Description
Technical Field
The present invention relates to an elevator status information communication device and a remote monitoring system, and more particularly, to an elevator status information communication device and a remote monitoring system for transmitting elevator status information to a monitoring center using a portable communication terminal.
Background
In a remote monitoring system for elevators, a plurality of elevators are connected to a remote monitoring center via a public line network such as an analog telephone network or a portable telephone network, and thereby the operation states, failure states, and the like of the respective elevators are monitored collectively via the public line network. In such a remote monitoring system, when an abnormality occurs in an elevator or when a passenger is trapped, the information is reported to a monitoring center via a public line network, and a serviceman is instructed to be dispatched from the monitoring center to the elevator.
However, in the case of a large-scale disaster such as an earthquake, the public line network may be crowded and difficult to communicate, or the public line network may not be available due to damage or power failure of a base station of the public line network. In such a situation, in order to recover an elevator or the like in which an abnormality occurs as soon as possible, a method and a configuration for obtaining the state information of the elevator in a state where communication with the monitoring center is impossible are required.

Disclosure of Invention
Problems to be solved by the invention
The techniques described in patent documents 1 and 2 are premised on the use of a public communication network, and when the public communication network is congested and communication is difficult or the public communication network cannot be used, it is difficult to transmit elevator status information to a monitoring center. In addition, in the technique described in patent document 3, the state information of the elevator can be transmitted only to a range where the external display device can be visually recognized, and it is difficult to transmit the state information of the elevator to the monitoring center. In the technique described in patent document 4, it is possible to transmit abnormality information of an elevator to other elevators without using a public network.
However, in a large-scale disaster, it is considered that a large number of abnormalities occur in a plurality of elevators, and a large amount of abnormality information of the elevators exists between the plurality of elevators. Therefore, even if the serviceman visits the abnormality information of the ad hoc network between the plurality of elevators, the abnormality information of the ad hoc network may include abnormality information of low importance, abnormality information of a place far from the place where the serviceman is present, and the like, and it is difficult to find only abnormality information of high priority or importance from a large amount of abnormality information, and the response to the abnormality of the elevator is delayed.
In addition, in the case where the public line network cannot be used, or in the case where the communication device of the elevator to the monitoring center has failed, the state information of the elevator cannot be transmitted to the monitoring center, and the response to the elevator abnormality is delayed.

Detailed Description
Fig. 1 shows an overall configuration of an elevator remote monitoring system 100 according to embodiment 1 of the present invention. As shown in fig. 1, the remote monitoring system 100 includes: elevators 1A, 2A, 3A provided in a plurality of buildings 1, 2, 3, respectively; a monitoring center 4 that collectively monitors the operation states, failure states, and the like of the elevators 1A, 2A, 3A; state information communication devices 1B, 2B, and 3B that acquire state information regarding occurrence of an abnormality such as a failure in the elevators 1A, 2A, and 3A and occurrence of a passenger getting stuck, and transmit the state information to the monitoring center 4; a public line network 5 for communication between the elevators 1A, 2A, 3A and the monitoring center 4; and a mobile communication terminal 6, for example, a mobile communication terminal 6 such as a smartphone or a personal computer, which transmits and receives status information among the elevators 1A, 2A, 3A.
In the remote monitoring system 100, the operation conditions, failure conditions, and the like of the elevators 1A, 2A, 3A are monitored collectively through the public network 5 by the monitoring center 4. Therefore, for example, when an abnormality such as a failure or a passenger is trapped in the elevator 1A, the state information about the abnormality or the passenger is transmitted to the monitoring center 4 through the public network 5, and a serviceman is requested from the monitoring center 4 to the elevator maintenance management company.
In addition, when a large-scale disaster such as an earthquake occurs in the area where the elevator 1A is installed, and the public line network 5 is congested and communication is difficult, or when the public line network 5 cannot be used due to damage or power failure of the base station of the public line network 5, that is, when the elevator 1A and the monitoring center 4 cannot communicate with each other, the state information of the elevator 1A is transmitted to the other elevator 2A by the portable communication terminal 6.
