The present invention relates to an elevator system capable of automatically recovering an elevator when it is assumed that the elevator is hardly damaged even when an earthquake sensor detects a high acceleration.

In the elevator, earthquake control operation is performed when an earthquake occurs. In the case of earthquake control operation, for example, when the acceleration of the ground surface detected by the earthquake sensor exceeds a predetermined low threshold, it stops at the nearest floor and then performs automatic recovery diagnosis and automatically recovers, and when the acceleration exceeds a predetermined high threshold For example, stop driving after stopping on the nearest floor. When operation is stopped due to earthquake control operation, a professional engineer mobilizes to the elevator to perform human recovery (for example, refer to Patent Document 1).

<Operation of elevator system>

Next, the operation of the elevator system 100 when an earthquake occurs will be described with reference to FIGS. 2 to 6 . In the following description, as shown in Fig. 3, earthquake information 410 and 420 including seismic intensity information for each district in each prefecture, together with the epicenter and earthquake magnitude, is obtained from organization A and organization B, respectively. It is assumed that earthquake information 430 that is input to the information processing device 310 and includes the acceleration of the city or town of each prefecture from the organization C is input to the information processing device 310 .

As shown in step S101 of FIG. 5, the control panel 200 monitors the acceleration of the ground surface input from the earthquake sensor 220, and when the earthquake detection acceleration LL, for example, exceeds about 30 gal, an earthquake occurs. It is determined that it has occurred and the process proceeds to step S102 of FIG. 5 to determine whether the acceleration input from the seismic sensor 220 exceeds the operation stop value L. Here, the operation stop threshold value L is larger than the earthquake detection acceleration LL, and may be, for example, about 80 gal. If the acceleration does not exceed the operation stop value (L), it proceeds to step S103 of Figure 5, the control panel 200 stops the operation by stopping the car 22 of the elevator 20 to the nearest floor, After a predetermined time elapses, for example, after 3 minutes have elapsed, the normal operation of the elevator 20 is restarted. In addition, when the acceleration exceeds the operation stop threshold value L in step S102 of FIG. 5 , the process proceeds to step S104 of FIG. 5 , and the control panel 200 determines whether the acceleration exceeds the operation stop threshold value H to judge Here, the operation stop threshold value H is larger than the operation stop threshold value L, and may be, for example, about 120 gal. When the acceleration does not exceed the operation stop value H, the control panel 200 jumps to step S111 of FIG. 6 , resets the earthquake sensor 220, and executes an automatic recovery diagnosis operation. This will be explained later.

On the other hand, if the acceleration exceeds the operation stop threshold value H, the control panel 200 judges "Yes" in step S104 of FIG. 5 and proceeds to step S105 of FIG. 5, as shown in FIG. While stopping the operation of the elevator 20, the operation stop signal and the high acceleration detection signal are output. As shown in FIG. 2 , the operation stop signal and the high acceleration detection signal output by the control panel 200 are input to the communication device 210 . The communication device 210 transmits a driving stop signal and a high acceleration detection signal to the communication network 30 . The transmitted driving stop signal and high acceleration detection signal are received by the communication device 320 of the monitoring center 300 and are input to the information processing device 310 of the monitoring center 300 .

The information processing device 310 receives a stop operation signal and a high acceleration detection signal from the elevators 20 in each location. As shown in step S106 of FIG. 5 , the information processing device 310 generates the high acceleration detection elevator list 500 shown in FIG. 3 based on the received signal. The high acceleration detection elevator list 500 is a list of the identification number and installation location of the elevator 20 that transmits the high acceleration detection signal.

Next, as shown in Figs. 2 and 3, the information processing apparatus 310 generates the self-recovery diagnosis execution feasibility determination table 510 in step S107 of Fig. 5 . The information processing device 310 refers to the seismic intensity information and acceleration information for each district of each prefecture in the earthquake information 410 , 420 , 430 from the organization A, organization B, and organization C in the high acceleration detection elevator list 500 . Accordingly, the automatic recovery diagnosis execution possibility determination table 510 is generated as follows.

