Description

[[Technical Field]]

[0001] Embodiments of the present invention relate to an elevator system. [[Background Art]]

[0002] When a disaster such as an earthquake occurs and an elevator makes an emergency stop, a so-called "car entrapment accident", in which passengers are trapped inside the car, may occur. When an abnormality caused by the impact of a disaster such as a car entrapment accident occurs, a monitoring center that monitors the operation status of the car causes an indicator installed in the car to display disaster response information including information indicating the status of the car resulting from the disaster and information for responding to the abnormality caused by the disaster. By displaying the disaster response information on the indicator, passengers in the car can grasp the status of the car they are riding in and how to respond to the occurred abnormality.

[0003] Here, a power outage may occur due to the occurred disaster, power supply to the indicator in the car is not performed, and the indicator may be unable to display the disaster response information. In such a case, the monitoring center uses an Internet line to connect to a mobile terminal (e.g., a smartphone) carried by a passenger, and causes the smartphone to directly display the disaster response information. Therefore, even when power is not supplied to the indicator, passengers in the car can grasp the status of the car they are riding in and how to respond to the occurred disaster.

[0004] However, communication conditions often deteriorate inside the car, and congestion of Internet lines caused by the occurred disaster may make communication between the monitoring center and the passenger's smartphone difficult, making it impossible to display the disaster response information on the smartphone. In such a case, passengers in the car cannot grasp the status of the car they are riding in or how to respond to the abnormality caused by the disaster. Therefore, even when communication between the monitoring center and the passenger's smartphone is difficult, it is desirable that passengers in the car can grasp the status of the car they are riding in and how to respond to the abnormality caused by the occurred disaster.

[0006] Therefore, the problem that the present invention aims to solve is to provide an elevator system that allows passengers inside an elevator car to understand the status of the elevator car they are riding in and how to respond to any abnormalities caused by a disaster, even when communication between the monitoring center and the mobile terminals of passengers inside the elevator car being monitored by the monitoring center is difficult. [Means for solving the problem]

[0007] An elevator system according to one embodiment comprises an elevator control device that controls the operation of an elevator car and is communicatively connected to a monitoring center that monitors the operation of the elevator car, and a portable terminal carried by a passenger inside the elevator car and communicatively connected to the elevator control device. The elevator control device comprises a storage means, a disaster detection means, and a communication means. The storage means stores disaster information received from the monitoring center when a disaster occurs at the location where the elevator car is installed, and abnormal response information for passengers inside the elevator car to respond to abnormalities caused by the disaster. The disaster detection means detects a disaster that has occurred at the location where the elevator car is installed. When a disaster is detected by the disaster detection means, the communication means transmits the disaster information and abnormal response information stored in the storage means to a portable terminal carried by a passenger inside the elevator car via wireless communication. The disaster information is stored in the storage means in association with the time the disaster information was received from the monitoring center. If communication with the monitoring center is interrupted, the communication means transmits the latest disaster information stored in the storage means to the mobile terminal.

[0009] The embodiments will be described below with reference to the drawings. It should be noted that the disclosure is merely an example, and the invention is not limited by the contents described in the embodiments below. Modifications that a person skilled in the art can easily conceive are naturally included within the scope of the disclosure. In order to make the explanation clearer, the size, shape, etc. of each part may be schematically represented in the drawings with modifications from the actual embodiments. In some cases, the same reference numerals are used for corresponding elements in multiple drawings, and detailed explanations are omitted.

[0010] Figure 1 is a block diagram showing the configuration of an elevator system according to an embodiment. As shown in Figure 1, the elevator system includes a monitoring center 10, an elevator control device 20, and a portable terminal 30.

[0011] The monitoring center 10 is connected to the elevator control device 20 by a wired line or wireless communication network and monitors the operation of the elevator car 11 controlled by the elevator control device 20. When a disaster occurs at the location where the elevator car 11 is installed, the monitoring center 10 acquires disaster information related to the disaster and transmits the acquired disaster information to the elevator control device 20. The disaster information includes information indicating the type and scale of the disaster. The disaster information may also include information indicating the estimated time required to rescue passengers P trapped inside the elevator car 11.

