By the way, when the P wave sensor operates during an earthquake, the elevator automatically stops on the nearest floor, opens the door, drops passengers, and then performs automatic diagnostic operation. If there are no abnormalities, the elevator automatically recovers and resumes operation. In many cases, the elevator does not stop operating. However, when the acceleration of the ground surface due to the S wave coming after the P wave is high, the operation is temporarily suspended for safety and restarted after the inspection by the technician. Therefore, when the acceleration of the ground surface due to the S wave is high, it is necessary to inspect the elevator by a technician.

For this reason, when high acceleration on the ground surface is detected in many elevators, it is necessary for engineers to efficiently patrol and inspect many elevators and restart the operation of the elevators in a short time.

However, if high acceleration on the ground surface is detected, the building where the elevator is installed may be damaged and the elevator may not be inspected, or even if the elevator is inspected, operation may not be resumed. .. In addition, transportation infrastructure such as roads and bridges to buildings may be damaged, and it may not be possible to reach the building where the elevator is installed.

In this case, the technician who inspects and restores the elevator may not know which building is damaged, what kind of transportation infrastructure is damaged, and which building's elevator should be inspected. .. For this reason, it may be difficult to efficiently restart the operation of the elevator due to waste of travel time between buildings.

Therefore, an object of the present invention is to support an engineer who performs restoration work of an elevator when a high acceleration of the ground surface is detected due to an earthquake, and to efficiently restart the operation of the elevator.

The elevator system of the present invention includes an elevator provided with an earthquake detector that detects acceleration on the ground surface, an information center that is connected to the elevator to monitor the elevator, and an information center that is connected to the information center and is connected to the elevator when an earthquake occurs. An elevator system that includes a business establishment where a technician who performs restoration work works, and an unmanned vehicle equipped with a camera that is capable of autonomous flight and is deployed at the business establishment. The elevator is equipped with the earthquake detector. When a high acceleration or high seismic intensity exceeding the operation suspension threshold is detected, the operation is suspended and a high acceleration detection signal and an operation suspension signal are transmitted. When the operation suspension signal is received, the unmanned vehicle is made to fly toward the building where the elevator that transmits the high acceleration detection signal and the operation suspension signal in the area under the jurisdiction of the business establishment is installed. , The unmanned air vehicle transmits a damage situation image of the damage situation of the building and the damage situation of the traffic infrastructure in the district to the information center, and the information center receives the damage from the unmanned air vehicle. Based on the situation image, the damage situation of the building and the transportation infrastructure in the district is determined, and the primary response building for dispatching the engineer is extracted from the building, and the office and the mobile terminal of the engineer are used. It is characterized by transmitting to either one or both of the above.

In this way, when a high acceleration on the ground surface is detected due to an earthquake, the information center extracts the primary response building that dispatches the technician based on the damage situation image received from the unmanned aircraft, and the office or technician. Since it is sent to the mobile terminal of the technician, the technician can patrol only the buildings that can be used for the primary response. As a result, it is possible to assist the technician and efficiently restart the operation of the elevator.

In the elevator system of the present invention, the information center compares the disaster situation image received from the unmanned vehicle with the normal image of the building and the district in normal times, and the traffic in the building and the district. You may judge the damage situation of the infrastructure.

In this way, since the damage situation of the building and the transportation infrastructure is judged by comparing the damage situation image and the normal time image, the damage situation can be judged in a short time by a simple method.

In the elevator system of the present invention, the elevator transmits a confinement generation signal to the information center when confinement occurs when the operation is stopped, and the information center confinees from the extracted primary corresponding building. The building in which the elevator is installed may be extracted as a priority primary response building and transmitted to either or both of the business establishment and the mobile terminal of the engineer.

As a result, the technician can preferentially patrol the building where the elevator where the confinement has occurred and efficiently eliminate the confinement.

In the elevator system of the present invention, the information center provides a movement route from the primary response building or the priority primary response building to another primary response building or another priority primary response building from road traffic information and railway operation information. It may be set and transmitted to either or both of the business establishment and the mobile terminal of the technician.

In this way, the information center sets the movement route from one building to another and sends it to the office or the technician, so that the technician efficiently patrols the building where the elevator that needs inspection is installed. be able to.

