Description

TECHNICAL FIELD

[0001] The present disclosure relates to a rewriting method of a control program of an elevator. BACKGROUND

[0002] As described in Patent Literature 1, the control program of an elevator is rewritten for control change based on addition of new functions, control function improvement, and the like.

[0003] PRIOR ART DOCUMENTS

[0004] PATENT LITERATURE

[0005] Patent Literature 1: Japanese Patent Application Publication No. 2007-1734 SUMMARY

[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] In this background, it is considered that the rewriting of the control program of an elevator is performed by the rewriting process of the control program of the reference example described below using a communication line. In addition, the rewriting process of the control program of the reference example is not disclosed in documents and is not known in the art, and cannot be used to deny the patentability of the present application.

[0008] In the rewriting of the control program of the reference example, first, based on the current control program and the new control program, an update file for updating the current control program to the new control program is generated in an information processing device of a maintenance company. Next, the created update file is transmitted to the target elevator using a communication line.

[0009] Finally, when the maintenance work personnel visits the elevator, the case where the update file has been transmitted to the elevator is confirmed, and using an information terminal, the current control program is rewritten to the latest control program using the update file.

[0010] In this way, each preparation for the rewriting of the program at the site can be saved, and the waiting time can also be reduced. However, in the case where the target elevator is a plurality of, for example, tens of thousands, the communication takes time, and it is expected that the transmission of the update file is not completed when the maintenance work personnel visits the site.

[0011] In addition, it is also possible that another work is performed before the reception of the update file is confirmed, and thus the received update file disappears, and the update file needs to be transmitted again.

[0012] Therefore, an object of the present disclosure is to provide a rewriting method of a control program of an elevator, which does not have waiting time when a maintenance work personnel visits a site, and easily updates the control program in a short time, and is not likely to accidentally cause the update file to disappear.

[0013] MEANS FOR SOLVING THE PROBLEMS

[0014] To solve the above problems, the rewriting method of the control program of the elevator of the present disclosure includes the steps of connecting an information terminal to a control panel of an elevator, taking in, from the control panel to the information terminal, identification information capable of identifying a current control program before update; transmitting the identification information from the information terminal to an information processing device; creating or selecting, by the information processing device, an update file for rewriting the current control program to a new control program after update of the current control program, based on the current control program determined by the information processing device based on the identification information and the new control program; taking in the update file to the information terminal; and rewriting the current control program stored in the control panel to the new control program based on the update file taken in to the information terminal.

[0015] In addition, the identification information can be any information capable of identifying (determining) the control program as an object in association with the control program as an object, such as information of the name of the control program, and the like.

[0016] According to the present disclosure, after the maintenance work person arrives at the site, the information terminal is connected (accessed) to the control panel, and the identification information capable of identifying the current control program is taken in from the control panel (control device), whereby the rewriting of the current control program is started. Therefore, unlike the rewriting of the control program of the reference example, it does not fall into a situation where the work of the maintenance work person cannot be started until the transmission of the update file to the elevator is completed, and the waiting time of the maintenance work person who arrives at the site is not generated.

[0017] Further, after the maintenance work person arrives at the site, only the update file related to the elevator is taken in from the information processing device to the information terminal, and therefore, unlike the rewriting of the control program of the reference example, tens of thousands of control programs are not transmitted at the same time, and the communication time can be greatly shortened. Also, unlike the rewriting of the control program of the reference example, the maintenance work person participates in the entire update operation of the current control program, and therefore, the situation where the maintenance work person erroneously cuts off the power of the elevator in the update of the current control program is less likely to occur, and the update file is less likely to disappear in the update operation of the current control program. Therefore, according to the rewriting method of the control program of the present disclosure, there is no waiting time when the maintenance work person visits the site, the control program is easily updated in a short time, and the update file is less likely to be accidentally deleted.

[0018] Further, it can also be that the identification information is transmitted from the information terminal to the information processing device in a state where the information terminal is connected to the control panel.

[0019] According to the present structure, the program rewriting operation is easily and quickly performed.

[0020] Further, the information terminal can write the update file to the communication control device connected to the control panel, and the current control program stored in the control panel can be rewritten to the new control program based on the update file written to the communication control device according to a signal transmitted from the information terminal to the communication control device or the control panel.

[0021] Further, the step of rewriting the current control program to the new control program can be performed manually by a person operating the information terminal, or can be performed automatically by the control device of the information terminal without the operation of a person.