[0012] The elevator car 11 moves up and down within the hoistway under the control of the elevator control device 20, driven by a hoisting machine (not shown). Inside the elevator car 11, there are input buttons (not shown) for registering car calls and opening and closing the doors of the elevator car 11. As will be described in detail later, after the operation mode of the elevator car 11 is switched to rescue operation mode by a monitor at the monitoring center 10, passengers P in the elevator car 11 can move the elevator car 11 to the nearest floor by performing predetermined operations on the input buttons.

[0013] The elevator control device 20 consists of a computer equipped with a CPU, ROM, RAM, etc., and controls the entire elevator. In this embodiment, the elevator control device 20 includes a communication unit 21, a storage unit 22, a disaster detection unit 23, a terminal detection unit 24, and an operation control unit 25.

[0014] The communication unit 21 is connected to the monitoring center 10 via a wired line or a wireless communication network and transmits car status information to the monitoring center 10. The communication unit 21 is also connected to the mobile terminal 30 inside the elevator car 11 via any short-range wireless communication method and transmits disaster information and abnormal response information (described later) to the mobile terminal 30. Examples of short-range wireless communication methods include Wi-Fi® and Bluetooth®.

[0015] The storage unit 22 stores disaster information received from the monitoring center 10 and abnormal response information that indicates how passengers in the elevator car 11 should respond to abnormalities caused by the disaster indicated by the disaster information. The abnormal response information includes information that indicates an operation manual for operating the elevator car 11 in control operation mode or rescue operation mode if the elevator car 11 makes an emergency stop while in operation. The storage unit 22 has a disaster information table T1 in which disaster information received from the monitoring center 10 and the time of receipt of the disaster information are stored in association.

[0016] Further, the storage unit 22 stores hall calls registered by operations of unillustrated hall call buttons provided at halls of each floor, and car calls registered by operations of unillustrated car call buttons provided in the car 11.

[0017] The disaster detection unit 23 detects a disaster such as an earthquake that has occurred in a building (location) where the car 11 is installed. For example, the disaster detection unit 23 acquires an earthquake signal transmitted by a seismic detector installed at the bottom of the hoistway of the elevator, and detects the occurrence of an earthquake based on the acquired earthquake signal.

[0018] The terminal detection unit 24 detects a mobile terminal 30 carried by a passenger P in the car 11. The terminal detection unit 24 detects the mobile terminal 30 by determining whether there is any mobile terminal 30 carried by a passenger P in the car 11 based on terminal number information indicating the number of mobile terminals 30 that can communicate with the communication unit 21 via short-range wireless communication.

[0019] The operation control unit 25 performs operation control such as moving the car 11 to each floor based on the hall call or car call stored in the storage unit 22. Further, when a disaster such as an earthquake is detected by the disaster detection unit 23, the operation control unit 25 switches the operation mode of the car 11 to an emergency control operation mode in which the car 11 is moved to an evacuation floor or stopped at the nearest floor.

[0020] The mobile terminal 30 is a terminal carried by the passenger P riding in the car 11, and is a general mobile phone, smartphone, or the like. The mobile terminal 30 includes a communication unit 31, a display unit 32, an input unit 33, and a storage unit 34.

[0021] The communication unit 31 is connected to the elevator control device 20 via any short-range wireless communication method, and transmits attribute information, which will be described later, to the elevator control device 20. The display unit 32 is a display screen of the mobile terminal 30, and displays disaster information, abnormality response information, and the like received from the elevator control device 20.

[0022] The input unit 33 consists of various keys and buttons and is an input interface that allows passenger P to input data and give instructions to the mobile terminal 30. If a touch panel display is used for the display unit 32, information (data) can be input on the display unit 32.

[0023] The memory unit 34 stores various programs necessary for processing the mobile terminal 30, as well as data entered into the input unit 33. The memory unit 34 also stores an application program that can display disaster information and abnormal response information received from the elevator control device 20. Passenger P can set attribute information on the application. Attribute information is information indicating the attributes of passenger P, including the passenger P's gender, age, special notes (e.g., pregnant woman, stroller user, wheelchair user, etc.), and is entered via the input unit 33 and stored in the memory unit 34.

