elevator abnormality monitoring device suitable for identifying an abnormal portion of an elevator.

[0002]

2. Description of the Related Art A conventional elevator abnormality monitoring device is provided with a means for performing a warning operation when an elevator abnormality is detected, or with a timer composed of software provided between the abnormality detection means and the information transmission means. A means for performing a warning operation only when the abnormal state of the elevator has continued for a certain period of time or more has been adopted.

[0003]

The former means of the above-mentioned prior art performs a warning operation if, for example, an abnormal condition is satisfied even for a moment, so if an elevator abnormality / recovery of the same content repeatedly occurs in a short time, Each time, the same information is sent to the central monitoring device, resulting in wasted telephone usage charges and labor costs on the central monitoring device side.

As a means for solving this problem, the latter means of the above-mentioned prior art is used, and the alarm issuing operation is performed only when the abnormal state of the elevator continues for a certain period of time or more. For example, if an elevator abnormality / recovery occurs within a short time less than the above fixed time,
There was a problem that the notification operation could not be performed.

An object of the present invention is to solve the above-mentioned problems in the prior art, to reliably detect even if an elevator abnormality / recovery occurs in a short time, and to uselessly issue a repeated abnormality. An object is to provide an elevator abnormality monitoring device that does not require operation.

[0006]

In order to achieve the above object, the present invention provides an elevator control panel for controlling the drive of an elevator servicing multiple floors, and an elevator control panel connected to this elevator control panel. Abnormality detection means that constantly monitors the state and detects that an abnormality has occurred in elevator control, a timer that detects that the abnormality of the elevator detected by the abnormality detection means has continued for a certain period of time, and an abnormality with this timer In an elevator abnormality monitoring device having information transmission means for transmitting continuation to the central monitoring device when continuation is detected, recording means for sequentially accumulating this abnormality information when the abnormality detection means detects an abnormality, and this recording means Output means for outputting the abnormality information stored in the information transmission means to the information transmission means under a predetermined condition.

[0007]

[Function] When the abnormality detecting means in the elevator abnormality monitoring device detects an abnormality in the elevator, the abnormality information is sequentially stored in the recording means, and even if the abnormality / recovery of the elevator occurs in a short time, this is surely recorded. deep. Further, since the timer outputs information to the information transmitting means only when the abnormal state of the elevator continues for a certain period of time or more, unnecessary alarming operation need not be performed when the same failure occurs repeatedly.

Further, since the abnormality information stored by the recording means is output to the information transmitting means and transmitted to the central monitoring device collectively when a certain condition, for example, the number of times of detection of the abnormality reaches a prescribed number, the timer is Even if it fails to operate, the abnormality can be reported to the central monitoring device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an elevator abnormality monitoring device according to an embodiment of the present invention. In the figure, 1 is a control panel for controlling the elevator, 2 is an elevator abnormality monitoring device for monitoring the control state of the elevator, 3 is a general communication line such as a telephone line, 4 is a central monitoring device, and 1A is an elevator control panel 1. It is a connection line for taking in the generated control signal to the elevator abnormality monitoring device 2. Reference numeral 2a is a failure detection processing unit that analyzes a control signal of the elevator taken in from the elevator control panel 1 to the elevator abnormality monitoring device 2 and detects a failure. 2b is that the failure of the elevator detected by the failure detection processing unit 2a has continued for a certain period of time. A timer by software for detecting 2c is an alarm processing section for transmitting predetermined information in the elevator abnormality monitoring apparatus 2 to the central monitoring apparatus 4 via the communication line 3, and 2d is an abnormality detection recording processing section. .

Next, the operation of this embodiment will be described. Elevator control signals are constantly exchanged between the elevator control panel 1 and the elevator abnormality monitoring device 2 through the connection line 1A. In the failure detection processing unit 2a in the elevator abnormality monitoring device 2, the elevator control panel 1
Control signals sent from are constantly monitored and analyzed to detect failures. When the failure detection processing unit 2a detects a failure of the elevator, the failure information is output to the timer 2b that detects that the failure has continued for a certain period of time. At the same time, the failure information is also passed to the abnormality detection record processing section 2d.

Now, the operation of the abnormality detection recording processing section 2d will be described. When the abnormality detection record processing unit 2d receives the elevator failure information from the failure detection processing unit 2a, the date and time data at that time is added, and this information is sequentially stored. At this time, the number of times of failure detection is also counted. An upper limit is set for the number of times of failure detection to be stored, and when the stored information reaches a certain prescribed number, this information is output to the alarm processing unit 2c.

Next, the operation of the timer 2b for detecting that the failure has continued for a certain time will be described. Timer 2b
Starts operation when the failure information of the elevator is input from the failure detection processing unit 2a and monitors the failure duration time.
When the failure is recovered within a predetermined time, the failure information input signal is cut off, the timer 2b is reset, and the initial state is restored. Further, when the failure does not recover within the determined time, the timer 2b times up and the failure occurrence information is output to the alarm processing unit 2c. After the timer 2b has timed up and the failure occurrence information is output to the alarm processing unit 2c, when the failure detection processing unit 2a detects that the failure has been recovered, the input signal is cut off and the timer 2b operates. The alarm processing unit 2 is reset by this reset.
Information on failure recovery is output to c. The notification processing unit 2c judges that this abnormality is an abnormality already reported,
Report the restoration.

When the alarm processing unit 2c inputs information from the timer 2b and the abnormality detection recording processing unit 2d, the alarm processing unit 2c starts the alarm processing for transmitting the information to the central monitoring apparatus 4 via the communication line 3. That is, the alarm processing unit 2c first performs a dialing process on the telephone number of the central monitoring device 4 which is registered in advance in a storage unit (not shown) in the elevator abnormality monitoring device 2. When the central monitoring device 4 and the elevator abnormality monitoring device 2 are connected, the alarm processing unit 2c performs a predetermined procedure and then transmits the input information. Here, the alarm processing unit 2c is the abnormality detection record processing unit 2d.
When the information to be transmitted is input, only that information is transmitted. However, when the information to be transmitted is input from the timer 2b, in addition to the information, the information that the abnormality detection recording processing unit 2d has accumulated so far. Also transmitted. Of course, when there is no information stored in the abnormality detection recording processing unit 2d, only the information input from the timer 2b is transmitted. Once the information has been transmitted,
The alarm processing unit 2c ends the connection with the central monitoring device 4.

When the elevator abnormality monitoring device 2 and the central monitoring device 4 are connected to each other in response to a connection request from the central monitoring device 4, the central monitoring device 4 detects the abnormality detection record processing section 2d.
The information that has been stored up to now can be fetched via the report processing unit 2c. In this case, when the alarm processing unit 2c has transmitted the information stored in the abnormality detection recording processing unit 2d to the central monitoring device 4, the abnormality detection recording processing unit 2d clears all the information and returns to the initial state.

[0015]

As described above, according to the present invention,
When the abnormality detection means detects an abnormality in the elevator,
Since there is a recording means that stores this abnormality information in sequence,
Even if an elevator malfunction or restoration occurs in a short time, this can be reliably grasped. Further, since a timer is provided between the abnormality detecting means and the information sending means to notify the abnormality only when the elevator abnormality continues for a certain period of time or more, it is wasteful when the same failure occurs repeatedly. Eliminates the need to perform alerting operations. Further, since the information stored in the recording means is collectively sent to the central monitoring device by the information sending means based on a predetermined condition such as a prescribed number of times, even if the timer does not operate, the abnormality is centralized. The monitoring device can be reported.
