Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an elevator disaster prevention system that predicts inundation of a customer building due to torrential rain or the like in advance, and controls the operation of an elevator installed in the customer building accordingly.
[0002]
[Prior art]
For elevators installed in buildings, waterproofing work is performed on the hoistway, and drainage facilities are installed in the pits under the hoistway, and measures are taken to prevent the hoistway from being flooded during rainy weather. It is common. However, when a natural disaster such as a flood due to a torrential rain occurs, there is a concern that a large amount of water flows into the hoistway and the car is flooded, which may cause damage to equipment and the like. Therefore, in the event of a torrential downpour, a maintenance worker goes to a customer building where flood damage is expected to occur, stops the car on the top floor, and stops the operation.
[0003]
However, if a maintenance worker goes to a customer building and performs the above-mentioned measures in the event of a disaster, not only is the burden on the maintenance worker large, but also the maintenance worker will be in all customer buildings where flooding is predicted to occur. Is difficult to visit in a short period of time, and may not be able to accommodate all customer buildings.
[0004]
In view of such a point, when the monitoring center that monitors the elevators of a plurality of customer buildings collectively receives notification that any of the customer buildings is inundated, the elevator control of all the customer buildings is controlled. A technology has been proposed in which an evacuation signal is transmitted to a device using a telephone line, and the elevator control device of each customer building receives the evacuation signal to evacuate the car to a predetermined position (for example, Patent Document 1). reference.).
[0005]
According to the technology proposed in Patent Document 1, it is possible to prevent flooding of cars in elevators of all customer buildings without a maintenance worker going to customer buildings.
[0006]

JP-A-8-157160
[Problems to be solved by the invention]
By the way, the degree of inundation damage that each customer building suffers due to torrential rain, etc. is greatly affected by the location conditions of each customer building.For example, in a customer building built near a river, flood damage may reach the upper floors. On the other hand, it is assumed that a customer building built at a relatively high position will not be damaged by inundation. In addition, the degree of inundation damage that each customer building suffers also varies depending on the difference in rainfall for each region.
[0008]
However, in the technique proposed in Patent Document 1 described above, since the monitoring center transmits the same evacuation signal uniformly to all customer buildings, flood monitoring of each customer building is not necessarily required. However, there is a problem that appropriate measures cannot be taken according to the degree of the problem.
[0009]
The present invention has been made in view of the conventional circumstances as described above, and it is possible to accurately predict a customer building to which flood damage will occur and the degree of the damage, and to take appropriate measures according to the prediction. The purpose is to provide an elevator disaster prevention system that can be used.
[0010]
[Means for Solving the Problems]
In the elevator disaster prevention system according to the present invention, a monitoring center that collectively monitors elevators installed in a plurality of customer buildings is connected to an information providing server that provides disaster prediction information via a communication network, The monitoring center is a map data storage unit that stores customer location map data representing the location of each customer building on a three-dimensional map, and information about each customer building, which indicates at least the height position of each floor. Based on customer information storage means for storing customer information including information, disaster prediction information provided from the information providing server, and customer location map data stored in the map data storage means, Damaged building identifying means for identifying a predicted customer building; and customer information relating to the customer building identified by the damaged building identifying means, Means for reading out from the means, based on the customer information and the disaster prediction information provided from the information providing server, including a flooded floor specifying means for specifying a floor of the customer building corresponding to the flooded height. Features.
[0011]
In this elevator disaster prevention system, in the monitoring center, a customer building which is predicted to be affected by flooding among the customer buildings is specified by the damaged building specifying means, and corresponds to the degree of flooding of the customer building, that is, the flooding height. The floor of the customer building is specified by the flooded floor specifying means. Therefore, based on this information, it is possible to appropriately control the operation of the elevator installed in the customer building that is predicted to be affected by the flooding according to the degree of the flooding damage of the customer building.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0013]
(1st Embodiment)
The elevator disaster prevention system of the present embodiment transmits information from a monitoring center to a terminal of a sales office when it is predicted that flood damage will occur in a customer building, and urges a maintenance worker to take appropriate measures. As shown in FIG. 1, a monitoring center 1 and a sales office terminal 2 are connected via a communication network 3. An information providing server 4 for providing disaster prediction information is connected to the monitoring center 1 via a communication network 3.