[0022] According to the present structure, the update file taken into the information terminal is reflected to the current control program of the control panel in two stages. Therefore, it is possible to confirm whether the update is correct, and it is possible to reduce the possibility of erroneous rewriting.

[0023] Further, the information terminal can write the update file to the communication control device connected to the control panel, and the current control program stored in the control panel can be rewritten to the new control program based on the update file written to the communication control device according to a signal transmitted from the information terminal to the communication control device or the control panel.

[0024] Further, the elevator identification information can be, for example, information of a serial number of the elevator, information indicating the number of machines of a building where the elevator is located, or the like.

[0025] According to the present structure, the rewriting of the current control program can be performed on the basis of the fact that the elevator in which the rewriting of the current control program is performed is an elevator in which the rewriting of the current control program is required. Therefore, it is possible to prevent erroneous rewriting of the control program.

[0026] Further, the information processing device can create an update file for rewriting the current control program to the new control program, and store the created update file in the information processing device.

[0027] According to the present structure, when the control program of the same kind of elevator is updated, an update file for updating the control program of the first elevator is created only once, and when the control program of another elevator of the same kind is updated, the created update file can be used to update the control program. Therefore, the update of the control program of the above-mentioned other elevator can be performed in a short time.

[0028] Further, the identification information can be transmitted from the information terminal to the information processing device via a portable telephone.

[0029] According to the present structure, it is easy to transmit the identification information to the information processing device regardless of the network connection environment of the location where the elevator is located.

[0030] Further, the communication control device can be capable of connecting with the information processing device without going through the information terminal.

[0031] According to the present structure, even if some undesirable situation occurs in the transmission of the update file from the information processing device to the information terminal, the update file can be transmitted from the information processing device to the communication control device, and the update of the current control program can be performed.

[0032] Effects of the Invention

[0033] According to the method of rewriting the control program of the elevator of the present disclosure, there is no waiting time when the maintenance worker visits the site, the control program is easily updated in a short time, and it is not easy to accidentally delete the update file. BRIEF DESCRIPTION OF DRAWINGS

[0035] Figure 2 is a flowchart showing an example of a rewriting process of the program rewriting system with respect to the control program of the elevator. DETAILED DESCRIPTION

[0036] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Further, in the case where a plurality of embodiments, modifications, and the like are included below, it is assumed from the beginning that new embodiments are constructed by appropriately combining these feature portions. Further, among the structural elements described below, a structural element not described in the independent claim indicating the highest-order concept is an arbitrary structural element, and is not an essential structural element.

[0037] In addition, in the following description, the control device of each of the devices 11, 12, 15, 17, 18, 31, 32, 53, 70, and 71 is appropriately constituted by a computer, such as a microcomputer, and includes a control section and a storage section. The control section, that is, the processor, includes, for example, a CPU (Central Processing Unit). In addition, the storage section is constituted by a hard disk drive (HDD), a solid state drive (SSD), or the like, and can include a nonvolatile memory such as a ROM (Read Only Memory) and a volatile memory such as a RAM (Random Access Memory). In addition, the storage section can be constituted by only one storage medium, or can be constituted by a plurality of different storage media. The CPU reads out and executes a program or the like stored in advance in the storage section. In addition, the nonvolatile memory stores, in advance, a control program, a prescribed threshold value, or the like. In addition, the volatile memory temporarily stores a read-out program, processing data.

[0038] Figure 1 is a schematic configuration diagram of a program rewriting system 1 of one embodiment of the present disclosure. As shown in Figure 1 the program rewriting system (hereinafter referred to as a rewriting system) 1 has an information processing system 10 provided at an information center 5 of a maintenance company of elevators 50, a service system 30 provided at a service base 7 of the maintenance company, a plurality of elevators 50, an information terminal 70, and a portable telephone (smartphone) 71.

[0039] The information center 5 exists in a plurality of locations in Japan, for example. A plurality of information processing systems 10 provided at the plurality of information centers 5 manage, for example, data of machines including several ten-thousands of elevators 50 in Japan, effectively utilize the data, and perform repair of the machines, response to breakdown of the machines, and remote monitoring of the machines. The information processing systems 10 communicate using a wide area network (WAN) or a local area network (LAN).

[0040] The information processing system 10 includes, for example, a communication control device 11, one or more communication control device clients 12, a machine reception registration client 15, an instruction system 17, and a router 18. The respective devices 11, 12, 15, 17, and 18 of the information processing system 10 are connected to each other through a local area network of the information center 5. The communication control device 11 is configured of a CCU (communication control unit) and connects a computer system and a communication line. The communication control device 11 has a function of detecting an error generated at the time of transmission of data or converting data into bits or characters. The communication control device client 12 delegates various information related to communication from the communication control device 11 and stores the information.

