  Hereinafter, embodiments will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram showing a configuration of an elevator remote monitoring system according to the first embodiment.

  An elevator 11 to be monitored is connected to a monitoring center 13 via a communication network 12. It is assumed that the elevator 11 is installed in a country different from the monitoring center 13. For example, it is assumed that the monitoring center 13 is in Japan and the elevator 11 is installed in a country other than Japan. That is, the monitoring center 13 remotely monitors the operation state of the elevator 11 existing in another country through the communication network 12.

  In the example of FIG. 1, only one elevator 11 is shown, but actually, a large number of elevators 11 installed in various places (in various parts of the world) for each country are monitored via the communication network 12. It is connected to the center 13. The monitoring center 13 displays various information sent from these elevators 11 on a monitoring screen, and responds by, for example, dispatching maintenance personnel to the site when any abnormality is detected.

  The communication network 12 includes a public line network. In addition to the monitoring center 13, an NTP (Network Time Protocol) server 14 is connected to the communication network 12. The NTP server 14 manages the local time (current time in the area where the elevator 11 is installed).

  The elevator 11 is provided with an elevator control device 21, a remote monitoring device 22, and a communication device 23. Normally, the remote monitoring device 22 is provided with a communication function (communication device 23), but this system is characterized by a configuration in which the remote monitoring device 22 and the communication device 23 are separated. Since the remote monitoring device 22 and the communication device 23 are separated, the remote monitoring device 22 does not have a communication function.

  The elevator control device 21 performs operation control of the entire elevator including, for example, speed control of a car, door opening / closing control, control corresponding to various operation buttons, and the like.

  The remote monitoring device 22 is a monitoring terminal for operation monitoring. The remote monitoring device 22 is connected to the elevator control device 21 and monitors the operation state of the elevator 11. In the present embodiment, the remote monitoring device 22 includes a country selection switch 24, a monitoring item table 25, a monitoring unit 26, and a time acquisition unit 27.

  The country selection switch 24 is a switch for selecting an arbitrary country from a plurality of countries prepared in advance. The monitoring item table 25 stores a plurality of monitoring items predetermined in each country (see FIG. 2). The monitoring unit 26 determines the country in which the elevator 11 is installed (hereinafter referred to as an installation country) from the state of the country selection switch 24, refers to the monitoring item table 25, and relates to each monitoring item corresponding to the installation country. Information is read from the elevator control device 21.

  The time acquisition unit 27 acquires the local time from the communication device 23. The monitoring unit 26 attaches the local time obtained by the time acquisition unit 27 to the communication device 23 with information related to each monitoring item.

  The communication device 23 is connected to the remote monitoring device 22. The communication device 23 sends information regarding each monitoring item read by the remote monitoring device 22 to the monitoring center 13 via the communication network 12 according to the communication standard of the country where the elevator 11 is installed. In addition, the communication device 23 includes a time acquisition unit 28 and periodically accesses the NTP server 14 on the communication network 12 to acquire accurate local time.

  In the configuration of FIG. 1, if the elevator control device 21 and the remote monitoring device 22 are integrated, for example, if the elevator control device 21 fails due to some abnormality, the monitoring function of the remote monitoring device 22 does not work and an error occurs. Information cannot be issued. For this reason, in this system, the elevator control device 21 and the remote monitoring device 22 are provided independently.

  Since the communication standards differ depending on the country where the elevator 11 is installed, if the remote monitoring device 22 and the communication device 23 are integrated, the remote monitoring device 22 cannot be used in other countries. For this reason, in this system, the remote monitoring device 22 and the communication device 23 are provided independently.

  Here, although the communication apparatus 23 uses the thing suitable for the country in which the elevator 11 is installed, the remote monitoring apparatus 22 is commonly used in each country. In this case, since the monitoring items differ depending on the country, the remote monitoring device 22 has a configuration in which the monitoring items can be arbitrarily changed for each country by operating the country selection switch 24.

  FIG. 2 is a diagram illustrating an example of the monitoring item table 25.