[0014]
The monitoring center 1 collectively monitors elevators installed in a plurality of customer buildings, and includes a customer location map database 11, a customer information database 12, a damaged building identification processing unit 13, and a flooded floor identification processing. The information processing apparatus includes a unit 14, a flood damage information creation processing unit 15, and a display processing unit 16.
[0015]
The customer location map database 11 stores customer location map data. The customer location map data represents the location of each customer building monitored by the monitoring center 1 on a three-dimensional map. That is, in recent years, using a position measurement system such as a GPS (Global Positioning System), three-dimensional map data can be obtained by not only confirming the topography of a specific area on the ground and the location of a building, but also determining the altitude of the topography. The technology to create is established. The customer location map data represents the location of each customer building on the three-dimensional map data created in this way. Therefore, by referring to the customer location map data, the location conditions and the like of each customer building can be confirmed.
[0016]
The customer information database 12 stores customer information regarding each customer building. The customer information includes information indicating the specifications of each customer building such as the number of floors of each customer building and the height position of each floor, and management information such as a management number of an elevator installed in each customer building. These pieces of information are stored in the customer information database 12 in association with the identification numbers of the customer buildings.
[0017]
The damaged building identification processing unit 13 performs centralized processing based on the disaster prediction information transmitted from the information providing server 4 to the monitoring center 1 via the communication network 3 and the customer location map data stored in the customer location map database 11. It identifies customer buildings that are expected to be affected by flooding in the event of a disaster such as a flood due to heavy rain.
[0018]
The disaster prediction information transmitted from the information providing server 4 predicts, for example, precipitation, floods, tsunamis, and the like for each region. Each time such a disaster is predicted, information is provided. The data is transmitted from the server 4 to the monitoring center 1. When such disaster prediction information is transmitted from the information providing server 4, the damaged building identification processing unit 13 compares the disaster prediction information with the customer location map data stored in the customer location map database 11, and determines whether the flood damage has occurred. Identify potential customer buildings. Specifically, the damaged building identification processing unit 13 three-dimensionally analyzes the topography of each area where the monitored customer building is installed, based on the customer location map data, and transmits the analysis as disaster prediction information. Based on the information on precipitation, floods, tsunamis, and other occurrences in this area, the location and height of inundation are predicted. If the location of the customer building coincides with the location of occurrence of inundation, the customer building is specified as a customer building to which flood damage has occurred.
[0019]
The flooded floor identification processing unit 14 reads out customer information on the customer building identified as being affected by the flooding by the damaged building identification processing unit 13 from the customer information database 12 and compares the customer information with the disaster prediction information. Then, the floor of the customer building corresponding to the flood height, that is, the number of floors in the customer building specified to be affected by the flood is specified. Specifically, the flooded floor identification processing unit 14 confirms, for example, the height position of each floor of the customer building from the customer information of the customer building specified to be affected by the flooding. Then, the height position of each floor of the customer building is compared with the flood height predicted at the location of the customer building, and the floor of the customer building corresponding to the flood height is specified.
[0020]
The inundation damage information creation processing unit 15 identifies the customer building that is predicted to be affected by the inundation damage by the damaged building identification processing unit 13, and the inundation floor identification processing unit 14 determines the floor of the customer building corresponding to the inundation height. When the floor is specified, the detailed information is added to general disaster prediction information to create flood damage information. The flood damage information created by the flood damage information creation processing unit 15 is supplied to the display processing unit 16 and transmitted to the business office terminal 2 via the communication network 3.
