The operation of this embodiment will now be described with reference to some examples that occur during normal operation of the elevator 1. When the passenger gets on the car 11 and presses the button on the destination floor, the information is stored in the operation data storage device 202 of the elevator control device 20 via the input device 201, and at the same time, the operation control device 203 receives the input destination. The floor and the current position of the car 11 extracted from the operation data storage device 202 are compared, the moving distance between the two is calculated as the number of pulses of the pulse encoder 16, and the ascending operation or the descending operation is determined. According to this determination, the output device 20
4 outputs a command signal to the drive control device 17. In response to this command signal, the drive control device 17 excites the operation command relay 14 to close the contact 15 of the drive command relay 14 to rotate the motor 13, and the car 11 moves up or down accordingly.

As the motor 13 rotates, a pulse is output from the pulse encoder 16 in accordance with the rotation, and this pulse is input to the elevator control device 20 via the drive control device 17 and the input device 201, and the operation control device 203 before. The input pulse is sequentially subtracted from the calculated number of pulses to calculate the remaining travel distance of the car 11. When the remaining travel distance reaches a predetermined value, the operation control device 203 outputs a deceleration command to the drive control device 17, and then the remaining travel distance becomes 0.
When it becomes, a stop command is output. In response to this stop command, the drive control device 17 de-energizes the operation command relay 14 and opens the contact 15 to stop the motor 13 (car 11). These series of operations are sequentially stored in the operation data storage device 202. Elevator control device 20
The operation data of the elevator 1 is stored in the operation data storage device 202 as described above, and at the same time, the stored data is transferred to and stored in the transfer data storage device 301 of the inspection device 30 by the operation data transfer device 205 in sequence. Go on.

Next, an example of the operation of the inspection device 30 will be described. The inspection determination device 302 of the inspection device 30 makes various determinations using the data transferred to the transfer data storage device 301. As an example of this determination, for example, the time from when the operation command relay 14 in the transfer data is excited until the output pulse of the pulse encoder 16 that is sequentially transferred and stored reaches a predetermined value is measured, and the time is measured. Is compared with a predetermined time to determine whether the operation characteristic of the drive control device 17 is good or bad. If it is determined that the time is abnormally longer or shorter than the predetermined time, the inspection device 30 reports the abnormality to the monitoring center device 40 via the communication device 307 as in the conventional system. .. On the other hand, if the time is within the normal range, the inspection determination device 302 determines that the drive device 17 is normal, and stores the result in the inspection data storage device 304. If the time is not normal but not normal, the inspection / determination device 302
Is stored in the inspection data storage device 304 as “drive control device 17 requires inspection”.

Further, the equipment operation counting device 303 checks the operation information of the operation command relay 14 in the data transferred to the transfer data storage device 301, and counts up the number of operations of conversion from the non-excited state to the excited state. Then, the value is stored in the count data storage device 305. further,
While the pulse input from the pulse encoder 16 is continuously input to the transfer data storage device 301, the device operation counting device 303 integrates the duration as the traveling time of the car 11 and the accumulated traveling time up to that time. The traveling time is stored in the count data storage device 305. In this way
Inspection data storage device 304 and count data storage device 3
In 05, data of inspection results and data of counting results are sequentially accumulated.

Next, an example of the operation of the inspection center device 8 will be described. The collection schedule storage device 87 of the inspection center device 8 stores the inspection devices 3 of all elevators under control.
A schedule (collection interval) for collecting inspection data and counting data stored in 0 is stored. The inspection center device 8 outputs a collection command to the communication device 81 in accordance with the schedule, and thus each inspection device 3
Check data and counting data are collected every 0. That is, the communication device 81 makes a dial call to the inspecting device 30 instructed, and the communication device 307 of the inspecting device 30 concerned.
Is connected by a telephone line to collect each data stored in the inspection data storage device 304 and the count data storage device 305. The inspection data analysis device 82 performs a predetermined analysis based on the collected inspection data.

Here, the analysis by the inspection data analyzing device 82 will be described by way of example. For example, as described above, the time required for the inspection result of the inspection determination device 302 of the inspection device 30 to reach the predetermined rotation of the motor 13 after the operation command relay 14 is excited is not long enough to issue a warning, but is too long. , Or if it is too short, the abnormality is stored in the inspection data storage device 304 of the inspection device 30 in the form of a specific code corresponding to the abnormality. The inspection data analysis device 82 of the inspection center device 8 creates data for displaying the wording "drive control device 17 requires inspection" based on the transmitted code data, and stores this data in the form data storage device 84. Store. If the above time is normal, the data "drive control device 17 is normal" is stored.

Furthermore, the life judging device 83 of the inspection device 30
Judges the collected count data. For example, in the data of the count data storage device 305 of the inspection device 30, the data of the operation number of the operation command relay 14 is compared with a predetermined operation number, and when the former is a value exceeding the latter operation number, the "operation The command relay 14 needs to be replaced ”, and this data is stored in the form data storage device 84. If the number of operations of the operation command relay 14 does not exceed the predetermined number of operations, the form data storage device 84 does not store the data.

