When the antenna 22 of the maintenance service car 12 receives the call signal, a wireless telephone line is automatically formed between the antenna 21 and the antenna 22 by the communication control circuit of the wireless telephone 7.

Therefore, failure information indicating that the elevator is stopped in the middle of the floor in an unstartable state and the status data of (a) to (g) are transmitted from the terminal monitoring device 1 to the wireless telephone 7 via the telephone line 18. and transmitted via the wireless telephone line.

As mentioned above, the terminal monitoring device 1 sends failure information and (a)
In the monitoring center 6 to which the status data of ~(g>) is transmitted, these failure information and status data are input to the inference unit 6f via the communication control unit 6a, and the inference unit 6f converts these inputs into knowledge data. It is compared with the rules stored in the storage unit 6h1.

Here, state data (a) to (g) have the following content (a)'
〜(g)′.

(a)'The elevator is stopped within the floor level range.(b)'The number of floors the elevator stops at is the 1st floor.(C)'The elevator door is open.(d)'The door on the hall side is open ( e)'Each door is fully opened (f)'There is an upward call (g)'The inference unit 6f that the 1st floor up call button is pressed has the above status data (a)' to ( g)' and the rule of knowledge data storage unit 6h1, it grasps the state that "the elevator is stopped on the first floor with both doors fully open", and also stores this state and the state data (f )
Based on '(g)', it is determined that the cause of the "unable to start" abnormality is that the up call button in the first floor hall remains on.

Next, the inference unit 6f inputs the building number, the type of abnormality (unable to start), the current state of the equipment (the elevator is stopped on the first floor with both doors fully open), and the cause of the abnormality (the call button for raising ill hall). (Continuation of ON state) is stored in the storage unit 6b, and the abnormal history data storage unit 6h2 and building data 6 are stored in the storage unit 6b.

from the antenna 21 to the maintenance patrol service car 1 via
A radio wave 2 for calling the wireless telephone 7 of No. 2 is transmitted. Then, in the same manner as in the case of a call from the terminal monitoring device 1, a wireless telephone line is formed between the antenna 21 and the antenna 22 by the communication control circuit of the wireless telephone 7, and the data displayed on the display section 6d is monitored. It is transmitted from the center 6 to the wireless telephone 7.

In this way, the terminal monitoring device 1 indicates to the radio telephone 7 of the maintenance patrol service car 12 that is patrolling the area including the building 13 that the elevator is stopped in the middle of the floor in an inoperable state. Failure information and status data are transmitted from the monitoring center 6, as well as data such as the current status of the equipment, cause of abnormality, and abnormality history data obtained by the inference section 6f.

Various data transmitted to the radio telephone 7 in this way is converted into signals for the personal computer 9 by the modem 8, inputted to the personal computer 9, analyzed and processed, and information on the location of the building 13 and failures of elevators. Analysis data including the state is displayed on the display device 10 and printed on the printer device 11.

On the other hand, if the inference section 6f determines that the cause of the abnormality cannot be inferred based only on the input state data, the inference section 6f instructs the data request section 6g to input further necessary data. .

Therefore, the data requesting section 6g imports the requested data from the elevator device 14 to the abnormal state data detecting section 1a of the terminal monitoring device 1 via the communication control section 6a, the telephone line 19.18, and the communication control device 2. command something.

The data fetched in response to this command is transmitted from the abnormal state data detection section 1a to the inference section 6 via the communication control device 2, the telephone line 18, 19, and the communication control section 6a of the storage section 1b.
f. Therefore, the inference unit 6f again infers the cause of the abnormality based on the obtained new data.

To give an example of such a data request, without accurate data on the opening and closing of elevator doors, it may not be possible to infer the cause of an elevator abnormality.

That is, since the first data transmitted regarding the opening and closing of the door relates to the instantaneous state of the door, it cannot be determined based on the first data alone, considering the case where the door is closed or opened. In such a case, the inference section 6f
will request data on the open/closed state of the door over time (for example, at every predetermined time).

In this way, the display device 10 and printer device 11 of the maintenance patrol service car 12 that is patrolling the area including the building 13 are shown on the elevator device 14 of the building 13 where the failure has occurred.
Data required for repair, building location, elevator model name, current status, abnormality type, abnormality cause, various reference data, etc. are displayed or printed.

In this case, the service technician in the maintenance patrol service car 12 found that the elevator system 14 of the building 13 had stopped on the first floor with both doors fully open, and that the cause of this was 1.
Since it is possible to accurately ascertain that the up call button in the floor hall remains on, the user can quickly carry out repairs by carrying the necessary tools for repair and going directly to the first floor pole.

In addition, the factor analysis by the inference unit 6f may be insufficient,
If multiple causes of the abnormality are displayed and the cause cannot be determined accurately, a dialogue is conducted between the monitoring center 6 and the personal computer 9 of the maintenance service car 12.
It is possible to sort out the causes of abnormalities.

In this manner, according to the embodiment, the state and cause of failure or abnormality in equipment and various data necessary for repair are displayed or printed on the display device 10 and printer device 11 of the maintenance patrol service car 12. Therefore, even if you are not a skilled service engineer, you can accurately and quickly service equipment. In addition, the type of abnormality and the cause of the abnormality are displayed, as well as the abnormality history data of equipment, building data, and even the data of the countermeasure personnel, allowing for even more detailed responses to equipment abnormalities. It becomes possible to do this.
