Description

  The present invention relates to a maintenance / inspection support system that supports maintenance / inspection work of an elevator.

  Maintenance and inspection work for elevators is often performed by maintenance personnel operating the control panel. In a conventional general elevator, a maintenance staff can perform a maintenance inspection work by operating a control panel installed in a machine room. However, in a machine room-less type elevator which has become mainstream in recent years, a control panel is installed in a hoistway, so that maintenance personnel cannot easily perform maintenance inspection work by operating the control panel.

  The control device 1 includes a storage unit 1 a for recording information, is connected to the line interface 5, and can communicate with the monitoring center 11 at a remote location via the line network 10 connected to the line interface 5. it can. The line network 10 can be a public line network such as an analog telephone line or an IP communication network for performing communication using the Internet protocol.

  A platform 40 of the elevator 30 is provided with a platform display device 3 for displaying the driving direction and current position of the elevator 30 and various information, and a platform call button not shown in FIG. A wireless terminal 4 that is a short-range wireless communication device is installed at a landing 40 on the reference floor. The hall display device 3, the wireless terminal 4, and the hall call button are connected to the control device 1.

  The maintenance portable terminal 20 can perform wireless communication with the wireless terminal 4, can operate the control device 1 by wireless communication, and can operate the elevator 30. A maintenance worker who performs maintenance and inspection work of the elevator 30 has the maintenance portable terminal 20, and the maintenance portable terminal 20 and the wireless terminal 4 perform wireless communication, thereby performing various maintenance using the maintenance portable terminal 20. Inspection work can be carried out. The maintenance mobile terminal 20 can acquire the position (latitude and longitude) of the maintenance mobile terminal 20 by receiving a signal (GPS signal) from the GPS satellite 13. Furthermore, the maintenance mobile terminal 20 can communicate and talk with various devices connected to the network 10 via the mobile phone base station 12 as a general mobile phone or smartphone.

  The monitoring center 11 can communicate with the elevator 30 and the maintenance portable terminal 20, can monitor the elevator 30, and can hold information regarding the elevator 30 and the maintenance portable terminal 20. For example, the monitoring center 11 has previously input the position (for example, latitude and longitude) of the elevator 30 that performs the maintenance inspection work and the scheduled maintenance inspection date and time, and the position of the maintenance portable terminal 20 (the latitude determined by the GPS signal) Longitude) can be acquired via the mobile phone base station 12 and the network 10.

  The elevator 30 may include at least one of the in-car display device 2a and the landing display device 3. Whether both the car display device 2a and the landing display device 3 are provided or only one of them is provided depends on the elevator 30 installed in the building. Hereinafter, an example in which the elevator 30 includes both the in-car display device 2a and the landing display device 3 will be described. The in-car display device 2a and the landing display device 3 display a message for guiding the operation of the elevator 30 during normal operation of the elevator 30 (when maintenance work is not performed).

  FIG. 2 is a diagram illustrating a configuration of the maintenance portable terminal 20 in the elevator maintenance inspection support system according to the present embodiment. The maintenance portable terminal 20 includes a wireless terminal communication unit 21, a mobile phone base station communication unit 22, a GPS reception unit 23, an atmospheric pressure sensor 24, a terminal position calculation unit 25, and a maintenance inspection application 26.

  The wireless terminal communication unit 21 performs short-range wireless communication with the wireless terminal 4 installed at the landing 40 according to a standard such as Wi-Fi or Bluetooth (registered trademark). The mobile phone base station communication unit 22 performs wide-area wireless communication with the mobile phone base station 12 according to a standard such as 3G or LTE. The GPS receiving unit 23 communicates with the GPS satellite 13 and receives a GPS signal. The atmospheric pressure sensor 24 detects the atmospheric pressure at the position of the maintenance portable terminal 20. The terminal position calculation unit 25 obtains the position of the maintenance portable terminal 20. The maintenance / inspection application 26 is software that executes various maintenance / inspection operations of the elevator 30.

