Definitions
- This disclosure relates to a method for rewriting an elevator control program.
- the elevator control program is rewritten to change the control by adding new functions or to improve the control function.
- an update file for updating the current control program to the new control program is generated on the maintenance company's information processing device based on the current control program and the new control program.
- the created update file is sent to the target elevator using a communication line.
- the received update file may disappear, and you may need to have the update file sent again.
- the objective of this disclosure is to provide a method for rewriting an elevator control program that makes it easy to update the control program in a short time without waiting time when a maintenance worker visits the site, and that makes it difficult to accidentally lose updated files.
- the method of rewriting an elevator control program includes the steps of connecting an information terminal to an elevator control panel and importing identification information capable of identifying a current control program before updating from the control panel to the information terminal, transmitting the identification information from the information terminal to an information processing device, creating or selecting an update file for the information processing device to rewrite the current control program with the new control program based on the current control program identified by the information processing device based on the identification information and a new control program resulting from the update of the current control program, importing the update file into the information terminal, and rewriting the current control program stored in the control panel with the new control program based on the update file imported into the information terminal.
- the identification information may be any information that is linked to the target control program and can identify (specify) the target control program, such as information about the name of the control program.
- the maintenance worker After the maintenance worker arrives at the site, he or she connects (accesses) an information terminal to the control panel and obtains identification information from the control panel (control device) that can identify the current control program, thereby starting the rewriting of the current control program. Therefore, unlike the rewriting of the control program in the reference example, there is no situation in which the maintenance worker is unable to start work until the update file has been sent to the elevator, and there is no waiting time for the maintenance worker when he or she arrives at the site.
- the identification information may also be transmitted from the information terminal to the information processing device while the information terminal is connected to the control panel.
- This configuration makes it easy to quickly perform program rewrite operations.
- the method may also include a step in which the information terminal writes the update file to a communication control device connected to the control panel, and a step in which the current control program stored in the control panel is rewritten with the new control program based on the update file written to the communication control device based on a signal transmitted by the information terminal to the communication control device or the control panel.
- the step of rewriting the current control program with the new control program may be performed manually by a person operating an information terminal, or may be performed automatically by a control device of the information terminal without human operation.
- the information terminal may also write the update file to the communication control device when it determines, based on elevator identification information stored in the communication control device, that the communication control device is connected to the elevator for which the current control program is to be rewritten.
- the elevator identification information may be, for example, information about the elevator's serial number or information indicating which building the elevator is in and which elevator number it is in.
- an update file for rewriting the current control program with the new control program may be created in the information processing device, and the created update file may be stored in the information processing device.
- the identification information may also be transmitted from the information terminal to the information processing device via a mobile phone.
- This configuration makes it easy to transmit identification information to an information processing device regardless of the Internet connection environment at the location where the elevator is located.
- the communication control device may also be capable of connecting to the information processing device without going through the information terminal.
- the update file can be sent from the information processing device to the communication control device, and the current control program can be updated.
- the elevator control program rewriting method disclosed herein makes it easy to update the control program in a short time since there is no waiting time when a maintenance worker visits the site, and it is difficult to accidentally lose the updated file.
- FIG. 1 is a schematic configuration diagram of a program rewriting system according to an embodiment of the present disclosure.
- 4 is a flowchart showing an example of a procedure for rewriting a control program of an elevator by the above-mentioned program rewriting system.

- the communication control device 11 is composed of a CCU (communication control unit) and connects the computer system to a communication line.
- the communication control device 11 has the function of detecting errors that occur when transmitting data and converting data into bits and characters.
- the communication control device client 12 requests various information regarding communication from the communication control device 11 and stores that information.
- the machine reception registration client 15 receives and stores information indicating that information has been received from the machine.
- the command system 17 includes, for example, a terminal that enables a person in the information center 5 to communicate with a person 52 in the car 51 of an elevator 50 in the event of a disaster.
- the router 18 analyzes information from the network layer (Internet layer, layer 3) of the protocol hierarchy to determine whether data can be forwarded and to which destination, mainly relaying data in TCP/IP networks such as the Internet.
- the router 18 analyzes data (packets) received from the connection destination and controls forwarding based on IP (Internet Protocol) control information.
- IP Internet Protocol
- the router 18 performs routing, selects an appropriate forwarding route from the destination IP address of the packet, and determines which neighboring device the packet should be forwarded to next before transmitting the packet.
- the router 18 performs route selection, for example, by referring to a routing table.
- the routing table lists which device should be requested to relay for each destination network (address), and finds the forwarding destination corresponding to the destination address and forwards the packet to that device.
- the service system 30 includes, for example, a router 31 and an information processing device 32.