  Elevator monitoring items are not necessarily common in each country, and may vary from country to country. In the example of FIG. 2, “emergency call button pressed state”, “operation information: error log”, “operation information: operation log”, and the like are set as monitoring items for country A. In addition, “operation information: error log”, “operation information: operation log”, and the like are set as monitoring items for country B.

  “Emergency call button pressed state” is an item for monitoring the pressed state of an emergency call button 34 installed in a car 31 described later. In Japan, this monitoring item is mandatory, but in other countries it may not be necessary.

  The “operation information: error log” is an item for monitoring errors that occur during operation of the elevator 11. Actually, there are various monitoring items related to errors in each country, but the details are classified here and are omitted here.

  “Operation information: operation log” is an item for monitoring the operation state of the elevator 11. Actually, there are various items related to operation depending on the country, but the details will be omitted here because they are classified as confidential matters.

  For example, maintenance information including the number of times the elevator 11 is started, door opening / closing time, travel distance, and the like may be added as one of the monitoring items and sent to the monitoring center 13.

  FIG. 3 is a diagram showing an example of an elevator car.

  The elevator 11 includes a car 31 as shown in FIG. A car door 32 is attached to the front of the car 31 so as to be freely opened and closed. Next to the car door 32, an operation panel 33, an emergency call button 34, a microphone 35, a speaker 36, a display 37, and the like are installed.

  The operation panel 33 is provided with various operation buttons including a plurality of floor buttons 33a, a door opening button 33b, a door closing button 33c, and the like. The emergency call button 34 is an operation button for contacting the outside in an emergency. The outside is the monitoring center 13 shown in FIG. That is, when the pressing state of the emergency call button 34 is included in the monitoring item, when the emergency call button 34 is pressed, the telephone line between the car 31 and the monitoring center 13 is connected, and the passenger A telephone call can be made with an operator of the monitoring center 15 through a microphone 35 and a speaker 36 installed near the call button 34. The display device 37 is composed of, for example, a small LCD (Liquid Crystal Display), and displays a driving state such as a current position and a driving direction of the car 31.

  Next, the operation of the first embodiment will be described.

  FIG. 4 is a flowchart showing the operation of the elevator remote monitoring system according to the first embodiment.

  Assume that the elevator 11 installed in a country different from the monitoring center 13 is activated. At the site, the maintenance staff selects a local country by operating a country selection switch 24 provided in the remote monitoring device 22 and then turns on the power of the remote monitoring device 22. At this time, it is assumed that the elevator 11 is provided with a communication device 23 conforming to the communication standard of the country.

  When the power of the remote monitoring device 22 is turned on (Yes in step S11), the monitoring unit 26 confirms the state of the country selection switch 24 (step S12) and determines the country where the elevator 11 is installed (step S13). And the monitoring part 26 sets each monitoring item corresponding to the installation country with reference to the monitoring item table 25 (step S14).

  For example, if country A is selected by the country selection switch 24, the monitoring unit 26 sets each monitoring item corresponding to country A with reference to the monitoring item table 25 shown in FIG. Specifically, for example, a flag is set for each monitoring item in country A so that each monitoring item for which the flag is set during operation of the elevator 11 can be monitored.

  The monitoring unit 26 also synchronizes the time acquisition unit 27 of the remote monitoring device 22 and the time acquisition unit 28 of the communication device 23 (NTP synchronization), acquires the local time from the communication device 23, and sets it in the time acquisition unit 27. (Step S15).

  In this way, when each monitoring item corresponding to the country where the elevator 11 is installed and the local time are set, the monitoring for each monitoring item is continuously performed during the operation of the elevator 11, and these monitoring items are monitored. The information regarding is sent to the monitoring center 13 at a predetermined timing.