In the elevator system of the present invention, when there are a plurality of the primary response building and the priority primary response building, the information center prioritizes the primary response based on the use of each building, and based on the priority. Set the movement route from the primary correspondence building or the priority primary correspondence building to the other primary correspondence building or the other priority primary correspondence building, and either one of the business establishment and the mobile terminal of the technician or You may send to both.

This makes it possible to efficiently patrol many buildings, efficiently open the confinement, and restore the elevator.

The present invention can efficiently restart the operation of the elevator by assisting the technician who performs the restoration work of the elevator when a high acceleration of the ground surface is detected due to an earthquake.

Next, the operation of the elevator system 100 will be described with reference to FIGS. 2 to 8. In the following explanation, as shown in FIG. 2, as an example, in the district 70 under the jurisdiction of the business establishment 50, there are eight buildings from A building 71 to H building 78, and an elevator 20 is installed in each building. Explain that it is. Here, A building 71 and G building 77 are buildings containing commercial facilities, B building 72 and H building 78 are office buildings, and C building 73 is a building of a public institution such as a government office. The D building 74 and the E building 75 are middle-rise condominiums. F Building 76 is a hospital. Elevators 20 similar to those described above with reference to FIG. 1 are installed in each of the buildings 71 to 78, and each elevator 20 is connected to the information center 30 via a communication line 29. For A building 71 to G building 77, the illustration of the connection state is omitted.

As shown in step S101 of FIG. 5, the elevators 20 installed in each building 71 to 78 stand by until the P wave sensor 27p in the seismic detector 27 of the seismic control device 26 operates. Then, when the P wave sensor 27p is activated, the seismic control device 26 proceeds to step S102 in FIG. 5 to transmit a P wave detection signal to the control device 25. When the P wave detection signal is input, the control device 25 stops the car 21 of the elevator 20 on the nearest floor and opens the door so that the passengers get off the elevator 20 as shown in step S103 of FIG. Announce.

As shown in step S104 of FIG. 5, the seismic control device 26 stands by until the S wave sensor 27s operates. Then, when the S wave sensor 27s operates, the process proceeds to step S105 in FIG. 5, and it is determined whether or not the S wave sensor 27s has detected a high acceleration exceeding the operation suspension threshold value. If the seismic control device 26 determines YES in step S105 of FIG. 5, the seismic control device 26 proceeds to step S106 of FIG. 5 and outputs a high acceleration detection signal and an operation suspension signal to the control device 25. When the high acceleration detection signal and the operation suspension signal are input, the control device 25 outputs the high acceleration detection signal and the operation suspension signal to the monitoring device 28. As shown in FIG. 2, the monitoring device 28 transmits a high acceleration detection signal and an operation suspension signal to the information center 30 via the communication line 29. Further, the control device 25 suspends the operation of the elevator 20 in step S107 of FIG.

Further, the control device 25 determines in step S108 of FIG. 5 whether or not the car 21 is stopped between the landing floors and the passengers are trapped in the car 21. Then, if the control device 25 determines YES in step S108 of FIG. 5, the control device 25 proceeds to step S109 of FIG. 5 and outputs a confinement generation signal to the monitoring device 28. As shown in FIG. 2, the monitoring device 28 transmits the confinement generation signal input via the communication line 29 to the information center 30.

If the seismic control device 26 determines NO in step S105 of FIG. 5, it proceeds to step S110 of FIG. 5 and outputs a low acceleration detection signal to the control device 25. The control device 25 outputs the input low acceleration detection signal to the monitoring device 28. The monitoring device 28 transmits a low acceleration detection signal to the information center 30 via the communication line 29.

When the monitoring device 28 receives the automatic diagnosis operation command from the information center 30 in step S111 of FIG. 5, the control device 25 causes the control device 25 to execute the automatic diagnosis operation, and the result is transmitted to the information center 30. Further, when the monitoring device 28 receives the automatic recovery command from the information center 30 in step S112 of FIG. 5, the monitoring device 28 outputs the automatic recovery command to the control device 25 to automatically recover the elevator 20.

In the following explanation, the elevator 20 installed in the E building 75 does not detect the high acceleration exceeding the operation suspension threshold, but transmits the low acceleration detection signal to the information center 30, and the other A building 71 to D building 74. , Each elevator 20 installed in the F building 76 to the H building 78 detects a high acceleration exceeding the operation suspension threshold, and transmits the high acceleration detection signal and the operation suspension signal to the information center 30.

