The drive circuit 68 includes an inverter circuit 72 connected to the motor 20 and a drive control circuit 70 that controls the inverter circuit 72.

  The control unit 80 operates based on the control program and control data stored in the storage unit 82, and performs normal operation, power saving operation, stop, and the like of the escalator 10 by this control program. The operation start and the operation end are performed based on control data such as an operation start time and an operation end time stored in the storage unit 82 separately from the program. This control program also includes an update program for updating its own control program. Further, the storage unit 82 stores the version (for example, version 3.02) of the currently operating control program, and further stores identification information of the escalator 10. This “identification information” is information such as numbers, codes, characters, etc., for identifying other escalators 10 and their own escalators 10.

  The server 100 is connected to the control unit 80 via communication of the communication unit 84. This server 100 is connected to a monitoring device for maintenance personnel provided at a remote location from the building 1 where the escalator 10 is provided. The server 100 is provided to update a control program for a plurality of escalators 10 at remote locations to the latest version of the control program, and an update program (for example, JOB) for updating an old control program to the latest control program. The control program to which the management number is added is transmitted to the control unit 80 of each escalator 10 through the Internet line or public line.

The skirt guard pinching detection device is a device that detects that a foreign object (for example, clothes or luggage) is pinched between the skirt guard 44 and the step 30, and the inlet pinching detection device is a handrail belt 38. Is a device that detects when a foreign object (for example, a passenger's hand or baggage) is simultaneously drawn into the inlet part 46 or the inlet part 48.

(3) Update of Control Program Next, an operation state of updating the control program of the escalator 10 based on FIGS. 3 and 4 will be described based on the flowcharts of FIGS. 3 and 4. FIG. 3 shows an operation state of the control program of the escalator 10, and this operation state is executed based on the control program. FIG. 4 is a flowchart showing the operating state of the server 100.

  In step S1, the control unit 80 measures the current time. When the current time reaches the operation start time, the control unit 80 starts the operation of the escalator 10, and proceeds to step S2.

  In step S2, the control unit 80 causes the escalator 10 to perform normal operation, that is, causes the step 30 to travel at a normal travel speed V1 and a normal acceleration α1, and proceeds to step S3.

  In step S3, the control unit 80 proceeds to step S4 when a confirmation signal for confirming the version of the current control program is received from the server 100 via the communication unit 84 (in the case of y), and proceeds to step S5 if not received. Go (if n).

  In step S4, since the control unit 80 has received the confirmation signal from the server 100, the control unit 80 calls the version of the current control program from the storage unit 82 to the server 100 and transmits the version information together with the identification information using the communication unit 84. Proceed to step S5. The version information refers to information including the name of the control program, the version of the control program, and the year, date, and time updated to the version.

  In step S5, the control unit 80 checks whether or not the current time being measured is the operation end time, and if it is not the operation end time, the process returns to step S2 (in the case of n), and the operation end time is reached. If YES, the process proceeds to step S6 (in the case of y).

  In step S6, the control unit 80 checks whether or not the update program is transmitted from the server 100 during normal operation and stored in the storage unit 82, and if stored, proceeds to step S7 (in the case of y). If there is no update program, the process returns to step S1 (in the case of n). Note that the control unit 80 always receives the transmission of the update program from the server 100 during normal operation, and stores the update program in the storage unit 82 when the update program is received.

  In step S7, the control unit 80 updates the control program based on the update program, and proceeds to step S8 when the update is completed.

  In step S8, the control unit 80 performs a test operation of the escalator 10 based on the updated control program, and confirms whether or not the updated control program operates normally. At this time, the test operation is performed after the operation end time. However, since there is a possibility that the passenger is on the step 30 of the escalator 10, the travel speed V2 of the step 30 in the test operation is higher than the travel speed V1 of the normal operation. This is performed at a low traveling speed V2 and a low acceleration α2. That is, V1> V2> 0 and α1> α2> 0. Then, the process proceeds to step S9.

  In step S9, if the control unit 80 receives an error signal from each device such as the safety device 74, the storage unit 82, and the communication unit 84 during the test operation, the process proceeds to step S10 (in the case of y) and receives the error signal. If not, the process proceeds to step S11 (in the case of n).

  In step S10, the control unit 80 determines that the update of the control program has not been performed correctly because the error signal is received, and transmits the update error signal together with the identification information to the server 100 and ends. In addition, the control part 80 after this does not start the operation of the escalator 10 even if it becomes an operation start time on the next day, and stops the escalator 10 until a maintenance person checks and repairs.

  In step S11, since the control unit 80 did not receive the error signal during the test operation, the control unit 80 transmits an update completion signal indicating that the update of the control program has been normally completed to the server 100 together with the identification information, and proceeds to step S12. .

  In step S12, the control unit 80 updates the version information of the control program stored in the storage unit 82 to the latest version, and returns to step S1.

  Next, the operation state of the server 100 will be described based on the flowchart of FIG.

  In step S21, the server 100 transmits all confirmation signals to the escalator 10 managed by the server 100, and proceeds to step S22.

  In step S22, the server 100 receives the version information and identification information of the control program from each escalator 10, and proceeds to step S23.

  In step S23, the server 100 compares the version of the control program in the version information for each piece of identification information with the latest version of the control program, extracts only the escalator 10 that is not the latest version, and proceeds to step S24 (y in the case of). If the latest version of the control program is used in all the escalators 10, the process ends (in the case of n).

  In step S24, the server 100 transmits the update program to the escalator 10 having identification information that needs to be updated, and the process proceeds to step S25.

  In step S25, the server 100 proceeds to step S26 when the update error signal and the identification information are received, and proceeds to step S27 when they are not received (in the case of n).

  In step S26, the server 100 transmits the identification information having received the update error signal to the monitoring apparatus as an alarm signal, and the process ends. When the monitoring device receives the warning signal, the maintenance staff visits the site, and after the escalator 10 is inspected and repaired, the maintenance work is performed again.

  In step S27, the server 100 ends the update operation for the escalator 10 having the identification information that has received the update completion signal.

(4) Effect According to the present embodiment, the escalator 10 can be automatically updated to the latest version based on the update program from the server 100 if it is not the latest version of the control program, and then automatically performs test operation. You can check whether it is done normally.

  Further, during the test operation, the traveling speed V2 and acceleration α2 of the step 30 are set slower than the normal traveling speed V1 and acceleration α1, so that even when the passenger is on the step 30, the passenger is safe.

  Further, when the update is normally completed, the control unit 80 can update the version stored in the storage unit 82. Further, the control unit 80 can notify the server 100 that the update has been normally completed.

  Further, when the update is not completed normally, the control unit 80 transmits an update error signal to the server 100 and stops the operation of the escalator 10, so that the safety of the passenger can be ensured.

(5) Modification Example In the above embodiment, the server 100 transmits a confirmation signal and receives version information from each escalator 10 in order to detect the version of each escalator 10. However, instead of this, the server 100 manages the identification information and version information of each escalator 10 in correspondence with each other, and if the managed version is old without sending a confirmation signal, the update is performed. The program may be transmitted to the control unit 80 of the escalator 10 operating with the old version of the control program.

  In the above embodiment, the update program can be received during the normal operation of the escalator. Instead, after the operation of the escalator 10 is completed, the control unit 80 transmits an operation completion signal to the server 100. When the server 100 receives the operation completion signal, the server 100 may transmit an update program to the control unit 80 of the escalator 10.

  Further, in the above embodiment, the description has been made by adapting to the step 30 of the escalator 10, but instead of this, it may be adapted to a step (step) of a moving sidewalk.

  Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit 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.