When the progress information from the tissue A of the earth including the installation place of the elevator 20 that has sensed high acceleration is less than the progress threshold, the information processing device 310, the elevator 20 in the high acceleration detection elevator list 500 ), enter “OK” in the earthquake information column of organization A. Conversely, if the seismic intensity information from the tissue A of the earth including the installation location of the elevator 20 that has sensed the high acceleration is greater than or equal to the seismic intensity threshold, the information processing device 310, the seismic information of the tissue A of the elevator 20 Enter "NG" in the field of The same is true for seismic information from organization B. Here, the seismic intensity threshold is a seismic intensity at which the elevator 20 is not damaged, and may be, for example, seismic intensity 5 or the like. In this case, the information processing device 310, in the elevator 20 with identification numbers S1001 and S1002 installed in Saitama prefecture with seismic intensity 3 or 4, organization A of the self-recovery diagnosis execution/failure determination table 510, Enter "OK" in the earthquake information column of B, and enter "NG" in the earthquake information column of organizations A and B in the elevator 20 with identification number C1001 installed in Chiba Prefecture, including seismic intensity 5 do.

In addition, when the acceleration information from the tissue C of the earth including the installation location of the elevator 20 that has sensed the high acceleration is less than the recoverable threshold, the information processing device 310 performs the automatic recovery diagnosis execution decision table 510 "OK" is inputted in the earthquake information column of the organization C of the elevator 20 in it. Conversely, when the acceleration information from the tissue C of the earth including the installation location of the elevator 20 that has sensed the high acceleration is greater than or equal to the recoverable threshold, the information processing device 310 performs the earthquake of the tissue C of the elevator 20 Enter "NG" in the information field. Here, the recoverable threshold is an acceleration that does not cause damage to the elevator 20 that is larger than the operation suspension threshold (H) 120 gal, and may be, for example, about 250 gal. In this case, the information processing device 310 inputs "OK" in the earthquake information column of the organization C of the automatic recovery diagnosis execution pass/fail judgment table 510 in the elevator 20 installed in Saitama Prefecture with an acceleration of less than 250 gal, In the elevator 20 installed in Chiba Prefecture with an acceleration of 250 gal or more, "NG" is input in the earthquake information column of organization C.

Then, in step S108 of FIG. 5 , the information processing device 310 selects the elevator 20 in which “OK” is inputted in the at least two earthquake information columns in the automatic recovery diagnosis execution pass/fail judgment table 510 Accordingly, an automatic recovery diagnosis command sending list 520 as shown in FIG. 4 is generated. For example, in the elevator 20 of identification numbers S1001 and S1002 installed in Saitama Prefecture, since there are three "OK" in the earthquake information column, in the automatic recovery diagnosis command transmission list 520, the automatic recovery diagnosis is performed. "Send" is input to transmit the command. In addition, in the elevator 20 of identification number C1001 installed in Chiba Prefecture, since there is no "OK" in the earthquake information column, in the automatic recovery diagnosis command sending list 520, the automatic recovery diagnosis command is not sent. NG" is entered.

Then, the information processing device 310 outputs an automatic recovery diagnostic command as shown in step S109 of FIG. 5 and FIG. 2 based on the automatic recovery diagnostic command sending list 520 .

In this way, the information processing device 310, the earthquake information of at least two pieces of the plurality of earthquake information 410, 420, 430 acquired from the organizations A, B, and C, is the seismic intensity of the earth in which the elevator 20 is installed. When the threshold is less than the threshold, or when the acceleration of the earth's surface is less than the recoverable threshold, a signal for executing an automatic recovery diagnostic operation is output to the elevator 20 .

The output of the information processing device 310 is transmitted from the communication device 320 to the communication network 30 as shown in FIG. 2, and is received in step S110 of FIG. 5 and the communication device 210 as shown in FIG. do. The communication device 210 outputs the received automatic recovery diagnosis command to the control panel 200 .

When the automatic recovery diagnosis command is input from the communication device 210, the control panel 200 resets the earthquake sensor 220 as shown in step S111 of FIG. After checking the presence or absence of a passenger in the car 22 as shown in FIG. 6 , an automatic recovery diagnosis operation is executed as shown in step S113 of FIG. In addition, the reset of the seismic sensor 220 in step S111 of FIG. 6 may be executed after confirming the presence or absence of a passenger in the car 22 in step S112 of FIG. 6 and determining that there is no passenger in the car 22 .

As shown in step S112 of FIG. 6 , the control panel 200 receives the output of, for example, the weight sensor of the car 22 , the camera in the car 22 , the human body sensor in the car 22 , and the elevator 20 ) to check whether there are passengers inside the car 22 . When there is a passenger in the car 22 , the control panel 200 skips the automatic recovery diagnosis operation, proceeds to step S115 of FIG. 6 , and outputs a determination result of “recovery impossible” in step S115 of FIG. 6 . Here, the passenger is checked just in case, but even when there is a passenger inside the car 22, the door open button is lit, and the door can be opened by pressing the door open button.