As shown in step S201 of FIG. 6, the server 31 of the information center 30 waits until the high acceleration detection signal and the operation suspension signal are received from the monitoring device 28 of each elevator 20 installed in each building 71 to 78. ing. Then, when the server 31 receives the high acceleration detection signal and the operation suspension signal from the elevators 20 installed in the A building 71 to the D building 74 and the F building 76 to the H building 78, in step S201 of FIG. If YES, the process proceeds to step S202 of FIG. Then, in step S202 of FIG. 6, the server 31 transmits the high acceleration detection signal and the operation suspension signal received via the in-house line 59 to the business establishment 50 as shown in FIG. Further, when the server 31 of the information center 30 receives the confinement generation signal from the monitoring device 28 of the elevator 20, the confinement generation signal is transmitted to the business establishment 50 in step S202 of FIG.

As shown in step S301 of FIG. 7, the terminal 51 of the business establishment 50 waits until the high acceleration detection signal and the operation suspension signal are received from the information center 30. Then, if the terminal 51 determines YES in step S301 of FIG. 7, the terminal 51 proceeds to step S302 of FIG. 7, and the elevator 20 that transmits the high acceleration detection signal and the operation suspension signal of the district 70 under its jurisdiction is installed. The position information of the building 71 to D building 74 and the F building 76 to H building 78 is output to the drone operation device 52.

The drone operating device 52 sets the flight route 79 based on the position information between the A building 71 to the D building 74 and the F building 76 to the H building 78 input in step S302 of FIG. Then, the drone operating device 52 transmits the drone 60 as shown in step S303 and FIG. 2 of FIG.

As shown in FIG. 3, the drone 60 flies around the A building 71 to the D building 74 and the F building 76 to the H building 78 along the set flight route 79, and becomes the A building 71 to the D building 74. , The damage situation of F building 76 to H building 78 and the damage situation of the transportation infrastructure in the district 70 are photographed and transmitted to the information center 30 as a damage situation image. The disaster situation image may be a moving image or a still image. At this time, the drone 60 does not fly around the E building 75 to which the high acceleration detection signal and the operation suspension signal are not transmitted from the elevator 20.

As shown in step S203 of FIG. 6, the communication unit 32 of the server 31 of the information center 30 receives the damage situation image transmitted by the drone 60 and stores it in the damage situation image database 48.

In step S204 of FIG. 6, the disaster status determination unit 41 of the server 31 refers to the elevator attribute database 45, the map database 46, the normal image database 47, and the disaster status image database 48, and refers to the buildings A 71 to D. The damage status of the building 74 and the F building 76 to the H building 78 and the damage status of the transportation infrastructure in the district 70 are determined.

The disaster situation determination unit 41 reads out the normal image including the image of the A building 71 in normal time and the image of the traffic infrastructure around it from the normal image database 47. Further, the disaster situation determination unit 41 reads out the disaster situation image including the image of the damage situation of the A building 71 after the earthquake and the image of the damage situation of the transportation infrastructure around the disaster situation image database 48. Then, the disaster status determination unit 41 determines the damage status of the transportation infrastructure in and around the A building 71 by comparing the normal image and the disaster status image.

Similarly, the disaster situation determination unit 41 compares the normal image of the B building 72 to D building 74, the F building 76 to H building 78 and its surroundings with the disaster situation image, and sets the B building 72 to D building 74. , The damage situation of F building 76 to H building 78, and the damage situation of the transportation infrastructure around it are determined.

As shown in FIG. 2, the damage situation determination unit 41 cannot reach the B building 72 because the surrounding roads cannot pass through the B building 72, the D building 74 is in a half-destroyed state, and the other A building 71 and C building 73. , F building 76 to H building 78 are judged not to be damaged. Then, the disaster situation determination unit 41 outputs the determination result to the primary corresponding building extraction unit 42.

In step S205 of FIG. 6, the primary correspondence building extraction unit 42 extracts the primary correspondence building for which the engineers 53 and 54 are heading for the primary correspondence. The primary response building extraction unit 42 was determined to be non-damaged, excluding the D building 74, which was determined to be damaged by the damage status determination unit 41, and the B building 72, which was determined to be unreachable due to the damage to the transportation infrastructure. Extracted as A building 71, C building 73, F building 76 to H building 78 primary correspondence building. Then, the primary correspondence building extraction unit 42 outputs the primary correspondence building information to the priority primary correspondence building extraction unit 43, the movement route setting unit 44, and the communication unit 32.

