  Hereinafter, prior to the description of a remote monitoring system for a lifting device according to the present invention, a lifting device as a premise will be described. The lifting device includes an elevator, an escalator, and the like. In the remote monitoring system of the present embodiment, an elevator will be described as an example of a lifting device.

  As shown in FIG. 1, the elevator includes an operation unit 20 having a car, a hoistway, and the like, and a signal output unit 21 that outputs a signal related to the operation unit 20. The signal output unit 21 of the present embodiment includes a control microcomputer 210 that outputs a code indicating the status of the elevator 2, a two-way talker 211 such as an interphone capable of making a voice call with a user in the car, a camera that photographs the inside of the car, and the like. , A sound collector 213 such as a microphone that outputs sound information around the car and the counterweight, a detection sensor 214 that detects a user and the like in the car, and a power supply monitoring device that outputs information on the power supply of the elevator 2 215 etc. Further, the signal output unit 21 outputs a signal corresponding to the status of the elevator 2. An abnormal situation of the elevator 2 in the present embodiment is a failure of a car door or a landing door, a service life of a car lighting, and the like. The control microcomputer 210 of the present embodiment transmits the code assigned to each condition of the elevator 2 to the remote monitoring unit 3.

  Next, an outline of the remote monitoring system 1 will be described. The remote monitoring system 1 includes a remote monitoring unit 3 that monitors the elevator 2 and a plurality of technician mobile terminals 4 (hereinafter, simply referred to as mobile terminals 4) capable of receiving signals from the remote monitoring unit 3 by wireless communication. . Although two mobile terminals 4 are shown in FIG. 1, there are actually three or more mobile terminals 4. Further, the remote monitoring system 1 of the present embodiment includes a server 5 communicably connected to the remote monitoring unit 3 by wire.

  The remote monitoring unit 3 has a CPU (Central Processing Unit) 30 for inputting and outputting signals, and a storage unit 31 for storing information necessary for inputting and outputting signals. When the signal output unit 21 outputs a signal indicating an abnormal situation of the elevator 2, the remote monitoring unit 3 determines a predetermined mobile terminal 4 (FIG. 1 to the portable terminal 4A). The remote monitoring unit 3 of the present embodiment outputs an alarm signal and outputs information on the status of the elevator 2 to the mobile terminal 4.

  The remote monitoring unit 3 is connected to the signal output unit 21 (the control microcomputer 210, the two-way talker 211, the imaging device 212, the sound collector 213, the detection sensor 214, and the power monitoring device 215) by wire, for example, P2P (Peer to Peer). ). Further, the remote monitoring unit 3 is connected to the mobile terminal 4 by a connection system R1. The connection system R1 is, for example, a connection system including a modem, a telephone line, a base station, and wireless communication. The wireless communication here is, for example, mobile phone communication. As described above, in the remote system 1 of the present embodiment, the remote monitoring unit 3 and the portable terminal 4 perform communication via the telephone line. Further, the remote monitoring unit 3 is wiredly connected to the server 5 via a connection system R2 so as to be communicable. The connection system R2 is, for example, a connection system including two modems and a telephone line. In the remote monitoring system 1 of the present embodiment, a part of the connection systems R1 and R2 (connection from the modem to the telephone line) is common.

  The storage unit 31 stores predetermined mobile terminal information 310 regarding a predetermined mobile terminal 4 (mobile terminal 4A) and urgency determination data 311.

  The predetermined portable terminal information 310 in the present embodiment is rewritable. Further, the predetermined mobile terminal information 310 in the present embodiment is information regarding one mobile terminal 4. Specifically, the predetermined mobile terminal information 310 is the telephone number of the predetermined mobile terminal 4A (the mobile terminal 4 that is the first alert destination).

  The urgency determination data 311 is data that coincides with a signal indicating an abnormal and urgent situation of the elevator 2 among the signals output from the signal output unit 21. Specifically, the urgency determination data 311 is, for example, a code that matches the code output from the control microcomputer 210 when the elevator 2 is in an abnormal state and the situation becomes urgent. Here, the emergency situation of the elevator 2 is, for example, confinement of the user in the car due to the inability to open or close the car door or the landing door, ignition from the motor or the like, brake failure, occurrence of an earthquake, and the like.