[0041] The machine reception registration client 15 receives and stores information indicating that information has been received from a machine when the information is transmitted from the information processing system 10 to the machine. In addition, the instruction system 17 includes, for example, a terminal for a person in the information center 5 to talk to a person 52 in a car 51 of the elevator 50 at the time of a disaster or the like.

[0042] The router 18 relays data in a TCP / IP network such as the Internet, mainly performs routing, by analyzing information in the network layer (Internet layer, Layer 3) of the protocol layer to determine whether data can be transmitted, the destination of the transmission, and the like. The router 18 analyzes data (packets) received from a connection destination and performs transmission control based on control information of the IP (Internet Protocol). The router 18 performs routing by selecting an appropriate transmission path based on the destination IP address of the packet, determining the next destination from among adjacent devices, and transmitting the packet. The router 18 performs path selection, for example, by referring to a routing table. In the routing table, which device should be entrusted with relaying is listed for each network (address) of the destination, the transmission destination corresponding to the destination address is found, and the packet is transmitted to the device.

[0043] The service system 30 includes, for example, a router 31 and an information processing device 32. The router 31 has the same structure as the router 18 and performs the same operation as the router 18. The devices 31 and 32 of the service system 30 are connected to each other via the local area network of the service hub 7.

[0044] Each elevator 50 includes a car 51, a control panel 53, a traction machine 55, a diverting pulley 56, a counterweight 57, a rope 58, and a communication control device 59. One end of the rope 58 is connected to the car 51, and the other end of the rope 58 is connected to the counterweight 57. The rope 58 is wound around the traction machine 55 and the diverting pulley 56, linking the car 51 and the counterweight 57. Although not described in detail, the control panel 53 controls the traction machine motor and the car door opening and closing motor based on information from an encoder, a landing sensor, a car call button provided at a landing, and a destination floor designation button in the car, thereby performing lift control of the car 51, opening and closing control of the car door, and the like. The communication control device 59 has the same functions as the communication control device 11 and performs the same operation as the communication control device 11. The communication control device 59 is provided to enable communication between the control panel 53 and devices outside the elevator 50. The communication control device 59 is also connected to the intercom device 54 in the car 51.

[0045] The control panel 53 of each elevator 50 can communicate with the information processing system 10 via the communication control device 59 and can also communicate with the service system 30 via the routers 18 and 31. The communication line between the control panel 53 and the information processing system 10 can include the telephone line 8 or an optical line. The information terminal 70 is constituted by, for example, a notebook computer suitable for carrying. The information terminal 70 communicates with the communication control device 59 using a wired or wireless (e.g., Wi-Fi (registered trademark) or the like).

[0046] The information terminal 70 performs tethering with a portable telephone (for example, a smartphone) 71 based on Wi-Fi or Bluetooth (registered trademark), and enables the portable telephone 71 to connect to the Internet by setting the portable telephone 71 as an access point to which the information terminal 70 can connect. The portable telephone 71 is constituted by, for example, a portable telephone of a maintenance work person who carries the information terminal 70. The portable telephone 71 and the information processing apparatus 32 perform communication based on LTE (Long Term Evolution). Thus, the information terminal 70 performs communication with the information processing apparatus 32 via the portable telephone 71. In addition, a SIM card (not shown) can be inserted into the portable terminal, and communication can be performed directly from the portable terminal.

[0047] In the above configuration, the program rewriting system 1 rewrites the control program of the elevator 50, for example, in accordance with the following procedure. Further, rewriting of the control program is performed, for example, due to addition of a new function of the elevator 50, or in order to improve the control function of the elevator 50, and the like.

[0048] Figure 2 is a flowchart showing an example of a procedure of rewriting of the control program of the elevator 50 by the program rewriting system 1. Referring to Figure 2 , rewriting of the control program is started by the maintenance work person who has arrived at the site connecting the information terminal 70 to the communication control apparatus 59 in a wired or wireless manner, and first, in step SI, identification information capable of identifying the current control program before update is taken in from the control panel 53 to the information terminal 70 via the communication control apparatus 59. In addition, the identification information can be any information capable of identifying (determining) the current control program as an object in association with the current control program as an object, for example, information of the name of the program, and the like. In addition, the identification information of the current control program before update can also be taken in from the control panel 53 to the information terminal 70 directly without via the communication control apparatus 59.