The priority primary response building extraction unit 43 is confined from each elevator 20 installed in the A building 71, the C building 73, and the F building 76 to the H building 78 extracted as the primary response building in step S206 of FIG. Determine if a signal is being transmitted. If the priority primary correspondence building extraction unit 43 determines YES in step S205 of FIG. 6, the priority primary correspondence building extraction unit 43 extracts the building as the priority primary correspondence building in step S207 of FIG. As shown in FIG. 3, since confinement has occurred in the C building 73 and the H building 78, the priority primary corresponding building extraction unit 43 extracts the C building 73 and the H building 78 as the priority primary corresponding building. Then, the priority primary correspondence building extraction unit 43 outputs the priority primary correspondence building information to the movement route setting unit 44 and the communication unit 32.

In step S208 of FIG. 6, the movement route setting unit 44 acquires the input primary correspondence building information, priority primary correspondence building information, and road traffic information center 65 while referring to the elevator attribute database 45 and the map database 46. From the road traffic information of the district 70 and the railway operation information of the district 70 acquired from the railway operation information center 66, the movement route from the primary response building or the priority primary response building to another primary response building or another priority primary response building. To set.

At this time, when there are a plurality of primary correspondence buildings and priority primary correspondence buildings, the movement route setting unit 44 assigns a priority of primary correspondence based on the use of each building 10 and sets a movement route based on the priority. You may.

In addition, if there are multiple primary response buildings with the same priority and there are multiple priority primary response buildings with the same priority, the travel time between each building is calculated and the travel time is minimized. You may set a route.

In the following example, it is explained that two engineers 53 and 54 are working at the business establishment 50, and the two engineers are heading for the restoration of the elevator 20 by different routes. In this case, the movement route setting unit 44 sets two movement routes, a first route and a second route.

As explained earlier, since there are two priority primary response buildings in the district 70, the movement route setting unit 44, together with the first route and the second route, first heads for the priority primary response building, and then the primary response. Set a route to go around the corresponding building and return to the office 50. The priority for visiting the primary building is set in the order of hospital, public institution, commercial facility, office building, and housing. In addition, the order of going around the primary correspondence building may be made to go around sequentially from the vicinity of the priority primary correspondence building, or a route with the shortest travel time may be set by a combination of these.

As shown in FIG. 4, the movement route setting unit 44 first goes to the C building 73, which is the priority primary correspondence building, and then goes to the A building 71, which is the nearby primary correspondence building, and returns to the office 50. Set as the first route. In addition, the movement route setting unit 44 first goes to the H building 78, which is the priority primary response building, then to the F building 76, which has the highest priority hospital among the primary response buildings, and then to the commercial facility. The route that goes around the G building 77 and returns to the office 50 is set as the second route. Then, the set movement route information is output to the communication unit 32.

The communication unit 32 transmits the input primary correspondence building information, priority primary correspondence building information, and movement route information to the business establishment 50 and the mobile terminals 55 of the engineers 53 and 54 in step S209 of FIG. do.

In step S304 of FIG. 7, the terminal 51 of the business establishment 50 displays the primary correspondence building information, the priority primary correspondence building information, and the movement route information from the information center 30 on the display of the terminal 51.

In step S305 of FIG. 7, the business establishment 50 heads to the site on the first route and the second route based on the primary response building information input from the information center 30, the priority primary response building information, and the movement route information. Select engineers 53 and 54 and dispatch engineers 53 and 54 to the site.

The engineer 53 first heads for the C building 73, then goes around the A building 71 and returns to the office 50 according to the first route. Further, the technician 54 first heads for the H building 78 according to the second route, then goes around the F building 76 and the G building 77 and returns to the office 50. Further, the engineers 53 and 54 may go around the priority primary corresponding building and the primary corresponding building while receiving the information from the information center 30 by the mobile terminal 55.

As shown in FIG. 8, the engineers 53 and 54 arriving at the elevators 20 installed in the A building 71, the C building 73, and the F building 76 to the H building 78 are as shown in step S401 of FIG. If it is determined whether the building is a priority primary corresponding building and YES is determined in step S401 of FIG. 8, the process proceeds to step S402 of FIG. 8 to release the confinement. For the confinement opening, for example, the door may be opened from the outside of the car 21 of the elevator 20 with a key, and the passengers may be unloaded from the car 21 to unload the passengers. If there is a large step between the floor of the car 21 and the floor of the landing floor, release the brake and move the car 21 up and down to eliminate the step, then open the door with the key and passengers. May be removed from the basket 21.