- the router 31 has a similar configuration to the router 18 and performs the same operations as the router 18.
- the devices 31 and 32 of the service system 30 are connected to each other via a local area network of the service base 7.
- Each elevator 50 includes a car 51, a control panel 53, a hoist 55, a deflector 56, a counterweight 57, a wire rope 58, and a communication control device 59.
- One end of the wire rope 58 is connected to the car 51, and the other end of the wire rope 58 is connected to the counterweight 57.
- the wire rope 58 is wound around the hoist 55 and the deflector 56, and connects the car 51 and the counterweight 57.
- control panel 53 controls the hoist motor and the car door opening and closing motor based on information from an encoder, a floor landing sensor, a car call button installed at the landing, and a destination floor designation button in the car (not shown), thereby controlling the lifting and lowering of the car 51 and the opening and closing of the car doors.
- the communication control device 59 has the same functions as the communication control device 11 and performs the same operations as the communication control device 11.
- the communication control device 59 is provided to communicate between the control panel 53 and devices outside the elevator 50.
- the communication control device 59 is also connected to the intercom device 54 inside the car 51.
- the control panel 53 of each elevator 50 is capable of communicating with the information processing system 10 through a communication control device 59, and is also capable of communicating with the service system 30 via routers 18, 31.
- the communication line between the control panel 53 and the information processing system 10 may include a telephone line 8 or an optical line.
- the information terminal 70 is, for example, a notebook computer that is suitable for carrying around.
- the information terminal 70 communicates with the communication control device 59 using a wired or wireless connection, for example, Wi-Fi (registered trademark), etc.
- the information terminal 70 is configured to tether with a mobile phone (e.g., a smartphone) 71 via Wi-Fi or Bluetooth (registered trademark), and can connect to the Internet by using the mobile phone 71 as an access point to which the information terminal 70 can connect.
- the mobile phone 71 is, for example, the mobile phone of a maintenance worker who carries the information terminal 70.
- the mobile phone 71 and the information processing device 32 communicate with each other via LTE (Long Term Evolution). For this reason, the information terminal 70 communicates with the information processing device 32 via the mobile phone 71. It is also possible to insert a SIM card (not shown) into the mobile terminal and communicate directly from the mobile terminal.
- the program rewriting system 1 rewrites the control program of the elevator 50, for example, in the following procedure. Note that the control program is rewritten, for example, when a new function is added to the elevator 50, or to improve the control function of the elevator 50, etc.
- FIG. 2 is a flowchart showing an example of a procedure for rewriting the control program of the elevator 50 by the program rewriting system 1.
- rewriting of the control program starts when a maintenance worker arrives at the site and connects the information terminal 70 to the communication control device 59 by wire or wirelessly.
- identification information capable of identifying the current control program before the update from the control panel 53 is imported into the information terminal 70 via the communication control device 59.
- the identification information may be any information that is linked to the target current control program and can identify (specify) the target current control program, such as information about the name of the program.
- the identification information of the current control program before the update may be imported directly from the control panel 53 to the information terminal 70 without going through the communication control device 59.
- step S2 the information terminal 70 transmits the identification information to the information processing device 32 via the mobile phone 71.
- step S3 the control device of the information processing device 32 references the identification information to determine whether or not an update file capable of updating the current control program to the corresponding new control program is stored in the storage unit of the information processing device 32. If a positive determination is made in step S3, the process proceeds to step S4, in which the information processing device 32 transmits the update file to the information terminal 70 via the mobile phone 71.
- step S5 the process proceeds to step S5, where the information processing device 32 creates an update file, i.e., a difference file (a file capable of identifying code portions that differ between the two control programs), based on the current control program identified from the identification information and the corresponding new control program.
- the information processing device 32 creates an update file (a difference file between the current control program and the new control program) that can rewrite the current control program with the new control program.
- step S6 the control device of the information terminal 70 determines whether or not the update file can be written to the communication control device 59.
- the communication control device 59 is connected to the control panel 53, and the memory unit of the communication control device 59 stores elevator identification information capable of identifying the corresponding elevator 50, such as the serial number of the elevator 50 and the access number (a number that identifies which building and which elevator number it is).
- the information terminal 70 checks whether or not the corresponding control program in the corresponding elevator 50 is a control program that requires rewriting of the control program.
- information on the elevator 50 that requires rewriting of the control program may be stored in the memory unit of the information terminal 70.
- step S6 If a negative judgment is made in step S6, the update file is not written to the communication control device 59, and control ends. On the other hand, if a positive judgment is made in step S6, the process proceeds to step S7, and the information terminal 70 writes the update file to the memory unit of the communication control device 59. In the following step S8, the information terminal 70 transmits a signal to the communication control device 59 indicating that the update file is to be reflected in the current control program of the control panel 53, and the current control program of the control panel 53 is rewritten with the new control program based on the control of the control device of the communication control device 59, and control ends.
