However, a dedicated transmission path is provided from a control device for such a plurality of elevators to a remote monitoring device. Therefore, the same number of transmission lines as the number of installed elevators was required.

The present invention has been made in order to solve the above-mentioned conventional problems, and when a failure occurs in one of the elevators at the elevator installation location where a large number of elevators are installed at the same time, common transmission is performed. It can be transmitted to the remote monitoring device in the monitoring room via the road, and detailed information can be obtained in advance about which elevator out of many elevators in the remote monitoring device and what kind of failure has occurred. It is an object of the present invention to provide an elevator remote monitoring system that enables quick response.

The operation of the elevator remote monitoring system configured as described above will be described.
The internal processing of is configured by software using a computer, and the failure monitoring device 12 checks the operation status of each part of the elevator drive mechanism by an operation status check routine as shown in FIG. The operation state check routine by the failure monitoring device 12 will be described. It is determined whether or not a failure has occurred (step S1). If a failure has occurred, the failure code of the corresponding mechanism of the operation state check routine is determined. Set to failure data (step S2).

This failure data is sequentially transmitted to the elevator remote monitoring device 15 side through the data transmission device 13, the local area network 25 and the relay transmission device 26, and the transmission line 14 shown in FIG.

You can also

FIG. 4 shows a more detailed configuration of the remote monitoring system for the elevator, and shows a detailed configuration of the failure monitoring device 12 and the failure data display device 19 shown in FIG.

The failure monitoring device 12 of each elevator control device 11 includes a failure analysis unit 20, a failure data creation unit 21, and an elevator operation state creation unit 22. The failure data display device 19 of the remote monitoring device 15 includes a failure data translation unit 23 and a failure data display unit 24.

The main function of the failure analysis unit 20 is to check whether each signal input is suitable for the current operating state of the elevator or not, and a processing routine for detecting a brake abnormality as an example of the processing. Will be described with reference to FIG.

It is determined whether the elevator control device 11 has issued a brake release command to the brake (step S3).

If a brake release command is output here, whether or not the brake is actually released in response to the brake release command is determined by a signal from a brake state check contact attached to the brake. It is determined (step S4).

If it is determined that the brake has not been released, it is determined that the brake is abnormal if this state has continued for a predetermined time or more, and the failure data generator 2
A failure code indicating a brake abnormality is output to No. 1 (steps S5 and S6).

On the contrary, in the case where the brake release output is not detected in step S3, if the brake release is detected on the contrary, it is judged that the brake abnormality is still caused after a certain period of time has passed, and a failure occurs. A brake abnormality code is set in the data creation unit 21 (step S
7, S5, S6).

When there is a set of failure codes from the failure analysis unit 20 as described above, the failure data creation unit 21 reads the elevator operation state data from the elevator operation state data creation unit 22 and combines them to create a failure code. I do.

FIG. 6 shows an example of the elevator operating state data. In this embodiment, the elevator operation state data is 8-bit data of 1 byte, and each bit indicates 1 or 0 to indicate 8 types of states.

The generated fault data is then transmitted to the data transmitter 13 and the local area network 25 shown in FIG.
The data is transmitted to the data receiving device 16 of the remote monitoring device 15 via the relay transmission device 26 and the transmission line 14.

On the remote monitoring device 15 side, the failure data received by the data receiving device 16 is temporarily stored in the failure data storage device 17. An example of the data structure of the failure data storage device 17 is shown in FIG. The failure data storage device 17 writes the input failure data in the failure data storage area in order from the first address, and adds one write pointer each time one failure data is written in the failure data storage area. The state shown in FIG. 7 is a state after writing three pieces of fault data. When the fault data storage area is full of fault data, the fault data storage device 17 clears the write pointer to 0 and returns to the beginning. Write from address.

The failure data analyzer 18 reads the failure data using the read pointer of FIG. 7, adds the read pointer by one each time one failure data is read, and reads the value of the read pointer and the value of the write pointer. Continue reading until the value matches. FIG. 7 shows a state in which the failure data analyzer 18 has not yet read any failure data.

FIG. 8 shows an example of the judgment of the failure data by the failure data analyzer 18. First, it is determined whether the failure data read from the read pointer corresponds to a serious failure code (step S8).

If it is determined that the code indicates a serious failure, a sounding instruction for a failure occurrence alarm and a failure data display instruction are immediately output to the failure data display device 19 (step S11).

If the failure code is not a code indicating a serious failure but a code indicating a minor failure registered in the failure data analyzer 18, the number of minor failures is counted, for example, three times within one hour. When a minor failure has occurred, it is regarded as equivalent to the occurrence of a major failure, and the processing in step S11 is performed (steps S9 and S10).

The failure codes include not only a code indicating a mechanical failure of the elevator but also a code indicating a power failure. Therefore, if a person is trapped in an elevator of a building without self-control function, a warning must be issued and rescue must be taken immediately. Therefore, the failure data analyzer 18 performs not only the serious failure occurrence processing with the simple routine shown in FIG. 8 but also information on the facilities of the building in which the elevator is installed as a determination factor.

When the failure data analyzer 18 determines that a serious failure has occurred in this way, the failure data is input from the failure data storage device 17 to the failure data translator 23 of the failure data display device 19, where, for example, The fault code and the elevator operating state data as shown in FIG.
Output to. Further, if the failure data analyzer 18 gives a sounding command of a failure occurrence alarm, it outputs an alarm sounding instruction to the failure data display unit 24.

The failure data display section 24 displays the data on a CRT or a printer, and generates an alarm sound from a speaker or the like. In the output example of the failure display shown in FIG. 9, the name of the building in which the failure has occurred, the number of the failed elevator, the date of occurrence of the failure, the location of the failure, the operating state, and the like are displayed. Further, in the case of this output example, it is clear that there is a car call, so it is also clear that passengers are confined in the elevator.

In FIG. 7, another call pointer is provided, and when the failure data is translated, the display pointer is issued by performing the translation work until the read pointer matches the read pointer used by the failure data analysis device 18. It is possible to display all the failure data that occurred before the specified time. By doing so, it is possible to know the circumstances leading up to the failure before the time when the serious failure occurred, and it is possible to obtain important information for investigating the cause of the failure.

Thus, according to the elevator remote monitoring system of this embodiment, if a plurality of elevators are installed in the same single elevator installation location and an abnormality occurs in any of the elevators, the elevator for that elevator is used. The fault information of the elevator can be transmitted from the control device to the remote monitoring device via one common transmission line with the local area network.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, in the above embodiment, the failure data of the elevator is stored in the failure data storage device 17 provided on the remote monitoring device 15 side.
Is provided on the side of the elevator control device 11, and when the failure monitoring device 12 on the side of the elevator control device 11 detects a failure, the failure data is sent to the remote monitoring device 15 side via the transmission line 14, and at the same time to the elevator control device 11 side. Failure data is sequentially stored in the provided failure data storage device 17,
When the failure data analysis device 18 of the remote monitoring device 15 analyzes the failure data, if the history of the failure of the elevator is required, the transmission of the past failure data to the corresponding elevator control device 11 is requested. Data storage device 1
It is also possible to have a configuration in which the failure history is read from 7 and sent to the remote monitoring device 15 side, and analyzed by the failure data analysis device 18.