  The terminal position calculator 25 can obtain the approximate position (latitude and longitude) of the maintenance portable terminal 20 with an accuracy of about 10 m using the GPS signal received by the GPS receiver 23.

  The wireless terminal communication unit 21 always transmits radio communication radio waves and performs wireless communication with the wireless terminal 4 within a range of about several tens of meters. The terminal position calculation unit 25 can obtain the distance between the maintenance portable terminal 20 and the wireless terminal 4 with an accuracy of several tens of centimeters from the electric field strength of radio waves of wireless communication between the wireless terminal communication unit 21 and the wireless terminal 4. The wireless terminal 4 may measure the electric field strength, and the control device 1 may determine the distance between the maintenance portable terminal 20 and the wireless terminal 4 from the electric field strength.

  Furthermore, the terminal position calculation unit 25 can obtain the altitude of the position of the maintenance portable terminal 20 from the atmospheric pressure value detected by the atmospheric pressure sensor 24 with an accuracy of about several tens of centimeters. The terminal position calculation unit 25 holds the altitude of the reference floor and the atmospheric pressure value (reference atmospheric pressure) at the reference floor, and the atmospheric pressure value detected by the atmospheric pressure sensor 24, the reference atmospheric pressure, and the altitude of the reference floor. Thus, the altitude of the position of the maintenance portable terminal 20 is obtained. Further, the terminal position calculation unit 25 obtains a difference between the altitude of the position of the maintenance portable terminal 20 and the altitude of the reference floor. The terminal position calculation unit 25 may calculate the relative altitude of the position of the maintenance portable terminal 20 with respect to the reference floor using the atmospheric pressure at the position of the maintenance portable terminal 20 and the reference atmospheric pressure. Good.

  The control device 1 may obtain the difference between the altitude at the position of the maintenance portable terminal 20 and the altitude of the reference floor. In this case, the control device 1 holds the reference atmospheric pressure in advance, and the maintenance portable terminal 20 transmits the value of the atmospheric pressure detected by the atmospheric pressure sensor 24 to the control device 1. And the control apparatus 1 calculates | requires the difference of the height of the position of the portable terminal 20 for a maintenance, and a reference | standard floor by the difference of the value of the atmospheric pressure which the atmospheric | air pressure sensor 24 detected, and the reference | standard atmospheric pressure. The atmospheric pressure value is detected for use in altitude calculation, but need not be converted to altitude. The difference in altitude between the position of the maintenance portable terminal 20 and the reference floor can be obtained directly from the difference (relative value) of the value that varies depending on the altitude such as atmospheric pressure.

  In this way, the terminal position calculation unit 25 can always obtain the position of the maintenance portable terminal 20. Specifically, the terminal position calculation unit 25 obtains the latitude and longitude of the position of the maintenance portable terminal 20, the distance from the wireless terminal 4 of the maintenance portable terminal 20, and the altitude of the position of the maintenance portable terminal 20. Can do. Further, the terminal position calculation unit 25 determines on which floor of the building the maintenance portable terminal 20 is located, that is, the maintenance portable terminal 20 from the difference between the altitude of the position of the maintenance portable terminal 20 and the altitude of the reference floor. You can ask what floor of the building the maintenance staff you have.

  FIG. 3 is a flowchart for explaining the operation of the elevator maintenance inspection support system according to this embodiment. In the monitoring center 11, the position of the elevator 30 that performs the maintenance inspection work, the scheduled maintenance inspection date and time, and the identification signal set in the maintenance portable terminal 20 possessed by the maintenance staff are recorded in advance. When a plurality of maintenance mobile terminals 20 are used for maintenance inspection work, such as when a plurality of maintenance personnel perform maintenance inspection work, the identification signal set for each of the maintenance mobile terminals 20 is a monitoring center. 11 is recorded.

  In S1, the monitoring center 11 determines whether the current date and time is a predetermined time before the planned maintenance date and time. If the current date and time is a predetermined time before the scheduled maintenance date and time, the process proceeds to S2. The predetermined time can be arbitrarily determined in advance, and can be set to, for example, one hour.

