The present invention is not limited to the embodiment. The components of the embodiments described below include portions that can be replaced and easily replaced by those skilled in the art, or portions that are substantially the same.
Generally, in maintenance inspection work of an elevator, an approximate time (work period) for inspection is set at each site where an elevator to be inspected is installed. The monitoring center sets a safety confirmation time by adding a predetermined time to the work period. If the contact of the end of the check is not received by the time of the security check, the security check is performed. However, sometimes the work has to be done beyond the work period.
In the present embodiment, when a contact is made that the check has not been completed even when the security check time comes, the extension of the security check time is automatically repeated twice as many times as necessary. And, for the first time, only the extended case is contacted to the administrator. A maintenance worker (hereinafter referred to as a maintainer) is also contacted according to the work situation for the second time. Then, when the contact is made when the safety check time arrives and the inspection is not completed, the contact is made not only to the administrator and the maintenance staff but also to the maintenance staff (the maintenance staff in the vicinity) if the maintenance staff is present in the vicinity.

Here, when each button is pressed, the corresponding data (dynamic data) is transmitted to the maintenance manager 330. Fig. 4(c) shows an example of information contained in the transmitted dynamic data 430.
As shown in the figure, the dynamic data 430 includes a terminal ID431, a maintainer ID432, a dynamic 433, a work plan ID434, a site ID435, a time 436, position information 437, and return plan information 438.
The terminal ID431 is information that determines the self maintainer mobile terminal 230. The maintainer ID432 is information for identifying the user of the maintainer mobile terminal 230, i.e., the maintainer 250. This information is registered in advance in the maintainer mobile terminal 230.
The motion 433 is information of a motion set via the motion setting area 412 of the motion setting screen 410.
The work plan ID434 and the site ID435 are the work plan ID512 and the site ID of each of the work plans associated with the set dynamics. Time 436 is information in which dynamic time is set. The position information 437 is position information in which a dynamic time point is set. The return plan information 438 is information relating to the return plan set via the return plan setting screen 420.
[ dynamic history DB ]
Next, the motion history DB343 will be described. The dynamic history DB434 is a database for recording the dynamics of the maintainer 250 generated based on the dynamic data 430. The motion management unit 333 receives the motion data 430, and when there is a change in motion, additionally registers a new record in the motion history DB 232.
As shown in fig. 5, each record of the dynamic history DB343 includes maintainer specifying information 531, dynamic information 532, a work plan ID533, site specifying information 534, time 535, and position information 536.
The maintainer identifying information 531, the work plan ID533, and the site identifying information 534, when receiving a new dynamic input, are the same as the same name information of the corresponding work plan information. The above information is generated based on the maintainer ID432, the work plan ID434, and the site ID435 in the dynamic data 430.
[ maintainer status data ]
Next, the maintenance person status data 344 generated by the maintenance person status management unit 334 will be described. The maintainer status data 344, as described above, is the most up-to-date status data of the manager 250. The maintainer state data 344 is updated each time the maintainer state managing unit 334 receives the dynamic data 430 via the transmitting/receiving unit 331 and the dynamic managing unit 333. The work schedule DB342 is also referred to when updating. In which the record with the end/stop flag 516 set is ignored.
As shown in fig. 6, the maintainer status data 344 includes maintainer identifying information 541, a current status 542, location information 543, a safety status 544, a current field name 545, a next field name 546, a safety confirmation time 547, a set extension number 548, and an auto extension number 549.
Upon receiving the dynamic data 430 registered as the departure dynamic state 433, the serviceman specifying information 511 is newly generated for the serviceman ID 432. The maintainer state managing unit 334 updates the other information each time the dynamic data 430 including the maintainer ID432 is received.
The current status 542, the location information 543, and the current field name 545 are registered based on the dynamics 433, the location information 437, and the field ID435, respectively.
The security state 544 is logged with the security state of the maintainer 250. In the present embodiment, the registration is normal before security confirmation time 547.
The next field name of the field determined by the current field name 545 is registered in the next field name 546. The maintenance-person state management unit 334 registers this information with reference to the work schedule DB 342. When there is no next job plan, no log-in is made.
For example, if the current status 542 is before-job, the safety check time for checking the arrival of the safety check time information 515 registered in association with the next field name 546 is registered. When the user is entering, a security confirmation time for confirming the end is registered in the security confirmation time information 515 registered in association with the current field name 545. When the current state 546 is completed and the next field name 546 is registered, the security check time for checking the arrival of the information 515 registered in association with the next field name 546 is registered. On the other hand, when the next field name 546 is not registered, nothing is registered.