[0049] Next, in step S2, the identification information is transmitted from the information terminal 70 to the information processing apparatus 32 via the portable telephone 71. Next, in step S3, the control apparatus of the information processing apparatus 32 determines whether or not an update file capable of updating the above current control program to a corresponding new control program is stored in the storage portion of the information processing apparatus 32 by referring to the identification information. When the determination in step S3 is affirmative, the processing proceeds to step S4, and the information processing apparatus 32 transmits the update file to the information terminal 70 via the portable telephone 71.

[0050] On the other hand, when the determination in step S3 is negative, the process proceeds to step S5, and the information processing device 32 creates an update file, i.e., a difference file (a file capable of specifying different code portions of the two control programs), based on the current control program determined from the identification information and the new control program corresponding thereto. In other words, the information processing device 32 creates an update file capable of rewriting the current control program to the new control program (a difference file of the current control program and the new control program). When step S5 ends, the process proceeds to step S4.

[0051] In step S6 following step S4, the control device of the information terminal 70 determines whether the update file can be written to the communication control device 59. Specifically, the communication control device 59 is connected to the control panel 53, and the communication control device 59 has stored in a storage section thereof elevator identification information capable of identifying the corresponding elevator 50, such as a serial number of the elevator 50, an access number (a number capable of specifying what kind of machine in what kind of building), and the like. The information terminal 70 confirms whether the corresponding control program in the corresponding elevator 50 is a control program requiring rewriting of the control program by referring to the elevator identification information. Here, information of the elevator 50 requiring rewriting of the control program can also be stored in the storage section of the information terminal 70.

[0052] When the determination in step S6 is negative, the writing of the update file to the communication control device 59 is not performed, and the control ends. On the other hand, when the determination in step S6 is affirmative, the process proceeds to step S7, and the information terminal 70 writes the update file to the storage section of the communication control device 59. In the following step S8, the information terminal 70 transmits a signal indicating reflection of the update file to the current control program of the control panel 53 to the communication control device 59, and the current control program of the control panel 53 is rewritten to the new control program based on the control of the control device of the communication control device 59, and the control ends.

[0053] Further, in step S8, the information terminal 70 can also transmit a signal indicating reflection of the update file stored in the communication control device 59 to the current control program to the control panel 53. Then, the control panel 53 can request information of the update file from the communication control device 59, and the control panel 53 performs rewriting of the current control program based on the update file provided from the communication control device 59. In short, in step S8, the signal can be transmitted to the communication control device 59 by the information terminal 70, the communication control device 59 transmits information of the update file to the control panel 53, or the signal can be transmitted to the control panel 53 by the information terminal 70, and the control panel 53 acquires information of the update file from the communication control device 59.

[0054] The rewriting method of the control program of the elevator according to the present disclosure includes the steps of connecting the information terminal 70 to the control panel 53 of the elevator 50, taking in, from the control panel 53 to the information terminal 70, identification information (e.g., program name) capable of identifying the current control program before update, transmitting the identification information from the information terminal 70 to the information processing device 32, creating or selecting, by the information processing device 32, an update file for rewriting the current control program to a new control program according to the current control program determined by the information processing device 32 based on the identification information and the new control program after update of the current control program, taking in the update file to the information terminal 70, and rewriting the current control program stored in the control panel 53 to the new control program based on the update file taken in to the information terminal 70.

[0055] According to the present disclosure, after the maintenance work person arrives at the site, the information terminal 70 is connected (accessed) to the control panel 53, the identification information capable of identifying the current control program is taken in from the control panel 53, and thus the rewriting of the current control program is started. Therefore, unlike the rewriting of the control program of the above-described reference example, it does not fall into a situation where the work of the maintenance work person cannot be started until the transmission of the update file to the elevator 50 is completed, and the waiting time of the maintenance work person who arrives at the site is not generated.

[0056] Further, after the maintenance work person arrives at the site, only the update file related to the elevator 50 as the program rewriting target is taken in from the information processing device 32 to the information terminal 70, and thus, unlike the rewriting of the control program of the above-described reference example, tens of thousands of control programs are not transmitted at the same time, and the communication time can be greatly shortened. Also, unlike the rewriting of the control program of the above-described reference example, the maintenance work person participates in the entire update operation of the current control program, and thus the situation where the maintenance work person erroneously cuts off the power of the elevator 50 in the update of the current control program is less likely to occur, and the update file is less likely to be lost in the update work of the current control program. Therefore, according to the rewriting method of the control program of the present disclosure, there is no waiting time when the maintenance work person visits the site, the control program is easily updated in a short time, and the update file is less likely to be lost by mistake.