  In S <b> 2, the monitoring center 11 requests the mobile phone base station 12 to acquire the position (latitude and longitude) of the maintenance portable terminal 20 having the identification signal recorded in the monitoring center 11. The mobile phone base station 12 acquires the position of the maintenance mobile terminal 20 obtained from the GPS signal by the maintenance mobile terminal 20 and transmits it to the monitoring center 11. The monitoring center 11 determines the distance between the elevator 30 and the maintenance portable terminal 20 from the position (latitude and longitude) of the elevator 30 performing the maintenance inspection work and the position of the maintenance portable terminal 20 acquired from the maintenance portable terminal 20. calculate. This distance is a distance obtained from latitude and longitude, that is, a horizontal distance.

  In S3, the monitoring center 11 determines whether the distance between the elevator 30 and the maintenance portable terminal 20 is equal to or less than a predetermined distance. If the distance between the elevator 30 and the maintenance mobile terminal 20 is equal to or less than the predetermined distance, it is considered that the maintenance staff possessing the maintenance mobile terminal 20 has arrived at the building where the elevator 30 is installed, and the process proceeds to S4. This predetermined distance can be arbitrarily determined.

  In S <b> 4, the monitoring center 11 transmits the position of the elevator 30, the scheduled maintenance inspection date and the identification signal of the maintenance portable terminal 20 possessed by the maintenance staff to the control device 1. The control device 1 records the information received from the monitoring center 11 in the storage unit 1a. Then, the control device 1 will soon perform maintenance and inspection work for the elevator 30 on the in-car display device 2a of the car 2 and the landing display device 3 of the landing 40 while continuing the normal operation that is the current operation of the elevator 30. A message for notifying that to do is displayed alternately with a message displayed during normal operation. An example of a warning message for maintenance and inspection work is “Maintenance will be performed in 10 minutes. Please use another elevator”.

  In S5, the control device 1 determines whether the maintenance staff has arrived at the maintenance / inspection work site of the elevator 30 at the scheduled maintenance / inspection date / time. If the maintenance staff arrives at the maintenance / inspection work site of the elevator 30 and the current date / time is the scheduled maintenance / inspection date / time, it is considered that the maintenance staff has arrived at the maintenance / inspection work site of the elevator 30 at the scheduled maintenance / inspection date / time. move on.

  Whether or not the maintenance staff has arrived at the maintenance inspection work site of the elevator 30 is determined as follows. If the maintenance portable terminal 20 performing wireless communication with the wireless terminal 4 has the identification signal transmitted from the monitoring center 11 in S4, the control device 1 continues the wireless communication with the maintenance portable terminal 20. If not, the wireless communication with the maintenance portable terminal 20 is stopped. As described above, the maintenance portable terminal 20 can determine the distance between the maintenance portable terminal 20 and the wireless terminal 4 and the difference between the altitude of the position of the maintenance portable terminal 20 and the altitude of the reference floor. The maintenance portable terminal 20 controls the distance between the maintenance portable terminal 20 and the wireless terminal 4 and the difference between the height of the position of the maintenance portable terminal 20 and the height of the reference floor via the wireless terminal 4. 1 to send. In the control device 1, the distance between the maintenance portable terminal 20 and the wireless terminal 4 is not more than a predetermined distance, and the difference between the altitude of the position of the maintenance portable terminal 20 and the altitude of the reference floor is not more than a predetermined value. If so, it is determined that the maintenance staff has arrived at the maintenance inspection work site. If the difference between the altitude at the position of the maintenance mobile terminal 20 and the altitude of the reference floor is equal to or less than the predetermined value, it can be considered that the maintenance staff possessing the maintenance mobile terminal 20 is on the reference floor. Note that the predetermined distance and the predetermined value can be arbitrarily determined in advance, and the predetermined distance is different from the predetermined distance used in S3.