Further, each time the extension is set in the serviceman moving terminal 230, the safety confirmation time 547 is changed to a value increased by a predetermined increment Δ Ts.
The set extension times 548 and 549 are counters of extension times. When safety confirmation timing 547 is extended under the instruction of serviceman 250, the counter of the set extension count 548 is incremented by 1. When the maintenance person status manager 334 automatically extends, the automatic extension number 549 counter is incremented by 1.
[ dynamic configuration reception processing ]
Next, the flow of the dynamic setting reception process when the maintainer 250 receives the dynamic setting by the maintainer moving terminal 230 will be described with reference to fig. 7. The present process starts when a dynamic setting request is received from the maintainer mobile terminal 230.
Upon receiving the dynamic setting request, the dynamic management unit 333 transmits the dynamic setting screen data to the requesting serviceman mobile terminal 230 (step S1101). Next, the maintainer 250 is waited for input, i.e., reception of the dynamic data 430 (step S1102).
Upon receiving the dynamic data 430 in which any of the dynamics (any of departure, return, entry, extension, and termination) other than leaving is set via the dynamic setting area 412 (step S1103), the dynamic management unit 333 ends the dynamic setting reception process.
On the other hand, when receiving the dynamic data 430 for which the leaving is set (step S1103), the dynamic management unit 333 checks whether or not there is a next job plan (step S1105). The determination is made with reference to the work schedule DB 342.
When the next job plan is present, the process is directly ended. On the other hand, when there is no next job plan, the dynamic state managing unit 333 transmits the return information input screen data to the maintainer moving terminal 230 (step S1106). Next, the maintenance worker 250 waits for an input (step S1107), calculates a return schedule time using the obtained return schedule information 438 (step S1108), and ends the processing.
The reasonableness check may be performed at the time of each dynamic setting in the dynamic setting reception process. The plausibility check performed here is a check in a setting order such as entering after the departure has to be set, leaving after the entering has to be set, and the like.
The motion management unit 333 stores motion history data of the maintenance worker 250 based on the motion data 430 generated by the above-described processing. When the leaving or the suspension is set in the dynamic state 433, the job schedule management unit 332 is notified.
Upon receiving the notification of the departure or suspension from the dynamic state managing unit 333, the operation plan managing unit 332 sets an end/suspension flag 516 for the operation plan specified by the maintainer ID432 and the field ID435 stored in the dynamic data 430.
[ maintainer status management processing ]
Next, the flow of the maintenance-person-state management process performed by the maintenance-person-state managing unit 334 will be described with reference to fig. 8. The maintainer state managing unit 334 generates or updates the maintainer state data 344 and manages the maintainer state each time the dynamic data 430 is received from the maintainer mobile terminal 230. The maintainer status data 344 is updated each time the maintainer 250 updates the dynamic. At this time, the dynamic data 430 and the job plan DB342 are used to generate the data.
The maintenance person status data 344 is generated or updated so that the maintenance person status management unit 334 keeps the security check time in the latest state. Here, the description will focus on updating the safety confirmation time.
First, when the dynamic data 430 having the departure dynamics 433 set therein is received (step S1301), the maintainer status data 344 having the maintainer ID432 in the dynamic data 430 in the maintainer specifying information 411 is generated, and the process is terminated.
At the time of generation, the maintainer state managing unit 334 registers the site specifying information 513 of the first registered work plan in the work plan DB342 for the next site name 546. And registers the safety confirmation time for confirming the arrival in the safety confirmation time information 515 of the job plan in the safety confirmation time 547 (step S1302).
In addition, the information of the maintainer identified by the maintainer ID432 in the dynamic data 430 is registered in the maintainer identification information 541. In the current state, the log-in indicates information between departure and arrival at the scene, such as movement, and the like. The position information 437 in the dynamic data 430 is registered in the position information 543.
When the maintenance person status data 344 is generated, no log is made in the security status 544, the current field name 545, the set extension number 548, and the automatic extension number 549.
On the other hand, when entry is set in the dynamic state 433 (step S1303), the serviceman status data 344 having the already generated serviceman ID432 in the serviceman specifying information 541 is extracted and updated, and the processing is terminated.
At the time of update, the current state 542 is updated to information indicating that it is in an entered state, for example, entered. The position information 543 is updated to the position information 437 of the motion data 430. The current field name 545 is registered with the field information determined by the field ID 435.
Referring to the work plan DB342, site specification information 513 of a record next to the record specified by the work plan ID434 is registered in the next site name 546. The completion check time of the recorded safety check time information 515 of the job schedule DB342 is registered in the safety check time 547 (step S1304).