  When receiving a signal from the signal output unit 21 and determining that the signal is a signal indicating an abnormal situation of the elevator 2, the CPU 30 of the present embodiment determines the predetermined portable terminal information 310 stored in the storage unit 31. To the portable terminal 4 to output an alarm signal and information on the status of the elevator 2. Further, CPU 30 determines whether or not portable terminal 4 cannot communicate.

  The CPU 30 of the present embodiment determines, for example, whether or not information can be acquired from the mobile terminal 4 and whether or not communication with the mobile terminal 4 is possible based on the connection sensitivity of the base station of the connection system R1. When communication with the portable terminal 4 is impossible, the CPU 30 outputs a communication impossible signal to the server 5. At this time, the CPU 30 of the present embodiment determines the urgency of the situation of the elevator 2, outputs an emergency signal together with a communication disable signal to the server 5 when there is emergency, and sends a communication disable signal to the server 5 when there is no emergency. And outputs a normal signal.

  Note that the CPU 30 of the present embodiment determines the urgency of the status of the elevator 2 based on whether or not the code transmitted from the control microcomputer 210 matches the urgent code (urgency determination data 311). . After that, the CPU 30 receives the information from the server 5 and rewrites the information of the mobile terminal 4 of the predetermined mobile terminal information 310, and sends the alert signal and the elevator 2 information to the next candidate mobile terminal 4 (mobile terminal 4B in FIG. 1). Prints out information about the situation.

  The mobile terminal 4 includes a CPU 40 that executes a program, a storage unit 41 that stores the program executed by the CPU 40, a display unit, a speaker, and a microphone (not shown). The mobile terminal 4 is, for example, a PDA (Personal Digital Assistant). The mobile terminal 4 of the present embodiment is operated hands-free by a technician using voices or the like, for example. Since the mobile terminal 4 is connected to the base station of the connection system R1 by wireless communication, the mobile terminal 4 can receive an alarm signal from the remote monitoring unit 3 by wireless communication. Further, the mobile terminal 4 is also connected to the server 5 by a connection system R3. The connection system R3 is, for example, a connection system including a router, the Internet, and a modem.

  The mobile terminal 4 of the present embodiment can transmit a signal to the remote monitoring unit 3 via the connection system R1, and thereby, for example, can directly rewrite data stored in the storage unit 31. Further, the mobile terminal 4 of the present embodiment can transmit a signal to the elevator 2 via the connection system R1 and the remote monitoring unit 3, and thereby, for example, can directly operate the control microcomputer 210. In addition, since the mobile terminal 4 is connected to the server 5 via the connection system R3, the mobile terminal 4 notifies the server that the alert signal can be received, or the server 5 notifies the mobile terminal 4 to the mobile terminal 4. It is possible to confirm whether or not the alert signal can be received. When the server 5 recognizes that the mobile terminal 4 cannot receive the alarm signal, the server 5 can switch in advance so that the next candidate mobile terminal 4 receives the alarm signal. Further, the server 5 can notify each of the mobile terminals 4 of the switching of the alarm signal receiving destination.

  The storage unit 41 of the present embodiment stores a remote monitoring application 410 (second execution file 410) which is a program executed by the CPU 40.

  When receiving the alarm signal from the remote monitoring unit 3, the CPU 40 of the present embodiment executes the remote monitoring application 410 stored in the storage unit 41 and causes the mobile terminal 4 to display information on the status of the elevator 2. . That is, the CPU 40 causes the mobile terminal 4 to display information on the status of the elevator 2 by executing the remote monitoring application 410.

  Specifically, when the remote monitoring application 410 receives information on the car door of the elevator 2 from the control microcomputer 210, an illustration of the car door and the like can be displayed on the display unit of the mobile terminal 4. In addition, the remote monitoring application 410 can display the video output from the photographing device 212 on the display unit of the mobile terminal 4 and can output the sound output from the sound collector 213 from the speaker of the mobile terminal 4. . Further, the remote monitoring application 410 allows the technician to make a two-way call with the two-way talker 211 using the speaker and the microphone of the mobile terminal 4.