When the mobile communication terminal 6 is located in the vicinity of the elevator 1A, the state information of the elevator 1A is received from the elevator 1A. When the portable communication terminal 6 moves to the vicinity of the elevator 2A where the public line network 5 can be used, the state information of the elevator 1A is transmitted to the elevator 2A. The elevator 2A transmits the status information of the elevator 1A received from the portable communication terminal 6 to the monitoring center 4 through the public network 5. The details of the control of the transmission and reception of the state information when the elevator 1A and the monitoring center 4 cannot communicate with each other will be described later.
Next, details of the state information communication devices 1B, 2B, and 3B will be described with reference to fig. 2. The elevators 1A, 2A, and 3A are provided with status information communication devices 1B, 2B, and 3B that transmit status information such as an abnormality or a passenger getting stuck of the elevators 1A, 2A, and 3A to the monitoring center 4, respectively. Since the status information communication devices 1B, 2B, and 3B have the same configuration and perform the same control, the status information communication device 1B will be described below.
Fig. 2 shows a specific configuration of the state information communication apparatus 1B. As shown in fig. 2, the state information communication device 1B includes a state information acquisition unit 11 that acquires state information of the elevator 1A from the control unit 1A of the elevator 1A, a monitoring communication unit 12 that transmits the state information of the elevator 1A to the monitoring center 4, a state information accumulation unit 13 that accumulates the state information of the elevator 1A, a state information transmission unit 14 that transmits the state information of the elevator 1A to the portable communication terminal 6, and a state information reception unit 15 that receives state information of other elevators 2A and 3A from the portable communication terminal 6.
The state information acquiring unit 11 is connected to the control unit 1A of the elevator 1A via a signal line, and acquires state information on an abnormality such as a failure occurring in the elevator 1A and passengers getting trapped from the control unit 1A of the elevator 1A. Fig. 3 shows an example of the state information. As shown in fig. 3, the state information of the elevator 1A is configured as a state information record D1, and the state information record D1 includes an elevator ID for identifying the elevator 1A, position information in which the elevator 1A is installed, an elevator state indicating whether the state of the elevator 1A is normal or abnormal, information indicating whether passengers are present in the car at the time of information acquisition, flag information indicating whether the state information is notified to the monitoring center 4, and the like. Further, information other than these may be included.
For the information communication between the elevator 1A and the state information acquiring unit 11, communication cables defined by communication standards such as wireless LAN, short-range wireless communication such as Bluetooth (registered trademark), Ethernet (registered trademark), RS-232C, RS-422, RS-485, and USB may be used, for example.
The monitoring communication unit 12 is connected to the status information acquisition unit 11, and transmits the status information acquired by the status information acquisition unit 11 to the monitoring center 4 via the public network 5. When the public line network 5 can be used, the monitoring communication unit 12 transmits the status information to the monitoring center 4 via the public line network 5 as described above, but when the public line network 5 cannot be used, outputs an instruction to enable the transmission function to the status information transmission unit 14.
The state information storage unit 13 is connected to a state information acquisition unit 11, a state information transmission unit 14, and a state information reception unit 15. The state information accumulation unit 13 has a state information recording unit D as a storage area for storing the state information record D1. The state information storage unit 13 stores the state information of the elevator 1A acquired by the state information acquisition unit 11 in the state information recording unit D. When the state information receiving unit 15 receives the state information of the other elevators 2A and 3A, the state information accumulating unit 13 also accumulates the state information of the elevators 2A and 3A in the state information recording unit D when the relationship between the elevator 1A and the other elevators 2A and 3A satisfies a predetermined condition.
The state information transmitting unit 14 has a function of transmitting the state information accumulated in the state information accumulating unit 13 to the mobile communication terminal 6. The status information transmitting unit 14 disables the transmission function when the public line network 5 can be used, and enables the transmission function by an instruction from the monitoring communication unit 12 when the public line network 5 cannot be used.
The state information receiving unit 15 receives the state information of the other elevators 2A and 3A from the portable communication terminal 6. For communication between the state information transmitter 14 and the state information receiver 15 and the portable communication terminal 6, short-range wireless communication such as wireless LAN and Bluetooth (registered trademark) is used. The detailed control of the monitoring communication unit 12, the status information transmitting unit 14, and the status information receiving unit 15 will be described later.