[0024] Figure 2 shows an example of a disaster information table T1 stored in the memory unit 22 of the elevator control device 20. The disaster information table T1 stores disaster information and the time it was received, associated with each other.

[0025] The first row L1 of the disaster information table T1 shows that disaster information "Disaster Information a" was received at 10:10 on January 17, 2025. Similarly, the rows from the second row onward show that disaster information b through d were received at 5-minute intervals prior to 10:10 on January 17, 2025.

[0026] Next, we will explain how this system works. Figure 3 is a flowchart illustrating the operation of this system. The processes shown in this flowchart are primarily executed at regular intervals by the elevator control device 20, which is a computer. Here, we assume a scenario in which a disaster occurs near the building where the elevator car 11 is installed, and passengers P are trapped inside the elevator car 11.

[0027] The communication unit 21 of the elevator control device 20 constantly acquires car control information from the operation control unit 25, regardless of whether a disaster has occurred (step S1). The car control information includes information indicating the current operating mode of the elevator car 11. Operating modes of the elevator car 11 include normal operation mode, controlled operation mode, rescue operation mode, emergency stop state, etc.

[0028] Furthermore, the terminal detection unit 24 of the elevator control device 20 determines whether or not there is a mobile terminal 30 inside the elevator car 11, regardless of whether or not a disaster has occurred (step S2). Specifically, the terminal detection unit 24 obtains terminal count information from the communication unit 21, which indicates the number of mobile terminals 30 that can communicate with the elevator control device 20. If the number of mobile terminals 30 that can communicate with the elevator control device 20, as indicated in the terminal count information, is one or more, the terminal detection unit 24 determines that there is a mobile terminal 30 inside the elevator car 11.

[0029] If it is determined that there is a mobile terminal 30 inside the elevator car 11 (Yes in step S2), the communication unit 21 of the elevator control device 20 determines whether it is possible to communicate normally with the monitoring center 10 (step S3). The communication unit 21 sends a confirmation signal to the monitoring center 10, for example, at predetermined time intervals to check whether communication is being performed normally. If the communication unit 21 receives a signal corresponding to the confirmation signal from the monitoring center 10 within a predetermined time after the transmission of the confirmation signal, it determines that it is possible to communicate normally with the monitoring center 10.

[0030] If it is determined that communication with the monitoring center 10 is possible (Yes in step S3), the communication unit 21 receives disaster information from the monitoring center 10 regarding a disaster that occurred near the building (step S4). Upon receiving disaster information from the monitoring center 10, the communication unit 21 refers to a timer (not shown) to obtain the time the disaster information was received. The communication unit 21 associates the disaster information received from the monitoring center 10 with the time the disaster information was received and stores it in the disaster information table T1.

[0031] The disaster detection unit 23 determines whether or not a disaster has been detected by sensors installed within the building (step S5). Specifically, the disaster detection unit 23 determines that a disaster has been detected when it receives an earthquake signal from an earthquake detector.

[0032] If it is determined that a disaster has been detected (Yes in step S5), the operation control unit 25 switches the operation mode of the elevator car 11 from normal operation mode to controlled operation mode and starts controlled operation (step S6). Specifically, if the disaster detection unit 23 receives an earthquake signal and determines that a disaster has been detected, the operation control unit 25 switches the operation mode of the elevator car 11 to controlled operation mode and moves the elevator car 11 from its current position to the nearest floor.

[0033] The communication unit 21 transmits the latest disaster information stored in the storage unit 22, anomaly response information, and the detection results from the disaster detection unit 23 to a mobile terminal 30 that can communicate with the elevator control device 20 (step S7). The detection results from the disaster detection unit 23 include information indicating the type of disaster detected by the disaster detection unit 23 and the time at which the disaster was detected. When the mobile terminal 30 receives the disaster information, anomaly response information, and detection results, it displays the received disaster information, anomaly response information, and detection results on the display unit 32, and reads pre-configured attribute information from the storage unit 34 within the application and transmits it to the elevator control device 20.