Next, when leaving is set in the dynamic state 433 (step S1305), the serviceman status data 344 having the already generated serviceman ID432 in the serviceman specifying information 541 is extracted and updated, and the processing is terminated.
At the time of updating, first, it is determined whether or not the return schedule information 438 is stored in the dynamic data 430 (step S1306).
If not, the current status 542 is updated to information indicating that the vehicle is moving, the location information 543 is updated to the location information 437 of the dynamic data 430, the current field name 545 is deleted, the safety confirmation time 547 is updated, and the process is ended. At this time, the safety check timing 547 is set as the arrival check timing at which the site specifying information 513 in the work plan DB342 is the record of the next site name 546 (step S1307).
On the other hand, when the return schedule information 438 is stored, the current status 542 is updated to information indicating that the mobile terminal is moving, the location information 543 is updated to the location information 437 of the dynamic data 430, the current field name 545 and the next field name 546 are deleted, the safety check time 547 is updated, and the process is ended. At this time, the dynamic state managing unit 333 registers the return schedule time calculated from the return schedule information 438 in the security check time 547 (step S1308).
Next, when the extension is set in the dynamic state 433 (step S1309), the serviceman status data 344 having the already generated serviceman ID432 in the serviceman specification information 541 is extracted and updated, and the processing is terminated.
At the time of update, the security confirmation timing 547 is extended (step S1310), and 1 is added to the set extension count 548 (step S1311). In this case, safety confirmation time 547 is a value obtained by adding a predetermined extension time Δ Ts to the current value. Other items take the current status value.
When the return is set in the dynamic state 433 (step S1312), the contents of the maintainer status data 344 having the maintainer ID432 in the maintainer specifying information 541 are all cleared (step S1313), and the process ends.
When another value is set in the dynamic state 433, that is, when the suspension is set, no processing is performed and the process is terminated. This is because the status of the maintainer 250 has not changed.
In any case, when setting safety confirmation time 547, a value obtained by adding a predetermined margin value N to the time set in operation plan DB342 may be taken.
[ safety confirmation processing ]
Next, a flow of the security check process including the security check extension process performed by the security check unit 335 according to the present embodiment will be described. The safety check unit 335 of the present embodiment basically monitors the safety check time 547 of the serviceman status data 334. When the time comes and the information indicating the end of the inspection is not received, the security confirmation contact is made to the serviceman mobile terminal 230 held by the serviceman 250. However, the work is simply extended in many cases. Thus, in the present embodiment, the safety confirmation time is automatically extended up to 2 times.
First, the safety check unit 335 refers to the safety check time 547 of the serviceman status data 344 at predetermined time intervals, and determines whether the time has elapsed (step S1401).
When this time has elapsed, the safety check unit 335 first checks the number of times of automatic extension 549 of the serviceman status data 344, and determines whether or not the number of times of automatic extension has been twice (step S1402).
If the extension is not twice, the safety confirmation part 335 acquires the elevator state information (step S1403). Here, the elevator state information may be acquired by directly accessing the elevator control device 212 or may be acquired from the elevator state management section 312.
When the elevator state information is successfully acquired (step S1404), the safety checking unit 335 determines whether or not the elevator is under inspection using the acquired elevator state information (step S1405). Here, the determination is made based on whether or not the work switch 216 is turned on. When the switch is turned on, it is determined that the test is in progress.
When it is determined that the inspection is underway, the security confirmation unit 335 automatically extends the length (step S1406). Here, the security check time 547 in the maintainer status data 344 is newly registered by adding a predetermined extended period Δ Ts.
Next, the safety confirmation unit 335 determines a contact object to be contacted to notify that the safety confirmation time is extended (automatic extended contact). First, the number of times of extension up to now is checked with reference to the value of the automatic number of times of extension 549 (step S1407).
When the registered extension count is 0, that is, when extension is not performed, automatic extension contact is made to a predetermined administrator other than the serviceman 250 (step S1408). Here, as described above, the person is located in the monitoring center 301, the business hall 351, or the like. The contact is made by means of, for example, sending a template mail.
Then, the value of the auto-extension number 549 is incremented by 1 (step S1409), and the process returns to step S1401 to continue the time monitoring.
On the other hand, if the registration value of the auto-extension number 549 is not 0, that is, 1, it is first determined whether or not the work position of the serviceman 250 is a contactable spot (step S1410). The place which cannot be contacted in the inspection operation is, for example, on the car or in the shaft. In the present embodiment, the elevator state information is referred to, and the determination is made based on whether any of the switches is on. That is, if all the switches are off, the working position is determined to be a contactable point.