The mobile communication terminal 6 has a short-range wireless communication function, and is provided with a communication application for communicating with the status information transmitting unit 14 and the status information receiving unit 15 in advance. The communication application performs communication control with the state information transmitting unit 14 and the state information receiving unit 15, and storage control for temporarily storing state information communicated with the state information transmitting unit 14 and the state information receiving unit 15 in the mobile communication terminal 6. The communication application is preferably incorporated into another application that can be used in a large-scale disaster such as an earthquake, and is downloaded in advance to the mobile communication terminal 6 used by a general user.
Next, the acquisition of the status information of the elevators 1A, 2A, 3A and the transmission of the status information to the monitoring center 4 will be described. First, fig. 4 shows a flowchart of the state information acquisition control of the elevator 1A.
In step S101 of the flowchart of fig. 4, the state information acquiring unit 11 acquires the elapsed time since the state information was acquired from the elevator 1A last time, compares the elapsed time with a predetermined time set in advance, and determines whether or not the elapsed time exceeds the predetermined time. When the elapsed time exceeds the predetermined time (yes), the state information acquisition unit 11 proceeds to step S102. When the elapsed time does not exceed the predetermined time (no), the state information acquisition unit 11 counts the elapsed time and returns to the initial state.
In step S102, the state information acquiring unit 11 acquires the latest state information from the elevator 1A, that is, the state information such as whether an abnormality has occurred in the elevator 1A or whether passengers are trapped from the control unit 1A of the elevator 1A, and proceeds to step S103.
In step S103, the state information acquisition unit 11 stores the latest state information acquired in the state information storage unit 13. That is, the state information accumulated in the state information accumulation unit 13 is updated to the latest state information. Therefore, the state information stored in the state information storage unit 13 is always the latest state information. As shown in fig. 3, the state information record D1 updates information on each item of elevator state, presence/absence of passengers, and flag information. Here, the elevator state is "abnormal", the presence or absence of a passenger is "present", and the notification to the monitoring center 4 is "not".
Next, fig. 5 shows communication control for transmitting the state information of the elevator 1A to the monitoring center 4. In step S201 of the flowchart of fig. 5, the state information communication device 1B checks the state information recording unit D of the state information storage unit 13 at predetermined intervals, and proceeds to step S202.
In step S202, the state information communication device 1B checks the state information recording unit D, and determines whether or not the following state information exists: the notification (flag information) to the monitoring center 4 is "none", and the elevator state is "abnormal" or the presence of a passenger is "present". Here, as in the state information record D1 shown in fig. 3, since the elevator state is "abnormal", the presence or absence of a passenger is "present", and the notification to the monitoring center 4 is "not" (yes), the state information communication device 1B proceeds to step S203. Further, in the case where such state information does not exist (no), the state information communication apparatus 1B returns to the initial state.
In step S203, the monitoring communication unit 12 transmits the status information to the monitoring center 4 via the public line network 5, and proceeds to step S204, and in step S204, checks whether or not the transmission to the monitoring center 4 is successful.
When the status information is transmitted from the monitoring communication unit 12 to the monitoring center 4, the monitoring center 4 returns a signal indicating that the transmission is successful to the monitoring communication unit 12. If there is no reply, the transmission from the monitoring communication unit 12 to the monitoring center 4 is retried a predetermined number of times. If there is no reply from the monitoring center 4, it is determined that the transmission from the monitoring communication unit 12 to the monitoring center 4 has failed. As a cause of the transmission failure, there is a large-scale disaster such as occurrence of an earthquake. When a large-scale disaster occurs, the public line network 5 may be congested and communication may be difficult, and the public line network 5 may be unusable due to damage or power failure of the base station of the public line network 5. Even if a large-scale disaster does not occur, transmission to the monitoring center 4 is not possible due to a failure of the communication device of the monitoring communication unit 12 or the like.
Then, when the transmission from the monitoring communication unit 12 to the monitoring center 4 is successful (yes), the monitoring communication unit 12 proceeds to step S205, updates the notification (flag information) of the status information to the monitoring center 4 to "already", and proceeds to step S206.
In step S206, the monitoring communication unit 12 deactivates the transmission function of the status information transmission unit 14 and returns to the initial state. That is, since the monitoring communication unit 12 of the elevator 1A can normally transmit the status information to the monitoring center 4, the status information communication device 1B does not need to transmit the status information to the portable communication terminal 6. On the other hand, when the transmission from the monitoring communication unit 12 to the monitoring center 4 has failed (no), the monitoring communication unit 12 proceeds to step S207, and activates the transmission function of the state information transmission unit 14 to return to the initial state.