[0034] The communications unit 21 receives attribute information from a mobile terminal 30 held by passenger P inside the elevator car 11 (step S8).

[0035] The communication unit 21 transmits car status information indicating the status of the elevator car 11 to the monitoring center 10 (step S9). The car status information includes car control information acquired from the operation control unit 25, call information indicating the call registration status stored in the storage unit 22, detection results from the disaster detection unit 23, terminal number information, and attribute information. After executing the process in step S9, the elevator control device 20 terminates the process there.

[0036] Returning to the process in step S5, if it is determined that no disaster has been detected in the building (No. in step S5), and the elevator car 11 is operating in controlled operation mode, the operation control unit 25 switches from controlled operation mode to normal operation mode and terminates controlled operation of the elevator car 11 (step S10).

[0037] After the processing in step S10, if the communication unit 21 has been transmitting disaster information, abnormal response information, and detection results to the mobile terminal 30 inside the elevator car 11, it terminates the transmission of disaster information, abnormal response information, and detection results (step S11). After executing the processing in step S11, the communication unit 21 executes the processing in step S9.

[0038] Returning to the process in step S3, if it is determined that communication with the monitoring center 10 cannot be performed properly (No. in step S3), the disaster detection unit 23 determines whether or not a disaster has been detected in the building where the elevator car 11 is installed, similar to the process in step S5 (step S12).

[0039] If it is determined that a disaster has been detected in the building (Yes in step S12), the operation control unit 25 switches the operation mode of the elevator car 11 from normal operation mode to controlled operation mode and starts controlled operation (step S13), similar to the process in step S6.

[0040] The communication unit 21 transmits the most recent disaster information stored in the memory unit 22, the abnormal response information, and the detection results from the disaster detection unit 23 to the portable terminal 30 that communicates with the elevator control device 20 inside the elevator car 11 (step S14). The most recent disaster information is the disaster information with the most recent reception time among the disaster information received while the monitoring center 10 and the elevator control device 20 were communicating normally and stored in the memory unit 22.

[0041] As described above, at step S14, the communication unit 21 cannot communicate properly with the monitoring center 10 and therefore cannot acquire new disaster information. Accordingly, in the processing of step S14, the communication unit 21 transmits the most recent disaster information from the disaster information table T1 stored in the storage unit 22 to the mobile terminal 30. At this time, the mobile terminal 30, having received the disaster information and anomaly response information, displays the disaster information, anomaly response information, and detection results on the display unit 32. After executing the processing of step S14, the elevator control device 20 terminates the processing at this point.

[0042] On the other hand, if it is determined that no disaster has been detected in the building (No. in step S12), and the elevator car 11 is operating in controlled operation mode, the operation control unit 25 switches from controlled operation mode to normal operation mode and terminates controlled operation of the elevator car 11, similar to the process in step S10 (step S15).

[0043] After the processing in step S15, if the communication unit 21 has been transmitting disaster information, abnormal response information, and detection results to the mobile terminal 30 inside the elevator car 11, it terminates the transmission of disaster information, abnormal response information, and detection results, similar to the processing in step S11 (step S16). After executing the processing in step S16, the elevator control device 20 terminates the processing at this point.

[0044] In step S5, the disaster detection unit 23 detected disasters based on signals from various detectors installed in the building, but it may also detect disasters based on received disaster information.

[0045] Furthermore, although the flowchart shown in Figure 3 was described above as being executed at regular intervals, it may also be executed when the elevator car 11 closes, that is, when passengers P get on or off the elevator car 11. In addition, if a load sensor for detecting the load inside the elevator car 11 is provided on the floor of the elevator car 11, the flowchart shown in Figure 3 may be executed when the load inside the elevator car 11 changes.