  Specifically, first, the monitoring unit 26 confirms each monitoring item corresponding to the country where the elevator 11 is installed, and reads information regarding these monitoring items from the elevator control device 21 (step S16). The monitoring unit 26 attaches the local time acquired by the time acquisition unit 27 to the information and gives the information to the communication device 23 (step S17). The communication device 23 confirms the state of the communication network 12, and transmits each information received from the remote monitoring device 22 to the monitoring center 13 via the communication network 12 when communication is possible (step S18). The same processing is continuously performed for all the monitoring items, and information regarding these monitoring items is sent to the monitoring center 13 through the communication device 23 (step S19).

  Here, since the local time is attached to the information (monitoring information) regarding each monitoring item, even if there is a time difference between the country where the elevator 11 is installed and the country where the monitoring center 13 is installed, the monitoring center On the 13th side, each monitoring information can be recognized based on the local time. For example, there is a time difference of +12 hours from the local site, and even if some monitoring information enters the monitoring center 13 at 21:00, the time information added to the monitoring information occurred at 9:00 on the site Can be recognized.

  Although it is conceivable to add the local time when sending the monitoring information by the communication device 23, depending on the communication state of the communication network 12, the monitoring information may not be sent immediately. Therefore, in this embodiment, when monitoring information is read from the elevator control device 21 on the remote monitoring device 22 side, the local time is added. In this case, since the remote monitoring device 22 cannot access the NTP server 14 (since the remote monitoring device 22 does not have a communication function), the accurate local time is acquired in synchronization with the NTP of the communication device 23.

  As described above, according to the first embodiment, the remote monitoring device 22 and the communication device 23 are separated, and the remote monitoring device 22 is provided with a function that can arbitrarily set the monitoring items of each country. Therefore, it is possible to monitor each monitoring item corresponding to the country where the elevator 11 is installed. In this case, the communication device 23 is adapted to the communication standard of the country where the elevator 11 is installed, but the remote monitoring device 22 can be commonly used in each country without requiring software improvement.

(Second Embodiment)
Next, a second embodiment will be described.

  In the first embodiment, the country where the elevator 11 is installed is determined from the state of the country selection switch 24 when the power is turned on. In the second embodiment, the country where the elevator 11 is installed is determined without using the country selection switch 24. It is configured to do.

  FIG. 5 is a diagram showing a configuration of an elevator remote monitoring system according to the second embodiment. In addition, the same code | symbol is attached | subjected to the same part as the structure of FIG. 1 in the said 1st Embodiment, and the description shall be abbreviate | omitted.

  In the second embodiment, the elevator control device 21 is provided with a storage unit 29 in which data relating to the country where the elevator 11 is installed (referred to as country data) is stored in advance. The remote monitoring device 22 does not have the country selection switch 24 shown in FIG. 1, but has a function of reading country data from the storage unit 29 of the elevator control device 21 when the power is turned on.

  In such a configuration, when the power of the remote monitoring device 22 is turned on, the monitoring unit 26 reads the country data from the storage unit 29 of the elevator control device 21, and the country where the elevator 11 is installed based on the country data. Judging.

  The subsequent steps are the same as those in the first embodiment. That is, the monitoring unit 26 refers to the monitoring item table 25 to set each monitoring item corresponding to the country in which the elevator 11 is installed, and also synchronizes the NTP between the communication device 23 and the remote monitoring device 22. Make the time available. Then, during the operation of the elevator 11, the monitoring unit 26 reads information related to each monitoring item from the elevator control device 21, gives the local time to the communication device 23. The communication device 23 sends these pieces of information to the monitoring center 13 when the communication network 12 is in a communicable state.

  As described above, according to the second embodiment, each monitoring item corresponding to the country where the elevator 11 is installed based on the country data stored in the storage unit 29 of the elevator control device 21 without requiring the country selection switch 24. Can be set automatically.

(Third embodiment)
Next, a third embodiment will be described.

  In the third embodiment, in the configuration in which the remote monitoring device and the communication device are separated, the communication device is provided with a function capable of arbitrarily setting the priority order of each monitoring item in accordance with the country where the elevator is installed. And

  FIG. 6 is a diagram illustrating a configuration of an elevator remote monitoring system according to the third embodiment. In this example, a configuration in the case of remotely monitoring the operation state of two elevators 50a and 50b (No. A and No. B) is shown.