Next, transmission control by the state information transmitting unit 14 will be described with reference to a flowchart of fig. 6. When the transmission function of the state information transmitting unit 14 is enabled by the monitoring communication unit 12 in step S207 of fig. 5, the state information transmitting unit 14 starts searching for the mobile communication terminal 6 having the communication application installed in the vicinity of the elevator 1A in step S301 of the flowchart of fig. 6, and the process proceeds to step S302. That is, the mobile communication terminal 6 with the communication application installed is searched for among the mobile communication terminals 6 held by pedestrians passing near the elevator 1A.
If a communicable mobile communication terminal 6 is found from the search result of the mobile communication terminal 6 in step S302 (yes), the state information transmitting unit 14 proceeds to step S303 to transmit the state information to the mobile communication terminal 6. At this time, when a plurality of mobile communication terminals 6 are found, the state information is transmitted to all of the mobile communication terminals 6. When receiving the state information from the state information transmitting unit 14, the mobile communication terminal 6 stores the state information. In addition, when the portable communication terminal 6 capable of communication is not found (no), the state information transmitting unit 14 returns to the initial state.
Then, as shown by a broken line in fig. 1, the pedestrian having the mobile communication terminal 6 moves from the elevator 1A in which the disaster is encountered to the area where the elevator 2A in which the disaster is not encountered. That is, the pedestrian located in the disaster area moves to evacuate from the disaster area to the non-disaster area, and thereby the mobile communication terminal 6 moves from the elevator 1A in the disaster area to the elevator 2A in the non-disaster area.
In this case, when the number of the mobile communication terminals 6 storing the state information of the elevator 1A is small, the probability that the mobile communication terminal 6 moves from the elevator 1A to the elevator 2A is low, but by increasing the number of the mobile communication terminals 6 storing the state information of the elevator 1A, that is, by transmitting the state information of the elevator 1A to the plurality of mobile communication terminals 6, the probability that the mobile communication terminal 6 moves from the elevator 1A to the elevator 2A can be increased.
Next, the control of the state information receiving unit 15 of the elevator 2A will be described with reference to the flowchart of fig. 7 and the schematic diagram of fig. 8. Fig. 8 shows a situation in which elevators 1A and 3A cannot use the public line network 5, and in which elevator 2A receives status information from elevators 1A and 3A.
In step S401 of fig. 7, the state information receiving unit 15 of the elevator 2A detects the presence or absence of a communication from the mobile communication terminal 6 located in the proximity of the elevator 2A, that is, in the short-range wireless communication area of the state information receiving unit 15, and the process proceeds to step S402.
In step S402, the state information receiving unit 15 checks whether or not the detected portable communication terminal 6 stores the state information of the other elevator 1A, 3A, and if the state information is stored, it receives the state information and proceeds to step S403.
In step S403, the state information receiving unit 15 reads the position information of the elevators 1A and 3A from the position information of the state information records D1 and D3 of the elevators 1A and 3A, and compares the position information with the position information of the elevator 2A.
As shown in fig. 8, based on the position information of the elevators 1A, 2A, and 3A, when the position of the elevator 1A is within a circular area (for example, a radius of 5Km) of a radius R that is a predetermined range centering on the position of the elevator 2A (yes), the state information receiving unit 15 proceeds to step S404 to store the state information of the elevator 1A in the state information accumulating unit 13 of the elevator 2A, and update the information of the state information recording unit D in the state information accumulating unit 13. Fig. 9 shows the information of the updated state information recording unit D in the state information storage unit 13 of the elevator 2A. As shown in fig. 9, the state information storage unit 13 of the elevator 2A is added with a state information record D1 of the elevator 1A in addition to the state information record D2 of the elevator 2A.
On the other hand, when the position of the elevator 3A is outside the circular area centered on the position of the elevator 2A (no), the state information receiving unit 15 returns to the initial state without storing the state information of the elevator 3A in the state information accumulating unit 13 of the elevator 2A. That is, when the elevators 1A and 3A are located within the predetermined range in the elevator 2A, the state information of the elevators 1A and 3A is stored in the state information storage unit 13 of the elevator 2A.