[0021]
The display processing unit 16 performs a process of displaying various information on a display. In particular, when the flood damage information is supplied from the flood damage information creation processing unit 15, a general process is performed based on the flood damage information. Disaster prediction information and its detailed information are displayed on the display.
[0022]
FIGS. 2 and 3 show examples of display screens displayed on the display by the display processing unit 16. In a normal time when no disaster occurs, the disaster prediction information is not transmitted from the information providing server 4 to the monitoring center 1, and the flood damage information is supplied from the flood damage information creation processing unit 15 to the display processing unit 16. Since there is no such information, the display processing unit 16 appropriately displays the current date and time, information indicating that no disaster has occurred, and the like on a display screen as shown in FIG. 2 as appropriate. On the other hand, when disaster prediction information is transmitted from the information providing server 4 to the monitoring center 1 when a disaster such as a torrential downpour occurs, and the flood damage information is supplied from the flood damage information creation processing unit 15 to the display processing unit 16, the display processing unit Reference numeral 16 first displays general disaster prediction information on a display screen as shown in FIG. 3A based on the flood damage information. Then, when an operation for prompting a detail display is performed by a supervisor or the like who is stationed at the monitoring center 1, the name of the customer building and the location of the customer building where flooding is predicted to be caused are displayed on a display screen as shown in FIG. Further, detailed information such as information on the floor corresponding to the flooded height in the customer building is displayed on the display. With this detailed information, the location of the customer building, the location where flooding is predicted, and the like are displayed on the map image, so that the situation of the flood damage can be grasped more accurately.
[0023]
The flood damage information created by the flood damage information creation processing unit 15 is also transmitted to the business office terminal 2 via the communication network 3 as described above. When the flood damage information is transmitted from the monitoring center 1 at the time of occurrence of a disaster such as a torrential downpour, the office terminal 2 uses the flood damage information based on the flood damage information similarly to the display processing unit 16 of the monitoring center 1. 3), general disaster prediction information as shown in FIG. 3) and detailed information as shown in FIG. The display screen of such a display is referred to as needed by a maintenance worker stationed at a business office, for example.
[0024]
As described above, in the elevator disaster prevention system of the present embodiment, when disaster prediction information is transmitted from the information providing server 4 to the monitoring center 1, the monitoring center 1 predicts that flood damage will occur in each customer building. The customer building is specified, the floor of the customer building corresponding to the degree of flooding of the customer building, that is, the height of the flooding of the customer building is specified, and flood damage information is created based on the information. Based on the flood damage information, general disaster prediction information and its detailed information are displayed on the display of the monitoring center 1, and the flood damage information created by the monitoring center 1 is transmitted to the sales office terminal 2. Then, general disaster prediction information and its detailed information are displayed on the display of the office terminal 2. Therefore, for example, a maintenance worker stationed at a business office can refer to the display screen displayed on the display of the business office terminal 2 to accurately grasp which level of flood damage will occur in which customer building. It is possible to quickly go to only a customer building that requires measures such as evacuating the car to a floor not affected by flooding, and to take appropriate measures.
[0025]
(Second embodiment)
The elevator disaster prevention system according to the present embodiment transmits the information from the monitoring center to the elevator control device of the customer building that is predicted to be flooded when the flooding is predicted to be damaged in the customer building, and performs elevator control. The apparatus controls the elevator operation appropriately. As shown in FIG. 4, the monitoring center 1 and the elevator control device 5 of each customer building are connected via a communication network 3. In addition, each customer building is provided with a flood detector 6 for detecting flooding, and information of the flood detector 6 is supplied to the elevator control device 5 of each customer building. Since other configurations are the same as those of the above-described first embodiment, the same components as those of the first embodiment are denoted by the same reference numerals, and detailed description is omitted below.