  The elevators 50a and 50b are assumed to be installed in one building. Further, it is assumed that the elevators 50a and 50b are installed in a country different from the monitoring center 71. For example, it is assumed that the monitoring center 71 is in Japan and the elevators 50a and 50b are installed in countries other than Japan.

  The elevator 50a of the No. A machine is provided with an elevator control device 51a and a remote monitoring device 52a. The elevator control device 51a includes a control unit 53a. The control unit 53a performs operation control of the elevator 50a including, for example, speed control of the car 31 of the car A, door opening / closing control, control corresponding to various operation buttons, and the like. The remote monitoring device 52a is connected to the elevator control device 51a, and has a monitoring unit 54a that monitors the operating state of the elevator 50a. The monitoring unit 54a reads information regarding each monitoring item set in the elevator 50a from the control unit 53a.

  The same applies to the elevator 50b of Unit B, and an elevator control device 51b and a remote monitoring device 52b are provided. The elevator control device 51b has a control unit 53b. The control unit 53b performs operation control of the elevator 50b including, for example, speed control of the car 31 of the car B, door opening / closing control, control corresponding to various operation buttons, and the like. The remote monitoring device 52a is connected to the elevator control device 51b and includes a monitoring unit 54b that monitors the operation state of the elevator 50b. The monitoring part 54b reads the information regarding each monitoring item set to the elevator 50b from the control part 53a.

  The remote monitoring devices 52a and 52b are assumed to have a function capable of arbitrarily setting the monitoring items of each country as in the first or second embodiment. That is, the remote monitoring devices 52a and 52b are provided with the monitoring item table 25 shown in FIG. 2, and each monitoring item corresponding to the country where the elevators 50a and 50b are installed is set based on switch operation or country data. . Furthermore, it is assumed that the remote monitoring devices 52a and 52b also have a function of acquiring the local time from the communication device 60 and adding the local time to information on each monitoring item.

  The communication device 60 is used in common with the Units A and B, and the information regarding each monitoring item read individually by the remote monitoring devices 52a and 52b is sent to the monitoring center 71 according to the communication standard of the country where the elevators 50a and 50b are installed. Has the function to send. Further, as in the first and second embodiments, the communication device 60 has a function of periodically accessing the NTP server 14 on the communication network 12 shown in FIG. 1 to obtain accurate local time. It shall be.

  Here, in the present embodiment, the communication device 60 includes a priority order table 61, a priority determination unit 62, a storage unit 63, and a communication unit 64.

  The priority order table 61 stores the priority order for each monitoring item (see FIG. 7). The priority determination unit 62 refers to the priority order table 61 and determines the priority of information regarding each monitoring item read by the monitoring units 54a and 54b. The storage unit 63 is used to temporarily hold information regarding each monitoring item. The communication unit 64 has a communication standard of the country where the elevators 50 a and 50 b are installed, and monitors the information related to each monitoring item with the local time according to the priority determined by the priority determination unit 62 via the communication network 70. Send to center 71.

  The monitoring center 71 is provided with a communication unit 72. The monitoring center 71 receives information on each monitoring item sent from the elevators 50a and 50b existing in other countries by the communication unit 72, and displays such information on the monitoring screen to detect any abnormality. In such cases, send maintenance personnel to the site.

  Moreover, even if there is a time difference between the country in which the elevators 50a and 50b are installed and the country in which the monitoring center 71 is installed by sending the information (monitoring information) about each monitoring item with the local time to the monitoring center 71, On the monitoring center 71 side, each monitoring information can be recognized based on the local time.

  FIG. 7 is a diagram showing an example of the priority order table 61.

