Next, limiting maintenance function the detailed of the maintenance function control process in processing unit 16 with reference to Fig. 3 and Fig. 4 Situation is illustrated.The maintenance function control process illustrated below is to have input maintenance fortune in group's management control activity reason of elevator Performed processing in the case of row instruction.Group's management control activity reason of elevator is identical with existing processing, so omitting in detail Explanation.
As shown in figure 3, first, maintenance function limitation processing unit 16 judges whether have maintenance operation to refer to by maintenance staff Order input (S1).Maintenance function limitation processing unit 16 monitors the maintenance operating instruction from maintenance operation identifying processing portion 15, In the case of having the input of maintenance operating instruction by maintenance staff, maintenance operation is exported from maintenance operation identifying processing portion 15 Instruction.For maintenance operating instruction input for, as described above shown in, pass through the mesh of elevator lobby destination floor input unit 1 Ground floor input unit 2 Password Operations (after " 0 " button that 3 numerical keys have been pressed within 2 seconds, the input password of 4) or Person reads the ID card informations of maintenance operating instruction, so as to be output.
Moreover, in step sl, being judged as in the case of have input maintenance operating instruction, maintenance function limitation processing unit 16 Period judging part 18 judge whether to relieve limitation item (S2).Here, so-called limitation item for example means maintenance fortune The period that row instruction is transfused to is the situation of commuter time section or the rush hours section.Period judging part 18 is transported in maintenance In the case that the period that row instruction is transfused to is commuter time section or the rush hours section, it is judged as the thing that do not lift restrictions , in the case where the period that maintenance operating instruction is transfused to is normal state or lonely state, it is judged as relieving limit Item processed.
In step s 2, in the case where being judged as that the period that have input maintenance operating instruction meets limitation item, i.e. It is commuter time section or the rush hours section, in the case that traffic flow is not normal state or lonely state, due to that can not enter Row maintenance operation login, thus maintenance function limitation processing unit 16 maintenance can not notification unit 21 will maintain additional notifications output Reporting unit 4 (S6) to elevator lobby destination floor input unit 1.
Generally, maintenance staff can predict or investigate the use form for the elevator being arranged in building, and be used as limitation thing The building that carry out maintaining operation is gone to outside the period of item.But, it is not as prediction in the traffic flow in building etc. In the case of so that without the login of maintenance operation in above-mentioned steps S2.Therefore, not the maintenance of override single elevator is transported OK, the utilization form of the lift appliance but in the meeting override building, can prevent from damaging user's because maintaining operation Convenience.
On the other hand, in step s 2, it is being judged as YES the normal state or lonely state that relieve limitation item In the case of, service terminates judging part 19 and judges the whether whole being serviceds (S3) of the calling of login of the single elevator.
In the case of being judged as that the service for having logged in calling all terminates in step s3, handled by maintaining operating instruction Maintenance operating instruction (S4) is given to the single elevator in portion 17.The floor for being transfused to maintenance operating instruction is moved to, reaching should Maintenance is switched to run during floor.In addition, now carrying out " * * by the reporting unit 4 of elevator lobby destination floor input unit 1 Elevator has switched to maintenance to run." as switching and booting report.In addition, as other Notification Methods, existing and using sound Export and above-mentioned guiding is shown on above-mentioned guiding or the display set in car or by making to be arranged on elevator lobby Signal lamp it is next from reaching the different flickering method of guiding (flicker etc. while the reservation lamp in upper direction, the reservation lamp in lower direction) Method notified etc..
On the other hand, it is judged as being not in the case of all servicing for having logged in calling in step s3, The maintenance allocation model processing of the single elevator is transferred to maintenance allocation model processing unit 20 in group's management control system 7 (S5)。
Next, with reference to Fig. 4 to the maintenance allocation model of the maintenance allocation model processing unit 20 carried out in step s 5 at The details of reason is illustrated.
The maintenance allocation model processing unit 20 of maintenance function limitation processing unit 16 judges whether to be transferred to maintenance distribution Single elevator (S6) in pattern.Be transferred in step s 6 maintenance allocation model in single elevator it is non-existent in the case of, Maintain allocation model processing unit 20 and terminate the processing.
On the other hand, in the case of there is the single elevator being transferred in maintenance allocation model in step s 6, maintenance point Judge whether to have input the new calling (S7) of the lift car of user with mode treatment portion 20.It is judged as not having in the step s 7 In the case of the new calling of input, the processing for continuing to be set to maintain allocation model by the single elevator and performing aftermentioned step S11.
On the other hand, it is judged as in the step s 7 in the case of have input new calling, maintenance allocation model processing unit 20 is sentenced Whether number is taken in the prediction of the disconnected single elevator full (S8).
On the other hand, be judged as in step s 8 the single elevator the prediction number of taking do not have it is full in the case of, sentence The disconnected floor that sets out, purpose floor and the directionality newly called whether the login with the single elevator as maintenance allocation model The stopping floor and directionality of calling are consistent (S9).
In the case of being judged as in step s 9 unanimously, new calling is distributed to the separate unit by maintenance allocation model processing unit 20 Elevator (S10).
On the other hand, be judged as in step s 8 the single elevator prediction take number it is full in the case of, Yi Ji Be judged as in step S9 it is inconsistent in the case of, maintenance allocation model processing unit 20 excludes the list for the new calling from distribution Platform elevator (S13).
In this way, by maintaining allocation model processing unit 20, from and the service that has logged in calling do not terminate all and shift Single elevator to maintenance allocation model has logged in calling and efficiently serviced for still remaining, makes to have logged in calling entirely Terminate in portion.But, in the case where all situations of service can not be completed, from the distribution of car call in maintenance allocation model Middle exclusion single elevator so that new calling is not allocated to the single elevator.
Then, maintenance function limitation processing unit 16 judges the whether whole being serviceds of the calling of login for the single elevator (S11).In the case of being judged as completing all services in step s 11, maintenance allocation model processing unit 20 is transported by maintaining Row instruction 17 pairs of single elevators of processing unit give maintenance operating instruction.
On the other hand, in the case of being judged as not completing all services in step s 11, allocation model processing unit is maintained 20 continue to be set to the single elevator to maintain allocation model.
Then, in step s 11, receive maintenance operating instruction the single elevator be moved to have input maintenance operation refer to The floor of order, and switch to maintenance to run when reaching the floor.In addition, now being inputted by elevator lobby destination floor The reporting unit 4 in portion 1 carries out that " switching of * * elevators is in order to maintain operation." as switching and booting report.In addition, being used as other Notification Method, exists and above-mentioned guiding is shown on the display for exporting above-mentioned guiding with sound or being set in car or logical Cross make the signal lamp for being arranged on elevator lobby from reach the different flickering method of guiding (upper direction preengage lamp, lower direction it is pre- About lamp while flicker etc.) come method for being notified etc..