  In determining whether or not the current date and time is the scheduled maintenance and inspection date and time, even if the current date and time is not exactly the same as the scheduled maintenance and inspection date and time, the current date and time If it is between the date and time after the time, the current date and time may be determined to be the scheduled maintenance inspection date and time. The predetermined time can be arbitrarily determined in advance. For example, if the current date is between 10 minutes before and after the scheduled maintenance inspection date, the current date may be determined to be the scheduled maintenance inspection date. . Or, if the scheduled maintenance inspection date and time is set in the form of a time range with a time range, and if the current date and time is included in this time range, the current date and time is determined to be the scheduled maintenance inspection date and time. Also good. The width of this time can be arbitrarily determined in advance.

  In S <b> 6, the control device 1 determines whether there are passengers in the elevator 30. When a call is registered by operating a landing call button in the landing 40 or a destination floor button in the car 2, it is determined that there is a passenger and normal operation of the elevator 30 is continued. If the call is not registered for a predetermined time, it is determined that there is no passenger and the process proceeds to S7. This predetermined time can be arbitrarily determined in advance.

  In S7, the control device 1 moves the car 2 to the reference floor and stops the operation of the elevator 30. And the control apparatus 1 displays only the notice message of the maintenance inspection work displayed by S4 on the in-car display device 2a of the car 2 and the landing display device 3 of the landing 40 (the message displayed during normal operation is not displayed). ).

  The elevator 30 in which the car 2 has moved to the reference floor in S7 has been determined that there are no passengers in S6, and since a warning message for the maintenance inspection work is displayed, preparations for the maintenance inspection work have already been made. ing. Thus, in the elevator maintenance / inspection support system according to the present embodiment, preparation for maintenance / inspection work can be automatically performed in advance.

  In S8, the control device 1 monitors whether the call is registered by operating the landing call button of the landing 40 or the destination floor button in the car 2. Although it is determined that there are no passengers in S6, passengers may appear before the maintenance staff starts the maintenance and inspection work, so the process of S8 is executed to confirm that there are no passengers. When the call is registered, since there is a driving request for the elevator 30, the control device 1 performs the maintenance displayed in S7 on the in-car display device 2a of the car 2 and the landing display device 3 of the landing 40. A warning message for inspection work and a message to be displayed during normal operation are alternately displayed and the elevator 30 is operated. Monitoring by the control device 1 as to whether or not a call is registered continues until maintenance personnel start maintenance and inspection work.

  In S9, the maintenance staff who has arrived at the maintenance / inspection work site of the elevator 30 starts the maintenance / inspection work according to the determined procedure. When the maintenance staff starts the maintenance / inspection work, the control device 1 displays a message notifying that the elevator 30 is under maintenance / inspection work on the in-car display device 2a of the car 2 and the landing display device 3 of the landing 40. .

  Even if the current date / time is not exactly the same as the scheduled maintenance / inspection date / time, if the current date / time is between the date / time before the scheduled maintenance / inspection time and the date / time after the predetermined time (for example, If the current date / time is between 10 minutes before and after the scheduled maintenance date / time), it can be implemented. Alternatively, when the scheduled maintenance inspection date and time is set in the form of a time range, if the current date and time is included in this time range, the maintenance inspection work can be performed.

  The maintenance staff performs maintenance and inspection work using the maintenance and inspection application 26 installed in the maintenance portable terminal 20. At the time of maintenance / inspection work, the maintenance portable terminal 20 performs wireless communication with the wireless terminal 4 and connects to the control device 1. As a security measure for connection by wireless communication, a maintenance staff may input his / her ID and password to the maintenance portable terminal 20 when connection between the maintenance portable terminal 20 and the control device 1 is started.

  When the maintenance inspection work is completed, the maintenance staff operates the maintenance portable terminal 20 to register the next maintenance inspection scheduled date and time in the storage unit 1a of the control device 1. The control device 1 transmits the next scheduled maintenance inspection date and time registered in the storage unit 1 a to the monitoring center 11.