[0046] Figure 4 shows an example of a screen displayed on the mobile device 30 when an earthquake is detected. Figure 4(a) shows the disaster information screen displayed on the display unit 32 of the mobile terminal 30 when an earthquake is detected in the building where the elevator car 11 is installed and the monitoring center 10 and the elevator control device 20 are able to communicate normally. The disaster information screen is displayed on the display unit 32 via an application installed on the mobile terminal 30.

[0047] Disaster column 32a is a column that displays the type of disaster that has occurred, based on the detection results of the disaster detection unit 23. In Figure 4(a), the disaster detection unit 23 has received an earthquake signal from the earthquake detector and detected an earthquake, so "earthquake" is displayed in disaster column 32a.

[0048] The disaster information section 32b is a section for displaying details of disaster information received from the monitoring center 10. When a passenger P presses the disaster information section 32b, the display unit 32 of the mobile terminal 30 displays the details of the latest disaster information received from the monitoring center 10 (for example, a regional earthquake warning).

[0049] Sensor field 32c is the field where the detection results of the disaster detection unit 23 are displayed. When passenger P presses sensor field 32c, the display unit 32 displays the time when the disaster detection unit 23 detected the disaster.

[0050] The response information field 32d is a field where abnormal response information received from the monitoring center 10 is displayed. When passenger P presses the response information field 32d, the elevator operation manual (abnormal response information), which includes how to deal with the situation inside the elevator car 11 according to the elevator car 11's current operating mode, is displayed. For example, if the elevator car 11 is operating in rescue mode, the elevator operation manual will show passenger P, using images and videos, how to operate the input buttons to move the elevator car 11 to the nearest floor.

[0051] Figure 4(b) shows the screen displayed when an earthquake is detected in the building where the elevator car 11 is installed and communication between the monitoring center 10 and the elevator control device 20 is lost.

[0052] In comparison with Figure 4(a), Figure 4(b) shows that the display in the disaster information section 32b has changed to "*Communication interrupted". As shown in Figure 4(b), when communication between the elevator control device 20 and the monitoring center 10 is interrupted, the disaster information section 32b displays a message indicating that communication has been interrupted. In this case, when passenger P presses the disaster information section 32b, the details of the disaster information received immediately before communication with the monitoring center 10 was interrupted are displayed on the display unit 32.

[0053] Conventionally, when a disaster causes a power outage or internet congestion, passengers inside the elevator car are unable to ascertain the status of the elevator car they are riding in or how to respond to the abnormality caused by the disaster. In the elevator system according to this embodiment, even when a disaster causes a power outage or internet congestion, disaster information and abnormality response information are transmitted wirelessly from the elevator control device 20 to the mobile terminal 30 held by the passenger. This allows the passenger P holding the mobile terminal 30 to ascertain the status of the elevator car 11 they are riding in and how to respond to the abnormality caused by the disaster.

[0054] Furthermore, even if communication between the elevator control device 20 and the monitoring center 10 is interrupted, the elevator system according to this embodiment can transmit the disaster information received immediately before to the mobile terminal 30, thereby allowing passenger P, who is carrying the mobile terminal 30, to understand the status of the elevator car 11 in which they are riding.

[0055] In addition, in the elevator system according to this embodiment, the elevator control device 20 acquires car status information indicating the status of the elevator car 11 using wireless communication and transmits it to the monitoring center 10. This allows the monitoring personnel at the monitoring center 10 to understand the status of the elevator car 11. Furthermore, even if communication with the elevator control device 20 is interrupted, the monitoring personnel at the monitoring center 10 can understand the status of the elevator car 11 immediately before the communication was interrupted by the car status information received immediately before the communication was interrupted.

[0056] Furthermore, because the car status information includes attribute information, the monitors at the monitoring center 10 can understand the attributes of the passenger P inside the car 11.

[0057] In addition to attribute information, information indicating whether the mobile terminal 30 can contact the outside using a public network or the like may also be transmitted to the elevator control device 20. When this information is transmitted to the monitoring center 10, the monitors at the monitoring center 10 can determine whether the passenger P inside the elevator car 11 can contact the outside and decide on appropriate actions, such as going to rescue them.