[0026]
Also in the elevator disaster prevention system of the present embodiment, when disaster prediction information is transmitted from the information providing server 4 to the monitoring center 1, the monitoring center 1 detects a customer building that is predicted to be flooded among the customer buildings. At the same time, the floor of the customer building corresponding to the degree of flooding of the customer building, that is, the height of the flooding of the customer building is specified, and flood damage information is created based on the information. Then, in the elevator disaster prevention system of the present embodiment, the flood damage information is transmitted via the communication network 3 to the elevator control device 5 of the customer building where flood damage is predicted to occur. Here, the flood damage information transmitted from the monitoring center 1 to the elevator control device 5 of the customer building includes information indicating that the customer building is damaged by the flood and a floor of the customer building corresponding to the flood height. And the information shown.
[0027]
When the flood control information is transmitted from the monitoring center 1, the elevator control device 5 starts the flood detection of the customer building by the flood detector 6. When the inundation detector 6 detects that inundation has occurred in the customer building, the elevator control device 5 transmits the information to the monitoring center 1 and changes the operation mode of the elevator from the normal operation mode to the time of disaster. Switch to operation mode.
[0028]
When the monitoring center 1 receives information from the elevator control device 5 of each customer building, the monitoring center 1 identifies the customer building that has actually suffered flood damage based on this information, and uses the result as a result of the damaged building identification processing unit 13 or flood flooding. The inundation damage information is corrected at any time so as to be reflected in the processing in the floor identification processing unit 14. This makes it possible to improve the accuracy of predicting the ever-changing inundation damage and make the inundation damage information more realistic and highly accurate.
[0029]
When switching the operation mode of the elevator to the disaster operation mode, the elevator control device 5 firstly starts a passenger rescue operation. In this passenger rescue operation, the hall call registration is confirmed, and the car is moved to the lowest floor among the floors of the customer building where the hall call was made. Then, in order from the floor of the lowest floor where the hall call was made, the cars were sequentially stopped on the floor where the hall call was made, and the passengers waiting at the landings on each floor were put on the car and flooded. Evacuate passengers to a safe upper floor that will not be damaged.
[0030]
When it is confirmed that the rescue operation of the passenger is completed and that there is no hall call registration, the elevator control device 5 sets floors equal to or lower than the floor corresponding to the flooded height of the customer building to the nonstop floor, The floor above the floor corresponding to the height is set as the stop floor. Here, the floor corresponding to the flood height is determined based on the flood damage information transmitted from the monitoring center 1. Then, the elevator control device 5 prohibits the movement of the car to the floor set as the non-stop floor, and at the same time, above the floor set as the stop floor, that is, the floor corresponding to the flooded height. The elevator car is allowed to move only between these floors while the operation mode during disaster is continued. The car may be kept on standby on one of the floors set as the stop floor during the disaster operation mode, but the normal service will be provided on the upper floors that are not affected by flooding. , The convenience of the passengers can be improved, and especially when the customer building is a high-rise building, its usefulness is high.
[0031]
When the water in the elevator hoistway is pulled and the inundation detector 6 detects that the inundation of the customer building has been released, the elevator control device 5 sets a predetermined time from when the inundation detector 6 detects the inundation release. After the elapse, the operation mode of the elevator is returned to the normal operation mode. Here, the predetermined time is a time for compensating for an error between the detection of the inundation release by the inundation detector 6 and a state in which the elevator can be actually operated in the normal operation mode without any problem. deep. As described above, by returning the operation mode of the elevator to the normal operation mode after a lapse of a predetermined time from when the water intrusion detector 6 detects the inundation release, the elevator is operated to the extent that the operation in the normal operation mode is not hindered. When the water in the hoistway has been sufficiently drained, the operation of the elevator can be returned to the normal operation mode. When the operation of the elevator returns to the normal operation mode, the setting of the non-stop floor is released, and the car can be moved between floors from the lowest floor to the top floor of the customer building.