  The priority order table 61 stores priority orders for the monitoring items set in the elevators 50a and 50b. When there are the same monitoring items in Unit A and Unit B, the priority order is stored including which unit's monitoring item is prioritized. In the example of FIG. 7, the “emergency call button pressed state” of Unit A, the “emergency call button pressed state” of Unit B, the “operation information: error log” of Unit A, the “operation information: operation log” of Unit B ... The priority order for each monitoring item is stored in this order.

  The “emergency call button pressed state”, “operation information: error log”, and “operation information: operation log” are as described in the first embodiment. Actually, there are more detailed monitoring items, but the details are classified here and are omitted here.

  Next, the operation of the third embodiment will be described.

  FIG. 8 is a flowchart showing the operation of the elevator remote monitoring system according to the third embodiment.

  During operation of the elevator 50a of the No. A machine, information related to each monitoring item of the No. A machine is read from the control part 53a of the elevator control unit 51a by the monitoring unit 54a provided in the remote monitoring device 52a. Similarly, during operation of the elevator 50b of the No. B machine, information related to each monitoring item of the No. B machine is read from the control part 53b of the elevator control apparatus 51b by the monitoring unit 54b provided in the remote monitoring device 52b.

  Each monitoring item includes “emergency call button pressed state”, “operation information: error log”, “operation information: operation log”, and the like. Information regarding these monitoring items (monitoring information) is given to the communication device 60 in the order read by the monitoring units 54a and 54b.

  As illustrated in FIG. 8, when the priority determination unit 62 provided in the communication device 60 acquires each piece of monitoring information from the monitoring units 54a and 54b (Yes in step S21), each priority information is referred to the priority order table 61. The priority of the monitoring information is determined (step S22).

  On the other hand, the communication unit 64 checks the communication state of the communication network 70 (step S23). And if it is in a communicable state (Yes of step S24), the communication part 64 will transmit each monitoring information to the monitoring center 71 according to the priority determined by the priority determination part 62 (step S25).

  On the other hand, if the communication is disabled, the communication unit 64 holds the monitoring information in the storage unit 63 (step S26), and when the communication is enabled, the communication unit 64 stores the monitoring information from the storage unit 63. The data is read and transmitted to the monitoring center 71 (steps S22 to S25).

  For example, it is assumed that monitoring information indicating that the emergency call button of Unit A has been pressed and monitoring information indicating that some error has occurred during operation of the car 31 of Unit A is provided to the communication device 60.

  In such a case, as shown in FIG. 7, “Emergency call button pressed state” is set higher in priority order than “operation information: error log”. The telephone line with the monitoring center 71 is connected via the communication network 70 with priority given to this. At this time, the communication device 60 holds the operation information in the storage unit 63 and transmits the operation information to the monitoring center 71 as soon as the emergency call is over.

  In Japan, the monitoring item “Emergency call button pressed” is indispensable, but it may not be necessary in other countries. Deleting or changing the monitoring items in the priority order table 61 can be easily performed from the monitoring center 71 by remote operation. The same applies when the number of units is increased or decreased, and the priority order table 61 can be changed according to the current number of units by remote control from the monitoring center 71.

  As described above, according to the third embodiment, the remote monitoring devices 52a and 52b and the communication device 60 are separated, and the communication device 60 has a function capable of arbitrarily setting the priority order of each monitoring item. Information relating to monitoring items can be given priority and sent to the monitoring center 71.

  Usually, when the elevator to be monitored is in the same Japan as the monitoring center, the remote monitoring device used for the elevator has a communication function, and control of monitoring items and communication control are performed with one software. Yes. For this reason, when using a remote monitoring device in an elevator installed in a country other than Japan, it is necessary to redesign the monitoring item control and communication control software according to that country. Cannot be expanded. On the other hand, in this system, since the remote monitoring device and the communication device are separated, the communication device that matches the communication standard of the country is used, but the priority of each monitoring item is used for the remote monitoring device. It can be used in all countries just by changing the order.

  According to at least one embodiment described above, there is provided an elevator remote monitoring system, a remote monitoring device, and a communication device capable of remotely monitoring the operation state of an elevator installed in each country without requiring troublesome work. Can be provided.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