[0058] Figure 5 shows a specific example of what happens when an elevator car entrapment accident occurs. An earthquake has just occurred, and as a result of the earthquake, elevator car 11, carrying passenger P, has come to an emergency stop between the 3rd and 4th floors, resulting in a passenger being trapped inside the car. Additionally, communication between the monitoring center 10 and the elevator control device 20 has been lost due to the earthquake.

[0059] The monitor at monitoring center 10, based on the car status information received from the elevator control device 20 before communication was lost, understands that passenger P is inside the elevator car 11. The monitor at monitoring center 10 understands that the earthquake was strong enough to disrupt communication between monitoring center 10 and the elevator control device 20, and that passenger P is inside the elevator car 11, and dispatches workers to rescue passenger P inside the elevator car 11.

[0060] The elevator control device 20 transmits disaster information, abnormal response information, and detection results received before communication with the monitoring center 10 is lost to a portable terminal 30 held by a passenger P riding in the elevator car 11, using short-range wireless communication.

[0061] Passenger P inside elevator car 11 understands, through the display of disaster information and detection results on the mobile terminal 30, that the disaster that occurred is an earthquake, information including the magnitude of the earthquake, and that elevator car 11 has made an emergency stop due to the earthquake. In addition, passenger P understands, through the display of abnormal response information on the mobile terminal 30, how to move elevator car 11 to the nearest floor when elevator car 11 is operating in rescue operation mode.

[0062] When a worker dispatched from the monitoring center 10 arrives at the installation site of the elevator car 11, after confirming safety, manually switches the operation of the elevator car 11 to rescue operation mode. At this time, a signal indicating that the operation mode of the elevator car 11 has been switched to rescue mode is transmitted to the elevator control device 20. When the operation mode of the elevator car 11 is switched to rescue operation mode, the elevator control device 20 transmits abnormal response information corresponding to the rescue operation mode to the mobile terminal 30.

[0063] Passenger P inside elevator car 11 sees the elevator operation manual corresponding to the rescue operation mode displayed on the mobile terminal 30, and learns how to move the emergency-stopped elevator car 11 to the nearest floor. Passenger P operates the input buttons inside elevator car 11 according to the instructions displayed on the mobile terminal 30 for moving elevator car 11 to the nearest floor. In response to the operation of the input buttons, elevator car 11 moves to the nearest floor, 3F or 4F, and the doors open. As a result, passenger P escapes from elevator car 11 where the car entrapment accident occurred and is evacuated.

[0064] Conventionally, in the event of an elevator car entrapment, passengers inside the car would contact an external party, such as a monitoring center, via an intercom or similar device to understand the abnormality that occurred in the car and how to respond to it. The elevator system according to this embodiment transmits abnormality response information to the passenger P's mobile terminal 30, allowing the passenger P to understand how to respond to an abnormality that occurred in the car 11 without having to contact an external party. Furthermore, even if it is not possible to contact an external party due to an intercom malfunction or the like, the elevator system according to this embodiment can still allow the passenger P to understand the abnormality that occurred in the car 11 and how to respond to it.

[0065] Furthermore, in this embodiment, even if the monitoring center 10 and the passenger P's mobile terminal 30 are unable to communicate normally, the elevator system can still allow the passenger P to understand how to respond to any abnormalities that occur in the elevator car 11.

[0066] In the embodiment described above, the functions of the elevator control device 20 may also be provided by a communication device installed near the elevator car 11. In this case, the distance between the mobile terminal 30 inside the elevator car 11 and the communication device is shorter than the distance between the mobile terminal 30 and the elevator control device 20, reducing the effect of signal attenuation due to distance. This makes it possible to communicate with the mobile terminal 30 using short-range wireless communication more reliably.

[0067] According to at least one embodiment described above, even when communication between the monitoring center and the mobile terminals of passengers inside the elevator car being monitored by the monitoring center is difficult, it is possible to provide an elevator system that allows passengers inside the elevator car to understand the status of the elevator car they are riding in and how to respond to any abnormalities caused by a disaster.

[0068] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These embodiments can be carried out in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