  The server 5 includes a CPU 50 that executes a program, and a storage unit 51 that stores the program executed by the CPU 50. The server 5 of the present embodiment is a cloud server.

  The storage unit 51 stores a notification notification destination determination application 510 which is a program executed by the CPU 50, and an emergency database 511 and a normal database 512 each including data used when executing the notification notification destination determination application 510. ing. The emergency database 511 is rewritable.

  When receiving an emergency signal and an emergency signal from the remote monitoring unit 3, the CPU 50 executes the alarm notification destination determination application 510 stored in the storage unit 51 and reads the next candidate mobile terminal 4 ( The information on the portable terminal 4B) is selected, and this information is transmitted to the remote monitoring unit 3. In the remote unit 3, the predetermined portable terminal information 310 is rewritten by the transmitted information. When a normal signal is received from the remote monitoring unit 3 together with the communication disable signal, the alert notification destination determination application 510 selects information on the next candidate mobile terminal 4 (mobile terminal 4B) from the normal database 512 and performs remote monitoring. This information is transmitted to the unit 3. In the remote unit 3, the information of the portable terminal 4A of the predetermined portable terminal information 310 is rewritten to the information of the portable terminal 4B based on the transmitted information.

  The emergency database 511 and the normal database 512 have information including connection priorities of the plurality of mobile terminals 4. The emergency database 511 of the present embodiment has information on a plurality of mobile terminals 4 and connection priorities in an emergency. The normal database 512 of the present embodiment has information on a plurality of mobile terminals 4 and connection priorities in a normal state. Having. As described above, since the remote monitoring unit 3 and the mobile terminal 4 of the present embodiment communicate via the connection system R1 including the telephone line, the mobile terminal included in the emergency database 511 and the normal database 512 in the present embodiment. The information of 4 is the telephone number of the mobile terminal 4. Specifically, the emergency database 511 and the normal database 512 each have a telephone number of the mobile terminal 4 and a connection priority.

  The emergency database 511 can be rewritten by the alert notification destination determination application 510. Specifically, the rewriting of the emergency database 511 is performed by setting the connection priority in the emergency database 511 based on the position information of each mobile terminal 4 that is constantly acquired by GPS (Global Positioning System). Are performed in ascending order of distance.

  Hereinafter, the flow of processing in the remote monitoring system 1 will be described with reference to the flowcharts of FIGS. 2 and 3.

  When an abnormality occurs in the elevator 2 (S01), the signal output unit 21 outputs a signal relating to the abnormality to the remote monitoring unit 3. When this signal is input, the remote monitoring unit 3 outputs an alarm signal and information on the status of the elevator 2 to a predetermined portable terminal 4A (S02).

  When the remote monitoring unit 3 is capable of communicating with the predetermined portable terminal 4A (No in S03), based on the information on the status of the elevator 2 output from the remote monitoring unit 3 to the predetermined portable terminal 4A, the predetermined Information on the status of the elevator 2 is displayed on the mobile terminal 4A (S15 in FIG. 3).

  If communication with the predetermined portable terminal 4A is not possible (Yes in S03), the remote monitoring unit 3 outputs a communication disable signal to the server 5 (S04), and determines the urgency of the status of the elevator 2 and determines An emergency signal or a normal signal is output to the server 5 according to the result (S05).

  When there is urgency in the status of the elevator 2 (Yes in S05), the notification notification destination determination application 510 receives the output emergency signal and, as described above, connects the elevator 2 and each mobile terminal 4 with each other. The connection priority in the emergency database 511 is rewritten based on the distance (S06). Next, the alert notification destination determination application 510 reads the telephone number of the next candidate portable terminal 4B from the emergency database 511 (S07), and transmits this telephone number to the remote monitoring unit 3 (S08).