When it is determined that the contact point is a contactable point, the contact point is made with the administrator and the serviceman 250 (step S1411), and the process proceeds to step S1409.
On the other hand, when it is determined that the contact is not a contactable place, the process moves to step S1408, and only the administrator is contacted as in the first case.
When it is determined in step S1402 that the extension has been completed twice, when the elevator state information cannot be acquired in step S1404, and when the elevator is under inspection in step S1405, the manager or the maintainer 250 himself/herself is notified of the security confirmation (step S1413).
Next, it is determined whether or not there is another maintenance worker in the vicinity of the site (step S1414). The judgment is performed using the position information of the serviceman state data 344 of each serviceman. That is, it is determined whether or not the position information of the serviceman is within the area of the predetermined range centered on the position specified by the position information of the serviceman 250. The maintenance person in this area is referred to as a nearby maintenance person.
If there is a nearby maintenance worker, the nearby maintenance worker is also contacted (step S1415), the automatic extension number 549 is cleared (step S1416), and the process is ended. On the other hand, if there is no nearby maintenance person, the process proceeds to step S1416, and the process ends.
After that, when the security confirmation unit 335 does not respond to the security confirmation contact for a predetermined period, it may further output an alarm to an administrator or the like. Thus, the administrator can consider the countermeasure.
As described above, according to the present embodiment, the elevator monitoring system 100 includes: an elevator 210; a maintainer mobile terminal 230 carried by a maintainer 250 who checks the elevator 210; and a maintainer managing device 330 for managing the maintainer 250, wherein the maintainer mobile terminal 230 transmits the dynamic state set by the maintainer 250 to the maintainer managing device 330, and the maintainer managing device 330 includes: a maintainer state managing unit 334 configured to determine a security confirmation time based on the latest state of the maintainer 250 dynamically determined by the maintainer mobile terminal 230; and a security confirmation unit 335, wherein the security confirmation unit 335 performs security confirmation processing by the maintenance worker 250.
The safety confirmation unit 335 automatically extends the safety confirmation time when the safety confirmation time arrives and the serviceman 250 is still checking the elevator 210, and performs an automatic extension contact, which is a contact for extending the safety confirmation time, to the manager when the safety confirmation time is first and second extended, and also performs the automatic extension contact to the serviceman 250 when the serviceman 250 performs work at a contactable work location when the safety confirmation time is second extended.
As described above, according to the present embodiment, when the maintenance inspection work is extended, the safety check time is automatically extended. And, the extension is contacted to the administrator who manages the maintainer. Therefore, the administrator can reliably recognize that the security confirmation time is extended, and can appropriately perform security management.
In the second extension, the communication is also made to the maintenance worker 250 according to the work position of the maintenance worker 250. Therefore, when the serviceman 250 is located at a working position where the terminal operation is difficult, for example, a place other than on the car or in the shaft, the serviceman 250 is also notified with a prolonged communication. This enables the maintenance worker 250 to grasp the delay of the work progress of the worker. On the other hand, when the mobile terminal is located at a work position where the terminal is difficult to operate, the contact is not received. Therefore, the work is less obstructed.
If the inspection is not completed after the second extension, the security confirmation contact is made to the administrator and the maintenance worker at any work site. In addition, if there are other maintenance workers nearby, the other maintenance workers are also contacted. This makes it possible to confirm the safety of the maintenance worker more reliably.
As described above, according to the present embodiment, since the safety confirmation time is not continuously automatically extended, the safety of the serviceman 250 can be appropriately grasped.
Thus, according to the present embodiment, the safety of the maintenance worker can be appropriately managed without lowering the work efficiency.
The work position of the maintenance worker 250 is automatically determined based on the elevator state information transmitted from the elevator 210. Thus, the above-described effects can be obtained without adding a new structure.
The administrator may be notified when the extension is set by the maintainer 250 itself, that is, when the extension is set via the dynamic setting screen 410. For example, the maintenance person status management unit 334 receives the dynamic state data 430 in which the extension is set in the dynamic state 433, and notifies the security confirmation unit 335 of the received situation. Upon receiving the notification, the security confirmation unit 335 notifies the administrator that the extension is set by the serviceman 250.
With such a configuration, the administrator can reliably grasp extension of the work time, that is, extension of the safety confirmation time, in addition to automatic extension. The maintainer 250 does not need to contact himself. Therefore, the work of the maintenance worker 250 can be further prevented from being disturbed, and the safety of the maintenance worker can be appropriately managed.