- step S8 the information terminal 70 may send a signal to the control panel 53 indicating that the update file stored in the communication control device 59 is to be reflected in the current control program.
- the control panel 53 may then request information about the update file from the communication control device 59, and the control panel 53 may rewrite the current control program based on the update file provided by the communication control device 59.
- the information terminal 70 may send a signal to the communication control device 59, causing the communication control device 59 to send information about the update file to the control panel 53, or the information terminal 70 may send a signal to the control panel 53, causing the control panel 53 to obtain information about the update file from the communication control device 59.
- the method of rewriting an elevator control program includes the steps of connecting the information terminal 70 to the control panel 53 of the elevator 50 and importing identification information (e.g., program name) capable of identifying the current control program before the update from the control panel 53 to the information terminal 70, transmitting the identification information from the information terminal 70 to the information processing device 32, creating or selecting an update file for the information processing device 32 to rewrite the current control program with the new control program based on the current control program identified by the information processing device 32 based on the identification information and the new control program after the current control program is updated, importing the update file into the information terminal 70, and rewriting the current control program stored in the control panel 53 with the new control program based on the update file imported into the information terminal 70.
- identification information e.g., program name
- the information terminal 70 is connected (accessed) to the control panel 53, and the rewriting of the current control program is started by obtaining identification information from the control panel 53 that can identify the current control program. Therefore, unlike the rewriting of the control program in the reference example described above, there is no situation in which the maintenance worker cannot start work until the update file has been sent to the elevator 50, and there is no waiting time for the maintenance worker when he or she arrives at the site.
- identification information may be transmitted from the information terminal 70 to the information processing device 32 while the information terminal 70 is connected to the control panel 53.
- This configuration makes it easy to quickly perform program rewrite operations.
- the method may also include a step in which the information terminal 70 writes an update file to the communication control device 59 connected to the control panel 53, and a step in which the information terminal 70 rewrites the current control program stored in the control panel 53 with a new control program based on the update file written to the communication control device 59 based on a signal transmitted by the information terminal 70 to the communication control device 59 or the control panel 53.
- the step of rewriting the current control program with the new control program may be performed manually by a person operating the information terminal 70, or may be performed automatically by the control device of the information terminal without human operation.
- the update file imported into the information terminal 70 is reflected in the current control program of the control panel 53 in two stages. This makes it possible to check whether the update is accurate, reducing the possibility of erroneous rewriting.
- the information terminal 70 may write an update file to the communication control device 59 when it determines, based on the elevator identification information stored in the communication control device 59, that the communication control device 59 is connected to the elevator 50 for which the current control program is to be rewritten.
- an update file for rewriting the current control program with a new control program may be created in the information processing device 32, and the created update file may be stored in the information processing device 32.
- the identification information may also be transmitted from the information terminal 70 to the information processing device 32 via the mobile phone 71.
- This configuration makes it easy to transmit identification information to the information processing device 32 regardless of the Internet connection environment at the location where the elevator 50 is located.
- the communication control device 59 may also be connectable to the information processing device 32 without going through the information terminal 70. More specifically, as shown in FIG. 1, the communication control device 59 may be connectable to the information processing device 32, for example, through the telephone line 8, the information processing system 10, and the routers 18 and 31.
- the update file can be sent from the information processing device 32 to the communication control device 59, and the current control program can be updated.
- the information terminal 70 transmits the identification information of the current control program to the information processing device 32 while the information terminal 70 is connected to the control panel 53.
- the information terminal may transmit the identification information of the current program to the information processing device while the information terminal is disconnected from the control panel.
- the information terminal 70 writes an update file to the communication control device 59 when it determines, based on the elevator identification information stored in the communication control device 59, that the communication control device 59 is connected to the elevator 50 for which the current control program is to be rewritten.
- the information terminal may always write the update file to the communication control device without referring to the elevator identification information stored in the communication control device.
- the information terminal 70 writes the update file to the communication control device 59 connected to the control panel 53.
- the information terminal may also write the update file directly to the control panel.
- an update file for rewriting the current control program with a new control program is created in the information processing device 32, and the created update file is stored in the information processing device 32.
- the update file created by the information processing device does not have to be stored in the storage unit of the information processing device.
- an update file may always be created when the information processing device receives identification information that can identify the current control program. In this way, the amount of information stored in the information processing device can be reduced.
- the identification information is transmitted from the information terminal 70 to the information processing device 32 via the mobile phone 71.