  In response, the remote monitoring unit 3 rewrites the information of the predetermined portable terminal 4A to the information of the next candidate portable terminal 4B, and outputs an alarm signal and information on the status of the elevator 2 to the next candidate portable terminal 4B. (S09). If communication with the mobile terminal 4B is not possible (Yes in S10), a series of processing is performed again from S07. Therefore, the remote monitoring unit 3 of this embodiment uses the same emergency database 511 (the emergency database 511 in which the connection order is rewritten in S06 before the series of processing is repeated) while this series of processing is repeated. An alarm signal or the like is output to the candidate portable terminals 4 in the order of connection priority. When communication with the portable terminal 4B is possible (No in S10), alert information and information on information on the elevator 2 are transmitted to the portable terminal 4B, and information on the status of the elevator 2 is displayed on the portable terminal 4B. (S15).

  If the status of the elevator 2 is not urgent (No in S05), the alert notification destination determination application 510 receives the output normal signal and calls the next candidate mobile terminal 4B from the normal database 512. The number is read (S11), and the telephone number of the next candidate portable terminal 4B is output to the remote monitoring unit 3 (S12).

  In response, the remote monitoring unit 3 rewrites the information of the predetermined portable terminal 4A to the information of the next candidate portable terminal 4B, and outputs an alarm signal and information on the status of the elevator 2 to the next candidate portable terminal 4B. (S13). If communication with the portable terminal 4B is not possible (Yes in S14), a series of processing is performed again from S11. When communication with the mobile terminal 4B is possible (No in S14), the alarm information and the information on the information on the elevator 2 are transmitted to the mobile terminal 4B, and the information on the status of the elevator 2 is displayed on the mobile terminal 4B. (S15). In the example illustrated in FIG. 1, the mobile terminal 4 as the next candidate of the emergency database 511 and the normal database 512 is the same mobile terminal 4 (mobile terminal 4B), but may be different mobile terminals. .

  As described above, if the remote monitoring unit 3 cannot wirelessly communicate with the predetermined mobile terminal 4A, the remote monitoring unit 3 outputs an alarm signal to the mobile terminal 4B different from the predetermined mobile terminal 4A among the plurality of mobile terminals 4. I do. Therefore, according to the remote monitoring system 1, the technician can directly check the information on the status of the elevator 2 output from the remote monitoring unit 3 with the mobile terminal 4. Moreover, when the remote monitoring unit 3 and the portable terminal 4 to which the alarm signal is output cannot perform wireless communication, the remote monitoring unit 3 outputs the alarm signal to the portable terminal 4 different from the previous portable terminal 4. Thus, any one of the mobile terminals 4 can reliably receive the information. Thus, the remote monitoring system 1 can promptly respond to the elevator 2 to which the alarm signal has been output.

  In the remote monitoring system 1, since the server 5 has the emergency database 511 and the normal database 512, the remote monitoring unit 3 and the portable terminal 4 do not need to have these databases. Thereby, the memory capacity of the remote monitoring unit 3 and the portable terminal 4 (the capacity of the storage unit 31 and the storage unit 41) is suppressed.

  Further, in the remote monitoring system 1, as in S05 to S14, the server 5 transmits the alarm signal based on the emergency database 511 and the normal database 512 when the server 5 receives the communication disable signal (that is, the mobile terminal 4) , And determines the next candidate portable terminal 4), and transmits the telephone number of the portable terminal 4 to the remote monitoring unit 3. As a result, the remote monitoring unit 3 outputs an alarm signal to the portable terminal 4, so that a technician can be quickly arranged.

  In the remote monitoring system 1, the monitoring unit 10 transmits information on the status of the elevator 2 to the mobile terminal 4 (S02, S09, S13), and the mobile terminal 4 displays this information by executing the remote monitoring application 410. (S15). Therefore, according to the remote monitoring system 1, the technician can visually confirm the information on the status of the elevator 2 on the mobile terminal 4, and thus can easily grasp the status of the elevator 2.