[0032]
When switching the operation mode of the elevator, the elevator control device 5 notifies the passengers in the car or the passengers waiting at the landings on each floor that the operation mode is to be switched. The notification of the operation mode switching is performed using a display device installed in a car or a landing, a voice guidance device, or the like. In this way, by informing the passenger of the switching of the driving mode, the inconvenience of the switching of the driving mode giving the passenger an uncomfortable feeling can be solved.
[0033]
Here, a flow of a series of processes in the elevator disaster prevention system of the present embodiment as described above will be described with reference to the flowchart of FIG.
[0034]
First, the monitoring center 1 constantly monitors whether or not disaster prediction information has been transmitted from the information providing server 4 (step S1). When disaster monitoring information is received from the information providing server 4, the same as in the first embodiment is performed. According to the method described above, a customer building which is predicted to be affected by flooding among the customer buildings is specified, and a floor of the customer building corresponding to the flooding height is specified. Then, flood damage information is created based on the information, and the flood damage information is transmitted to the elevator control device 5 of the corresponding customer building (step S2).
[0035]
When receiving the flood damage information from the monitoring center 1 (step S3), the elevator control device 5 of the customer building starts the flood detection by the flood detector 6 and actually detects the flood of the customer building based on the information from the flood detector 6. It is determined whether or not water has occurred (step S4). Then, when it is detected by the flood detector 6 that flooding has actually occurred in the customer building, the operation mode of the elevator is switched from the normal operation mode to the disaster operation mode (step S5). The fact that the switching has been performed is notified to the passenger (step S6). Then, the elevator is operated in the disaster operation mode until the flooding of the customer building is released (step S7). The information indicating that the customer building has actually been flooded is transmitted from the elevator control device 5 to the monitoring center 1. Then, the monitoring center 1 grasps the actual damage status based on this information and feeds it back to the disaster prediction information.
[0036]
In the disaster driving mode, after the above-described passenger rescue operation is performed, the non-stop floor and the stop floor are set based on the flood damage information transmitted from the monitoring center 1, and the stop floor is set. Elevator service is provided only between floors. During the operation of the elevator in the disaster operation mode, the elevator control device 5 monitors whether or not the inundation in the customer building has been canceled based on the information from the inundation detector 6 ( Step S8). When the inundation detector 6 detects that the inundation of the customer building has been released, after waiting for a predetermined time until the water in the elevator hoistway is sufficiently drained (step S9), the operation mode of the elevator is changed to a disaster. The normal operation mode is switched from the hourly operation mode (step S10), and the passenger is notified that the operation mode of the elevator has been switched (step S11). Then, the operation of the elevator is performed in the normal operation mode (step S12), and a series of processing at the time of occurrence of flooding ends.
[0037]
As described above, in the elevator disaster prevention system of the present embodiment, when disaster prediction information is transmitted from the information providing server 4 to the monitoring center 1, the monitoring center 1 predicts that flood damage will occur in each customer building. The customer building is specified, the floor of the customer building corresponding to the degree of flooding of the customer building, that is, the height of the flooding of the customer building is specified, and flood damage information is created based on the information. Then, the flood damage information is transmitted to the elevator control device 5 of the customer building where the flood damage is predicted to occur, and the elevator control device 5 controls the operation of the elevator based on the flood damage information. Therefore, the operation of the elevator is controlled in an optimal state according to the degree of flood damage in each customer building, so that passengers can be safely evacuated and elevator services are provided on floors that are not affected by flood damage. Can be continued to improve convenience. Further, in this elevator disaster prevention system, the elevator control device 5 of each customer building autonomously controls the operation of the elevator in response to the flood damage information from the monitoring center 1, so that the burden on the maintenance worker is increased. Can also be significantly reduced.
[0038]
In the above description, an example is described in which the monitoring center 1 is used to specify the floor to be damaged by flooding in the customer building. However, the floor to be damaged by flooding is specified by the elevator control device 5 of each customer building. May be performed. Also in this case, similarly to the above example, the elevator control device 5 can control the operation of the elevator in an optimal state according to the degree of flood damage of the customer building.
[0039]