[0057] In addition, it can also be that the identification information is transmitted from the information terminal 70 to the information processing device 32 in a state where the information terminal 70 is connected to the control panel 53.

[0058] According to the present structure, the program rewriting work is easily and quickly performed.

[0059] Further, the following steps can be included: the information terminal 70 writes the update file to the communication control device 59 connected to the control disk 53; and based on a signal sent from the information terminal 70 to the communication control device 59 or the control disk 53, the current control program stored in the control disk 53 is rewritten to the new control program based on the update file written to the communication control device 59.

[0060] Further, the step of rewriting the current control program to the new control program can be performed manually by a person operating the information terminal 70, or can be performed automatically by the control device of the information terminal without the aid of a person.

[0061] According to the present configuration, the update file taken in by the information terminal 70 is reflected in the current control program of the control disk 53 in two stages. Therefore, confirmation of whether the update is correct can be performed, and the possibility of an erroneous rewrite can be reduced.

[0062] Further, it can be that the information terminal 70 writes the update file to the communication control device 59 in a case where it is determined 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 that is performing the rewrite of the current control program.

[0063] According to the present configuration, the rewrite of the current control program can be performed on the basis of the fact that the elevator 50 that is performing the rewrite of the current control program is an elevator for which the rewrite of the current control program is required. Therefore, erroneous rewriting of the control program can be prevented.

[0064] Further, it can be that the update file for rewriting the current control program to the new control program is created in the information processing device 32, and the created update file is stored in the information processing device 32.

[0065] According to the present configuration, when updating the control program of the same kind of elevator 50, the update file for updating the control program of the first elevator 50 is created only once, and when updating the control program of other elevators of the same kind, the control program can be updated using the created update file. Therefore, the update of the control program of the above other elevators can be performed in a short time.

[0066] Further, the identification information can be sent from the information terminal 70 to the information processing device 32 via the portable telephone 71.

[0067] According to the present configuration, it is easy to send the identification information to the information processing device 32 regardless of the network connection environment of the location where the elevator 50 is located.

[0068] Further, it can be that the communication control device 59 can be connected to the information processing device 32 without passing through the information terminal 70. More specifically, as Figure 1As shown, the communication control device 59 can be connected to the information processing device 32 via, for example, the telephone line 8, the information processing system 10, and the routers 18, 31.

[0069] According to the present structure, even if some undesirable situation occurs in the transmission of the update file from the information processing device 32 to the information terminal 70, the update file can be transmitted from the information processing device 32 to the communication control device 59, and the update of the current control program can be performed.

[0070] Furthermore, the present disclosure is not limited to the above-described embodiments and modifications thereof, and various improvements and changes can be made within the scope of the matters described in the claims of the present application and equivalents thereof.

[0071] For example, in the above-described embodiments, the case where the identification information of the current control program is transmitted from the information terminal 70 to the information processing device 32 in a state where the information terminal 70 is connected to the control panel 53 was described. However, the identification information of the current program can be transmitted from the information terminal to the information processing device in a state where the connection between the information terminal and the control panel is cut off.

[0072] Furthermore, the case where the information terminal 70 writes the update file to the communication control device 59 in a case where it is determined 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 that performs the rewriting of the current control program was described. However, the information terminal can write the update file to the communication control device without referring to the elevator identification information stored in the communication control device.

[0073] Furthermore, the case where the information terminal 70 writes the update file to the communication control device 59 connected to the control panel 53 was described. However, the information terminal can directly write the update file to the control panel.

[0074] In addition, the case where the update file for rewriting the current control program to 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 was described. However, the update file created by the information processing device can not be stored in the storage section of the information processing device. Also, the update file can always be created when the information processing device receives the identification information capable of identifying the current control program. In this way, the information stored in the information processing device can be reduced.

[0075] Furthermore, the case where the identification information is transmitted from the information terminal 70 to the information processing device 32 via the cellular phone 71 was described. However, the identification information can be transmitted from the information terminal to the information processing device without going through the cellular phone, for example, the identification information can be transmitted from the information terminal to the information processing device via the communication control device.

[0076] Further, the case where the communication control device 59 is capable of connecting with the information processing device 32 without via the information terminal 70 is explained. However, the communication control device can connect with the information processing device only via the information terminal.

[0077] Further, the case where the information processing device 32 is contained in the service system 30 of the service site 7 is explained. However, the information processing device which receives the identification information of the current control program from the information terminal and transmits the update file to the information terminal can also be contained in the information processing system 10 of the information center 5.