As described above, when data is stored in the form data storage device 84 such as "drive controller 17 needs inspection" and "operation command relay 14 needs replacement", these data are stored in the same data as these data. Related data, in the above example, the integrated value of the traveling time is added, and these are stored together in the saved data storage device 85. In this way, when the data collection from all the inspection devices 30 is completed according to the collection schedule, the communication device 86 is stored in the form data and saved data storage device 85 stored in the form data storage device 84 by the signal of the collection end. The stored data stored therein is transmitted to the information center device 9 via the communication device 91.

The information center 9 communicates the form data transmitted from the inspection center device 8 (the form data and the abnormal report data concerned when the inspection device 30 issues an abnormality report to the monitoring center device 40). 94 to the sales office 50. On the other hand, the stored data transmitted from the inspection center device 8 is stored in the database storage device 92 by the processing of the database search and aggregation device 93.

At the business office 50, the form data transmitted from the information center 9 (the form data and the abnormal report data when an abnormal report is made) is received by the communication device 51, and the received data is output to the form. The device 53 prints out. Then, in the output form, data requiring maintenance, such as the above-mentioned “drive control device 17 requires inspection”,
When "Operation command relay 14 requires replacement" is described in the form, the sales office 50 carries necessary tools and replacement parts according to this description, dispatches maintenance personnel to the relevant elevator 1, and describes it in the form. Perform maintenance work according to the specified items. After the work is completed, the maintenance staff fills in the required items for the maintenance work for each item performed on the form, reports the maintenance work to the manager in charge of the owner of the elevator 1, and if necessary, Submits the form and asks for a confirmation stamp.

The operation mainly relating to the normal maintenance has been described above, but the operation other than this will be described below. During the operation of the present embodiment, the inspection determination device 3 of the inspection device 30.
If an abnormality that should be urgently processed in 02 is detected,
The inspection determination device 302 immediately transmits the abnormality report data to the monitoring center device 40 by the communication device 307. In the monitoring center device 40, the communication device 401 receives this, and the elevator monitoring device 402 analyzes the content of the abnormality notification data and displays it. The operator of the monitoring center device 40 sees the display on the elevator monitoring device 402 and performs the same process as in the prior art. The contents analyzed by the elevator monitoring device 402 are transmitted to the information center device 9 by the communication device 403 as form data.

In the office 50, if it is desired to change the data collection schedule, the collection schedule input device 5
Use 4 to enter the changed schedule. The input schedule is transmitted to the collection schedule storage device 54 of the inspection center device 8 via the communication device 51, and the schedule is rewritten. Thereafter, data collection will be performed according to this rewritten schedule.

Diagnostic operation command device 308 of inspection device 30
At a predetermined time on a predetermined day (a date and time when there are no elevator passengers selected)
A command signal for performing an operation (low-speed operation or high-speed operation) necessary for diagnosing the elevator 1 is transmitted to the signal input device 206 of the elevator control device 20. As a result, the elevator control device 20 operates the drive control device 17 according to the diagnostic program to perform the diagnostic operation. The data of the diagnostic operation will be processed in the same procedure as in the case of the normal operation.

Further, the use of the saved data stored in the database storage device 92 of the information center device 9 will be described. For example, at the sales office 50, a person in charge of improving or guaranteeing the quality of elevator service uses the database search / aggregate input device 52 from the database storage device 92 for all elevators at the time of detecting a failure of the elevator drive control device 17. Integrated value of running time,
The number of operations at the time of exchanging the operation command relay 14 and the running time integrated value are searched and required aggregation is performed, and the results are printed out by the form output device 53. Based on the form obtained in this way, the person in charge makes judgments such as preventive measures against similar failures, suitability of the current maintenance interval, and whether or not the product life coincides with the life expectancy at the time of design, and the judgment results. Is reflected in the maintenance work design department and the product design department, which makes it possible to construct a better quality maintenance work system, develop a new product, and improve or improve the current product.
Further, by collecting the abnormality report data and the device replacement information by the database search totalization input device 52, it is possible to appropriately carry out production planning, parts arrangement, etc. in the production department.

As described above, in this embodiment, the operation information of the elevator drive control device 17 is constantly transferred to the inspection device 30 by the elevator control device 20, and the abnormality determination and the device operation counting are performed based on the transferred information. Since the result is processed by the inspection center device 40, transmitted to the sales office 50, and saved in the information center device 9, the status of each elevator is automatically and accurately at a remote location. The maintenance staff does not have to visit each elevator on a regular basis to perform inspections, which significantly reduces the burden on the maintenance staff and identifies the points to be maintained. Therefore, tools and parts can be prepared in advance, and quick and appropriate maintenance can be performed.

In the above embodiment, it is obvious that the inspection center device, the information center device, and the sales office device can be installed in any area (point).

[0034]

As described above, in the present invention, the operation information of the elevator is constantly transferred to the inspection device, the abnormality is judged based on the transferred information, and the cumulative value of the predetermined item is counted, and the result is obtained. Is processed by the inspection center device and stored in the database storage device, so the status of each elevator can be automatically and accurately grasped at a remote location. Since it is not necessary to go to each elevator to inspect it, the burden on maintenance personnel can be greatly reduced, and since the location to be maintained is known, tools and parts can be prepared in advance, Can perform prompt and appropriate maintenance.