  According to the remote monitoring system 1, the hands-free operation of the mobile terminal 4 is possible, so that the technician can operate the mobile terminal 4 even in a situation where the hand cannot be released due to work or the like.

  It should be noted that the remote monitoring system 1 of the present invention is not limited to the above embodiment, and it is needless to say that various changes can be made without departing from the scope of the present invention. For example, the configuration of another embodiment can be added to the configuration of one embodiment, and a part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Further, a part of the configuration of an embodiment can be deleted.

  For example, in the monitoring system 1, instead of the storage unit 41 of the mobile terminal 4 having the remote monitoring application 410, as illustrated in FIG. 4, the storage unit 51 of the server 5 stores the remote monitoring application 513 (first execution file 513). In addition, the storage unit 41 of the mobile terminal 4 may include the browser 411. Even in this case, the status of the elevator 2 can be displayed on the portable terminal 4 by the browser 411 executing the remote monitoring application 513. As described above, since the server 5 has the remote monitoring application 513, the mobile terminal 4 does not need to have this application, and the memory capacity of the mobile terminal 4 (the capacity of the storage unit 41 and the like) can be suppressed.

  The remote monitoring unit 3 and the portable terminal 4 of the above embodiment are connected by a connection system R1 (for example, a connection system including a modem, a telephone line, and a base station). However, as shown in FIG. In addition, they may be connected by a connection system R4. The connection system R4 is a connection system including a modem, the Internet, a router, and wireless communication. This wireless communication is, for example, communication by a wireless LAN. In this case, since the mobile terminal 4 is connected to the remote monitoring unit 3 via the Internet, a plurality of mobile terminals 4 can communicate with the remote monitoring unit 3 at the same time. Further, since the mobile terminal 4 is connected to the remote monitoring unit 3 through both the connection systems R1 and R4, even if the mobile terminal 4 cannot communicate via the telephone line, it can communicate via the Internet. , Can communicate with the remote monitoring unit 3.

  When the remote monitoring unit 3 and the mobile terminal 4 communicate with each other via the Internet, the predetermined mobile terminal information 310 and the IP address of the mobile terminal 4 are required as information of the mobile terminal 4 included in the emergency database 511 and the normal database 512. It is.

  Although the remote monitoring unit 3 of the above embodiment has confirmed the communication status of the portable terminal 4, the portable terminal 4 may confirm its own communication status instead. This confirmation can be performed when the remote monitoring unit 3 and the portable terminal 4 are connected by both a telephone line and the Internet, as shown in FIG. When the remote monitoring unit 3 and the mobile terminal 4 cannot communicate with each other via the telephone line and can communicate with each other via the Internet, the mobile terminal 4 is connected to the mobile terminal 4 before the alert signal is output from the remote monitoring unit 3 to the mobile terminal 4. A signal to the effect that communication is not possible via the telephone line can be output to the server 5 via the Internet. Thereby, the server 5 switches the communication connection in advance so that the next candidate mobile terminal 4 receives the alert, and the server 5 issues the alert by switching the communication connection after the alert. The effect of preventing a reception delay beforehand can be achieved.

  In the remote monitoring system 1 of the above embodiment, the specific configuration of each connection system is not particularly limited as long as the mobile terminal 4 can receive the alarm signal from the remote monitoring unit 3 by wireless communication. For example, although the elevator 2 of the above embodiment is connected to the remote monitoring unit 3 by P2P, the elevator 2 may be connected to the Internet using a wired line or wireless communication instead. Further, although a modem is interposed between the remote monitoring unit 3 and the telephone line in the connection system R1 of the above embodiment, a DSU (Digital Service Unit) may be interposed instead of the modem.

  In the remote monitoring system 1 of the above embodiment, as shown in FIG. 1, a part of the connection systems R1 and R2 (the connection from the modem to the telephone line) is common, but this is not particularly limited. For example, when the remote monitoring unit 3 has a plurality of telephone lines (telephone numbers), the connection systems R1 and R2 may be independent connection systems in which neither part is common.