After completing the confinement release, the engineers 53 and 54 proceed to step S403 in FIG. 8 to inspect each part of the elevator 20 and determine whether the elevator 20 can be restored. Then, if the engineers 53 and 54 determine YES in step S403 of FIG. 8, they reset the control device 25 and the earthquake detector 27 as shown in steps S404 and S405 of FIG. As a result, the restoration work of the elevator 20 is completed as shown in step S406 of FIG. The restoration work time of the engineers 53 and 54 in each elevator 20 is about 30 to 40 minutes. When the restoration work is completed, the engineers 53 and 54 perform completion registration from the mobile terminal 55 to the information center 30 and move to the next building 10.

Further, when the engineers 53 and 54 determine that the rope 23 needs to be replaced and cannot be restored only by resetting the control device 25 and the earthquake detector 27, they determine NO in step S403 of FIG. , The restoration work is completed without resetting the control device 25 and the earthquake detector 27, and the user moves to the next building 10.

The information center 30 transmits an automatic diagnosis operation command signal and an automatic recovery command signal to the elevator 20 installed in the E building 75 that has transmitted the low acceleration detection signal to the information center 30. Based on this command, the elevator 20 performs automatic diagnosis operation and automatic recovery as shown in steps S111 and S112 of FIG.

As described above, in the elevator system 100 of the embodiment, when a high acceleration exceeding the operation suspension threshold value is detected due to an earthquake, the engineers 53, 54 are based on the damage situation image received from the drone 60 by the information center 30. The primary response building to be dispatched is extracted and transmitted to the business establishment 50 or the mobile terminal 55 of the engineers 53 and 54. As a result, the engineers 53 and 54 patrol only the buildings 10 capable of primary response, and do not need to patrol the damaged buildings 10 and the unreachable buildings 10, reducing the loss of travel time and efficiently. The operation of the elevator 20 can be restarted.

Further, in the elevator system 100 of the embodiment, the damage status of the traffic infrastructure of the building 10 and the district 70 is determined by comparing the damage status image received from the drone 60 with the normal image of the building 10 and the district 70 in normal times. Therefore, it is possible to determine the damage situation in a short time by a simple method.

Further, in the elevator system 100 of the embodiment, the building 10 in which the elevator 20 in which the confinement has occurred is extracted as the priority primary response building, and the engineers 53 and 54 are preferentially dispatched, so that the time is short. It is possible to open the confinement.

Further, in the elevator system 100 of the embodiment, the information center 30 sets a movement route from the building 10 to another building 10 and transmits it to the business establishment 50 and the engineers 53, 54 to support the engineers 53, 54. Therefore, the engineers 53 and 54 can efficiently patrol the building 10 in which the elevator 20 that needs to be inspected is installed.

In the embodiment described above, it has been described that two engineers 53 and 54 perform the restoration work of each elevator 20, but one engineer 53 may perform the restoration work of each elevator 20.

At that time, the movement route setting unit 44 first goes to the C building 73, which is a high-priority public institution, for the C building 73, which has a public institution, which is a priority primary response building, and the H building 78, which is an office building. Next, the route is set so as to go to the H building 78, which is an office building. Then, for the A building 71 with the commercial facility, the F building 76 with the hospital, and the G building 77 with the commercial facility, the route is set so as to go to the F building 76 with the high priority hospital first. Then, for the A building 71 and the G building 77, which have the same commercial facilities in the same priority, the route is set so as to go to the G building 77, which has a short travel distance from the F building 76, and then to the A building 71.

This makes it possible to efficiently patrol many buildings 10 and efficiently open the confinement and restore the elevator 20.

Further, the seismic control device 26 of the elevator 20 described above includes an earthquake detector 27 that detects the acceleration of the ground surface, and suspends the operation when the seismic detector 27 detects a high acceleration exceeding the operation suspension threshold. Although it has been described that the elevator 20 transmits a high acceleration detection signal and an operation suspension signal, the present invention is not limited to this. For example, using a seismic intensity meter that converts the acceleration detected by the earthquake detector 27 into seismic intensity and outputs it, when the seismic detector 27 detects a high seismic intensity exceeding the operation suspension threshold, the operation is suspended and a high acceleration detection signal is used. The operation suspension signal may be transmitted.