Then, in step S116 of FIG. 6 , the control panel 200 transmits the determination result of “recovery impossible” to the monitoring center 300 via the communication device 210, and then sets the elevator 20 to suspend operation. As shown in step S117 of FIG. 6 , the communication device 320 of the monitoring center 300 receives this determination result and outputs it to the information processing device 310 . The information processing apparatus 310 displays the result of this determination on the display 331 . Based on this display, the supervisor 334 determines that "recovery is not possible" in the recovery confirmation of step S118 in FIG. The dispatch of the technician 350 is instructed.

On the other hand, when the control panel 200 determines that there are no passengers in the car 22 in step S111 of FIG. 6 , the control panel 200 proceeds to step S112 of FIG. 6 to perform an automatic recovery diagnosis operation. The diagnostic content of the automatic recovery diagnostic operation is, for example, checking the presence or absence of an abnormality in the torque of the hoisting motor (motor) while driving, and confirmation of an abnormal sound while driving. The automatic recovery diagnostic operation is, for example, the following operation. First, the control panel 200 performs a slow speed running diagnosis in which the car 22 travels at a slow speed of, for example, about 1 m/min. If there is no abnormality in the low speed driving diagnosis, the stop driving diagnosis of each floor stopping at each floor is performed at a low speed faster than the slow speed. If there is no abnormality in each floor stop running diagnosis, the control panel 200 performs the constant speed running diagnosis in which the vehicle travels at the rated speed. When there is no abnormality in the constant speed driving diagnosis, the control panel 200 performs the door opening/closing diagnosis for opening and closing the doors 13 and 26 on each floor. If there is no abnormality in the door opening/closing diagnosis, the control panel 200 ends the automatic recovery diagnosis operation as there is no abnormality. Then, the control panel 200 proceeds to step S115 of FIG. 6 , and outputs a determination of “recovery success” in step S115 of FIG. 6 .

Then, in step S116 of FIG. 6 , the control panel 200 transmits the determination result of “recovery success” to the monitoring center 300 via the communication device 210, and then resumes the normal operation of the elevator 20. . As shown in step S117 of FIG. 6 , the communication device 320 of the monitoring center 300 receives the determination result and outputs it to the information processing device 310 . The information processing apparatus 310 displays the result of this determination on the display 331 . In step S118 of Fig. 6, the supervisor 334 confirms this display and determines that "recovery is successful", the automatic recovery of the elevator 20 is terminated.

In addition, if an abnormality occurs during the automatic recovery diagnostic operation, the process proceeds to step S120 of FIG. 6 , and the control panel 200 stops the automatic recovery diagnostic operation. Then, the flow advances to step S115 in Fig. 6, and a determination result of "unrecoverable" is output. Then, in step S116 of FIG. 6 , the control panel 200 through the communication device 210 outputs a determination result of “recovery impossible” to the monitoring center 300, and then stops the elevator 20 from operation. .

As described above, in the elevator system 100 of this embodiment, even when the earthquake sensor 220 senses a high acceleration, when it is assumed that the elevator 20 is hardly damaged, the elevator 20 automatically recovery may be possible. Thereby, many elevators 20 can be restored in a short time.

In the above description, the elevator 20 in which "OK" is inputted in the columns of at least two earthquake information in the automatic recovery diagnosis execution/failure determination table 510 is selected, and the automatic recovery diagnosis command transmission list as shown in FIG. It has been described that (520) is generated. However, it is not limited to this, and the seismic intensity threshold and recovery threshold are set to about 4, 200 gal, which is smaller than the 5, 250 gal, described above, By selecting the elevator 20 in which "OK" has been input, the automatic recovery diagnosis instruction transmission list 520 as shown in FIG. 4 may be generated.

<Other operations of the elevator system>

Next, another operation of the elevator system 100 of the present embodiment will be described with reference to FIGS. 7 to 10 . First, the same reference numerals are attached to the same portions as those described with reference to FIGS. 1 to 6, and descriptions thereof are omitted.

In summary, this operation is as follows. First, the information processing device 310 of the monitoring center 300 acquires earthquake information of an area in which a plurality of elevators 20 are installed from a plurality of earthquake information providing organizations after an earthquake occurs. And, when no seismic intensity above the seismic intensity threshold is observed in the area, and no acceleration above the recoverable threshold is observed in the area, the elevator that transmits a high acceleration detection signal and a stop operation signal to the monitoring center 300 A signal for executing an automatic recovery diagnosis operation is generated for all elevators 20 installed in the area among (20).