  In the remote monitoring and viewing system 1 of the above-described embodiment, the remote monitoring unit 3 determines the urgency of the status of the elevator 2, but instead of the remote monitoring unit 3, the mobile terminal 4 determines the urgency. Good. In this case, as shown in FIG. 4, each of the plurality of mobile terminals 4 has the urgency determination data 412.

  Specifically, in the remote monitoring system 1, when the remote monitoring unit 3 outputs an alarm signal and information on the status of the elevator 2 to a predetermined mobile terminal 4 (S02 in FIG. 2), the remote monitoring unit 3 communicates with the predetermined mobile terminal 4. If it is possible (No in S03 of FIG. 2), as shown in the flowchart of FIG. 5, the predetermined portable terminal 4 determines the urgency of the information on the status of the elevator 2 (S16). Specifically, the predetermined portable terminal 4 compares the received information on the status of the elevator 2 with the information indicating the status of the elevator with urgency (urgency determination data 412) to determine the urgency of the status of the elevator 2 Judge.

  When there is no urgency in the status of the elevator 2 (No in S16), information on the status of the elevator 2 is displayed on a predetermined portable terminal 4 (S17). If the situation of the elevator 2 is urgent (Yes in S16), the predetermined portable terminal 4 outputs an emergency signal to the server 5 via the Internet (S18). Upon receiving the emergency signal, the notification notification destination application 510 rewrites the connection priority in the emergency database 511 (S19). Next, the notification notification destination application 510 obtains information on the next candidate mobile terminal 4 as the next notification destination from the emergency database 511 (in the remote monitoring system 1 of the present embodiment, the telephone number of the next candidate mobile terminal 4). ) Is read (S20), and it is determined whether or not the telephone number of the next candidate mobile terminal 4 matches a predetermined mobile terminal 4 telephone number (S21).

  If they match (Yes in S21), a series of processes from S08 in FIG. 3 is performed. If they do not match (No in S21), the server 5 outputs to the predetermined portable terminal 4 information indicating that it is not a candidate (S22). Thereby, the technician who possesses the predetermined portable terminal 4 can confirm that he / she does not need to cope with the elevator 2 by checking the information of the portable terminal 4. Thereafter, a series of processing is performed from S12 in FIG. If communication with the predetermined mobile terminal 4 is not possible (No in S03 of FIG. 2), for example, the next candidate mobile terminal 4 is selected from the normal database, and communication with the next candidate mobile terminal 4 becomes possible. At this point, the portable terminal 4 determines the urgency of the status of the elevator 2 (S16), and thereafter executes a series of processes from S16. Thus, the portable terminal 4 can determine the urgency of the elevator 2. In this case, since the mobile terminal 4 has the urgency determination data 412, the remote monitoring unit 3 does not need to have the urgency determination data 412, and the memory capacity of the remote monitoring unit 3 (the capacity of the storage unit 31) is reduced. Can be

  If the server 5 and the mobile terminal 4 are connected by a telephone line in addition to the Internet, the mobile terminal 4 can output an emergency signal to the server 5 via the telephone line.

  In the remote monitoring system 1, after outputting the communication disable signal to the server 5 in S04, the emergency signal or the normal signal is output by determining the urgency of the status of the elevator 2 in S05. After the urgency of the second situation is determined first, an emergency signal may be output together with the communication disabled signal, or a normal signal may be output together with the communication disabled signal.

  In the remote monitoring system 1, as shown in FIG. 4, when there is urgency, the predetermined portable terminal 4 outputs an emergency signal to the server 5 via the Internet. An emergency signal may be output to the server 5 via the remote monitoring unit 3 (via the connection system R1, the modem, the Internet, and the modem). Note that, in addition to the mobile terminal 4, the server 5 may also have urgency determination data. Thereby, even when communication with the mobile terminal 4A is not possible (Yes in S03 of FIG. 2), the server 5 can determine the urgency, so that communication between the mobile terminal 4A and another mobile terminal 4 is performed. It is not necessary for the portable terminal 4 to judge the urgency.