Since the public network 5 can be used in the area where the elevator 2A is located, the control of steps S201 to S206 of the flowchart shown in fig. 5 is performed. As a result, the state information of the elevator 1A is transmitted to the monitoring center 4 via the monitoring communication unit 12 of the elevator 2A. The monitoring center 4 determines that a maintenance man needs to be dispatched to the elevator 1A based on the state information of the elevator 1A, and requests the maintenance man to the elevator maintenance management company from the monitoring center 4.
In this way, when the state information of the elevator 1A that cannot utilize the public line network 5 is transmitted to the monitoring center 4 via the elevator 2A that can utilize the public line network 5, only the state information of the elevator 1A located near the elevator 2A is transmitted to the monitoring center 4, and therefore, the monitoring center 4 can collectively determine the elevator state information located within a predetermined range, and can efficiently dispatch a serviceman to the elevator 1A where an abnormality occurs or passengers are trapped. That is, when the elevator 2A receives the state information from the other elevators 1A and 3A, the accumulation of the state information of the elevator 3A located at a position far from the elevator 2A is restricted, and therefore the monitoring center 4 can efficiently collect the state information.
Further, even when the mobile communication terminal 6 moves to the vicinity of the plurality of elevators 1A, 2A, 3A, accumulation of the state information of the elevators 1A, 2A, 3A outside the predetermined range is restricted, and therefore, diffusion of the state information of the elevators 1A, 2A, 3A can be suppressed. As a result, a serviceman can be dispatched according to the predetermined range, and the elevator abnormality can be quickly dealt with. Further, even when transmission to the monitoring center 4 is not possible due to a failure of the communication device of the monitoring communication unit 12 or the like, the status information can be transmitted to the monitoring center 4.
Next, embodiment 2 will be described with reference to fig. 10 to 13. In embodiment 1, accumulation of status information is restricted based on the position information of the elevators 1A, 2A, 3A, but in embodiment 2, accumulation of status information is restricted based on the group IDs of the elevators 1A, 2A, 3A.
The remote monitoring system 100 according to embodiment 2 has the same configuration as the remote monitoring system 100 according to embodiment 1, and since some control procedures are different, different control procedures will be described.
As shown in fig. 13, in embodiment 2, a "group ID" is present in the entry of the status information record D2. The group ID is an ID for classifying the elevators 1A, 2A, and 3A into a predetermined group, and for example, the group ID for which the serviceman a is responsible for elevator maintenance is classified into "AAAA", and the group ID for which the serviceman B is responsible for elevator maintenance is classified into "BBBB". In fig. 13, the elevator 2A is shown to be classified as group ID "AAAA".
In the flowchart of fig. 10, steps S501, S502, and S504 are the same as steps S401, S402, and S404 of fig. 7. Then, in step S503 of fig. 10, the state information receiving unit 15 reads the group ID of the elevator 1A or 3A, and compares the group ID with the group ID of the elevator 2A.
As shown in fig. 11, if the group ID "AAAA" of the elevator 2A and the group ID "AAAA" of the elevator 1A are the same group ID based on the group IDs of the elevators 1A, 2A, and 3A (yes), the state information receiving unit 15 proceeds to step S504 to store the state information of the elevator 1A in the state information storage unit 13 of the elevator 2A, and update the information of the state information recording unit D in the state information storage unit 13. Fig. 13 shows the information of the state information recording unit D updated in the state information accumulating unit 13 of the elevator 2A. As shown in fig. 13, the state information storage unit 13 of the elevator 2A is added with a state information record D1 of the elevator 1A in addition to the state information record D2 of the elevator 2A.
On the other hand, when the group ID "BBBB" of the elevator 3A is different from the group ID "AAAA" of the elevator 2A (no), the state information receiving unit 15 does not store the state information of the elevator 3A in the state information storage unit 13 of the elevator 2A.
In this way, in embodiment 2, by assigning a group ID to each of the elevators 1A, 2A, 3A, it is possible to individually specify the elevators 1A, 2A, 3A that are permitted to accumulate the status information of the elevators 1A, 2A, 3A. Therefore, the state information of the elevators 1A, 2A, 3A in charge of the serviceman can be efficiently collected. Further, by classifying the group ID according to the elevator type, it is possible to collect the state information of the specific elevators 1A, 2A, and 3A.