When an earthquake occurs, as shown in step S106 of FIG. 10 , the information processing device 310 generates a high acceleration detection elevator list 500 . In addition, when an earthquake occurs, seismic information 410, 420, and 430 are inputted to the information processing device 310 from the organizations A, B, and C, respectively, as shown in FIG. 8 . In step S201 of FIG. 10 , the information processing device 310 generates a regional automatic recovery diagnosis execution/non-permission determination table 515 as shown in FIG. 8 . The information processing device 310 determines, from the seismic intensity information of each district of the organization A, whether there is a district in which a seismic intensity exceeding the seismic intensity threshold of 5 is observed in a specific region, for example, Saitama Prefecture. As shown in Fig. 8, since no seismic intensity exceeding the seismic intensity threshold of seismic intensity 5 is observed in Saitama prefecture based on the seismic intensity information of organization A, Enter "OK" in the field of earthquake information of organization A. Similarly, when there is no district in Saitama where a seismic intensity exceeding 5 is observed from the seismic intensity information for each district of the organization B, the information processing device 310 returns "OK" to the seismic information field of the organization B in Saitama Prefecture. Enter Conversely, as in Chiba Prefecture, when a seismic intensity of 5 is observed in even one district, "NG" is inputted in the earthquake information field for organizations A and B in Chiba Prefecture.

Further, the information processing device 310 determines, from the acceleration information of the tissue C, whether or not an acceleration exceeding the recoverable threshold of 250 gal is observed in Saitama Prefecture. And, as shown in Fig. 8, if there are no observation points that exceed the recoverable threshold of 250 gal in Saitama, " Enter "OK". Conversely, as in Chiba Prefecture, when an acceleration exceeding 250 gal is observed in even one Earth, "NG" is input in the earthquake information column of Organization C of Chiba Prefecture.

As shown in step S202 of Figs. 7 and 10, the information processing device 310, based on the regional automatic recovery diagnosis execution pass/fail judgment table 515 of Fig. 8, performs the automatic recovery diagnosis execution by region list shown in Fig. 9. (530) is created. The regional automatic recovery diagnosis execution availability list 530 is, in the regional automatic recovery diagnostic execution failure judgment table 515 of FIG. ·Prefectures and prefectures are allowed to perform automatic recovery diagnosis, and provinces, provinces, prefectures and prefectures with only one earthquake information set to “OK” are not allowed to perform automatic recovery diagnosis. In other words, it is a list of whether or not to perform automatic recovery diagnosis by province, province, prefecture, and prefecture.

Next, the information processing device 310, as shown in step S108 of FIGS. 9 and 10, combines the regional automatic recovery diagnosis execution possibility list 530 and the high acceleration detection elevator list 500 to give an automatic recovery diagnosis command. A call list 540 is created. This list sends an automatic recovery diagnosis command to all elevators 20 in provinces, provinces, prefectures, and prefectures that have become executable in the regional automatic recovery diagnosis execution permission list 530, and a regional automatic recovery diagnostic execution permission list ( 530), to all elevators 20 in the provinces, provinces, prefectures, and prefectures, the automatic recovery diagnosis command is not transmitted.

In this way, the information processing device 310 monitors the high acceleration detection signal and the driving stop signal when no progress above the seismic intensity threshold is observed in a specific region and no acceleration greater than or equal to the recoverable threshold is observed in that region. Among the elevators 20 sent to the center 300, a signal for executing an automatic recovery diagnosis operation is generated for all elevators 20 installed in the area.

The output of the information processing device 310 is transmitted from the communication device 320 to the communication network 30 as shown in steps S109 of Figs. 7 and 10, and is shown in steps S109 and 7 of Figs. It is received by the communication device 210 as shown. The communication device 210 outputs the received automatic recovery diagnosis command to the control panel 200 .

First, as in the operation described with reference to FIGS. 1 to 6 , when an automatic recovery diagnostic command is input from the communication device 210 , the control panel 200 executes an automatic recovery diagnostic operation as shown in step S113 of FIG. 6 .

As described above, this operation determines whether or not to perform the automatic recovery diagnostic operation for each specific region such as a province, a province, a prefecture, etc., not for each elevator 20, so that a large number of elevators ( 20) can be processed in a short time, and a large number of elevators 20, which are supposed to be hardly damaged in the event of an earthquake, can be restored in a short time.

In the above embodiment, each province, province, prefecture, and prefecture were described as one specific area. However, it is not limited to this, For example, Chiyoda-ku of Tokyo, Shinjuku-ku, etc. It is also possible to collectively determine whether or not to perform the automatic recovery diagnostic operation for each region by making the district as one specific region.