  Although the notification notification destination determination application 510 of the server 5 of the above embodiment has determined the mobile terminal 4 to which the notification signal is transmitted, the remote monitoring unit 3 may determine this. In this case, the remote monitoring unit 3 has a database of connection priorities of the plurality of mobile terminals, and when it is determined that wireless communication with the predetermined mobile terminal 4A is impossible, the remote monitoring unit 3 differs from the predetermined mobile terminal 4A based on the database. The mobile terminal 4B (the mobile terminal 4B that transmits the alert signal) is determined. Specifically, as shown in FIG. 6, the storage unit 31 of the remote monitoring unit 3 includes an alert notification destination determination application 312, an emergency database 313, and a normal database 314 in addition to the predetermined mobile terminal information 310. .

  Even in this case, when the remote monitoring unit 3 and the portable terminal 4 to which the alarm signal is output cannot perform wireless communication, the remote monitoring unit 3 transmits the alarm signal based on the emergency database 511 and the normal database 512. Is determined (the next candidate mobile terminal 4B), and an alarm signal is transmitted. Therefore, even in this case, the arrangement of the engineer is not delayed. Further, since the remote monitoring unit 3 has the alert notification destination determination application 312, the emergency database 313, and the normal database 314, the server 5 does not need to have these applications and databases, and the capacity of the server 5 (storage unit) 51 capacity).

  Although the number of elevators 2 in the above embodiment is one, a plurality of elevators 2 may be provided. In this case, one remote monitoring unit 3 may monitor a plurality of elevators 2, or a plurality of remote monitoring units 3 may monitor a plurality of elevators 2 so that one remote monitoring unit 3 monitors one elevator 2. The elevator 2 may be monitored. When there are a plurality of elevators 2, each of the emergency database 511 and the normal database 512 has, for example, the identification number of each elevator 2 and the connection priority of each elevator 2.

  In the remote monitoring system 1 of the above embodiment, as shown in FIG. 2 and FIG. 3, when communication with the predetermined portable terminal 4A is not possible and the status of the elevator 2 is urgent, the emergency database 511 in S06. Is rewritten once, and a series of processes from S07 is repeated using the same database until the next candidate portable terminal 4 becomes communicable (until “No” in S10). However, in this case, after the emergency database 511 is once rewritten in S06, the emergency database 511 may be rewritten again while the series of processing from S07 is repeated. For example, when a certain period of time has elapsed while the series of processes from S07 is repeated, the emergency database 511 may be rewritten again. The emergency database 511 does not need to be rewritable.

  Although the storage unit 31 of the remote monitoring unit 3 of the above embodiment stores information of one mobile terminal 4A as the predetermined mobile terminal information 310, information of a plurality of mobile terminals 4 may be stored. . In this case, in S02 in FIG. 2, the alarm signal and the status signal are sequentially output to the plurality of mobile terminals 4 based on the information 310 stored in the storage unit 31. In this case, in S03 in FIG. 2, if communication with at least one mobile terminal 4 is possible, it may be determined that communication is possible in S03, or if communication with all mobile terminals 4 is possible. Only in S03, it may be determined that communication is possible. Furthermore, when it is possible to communicate with an arbitrary number or more of the mobile terminals 4, it may be determined that communication is possible in S03.

  The server 5 of the above-described embodiment has always acquired the position information of each portable terminal 4 by GPS, but may acquire it at any time when there is an urgency (in the case of Yes in S05).

  Although the server 5 in the above embodiment is a cloud server, the server may be an external server or a company server. Further, the number of the server 5 in the above embodiment is one, but a plurality may be provided.

  Although the storage unit 51 of the above embodiment stores a plurality of databases of the emergency database 511 and the normal database 512 as the databases used by the alert notification destination determination application 510, these databases are used instead of these two databases. One integrated database may be stored. Also, instead of these two databases, three or more databases may be stored.

  The server 5 of the above embodiment determines the urgency of the status of the elevator 2 and reads the information of the next candidate mobile terminal 4 from the different databases 511 and 512 according to the urgency. Instead, the information of the next candidate portable terminal 4 may be always read from a certain database.
